Fireproof and dustproof device of steel rail grinding trolley

Abstract

The invention discloses a fireproof and dustproof device of a steel rail grinding trolley. The fireproof and dustproof device comprises a middle baffle, cover plates, trolley doors, a dust collectingcurtain, end baffles and a fireproof curtain. The cover plates are arranged on the left side and the right side of the dust collecting curtain in the operation direction of the grinding trolley and installed on a frame of the grinding trolley. One side of the dust collecting curtain is connected to the bottom of the grinding trolley body, and the opposite side is connected with the cover plate. The trolley doors are arranged on the left side and the right side of the grinding trolley in the operation direction and hinged to the cover plates. The middle baffle is connected to the lower portionof the frame in a suspended mode, and the end baffles are arranged at the front end and the rear end of the grinding trolley in the operation direction and installed on the frame. The lower portions of the end baffles and the lower portions of the trolley doors are connected with fireproof curtains. The fireproof and dustproof device can solve the technical problems that an existing fireproof anddustproof device of the steel rail grinding trolley adopts a rigid connection structure, space utilization is inconvenient, maintenance is difficult, and potential safety hazards exist.

Description

technical field [0001] The invention relates to the technical field of rail engineering machinery, in particular to a fireproof and dustproof device for a 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 are likely to damage the infrast...
