摘 要可伸缩带式输送机在工业中有着广泛的应用，它是工业生产中实现连续化、规模化、自动化、现代化必不可少的设备此次进行了可伸缩带式输送机的整体结构设计，并确定给出了该输送机主要零部件结构参数及其计算方法根据给定的参数设计并计算选用可伸缩带式输送机的标准零部件构成输送机的整机，在张紧装置中采用了液压自动调整装置，并进行了主要零部件的强度校核根据带式输送机的主要组成及各部分特点，首先对其传动部分进行设计计算，然后选择合适的驱动装置，最后确定张紧装置的结构，并对其进行了设计计算可伸缩带式输送机主要用于煤矿井下运输，综合考虑各方面的因素，采用合理的驱动方案、合理的张紧装置，软启动装置组合，有效保证带式输送机的可靠运行关键词：可伸缩带式输送机；张紧装置；传动装置Abstract With the development of science and technology and the rise of distance on the conveyor and the traffic has a new and higher requirements, our design of a large belt still in its infancy, the belt conveyor design, manufacture and applications, advanced level in China and abroad, there is still a large gap between domestic manufacturing belt in the design process there is much to be desired. Thus, large transportation machinery, especially the belt conveyor design theory and methods of in-depth analysis is necessary. This article was flexible belt conveyor design the overall structure and to determine given the major components of the conveyor structure parameters and their calculation. Designed according to the given parameters and calculate the standard belt use scalable components constitute a fixed level of the transport belt conveyor machine, used in a hydraulic tensioning device automatically adjusts the device, and make the main parts the strength analysis. Under the belt and the part of the characteristics of the main component, the first part of its drive to design calculations, and then select the appropriate drive, and finally determine the tensioning device of the structure and design calculation was carried out. The design is mainly used for coal mine transport, considering all factors, adopt a reasonable driving scheme, means braking and soft start device combination, effective to ensure reliable operation of the belt conveyor.
