Technical Field

[0001] The utility model relates to the technical field of lifting platforms, and particularly relates to an efficient lifting operation platform for a wind power tower barrel. Background Art

[0002] A wind power tower barrel is the tower pole of a wind power generator, which mainly plays a supporting role in a wind power generating set and absorbs the vibration of the set at the same time. The lifting platform of a wind power tower barrel is an important and indispensable device in the wind power industry, and is mainly used for the convenience and comfort of internal maintenance, inspection of the wind power tower barrel and the up and down movement of personnel on the wind power tower barrel.

[0003] In the installation construction and maintenance process of the components of a wind power tower barrel, due to the need for high-altitude operations, two main methods are usually adopted to achieve this. 1. The method of using a crane to cooperate with a cage, where the crane is used to lift the cage to the designated height of the wind power tower barrel, and the staff complete the operation inside the cage. 2. The method of suspending people with ropes, where ropes are extended from the top of the wind power tower barrel and then used to suspend the staff for operation.

[0004] However, the crane itself has a maximum lifting height limit, which may not be able to meet the height requirements of all wind power tower barrels, and there are still certain safety hazards in the high-altitude suspended state. If the method of suspending people with ropes is adopted, the staff are in a suspended state and need to manually operate the ropes, which has great safety hazards and is not easy to move positions, making it inconvenient to construct different positions of the tower barrel.

[0005] To solve the above problems, the utility model proposes an efficient lifting operation platform for a wind power tower barrel. Content of the Utility Model

A first driving component for driving the lifting platform 1 to lift is arranged at the bottom end on the outside of the tower barrel main body 2. A rotating plate 5 is rotatably installed inside the lifting platform 1. A rotating groove 6 is formed on the lower end surface of the lifting platform 1. A gear ring 7 is rotatably installed inside the rotating groove 6. The gear ring 7 is fixedly connected to the rotating plate 5.

A support roller 12 is rotatably installed on the upper end surface of the top fixing frame 3 corresponding to the position of the lifting rope 11. The lifting rope 11 bypasses the support roller 12 and is fixedly connected to the upper end surface of the lifting platform 1.

[0032] Further, through holes 13 are formed in the lifting platform 1 and the top fixing frame 3 corresponding to the position of the lifting rope 11, and the lifting rope 11 passes through the inside of the through holes 13.

[0033] Further, a sliding groove 14 is formed in the upper end surface of the lifting platform 1, and the rotating plate 5 is rotatably installed inside the sliding groove 14.

[0039] Working principle:

[0040] During use, by starting the first motor 9, the output shaft of the first motor 9 rotates to drive the winding drum 10 to rotate. The winding drum 10 rotates to wind up the lifting rope 11. When the lifting rope 11 is wound up, it drives the lifting platform 1 to move upward. The lifting platform 1 moves upward on the three limiting rods 4. By arranging the three limiting rods 4, the lifting platform 1 moves upward more stably and is not easily affected by environmental factors. The lifting platform 1 is moved upward to the construction point.

[0041] If it is necessary to change the construction position, it is not necessary for the staff to move around. Start the second motor 15. The output shaft of the second motor 15 rotates to drive the gear 16 to rotate. The gear 16 rotates to drive the toothed ring 7 to rotate inside the rotating groove 6, and then drives the rotating plate 5 to rotate. The rotating plate 5 rotates to drive the staff to rotate around the axis of the tower barrel main body 2, so that the staff can inspect and construct the periphery of the tower barrel main body 2 without the need for the staff to move around or adjust, improving the safety of construction.

[0042] By arranging an anti-slip pad on the upper end surface of the rotating plate 5, it is avoided that the staff slips on the rotating plate 5.
