          摘要:

          針對鋼絲繩牽引式雙軌運輸機的牽引鋼絲繩在彎曲起伏軌道上作業時,易出現亂繩和擠繩所帶來的安全性問題,本研究設計了一種無需鋼絲繩的自走式電動雙軌運輸機,該運輸機以三拓GW114165電動機為動力,2個12-LPA-24鉛酸蓄電池作為能源,采用一主動多從動的后驅傳動方式。通過電流測試試驗、平地能耗試驗和打滑性試驗驗證了該運輸機的安全與穩定性,并結合三因素三水平正交試驗法考察驅動輪材料、軌道坡度和裝載質量對運輸機運行速度的影響。結果顯示:在試驗條件下,采用一主動多從動的后驅傳動方式爬坡性能良好,運行比較平穩,但盡量不要在滿載的爬坡狀態下在陡坡處停機,如需停機,可人為輔助啟動,運輸機運行速度為0.241~0.700 m/s,平地運行航程為3 560~6 489.1 m。驅動輪材料、軌道坡度和裝載質量等因素對運輸機運行速度的影響依次是軌道坡度>驅動輪材料>裝載質量,其中坡度對運行速度的Sig值為0.049,小于0.05,影響最為顯著。

          Abstract:

          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 3 560-6 489.1 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.
