Double-petal combined core barrel convenient for heat treatment

Abstract

The invention relates to a double-petal combined core barrel convenient for heat treatment, which comprises a mounting block and a base, wherein a first through hole is formed in the mounting block; afixing block is welded to the lower part of the mounting block; a second through hole is formed in the outer part of the fixing block; a first connecting block is welded to the lower portion of the fixing block; a first thread is arranged outside the first connecting block, a second thread is connected to the interior of the first thread, a second connecting block is arranged outside the second thread, a screw is installed on one side of the second connecting block, an explosive filling groove is arranged in the base, and the base is located on the other side of the second connecting block. The double-petal combined core barrel convenient for heat treatment has the beneficial effects that the double-petal combined core barrel convenient for heat treatment is made of metal, has the characteristic of high temperature resistance, is very high in metal melting point, does not deform or melt under common conditions, is convenient for heat treatment of a core barrel, is greatly convenient for people to use, and improves the practicability of the core barrel.

Description

technical field [0001] The invention relates to the technical field of core cylinders for automobile processing, in particular to a double-lobe combined core cylinder which is convenient for heat treatment. Background technique [0002] Core drilling is an exploration method often used in geological exploration of solid minerals. The cylindrical drill bit and drilling tool break the rock in a circular manner at the bottom of the hole, and a columnar core is reserved in the center of the hole bottom. In the case of minerals, it is called core drilling, and the core barrel is used for core drilling. [0003] In the Chinese invention patent CN89219808.7, a double-petal combined core barrel, the double-petal combined core barrel can be taken out to maintain the original shape of the core without cutting the inner core barrel, which is convenient and convenient. It is also economical. In addition, it can also solve the problem of difficulty in removing the barrel in the case of ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a double-lobe combined core barrel that is convenient for heat treatment, so as to solve the problems in the above-mentioned background technology, but it is not convenient for heat treatment, and it is not easy to take out the core barrel, so that the core barrel is stuck in the rock, and the core barrel The collected samples cannot be taken out for inspection, which is very inconvenient for people to use and cannot meet people's work needs
