Device and method for measuring lifting force of lifting steel wire rope of mining excavator
The invention discloses a device and a method for measuring the lifting force of a lifting steel wire rope of a mining excavator. The lifting force measuring device comprises a tilt angle sensor, a push stroke sensor, a rotary encoder and a data processing device; the tilt angle sensor is used for detecting the tilt angle value of the push-press bucket rod; the pushing and pressing stroke sensor is used for detecting the pushing and pressing stroke value of the pushing and pressing bucket rod; the rotary encoder is used for detecting the rotation angle of the hoisting steel wire rope reel; and the data processing device calculates the lifting force of the lifting steel wire rope at the current moment according to the received inclination angle value, the pushing stroke value and the rotation angle fed back at the same detection moment. According to the invention, the calibration of the lifting steel wire rope and the measurement of the lifting force are completed by using the inherent structural parameters of the tilt angle sensor, the push stroke sensor, the rotary encoder and the mining excavator, so that the problem that a real-time and long-time working sensor is mounted near a large-size moving bucket is avoided; and meanwhile, the impact damage of ore rock to the sensor during the shoveling operation of the bucket is avoided, and the reliability is relatively high.
本发明公开了一种矿用挖掘机提升钢丝绳提升力测量装置及其方法。提升力测量装置包括倾角传感器、推压行程传感器、旋转编码器及数据处理装置；倾角传感器用于检测推压斗杆的倾角数值；推压行程传感器用于检测推压斗杆的推压行程数值；旋转编码器用于检测提升钢丝绳卷筒的旋转角度；数据处理装置根据所接收到的同一检测时刻反馈的倾角数值、推压行程数值以及旋转角度，计算出提升钢丝绳在当前时刻的提升力。本发明利用倾角传感器、推压行程传感器、旋转编码器和矿用挖掘机自身固有的结构参数完成提升钢丝绳的校准和提升力测量，避免了在大尺寸运动的铲斗附近安装实时、长时工作传感器的难题，同时避免了在铲斗铲装作业时矿岩对传感器的冲击破坏，具有较高的可靠性。
