摘要

早在20世纪70年代，出现了100公里运输距离皮带输送线。在最近几年，该矿输送机输送已逐渐开始取代汽车和摩托车运输，一个主要的运输设备散装材料。不断出现的新皮带输送机，皮带输送机拓宽了应用领域。伸缩式皮带输送机是最有效的连续运输机械的材料，最常用的模式是掘进工作面运输及主要设备的煤炭运输。煤炭，冶金，柔性带式输送器已被广泛应用。为了适应这种变化，造纸机结构伸缩式皮带输送机的设计，包括伸缩式传送器选项可供选择的设计和中间帧的计算，传动装置，张紧装置，用于计算一个可伸缩的磁带设备，辊与鼓的选择和计算等，并提出了结构的全面概述以及它如何工作的。使用带拉伸机之间的辊和摩擦传递动力传动，皮带结构增加了存储单元，以使机实现的膨胀和收缩，从而提高了工作效率，提高产量，减少人员操作，具有一定的实用价值工程。

Abstract

Early in the 1970s, there has been 100 km transport distance belt conveyor line. In recent years, the mine conveyor transport has gradually begun to replace the car and motorcycle transportation, a major transport equipment bulk material. Emerging new belt conveyors, belt conveyors broadens the application area. Telescopic belt conveyor is the material in the most efficient continuous transport machinery, the most commonly used model is Heading Face transport and coal transportation of major equipment. Coal, metallurgy, flexible belt conveyor has been widely used. To accommodate this change , the paper machine structure telescopic belt conveyor design, including telescoping conveyor options to choose the design and calculation of the middle frame, transmission device, tensioning means for calculating a retractable tape device, roll and drum selection and calculation, etc., and made a broad overview of its structure and how it works. Using a roller and friction between the belt stretching machine transmits power transmission, belt structure increases the storage unit to enable the machine to achieve the expansion and contraction, thereby improving the work efficiency, increase production and reduce personnel to operate, has a certain practical value engineering.
