Description

This application was filed with the China Patent Office on May 10, 2019, claiming the priority of the Chinese patent application with the application number 201910389644.9 and the invention name "Forced Driven Handrail Belt Device". , All the contents of which are incorporated in this application.

The present invention relates to the technical field of escalators or moving walkways, and specifically to forced drive handrail belt devices.

With the rapid development of society, escalators and moving walkway equipment have become indispensable transportation tools for business centers and transportation hubs in the city, especially due to the frequent occurrence of related accidents in the last few years. It is often the focus of society.

Currently, escalator handrail belts are generally driven by friction wheels, and the contact surface of the handrail belt with the drive is flat (the handrail belt is a C-shaped handrail belt) or V-shaped flat (the handrail belt is V-shaped). (It is a handrail belt), and it is a fatal defect that the synchronization and stability of the drive cannot be guaranteed with reference to FIGS. 1 and 2. Since the friction drive is affected by factors such as the coefficient of friction, positive pressure and tension of the handrail belt, the stability of transmission is inferior, especially as the external temperature, humidity, tension of the handrail belt and wear conditions change. , It greatly affects the stability of transmission, and there are many situations such as driving blocking and slipping. That is, the operation of the handrail belt is not synchronized with the operation of the tread plate of the tread.

Based on the riding principle of escalators and moving walkways, if the operation of the handrail belt is not synchronized with the operation of the treads of the treads, passengers may not be able to stand firmly and may fall and pose an even more fatal danger. Yes, in view of this, each state, district or coalition has a deviation range (0 to + 2%) of the operating speed of the handrail belt with respect to the operating speed of the treads of the treads in the safety regulations for the installation and manufacturing of escalators and moving walkways. Clearly stipulates, and stipulates that a handrail belt speed detection control device must be installed for escalators and moving walkways. When it is detected that the deviation between the operating speed of the handrail belt and the operating speed of the tread of the step exceeds a predetermined range, the operation of the escalator and the moving walkway is stopped. Inspection and adjustment of the tension of the handrail belt, handrail belt drive, and handrail belt is an important part of the maintenance of escalators and moving walkways, if the handrail belt or drive is heavily worn or improperly adjusted. , Escalators and moving walkways are prone to breakdowns or safety accidents.

With respect to the above problem, in order to guarantee the synchronous operation of the handrail belt and the tread plate of the step, it is necessary to further optimize the configuration with respect to the conventional handrail belt.
