Specific embodiment
Referring to Fig. 1-Fig. 3, the present invention includes lifting lug 1, flap seat 2, chassis 8, control panel 6, oil cylinder 7 and one group of slips.Lifting lug
It is arranged at two, two lifting lugs are symmetrically fixed on flap seat two sides, and each lifting lug, which is equipped with, hangs slot 1-1 for hang hanging ring, hang slot as laterally
U-lag.Pin shaft 10 passes through the opening for hanging slot, by closure of openings.Pin shaft is inserted into after hanging ring 13 is linked into and hangs slot when use,
Hanging ring falls off when preventing from putting brill.Chassis is fixed on flap seat lower part, and control panel is arranged on flap seat top.Vertically-mounted oil cylinder 7
Bottom be fixed on chassis, oil cylinder is equipped with number set, and to guarantee stress balance, each oil cylinder is uniformly distributed with respect to flap seat center.Oil
The number of cylinder is advisable with 2-4 set, and two sets of oil cylinders are used in illustrated embodiment.Each cylinder piston rod is separately connected control panel, control
Disk is equipped with one group of radial groove 6-1.Flap seat is equipped with up big and down small conical bore, and one group of slips is mounted in conical bore, each to block
Watts 4 outer wall is to match arc conical surface be bonded with the conical bore of flap seat, and each slips inner wall is arc surface, after one group of slips pairing
Its inner wall constitutes the cylindrical surface with 14 diameter matches of drilling rod for mentioning brill.The taper of flap seat conical bore, which is 18 ° -22 °, to be advisable.Each slips
Top screws guide blot 5, and each guide blot is each passed through corresponding guide chute, and the inner wall of each slips is equipped with spring groove 4-
1, spring groove is interior to be equipped with spring 3, and spring uses circular open spring.It is equipped with taper sheath 9 in chassis lower part, taper sheath is used for
Enter elevator for drill-pipe stand and plays guiding role.
Referring to Fig. 4, Fig. 5, to improve the frictional force between slips and drilling rod, gear piece slot 4-2, tooth are equipped in the inner wall of slips
Film trap lower part soldering sector baffle 11, gear piece slot is interior to install slips gear piece 12, and slips gear piece is made of wear-resistant material, slips tooth
Piece inner wall is equipped with groove, and slips gear piece bottom presses fan-shaped baffle.One piece of slips gear piece is at least installed, diagram is real on every piece of slips
It applies and two slips gear piece blocks is housed on every piece of slips in example.Split assembled structure between slips gear piece and slips is convenient to abrasion
Slips gear piece is replaced.The number of one group of slips is 3-6 block, and the number of slips is four pieces in illustrated embodiment.Pass through replacement
What slips can be applicable in different-diameter drilling rod puts brill.
The course of work of the invention is as follows: when drilling rod enters elevator, the piston rod of two oil cylinders stretches out, and control panel moves up,
Each slips under the action of the spring, radially expands while moving up with control panel along the guide groove in control panel, slips diameter
To after complete open, diameter of bore substantially exceeds clamped drilling rod outer diameter, guarantees that clamped drilling rod can smoothly enter into elevator；By hanging ring
Hanging on slot for flap seat two sides is hung over, the pin shaft hole on lifting lug is inserted into pin shaft, and two Vertical Cylinders piston rods retract, in control panel
Effect lower slips are radially contracted, and the circular cone internal surface of hole of the slips back side and flap seat is taper-face contact, and flap seat inner surface generates at this time
Positive pressure rubbing between the normal pressure and drilling rod of drilling rod radial direction is acted on by the Orthogonal Decomposition of power in the slips back side
It wipes power and is greater than (or being equal to) drilling rod gravity, achieve the purpose that clamping drilling rod mentions brill.And drilling rod is heavier, the power of slips holding drill pipe is got over
Greatly, folder is tighter.
