摘   要

     隨著現代科技的不斷發展、進步，我們的礦用機械的科技水平也有了進一步的提高。連續式履帶裝煤機就是近幾年發展起來的新型礦用裝煤機械，連續式履帶裝煤機是集裝載、運輸、行走于一體的全液壓裝載設備。可進行連續的作業，還可與礦車、刮板輸送機和帶式輸送機配套使用。即可在井下使用，也可用于地面煤場做裝載。本設計是對連續式履帶裝煤機的裝運部進行設計，裝載部采用的是星輪裝載，運輸系統采用刮板輸送機，裝載部和運輸部共用一組液壓馬達驅動，取消裝載減速器，使機器結構更加緊湊，運轉更加協調，減少了故障。星輪裝載是近幾年發展起來的，與蟹爪式相比有明顯的優點。運輸部根據需要選用的圓環鏈為中單鏈，以適應井下復雜多變的巷道情況，可以進行水平方向的轉動。本設計主要是對裝載部星輪、刮板輸送機以及驅動裝置進行了科學的設計。正文中首先介紹了裝煤機的各種類型和發展趨勢，對本次設計中的裝煤機原理進行了介紹，其次是三個主要部分的設計計算，并對關鍵部分進行了強度校核。最后講解了連續式履帶裝煤機的安裝、使用和維護等方面的注意事項。

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.
