通过对ZJ45和ZJ45J钻机绞车的提升特性,一次起钻的机动时间和功率利用程度的比较计算,作者分析了机械传动钻机绞车和变矩器传动钻机绞车的工效问题。文中介绍的方法,还可用于其它类型钻机绞车的工效计算。
By comparing the lifting characteristics of ZJ45 and ZJ45J winch winches, the maneuvering time and the degree of power utilization of a jackhammer, the author analyzes the work efficiency problems of the winch of the mechanical drive winch and the torque converter drive drill. The method described in this article can also be used for ergonomic calculations of other types of rig winches.
