1、摘要:皮带机是带式输送机的简称,有固定式和移动式,结构简单,效率高。以挠性输送带作物料承载和牵引构件的连续输送机械。一条无端的输送带环绕驱动滚筒和改向滚筒。两滚筒之间的上下分支各以若干托辊支承。物料置于上分支上,利用驱动滚筒与带之间的摩擦力曳引输送带和物料运行。适用于水平和倾斜方向输送散粒物料和成件物品,也可用于进行一定工艺操作的流水作业线。结构简单,工作平稳可靠,对物料适应性强,输送能力较大,功耗小,应用广泛。全套图纸,加我国生产制造的带式输送机的品种、类型较多。在“八五”期间,通过国家一条龙“日产万吨综采设备”项目的实
2、施,带式输送机的技术水平有了很大提高,煤矿井下用大功率、长距离带式输送机的关键技术研究和新产品开发都取得了很大的进步。如大倾角长距离带式输送机成套设备、高产高效工作面顺槽可伸缩带式输送机等均填补了国内空白,并对带式输送机的减低关键技术及其主要元部件进行了理论研究和产品开发,研制成功了多种软起动和制动装置以及以PLC为核心的可编程电控装置,驱动系统采用调速型液力偶合器和行星齿轮减速器。关键词:海运、港口装卸机械、散货装卸机械、装船机作用、机理、类型、结构以及设计任务Abstract:Beltconveyorbeltconve
