Abstract
A kind of Handheld type drilling rod thread protecting cap provision for disengagement, including shell body, it is relatively set with outer enclosure interior for the slips piece around drilling rod thread protecting cap, it is connected between slips piece by studs, shell body outboard end is provided with rotary handle, when the provision for disengagement of hand-held thread protecting cap uses, it is directed to the outer end of drilling rod thread protecting cap, start motor reversion button first, make two slips pieces under the drive of studs relative motion to farthest position, shell body is enclosed on drilling rod thread protecting cap, then stepper motor main story button is started, make two width slips piece move toward one anothers until holding the outer wall of drilling rod thread protecting cap tightly, then the handle of provision for disengagement is rotated, according to the direction for unloading screw thread, the lower drilling rod thread protecting cap of dismounting, the utility model has time saving and energy saving, the characteristics of improving drilling efficiency.
Description
Technical field
The dismounting of petroleum pipeline drilling rod thread protecting cap is the utility model is related to, more particularly to a kind of Handheld type drilling rod thread protecting cap dismounting
Device.
Background technology
At present, oil drilling scene, during using drill string, tubing string thread protecting cap needs driller by hand to dismantle thread protecting cap.
With the increase of well depth, the increase of drilling rod usage quantity, the workload of hand disassembly thread protecting cap increases therewith.With drilling automation
The development of process, the work of hand disassembly thread protecting cap will be also substituted, and the hand disassembly thread protecting cap course of work is simple, repeatability
Height, and dismantlement work also has certain danger.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a kind of Handheld type drilling rod thread protector
Cap provision for disengagement, the automatic dismantling instrument realizes that the dismantlement work of drilling rod thread protecting cap is not only simple to operation, time saving and energy saving, has
Beneficial to the overall drilling efficiency of raising, but also the safety of rig floor work can be effectively improved, reduce the labor intensity of driller.
In order to achieve the above object, the technical solution adopted in the utility model is：
A kind of Handheld type drilling rod thread protecting cap provision for disengagement, including shell body 3, are relatively set with inside shell body 3 and are used for
It is connected between the slips piece 1 of drilling rod thread protecting cap, described slips piece 1 by studs 2, the described outside of shell body 3
End set has rotary handle.
Spacing between described slips piece 1 is adjustable structure, is connected by the yielding coupling 5 with stepper motor 6, and
Controlled by the switch 7 on stepper motor 6.
Little gear 4 is installed on described slips piece 1.
The shell body 3 is cylindrical shape, and slips piece 1 sets within it wall, axle center of two slips pieces 1 on shell body 3
Symmetrically.
The beneficial effects of the utility model are：
The utility model avoids worker's hand from being contacted with the direct of drilling rod thread protecting cap, reduces the burst danger in unloading process
Danger, and by rotary handle, the dismantlement work of the drilling rod thread protecting cap made is more laborsaving, fast, efficiently.
The fixation little gear 4 installed on a vice card tile 1, which can contact original face, is changed into linear contact lay so that for
The holding of drilling rod thread protecting cap is more safe and efficient, reduces the problem of thread protecting cap slides.
The device can dismantle various sizes of thread protecting cap according to the size of the regulation distance of one vice card watt 1, substantially reduce
The labor intensity that worker single-handedly dismantles, improve the removal efficiency of drilling rod thread protecting cap.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structural side view of the present utility model.
Embodiment
Narration in detail is made to structural principle of the present utility model and operation principle below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, a kind of Handheld type drilling rod thread protecting cap provision for disengagement of the utility model, it includes being used for around brill
The slips piece 1 of bar thread protecting cap, the studs 2 for connecting two slips pieces, shell body 3, the small tooth for being installed on fixation on slips piece 1
Yielding coupling 5, stepper motor 6 and the switch 7 of controlled motor rotating of wheel 4, connection studs 2 and stepper motor 6.
Handheld type drilling rod thread protecting cap provision for disengagement provided by the utility model, pass through two pairs of lists being fixed on slips piece 1
To little gear 4, when dismantling thread protecting cap, startup power supply moves slips piece 1, clamps thread protecting cap, by rotary handle, so as to protect
Silk cap quickly disassembles, and substantially increases thread protecting cap dismounting speed, while solve conventional thread protecting cap and be tightly difficult to very much dismantle
The problem of, the labor intensity of driller is reduced again, improves drilling efficiency.
The utility model can also be used for the installment work of thread protecting cap, first by starting motor push button by thread protecting cap clamping,
Then according to the direction rotary handle of installation screw thread, compared to installation thread protecting cap work by hand, the work of this utility model is more efficient,
It is laborsaving.
Dismounting principle of the present utility model：
In use, being directed to the outer end of drilling rod thread protecting cap, startup motor 6 first inverts the provision for disengagement of hand-held thread protecting cap
Button, making two slips pieces 1, to farthest position, the slips piece 1 of the design can be with for relative motion under the drive of studs 2
The various sizes of device is selected according to the size of different drilling rod thread protecting caps.Shell body 3 is enclosed on drilling rod thread protecting cap, Ran Houqi
The dynamic main story button of stepper motor 6 is the move toward one another of two width slips piece 1 until holding the outer wall of drilling rod thread protecting cap tightly.Now it is installed on
Fixation little gear 4 on two width slips pieces 1 is stuck by the outer wall of drilling rod thread protecting cap, because little gear 4 and drilling rod thread protecting cap are
First contact, and then produce sufficiently large pressure.Then the handle of provision for disengagement is rotated, according to the direction for unloading screw thread, dismantles lower bore
Bar thread protecting cap.
