Background
The escalator is widely applied to large and medium-sized places such as airports, stations, business supermarkets, hospitals and the like at present, and not only serves as a public transport means, but also plays a decorative role in buildings. In the existing escalator, a handrail belt guide rail guides the handrail belt to move according to a designed track, the handrail belt can be ensured to run only by certain tension degree, and the tension degree of the handrail belt can be changed by adjusting the driving force of a driving mechanism for driving the handrail belt to move. However, since the prior art handrail belt and the handrail guide rail exhibit sliding friction, i.e. the handrail belt generates sliding friction with the handrail guide rail while moving, the adjustment of the driving force is very limited, and the lifting height is different and the adjustment of the driving force is also different. Thus, if the tension of the handrail belt is too great, it is liable to break, whereas negative movements such as slipping occur. In addition, the sliding friction is formed between the hand strap and the hand strap guide rail, so that the resistance is large, and the energy consumption is not saved, and the hand strap is not protected.
