Rescue robot's hydraulic system

The utility model provides a rescue robot's hydraulic system, each valves of entire system is parallelly connected, and the hydraulic pressure valves is for the sensitive electro -hydraulic proportional valve of load, by PLC controller and automatically controlled joystick control. Walking and landing leg valves are installed on caterpillar base plate and landing leg, and the jack -up lifts the arm valves and installs on the jack -up lifts the arm seat, and the hydraulic pressure oil circuit passes through swivel joint of four ways central authorities and the sensitive hydraulic pump connection of load respectively, and multichannel control scheme is connected with PLC controller and automatically controlled handle. The beneficial effects of the utility model are that: central swivel joint's oil circuit route quantity can be reduced by a wide margin, small, compact structure has been changed into. The problem of because of slewing bearing installation space is little, the unable assembly of many hydraulic pre
