Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0014] like figure 1 and figure 2 As shown, a wind rotor locking device for a wind power generating set includes a hydraulic locking cylinder 1 that is fixed on the hub 2 to rotate with the hub 2 through bolt connections and a rotor locking flange 4 that is fixed on the transmission chain casing and remains stationary. On the hydraulic locking cylinder 1 there is a locking bolt 3 that can be locked and released with the wind wheel locking flange 4 through expansion and contraction, and the hydraulic locking cylinder 1 is connected with a hydraulic control circuit that controls the expansion and contraction of the locking bolt. Correspondingly, there is a bushing 5 which locks and cooperates with the locking bolt 3 protruding from the front. The bushing 5 is provided wi...

Abstract

The invention discloses a wind wheel locking device for a wind generating set. The locking device comprises a hydraulic locking cylinder fixed and connected on a hub through a bolt and rotated with the hub and an actionless wind wheel locking flange, wherein the hydraulic locking cylinder is provided with a locking pin which is used for locking and loosing the wind wheel locking flange through stretching; and a hydraulic control circuit is arranged on the hydraulic locking cylinder and used for controlling the stretch of the locking pin, and the wind wheel locking flange is correspondingly provided with a lining which is matched with the front extended locking pin in locking manner. The invention aims to provide a wind wheel hydraulic locking device of a wind generating set, which has the advantages of simple structure, small volume and convenience in operation, is safe and reliable in operation, and is automatically controlled.

Description

[technical field] [0001] The invention relates to a wind wheel locking device, in particular to a wind wheel locking device of a wind power generating set. [Background technique] [0002] When the wind turbine is being maintained and overhauled, the wind rotor must be locked to prevent safety accidents caused by the rotation of the wind rotor. At present, most of the wind wheel locking devices used in wind power generators are mechanical manual locking devices. The operation is troublesome, the failure rate is high, and there are certain requirements for operators. In addition, due to the new type of wind power generator of our company, the impeller locking device is designed outside the hub, and the traditional mechanical manual locking device is not suitable for impeller locking. [Content of the invention] [0003] The present invention overcomes the disadvantages of the above-mentioned technologies, and provides a hydraulic locking device for a wind wheel of a wind po...
