Abstract

The invention provides a locking device for a locking servomotor. The locking device comprises a locking hydraulic cylinder, a locking flashboard and a guide block. A front end cover of the locking hydraulic cylinder is fixedly connected to a servomotor cylinder cover, the locking flashboard is provided with a T-shaped groove, the protruded tail end of a piston rod of the locking hydraulic cylinder is provided with a lock head matched with the T-shaped groove, the guide block is fixedly connected to the servomotor cylinder cover, and the locking flashboard is slidably connected with the guide block. When the locking device is used, the lock head is inserted in the T-shaped groove which is formed in the locking flashboard and matched with the lock head, and accordingly the piston rod of the locking hydraulic cylinder is connected with the locking flashboard; the problem that the locking flashboard is difficult to install in a small space is solved, and the device is convenient to operate and greatly improves installing efficiency.

Description

technical field [0001] The invention relates to the field of components of guide vane hydroelectric generator sets, in particular to a locking device for locking a servomotor. Background technique [0002] The locking device of the guide vane servomotor of the turbine is to lock the servomotor piston in the fully closed position when the unit is shut down and the guide vane is closed, which is one of the technical measures to ensure the safe operation of the unit. refer to Figure 6 As shown, the conventional servomotor locking device fixedly connects the locking hydraulic cylinder piston rod 14 and the locking gate 11 through the connecting block 16, which is relatively convenient to process, but has obvious disadvantages, that is, during installation, due to The operation space is relatively small, and it is very inconvenient when the locking hydraulic cylinder piston rod 14 is connected to the locking ram 11 through the connecting block 16. While consuming a lot of manpow...
