Multifunctional concrete wet-spraying vehicle and control method thereof

Abstract

The invention discloses a multifunctional concrete wet-spraying vehicle and a control method thereof. The problems that an existing concrete wet-spraying vehicle is short in concrete spraying distance and incomprehensive in spraying are solved. The multifunctional concrete wet-spraying vehicle comprises a vehicle body which is provided with a feeding mechanism, a first vehicle head which is arranged at the front end of the vehicle body, a folding arm assembly, a hydraulic control mechanism and a three-gun type shower nozzle which is connected with the feeding mechanism. The folding arm assembly comprises a support, a first connecting arm, a second connecting arm and a third connecting arm, wherein the support is connected with the vehicle body through a turntable, and the first connecting arm, the second connecting arm and the third connecting arm are sequentially connected end to end. The tail end of the first connecting arm is connected with a support rotating shaft, and the first connecting arm, the second connecting arm and the third connecting arm are all connected with the hydraulic control mechanism and are controlled to be unfolded or folded together by the hydraulic control mechanism. The three-gun type shower nozzle is connected to the tail end of the third connecting arm through a rotating mechanism. The multifunctional concrete wet-spraying vehicle is stable in structure, diversified in function, capable of achieving long-distance, omnibearing and non-dead-angle automatic concrete spraying, high in construction quality and efficiency, convenient and fast to operate and free of potential risks.

Description

technical field [0001] The invention relates to a wet spraying vehicle, in particular to a multifunctional concrete wet spraying vehicle and a control method thereof. Background technique [0002] Concrete wet spraying is to mix concrete, cement and water evenly according to the design ratio, press it to the nozzle with a wet sprayer, and then add an accelerator to the nozzle and spray it out; compared with dry spraying and tidal spraying, wet spraying The concrete water-cement ratio is controlled accurately, the cement is fully hydrated, the quality is easy to control, and the amount of dust and rebound during the spraying process is small. At the same time, because the thickness of the primary spraying layer is greatly improved compared with the dry spraying, it is easy to meet the design spraying layer thickness requirements. Widely used jetting process. [0003] Concrete wet spraying truck is a kind of mechanical construction equipment widely used in tunnels, road slope...
