Problems solved by technology

[0004] In traditional operations, the entire device must be lifted out of the hole. When the drilling depth reaches hundreds or even thousands of meters, the repetitive labor and auxiliary work time for extracting the drill pipe will account for a large proportion, and even account for 70% in deep hole operations. left and right, greatly reducing production efficiency

Abstract

The invention relates to a reclaimable drilling rig device which mainly comprises an elastic clamp stop head, an elastic clamp chamber, a hole expanding opener and an outer pipe that are connected through threads to form an integral outer pipe; a recycling pipe in the outer pipe is connected with an elastic clamp frame and an elastic clamp seat through a second elastic cylindrical pin; a first spring sleeve is sleeved in a positioning pressure block which is positioned in a spear dragging head through a spear dragging seat; two elastic clamp clippers are mounted in pairs and positioned in therecycling pipe through a first elastic cylindrical pin; the elastic clamp frame is connected with a first joint through threads; the first joint seat is arranged on a suspending ring and is arranged on a seat ring; a third joint is connected with a second joint through threads, the second joint is connected with a joint through threads; and a shaft penetrates into the third joint, and an inner pipe is connected to a fourth joint through threads. When a rock core is extracted, the inner pipe is dragged out without dragging out the drilling jig, which is safe and reliable; the material processing difficulty is low, and the cost is controllable; and the working efficiency is greatly improved and the construction cost is reduced.

Description

technical field [0001] The present invention relates to a retrievable drilling tool device, in particular to a device for quickly extracting rock cores in drilling rigs in the drilling industry. The inner tube filled with rock cores is quickly lifted out through a snap-in device. It belongs to the field of engineering machinery (drilling rig). Background technique [0002] With the promulgation of the State Council's strategic decision on deep ore prospecting and crisis mine replacement resource investigation, the industry development trend of deep ore prospecting in the drilling industry will become more prominent. Efficiency will become an important bottleneck restricting the development of the industry. How to ensure the construction quality and efficiency of deep drilling will be a key issue for drilling equipment manufacturers to solve. [0003] In order to improve the construction efficiency during the drilling construction process, it is necessary to increase the pur...
