Abstract
The utility model provides a hexagonal drill rod. The hexagonal drill rod comprises a rod body, and a male connector and a female connector which are fixed at the two ends of the rod body, wherein an internal thread and an external thread are arranged on the male connector and the female connector respectively; the section of the rod body is hexagonal; the internal thread and the external thread are tapered threads; an O-shaped sealing ring is arranged on the male connector. The hexagonal drill rod is simple in structure; through hexagonal arrangement, hole collapse, drill blockage and drill loose can be effectively reduced; the male connector and the female connector are connected through trapezoidal tapered threads, so that detachment and connection of the connectors are relatively convenient; through arrangement of the sealing ring on the male connector, water or gas does not leak while passing through the connectors, so that the sealing performance is improved.
Description
Technical field
The utility model relates to a kind of Three-edged drill stem, belongs to technical field of mining equipment.
Background technology
In process of coal mining, to coal and Coal Seam Prone To Outburst, need to before mining, to the gas in coal seam, carry out extraction, gas in the extraction coal seam extraction borehole of need to constructing in coal seam, what use was maximum at present is mainly Three-edged drill stem, common Three-edged drill stem pin and box sub mainly adopts regular screw threads to connect, and makes dismounting and is connected all conveniently not, and joint is without encapsulation process in addition, make easily to leak when flowing through joint at water or gas, can not meet industrial production demand.
Summary of the invention
For above-mentioned weak point of the prior art, the utility model provides a kind of dismounting, easy to connect, six rib drilling rods of joint good sealing effect.
To achieve these goals, the utility model provides following technical scheme: a kind of six rib drilling rods, comprise the body of rod and be fixed on male joint and the female joint at body of rod two ends, in described male joint and female joint, be provided with internal and external screw thread, described body of rod cross section is regular hexagon, described internal and external screw thread is taper thread, is provided with O RunddichtringO in described male joint.
As preferably, described taper thread is trapezoidal taper thread made in Great Britain.
By above technical scheme, can find out, the utility model is simple in structure, arranging of six ribs can effectively reduce collapse hole, bit freezing and lose brill phenomenon, male and female joint adopt trapezoidal tapering made in Great Britain to be threaded to make its dismounting be connected convenient, in male joint sealing ring be arranged so that when water or gas, can not leak during through joint, improve sealing.
