Abstract
The utility model discloses a kind of abrasion-proof drill rod, comprise drilling rod body, its one end is provided with male connection, the other end is provided with female adapter, and male connection and female adapter match, described drilling rod body surface circumferentially arranges circular wear-resisting projection, and the diameter of wear-resisting projection is greater than drilling rod body, male connection and female adapter, is provided with spiral ridge in wear-resisting convex surfaces.The utility model structure is simple, and reasonable in design, anti-wear performance is good, long service life.
Description
Technical field
The utility model belongs to drilling tool technical field, particularly relates to a kind of drilling rod.
Background technology
Drilling rod connects drill bit in drilling tool, in order to transmit the rod member of power, is mainly used in the fields such as hydrogeologic prospecting, well and oil drilling.Operationally, drilling rod can enter in boring with drill bit, and drilling rod and hole wall contact friction, be easy to be worn, and causes application life too short.
Therefore, the direction becoming these those skilled in the art and make great efforts how is solved the problems of the technologies described above.
Utility model content
The purpose of this utility model is just to provide a kind of abrasion-proof drill rod, can solve above-mentioned the deficiencies in the prior art part completely.
The purpose of this utility model is realized by following technical proposals:
A kind of abrasion-proof drill rod, comprise drilling rod body, its one end is provided with male connection, the other end is provided with female adapter, and male connection and female adapter match, it is characterized in that: described drilling rod body surface circumferentially arranges circular wear-resisting projection, the diameter of wear-resisting projection is greater than drilling rod body, male connection and female adapter, is provided with spiral ridge in wear-resisting convex surfaces.
As preferably, described drilling rod body surface is provided with wearing layer, and wearing layer surface is matsurface.
As preferably, described spiral ridge Dispersion on surface is inlaid with alloy cutting edge.
Compared with prior art, the beneficial effects of the utility model are: structure is simple, and reasonable in design, anti-wear performance is good, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
As shown in Figure 1, a kind of abrasion-proof drill rod, comprise drilling rod body 1, its one end is provided with male connection 2, the other end is provided with female adapter 3, and male connection 2 and female adapter 3 match, and described drilling rod body 1 surface circumferentially arranges circular wear-resisting protruding 4, the wear-resisting diameter of protruding 4 is greater than drilling rod body 1, male connection 2 and female adapter 3, is provided with spiral ridge 5 on wear-resisting protruding 4 surfaces.
Described drilling rod body 1 surface is provided with wearing layer 6, and wearing layer 6 surface is matsurface.
Described spiral ridge 5 Dispersion on surface is inlaid with alloy cutting edge 7.
In use, wear-resisting protruding 4 contact with hole wall, can avoid drilling rod body 1 directly and hole wall contact friction, spiral salient 4 can play the effect of chip removal simultaneously, and improve drilling efficiency, the phenomenon of effective minimizing collapse hole, bit freezing occurs, and alloy cutting edge 7 can strengthen cutting power further, extends drilling life of drill pipe.Drilling rod body 1 surface is also provided with wearing layer 6 in addition, protects drilling rod further, increases the service life.Wearing layer 6 surface is convenient to Work tool for matsurface and is clamped it.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
