Traction drive multi-car shared multi-hoistway circular operation elevator

Abstract

The invention discloses a traction drive multi-car shared multi-hoistway circular operation elevator. The elevator is composed of a multi-hoistway structure, multiple independent operation cars, multi-layer stacked traction rope guide wheel translation driving parts, multi-layer stacked car rope hitch firmware translation driving parts, multi-layer stacked traction machines and multiple counterweight rope hitch firmwares, wherein the multi-hoistway structure comprises four vertical operation hoistways, one upper translation hoistway, one lower translation hoistway, multiple independent counterweight vertical up-and-down movement spaces, a multi-layer guide wheel and car rope hitch firmware translation driving part supporting frame and a multi-layer traction machine and counterweight rope hitch firmware supporting frame. According to the elevator, all the cars are driven by the traction machines and translation driving devices to do vertical and upper and lower translation operation, guide wheels of the translation driving parts and traction ropes on the rope hitch firmwares are driven to do horizontal and longitudinal translation through horizontal translation driving devices and longitudinal translation driving devices, so that multiple cars can share the hoistways for circular operation, the elevator is a multi-hoistway circular operation elevator capable of integrating existing technologies, and the hoistway utilization rate can be increased.

Description

Technical field: [0001] The invention belongs to the technical field of elevators, and in particular relates to a traction-driven multi-car shared multi-well circulation elevator. Background technique: [0002] With the popularity of high-rise buildings, elevators have become an indispensable vertical transportation equipment in buildings. After nearly a hundred years of development, elevators have made great progress in safety, reliability, and energy saving, and their driving methods have gradually formed. Traction drive is the dominant drive mode. The traction drive mode is that one end of the traction rope is connected to the car, and the other end is connected to the counterweight. The gravity of the car and the counterweight device makes the traction wire rope compressed in the traction wheel groove Friction, in this way, the rotation of the motor drives the traction wheel to rotate, drives the wire rope, drags the car and the counterweight for relative motion, that is...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a traction-driven multi-car shared multi-shaft circulation elevator, the elevator is independently circulated by multiple traction-driven cars in a multi-well closed space It not only retains the existing technologies and existing advantages of traction drive elevators such as safety, energy saving, and long travel, but also overcomes the shortcomings of low utilization efficiency of the single-car elevator shaft. The elevator is installed between adjacent cars. When the safe and exclusive area is fixed, the longer the hoistway, the more cars can be operated, which effectively improves the utilization efficiency of the hoistway. By increasing the number of cars running in the closed space of modern skyscrapers with super long multi-shafts, it can be improved. The transmission efficiency of the elevator achieves the purpose of effectively reducing the number of elevator shafts and the occupied area on the basis of ensuring the number of running cars in super high buildings. The heavy and its traction sheave and other moving parts can operate independently, and run smoothly without interference points. It is a circulating elevator that can integrate existing technologies with low cost and high shaft utilization.
