Abstract
The utility model discloses a dual-cylinder air operated slip which consists of two cylinders, a slip seat, rotary shafts, connection rods and a slip body, wherein the slip seat is a rectangular shell, the bottom of the slip seat is provided with flange holes, the rotary shafts are respectively hinged on two sides of the top of the slip seat, two cylinder support seats that are arranged in staggered manner are respectively arranged on the front side and the rear side of the bottom of the slip seat, the cylinder body ends of the two cylinders are respectively hinged with the two cylinder support seats, piston rods of the two cylinders are respectively pivoted with cranks of the rotary shafts, lifting lugs are respectively pivoted on the left side and the right side at the upper end of the slip body through bolts, each lifting lug and the rotary shaft on the same side are hinged through the connection rod, the slip body consists of two pieces, is conic externally, is matched with an inner conic hole of the slip seat, and is located on inner steps of the slip seat so as to support the slip to clamp a drilling tool, and the center of the slip body is provided with a cylindrical hole with jaws. The air operated slip adopts the dual cylinders which move simultaneously, thus guaranteeing that the slip moves synchronously; and the slip body can be replaced, thus greatly enlarging the application range of the slip.
Description
Technical field
The utility model relate to a kind of in drilling engineering the clamping device of unloading when changing of well head drilling tool, particularly a kind of pair of cylinder air operated slips.
Background technology
In drilling process, change drilling tool, processing accident etc. and all need remove drilling rod, the unloading drilling rod ring that is absolutely necessary.At this moment, at first to clamp drilling tool.In job site in the past, usually need manual work to move slips, the degree of tightness of slips also needs manpower control fully, causes working strength of workers to increase, and efficient reduces, and the workman often is under the drilling tool, has potential safety hazard.Utility model patent ZL200420038781.5 discloses a kind of air operated slips of single elevator; Used pneumatic control, improved automaticity, but single cylinder control slips has only been used in this design; Cause the asynchronism of slips motion easily, especially two with upper slips.For this reason, through improving, it is reliable to design a kind of structural safety, and automaticity is high, and slips applied widely is that realistic meaning is arranged very much.
Summary of the invention
The purpose of the utility model is to solve the single cylinder control slips that ZL200420038781.5 exists, and causes the shortcoming of the asynchronism of slips motion easily, and a kind of pair of cylinder air operated slips is provided.
The utility model is made up of cylinder, slip spider, rotating shaft, connecting rod and slips body, and slip spider is a rectangular housing, and flange hole is arranged at the bottom of slip spider; Be used for fixing at well head, the hinged rotating shaft in both sides, slip spider top, side is respectively arranged with the staggered cylinder saddle in position before and after the slip spider top; Two cylinder block ends are hinged with two cylinder saddles respectively, and the piston rod of two cylinders articulates with the crank of rotating shaft respectively, and the left and right sides, slips body upper end is articulated with hanger respectively with latch; Articulated linkage between the rotating shaft of each hanger and homonymy, the slips body is formed by two, and its outside is conical and cooperates with the female cone hole of slip spider; Has certain guide character; And be seated on the interior step of slip spider, for slips chucking drilling tool provides support, the cylindrical hole with pincers tooth is offered at slips body center.
The course of work and the principle of the utility model are:
The flexible rotation that drives rotating shaft of the piston rod of cylinder is transformed into moving up and down of slips body through crank-rotating shaft-linkage with gyration.
The slips body is formed by two, and it is conical that its outside is, and cooperates with the female cone hole of slip spider, has certain guide character, and is seated on the interior step of slip spider, for slips chucking drilling tool provides support.
Two-piece type slips body is connected with latch with connecting rod, and convenient disassembly for the drilling tool of various outer diameter, can be changed the model of slips body rapidly, has enlarged the scope of application of this type air operated slips, has saved labour hour.
The beneficial effect of the utility model:
1, the utility model adopts two cylinders to move simultaneously, drives the elevating movement of slips body.Action when realizing two cylinder has designed the synchronization action control loop, is made up of cylinder, two one-way throttle valves, reversal valve and sources of the gas.The conversion that cylinder piston rod is flexible is realized through reversal valve in this loop, and two one-way throttle valves have mainly guaranteed two reliabilities that cylinder is synchronized with the movement through regulating air-flow velocity.Simple in structure, safe and reliable.
2, the slips body is conical by two outsides, and is inner for having the cylindrical hole composition that clamp tooth, and the slips body is removable, is used for the drilling tool of clamping different-diameter.Because the slips body uses pin to connect, convenient disassembly does not need special instrument, has improved the scope of application of slips greatly.

The specific embodiment
See also illustrated in figures 1 and 2ly, present embodiment is made up of cylinder 1, slip spider 2, rotating shaft 3, connecting rod 4 and slips body 5, and slip spider 2 is rectangular housing; Flange hole 6 is arranged at the bottom of slip spider 2, is used for fixing at well head the hinged rotating shaft 3 in both sides, slip spider 2 top; It is hinged with two cylinder saddles 7 respectively that side is respectively arranged with staggered 7, two cylinder 1 cylinder body end of cylinder saddle in position before and after slip spider 2 tops, and the piston rod of two cylinders 1 articulates with the crank 31 of rotating shaft 3 respectively; The left and right sides, slips body 5 upper end is articulated with hanger 8 respectively with latch 51; Articulated linkage 4 between the rotating shaft 3 of each hanger 8 and homonymy, slips body 5 is formed by two, and its outside is conical and cooperates with the female cone hole 21 of slip spider 2; Has certain guide character; Slips body 5 is seated on the interior step 22 of slip spider 2, and for slips chucking drilling tool provides support, the cylindrical hole 52 with pincers tooth is offered at slips body 5 centers.
The course of work and the principle of the utility model are:
The flexible rotation that drives rotating shaft 3 of the piston rod of cylinder 1,---rotating shaft---linkage is transformed into moving up and down of slips body 5 with gyration through crank.
Two-piece type slips body 5 is connected with latch 51 with connecting rod 4 mechanisms, and convenient disassembly for the drilling tool of various outer diameter, can be changed the model of slips body 5 rapidly, has enlarged the scope of application of this type air operated slips, has saved labour hour.
This utility model adopts two cylinders 1 to move simultaneously, drives the elevating movement of slips body 5.Action when realizing two cylinder has designed the synchronization action control loop, is made up of cylinder 1, two one-way throttle valves 9, reversal valve 10 and sources of the gas 11.The conversion that cylinder 1 piston rod is flexible is realized through reversal valve 10 in this loop, and two one-way throttle valves 9 have mainly guaranteed two reliabilities that cylinder 1 is synchronized with the movement through regulating air-flow velocity.Simple in structure, safe and reliable.
