With regard to the characteristics of offshore construction operations of a wind turbine, a guy cable bracket configured to be mounted on the boom is proposed in another approach in the present application. Specifically, two trusses arranged symmetrically with respect to the boom are configured such that the length of each truss rod is adjustable and the truss rods are articulated in sequence. In this way, on one hand, the size of a connecting port is adjustable based on the actual boom structure, so as to be suitable for booms of different installation ships. The truss rods are assembled and fixed to the boom structure by using the detachable connecting parts at two ends of the first truss rod, which can be reused after disassembly, thereby reducing the construction costs. On the other hand, in the first projection plane perpendicular to the length direction of the boom, the truss rods of each of the trusses are arranged in a triangular shape.

Compared with the conventional technology, the application of the solution has the following advantageous technical effects:

Firstly, the guy cable bracket provided by this solution has an adjustable connecting port, which is compatible with the boom suitable for different installation ships, and has good versatility. Furthermore, based on the adjustable structure of the truss in the solution, after being installed on the boom, the trusses can be adjusted in a wide range of angles according to actual construction requirements, thereby adjusting the guy cable tension force to an optimal state.

Secondly, in the preferred solution of the present application, the second truss rod located above the third truss rod is further optimized. The second truss rod includes the truss rod body and the connecting rope group. The connecting rope group is connected between the truss rod body of the second truss rod and the third truss rod, the total length of the second truss rod can be adjusted by adjusting the working length of the connecting rope group, thereby changing the operating position of the hawser guiding portion relative to the boom. In this way, adjustments can be performed according to the actual construction situation, for example, but not limited to, when the guy cable force changes suddenly, the driving component is controlled to drive the winding component to rotate. Based on the change in the working length of the connecting rope group, the operating position of the hawser guiding portion changes accordingly. On the whole, problems of affecting construction safety and reliability can be avoided by reducing the force acting on the guy cable bracket.

Thirdly, in the adaptive boom guy cable system according to the present application, the magnitude of the tension force is obtained in real time through the tension sensor provided on the traction steel wire rope, the first control instruction is outputted to adjust the working length of the connecting rope group, and the winding component is driven to rotate by the driving component.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In order to enable those skilled in the art to better understand the technical solutions of the present application, the present application is described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Without loss of generality, in this embodiment, a guy cable bracket which can provide an adaptable universal interface according to the present solution is described in detail on the basis of a main structure of boom segments10shown inFIG.1. Crane boom structures for different installation ships have different dimensions. It should be understood that the core conception of the present application does not lie in the specific implementation of the function of the boom, which does not constitute substantial limitations to a guy cable bracket and a guy cable system claimed in the present application.

With reference toFIG.1,FIG.1is a schematic assembly view of the guy cable bracket according to the present embodiment.

As shown in theFIG.1, the guy cable bracket according to the embodiment includes two trusses20arranged symmetrically with respect to the boom10. Each of the two trusses20is detachably connected to the boom10, and has a truss rod with an adjustable length.

In order to clearly describe the relative position and connection relationship between the truss rods, two projection planes are defined herein as a description benchmark. A first projection plane is formed in a direction indicated by arrow A in theFIG.1. That is, the first projection plane is perpendicular to a length direction of the boom10. A second projection surface is formed in the direction indicated by arrow B in theFIG.1. That is, the second projection surface is parallel to the length direction of the boom10and perpendicular to the direction of arrow B.

In the first projection plane perpendicular to the length direction of the boom, truss rods of each of the two trusses20are arranged in a triangular shape. Reference is made toFIGS.2and3together.FIG.2is a view taken along a direction A ofFIG.1, andFIG.3is a schematic view showing the overall structure of trusses at one side. The trusses20at both sides have the same structures, and the trusses20at one side are described in detail here.

As shown inFIGS.1and2, a first truss rod1is arranged close to the boom10, and each of two ends of the first truss rod1is provided with a detachable connecting part which is adaptable to the boom10. In this solution, the detachable connecting part is configured as a structure of a hold hoop4to adapt to an arm rod of the boom10. When being installed, the structure of the hold hoop4is fastened to the corresponding arm rod and can be reliably fixed by using a threaded fastener.

Of course, alternatively, the detachable connecting part can be implemented in other structural forms, as long as the functional requirements of being structurally adapted to the arm rod and easy to disassemble and assemble can be met, the structural forms fall within the scope of protection claimed by the present application.

One end of a second truss rod2is hinged with one end of the first truss rod1and one end of a third truss rod3is hinged with the other end of the first truss rod1, and the other end of the second truss rod2is hinged with the other end of the third truss rod3. The first truss rod1, the second truss rod2and the third truss rod3each is adjustable in length. In this way, the size of a connecting port can be adjusted according to the actual boom structure. In other words, the length of the first truss rod1is adjusted so that the distance between the hold hoops4meets the requirements for spacing between two arm rods of the boom10, so as to be applied in booms of different installation ships. After construction is completed, the hold hoops4can be disassembled and reused, which can effectively reduce the construction costs.

In addition, a hawser guiding portion5is provided on the third truss rod3for adapting a hawser7to form a force for pulling a component to be installed or a special auxiliary clamping device and other structures, for example, but not limited to, a lifting device31of the blade of the wind turbine. In the usage state shown inFIG.10, the lifting device31is located at one side, adjacent to the third truss rod3, of the guy cable bracket. The hawser guiding portion may be provided on the second truss rod2, which can also meet the needs of the function of adapting to the hawser. In comparison, the hawser guiding portion being provided on the third truss rod3can avoid the interference of reeving and help to form a better guide configuration relationship.

In one implementation, the hawser guiding portion may be configured as a guiding pulley5to smoothly guide the hawser7to form a tension force according to a set direction.

Furthermore, based on the connection manner of the truss rods being sequentially hinged, the length of the corresponding truss rod can be adjusted based on the actual size of a component to be installed and an auxiliary tool. That is to say, after the length of the first truss rod1is adjusted, the size of the second truss rod2and the third truss rod3can be further adjusted, thereby adjusting the operating position of the hawser guiding pulley5on the truss, so as to ensure a safe distance m between the component to be installed, the auxiliary tool, and the boom, as shown inFIG.10, which can further accommodate the construction requirements of different products to be installed.

It should be noted that the first truss rod1, the second truss rod2and the third truss rod3have the characteristics of adjustable length, and at the same time meet the reliability requirement of having a fixed working length under the adjusted length. The first truss rod1, the second truss rod2and the third truss rod3each includes a truss rod body. In fact, the truss rod bodies of the first truss rod1, the second truss rod2and the third truss rod3may be configured as different structures, for example, but not limited to, separate nesting of upper and lower segments. The first truss rod structure shown inFIGS.5and10is described hereinafter as an example.FIG.4is a schematic view showing assembly relationship of the first truss rod1as shown inFIG.1, andFIG.5is a cross-sectional view taken along a line C-C ofFIG.4.

The truss rod body has a first rod11, a second rod13and a middle adjustment sleeve12. The first rod11and the second rod13are inserted into the middle adjustment sleeve12from two ends, respectively. The length of the corresponding truss rod body is adjusted by adjusting insertion lengths of the first rod11and the second rod13.

As an exemplary structure, as shown inFIGS.4and5, multiple adjustment pin holes14spaced apart along an axial direction are formed in the middle adjustment sleeve12, and pin fixing holes15are formed in the first rod11and the second rod13and are configured to be aligned with the corresponding adjusting pin holes14based on the insertion lengths of the first rod11and the second rod15, and are fixed by positioning through pins16in the pin fixing holes15and the corresponding adjusting pin holes.

Theoretically, the number of the pin fixing holes15in the first rod11and the second rod13and the number and distribution interval of the adjusting pin holes14in the middle adjustment sleeve12are not limited, and can be determined according to the actual product design. It should be understood that as long as the length of the corresponding truss rod can be adjusted to match the extending direction of the hawser based on the angle adjustment requirements of the hawser, it is within the scope of protection claimed by the present application.

In order to improve the load-bearing stability of the truss structure, as shown inFIG.1, two groups of the first truss rod1, the second truss rod2and the third truss rod3are provided, and in a second projection plane parallel to the length direction of the boom10, the first truss rods1in the two groups are spaced apart, and the other end of the second truss rod2and the third truss rod3in each of the two groups are intersected. That is, the hold hoops4, adapted to the arm rods of the boom10, which is provided on the first truss rod1are spaced apart, and one side, where the guiding pulley5is mounted, of each of the two groups is gathered together. When the guiding pulley5at this position is stressed, the trusses20at each side have good load-bearing stability.

The second truss rod2is located above the third truss rod3. Specifically, the second truss rod2includes a truss rod body21and a connecting rope group22. That is, the connection area of the second truss rod2is composed of two parts of the working length. As shown inFIG.3, a winding component23for winding the connecting rope group22may be provided on the truss rod body21, and a hinged pulley system6is provided at the other end of the third truss rod3. The cable of the connecting rope group22is wound around the hinged pulley system6. The working length of the connecting rope group22is adjusted by the driving component24that drives the winding component23to rotate. It should be noted that the basic hinged relationship between the second truss rod2and the third truss rod3is realized by the winding manner of connecting rope group22and the hinged pulley system6.

The driving component is preferably a servo motor24, which can specifically drive the winding component23to release or retract the rope in response to a control instruction. The rope-releasing operation of the winding component23can lengthen the working length of the connecting rope group22, and the rope-retracting operation of the winding component23can shorten the working length of the connecting rope group22.

Thereby, the total length of the connectable area of the second truss rod2is adjusted, thereby changing the operating position of the hawser guiding pulley5relative to the boom10. In this way, adjustments can be made according to the actual construction situation, for example, but not limited to, when the guy cable force changes suddenly, the servo motor24is controlled to drive the winding component23to rotate. Based on the change in the working length of the connecting rope group22, the operating position of the guiding pulley changes accordingly. Overall, the force acting on the guy cable bracket can be reduced.

It should be noted that the winding manner of a steel wire rope of the connecting rope group22on the winding component23and the specific configuration of the winding component23and the servo motor24can be determined according to different product design requirements, for example, but not limited to, schematic view showing assembly relationship between the connecting rope group and a winding barrel as shown inFIG.6. That is, the winding component configured to realize the retracting and releasing of the steel wire rope of the connecting rope group22may be implemented in other structures, as long as it can meet the functional requirements of adjusting the working length of the connecting rope group22.

As shown inFIG.6, the winding component23may be arranged on a winding component bracket231, and is fixed on the truss rod body21of the second truss rod2through the winding component bracket231. The steel wire rope of the connecting rope group22is wound around the winding component23and wound around the hinged pulley system6. The servo motor24may be arranged on the winding component23or on the winding component bracket231to provide rotational driving force of the winding component23, so as to complete the rope-releasing operation of the winding component23.

In order to enable the guy cable angle to have an adaptive adjustment function, the structural assembly provided on the guiding pulley5is further optimized. Reference is made toFIG.7, which shows a schematic structural view of a guiding pulley for which a hawser is extendable in a universal direction.

The guiding pulley5includes a pulley51, a pulley bracket52, a rotating shaft53and a bracket support54. As shown inFIG.7, the pulley51is mounted on the pulley bracket52through a bolt pair55, and can rotate around the bolt pair55relative to the pulley bracket52. The pulley bracket52is connected to the rotating shaft53, and the rotating shaft53is inserted into an opening of the bracket support54. The pulley bracket52can rotate around the rotating shaft53relative to the bracket support54, so that the pulley51can rotate along with the pulley bracket52. Reference may be made to a schematic view of the usage state shown inFIG.8for details.

The pulley bracket52may be further provided with a rope extending baffle56. The rope extending baffle56may be pivoted with the bolt pair55to rotate relative to the pulley bracket52with the adjustment of the rope extending angle. Reference may be made to a schematic view of the usage state shown inFIG.9for details. Specifically, the rope extending baffle56is internally provided with a nylon structure inside to ensure smooth rope entry and exit and avoid rope tangles.

Further reference is made toFIG.10, which shows a schematic view showing a usage state of an adaptive boom guy cable system. In the usage state shown in theFIG.10, the blade30of the wind turbine is used as the installation object, and is pulled by the guy cable rope7that is wound around the guiding pulley5on the truss20and extends out.

The adaptive boom guy cable system includes the guy cable bracket as described above and two hoists40, each of which provide the traction steel wire rope7. The two hoists40are respectively arranged corresponding to the two trusses20, and the traction steel wire rope7extended by each of the two hoists40bypasses the corresponding hawser guiding portion5, and one end of the hawser is configured for pulling the lifting device31.

It should be noted that the hoists40may be configured independently. In this solution, it is preferable to use the two hoists40provided on the boom10of a crane of the installation ship as the hawser of the guy cable system to reasonably control the construction cost. As shown inFIG.10, after the traction steel wire rope7of the hoist40is extended, the direction of the traction steel wire rope7is changed through a direction-changing pulley8provided on the boom10, then the traction steel wire rope7extends along the truss20to the guiding pulley5at an outer end of the truss20, and passes through and extends from the guiding pulley5and pulls the lifting device31for installing the blade30.

Furthermore, in order to further avoid sudden changes in the adjustment process of the force acted on the guy cable, which otherwise causes the guy cable bracket to be in a relatively bad stress state, an automatic adjustment control method is further provided in this solution. The adaptive boom guy cable system specifically includes two tension sensors50and a controller100.

As shown inFIG.10, two tension sensors50are respectively provided on the two traction steel wire ropes7for collecting a tension force of the traction steel wire ropes and transmitting the tension force to the controller100. The controller is configured to output a first control instruction to the driving component based on the tension force, that is, to output the first control instruction to the servo motor24so as to adjust a working length of the connecting rope group22. The first control instruction is a control signal for adjusting tightening and releasing the rope. In this way, the servo motor24drives the winding component to rotate, thereby realizing closed-loop control of adjusting the operating position of the hawser guiding portion relative to the boom, ensuring the guy cable tension force to be balanced to further ensure the safety and reliability of installation and construction.

As shown inFIGS.2and10, the adaptive boom guy cable system further includes a support oil cylinder60. Two ends of the support oil cylinder60are respectively hinged with the truss rod bodies of the second truss rod2and the third truss rod3to further improve the overall load-bearing capacity of the guy cable bracket. In addition, based on the tension force adopted by the corresponding tension sensor50, the controller100is further configured to output a second control instruction to a control end of the support oil cylinder60, and adjust the working length of the support oil cylinder60by controlling a hydraulic oil conduction state in two chambers of the support oil cylinder60, which, in cooperation with the adjustment of the working length of the connecting rope group22, allows the second truss rod2to be in a good stress state and improves the load-bearing stability.

A mechanism for realizing closed-loop control of the operating position of the guiding pulley5is briefly described hereinafter with reference toFIGS.10and11.FIG.11is a schematic view showing another usage state of the adaptive boom guy cable system shown inFIG.10.

As shown inFIG.10, a tension force in the extending direction of the traction steel wire rope7collected by the tension sensor50is represented as F, and the tension force F has a component F1in the pulling direction. An included angle “a” is formed between the extending direction of the traction steel wire rope7and the pulling direction.

In response to detecting that the tension force F is much great (for example, but not limited to, more than 5 tons) by the tension sensor50, the servo motor24receives the first control instruction and starts to release the steel wire rope of the connecting rope group22, and the working length of the connecting rope group22becomes larger. That is, the distance between the truss rod body21and the hinged pulley system6becomes larger, and thus the angle “a” between the extending direction of the traction steel wire rope7and the pulling direction changes.

As shown inFIG.11, the included angle “a” becomes an included angle “b”. On the basis that F is the same, F has a component force F2in the pulling direction. Since the angle “a” is less than “b”, F1is greater than F2. In other words, with the above adjustments, the component force in the pulling direction can be reduced, so as to ensure that the guy cable bracket is too stressed during the construction process.

During this process, the support oil cylinder60can simultaneously adjust the support length in real time based on the angle changing. The hoist40does not need to move under normal circumstances and can be used to release the tension force F in the standby state. The “standby state” here includes situations where the servo motor24is stuck, the hinged pulley system6cannot release the rope smoothly, and the support oil cylinder60cannot perform a pushing or pulling operation.

As shown inFIG.10, the distance between the lifting device31and the structure of the boom10is set to m, the distance between the two guiding pulleys5is set to D, and the distance between the structural arms of the boom10is set to t. For different sizes of boom10structures, the size of the boom can be matched by adjusting the distance between the two guiding pulleys5. Specifically, the distance E shown inFIG.11can match the boom with the arm rod distance t1, or the distance F shown inFIG.12can match the boom with the arm rod distance t2, so as to ensure the guy cable force to be always within a set range.

Furthermore, damping devices70are respectively provided on the two traction steel wire ropes7. The damping devices70can consume energy to provide buffering in a case of the tension force being suddenly changed, thereby avoiding the influence of the sudden tension force of the lifting device31on the traction steel wire rope7, and further ensuring the uniform wind load of the guy cable force and ensuring the safety of the installation operation.

In addition, the adaptive boom guy cable system according to the present embodiment can further form an overall control strategy based on the current wind speed data to maximize the uniformity of the guy cable force.

As shown inFIG.10, a wind measurement system may be provided on the guy cable bracket to collect wind data, for example, but not limited to data signals such as a wind speed and a wind direction. The wind measurement system transmits the data signals to the controller100to be used as basic parameters for comprehensive judgment. The controller100outputs the corresponding control instructions to the servo motor24and the support oil cylinder60at the corresponding side. Reference is made toFIG.13, which shows a control block diagram of the adaptive boom guy cable system according to the present embodiment.

Correspondingly to the wind measurement system80, a wind and solar energy storage battery90may be further provided to provide power for the wind measurement system80and can be used for collection and feedback of signals in the entire control-loop. Here, wind energy and solar energy can be fully utilized for energy storage, which is in line with the design trend of clean energy utilization. In addition, the wind and solar energy storage battery90further includes an external charging interface. When the electric energy stored by wind energy and solar energy cannot meet actual needs, the external charging interface can also be used. It should be noted that the core conception of the present application does not lie in the wind and solar energy storage battery90and the specific functions of the wind and solar energy storage battery90, which can be implemented by those skilled in the art based on the conventional technology, and thus will not be repeated here.

The adaptive boom guy cable bracket structure according to the embodiment can match the installation of the crane booms of different installation ships, and can realize a wide range of angle adjustment to adjust the guy cable tension force to be optimal. The damping device and the wind measurement and power supply system are provided in this solution, which can ensure the problem of guy cable tension force and buffering. In addition, the installation of the connecting ports of different installation ships can be universal, thereby greatly reducing the manufacturing costs of the guy cable bracket.

The above descriptions are merely preferred embodiments of the present application. It should be noted that various improvements and modifications can be made by those skilled in the art without departing from the principles of the present application. These improvements and modifications should fall within the protection scope of the present application.
