[0004] On the escalator, the handrail belt is wrapped on the handrail guide rail, and the handrail belt has a certain degree of tension. The handrail belt is guided to run up or down by the handrail guide rail. At this time, there is sliding friction between the handrail belt and the handrail guide rail. The handrail belt has a large pressing force on the handrail guide rail at the upper arc section, so the handrail belt in the upper arc section receives a large frictional resistance during operation, resulting in a high requirement for the driving force of the handrail belt, and this Will reduce the service life and running comfort of the handrail

Embodiment Construction
[0017] The structure of the present invention will be further described below in conjunction with the accompanying drawings.
[0018] see Figure 1-2 As shown, the structure of the upper arc section of the handrail of the escalator includes a flexible handrail 3, an arc guide rail 2 capable of guiding the movement of the handrail 3, and an arc chain plate 4. The arc guide rail 2 includes an arc bottom 5, a The arc-shaped side parts 6 extending upward from the left and right sides of the shaped bottom 5 and the lugs 9 protruding outward from the arc-shaped side parts 6 on both sides are formed between the arc-shaped bottom 5 and the arc-shaped side parts 6 on both sides. There is a receiving space 10 with an upward opening 20, and the handrail 3 includes a base 14 arranged on the curved guide rail 2 to cover the opening 20, and a side portion 15 bent downwards from the left and right sides of the base 14 to wrap around the lug 9, The side part 12 of the handrail 3 encloses the...

The invention discloses an upper arc-section structure of an escalator handrail belt, wherein an arc-shaped chain plate which is arranged in an arc-shaped guide rail and is distributed along the arc length direction of a guide rail comprises an arc-shaped bottom plate and a plurality of pairs of side plates extending upwards from the left side and the right side of the arc-shaped bottom plate; the plurality of pairs of side plates are arranged at intervals along the arc length direction of the arc-shaped bottom plate; rolling pieces are arranged between the paired side plates; a base part of the handrail belt is exposed on the inner surface in an opening of a containing space to be contacted with the rolling pieces in a rolling manner; the resistance generated by rolling friction is less;and in fact, the plurality of rolling pieces support the handrail belt, at the moment, gaps exist between the top surfaces of convex lugs on the arc-shaped guide rail and the inner surface of the handrail belt, so that the handrail belt and the top surfaces of the convex lugs are not contacted basically or the contacting area is reduced. Therefore, when the handrail belt runs, the friction resistance generated between the handrail belt and the rolling pieces or the convex lugs is less, and due to reduction of the friction resistance of the upper arc section, the requirement on the driving force of the handrail belt is reduced, the service life of the handrail belt is prolonged and the running comfort of the handrail belt is improved.
Description
[0001] technical field [0002] The invention relates to the structure of the upper arc segment of the handrail of an escalator. [0003] Background technique [0004] On the escalator, the handrail belt is wrapped on the handrail guide rail, and the handrail belt has a certain degree of tension. The handrail belt is guided to run upward or downward through the handrail guide rail. At this time, there is sliding friction between the handrail belt and the handrail guide rail. The handrail belt has a relatively large pressing force on the handrail guide rail at the upper arc section, so the friction resistance of the handrail belt in the upper arc section is very large during operation, resulting in a high requirement for the driving force of the handrail belt, and this This reduces the service life and running comfort of the handrail. [0005] Contents of the invention [0006] The object of the present invention is to provide a structure in which an arc-shaped chain pla...
