[0010] 3. "Fan fan and its wind wheel locking device" (patent number: 201110159766.0) provides a fan and its wind wheel locking device. By adjusting the eccentricity between the lock body and the lock pin, the lock pin and the lock pin are solved. The problem of the centering of the stop hole, but it does not solve the problem of the locking pin stuck due to the increase of friction caused by corrosion

Embodiment Construction

[0036] The present invention will be further described below in conjunction with the drawings. Such as Figure 3-4 As shown, a wind wheel locking mechanism of a wind power generator includes a locking pin 31, a piston rod 32, an oil cylinder end cover 33, a connecting flange 34, a locking nut 35, a thrust bearing 38 and a transmission nut 39.

[0037] The locking pin 31 has a tapered left end and a cylindrical right end. A round hole is opened on the right end surface as a hydraulic cylinder, and threads are machined near the right end surface of the round hole; the piston rod 32 is made of steel with a stepped cylindrical structure. One piece, the cross-section along the center line is T-shaped, the left end cylinder is installed in the circular hole of the locking pin 31 as a piston, and the left end diameter is larger than the right end diameter; the cylinder end cover 33 is a hollow cylindrical structure with an outer cylinder The surface is machined with threads, and is con...

Abstract

The invention discloses a wind wheel locking mechanism of a wind driven generator. The wind wheel locking mechanism comprises a locking pin, a piston rod, an oil cylinder end cover, a connecting flange, a locking nut, a thrust bearing and a transmission nut. The piston rod, the thrust bearing, the transmission nut and the locking nut jointly form a manual unlocking mechanism. The manual unlocking mechanism is adopted and can be independently used or be combined with a hydraulic system for use, and the blockage problem of the locking pin is solved. The wind wheel locking mechanism is the same as a most-frequently-used wind wheel locking mechanism connector used for an existing wind driven generator set and can be universal on the premise that a host interface is not changed. The wind wheel locking mechanism is used for emergency during power failure through manual operation, the wind wheel locking mechanism can be combined with the hydraulic system for use so that pressure of the hydraulic system can be reduced, bad influences caused by over-high pressure of the hydraulic system on hydraulic system elements and oil cylinder sealing are avoided, the service life of the hydraulic system can be effectively prolonged, and energy waste is avoided. Operation achieved through a jack is replaced with manual operation, and operation is easy and convenient.

Description

Technical field [0001] The invention relates to the field of braking systems for wind power generation equipment, in particular to a wind wheel locking mechanism of a wind power generator. Background technique [0002] The wind turbine locking mechanism is an important safety device for the maintenance personnel of the wind turbine to lock the wind turbine. It is only used during the maintenance of the wind turbine. When the wind turbine is overhauled, the wind turbine and the main shaft are generally stopped by the braking system. Then the locking pin of the driving wind wheel locking mechanism moves forward along the cylindrical pin hole, so that the tapered part of the front end of the locking pin extends into the tapered pin hole of the wind wheel locking disc to lock the wind wheel to ensure the safety of personnel and equipment . [0003] The rotor locking mechanism of the existing megawatt wind turbines is generally hydraulically driven, such as Figure 1-2 As shown, the win...
