Problems solved by technology

At present, the use of large-scale rail grinding vehicles for derusting requires a transportation plan, and the on-site derusting and grinding also takes up the line to affect the driving transportation, and the cost is relatively high. The use time after derusting is short, and periodic grinding and derusting is required; When manual derusting work is carried out with a disc or angle grinder, not only the labor intensity is high, the efficiency is low, and the quality is difficult to guarantee, but also the manual grinding with the grinding wheel is very easy to cause damage to the rail, and the grinding effect with the steel brush of the angle grinder is not enough. to rust removal requirements

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0021] A vehicle-mounted track laser rust removal system, such as figure 1 As shown, it includes a power supply 5 for power supply, a laser host 1 for generating a laser beam, and a derusting head 2 for irradiating a linear laser beam on the track after focusing the laser beam. The laser host 1 and the derusting head 2 are connected to each other through the optical fiber 3, and the laser host 1 and the power supply 5 are arranged on the train; Connected galvo and field mirrors.

[0022] Derusting head 2 is provided with two altogether, is respectively used to be located at train bo...

Abstract

The invention relates to a vehicular rail laser rust removal system which comprises a laser host and a rust removal head, wherein the laser host is used for generating laser beams, the laser beams are focused to obtain linear laser beams, and the linear laser beams irradiate on a rail through the rust removal head. The laser host is connected with the rust removal head, the laser host is arranged on a train, and the rust removal head is arranged on the outer lower portion of the train. Compared with the prior art, laser technique replaces traditional grinding technique, contact abrasion is omitted, rail base materials cannot be broken, new danger sources and pollution sources are not introduced, the system is low in energy consumption, free from consumable and maintenance and stable in performance, and use cost is greatly reduced.

Description

technical field [0001] The invention relates to a rail rust removal technology, in particular to a vehicle-mounted rail laser rust removal system. Background technique [0002] Steel rails are naturally rusted by wind and rain erosion in the open air, and an oxide layer is formed on the rail surface, which may easily cause poor track circuit shunting and endanger driving safety. In addition, the dust generated in the freight yard or cargo loading and unloading process of the train is scattered on the rail surface or brought to the rail surface by the locomotive wheel set, and then rolled by the train wheels, the rail surface forms an insulating layer, which is the same as the rusty oxidation. The same layer, the impedance of the rail surface increases, which is easy to cause poor track circuit shunting, and also affects driving safety. Rusted or polluted rail surface is extremely harmful to driving, which is crucial to driving safety and is not allowed to happen. Therefore...
