旋挖钻进用牙轮筒钻的结构探讨及应用
|
摘要
牙轮筒钻是旋挖钻进入岩的一种常用钻具,为解决入岩钻进难、效率低的问题,通过牙轮筒钻运动方式和破岩机理的分析,提出了牙轮筒钻在结构设计时重点应考虑牙轮的布置、角度及硬质合金齿的选择等问题,可更换牙轮的锁紧方式及扩孔筒钻的结构特点,给出了适合于旋挖钻进入岩的牙轮筒钻结构,并通过生产试验,取得了很好的使用效果。
The core barrel with roller bits is a common drilling tool for rotary drilling into rock. In order to solve the problem of difficulty and low efficiency in rock drilling, this paper analyzes the movement mode and rock breaking mechanism of the core barrel with roller bits. In the structural design of the core barrel with roller bits, the focus should be put on the arrangement and placement angle of the roller bits, and the selection of the carbide teeth, as well as the locking method of the replaceable rollers and the structural characteristics of the reaming core barrel. This paper presents the structure of core barrel with roller bits suitable for rotary drilling which has achieved good results in the production test.
