Embodiment 1

[0027] Such as figure 1 As shown, this embodiment provides a circulating water pump motor maintenance device for nuclear power plants, including a body 1, which is composed of an upper base 2, a lower base plate 4 and a vertical plate 3, and the upper base 2 and the lower base plate 4 are circular. The blue plate, the body 1 is integrally formed into a circular platform structure. The upper and lower ends of the vertical plate 3 are fixedly connected with the upper base 2 and the lower base plate 4 respectively. The center of the upper base 2 is provided with a through hole for placing the motor, and the outer contour is provided with a hole for aligning the axis of the motor with the center of the through hole. The boss seam 5 of the line and the bolt hole 6 connected with the motor base. In addition, it also includes a protective gasket for placing between the upper base 2 and the motor. The protective gasket can be a nylon gasket made of a polytetrafluoroethylene plate wit...

Embodiment 2

[0029] still reference figure 1 , in this embodiment, the side of the body 1 is provided with an inspection channel 8, which is set up so that maintenance personnel can easily access the inspection device for circulating water pump motors used in nuclear power plants, and perform maintenance on the lower part of the motor. Other structures and connections are the same as in Embodiment 1.

[0030] Example: 3:

[0031] still reference figure 1 , in this embodiment, it also includes lifting lugs, and the lifting lugs are bolted to the upper base 2 through the lifting lug connection holes 7 . Such arrangement facilitates the handling and movement of the circulating water pump motor maintenance device for nuclear power plants. Other structures and connections are the same as in Embodiment 1.

Embodiment 4

[0033] In this embodiment, lifting lugs are also included, and the lifting lugs are fixedly connected with the upper base 2 by welding. Other structures and connections are the same as in Embodiment 1.

Abstract

The invention relates to a maintenance device for a circulating water pump motor used in a nuclear power plant, which includes a body, the body is composed of an upper base, a lower bottom plate and a vertical plate, and the upper and lower ends of the vertical plate are respectively connected to the upper base, the lower The bottom plate is fixedly connected; the center of the upper base is provided with a through hole for placing the motor. Compared with the prior art, the invention maintains the vertical heavy-duty motor, and has the advantages of firm structure, stable center of gravity, safe maintenance, and convenient disassembly and transportation of the motor coupling and the lower guide bearing chamber of the motor.

Description

technical field [0001] The invention belongs to the technical field of motor maintenance, and in particular relates to a motor maintenance device for circulating water pumps used in nuclear power plants. Background technique [0002] At present, the motors of circulating water pumps in nuclear power plants are mostly vertical heavy-duty (up to tens of tons) structural forms. During maintenance, a bracket is needed to complete the placement and maintenance of the motors. Such devices are not provided when the motors leave the factory and are installed. Other power stations have used temporary brackets made of steel such as channel steel to complete motor maintenance. This temporary bracket has the defects of insufficient structural strength and non-centralized center of gravity, which makes maintenance work in a dangerous environment. Moreover, this temporary bracket is not convenient for motors. Removal and transport of coupling and motor down guide bearing housing. [0003...
