文档介绍：矿用带式输送机结构设计及仿真
摘要
带式输送机是一种连续运输机械,也是一种通用机械。带式输送机被广泛应用在港口、电厂、钢铁企业、水泥、粮食以及轻工业的生产线。即可以运送散状物料,也可以运送成件物品。本次设计的矿用带式输送机主要用来承担煤矿井下巷道短距离的煤炭转运任务。设计过程严格遵循带式输送机的一般设计原则。首先对带式输送机作了简单的概述,接着分析了带式输送机的选型原则和计算方法,然后根据输送物料的特性和给定的工作条件确定了带式输送机的整机结构,并对驱动装置和工作部分的主要零部件进行选型计算和强度校核,确定了传动滚筒所需圆周驱动力及皮带的张紧方式、张紧力大小等。普通型带式输送机由六个主要部件组成:驱动装置、工作部分、改向装置、机架、拉紧装置以及输送带。由于井下工作环境恶劣,设备运行工况复杂,所以在设计过程中需要考虑各种可能出现的因素,并计算最危险工况下运输机的各项参数,采取相应措施,为带式输送机正常可靠的运行提供有效保证。

Design and Simulation of mine Belt Conveyor Structure
Abstract
Rubber belt conveyor named belt conveyor also named belt machine,is a continuous transportation machinery, and is also a kind of general machinery. Rubber belt conveyor are widely used in port, power plant, steel enterprise, cement, food and light industrial production line. Namely can transport disper- ses the shape material , also can carry as articles. The belt conveyor designed this time is mainly used for transporting the coal at a short distance in the coal mine roadway underground. The design process strictly follow the general des- ign principles of the belt conveyor. At first, it is a simple introduction about the belt conveyor. Next, it is an analysis of the belt conveyor selection principles an- d calculation methods. After that, according to the material features and working conditions given, the whole structure of the belt conveyor was determined. Then it is the calculation and strength checking about selecting driving device and the ponents in the conveyor. The circumference driving force of the drive roller、the tensioning type and the amount of tensioning force were also deter- mined . The ordinary belt conveyor consists of six main parts: Drive Unit Work- ing part、Delivery End、Intermediate Structure、Loop Take-Up and Belt. As a result of underground working environment and plexity of equipment operating conditions, it is necessary to consider every kind of possible working
conditions during its design and calculate the parameters in
