Car-frame-free elevator driven by traction steel belt

Abstract

The invention discloses a car-frame-free elevator driven by a traction steel belt. The elevator comprises a bearing device, a driving device and a lift car, a bearing wheel is arranged at the top of the bearing device, the bearing wheel is sleeved with a traction steel belt, one end of the traction steel belt is connected with a first steel belt terminating device, and the other end of the traction steel belt sequentially penetrates through the driving device and the lift car and is connected with a second steel belt terminating device; a car roof beam is arranged at the top of the lift car, abase is arranged at the bottom of the lift car, the base is connected with the periphery of the car roof beam through vertical plates, the lower end of the base is connected with an installation frame, and car bottom wheels matched with the traction steel belt are arranged at the two ends of the installation frame. The first steel belt terminating device, the second steel belt terminating deviceand the driving device are arranged side by side in the horizontal length direction of the bearing wheel. The elevator has the characteristics of high space utilization rate, high safety and low maintenance cost.

Description

technical field [0001] The invention relates to a car frameless elevator, in particular to a car frameless elevator driven by a traction steel belt. Background technique [0002] At present, the traction system used for the elevator car is generally composed of a traction machine, a load-bearing device, a traction wire rope, a guide wheel and a brake. Behind the guide wheels at the bottom of the car, the car is driven by the traction machine to realize the stable lifting of the car; and the car frame is used as the external bearing mechanism of the car, which is set outside the car and equipped with guide wheels, Elevator guide shoes and brakes enable the external force to be evenly transmitted to the car through the car frame, ensuring the force strength and stable operation of the car. However, since the car frame will occupy the space on the top and both sides of the car after installation, the carrying space inside the car will be reduced, the space utilization rate of ...

AI Technical Summary

Problems solved by technology

In addition, because the rope head plate currently used to fix the wire rope is generally placed side by side with the traction machine on the top of the hoistway, the wire rope cannot pass through the elevator load-bearing device and the pulley of the traction machine in sequence at a vertical angle when threading, thereby aggravating the tension of the wire rope. wear and further reduce the safety of the elevator load-bearing device

Therefore, the existing elevator car frame and traction structure have the problems of low space utilization, low safety and high maintenance cost
