Abstract
The utility model belongs to a drill stem technology in the field of coal mines, and particularly relates to a spiral type triangular alloy drill stem which comprises a drill stem body. The front end of the drill stem body is provided with conical internal threads, and the rear end of the drill stem body is provided with conical external threads matched with the conical internal threads at the front end. Protruded spiral belts are arranged on the outer surface of the triangular alloy drill stem body and are fully distributed on the drill stem body. On the basis of an original triangular alloy drill stem, a spiral structure is added at the end or the whole of the original triangular alloy drill stem, and the threads are used for pushing out coal cinders backwards, so the occurrence rate of jamming of a drilling tool is reduced, the accidental loss of a drill bit of the drill stem is reduced, the coal cinder discharging capacity of the drill stem is enhanced, the overall performance of the drill stem is improved, and the service life of the drill stem is prolonged.
Description
Technical field
The utility model belongs to the Drill Pipe Technology in the field, colliery, is specifically related to a kind of screw type Rhizoma Sparganii alloy drilling rod.
Background technology
Under coal mine for preventing that gas accident from often adopting drilling rod drilling operation boring, its objective is detection of coal seam parameter and extraction coal-bed gas.Down-hole, in the construction drill process, is buried deeplyer due to coal seam, and the gas reset pressure increases, and the bit freezing phenomenon easily occurs while using the typical circular rod boring, and the present invention has overcome this defect of common drilling rod.
The utility model content
When there is the rod boring of prior art in the utility model for prior art, the smooth problem that bit freezing easily occurs of deslagging, propose a kind of screw type Rhizoma Sparganii alloy drilling rod.
The technical solution of the utility model is: a kind of screw type Rhizoma Sparganii alloy drilling rod, comprise drilling rod, the internal thread that the front end of drilling rod is taper, the another rear end of drilling rod is provided with the conical external screw thread with front end conical internal thread coupling, on the external surface of described Rhizoma Sparganii type drilling rod, is provided with protruding hurricane band.Hurricane band is covered with whole drilling rod.
Described screw type Rhizoma Sparganii alloy drilling rod, described hurricane band is two, and the hurricane band alternative ring is on the external surface of three drilling rods.
Described screw type Rhizoma Sparganii alloy drilling rod, described hurricane band is two, and the hurricane band alternative ring is around the front portion of three drilling rods.
The beneficial effects of the utility model are: the utility model is on the basis of original Three-edged drill stem, in termination or integral body add helical structure, utilize screw thread that cinder is released backward, thereby reduce the bit freezing incidence, reducing the accident of rod bit loses and loss, in the deslagging ability that has strengthened drilling rod, improved the combination property of drilling rod, extend the application life of drilling rod.
The accompanying drawing explanation
Fig. 1 is the cross section structure schematic diagram of existing Rhizoma Sparganii alloy drilling rod;
Fig. 2 is screw type Rhizoma Sparganii alloy jackrod structure schematic diagram of the present utility model;
In figure, 1 is conical internal thread, and 2 is conical external screw thread, and 3 is drilling rod, and 4 is double helix band steel band, and 5 is the tapered cup nut end.
The specific embodiment
Embodiment 1: in conjunction with Fig. 1-Fig. 2, a kind of screw type Rhizoma Sparganii alloy drilling rod, comprise drilling rod, the front end of drilling rod is the internal thread that taper is set, the another rear end of drilling rod is provided with the conical external screw thread with front end conical internal thread coupling, be provided with protruding hurricane band on the external surface of described Rhizoma Sparganii type drilling rod, hurricane band is two, and the hurricane band alternative ring is covered with whole drilling rod around hurricane band on the external surface of three drilling rods.
