Description
Technical Field
The invention relates to the technical field of escalators, in particular to a handrail temperature control device for an escalator.
Background
With the progress of science and technology and the continuous improvement of the living standard of people, escalators are increasingly applied to large-scale business and super, railway stations, subways and other large passenger flow fields. As a special device, an escalator not only has strict regulations for manufacturers, but also provides certain riding specifications for passengers, such as: the handrail belt is required to be tightly held when the user rides the bicycle. In actual life, the temperature of the hand strap of the escalator is greatly influenced by seasons, the outdoor escalator is irradiated by sunlight in summer, the temperature of the hand strap rises sharply, and the temperature of the hand strap is too low in winter, so that passengers do not want to hold the hand strap in both situations, and the risk of taking the escalator is increased. Moreover, frequent temperature changes of the handrail can cause embrittlement of the handrail, reduce the service life of the handrail and cause frequent replacement of the handrail.
The handrail temperature adjusting devices disclosed in chinese patent documents CN102530704A and CN205555837U adopt a method of directly heating a handrail belt by an electric heating wire, which cannot cool the handrail belt and is only suitable for heating the handrail belt in winter.
Chinese patent documents CN103130085A and CN205709416U adopt an air conditioning method to adjust the temperature, and the temperature of the handrail belt is adjusted by passing the air heated or cooled by the air conditioning through small holes on the guide rail or by adding a temperature adjusting pipe in the guide rail groove. Although the method can realize the consistency of the overall temperature of the hand strap, the problem of noise generated when air conditioning air passes through the small holes is not ignored.
The chinese patent document CN204111156U also has a noise problem by processing a special hollow handrail belt and then using an air conditioning device to adjust the temperature.
