Abstract: Aiming at the present problems in the process of underground gas pipeline installation and demolition work in the complex, this paper designed a special gas pipeline can solve the problem of hoisting equipment, reduce the labor intensity of the workers. Secondly, from the perspective of structural design, the equipment for the analysis of structural strength based on the mechanical analysis, in order to meet the requirements of structural strength, the structure of the device has large design margin, which can be light weight. In this paper the particle swarm algorithm is applied to the lightweight design of the structure, a lightweight structure design model based on particle swarm optimization algorithm, and the optimization calculation is given a set of safety and economy of the dual attributes of structural design parameters.
