Derusting device and method for railway track

Abstract

The application discloses a railway track derusting device and method, including a mobile platform, on which a shot blasting structure, an exhaust fan and a collection box are carried, and a box body with a cavity is connected below the mobile platform. There is an opening on the side of the cavity, and the opening is used to cooperate with the track to form a closed working cavity. The box is provided with a first interface and a second interface communicating with the cavity. The first interface is connected to the shot blasting structure. The above-mentioned shot blasting mechanism is used to spray the air flow with the spray material on the rail waist through the first interface, and the second interface is connected to the exhaust fan and the collection box in turn, and the shot blasting structure is used to spray the spray material on the rail waist, and the impact vibration The attached dust falls off, exposing the rail waist substrate, and the sprayed material, dust and air are extracted out of the operation box by the exhaust fan and the collection box, so as to clean up the rust dust attached to the rail and solve the problem that the residual dust affects the performance of the antirust agent.

Description

technical field [0001] The present application relates to a railway track derusting device and method. Background technique [0002] After the rail is laid, it is prone to rust because it is often exposed to the sun and the rain alternately. The rail waist part of the bottom is prone to rust accumulation. If things go on like this, the strength of the rail waist part supporting the rail head will easily decrease in the long run, causing excessive deformation of the rail head, which will cause irregular vibration and noise of passing trains, making it difficult to ensure the safety of train operation . [0003] The inventors found that although the current railway maintenance personnel will apply anti-rust agents to the rail waist and rail bottom, which delays the corrosion of the rails to a certain extent, but after the rails are rusted, the accumulated rust will adhere to the surface of the rails, resulting in When the antirust agent is applied, it is difficult for the an...

[0002] After the rail is laid, it is prone to rust because it is often exposed to the sun and the rain alternately. The rail waist part of the bottom is prone to rust accumulation. If things go on like this, the strength of the rail waist part supporting the rail head will easily decrease in the long run, causing excessive deformation of the rail head, which will cause irregular vibration and noise of passing trains, making it difficult to ensure the safety of train operation

[0003] The inventors found that although the current railway maintenance personnel will apply anti-rust agents to the rail waist and rail bottom, which delays the corrosion of the rails to a certain extent, but after the rails are rusted, the accumulated rust will adhere to the surface of the rails, resulting in When the antirust agent is applied, it is difficult for the antirust agent to penetrate into the base part of the track through the rust, resulting in poor antirust effect, and it is difficult to effectively improve the antirust performance of the track; for this, the existing track derusting vehicle is driven by a locomotive, and the following There is a rust removal shovel matching the rail waist. When the rust removal vehicle moves as a whole, the rust removal shovel will shovel off the rust attached to the track under the action of thrust, so that the larger rust will be detached from the track, and then apply anti-rust However, although this method solves the problem that the antirust agent is difficult to penetrate the rust to reach the base part, a large amount of dust will appear during the process of shoveling the rust by the rust remover, which will affect the surrounding environment, and the dust will adhere to the rail After applying the anti-rust agent, the anti-rust agent will fall off with the dust, resulting in the problem of uneven application of the anti-rust agent; it is difficult for the anti-rust agent to exert its effectiveness, and the overall anti-rust performance of the track is still not good
