Description

Technical Field

[0001] The utility model relates to the field of raise well drilling machines, in particular to a drill rod structure of a raise well drilling machine. Background Art

[0002] The raise drilling rig uses the drilling rig's motor to drive the hydraulic motor, which drives the faucet and uses hydraulic power to transmit torque to the drilling tool system, driving the drill rod and drill bit to rotate. The roller cutter on the guide hole drill bit or the reaming drill bit rolls or slides slightly along the rock working surface at the bottom of the well under the action of drilling pressure. At the same time, the axial tension and pressure generated by the main engine cylinder also act on the guide hole drill bit or the reaming drill bit through the power head and the drill rod, causing the roller cutter of the guide hole drill bit to roll under the action of drilling pressure, generating impact loads, causing the roller cutter teeth to impact, squeeze and shear the rock, breaking the rock. When the drilling rig is drilling, the drill rod is needed, so a drill rod structure for the raise drilling rig is needed.

[0003] The existing patent document with the technical disclosure number CN213450273U provides a drill rod for a raise boring machine, which relates to the technical field of drill rod connection of the raise boring machine. It includes a rod body and an external thread arranged at one end of the rod body. The other end of the rod body is provided with an internal thread. Both the external thread and the internal thread are oblique trapezoidal tapered threads. The tooth width of the oblique trapezoidal tapered thread is L1, the tooth pitch is P, the tooth height is H1, the distance from the circumference of the middle diameter to the tooth bottom is H2, the tooth bottom of the oblique trapezoidal tapered thread and the center line of the thread have an angle c, one side of the tooth of the oblique trapezoidal tapered thread and the perpendicular line of the thread center line have an angle a, and the other side of the tooth of the oblique trapezoidal tapered thread and the perpendicular line of the thread center line have an angle c. The beneficial effects of the utility model are as follows: the inclined trapezoidal tapered thread connection structure adopted by the raise boring machine drill rod of the utility model has a bearing capacity of bending stress, shear stress and extrusion stress that exceeds that of the triangular thread adopted by the current raise boring machine drill rod, and reduces the risk of thread root fracture. However, the CN213450273U technology is not convenient for connection anti-loosening and connection fast positioning of the device during operation, and the device parts rotate for a long time, which is not convenient for parts to be protected from wear. Therefore, a raise boring machine drill rod structure is urgently needed. Utility Model Content
