竖井抓岩机

竖井抓岩机介绍

竖井抓岩机,由钢绳悬吊分瓣抓斗抓取爆破的岩石并装人专用吊桶内的竖井掘进机械。竖井抓岩机按斗容分为小型(0.2m)、中型(0.250.65m)和大型(≥0.7m);按动力分为气动、电动和液压三类;按操纵方式分为手动和机械两种;按结构型式和安装方式分为靠壁式、轨道式和中心回转式

竖井抓岩机工作原理

由地面凿井绞车单独悬吊靠井壁布置的竖井抓岩机,由抓斗、提升机构、回转变幅机构、液压及气动系统、机架和支撑装置、悬吊装置和司机室等主要机构组成(图1)。抓斗为多瓣(48瓣)式,通过刚性框架或连接在气缸上的链条悬吊在动臂上的提升钢绳上,由活塞带动耳盘传动开合,或者提升钢绳悬吊耳盘,由气缸通过拉杆传动开合。抓斗提升由液压缸、钢绳滑轮组和容绳筒组成的提升机构实现,靠重力下放;动臂通过支杆铰接在机架立柱上,用液压缸或绞车钢绳沿立柱滑道拉动动臂上端使其开合;由液压缸、齿条齿轮驱动立柱转动实现左右回转,达到井底工作面任意抓岩位置;机架分几层,分别装置液压站、气动装置、回转变幅机构、支撑装置和司机室。工作时,机架用锚杆固定在井壁上,随着工作面下移,通过悬吊绞车沿井壁下放,锚固后再作业;作业结束提升到一定的安全高度。其优点是吊运方便,距工作面近,容易对准吊桶。常用斗容为0.20.65m,适于直径为46.5m的井筒掘进。抓岩效率可达1660m/h。中国生产有0.40.6m斗容的靠壁式抓岩机。
