Hoisting maintenance device and wind driven generator

Abstract

The invention discloses a hoisting maintenance device and a wind driven generator and belongs to the technical field of wind power generation. The hoisting maintenance device comprises a supporting mechanism, a guiding mechanism, a rotating mechanism and a hoisting assembly. The guiding mechanism comprises a cross beam and a longitudinal beam; the rotating mechanism is rotatably connected to the guiding mechanism; and the hoisting assembly is used for hoisting a to-be-hoisted part along a vertical direction and can slide on the guiding mechanism and the rotating mechanism. The hoisting maintenance device arranged in a cabin of the wind driven generator not only can hoist damaged parts in the cabin of the wind driven generator and new parts out of the cabin anytime as needed for improving the maintenance and replacement efficiency favorably, but also is not affected by external weather conditions during hoisting, so that the hoisting maintenance device further can meet the using demands. In addition, the hoisting maintenance device is provided with the hoisting assembly sliding on the guiding mechanism and the rotating mechanism, so that the hoisting range is enlarged and the universality is improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a lifting maintenance device and a wind power generator. Background technique [0002] With the gradual deterioration of the energy situation, wind energy, as a renewable and non-polluting natural energy, has gradually received attention. A wind turbine is a device that converts wind energy into electrical energy, and a wind turbine gearbox is an essential component of a wind turbine. When the wind turbine is in use, it needs to be installed high above the ground. The wind turbine gearbox is located in the nacelle of the wind turbine generator. When the shafting components on the wind turbine gearbox are damaged and need to be repaired, the existing technology generally rents a ground crane and uses the ground The crane lifts the new shafting components to the nacelle, and then repairs and replaces the wind power gearbox. [0003] However, renting a ground crane t...

Problems solved by technology

[0003] However, renting a ground crane to replace the shafting parts of the gearbox has the following disadvantages: 1. The rental cost of the ground crane is very high; 2. The ground crane is greatly affected by the weather (the wind speed exceeds 10m / s and cannot be hoisted, and it cannot be hoisted when it rains) ; 3. It is necessary to set up the tooling frame on site. Due to the complicated erection of the tooling frame and the long construction time, the efficiency of maintenance and replacement is low
