EMULATION OF THE STRUCTURE OF DQ30Y DRILLING-WORKOVER DUAL-PURPOSE TOP DRIVE DEVICE

The research works on the structural characters, working mechanism and structure emulation of a drillingworkover dual-purpose top drive device which is driven by fullhydraulic way and can satisfy the operations in slim-hole drilling, directional drilling, side-tracking and well workover, etc. is presented in this paper. The emulation research on the structure of DQ-30Y drilling-workover dual-purpose top drive device has been realized by adopting the automatic design software (Pro/engineer) in the process of developing this device and through setting up the 3-D solid model of each parts and component, the structure assemblage, the interference inspection and the mechanics analysis. The existent problems in the design and assemblage of this device′s parts and component have been found out, the design proposal has been promptly altered and the found problems and the proposals for modification have been informed to the developmental unit, shortening, thus, the development cycle of this product, reducing the development cost and raising the realiability of this product and its competitive power in the market.
