The invention discloses a spiral escalator formed by a handrail belt driving device, which comprises steps, a driving main machine, a step driving main shaft, a driving chain connected with the step driving main shaft and the driving main machine, a handrail shaft used for driving a handrail belt to move, and at least one transition shaft arranged between the step driving main shaft and the handrail shaft, the steps are arranged in a fan shape, and the steps arranged in the fan shape are meshed with one another. The transition shaft at least comprises an outer side transition shaft close to the outer side hand strap and an inner side transition shaft close to the inner side hand strap; the step driving main shaft and the inner side transition shaft rotate synchronously, and the handrail shaft and the outer side transition shaft rotate synchronously. The steps, the outer side hand strap and the inner side hand strap are started and stopped at the same time; the length of the outer side handrail belt is larger than that of the inner side handrail belt. According to the spiral escalator, the special requirements that the hand strap needs to be bent laterally, the angular velocity of the two sides is the same, and the linear velocity of the two sides is different can be met.
本发明公开了一种由扶手带驱动装置构成的螺旋式自动扶梯,包括梯级、驱动主机、梯级驱动主轴、连接所述梯级驱动主轴和驱动主机的驱动链条、用于驱动扶手带运动的扶手轴、设置在所述梯级驱动主轴与扶手轴之间的至少一个过渡轴,所述梯级为扇形设置,扇形设置的梯级之间相互噬合;所述过渡轴至少包括靠近外侧扶手带的外侧过渡轴以及靠近内侧扶手带的内侧过渡轴;所述梯级驱动主轴与所述内侧过渡轴同步转动,所述扶手轴与外侧过渡轴之间同步转动;所述梯级和外侧扶手带、内侧扶手带同时启停步动;所述外侧扶手带的长度大于内侧扶手带的长度。本发明的螺旋式自动扶梯,能够达到扶手带既要侧向弯曲又要两侧角速度相同、线速度不同的特殊要求。
