The invention discloses a walking driving system applied to a crawler belt self-walking insulation bucket arm vehicle. The walking driving system comprises a first gear pump, a second gear pump, a second walking driving hydraulic motor and a first walking driving hydraulic motor. According to the walking driving system applied to the crawler belt self-walking insulation bucket arm vehicle, the electric proportional speed regulating valve is adopted, the linear proportional adjustable range is enlarged, the first walking driving hydraulic motor and the second walking driving hydraulic motor adopt two sets of same mutually independent pump valve control systems, so that the linear walking characteristic calibration of the crawler belt becomes simple, and the working efficiency is improved. The identity of factory debugging of equipment is improved, and the production cycle and cost are reduced. The median functions of the first electromagnetic directional valve and the fourth electromagnetic directional valve are M-type, when the system is in a standby working condition, pressure oil is directly unloaded to return to the oil tank, on-way resistance is small, the median functions of the third electromagnetic directional valve and the fifth electromagnetic directional valve for controlling the left-right walking driving hydraulic motor are H-type, return oil directly returns to the oil tank, and on-way resistance is reduced.
本发明公开了一种应用于履带自行走绝缘斗臂车的行走驱动系统,包括第一齿轮泵、第二齿轮泵、第二行走驱动液压马达和第一行走驱动液压马达。该应用于履带自行走绝缘斗臂车的行走驱动系统,采用电比例调速阀,加大了线性比例可调范围,而且第一行走驱动液压马达和第二行走驱动液压马达采用两套相同的相互独立的泵阀控制系统,使得履带直线行走特性标定变得简单,提高了设备出厂调试的同一性,降低生产周期和成本。第一电磁换向阀和第四电磁换向阀中位机能为M型,系统在待机工况下,压力油直接卸荷回油箱沿程阻力小,控制左右行走驱动液压马达的第三电磁换向阀和第五电磁换向阀中位机能为H型,回油直接回油箱,降低沿程阻力。
