Abstract
The utility model relates to a hydraulic control system of a vehicle-mounted drilling rig and belongs to a hydraulic control system. The hydraulic control system of the vehicle-mounted drilling rig comprises a motor, an oil tank and a double-linked gear pump. The double-linked gear pump consists of a high pressure pump and a low pressure pump. A multiple directional control valve connected to the high pressure pump is a triple multiple directional control valve and a multiple directional control valve connected to the low pressure pump is a sextuple multiple directional control valve. The hydraulic control system is capable of meeting the requirement of a water well drilling rig system due to the adoption of the double-linked gear pump and achieving control and coordination inside the hydraulic system due to the adoption of the multiple directional control valves and a matched relief valve. By the adoption of a hydraulic lock, a support oil cylinder is enabled to stay at any position and does not shift position under an external force. The hydraulic cylinder is utilized to replace manual operations so that not only labor power is decreased, but also accuracy and work efficiency of the control system are enhanced and coordination of operations among hydraulic control elements is strengthened.
