Problems solved by technology

In the process of bogie size measurement and adjustment, in the past, several positioning jib piers were installed on the cast iron platform, and large-scale hoisting equipment was used to lift the bogie and place it on the axle box piers, and the wheels were locked by screws. Car-assisted completion, positioning and locking, etc. require manual assistance, which increases the difficulty of the operation and prolongs the operation time

Abstract

The invention relates to an adjusting device for motor train unit overhauling, in particular to a device for measuring and adjusting the bogie size of a motor train unit. The device for measuring and adjusting the bogie size of the motor train unit comprises a power mechanism, a transmission mechanism, a fixed platform, a measuring platform and a lifting mechanism, wherein the fixed platform is of a hollow structure, the measuring platform is embedded into the hollow structure of the fixed platform and in slide fit with the fixed platform, the fixed platform and the measuring platform are respectively provided with two parallel rails, a lifting column in the lifting mechanism is in slide fit with a positioning hole in the fixed platform, the bottom end of the lifting column is connected with a lifting supporting frame, a wheel positioning mechanism is arranged on the lifting column, and the lifting supporting frame is connected with the transmission mechanism. Compared with the prior art, the device for measuring and adjusting the bogie size of the motor train unit has the advantages that wheel positioning, positioning rotating arm supporting and measuring platform lifting can be sequentially achieved through the lifting mechanism, and the operation field can be saved.

Description

technical field [0001] The invention relates to an adjustment device for the inspection and maintenance of an EMU, in particular to an equipment for measuring and adjusting the size of the bogie of an EMU. Background technique [0002] The bogie is one of the most important components on the EMU vehicle, which directly affects the safety and stability of the EMU operation. During the inspection and maintenance process of CRH2 EMUs, after the assembly of the bogie components, it is necessary to measure and adjust the wheelbase of the bogie, the wheel diagonal, the distance between the wheels and the frame, etc., so as to ensure the normal operation of the EMU. [0003] When measuring and adjusting the size of the bogie of the type EMU, in order to facilitate the operation of personnel, the bogie needs to be higher than the ground at a certain height, and at the same time, the wheel positioning and locking, the supporting and positioning boom, and the accuracy of the measuring...
