Abstract
The utility model provides a spin-up guiding device used in oil casing and oil pipe, which comprises two semi-cylindrical support rings and two semi-circular sheaths arranged on the inner side of the support rings. One side of the two semi-circular sheaths are connected through a hinge, and the other opening side is provided with a locking device. The intracavity of the sheath comprises an import cylinder and an import cone. The opening end of the support ring is fixed with the locking device. The utility model has the advantages that: the spin-up guiding device adopts the sheath that is made of wearing engineering plastics with low hardness, which can effectively protect pipe end. The sheaths are supported by steel support rings, which can bear the radial force formed by the swing of steel tube. Adopting collision locking device with wide surface contact can provide sufficient working strength, and the shutting or opening of the spin-up guiding device can be easily accomplished. The handles of the two sides can be vertical structure or horizontal structure, and the handles have the advantages of simple operation and repeated use.
Description
Technical field
The utility model relates to petroleum casing pipe and oil pipe assembling, especially for the instrument of the special thread assembling that has the forward end seal face.
Background technology
Petroleum casing pipe and oil pipe are gone into the well and assembled is the committed step of completion and production petroleum and natural gas.At present, because the field condition of oil, gas well limits, and reason such as staff's negligence of operation, the front end of sleeve pipe or oil pipe pin thread and the box cupling mouth of last branch casing or oil pipe are bumped, thereby cause the damage of pipe end.Particularly have than the torque resistant shoulder of high manufacturing accuracy and the special joint sleeve and the oil pipe of sealing surface for the pin thread front end, any slight colliding with all can cause whole even number branch casing or oil pipe to scrap because of damage.Simultaneously, for sleeve pipe and the oil pipe of pitch, be easy to take place when going up button at the scene because the accident that thread alternating causes sleeve pipe or oil pipe to damage less than per inch 5 teeth.Attempt to solve this problem by the operation or other the traditional measures that require the modular working personnel, its result also produces little effect.
Summary of the invention
The purpose of this utility model provides on a kind of rational in infrastructure, easy and simple to handle, the sleeve pipe that can reuse, can effectively protect torque resistant shoulder, sealing surface and the screw thread of sleeve pipe pipe end and the oil pipe and buckles guide, solves because of colliding with or thread alternating causes sleeve pipe or oil pipe to scrap the generation of accident.
In order to address the above problem, the technical solution of the utility model provides going up that a kind of petroleum casing pipe and oil pipe use and buckles guide, it is characterized in that guide is the support ring 1 that includes two semi-cylindrical form, the sheath 2 that is fixed on two semi-ring shapes on the described support ring inboard, one side of the support ring 1 of described two semi-cylindrical form is connected through the hinge, and its another open side is provided with locker.
Described locker comprises the bearing 5 that is separately fixed at support ring 1 openend and fixing snap close 7, and movable snap close 6 is movably connected on the bearing 5 by spring 4.
Effect of the present utility model is with wear-resisting and sheath that nylon that hardness is lower or close material are made can design and manufacture suitable shape according to different sleeve pipe and oil pipes, can protect pipe end effectively; The support ring of steel is supporting sheath can bear the radial load that forms owing to the steel pipe swing; Adopt the collision locker of wide contact, enough working strengths can be provided, and can be easy to finish closing up (entering duty) or opening (unloading after finishing guiding) of button guide; The handle of both sides can be selected vertical formula or horizontal type structure, uses with the operator who makes things convenient for the different operating custom, have easy and simple to handle, reusable characteristics.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
As shown in Figures 1 to 4, this petroleum casing pipe and oil pipe are used goes up the steel support ring 1 buckle guide and to include two semi-cylindrical form, the nylon sheath wire 2 that is fixed on two semi-ring shapes on the described support ring inboard, in the both sides of support ring handle 3 is housed.One side of the support ring 1 of described two semi-cylindrical form is connected through the hinge, and its another open side is provided with locker.Nylon sheath wire 2 inner chambers are made up of the importing cylinder that has cascaded surface symmetrically and the importing conical surface.Comprise the bearing 5 that is separately fixed at support ring 1 openend and fixing snap close 7 at the locker of the open side setting of support ring 1, movable snap close 6 is movably connected on the bearing 5 by spring 4.
With steel or to have with the made support ring 1 of the rigid material of the close intensity of steel be to go up buckle guide and connect main body, it is shaped as the ring cylinder of a side by hinge connection opposite side opening.The sheath 2 that nylon or other engineering plastics are made encircles in two, is fastened on the inwall of support ring 1.In opening one side of support ring 1,, one group or array locker are housed according to the different size of sleeve pipe or oil pipe.The fixedly snap close 7 of locker and bearing 5 are installed in the both sides of support ring 1 opening respectively, and movable snap close 6 is movably connected on the bearing 5 by spring 4, and the handle of vertical formula or horizontal type is equipped with in the support ring both sides.
With wear-resisting and sheath that nylon that hardness is lower or other engineering plastics are made can design and manufacture suitable shape according to different sleeve pipe and oil pipes, can protect pipe end effectively.The support ring of steel is supporting sheath can bear the radial load that forms owing to the steel pipe swing.
Locker adopts the collision locking mechanism of wide contact, and enough working strengths can be provided, and can be easy to finish closing up (entering duty) or opening (unloading after finishing guiding) of button guide, thereby has characteristics easy and simple to handle.Can select vertical formula or horizontal type structure at the handle of support ring both sides, use with the operator who makes things convenient for the different operating custom.
As shown in Figure 5, in use, will go up before the butt joint of sleeve pipe or oil pipe and buckle guide and be sleeved on coupling end, the automatic fastening of locker, on detain guide sheath inboard shoulder be close to coupling face.Sheath 2 by different size, buckle the importing conical surface of shape and pipe end shaped design and import cylinder and the male end of guiding sleeve or oil pipe is correctly entered screw thread twist and connect state, thereby can effectively protect the sealing surface and the screw thread of pipe end.When twist tap into normal condition after, the movable snap close of pulling locker can be opened and detain guide.This button guide can use aborning repeatedly.
