Embodiment 1

[0016] 1) An operator uses the manual pump 12 of the hydraulic system to pressurize the system, only need to pressurize to 100bar, and at the same time uses the manual function of valve I9 ​​that can be self-locked, so that the valve I9 ​​is ​​in the open state;

[0017] 2) Another operator uses the high-speed shaft brake disc 6 to steer to any steering wheel;

[0018] 3) Observe the rotation of the main shaft lock disc, when the appropriate lock hole 1 on the main shaft lock disc 2 (the lock hole 1 is evenly arranged on the main shaft lock disc 2 along the circumferential direction, there are 12 in total) fast to the corresponding position of the lock pin , that is, when there is a difference of half to a position of lock hole 1 (because the spindle lock can be seen from the position of the hydraulic station, the position of lock hole 1 can be roughly judged, and no additional personnel are required to observe the lock pin and lock hole 1 corresponding situation), press the m...

Embodiment 2

[0021] 1) An operator uses the manual pump 12 of the hydraulic system to pressurize the system, and only needs to pressurize to 105bar, and at the same time uses the manual function of valve I9 ​​that can self-lock, so that valve I9 ​​is ​​in the open state;

[0022] 2) Another operator uses the high-speed shaft brake disc 6 to steer to any steering wheel;

[0023] 3) Observe the rotation of the main shaft lock disc. When the appropriate lock hole 1 on the main shaft lock disc 2 is quickly rotated to the corresponding position of the lock pin, that is, the difference is half to one lock hole position (because standing at the position of the hydraulic station, you can see To the main shaft lock, you can roughly judge the position of the lock hole, and there is no need for other personnel to observe the corresponding situation between the lock pin and the lock hole 1), press the manual operation handle of the reversing valve II10, and the lock pin will extend. When the lock hole...

Embodiment 3

[0026] 1) An operator uses the manual pump 12 of the hydraulic system to pressurize the system, only need to pressurize to 110bar, and at the same time uses the manual function of valve I9 ​​that can be self-locked, so that the valve I9 ​​is ​​in the open state;

[0027] 2) Another operator uses the high-speed shaft brake disc 6 to steer to any steering wheel;

[0028] 3) Observe the rotation of the main shaft lock disc. When the appropriate lock hole 1 on the main shaft lock disc 2 is quickly rotated to the corresponding position of the lock pin, that is, the difference is half to one lock hole position (because standing at the position of the hydraulic station, you can see To the main shaft lock, you can roughly judge the position of the lock hole, and there is no need for other personnel to observe the corresponding situation between the lock pin and the lock hole 1), press the manual operation handle of the reversing valve II10, and the lock pin will extend. When the lock ...

Abstract

The invention relates to a method for locking a spindle lock of a wind power generator set. The method is simple, so that only two persons can operate and finish the work of locking the spindle lock; and the labor efficiency is improved effectively. The method comprises the following steps of: 1) only pressing a system to 100-110 bars by using a manual hydraulic pump of a hydraulic system; 2) barring by a barring worker towards one direction; and 3) when a proper spindle lock hole on a spindle lock disc is turned to a position corresponding to a lock pin, namely only half or one lock hole position is differed, pressing down a manual operation handle of a reversing valve so that the spindle lock pin can be inserted into the lock hole successfully.

Description

technical field [0001] The invention relates to a method for locking a main shaft lock of a wind turbine. Background technique [0002] The aeroMaster1.5MW wind turbine is designed as a hydraulically driven main shaft lock solution. Such as figure 1 Shown: According to the design requirements, during the normal operation stage of the wind turbine, the hydraulic system of the unit operates automatically through the main control system in the control cabinet of the engine room, and the electric pump is used to pressurize the system, so that the pressure of the hydraulic system is controlled within the range of 140-160bar; When locking the main shaft lock 4 in order to fix the wind wheel, the operator must use the high-speed shaft brake disc 6 to perform manual barring, so that when the proper main shaft lock hole 1 is aligned with the lock pin, the high-speed shaft brake disc 6 must be stabilized first. To fix the main shaft 3 and the main shaft lock plate 2; and then use th...
