Novel elevator releveling device

Abstract

The invention discloses a novel elevator releveling device, and relates to the field of elevator releveling. The novel elevator releveling device comprises a car frame and a car arranged in the car frame; the upper end and the lower end of the car frame are connected with the upper end and the lower end of the car through an elastic structure correspondingly; and a traction connection piece is arranged at the upper end of the car frame, and a leveling sensor is arranged on the car. The novel elevator releveling device is characterized in that the upper end of the car frame is provided with a winding strip fixing piece and a winding wheel; and the lower end of the car is provided with a fixed pulley, one end of a winding strip is fixed to the winding strip fixing piece, the other end of thewinding strip bypasses the fixed pulley to be connected to the winding wheel, and the winding strip has the certain winding amount on the winding wheel, so that certain tensioning force of the winding strip exists between the car frame and the car, and the winding wheel rotates to change the winding amount of the winding strip, so that releveling of the car is conducted. The novel elevator releveling device has the advantages that the structure is simple, and accurate and safe releveling can be achieved.

Description

technical field [0001] The invention relates to the field of elevator releveling, in particular to a novel elevator releveling device. Background technique [0002] With the continuous deepening of the urbanization process, more and more high-rise buildings have begun to rise in the city, and the architectural space of the city is continuously extending in the vertical direction, and the floors are getting higher and higher. However, the higher the floor, the longer the total length of the wire ropes connecting the host and the car in the elevator. The steel wire rope has a stretching amount, and the stretching amount of the steel wire rope per unit length is constant. The longer the steel wire rope, the greater the final total deformation. In this way, when the elevator is on the leveling floor, as the number of passengers entering the car increases or decreases, the elevator car will move down or up. People entering and leaving the car cause potential safety hazards. ...

AI Technical Summary

Problems solved by technology

However, this solution has great potential safety hazards. When the elevator is leveling, the parking position of the car depends entirely on the brake of the main engine of the elevator. Passengers are entering and leaving. If the brake is opened at this time, it is pulled by the torque of the main engine. Steel wire rope, if the torque is not enough, reversed, etc., the car will suddenly slide down, which is very dangerous
