ZM70型支架回撤牵引机的研制

Design on ZM70 Support Retrieving Dragger

支架回撤牵引机是基于井下综采工作面支架的长距离搬运而研制的一种具有举升、回转、伸缩及自行走功能的无轨运输装备,详细介绍了该机的主要结构组成、工作原理,可实现支架回撤过程中拆卸的机械化作业,提高液压支架回撤效率与安全性。

The ZM70 support retrieving dragger is a kind of trackless haulage equipment which has the function of lifting,rotating ,telescopic,driving.The equipment is based on the support transportation long-distance in the fully-mechanized face of the coal. Its main structure and operation principle are introduced. It realizes disassemble mechanized working when the support is retrieving. The efficiency and safety are improved on the progress of support withdrawing.
