Gear-transmission-based automatic vertical hinged door

Abstract

The invention discloses a gear-transmission-based automatic vertical hinged door which consists of a door body and a drive control mechanism; the drivinge control mechanism is fixed at the lower part of the door body, and is vertically installed with the door body at a same plane; the drive control mechanism controls an electric cylinder to push a rack to linearly move, the rack drives a driving gear to rotate, the driving gear drives an intermediate gear to positively rotate at a constant speed by a connecting rod, and the intermediate gear drives a driven gear to reversely rotate at a constant speed. The constant-speed and reversed rotation of the driving gear and the driven gear drives a driving shaft and a driven shaft to rotate in a constant-speed and reversed way, so that the constant-speed and reversed rotation of the two shafts of the vertical hinged door can be realized; and the automatic opening and closing of the vertical hinged door can be realized under the driving of a control mechanism. The gear-transmission-based automatic vertical hinged door is simple to operate and install, and safe and reliable; and the span of the automatic vertical hinged door can be large and small, so that the work occasions under different environments can be met. The gear-transmission-based automatic vertical hinged door is particularly suitable for hall doors in the places such as government agencies, hotels, office buildings, banks, and hospitals, garage doors of companies, etc.

Description

technical field [0001] The invention belongs to the technical field of mechanical design and manufacture, and relates to an automatic door with a mechanical structure, in particular to an automatic swing door based on gear transmission. Background technique [0002] At present, many kinds of automatic swing doors are widely used. The driving transmission device is mostly composed of electric motor and reducer, or electric motor and hydraulic system. It works according to the program set by the command driving device of the control system to drive the door body to open and close. From the working principle, it can be divided into full electric automatic swing door, semi-electric automatic swing door, and electrohydraulic automatic swing door. [0003] all electric automatic swing door , the process of opening and closing the door is driven by the controller and the motor. The controller must use the program setting in the microprocessor to control the movement of the door a...
