ZDY4300LP型钻机液压卡盘的设计与应用
|
摘要
液压卡盘是煤矿坑道钻机的关键部件之一,其性能好坏直接影响整机性能。针对目前所使用的液压卡盘存在的一些问题,设计了一种用于ZDY4300LP型钻机的新型液压卡盘。介绍了其主要结构及工作原理,确定了主要技术参数,简述了中心管、卡瓦及片弹簧的设计内容。经工业性试验验证,新型液压卡盘完全满足煤矿坑道钻机的使用要求。
The hydraulic chuck is the key part of the coal mine tunnel drilling rig, its performance directly affects the whole drilling rig. Based on some existing problems of the used hydraulic chuck at present, a new hydraulic chuck was designed for ZDY4300 LP drilling rig. The main structure and working principle were introduced. The main technical parameters were determined. The design contents of central tube, slip and claw spring were described. The industrial tests show that the new hydraulic chuck can completely meet the requirement of coal mine tunnel drilling rig.
