Description

Technical Field

[0001] The utility model relates to the technical field of wind power tower maintenance and construction, in particular to a flexible track fixing device for a wind power tower. Background Art

[0002] During use, oil and dirt accumulate on the outer wall of the wind turbine tower. If the oil and dirt are not cleaned in time, it will not only affect the appearance of the tower, but also corrode the tower surface and easily induce fire accidents. Due to the huge size of wind turbine towers, traditional manual cleaning operations are inefficient, dangerous and expensive. At present, some tower cleaning robots or devices have appeared, which can replace manual work to complete tower cleaning operations. Their up and down movement of the tower mainly relies on traction ropes as flexible tracks for traction and control.

[0003] For example, the patent with application number 202311325713.0 discloses a stable adsorption wind turbine tower cleaning device, which includes a permanent magnet block that can be adsorbed on both sides of the wind turbine tower, a winch and a cleaning robot for cleaning. The permanent magnet block is provided with a rolling groove wheel, and the two ends of the winch are respectively provided with tension springs connected to the traction rope. The traction ropes at both ends are connected to the two ends of the cleaning robot through the rolling groove wheel guide, which is used to control the cleaning route of the cleaning robot. The invention has a simple structure and is easy to operate, and can quickly clean the surface of the tower.

[0004] Another example is the patent with application number 201811467093.3, which discloses a device for automatically cleaning the tower of a wind turbine, including: a lifting system, a cleaning system, a water jet system, a control system and auxiliary accessories. The lifting system includes a main frame, a hoist for lifting and lowering the equipment, and a magnetic component for providing adsorption force. The hoist is connected to one end of a traction rope, and the other end of the traction rope is fixed in a rotatable wind turbine cabin. The hoist moves up and down along the traction rope, thereby driving the entire equipment to move up and down, thereby realizing the automation of the wind turbine tower cleaning process.

[0005] Based on the above search results, it was found that the traction rope of the two patents as the flexible track is adsorbed on the tower and fixed through a device containing magnetic components. This design is quick to disassemble and easy to operate, but due to the limited adsorption force of the magnetic components, there is a phenomenon that the flexible track is not firmly fixed, which leads to poor tower cleaning effect.

[0006] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and a flexible track fixing device for a wind power tower is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides a flexible track fixing device for a wind power tower to solve the problem that the flexible track of the existing tower cleaning robot is mostly fixed after being adsorbed on the tower by a device containing magnetic components, resulting in the flexible track being not firmly fixed and the tower cleaning effect being poor.

[0008] The utility model is realized through the following technical solutions:

[0009] Provided is a flexible track fixing device for a wind power generation tower, comprising a support block, wherein a fixed side plate is laterally connected to one side of the bottom of the support block, a strip hole is provided on the fixed side plate for matching bolts and nuts to connect the support block to the tower, a vertical surface of the support block away from the tower is convexly provided with two mutually parallel lugs, one of which is provided with a threaded through hole and is threadedly connected with a threaded locking rod, an end of the threaded locking rod located outside the lug is provided with a through hole in a direction perpendicular to the axis of the threaded locking rod, and a rotating rod is slidably connected in the through hole, and the flexible track can be locked and loosened between one end of the threaded locking rod located inside the lug and the other lug by the forward and reverse rotation of the threaded locking rod.

[0010] Furthermore, at least two anti-slip transverse grooves are formed on a side of the other lug facing the threaded through hole.

[0011] The lug forms an anti-skid transverse groove on one side facing the threaded through hole, which can increase the friction with the lower end of the flexible track, thereby ensuring the stability of the flexible track when the threaded locking rod presses the lower end of the flexible track, and effectively preventing the flexible track from falling out.

[0012] Furthermore, a curved surface having the same taper as that of the tower and which can fit the shape of the tower is formed on the other side elevation of the support block close to the tower.

[0013] One side elevation of the support block forms a tapered arc surface that fits the surface of the tower. The arc surface can be used to fit the outer wall of the tower, thereby making the support block more stable on the tower.

[0014] Furthermore, a vertical surface parallel to the tower axis is formed above the lug on one side of the support block away from the tower, and a flat sling in an annular shape is sleeved between the vertical surface and the tower outer wall to press the support block against the tower outer wall.

[0015] A vertical surface is arranged on one side of the support block away from the tower, and a flat sling is sleeved between the vertical surface and the outer wall of the tower to effectively limit the support block and ensure the stability of the upper part of the support block.

[0016] Furthermore, a groove having the same width as the flat sling is formed on the vertical surface, and the flat sling is sleeved in the groove.

[0017] A groove is formed on the vertical surface to limit the flat sling and prevent it from being displaced vertically, thereby enhancing the stability of the support block.

[0018] Beneficial effects of the utility model:

[0019] The utility model utilizes the tower anchor bolts and compression nuts in conjunction with the strip holes on the fixed side plates to fix the support blocks on the tower outer wall using the fixed side plates. At the same time, the arc-shaped surfaces matching the side surfaces of the support blocks and the tower outer wall can jointly realize the overall horizontal support and vertical fixation of the support blocks. The end of the threaded locking rod is locked with the lug facing the lower end of the flexible track, so that the flexible track can be stably fixed, thereby ensuring the cleaning effect of the tower cleaning robot.

[0033] The other lug 5 is formed with at least two anti-slip transverse grooves 6 on one side facing the threaded through hole 4. Figure 6 As shown, in this embodiment, three anti-slip transverse grooves 6 are provided.

[0034] The other side elevation of the support block 1 close to the tower 10 is formed with an arc surface which has the same taper as the tower 10 and can fit the shape of the tower 10 .

[0035] The use of the utility model:

[0036] When using the device, first adjust the vertical position of the device, pass the tower anchor bolt 9 through the strip hole 7 on the fixed side plate 3, adjust the horizontal position of the device so that the support block 1 is supported on the outer wall of the tower 10, and use the clamping nut 8 to cooperate with the tower anchor bolt 9 to clamp the fixed side plate 3 to complete the horizontal and vertical fixation of the device. After the device is fixed, fix the upper end of the flexible track 11 in the rotatable wind turbine cabin, then adjust the lower end position of the flexible track 11 so that the flexible track 11 is placed between a pair of lugs 5 of the support block 1, and then rotate the threaded locking rod 2 forward, gradually approach the lug 5 along its other end, and lock the lower end of the flexible track 11 with the anti-skid horizontal groove 6 on the surface of the lug 5, and finally complete the stable fixation of the flexible track 11 to ensure the cleaning efficiency of the tower cleaning robot.
