The invention has the beneficial effects as follows: the present invention is owing to have employed Load sensing hydraulic control technology, thus there is top and drive rotation speed governing, during stall keep moment of torsion, drilling rod moment of torsion release and with the function that power tongs interlocks, the hydraulic top achieving deep-well drives practicing of technology.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Accompanying drawing is structural representation of the present invention.
Detailed description of the invention:
As shown in drawings, control system is driven on a kind of hydraulically powered top, comprises control pump 1, joystick 2, motor 10 and variable pump 18; The outlet of variable pump 18 is connected with the import of hydraulic control proportional reversing valve 5, and two outlets of hydraulic control proportional reversing valve 5 are connected with two actuator ports of motor 10 with one way valve V 14 respectively by one way valve II 6; The outlet of control pump 1 is connected with the import of joystick 2, and two outlets of joystick 2 are received on two control mouths of hydraulic control proportional reversing valve 5, also receive in two imports of shuttle valve I 3 simultaneously; The outlet of shuttle valve I 3 is connected with the control mouth of pilot operated directional control valve II 15, and the import of pilot operated directional control valve II 15 is connected with the control mouth of variable pump 18, exports and is connected with the outlet of shuttle valve II 12; Two imports of shuttle valve II 12 are connected with two actuator ports of motor 10; The outlet of control pump 1 is connected with the import of proportional pressure-reducing valve 13, and the outlet of proportional pressure-reducing valve 13 is connected with the control mouth of motor 10; The import of handle 17 is connected with the outlet of control pump 1, exports and is connected with the control mouth of hydraulic control proportional throttle valve 8; The import of hydraulic control proportional throttle valve 8 is connected with two actuator ports of motor 10 with one way valve IV 11 respectively by one way valve III 9, outlet connected tank; The outlet of handle 17 is connected with the control mouth of hydraulic control one-way valve 16, the outlet of hydraulic control one-way valve 16 is connected with the import of hydraulic control proportional reversing valve 5 with the outlet of variable pump 18, and the import of hydraulic control one-way valve 16 is connected with the outlet of hydraulic control proportional reversing valve 5 with the import of one way valve V 14; The import of one way valve I 4 is connected with the import of one way valve II 6 with one way valve V 14 respectively, outlet connected tank; The import of pilot operated directional control valve I 7 is connected with two actuator ports of motor 10 respectively with outlet, and the control port of pilot operated directional control valve I 7 is connected with the control port of power tongs.
Top is driven and is rotated through motor 10 and drives, and speed is divided into three gears, and these three gears are that the control port pressure by changing motor 10 realizes, the discharge capacity that namely different controlled pressures is corresponding different, and under identical flow, discharge capacity friction speed is just different.When normal rotation speed governing, by the pressure of resize ratio reducing valve 13, the gear that rotary speed is driven on top can be changed, in each shelves, by the aperture of regulable control handle 2, can drive top and carry out stepless speed regulation.When stall is driven on top, motor builds the pressure, and maintenance moment of torsion is driven on top.
When discharging drilling rod moment of torsion, by the aperture of regulating handle 17, can control the opening of hydraulic control proportional throttle valve 8, thus the high pressure chest pressure slow releasing of motor is driven on top, handle 17 can the speed of Co ntrolled release, achieves the moment of torsion release of drilling rod.
When power tongs and torque tong are in upper shackle, a road control signal oil can be provided simultaneously and control pilot operated directional control valve I 7, two of motor 10 actuator ports are communicated with by pilot operated directional control valve I 7, motor 10 is in servo-actuated state, along with drilling rod rotates, complete shackle operation, achieve Power Tong and top drive between safety interlock.
