我矿由1964年开始在斜巷轨道运输线路使用防跑车安全设施,经过多次反复试验改进,制做出这种速动挡车器.十多年来,我们坚持使用,效果良好,予防了多次跑车事故,做到了斜巷运转安全生产。我矿轨道运转(上、下山)坡度一般在6～12度。一吨矿车串车提升。由于矿车车架断裂、掉轮、链环断裂、插锁窜出、断绳等原因,造成跑车。为了防止跑车造成重大损失,就在斜巷内约隔100～150米
Since 1964, mine started to use anti-sports safety equipment in the inclined lane rail transportation line, and after repeated trial and error tests, made such speed stop gear. For more than ten years, we insisted on using it and the effect was good. Second sports car accident, to achieve the safe operation of inclined road operation. Mine mine track (up and down the mountain) the slope is generally 6 to 12 degrees. A ton of mine car series to enhance. As a result of the broken frame car, off the wheel, broken link, plug lock sprang, broken rope and other reasons, resulting in sports car. In order to prevent the sports car caused a significant loss, about in the inclined lane about 100 to 150 meters
