Supporting arm structure for operation and maintenance of wind power gear box

Abstract

A supporting arm structure for operation and maintenance of a wind power gear box is mainly composed of a first supporting frame, a first nut, a first washer, a first bolt, a second supporting frame,a second washer, a second nut, a screw rod, a first arm, a second bolt and a second arm. The first supporting frame and the second supporting frame are connected to form a split supporting frame by using the first bolt, the first washer and the first nut through connecting flanges at the connecting ends of the first supporting frame and the second supporting frame, and the second supporting frameis connected with the outwards-extending screw rod; at least one section of the second arm and at least one section of the first arm are connected in a penetrating mode at the connecting ends of the at least one section of the second arm and at least one section of the first arm through the second bolt and then fixed to form a split arm by using the second nut and the second washer; and the secondsupporting frame penetrates through the other connecting end of the first arm through the screw rod, and the second supporting frame and the other connecting end of the first arm are fixed together by using the second nut and the second washer, so that the split supporting frame and the split arm are connected to form a whole supporting arm. The supporting arm structure has the characteristics ofbeing simple in structure, low in cost, and convenient to operate and use, and can reduce the labor intensity of workers and improve the efficiency.

Description

technical field [0001] The invention relates to a support arm structure for wind power gearbox operation and maintenance, and belongs to the technical field of wind power generation equipment operation and maintenance tooling. Background technique [0002] The operation and maintenance of wind power gearbox will involve the disassembly and assembly process of parts. Many parts that need to be disassembled are complex in structure and heavy in weight. The disassembly and assembly of parts cannot be realized by manpower alone. It must be realized by tooling, but the space structure in the nacelle is limited. , there is no small crane, and there is no supporting point to hang the chain hoist in the engine room, so it is very difficult to maintain and install the gearbox in the engine room, which has become a major problem in the operation and maintenance work. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior a...
