Free falling type fireproof rolling shutter door
The invention provides a free falling type fireproof rolling shutter door which is characterized in that a bottom cover capable of being opened and closed is arranged at the bottom of a door box, the two sides, in the length direction, of the bottom cover are hinged to the two sides of the door box respectively and connected with an electromagnetic lock, and the electromagnetic lock is connected with a manual controller or a central controller; the fireproof roller shutter is rotationally installed in the door box through a rolling shaft, one end of the rolling shaft penetrates out of one side of the door box and is fixedly connected with a bearing seat, the bearing seat is connected with a one-way bearing, a rolling seat of the one-way bearing is connected with a motor, when the bottom cover is opened, the fireproof roller shutter freely falls down under the dead weight, and when a fire is over, the motor drives the rolling shaft to rotate, so that the fireproof roller shutter is opened. Therefore, the fireproof roller shutter is rolled up; the fireproof roller shutter is made of silicon-titanium coating fireproof cloth. The fireproof rolling shutter door can isolate fire in the first time and avoid fire spreading, and the fireproof rolling shutter door is light in self weight, suitable for buildings with small bearing capacity and suitable for places with extra-large fireproof span.
本发明提供了一种自由垂落式防火卷帘门，门箱的底部设置有可开闭的底盖，底盖沿长度方向的两边与门箱的两边分别进行铰接和电磁锁连接，电磁锁与手动控制器或中心控制器连接；所述防火卷帘通过卷轴转动安装于门箱内，卷轴的一端从门箱的一侧穿出，并固定连接有轴承座，轴承座连接有单向轴承，单向轴承的滚动座连接有电机，当底盖打开时，防火卷帘在自重下自由垂落，当火情结束时，电机驱动卷轴转动，从而将防火卷帘卷起；所述防火卷帘为硅钛涂层防火布制成。该防火卷帘门能够第一时间隔离火情，避免火势蔓延，且该防火卷帘门自重轻，适用于承载力小的建筑物，并适用于防火跨度特大的场所。
