Derusting device for inner wall of wind power generation tower

Abstract

The invention relates to the technical field of wind power generation tower drum inner wall machining equipment, in particular to a wind power generation tower drum inner wall rust removal device which comprises a first rotating shaft, the axis of the first rotating shaft coincides with the axis of a tower drum, and the first rotating shaft is in transmission connection with a power device used for driving the first rotating shaft to rotate and move in the axis direction of the tower drum. At least two rust removal assemblies are arranged in the circumferential direction of the first rotating shaft, the multiple rust removal assemblies are distributed at equal angles, the free end of the second connecting rod is rotationally connected with a supporting frame, the side, close to the inner wall of the tower drum, of the supporting frame is rotationally connected with a second rolling wheel, and the axis of the second rolling wheel is parallel to the axis of the tower drum. The supporting frame is rotationally connected with a polishing brush, the polishing end of the polishing brush makes contact with the inner wall of the tower barrel, and the polishing brush is in transmission connection with the second rolling wheel. The device is simple in structure, capable of achieving multidirectional grinding, capable of changing according to the change of the diameter of the inner wall of the tower drum and good in adaptability.

Description

technical field [0001] The invention relates to the technical field of processing equipment for the inner wall of a wind power generation tower, in particular to a rust removal device for the inner wall of a wind power generation tower. Background technique [0002] The inner diameter of the wind power tower is several meters or even tens of meters, and the length can reach tens of meters or even hundreds of meters. The tower is prepared by welding and assembling multiple shorter cylinders in sequence. Spray paint on the inner wall of the tower. Before painting, it is necessary to carry out the derusting step on the inner wall. Because of the limited length of the traditional tower derusting structure, it can only be assembled with one section for derusting and derusting. Derusting is more troublesome, and the tower is a conical frustum structure. It is necessary to frequently adjust the arm length of the derusting structure, which is cumbersome to operate.
