Railway track rust removal device and method

Abstract

The invention discloses a railway track rust removal device and method. The device comprises a mobile platform; a shot blasting structure, an exhaust fan and a collecting box are borne on the mobile platform; a box body with a cavity is connected below the mobile platform; an opening is formed in the side surface of the cavity; the opening is used for being matched with a rail to form a closed operation cavity; the box body is provided with a first interface and a second interface which are communicated with the cavity; the first interface is communicated with the shot blasting structure; theshot blasting structure is used for spraying airflow carrying a spraying material onto the rail web through the first interface; the second interface is sequentially communicated with the exhaust fanand the collecting box. The shot blasting structure is used for spraying materials to a rail web, attached dust falls off due to impact vibration, a rail web base body is exposed, the sprayed materials, the dust and air are extracted by the exhaust fan in cooperation with the collecting box to be separated from an operation box, rust dust attached to a rail is removed, and the problem that the efficiency of an antirust agent is affected by residual dust is solved.

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
