Abstract

The invention relates to a wet concrete slurry-spray robot. The wet concrete slurry-spray robot is provided with a square chassis; the lower part of the chassis is provided with an engine, a chassis electric system cabinet and two pairs of symmetric wheels; the back side of the upper part of the chassis is provided with a supporting seat; the lower end of a telescopic manipulator is fixedly connected with the supporting seat; the manipulator is bent upwards and extends forwards; the upper part of the chassis is provided with an electric control cabinet and a hydraulic pump; the electric control cabinet is used for controlling the swinging and extension of the manipulator; the hydraulic pump is communicated with a main oil cylinder, a piston, a conveying cylinder, an S-shaped pipe and a discharging hole bent pipe in sequence; the side face of the conveying cylinder is communicated with the bottom of a stirring hopper; the discharging hole bent pipe is connected with a concrete spraying gun through a slurry spraying pipe; and the side face of the spraying gun is fixedly connected to the front end of the telescopic manipulator. The slurry-spray robot has the advantages of compact structure, running stability and safety, uniform slurry spraying and operating flexibility, and is widely applied on the occasions of mining enterprise tunnels, culverts, subways, water electricity and underground emergency work operation.

Description

technical field [0001] The invention relates to a concrete spraying device, in particular to a wet concrete spraying robot with high flexibility and safe operation. Background technique [0002] Shotcrete support is a support method widely used in the construction of mine roadways, various tunnels, underground buildings and high-rise building foundation pits in the world at present. It replaces the traditional wood and steel beam support, and most of them replace Build bricks. Although some tunnels are made of brickwork from the outside, they have been sprayed with a 30cm-40cm thick concrete layer before the brickwork, so the shotcrete layer plays a decisive role in supporting. [0003] At present, the known concrete injection equipment has a complex structure, high failure rate, and the ubiquitous defects of discontinuous delivery process and large vibration impact. Fatigue damage occurs under the environment, resulting in increased production costs and inconvenience to t...
