钻机旋转式升降机架设计与分析

IA rotary lifting frame is designed for a kind of drilling rig which can not drill comprehensively. Equipped with the rotary lifting frame, the drilling rig can achieve comprehensive drilling easily and there is a certain adjustment range in the vertical direction. The scheme of the frame is designed and the work flow of the frame is introduced first in this paper. Secondly, the structural of the frame is designed and calculated and the three-dimensional model of the frame is established. Finally, the frame is analyzed by finite element method. The results showed that the design of the frame satisfy the strength requirements. The highlight of the design is hydraulic supporting at the center of mass of the drilling rig, which can flexible rotate and improve the workplace for the drill operation. This design can also be used as a design reference which has some practical value.
