Problems solved by technology

In real life, the temperature of the escalator handrail is greatly affected by the season. In summer, the outdoor escalator is exposed to sunlight, and the temperature of the handrail rises sharply, while in winter, the temperature of the handrail is too low. Willing to hold on to the handrails, which increases the risk of taking an elevator
Furthermore, the frequent temperature changes of the handrails will cause the handrails to become brittle, reduce the service life of the handrails, and lead to frequent replacement of the handrails
[0003] The handrail temperature adjustment device disclosed in Chinese patent documents CN102530704A and CN205555837U adopts the method of directly heating the handrail with electric heating wire. This method cannot cool the handrail and is only suitable for heating the handrail in winter.
Although this method can achieve the consistency of the global temperature of the handrail, the noise problem caused by the air-conditioning wind passing through the small hole cannot be ignored
[0005] Chinese patent document CN204111156U processes a special hollow handrail and then uses an air conditioner to adjust the temperature. This method also has noise problems

Abstract

The invention discloses a handrail temperature control device for an escalator. The handrail temperature control device comprises a heat conduction pipe and a temperature adjusting device; the heat conduction pipe is laid along a running path of a handrail belt of the escalator; the heat conduction pipe is connected to the temperature adjusting device to form a closed loop; and the temperature adjusting device is used for heating or cooling a liquid thermal medium, then feeding the liquid thermal medium into the heat conduction pipe and enabling the liquid thermal medium to circularly flow in the heat conduction pipe. According to the handrail temperature control device for the escalator, the handrail belt can be heated / cooled and is in a proper temperature range, noise is low, and the installation is convenient.

Description

technical field [0001] The invention relates to the technical field of escalators, in particular to a handrail temperature control device for an escalator. Background technique [0002] With the advancement of science and technology and the continuous improvement of people's living standards, escalators are increasingly used in places with large passenger flows such as large supermarkets, railway stations and subways. As a special equipment, the escalator not only has strict regulations on the manufacturer, but also puts forward certain riding specifications for passengers, such as: hold the handrails tightly when riding, etc. In real life, the temperature of the escalator handrail is greatly affected by the season. In summer, the outdoor escalator is exposed to sunlight, and the temperature of the handrail rises sharply, while in winter, the temperature of the handrail is too low. Willing to hold on to the handrails, thus increasing the risk of taking the elevator. Furthe...
