Abstract
The utility model discloses a kind of oil drill rocker and to link closely combined mechanism, comprises upper grip head and lower pliers head is two-layer.Upper grip head is made up of turnbuckle clamp and the pincers that link closely; Lower pliers head is made up of clamping clip.This mechanism not only reduces the volume of iron driller, makes iron driller smaller and more exquisite, and decreases turnbuckle clamp shake operationally, improves the reliability of iron driller, reduces the manufacturing cost of iron driller.
Description
Technical field
The invention belongs to petroleum machinery equipment manufacturing technology field, particularly a kind of combined mechanism that can carry out oil drill rocker and link closely.
Background technology
In recent years, domestic petroleum drilling equipment overall technology level is greatly improved, in the dismounting of drilling rod, use iron driller to achieve automation.The binding clip part of existing iron driller forms by three layers mostly: bottom is clamping clip, and centre is the pincers that link closely, and upper strata is turnbuckle clamp.The overall binding clips of three layers of composition take up room greatly, and due to torque ratio comparatively greatly, upper strata binding clip has shake when spinner.For reducing the volume of iron driller, turnbuckle clamp and the pincers that link closely are placed on one deck by mechanism, binding clip whole height is greatly reduced, also mitigates the shake of upper strata turnbuckle clamp simultaneously.
Summary of the invention
Mechanism designs for reducing well head iron driller volume.Mechanism is by upper grip head and lower pliers head is two-layer forms.Upper grip head comprises turnbuckle clamp and the pincers that link closely, and not only reduces the volume of iron driller, makes iron driller smaller and more exquisite, and decrease turnbuckle clamp shake operationally.Lower pliers head comprises clamping clip, by hydraulic mechanism by drill-rod clamping.Processing in the centre of upper strata two spinner wheel links closely with oil cylinder, allows together with the guide chute of spinner clamping head is worked into hydraulic cylinder shell, makes the overall frame as cupboard button device of hydraulic cylinder shell.When oil cylinder stretches out by drill-rod clamping, what the moment of torsion utilizing hydraulic pressure controllability to make to link closely reached drilling rod tightens requirement.
Accompanying drawing explanation
Fig. 1 is that oil drill rocker links closely combined mechanism front view;
Fig. 2 is that oil drill rocker links closely combined mechanism top view;
Wherein, 1-lower jaw, 2-upper jaw, 3-unclamps hydraulic oil inlet, 3_1-hydraulic oil channel, 4-clamping hydraulic oil-in, 4_1-hydraulic oil channel, 5-hydraulic cylinder piston, 6-hydraulic stem, 7-clamping head, and 8-spinner is taken turns, the public drilling rod of 9-, the female drilling rod of 10-.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described.
Female drilling rod (10) is fixed and clamps by two lower jaws (1) in left and right.Two upper jaws (2) in left and right also move to public drilling rod (9) and are clamped simultaneously.
Upper jaw (2) and lower jaw (1) are by after drill-rod clamping, and four, left and right sides spinner wheel (8) rotates to a direction simultaneously, and drive public drilling rod (9) to rotate, male drilling rod (9) and female drilling rod (10) carry out spinner under the motion of screw thread.Until whole screw thread is screwed.But do not reach the requirement moment of torsion of drilling rod.
After male drilling rod (9) and female drilling rod (10) screw thread screw, the clamping head (7) of the left and right sides is moved to drilling rod by hydraulic stem (6).
Hydraulic oil applies hydraulic coupling by clamping hydraulic oil-in (4), hydraulic oil channel (4_1) to hydraulic cylinder piston (5).Hydraulic coupling is delivered on clamping head (7) by hydraulic stem (6).And clamping head (7) is moved and clamps drilling rod.After reaching thrust, bit is made to produce relative rotary motion.Reach the tightening torque of drilling rod.
Unclamp clamping head (7), then hydraulic oil by unclamping hydraulic oil inlet (3), hydraulic oil channel (3_1) enters in hydraulic stem (6) chamber, promote hydraulic cylinder piston (5) and move round about.Clamping head (7) is unclamped.
Claims (3)
