Abstract
Provided is a drill pipe slip structure capable of retreating. The drill pipe slip structure comprises a slip base 1 and slips 2; slip grooves 3 are formed in the slip base 1 and used for containing the slips 2, the bevel faces of the slip grooves 3 are attached to those of the slips 2, each slip groove 3 is provided with a dovetailed guiding groove 31, one face of each slip 2 is provided with a dovetailed guiding plate 22, the other face of each slip 2 is provided with slip teeth 21, and the dovetailed guiding plates 22 are connected with the slips 2 through bolts. Compared with the prior art, by means of the technical scheme, the problem that slips of an existing drill pipe slip structure and a drill pipe are prone to be clamped together and difficult to separate is solved, and meanwhile the problem that slip teeth and the rotating drill pipe are collided to damage each other is avoided.
Description
Technical field
The invention belongs to geological prospecting apparatus field, it particularly relates to one kind can rollback drill pipe slip knot
Structure.
Background technology
Survey the drilling depth of industry drilling project from hundreds of rice to several kms, and the length one of drilling rod
As be 3-6 rice, complete a drilling project, several hundred or thousands root drilling rod pierced ground end and taking-up,
That is drill spindle will constantly fill with several hundred or thousands root drilling rod and tear open.As shown in figure 1, this is
Tighten and unclamp drilling rod and use to obtain more universal common drill pipe slip structure: include slip spider 1 and slips 2,
Slip groove 3 on slip spider 1 is used for accommodating slips 2, the inclined-plane phase of the inclined-plane of slip groove 3 and slips 2
Laminating, is mainly used in slips 2 is passed radial force, and the slips tooth 21 of slips 2 is used for " biting " drilling rod
4, to prevent drilling rod 4 from skidding.
The operation principle of common drill pipe slip structure is: slip spider 1 is up, and the inclined-plane of slip spider 1 heads on
The inclined-plane of slips 2, the space that slips 2 does not up move, can only draw close toward center, be formed to drilling rod
4 chucking power, drilling rod 4 is fixed, now as shown in Fig. 2 (a)；Slip spider 1 is descending, slips
Seat 1 inclined-plane and the inclined-plane of slips 2 separate by touching, and that is, slips 2 has been being radially in loosening state,
Now as shown in Fig. 2 (b).The problem of this common drill pipe slip structure is: the slips of slips 2
Tooth 21 is easy to be stuck with drilling rod 4, and needing with tup, drilling rod 4 to be carried out percussion makes it loosen,
Slips 2 could be allowed thoroughly to unclamp with drilling rod 4；In addition, be in loosening state in radial direction when slips 2 and
Again just when rotated, slips tooth 21 can collide drilling rod 4 with drilling rod 4, damage slips tooth 21 and bore
Bar 4.
Content of the invention
For solving the problems, such as in background technology, the invention provides one kind can rollback drill pipe slip structure.
The technical scheme is that one kind can rollback drill pipe slip structure, including slip spider 1 and slips
2；Slip groove 3 is had on slip spider 1, for accommodating slips 2, the inclined-plane of slip groove 3 is oblique with slips 2
Face fits, and slip groove 3 has dovetail gathering sill 31, and the one side of slips 2 has dovetail guide plate 22,
Slips tooth 21 is had on another side.
The further technical scheme of the present invention is: described dovetail guide plate 22 is with slips 2 with bolt connection.
Due to employing technique scheme, compared with prior art, the present invention solves existing drilling rod
The slips of slips structure is easily stuck with drilling rod it is difficult to detached problem；It also avoid slips simultaneously
Tooth with rotation in drilling rod touch together with mutual damage problem.
Brief description
Fig. 1 is the schematic diagram of existing common drill pipe slip structure；
Fig. 2 is the sectional view of existing common drill pipe slip structure；
Fig. 3 is the structural representation of the present invention；
Fig. 4 be the present invention sectional view.
Specific embodiment
Embodiment
As shown in Figure 3, Figure 4, one kind can rollback drill pipe slip structure, including slip spider 1 and slips 2；
Slip groove 3 is had on slip spider 1, for accommodating slips 2, the inclined-plane of the inclined-plane of slip groove 3 and slips 2
Fit, slip groove 3 has dovetail gathering sill 31, the one side of slips 2 has dovetail guide plate 22, separately
There is slips tooth 21, dovetail guide plate 22 and slips 2 are with bolt connection on simultaneously.
The operation principle of the present invention is: when needing to lock drilling rod 4, slip spider 1 is up, slip spider 1
Inclined-plane head on the inclined-plane of slips 2, the space that slips 2 does not up move, can only draw close toward center,
Form the chucking power to drilling rod 4, drilling rod 4 is fixed；When needing to separate with drilling rod 4, slip spider 1
Descending, slips 2 under the guide effect of dovetail gathering sill 31 and dovetail guide plate 22, radially away from brill
Bar 4 center, completes the separation process with drilling rod 4.
The present invention is not limited to above-mentioned preferred implementation, and anyone should learn the enlightenment in the present invention
Under the structure change made, every have with the present invention same or like as technical scheme, belong to
Protection scope of the present invention.
Claims (2)
1. one kind can rollback drill pipe slip structure it is characterised in that: slip spider and slips；On slip spider
There is slip groove, for accommodating slips, the inclined-plane of slip groove is fitted with the inclined-plane of slips, slip groove has
Dovetail gathering sill, the one side of slips has dovetail guide plate, and another side has slips tooth.
2. according to claim 1 can rollback drill pipe slip structure it is characterised in that: described swallow
Tail guide plate and slips are with bolt connection.
