Special bracket for overhauling station water pump motor of nuclear power station

Abstract

The invention relates to a special bracket for overhauling a station water pump motor of a nuclear power station, and the bracket is used for providing a stable support for motor maintenance. The bracket comprises a support body (1) and a nylon gasket; the support body (1) is fastened on the flat ground through foundation bolts, and the nylon gasket is fastened on the upper surface of the supportbody (1) through screws; the motor flange is locked with the upper surface of the support body (1) through a fastening bolt, the support body (1) is of a hollow structure, and the support body (1) isprovided with an equipment channel hole (6) used for transporting out a motor coupler detached from a motor during maintenance. Compared with the prior art, the motor coupler dismounting device has the advantages that the motor maintenance stability is improved, the dismounted motor coupler can be safely and conveniently transported out, and the space is saved.

Description

technical field [0001] The invention relates to the technical field of inspection and maintenance of plant water pumps, in particular to a special support for maintenance of plant water pump motors in nuclear power plants. Background technique [0002] In the dismantling inspection and maintenance of the plant water pump and motor, it involves placing the plant water pump motor and repairing the motor. In previous inspections, potholes or temporary brackets were usually used to place factory motors to complete the inspection of the motors. This method has many restrictions and dangers. For example, when the factory water pump motor is placed on the pits, it is easy to cause disassembly. After the motor coupling, the problem that the motor coupling cannot be transported out, and it is easy to make the work of personnel limited by space, etc., and if the plant water pump motor is placed on a temporary support, it is easy to cause the center of gravity of the plant water pump m...

AI Technical Summary

Problems solved by technology

In previous inspections, potholes or temporary brackets were usually used to place factory motors to complete the inspection of the motors. This method has many restrictions and dangers. For example, when the factory water pump motor is placed on the pits, it is easy to cause disassembly. After the motor coupling, the problem that the motor coupling cannot be transported out, and it is easy to make the work of personnel limited by space, etc., and if the plant water pump motor is placed on a temporary support, it is easy to cause the center of gravity of the plant water pump motor to be unstable , there is a danger of collapse, and it is not conducive to the maintenance of equipment, etc.
