A gear pump is fixed to one side of the interior of a main machine part, a hydraulic oil tank is arranged at the bottom of the gear pump, a hydraulic control box is arranged on one side of the hydraulic oil tank, and an energy accumulator is arranged on one side of the hydraulic control box; a first electromagnetic directional valve, a second electromagnetic directional valve and a stacked pressure reducing valve are arranged in the hydraulic control box, the hydraulic control one-way valve is communicated with the input end of the energy accumulator through a first connecting pipe, a pressure sensor is arranged in a pipeline between the hydraulic control one-way valve and the energy accumulator, and one side of an output connector of the energy accumulator is fixedly communicated with a second connecting pipe. According to the device, an energy accumulator is added in an original clamping cylinder hydraulic system to store energy, so that the stability of clamping force is guaranteed, long-time high-pressure operation of a driving wheel and reduction of the service life of the driving wheel due to serious abrasion are prevented, and when a locomotive climbs in a heavy-load mode, a climbing mode is switched to increase the pressure of the clamping cylinder, so that traction force is increased, and the locomotive is prevented from sliding; and the locomotive can run safely.
本发明公开了一种防爆蓄电池单轨吊防溜车装置,主机部的内部一侧固定有齿轮泵,齿轮泵的底部设置有液压油箱,液压油箱的一侧设置有液压控制箱,液压控制箱的一侧设置有蓄能器,液压控制箱的内部设置有第一电磁换向阀、第二电磁换向阀和叠加式减压阀,液控单向阀通过第一连管连通于的蓄能器的输入端,液控单向阀与蓄能器之间的管路内设置有压力传感器,蓄能器的输出接口一侧固定连通有第二连管,装置在原有的夹紧缸液压系统中,添加一个蓄能器储备能量保证夹紧力的稳定性,防止驱动轮长时间高压力运行,驱动轮磨损严重寿命降低,并在机车重载爬坡时,切换为爬坡模式增大夹紧缸压力从而增大牵引力,防止机车溜车,使机车安全运行。
