Tunnel side wall spraying machine

Abstract

The invention discloses a coating machine for side walls of a tunnel. The coating machine comprises a machine body, a coating main body, a mechanical arm and a spraying gun, wherein the coating main body, the mechanical arm and the spraying gun are arranged on the machine body. The coating main body comprises a storage tank for storing paint, a charging pump for pumping the paint, and a first drive motor for driving the charging pump. The mechanical arm comprises a fixed rod, a movable rod and a first hydraulic telescopic rod, the fixed rod is vertically arranged on the machine body, and the movable rod is connected with the fixed rod through a first hinge piece. The spraying gun comprises a feeding chamber, an equal-pressure distribution chamber and a plurality of sprayers for spraying out the paint. The feeding chamber is connected with a discharging pipeline through a conveying pipeline. The equal-pressure distribution chamber is in a flaring shape in the axial direction, and spray holes are evenly distributed in the equal-pressure distribution chamber. The sprayers are connected with the spray holes. The coating machine can coat the side walls of the tunnel with materials quickly and effectively, the labor intensity of workers is relieved, and the coating quality is improved.

Description

technical field [0001] The invention relates to a spraying machine, in particular to a tunnel side wall spraying machine. Background technique [0002] With the development of tunnel construction, especially urban tunnel construction, in areas with complex terrain, especially mountainous areas, tunnels are widely used due to their advantages of shortening road mileage, improving transportation efficiency, saving land and protecting the ecological environment. ; At present, my country is the country with the most tunnels and the longest total mileage in the world. Tunnel is a special driving environment. Once a traffic accident occurs, the loss is much greater than that of ordinary roads. Tunnel lighting conditions and fire performance are receiving more and more attention; because fireproof materials and reflective materials can well improve tunnel fire prevention capabilities and lighting quality , and its application cases in tunnel side walls are increasing. Tunnel side ...

AI Technical Summary

Problems solved by technology

Tunnel side wall materials (fireproof materials, reflective materials, etc.) have high requirements for spraying quality and a large spraying area. However, the current manual spraying method has the defects of high labor intensity, low spraying efficiency, and unstable spraying quality. Therefore, How to quickly and effectively spray materials on the tunnel side wall is an urgent and imperative task
