The invention relates to a mining dump truck lifting system with a load capacity detection function and a using method thereof, the mining dump truck lifting system comprises a lifting pump connected with a hydraulic oil tank, the lifting pump is connected with a lifting oil cylinder through a lifting proportional valve, a rodless cavity of the lifting oil cylinder is provided with a pressure sensor, a lifting angle sensor is arranged on a carriage of a mining dump truck, and a slope sensor is arranged on a truck body. The system further comprises a controller, the input end of the controller is connected with the pressure sensor, the lifting angle sensor and the gradient sensor, and the output end of the controller is connected with the lifting pump and the lifting proportional valve. The controller controls the lifting proportional valve to drive the lifting pump to lift in a small range, pressure value calibration in the reference state, the no-load state and the full-load state is achieved, after calibration of the three states is completed, load capacity detection is conducted, the load capacity of the vehicle is calculated, and the system is few in part, easy to install and maintain, low in cost and high in reliability. Automatic diagnosis of the detection system can be realized, so that system errors are reduced, and faults are eliminated.

    一种具有载重量检测的矿用自卸车举升系统及其使用方法,包括连接液压油箱的举升泵,举升泵通过举升比例阀连接有举升油缸,举升油缸的无杆腔设有压力传感器,矿用自卸车的车厢上设有举升角度传感器,车体上设有坡度传感器,还包括控制器,控制器的输入端与压力传感器、举升角度传感器和坡度传感器连接在一起,输出端与举升泵和举升比例阀连接在一起。本发明通过控制器控制举升比例阀带动举升泵小幅度举升,实现在基准状态、空载状态和满载状态的压力值标定,在完成三个状态的标定后,进行载重量检测,实现车辆载重量的计算,该系统的零部件少,易于安装和维护,成本低,可以实现检测系统的自动诊断,以减少系统误差、排除故障。
