Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary tools for wind power equipment, specifically a ring-type guy rope hoisting auxiliary device for wind turbine towers. Background Technology

[0002] In recent years, with the accelerated trend of wind turbine generators becoming larger, the tower height has generally exceeded 100 meters, and the requirements for stability control during their installation and maintenance have become increasingly stringent.

[0003] The lifting process during wind turbine tower installation is often disrupted by strong winds. Strong winds significantly impact the lifting process, potentially causing increased swaying of the load, leading to risks of disengagement, impact, or falling, threatening the safety of personnel and equipment below. Furthermore, strong winds can impair the operator's precise control over the load, increasing the difficulty of the operation. Currently, ground-anchored guy ropes are commonly used for protection; however, traditional ground-anchored guy rope methods have the following problems:

[0004] (1) It is 150-200 meters long and heavy, making it difficult to carry and transport;

[0005] (2) It is easy to get tangled, which increases the complexity and danger of operation;

[0006] (3) Installation requires the cooperation of multiple people;

[0007] (4) Personnel must be stationed on the ground to control the use, which poses a risk to personal safety.

[0008] (5) It occupies a large amount of ground space.

[0009] Therefore, there is an urgent need for a new type of guy rope device with a simplified structure, no anchorage required, and dynamic stability to meet the wind power industry's pressing needs for efficient, safe, and environmentally friendly operations. Utility Model Content

[0010] To address the shortcomings of existing technologies, this utility model discloses a circumferential guy rope hoisting auxiliary device for wind turbine towers, in order to solve the problems mentioned in the background art.

[0011] To achieve the above objectives, this utility model provides the following technical solution: a wind turbine tower hoisting auxiliary device with a spiral-type guy rope, comprising several rolling components installed on the surface of the rope;

[0012] The rolling assembly includes a roller, a sleeve body, and locking rings. The roller is fitted onto the outer wall surface of the sleeve body and is rotatably connected to the sleeve body. The locking rings are symmetrically located on both sides of the sleeve body. A through groove is provided inside the sleeve body, through which the rope passes. Fixed sleeves are provided on both sides of the sleeve body. Several pressure plates are arranged around the outer ends of the fixed sleeves, with a gap between the pressure plates. The locking rings on both sides are fitted onto the fixed sleeves and are interlocked with each other. The locking rings squeeze the pressure plates, which in turn squeeze the rope through the gap between the pressure plates. The rope is wrapped around the outer wall of the tower and is connected to the hoisting equipment through a locking buckle, assisting the hoisting equipment in lifting and lowering the object. During the lifting and lowering process, the rope maintains rolling friction with the outer wall of the tower through the roller.

[0013] Preferably, the inner side of the roller is provided with an annular locking block, and the outer wall of the sleeve body at the middle position is provided with a sliding locking groove. The annular locking block and the sliding locking groove are engaged with each other and are rotatably connected.

[0014] Preferably, the outer wall of the fixed sleeve is provided with a first thread structure, and the inner wall of the inner end of the locking ring is provided with a second thread structure. The first thread structure and the second thread structure cooperate with each other, and the locking ring and the fixed sleeve are rotated and tightened.

[0015] Preferably, the inner wall of the outer end of the locking ring is provided with an inclined annular surface, which tends to contract near the outer end, and the inclined annular surface is used to squeeze the outer wall of the pressure plate.

[0016] Preferably, a rotating knob is provided on the outer wall of the inner end of the locking ring, and the rotation of the locking ring is controlled by the rotating knob.

[0017] Preferably, the inner wall of the clamping plate is provided with a protruding structure, which contacts the surface of the rope to increase friction.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. In this utility model, the ring-type guy rope device and roller system are designed to be directly fitted onto the surface of the tower, replacing the traditional ground anchoring scheme. This eliminates the need for complex foundation construction and significantly shortens the installation time. The quick connection mechanism of the locking buckle and sling simplifies the operation process, reduces the operation cycle, and the lightweight design of the device facilitates transportation and reuse, adapting to frequent disassembly and assembly needs.

[0020] 2. In this utility model, the tower outer wall fixing method is adopted, which completely eliminates the dependence of traditional guy ropes on the standing position and anchor point of ground workers, avoiding safety risks such as falling objects from heights and anchor failure; the pure rolling friction mechanism between the rolling component and the tower greatly reduces rope wear, and with the dynamic adjustment of the counterweight rubber wheel, the vertical stability of the guy rope is ensured during the hoisting process, effectively preventing the tower from shifting or overturning.

[0021] 3. In this utility model, a modular rolling assembly with optional one-way swivel wheel, swivel wheel and counterweight rubber wheel can be installed to adapt to different tower diameters and hoisting force direction requirements, and realize longitudinal / lateral force adaptive rolling friction; the device is compatible with various operation scenarios such as wind turbine tower installation, maintenance and component replacement, while improving hoisting accuracy, reducing friction damage to the tower surface and extending the service life of the equipment.

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] Example: Figures 1-5 As shown, a wind turbine tower hoisting auxiliary device with a spiral guy rope includes several rolling components installed on the surface of the rope body 4, and the spacing between the rolling components can be adjusted according to the actual situation.

[0032] The rolling assembly includes a roller 1, a sleeve body 2, and a locking ring 3. The roller 1 is fitted onto the outer wall surface of the middle part of the sleeve body 2. An annular locking block 101 is provided on the inner side of the roller 1. A sliding groove 204 is provided on the outer wall of the middle part of the sleeve body 2. The annular locking block 101 and the sliding groove 204 are engaged with each other and are rotatably connected. The locking ring 3 is symmetrically located on both sides of the sleeve body 2. A through groove 201 is provided inside the sleeve body 2, through which the rope 4 passes. Through the through groove 201, fixed sleeves 202 are respectively provided on both sides of the sleeve body 2. A plurality of pressure plates 203 are arranged around the outer end of the fixed sleeve 202, and there is a gap between the pressure plates 203. Locking rings 3 on both sides are respectively sleeved on the fixed sleeves 202, and are mutually sleeved with the fixed sleeves 202 through the locking rings 3. The outer wall of the fixed sleeve 202 is provided with a first thread structure 205, and the inner wall of the inner end of the locking ring 3 is provided with a second thread structure 301. 05 cooperates with the second threaded structure 301. A rotating knob 303 is provided on the outer wall of the inner end of the locking ring 3. The rotating knob 303 controls the rotation of the locking ring 3. The locking ring 3 is rotated and tightened with the fixed sleeve 202. The locking ring 3 presses against the pressure plate 203. An inclined annular surface 302 is provided on the inner wall of the outer end of the locking ring 3. The inclined annular surface 302 tends to contract near the outer end. The inclined annular surface 302 presses against the outer wall of the pressure plate 203. The clamping plates 203 converge towards the center to compress the rope 4. The inner wall of the clamping plate 203 is provided with a protruding structure 206, which contacts the surface of the rope 4 to increase the friction between the rolling assembly and the rope 4. The rope 4 is wrapped around the outer wall of the tower 5 and is connected to the hoisting equipment through a locking buckle to assist the hoisting equipment in lifting and lowering the item. During the lifting and lowering process, the rope 4 maintains rolling friction with the outer wall of the tower 5 through the roller 1.

[0033] The roller 1 can be a unidirectional rotating wheel, or a fusible wheel that supports bidirectional rotation in both the longitudinal and transverse directions, to ensure that the guy rope maintains rolling friction in all directions and greatly reduces frictional resistance; at the same time, it can also be equipped with heavy rubber wheels as counterweights to ensure that the guy rope always maintains a stable vertical downward state.

[0034] In practice, the rolling assembly is first fitted onto the guy ropes and the spacing is adjusted to fit the size of the tower 5. The rotating knob 303 of the locking ring 3 drives it to engage with the fixed sleeve 202. The inclined ring surface 302 presses against the clamping plate 203, causing the inner protruding structure 206 to press the rope 4 to fix the assembly. Then, the guy ropes are wrapped around the outer wall of the tower 5 and connected to the lifting equipment lock. During lifting, the roller 1 forms rolling friction with the surface of the tower 5. The optional ferrule can support multi-directional rolling to reduce resistance, while the optional counterweight rubber wheel maintains the vertical stability of the guy ropes by gravity. During operation, the assembly spacing or locking pressure can be adjusted according to the actual situation to ensure a balance between friction and stability, ultimately achieving efficient and low-loss tower 5 lifting assistance.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
