Technical field
The invention belongs to oil and natural gas drilling equipment technical field, especially a kind of diameter of axle Integral type slips.
Background technique
In oil and natural gas drilling operation course, need toward tubing strings such as underground conveying drilling rod, casings.And the past ground of tubing string
In lower transmission process, slips is needed to be fixed.
The slips fixed currently used for drilling rod is divided into manual slip and automatic power slips.The range of manual slip clamping caliber
It is small, take manpower, influences working efficiency, and security risk is larger.Automatic power slips are axial type slips mostly, with oilfield exploitation
Depth is continuously increased, and oil well is drilled deeper, needs the slips of heavy caliber and high reliability, and axial automatic power slips at present
It cannot achieve radial adjustment, so that cannot achieve adjusting for bigbore tubing string；And currently used axial type slips
Clamping range it is smaller, to increase clamping range, slips body must be promoted up again, will make slips ruler over the entire structure
It is very little higher, reduce safety and production efficiency.
Summary of the invention
Technical problem solved by the invention is to provide a kind of diameter of axle Integral type slips, and solving existing slips cannot achieve
Radial adjustment, aiming at the problem that bigbore tubing string cannot achieve adjusting.
The technical solution for realizing the aim of the invention is as follows:
A kind of diameter of axle Integral type slips, including slips body, slip spider, axial elevating mechanism, be connected to adjust with slip spider and block
The radial compaction mechanism of watt seat along tubing string radial position；
The equalizer bar is mounted on the both ends of external tubing string, and the equalizer bar lower end at both ends is mounted on telescoping cylinder；It is described to stretch
Contracting cylinder right angle setting, the telescopic end and equalizer bar of telescoping cylinder are affixed, and telescoping cylinder lower end and external device (ED) are affixed, for driving balance
Axial elevating movement of the beam along tubing string；The slips body is two, is located at the lower end of drilling rod two sides equalizer bar, and pass through company
Linkage is hinged with equalizer bar；Equalizer bar drives the elevating movement of slips body under the telescoping cylinder driving of two sides；
The slips body contacts installation with slip spider, and slips body and slip spider contact surface are set as bevel structure, inclined-plane with
Drilling rod lower end is at an acute angle.
Compared with prior art, the present invention its remarkable advantage:
(1) diameter of axle Integral type slips of the invention, slips body slide on slip spider, are capable of forming the circle of diameter change
Cavity can be clamped smoothly and loosen the tubing strings such as drilling rod, casing, and have self-lock ability after clamping.
(2) by the rotation screw rod that is equipped with, slip spider can be made to slide on pedestal, do not increase total height this
Under the premise of one, there can be very big clamping range.
(3) diameter of axle Integral type kava structure of the invention is simple, easy to operate.
Present invention is further described in detail with reference to the accompanying drawing.
Detailed description of the invention
Fig. 1 is the overall structure diagram of diameter of axle Integral type slips of the present invention.
Fig. 2 is the structural schematic diagram that slip insert is equipped in slips body.
Specific embodiment
In order to illustrate technical solution of the present invention and technical purpose, with reference to the accompanying drawing and specific embodiment is the present invention
It is further to introduce.
A kind of diameter of axle Integral type slips of the invention, including slips body 8, slip spider 7, axial elevating mechanism, radial compaction
Mechanism；The axial direction elevating mechanism includes equalizer bar 2, hydraulic cylinder 3, link mechanism；
The equalizer bar 2 is mounted on the both ends of external tubing string, and 2 lower end of equalizer bar at both ends is mounted on telescoping cylinder 3；It is described
3 right angle setting of telescoping cylinder, the telescopic end and equalizer bar 2 of telescoping cylinder 3 are affixed, and 3 lower end of telescoping cylinder and external device (ED) are affixed, for driving
Axial elevating movement of the dynamic balancing beam 2 along tubing string；The slips body 8 is two, is located under drilling rod two sides equalizer bar 2
End, and it is hinged by link mechanism and equalizer bar 2；Equalizer bar 2 drives the lifting fortune of slips body 8 in the case where the telescoping cylinder 3 of two sides drives
It is dynamic.
The slips body 8 contacts installation with slip spider 7, and slips body 8 and 7 contact surface of slip spider are set as bevel structure, tiltedly
Face and drilling rod lower end are at an acute angle, and when so that slips body 8 moving upwards, slips body 8 is separated with drilling rod, when slips body 8 moves downward,
Slips body 8 and drilling rod compress.
In some implementation embodiments, slip spider 7 can be to be fixed, and slips body 8 is limited to the clamping range of drilling rod.This
In embodiment, the movement of slip spider 7 can be realized by radial compaction mechanism.
The radial compaction mechanism includes swivel nut 4, screw rod 5, fixing seat 6；Through-hole is equipped among the fixing seat, through-hole
It is axially perpendicular to the axial direction of tubing string, swivel nut 4 is installed in through-hole；The screw rod 5 is mounted in swivel nut 4,5 one end of screw rod and slips
7 active links of seat, end can be rotated around slip spider 7；6 bottom of fixing seat is equipped with guide rail, and slip spider 7 is mounted on fixing seat 6
Guide rail on, under the driving of screw rod 5, slip spider 7 can be moved in the radial alignment on guide rail, be realized to the compression of slips body 8
Or it unclamps.
Further, the telescoping cylinder 3 can be electric cylinder, cylinder or hydraulic cylinder.
In conjunction with Fig. 2, further, the slips body 8 and drilling rod contact surface be it is arc-shaped, circular arc shaped inside is equipped with installation
Slot is equipped with slip insert 1 in mounting groove, multiple rows of slip insert 1 is equipped in the axial direction along tubing string, and be equipped with soket head cap screw 9
Multiple rows of slip insert 1 is fixed, soket head cap screw 9 is screwed into slips body 8, compresses the slip insert 1 of one end, is realized to multiple rows of card
The limit of watt tooth 1 is fixed；The number of rows of the slip insert 1 is at least 3 rows, and slip insert and clamping can be increased by increasing slip insert number
The contact area of tubing string, and then increase the chucking power of slips body 8 and tubing string.
When slips working condition is to loosen, axial elevating mechanism work, the telescopic end uplink of telescoping cylinder 3, band dynamic balancing
Beam 2 and the slips body 8 connected by equalizer bar 2 move upwards, so that each slips body 8 is formed by the increasing of circular clamp cavity space
Add, drilling rod can be passed through from holding chamber.When slips working condition is to clamp, the telescopic end downlink of telescoping cylinder 3, band dynamic balancing
Beam 2 and the slips body 8 connected by equalizer bar 2 move downward, so that each slips body 8 is formed by the change of circular clamp cavity space
It is small, until as tubing string diameter with clamping drilling rod.
When the string size of clamping has large change to need to adjust clamping range, radial adjustment mechanism work rotates spiral shell
Rotary motion is changed into linear motion by bar 5, screw rod 5, drives the moving in the radial direction in drilling rod of slip spider 7, can be effective
Adjustment clamping range after having adjusted, the position adjusted can be kept to fix and since screw rod 5 has self-locking
It is constant, it is not only simple but also reliable.
Although the present invention has been disclosed as a preferred embodiment, however, it is not to limit the invention.Skill belonging to the present invention
Has usually intellectual in art field, without departing from the spirit and scope of the present invention, when can be used for a variety of modifications and variations.Cause
This, the scope of protection of the present invention is defined by those of the claims.
