Abstract

The invention provides a grinding device for a steel rail high-speed grinding train. The grinding device includes a grinding trolley, a rotary bracket arranged on the grinding trolley and a grinding wheel group. Guiding wheels are arranged on the lower portion of the grinding trolley. Automatic rotary devices are arranged at two ends of the rotary bracket. Automatic rotary devices are connected with a grinding trolley frame through a vertical cylinder. One end of a guiding column which is used for guiding up and down of the rotary bracket is arranged on an upper crossbeam of the grinding trolley frame, and the other end is arranged on a lower crossbeam of the grinding trolley frame. The grinding device for the steel rail high-speed grinding train has the advantages of being high in grinding efficiency and enabling the steel rail high-speed grinding train to be utilized in a railway operation system; opening skylight points which are additionally opened is unnecessary and economic benefits of railway transportation are effectively improved.

Description

technical field [0001] The invention relates to a rail grinding device. Background technique [0002] With the rapid development of my country's railway transportation industry, the train weight and traffic density of the main trunk lines are increasing, especially the opening of heavy-duty transportation and high-speed lines. , side grinding of small radius curves and other rail damages are very prominent. In view of these damages, the use of rail grinding trains to grind and maintain the online rails can not only prolong the service life of the rails, but also improve the quality of the lines, improve the running quality of the trains, and ensure the safe operation of the trains. [0003] At present, the rail grinding strategies adopted in our country are repair grinding, which is usually carried out after the surface defects of the rail are formed; the main rail grinding methods used are sliding shoe grinding, grinding wheel grinding and milling grinding. The work must b...
