Parametric Design Of The L-screw Ship Unloader

Energy conservation and environmental protection as the most concern intoday’s society, the constraints on the port industry is particularly prominent. Therapid development of the economy prompted port handling equipment must betoward the direction of large-scale, specialization and automation, the traditionaldischarging equipment due to the high energy consumption, environmental pollutionhas already can not adapt to the requirements of The Times, screw ship unloader inthis context are widely used in port.It due to their high productivity and utilizationcoefficient, easy to realize the automation of material transportation, because it isenclosed conveying at the same time, the environmental pollution is small, so thescrew ship unloader is widely used for energy saving and environmental protectionhas important significance.Screw ship unloader advantage is obvious, but its design is also apparentdifficulty. Because of the complex structure of spiral unloaders, many designparameters and high degree of correlation between parameters, causing the programto be constantly revised in the design process, greatly increasing the difficulty ofdesign, traditional methods to face such a complex design environments becomestretched. On the one hand is a large demand for screw unloaders, on the other handis designed to screw unloaders complex calculations, the rapid development ofcomputer technology of parametric design method provides an opportunity to solvethis problem. Parametric design method parameter-driven approach to calculate thesize constraint model for product design, can be quick and easy to complete theproduct throughout the design process.In this paper, take the new type L-screw ship unloader for example, introducesin detail the L-screw ship unloader parametric design system.The article expoundsthe research background, purpose and development situation at home and abroad,related to this topic of old and new design method was introduced in detail in theapplication in the design of the screw ship unloader. In accordance with the overallof the L-screw ship unloader design as well as the agencies have done a lot of work.In the overall design of the main sizes of the transmission system design, stress analysis was carried out on the machine, wheel pressure, resistive overturningstability checking calculation. In the mechanism design of horizontal spiral sections,vertical screw, pitch balance system, slewing mechanism, operation mechanism ofthe key performance and selection of parameters of design and calculation. In systemdesign, in detail elaborated the system design thought and work processes, this paperintroduces the main interface of this system and the composition and operationprinciple of child Windows, the process of programming code are made clearinstructions, on the basis of the above task to develop L-screw ship unloaderparametric design system.This topic development of L-screw ship unloader parametric design systeminterface aesthetics, convenient operation, quickly used in the design of the L-screwship unloader, system running stability in the process of design, compared with thedata which has been completed in the design, the system design data accurately.Thissystem not only reduces the L-screw ship unloader design difficulty, but alsoimprove the design efficiency, with great practicability.
