Abstract

The invention discloses a shotcreting vehicle. The shotcreting vehicle comprises a vehicle body, a spraying device, an arm rest, a power system, a control system, a concrete pumping system, an air compressor system and an external additive system. The vehicle body comprises a chassis and an auxiliary frame. The power system, the control system, the concrete pumping system, the air compressor system and the external additive system are all installed on the auxiliary frame. The power system comprises a power module and a hydraulic oil tank. The concrete pumping system, the air compressor system and the external additive system are all connected with the spraying device through pipelines, and the concrete mixed with additives is sprayed onto sprayed faces through the spraying device. According to the shotcreting vehicle, through the design that an L-shaped rotating arm is arranged at the end of a telescopic arm of a large arm and a small arm is connected to the rotating arm through a small arm rotating platform, the purpose of performing normal spraying operation in tunnels with smaller or irregular cross sections is achieved; an external power supply power device is provided with two motor pump units, and thus normal work of the shotcreting vehicle can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a concrete spraying vehicle. Background technique [0002] The working principle of the concrete spraying truck is to use compressed air to transport the ready-mixed concrete mixture to the nozzle of the sprayer through the pipeline, form a bundle after being mixed with accelerator, spray it on the surface to be sprayed at high speed, and quickly Condensation hardens, thereby forming the concrete support layer. Wet shotcrete technology is widely used in various construction fields because of its simple process and economical cost. [0003] Most of the jet machines used at present are small machines, and the supporting parts are scattered and arranged. This type of spraying machine cannot control the quality of the concrete well, the concrete is easy to rebound and collapse, the construction quality is poor, and the construction efficiency is low; the spraying head...
