Abstract
The utility model discloses a device for connecting a single drill pipe by a drilling platform. A mouse hole is formed at one side of a drilling hole; the drill pipe is arranged inside the mouse hole and comprises a zip fastener, a semicircular cylinder and a bump; the lower part of the semicircular cylinder is connected with the mouse hole in a hinge manner; the semicircular cylinder is vertically arranged on the mouse hole; the bump is fixed inside the semicircular cylinder; an open window is arranged at the upper part of the semicircular cylinder; the zip fastener is suspended on a hoisting ring in a penetrating manner; a loop at the lower end of the zip fastener sleeves a square drill pipe; the zip fastener passes through the open window at the upper part of the semicircular cylinder; the hoisting ring is connected to an air winch; a pin roller is arranged at the open window at the upper part of the semicircular cylinder; the zip fastener is arranged below the pin roller; and the air winch is lifted, so that the square drill pipe moves to the mouse hole to be accurately buckled with the drill pipe. Therefore, an ideal device for connecting the single drill pipe by the drilling platform is provided for drilling operation. The device is high in automatic degree and high in work efficiency; the potential safety hazard is removed; the labor intensity of a worker is reduced; and the device has significant economic benefit and social benefit.
Description
Technical field
The utility model belongs to the equipment of the on-the-spot use of oil drilling, is a kind of offshore boring island device that makes up a joint.
Background technology
In drilling well stacks process, the kelly bar that needs to be in the pithead position top moves to the rat hole place, then with after drilling rod make-up in rat hole is connected drilling rod is sling, and this process is called at the scene and makes up a joint.The kelly bar that to be in pithead position top of making up a joint at present moves to the rat hole place, firmly to pull kelly bar to make its joint align tool joint box in rat hole after hooking kelly bar by 2-3 human hook, due to factor impacts such as large, inertia firmly, kelly bar make-up difficulty needs repeated multiple timesly just can complete make-up sometimes.Because drilling floor surface often has mud, easily skid again, make up a joint very because of difficulty, exist the possibility of potential safety hazard to increase.Therefore, this way mechanization degree that manually pulls kelly bar to realize displacement is low, causes labor strength large, and inefficiency does not have safety guarantee.
Summary of the invention
The purpose of this utility model is a kind of offshore boring island of design device that makes up a joint, and makes up a joint with mechanical device, eliminates safe hidden trouble, and increases work efficiency, and reduces labor intensity.
The purpose of this utility model is achieved in that rat hole is in a side of well-drilling borehole, drilling rod is in rat hole, comprise slide fastener, semicircular cylinder, projection, the bottom of semicircular cylinder is connected with the rat hole hinge type, and semicircular cylinder erects on rat hole, the interior fixedly projection of semicircular cylinder, window in semicircular cylinder top, slide fastener is worn and hung on suspension ring, and the lower loop snare of slide fastener is lived kelly bar, slide fastener passes windowing of semicircular cylinder top, and suspension ring are connected on pneumatic hoist.
Roller is installed at the place of windowing on semicircular cylinder top, and slide fastener is in the below of roller.
The beneficial effects of the utility model are: pneumatic hoist promotes and can make kelly bar move to rat hole place and the accurate make-up of drilling rod, therefore, the utility model provides a kind of desirable offshore boring island device that makes up a joint for drillng operation, automaticity is high, high efficiency, eliminate potential safety hazard, alleviated labor strength, had significant economic benefit and social benefit.
Description of drawings
Accompanying drawing 1 is assembling drawing of the present utility model.
Accompanying drawing 2 is right views of part 7 in accompanying drawing 1.
Accompanying drawing 3 is top views of part 7 in accompanying drawing 1.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
as seen from the figure, rat hole 10 is in a side of well-drilling borehole 9, rat hole 10, well-drilling borehole 9 is under offshore boring island, drilling rod 11 is in 10 li of rat holes, semicircular cylinder 7 is half of cylinder, the bottom of semicircular cylinder 7 is connected with rat hole 10 hinge types, semicircular cylinder 7 erects on rat hole 10, semicircular cylinder 7 can rotate around the bearing pin that hinge type connects, make semicircular cylinder 7 can erect also to fall down, use when facilitating kelly bar 4 to be connected with drill rod thread on liquid gas tong and link closely, the interior fixedly projection 8 of semicircular cylinder 7, play gear and hold up kelly bar 4, the conical external screw thread of guarantor's drilling rod 4 lower ends can be aimed at the conical internal thread of drilling rod 11 under heeling condition, semicircular cylinder 7 tops window 6, slide fastener 3 is worn and is hung on suspension ring 2, the lower loop snare of slide fastener 3 is lived kelly bar 4, what slide fastener 3 passed semicircular cylinder 7 tops windows 6, suspension ring 2 are connected on pneumatic hoist 1.Roller 5 is installed at uplifting window 6 places on semicircular cylinder 7 tops, and roller 5 two ends are connected on semicircular cylinder 7, can roll but can not come off, slide fastener 3 is in the below of roller 5, Zola's chain 3 is in contact with it when upwards walking, and roller 5 produces and rolls, can reduce slide fastener 3 wearing and tearing.
When drilling rod 11 is in 10 li of rat holes, be fixed to the middle position by the device of design, in order to dock with kelly bar 4.
During lower drilling rod work, after the drilling rod connecting thread of 9 li of kelly bar 4 and well-drilling boreholes is thrown off, the lower loop snare of slide fastener 3 is lived kelly bar 4 (as shown in Figure 1).Lift chain 3 on pneumatic hoist 1, slide fastener 3 is pulled to kelly bar 4 position as shown in Figure 1 from the top of well-drilling borehole 9.Slowly transfer pneumatic hoist 1, kelly bar 4 lower taper external screw threads will enter in the internal thread on drilling rod 11 tops, achieve a butt joint, and do not need 2-3 people to pull the kelly bar docking, and are fast and convenient.Kelly bar 4 with transfer 2 pairs of semicircular cylinders 7 of suspension ring after drilling rod 11 is aimed at and apply lateral force, make its overturning to the right, just can rotate kelly bar 4 jointed rods 11 with hydraulic tongs.
