Abstract
The utility model discloses a drill rod clamping bi-directional joint which comprises a cylindrical joint main body (1). A through hole is formed inside the joint main body (1), a plurality of clamping grooves (3) which are evenly distributed are formed in the circumferential face of the right end of the joint main body (1), a clamping shaft (5) is formed between any two adjacent clamping grooves (3), and the structure of the circumferential face of the left end of the joint main body (1) is identical with that of the circumferential face of the right end of the joint main body (1). The drill rod clamping bi-directional joint has the advantages of not only being simple in structure and low in cost, but also being stable and solid in connection, not easy to damage, high in safety and reliability and long in service life.
Description
Technical field
The utility model relates to a kind of oil drilling machine accessory, specifically is that a kind of drilling rod for jointed rod tightens two-way joint.
Background technology
Because drilling rod in use, be subjected to bigger bending moment force and various resistance, the drilling rod connector very easily is subjected to the effect of power and damages, drilling rod connector in the past adopts mostly and is threaded, and screw thread very easily destroys under the moment loading of drilling rod, causes to connect to lose efficacy, have only the connector of replacing could continue to use, not only increase cost, when changing, also taken time and effort, influenced drilling efficiency.
The utility model content
Problem to be solved in the utility model is: provide a kind of drilling rod to tighten two-way joint, be used for solving the problem that drilling rod jointing connecting portion was fragile in the past, cost is high.
The technical scheme that the utility model provides is: drilling rod tightens two-way joint, comprise columniform adapter body, adapter body inside is provided with through hole, the periphery of described adapter body right-hand member is provided with a plurality of equally distributed clamping slots, form clamping shaft between any two adjacent clamping slots, the periphery structure of the periphery of described adapter body left end and adapter body right-hand member is identical.Drilling rod tightens two-way joint when being connected with drilling rod; the drilling rod connecting portion is provided with clamping slot and the clamping shaft structure that matches with joint left and right sides end face; the two is connected, and finishes chucking by clamping slot and clamping shaft and is connected, and this connected mode not only intensity is big; connect stable, firm; and not fragile, can well protect the connecting portion of joint and drilling rod, not only safe and reliable; and protectiveness is good, long service life.
The external diameter of described clamping shaft is less than the external diameter of adapter body, and described clamping shaft and adapter body periphery junction form locating platform.When joint is connected with drilling rod, by the two axial dimension position of locating platform centering, reach accurate assembling.
Described clamping shaft periphery also is provided with positioning screw hole.Have the screwed hole with the positioning screw hole pairing in the drilling rod relevant position, screw with drilling rod and joint axial restraint, is used for preventing that drilling rod and joint from occurring endwisely slipping and break down by screwed hole and positioning screw hole, has improved safety.
Described adapter body periphery also is provided with rises as high as the banks.When loading and unloading, be clamped in the place that rises as high as the banks with external tool, thereby by the instrument swivel, not only made things convenient for loading and unloading, and can also well protect the joint external surface not to be destroyed.
Described rising as high as the banks is provided with 2 altogether, is circularly and evenly distributed each other.Instrument can symmetry be clamped in the rising as high as the banks of joint when clamping, and makes the joint stress balance, and the workload that can reduce a staff guarantees that joint can not occur tilting, and can prevent that instrument from use skidding in rotation process.
Two ends, the described adapter body left and right sides are respectively equipped with 8 clamping slots.Drilling rod tightens two-way joint when chucking connects, reaching chucking by the cooperation between clamping slot and the clamping shaft connects, drilling rod arrives joint with carry-over moment in the course of the work, if clamping slot is very few, then the moment that is subjected to of each clamping slot is very big, very easily damages, so adopt a plurality of clamping slots to reduce the moment loading that each clamping slot is subjected to, and 8 be a desirable number, can guarantee maximum bonding strength.
Described adapter body adopts the 30cr material.30cr uses under quality adjustment condition usually, also can after normalizing, use, for the manufacture of under wearing and tearing and the friction condition or the important parts of under great impact load, working, it has very high hardness and resistance, adapter body adopts 30cr not only can satisfy its need of work, can also prolong its application life greatly.
Advantage of the present utility model is: this drilling rod of the utility model design tightens two-way joint, not only simple in structure, cost is low, and connect stable, firmly, not fragile, safety and reliability height, long service life.

Label among the figure is expressed as respectively: 1, adapter body; 2, locating platform; 3, clamping slot; 4, positioning screw hole; 5, clamping shaft; 6, rise as high as the banks.
The specific embodiment
Embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, drilling rod tightens two-way joint, comprise columniform adapter body 1, adapter body 1 inside is provided with through hole, the periphery of described adapter body 1 right-hand member is provided with a plurality of equally distributed clamping slots 3, form clamping shaft 5 between any two adjacent clamping slots 3, the periphery structure of the periphery of described adapter body 1 left end and adapter body 1 right-hand member is identical.
The external diameter of described clamping shaft 5 is less than the external diameter of adapter body 1, and described clamping shaft 5 forms locating platform 2 with adapter body 1 periphery junction.
Described clamping shaft 5 peripheries also are provided with positioning screw hole 4.
Described adapter body 1 periphery also is provided with rises as high as the banks 6.
Described rising as high as the banks 6 is provided with 2 altogether, is circularly and evenly distributed each other.
Two ends, described adapter body 1 left and right sides are respectively equipped with 8 clamping slots 3.
Described adapter body 1 adopts the 30cr material.
In use, joint cooperates chucking to be connected by the structure of two ends clamping slot 3 and clamping shaft 5 with drilling rod, and is not only simple in structure, be connected firmly, and also not fragile, long service life.
In cargo handling process, the staff can be sandwiched in instrument and rise as high as the banks 6, conveniently assemble and disassemble; and can not damage by the butt joint external surface; the staff is the joint stress equalization when utilizing instrument to load and unload, and the situation that joint fractures or is out of shape can not occur, fabulous protection joint.
The adding of locating platform 2 and positioning screw hole 4 makes that the link position of joint and drilling rod is accurate more, firm, and safety and assembling degree all improve greatly.
Can well realize the utility model as mentioned above.
