Hoisting tool for variable pitch component of wind power generator

Abstract

The invention relates to the technical field of variable pitch component mounting, in particular to a hoisting tool for a variable pitch component of a wind power generator. The hoisting tool comprises a C-shaped bracket; lifting lugs are arranged on an upper transverse rod of the C-shaped bracket; a fixing hoop, an angle locating tool and a handle are arranged on a lower transverse rod of the C-shaped bracket; the handle is arranged at the lower end of a vertical rod of the C-shaped bracket; the angle locating tool comprises a locating hoop and a hydraulic ejection rod from the bottom up sequentially; the fixing end of the hydraulic ejection rod is fixed to the left end of the lower transverse rod; the extension end of the hydraulic ejection rod is fixedly connected with the upper end of the locating hoop; the fixing hoop is fixed at the right end of the lower transverse rod; antiskid friction grains are formed in the surface of a holding part of the handle; and ejection rod control buttons are arranged at the two ends of the holding part. The mounting angle of the variable pitch component can be adjusted; through optimization on the structure of the handle, the use comfort and the use safety of staff are improved, and the ejection rod control buttons can be pressed conveniently to achieve the purpose of controlling the hydraulic ejection rod; and the hoisting tool is simple to operate and convenient to use.

Description

Technical field [0001] The invention relates to the technical field of pitch assembly installation, in particular to a hoisting tool for the pitch assembly of a wind generator. Background technique [0002] The center of gravity of the wind turbine pitch reducer is outside the mounting flange, which is difficult to hoist and is installed deep in the hub cavity. The small pitch teeth need to protrude from the mounting hole and mesh with the large gear ring of the pitch bearing. During installation, the gearbox needs to be fed into the hub and meshed with the inner gear ring of the pitch bearing from the inside to the outside to successfully complete the assembly. The original technology uses the "C" type tooling spreader, which cannot fully meet the requirements of the working conditions. The spreader is slow to disassemble and assemble, it is difficult to hoist the pitch gear box, requiring manual adjustment, low assembly efficiency and difficult assembly. Summary of the inventi...

AI Technical Summary

Problems solved by technology

The original technology adopts the "C" type tooling spreader, which cannot fully meet the requirements of the working conditions. The disassembly and assembly of the spreader is slow, and it is difficult to lift the pitch gearbox horizontally. Manpower adjustment is required, and the assembly efficiency is low and difficult to assemble.
