Control system for concrete wet spraying trolley and wet spraying trolley
The invention relates to the technical field of engineering machinery, and discloses a control system for a concrete wet spraying trolley and the wet spraying trolley. The control system comprises a hydraulic flow meter which is arranged in the pumping hydraulic drive loop and used for detecting the displacement of concrete; the first valve is arranged in the additive hydraulic driving loop and used for adjusting the output flow of the additive; the second valve is arranged in the compressed air loop and is used for adjusting the displacement of the compressed air; the controller is configured to obtain a flow signal of the hydraulic flow meter; generating a first control signal according to the flow signal, and outputting the first control signal to the first valve to control the opening degree of the first valve so as to adjust the output flow of the additive; and a second control signal is generated according to the flow signal, and the second control signal is output to the second valve to control the opening degree of the second valve, so that the displacement of the compressed air is adjusted. The spraying effect can be improved, and the rebound rate of concrete is reduced.
本发明涉及工程机械技术领域，公开了一种用于混凝土湿喷台车的控制系统及湿喷台车。控制系统包括：液压流量计，设置于泵送液压驱动回路中，用于检测混凝土的排量；第一阀门，设置于添加剂液压驱动回路中，用于调节添加剂的输出流量；第二阀门，设置于压缩空气回路中，用于调节压缩空气的排气量；控制器，被配置成：获取液压流量计的流量信号；根据流量信号生成第一控制信号，并向第一阀门输出第一控制信号，以控制第一阀门的开度，从而调节添加剂的输出流量；根据流量信号生成第二控制信号，并向第二阀门输出第二控制信号，以控制第二阀门的开度，从而调节压缩空气的排气量。本发明可以提升喷射效果，降低混凝土的回弹率。
