摘要
针对液压支架铰接销拆卸难的问题,在普通锤式助拔器的基础上,利用风动扳手和螺旋副传动,研制了风动助拔器。降低劳动强度,提高生产效率,保证了安全,取得了较好的经济效益。
In view of taking down the hinge pin of hydraulic support , developed the pneumatic puller on the basis of usual hammer puller, pneumatic wrench and screw pair drive. It can reduce labor intensity, improve the production efficiency, undertake for security and get good economic benefit.
