2、输送带作为牵引和承载构件,通过承载物料的输送带运动进行物料输送的连续输送设备,它不仅应用于企业内部的运输,也拓展到企业外部的输送,广泛应用于冶金、矿山、港口、粮食和化工等领域。随着工业的发展,对带式输送机的需求越来越大。首先分析了国内外带式输送机的现状与发展。通过工况的分析和各种输送机的优缺点的比较,确定了普通带式输送机为基本结构,改进输送带形状,改向滚筒等的设计方案。通过计算输送带的张力,确定了电机功率;根据料袋的大小确定了输送带的宽度;根据负载情况确定了滚筒和托辊的参数,并分别进行了校核;根据作业空间确定了倾
3、角,由于倾角达到了30°,属大倾角传动,为防止打滑改进了输送带和改向滚筒,并选用了较低的传送速度。设计了输送带的张紧装置和上袋限位装置。最后分析了带式输送机跑偏的原因并提出了纠正措施;并对固定带式输送机安装及试运转方法进行了详细的说明。完成了整个带式输送机的制作,运行结果表明:所设计的带式输送机运行平稳可靠,达到在小空间实现大倾角送料而不打滑的目的,很好的完成了预定任务。关键词:输送带;滚筒;托辊ABSTRACTThebeltconveyeristakesthehaulingandthecarryingpiece
