Fig. 2 is the birds-eye view of the utility model while being arranged on equipment.
Fig. 3 is that A-A in Fig. 1 is to cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.
Refer to Fig. 1 to Fig. 3, the actuating device of the utility model escalator or moving sidewalk lower end handrail axle, comprise the step chains tension shaft 1 that can move forward and backward along handrail 12 service directions, handrail 12, for driving the friction wheel 4 of handrail 12, for the handrail axle 3 that drives friction wheel 4 to rotate, be installed on the drive sprocket 11 on described step chains tension shaft 1, the handrail axle tensioner bracing or strutting arrangement 7 of driven sprocket 71 is installed, be arranged on the handrail driving chain wheel 31 on handrail axle 3, connect drive sprocket 11, the handrail driving chain 10 of handrail driving chain wheel 31 and driven sprocket 71, handrail driving chain 10 is pressed on to fixed chain wheels assembly 5 and the tensioner chain wheel assembly 2 on handrail driving chain wheel 31.Wherein, step chains tension shaft 1 is arranged on tensioner dolly, and tensioner dolly can be arranged on the metallic framework 100 of escalator or moving sidewalk movably forward and backward.
Wherein, handrail axle tensioner bracing or strutting arrangement 7 can be arranged on the side away from step chains tension shaft 1 movably forward and backward along handrail 12 service directions, handrail driving chain wheel 31 is between drive sprocket 11 and driven sprocket 71, fixed chain wheels assembly 5 has fixed chain wheels 51 and the fixed support 52 that can move up and down adjusting, tensioner chain wheel assembly 2 have can up-and-down movement tensioner sprocket wheel 21, make tensioner sprocket wheel 21 compress tensioner part 22 and the fixed support 23 of handrail driving chain 10 downwards.Tensioner part 22 can be for having the tensioner depression bar of spring, and under the elastic reaction of spring, tensioner sprocket wheel 21, all the time by handrail driving chain tensioner, guarantees that handrail axle 3 is stably driven by handrail driving chain 10.Can regulate tensioner handrail driving chain 10 by the fixed chain wheels 51 of the tensioner sprocket wheel 21 of up-down adjustment tensioner chain wheel assembly 2 and fixed chain wheels assembly 5.
