25 Tons of Horizontal Directional Drilling Promoting Mechanism Design
Abstract :Horizontal directional drilling machine is not digging in the surface conditions, the laying of a variety of underground utilities (pipelines, cables, etc.) of a construction machinery.This thesis introduce the charcterristic of horizontally diretionalt drilling to you ,and how construct through the earth ,also the development of orizontally diretionalt drilling.and so on.In this thesis ,the main task is to design the feed mechanism,the choose of Driving method ,the design of a chain and a shaft ,also design for fatigue strength like bolts and bond.
