Embodiment Construction

[0019] figure 1 Among them, the rail high-speed grinding train includes a power tractor 1, a grinding operation vehicle 2, and grinding devices 3 installed on both sides of the grinding operation vehicle 2. Grinding device 3 can be used in conjunction with eight sets, and is symmetrically installed on the left and right sides of grinding operation vehicle 2.

[0020] figure 2 Among them, the grinding device includes a grinding trolley 4, a turret 5 mounted on the grinding trolley 4, and a grinding wheel set mounted on the turret 5. Each group of grinding wheels is a row of 12 grinding wheels 6; the grinding wheels 6 are arranged in groups at a certain angle (30°-150°) inclined to the direction of the train; the 12 grinding wheels 6 are divided into three groups, and the middle 6 are ground The grinding wheel is a group, the 3 grinding wheels at the left end are a group, and the 3 grinding wheels at the right end are a group. The axis line of the 6 grinding wheels in the mi...

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 main trunk lines are increasing, especially the opening of heavy-duty transportation and high-speed lines. Rail damage such as side grinding of small radius curves is very prominent. In response to 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 line, improve the quality of train operation, and ensure the safety of train operation. [0003] At present, the rail grinding strategies adopted in my country are restorative grinding, usually after the surface defects of the rail are formed; the rail grinding methods mainly include sliding shoe grinding, grinding wheel grinding and milling. The work must be carried out with the sunroof open. H...
