Abstract
The invention discloses a hydraulic control system for a mining full-hydraulic underground drill and belongs to the technical field of underground drill equipment. The hydraulic control system comprises a plunger pump, a multi-way reversing valve, a first pressure gauge, a second pressure gauge, a two-way hydraulic lock, a slope regulating oil cylinder, a rotary motor, a shuttle valve, a boosting oil way control block, a boosting oil cylinder, a holder, a one-way hydraulic lock, a chuck and a cooler. The hydraulic control system adopts a load sensitivity technique, the efficiency of the control system is improved, the problems that the control is lagged, the control precision is lower, and the system heating is severe are solved, and the energy-saving effect is good; the hydraulic control system adopts the load-sensitive manual proportional reversing valve, the control precision of the control system is improved, and the operation is simple and convenient; with the adoption of the boosting oil way control block, the drilling scope of a drill is extended, the problem that the drill skids when drilling at a large inclination angle is effectively solved, and the drilling safety is improved; and the holder and the chuck are combined and rotate reversely for automatically dismounting a drilling rod, the labor intensity for dismounting the drilling rod is reduced, and the working efficiency is improved.
Description
technical field [0001] The patent of the present invention relates to the technical field of tunnel drilling rig equipment, in particular to a hydraulic control system of a mine-used full hydraulic tunnel drilling rig. Background technique [0002] Mine full-hydraulic tunnel drilling rig is a drilling rig equipment specially used for drilling in underground tunnels. Exploration holes and other engineering holes. Mine full hydraulic tunnel drilling rig is mainly composed of pump station, operating platform, power head, stand, holder, column, drilling tools and so on. [0003] At present, fully hydraulic tunnel drilling rigs for mining mainly use quantitative or manual variable control systems, and the control components mainly use ordinary multi-way reversing valves, which have problems such as control lag, low control accuracy, serious system heat generation, and low efficiency. And when the drilling rig is drilling a large-angle pitch hole, the power head sometimes slips,...
