Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower maintenance technology, specifically a wind turbine hybrid tower maintenance platform. Background Technology

[0002] In the field of wind power generation, the hybrid tower (steel-concrete composite tower) is an important structure supporting the wind turbine. Combining the advantages of steel and concrete, in order to ensure safety, improve economic efficiency, and ensure long-term reliable operation of the equipment, the tower needs to be regularly inspected, which requires the use of an inspection platform.

[0003] CN221823976U discloses a wind turbine tower maintenance device and a wind turbine tower. The wind turbine tower maintenance device includes: a frame assembly, which is annular and sleeved on the outer periphery of the tower. The end of the frame assembly is provided with an annular groove around the outer periphery of the tower; a placement assembly, which includes a placement platform; and a driving assembly, which includes a first rolling element and a driving element. The first rolling element matches the annular groove, and the driving element is disposed on the placement platform. The driving element has a driving shaft connected to the rolling shaft of the first rolling element and drives the first rolling element to move along the annular groove so that the placement platform is located on different sides of the tower circumference.

[0004] However, the aforementioned wind turbine tower maintenance device needs to be fixed to the wind turbine tower with bolts during use. However, the maintenance of the wind turbine tower is not limited to a single part, so the maintenance device needs to be repeatedly disassembled and reassembled, making the operation quite cumbersome. Utility Model Content

[0005] The purpose of this utility model is to provide a wind power hybrid tower maintenance platform to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A top plate is installed on the tower. The top plate is equipped with a positioning plate, a fall arrestor base plate, and a winch. A triangular platform is installed on the fall arrestor base plate.

[0009] A maintenance platform surrounds the tower, and the steel cable of the winch is connected to the maintenance platform;

[0010] The protective assembly includes a support mechanism and a fall arrest mechanism disposed on the maintenance platform. The winch is used to drive the maintenance platform to move. When the maintenance platform moves upward, the fall arrest mechanism moves along the fall arrest base plate and slides over the triangular platform. When the maintenance platform moves downward, the triangular platform abuts against the fall arrest mechanism. When the platform stops, the support mechanism abuts against the positioning mechanism.

[0011] Preferably, the maintenance platform includes a base plate surrounding the tower, an inner fence and an outer fence disposed on the base plate, a limiting guide plate disposed on the base plate and located between the positioning plate and the fall arrestor plate, and a connecting plate disposed on the inner fence and the limiting guide plate and connected to the steel cable.

[0012] Preferably, the support mechanism includes a support base disposed on the base plate, a support telescopic rod disposed on the support base, and a stop block disposed on the support telescopic rod.

[0013] Preferably, the support telescopic rod is used to drive the abutment block to fit against the positioning plate and fix the position of the inspection platform.

[0014] Preferably, the fall protection mechanism includes a fall protection base disposed on the base plate, a fall protection telescopic rod disposed on the fall protection base, a telescopic base disposed on the fall protection telescopic rod, a fall protection plate inserted on the telescopic base, a roller disposed on the fall protection plate, and a push spring disposed between the telescopic base and the fall protection plate.

[0015] Preferably, the anti-fall telescopic rod is used to push the roller against the anti-fall base plate when the inspection platform is moved up, so that the anti-fall plate moves along the anti-fall base plate. When the anti-fall plate moves to the inclined surface of the triangular platform, the anti-fall plate moves into the telescopic base and slides over the triangular platform.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model, through the setting of a winch and a maintenance platform, allows the maintenance platform to move along the tower and adjust the gap position. Through the setting of protective components, it provides fall protection when the maintenance platform moves and stops, preventing or slowing down the falling trend, and the support mechanism provides support force.

[0031] Working principle: When in use, when the winch 3 drives the maintenance platform to move upward, it pushes the roller 17 against the fall arrestor 16, causing the fall arrestor 16 to move along the fall arrestor base plate 19. When the fall arrestor 16 moves to the inclined surface of the triangular platform 4, the fall arrestor 16 moves into the telescopic base 15 and slides over the triangular platform 4. The fall arrestor 16 is located between the two triangular platforms 4, providing fall protection. When the maintenance platform moves downward under the drive of the winch 3, the maintenance platform moves at a constant speed and the fall arrestor telescopic rod 14 retracts in stages to avoid the triangular platform 4.
