摘    要
      本文針對我國西北地區(qū)礦井的特點，為了適應大斷面斜井快速掘進的要求，從而解決裝載速度不能滿足掘進速度要求的矛盾，進行了耙斗裝巖機的整機設計。論文中以耙斗裝巖機的生產率和鋼絲繩的牽引力為已知條件，通過大量的計算、推理和論證，基本完成了耙斗裝巖機的減速器、工作滾筒、空程滾筒等主要部件的設計工作。其中工作滾筒和空程滾筒的傳動部分采用行星齒輪機構來完成，具有操作省力、靈活，調整簡便，事故少，維修工作量小的優(yōu)點，同時在吸取成型產品生產和使用經驗的基礎上進一步設計和選用了耙斗裝巖機的臺車、操作機構、剎車機構、耙齒和料槽等部件，繼而最終完成了整臺耙斗裝巖機的設計工作，此外本文還總結了耙斗裝巖機的操作方法以及使用和維護注意事項。
此裝巖機具有效率高、結構簡單，應用范圍廣等特點。不僅可用在平巷裝巖，還可以用在30度以下上山或下山巷道裝巖，以及拐變或90度拐彎的巷道，并且還能進行掘進工序的平行作業(yè)，提高掘進速度，是實現巷道掘進機械化的一種主要機械設備。

ABSTRACT

In order to meet the demand of the scraper loader the big cross section slant hole high-speed driving tunneling speed, then solve the contradiction of the loading speed not to be able to satisfy the tunneling speed, this article in allusion to the characteristic of our country northwest area mine pit, pays attention studies and the transformation loads the machinery a scraper loader. in this paper, take  the scraper loader’s productivity and the steel wire’s traction as the datum, through the massive computations, the inference and the proof, basically completed the scraper loader the reduction gear, the work drum, the spatial regulation drum and so on the majo`ccident little maintain work, at the same time, on the basic of shaping the absorption the product production and experience of using, design and select the rake to fight part and so on charging machine trolley, operating mechanism, brake mechanism, rabble blade and material trough, subsequently, complete the design work of the scraper loader, in addition, the author also summarized operating procedure of the scraper loader and the attentions which must be paid when using and maintaining the scraper loader.
This harrowing bucket loading grab has the characteristics of high efficiency, simple structure and wide applicable range. It can used for loading not only in horizontal way, but also in inclined way with a angle of inclination which is less than 30 to go up or down, in crooked way or 90 crooked way. It can also do the parallel operation of driving procedures, quicken the driving speed, so it is a main machinery equipment to achieve the mechanization of driving way.
