大倾角工作面齿轨连接装置的改进设计

Design of Rack Rail Connection on Big Declivitous Workface

大倾角工作面中,安装和更换齿轨连接销的操作必须在链道区域进行,因为此处无防护网,煤矸飞落会造成人员伤害。设计改进了一种新型装置,可将操作工作置于防护网后,以保证工人的安全。

In a big declivitous workface,installation and replacement of rack rail connection has to work on scraper chain where has less protection.In this area,workers would be injured by falling coal.We design a new device.Workers can do all works after protective net to ensure workers safety.
