A low floor vertical elevator

Abstract

The present invention proposes a low-floor vertical elevator, which breaks through the structure of traditional vertical elevators and is mainly used in low floors. Cooperate with each other to balance and synchronously drive the four corners of the car, so that the car can realize the lifting action. The invention relies on the screw drive, and the power is large and stable. The ride is more comfortable, and the car is limited by four screw bodies at the same time, so there will be no falling situation, effective protection for passengers, and more safety. Moreover, the central angle corresponding to the opening limiting ring is greater than 180°, which can cover most of the screw body, so that the screw body is effectively limited by the opening limiting ring, which is less likely to shake and runs more stably. The upper end seat and the lower end seat can provide rotation fulcrums for the screw body to make the rotation more stable.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a low-floor vertical elevator. Background technique [0002] More and more urban buildings use vertical elevators. The structure of vertical elevators is known, and generally includes an elevator shaft, a car in the elevator shaft, and a lifting drive device for driving the car to go up and down. The traditional lifting drive device consists of ropes, traction power units and counterweights. With the development of society, aging is also more prominent.

Problems solved by technology

With the development of society, aging is also more prominent. After many years, there will be more and more elderly people in the community. However, elevators were not installed in these communities many years ago, which brought a lot of inconvenience to the elderly.

Therefore, more and more old residential areas are being renovated and new elevators are installed. However, due to the nature of the structure of the elevators, the elevators often have sudden stops or sudden starts. The operation lacks smoothness, and the elevator is a kind of electrical Automation products that combine control and mechanical transmission will naturally have failures such as electrical parts aging, control failure, and mechanical wear and tear failure, which pose a great threat to the personal safety of passengers.
