The invention discloses a fireproof and dustproof device of a polishing trolley. The fireproof and dustproof device comprises a top cover plate, end baffles, a dust collecting channel, side baffles and a fireproof curtain. The dust collecting channel is arranged on the upper portion of the top cover plate, and dust generated in the grinding process enters the dust collecting device through the dust collecting channel. The side baffles are arranged on the lower portions of the two sides, perpendicular to the operation direction, of the top cover plate, and heat dissipation devices are arrangedon the side baffles. The end baffles are arranged on the lower portions of the two sides of the top cover plate in the operation direction, and detachable connecting structures are adopted between thetop cover plate and the side baffles and between the end baffles and the side baffles. The lower portions of the end baffles and the lower portions of the side baffles are connected with fireproof curtains. The technical problems that an existing fire-proof and dust-proof device of the polishing trolley adopts a rigid connection structure, cannot be rapidly disassembled and assembled, is inconvenient for space utilization and is inconvenient for maintenance operation can be solved.
Description
technical field [0001] The invention relates to the technical field of rail engineering machinery, in particular to a fire-proof and dust-proof device for a stepless air-adjusting type grinding trolley applied to a rail grinding vehicle. Background technique [0002] During the operation of the train, due to the long-term harsh working environment on the rails, it is prone to defects such as fat edges, wave wear, and fish scales on the rail surface, which seriously affects driving safety. The rail grinding machine can improve the smoothness of the rail by removing the irregularities of the rail surface, slow down the development of rail surface defects, and prolong the service life of the rail. The grinding trolley is the executive mechanism of the grinding operation and the key component of the rail grinding vehicle. During the operation of the rail grinding vehicle, on the one hand, the sparks and high-temperature iron filings generated during the rail grinding process ar...
