一关于台车牵引新建厂砂型干燥炉一般均设有专门的台车牵引机构,国外设计厂如洛阳矿山机器厂、兰州石油机器厂等大都如此。由于干燥炉的周期较长(8～36小时),牵引机构一天最多也不过使用一、二次,每次时间仅仅只有几分钟。显然,这是很不经济的。旧厂现有台车系利用行车牵引,设备简单、经济,但存在着一定缺点:1.台车在炉中有时因某种原因(轨道堵塞、车轴胀死等)而拖不动,结果常常使钢绳的应力突然加大以致
A sand screed drying machine for traction trucks is generally equipped with a special traction mechanism for trolleys. Foreign design plants such as Luoyang Mining Machinery Factory and Lanzhou Petroleum Machinery Plant are generally the same. Since the cycle of the drying furnace is long (8 to 36 hours), the traction mechanism can only use one or two times at a time, and only a few minutes at a time. Obviously, this is very uneconomical. The existing trolleys of the old factory are equipped with traction and the equipment is simple and economical. However, there are certain disadvantages: 1. The trolley sometimes fails to move due to certain reasons (rail jam, axle collapse, etc.), and the result is often Suddenly increase the stress of the rope
