带式运输机设计
摘要
带式运输机是一种重要的物料搬运机械，是在沿一定输送路线设置的输送带上输送一定种类货物或人员的机械装置，带式输送机可以减轻人力物力投入，在短时间运送大批散粒物品，提高工作效率。目前带式输送机的应用已经十分广泛，在许多生产过程中成为关键或重要的辅助设施。
带式运输机靠驱动滚筒对缠绕在其上的输送带的摩擦力驱动。输送机两端的滚筒和拉紧装置将输送带张紧，滚筒和输送带之间产生强大的压力，驱动滚筒旋转从而产生摩擦力。输送带承受的张力由各种阻力组成，并且是机械功耗所在，计算出各种阻力的总和即可求得该输送机的功率。输送带上张力必须足够大，以免磨擦力太小输送带打滑或者输送带下垂过多。因此输送带必须有一定的韧度，以防止被巨大的张力拉断。
输送带在输送物料时，在托辊组上保持II形或其他形状以保证物料不会撒出。在新型的圆管带式输送机中，输送带在承载段呈圆管状，可更好地将物料密闭起来，并且还有很多其他优点。
输送机设计基本参数：运输能力、垂直和水平运距、运动速度、各大机构的尺寸大小等。输送能力是设计、选用输送机械的主要依据，水平、垂直运距关系着驱动功率的计算，它们是设计原始数据。带式运输机的运动速度指的是运输机牵引各大机构运动的速度，也就是输送带的运动速度，该参数不仅对运输机的输送能力起决定性的作用，与此同时而且还影响输送机的安全度、准确度、能否有效快速的达到运输的目的和作用。在使用运输机时，我们必须根据各类运输机型号、需要被输送的物品的特点以及运输的环境来选择正确的运输机运动速度。主要工作构件主要指带式输送机的带宽，根据设计输送能力来计算和选定。
带式输送机主要由一下各部件来组成：输送带、驱动装置或电动滚筒、传动滚筒、改向滚筒、多边形托辊组、过渡托辊组、框架、锁紧系统、清扫装置、中间架、填料系统、安全保护系统等。设计时必须根据各种参数条件和选用规则来选择使用。
在设计带式运输机时我们必须根据该运输机的工作地点、工作环境以及用户所要求的条件来对其进行客观而合理的设计。

Abstract
Belt conveyor is a kind of important material handling machinery, is along the transport route set conveyor belt conveying a certain types of goods and personnel mechanism, belt conveyor can reduce manpower inputs, in a short time transporting large armies of grain goods, improve the work efficiency. Belt conveyor has on many occasions as key equipment or important auxiliary machinery, can be widely applied.
Belt conveyor by driving drum of the friction winding on the conveyor belt drive. At the ends of the conveyor roller and tension device will conveyor belt tension, strong pressure between rollers and conveyor belt, drive roller rotation to produce friction. Conveyor belt tension under is composed of all kinds of resistance, and mechanical power consumption, calculate the sum of all kinds of resistance can be obtained by the power of the conveyor. Conveyor belt tension must be large enough to avoid excessive friction force is too small or drooping conveyor belt conveyor belt skid. Conveyor belt must have a certain toughness, therefore, in order to prevent the pulled by huge tension.
When conveyor belt conveying material, keep on supporting roller group II shape or other shapes to make sure that the material won't be out. In the new type of belt conveyor, conveyor belt in bearing section assumes the circular tube, can better material closed up, and there are many other advantages.
Conveyor design the main parameters are transmission capacity, vertical and horizontal distance, working speed, the feature sizes of the main components, such as driving power. Design, selection of transmission capacity is the main basis of conveying machinery, horizontal and vertical distance of relations with the calculation of driving power, they are designing the raw data. The work of belt conveyor speed refers to the speed of traction components, the work of the conveyor belt speed, is crucial not only to the transmission capacity, but also influence on the reliability of the conveyor, economy and quality of work, etc. Must be based on different models, the characteristics of material to be delivered and specific transportation conditions to select reasonable working speed. Main work component refers to the bandwidth of the belt conveyor, calculated and selected according to the design of transmission capacity. Driving power depends on the conveying machinery running resistance, reflect the size of energy consumption, the relationship between the belt conveyor power plant size, weight, investment and operating costs.
Components are: belt conveyor belt, driving device or electric drum, drum, drum of haul, polygons, roller, frame, transition roller group, tension device, sweeper, frame, feed hopper, electrical, and safety
protection device, etc. The design and selection rules must be based on various parameters to choose to use.
Belt conveyor must be on the basis of using the site topography, environmental conditions and the user's specific requirements for design.
