以前使用的装罐推车机,在推车时推爪不进罐,一般推爪距罐笼边缘为40～80mm,其余部分靠矿车自滑到位.当井口操车使用阻拉器以后,要求推车机必须推车进罐到位,并要通过阻拉器的阻爪和推车器的推爪把矿车固定在设计位置.以前国内没有这种长推爪推车机,在标准系列罐笼中,取消罐内阻车器,要求全部配合阻拉器使用以来,各地对这种长推爪推车机的要求更加迫切.我院设计的长推爪推车机是配合3m摇台和阻拉器使用的推车机.推爪长为700mm,推车时推爪进入罐笼375mm,在浙江长广煤炭公司七矿使用一年多,效果很好.现就针对这种推车器的结构特点、动作受力分析、以及设计、制造和维护方面的要求作一简单介绍,供煤炭工程技术人员参考.
Previously used tin loading machine, push the paw does not enter the pot when the cart, the general push claws from the edge of the cage 40 ~ 80mm, the rest of the self-sliding by the tub in place. Push the cart into the tank must be in place, and through the drag stopper and push the claws of the trolley to fix the tub in the design position.Previously there is no such long push paw pusher in the standard series of cage , The elimination of the canister on the tank, requiring all the use of dragging devices, all over the long push claw pusher machine more urgent requirements of our hospital designed long push claw pusher machine is with 3m cradle and resistance Pull the cart machine used. Push the claw length of 700mm, the cart pushed into the cage when the claw 375mm, Changzhi Coal Company in Zhejiang Seven Mine used more than a year, the effect is very good. Now for the structure of this pusher Characteristics, analysis of the force acting on the movement, as well as the design, manufacture and maintenance requirements for a brief introduction for coal engineering and technical personnel for reference.
