Anti-lock screw mechanism and rotating part locking device for wind-driven generator

Abstract

The invention provides an anti-lock screw mechanism and a rotating part locking device for a wind-driven generator. The anti-lock screw mechanism comprises a fixing part, a screw barrel and a locking pin, wherein the fixing part is provided with a hollow movement space which penetrates through the fixing part; the screw barrel is arranged at one end of the movement space of the fixing part, and can rotate relative to the fixing part; the locking pin comprises a first end face and a screw fixedly arranged on the first end face; the axis of the screw is perpendicular to the first end face; the screw barrel comprises a second end face which is perpendicular to the axis of a hole and opposite to the first end face; the screw is in threaded connection with the interior of the screw hole of the screw barrel, and drives the locking pin to reciprocally move in the movement space under the action of rotating movement of the screw barrel; a buffer device is arranged between the first and second end faces. The anti-lock screw mechanism has the advantages that the anti-lock screw mechanism is reasonable in design and simple in structure; rigid collision between the locking pin and the screw barrel can be avoided, so that thread lock is prevented.

Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to an anti-locking screw mechanism and a locking device for a rotating part of a wind power generator. Background technique [0002] During hoisting, commissioning and maintenance of wind turbines, the rotating parts need to be locked. In order to achieve locking, the lock pin on the fixed part of the generator (such as the stator) is generally pushed into the hole of the rotating part (such as the rotor). The locking or unlocking function can be realized by means of screw transmission. [0003] The rotary body rotates around a certain rotation center relative to the fixed part. One or more holes are distributed in the circumferential direction of the rotating body. By rotating the screw sleeve, the lock pin can be inserted into the hole of the revolving body to restrict the rotation of the revolving body to achieve locking, and the lock pin can be pulled out from t...

AI Technical Summary

Problems solved by technology

During the unlocking process, the end surface of the lock pin will contact the end surface of the screw sleeve. Due to the inertia of the rotating screw sleeve, the contact surface will rigidly collide, and the screw sleeve will stop rotating instantly, which will easily cause the thread to be stuck and locked. It is difficult to use after locking. The screw sleeve rotates. Generally, when such a situation occurs, it will be loosened by tapping the screw sleeve, but this may cause damage to the thread, and it will be more difficult to rotate the screw sleeve
