旋挖钻机主卷扬机构的功能是提升或下放钻杆。主卷扬机构按其在整机上的位置可分为前置、中置和后置3种,按主卷扬机构的驱动形式可分为单减速器驱动和双减速器驱动2种。本文介绍主卷扬机构3种布置形式及2种驱动形式的构造及特点。1.主卷扬机构布置形式主卷扬机构安装在旋挖钻机桅杆或变幅机构上称为前置主卷扬机构;安装在回转平台的中部,即回转支承中心附近称为中置主卷扬机构;安装在回转平台的后部,即发动机之后、配重之前称
The main function of the rotary drilling rig main winch is to raise or lower the drill pipe. The main winch mechanism according to its position on the machine can be divided into front, middle and rear three, according to the main winch drive can be divided into single-reducer drive and dual reducer drive two. This paper introduces the structure and characteristics of three kinds of layout and two kinds of driving forms of the main hoist mechanism. 1. Main hoisting mechanism layout Main hoisting mechanism installed on the rotary drilling rig mast or luffing mechanism known as the front main hoisting mechanism; installed in the middle of the rotary platform, that is, near the center of the slewing ring called the main winch lifting mechanism; installation In the back of the rotary platform, after the engine, before weighing said
