Abstract
The utility model relates to a connecting structure of a drill pipe body made of composite material and a steel connector, in particular to a connecting structure of a drill pipe body and a connector which are made of two materials with larger performance difference. A conical connecting surface is arranged outside the connecting end of the pipe body of the steel connector, and a conical connecting surface corresponding to the conical connecting surface of the steel connector is arranged inside the connecting end of the pipe body of the composite material; the two conical connecting surfaces are connected by a high-strength adhesive layer; and a stainless steel combined pin passes through a through hole on the pipe body made of the composite material and a combined groove on the steel connector to connect the through hole and the steel connector. The utility model mainly solves the technical problem that parts made of two materials can not adopt a welding way. The connecting structure not only solves the connecting problem, but also has very high connecting strength and can satisfy the service performance requirement of a drill pipe.
Description
Technical field
The drill pipe body that the utility model relates between two kinds of materials that a kind of composite material drill pipe body and steel joint connecting structure, especially performance differ greatly is connected with joint.
Background technology
At present, known steel drilling rod is that steel body and steel joint form by friction welding.Body and joint material all are low-alloy steel, and both have good friction welding performance.The performance of welding back weld seam can reach the instructions for use of steel drilling rod.If drill pipe body and joint are not with a kind of material, when especially a kind of material was nonmetals, both can not adopt the method for welding that drill pipe body and joint are coupled together.Thereby there is a connectivity problem of body and joint.
The utility model content
The purpose of this utility model is to provide a kind of composite material drill pipe body and steel joint connecting structure, the parts that mainly solve two kinds of materials can not adopt the technical problem of welding manner connection, this syndeton can not only solve connectivity problem, and have very high bonding strength, can reach the functional performance requirement of drilling rod.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of composite material drill pipe body and steel joint connecting structure is characterized in that: the body link of steel joint is provided with the taper connection face outward, is provided with the taper connection face corresponding with the taper connection face of steel joint in the link pipe of composite material body; Connect by the high strength bonding layer between the two taper joint faces; Having stainless steel is connected the two with engagement groove on the steel joint in conjunction with the through hole that pin passes on the composite material body.
Described composite material drill pipe body and steel joint connecting structure is characterized in that: the taper connection face bottom of this composite material body has in conjunction with step.
Described composite material drill pipe body and steel joint connecting structure is characterized in that: the range of taper of two taper joint faces is 5 ° to 40 °.
Described composite material drill pipe body and steel joint connecting structure is characterized in that: stainless steel is 3 groups to 6 groups, 2 to 4 row in conjunction with pin, amounts to 6 to 24 in conjunction with pin, is 120 °, 90 °, 72 °, 60 ° in conjunction with the locus angle between the pin.
Described composite material drill pipe body and steel joint connecting structure is characterized in that: the external steel sleeve that is provided with of this composite material tube, steel joint and steel sleeve are by being welded to connect.
Described composite material drill pipe body and steel joint connecting structure is characterized in that: be provided with the high strength bonding layer between this steel sleeve inwall and the composite material tube wall.
Described composite material drill pipe body and steel joint connecting structure is characterized in that: have the high-abrasive material liner in this composite material body.
Described composite material drill pipe body and steel joint connecting structure is characterized in that: the external wear-resistant material layer that is provided with of this composite material tube.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model is in connection, jumper steel joint link adopts the identical structure (range of taper is from 5 ° to 40 °) of taper ratio with the composite material body, both joint faces adopt high strength bond layer bonding, use 3 groups to 6 groups (being 120 °, 90 °, 72 °, 60 ° each other), 2 to 4 row again, 6 to 24 stainless steels connect in conjunction with finger setting.The outside is with steel sleeve parcel, is connected with the method for welding between steel sleeve and the steel joint.Steel sleeve has prevented that stainless steel from losing in conjunction with the loosening of pin, prevents the contact wear and the damage of joint composite material and sleeve pipe and tong.Guaranteed on the drilling rod, during shackle, joint can bear the effect of tong.
2, of the present utility modelly can solve the steel joint of drilling rod and the connectivity problem between the composite material body, and easy to process, simple in structure.
