The invention has the beneficial effects as follows: the present invention is owing to adopted the load sensing hydraulic control technology; Thereby have the top and drive the rotation speed governing; Keep moment of torsion during stall, the drilling rod moment of torsion discharge and with the function of power tongs interlocking, the practicing of the ram technology of driving of having realized deep-well.
Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.
Accompanying drawing is a structural representation of the present invention.
The specific embodiment:
Shown in accompanying drawing, the 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 links to each other with the import of hydraulic control proportional reversing valve 5, and two outlets of hydraulic control proportional reversing valve 5 link to each other with two actuator ports of motor 10 with one way valve V14 through one way valve II6 respectively; The outlet of control pump 1 links to each other 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 I3 simultaneously; The outlet of shuttle valve I3 links to each other with the control mouth of pilot operated directional control valve II15, and the import of pilot operated directional control valve II15 links to each other with the control mouth of variable pump 18, and outlet links to each other with the outlet of shuttle valve II12; Two imports of shuttle valve II12 link to each other with two actuator ports of motor 10; The outlet of control pump 1 links to each other with the import of proportional pressure-reducing valve 13, and the outlet of proportional pressure-reducing valve 13 links to each other with the control mouth of motor 10; The import of handle 17 links to each other with the outlet of control pump 1, and outlet links to each other with the control mouth of hydraulic control proportional throttle valve 8; The import of hydraulic control proportional throttle valve 8 links to each other with two actuator ports of motor 10 with one way valve IV11 through one way valve III9 respectively, the outlet connected tank; The outlet of handle 17 links to each other with the control mouth of hydraulic control one-way valve 16; The outlet of hydraulic control one-way valve 16 links to each other with the outlet of variable pump 18 and the import of hydraulic control proportional reversing valve 5, and the import of hydraulic control one-way valve 16 links to each other with the import of one way valve V14 and the outlet of hydraulic control proportional reversing valve 5; The import of one way valve I4 links to each other with the import of one way valve V14 with one way valve II6 respectively, the outlet connected tank; The import of pilot operated directional control valve I7 links to each other with two actuator ports of motor 10 respectively with outlet, and the control port of pilot operated directional control valve I7 links to each other with the control port of power tongs.
The top is driven rotating tee and is crossed motor 10 and drive, and speed is divided into three gears, and these three gears are to realize through the control port pressure that changes motor 10, i.e. the corresponding different discharge capacity of Different control pressure, and under identical flow, the discharge capacity friction speed is just different.When normally rotating speed governing, through the pressure of resize ratio reducing valve 13, can change the top and drive the gear of rotary speed, in each shelves,, can drive the top and carry out stepless speed regulation through regulating the aperture of joystick 2.When stall was driven on the top, motor built the pressure, and the maintenance moment of torsion is driven on the top.
When discharging the drilling rod moment of torsion, through the aperture of regulating handle 17, can control the opening of hydraulic control proportional throttle valve 8, thereby the high pressure chest pressure that motor is driven on the top is slowly discharged, handle 17 can be controlled the speed of release, has realized that the moment of torsion of drilling rod discharges.
When power tongs and torque tong during in last shackle; Can provide one tunnel control signal oil control pilot operated directional control valve I7 simultaneously; Pilot operated directional control valve I7 is communicated with two chambeies of motor 10, and motor 10 is in the servo-actuated state, along with the drilling rod rotation; Shackle operation in the completion has realized Power Tong and has pushed up the safety interlock between driving.
It is understandable that; More than about specific descriptions of the present invention; Only be used to the present invention is described and be not to be subject to the described technical scheme of the embodiment of the invention; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the present invention, to reach identical technique effect; As long as satisfy the use needs, all within protection scope of the present invention.
