Description

Technical Field

[0001] The utility model relates to the technical field of railway track rust removal, in particular to a rust removal device for railway tracks. Background Technique

[0002] Railway tracks are laid in the open air and are eroded by natural factors such as rain, sunlight, and sand and dust for a long time. The surface is prone to rust or scale. These rust layers and dirt not only affect the appearance of the tracks, but more importantly, when the rust layer is serious, it is easy to cause poor shunting of the track circuit, affect the transmission of railway signals, and thus endanger the safety of train operation. When rust removing, the surface of the tracks will be polished for rust removal.

[0003] In a rust removal device for railway tracks disclosed in the existing patent publication number CN220538280U, it includes two rust removal blocks. The inner cavities of the two rust removal blocks are fixedly sleeved with rust removal friction plates. There are two fixing bolts on the side parts of the two rust removal blocks. There are multiple pressing plates between the four fixing bolts and the two rust removal friction plates respectively. There are rotating support plates on the tops of the two rust removal blocks. There are multiple limiting plates on both sides of the two rotating support plates. There are rust prevention reagent boxes on the side parts of the two rust removal blocks. A second rotating wheel and a first rotating wheel are respectively arranged at the bottom sides of the two rust prevention reagent boxes and the two rust removal blocks; by placing the two rust removal blocks at both ends of the railway track and pulling the device, the railway track can be rust removed first, and then the rust prevention reagent can be sprayed and wiped, so as to reduce the rusting speed of the railway track.

[0004] When the above device is in use, the rust of the tracks can be removed. A friction plate is used for rust removal, and then the rust prevention reagent is sprayed and wiped. The rust prevention reagent usually contains a variety of chemical components. These components will release pungent odors when volatilizing, and the friction plate rubs for rust removal during movement, and the rust removal effect still needs to be improved. In view of the above problems, a rust removal device for railway tracks is proposed. Content of the Utility Model
