Abstract
The utility model discloses an antiskid protecting joint which mainly solves the problem that the prior protecting joint relatively slides, and is characterized in that the outer surface of a protecting joint main body (1) is axially and uniformly provided with three grooves (2). The antiskid protecting joint not only eliminates the phenomenon of relative slide, but also has the advantage of simple structure.
Description
Technical field:
The utility model relates to the oil field and creeps into the used protection joint of kelly bar in the field, especially anti-skidding protection joint.
Background technology:
In the field of creeping into; in order to make bating, increase drill string length by making up a joint, in the process of making up a joint in the drilling well; protection joint under the kelly bar will be born the effect that repeats to unload the drilling tool screw thread; during last shackle because liquid pneumatic drill tool pincers and joint external surface before holding tightly, produce relative slip, through repeatedly going up shackle; joint surface is degraded; the fittings body external diameter diminishes, and can't repair use again after the screw thread wearing and tearing, causes bigger waste.
The utility model content:
In order to solve the problem that existing protection joint slides relatively, the utility model provides a kind of anti-skidding protection joint, and this anti-skidding protection joint is not only eliminated relative sliding phenomenon, and has characteristic of simple structure.
The technical solution of the utility model is: this anti-skidding protection joint comprises the protection adapter body, and protection adapter body external surface axially evenly has 3 grooves.
The utlity model has following beneficial effect: this anti-skidding protection joint is owing to take such scheme; by Surface Machining 3 grooves; when the loading and unloading drilling rod; the tooth that bores pincers enters in the groove; when rotating, loading and unloading drilling rod button can effectively prevent to bore pincers tooth and the relative slip of protecting the adapter body surface like this; thereby it is protected adapter body, and simple in structure.Though it is simple in structure; but the benefit of bringing is big; bore pincers tooth and the relative slip of protecting adapter body because of having eliminated; thereby reduce the wearing and tearing and the corrosion of protection adapter body; also just reduced the frequency of replacing and restoration and protection adapter body; raw material have been saved, the final purpose that realizes reducing drilling cost.This anti-skidding protection joint is not only eliminated relative sliding phenomenon thus, and has characteristic of simple structure.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-protection adapter body among the figure, the 2-groove.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this anti-skidding protection joint comprises protection adapter body 1, and screw thread leaves certain distance and axially evenly has 3 grooves 2 about protection adapter body 1 external surface.Guarantee to repeat to repair use after the screw thread wearing and tearing.Owing to axially have 3 grooves 2 at protection adapter body external surface; when the loading and unloading drilling rod; the tooth that bores pincers enters in the groove; when rotating, loading and unloading drilling rod button can effectively prevent to bore pincers tooth and the relative slip of protecting adapter body 1 surface like this; thereby protected adapter body 1; and simple in structure, long service life.Though it is simple in structure; but the benefit of bringing is big; bore pincers tooth and the relative slip of protecting adapter body 1 because of having eliminated; thereby reduce the wearing and tearing and the corrosion of protection adapter body 1; also just reduced the frequency of replacing and restoration and protection adapter body 1; raw material have been saved, the final purpose that realizes reducing drilling cost.This anti-skidding protection joint is not only eliminated relative sliding phenomenon thus, and has characteristic of simple structure.
