Barrier gate capable of running without spring

The barrier gate comprises a machine base, a motor is fixed to the machine base, a worm is fixed to one end of a driving shaft of the motor, a worm gear is connected to the worm in a transmission mode, the worm is a multi-thread worm, the worm gear drives a swing rod shaft to swing through a speed reducing mechanism, and the swing rod shaft is connected with the motor. The swing rod is fixed to the end of the brake bar in the radial direction, the motor is controlled by a controller, and the motor is controlled by the controller to form a short circuit during power failure. The device has the advantages of being simple in structure, convenient to use, easy to debug, capable of reducing maintenance and long in service life. 本发明公开了一种可以无簧运行的道闸，包括机座，所述机座上固定有电机，所述电机的驱动轴的一端固定有一蜗杆，所述蜗杆上传动连接有一蜗轮，所述蜗杆为多头蜗杆，所述蜗轮通过减速机构传动一摆杆轴摆动，所述摆杆径向固定闸杆的端部，所述电机受控于一控制器，所述电机由控制器控制其在停电时形成短路。本发明具有结构简单、使用方便、调试简单、减少维护、使用寿命长的优点。
