Embodiment Construction

[0021] The present invention is described in detail below in conjunction with embodiment, present embodiment implements under the premise of technical scheme of the present invention, has provided detailed implementation, but protection scope of the present invention is not limited to following embodiment.

[0022] Please refer to figure 1 , the traditional escalator handrail pressing device adopts multi-ribbed belt pressing technology. Since the material of the multi-ribbed belt is rubber, when the escalator handrail needs a large driving force, the rubber is prone to heat and aging, which is likely to cause safety problems. At the same time, Rubber materials depend on imports and are expensive.

[0023] Please refer to figure 2 According to a specific embodiment provided by the present invention, an escalator with a handrail pressing device, the handrail pressing device includes: a pressing chain, which is closely attached to one side of the handrail of an escalator, and i...

Abstract

The invention discloses an automatic staircase with an armrest belt pressing device. The automatic staircase with the armrest belt pressing device comprises an armrest belt pressing device, a belt pressing chain, a plurality of connecting pieces and elastic pieces, wherein the belt pressing chain is tightly fit to one side of the armrest of the automatic staircase for pressing the armrest of the automatic staircase to increase the driving force; the connecting pieces are fixedly connected to a truss of the automatic staircase; two ends of the belt pressing chain are in sliding connection to the connecting pieces; and the elastic pieces are arranged on the connecting pieces for tensioning the belt pressing chain. The automatic staircase with the armrest belt pressing device has the beneficial effects of simple structure, low cost, reliability, durability in use and strong driving force.

Description

[0001] technical field [0002] The invention relates to an escalator, in particular to a handrail pressing belt device of the escalator. [0003] Background technique [0004] In the escalator, in order to solve the danger caused by the inconsistency between the speed of the handrail and the ladder road due to the inability of the driving wheel to completely transmit the power to the untensioned handrail, it is necessary to install a handrail pressure belt device in the escalator, so that the handrail Close to the driving wheel, so as to achieve the purpose of increasing the driving force. [0005] The belt pressing device widely used in the escalator industry is such as figure 1 The traditional escalator handrail belt pressing device shown in the figure adopts multi-ribbed belt compression technology as its main compression structure. Since the material of the multi-ribbed belt is rubber, when the escalator handrail needs a large driving force, the tension spring is more...
