Description
Technical Field
The utility model relates to the technical field of subway tunnel cleaning, in particular to the technical field of energy-saving and environment-friendly subway tunnel ballast bed cleaning, and specifically relates to an adjustable flushing device for a subway bed.
Background
In the semi-closed space of the subway tunnel, the dust concentration of some subway stations exceeds the standard seriously, wherein the dust of metal micro-particles such as iron filings and the like generated by the friction between wheels and a track and the raised dust generated after passing through the subway vehicle can cause harm to human health and operation facilities and equipment and must be removed. Therefore, in order to improve the subway operation environment and improve the reliability and comfort of equipment, the tunnel must be regularly cleaned and maintained.
In addition, due to the piston effect of the running of the subway vehicle, part of dust in the tunnel is brought up, so that illumination and traffic signal lamps in the tunnel become dark, the image shooting effect of a camera is poor, electromechanical equipment is more prone to aging, and faults are more prone to occurring. Many of the failures of electrical equipment are caused by long-term accumulation of dust, such as local short circuit, electric leakage, and various failures caused by poor heat dissipation of heat-generating elements. The dust has great harm to the safe operation of the electrical equipment, the management must be strengthened, and effective technical means are adopted to reduce the dust harm to the minimum, thereby ensuring the safe operation of the equipment and obtaining good economic benefit and social benefit.
For the subway tunnel, the internal space is relatively closed, the space is narrow, the manual cleaning efficiency is low, and the operation is difficult. Therefore, the tunnel must be cleaned using specialized equipment.

The original cleaning method for the dust on the surface of an object mainly comprises two methods: brush-sweeping dust removal and adsorption dust removal. The brush sweeping type sweeper has serious dust emission in the sweeping process, cannot remove fine dust on the surface of an object, and is easy to cause secondary pollution; the adsorption type dust removal is poor in cleaning effect on some dust solidified on the surface of an object, secondary dust raising is still serious mostly when much dust exists, and cannot be eliminated fundamentally, particularly in northern areas with large wind sand, the phenomenon is more prominent, and the cleaning effect of the two cleaning methods on the subway tunnel is not ideal. Therefore, the tunnel cleaning dust removing equipment which can cope with the changeable ballast bed conditions in the tunnel and can overcome the technical problems encountered in the cleaning process is urgently needed in the cleaning work of the subway tunnel.
At present, the highway tunnel cleaning technology is researched more in China, but the subway tunnel cleaning technology is not paid enough attention, and the domestic research and the use are in the starting stage. Because various devices are installed in the subway tunnel, the maintenance of the cleanness in the tunnel is very important to the normal use of the devices, the maintenance and the safe operation of subway trains.
As a third water washing and cleaning mode of the subway tunnel, although the third water washing and cleaning mode is superior to a brushing and sweeping type dust removal mode and an adsorption type dust removal mode, the optimal washing effect can be achieved only by manually adjusting the reversing angle of the nozzle mounting frame according to the change of the driving direction of the railway ballast bed washing device, and the manual reversing is time-consuming and labor-consuming due to frequent corrosion or dust pollution of the reversing rotating mechanism, so that the labor intensity of operators is high, and sometimes even the mechanism is seized and cannot rotate the reversing.
