摘　　要：针对钢丝绳牵引式双轨运输机的牵引钢丝绳在弯曲起伏轨道上作业时,易出现乱绳和挤绳所带来的安全性问题,本研究设计了一种无需钢丝绳的自走式电动双轨运输机,该运输机以三拓GW114165电动机为动力,2个12-LPA-24铅酸蓄电池作为能源,采用一主动多从动的后驱传动方式。通过电流测试试验、平地能耗试验和打滑性试验验证了该运输机的安全与稳定性,并结合三因素三水平正交试验法考察驱动轮材料、轨道坡度和装载质量对运输机运行速度的影响。结果显示:在试验条件下,采用一主动多从动的后驱传动方式爬坡性能良好,运行比较平稳,但尽量不要在满载的爬坡状态下在陡坡处停机,如需停机,可人为辅助启动,运输机运行速度为0.241~0.700 m/s,平地运行航程为3560~6489.1 m。驱动轮材料、轨道坡度和装载质量等因素对运输机运行速度的影响依次是轨道坡度>驱动轮材料>装载质量,其中坡度对运行速度的Sig值为0.049,小于0.05,影响最为显著。An electric self-propelled double-track transporter without a wire rope was designed to solve the safety problems caused by messy rope and rope squeezing when the wire rope traction double-track transporter is operating on a curved and undulating track.The transporter is powered by Santuo GW114165 motor using two 12-LPA-24 lead-acid batteries as energy source,and adopts rear drive transmission mode of one-active and multi-slave.The safety and stability of the transporter was verified through tests of current test,level ground energy consumption and skid.The three-factor three-level orthogonal test method was combined to study the effects of materials of driving wheel,track slope and loading quality on the speed of transportation.The results showed that the rear drive transmission mode of one-active and multi-slave has good performance of climbing and relatively stable operation under the test conditions.Stopping at a steep slope under a full-load climbing state should be avoided as possible.If it needs to stop,it can be started manually.The running speed of the transporter is 0.241-0.700 m/s,and the range on flat ground is 3560-6489.1 m.The effects of material of driving wheel,track slope and loading quality on the speed of transportation is in the decreasing order of track slope,material of driving wheel and loading quality.The track slope has the most significant impact on the running speed with a Sig value of 0.049,which is less than 0.05.
