Multi-door elevator device with single hoistway and double cars

Abstract

The invention discloses a multi-door elevator device with a single hoistway and double cars. The multi-door elevator device with the single hoistway and the double cars comprises a traction mechanismand two groups of car mechanisms, wherein the traction mechanism comprises a fixed seat and four guide rails connected to the fixed seat; the two groups of car mechanisms are arranged in an up and down opposite manner; each car mechanism comprises a frame-type car frame and a car main body; the car frame comprises a horizontal fixed frame and four stand columns connected to the horizontal fixed frame; and the car main body is located at the inner sides of the four stand columns and are fixedly connected to the four stand columns. The design mode of the elevator device saves energy, increases the load capacity of the elevator, and improves the safety in the elevator running. The layout in such a manner can reduce the occupied area of a machine room and the hoistway, increases the area utilization ratio of a building, improves the operating efficiency of the elevator, and reduces energy consumption. The elevator is relatively stable and comfortable during running, and is relatively safewhen the elevator goes wrong.

Description

technical field [0001] The invention relates to the technical field of elevator devices, in particular to an elevator device with single shaft, double cars and multiple doors. Background technique [0002] With the rapid development of society, the pace of urbanization is getting faster and faster, and the number of high-rise and ultra-high-rise buildings in my country's cities has increased rapidly. As of 2015, there are more than 350 super-high-rise buildings over 200 meters under construction in the world, of which about There are 110 buildings, and there are countless high-rise buildings between 100 meters and 200 meters. The construction of these high-rise buildings has driven the market's strong demand for high-speed and ultra-high-speed elevators. [0003] High-rise and ultra-high-rise buildings have also brought many problems, such as the problem of people entering and leaving the building, the problem of elevator use area and building area, and the problem of serious...

AI Technical Summary

Problems solved by technology

The peak period for internal personnel to use the elevator is morning, noon and evening. At this time, the flow of people is particularly huge, and the floors that enter and exit are mostly fixed floors. long

Application No. 201320045916.X patent application document records a kind of elevator with single shaft and double car. Although this elevator solves the above problems to a certain extent, the elevator has the following disadvantages: the interior area of ​​the elevator car is small, and the car There is only one exit, and the efficiency of the elevator is extremely low when there is a huge flow of people and the time is short during the peak period of elevator use

The double-car elevator operates with a single pair of guide rails. Because the elevator runs fast and there are two cars in the guide rails, there are too many floors between the upper and lower ends of the guide rails, and it is easy to shake during operation, resulting in safety problems during operation.

Moreover, the hoistway of the double-car elevator takes up too much area.
