Abstract
The utility model provides a friction welded drill pipe structure, which includes at least one upper drill pipe and one lower drill pipe, wherein a male connector and a female connector are frictionally welded at the two end parts of each upper drill pipe respectively, a same male connector and a same female connector are frictionally welded at the two end parts of each lower drill pipe respectively, the male connectors are matched with the female connectors mutually, the male connectors are all carburized male connectors or nitrided male connectors, and the female connectors are all carburized female connectors or nitrided female connectors. The friction welded core barrel structure has the advantages that the strength of the two end parts of the upper drill pipes and the lower drill pipes is higher, the shock resistance of the drill pipe structure is improved, and the abrasion resistance of the two end parts of the upper drill pipe and the lower drill pipe can also be improved.
Description
[technical field]
The utility model relates to a kind of critical equipment of Geological Engineering construction, relates in particular to a kind of jackrod structure of friction welding.
[background technology]
Drilling rod is one of equipment indispensable in the process of Geological Engineering construction.Because that usually drills during the Geological Engineering construction is deep, requiring jackrod structure to be connected by a plurality of monomer drilling rods forms, particularly, existing jackrod structure generally by a plurality of upper drilling rods, and a plurality ofly form with the lower drilling rod of upper drilling rod coupling respectively, the both ends of upper drilling rod are flexibly connected respectively a male joint, a female joint, the both ends of lower drilling rod also are flexibly connected respectively this male joint, this female joint, and male joint and female joint are mated mutually; Wherein, upper drilling rod and lower drilling rod be in fact all the end with the steel pipe of the first screw thread, and male joint and female joint are respectively steel male joint, steel female joint; Be equipped with the second screw thread that is complementary with this first screw thread in male joint and female joint.During assembling, usually first screw in male joint and female joint and screw on the both ends of upper drilling rod, lower drilling rod; Then the coupling of the female joint on the male joint on upper drilling rod and lower drilling rod is connected, activity is mated the female joint on upper drilling rod and is connected with the male joint on lower drilling rod, thereby completes being connected of drilling rod and lower drilling rod.
In above-mentioned jackrod structure, the second Design of Screw Thread in upper drilling rod and lower two ends of drill section makes the strength decreased on drilling rod and lower drill rod end, thereby has reduced the shock resistance of jackrod structure; In order to address this problem, the quantity of strength increase strengthening its intensity, but limited because of the thickness that can increase, has been limited in the both ends that the practitioner thickeies upper drilling rod and lower drilling rod by forging the pipe mode.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of jackrod structure of friction welding, not only makes the intensity in drilling rod and lower two ends of drill section higher, has improved the shock resistance of this jackrod structure.
The utility model solves the problems of the technologies described above by the following technical programs: a kind of jackrod structure of friction welding, comprise at least one upper drilling rod and at least one lower drilling rod, the both ends of described upper drilling rod are friction welding one male joint, a female joint respectively, the both ends of described lower drilling rod are friction welding one this male joint, this female joint respectively, described male joint and female joint are mated mutually, and described male joint is carburizing male joint or nitriding male joint, and described female joint is carburizing female joint or nitriding female joint.
Further, the external surface of described male joint is provided with the first screw thread, and the inner surface of described female joint is provided with the second screw thread that matches with this first screw thread.
The beneficial effect of the jackrod structure of a kind of friction welding of the utility model is: male joint, female joint are connected in the design of upper drilling rod, lower drilling rod by friction welding, make the intensity on drilling rod and lower drill rod end higher, improved the shock resistance of this jackrod structure, and male joint is that carburizing male joint or nitriding male joint, female joint are the setting of carburizing female joint or nitriding female joint, can improve the abrasion resistance of upper drilling rod and lower two ends of drill section.
[description of drawings]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the schematic diagram of the jackrod structure of a kind of friction welding of the utility model.
Fig. 2 is the exploded view of the jackrod structure of a kind of friction welding of the utility model.
[specific embodiment]
Please in conjunction with consulting Fig. 1 and Fig. 2, the jackrod structure of a kind of friction welding of the utility model, comprise at least one upper drilling rod 1 and at least one lower drilling rod 2, the both ends of described upper drilling rod 1 are friction welding one male joint 3, a female joint 4 respectively, the both ends of described lower drilling rod 2 are friction welding one this male joint 3, this female joint 4 respectively, described male joint 3 is mated mutually with female joint 4, and described male joint 3 is carburizing male joint or nitriding male joint, and described female joint 4 is carburizing female joint or nitriding female joint.And in the present embodiment, the external surface of male joint 3 is provided with the first screw thread 31, and the inner surface of female joint 4 is provided with the second screw thread 41 that matches with this first screw thread 31, and male joint 3 screws and is connected by this first screw thread 31 that cooperatively interacts, the second screw thread 41 with female joint 4.
During the utility model assembling, only need the male joint 3 on upper drilling rod 1 and female joint 4 on lower drilling rod 2 are screwed to be connected (as shown in Figure 1) or 2 male joint 3 on the female joint 4 on upper drilling rod 1 and lower drilling rod is screwed to be connected (not shown), just can complete being connected of drilling rod 1 and lower drilling rod 2.
In the utility model, male joint, female joint are connected in the design of upper drilling rod, lower drilling rod by friction welding, make the intensity on drilling rod and lower drill rod end higher, improved the shock resistance of this jackrod structure, and male joint is that carburizing male joint or nitriding male joint, female joint are the setting of carburizing female joint or nitriding female joint, can improve the abrasion resistance of upper drilling rod and lower two ends of drill section.
