A rod-taking mechanism for a core sampling drilling rig

Abstract

The invention provides a rod taking mechanism used for a rock core sampling drilling machine. The rod taking mechanism comprises a lifting mechanism, a grabbing main shaft posture changing mechanism and a mechanical arm grabbing mechanism, and the lifting mechanism is used for lifting or lowering a movable sliding block on a guide rail through assisting; the grabbing main shaft posture changing mechanism is used for assisting in changing of the operating angle of a corner connecting block and a grabbing main shaft; the mechanical arm grabbing mechanism is used for helping a tail end mechanicalarm to automatically and alternately grab two or more kinds of rod parts with different dimensions from a rod storage box. During application of the technical scheme, the rod taking mechanism is installed on the rock core sampling drilling machine through a drilling machine mast connecting pair, and is convenient to assemble; the rod taking mechanism can alternately and automatically grab the twoor more kinds of rod parts ( such as drill pipes and casings) with different dimensions, the rod parts in the rod storage box are automatically loaded at inclined or perpendicular power heads, or therod parts at the power heads are detached into the rod storage box. In this way, the labor intensity of workers is lowered, and construction efficiency and construction safety are improved greatly.

Description

technical field [0001] The invention relates to the technical field of geological engineering exploration equipment, in particular to a rod-taking mechanism for a core sampling drilling rig capable of realizing automatic sampling of at least two or more sizes of rods. Background technique [0002] With the rapid development of my country's economy, the research and development investment of my country's geological engineering exploration equipment has also maintained continuous growth. Core sampling rigs are important equipment in geological engineering exploration, and can be divided into two types: vertical shaft core sampling rigs and fully hydraulic core sampling rigs. However, these two types of drilling rigs need to manually install and disassemble the drill pipe during the drilling and coring process. As the drilling depth gradually increases, a lot of manpower and labor costs are required. [0003] In the process of inclined or vertical drilling and coring, the exis...

However, these two types of drilling rigs need to manually install and disassemble the drill pipe during the drilling and coring process. As the drilling depth gradually increases, a lot of manpower and labor costs are required.

[0003] In the process of inclined or vertical drilling and coring, the existing drilling rig cannot realize the alternate automatic grabbing of drill pipes or casings of two or more different sizes, and automatically add the rods in the horizontal rod storage box to the inclined or vertical At the mast of the power head, or the function of removing the rods at the mast of the power head into the rod storage box, the drilling efficiency is greatly reduced, and it does not meet the efficient and sustainable economic development model
