Curved elevator door operator

Abstract

The invention relates to an arc-shaped elevator door machine, and provides an arc-shaped elevator door machine which is simple in structure, stable in performance, compact in structure and convenient to install, maintain and adjust. The arc-shaped elevator door machine comprises dragging devices, door cam devices and a drive adjusting device. The arc-shaped elevator door machine is characterized in that the drive adjusting device comprises a linear drive device, adjusting arms, swinging arms and swinging arm supports, and the linear drive device controls the rotating angle of each swinging arm through the corresponding adjusting arm; and the end, far away from the corresponding support, of each swinging arm is connected with the corresponding door cam device, and each swinging arm drives the corresponding dragging device to move through the corresponding door cam device.

Description

technical field [0001] The invention relates to a curved elevator door machine. Background technique [0002] The elevator door operator is a mechanism responsible for opening and closing the elevator hall car door. When it receives the elevator door opening and closing signal, the elevator door operator controls the door opening motor through its own control system, and converts the torque generated by the motor into a specific direction. force to close or open the door. When the force that prevents the door from closing is greater than the specified value, the door operator will automatically stop closing the door and open the door in reverse, playing a certain degree of door closing protection. [0003] Chinese utility model patent, arc-shaped door, publication number CN204079200U, publication date 2015.01.07, discloses an arc-shaped door operator, including ball screw, screw nut, screw support, door operator lever and door knife . The two ends of the ball screw are sl...

AI Technical Summary

Problems solved by technology

Although it drives the reverse rotation of the left and right ball screw through the servo speed regulating motor, the screw nut realizes the left and right reciprocating uniform speed movement on the screw, thereby driving the two door machine levers and the door knife to open and close to move left and right, and the power is evenly distributed. It is transmitted to the two doors, making the opening and closing of the two doors more safe, precise and free, but it has the following disadvantages: 1. The structure is not compact and the space is large; 2. The power is transmitted through the left and right screw, and the opening angle of the door operator The bigger the load, the bigger the load, the lead screw is easy to deform, and the door opening size is small; 3. The arc door needs to be installed as a whole, and the installation accuracy is high. There are too few adjustment points. If there is eccentricity, the overall adjustment is required, and the adjustment is time-consuming and laborious. Installation and maintenance Debugging is inconvenient
