Patent Description:
With the development of the vessel industry, the workload of container loading and unloading operations is increasing. As large equipment for loading and unloading containers, quay cranes are increasingly used in various ports to achieve automated loading and unloading.

To prevent prohibited cargo from entering the territory through ports and ensure the safety of cargo in circulation, scanning inspection is usually performed on containers after cargo is unloaded. At present, generally after a container is unloaded by a quay crane, the container is transported by an AGV transfer trolley (or container transport truck) in a yard to a designated location to perform scanning inspection on the container. This requires a special area for scanning inspection at the port. Not only is a large space occupied, but also long time is consumed, and the circulation efficiency of the container at the port is low. Besides, dangerous prohibited articles may enter the yard, causing potential safety hazards.

In addition, due to limited space, there is usually only one station for scanning inspection on containers, which greatly limits the efficiency of scanning inspection, resulting in a large accumulation of containers.

It should be noted that the information disclosed in the background section of the present disclosure is only intended to enhance understanding of the general background of the present disclosure, and should not be considered as an admission or any form of implication that the information constitutes related technology well known to those skilled in the art. <CIT> discloses a crane apparatus installed on a foundation situated in water, comprising: a crane movable along the foundation for unloading containers from a vessel docked along the foundation and placing the containers on a deck of the crane and for transferring the containers from the deck to another location; and a container security scanning system for scanning the containers while the containers are on the deck to determine the presence of radioactive material in the containers. <CIT> discloses an unloading and loading crane with an arrow for loading the ship from the surface of the berth or unloading from the ship to the surface of the quay using a gripper attached to an arrow pivotally connected to the lever by means of a pivot hinge.

The technical solutions in the embodiments will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, and not all the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present disclosure.

In description of the present disclosure, it should be understood that orientation or position relations denoted by the terms "center", "transverse", "longitudinal", "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are orientation or position relations illustrated based on the drawings, are merely for the convenience of describing the present disclosure and simplifying description, instead of indicating or implying the denoted devices or elements must have specific orientations or be constructed and operated in specific orientations, and thus the terms cannot be understood as limiting the protection scope of the present disclosure.

Referring to <FIG> and <FIG>, in an illustrative embodiment of a container inspection system provided by the present disclosure, the container inspection system includes a quay crane <NUM> and an inspection device <NUM>, wherein the quay crane <NUM> includes a first hoisting component <NUM> and an inspection platform <NUM> provided with a plurality of stations, the first hoisting component <NUM> being configured to hoist a container <NUM> and transport the container <NUM> to at least one of the plurality of stations; and the inspection device <NUM> is disposed on the inspection platform <NUM> and configured to move relative to the container <NUM> on each of the plurality of stations, to perform scanning inspection on the container <NUM> on each of the plurality of stations, respectively.

The inspection device <NUM> is disposed on the inspection platform <NUM>, and thus may move with the movement of the quay crane <NUM>; at the same time, the inspection device <NUM> may also move on the inspection platform <NUM> relative to the container <NUM> on the station to perform scanning inspection on the container <NUM>.

In the above-mentioned illustrative embodiment, the inspection device <NUM> may move relative to the container <NUM> on each station, respectively, to perform scanning inspection on the container <NUM> on each station, so that the inspection position of the container inspection system may be more flexible. The inspection device <NUM> is not limited to scanning inspection at a specific station. After finishing scanning inspection on the container <NUM> on one of the stations, the inspection device <NUM> may turn to another station and perform scanning inspection on the container <NUM> on the another station, thus being beneficial to improving the efficiency of scanning inspection.

Furthermore, in the above-mentioned illustrative embodiment, by arranging the inspection device <NUM> on the inspection platform <NUM> of the quay crane <NUM>, a floor area occupied by the inspection device <NUM> may be reduced, and there is no need to reserve a special inspection location for the inspection device <NUM> in an area outside the quay crane, so that the overall layout of the port is more reasonable; and arranging the inspection device <NUM> on the inspection platform <NUM> of the quay crane <NUM> may also achieve the scanning inspection during the process of unloading the container <NUM> from a ship or during the process of loading the container <NUM> from the ground to a ship, to avoid in-yard inspection, and the process of transferring the container <NUM> to an AGV trolley and transporting by the AGV trolley the container <NUM> to an inspection location is omitted, thereby greatly reducing loading, unloading and scanning inspection time of the container <NUM>, shortening the total circulation time of the container <NUM> at the port, and improving the circulation efficiency; this may also prevent dangerous prohibited articles from entering a yard, and improve the safety.

In the above-mentioned illustrative embodiment, during the scanning inspection, the container <NUM> keeps stationary, and the inspection device <NUM> moves relative to the container <NUM>. Optionally, the container inspection system further includes a drive mechanism, which is configured to drive the inspection device <NUM> to move relative to the container <NUM>.

Optionally, guide rails are provided on two sides of each station, and the inspection device <NUM> moves along the guide rails to ensure the accuracy of the movement route of the inspection device <NUM> and improve the accuracy of scanning inspection.

Further, the container inspection system further includes a switching mechanism, which is configured to switch the inspection device <NUM> among the plurality of stations.

By providing the switching mechanism, the inspection device <NUM> may quickly switch among the plurality of stations, and from an attitude capable of scanning inspecting on the container <NUM> on one station to an attitude capable of scanning inspection on the container <NUM> on another station, thereby improving the degree of automation of the container inspection system; moreover, after finishing scanning inspection on the container <NUM> on one station, the inspection device <NUM> may quickly switch into a state of scanning inspection on the container <NUM> on another station, instead of that after scanning inspection on the container on an inspection station is finished, it also needs to transfer the container from the inspection station to a temporary storage station, and wait for the next container to arrive at the inspection station so as to start scanning inspection on the next container like in the related art, thus greatly shortening the waiting time for the inspection device <NUM> to perform scanning inspection on the next container, and improving the scanning inspection efficiency.

The switching mechanism includes a rotary switching mechanism, which is connected with the inspection device <NUM>, for rotating at least part of the inspection device <NUM>, so that after finishing scanning inspection on the container <NUM> on one of the plurality of stations, the inspection device <NUM> can perform scanning inspection on the container <NUM> on another of the plurality of stations.

The rotary switching mechanism is simple in movement form and flexible in switching, which is beneficial to shortening the switching time and improving the efficiency of scanning inspection. The switch mechanism being configured to be rotary also enables the arrangement of the plurality of stations to be more convenient.

Optionally, the plurality of stations include a first station <NUM> and a second station <NUM>, wherein the first station <NUM> is arranged on a side of a long edge of the second station <NUM>, and a long edge of the first station <NUM> and the long edge of the second station <NUM> are parallel to each other; and the switching mechanism is configured to rotate at least part of the inspection device <NUM> by <NUM> degrees. As shown in <FIG>, after finishing scanning inspection on the container <NUM> on the first station <NUM>, the inspection device <NUM> rotates <NUM> degrees and thereby can perform scanning inspection on the container <NUM> on the second station <NUM>.

The area ranges of the first station <NUM> and the second station <NUM> are roughly similar to the shape of the container <NUM>. Generally speaking, the container <NUM> is in the shape of a cuboid. The long edge of the first station <NUM> and the long edge of the second station <NUM> described above are parallel to a length direction of the container <NUM> (as a first direction).

Optionally, the plurality of stations may also include three stations, which are evenly arranged around the circumference. After finishing scanning inspection on the container <NUM> on one station, the inspection device <NUM> may rotate <NUM> degrees to switch to scanning inspection on the container <NUM> on another station adjacent thereto.

Of course, in the case where the plurality stations include four or more stations, the inspection device <NUM> may also switch to scanning inspection on another container <NUM> by rotating an appropriate angle, which is not detailed here.

In the above-mentioned various embodiments, the inspection device <NUM> optionally, but not limited to, moves in the length direction of the container <NUM>.

There may be multiple options for the specific structure of the inspection device <NUM>, so long as switching of the inspection device <NUM> between different stations can be achieved by the switching mechanism.

Optionally, the inspection device <NUM> includes a cabin <NUM>, a ray source <NUM> and an L-shaped arm installed with a detector, the ray source <NUM> being disposed in the cabin <NUM> and rotatable relative to the inspection platform <NUM>, and the L-shaped arm being mounted on the cabin <NUM> and rotatable relative to the inspection platform <NUM>.

Specifically, the inspection device <NUM> includes a rotation drive mechanism, which is configured to drive the ray source <NUM> and/or the L-shaped arm to rotate relative to the cabin <NUM>.

As shown in <FIG>, the top of the cabin <NUM> is provided with a slewing bearing <NUM>, wherein an outer ring of the slewing bearing <NUM> is connected with the cabin <NUM>, an inner ring of the slewing bearing <NUM> is connected with a horizontally arranged horizonal arm <NUM> of the L-shaped arm, and a vertically arranged vertical arm <NUM> is connected with the horizonal arm <NUM>. Rotation of the inner ring relative to the outer ring of the slewing bearing <NUM> may cause the L-shaped arm to rotate relative to the cabin <NUM>, to achieve switching of the inspection device <NUM> between different stations.

The slewing bearing <NUM> may be driven into rotation by a power device such as a hydraulic motor, a friction wheels, or a brake.

Correspondingly, a rotation mechanism may be provided between the ray source <NUM> and the cabin <NUM>, so that the ray source <NUM> can also rotate relative to the cabin <NUM>. This will not be detailed here.

In addition to the manner that the cabin <NUM> is fixed relative to the inspection platform <NUM>, and the ray source <NUM> and the L-shaped arm rotate relative to the inspection platform <NUM>, the switching of the inspection device <NUM> between different stations may also be achieved in such a manner that the cabin <NUM> rotates relative to the inspection platform <NUM> to cause the ray source <NUM> and the L-shaped arm to rotate. The manner that the cabin <NUM> is fixed relative to the inspection platform <NUM> and the ray source <NUM> and the L-shaped arm rotate relative to the inspection platform <NUM> is not limited by the shape of the cabin <NUM>, and does not involve an increase in the spacing width between two stations due to a reserved space for rotation of the cabin <NUM>.

In an example not forming part of the claimed invention, the plurality of stations include a first station <NUM> and a second station <NUM>, wherein the first station <NUM> is arranged on a side of a short edge of the second station <NUM>, and a short edge of the first station <NUM> and the short edge of the second station <NUM> are parallel to each other; and the switching mechanism includes a linear switching mechanism, which is connected with the inspection device <NUM>, for enabling the inspection device <NUM> to continue to move along a long edge of the second station <NUM> after finishing scanning inspection on the container <NUM> located on the first station <NUM>, to perform scanning inspection on the container <NUM> located on the second station <NUM>.

The area ranges of the first station <NUM> and the second station <NUM> are roughly similar to the shape of the container <NUM>. Generally speaking, the container <NUM> is in the shape of a cuboid. The short edge of the first station <NUM> and the short edge of the second station <NUM> described above are parallel to a width direction of the container <NUM> (as a second direction).

The linear switching mechanism may be understood as a mechanism that causes the inspection device <NUM> to move linearly. In the case, not forming part of the claimed invention, where the first station <NUM> and the second station <NUM> are arranged in the above-mentioned manner, the linear switching mechanism may cause the inspection device <NUM> to move along the length direction of the container <NUM> on the first station <NUM>, and after finishing scanning inspection on the container <NUM>, continues to move along the length direction of the container <NUM> on the second station <NUM> to perform scanning inspection on the container <NUM> on the second station <NUM>.

Specifically, the linear switching mechanism and the drive mechanism that drives the inspection device <NUM> to move may be a same mechanism. Compared with a drive mechanism in a container inspection system performing scanning inspection only at an inspection station in the related art, the drive mechanism in the embodiment drives the inspection device <NUM> to move along a same direction for longer time.

In the above-mentioned various embodiments, the first hoisting component <NUM> is further configured to hoist the container <NUM> on which scanning inspection is completed from the station where the container is located and transport the container <NUM> to a container transport equipment, so as to transport the container <NUM> to a target location by the container transport equipment.

As to the above-mentioned target location, in the case where the container is unloaded from a cargo carrying equipment such as a ship, the target location may be a warehouse for storing containers on the ground of a yard of the port, or may also be a freight truck loaded with containers, etc.; and in the case where the container is loaded to a cargo carrying equipment such as a ship, the target location may be a storage bin for storing containers on the cargo carrying equipment such as a ship.

In the case where the container is unloaded from a cargo carrying equipment such as a ship, the above-mentioned container transport equipment may be an AGV trolley, a container transport truck or the like. In the case where the container is loaded to a cargo carrying equipment such as a ship, the above-mentioned container moving equipment may be an equipment, disposed on the cargo carrying equipment such as a ship, for placing containers to corresponding storage bins.

In other embodiments, the quay crane <NUM> further includes a second hoisting component <NUM> for hoisting the container <NUM> on which scanning inspection is completed from the station where the container is located and transporting the container <NUM> to a container transport equipment. That is, the first hoisting component <NUM> is configured to hoist the container <NUM> and transport the container <NUM> to at least one of the plurality of stations, and the second hoisting component <NUM> is configured to hoist the container <NUM> on which scanning inspection is completed from the station where the container is located and transport the container <NUM> to a container transport equipment. Thus, their respective responsibilities are clearer to facilitate control.

Optionally, the set height of the second hoisting component <NUM> is lower than that of the first hoisting component <NUM> to avoid interference between the two hoisting components on travel routes, and also shorten the path for hoisting and moving away the container <NUM> and improve the circulation efficiency.

Optionally, the container inspection system further includes a guide mechanism disposed on the inspection platform <NUM>, for guiding the container <NUM> to fall in place on at least one of the plurality of stations. By providing the guide mechanism, the container <NUM> may fall accurately; it may also limit the container <NUM> to prevent the container <NUM> from deviating from the station disposed on the inspection platform <NUM>, and ensure the container <NUM> may be accurately hoisted every time after the first hoisting component <NUM> or the second hoisting component <NUM> falls, thereby reducing the alignment time and improving the circulation efficiency.

As shown in <FIG>, the guide mechanism includes a plurality of guide pillars having conic tops and arranged along edges of at least one of the plurality of stations, such that the container <NUM> may be guided and positioned by the guide pillars. The tops of the guide pillars are cone-shaped, so that the container <NUM> may be better guided to fall quickly and accurately.

Optionally, the guide mechanism is liftable relative to the inspection platform <NUM>. Thus, when the container <NUM> falls, the guide mechanism may be raised to guide the container <NUM>; after the container <NUM> falls in place, the and guide mechanism may be dropped to prevent the guide mechanism from influencing the movement of the inspection device <NUM>; in addition, when the inspection device <NUM> switches between different stations, the and guide mechanism is dropped so that the guide mechanism may be prevented from interfering with the switching of the inspection device <NUM>.

Optionally, the inspection device <NUM> includes a cabin <NUM>, a ray source <NUM> and an L-shaped arm installed with a detector, the ray source <NUM> being disposed in the cabin <NUM>, and the L-shaped arm being mounted on the cabin <NUM>; and the guide mechanism includes a plurality of first guide pillars <NUM> and a plurality of second guide pillars <NUM>, wherein the first guide pillars <NUM> are disposed on a side of the plurality of stations close to the cabin <NUM>, the plurality of first guide pillars <NUM> being non-liftable; and the second guide pillars <NUM> are disposed on a side of the plurality of stations away from the cabin <NUM>, the plurality of second guide pillars <NUM> being liftable. This arrangement may simplify the control as much as possible and improve the operation efficiency while ensuring the normal movement and switching of the inspection device <NUM>.

Based on the above-mentioned container inspection system, the present disclosure further proposes a port facility, which includes the above-mentioned container inspection system. The positive technical effects of the container inspection system in the various embodiments described above are also applicable to the port facility and are not repeated here.

Further, the container inspection method further includes:
hoisting the container <NUM> on which scanning inspection is completed from the station where the container is located and transporting the container <NUM> to a container transport equipment.

Optionally, before driving the inspection device <NUM> to move, the method may further include: detecting whether the container <NUM> is in place; if yes, executing the step of driving the inspection device <NUM> to move; and if not, performing detection again until detecting that the container <NUM> is in place.

A working process of an embodiment of the container inspection system, the port facility, and the container inspection method of the present disclosure will be described below in conjunction with <FIG>:.

As shown in <FIG> and <FIG>, in an embodiment of the container inspection system provided by the present disclosure, the container inspection system includes a quay crane <NUM>, and the quay crane <NUM> is provided with a first hoisting component <NUM>. The first hoisting component <NUM> hoists the container <NUM> from a container transport equipment such as a ship and places the container <NUM> onto an inspection platform <NUM> disposed on the quay crane <NUM>.

The inspection platform <NUM> is provided with a first station <NUM> and a second station <NUM>, the sizes of the first station <NUM> and the second station <NUM> being substantially same as the size of the container <NUM>. Generally, the container <NUM> is in the shape of a cuboid. In this embodiment, the first station <NUM> is arranged on a side of a long edge of the second station <NUM>, and a long edge of the first station <NUM> and the long edge of the second station <NUM> are parallel to each other; and a line connecting the center of the first station <NUM> and the center of the second station <NUM>, and the long edge of the first station <NUM> are parallel to each other.

The inspection device <NUM> includes a cabin <NUM>, and a ray source <NUM> disposed in the cabin <NUM>. The top of the cabin <NUM> is provided with a slewing bearing <NUM>, wherein an outer ring of the slewing bearing <NUM> is connected with the cabin <NUM>, and an inner ring of the slewing bearing <NUM> is connected with an L-shaped arm. The L-shaped arm is installed with a detector, and the L-shaped arm includes a horizontally arranged horizonal arm <NUM> and a vertically arranged vertical arm <NUM>. The cabin <NUM> is arranged between the first station <NUM> and the second station <NUM>, and the L-shaped arm spans across the stations on the inspection platform <NUM>.

A plurality of first guide pillars <NUM> are disposed on a side of the first station <NUM> away from the cabin <NUM> and on a side of the second station <NUM> away from the cabin <NUM>, with a distance formed between every two adjacent first guide pillars <NUM>, the first guide pillars <NUM> being liftable; and a plurality of second guide pillars <NUM> are disposed on a side of the first station <NUM> close to the cabin <NUM> and on a side of the second station <NUM> close to the cabin <NUM>, with a distance formed between every two adjacent second guide pillars <NUM>, the second guide pillars <NUM> being non-liftable.

In another embodiment, as shown in <FIG>, the quay crane <NUM> is further provided with a second hoisting component <NUM>. By means of the second hoisting component <NUM>, the container <NUM> on which scanning inspection is completed on the first station <NUM> or the second station <NUM> may be hoisted and transported to a container transport equipment such as an AGV trolley or a container transport truck at a port, and the container is transported to a target location by the container transport equipment.

Initially, supposing the first station <NUM> and the second station <NUM> are both empty, a container <NUM> is hoisted and transported by the first hoisting component <NUM> from a ship to the first station <NUM>, and after the container <NUM> is detected to fall in place, the inspection device <NUM> is started and moves relative to the first station <NUM>, to perform scanning inspection on the container <NUM> on the first station <NUM>; during the scanning inspection on the container <NUM> on the first station <NUM>, the first hoisting component <NUM> may hoist a second container <NUM> from the ship and transport the second container <NUM> to the second station <NUM>, and the inspection device <NUM> rotates <NUM> degrees after finishing scanning inspection on the container <NUM> on the first station <NUM>, and the vertical arm <NUM> rotates from the left side of the first station <NUM> to the right side of the second station <NUM>, and the inspection device <NUM> may return to an initial end and then move relative to the second station <NUM>, and perform scanning inspection on the container <NUM> on the second station <NUM> during the movement, or the inspection device <NUM> may not return to the initial end first, but performs scanning inspection on the container <NUM> on the second station <NUM> during returning to the initial end.

During the scanning inspection on the container <NUM> on the second station <NUM>, the container <NUM> on which scanning inspection is completed on the first station <NUM> may be hoisted and transported by the first hoisting component <NUM> or the second hoisting component <NUM> to an AGV trolley (or container transport truck) on the ground of the port, and then a third container <NUM> is hoisted and transported by the first hoisting component <NUM> from a ship to the first station <NUM>, so that after finishing scanning inspection on the container <NUM> on the second station <NUM>, the inspection device <NUM> may continue, by switching, to perform scanning inspection on the third container <NUM> on the first station <NUM>. The process proceeds in this way to accomplish continuous scanning inspection on multiple containers <NUM>.

Before the container <NUM> is hoisted and transported to the first station <NUM> or the second station <NUM>, the first guide pillars <NUM> on the left side of the first station <NUM> and on the right side of the second station <NUM> rise to guide the falling process of the container <NUM>; after the container <NUM> falls in place, the first guide pillars <NUM> fall to prevent the first guide pillars <NUM> from influencing the movement of the inspection device <NUM>; moreover, when the L-shaped arm of the inspection device <NUM> rotates, the first guide pillars <NUM> also need to be in a fallen state, to avoid collision with the first guide pillars <NUM> during rotation the L-shaped arm.
