Width-adjustable dynamic process bogie for bullet train

Abstract

A width-adjustable dynamic process bogie for a bullet train comprises a base plate, a driving device arranged at the bottom of the base plate, an accumulator battery arranged on the base plate and used for providing a power source for the driving device, driving wheels driven by the driving device and arranged below the front end of the base plate, and driven wheels arranged below the rear end of the base plate and connected with the driving wheels through a transmission structure, wherein a first longeron and a second longeron are symmetrically arranged on the two sides of the base plate and positioned above the driving wheels and the driven wheels; a crossbeam is arranged on the first longeron and the second longeron in a supporting manner; a first support device and a second support device which can move along the crossbeam and used for supporting an engine box are symmetrically arranged at the upper parts of the two ends of the crossbeam; a side bearing device used for adjusting the height of the crossbeam is arranged on each of the outer sides of the first longeron and the second longeron and positioned in the lower side of each of the two ends of the crossbeam. The width-adjustable dynamic process bogie shortens the maintenance time, simplifies the operation steps and ensures a real sense of production-line operation of maintenance of the bullet train.

Description

technical field [0001] The invention relates to a process bogie. In particular, the utility model relates to a power train bogie with adjustable width. Background technique [0002] The process bogie is used to replace the high-speed bogie of the EMU during the disassembly and overhaul of various types of EMU car bodies. Under the process state, it supports the car body in each maintenance process position for flow operation. It also has the performance of curve passing and turnout passing performance. The car body moves between the track and the warehouse, and it is a special tooling equipment for completing various maintenance tasks of the high-speed bogie and car body. [0003] There are mainly CRH1, CRH2, CRH3, and CRH5 car bodies in China. The four models have different sizes, dead weights, and spans of support points. As a result, the maintenance tooling equipment cannot be compatible with the requirements of multiple models, and the maintenance time Long, unable to ...
