Railway tunnel full-section ballast bed coal suction vehicle set

Abstract

A novel railway full-section ballast bed coal suction vehicle set comprises a railway tunnel sleeper inner ballast bed coal suction vehicle set body and a railway tunnel sleeper outer ballast bed coalsuction vehicle set body, wherein the railway tunnel sleeper inner ballast bed coal suction vehicle set body comprises a main suction vehicle and a material vehicle, and the main suction vehicle andthe material vehicle are connected in sequence; the main suction vehicle comprises a main suction vehicle frame (201), and the main suction vehicle frame (201) is installed on a third driving walkingbogie (202) and a fourth driving walking bogie (207); a cabin (203), a main suction dust removal system (205) and a main suction fan chamber (208) are arranged on the main suction vehicle frame (201).By means of the railway tunnel full-section ballast bed coal suction vehicle set, full-section pulverized coal can be safely and efficiently cleaned; gravity dust removal, cyclone dust removal and cloth bag dust removal are adopted, and the dust emission concentration is smaller than or equal to 30 mg / m < 3 >.

Description

technical field [0001] The invention relates to a mobile coal-absorbing train set for a railway track bed, in particular to a large-scale operating vehicle for absorbing coal powder and other dirt deposited on the surface of a full-section track bed in a railway tunnel, and belongs to the technical field of railway engineering equipment. Background technique [0002] On Shenshuo, Shuohuang, and Daqin special coal lines, when coal trains enter and leave the tunnel, due to airflow changes, the surface coal powder inside the train car will be swept out of the car by the airflow and scattered on the surface of the ballast bed. The pulverized coal on the track bed keeps accumulating, thicker and thicker. In serious cases, the rails and fasteners will be buried. On the one hand, it will seriously affect the safe operation of the train; clean up. [0003] In the past, the dust-heavy areas in the tunnel were mainly cleaned manually, but this method was labor-intensive, the coal pow...

AI Technical Summary

Problems solved by technology

However, during the trial operation of the ballast bed sewage suction vehicle, it was found that, firstly, due to the influence of its working principle, the full section cannot be cleaned, or manual cleaning is required, which cannot reduce the dependence on personnel; secondly, the dust removal system does not adopt explosion-proof, explosion-proof and leak-proof The inside of the dust collector is full of flammable and explosive coal dust, and there is a hidden danger of dust explosion; the third is that the dust removal system uses gravity and cyclone dust collectors, and the dust removal efficiency is low, resulting in a large amount of fine coal dust being discharged from the fan outlet and dispersed in the half of the tunnel. Inside the closed environment, there is a serious risk of dust explosion

This problem has been around for a long time, and it is 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.
