Hydraulic walking driving system applied to miner-bolter and miner-bolter

The utility model discloses a hydraulic walking driving system applied to a bolter miner and the bolter miner, the hydraulic walking driving system can control a variable displacement motor to rotate forwards and backwards through a reversing control valve group, and can also adjust the speed and the highest working pressure of the variable displacement motor. Displacement switching of the variable displacement motor and braking switching of the brake can be controlled through the walking control valve set, switching of the walking driving system among multiple working modes can be achieved, and therefore the functions of braking, gear shifting and the like of the driving anchor machine can be achieved. Moreover, the open type hydraulic system adopting load sensitive control is simple and reliable, the maintenance difficulty under the severe working condition is greatly reduced, the power loss is small, the power consumption is low, and the cost of elements needing coal safety certification is low compared wi
