A core device for a revolving door in an access control system

Abstract

A movement device for a revolving door in an access control system, including a door leaf driving device composed of a motor and bevel gears, the door leaf driving device is fixedly connected to a frame, and its rotating output end is fixedly connected to the rotating shaft of the door leaf through a shaft sleeve . The door leaf driving device is also connected with a door turning device through the bevel gear to drive the slider through the screw shaft and compress the spring to store energy, and a brake and torque limiting device with a jaw brake connected through the connecting shaft. The invention is used in various access control systems in rail traffic such as subways, railways, and light rails. When the system is powered off, the door can be opened automatically, so that people can escape from the passage of the access control system. When the door is pushed forcibly, it will be opened at an angle to prevent accidents. The invention is small in size, easy to install, and has a higher safety level. In addition, door panels with suitable shapes can be selected by replacing door panel components according to different shapes of ticket gates, so as to achieve universal interchangeability of equipment parts.

Description

technical field [0001] The invention relates to a revolving door in an access control system, in particular to a movement device for the revolving door in the system. Background technique [0002] In the prior art, the access control systems in the automatic ticket checking systems used in rail transit such as subways, railways, and light rails include scissor doors, flapping doors, three-bar doors, and the like. The forms and conditions of use of various doors are also different, including that most of the current flapping doors adopt foreign technology, and most of them use integrated shafts, so they take up a lot of space and require high installation. In addition, when passing through the ticket gate by swiping the card, when someone is caught in the middle of the door leaf, it cannot be actively monitored and rescued from the door without cutting off the power supply or closing the passage. When the door is closed, the door can be opened automatically through the mecha...
