Problems solved by technology

[0002] The existing down-the-hole drilling rig only has the impact part (that is, the pneumatic down-the-hole impactor) submerged into the drill hole to drill the rock hole, and the compressed air is used as the power drive. The air compressor consumes a lot of energy and has low efficiency. The compressed air is delivered by the ground hollow drill pipe. and control impactor rotation

Embodiment approach

[0041] 1. It is better to use the combined punching and turning method for the integrated hydraulic down-the-hole drilling rig, that is, once the drill gets stuck (the drill bit is stuck and does not turn), the impact will stop, so as to avoid drilling due to the deep deformation of the local chisel marks at the bottom of the hole scrapped.

[0042] 2. In order to increase the torque without increasing the outer diameter, the blade can be lengthened longitudinally, or two to three gyrators can be connected in series, and the short shaft on the hub can be connected with a bushing.

[0043] 3. When the slewing mechanism is placed at the front of the impact mechanism, it can also be used in conjunction with the existing hydraulic rock drill impact mechanism, without gear transmission, and the structure is simple and compact.

[0044] 4. According to the patent principle of the present invention, a hydraulic down-the-hole hammer that only impacts can also be made to replace the ex...

Abstract

A hydraulic down-the-hole drill integrating impacting and rotating is composed of a concentric three-cavity tube, a flow divider, a swing mechanism, an impacting mechanism and a machine tail, wherein the shell end portions of the concentric three-cavity tube, the flow divider, the swing mechanism, the impacting mechanism and the machine tail are integrated. According to the hydraulic down-the-hole drilling machine integrating impacting and rotating, high pressure oil (or emulsified liquid) is transported by the three-cavity tube to serve as power drive so as to generate impacting and swinging, oil returning and powder discharging are boosted through compressed air, the overall drilling machine is submerged in a drilling hole, a drilling rod does not rotate, load is not increased because of lengthening of the drilling rod, and more ultra-deep drilling and underwater exploration drilling can be achieved. Because hydraulic pressure (10-20 MPa) is ten to twenty times higher than air pressure (1.2 MPa), through adopting the hydraulic pressure, ballistic work is high, torque is high, the drilling efficiency is high, and energy consumption is reduced by two thirds.

Description

technical field [0001] The invention relates to a down-the-hole drilling rig (rock drilling rig) driven by high-pressure oil (or emulsion) and driven by integrated punching and rotating. Background technique [0002] The existing down-the-hole drilling rig only has the impact part (that is, the pneumatic down-the-hole impactor) submerged into the drill hole to drill the rock hole, and the compressed air is used as the power drive. The air compressor consumes a lot of energy and has low efficiency. The compressed air is delivered by the ground hollow drill pipe. And control the impactor rotation. Contents of the invention [0003] Aiming at the deficiencies of the existing technology, it provides a down-the-hole drilling rig driven by hydraulic pressure, which is characterized by: large impact energy, high efficiency, energy consumption reduced by about two-thirds compared with pneumatic power, and the drill pipe does not rotate , will not increase the torsional load due t...
