MAINTENANCE APPARATUS FOR GUIDE VANE SERVO MOTOR

摘要

The present invention relates to a maintenance apparatus for a guide vane servomotor which can shorten maintenance time, improve the degree of precision and reliability, and prevent safety accidents caused by handling heavy objects when a guide vane servomotor in a pumped storage power plant is required to be disassembled or assembled for maintenance thereof. The maintenance apparatus for a guide vane servomotor comprises the following: an I-shaped steel member which is horizontally installed above the guide vane servomotor to be a predetermined distance away from the guide vane servomotor; a trolley member which is installed to be able to move horizontally with an upper portion thereof being inserted into the I-shaped steel member and a lower portion thereof being combined with the body of the guide vane servomotor; and an auxiliary trolley member which is installed at the front of the trolley member to be able to move horizontally with an upper portion thereof inserted into the I-shaped steel member and a lower portion thereof combined with the front end of the guide vane servomotor.
