Description

Technical Field

[0001] The present application relates to the field of wind power construction, and in particular to a single-blade guying system for the transformation of a cargo hook on a wind power installation vessel. Background Art

[0002] Due to the rich wind energy resources in the marine areas of our country, with the development of marine resources and the application of larger-capacity units, most coastal areas in our country have gradually become important sources of energy. Offshore wind turbines are wind turbines that use offshore wind energy resources for power generation, and mainly consist of a tower for supporting the generator set, a generator, blades, a hub, a converter, and a grid connection controller, etc. Since the blades of wind turbines are light in weight, long in length, and require the largest lifting height, they are one of the key points in the installation and construction control of wind turbines.

[0003] When installing the blades in a wind turbine, it is usually carried out by hoisting. The structure for hoisting the blades usually includes a suspension base, a hoisting cable, and a hoisting buckle. When hoisting the blades, they are connected to the blades through the hoisting buckle, and then the hoisting of the blades is achieved by driving the vertical movement of the hoisting cable. To ensure the stability of the blades during the hoisting process, multiple sets of hoisting buckles and hoisting cables are usually used to hoist the blades.

[0004] Regarding the above-mentioned existing technology, due to the long length of the blades, the cooperation of multiple sets of hoisting buckles and hoisting cables is not convenient for ensuring the stability of the overall hoisting process of the blades. During the hoisting process of the blades, the position of the blades is likely to shift due to the influence of wind, which is not convenient for quickly and stably lifting the blades to the required position. Summary of the Utility Model

[0005] In order to make it less likely for the position of the blades to shift due to the influence of wind during the hoisting process and to facilitate quickly and stably lifting the blades to the required position, the present application provides a single-blade guying system for the transformation of a cargo hook on a wind power installation vessel.

[0006] The single-blade guying system for the transformation of a cargo hook on a wind power installation vessel provided by the present application adopts the following technical solutions:

[0007] A single-blade guying system for the transformation of a cargo hook on a wind power installation vessel includes a hoisting base, and also includes a guying mechanism. The hoisting base includes a base and a boom installed on the top of the base. The guying mechanism includes a mounting seat, a mounting lifting assembly, guying ropes, a guying rope winding assembly, and a connecting head. The mounting lifting assembly is installed on the boom and is used to drive the mounting seat to move in the vertical direction. One end of the guying rope is installed on the mounting seat. The guying rope winding assembly is arranged on the base and is used to wind the guying rope. The connecting head is slidably fitted on the guying rope and is used to connect with the hoisting component.

[0008] By adopting the above technical solution, during the hoisting process of the hoisting component, i.e., the blade of the wind turbine, after connecting the hoisting cable to the blade, the hoisting component, i.e., the blade, is connected through the connector. Subsequently, the guy rope is released by the guy rope winding and rolling component, and the mounting base is moved vertically to a suitable position through the installation lifting component. Then, the blade is hoisted through the hoisting cable. During the blade hoisting process, the connector moves vertically under the limiting action of the guy rope. The connector, through cooperation with the guy rope, plays a limiting role during the blade hoisting process, so that the position of the blade is not easily offset due to the influence of wind during the hoisting process, facilitating the quick and stable hoisting of the blade to the required position.

[0009] Optionally, a fixing ring is installed on the mounting base. One end of the guy rope close to the mounting base is fixedly installed with a fixing head. The fixing head is provided with a fixing groove. The fixing ring is inserted and matched with the fixing groove. The fixing head is fixed to the fixing ring through a fixing bolt passing through itself and the fixing ring.

[0010] By adopting the above technical solution, the setting of the fixing bolt makes the fixing operation between the guy rope and the fixing ring, i.e., the mounting base, convenient, fast and stable.

[0011] Optionally, an installation connecting rope is passed through the fixing ring. Both ends of the installation connecting rope are fixedly installed on the mounting base.

[0012] By adopting the above technical solution, the setting of the installation connecting rope enables micro position adjustment and angle adjustment between the fixing ring and the mounting base, facilitating adaptation to different installation or hoisting situations, with strong applicability.

[0013] Optionally, the connector includes a connecting seat, a connecting pulley and a connecting ring. The connecting pulley is rotatably installed on the connecting seat. The connecting pulley is in rolling cooperation with the guy rope. The connecting ring is fixedly fitted with the connecting seat through a bolt passing through itself and the connecting seat.

[0014] By adopting the above technical solution, the setting of the connecting pulley is beneficial to further reduce the friction force when the guy rope moves relative to the connector, facilitating the sliding of the connector along the guy rope. The setting of the connecting ring facilitates the quick connection with the hoisting component.

[0015] Optionally, two limiting plates are fixedly installed on the connecting pulley. The guy rope is located between the two limiting plates.

[0016] By adopting the above technical solution, the limiting plates play a limiting role in the movement of the connecting pulley along the guy rope, which is beneficial to fully ensure the stability of the connecting pulley during movement.

[0017] Optionally, the guy wire winding assembly includes a winding frame, a winding roller and a winding motor. The winding frame is fixedly installed on the base, the winding roller is rotatably installed on the winding frame, one end of the guy wire is fixedly installed on the winding roller, and the winding motor is installed on the winding frame and used to drive the winding roller to rotate.

[0018] By adopting the above technical solution, the winding motor drives the winding roller to rotate, and the winding and unwinding of the guy wire can be quickly realized. Moreover, during the winding and unwinding process of the guy wire, the tension force on the connector can be adjusted synchronously, which is convenient for adaptation according to different hoisting situations and is beneficial to further enhancing the applicability.

[0019] Optionally, the installation lifting assembly includes a top lifting frame, a top lifting roller, a top lifting rope and a top lifting motor. The top lifting frame is fixedly installed on the boom, the top lifting roller is rotatably installed on the top lifting frame, one end of the top lifting rope is fixedly installed on the top lifting roller, and the other end is fixedly installed on the mounting seat. The top lifting motor is installed on the top lifting frame and used to drive the top lifting roller to rotate.

[0020] By adopting the above technical solution, the top lifting motor drives the top lifting roller to rotate, so that the top lifting rope can drive the mounting seat to move up and down in the vertical direction, making the vertical lifting movement of the mounting seat convenient and fast.

[0021] Optionally, the installation lifting assembly further includes a bottom lifting frame, a bottom lifting roller, a bottom lifting rope and a bottom lifting motor. The bottom lifting frame is fixedly installed on the boom, the bottom lifting roller is rotatably installed on the bottom lifting frame, one end of the bottom lifting rope is fixedly installed on the bottom lifting roller, and the other end is fixedly installed on the mounting seat. The bottom lifting motor is installed on the bottom lifting frame and used to drive the bottom lifting roller to rotate.

[0022] By adopting the above technical solution, during the process of the top lifting rope driving the mounting seat to move up and down in the vertical direction, the stable limit of the mounting seat during the vertical movement can be conveniently realized by driving the winding and unwinding of the bottom lifting rope by the bottom lifting motor, thereby further ensuring the stability of the mounting seat during the vertical movement.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. During the blade hoisting process, the connector moves in the vertical direction under the limiting action of the guy wire. The connector, through cooperation with the guy wire, plays a limiting role during the blade hoisting process, so that the blade is not likely to deviate from its position due to the influence of wind during the hoisting process, facilitating the quick and stable hoisting of the blade to the required position.

[0025] 2. The installation of the connecting rope enables fine position adjustment and angle adjustment between the fixing ring and the mounting base, facilitating adaptation to different installation or hoisting situations, with strong applicability.

[0026] 3. The setting of the connecting pulley helps to further reduce the friction when the guy rope and the connector move relative to each other, facilitating the sliding of the connector along the guy rope. The setting of the connecting ring facilitates the quick connection with the hoisting component. Description of the Drawings

[0038] Refer to Figure 2 and Figure 5 , one end of the guy wire 4 is installed on the mounting base 3. Specifically, the mounting base 3 is provided with a fixing ring 14. The fixing ring 14 includes a U-shaped fixing part 141 and a sealing bolt 142. The sealing bolt 142 passes through the two end parts of the U-shaped fixing part 141 and realizes the sealing treatment of the end part of the U-shaped fixing part 141 through the cooperation of nuts. The mounting base 3 is fixedly connected with a mounting connecting rope 15. The mounting connecting rope 15 passes through the fixing ring 14, that is, in the area surrounded by the U-shaped fixing part 141 and the sealing bolt 142. Both ends of the mounting connecting rope 15 are fixedly installed on the mounting base 3 to realize the connection between the fixing ring 14 and the mounting base 3.

[0039] Reference Figure 5 , at one end of the guy wire 4 close to the mounting base 3, a fixing head 16 is fixedly installed. The fixing head 16 is provided with a fixing groove 17. The U-shaped fixing portion 141 of the fixing ring 14 is inserted into the fixing groove 17.

[0040] Reference Figure 2 and Figure 4 , the guy wire winding assembly is arranged on the base 101 for winding the guy wire 4. Specifically, the guy wire winding assembly includes a winding frame 18, a winding roller 19 and a winding motor 20.

[0041] Reference Figure 2 and Figure 5 , the connecting head 5 is slidably fitted to the guy wire 4 and used for connecting with the hoisting component. Specifically, the connecting head 5 includes a connecting seat 501, a connecting pulley 502 and a connecting ring 503.

The connecting ring 503 is fixedly fitted to the connecting seat 501 by a bolt passing through itself and the connecting seat 。Specifically, the connecting ring 503 includes a U-shaped connecting portion 5031 and a connecting bolt 5032. The connecting bolt 5032 passes through both ends of the U-shaped connecting portion 5031 and realizes the sealing treatment of the ends of the U-shaped connecting portion 5031 through the cooperation of nuts, and the connecting bolt 5032 passes through the connecting seat 501 to realize the stable connection between the connecting seat 501 and the connecting ring 503. During the blade hoisting process, by passing the connecting rope or other fixing components fixed to the blade hoisting component through the U-shaped connecting portion 5031 and then sealing the ends of the U-shaped connecting portion 5031 by the connecting bolt 5032, the connecting head 5 can play a limiting role in the blade hoisting process, which is convenient and fast.

[0042] Reference Figure 5, during the hoisting process of the blade, the rolling between the connecting pulley 502 and the guy wire 4 is beneficial to reducing the friction force between the connector 5 and the guy wire 4, and further beneficial to ensuring the service life of the guy wire 4 and the connector 5. To further ensure the stability of the connecting pulley during the hoisting movement with the blade, a limiting plate 21 is fixedly installed at both ends of the connecting pulley 502, and the guy wire 4 is located between the two limiting plates 21 to play a role in limiting the position of the connecting pulley 502.

[0043] The implementation principle of the single-blade guy wire system for the transformation of the cargo stabilizing hook of a wind power installation ship in the embodiment of the present application is as follows: when it is necessary to hoist the blade of the hoisting component, that is, the wind turbine, first connect the hoisting cable 2 with the blade, then connect the hoisting component, that is, the blade, through the connector 5. Subsequently, the guy wire 4 is released by rotating the guy wire winding roller, and the mounting seat 3 is driven to move vertically to a suitable position by rotating the top lifting roller 7 and the bottom lifting roller 11 in the installation lifting assembly. After that, the blade can be hoisted through the hoisting cable 2. During the hoisting process of the blade, the connector 5 moves vertically under the limiting action of the guy wire 4. The connector 5 plays a role in limiting the blade during the hoisting process through the cooperation with the guy wire 4, so that the position of the blade is not easily offset due to the influence of wind force during the hoisting process, and it is convenient to quickly and stably hoist the blade to the required position.

[0044] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited hereby.
