We are naturally not unfamiliar with automatic barriers, because we will see it from time to time. The gates of the community can be seen. The highway exits and entrances can be seen. We can still see the entrances and exits of public places. Let's take a look at how automatic barrier works.
In fact, the working principle of the automatic barrier is such that the control panel of the barrier will control the motor according to the operation instructions. During the control, forward reversal is performed; then the motor will drive the relevant reducer to promote the rotation of its input shaft; the decelerator will decelerate the output shaft and drive the rocker arm to rotate up and down at 180o in the latter half of the cycle; The arm drives the spindle drive arm to move up and down within 90o of the rear half through the lower articular bearing, connecting rod and upper joint bearing. The spindle drive arm drives the brake lever connected to the main shaft to make a vertical movement within 90o horizontal and vertical range. The above situation can be electric or automatic, depending on how it is controlled. We say that the series of actions of the automatic barrier-related brake levers in lifting to the limit of the vertical position is controlled by a vertical position sensor. The sensor is mounted on a vertical magnet sensing bracket which is located on the cam;
So we can know that the horizontal position is the same as the vertical position, that is, it is controlled by the level magnet to sense the level Hall sensor.
Once the automatic barrier power failure, we can insert the crank through the hole in the back of the gate. Thus, the manual crank input shaft is caught, and the rocker lifts the brake lever.
