Abstract:Aiming at the safety problem caused by random rope and extruded rope when the rope is used on the curved and undulating track, a kind of self-propelled electric double-track conveyor without wire rope is designed. Conveyor is mainly composed of electric driving system and transmission system, light quality, the ground target load and the maximum slope load design value of 75 kg, 175 kg, 75 kg, the maximum slope gradient is 30 °.The mechanical model of the conveyor was analyzed, and the motor and battery parameters were obtained. The selected driving motor model was Santuo GW114165.Through the finite element analysis of rubber wheel, it is shown that both the driving wheel and the supporting wheel meet the design requirements. The current test shows that under the conditions of different loads and different slopes, the variation range of power supply current and motor current of the conveyor is 2.61~ 20.12a and 1.305~ 10.06a respectively. The selected motors and batteries meet the design requirements, and the running speed of the conveyor is 0.241~0.7m/s. The flat land energy consumption test shows that the same load has a small variance, indicating that the energy consumption of the transport plane is relatively stable under the same working condition. The energy consumption is maintained at 1.58-2.88w h under different loadings. According to the battery pack capacity of 576W?h, the range of the flat land of the transport plane is calculated to be between 3560m and 6489.1m.The skidding test shows that it is best not to stop the machine at the steep slope under full load climbing state. If the machine needs to stop, it can be started manually. The orthogonal test shows that the driving wheel material, the rail slope and the loading quality have different influences on the operation speed of the conveyor. The influences of each factor on the operation speed are B>A>C, and the Sig value of the slope on the operation speed is 0.049, less than 0.05, which has the most significant influence. Therefore, in order to improve the operation speed of the conveyor, the rail slope can be taken as the entry point to reduce the slope as far as possible, so as to improve the operation speed of the conveyor. Therefore, this study can better solve the safety problems caused by random rope and rope extrusion when the traction steel wire rope of the wire rope traction type double-rail transport plane works on the curved and undulating track, and provide a reference for the follow-up development of the self-propelled double-rail transport plane in the mountainous area.
