深海底钻机自动接杆卸杆储管机构

Pipe Storage Mechanism of Automatic Rod Making up and Breaking out for Deep Seabed Rig

摘要:

本文介绍了一种深海底使用的钻杆钻具储管机构的工作原理和结构特点。按照深海底钻孔工艺，设计了自动接杆、卸杆、存储机构。这一种机构采用两个单排转笼式储管架，分别存放钻杆和钻具管组件。每一个储管架各配备一双机械手，用于夹持钻杆和钻具在孔口位和储管架管口位之间的移送和卡紧定位。该机构可靠性高，取心率高，结构简单，方便操作。

Abstract:

This paper introduces the working principle and structure characteristics of a pipe storage mechanism for drill rods and drilling tools used in deep seabed. According to the deep seabed drilling process, the automatic rod making up & breaking out and storage mechanism are designed. This kind of mechanism has 2 single-row rotary cage type pipe storage racks to store the drill pipe and drill pipe assembly respectively. Each pipe storage rack is equipped with a pair of manipulators to clamp the drill rod and drilling tools between the borehole mouth position and the outlet position of pipe storage rack for the transfer and tightening positioning. This mechanism has the advantages of high reliability, high coring rate, simple structure and convenient operation.
