Research on the Loaded Traveling Erecting Equipment of Flexible Track on Cable of Suspension Bridge
With the development of suspension bridge construction in China to the direction of large span,heavy segment and complex construction background,traditional girder erection equipment will gradually become an important constraint.In this paper,a type of loaded traveling erecting equipment of flexible track on cable is proposed.The equipment has the characteristics of integrated transportation and erection and relying on the main cable,and has high research value.In the paper,the general design idea of the equipment is introduced,the influence of the main cable shape change on the operation of the equipment during the girder erection is analyzed,the stress characteristics of the traveling load-bearing cable are studied,the variation law of the main structural parameters when the equipment is walking is explored,and the working principle of the flexible track system on the cable is revealed.Finally,the girder erection process and its application value in project practice are briefly analyzed,which shows that the loaded traveling erecting equipment of flexible track on cable has good technical feasibility and application prospect.
