Title Design of an telescopic springboard used in oil platform

Abstract

Offshore Oil platform telescopic springboard can be understood as the full rotary telescopic bridge device is the boarding ladder.As the nonstandard equipment,it is mainly applicable to the adoption and migration of personnel and materials of offshore drilling platform and life platform. The main content of this thesis is to design a full hydraulic boarding ladder and all the movements of the device mainly included the main rotary motion, the variable amplitude motion and the telescopic movement is controlled by the hydraulic system. The design content mainly includes the design of mechanical structure and the hydraulic system design, draw all the parts of the whole device by the drawing software and complete the motion simulation and complete Finite element analysis of stress and strain of important local component, which includes tubular pedestal and the bridge.at the same time, we should complete the design of hydraulic system, which drives the variable amplitude cylinder、rotary motors and telescopic motor.

Keywords Offshore Oil platform telescopic springboard Boarding ladder
