Description

Technical Field

[0001] The utility model relates to an on-line sandblasting device for a rail, belonging to the field of sandblasting devices. Background Art

[0002] In the prior art, residual stress is formed on the surface of the rail after laminar plasma strengthening treatment, so the surface of the rail needs to be sandblasted, and the sandblasting device is composed of a sandblasting box, a sandblasting gun, a lifting mechanism, a positioning mechanism and an abrasive circulation device. Therefore, the sandblasting box needs to be fixed at the position where the rail needs to be sandblasted through the positioning mechanism, and then the sandblasting gun is aligned with the position of the rail through the lifting structure, so that the surface of the rail can be sandblasted, thereby eliminating the local stress caused by the high-temperature plasma strengthening treatment of the rail. However, when sandblasting in the sandblasting box, the positioning structure and the position of the rail need to be repeatedly operated each time before sandblasting can be performed, which will delay the time required for sandblasting, thereby affecting the efficiency of sandblasting.
