使用相对频繁的卷帘门来说重要的两个方面
来源:http://www.jnzxmy.com 日期:2022-12-20 发布人:
对于使用相对频繁的电动卷帘门来说,电控系统的限位准确性和保护是重要的两个方面。今天济南卷帘门厂家就一次性将这些问题说个清楚。
For the electric roller shutter doors which are used frequently, the accuracy of limit and safety protection of the electric control system are two important aspects. Today, the manufacturer of Jinan roller shutter door explained these problems at one time.
限位准确
Accurate limit
一樘电动卷帘门,电机应该在门开到什么位置的时候停,不停会怎样?门关到什么位置停,不停又会怎样?
For an electric rolling shutter door, the motor should stop when the door is opened to what position. What will happen if the motor does not stop? Where does the door close and stop?
电动卷帘门是在电机带动下将帘板卷绕在门轴上,如果门开到高位置,电机没有及时停住,就会将帘板从门框中强制甩出,继而发生坠落伤人危险。
The electric rolling shutter door is driven by the motor to wind the shutter on the door shaft. If the door is opened to a high position and the motor does not stop in time, the shutter will be forced out of the door frame, and then fall and hurt people.
如果门关到低位置(地面),电机没有立即停住,而是继续带动帘板向下,帘板则会逐级向下挤压,导致门板变形,久而久之将无法正常关门。如下图这樘门。
If the door is closed to the low position (ground), the motor does not stop immediately, but continues to drive the shutter downward, and the shutter will be squeezed downward step by step, resulting in deformation of the door panel, and it will be unable to close the door normally over time. The door is as shown in the figure below.
卷帘门电控系统配备的数字式编码器,在安装时可自动进行门帘启停位置学习,位置精准,长时间使用后也不会跑偏,确保卷帘门启闭正常。
The electric control system of the roller shutter is equipped with a professional digital encoder, which can automatically learn the starting and stopping positions of the shutter during installation. The position is accurate, and it will not deviate after a long time of use, so as to ensure the normal opening and closing of the roller shutter.
保护
safeguard
除此之外,卷帘门的性也不容忽视,比如门帘坠落的问题,卷人、压人的问题等等,近年来时常见诸于报端。
In addition, the safety of rolling shutter doors can not be ignored, such as the problems of falling curtains, rolling people, pressing people, etc., which are common in the newspapers in recent years.
卷帘门内置扭矩保护装置,无论何种原因引起的扭矩异常,电机都能自动触发并锁住门轴,防止门帘坠落。
The rolling shutter door is equipped with a built-in torque protection device. No matter what causes abnormal torque, the motor can automatically trigger and lock the door shaft to prevent the curtain from falling.
一些事故都是卷帘门在开启和关闭过程中,电控系统没有检测到门帘下方的人员所导致。特别是一些民用场所,由于门本身不大,容易引起儿童的好奇心,在开门时攀爬玩耍而导致事故。针对此类危险,卷帘门在保障通行方面设置了层层保护:
Some accidents are caused by the failure of the electric control system to detect the personnel under the curtain during the opening and closing of the rolling shutter door. Especially in some civil places, because the door itself is not large, it is easy to arouse children's curiosity and cause accidents when they climb and play when opening the door. In view of this kind of danger, roller shutter doors are provided with layers of protection to ensure traffic safety:
一、开/关门力保护功能。当有人员或车辆在关门路径上停留时,电机检测到阻力即刻停止关门。同样,当门开启时,如有人扒住门帘,电机将检测到门帘重量异常,停止开启动作。
1、 Opening/closing force protection function. When a person or vehicle stops on the door closing path, the motor will stop closing the door immediately when it detects resistance. Similarly, when the door is opened, if someone grabs the curtain, the motor will detect that the curtain weight is abnormal and stop opening.
二、底部光电保护功能。对于大尺寸的工业卷帘门,配备底部光电保护装置,在与地面接触的橡胶软底边内置红外光眼,关门时触碰到障碍物,将触发光眼保护,电机随即停止关门动作,防止危险的发生。
2、 Photoelectric protection function at the bottom. For large-sized industrial roller shutter doors, the bottom photoelectric protection device is equipped. An infrared optical eye is built in the rubber soft bottom that contacts the ground. When the door is closed, the optical eye protection will be triggered when the obstacle is touched, and the motor will stop closing the door immediately to prevent the occurrence of danger.
