operating principle
1. intelligent brake:
41-brake, 1411-brake shaft, 1412-brake cylinder, 1413-brake(-holder) block, 142-electromagnetic valve
By controlling the brake cylinder 1412 of brake, thereby can make brake(-holder) block 1413 closure brake axle 1411(not rotate); Because brake shaft 1411 and chain sprocket 42 and feeding motor 41 are coaxially fixedly connected, when brake shaft 1411 is braked, chain sprocket and feeding motor are also subject to braking (can not rotate).
During operation transition: electromagnetic valve 142 the disconnected guide's hydraulic oil source P1 of TURP, brake cylinder 1412 returns to normal, and holds out against brake(-holder) block and makes brake(-holder) block closed, thereby make brake shaft 1411 brakings, and then make feeding motor 41 and chain sprocket 42 brakings by self spring force;
During operation: electromagnetic valve 142 dead electricity, guide's hydraulic oil source P1 makes brake cylinder 1412 spring force compressions, and 1413 separation of piston driving brake(-holder) block are opened, and brake shaft 1411, chain sprocket 42 and feeding motor 41 return to normal and can freely move;
When stopping: guide's hydraulic oil source P1 is zero, brake cylinder 1412 leans on the spring force of self to hold out against brake(-holder) block 1413 and makes brake shaft 1411 brakings, and then makes feeding motor 41 and chain sprocket 42 brakings.
2. the control of drilling rod cutting:
When switching regulator hydraulic buttery valve 58 be in during electricity condition, guide's hydraulic oil source P1 conducting, its output circuit promotes the gauge tap commutation of main control valve 53 and connects the main hydraulic oil source P0 that supplies with cutting motor, main hydraulic oil source promotes 51 rotations of cutting motor by main control valve, cutting motor drives 54 rotations of unit head axle by transmission assembly, realizes smear metal action; Otherwise when switching regulator hydraulic buttery valve 58 is in power failure state, guide's hydraulic oil source P1 cuts off, the main hydraulic oil source of the gauge tap commutation sever supply cutting motor of main control valve, the stall of cutting motor, realizes drilling rod rotation, is the control of drilling rod cutting.
3. the control of double speed, two moments of torsion:
In the situation that flow pressure is certain, speed and the discharge capacity of cutting motor rotary speed are inversely proportional to, and the little rotary speed of discharge capacity is fast, and the large speed of discharge capacity is slow; And the size of motor output torque is directly proportional to discharge capacity, the little output torque of discharge capacity is little, and the large output torque of discharge capacity is large; By variable electromagnetic valve, can control cutting motor displacement size, thereby realize the control of double speed, two moments of torsion:
When variable electromagnetic valve is under power failure state, variable oil cylinder makes to cut motor in large discharge capacity, that is: in the situation that flow pressure is certain, cutting motor is in low-grade state, speed is low, and moment of torsion is large, and the unit head rotation output speed of cutting motor driving is low, moment of torsion is large, i.e. unit head rotation output " low-speed big ";
When variable electromagnetic valve be under electricity condition variable oil cylinder make to cut motor in small displacement, in the situation that flow pressure is certain, cutting motor is in quick shelves state, speed is high, moment of torsion is little, the unit head rotation output speed of cutting motor driving is high, and moment of torsion is little, i.e. unit head rotation output " high speed low torque ".
When operation, when changing, rock stratum situation can adjust flexibly operating type to improve operating efficiency, and in rock stratum, hardness is softer, and pore-forming required torque is less, now can make unit head under " high speed low torque " state, realizes fast pore-creating and improves operating efficiency; In rock stratum, hardness is harder, and pore-forming required torque is larger, now can make unit head under " low-speed big " state, realizes and stablizes pore-forming raising operating efficiency, makes drilling efficiency reach best.
Above-described embodiment is preferably one of embodiment of the present invention.
