| With the rapid development of suspension bridge in China, It's need to face coastal areas that with strong winds, mountain canyons and other natural conditions ect. That is worse in the work environment. deck erection gantry as the stiffening girder bridge vertical lifting method in lifting the special lifting equipment, we must continue to improve their own performance indicators to lifting the increasing difficulty of the work environment, so the design of a strong typhoon in the environment suitable for large tonnage of lifting, the ability to walk more on new deck erection gantry has important practical value.With the research background of the Zhoushan Islands Link works with large bridge-Xihoumen steel box girder bridge project, a new type of deck erection gantry performance indicators and technical parameters have been identified. Summarizing the Existing home and abroad deck u erection gantry design and work characteristics; with the design and comparison of the major components of the program and the hydraulic control system.innovatively design the walking system to allow for the new crane cable walking on their own cable systems, deck erection gantry made in strong wind and typhoon shelter under the main measures and wind equipment design。Finally, the drawing machine was Design and delivery of factory production.Three-dimensional mechanical design software SolidworkS used on the new deck erection gantry for a virtual prototype design, the parametric programming language APDL was use on the programming in ANSYS10.0, ANSYS13.0Workbench software to complete the main structure structure calculation; Finally, the drawing machine was Design and delivery of factory production.At last, the paper introduces a new type of deck erection gantry,sharing wind tunnel tests and conclusions of the crane.completing the whole machine experiment and analysis of the static load test results, set out different design Installing method for different position of the cable crane installed in the bridge -Xihoumen.With the design background of large tonnage and long span suspension bridge stiffening girder lifting in strong typhoon environment, with the use of virtual prototyping, finite element analysis, boundary layer wind tunnel experiments. The design completed to adapt to the environment in the strong winds, large tonnage, lifting, walking on their own new cable set hoisting cable Prototype; It is an important reference for the set of cable suspension bridge cranes and other developed special set of construction machinery. |
