A large-height bridge wall cleaning vehicle

Abstract

The invention discloses a high-altitude bridge wall surface cleaning vehicle. The high-altitude bridge wall surface cleaning vehicle comprises a vehicle body assembly (1), a telescopic arm (2), a posture adjusting device (3), a scrubbing device assembly (4), a full-power broken-shaft transfer case (5), a water pump (6), a water tank (7) and a control device (8), wherein the posture adjusting device comprises a first-stage swinging mechanism (32), a second-stage swinging mechanism (37), a third-stage swinging mechanism (39) and a parallelogram four-connecting-rod variable-amplitude mechanism consisting of a main connecting rod seat (33), two connecting rods (34) and an auxiliary connecting rod seat (36); multi-degree-of-freedom adjustable scrubbing is realized by controlling each swinging mechanism and the four-connecting-rod variable-amplitude mechanism. The high-altitude bridge wall surface cleaning vehicle has high automatic degree, high cleaning efficiency and long single operation travel, can be used for scrubbing the bottom surfaces of flyovers and high level bridges or the top surfaces of tunnels, can be used for realizing one-time scrubbing of a plurality of scrubbing surfaces of bridge piers through fixed-point operation, is easy to operate, and is convenient in operation.

Description

technical field [0001] The invention relates to a wall surface cleaning vehicle, in particular to a large-height bridge wall surface cleaning vehicle, which 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 of overpasses, viaducts and tunnels. Over time, obvious stains are formed. The stains will not only affect the appearance, but also affect the lighting effect. Serious It even affects the driver's line of sight and thus affects driving safety. Usually, it is necessary to regularly clean and maintain the walls, sound insulation screens and guardrails to remove stains...

AI Technical Summary

Problems solved by technology

[0005] 1. The width of the car body assembly generally does not exceed the width of the roadway, and the length is generally not too long, resulting in the limited length of the folding arm and the limited scrubbing height of the scrubbing device assembly, which can only be used for low-height Wash the facade wall, sound insulation screen or guardrail. It is not possible to directly wash the facade wall with a height of more than 10 meters, the bottom plane of the overpass and viaduct, or the top surface of the tunnel. Usually, manual cleaning is still used, with the help of scaffolding. Or climbing work vehicles and other equipment for high-pressure water washing operations, not only 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. , the operation mode of high-pressure water flushing, residues are easy to be left on the operation surface after flushing, and in order to ensure long-term uninterrupted operation, the operation area needs to provide sufficient external clean water sources, and the operation 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 bridge piers, the direction of the car body needs to be adjusted in time according to the different washing surfaces, and fixed-point operations cannot be used to realize multiple washing surfaces of the bridge piers One-time cleaning, the operation is more complicated and inconvenient;

[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
