Description

Technical Field

[0001] This utility model belongs to the field of wind turbine engineering technology, and in particular relates to a wire tensioning device for wind turbine engineering. Background Technology

[0002] The cable tensioning device is crucial in wind turbine projects. It ensures that the cable maintains appropriate tension during the laying process, preventing slack or excessive tightness. The device is easy to operate, highly stable, and can improve construction efficiency and quality. In wind turbine projects, it provides reliable protection for cable laying and helps achieve efficient transmission of green energy.

[0003] Some existing wire tensioning devices often use a motor to drive the wire roller to rotate during wire feeding and unloading. When the motor stops while feeding, inertia is often generated, which may cause the wire roller to rotate back, thereby changing the tension of the cable. The cable may become slack and droop, making it more susceptible to external impacts and friction during subsequent use, resulting in damage to the cable sheath. Utility Model Content

[0004] The purpose of this utility model is to provide a wire tensioning device for wind turbine engineering. By setting an anti-rotation mechanism, it solves the problem of inertia that often occurs when the motor stops rotating to release wire, which may cause the wire roller to rotate.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] This utility model is a wire laying and tensioning device for wind turbine engineering, including a base plate and a movable plate. The base plate is provided with an anti-rotation mechanism and an auxiliary mechanism.

[0007] Furthermore, the anti-rotation mechanism includes two wire feeding frames fixedly connected to the top of the base plate. A motor is fixedly connected to the rear side of the wire feeding frame located on the rear side. The output end of the motor is fixedly connected to a rotating shaft via a coupling. The front end of the rotating shaft passes through the two wire feeding frames and is rotatably connected to the two wire feeding frames. A wire roller is fixedly connected to the rotating shaft. A turntable is fixedly connected to the front end of the rotating shaft. The front end of the turntable has several slots. Two positioning rods are slidably connected to the front side of the moving plate. The rear ends of the two positioning rods pass through the moving plate and extend to the inner wall of the slots and are slidably connected to the slots. A spring is sleeved on each of the two positioning rods.

[0008] Furthermore, a slide rail is fixedly connected to the top of the base plate, and a slider is slidably connected to the inner wall of the slide rail. The top of the slider is fixedly connected to the movable plate.

[0009] Furthermore, a connecting block is fixedly connected to the right side of the slider, a hydraulic cylinder is fixedly connected to the top of the base plate, and the rear side of the connecting block is fixedly connected to the output shaft of the hydraulic cylinder.

[0010] Furthermore, the auxiliary mechanism includes a moving component and a limiting component. The moving component includes two support plates 1 fixedly connected to the top of the base plate. A motor 2 is fixedly connected to the rear side of the support plate 1 located on the rear side. A threaded rod is fixedly connected to the output end of the motor 2 via a coupling. The front end of the threaded rod extends to the support plate 1 located on the front side and is rotatably connected to the two support plates 1.

[0011] Furthermore, an internal threaded block is threadedly connected to the threaded rod, a slide rod is fixedly connected between the two support plates, the internal threaded block is slidably connected to the slide rod, and an mounting plate is fixedly connected to the top of the internal threaded block.

[0012] Furthermore, the limiting assembly includes a bidirectional threaded rod rotatably connected to the top of the mounting plate, on which two C-shaped plates are threadedly connected.

[0013] Furthermore, a knob is fixedly connected to the front end of the bidirectional threaded rod, a limit rod is fixedly connected to the top of the mounting plate, and both of the C-shaped plates are slidably connected to the limit rod.

[0014] Furthermore, several dampers are fixedly connected to the inner walls of both of the C-shaped plates, and springs are sleeved on each of the dampers. Arc-shaped plates are slidably connected to the inner walls of both of the C-shaped plates, and the sides of the two arc-shaped plates that are far apart from each other are fixedly connected to the corresponding dampers.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting up an anti-rotation mechanism, when motor one is started, the rotating shaft rotates, which in turn drives the turntable to rotate. When the turntable rotates, it contacts the positioning rod. When the positioning rod contacts the slot, it moves, causing spring one to contract. The anti-rotation mechanism prevents the inertia generated when the motor stops rotating during wire feeding from causing the wire roller to rotate back, thereby changing the tension of the cable. This reduces unnecessary stress on the cable, extends its service life, and lowers maintenance costs. It also helps maintain the stability of the cable and prevents accidental rotation of the wire roller from causing the cable to suddenly loosen or tighten, which could pose a safety threat to construction personnel.

[0017] 2. By setting up an auxiliary mechanism, rotating the knob drives the bidirectional threaded rod to rotate, which in turn moves the C-shaped plate on the limit rod. The movement of the C-shaped plate causes the arc plate to move. When the arc plate is impacted, it causes the second spring and the arc plate to contract. The auxiliary mechanism restricts the cable within a limited space, thus constraining the range of motion of the cable when it sways. This reduces sudden tension changes caused by large swings, helps maintain the balance of cable tension, avoids fluctuations in tension, improves the service life of the cable, and reduces cable fatigue damage caused by uneven tension.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] Please see Figure 1-6 As shown, this utility model is a wire laying and tensioning device for wind turbine engineering, including a base plate 1 and a movable plate 27. The base plate 1 is equipped with an anti-rotation mechanism 2 and an auxiliary mechanism 3. The anti-rotation mechanism 2 includes two wire laying frames 21 fixedly connected to the top of the base plate 1. A motor 22 is fixedly connected to the rear side of the rear wire laying frame 21. The output end of the motor 22 is fixedly connected to a rotating shaft 23 via a coupling. The front end of the rotating shaft 23 passes through the two wire laying frames 21 and is rotatably connected to them. A wire roller 24 is fixedly connected to the rotating shaft 23. A turntable 25 is fixedly connected to the front end of the rotating shaft 23. The front end of the turntable 25 has several slots 26. Two positioning rods 28 are slidably connected to the front side of the movable plate 27. The rear ends of the two positioning rods 28 are... The rear ends of the two positioning rods 28 extend through the moving plate 27 to the inner wall of the slot 26 and slide in connection with the slot 26. Springs 29 are fitted on both positioning rods 28. A slide rail 210 is fixedly connected to the top of the base plate 1. A slider 211 is slidably connected to the inner wall of the slide rail 210. The top of the slider 211 is fixedly connected to the moving plate 27. A connecting block 212 is fixedly connected to the right side of the slider 211. A hydraulic cylinder 213 is fixedly connected to the top of the base plate 1. The rear side of the connecting block 212 is fixedly connected to the output shaft of the hydraulic cylinder 213. The anti-rotation mechanism prevents the inertia generated when the motor stops rotating during wire feeding from causing the wire roller to rotate, thereby changing the tension of the cable, reducing unnecessary stress on the cable, and extending the service life of the cable.

[0030] Auxiliary mechanism 3 includes a moving component and a limiting component. The moving component includes two support plates 31 fixedly connected to the top of the base plate 1. A motor 32 is fixedly connected to the rear side of the rear support plate 31. The output end of the motor 32 is fixedly connected to a threaded rod 33 via a coupling. The front end of the threaded rod 33 extends to the front support plate 31 and is rotatably connected to the two support plates 31. An internal threaded block 34 is threaded onto the threaded rod 33. A slide rod 35 is fixedly connected between the two support plates 31. The internal threaded block 34 is slidably connected to the slide rod 35. A mounting plate 36 is fixedly connected to the top of the internal threaded block 34. The limiting component includes a bidirectional threaded rod 37 rotatably connected to the top of the mounting plate 36. A threaded rod 37 is threaded onto the bidirectional threaded rod 37. The cable has two I-shaped plates 38 connected to the threaded connection. A knob 310 is fixedly connected to the front end of the bidirectional threaded rod 37. A limit rod 39 is fixedly connected to the top of the mounting plate 36. Both I-shaped plates 38 are slidably connected to the limit rod 39. Several dampers 311 are fixedly connected to the inner walls of both I-shaped plates 38. Springs 312 are fitted on the dampers 311. Arc plates 313 are slidably connected to the inner walls of both I-shaped plates 38. The sides of the two arc plates 313 that are far apart from each other are fixedly connected to the corresponding dampers 311. The cable is restricted to a limited space by the auxiliary mechanism, so that the range of motion of the cable is constrained when it swings, reducing the sudden tension changes caused by large swings and helping to maintain the balance of cable tension.

[0031] A specific application of this embodiment is as follows: When motor 22 is started, its rotation drives shaft 23 to rotate, which in turn drives roller 24 to rotate. When motor 22 rotates forward, roller 24 begins to unwind. When motor 22 rotates in reverse, roller 24 retracts the thread. When motor 22 rotates forward, it drives shaft 23 to rotate, which in turn drives turntable 25 to rotate. Due to the design of the slot 26 and the rear end of the positioning rod 28, the slot 26 and the rear end of the positioning rod 28 cooperate with each other. When motor 22 rotates forward, the positioning rod 28 is not restricted by the slot 26, causing its rear end to contact the slot 26 and move, thus causing spring 29 to contract. When motor 22 rotates in reverse, the positioning rod 28 contacts the slot 26, and the slot 26 engages with the positioning rod 28. The positioning rod 28 blocks the turntable 25, preventing it from rotating. This, in turn, prevents the rotating shaft 23 from rotating. Therefore, when the motor 22 rotates forward to feed the cable, the rotating shaft 23 may generate inertia when the motor stops. Under the action of inertia, the rotating shaft 23 may rotate back, which will affect the cable tension. Therefore, the cooperation between the positioning rod 28 and the slot 26 can prevent the rotating shaft 23 from rotating back, avoiding the impact on the cable tension. When the cable needs to be retrieved and the motor reverses, the hydraulic cylinder 213 is activated. The hydraulic cylinder 213 drives the connecting block 212 to move, which in turn causes the connecting block 212 to drive the slider 211 to slide within the slide rail 210. When the slider 211 moves, it drives the moving plate 27 to move, which moves the positioning rod 28 away from the turntable 25, thus preventing the motor 22 from being affected when it reverses.

[0032] When the cable is retracted, motor 32 is activated. Motor 32 drives the threaded rod 33 to rotate, which in turn moves the internal threaded block 34 on the slide rod 35. The movement of the internal threaded block 34 moves the mounting plate 36, which in turn moves the cable between the I-shaped plates 38. This ensures that during cable retraction, the cable moves along with the internal threaded block 34, preventing the cable from remaining wound in one place while winding around the cable roller 24, thus avoiding extreme situations where the cable becomes entangled on the roller 24. During cable feeding or retraction, the cable is passed between the two I-shaped plates 38, and knob 310 is rotated. The knob 310 drives the bidirectional threaded rod 37 to rotate. When the bidirectional threaded rod 37 rotates, it drives the inverted plate 38 to move on the limiting rod 39. When the inverted plate 38 moves, it drives the arc plate 313 to move, thereby limiting the cable and confining it to a limited space as much as possible. This prevents the cable from swinging excessively during the cable feeding and rewinding process, which would affect the cable tension and recovery effect. At the same time, when the cable swings and hits the arc plate 313, the arc plate 313 transmits the impact force generated by the impact to the second spring 312 and the damper 311 for buffering and dispersion, preventing the cable from swinging and damaging the equipment.
