Abstract

The invention relates to a hub-locking device of a wind-driven generator, which comprises a brake disk, a brake ring, a locking pin and a hydraulic system. The upper surface of the brake ring is provided with a lug boss and a locking support; a hydraulic cylinder is arranged above the locking support; an oil hole I and an oil hole II are arranged on the inner wall of the hydraulic cylinder; the brake disk is arranged between the lug boss and a middle ring of the locking support; the middle ring of the locking support is provided with a signal detector I; a signal detector II is arranged in the same radial position as the signal detector I on the brake ring; n small contraposition holes are arranged in the same radial position as the signal detector I on the brake disk in the circumferencedirection; the locking pin capable of repeatedly moving up and down is arranged in the hydraulic cylinder; the middle ring of the locking support, the brake disk and the lug boss are uniformly provided with pin holes suitable for the locking pin in size; the hydraulic system is mounted in a cabin and connected with an oil pipe I and an oil pipe II; the oil pipe I is connected with the oil hole I;and the oil pipe II is connected with the oil hole II. The invention has simple operation and accurate contraposition and saves time and labor.

Description

technical field [0001] The invention relates to a hub locking device, in particular to a hub locking device for a wind power generator. Background technique [0002] When maintaining the hub and blades of the wind turbine, the hub must be locked. The existing single-bearing direct-drive wind turbine mainly locks the wheel hub through a set of hydraulic locking device on the main bearing: the hydraulic locking pin of the hydraulic locking device passes through the through hole on the brake disc of the hydraulic locking device , inserted into the support hole of the brake ring of the hydraulic locking device to realize the locking of the hub. At present, the locking operation of the hub is mainly realized by manual operation. When the hub turns to a certain position and needs to be locked, first, it must be manually judged whether the through hole on the brake disc is aligned with the support hole on the brake ring, and the hydraulic locking pin can only be inserted after al...
