Description

technical field [0001] The invention relates to a gate for controlling fluid, in particular to an opening and closing device for a quick-closing gate with double suspension points. Background technique [0002] With the development of fluid control technology, especially the acceleration of urban modernization, the problem of water control has become more prominent. At present, all the gate opening and closing devices used for water control gates are single-point quick-closing gate opening and closing devices. The structure is that a motor, a ball nut and a lead screw are installed side by side on the housing, a gear is installed on the ball nut, and a micro switch is installed on the motor. The output shaft is equipped with a de-energized electromagnetic clutch, and the other end of the clutch is equipped with a driving gear and a damper. The driving gear meshes with the ball nut gear through an intermediate wheel, and a buffer is installed on the shell supporting the ball ...
