A Washing Plant Conveyor Trestle Steel Truss Design And Cutting Optimization

In recent years,due to the improvement of the level of industrial production, the use of cars for material transport can not ensure the continuity of production, and higher transportation costs. Continuous transport belt, pipe band will not only ensure a continuous supply of materials, but also to achieve automatic control, greatly reduce transportation costs. This has prompted the bearer of such machinery and equipment trestle in coal, cement, metallurgy and other production areas are widely used. And reinforced concrete brackets supporting the gallery body compared to brick-concrete structure, steel truss trestle with a light weight, span, small footprint, high degree of industrialization, beautiful appearance, good seismic performance, short construction period and a series of advantages.In this paper, stcad tube structure design software to a coal mine belt trestle truss design as an example, the truss trestle analyze and study.Firstly, based on the project background, we put forward the overall design. Including the composition of the overall structure of the bridge, the overall force transmission route, and arranged to determine the scope of the bridge span. secondly the composition of the bridge’s two main structure is the bridge trusses, truss support, refine the design, including the determination of its specific dimensions, trestle and the support structure trestle bearing joints, etc. OK, Then,the two parts are structural modeling, computational analysis, and finally to the problem encountered in the design, the relevant aspects of the specification has not been clearly defined computing unit selection,chord rod arrangement in the form of web,an gleand other aspects Comparative analysis, summed up the appropriate approach.The entire trestle reasonable force,safe and economic.Analysis of results: trestle truss and frame can be seen as both structures independent modeling, analysis and calculation. Load input simple rod axial deformation in, to take advantage of the strength of the steel member, played rod characteristics.
