Problems solved by technology

[0004] At present, methods such as manual grinding and track replacement are generally used. Not only the maintenance efficiency is low, the cost is high, and the waste is large, but also seriously affects the operation of the train.
The grinding system under development does not have the function of rapid heat treatment, cannot restore the hardness and strength of the rail, and cannot solve the complete repair of the rail function

Embodiment Construction

[0025] The technical scheme of the present invention will be further explained below in conjunction with the drawings.

[0026] Such as figure 1 As shown, a rapid online detection and recovery device for rails includes a locomotive 18 and its control system set on a rail 19, the locomotive 18 is provided with driver doors and windows 17, and a data acquisition system and a main control system are installed on the locomotive 18 16. The rapid heat treatment system and the rail grinding system, the main control system 16 is respectively connected with the locomotive control system, data acquisition system, rapid heat treatment system and rail grinding system;

[0027] The data acquisition system is used to detect the smoothness and hardness data of the rail 19, and transmit the collected data to the main control system 16. The data acquisition system includes the main horizontal contour photoelectric sensor 1 installed under the front body of the locomotive 18. Sensor 2 and hardness t...

Abstract

The invention discloses a rapid on-line detection and recovery device for rails, which includes a data acquisition system, a main control system, a rapid heat treatment system and a rail grinding system. The grinding system is connected; the data acquisition system includes a main horizontal profile photoelectric sensor, an edge profile photoelectric sensor, a hardness tester A, a secondary horizontal profile photoelectric sensor and a hardness tester B; the rail grinding system includes a pre-grinding grinder, a grinding grinder, and a rough polishing machine and fine polishing machine; the rapid heat treatment system includes a flat-type quenching induction coil, a water spray gun, a flat-type tempering induction coil and a water tank. The present invention recovers its hardness, strength, smoothness and smoothness by quickly grinding and polishing the surface deformation of the track; adopts rapid induction heating quenching + tempering to overcome the decrease in surface hardness caused by cyclic loads and repeated elastic-plastic deformation of the track tread Softening effect, high maintenance efficiency.

Description

Technical field [0001] The invention belongs to a railway rail wear repairing technology, and particularly relates to a rapid on-line detection and recovery device for rails. Background technique [0002] The rail is the exclusive road for rail vehicles. The upper surface of the rail is the key working part, called "tread". When the wheels pass by, they are subjected to local pressure, shearing force and sliding-rolling wear, and they are subjected to complex fatigue loads. In particular, the so-called "corrugation" causes local wear and small plastic deformation on the surface. Moreover, it has been exposed to the atmospheric environment for years and months, and withstands atmospheric corrosion and corrosion by dew, fog, salt spray and rain. At the same time, in many special road sections such as stations and freight yards, it is also exposed to slag, sand, coal and other more harsh corrosive substances. Corrosion, harsh service environment, local damage to the tread surface a...
