Adjustable suspension device for wind turbine tower

Abstract

The invention discloses an adjustable suspension device for a wind turbine tower. The adjustable suspension device comprises a turbine shaft, wherein a lifting device is mounted on the turbine shaft; the lifting device comprises a lifting motor; driving rollers are arranged on the turbine shaft and an output shaft of the lifting motor respectively; driving sleeves are mounted on the outer sides of the driving rollers through ratchet tooth structures respectively; a descending sleeve and an ascending sleeve are mounted outside the driving sleeves of the lifting motor and the turbine shaft through ratchet tooth structures respectively; elevator ropes are mounted on the descending sleeve and the ascending sleeve; elevators are mounted at the tail ends of the elevator ropes; a torque detection device is mounted on one side of the turbine shaft; a plurality of suspension devices are mounted on the side surface of the tower; and each suspension device comprises a guide rail device and a maintenance device. The adjustable suspension device has the characteristics that the elevator capable of guaranteeing the strength of the tower is provided, the tower can be automatically detected, and the suspension devices can be automatically maintained.

Description

technical field [0001] The invention relates to the technical field of suspension devices, in particular to an adjustable suspension device for a wind turbine tower. Background technique [0002] A wind turbine is a turbine powered by wind energy. It generates electricity at half the cost of conventional turbines. The new design generates as much power as a conventional wind turbine, but with blades half the diameter. The smaller blade size and other factors allow the new turbines to be clustered closer together than traditional turbines, increasing the amount of electricity produced per acre of land. [0003] Existing wind turbines need to be installed at high places, and the strength of the wind turbine tower needs to be ensured. When installing a lift in the tower, it is necessary to set more fixing holes on the tower, which weakens the strength of the tower. Therefore, usually the tower Usually only ladders and lighting devices are suspended in the frame, which makes ...

Problems solved by technology

[0003] Existing wind turbines need to be installed at high places, and the strength of the wind turbine tower needs to be ensured. When installing a lift in the tower, it is necessary to set more fixing holes on the tower, which weakens the strength of the tower. Therefore, usually the tower Usually only ladders and lighting devices are suspended in the frame, which makes the inspection of the tower and the maintenance of the suspension device very inconvenient. Therefore, it is designed to have a lift that can ensure the strength of the tower, and can automatically detect the tower and maintain the suspension device. Adjustable suspension for the turbine tower is necessary
