中文摘要 拌混凝土搅拌站是一种临时建筑，具有可拆迁性，在结构选型上应考虑快速施工、安装和拆除方便，所以主站结构选用装配式钢结构。我们所设计的搅拌站由骨料配料系统、平皮带输送系统、斜皮带输送系统、搅拌机、螺旋输送机、水泥储料仓等部分组成。 带式输送机的牵引构件和承载构件是一条无端的胶带，交代绕在机架两端的传动滚筒和改向滚筒上，由起张紧装置张紧，在沿交代长度方向上用上托辊和下托辊支撑，构成封闭循环线路。当驱动装置驱动传动滚筒回转时，由传动滚筒与胶带间的摩擦力带动胶带运行。 储料仓是存放散装水泥的地方，通常有仓体、塔帽、支架等部分组成，本搅拌站使用的是SNC100F水泥储料仓，可装水泥的重量为100吨。其中塔帽部分主要设备有除尘器。仓体主要构件有内外部检修梯、下料口、破拱装置组成。支架部分的重要部分有中间的检修平台，地脚螺栓等。 储料仓设计的重点就是出料口的破拱装置，同时还要对仓体和底部支架进行强度计算校核，防止水泥仓胀仓和支架断裂引发安全隐患。 储料仓支架钢结构的柱脚用通常的铰接形式，仅传递垂直力和水平力。架柱之间的横梁、斜撑与柱的连接按铰接设计，柱脚按铰接点考虑，钢架结构自身稳定性较好，承受竖向荷载和水平风荷载。平台主次梁间均为焊接。 在进行钢结构搅拌站设计时，只做平面静力计算，通常利用平面力学的近似解法求解，这种方法是在计算手段不完善，受到诸多前提条件限制的情况下进行的处理。计算结果比较粗糙。设计中的具体方法是:首先将仓体整体结构简化为平面模型，然后加上恒载、风载、地震载荷，经荷载组合得到最不利的效应组合，最后通过强度、稳定、挠度验算确定梁、柱的截面。 关键词： 水泥仓 搅拌站 皮带机  ABSTRACT Mixing the concrete stirs the station to be one kind of building temporarily , and to possess removable nature moving , and it is convenient that the worry taken an entrance examination on the structure mould selecting is constructed , installs and being dismantled quickly , and the structure chooses the assembly type steel structure so owner stands . That we design stirring standing forms by the part such as aggregate mix ingredients according to a recipe system , flat leather belt transport system , oblique leather belt transport system , mixer and spiral conveyer and cement Chu Liaocang etc The type taken conveyer tows to construct the part and bears the weight to be constructed the part to be an adhesive tape for no reason , and to hand over the transmission roller that winds at the frame both ends and changes to the roller , and the cause case is tightly installed tightly , is made use of on follows handing over the length direction carrier roller with under the carrier roller puts up , forms the closed DO loop circuit . Drive the adhesive tape operating by frictional force between transmission roller and adhesive tape when the drive drive transmission roller revolution Chu Liaocang is the place leaving unpackaged cement , and having parts
