Concrete spraying mechanical arm

Abstract

A concrete spraying mechanical arm only has the function of spraying concrete and does not have the function of concrete pumping. Crawler belt chassis are adopted for the mechanical arm and used for crawling. Leveling hydraulic air cylinders are arranged between a frame and the chassis, so that the mechanism arm performs construction on a ramp, wherein the gradient of the ramp is smaller than 30 degrees, and wet spraying performance is not affected. Hydraulic control is adopted for a multi-stage telescopic arm of a mechanical arm frame and can be freely operated in a narrow and long tunnel, a combination of manual speed adjustment and frequency conversion speed adjustment is adopted for the quantity of flows of additives, so that the control range of the quantity of flows of the additives is larger, and stepless adjustment is achieved. The mechanical arm can smoothly finish the concrete wet spraying operation in a narrow and small construction site and has the advantages of being small in size, light in weight, low in energy consumption and low in cost.

Description

technical field [0001] The invention relates to concrete wet spraying equipment, in particular to a self-propelled concrete wet spraying equipment with a remote control manipulator. Background technique [0002] At present, concrete wet spraying equipment is widely used in wet spraying construction. The concrete wet spraying machine with manipulator has superior performances such as high spraying quality, low rebound rate, short preparation time, high construction efficiency, safety and environmental protection. And gradually accepted by users. However, the existing wet spray manipulator integrates the two functions of concrete spraying and concrete pumping, which is not only expensive, but also bulky, and the construction conditions are limited, so it can only be used for large tunnel construction. In a small tunnel environment, the folding arm of the existing wet spray machine cannot be unfolded and retracted at all, and its wheeled chassis is also difficult to turn in t...
