Description

Technical Field

[0001] This utility model belongs to the field of cable laying technology, and in particular relates to a guide pulley block for laying cables for wind turbine units. Background Technology

[0002] The guide pulley system used in the laying of wind turbine cables is a key auxiliary tool, mainly used to control the cable path, reduce frictional resistance, protect the conductor from damage, and improve construction efficiency and safety.

[0003] In traditional wind turbine cable laying, multiple cables are typically passed through pulleys, each with its own locking mechanism to secure them. However, since there are usually many cables laid, using a single pulley for guidance requires workers to individually fix numerous pulleys and operate the locking mechanisms on each pulley to secure the cables. This not only significantly increases the workload but also reduces work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a guide pulley assembly for laying cables in wind turbine units. By setting a guiding mechanism, specifically by rotating the locking nut on the moving plate counterclockwise, the spring will push the moving plate through its elastic force, increasing the space between the upper and lower guide pulleys, making it easier for workers to lay cables quickly. Furthermore, multiple guide pulleys on the rotating rod can lay multiple cables simultaneously. Rotating the locking nut clockwise will bring the upper and lower guide pulleys closer together and clamp the cables, allowing multiple cables to be fixed at the same time without requiring individual operation by workers. This significantly improves laying efficiency and solves the problem that workers need to fix a large number of pulleys individually and operate the locking structure on the pulleys to lock the cables, which not only greatly increases the labor force but also results in low work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a guide pulley system for laying cables of wind turbine generators, including two supports, and also includes: A guiding mechanism, located on top of the support, includes two rotating rods arranged vertically. Several guide pulleys are fixedly connected to the outer surface of each rotating rod. Support blocks are rotatably connected to both ends of the lower rotating rod, with their bottoms fixedly connected to the top of the support. A movable plate is rotatably connected to the outer side of the upper rotating rod. The movable plate has slots on both its front and back sides, and vertical rods are installed inside these slots. The bottoms of the vertical rods are fixedly connected to the top of the support, and a locking nut is threaded onto the outer surface of the vertical rod. A bending mechanism is disposed between two supports, and the bending mechanism is used to connect the two supports and adjust the angle; The cable is used to pass through the guide pulleys, and the guide pulleys and the rotating rod are integrally set and uniformly installed on the support.

[0006] Furthermore, the outer surface of the vertical rod is provided with threads, and a locking nut is connected to the threaded outer surface of the vertical rod. A spring is sleeved on the outer side of the vertical rod, and a rubber sleeve is sleeved on the outer side of the spring. The rubber sleeve is used to cover the spring, which can play a certain protective role and prevent workers from accidentally touching it and being squeezed. The spring is used to apply a pushing force to the moving plate, and the locking nut is located on the top of the moving plate.

[0007] Furthermore, the top of the spring is fixedly connected to the bottom of the movable plate, the bottom of the spring is fixedly connected to the top of the support, the top of the rubber sleeve is fixedly connected to the bottom of the movable plate, and the bottom of the rubber sleeve is fixedly connected to the top of the support; when the movable plate moves downward, it will compress the spring, and when the locking nut is loosened, the spring will push the movable plate with its elastic force.

[0008] Furthermore, the bending mechanism includes a fixing plate 1 and a fixing plate 3 fixedly connected to the right support, and a fixing plate 2 fixedly connected to the right side of the left support. The fixing plate 2 has a circular hole inside, and a rotating ring is fixedly connected to the bottom of the fixing plate 3. A square block is fixedly connected to the top of the fixing plate 2, and a threaded shaft is fixedly connected to the top of the square block. A locking nut 2 is threadedly connected to the outer surface of the threaded shaft. When the other support is rotated to a suitable angle, the locking nut 2 is first turned clockwise with a wrench to lock the fixing plate 1. At this time, the angle of the other support is fixed, which makes it convenient to fix the support to the wind turbine unit with screws later. The third fixing plate is located below the first fixing plate, and the second fixing plate is located below the third fixing plate.

[0009] Furthermore, the first fixing plate has an arc-shaped groove inside, the threaded shaft is set inside the arc-shaped groove, and the second locking nut is set on the top of the first fixing plate; the diameter of the threaded shaft is slightly smaller than the inner diameter of the arc-shaped groove, so that the first fixing plate can rotate smoothly.

[0010] Furthermore, the rotating ring is disposed inside the circular hole, and the rotating ring is rotatably connected to the second fixed plate via a bearing. A gap is left between the top of the square block and the bottom of the first fixed plate. The support is fixedly connected to the inner wall of the wind turbine by screws. The third fixed plate is used to connect the two supports to each other by cooperating with the second fixed plate via the rotating ring. When the other support is rotated and adjusted, the first fixed plate and the third fixed plate will rotate together, and the rotating ring will rotate within the circular hole, making the support adjustment more stable.

[0011] This utility model has the following beneficial effects: 1. This utility model, by setting a guiding mechanism, specifically by rotating the locking nut on the moving plate counterclockwise, will cause the spring to push the moving plate through its elastic force, increasing the space between the upper and lower guide pulleys, making it convenient for workers to quickly lay cables. In addition, the rotating rod is equipped with multiple guide pulleys, which can lay multiple cables at the same time. When the locking nut is rotated clockwise, the upper and lower guide pulleys move closer to each other and clamp the cables, which can fix multiple cables at the same time without the need for individual operation by workers, thus greatly improving the laying efficiency.

[0012] 2. This utility model incorporates a bending mechanism. Specifically, by rotating the second locking nut counterclockwise, the two supports are released from their fixation. Then, the other support is rotated and adjusted, causing the rotating ring to rotate within the circular hole, ensuring stable rotation adjustment of the support. Once the appropriate angle is reached, the second locking nut is rotated clockwise using a wrench, thus fixing the other support. This allows for the bending and guiding of the cable during laying, meeting different laying requirements and improving the aesthetics of the laid cable.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] Please see Figures 1-5 As shown, this utility model is a guide pulley system for laying cables of wind turbine generators, including two supports 1, and also includes: Guide mechanism 2 is located on top of support 1. Guide mechanism 2 includes two rotating rods 21, which are arranged vertically. Several guide pulleys 211 are fixedly connected to the outer surface of the rotating rods 21. Support blocks 22 are rotatably connected to both ends of the lower rotating rod 21. The bottom of the support blocks 22 is fixedly connected to the top of support 1. A movable plate 23 is rotatably connected to the outer side of the upper rotating rod 21. The movable plate 23 has slots 231 on both the front and back. A vertical rod 24 is installed inside the slot 231. The bottom of the vertical rod 24 is fixedly connected to the top of support 1. A locking nut 242 is threaded onto the outer surface of the vertical rod 24. When the locking nut 242 on the movable plate 23 is rotated counterclockwise, the spring 241... The movable plate 23 is pushed by the elastic force, increasing the space between the upper and lower guide pulleys 211, which facilitates the workers to lay cables quickly. The rotating rod 21 is equipped with multiple guide pulleys 211, which can lay multiple cables at the same time. When the locking nut 242 is turned clockwise, the upper and lower guide pulleys 211 move closer to each other and clamp the cables, which can fix multiple cables at the same time without the need for individual operation by the workers, greatly improving the laying efficiency. There is also a bending mechanism 3, which is set between two supports 1. The bending mechanism 3 is used to connect the two supports 1 and adjust the angle. The cable is used to pass through the guide pulleys 211. Several guide pulleys 211 are integrated with the rotating rod 21 and are all uniformly installed on the supports 1.

[0019] The outer surface of the vertical rod 24 is threaded, and a locking nut 242 is threaded to the outer surface of the vertical rod 24. A spring 241 is sleeved on the outside of the vertical rod 24, and a rubber sleeve 243 is sleeved on the outside of the spring 241. The spring 241 is used to apply a pushing force to the moving plate 23, and the locking nut 242 is located on the top of the moving plate 23.

[0020] The top of spring 241 is fixedly connected to the bottom of movable plate 23, the bottom of spring 241 is fixedly connected to the top of support 1, the top of rubber sleeve 243 is fixedly connected to the bottom of movable plate 23, and the bottom of rubber sleeve 243 is fixedly connected to the top of support 1.

[0021] The bending mechanism 3 includes a first fixed plate 31 and a third fixed plate 33 fixedly connected to the right support 1. A second fixed plate 32 is fixedly connected to the right side of the left support 1. The second fixed plate 32 has a circular hole 321 inside. A rotating ring 331 is fixedly connected to the bottom of the third fixed plate 33. A square block 322 is fixedly connected to the top of the second fixed plate 32. A threaded shaft 323 is fixedly connected to the top of the square block 322. A second locking nut 324 is threaded onto the outer surface of the threaded shaft 323. Rotating the second locking nut 324 counterclockwise releases the bending mechanism. In addition to fixing the two supports 1, the other support 1 is then rotated and adjusted, and the rotating ring 331 rotates within the round hole 321, allowing the support 1 to maintain stable rotation adjustment. When it is rotated to a suitable angle, the locking nut 2 324 is turned clockwise with a wrench, and the other support 1 is fixed, so that the cable can be laid and guided in a bend, meeting different laying requirements and improving the aesthetics after laying; the fixing plate 33 is set below the fixing plate 1 31, and the fixing plate 2 32 is set below the fixing plate 33.

[0023] The rotating ring 331 is set inside the circular hole 321. The rotating ring 331 is rotatably connected to the second fixed plate 32 through the bearing.

[0024] One specific application of this embodiment is: In use, one of the supports 1 is first installed on the inner wall of the wind turbine with bolts. Then, the locking nut 242 on the moving plate 23 is rotated counterclockwise. At this time, the spring 241 will push the moving plate 23 with its elastic force, thereby moving the two rotating rods 21 away from each other and increasing the space between the upper and lower guide pulleys 211. Then, the operator passes the cable through the two guide pulleys 211 for quick laying and guidance. The guide pulleys 211 rotate on the support block 22 through the action of the rotating rods 21, so that the cable can be pulled more smoothly. After the cable is laid, the locking nut 242 is rotated clockwise to push and squeeze the moving plate 23. At this time, the upper and lower rotating rods 21 move closer to each other and clamp and fix the cable. This method can fix multiple cables at the same time without the need for individual operation by the operator. When the cable needs to be turned during the laying process, the locking nut 2 324 can be turned counterclockwise to release the fixation of the two supports 1. Then, the other support 1 can be rotated and adjusted, and the fixing plate 1 31 and the fixing plate 33 will rotate together. The rotating ring 331 will rotate in the round hole 321, and the fixing plate 1 31 will slide on the threaded shaft 323 through the arc groove 311, so that the other support 1 can be turned smoothly. After rotating to the appropriate angle, the locking nut 2 324 can be turned clockwise with a wrench to lock the fixing plate 1 31. At this time, the angle of the other support 1 is fixed. Then, the support 1 can be fixed to the inner wall of the wind turbine with screws, so that the cable can be laid and guided in a turning manner to meet different laying requirements.
