Embodiment 2

[0034] During the drilling operation, the broken cuttings are washed by the flushing fluid when the pilot hole is drilled, and the cuttings are lifted out of the borehole by the flushing fluid along the annular space between the drill pipe and the hole wall. The friction between the flushing fluid and the drill pipe can easily lead to poor slag discharge, and easily cause disturbance to the drill pipe, affecting the accuracy of drilling.

[0035] In order to solve the above problems, this embodiment provides a raise drilling machine, including the drill pipe conveying device provided in Embodiment 1, and also includes a friction-reducing drill pipe, refer to Figure 5 , the friction-reducing drill pipe includes: a rod body 110 , the inside of the rod body 110 is provided with a well-washing fluid flow path 111 arranged axially along the rod body 110 , and the outer surface of the rod body 110 is provided with a drag-reducing structure.

[0036] When working, the flushing fluid...

Embodiment 3

[0049] refer to Figure 9 , On the basis of Embodiment 2, the friction-reducing drill pipe in this embodiment further includes a stabilizing ring 130 , the stabilizing ring 130 is sleeved on the rod body 110 , and the outer diameter of the stabilizing ring 130 is larger than the outer diameter of the rod body 110 .

[0050] When the flushing fluid flows through the stabilizing ring 130 from bottom to top, the circumferential turbulent flow in the stabilizing ring 130 forms a liquid gasket. When the friction-reducing drill pipe deviates, the turbulent flow on the compressed side of the liquid gasket is close to the hole wall, and the liquid pressure Increase to align the reduced-friction drill pipe.

[0051] Specifically, the lower surface of the stabilizing ring 130 and the connecting portion of the rod body 110 have an excessively circular arc. The resistance of the stabilizing ring 130 to the flushing fluid is reduced through the arc transition.

[0052] More specifically,...

Embodiment 4

[0054] In this embodiment, the friction-reducing drill pipe of the raise drilling rig, on the basis of Embodiment 2, also includes a water flow direction sensor arranged on the surface of the rod body, and the water flow direction sensor sends the water flow direction signal to the controller, and the controller drives the The device adjusts the rotation angle of the turntable 120 so that the direction from the big end to the tip of the groove 121 is consistent with the direction of water flow. The flow direction of the water flow is sensed by the water flow direction sensor, so that the angle of the turntable 120 is automatically adjusted by the controller, which can automatically adapt to different working conditions.

[0055] More specifically, the rod body 110 is divided into multiple sections from top to bottom, each section is provided with a water flow direction sensor, and the controller independently controls the direction of the turntable 120 in the corresponding sect...

Abstract

The invention relates to the technical field of raise boring machines, and discloses a drill rod conveying device and a raise boring machine. The drill rod conveying device comprises a base, one side of the base is provided with a placing groove, the inner wall of the placing groove is fixedly connected with a first hydraulic cylinder, the output end of the first hydraulic cylinder is movably connected with a first hydraulic rod, and one side of the first hydraulic cylinder is fixedly connected with a spring. According to the drill rod conveying device, the purpose that the conveying effect of the conveying device is good is achieved, so that the problem that a common drill rod conveying device is poor in conveying effect is solved, the conveying device can effectively convey a drill rod to a connector of the raise boring machine in the using process, the process is rapid and convenient, butt joint of the drill rod and the raise boring machine is more rapid and accurate, the butt joint time is reduced, so that the use cost of people is reduced, the working efficiency of people is also improved, people are more worry-saving in use, the use requirements of people are met, and convenience is brought to the work of people.

Description

technical field [0001] The invention relates to the technical field of raise drilling rigs, in particular to a drill pipe conveying device and a raise drilling rig. Background technique [0002] The raise drilling rig drives the hydraulic motor through the motor of the drilling rig, the hydraulic motor drives the faucet, and uses the hydraulic power to transmit the torque to the drilling tool system, driving the drill pipe and the drill bit to rotate, and the hob on the pilot hole drill bit or the reaming bit is under drilling pressure. Under the action of the rock working face at the bottom of the well, it will do pure rolling or slight sliding. As we all know, the drill pipe is one of the parts of the raise drilling machine. When people install the drill pipe, they need to use the conveying device. [0003] However, the delivery effect of the existing drill pipe conveying device is not good, so that the conveying device cannot effectively connect the drill pipe and the dr...
