Description

Technical Field

[0001] This invention patent belongs to the field of engineering technology, specifically relating to a method for lifting a multi-spoke, multi-carriage, traction-free elevator in the same shaft. Background Technology

[0002] Currently, the method for lifting people or goods using elevators is the "one shaft, one car" method, where one car is installed in each elevator shaft, and the elevator travels vertically with only one car at a time. This method has the following drawbacks: First, there is insufficient capacity during peak hours, resulting in long waiting times for passengers, while fewer passengers ride during off-peak hours, leading to waste; second, if the car or lifting system malfunctions, the elevator stops, and the elevator shaft becomes idle; third, the lifting traction mainly relies on steel wire ropes, which wear out quickly, posing safety risks. Therefore, it is necessary to invent a lifting method to solve the above problems. Summary of the Invention

[0003] This invention provides a method for lifting multi-spoke, multi-carriage, traction-free elevators in a single shaft, in order to solve the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a method for lifting a multi-spoke, multi-car, traction-free elevator in a single shaft, wherein an elevator shaft is divided into three spokes: an upward spoke, a downward spoke, and a stopping spoke. When the car on the upward or downward spoke reaches the stopping floor, it rotates 120 degrees. o The system rotates horizontally to the designated stopping point for passenger and freight transport. Multiple cars can be installed in each stopping point. Each car within the three stopping points operates independently along its respective guide rail. If a car malfunctions, it can be lifted to the top floor or a specific floor for repair, while the other cars continue to operate normally. If a problem occurs in the passageway of one stopping point, the other two stopping points can continue operating normally. Each stopping point and each car has an independent power drive system, with each car controlled by a three-axis drive and three-point braking system.

[0005] The aforementioned branching divides the elevator shaft into three branches: the upward branch, the downward branch, and the stopping branch. Each branch can accommodate one or more elevator cars.

[0006] The guide rails consist of a three-sided toothed guide rail installed in the center of the shaft as the central drive guide rail for the car, and six single-sided toothed guide rails installed on the inner wall of the shaft as side drive guide rails for the car. Each car has three guide rails: a central guide rail, a left side rail, and a right side rail. The side rails are fixed to the inner wall of the elevator shaft, and the central guide rail is connected and fixed to the side rails and the inner wall of the elevator shaft every 3 meters using three-way lateral supports.

[0007] The drive system features a central drive gear installed on the top of each car near the central guide rail, and left and right drive gears installed on the top of the car near the left and right rails, respectively. Each car uses a three-axis motor for drive and braking, eliminating the need for traditional elevator traction cables and traction machines.

[0008] The power source is a battery installed at the top or bottom of each car, which eliminates the need for traditional elevator power cables.

[0009] The elevator car can be installed in one or more carriages depending on the situation. For example, in a 30-story building, three carriages can be installed in each of the upward and downward carriages, and six carriages can be installed in one elevator shaft.

[0010] The operation, in the upward mode: the car stops to pick up passengers or goods - the car rotates clockwise 120 degrees around the central guide rail. o To the upward-moving spoke - the car ascends - arriving at the destination floor - the car rotates counterclockwise 120 degrees around the central guide rail. o To stop - passengers or cargo unload - the car rotates clockwise 120 degrees around the central guide rail. o Upward movement: Passengers or cargo are loaded onto the car at the next stop – the car rotates counter-clockwise 120 degrees around the central guide rail. o Towards the downward-descending axis - the car descends - arriving at the destination floor - the car rotates clockwise 120 degrees around the central guide rail. o To stop - passengers or cargo unload - the car rotates counterclockwise around the central guide rail 120 degrees. o It will continue to operate in a downward radial pattern.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a method for lifting multi-spoke, multi-car elevators without traction in the same shaft, which effectively solves the problems of insufficient capacity during peak hours and waste during off-peak hours. After the elevator shaft of the same area is divided into spokes, the area of ​​each car is reduced to 1 / 3. If 3 cars are installed in each of the upward and downward spokes, the peak capacity is increased by 3×1 / 3×2×3=6 times.

[0012] 2. The present invention provides a method for lifting a multi-spoke, multi-car elevator without traction in the same shaft, which effectively solves the problems of elevator malfunction and the entire elevator shaft stopping. Each car in the three spokes adopts an independent power drive system and operates independently. If a car malfunctions, it can be lifted to the top floor or a specific floor for repair, while the other cars can operate normally. If a problem occurs in the passage of a certain spoke, the other two spokes can operate normally, thus avoiding the problem of the entire elevator shaft stopping.

[0013] 3. The present invention provides a lifting method for a multi-spoke, multi-car traction-free elevator in the same shaft, which effectively solves the problem of car operation safety. It adopts an independent power drive mode for each spoke and each car, and a single car is controlled by a three-axis drive and a three-point braking mode, thereby improving the car operation safety.
