Wind power generation tower attached pick crane

Abstract

The invention discloses a wind power generation tower attached pick crane, which comprises a crane boom, a post-tensioning steel strand, a ground anchor oil cylinder, a hoisting steel strand, a hydraulic lifting system, a telescopic oil cylinder and a stretching steel strand. The crane boom is hinged to the top of a wind power generation tower, the hoisting part of the crane boom stretches over the top of the wind power generation tower, and one end of the hoisting part of the crane boom is connected to the post-tensioning steel strand, the other end of which is in connection with the ground anchor oil cylinder fixedly disposed on the ground. The other end of the hoisting part of the crane boom is connected to the hoisting steel strand, the other end of which is connected to the hydraulic lifting system. The hydraulic lifting system is in connection with a fan engine room. The telescopic oil cylinder is fixedly disposed at a position between the middle part and the lower part of the wind power generation tower. The telescopic rod of the telescopic oil cylinder is in connection with the hoisting steel strand. The top of the wind power generation tower is hinged with the stretching steel strand, the other end of which is hinged to the support part of the crane boom. The equipment provided by the invention can be mounted and used repeatedly, and has the advantages of large one-time hoisting weight, great hoisting height, one hoisting time, cost saving, and the like.

Description

[0001] technical field [0002] The invention belongs to the technical field of fan hoisting, and in particular relates to a wind power tower-attached crane. [0003] Background technique [0004] As my country pays more and more attention to the wind power industry, some large-scale wind power projects have begun to invest in construction. While providing green and clean energy to the society, they have also brought business opportunities to the wind power installation industry, especially the wind turbine construction and hoisting industry. The working environment of wind turbine hoisting equipment is relatively special. The lifting height of the equipment is high, the lifting load is large, and it is necessary to avoid collision between the wind turbine and the tower, so the requirements for the hoisting system are relatively high. At present, the hoisting process is mainly completed by crawler cranes and truck cranes, which have the problems of inconvenient hoisting and...
