Problems solved by technology

At present, before the maintenance of wind turbines, large-tonnage truck cranes are generally used to disassemble them, and then install them after completion. The operation efficiency is low, and the rental of cranes also greatly increases the maintenance cost of wind turbines.
If the maintenance crane is fixedly installed on the wind turbine, all wind turbines in the wind farm need to be equipped with one, the utilization rate of the maintenance crane is extremely low, and the cost is also greatly increased

Abstract

The invention provides a tower embracing device for a wind electricity overhauling crane. The tower embracing device for the wind electricity overhauling crane comprises an upper tower embracing device; the upper tower embracing device comprises a left hand embracing mechanism, a right hand embracing mechanism and a middle tower embracing ring; the left hand embracing mechanism and the right hand embracing mechanism are hinged with two ends of the middle tower embracing ring respectively. The tower embracing device enables a maintaining and detecting device to be conveniently fixed on a tower cylinder and to be detached conveniently; when the tower embracing device is in use, the upper tower embracing device embraces the tower cylinder tightly, and thus the operation need of the maintaining and detecting device is ensured; after overhauling, the upper tower embracing device is unfolded, and the overhauling crane is lowered and put in storage. The tower embracing device for the wind electricity overhauling crane can be suitable for overhauling of different wind driven generator sets, saves the maintaining cost of a wind power station greatly, and is simple in structure, low in cost and convenient to use.

Description

technical field [0001] The invention relates to a tower holding device, in particular to a tower holding device for a wind power maintenance crane. Background technique [0002] Wind energy is a renewable clean energy. In recent years, with the implementation of my country's "Renewable Energy Law", wind power development is developing at an unprecedented speed. At present, large-tonnage truck cranes are generally used to disassemble wind turbines before maintenance, and then install them after completion. The operation efficiency is low, and the rental of cranes also greatly increases the maintenance cost of wind turbines. If the maintenance crane is fixedly installed on the wind turbine, all the wind turbines in the wind farm need to be equipped with one, and the utilization rate of the maintenance crane is extremely low, which also greatly increases the cost. Therefore, how to facilitate the maintenance operation of the crane under the premise of lower cost is a probl...
