Railway track maintenance rust mark polishing device

Abstract

The invention discloses a railway track maintenance rust mark polishing device, and relates to the technical field of track 1 polishing. The device comprises a walking frame erected on a track, a reciprocating device fixed to the top of the walking frame, a power device fixed to the bottom of the end, opposite to the reciprocating device, of the walking frame, a movable groove formed in the center of the top face of the walking frame and a grinding device movably connected into the movable groove. The grinding device comprises a cross beam and grinding pieces located below the cross beam and clamped on the two sides of the track, movable rods are fixedly connected to two side plates of the movable groove in parallel, the cross beam is movably connected to the movable rods in a sleeving mode, and adjusting grooves are formed in the two ends of the movable cross beam. According to the railway track maintenance rust mark polishing device, through cooperative arrangement of the fixing rod and the polishing piece, in the using process of the device, the fixing rod can be used for clamping the polishing piece and a track and completely attaching the polishing piece to the track, comprehensive polishing can be conducted on the track, and polishing dead corners are avoided.

Description

technical field [0001] The invention relates to the technical field of track grinding, in particular to a rust grinding device for railway track maintenance. Background technique [0002] Rail grinding is an important part of line repair work and an effective means of rail disease prevention and treatment. Grinding can improve the wheel-rail contact relationship, prevent and delay the occurrence of rail defects such as contact fatigue, abrasion, wave wear (referred to as corrugation), repair or reduce rail surface defects, reduce the risk of rail fracture, and prolong the service life and maintenance of rail equipment. Period, the rail surface defects that can be solved by grinding mainly include fatigue cracks, peeling off blocks, corrugation, abrasions, scabs, fat edges, uneven wear, poor light bands, etc. The grinding equipment for lines and turnout rails used in my country mainly There are rail grinding trains, turnout grinding vehicles, rail milling and grinding vehicles...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a kind of railway track maintenance rust grinding device, to solve the problem that the track derusting and grinding device proposed in the above background technology is pushed to the model for grinding through the wheel-shaped grinding head, but the grinding head cannot completely cover the track. There will be dead corners during grinding, and complete grinding cannot be carried out. In order to complete the grinding, there are usually multiple grinding heads for grinding, resulting in high cost, and the grinding heads are fixedly installed. After wear, the contact with the track is reduced, which affects the grinding effect The problem
