DETAILED DESCRIPTION OF EMBODIMENTS

Specific embodiments of the present application will now be described in detail with reference to the figures. The embodiments described herein are only preferred embodiments according to the present application. Those skilled in the art can envision other modes capable of implementing the present application on the basis of the preferred embodiments, and said other modes also fall within the scope of the present application.

The cable laying device100as disclosed in the present application can reach the technical effects of applying mechanical devices to transport and lay cables as shown inFIG.1, thereby reducing labor cost during oil field operations as well as avoiding severe cable damage during manual cable hauling. Besides, the cable laying device100disclosed in the present application can be adapted to different laying conditions defined by different electrical equipment, thereby improving the efficiency during cable laying. Specifically, as shown inFIG.1, the cable laying device can lay the cables, in the way of mechanical driving, to a certain height, at a certain angle as well as in a certain length to a position which is most convenient for electrical equipment.

Referring toFIG.1andFIG.2, it can be seen that the cable laying device100comprises: a cable laying part having a base section11and a length adjustable extension section12; a turnover mechanism20and a positioning adjustment mechanism30. Specifically, the base section11and the extension section12are such connected with each other at their longitudinal ends that they are moveable relative to each other, and can accommodate, transport and lay cables. Specifically, depending on the application, the extension section can be provided at one or both longitudinal ends of the base section. In this case, the extension section12can be extended from the base section11according to the working environment of the electrical equipment. In order to further achieve the flexibility in use, the cable laying device100further comprises a positioning adjustment mechanism30including a rotating assembly31which can be connected to the base section11, i.e. at a position such as one longitudinal end or a certain longitudinal position of the base section11, so that the base section11or the cable laying part can rotate driven by the rotating assembly, thus the cable laying device can be applied at different installation positions of electrical equipment. The cable laying device100comprises a turnover mechanism20, wherein the turnover mechanism20connects the base section11with the extension section12, so that the extension section12can be driven to turn over in different angles from the base section11depending on the requirements, thereby realizing different heights and lengths of the whole cable laying part and hence different cable laying solutions.

It needs to be explained here that in the present application, the “longitudinal position” of the base section11refers to the position along the length direction of the base section11or the extension section12.

Optionally, in order to enable the cable laying device100to be better applicable to electrical equipment of different heights, the positioning adjustment mechanism30may also have a lifting unit32for adjusting the height of the cable laying part. Here, in order to avoid the interference with the rotating movement of the cable laying part, the rotating assembly31can be arranged at the lifting unit32and the lifting unit32is connected to the cable laying part or the base section11via the rotating assembly31. The rotating assembly31can drive the base section or the cable laying part to rotate around the lifting unit32.

To be specific, optionally, the rotating assembly31may be configured as a gear transmission assembly known in the prior art, wherein the gear transmission assembly may be driven by an external motor or other driving mechanism, and its output part may be configured to connect with and drive the base section11into rotating.

Optionally, as shown inFIG.3, the turnover mechanism20that drives the extension section12to perform turnover movement may comprise a turnover driving part21and a bar transmission assembly22driven by the turnover driving part21. Specifically, the bar transmission assembly22includes a first bar element221and a second bar element222, wherein one end of the first bar element221is connected to the base section11, and the other end is pivotally connected to the second bar element222, meanwhile, the other end of the second bar element222is connected to the extension section12, and the base section and the extension section are connected with each other via a pivot shaft13, so that the first bar element221, the second bar element222, the base section11and the extension section12can form a four-bar linkage mechanism. In this case, the turnover driving part21connects and drives the pivot shaft between the first bar element221and the second bar element222to perform linear reciprocating movement, so that the second bar element222drives the extension section12to perform turnover movement.

Alternatively, the turnover driving part21may also be connected to and drive the first bar element221which is connected with the base section11to reciprocatingly rotate, so as to enable the second bar element222to drive the extension section12for performing turnover movement.

Within the scope of the present application, optionally, the turnover driving part21may be configured to comprise a turnover driving hydraulic cylinder, wherein the piston211of which may be connected with the bar transmission assembly i.e. the pivot shaft between the first bar element221and the second bar element222or the first bar element221, so as to drive the bar transmission assembly22.

Within the scope of the present application, optionally, in order to achieve a more stable and balanced turnover movement, the turnover mechanism20may be arranged along the longitudinal direction of the pivot shaft13between the base section11and the extension section12, for example, may be arranged in pairs at longitudinal ends of the pivot shaft13.

Since that, during operation of the cable laying device100, the cable laying part is often held in a certain height in the form of an elongated load-bearing part, in order to stabilize the height of the elongated cable laying part, the cable laying device100disclosed in the present application may optionally further include a height-holding mechanism40, which may be arranged together with the lifting unit32of the positioning adjustment mechanism30and maintain the desired height of the cable laying part. Specifically, the height-holding mechanism40may be configured to connect to the positioning adjustment mechanism30at one end while connect to the base section11at the other end, specifically connect at a longitudinal position other than the installation position of the positioning adjustment mechanism30or the rotating assembly31of the base section11, and hold the height of the cable laying part. That is, the height-holding mechanism40may be arranged along the longitudinal tilted direction relative to the cable laying part.

In this case, optionally, the positioning adjustment mechanism30may be provided at one longitudinal end of the cable laying part or the base section11, while the height-holding mechanism40can support the cable laying part at another longitudinal position of the base section11, thereby improving the stability of the cable laying part. For example, it can be considered that the height-holding mechanism40may comprise a hydraulic cylinder, wherein a piston is connected with the base section11and supports the cable laying part through telescopic movement.

In order to more conveniently transport the cable laying device100, the cable laying device100can also comprise a carrying mechanism50. It can be considered that the carrying mechanism50includes a semi-trailer, a vehicle-mounted structure or a skid-mounted structure, on the chassis51of which the positioning adjustment mechanism30can be fixedly arranged.

In the case where there exists a carrying mechanism50or a semi-trailer, a vehicle-mounted structure or a skid-mounted structure, when the cable laying part is rotated 90 degrees or more relative to the carrying mechanism50, it is possible that the center of gravity of the entire cable laying device100deviates from the carrying mechanism50and moves toward the cable laying part. Therefore, in order to maintain the stability of the carrying mechanism50in the above operating conditions, the cable laying device100may optionally include a lifting leg assembly60, which comprises at least one lifting leg61that supports and stabilizes the carrying mechanism50via lifting motion or telescopic movement. The lifting legs may be connected at both lateral sides of the chassis51of the semi-trailer, vehicle-mounted structure or skid-mounted structure (as shown inFIG.1or2). Depending on the degree the cable laying part have rotated relative to the chassis51, the lifting leg is configured to be able to rotate into different angles relative to the chassis51, thereby achieving optimal supporting for the carrying mechanism50.

Furthermore, within the scope of the present application, the connection direction between the extension section12and the base section11is not limited. That is, at the longitudinal ends of the extension section12and the base section11, the extension section12may include an extension section connected to the longitudinal extension surface of the base section11or an extension section connected to the lateral side surface of the base section11. In other words, when the extension section12is connected at the longitudinal extension surface of the base section11, the extension section12can lie on the longitudinal extension surface of the base section11when it is not “extended” or “turned over”, while when the extension section12is connected at both lateral sides of the base section11, the extension section12can abut against the lateral sides of the base section11when it is not “extended” or “turned over”.

The cable laying device disclosed by the present application can conveniently and efficiently realize electricity supply to a plurality of electrical equipment. As shown inFIG.1, depending on the location of the electrical equipment and site restrictions, the cable laying device can enable the cable laying part or the base section as well as the extension section to rotate by a certain angle (e.g., 90 degrees inFIG.1) by means of the rotating assembly, and adjust the height of the cable laying part by using the lifting unit, so that the rotating position and height of the cable laying part can be more suitable for connecting the electrical equipment. In addition, according to the number of electrical equipment and the height of their connectors, the extension section of the cable laying part can correspondingly turn over a certain angle relative to the base section to form a certain inclination, so as to supply the electrical equipment with electricity. Therefore, the cable laying device disclosed by the present application can not only reach a high cable laying efficiency, but also reduce the abrasion of the cables through the cable carrying and protecting effects accomplished by the cable laying part.
