摘   要

     带式输送机是现代物料连续运输的重要设备，是连续运动的无端输送带运送货物的机械，用胶带作为输送带的带式输送机称为胶带输送机，简称胶带机。它是提升和运输机械的重要组成部分，它具有结构简单、成本低、运输距离长、效率高的优点。其主要用于冶金、采矿、煤炭、电站、港口以及工业企业。它将为我国各矿业装卸工作的机械化、现代化作出越来越大的贡献。
现有技术中煤矿井下普掘矸煤运输设备以刮板输送机为主，其缺陷是容易出现卡链条、断链条、机头链轮断齿，卡刮板、断刮板、底链易出槽等故障。另外，由于机器笨重，安装撤除环节复杂，设备故障率高，造成工人劳动强度大，工作效率低，配件投资多等问题。再者是刮板运行过程中矸石与刮板对溜槽的挤压或刮卡，容易产生火花，形成安全隐患，不利于安全生产。
本文针对这种情况主要介绍了一种煤矿井下掘进矸煤运输简易皮带机。首先，介绍了带式输送机的工作特点、发展概况、工作原理及分类；其次，介绍了胶带的摩擦传动原理；最后，根据带式输送机的工作条件对其进行了详细的设计计算，如驱动装置、机架等。此带式输送机结构简单、操作装拆卸方便、成本低、设备安全可靠，在煤矿井下广泛应用。

ABSTRACT

Belt conveyer is one of most equipment used in bulk transport. Belt conveyer is continual motion machine of sideless conveying articles, using rubber belt to be conveyer belt is called rubber belt conveyer, and brief name is sealing-tape machine. Belt conveyer is an important component part of lifting and transport machinery. Its structure is very simple, and has low cost, long distance transport and very high productivity. It is mainly used in metallurgy、mining coal、power plant、port and industrial enterprises. It will make the bigger and bigger contribution for our country various mining industry loading and unloading mechanization and modernization.
In the existing technology, in coal mine common digs the gangue coal transport vehicle is mainly the scraper conveyer, its flaw is easy to appear the card chain link, to break the chain link, and the nose chain wheel breaks the tooth, the card scraper, breaks the scraper, the bottom chain is easy to overflow the breakdown and so on. Moreover, because machine is unwieldy, installment and removal link is complex, equipment failure rate is high, it creates the worker’s labor intensity in a big way, the working efficiency is low, the fitting invests is big and so on. Furthermore, in the scraper movement process the extrusion or blows the card of the gangue and the scraper to trough is easy to produce the spark, to form the hidden danger, is disadvantageous to the safety in production.
This article mainly introduced one kind of simple coal mine shaft tunneling gangue coal transportation belt conveyer in view of this kind of situation. First, it introduced the work characteristic of belt conveyer, the development survey, the principle of work and the classification; Next, it introduced the adhesive tape friction drive principle; Finally, it has carried on in detail design and calculation according to the working condition of belt conveyer, like drive, rack and so on. Its structure is simple, the installs and disassemble is convenient, the cost is low, the equipment safe is reliable, in coal mine shaft it is applied widely.
Keywords: belt conveyer; work principle; development survey; drive devices
