An elevator emergency rescue counterweight opposing traction mechanism

Abstract

The invention discloses an elevator emergency rescue counterweight opposing traction mechanism, which belongs to the field of elevators and includes a control system, an installation platform, and a car. A traction machine is installed on the top wall of the installation platform. The machine is equipped with a traction wheel through the traction shaft, and the end of the traction shaft away from the traction machine is equipped with a first worm wheel, the first worm wheel meshes with the first worm, and the two ends of the first worm are respectively connected with the protection Drive end installation of motor and rescue motor. The elevator traction mechanism of the present invention, on the one hand, through the first worm gear meshing with the first worm, and the setting of the protection motor and the rescue motor, can avoid the elevator operation failure caused by the failure of the traction machine; The clamping force of the traction rope increases the friction, so that the auxiliary drive can be carried out when the traction machine is running, and the slip between the traction rope and the traction wheel can be avoided. In addition, when the traction machine stops, the friction force can also be used , increase the braking force on the car.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a counterweight opposing traction mechanism for emergency rescue of elevators. Background technique [0002] Elevator refers to a permanent transportation device that serves several specific floors in a building, and its car runs on at least two rows of rigid tracks perpendicular to the horizontal plane or with an inclination angle of less than 15° to the plumb line. [0003] At the end of the 20th century, the elevator used permanent magnet synchronous traction machine as power. It greatly reduces the area of ​​the computer room, and has the advantages of low energy consumption, energy saving and high efficiency, and fast lifting speed, which greatly promotes the development of real estate in the direction of super high-rise buildings. [0004] After retrieval, Chinese Patent No. CN109665426A discloses an elevator counterweight opposite traction mechanism, which aims to solve...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, the braking reliability of the elevator traction mechanism is not good, the safety is not high, and there is a risk of slipping between the traction sheave and the traction rope. Therefore, the safety performance of the elevator cannot be guaranteed, and occurrence of The probability of accidents is high, which is not conducive to the safety of elevator operation and the self-rescue of elevator passengers. Therefore, the present invention proposes a traction mechanism with opposite counterweights for elevator emergency rescue.
