摘　　要：针对输送机的水平输送和倾斜输送,在头部拉紧条件下,探讨了输送机启动时固定式、自动式、重锤式拉紧三种装置动张力对张紧力的影响,推导了输送带的弹性伸长量和启动时输送带最小张力的变化值。最后,与尾部拉紧的情况进行了对比,得出了结论。Contraposing the horizontal and inclined conveying, this paper discusses the effects of the belt tension on the dynamic tension of fixed tension device, automatic tension device and weighted tension device when starting a belt conveyor. The elastic elongation magnitude and the change value of minimum tension of belt when starting are deduced. Finally, it comes to a conclusion through comparing with tension way in the tail of the belt conveyor.
