Novel railway ballast cleaning method

Abstract

A novel railway ballast cleaning method comprises the main following steps: A, after a ballast cleaning vehicle runs to an operation area, an operation trolley equipped with a blowing, sweeping and sucking combined work device is placed on a track; B, a dust suction fan is started, and rotating speed of the fan is enabled to reach operation rotating speed; C, a front roller motor and a rear rollermotor are started independently or simultaneously and drive rollers to sweep the surface of a ballast; D, the ballast cleaning vehicle sucks dirt on a passing way at an operation traveling speed; E,the sucked dirt is filtered by a primary dust removal, storage and transport device and stored in a dust collection box; F, dust-containing gas subjected to primary dust removal filtering passes through the dust suction fan, part of the gas is used for back blowing, and the other part of the gas is filtered by a secondary dust removal, storage and transport device and then discharged. The novel railway ballast cleaning method integrates mechanic, electric and hydraulic techniques and can perform cleaning, dust removal, transfer and storage on different dirt on the surface of the ballast.

Description

technical field [0001] The invention relates to a method for removing dirt and dust on the surface of a railway track bed and corresponding equipment, which are used for cleaning and collecting various dirt on the surface of the track bed, and belong to the technical field of railway maintenance machinery. Background technique [0002] At present, the dirt on the surface of the ballast bed mainly includes the following categories: a. small particle waste such as stones and sand particles produced by the construction before the ballastless track was opened; ; c. Sand collection on the surface of ballasted and ballastless track beds in desert areas; d. Coal particles dropped by coal trucks on coal transport lines, especially when passing through tunnels; e. Some wastes discarded by passengers. [0003] The above-mentioned dirt remains on the surface of the railway track bed, which not only affects the environment along the railway, but also affects the safe operation of the ra...

AI Technical Summary

Problems solved by technology

For example, on the ballastless passenger dedicated line, due to the high speed of the vehicles, the dirt such as gravel and sand accumulated on the surface of the ballast bed may damage the sensors or other electronic devices at the bottom of the vehicle after being picked up by the high-speed vehicles, resulting in vehicle failure or even damage Accidents; for the coal transportation line, the scattered coal powder rolled up when the train passes will affect the driver's sight, especially when the coal powder and coal lumps are deposited thickly, the rails will be buried, and long-term accumulation will also cause the ballast bed to harden. endanger the safety of the train

[0004] The dirt cleaning work on the surface of the railway track bed has been mainly done manually for many years. For example, after the rail grinding vehicle grinds the rails, about 30 people are needed to clean up the grinding dust generated each time; During the period of intensive maintenance and construction, all the long tunnels have cleaning construction teams working at the same time, which takes up a lot of maintenance time, and the dust pollution on site is serious, the working environment is harsh, and the labor intensity is high

[0005] At present, a variety of cleaning equipment has been developed for different passenger lines in China, but there are two problems: one is that these equipment mostly use the combination of sweeping and suction or blowing and suction, and the actual application effect is not ideal; the other is that the existing equipment Only for a single type of dirt, but not for a variety of different kinds of dirt, which reduces the versatility of equipment use, increases the difficulty of use and purchase costs for users, for example, the tunnel coal suction truck is dedicated to the collection of tunnel coal powder , The ballast bed desanding vehicle can only deal with the accumulated sand on the surface of the ballast bed
