Overhaul and transport vehicle and overhauling and transport method

Abstract

The invention discloses an overhaul and transport vehicle and method for a water-feeding pump motor. The overhaul and transport vehicle comprises a vehicle body (1) and universal wheels (2). The universal wheels (2) are arranged at the bottom of the vehicle body (1). The sliding wheel set (2) is fixedly arranged on the top of the vehicle body (1) and provided with a sliding plate which can slide on the sliding wheel set (2). The overhaul and transport method comprises the following steps: parking the overhaul and transport vehicle on one side of the water-feeding pump motor, making the surface of the overhaul and transport vehicle flush with the surface of the water-feeding pump motor mounting base, disassembling and ascending the water-feeding pump motor, arranging the sliding wheel set (2) and the sliding plate on the surface of the overhaul and transport vehicle and the surface of the water-feeding pump motor mounting base respectively, descending the water-feeding pump motor on the sliding plate, moving the water-feeding pump motor onto the overhaul and transport vehicle by enabling the sliding plate to slide, mounting and fixing, and finally transporting the water-feeding pump motor through the overhaul and transport vehicle and overhauling the water-feeding pump motor.

Description

technical field [0001] The invention relates to a transport trolley, in particular to an overhaul transport trolley for transporting a large feedwater pump motor, and a maintenance and transportation method for using the overhaul transport trolley to transport the feedwater pump motor out of a narrow factory building. Background technique [0002] Feed water pump motors are usually limited by the design of the plant and the narrowness of the maintenance site, making it difficult to carry out electric maintenance work normally. For example, after a motor failure, equipment repairs cannot be carried out immediately on the plant site. Especially after the motor is burned out, it is difficult to transport the motor weighing 40 to 50 tons out of the maintenance site by conventional methods, and it is also impossible to directly pump and wear the rotor at the installation position of the equipment (weighing more than ten tons and nearly three meters long). maintenance work, thus ...

Problems solved by technology

[0002] Feed water pump motors are usually limited by the design of the workshop and the narrowness of the maintenance site, making it difficult to carry out electric maintenance work normally

For example, after a motor failure, equipment repairs cannot be carried out immediately on the plant site

Especially after the motor is burned out, it is difficult to transport the motor weighing 40 to 50 tons out of the maintenance site by conventional methods, and it is also impossible to directly pump and wear the rotor at the installation position of the equipment (weighing more than ten tons and nearly three meters long). maintenance work, thus seriously affecting the progress and quality of equipment maintenance

The reason why it is difficult to directly inspect and repair on site and to transport the factory is attributed to the small space of the installation site of the feed water pump motor, and the design does not consider the maintenance space of the pumping and penetrating rotor, or the inspection space cannot meet the standards for the feed water pump motor maintenance requirements

Moreover, the transportation channel on the production site is relatively narrow compared with the size of the feed water pump motor, and it is difficult to use the hoisting device in the factory building to transport
