    1.卷帘设计:济南卷帘门采用对开形式,在洞口两端设置机箱,一般情况下,卷帘门收于机箱内,当发生火灾时,机箱内主电机通过齿轮传动将防火卷帘沿轨道送出。卷帘沿轨道相对运行,直至闭合,返回关闭信号,电机停止工作。卷帘收回时原理相同。
    shutter design: rolling door uses on the open form, set the chassis in the hole at both ends, in general, rollingshutter door to the case, when the fire occurs, in the case of main motor through the gear drive will be fireproofrolling along the track out. Rolling along the orbit operation until closing, returns close signal, the motor stopsworking. Rolling back when the same principle.
    2.卷帘门轨道设计:轨道采用方管作为卷帘运行的滑道,上导轨通过固定件与梁或楼板进行固定。轨道根据洞口形状分段加工,现场拼接。通过对其他工程侧向卷帘门的调研并结合卷帘门生产厂家的经验,转角段半径设计为1500mm,既保证了设计要求,又可以使卷帘顺利通过,效果较好。为了保证装饰效果,上轨道隐藏于吊顶内,·取消下轨道,严格控制帘板与地面之间的缝隙,符合火、防烟要求。
     rolling door track design: track with square tube as slideway shutter operation, on the guide rail through fixedwith beamor floor fixing piece. According to the shape of hole trajectory piecewise processing, field splices.Through investigationand Research on the other side roller shutter door engineering and combined with the rollingshutter door manufacturers experience, corner radii of design for 1500mm, not only to guarantee the designrequirements, and can make the rolling pass smoothly, the effect is better. In order to ensure the decorativeeffect, on track hidden in the ceiling, and cancel the next track, strictly control the gap between the curtainplate and the ground, meet the fire and smoke prevention requirements.
    3.卷帘门电机设计:机箱内有2台主电机,1台为闭合电机,1台为开启电机,通过传动装置对卷帘进行开启及关闭。在送出卷帘时,由于卷帘跨度很大而且为异形结构,这就给卷帘的运行带来很大的困难,完全依靠机箱内主电机的推力是不能满足卷帘运行直闭合状态,为此加装助力电机;助力电机的输出转矩与主电机相同,运行过程与主电机同步。
     the design of rolling door motor: the chassis has 2 sets of main motor, 1 sets of closed motor, 1 stations for theopening of motor, shutter for opening and closing through the transmission device. After sending the shutter,
    rolling shutter span is large and is due to an anomalous structure, which will bring great difficulty to theoperation of the shutter, completely rely on the chassis of the main motor thrust is can not meet the shutter runstraight closed state, thus adding power motor; the output torque of motor for electric power and the same as themain motor, synchronous operation process and main motor.
