Technical scheme of the present invention is: a kind of rounded nose handrail actuating device, be installed in the round end truss in escalator or automatic humanoid road, be used to drive handrail, it includes revolution sprocket shaft, handrail axle drive shaft, messenger chain wheels, handrail power wheel, described revolution sprocket shaft, handrail axle drive shaft are rotatably installed in the truss, the handrail axle drive shaft is parallel with the revolution sprocket shaft and toward each other at interval, is connected by the messenger chain wheels between revolution sprocket shaft and the handrail axle drive shaft; The handrail axle drive shaft is provided with the handrail power wheel, and described handrail power wheel drives handrail by the speed motion of setting.
Described messenger chain wheels comprise handrail drive sprocket, handrail driven sprocket, driving chain, the handrail drive sprocket is arranged on the revolution sprocket shaft, the handrail driven sprocket is arranged on the handrail axle drive shaft, is wound with driving chain on described handrail drive sprocket, the handrail driven sprocket.
Described messenger chain wheels also comprise the auxiliary press nips that is used to increase driving chain cornerite on the handrail driven sprocket.
Described auxiliary press nips comprises auxiliary pinch roller and the auxiliary pinch roller that is separately positioned on handrail driven sprocket both sides.
Described revolution sprocket shaft is provided with the revolution sprocket wheel, and revolution sprocket wheel outside is arranged with the step chain that is used to drag escalator or moving sidewalk step or pedal.
Described revolution sprocket shaft moves to realize that the revolution sprocket wheel interconnects the slack-free step chain tightening device of step chain with making the revolution sprocket shaft.
Described messenger chain wheels also comprise idler sprocket.
Described idler sprocket is installed on the tightening device, and described tightening device connects the revolution sprocket shaft by connecting rod, and idler sprocket keeps same moved further with the revolution sprocket shaft.
Described handrail axle drive shaft is rotating to be installed on the supporting seat, and supporting seat is installed on the truss.
Because technique scheme utilization, the present invention compared with prior art has following advantage: rounded nose handrail actuating device of the present invention, be installed in escalator or moving sidewalk round end (lower end) truss, directly obtain power from the revolution sprocket shaft, to cooperate the original handrail driving device of drive end (upper end), do not need to increase the power-handling capability increase at double that makes handrail under the situation of truss depth, can satisfy the escalator of big hoisting depth or the demand that the moving sidewalk handrail drives.Make the Tension Distribution of handrail also more reasonable simultaneously.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a birds-eye view of the present invention.
