Problems solved by technology

, due to manual operation, the leveling of the car is often inaccurate, and it is often necessary to repeatedly click the control button several times to make the elevator car basically stop at the leveling position
Operators are time-consuming and laborious, and the effect of car leveling is not very good
[0003] Although some units have also developed some automatic leveling control devices for elevators, such as the control system that uses gear pulses to detect floor heights, the accuracy is not high enough to fully meet the requirements for automatic leveling of elevators in practical applications.

Embodiment Construction

[0018] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0019] Such as figure 1 Shown: an automatic leveling control device, including a main control board 1, a keyboard 2, an encoder 3 installed on the gear shaft of the elevator, and a display screen 4 installed in the elevator car; the main control board 1 is connected to the The display screen 4, keyboard 2 and encoder 3; the main control board 1 is also connected to the electric controller of the elevator through the output interface on the main control board 1.

[0020] The working principle of the present invention is as follows: the improvement of the present invention lies in the added encoder 3, the encoder 3 is installed on the gear shaft of the elevator, and as the gear shaft rotates, the encoder 3 turns according to the number of turns of the gear shaft and angle, output the number of pulses corresponding to the lift car's rising or falling height. For...

Abstract

The invention discloses an automatic leveling control device. The automatic leveling control device comprises a main control panel, a keyboard, an encoder arranged on a gear shaft of an elevator, and a display screen arranged inside a car of the elevator, and the main control panel is connected with the display screen, the keyboard and the encoder and is further connected with an electric controller of the elevator through an output interface of the main control panel. Further, the main control panel comprises a pulse zero clearing interface with is connected with a travel switch arranged at the bottom of the elevator. Further, the inside of the output interface of the main control board is provided with a relay. The main control panel further comprises an alarm interface. The automatic leveling control device enables the elevator to have an automatic leveling function and greatly improves the accuracy of leveling.

Description

technical field [0001] The invention relates to an elevator control device, in particular to an automatic leveling control device for an elevator. Background technique [0002] Most of the elevators used in construction currently use manual control to achieve lifting, and special operators manually control the lifting of the elevator car. When it is necessary to ascend or descend, press and hold the corresponding control button, and when reaching a certain floor and the elevator car needs to stop, release the control button. , because it is manual operation, the leveling of the car is often inaccurate, and it is often necessary to repeatedly click the control button several times to make the elevator car basically stop at the leveling position. The operator is time-consuming and laborious, and the effect of car leveling is not very good. [0003] Although some units have also developed some elevator automatic leveling control devices, such as a control system that uses gea...
