An adaptive anti-rebound emergency protection device for elevators

Abstract

The invention discloses a self-adaptive elevator anti-rebound emergency protective device and belongs to the field of elevator safety. The self-adaptive elevator anti-rebound emergency protective device comprises an elevator liftway and an elevator car. The elevator car is located intelligent the elevator liftway. The upper end of the elevator car is fixedly connected with a traction safety bracket. The upper end of the traction safety bracket is fixedly connected with a hoisting rope. The end, far away from the traction safety bracket, of the hoisting rope is fixedly connected with a balancing block. The lower end of the elevator car is provided with an elevator car protection mechanism. The lower end of the elevator car protection mechanism is fixedly connected with a protective base. The self-adaptive elevator anti-rebound emergency protective device can retard rebound of spring structures of the elevator car protection mechanism to the elevator car when the elevator car protectiondevice conducts buffering on the elevator car. Accordingly, the self-adaptive elevator anti-rebound emergency protective device extends the protection function of the elevator car protection device when an emergency situation occurs to an elevator. Damage to elevator equipment due to the unexpected situation is reduced. Meanwhile, the protection effect of the elevator car protection device on people in the elevator car is further improved.

Description

technical field [0001] The invention relates to the technical field of elevator safety, in particular to an adaptive anti-rebound emergency protection device for elevators. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical transportation ...

AI Technical Summary

Problems solved by technology

In the above technical solution, when an unexpected situation occurs in the elevator car, the emergency buffer device needs to protect the elevator car part. The existing car protection devices all need a spring structure to buffer the car, and the spring structure is installed in the car. Both play a vital role in the protection device, but the traditional spring structure will rebound quickly with the pressure after being compressed, and the rebound speed is positively correlated with the pressure, that is, when the elevator car is on the protection device The greater the pressure of the spring structure in the spring structure, the greater the rebound speed of the spring structure pushing the elevator car in the opposite direction, and the car protection device needs to work only when the elevator is out of control, so the car protection device is generally affected by the force from the elevator car. The pressure at the end of the car is very huge. Under the rebound of the car protection device, not only the internal equipment of the car is easily damaged, but also the people inside the car are extremely vulnerable to secondary injuries.
