Novel climbing wind power maintenance lifting platform capable of bearing heavy load and application method

Abstract

The invention discloses a novel climbing wind power maintenance lifting platform capable of bearing heavy load and an application method. The lifting platform comprises a climbing device, a clamping device and a lifting device, wherein the climbing device is formed by a hydraulic cylinder connected with an upper platform and a lower platform; climbing and fixation are achieved when the lifting device is cooperated with the clamping device; when the upper platform is fixed, the hydraulic cylinder retracts, and the lower platform connected with the hydraulic cylinder is lifted to a certain height; the hydraulic cylinder is tightly close to the lower platform and then fixed; when the hydraulic cylinder extends, the upper platform connected to the hydraulic cylinder is lifted to a certain height; with the repeated process, climbing and fixation can be realized; the lifting device consists of a revolving platform, a hydraulic supporting device, a supporting column device and a suspension arm; the revolving platform is fixedly connected to the upper platform, so rotational adjustments of the suspension arm can be achieved; the bearing suspension arm is arranged over the revolving platform, so extension and folding can be realized; when a lifter is supported on the upper part of a draught fan case by the supporting column, heavy load can be lifted; and when the supporting column is retracted, light components in the draught fan can be lifted, so the whole draught fan can be maintained.

Description

technical field [0001] The invention relates to a hoisting device for wind power maintenance, in particular to a hoisting platform suitable for maintenance of a large wind turbine that needs to realize heavy-duty hoisting. Background technique [0002] Against the background of global warming and increasing environmental pollution, the importance of renewable and clean energy has gradually come to the fore. As a safe, renewable, non-polluting, and abundant green energy, wind energy has attracted more and more attention in recent years. According to the statistics of the Global Wind Energy Council, from 2001 to 2013, the compound annual growth rate of the cumulative installed capacity of wind power in the world was 24.08%. This increased to 318,317MW on December 31, 2013. Therefore, wind power generation is an industry with great development potential. [0003] my country's southeastern coastal areas and western regions are rich in wind resources, and wind power technology...

AI Technical Summary

Problems solved by technology

At present, the following problems generally exist in the lifting platform for maintenance of wind turbines invented at present. First, the lifting capacity of the current lifting platform for maintenance of wind turbines is small due to the limitation of the hydraulic fulcrum, which cannot meet the needs of lifting heavy parts such as blades; secondly, the current The hoisting platforms for wind turbine maintenance all use winches and other equipment to lift the lifting platforms for wind turbine maintenance, which increases the number of equipment and costs, and is limited by the site; Realize automatic climbing and recovery
