Novel coal suction vehicle set for railway tunnel ballast bed

Abstract

The invention provides a coal suction vehicle set for a railway tunnel ballast bed, which comprises a coal suction vehicle containing a coal suction vehicle frame, wherein the coal suction vehicle frame is connected with a middle working device; the middle working device is a ballast bed coal suction working device comprising a coal suction cover body mounted on a working trolley; a cover body structure connected with an adjusting mechanism as well as a working mechanism are arranged in the coal suction cover body; a sealing plate is also connected with the outer side of the coal suction cover body; the working mechanism comprises rolling brushes; the adjusting mechanism comprises a rolling brush mounting plate of which the upper side is connected with an off-running cylinder; the sealing plate is connected with an air suction pipe; the coal suction cover body is also connected with an air blowing pipe; the adjusting mechanism is connected to the cover body structure through a guide slot connected with an adjusting upper plate; the rolling brush mounting plate is arranged on the adjusting upper plate; the adjusting upper plate is connected with a connection adjusting plate through a spring; an adjusting frame lower plate is connected below the adjusting plate; and the cover body structure is also connected with support wheels capable of supporting the whole cover body structure on a sleeper when the cover body structure passes through the sleeper. The coal suction vehicle set avoids the blockage of a filter bag when coal ash in the airflow of a dust remover is serious.

Description

technical field [0001] The invention relates to a dirt cleaning device for a railway track bed, in particular to a novel railway tunnel track bed coal suction train unit for absorbing dirt such as coal powder on the surface of a tunnel track, and belongs to the technical field of engineering equipment. Background technique [0002] Because the carriage of the coal truck is open, when the coal train enters and exits the tunnel and passes the train in the tunnel, the air turbulence formed will roll out the coal powder and some coal blocks in the carriage, and scatter them on the surface of the track bed in the tunnel. The coal powder brought up during passing will seriously affect the train driver's sight, and when the coal powder and lumps are deposited thicker, the rails will be buried, endangering the safety of train operation. During centralized maintenance construction, tunnel decontamination is one of the main tasks of centralized maintenance construction, and currently ...

Problems solved by technology

[0005] At present, the sewage suction equipment that has been developed mainly relies on disk blowing, pipe vacuuming, water spraying or surrounding spraying to clean up the loose dust with a small specific gravity deposited on the surface of the railway track bed or the surface of the road. For the collection of thick coal powder inside the tunnel, there are the following shortcomings: first, the distance between the sewage suction port and the track surface is relatively large, and the sewage suction capacity is weak due to the influence of velocity attenuation after air diffusion; second, it is not suitable for two-way railways Tunnels are also not suitable for roads with uneven or wide road surfaces; third, they are not suitable for roads with long dust deposition time or compaction, and cannot clean solid particles with a large proportion; fourth, they cannot remove the sucked dirt Real-time output, less dirt storage
