Door body falling automatic protection device and lifting door
According to the automatic door body falling protection device and the lifting door, the outer wall of a shaft sleeve is rotationally connected with a stopping block through a stopping block torsional spring, and a braking part is arranged on the stopping block; when the pull rope is tensioned, circumferential torque is applied to the shaft sleeve, the shaft sleeve drives the backstop torsional spring through the circumferential torque, then the braking part of the backstop abuts against the blade assembly, and the end of the blade assembly keeps a distance from the guide rail. When the pull rope is loosened, the circumferential torque disappears, the backstop torsional spring drives the backstop to reset, the backstop is separated from the blade assembly, and then the blade assembly prevents the door curtain from descending. The backstop for preventing the blade assembly from playing a braking function is arranged in the rotating direction of the blade assembly, so that misoperation of the blade assembly is avoided, and the safety performance of the lifting door is improved.
门体坠落自动保护装置及提升门，轴套的外壁通过止挡扭簧与止挡可转动连接，止挡上设有制动部；拉绳拉紧时对轴套施有周向扭矩，轴套通过周向扭矩带动止挡扭簧，进而使得止挡的制动部顶住刀片组件，使其端部与导轨保持距离；拉绳松脱时周向扭矩消失，止挡扭簧带动止挡复位，使其与刀片组件脱离，进而刀片组件阻止门帘下降。通过在刀片组件的旋转方向上设置阻止其发挥制动功能的止挡，避免其产生误动作，使得提升门的安全性能提高。
