翻矸工作是竖井掘进过程中的一个重要环节。当前,我国矿山推广使用了链球式自动翻矸。这种翻矸方式结构简单,工作比较可靠,节省人力,受到现场欢迎。但这种翻矸方式由于运行不平稳,有冲击力,因而链子常断;又由于链子长,翻矸装置占用高度较大,为保证规定的“过卷高度”,现有Ⅲ型井架不能满足要求。产生冲击力的原因是:弧板是单层的,吊桶需滑动一定距离后,链球才被卡住。这时吊桶有一定速度,链球就受到冲击力。为了解 Dumping work is an important part of shaft excavation process. At present, China’s mine to promote the use of chain-type automatic turning waste. This method of turning waste structure is simple, more reliable work, save manpower, welcomed by the scene. However, due to the unstable operation of the plowing operation, the chain is often broken. Since the length of the chain is long and the height of the palletizing device occupies a relatively large height, the existing type Ⅲ derrick can not satisfy the requirement of “over-winding height” Claim. The reason for the impact is: the arc is a single layer, buckets to be sliding a certain distance, the hammer only be stuck. At this time buckets have a certain speed, the hammer on the impact. To understand
