A point rail grinding device for track maintenance vehicles

Abstract

The invention discloses a switch rail polishing device for a rail maintenance vehicle. The switch rail polishing device for the rail maintenance vehicle comprises a transverse moving mechanism, mounting structures and polishing mechanisms. A sliding plate of the transverse moving mechanism is provided with the mounting structures; the polishing mechanism is mounted on each mounting structure; twobelt wheel axles are rotatably mounted on each mounting structure and the two belt wheel axles are connected to an output shaft of a driving motor through a belt transmission mechanism; a rotating armI and a rotating arm II are rotatably mounted below each mounting structure; one belt wheel axle penetrates from the axe of the rotating arm I while the other belt wheel axle penetrates from the axleof the rotating arm II. By arranging a tension spring and the rotating arms, an effect of auto-adapting width change of a railhead of a switch rail in a segment of width change of the railhead as therotating arms rotate is achieved. The positions of the polishing mechanisms are adjusted by the transverse moving mechanism according to change of the switch rail deviated from a base rail, so that the switch rail of the change part of the railhead is polished and derusted.

Description

technical field [0001] The invention belongs to the field of track maintenance, and in particular relates to a sharp rail grinding device for a track maintenance vehicle. Background technique [0002] In the field of rails, I-shaped rails are widely used, but after long-term use, the rails will produce a certain amount of corrosion. If a section of rails is not used for a period of time, it will be severely corroded and needs to be polished and derusted, otherwise there will be safety hazards. Conventional grinding vehicles are divided into large grinding trains and small track maintenance vehicles. Large grinding trains are mainly used for grinding and maintenance of the entire line, not for rust removal. Due to the high cost and low frequency of use, they are rarely used for maintenance in local areas. The small track maintenance vehicle is driven by a battery or a diesel engine and is used to maintain the rails in a local area. It can be equipped with a variety of mainte...
