矿山使用电机车运输,轨道需要经常维护,以确保机车安全行驶。通常在处理轨道下沉和更换枕木时,需2～3人用钢钎将钢轨撬起才能工作。为减轻劳动强度,提高工效,我们根据螺旋原理制成了螺旋抬轨器(见图)。它结构简单,重量轻(22.5公斤)、体积小、制造容易、使用方便。在我矿轨道维修中使用效果良好,我们经长时间的现场使用证明,可 The use of electric locomotive mines transport, orbit needs regular maintenance, to ensure the safe running of locomotives. Usually in dealing with the sinking and replacement of sleepers track, take 2 to 3 people with a steel rod to pry the rail to work. In order to reduce the labor intensity and improve the work efficiency, we made a spiral rail rail according to the principle of helix (see picture). Its structure is simple, light weight (22.5 kg), small size, easy to manufacture, easy to use. In my mine track maintenance with good results, we have a long time on-site use that
