The invention discloses a tension balancing device for traction steel wire ropes of a mining elevator. The tension balancing device comprises an electric hydraulic pump, a communicating vessel, a plurality of steel wire ropes, a plurality of hydraulic cylinders, an adjusting nut, a spring, a spring seat, a rope head screw rod, a rope head wedge sleeve, a weighing device, a hydraulic sensor, an electric stop valve and a filtering membrane. The pressure sensors are installed on the hydraulic cylinders, the pressure of the hydraulic cylinders is monitored in real time, signals are transmitted to the programmable logic controller, the signals are processed through the programmable logic controller and then fed back to the electric hydraulic pump and the electric stop valve, the pressure of the hydraulic cylinders is adjusted in real time, and then the tension of the traction steel wire rope is kept consistent; a set of springs is arranged on each hydraulic cylinder and used for adjusting jumping of the steel wire ropes in real time and assisting in adjusting tension of the steel wire ropes; and a set of filtering device is additionally arranged in an oil path, so that the influence of impurities on a hydraulic system can be effectively reduced.
本发明公开了一种矿用电梯曳引钢丝绳的张力平衡装置,包括电动液压泵、联通器、多条钢丝绳、多个液压缸、调节螺母、弹簧、弹簧座、绳头螺杆、绳头楔套、称重装置、液压传感器、电动截止阀和过滤膜;本发明通过在液压缸上安装压力传感器,实时监测各个液压缸的压力,并将信号传递至可编程控制器,通过可编程控制器处理后反馈到电动液压泵及电动截止阀,实时调整各个液压缸的压力,进而使曳引钢丝绳张力保持一致;还在每个液压缸上设置了一套弹簧,用来实时调整钢丝绳跳动及辅助调整各钢丝绳张力;还通过在油路中加入一套过滤装置,能有有效降低杂质对液压系统的影响。
