Soft drive door without mechanical connecting rod

Abstract

The invention relates to the technical field of elevator industry, and in particular relates to a soft drive door without mechanical connecting rod, the soft drive door comprises a left door, a right door, a motor, a gearing-down platform and a transmitted platform, wherein a reduction gear is fixedly arranged on the gearing-down platform, the spindle of the motor is connected with a first-stage gear which is also connected with the reduction gear through a main gear belt, the reduction gear is connected with a two-stage gear through a rotating shaft, a driven gear is fixedly arranged on the transmitted platform and connected with the two-stage gear through a gear transmission belt on which a left slider and a right slider are symmetrically and fixedly arranged, the left slider is fixedly connected with the top end of the left door, the right slider is fixedly connected with the top end of the right door, and the motor is also connected with a rotary encoder. When in use, the soft drive door without mechanical connecting rod is high in transmission efficiency, low in failure rate and running noise, and capable of avoiding slipping and ensuring accurate positioning. The soft drive door without mechanical connecting rod has the advantages of simple structure, rational arrangement, low manufacture cost and the like.

Description

technical field [0001] The invention relates to the technical field of the elevator industry, in particular to a non-mechanical linkage soft transmission door. Background technique [0002] The elevator door is the passage for passengers to enter and exit the elevator car after the elevator stops on the leveling floor. The elevator door system is composed of door machine, car door, hall door and safety protection device. The door motor drives the mechanical transmission mechanism after the speed regulating device receives the control door switch signal to drive the car door switch. As an active door, the car door drives the hall door to move synchronously through door knife, door wheel and other devices. In order to prevent people from being caught in the process of closing the door, there are protective devices such as people being caught and re-opening the door. Our country produces 40,000 elevators annually, and 400,000 elevators are currently in use. In recent years, ...

AI Technical Summary

Problems solved by technology

The mechanical part of the traditional elevator door machine often uses the motor to decelerate through the gear reducer first, and then drives the car door switch through the connection of the mechanical connecting rod. The mechanical structure is complicated, the transmission efficiency is low, and the adjustment is difficult, and the failure rate is high; Pressure and shunt mode for speed regulation control, not only high energy consumption, high noise, but also poor reliability
