Abstract
The utility model provides a friction welded sleeve structure, which includes multiple sleeves, wherein a male connector and a female connector are frictionally welded at the two end parts of each sleeve respectively, the male connectors are matched with the female connectors mutually, the sleeves are connected through matching of the male connectors and the female connectors, 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 sleeve structure has the advantages that the strength of the end parts of the sleeves is higher, and the wall thickness of the sleeves is not required to be increased, so that the problems brought by increase of the wall thickness of the sleeves is avoided.
Description
[technical field]
The utility model relates to the working sleeve structure of a kind of Geological Engineering, relates in particular to a kind of sleeve structure of friction welding.
[background technology]
Sleeve pipe is the equipment for the protection of the borehole wall of geological drilling and engineering construction probing, and its range of application comprises: the fields such as engineering investigation, geological drilling, oil drilling, engineering drilling, hydrological well probing, Other Engineering construction drill.
Sleeve pipe is thin wall casing usually at present, and its structure is usually as follows: comprise a plurality of sleeve pipes, be respectively equipped with male thread, box thread on the both ends of each sleeve pipe, by male thread, box thread docking, each sleeve pipe is linked up.In this structure, on sleeve pipe both ends, the wall of thread connection part is thinner, and when the work progress middle sleeve needed the degree of depth under lower going-into-well large, thread connection part strength deficiency, sleeve pipe can't rise and reverse receipts, cause increase and the steel waste of drilling cost.
In order to solve the above problems, the practitioner has increased the wall thickness of sleeve pipe, but when finding to increase casing wall thickness, bore size during construction also must increase accordingly, so not only increase probing expense and tubing cost, annular gap between drilling tool post and sleeve pipe is increased, and the stressed complexity of drilling rod easily causes drilling accident; In addition, the increase of casing wall thickness has also increased simultaneously sleeve pipe and has worked the required power of dialling, the unrenewable risk of the sleeve pipe of increase of rising when dialling.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of sleeve structure of friction welding, makes the intensity at sleeve pipe both ends higher, and need not to increase the wall thickness of sleeve pipe, thereby has avoided because increasing the caused problem of casing wall thickness.
The utility model solves the problems of the technologies described above by the following technical programs: a kind of sleeve structure of friction welding, comprise a plurality of sleeve pipes, the both ends of every described sleeve pipe are friction welding one male joint, a female joint respectively, described male joint and female joint are mated mutually, and respectively this sleeve pipe coordinates connection by described male joint, female joint; 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 sleeve structure of a kind of friction welding of the utility model is: the both ends of sleeve pipe are friction welding one male joint, a female joint respectively, and this male joint is that carburizing male joint or nitriding male joint, female joint are the design of carburizing female joint or nitriding female joint, make the intensity on sleeve pipe both ends higher, the sleeve pipe of avoiding causing because of strength deficiency can't work the defective that reverses receipts, and because need not to increase the wall thickness of sleeve pipe, thereby avoided because of the caused series of problems of increase casing wall thickness, and then avoided the increase of drilling cost and the waste of steel.
[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 sleeve structure of a kind of friction welding of the utility model.
Fig. 2 is the exploded view of the sleeve structure of a kind of friction welding of the utility model.
[specific embodiment]
Please in conjunction with consulting Fig. 1 and Fig. 2, the sleeve structure of a kind of friction welding of the utility model, comprise a plurality of sleeve pipes, the present embodiment is set forth as an example of two sleeve pipes example, be respectively sleeve pipe 1, sleeve pipe 2, the both ends of sleeve pipe 1 are friction welding one male joint 3, a female joint 4 respectively, and also friction welding one this male joint 3 respectively, this female joint 4 of the both ends of sleeve pipe 2, described male joint 3 is mated mutually with female joint 4, and sleeve pipe 1 coordinates connection with sleeve pipe 2 by described male joint 3, 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.In addition, the external surface of male joint 3 is provided with the first screw thread 31, and the inner surface of described 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 sleeve pipe 1 and female joint 4 on sleeve pipe 2 are screwed to be connected (as shown in Figure 1) or the female joint 4 on sleeve pipe 1 and male joint 3 on sleeve pipe 2 are screwed to be connected (not shown), just can complete connecting of sleeve pipe 1 and sleeve pipe 2.
In the utility model, the both ends of sleeve pipe are friction welding one male joint, a female joint respectively, and this male joint is that carburizing male joint or nitriding male joint, female joint are the design of carburizing female joint or nitriding female joint, make the intensity on sleeve pipe both ends higher, the sleeve pipe of avoiding causing because of strength deficiency can't work the defective that reverses receipts, and because need not to increase the wall thickness of sleeve pipe, thereby avoided because of the caused series of problems of increase casing wall thickness, and then avoided the increase of drilling cost and the waste of steel.
Claims (2)
1. the sleeve structure of a friction welding, comprise a plurality of sleeve pipes, it is characterized in that: the both ends of every described sleeve pipe are friction welding one male joint, a female joint respectively, and described male joint and female joint are mated mutually, and respectively this sleeve pipe coordinates connection by described male joint, female joint; And described male joint is carburizing male joint or nitriding male joint, and described female joint is carburizing female joint or nitriding female joint.
