The central cable-through drill rod is also called as a measurement-while-drilling drill rod and is mainly applied to a kilometer directional drilling machine for directional drilling of deep holes.

The directional drilling technology is one of the most advanced drilling methods in the world at present, and is a drilling method which utilizes the natural bending rule of a drill hole or adopts an artificial deflecting tool to enable the drill hole to extend to a preset target according to the design requirement, and can drill to a specified position according to a pre-designed drilling track.

The central cable drill rod is a signal transmission device used for directional drilling and is an important component for ensuring the smooth implementation of the directional drilling. Due to the fact that the drill rod is used in a severe environment, higher requirements are placed on the quality of signal transmission and the performance stability of the rod body.

Central through-cable drill pipes are generally required to be constructed in complete coal seams f > 1 or stable rock formations f < 6; the method is mainly used for the underground near-horizontal long-distance gas drainage drilling and water exploration and drainage drilling construction of the coal mine, and can also be used for directional drilling construction such as the drilling of ground and underground tunnel near-horizontal engineering and the like. The method is mainly applied to underground directional drilling of coal mines, underground rotary drilling of coal mines, other geological controlled directional drilling working conditions, gas drainage, development of gas layers, emergency rescue, detection and discharge of accumulated water in goafs, geological structures and the like.

Because the drill rod with the central through cable is generally longer in size, and meanwhile, the torque and the shaking generated in the drilling process of the drill rod are also considered, the installation reliability and the use guarantee of the through cable in the drill rod have higher requirements, otherwise, the stability of signal transmission cannot be guaranteed.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, such as "connected," which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The central cable-passing drill rod comprises a drill rod 1; one end of the drill rod 1 is provided with an external thread joint 2, and the other end is provided with an internal thread joint 3; two ends of the drill rod 1 are symmetrically provided with annular platforms 5; a through cable 4 is arranged in the drill rod 1 and is supported by a ring platform 5; a clamping ring 7 is arranged on the outer end cable 4 of the ring platform 5; the clamping ring 7 is in threaded connection with the through cable 4 through a mounting thread 6 in the clamping ring; one end of the through cable 4 is provided with a groove 9, and the other end of the through cable is provided with a boss 11; a contact 10 is arranged in the groove 9; a spring joint 12 is arranged in the boss 11.

The male adapter 2 and the female adapter 3 are matched. The ring platform 5 is connected with or welded with the inner end of the drill rod 1 through threads. The groove 9 is matched with the boss 11, and the spring joint 12 is in a tower-shaped structure shape.

The device is also provided with a mounting and fastening device; a plurality of through holes 8 with equal distance are arranged on the annular table 5 in a surrounding way; the mounting and fastening device comprises a rotary disc 13; one end of the rotary disc 13 is provided with a rotating shaft 15; a rotating handle 17 is arranged on the rotating shaft 15; the other end of the rotary table 13 is provided with a clamping strip 14 matched with the through hole 8; the length of the clamping strip 14 is greater than the distance from the inner end of the through hole 8 to the outer end of the drill rod 1. A plurality of reinforcing rings 16 are arranged on the clamping strip 14; the outer diameter of the reinforcing ring 16 is smaller than the inner diameter of the drill rod 1, and the inner diameter of the reinforcing ring 16 is larger than the outer diameter of the through cable 4. The number of the clamping strips 14 is 3-8. The clamping rings 7 on two sides can be smoothly installed and used by ensuring one installation and fastening device. Meanwhile, the reinforcing ring 16 reinforces the rigid structure of the clamping strip 14, and ensures the use effect.

And a rubber gasket is arranged between the ring platform 5 and the snap ring 7.

And threaded blades are arranged on the periphery of the drill rod 1.

The working principle is as follows:

the ring platforms 5 can be fixed inside the drill rod 1 by threads or welding, and if the drill rod 1 is longer, the number of the corresponding ring platforms 5 can be increased continuously in the drill rod 1 so as to ensure the supporting and righting effects.

Preferably, the ring platforms 5 at two ends of the drill rod 1 are symmetrically arranged, namely, the distance from the ring platform 5 at the left end to the outer edge of the left end of the drill rod 1 is equal to the distance from the ring platform 5 at the right end to the outer edge of the right end of the drill rod 1.

The through cable 4 is inserted into the annular table 5, and the outer diameter of the through cable 4 is consistent with the inner diameter opening of the annular table 5 in size.

And then the clamping ring 7 is screwed up to realize the thread fixed connection. It should be noted that the through cable 4 is in threaded connection with the snap ring 7, wherein the through cable 4 is in an inner groove threaded structure, and the snap ring 7 is internally provided with a convex mounting thread 6. Through the inner groove thread structure of the through cable 4, the through cable 4 can be smoothly inserted into the annular table 5 and is locked and fixed through the clamping ring 7.

The installation and fixation are inconvenient because the clearance between the through cable 4 and the drill rod 1 is small during the actual operation. Thus, by designing the mounting fastening means, a threaded mounting of the snap ring 7 is ensured.

The clamping strips 14 are inserted into the corresponding through holes 8, and then the rotary handle 17 is rotated integrally to realize the rotation of the clamping ring 7 so as to achieve the effect of threaded installation and fastening.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
