The invention provides a dumper lifting alarm monitoring device and a lifting height control method. The dumper lifting alarm monitoring device comprises a control module, a flow collection module, a pneumatic control reversing valve and a lifting module. The pneumatic control reversing valve is communicated with an inlet of the flow acquisition module; the lifting module is communicated with an outlet of the flow acquisition module; the flow acquisition module monitors first oil quantity information flowing into the lifting cylinder from the pneumatic operated directional valve through the inlet and second oil quantity information flowing out of the lifting cylinder through the outlet in real time; the lifting cylinder is positioned in the lifting module; the control module is connected with the flow collecting module and used for obtaining the first oil mass information and the second oil mass information, determining the volume change of hydraulic oil in the lifting cylinder according to the first oil mass information and the second oil mass information, and judging the lifting height and the working state according to the volume change of the hydraulic oil. The invention further provides a dumper lifting height control method based on the device. The system can be suitable for various complex working conditions, is high in reliability, and has the function of accurately feeding back the lifting height in real time.
本发明提出了一种自卸车举升警报监测装置和举升高度控制方法,该装置包括控制模块、流量采集模块、气控换向阀和举升模块;气控换向阀与流量采集模块的入口连通;举升模块与流量采集模块的出口连通;流量采集模块实时监测从气控换向阀通过入口流入至举升缸的第一油量信息,以及通过出口流出举升缸的第二油量信息;举升缸位于举升模块中;控制模块与流量采集模块连接,用于获取第一油量信息和第二油量信息,并根据第一油量信息和第二油量信息确定举升缸内液压油体积变化,通过液压油容积变化判断举升高度及工作状态。基于该装置还提出了一种自卸车举升高度控制方法。本发明能适用多种复杂工况,可靠性强,具有实时精准反馈举升高度的功能。
