摘要

Currently, horizontal directional drilling, impact spear, horizontal spiral drilling,rnrammer and other technologies are used for the underground trenchless laying ofrnsmall-diameter and middle-diameter pipelines. At first, after comparing the workingrnmethod of puncturing mud dragon robot with impact spear which tracks can berncontrolled. The pneumatic impact mechanism of puncturing mud dragon robot wasrndesigned and deduced its mathematic model and used the numerical value method tornsolve its dynamical process; Second, analyzed the influence between the mainrnparameters such as piston displacements at different position, piston mass, systemrnpressure and exports those are impact energy, impact frequency, impact velocity andrnreturning velocity, and pointed out their connection and restrict. Third, the optimizerndesign on the pneumatic impact mechanism was put up based on the shortest ofrnpiston journey and get the optimize design parameters. In the end, the performancerntests on impact force, impact frequency and so on for the impact mechanism wererndone, and validated its rationality.
