摘要:本次毕业设计是关于胶带输送机的设计。首先对胶带输送机作了一个简要的概述;接着分析了胶带输送机的选型原则和计算方法;然后根据这些设计准则与计算选型方法按照给定参数要求进行选型设计;接着对所选择的输送机各主要零部件进行了校核。
the use of the earlier studies , mainly used in ports , steel mills, cement plants , mines and other occasions. Coal belt conveyor is the most ideal and efficient continuous transportation equipment, especially high yield large modern coal mines, coal belt conveyor has become an efficient mining equipment, electromechanical integration technology and key equipment .国内外长途地面输送机皮带输送机和早期的研究,主要应用于港口,钢厂,水泥厂,矿山等场合使用。煤炭皮带输送机是最为理想和有效的连续运输设备,尤其是高产的大型现代化煤矿,煤带式输送机已成为高效的采矿设备,机电一体化技术和关键设备。
Foreign belt conveyor technology development mainly in three aspects: ( 1 ) belt conveyor functional diversification , expansion range of applications , such as large angle belt conveyor ; ( 2 ) belt conveyor technology itself to the long haul , large capacity, high belt speed and other large belt conveyor direction ; ( 3 ) key parts belt conveyor itself to high performance, high reliability direction. In the coal mine , due to environmental conditions, its technical indicators belt conveyor belt conveyor than terrestrial index is low. Foreign commonly used belt conveyor main technical indicators such as the table below.
From the 1980s onwards, China coal mine belt conveyor also been great development of the belt conveyor key technology research and development of new products have achieved gratifying results , conveyor products continue to increase, from stereotypes SDJ , SSJ, STJ, DT series developed into multi-function , to adapt a variety of special-purpose conveyor series, but this stage of development after 1970 was largely based on the introduction of the belt conveyor and modifications , the main structure is not large changes. After entering the 1990s , with the development and needs of modern coal mine , China's large angle belt conveyor , high efficient working face telescopic belt conveyor and long- haul , large capacity belt conveyor and its key technologies, key Parts for the theoretical research and product development, using dynamic analysis techniques and intermediate driver and intelligent control technology , successfully developed a soft start and braking device and PLC control as the core of explosion-proof electric control device . As China's high-yield and efficient mine coal development , coal mine belt conveyor to the current shown in Table 1.2 has reached major technical indicators .
It consists of conveyor belts , drives , roller, rack , cleaning, tensioning devices and brakes and other components. The belt around the drive pulley and tail bend pulley belt formed Promise ring closure . Upper and lower two stocks were supported on conveyor roller and a lower roller on . Belt tensioning device to ensure the normal operation of the desired tension . Operation, the drive roller driven by the friction belt operation. Material mounted on a conveyor belt moving along the conveyor belt . Often use the stock conveyor belt material , and in the belt around the head drum changes direction unloaded. If necessary , you can use a special unloading device at any point in the middle of the conveyor for unloading.
