Three-in-one combined core drilling outfits

Abstract

The invention relates to a kind of trinity sectional core drill. It incldues rope salvaging tool, outer tube assemblage, inside tube assemblage, screw rod motor, hydrodynamic drowning hole hammer, drill core carrying pipe, drillnig bit, position-setting device that is used to fix inside tube assemblage and eliminate the anti-torsion produced by the stator of the screw rod motor, torsion-transmitting gear and III that is used to transmit the tosional from the screw rod motor to the outer tube assemblage and drilling bit, dividing gear of flushing liquor that is used to divide the flushing liquor before it enter into hydrodynamic drowning hole hammer, movnig-only gear of outer tube that make the underpart drilling tool of outer tube assemblage rotate back, transmitting gear of impact energy that is used to transmit the impact energy from the hydrodynamic drowning hole hammer to theo uter tube, and the trimmer gear VII that is used to adjust the crooked degree of inside tube assemblage. This invention combines the rope core-fetching gear, bottom well power and garrulous rock hydrodynamic drowning hole hammer organically into a whole, thus can get the core without carrying the drill, improve the drilling efficiency in certain time greatly, reduce the times of removing the bit, and increase the pure drilling time.

Description

technical field [0001] The invention relates to a three-in-one combined core drilling tool for solid mineral exploration. Background technique [0002] In the exploration of solid minerals, most of the core drilling tools with a single technology are used, and the conventional wireline core drilling tools are used. Due to the thick lip of the drill bit, the efficiency is low and the frictional resistance between the drill string and the well wall is large, so it is difficult to achieve high speed. The use of the screw motor drilling tool requires the entire drill string to be lifted to the ground to obtain the core, which has the disadvantages of long lifting time and many lifting times. The hydraulic down-the-hole hammer drilling tool can improve the drilling efficiency per unit time, but it also has the disadvantages of many lifting times and long auxiliary time. Contents of the invention [0003] The object of the present invention is to provide a high-efficiency three...
