Problems solved by technology
However, due to the influence of the external environment, it is difficult to install the control elements of each layer on the frame. Even if they are installed, the guide wheels of the hanging basket and the guide rails of the frame cannot achieve a certain precision. Variations, lift gondolas are often not positioned exactly parallel to the floor

The invention relates to an automatic flat-layer device for elevator. Based on the movement of nut slide block on the screw-rod the cage of the elevator is positioned, and uses a pressure-roller loading sensor and one lever-type load sensing regulator to regulate accuracy to attain the goal of automatic flat-layer. At the same time the lever-type load sensing regulator also can have the action ofload-limiting protection for elevator.
Description
(1) Technical field [0001] The invention relates to an elevator, in particular to an automatic leveling device of the elevator, which belongs to the leveling control system for the automatic operation of the elevator. (2) Background technology [0002] In order for the elevator gondola to stop smoothly and be at the same level as the platform threshold of this floor, a method must be used to allow the elevator to recognize that it has reached the designated floor. An existing method is to install a Hall effect element as an inductor on the position corresponding to each layer on the frame, and install a magnet on the elevator basket. When the Hall effect element senses the change of the magnetic field, it will give A signal from the elevator control system, the control system controls the motor to stop working, and the elevator stops accordingly. However, due to the influence of the external environment, it is difficult to install the control elements of each layer on the f...
