摘   要

     随着现代科技的不断发展、进步，我们的矿用机械的科技水平也有了进一步的提高。连续式履带装煤机就是近几年发展起来的新型矿用装煤机械，连续式履带装煤机是集装载、运输、行走于一体的全液压装载设备。可进行连续的作业，还可与矿车、刮板输送机和带式输送机配套使用。即可在井下使用，也可用于地面煤场做装载。本设计是对连续式履带装煤机的装运部进行设计，装载部采用的是星轮装载，运输系统采用刮板输送机，装载部和运输部共用一组液压马达驱动，取消装载减速器，使机器结构更加紧凑，运转更加协调，减少了故障。星轮装载是近几年发展起来的，与蟹爪式相比有明显的优点。运输部根据需要选用的圆环链为中单链，以适应井下复杂多变的巷道情况，可以进行水平方向的转动。本设计主要是对装载部星轮、刮板输送机以及驱动装置进行了科学的设计。正文中首先介绍了装煤机的各种类型和发展趋势，对本次设计中的装煤机原理进行了介绍，其次是三个主要部分的设计计算，并对关键部分进行了强度校核。最后讲解了连续式履带装煤机的安装、使用和维护等方面的注意事项。

Abstract
with the unceasing development and improvement of modern science and technology , our mineral machinery technical level has got the further enhancement.The continuous-type caterpillar band coal loading-machine is the new mineral coaling machinery which begins to develop in recent years, the continuous-type caterpillar band coal loading-machine is entire hydraulic charging equipment which is the collection of loading, the transportation and walks in a body.It can not only do the continual work, but also be used with the mine car, the scraper conveyer and the belt conveyer .That is to say,it may use in mine shaft, also use in the ground coal field to load. The design mains design about the loading-machine department of continuous-type caterpillar band coal-loading machine, the loading department uses the spider loading, the transportation system uses the scraper conveyer, the loading department and the department of transportation uses in common a group of oil motor to actuate, to take the place of the reduction gear, which makes the machine structure to be more compact and the revolution to be more coordinated, reduced the breakdown.The spider loading develops in recent years.Compared with the the crab claw type,it has the obvious merits . According to the need,the round endless chain used in the department of transportation is the single chain so as to adapt the complex changeable tunnel situation in mine shaft. It may rotate in the horizontal direction .The design mainly design about the spider of the load department , the scraper conveyer as well as the drive The main text first introduced each kind of type and the trend of development of coal loading-machine, it introduced coal loading-machine principle, next is design calculations about three main part, and carried on the intensity examination to the essential part. Finally it explained continuous-type caterpillar band coal loading-machine installment, use and maintenance and so on.
