一、概述在各类地质钻机中,钻架是一个重要的组成部分,因为钻机工作时,钻架要承受全部大钩载荷,还要承受风载及靠放钻杆的水平分载,同时,钻架本身自重较大,在整个钻机重量中占有相当比例,所以合理设计钻架,对提高钻机可靠性,安全性及各项综合指标均有着直接影响。 I. Overview In all types of geological drilling rig, the drill is an important part of the drilling rig work, the drill rig to bear all the hook load, but also to withstand the wind load and the horizontal load by putting the drill pipe at the same time, The weight of the drill frame itself is relatively large, which occupies a considerable proportion of the weight of the rig. Therefore, the rational design of the drill frame has a direct impact on improving the reliability, safety and comprehensive indexes of the drilling rig.
