Abstract

The invention discloses a guniting vehicle and an arm support structure of the guniting vehicle. The arm support structure of the guniting vehicle comprises a supporting seat and a working arm support as well as an oscillating arm, wherein the working arm support comprises a supporting seat connecting end and a working arm support tail end and is rotatably connected to the supporting seat in a vertical plane by the supporting seat connecting end; the oscillating arm is arranged at the tail end of the working arm support and is rotatably arranged in an oscillating plane being perpendicular to the vertical plane relative to the working arm support; and a jet device installing part for installing a jet device is arranged at one end, far away from the working arm support, of the oscillating arm. The arm support structure of the guniting vehicle can realize the accurate adjustment of the jet range of the jet device in a horizontal plane under the condition of relatively low energy consumption.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a boom structure of a spraying vehicle and the spraying vehicle. Background technique [0002] The spraying vehicle uses hydraulic pressure to transport the mixed concrete to the nozzle through the pipeline, connects compressed air and accelerator to the nozzle, and then sprays the concrete at high speed to the surface to be sprayed, and forms a concrete support layer after rapid solidification and hardening. Shotcrete vehicles are widely used in underground construction and emergency rescue projects such as railway road tunnels, water conservancy and hydropower, subways, mine roadways, etc. [0003] The shotcrete vehicle in the prior art includes a telescopic arm and a spraying device arranged at the end of the telescopic arm. During construction, the telescopic arm can perform amplitude-changing and telescopic movements in the vertical plane to change the spraying range o...
