一、前言刨煤机,作为采煤机械的一个品种,在国外一些国家发展较快,在我国也有定型产品。但是它的终端停车装置却是个难题,到目前为止还没有一个成熟可靠的产品,就是在国外技术比较先进的国家,刨煤机到工作面两端的停车还是要用两个人来完成。即使人工停车,也并不是万无一失,一旦失误就撞坏机头,这些事情也常有发生。研究一种行程开关,装在工作面两端,机头过来就自动停车,这是最理想的。但事情并非像想象的那么简单,原因还在于刨煤机的特殊性。 First, the foreword Plow, as a species of coal mining machinery, developed rapidly in some foreign countries, there are stereotypes in our country. However, its terminal parking device is a difficult problem. So far there is no mature and reliable product, that is, in countries with advanced technology abroad, the plow to the parking surface at both ends of the work surface should be completed by two people. Even manual parking, it is not foolproof, once the error crashed the nose, these things often occur. Study of a trip switch, installed at both ends of the face, head over to automatically stop, this is the best. But things are not as simple as you think, because of the special nature of plows.
