摘要
【目的】带式输送机作为物料运输机械,在煤矿、电力、化工、冶金、粮食等领域应用广泛。带式输送机为非标设备,荷载影响因素多、变化幅度大,且通过支腿将荷载传递到栈桥楼面,为局部荷载。目前,对栈桥楼面活荷载取值研究较少,相关规范规定针对性不强。【方法】本研究以煤矿行业带式输送机栈桥为研究对象,分析栈桥楼面及带式输送机荷载的组成,各组分的占比及变化影响程度,【结果及结论】归纳总结不同输送带宽度、物料密度、单(双)输送带栈桥的楼面横向等效均布活荷载(主体计算)和纵向等效均布活荷载(楼面体系计算),为带式输送机栈桥的设计提供参考。
As material transportation machinery,belt conveyors are widely used in fields such as coal mines,electricity,chemical industry,metallurgy,and grain.The belt conveyor is a non-standard equipment,with many load influential factors and large variations,and the load is transferred to the stack bridge floor through the outriggers,which is a local load.At present,there are few studies on the value of live load on the stack bridge floor,and the relevant regulations are not very pertinent.In this study,the belt conveyor stack bridge in the coal mining industry was taken as the research object,the composition of the stack bridge floor and the load of the belt conveyor,the proportion of each component and the degree of influence of the change,and the transverse equivalent uniform live load(main body calculation)and longitudinal equivalent uniform live load(floor system calculation)of different conveyor belt trestle widths,material densities,and single(double)conveyor belt trestle were summarized,so as to provide a reference for the design of belt conveyor trestle.
