Programmable intelligent rail polishing vehicle

Abstract

The invention discloses a programmable intelligent rail polishing vehicle which comprises a frame and a CNC control mechanism arranged on the frame. The frame is erected on a rail through rail runningwheels arranged at four corners of the bottom, a running driving servo motor is further arranged on the frame, and the running driving servo motor is in driving connection with one of the two rail running wheels on the right side of the bottom of the frame. The CNC control mechanism comprises an adjusting mechanism, a polishing mechanism and a span automatic adjusting mechanism. According to theprogrammable intelligent rail polishing vehicle, the adjusting precision is high, no deviation is caused after position adjustment, the polishing quality is good, performance is stable, modular designis adopted, detachable connection is extensively adopted, disassembly and assembly can be rapidly achieved, rapid rail entering and exiting can be achieved due to the rapid assembly and assembly function, it is effectively ensured that rail traffic is smooth in case of emergency, potential safety hazards are completely eradicated, meanwhile, and adjustment can be rapidly carried out when the railspan is changed.

Description

technical field [0001] The invention relates to the field of track maintenance equipment, in particular to a programmable intelligent track grinding vehicle. Background technique [0002] With the rapid development of China's railways and subways, the mileage of the track is getting longer and longer, and there are more and more problems caused by track rolling and long-term running of the train, such as unevenness, track surface spots, small track defects and track waveform wear. exposed. These scratches and abrasions lead to greater impact on the wheels and rails of the train, posing a great safety hazard. In order to eliminate similar scratches and extremely short-wavelength corrugated wear on the top and side surfaces of the rail, in the prior art, grinding is generally used for repairing. Re-grinding the top and side of the rail can reduce the impact force of the wheel and rail when the train is running, thereby reducing the vibration generated when the train is runni...

Problems solved by technology

[0004] 1. It is bulky and heavy, and it cannot realize fast up and down tracks, and it is difficult to ensure smooth rail traffic in emergency situations;

[0005] 2. The angle of grinding accuracy and the operation are complicated;

[0006] 3. When the grinding equipment is running on the track, there will be error changes in the span between the tracks. The running wheel of the existing grinding e
