Problems solved by technology

[0003] Although the single-tube pumpless drilling tool can increase the core recovery rate in extremely broken and weak formations, the construction efficiency is low and the labor intensity is high due to the need to lift the drill core, and frequent lifting of the drill affects the stability of the hole wall

Abstract

The invention discloses a hydraulic rock core lifting device for exploratory boring. The device comprises a waterproof transfer mechanism, a diversion limiting mechanism, a pressure storage mechanism, an elevation injection molding mechanism, a hydraulic core clamping mechanism, a lateral jet drill bit transfer mechanism and a sealing system, wherein the diversion limiting mechanism is butted with the waterproof transfer mechanism; the pressure storage mechanism is butted with the diversion limiting mechanism; the elevation injection molding mechanism is butted with the pressure storage mechanism; the hydraulic core clamping mechanism is butted with the elevation injection molding mechanism; the lateral jet drill bit transfer mechanism is butted with the hydraulic core clamping mechanism. The device can be directly matched with a double-tube drilling tool and a rope core drill to achieve a coring rate of 100 percent for a complicated difficult-to-core formation such as a soft and loose formation and a broken formation; in addition, a rock core can be fully automatically lifted, bundled and controlled under three-dimensional stress on the basis of hydraulic pressure; moreover, a conventional core clamping and cutting device is matched to achieve the characteristics of high reliability, high coring efficiency, high coring quality, high rock core collection rate, wide applicable formation range, high automation performance and the like.

Description

technical field [0001] The invention relates to a rock (mine) core picking device for drilling and coring, in particular to a rock (mine) core picking device suitable for drilling and coring in soft, loose and extremely broken formations. Background technique [0002] Drilling technology is currently the only exploration technology method that can take out solid rock and mineral samples from the ground. , environmental scientific drilling, etc., showing the irreplaceable important role of drilling technology. However, the current drilling environment has moved from the shallow surface that is easy to excavate to the deep, and the situation will be that resources are difficult to find, difficult to excavate, higher altitudes, and land shifting to lakes and oceans, which poses higher requirements for drilling efficiency and quality. requirements. The acquisition of true and reliable geological data relies on the ability of drilling technology to cope with different environme...
