Title A Three-dimensional Structure Design of
Gates Swing Door
Abstract
On the basis of the analysis in the functionality and performance of the gates swing door, and consult a lot of information to formulate the overall structure of the gates swing door design. It is achieved swing door quickly and accurately switch by the use of notch evenly distributed positioning plate and positioning wheel cooperating with each other. At the same time it is achieved real-time measurement of the switching angle of the swing door by the use of encoder and photoelectric switches. Torque coupling form of the function of the overload protection to achieve the safety requirements of the gates swing door running. The use of transmission and electromagnetic brake to match the form of the braking effect of the swing door. Three-dimensional modeling method provides a design basis and foundation for the agency size calculations and 3D design work. There is a Pro / E three dimensional figure and a planar engineering drawing in the end of this thesis.

1.1 闸机系统
闸机是一种集高精度机械结构与先进的微电子控制技术为一体的人流通道的出入口智能控制终端设备，主要用于地铁站、火车站、轮渡站、旅游景点、娱乐场所等人群流动性大的公共场所出入口管理，它的使用可以使人流有序的通过通道。闸机在地铁应用中即是自动检票设备，是城市轨道交通的AFC系统中的关键设备之一，各个车站的进出口均有安装，乘客进出车站均要经过闸机[1]。
