Railway tunnel sleeper outer ballast bed coal suction vehicle set and operation method thereof

Abstract

The invention discloses a novel railway tunnel ballast bed coal suction vehicle set and a corresponding operation method. The coal suction vehicle set comprises a side suction vehicle and a material vehicle, and a side suction vehicle frame (301) is installed on a third driving walking bogie (302) and a fourth driving walking bogie (311); the side suction vehicle frame (301) is n-shaped, at leastone set of the side suction working device (308) is arranged and located at the right-angle portion of an operation cab (307), the side suction working device (308) is connected with the side suctionvehicle frame (301) through a rotary supporting rotary table, the side suction working device (308) is fixedly connected with the rotary supporting rotary table, and a hydraulic motor drives a worm wheel to rotate via a worm, so that a mechanical arm swings out and in along the rotation axis. According to the railway tunnel sleeper outer ballast bed coal suction vehicle set, speed reduction designis conducted on the air ducts in the tops of a front draught fan chamber and a rear draught fan chamber of the side suction vehicle set, so that the ultrahigh air speed of a draught fan outlet is reduced to 2 m / s, and pulverized coal flying dust around the outlet is prevented.

Description

technical field [0001] The invention relates to a mobile railway track bed coal suction train set, in particular to a large-scale operating vehicle for absorbing dirt such as coal dust deposited on the surface of the track bed within a range of 2.6 meters in a railway tunnel, and belongs to the technical field of railway engineering equipment. Background technique [0002] Shenshuo, Shuohuang and Daqin coal transportation railway lines are mainly used for coal transportation. During the transportation process, due to the limitation of loading efficiency and technical means, the train cars full of coal are in an open state. When the train enters and exits the tunnel, due to the change of airflow , A small amount of surface coal powder filled in the carriage will be drawn out of the carriage by the airflow and scattered on the surface of the ballast bed. According to on-site feedback, the coal powder on the surface of the ballast bed is 10mm thick every day on average, and the...

AI Technical Summary

Problems solved by technology

There are several problems: (1) The efficiency of coal suction is low; (2) The dust collector is not designed for explosion-proof, which has serious safety hazards; (3) The dust removal effect is poor, and a large amount of coal powder is dispersed into the tunnel, and there is a risk of coal powder explosion; These problems have been around for a long time, and they are a major safety hazard that restricts the safe transportation of railways. It is urgent to develop special equipment that meets the actual work characteristics of the site and uses mechanical operations instead of manual operations.
