Steel rail rust removal robot

Abstract

The invention discloses a steel rail rust removal robot which comprises a movably-arranged chassis, a horizontal rust removal mechanism provided with a horizontal rust removal part and a vertical rust removal mechanism provided with a vertical rust removal part. The horizontal derusting piece is matched and contacted with the upper surface of the steel rail; the vertical derusting piece extends into the rail groove and is matched and contacted with the side surface, exposed in air, of the steel rail; the horizontal rust removal mechanism and the vertical rust removal mechanism are both installed on the chassis. In the rust removal process, the steel rail rust removal robot can be suitable for rust removal of the embedded steel rail, automatic rust removal operation on the upper surface of the embedded steel rail and the side face, exposed in the air, of the embedded steel rail is achieved, the labor cost is reduced, and the rust removal efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of rail derusting equipment, more specifically, to a rail derusting robot. Background technique [0002] Rust removal methods generally include: shot peening or sandblasting, high pressure water derusting, chemical derusting, laser derusting, shot blasting, etc. Shot peening or sandblasting mainly uses particle jet erosion to achieve surface cleaning purpose, but the abrasives are generally not recyclable, affect other operations, and the environmental pollution is serious; high-pressure water derusting mainly uses high-pressure water and abrasives to destroy rust and surface attachments, without dust pollution, and does not damage the main structure, but equipped with When the high-pressure water pump is in operation, there are certain problems in the supply and recovery of water, and rust is easy to return after rust removal; chemical rust removal mainly uses acid to react with metal oxides to remove oxide...

Problems solved by technology

[0002] Rust removal methods generally include: shot peening or sandblasting, high pressure water derusting, chemical derusting, laser derusting, shot blasting, etc. Shot peening or sandblasting mainly uses particle jet erosion to achieve surface cleaning purpose, but the abrasives are generally not recyclable, affect other operations, and the environmental pollution is serious; high-pressure water derusting mainly uses high-pressure water and abrasives to destroy rust and surface attachments, without dust pollution, and does not damage the main structure, but equipped with When the high-pressure water pump is in operation, there are certain problems in the supply and recovery of water, and rust is easy to return after rust removal; chemical rust removal mainly uses acid to react with metal oxides to remove oxides on the metal surface, usually in pickling Finished in the groove, not suitable for buried rail derusting; no dust is generated during the laser derusting operation, and the derusting is thorough, and the derusting depth is controllable

However, there are many accessories, relatively high equipment costs, and relatively complicated operation methods. Since the buried rail is below the ground, the working space of the laser head is limited. Shot blasting uses a high-speed rotating impeller to throw abrasives to the steel surface. To achieve the purpose of rust removal, high efficiency, less pollution, but high cost of use, and the working space of buried rails is limited

[0003] Affected by the working space, equipment cost and derusting quality, most of the rail derusting robots in the prior art are not suitable for the derusting of buried track rails. Therefore, derusting is generally carried out manually. , the efficiency of derusting operation is low, and the dust pollution is relatively large
