Drilling machine-free self-balancing rotary vibration coupling rock crushing drilling system

Abstract

A drilling-machine-free self-balancing rotation vibration coupling rock crushing drilling system comprises an inner drill bit driving system, an outer drill bit driving system, a bit pressure distribution system and the like, an inner drill bit and an outer drill bit are driven by two motors to achieve self-balancing single rotation and self-balancing double rotation of the inner drill bit and the outer drill bit respectively, and the problem of control over self-balancing torque is solved; the drilling efficiency of the drilling system is improved by assisting double drill bits in rotary rock crushing through ultrasonic vibration, the risk that a back reaming grinding head is stuck is reduced by amplifying the output torque of a motor by multiple times through a reduction gear mechanism, and the problem that the transmission efficiency of strong current and weak current is low is solved by canceling a conductive slip ring. The back reaming drill bit has the following advantages that the vibration and rotation drilling efficiency is high, the inner drill bit and the outer drill bit rotate at the same time, self-balancing control is easy, the back reaming grinding head is not prone to being stuck due to large rotation torsion, the transmission efficiency of strong and weak electricity in a drilling system is high and stable, and the drilling reliability and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of drilling and drilling technology, and in particular relates to a rig-less self-balancing rotary vibration drilling suitable for technical fields such as geological drilling, hydrological water well drilling, oil and gas drilling, scientific drilling, extraterrestrial bodies and underground construction rescue drilling. system. Background technique [0002] In the development process of the existing drilling (drilling) technology, almost all technological improvements and innovations are based on the structure of the existing drilling rig, drill pipe and drilling tool, no matter how the improvement can not change the energy transmission of the drilling rig to the drill bit The problem of high process consumption and low drilling efficiency is rooted in the fact that the counter torque generated by the drill bit is driven and balanced by the "long arm jurisdiction" style through the ground drilling rig.

Problems solved by technology

[0005] The purpose of the present invention is to address the deficiencies described in the background technology, to provide a self-balancing rotary vibration coupling rock crushing drilling system without drilling rigs, and to improve the drilling efficiency of the drilling system through vibration-assisted double drill bit rotary rock crushing; Drive the inner drill bit and the outer drill bit to realize the self-balancing single-rotation and self-balancing double-rotation of the inner and outer drill bits, which solves the problem of self-balancing torque control; through the reduction gear mechanism, the output torque of the motor is amplified multiple times, reducing the chance of unblocking the bit being stuck Risk; input electric energy through high voltage on the ground, and the transformer installed in the drilling tool supplies power to the actuator, which reduces the big problem of long-distance power supply voltage consumption; solves the problem of low transmission efficiency of strong and weak currents by canceling conductive slip rings
