Movable trolley for cleaning subway tunnel

Abstract

The invention discloses a movable trolley for cleaning a subway tunnel. The movable trolley comprises a walking trolley body and a cleaning assembly. The cleaning assembly comprises a first cleaning support arranged on the upper surface of the bottom plate, the first cleaning support comprises a vertical Y-shaped support and rotating parts arranged at the tail ends of left and right branches of the top of the vertical Y-shaped support, each rotating part comprises limiting discs oppositely arranged front and back, and a through shaft is arranged between the limiting discs. The through shaft is sequentially and fixedly sleeved with a first ring body, a second ring body and a third ring body. The cleaning device further comprises a cleaning plate at the tail end and a scrubbing cylinder with scrubbing long bristles. Through the multi-section type design, the inner wall of a tunnel and the surfaces of various facilities are preliminarily washed through the high-pressure spray head at the front section, the inner wall and the surfaces of the various facilities are further washed through the rotating washing cylinder at the rear section, cleaning is thorough, and then ending washing is conducted through the high-pressure spray head at the rear section. Various common pollutants attached to the inner wall of the tunnel and the surfaces of various facilities can be effectively removed.

Description

technical field [0001] The invention relates to the field of tunnel construction machinery and equipment, in particular to a mobile trolley used for cleaning subway tunnels. Background technique [0002] During the construction process of the subway tunnel soil-built hole, as well as the equipment installation project behind the station, the exhaust gas and dust of various construction vehicles and construction equipment in the tunnel, and the cement attachments and oil stains generated during the construction are easy to deposit on the inner wall of the tunnel. Pollutants formed on the ground, especially on various facilities installed on different sections of the tunnel wall (including cable supports extending along the tunnel line and cables laid on the supports, pipes, catenary, electrical equipment, pedestrian walkways, etc.) , causing pollution to the tunnel environment, it is easy to cause adverse effects on the sensitivity and service life of electrical equipment in ...

AI Technical Summary

Problems solved by technology

[0005] Although the above-mentioned prior art can clean the inner wall of the tunnel, it is only suitable for the cleaning of the inner wall of the smoother road tunnel or main line railway tunnel, and obviously cannot be applied to the inner wall of the subway tunnel with a large number of supports, cables, pipelines and other facilities installed. It is impossible to clean the surface of various facilities installed on the tunnel wall. At the same time, the above-mentioned prior art is mainly aimed at partial cleaning of the tunnel section rather than simultaneous cleaning of the entire section, so the cleaning efficiency is low.
