Abstract
The utility model belongs to a gripping mechanism which fixes the drilling tool or the annular tube at the mine mouth when replacing the drilling tool or the cementing in the drilling engineering, in particular to a disk type pneumatic slip which comprises a slip fitting to a slip seat. The inner wall of the confined slip seat is in conical surface, and three symmetrical cuneate slips at least are arranged copulately in the truncated cone cavity of the slip seat. The back sides of the slips cooperate to the conical surface of the slip seat, and the right sides of the slips are in cylinder arc surface. A top plate with a centre hole are supported respectively by the piston rods' ends of three upstanding master cylinders at least. The catch plates fixed to the top of the cuneate slips are clamped respectively on the top face of the top plate, and the piston rods of the horizontal countercylinders fixed on the top plate respectively are connected to the cuneate slips. The utility model clamps the drilling tool automatically by the mechanism and doen't need to move the lift sub, and one person can finish replacing the drill head or the lowering and the lifting work of the drilling tool. The operation is convenient and safe, the working efficiency is high, and the labor intensity is reduced.
Description
Technical field
The utility model belongs in drilling engineering when changing drilling tool or well cementation, at well head with drilling tool or the fixing gripping mechanism, particularly disc type air operated slips of sleeve pipe.
Background technology
In drilling operation course, for more bit change and well cementation etc. need, to carry usually and bore operation, promptly the drilling tool in the well is put forward more bit change; Or with sleeve pipe G.I.H cementing well.In these operations, button or during shackle on each joint drilling tool all carries out the drilling tool of G.I.H at well head, its upper end all will hang on the elevator that is sitting in well head, with elevator drilling tool is sling, wait stand on the derrick another the joint drilling tool winch to well head, on link closely, on carry the elevator of removing well head, drilling tool G.I.H (its upper end still is sitting on the elevator) with connecting hangs over the hook earrings on the elevator of removing previously, hangs another joint drilling tool again and comes to carry out to link to connect.Above-mentioned work needs two people to operate elevator and earrings all the time, and each elevator weight is all more than kilogram up to a hundred, and it is very painstaking to operate.Operate not only dangerous but also inconvenient, time-consuming.
The utility model content
The purpose of this utility model is to provide a kind of disc type air operated slips, can block drilling tool automatically by machinery, do not need to move elevator, there is a people just can finish the transferring and lifting work of drilling tool, sleeve pipe of bit change or well cementing operation, and it is easy to operate, safety, high efficiency reduces labor intensity.
The purpose of this utility model is achieved in that a kind of disc type air operated slips, comprise the slips that cooperates with slip spider, its inwall of slip spider of sealing is taper seat, in the cavity of slip spider truncated cone, cooperate at least three dovetail slips that symmetry is installed, match with the taper seat of slip spider in the back side of slips, the front of slips is the cylinder cambered surface, piston rod end by at least 3 upright master cylinders is being supported the top board that has centre bore respectively, the affixed clamp in dovetail slip top is stuck on the top board end face, and the piston rod that is separately fixed at the horizontal countercylinder on the top board is connecting dovetail slip.
The utility model is arranged on the well head rotating disk, moves at any time and is not subjected to spatial constraints, makes the cone-shaped hole of slip spider and well head concentric, and slips is trapped among the center with drilling tool.Carry, when descending drilling tool, open admission valve and make the air inlet of master cylinder bottom when needs, it is up that piston rod promotes top board, and slips is also up thereupon; The also air inlet of countercylinder this moment, its piston rod promote slips and outwards move, and slips leaves drilling tool and abdicates the space, makes the drilling tool upstream or downstream.After the drilling tool operation puts in place, open admission valve and make the air inlet of master cylinder top, piston rod drives top board and moves down, the countercylinder air inlet of installing on the top board, promote slips simultaneously and move to the center, block drilling tool, the back side of slips cooperates with the taper seat of slip spider, the own wt of drilling tool and the gradient of taper seat are had an effect, and drilling tool firmly can be blocked.When drilling tool at button on the well head or after shackle finishes, carry again, down during drilling tool, can repeat above-mentioned course of action again.The utility model blocks drilling tool automatically with machinery, does not need to move elevator, has a people just can finish the transferring and lifting work of drilling tool of bit change or well cementing operation.And easy and safe to operate, high efficiency has alleviated labour intensity significantly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the main TV structure schematic diagram of the utility model embodiment 1;
Fig. 2 is the A-A sectional structure schematic diagram among Fig. 1;
Fig. 3 is the main TV structure schematic diagram of the utility model embodiment 2.
The specific embodiment
A kind of disc type air operated slips, embodiment 1 as shown in Figure 1 and Figure 2, comprise the slips 5 that cooperates with slip spider 1, the slip spider 1 of sealing, the slip spider 1 that its symmetrical parts become to seal by bolts assemblies, the inwall of sealing slip spider 1 is taper seat, cooperates at least three dovetail slips 5 that symmetry is installed in the cavity of slip spider 1 truncated cone, match with the taper seat of slip spider 1 in the back side of slips 5, the front of dovetail slip 5 is the cylinder cambered surface.The uniform cross section that is being provided with is zigzag flange on the cylinder cambered surface in dovetail slip 5 fronts.When dovetail slip 5 zigzag flanges contact with drilling tool, can produce bigger frictional force, drilling tool is firmly blocked.The uniform cross section that is being provided with is the obtuse angle projection on the taper seat of slip spider 1, can reduce the stroke height of dovetail slip 5 like this.By at least 3 upright master cylinders 2, its underpart is fixedly mounted on the slip spider 1, the piston rod end on its top is being supported the top board 3 that has centre bore respectively, top board 3 is a disc, the affixed clamp in dovetail slip 5 tops is stuck on top board 3 end faces, and the piston rod that is separately fixed at the horizontal countercylinder 4 on the top board 3 is connecting dovetail slip 5.Opening part at disc top board 3 is installed with valve 6, and a side of valve 6 is hinged on the opening edge of top board 3, and the opposite side of valve 6 is fixed on the another side of top board 3 openings by screw.Embodiment 2 as shown in Figure 3, top board 3 is a square, at the opening part of square top board 3 valve 6 is installed, and the hinged ear of symmetry is being set on the side of square top board 3 openings, the valve 6 that has positioning edge groove 7 is hinged on the top board 3 by hinged ear.When needs dismounting dovetail slip 5, the valve on the top board 36 is taken apart, dovetail slip 5 can be drawn off.
