First of described nine multi-way valve are the revolution action connection that is connected with described impact rotating actuator, second of described nine multi-way valve are the leveling action connection that is connected with described leveling actuator, the 3rd of described nine multi-way valve are for subsequent use, the tetrad of described nine multi-way valve is the act arm action connection that is connected with described act arm actuator, the 5-linked of described nine multi-way valve is the pitching action connection that is connected with described pitching actuator, the 6th of described nine multi-way valve are that the extension action that is connected with described extension actuator joins, the 7th of described nine multi-way valve are that the compensating movement that is connected with described compensation actuator joins, the 8th of described nine multi-way valve are the swinging arm connection that is connected with described swing arm actuator, and the 9th of described nine multi-way valve be that the pivot angle that is connected with described pivot angle actuator moves and joins.
Described oil hydraulic pump is quantitative gear pump.
Described revolution action connection is commutated by the hydraulic control mode, described leveling action connection is commutated by automatically controlled mode, described for subsequent usely commutated by the hydraulic control mode, extended action connection, compensating movement connection, swinging arm connection and pivot angle action connection and commutated by the hydraulic control mode described act arm action connection, pitching action connection.
Adopt the hydraulic rock drill carriage of technique scheme with turning round and the luffing oil hydraulic circuit, by a kind of nine multi-way valve control, to turn round with luffing action (comprise leveling, lift arm, pitching, extension, compensation, swing arm, pivot angle) and be incorporated into together, provide pressure oil by a quantitative gear pump, realize above-mentioned everything control, revolution and luffing action share the method for salary distribution that an oil pump drives, by a kind of nine multi-way valve execution action is effectively made up, when realizing required action, optimize the layout of system, had more rationality.
The utility model is in many execution actions of hydraulic rock drill carriage, and revolution action and luffing action do not need the situation of moving simultaneously under the operating mode of normal operation; The revolution action request has stable flow, and luffing action is not so high to the stability of flow; The needed uninterrupted of revolution action is higher than, or approximates the required flow of two to three luffing actions; The flow that the metering pump relief valve can provide at pump is the shunting throttling during greater than the required flow of jib lubbing mechanism, because this part is cylinder action, and actuation time is very short, because can not cause than the macro-energy loss.Simplify hydraulic rock drill carriage hydraulic system, when having guaranteed to supply with revolution action regime flow pressure oil, pressure oil has been given the luffing action, provide a kind of more excellent solution for the oil pump of hydraulic rock drill carriage hydraulic system actuator distributes.
In sum, the utility model is a kind of designs simplification, when guaranteeing supply revolution action regime flow pressure oil, pressure oil is given the hydraulic rock drill carriage of luffing action with turning round and the luffing oil hydraulic circuit.
