Abstract
A triangular drill pipe comprises at least two sections of pipe bodies with regular triangular sections. One end of each pipe body is provided with a guide connecting base, and the other end of the pipe body is provided with a guide connecting hole. The guide connecting bases and the guide connecting holes in any two sections of pipe bodies are matched. The side face, close to one end of each guide connecting hole, of each pipe body is provided with a mounting hole penetrating through the side wall, adapter holes are formed in the positions, corresponding to the mounting holes of the guide connecting holes, of the guide connecting bases, and fixed screws are arranged in the mouthing holes and the adapter holes in a penetrating mode. A plurality of grooves in parallel are formed in the side faces of the pipe bodies and are distributed in the side faces at equal intervals. An included angle of 30-50 degree is formed between each groove and each side face in the length direction. The triangular drill pipe is simple in structure, reasonable in design and low in cost. Through the arrangement of the guide connecting bases and the guide connecting holes, guiding and positioning effects can be achieved, then fixing pins are inserted in the guide connecting holes, and the installation is convenient and fast, and connection of multiple sections of pipe bodies can be achieved so as to adapt to ore deposits with different depths.
Description
Technical field
The utility model relates to a kind of mining drilling device, especially relates to a kind of triangle drilling rod.
Background technology
In engineering geology and mineral reserve probing, be widely used triangular drill rod, but what adopt due to the connected mode of tool joint place is that male and female is threaded, due to when mounted, owing to there is no positioner or locating in rundown process, cause like this location not good, often cause drilling rod to have certain alignment error, make the drilling rod after installing, occur that minute angle tilts, when drilling rod is worked, affect drilling life of drill pipe, and triangle drilling rod is used the ordinary multistage that sometimes needs to connect the ore bed that adapts to different depth.
Utility model content
The purpose of this utility model is the deficiency for solving the problems of the technologies described above, and a kind of triangle drilling rod is provided, and has solved for adapting to the repeatedly degree of depth ore bed problems such as location difficulty and installation trouble.
The utility model is the deficiency solving the problems of the technologies described above, and the technical scheme adopting is:
A kind of triangle drilling rod, comprise that at least two sections of cross sections are the body of rod of equilateral triangle, one end of the described body of rod is provided with guiding Connection Block, the other end offers guiding connecting hole, guiding Connection Block on any two sections of bodies of rod and guiding connecting hole match, on body of rod side near guiding connecting hole one end, offer the installing hole that connects sidewall, on guiding Connection Block, offer receiving hole with the installing hole corresponding position of guiding connecting hole, in installing hole and receiving hole, be equipped with hold-down screw, on described body of rod side, offer a plurality of grooves parallel to each other, each groove is equally spaced to be distributed on side, the length direction of groove and side is 30-50 ° of angle.
Described leg-of-mutton three angles are fillet, and three fillets are positioned on same circumference.
In the described body of rod, offer the Cooling Holes connecting along its length.
Described installing hole be in screwed hole or unthreaded hole any one.
Described receiving hole is screwed hole.
The Length Ratio installing hole of described hold-down screw and receiving hole length and little 1-3mm.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, cost is low, the utility model is provided with guiding Connection Block and guiding connecting hole, can play guide-localization effect, then insert steady pin, quick and easy for installation, multistage connects the ore bed that can adapt to different depth simultaneously.

The specific embodiment
Shown in figure, the specific embodiment is as follows:
A kind of triangle drilling rod, comprise that at least two sections of cross sections are the body of rod 3 of equilateral triangle, one end of the described body of rod 3 is provided with guiding Connection Block 2, the other end offers guiding connecting hole 6, guiding Connection Block 2 on any two sections of bodies of rod 3 and guiding connecting hole 6 match, on the body of rod 3 sides near guiding connecting hole 6 one end, offer the installing hole 5 that connects sidewall, on guiding Connection Block 2, offer receiving hole 1 with installing hole 5 corresponding positions of guiding connecting hole 6, in installing hole 5 and receiving hole 1, be equipped with hold-down screw 7, on the described body of rod 3 sides, offer a plurality of grooves parallel to each other 8, each groove 8 is equally spaced to be distributed on side, groove 8 is 30-50 ° of angle with the length direction of side, on the incline of the described body of rod, also have groove, groove 8 is communicated with and is formed, a continuous corral is around the thread groove of the body of rod.
Described leg-of-mutton three angles are fillet, and three fillets are positioned on same circumference.
In the described body of rod 3, offer the Cooling Holes 4 connecting along its length.
Described installing hole 5 be in screwed hole or unthreaded hole any one.
Described receiving hole 1 is screwed hole.
The Length Ratio installing hole 5 of described hold-down screw 7 and receiving hole 1 length and little 1-3mm.
The utility model in use, the guiding Connection Block 2 that passes through of two sections of bodies of rod 3 can be positioned to installation then by hold-down screw 7 insertion installing holes 5 and receiving hole 1 with guiding connecting hole 6, then tightening screw is fixed together two sections of bodies of rod 3, when triangle drilling rod is used, mineral aggregate can be discharged gradually by multistage groove 8, mineral aggregate directly interacts and makes it advance discharge, efficiently solves the problem of obstruction.
The technical scheme that the utility model is cited and embodiment are not restrictions, in the cited technical scheme of the utility model and embodiment is equal to or effect same approach is all protected at the utility model scope.
