Abstract
The utility model relates to a triangular drill rod, which comprises a male joint, a drill rod body and a female joint, and is characterized in that: bosses at the ends of the male joint and the female joint are inserted into the drill rod body and welded at the two ends of the drill rod body; and four clamping grooves are formed on the female joint. The triangular drill rod is convenient to process, has light weight, has high direction control property during drilling, is difficult to hold and clamp, is clamped by four planes when twisted and disassembled, is safe and reliable, does not slip, and is favorable for reducing cost and improving work efficiency during construction.
Description
Technical field
The utility model relates to the mining drilling rod of a kind of drilling well.
Background technology
Existing drilling rod mostly is triangle integral type drilling rod, i.e. male joint, female joint and drilling rod body three parts are integral type, and such shortcoming is that processing is difficult for cost height, and the complex structure of the hydraulic chuck clamper of unloading drilling rod, price height.
The utility model content
The purpose of this utility model is to provide a kind of split type triangle drilling rod.
To achieve these goals, by the following technical solutions: a kind of triangle drilling rod, comprise male joint, drilling rod body and female joint is characterized in that: shown in the boss of male joint and female joint end insert in the drilling rod body, be welded on the two ends of drilling rod body.
As further optimization, clamping for convenience, described female joint is provided with four draw-in grooves.
The triangle drilling rod of the utility model band screens, easy to process, firm welding, whole axiality is good, in construction, be difficult for to embrace bore, bit freezing, four draw-in grooves during the unloading drilling rod, safety, reliable, cost is low, be of value to reducing construction cost, increasing work efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A-A sectional view among Fig. 1;
Fig. 3 is the sectional view of B-B among Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As shown in Figure 1 to Figure 3, a kind of triangle drilling rod with screens, it is made up of male joint 1, drilling rod body 2 and female joint 3.The inside and outside wall of described drilling rod body 2 is the prismatic of circular arc type, and the boss of described male joint 1 and female joint 3 inserts the two ends and the welding of drilling rod body 2 endoporus respectively and reinforces, and is provided with four square draw-in grooves 4 at distance boss certain distance.During use, be stuck on the draw-in groove 4, the male joint of another drilling rod is mounted in the female joint, get final product coupling together successively by special tool.
The utility model is easy to process, in light weight, and the boring time control is good to performance, is difficult for embracing brill, bit freezing, and four plane screens are safe, reliable, non-slip during the unloading drilling rod.In construction, be of value to and reduce cost, increase work efficiency.
