早在20世纪70年代,就已经出现了运输距离达到100的带式输送机输送线路。近年来,带式输送机在矿山运输中已经逐渐开始取代汽车和机车运输,成为散装物料的主要运输装备。不断出现新型带式输送机,拓宽了带式输送机的应用领域。可伸缩带式输送机是连续输送物料机械中效率最高、使用最普遍的一种机型,是巷道掘进运输和采煤工作面顺槽运输的主要设备。在煤炭、冶金领域中,可伸缩带式输送机得到了广泛应用。
为适应这一变化,本文主要针对带式输送机中的可伸缩带式输送机进行了结构设计,包括可伸缩带式输送机输送带的选择、中间架的选择计算、传动装置的设计、张紧装置、收放胶带装置的计算、托辊以及滚筒的选择计算等,并针对其结构及其工作原理作了概括性总结。可伸缩带式输送机利用传动滚筒与输送带之间的摩擦传递动力,在结构上增加了储带装置,这样可以实现整机的伸长和缩短,从而提高了工作效率,增大产量,减少人员操作,具有一定的工程实践价值。

Abstract
In the early 1970’s, the belt conveyor transportation route with the distance of 100 has already appeared. In recent years, belt conveyor has gradually replaced the automobile and motorcycle in the mine transportation, and es main equipment of bulk materials. Constantly appeared new type belt conveyor has exploited the application of belt conveyor. The flexible belt conveyor is one of the highest、 mon use continuous transportation equipment, which is the main equipment in lane dig and coal face sequential slot transportation. The flexible belt conveyor has been widely used in coal, metallurgy fields.
In order to adapt this change, this paper mainly carries on the flexible belt conveyor structure design of the belt conveyors. includes the choice of the belt, the choice and calculation of the middle shelf, the design of transmission device、the calculation of the tighten device and draw in and out belt device、the choice and calculation of the support roll and cylinder, then give a summarized conclusion of its construction and work principle. The flexible belt conveyor transmits power depending on the friction between the transmission cylinder and the belt, adding belt storage device in structure, which can realize the extension and shorten, thus raises the working efficiency increases the output, reduces the personal operation, which has some engineer practice value.
