[0021] According to the characteristics of offshore construction of wind turbine, the application proposes a cable wind support for installation on a boom. Specifically, two trusses symmetrically arranged relative to the boom are configured to have lengths of the truss rods being adjustable and being hinged in sequence. In this way, on the one hand, the interface size can be adjusted according to the actual boom structure to be suitable for different installation ship booms, and the first truss rod can be assembled and fixed to the boom structure by using the detachable connection parts at the two ends of the first truss rod, and after being detached, the first truss rod can be reused, thereby reducing the construction cost.

Detailed Implementation

[0041] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Without loss of generality, this embodiment is based on Figure 1The main body of the boom 10 shown in the figure is taken as the basis for description, and the cable wind support provided by the present solution is described in detail. For different installation ships, the structure size of the crane boom is different, and it should be understood that the specific implementation of the boom function is not the core of the present application, and does not constitute a substantial limitation on the cable wind support and the cable wind system claimed in the present application.

[0043] Please refer to Figure 1 , which is an assembly schematic diagram of the cable wind support according to the present embodiment.

[0044] As shown in the figure, the cable wind support provided by the present embodiment includes two trusses 20 symmetrically arranged relative to the boom 10, which are respectively detachably connected with the boom 10, and the length of the truss rod is adjustable.

[0045] In order to clearly describe the relative position and connection relationship between the truss rods, two projection planes are defined as the description reference in the present document, wherein the "first projection plane" is formed in the direction shown by arrow A in the figure, that is, the "first projection plane" is perpendicular to the length direction of the boom 10; the "second projection plane" is formed in the direction shown by arrow B in the figure, that is, the "second projection plane" is parallel to the length direction of the boom 10 and perpendicular to the direction of arrow B.

[0046] In the first projection plane perpendicular to the length direction of the boom, the truss rods of the two trusses 20 are arranged in a triangular shape, please refer to Figure 2 and Figure 3 together. Figure 2 is the A-view of Figure 1 , and Figure 3 is a schematic diagram of the overall structure of one side truss. The structures of the two side trusses 20 are the same, and one side truss 20 is described in detail here.

[0047] Combined with Figure 1 and Figure 2 , the first truss rod 1 is arranged close to the boom 10, and the two ends thereof are respectively provided with detachable connection parts adapted to the boom 10. In the present solution, the detachable connection parts adopt a hoop 4 structure to be adapted to the arm rod of the boom 10; during installation, the hoop 4 structure is buckled on the corresponding arm rod, and reliable fixation can be achieved by using a threaded fastener.

[0048] Of course, the detachable connection parts can also adopt other structural forms to achieve the function of being adapted to the arm rod structure and being convenient to disassemble and assemble, which are all within the scope claimed in the present application.

[0049] In this design, one end of the second truss member 2 and the third truss member 3 are hinged to both ends of the first truss member 1, and the other end of the second truss member 2 is hinged to the third truss member 3. The lengths of the first truss member 1, the second truss member 2, and the third truss member 3 are all adjustable. This allows for adjustment of the interface dimensions according to the actual boom structure. In other words, adjusting the length of the first truss member 1 ensures that the spacing of the clamps 4 meets the spacing requirements of the two boom members of the boom 10, making it suitable for booms on different installation vessels. After construction, the boom is disassembled and reused, effectively reducing construction costs.

[0050] Additionally, a guy rope guide is provided on the third truss member 3 to accommodate the guy ropes and generate a pulling force on the component to be installed or its special auxiliary clamps. For example, but not limited to, the lifting device 31 for the wind turbine blades, such as... Figure 10 In the usage configuration shown, the lifting device 31 is located on the side adjacent to the third truss rod 3 of the guy rope support. The guy rope guide can also be set on the second truss rod 2, which can also meet the need for adapting the guy rope. In comparison, setting the guy rope guide on the third truss rod 3 can avoid rope interference and facilitate a better guiding configuration.

[0051] In one implementation, the guy rope guide section can use a guide pulley 5 to smoothly guide the guy rope to form a pulling force according to a set direction.

[0052] Furthermore, based on the sequential hinged connection of each truss member, the length of the corresponding truss member can be adjusted according to the actual dimensions of the components and accessories to be installed. That is, based on the determined length of the first truss member 1, the dimensions of the second truss member 2 and the third truss member 3 can be further adjusted. This allows for adjustment of the working position of the guy rope guide pulley 5 on the truss, ensuring a safe distance m between the components and accessories to be installed and the boom. Figure 10 As shown, it can further accommodate the construction requirements of different products to be installed.

[0053] It should be noted that the first truss member 1, the second truss member 2, and the third truss member 3 are length-adjustable, while simultaneously meeting the reliability requirement of having a fixed working length under the adjusted length. The first truss member 1, the second truss member 2, and the third truss member 3 all include truss members. In fact, the truss members of the first truss member 1, the second truss member 2, and the third truss member 3 can be implemented using different structures, such as, but not limited to, using a nested, segmented approach. The following will illustrate this... Figure 5 and Figure 10 The first truss rod structure shown is illustrated as an example, wherein, Figure 4 for Figure 1 The diagram shows the assembly relationship of the first truss member 1. Figure 5 for Figure 4 CC section view.

[0054] The truss rod body has a first rod 11, a second rod 13 and a middle adjusting sleeve 12, and the first rod 11 and the second rod 13 are respectively inserted into the middle adjusting sleeve 12 from both ends, and the length of the corresponding truss rod body is adjusted by the insertion length of the first rod 11 and the second rod 13.

[0055] As an exemplary structure, in combination with Figure 4 and Figure 5 As shown in the drawings, a plurality of adjusting pin holes 14 are arranged on the middle adjusting sleeve 12 in an axial direction, and pin holes 15 are arranged on the first rod 11 and the second rod 13, and the pin holes 15 are arranged to be centered with the corresponding adjusting pin holes 14 according to the insertion length of the first rod 11 and the second rod 13, and are positioned and fixed by a pin 16 arranged in the pin hole 15 and the corresponding adjusting pin hole 14.

[0056] In theory, the number of pin holes 15 on the first rod 11 and the second rod 13, and the number and distribution interval of the adjusting pin holes 14 on the middle adjusting sleeve 12 are not limited, and can be selected 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 direction of the rope according to the angle adjustment requirements of the cable rope, it is within the scope claimed in the present application.

[0057] In order to improve the load stability of the truss structure, as shown in Figure 1 The first truss rod 1, the second truss rod 2 and the third truss rod 3 are arranged in two groups, and in the second projection plane parallel to the length direction of the boom 10, the first truss rods 1 in the two groups are arranged at intervals, and the other ends of the two second truss rods 2 and the two third truss rods 3 in the two groups are arranged at intersections, that is, the hoops 4 on the first truss rods 1 adapted to the arm rods of the boom 10 are arranged at intervals, and the side of the installation guide pulley 5 is collected at one place. In the force state of the guide pulley 5 at this position, each side truss 20 has good load stability.

[0058] The second truss rod 2 is located above the third truss rod 3; specifically, the second truss rod 2 includes a truss rod body 21 and a connecting rope group 22, that is, the connection area of the second truss rod 2 is composed of two parts of working length. In combination with Figure 3 As shown in the drawings, a winding member 23 for winding the connecting rope group 22 can be arranged on the truss rod body 21, and a hinge pulley group 6 is arranged at the other end of the third truss rod 3; the rope cable of the connecting rope group 22 is wound on the hinge pulley group 6, and the working length of the connecting rope group 22 is adjusted by driving the driving member to rotate the winding member 23. It should be noted that the hinge base relationship between the second truss rod 2 and the third truss rod 3 is realized by the winding method of the connecting rope group 22 and the hinge pulley group 6.

[0059] The driving component is preferably a servo motor 24, which can drive the winding component 23 to release or wind the rope according to the control command. The winding component 23 can release the rope to lengthen the working length of the connecting rope set 22, or wind the rope to shorten the working length of the connecting rope set 22.

[0060] Thus, the total length of the connecting area of the second truss rod 2 can be adjusted, and the working position of the cable wind rope guide pulley 5 relative to the boom 10 can be changed. In this way, the adjustment can be made according to the actual construction situation, for example, but not limited to, when the cable wind force changes suddenly, the servo motor 24 drives the winding component 23 to rotate, and based on the change of the working length of the connecting rope set 22, the working position of the guide pulley changes accordingly. Overall, the force acting on the cable wind support can be reduced.

[0061] It should be noted that the winding mode of the steel wire rope of the connecting rope set 22 on the winding component 23, and the specific configuration mode of the winding component 23 and the servo motor 24 can be selected according to different product design requirements. For example, but not limited to Figure 6 The assembly relationship between the connecting rope set and the winding drum is shown in the figure. That is, the winding component for realizing the winding and unwinding of the steel wire rope of the connecting rope set 22 can also be realized by other structures as long as it can meet the functional needs of adjusting the working length of the connecting rope set 22.

[0062] As shown in Figure 6 The winding component 23 can be arranged on the winding component support 231 and fixed on the truss rod body 21 of the second truss rod 2 through the winding component support 231, and the steel wire rope of the connecting rope set 22 is wound on the winding component 23 and connected to the articulated pulley set 6. The servo motor 24 can be arranged on the winding component 23 or the winding component support 231 to provide the rotating driving force of the winding component 23 and complete the unwinding operation of the winding component 23.

[0063] In order to make the cable wind angle have an adaptive adjustment function, the structure assembly arranged on the guide pulley 5 is further optimized. Please refer to Figure 7 The figure shows a structure diagram of a guide pulley, which can be universally wound.

[0064] The guide pulley 5 includes a pulley 51, a pulley support 52, a rotating shaft 53 and a support support 54. As shown in the figure, the pulley 51 is installed on the pulley support 52 through a bolt pair 55 and can rotate relative to the pulley support 52 around the bolt pair 55; the pulley support 52 is connected with the rotating shaft 53, the rotating shaft 53 is inserted into the opening of the support support 54, and the pulley support 52 can rotate relative to the support support 54 around the rotating shaft 53, so that the pulley 51 can rotate together with the pulley support 52. Please refer to Figure 8 The use state diagram is shown.

[0065] The pulley support 52 can further be provided with an out-rope baffle 56, which can be pivotally connected with the bolt pair 55 to rotate relative to the pulley support 52 with the adjustment of the out-rope angle. For details, please refer to Figure 9 The out-rope baffle 56 is internally provided with a nylon structure to ensure smooth in-out of the rope and avoid the phenomenon of disordered rope.

[0066] Please further refer to Figure 10 , which shows a schematic diagram of a use state of the adaptive boom cable wind system. In the use state shown in the figure, the wind turbine blade 30 is taken as the installation object, and the cable wind rope extending out of the guide pulley 5 on the truss 20 is used to achieve the pulling.

[0067] The adaptive boom cable wind system includes the cable wind support as described above, and two winches 40 for providing the pulling steel wire ropes 7. The two winches 40 are respectively arranged corresponding to the two trusses 20, and the pulling steel wire ropes 7 extending out of each winch 40 pass through the corresponding cable wind rope guide part, and the rope ends are respectively used to pull the spreaders 31.

[0068] It should be noted that the winches 40 can be independently configured. In the present scheme, the two winches 40 arranged on the crane boom 10 of the installation ship are preferably used as the cable wind ropes of the cable wind system to reasonably control the construction cost. As Figure 10 shown, the pulling steel wire ropes 7 of the winches 40 extend out, are reversed through the reversing pulley 8 arranged on the boom 10, extend along the truss 20 to the guide pulley 5 at the outer end of the truss 20, and pull the spreader 31 for installing the blade 30 through the guide pulley 5.

[0069] Further, in order to further avoid the sudden change in the cable wind force adjustment process, which causes the cable wind support to be in a relatively poor stress state. The present scheme further provides an automatic adjustment control mode, which specifically includes two tension sensors 50 and a controller 100.

[0070] As shown in Figure 10 , the two tension sensors 50 are respectively arranged on the two pulling steel wire ropes 7 to collect the pulling force of the corresponding pulling steel wire rope and transmit it to the controller 100. The controller is used to output a first control instruction to the driving component according to the pulling force, that is, output the first control instruction to the servo motor 24 to adjust the working length of the connecting rope set 22. The first control instruction is a control signal for adjusting the tightening and loosening of the rope, so that the servo motor 24 drives the winding component to rotate, and the closed-loop control of the working position adjustment of the cable wind rope guide part relative to the boom can be realized, the cable wind force is balanced, and the safety and reliability of the installation construction are further ensured.

[0071] As shown in Figure 2 and Figure 10As shown, the cable wind support further comprises a support oil cylinder 60, both ends of which are hingedly connected with the truss rod bodies of the second truss rod 2 and the third truss rod 3 respectively, so as to further improve the overall load bearing capacity of the cable wind support; meanwhile, according to the pulling force adopted by the corresponding pulling force sensor 50, the controller 100 is further configured to output a second control instruction to the control end of the support oil cylinder 60, so as to adjust the working length of the support oil cylinder 60 by controlling the conduction state of the hydraulic oil in the two cavities of the support oil cylinder 60, and cooperate with the adjustment of the working length of the connecting rope set 22, so that the second truss rod 2 is in a good stress state, and the load bearing stability is improved.

[0072] The following will be combined Figure 10 and Figure 11 to briefly describe the action mechanism of realizing the closed-loop control of the working position of the guide pulley 5. Among them, Figure 11 is another use state diagram of the adaptive boom cable wind system shown in Figure 10 .

[0073] As shown in Figure 10 , the pulling force of the pulling steel wire rope 7 in the extension direction collected by the pulling force sensor 50 is F, the component force of the pulling force F in the pulling direction is F1, and the angle between the extension direction of the pulling steel wire rope 7 and the pulling direction is a.

[0074] When the pulling force sensor 50 detects that the pulling force F is too large (for example, but not limited to, more than 5 tons), the servo motor 24 receives the first control instruction and starts to release the steel wire rope of the connecting rope set 22, the working length of the connecting rope set 22 becomes larger, that is, the distance between the truss rod body 21 and the hinged pulley set 6 is increased, so that the angle a between the extension direction of the pulling steel wire rope 7 and the pulling direction changes.

[0075] As shown in Figure 11 , it becomes angle b. On the basis of the same F, the component force in the pulling direction is F2, and since the angle a < b, F1 > F2. That is, by adjusting the above, the component force in the pulling direction can be reduced, and the stress of the cable wind support during construction is ensured.

[0076] In this process, the support oil cylinder 60 can synchronously adjust its support length in real time according to the angle change. Among them, the winch 40 does not need to act under normal circumstances, and can be used to release the pulling force F in the standby state. The "standby state" here includes the situation that the servo motor 24 is stuck, the hinged pulley set 6 cannot smoothly release the rope, and the support oil cylinder 60 cannot be pushed and pulled, etc.

[0077] As shown in Figure 10 , the distance between the lifting appliance 31 and the boom 10 structure is m, the distance between the two guide pulleys 5 is D, and the distance between the boom 10 structure arms is t. For different sizes of the boom 10 structure, the distance between the two guide pulleys 5 can be adjusted to match the size of the boom. Specifically, it can beFigure 11 The distance E shown matches the arm pole distance of the crane arm t1, or Figure 12 The distance F shown matches the arm pole distance of the crane arm t2, ensuring that the cable wind force is always within the set range.

[0078] Further, a damping device 70 is arranged on each of the two pulling steel wires 7, which can dissipate energy to provide buffering when the tension suddenly changes, avoiding the influence of the sudden tension of the spreader 31 on the pulling steel wire 7, further ensuring the uniform bearing of the cable wind force and ensuring the safety of the installation operation.

[0079] In addition, the adaptive crane arm cable wind system provided by the embodiment can further form an overall control strategy based on the current wind speed data to maximize the uniformity of the cable wind force.

[0080] In combination Figure 10 As shown, a wind measurement system can be arranged on the cable wind support for collecting wind data such as but not limited to wind speed and wind direction data signals, and transmitting the signals to the controller 100 for comprehensive judgment as basic parameters, and outputting corresponding control instructions to the corresponding side servo motor 24 and support oil cylinder 60. Please refer to Figure 13 The figure shows the control block diagram of the adaptive crane arm cable wind system according to the embodiment.

[0081] Corresponding to the wind measurement system 80, a wind-solar energy storage battery 90 can also be arranged to provide power for the wind measurement system 80 and can be used for the collection and feedback of the entire control loop signal. Here, wind energy and solar energy can be fully utilized for energy storage, which meets the design trend of clean energy utilization. In addition, the wind-solar energy storage battery 90 also includes an external charging interface, which can also be used when the stored power of wind energy and solar energy cannot meet the actual needs.
