The future development of elevators

Elevators are an important means of transportation in mid- to high-rise buildings. As an integral part of architecture, the innovation and application of elevators are closely related to the development of architecture. With the rapid development of technology, Internet of Things, and artificial intelligence, elevator technology is also developing rapidly. The application of new materials, faster response, and higher configuration have prompted people to have high requirements and expectations for elevators. In what direction will elevator technology develop in the future?

 

Ultra-high-speed elevator technology suitable for high-rise and super-high-rise buildings

At present, the construction industry has been able to build buildings over 1000m or even higher, but the ultra-high-speed elevator technology responsible for vertical transportation has become a development bottleneck. Ultra-high-speed elevators involve research on ultra-large-capacity motors, traction suspension systems, high-precision guide rails, high-performance microprocessing, shock absorption and noise reduction technology, intelligent shock-absorbing roller guide shoes, and car air pressure relief, and will become the basis for the development of ultra-high-speed elevators. key technologies.

 

 

Multi-car technology

In traditional elevators with shafts, only one car runs in each shaft. For high-rise and super-high-rise buildings, there are problems such as low transportation efficiency, long waiting time, and low hoistway space utilization. Multi-car elevators include double-deck elevators, double-car elevators, circular elevators, bifurcated circular elevators and shuttle elevators, etc.

 

Cableless elevator technology based on linear motor and magnetic levitation technology

Traditional traction elevators are usually only used for vertical transportation due to limitations of traction ropes and cables. Cableless elevators based on linear motors and magnetic levitation technology remove the steel cables, traction machines, counterweights, and other components of traditional elevators. Complex mechanical equipment such as speed limiters, guide wheels, and counterweight wheels can realize the arrangement of multiple cars running in the hoistway, and even break through the traditional vertical operation. They can run criss-cross to the predetermined position of the building, which can greatly Improve the efficiency of elevators and shafts.

 

New material application technology in suspended traction media

For high-rise and super-high-rise buildings, traditional traction wire ropes face problems of their own weight and tensile strength. The use of composite steel belts and plastic-coated steel wire ropes can reduce the diameter of the traction pulley and guide pulley, thereby reducing the size of the traction pulley, making the overall elevator layout more compact and saving space. The application of non-metallic suspension ropes (belts) and non-metallic traction sheaves greatly increases the friction coefficient between the rope and the sheave, reduces the diameter of the traction sheave, reduces the torque requirements of the elevator traction machine, and can reduce the number of traction machines. The volume reduces the material consumption of traction machine manufacturing. In addition, non-metallic materials have good shock-absorbing properties, which can effectively reduce the transmission of vibration from the traction machine to the car, as well as the noise when the traction rope and traction sheave are running. On the premise of ensuring safety, the development and application of new materials for suspension traction media will further increase the service life of the traction wheels and reduce system costs.

 

Elevator Internet of Things Technology

As a typical representative of the new generation of information technology, Internet of Things technology is a deep integration of Internet technology, sensor technology, and radio frequency identification technology, and has been vigorously developed and widely used. Elevator Internet of Things is the application of Internet of Things technology in the elevator industry. It integrates elevator control technology, information sensing technology, network communication technology, computer application technology, etc., and uses Internet of Things technology to integrate elevator monitoring, maintenance management, usage management, and safety. Early warning, emergency response, humanized services and even inspection modes are organically integrated to realize information and data exchange between elevators and users, property management units, maintenance units, manufacturing units, inspection agencies and supervisory agencies.
