Full-section derusting machine of steel rail and derusting method

Abstract

The invention discloses a full-section derusting machine of a steel rail. The full-section derusting machine comprises a base, a mounting base arranged on the base, a laser derusting system arranged on the mounting base, wherein the laser derusting system comprises a laser head with a laser beam emitting function and a driving device capable of driving the laser head to move, the laser head is arranged on the driving device, and the laser head can directly face the rail top surface, a rail bottom surface or a rail section of the steel rail after moving, and further comprises a clamp system which is arranged on one side of the laser derusting system and can clamp and fix the steel rail; and meanwhile, the invention also provides a derusting method of the derusting machine. According to the derusting machine and the derusting method, no dust pollution is generated in the operation process, the rust removal is thorough, the phenomenon that a machined part is scrapped due to the fact that the rust removal depth is too deep is avoided, the device is simple in structure, high in reliability and convenient to rust.

Description

technical field [0001] The invention belongs to rail production equipment, in particular to a rail full-section derusting machine and a derusting method. Background technique [0002] In order to obtain the steel rails needed for the construction of railways on the construction site, the following steps are generally required: the short rails are produced by the steel factory, and the short rails need to be welded to the long rails before they arrive at the construction site. The short track produced by the steel mill will rust due to long-term storage, making it impossible to weld. Generally, it is necessary to derust both ends of the short track before welding. Weld the two short tracks to the long track. The welding process is completed in the production workshop, and it will be transported to the construction site after the welding is completed. [0003] So far, at the production end of the rail, the derusting at both ends of the rail is carried out by using tools such...

Problems solved by technology

[0007] 3. The surface of the rail that needs to be derusted includes three parts: the top surface of the rail, the bottom surface of the rail and the cross section of the rail, and the method of removing the base material is used for machining, and the processing depth of these three parts needs to be strictly controlled. It will cause the equipment system to be complicated and the reliability of the equipment to be poor
