Abstract

The invention provides a compact abrasive belt type steel rail grinding device. The abrasive belt tensioning device comprises an abrasive belt wheel train transmission structure, and a transverse movement structure, a vertical movement structure, a deflection movement structure, a locking mechanism and an abrasive belt tensioning mechanism which are connected with the abrasive belt wheel train transmission structure. The abrasive belt wheel train structure drives a driving wheel to move through a driving motor and a triangular belt wheel transmission mechanism, and the driving wheel drives anabrasive belt to conduct grinding operation. The vertical movement structure drives the abrasive belt wheel train structure to move vertically through bearing of the vertical guide rail, the verticalsliding block and the vertical support. The deflection motion structure drives the abrasive belt wheel train structure to perform deflection motion through a deflection motor and a rack; the transverse movement structure drives the abrasive belt wheel train structure to transversely move through a transverse electric lead screw and a transverse motor. The compactness of the grinding unit is achieved, the deflection angle of the grinding unit towards the inner side of the steel rail is increased, the longitudinal space of the grinding unit along the steel rail is effectively utilized, and the length of a grinding train is shortened on the premise that the number of grinding heads is the same.

Description

technical field [0001] The invention relates to the technical field of rail grinding, in particular to a compact abrasive belt type rail grinding device. Background technique [0002] With the continuous development of my country's railway industry, the weight of trains and traffic density are on the rise, and the problem of rail diseases has become increasingly prominent. If these rail defects cannot be eliminated in time, it will cause traffic safety problems, pose a threat to goods, and even cause casualties. The use of rail grinding technology for line maintenance has become the consensus of track maintenance at home and abroad. It can not only eliminate these hidden dangers of rails, but also significantly prolong the life of rails, improve line quality, and ensure the safe operation of trains. [0003] At present, grinding wheels and milling cutters are mainly used as tools for rail grinding. Due to the limitations of the performance of the grinding tools and the grin...
