可伸缩带式传输机的结构设计
摘要
早在20世纪60年代，就已出现带式输送机应用于物品。从20世纪70年代至今，带式输送机已经在矿物运输中逐步取代汽车运输,成为了散状货物的主要运输设备。带式输送机在各个领域出的技术不断推进，扩宽了带式输送机的应用范围。而可伸缩带式传输机是应用最为普遍，传输物料最为高效的一种传输机机型。它既有物料搬运量大,输送时间长,连续交通运输的特点,也容易达到集中与自动化的目标。尤其在煤矿事业上的应用广泛,可伸缩履带传输机已经发展成为煤矿开采时必不可少的一种设备。其中主要内容包括对于使用可移动伸缩履带式油料传输机的专用皮带和油料传送器产品种类的结构选择,传动装置的结构设计,中间架和支撑架的结构选择与重量计算,张紧传动装置的重量计算,传动装置的结构选择,托辊和滚筒的结构选择与重量计算等,并且对可伸缩带式传输机的整体结构以及工作原理做出了概述。可伸缩式皮带传输机主要依靠滚筒传动时通过摩擦力来传递皮带的运动,并且还在其结构上加上了存放带式装置,实现了结构的伸缩功能，时输送机能够伸长缩短，以达到不同输送距离的目的，提高工作效率，减少工作人员所需的操作，具有一定的实践价值。

Structure design of telescopic belt conveyer
Abstract
As early as the 1960s, belt conveyor has been used in goods. Since 1970s, belt conveyor has gradually replaced automobile transportation in mineral transportation and become the main transportation equipment of bulk goods. Belt conveyor technology in various fields continues to advance, expanding the application range of belt conveyor. The retractable belt conveyor is the most widely used and the most efficient one. It not only has the characteristics of large material handling capacity, long conveying time and continuous transportation, but also easy to achieve the goal of centralization and automation. Especially in the coal mine industry is widely used, telescopic crawler conveyor has developed into an essential equipment in coal mining. The main contents include the structure selection of the special belt and oil conveyor using the movable telescopic crawler oil conveyor, the structure design of the transmission device, the structure selection and weight calculation of the intermediate frame and support frame, the weight calculation of the tension transmission device, the structure selection of the transmission device, the structure selection and weight calculation of the idler and roller, etc, And the overall structure and working principle of the telescopic belt conveyor are summarized. The retractable belt conveyor mainly relies on the friction force to transfer the belt movement when the roller is driving, and the storage belt device is added to its structure to realize the retraction function of the structure. The conveyor can be extended and shortened to achieve the purpose of different conveying distances, improve the work efficiency and reduce the operation required by the staff, which has a certain practical value.
