Description

A tool for removing rubber nodes of a traction motor

technical field

The utility model belongs to the field of traction motor manufacture and maintenance, in particular to a tool for disassembling rubber nodes of a traction motor.

Background technique

The disassembly of the traction motor rubber joints of domestic and foreign bullet trains generally uses a larger traction motor rubber joint disassembly tool. The weight of the tooling is very heavy, and the weight of the disassembled pressure plate is about 40kg. It is a single part and can be installed and removed manually. The size of the tooling is large, and a special wooden pallet or workbench with an area of about 1.2 square meters is required to place the tooling. Due to the heavy weight of the rubber node tooling, a special cantilever crane is required to hang the disassembly tooling to realize the disassembly operation of the rubber node, which is very troublesome. As for the rubber node under the motor, due to its positional relationship, large-scale disassembly tooling cannot be installed. The motor needs to be hoisted to a special disassembly workbench before the rubber node under the motor can be disassembled. Due to the heavy weight of the dismantling pressure plate, it is often necessary to move it up and down. In order to reduce the operation time, generally only male employees can directly move it by hand to install and disassemble the dismantling pressure plate. The labor intensity is high and it is not safe. There are potential safety hazards, and it is easy to injure the operating staff. Therefore, the current rubber node disassembly method has the disadvantages of large investment in equipment and tooling, inconvenient operation, long disassembly time, low production efficiency, high labor intensity of employees, and low production safety.
