Problems solved by technology

The spraying manipulator is used to spray concrete in the tunnel, and the space inside the tunnel is generally narrow, the road conditions are poor, and the light is dark, which brings great inconvenience to the reverse driving of the spraying manipulator, and there are also great safety hazards that affect production. efficiency
2. Although the rotary table of the injection robot arm frame has achieved a secondary structure, its injection range is still limited, which affects the adaptability and efficiency of the injection robot arm during construction
Once the power provided by the hydraulic system of the spray manipulator fails during the construction process, not only the concrete spray work cannot be carried out, but even the removal of the entire vehicle from the construction tunnel will encounter obstacles

Abstract

The invention discloses a jet manipulator. The jet manipulator comprises bodywork, a traveling wheel, an arm support, a traveling operation system, an arm support hydraulic system and an arm support rotary table supporting and traveling structure; the traveling wheel and the arm support are arranged on the bodywork; the traveling operation system is connected with the traveling wheel; and the arm support hydraulic system controls the work of the arm support. The jet manipulator has the advantages of high suitability, reliable work, high efficiency and flexible use.

Description

technical field [0001] The invention belongs to concrete spraying equipment, in particular to a spraying manipulator capable of spraying high-viscosity concrete. Background technique [0002] Using spraying manipulators instead of manual spraying of high-viscosity concrete has been widely used in underground tunnel construction in Asia, Europe and the United States in recent years because of its relatively low cost, high safety factor, and wide application range. With the construction of high-speed railways in our country, more and more tunnels are being excavated, and the use of jet manipulators is becoming more and more extensive. [0003] At present, the injection manipulators at home and abroad have the following situations: 1. They all adopt one-way driving, and only use one cab to control the forward, backward and steering of the vehicle. The spraying manipulator is used to spray concrete in the tunnel, and the space inside the tunnel is generally narrow, the road con...
