文档介绍：摘要
本文在参考一般输送机设计基础上,分析了常见的小型带式输送机特点,设计了一套集伸缩、移动、变幅三种功能合一的单元组合式传动输送机创新设计方案,尤其对伸缩方案进行了细致的分析和讨论。
文章首先介绍了国内外带式输送机的发展状况、输送机发展趋势和设计目的和意义,分析了常见的伸缩输送机的伸缩形式以及用以实现伸缩的传动形式。设计是基于QD80轻型带式输送机设计方法,其中部分零部件从QD80输送机零部件种选用,伸缩机构为自行设计,采用螺母螺杆传动形式达到输送机伸缩目的,通过计算确定了伸缩机构的相关参数,对输送机的各种运动状态进行了模型简化与受力分析,计算结果保证一些极限情况下的机构的安全性。设计了一套通过电机、齿轮减速带动螺母螺杆运动的传动机构。
本文也对移动、变幅做了相关设计计算,对设计一些零部件采用了采购或定制的方式并对移动输送机的创新和改进做了展望,特别提出今后可能具有良好发展前途的改进设想。

Abstract
This paper based on the design for ordinary belt conveyor, analyzed the characteristic mon small belt conveyors, designed a bined transmission conveyor innovative plan which integrated three functions such as telescopic, mobile and change angle, especially did a careful analysis and discussion on telescopic plan.
The paper first introduced the developing situation of belt conveyor at home and abroad and the trend of its development and design purpose and significance, mon telescopic and transmission form in telescopic conveyor. The design process was based on the method of QD80 small belt conveyor, some part of parts were selected from QD80 standard parts, the telescopic agency used screw nut transmission form to achieve the conveyor to expand and contract, relevant parameters were confirmed by calculation. Design a transmission agency with electric motor and gears to drive screw nut agency.
The paper also calculated parameters of mobile and change angle functions, some parts would be purchase or have custom-made, and had expectation on future innovation and improvement.
Key words: Belt-conveyor telescopic mobile change-angle
