反循环冲击钻同步卷扬的设计

Design of Synchronous Hoist in Percussive Reverse Circulation Dill

分析比较了冲击反循环钻机同步卷扬采用圆锥齿轮差速同步机构和圆柱齿轮差速同步机构的工作原理和特点。采用这种差动轮系成功地解决了重锤提升双绳同步问题，使冲击反循环钻进技术在我国桩墙施工中获得广泛推广应用。

The paper analyzes and compares the principle and characteristics of the bevel gear, and the spur gear differential trains, which are applied to the design of synchronous hoist in percussive reverse circulation drill respectively. Because of the simple structure and operating reliability of the synchronous hoist, the technology of percussive reverse circulation drilling is widely used in pilling and diaphragm wall.
