在线路日常养护维修工作中,起拨道作业是非常繁重的。过去,起道作业主要是使用机械传动的齿条压机,机具重量大,操作费力,使用不安全;而拨道作业多使用撬棍,自从铺设了无缝线路和混凝土轨枕以来,由于轨排重量增加,道床阻力加大,拨道很困难,后改用齿条压机斜顶轨顎进行拨道,劳动强度也很大。为了适应养路机械日益发展的需要,近几 Routine maintenance and repair work in the line, from the homework is very heavy. In the past, the main reason for starting the roadwork was the use of rack-driven presses with mechanical transmission. The heavy weight of the machine, the laborious operation and the unsafe use of the equipment resulted in the use of crowbar. Since laying seamless lines and concrete sleepers, Increased row weight, bed road resistance increased, it is very difficult to dial, after the switch to the ramod ram rack jaw press, labor intensity is also great. In order to meet the growing needs of road maintenance machinery, in recent years
