concrete spray truck

Abstract

The invention discloses a concrete shotcrete vehicle, which comprises a chassis system, a boom system, a pumping system, an air compressor system, an admixture system and a hydraulic system on board. The tank is connected to the hydraulic pump of the boarding hydraulic system; the boom system, pumping system, air compressor system and admixture system are connected to the boarding hydraulic system on the hydraulic oil road. The concrete shotcrete vehicle has strong power, high maneuverability, continuous operation capability, high reliability and stability during driving and operation, and can meet the requirements of rapid operation under various environmental conditions.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a concrete shotcrete vehicle which uses high-pressure air to spray ready-mixed mixture to a designated position at high speed. Background technique [0002] Concrete shotcrete vehicle is a kind of engineering machinery widely used in tunnels, subway engineering, rock engineering, underground engineering, highway engineering and engineering rescue. [0003] Please refer to figure 1 , figure 1 Schematic diagram of the working principle of the concrete shotcrete truck. [0004] Such as figure 1 As shown, the working principle of the concrete spraying truck is to use the concrete pump 1 to pass the ready-mixed mixture through the delivery pipe 2, mix it with compressed air and admixture at the nozzle 3, and then spray it to the sprayed surface at high speed to form a concrete support. Sheath. [0005] At present, most of the concrete spraying vehicle products are s...
