An operation method of a large-height bridge wall cleaning vehicle

Abstract

The invention discloses a working method of a large-height bridge wall cleaning vehicle. The working method comprises the steps that a, the large-height bridge wall cleaning vehicle is parked at a proper position; b, supporting seats symmetrically abut against the front position and the rear position of a vibration damper plate type spring respectively; c, supporting wheels are supported on the ground in a contact mode; d, a lifting hydraulic cylinder is controlled to stretch so that a basic joint arm can be lifted to a proper height; e, telescopic joint arms stretch out of the basic joint arm by a proper distance; f, a leveling bracket is turned out and lifted to be horizontal; g; a washing device assembly rotates, and a rolling brush is in the state facing the washing face; h, the rolling brush rotates; i, the rolling brush is close to the washing face till the rolling brush is in contact with the washing face; j, a nozzle starts to spray washing water for washing; k, different washing modes are selected according to different washing faces. According to the working method of the large-height bridge wall cleaning vehicle, the bottom planes of high overpasses and viaducts or the top faces of tunnels can be washed, fixed point work can be achieved to wash multiple washing faces of a bridge pier at a time, operation is easy, and work is convenient.

Description

technical field [0001] The invention relates to an operation method of a wall surface cleaning vehicle, in particular to an operation method of a large-height bridge wall surface cleaning vehicle, and belongs to the technical field of bridge cleaning equipment. Background technique [0002] With the rapid development of my country's economy and the rapid increase of vehicle traffic flow, the number of overpasses, ring viaducts and mountain tunnels, river tunnels or lake tunnels in the city is increasing day by day. A large amount of dust rolled up by driving vehicles is mixed together and finally attached to the walls, sound insulation screens and guardrails. Over time, obvious stains are formed. The stains will not only affect the appearance, but also affect the lighting effect, and even seriously affect the driver's sight Affecting driving safety, it is usually necessary to regularly clean and maintain walls, sound insulation screens and guardrails to remove stains.

AI Technical Summary

Problems solved by technology

[0005] 1. Since the width of the car body assembly generally does not exceed the width of the roadway, and the length is generally not too long, the length of the folding arm is limited, and the washing height of the washing device assembly is limited, so it can only be used for lower heights. The facade walls, sound insulation screens or guardrails should be cleaned. The facade walls with a height of more than 10 meters, the bottom plane of overpasses and viaducts, or the top surface of tunnels cannot be directly cleaned. Manual cleaning is usually used. Scaffolding or climbing vehicles and other equipment for high-pressure water washing operations not only have low cleaning efficiency, poor cleaning effect, high labor intensity, high manpower, material resources and management costs, but also high-speed vehicles on the road also pose safety hazards to operators. At the same time, the operation method of high-pressure water washing is easy to leave residues on the work surface after washing, and in order to ensure long-term uninterrupted work, the work area needs to provide sufficient external clean water sources, and the work area is limited;

[0006] 2. Due to the limited washing height, it is not possible to wash the high parts of the bridge piers of overpasses or viaducts, and when washing the lower parts of the bridge piers, the direction of the car body needs to be adjusted in a timely manner according to the different washing surfaces, and fixed-point operations cannot be performed to achieve more piers The one-time washing of each washing surface is more complicated and inconvenient to operate;

[0007] 3. Due to the limitation of the length of the folding arm, when washing the facade wall, sound insulation screen or guardrail, the washing operation can only be carried out on the driveway closest to the facade wall, sound insulation screen or guardrail, and usually only one Work in one direction forward, not backward, that is, you can scrub while moving forward, but not backward while scrubbing. After a single scrubbing of the partial scrubbing surface, you need to turn around and come back to scrub again. The scrubbing operation mode is single, not only the operation The efficiency is low, and it takes a long time to occupy the road
