Background
With the continuous deepening of the urbanization process, more and more high-rise buildings start to be pulled out of the ground in the city, the building space of the city continuously extends towards the vertical direction, and the floors are higher and higher. However, the higher the floor, the longer the total length of the wire rope connecting the main machine and the car in the elevator. The steel wire rope has a certain expansion amount, and the final total deformation amount is larger as the steel wire rope is longer. Therefore, when the elevator is on a flat floor, the elevator car moves downwards or upwards along with the increase or decrease of the number of passengers entering the car, and the bottom of the car and the landing sill at the moment are not on the same plane, so that potential safety hazards can be caused to people entering and exiting the car.
The existing automatic re-leveling function is generally realized as follows: when the lift car moves downwards or upwards for a distance exceeding a specified value, the control system controls the main machine to open the band-type brake, and the main machine rotates to lift or lower the lift car, so that the lift car achieves the aim of leveling again. However, the scheme has great potential safety hazard, when the elevator is on a flat floor, the stopping position of the elevator car is completely dependent on the brake of the main machine of the elevator, passengers enter and exit, if the brake is opened at the moment, the steel wire rope is pulled by the torque of the main machine, and in case that the torque is insufficient, the elevator car is reversed, the elevator car suddenly slides down, and the danger is great.
