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.
