一、塞带制动装置的研究1.制动器的简单叙述皮带运输机向上运输时必须装有制动装置。它是为了当运输机不正常工作时,(如运输中突然停电)防止皮带受货载的重量分力牵引逆转运行而设的。逆转是很不好的现象。它不但增加了清扫巷道的工作,同时也使得井下空气中煤尘大量的飞扬,后者对有煤尘爆炸危险的矿井是绝不允许的。 First, the study of the stopper with a brake 1. A brief description of the brake Belt conveyor must be equipped with a brake when transported upward. It is designed to prevent the belt from being driven by the weight component of the load when it is not working properly (eg a sudden blackout in transit). Reversal is a very bad phenomenon. It not only increases the work of cleaning the roadway, but also makes a large amount of coal dust in the air downhole, which is not allowed for mines with the danger of coal dust explosion.
