Description

Technical Field

[0001] This utility model relates to the field of drill rod device technology, specifically a directional drill rod for a directional drilling machine. Background Technology

[0002] Directional drilling rigs are specialized equipment used for trenchless laying of underground pipelines, geological exploration, and other engineering projects. They achieve precise control of the drilling trajectory through a controllable guidance system, and have advantages such as high construction efficiency and low environmental impact. The directional drill rod is the core component of the directional drilling rig and is mainly used in trenchless construction, horizontal well drilling, and other scenarios. It needs to achieve precise trajectory control while transmitting torque and axial force.

[0003] Currently, drill pipes are connected by threads. The threads are the weakest link in the entire drill string. In the complex service environment, the joint between drill pipes is prone to fracture, resulting in low connection strength between drill pipes. Utility Model Content

[0006] Preferably, it further includes: a limiting sleeve, fixedly disposed at one end of the auxiliary sleeve; and a positioning groove, formed at the other end of the rod, wherein when the two rods are configured to be joined, the limiting sleeve is inserted into the positioning groove.

[0007] Preferably, it further includes: a sealing ring, fixedly disposed at one end of the connector; a sealing groove is formed inside the mating seat, and when the two rods are mated, the sealing ring is inserted into the sealing groove.

[0008] Preferably, it further includes: a first sealing ring, fixedly disposed inside the positioning groove; and a second sealing ring, fixedly disposed inside the sealing groove.

[0009] Preferably, it further includes: a limiting groove, formed on the outer surface of the rod body, wherein the positioning groove is connected to the inside of the limiting groove; a limiting through hole, formed through the outer surface of the limiting sleeve; and a limiting bolt, fixedly disposed inside the limiting groove, wherein the limiting bolt is located inside the limiting through hole.

[0010] This utility model provides a directional drill rod for a directional drilling rig, which has the following advantages:

[0011] This invention, through the design of the docking seat and auxiliary sleeve, ensures a tighter fit between the two rods after connection, improving the connection strength between the connecting rods. Furthermore, the tapered docking seat enhances the torsional strength at the junction of the two drill rod bodies, preventing breakage due to bending in complex underground environments. Additionally, the inclusion of a limiting sleeve, positioning groove, sealing groove, and sealing ring improves the sealing performance of the connection, preventing slurry from entering the joint and corroding or wearing the threads, thus extending the service life of the rods.
