An automatic grinding system for maintenance of high speed rail, power train and metro rail

Abstract

A method and apparatus for high-speed rail, Automatic grinding system for rail maintenance on power cars and metro lines, include a polishing device, the polishing device comprises a mounting plate, amounting base for adjusting the cylinder and the grinding mechanism, A left and right end of that mounting plate are symmetrically mount with mounting bases, A regulating cylinder is installed in themounting base, the adjusting cylinder is two-way telescopic structure, A grinding mechanism is installed at the front and rear ends of the adjusting cylinder, The grinding mechanism comprises a workframe, a No. 1 fixed plate, a No. 2 fixed plate, a rotating shaft, a rotating grinding wheel, a rotating gear, a transition gear, a rotating electric machine, a fixed seat, an adjusting electric pushrod, an adjusting frame, a No. 1 working plate, a No. 2 working plate, a rotating shaft, a rotating grinding wheel, a rotating gear, a connecting gear, a rotating electric machine, an auxiliary springand a guide plate. The invention can solve the problems of high labor cost, low working efficiency, inconvenient adjustment, small use range and the like existing in the existing rail maintenance andpolishing process, and can realize the function of automatic polishing of the rail.

Description

technical field [0001] The invention relates to the field of rail maintenance equipment, in particular to an automatic grinding system for rail maintenance of high-speed railways, bullet trains and subways. Background technique [0002] Locomotives such as high-speed trains, high-speed trains, and subways do not have steering wheels. Drivers do not need to operate the steering wheel, and the vehicles are completely guided by the rails. Therefore, the rails carry huge pressure and impact from the wheels. Under extremely complex working conditions, rails will inevitably produce various damages, including defects in the smelting process, and damages in the process of transportation, construction and use. In order to eliminate the bad marks on the surface of the rail, prevent the further development of these defects, and improve the service life of the rail, it is often necessary to maintain the rail. One of the maintenance tasks is grinding. At present, grinding wheel equipment...

AI Technical Summary

Problems solved by technology

[0003] In order to make up for the deficiencies of the prior art, the present invention provides an automatic grinding system for rail maintenance of high-speed railways, bullet trains and subways, which can solve the problems of high labor cost, low work efficiency, inconvenient adjustment and problems existing in the existing rail maintenance and grinding process. It can realize the function of automatic grinding of rails due to the small range of use, and has the advantages of low labor cost, high work efficiency, flexible adjustment and wide application range, etc.
