研究了电动铲运机工作过程中电缆张力的变化,提出了电缆动态张力的计算公式,根据现场实测的结果,提出了考虑路面不平度和铲运机振动时的修正系数,并计算了卷、放缆溢流阀开启压力的比值和电缆的最大冲击张力。
The paper studies the change of cable tension during the operation of electric scraper and puts forward the calculation formula of the dynamic tension of the cable. According to the field measurement results, the correction coefficient considering the unevenness of the road surface and the vibration of the scraper is proposed, The ratio of the cable relief valve opening pressure and the maximum impact tension of the cable.
