Abstract

Disclosed is a sliding door structure comprising a grinding device with the above structure and a steel rail guiding vehicle. The structure comprises a first limiting part and a second limiting part, the first limiting part and the second limiting part extend in the operation direction and are arranged in parallel, the first limiting part is arranged on the top of the grinding device, and the second limiting part is arranged on the side portion of the grinding device; first and second baffles are arranged at the front and rear ends of the first and second limiting parts along the operation direction; the first sliding door and the second sliding door are installed between the first baffle and the second baffle in the operation front-back direction. The tops of the first and second sliding doors are connected to the first limiting part in a sliding or rolling manner, and the bottoms of the first and second sliding doors are connected to the second limiting part in a sliding or rolling manner. The first sliding door, the second sliding door, the first baffle and the second baffle form a closed structure for the side portion of the polishing device. The technical problems that due to the fact that an existing door structure is heavy and wide, disassembly, assembly and maintenance are inconvenient, or the opening and closing angle of a vehicle door is limited, and the upper space is limited can be solved.

Description

technical field [0001] The invention relates to the technical field of rail engineering machinery, in particular to a sliding door structure applied to a rail grinding vehicle, including a grinding device with the structure and a rail grinding vehicle. Background technique [0002] During the operation of the train, the rail is in a harsh working environment for a long time. Multiple factors such as dynamic action, natural environment and the quality of the rail itself often lead to the continuous deterioration of the rail surface condition and the deformation of the rail head, resulting in wave wear, fat edge, peeling, fish scales on the rail surface, etc. Defects seriously affect driving safety. Rail grinding can remove the unevenness of the rail surface and restore the rail head to the original design requirements, so as to effectively improve the wheel-rail relationship, slow down the development of rail surface defects, improve the smoothness of the rail surface, and pr...
