Subway washing aerial work comprehensive vehicle

Abstract

The invention relates to an aerial operation comprehensive vehicle for metro washing. Manual cleaning is replaced by high pressure water tunnel washing, and a crank arm double-rotary-table aerial operation platform is adopted for replacing a scaffold or a vertical lifting platform to maintain metro tunnel walls and contact nets. The aerial operation comprehensive vehicle comprises a railway vehicle with power, an automatic control system, the crank arm double-rotary-table aerial operation platform, a double-power system and a high pressure water system, a vehicle body of the railway vehicle with power is of a double-fish-belly double-layer structure, the crank arm double-rotary-table aerial operation platform is installed on the upper layer, two water tanks of the high pressure water system are installed on the lower layer for supplying water, and a hydraulic cylinder is arranged between the vehicle body and a bogie to be capable of achieving rigid connection between the vehicle body and a steel rail; the crank arm double-rotary-table aerial operation platform is composed of a four-joint arm, a pull rod, double rotary tables and a hanging basket. The high pressure water system further comprises an inlet water filtering part, a booster pump, a high-pressure pump and a high-pressure pipe, and the high-pressure pipe is connected with a spraying rod.

Description

technical field [0001] The invention relates to the field of subway tunnel cleaning and high-altitude operation, in particular to a subway high-altitude operation integrated vehicle for high-pressure water flushing of rails, ballast beds, tunnel walls, and high-altitude inspection and maintenance of subway catenary and tunnel walls. Background technique [0002] At present, water leakage in the tunnel wall is common in domestic subways, which has adverse effects and even threats to the stability of the tunnel, facilities in the tunnel, traffic safety, ground buildings, and the water environment around the tunnel. In order to ensure the safety of subway operation, daily inspections are necessary to find leaks in time and deal with them immediately. However, due to the limited space of subway tunnels, numerous equipment, staggered catenary lines, and the height of the top of the tunnel from the rail surface, there is no bypass catenary at home and abroad. To inspect and repair...

[0002] At present, there is a common phenomenon of water leakage on the tunnel wall in the domestic subway, which has adverse effects on the stability of the tunnel, facilities in the tunnel, traffic safety, ground buildings and the water environment around the tunnel, and even threatens

In order to ensure the safety of subway operation, daily inspections must be carried out to detect leaks in time and deal with them immediately. However, due to the limited space of subway tunnels, numerous equipment, staggered catenary lines, and the height of the top of the tunnel from the rail surface, there is no bypass catenary line at home and abroad. To inspect and repair the aerial work vehicle on the top of the subway tunnel, the subway maintenance personnel can only use scaffolding or vertical lifts to maintain the tunnel wall which is only four meters above the rail surface, and there is nothing they can do for the tunnel top which is more than ten meters above the rail surface
