Utility model content
In order to solve the above technical problems, the utility model provides a kind of SDHL type big load drill pipe slip, can be used for surpassing
Heavy duty service.
The technical solution adopted in the utility model is:
A kind of SDHL type big load drill pipe slip, including slips body, there is dental lamina slot on the slips body, on the dental lamina slot
Equipped with slip dog and support ring, the slip dog is fixedly mounted on slips body by dental lamina slot, and the support ring is shared
Two, it is respectively and fixedly installed to slip dog middle part and bottom.
Further, the slips body includes verso slips, middle page slips and recto slips, the verso slips, middle page
Slips and recto slips are linked together by connecting pin.
Further, it is provided with dental lamina baffle ring on the slips body, is fixedly mounted on slips body by baffle ring screw.
Further, slips hand handle is installed on the slips body, the slips hand handle include left handgrip, right handgrip and in
Hand handle, slips body head are provided with hand handle pin hole, the left handgrip, right handgrip and middle hand handle pass through hand handle pin respectively with
Verso slips, recto slips and middle page slips link together.
Further, the tapered Openworks shape in the slips body back side.
Further, split pin is mounted on the connecting pin and hand handle pin.
The beneficial effects of the utility model are: 1, two support ring supporting slip dental lamina, plays dispersion slip dog stress
Effect, and then increase slips and can bear the range of load, the load that the maximum of slips can be born reaches 750 US
Tons is suitable for global most deep drilling well operations at present；2, SDHL type drill pipe slip is compact-sized, outer dimension and conventional drill rod card
It is watt similar, it is compact and flexible, it is easy to use；3, the tapered Openworks shape in the slips body back side passes through card when drill pipe slip clamping drilling rod
Watt dental lamina embraces drilling rod, and the slips back side is contacted with rotary bushing liner inner conical surface taper, when by drilling rod be self-possessed down-force when bore
Face contact forces slip dog tightly to embrace drilling rod and will not skid.
