| Abstract: | Pneumatic slip replace the traditional slip with the virtue that it have reasonable structure, easy operation, safety at work etc., The pneumatic slip applied more widely. This paper elaborate the structure and working principle of the pneumatic slip. Analyzing the slip body and drill stems in working state though finite element. The results show that the pneumatic drill pipe slips can clamp the drill pipe well without crushing, the slip body has a little deformation, will not dmnaged. This paper verified the working safety and reliability of pneumatic slip. |
