Automatic storage system for drill stem

Abstract

The invention relates to an automatic storage system for a drill stem. The automatic storage system comprises drill stem storerooms, a grab mechanism and a driving mechanism, wherein the drill stem storerooms are two and are mainly used for storing various drill stems, and each drill stem storeroom can store 60 drill stems; the driving mechanism is mainly used for driving the drill stems in the drill stem storerooms to rotate intermittently to ensure that the drill stems in the drill stem storerooms can rotate a certain angle each time; the grab mechanism is used for storing the drill stems and realizing the assembly and disassembly of the drill stems, so that a drilling tool moves among three positions, namely the left drill stem storeroom, the right drill stem storeroom and a power head; and actions such as the storage, take-off, clamping, assembly and disassembly and the like of the drill stems can be completed accurately by the matching among the drill stem storerooms, the grab mechanism and the driving mechanism. The storage system has a simple structure, is large in capacity, convenient to operate and high maintainability, and offers a reliable performance; and when the storage system is used, unmanned operation is realized, the work efficiency is high, and the automatic storage or remote control of the drill stems can be realized in special severe work environment.

Description

technical field [0001] The invention relates to an automatic access system for drill pipes, which is suitable for automatic access to drill pipes when drilling in harsh environments such as mines, mountain slopes, and seabeds. Background technique [0002] At present, most domestic drilling rigs are not equipped with a drill pipe storage and retrieval system that can realize automatic storage and retrieval of drilling tools. The storage and retrieval of drilling tools largely depends on manpower, which is labor-intensive, inefficient, and time-consuming. Especially in some special working environments, such as drilling in harsh environments such as mines, mountain slopes, and seabeds, a system that can automatically access drill pipes is needed to realize drilling automation and remote control. At present, a small number of land drilling rigs have established drill pipe warehouses, equipped with drill pipe automatic storage and retrieval systems, but the drill pipe automatic...

AI Technical Summary

Problems solved by technology

[0003]1. Some automatic drill pipe storage systems are only used for shallow hole drilling, and the system can accommodate a small amount of drilling tools

[0004]2. Some automatic drill pipe storage and retrieval systems have complex structures and are used on drilling platforms, but not suitable for seabed exploration equipment

[0005]3. Some automatic drill pipe storage and retrieval systems have many working stations in the grabbing mechanism, which is difficult to control and low in precision
