A low-speed vertical elevator

Abstract

The invention proposes a low-speed vertical elevator, which is mainly used for low-speed transportation on low floors, has large and stable torque, and is not prone to accidents. The car is driven up and down by four driving screw mechanisms, and each positioning mechanism can limit the driving screw mechanism to realize the stable operation of the driving screw mechanism and drive the car to achieve smooth and stable lifting. Specifically, when a passenger takes the car, the controller controls the motors to drive the threaded columns to rotate synchronously, and uses the external thread of the threaded column to cooperate with the internal thread of the car to balance and synchronously drive the four corners of the car. , so that the lift of the car can be realized. The present invention relies on threaded drive, and the power is large and stable. At the same time, the position is limited, and there will be no falling situation, which effectively protects passengers and is safer.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a low-speed 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. After many years, there will be more and more elderly people in the community.

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.
