导致电动卷帘门脱钩危险现象发生的几种情况

因为卷帘门由端板、卷帘轴、卷帘门电机、传动链、导轨、卷帘门、控制箱等部件组成。卷帘门的上下滑动需要在导轨中实现。如果卷帘门出轨，就会出现卡死现象，容易上下或不能上下。该现象发生在以下几种情况：

Because the roller shutter door is composed of end plate, roller shutter shaft, roller shutter motor, transmission chain, guide rail, roller shutter door, control box and other components. The up and down sliding of the roller shutter door needs to be realized in the guide rail. If the rolling shutter door is derailed, it will be stuck, easy to go up and down or unable to go up and down. This phenomenon occurs in the following situations:

1、卷帘门轴管断裂。2、卷帘门轴管固定座螺栓松动，使固定座脱落。3、卷帘门轴管与固定座螺丝脱落，使轴管固定分离。4、卷帘门扇的连接脱钩，或与轴管的固定螺丝松动，使门片脱落。5、门片卡住后，用力拉动，使刀片脱节。务必排除故障以进行维修。

1. The roller shutter shaft tube is broken. 2. The bolts on the fixed seat of the roller shutter shaft tube are loose, causing the fixed seat to fall off. 3. The screw of the roller shutter door shaft tube and the fixed base falls off, so that the shaft tube is fixed and separated. 4. The connection of the rolling shutter door leaf is unhooked, or the fixing screw with the shaft pipe is loose, so that the door leaf falls off. 5. After the door piece is stuck, pull hard to make the blade out of joint. Always correct the problem for repair.

预防措施：

Precautions:

1、安装过程中一定要注意线路的完整性，规范操作，安装卷帘门。

1. During the installation process, attention must be paid to the integrity of the circuit, standardized operation and installation of roller shutter doors.

2、在使用卷帘门时，要注意卷帘门轨道和吊轮不能涂油，否则吊架上的滚轮会滑动，导致门体相撞。

2. When using the rolling shutter door, it should be noted that the rolling shutter door track and lifting wheel should not be oiled, otherwise the roller on the hanger will slide, causing the door body to collide.

3、电动卷帘门脱轨脱钩也可能是线路问题。可能是控制线路中的某条线路连接不正确，也可能是在搬运过程中线路断了。在检查其他项目之前，优先检查并排除电路问题。例如，检查电机引线和继电器的插头是否因振动而脱落，导致故障。

3. The derailment and decoupling of the electric roller shutter door may also be a line problem. It may be that one of the control lines is incorrectly connected, or it may be that the line is broken during handling. Check and eliminate circuit problems before checking other items. For example, check whether the plug of motor lead and relay falls off due to vibration, resulting in failure.

此外，还有许多注意事项需要注意，例如：

In addition, there are many considerations to be noted, such as:

卷帘门电机的选购也是比较重要的一环。切记不要觉得提升力不够，因为卷帘门电机的承载能力会随着时间的推移而逐渐降低实际的提升效果，所以尽量选择材料。超过窗帘的实际升力。

The purchase of roller shutter motor is also an important part. Remember not to feel that the lifting force is not enough, because the bearing capacity of the roller shutter motor will gradually reduce the actual lifting effect over time, so try to choose materials. Exceeds the actual lift of the curtain.

卷帘门具有防推装置，防止门体被强行推挤，具有安全防盗的特点。后卷帘卷起在车门上部，节省车库内部空间，不会将泥、雨、雪等杂物带入车库，美观大方

The rolling shutter door has an anti pushing device to prevent the door body from being pushed by force, which has the characteristics of security and anti-theft. The rear roller shutter is rolled up on the upper part of the door to save the internal space of the garage and will not bring mud, rain, snow and other sundries into the garage. It is beautiful

济南电动卷帘门安装维修人员提醒您，选择卷帘门时，要观察卷帘门是否可以手动操作，还要保证手动操作的灵活性和稳定性。为了保证卷帘门的安全，我们要求卷帘门具有双面自锁功能，并保证卷帘门不会因惯性而自由滑动。卷帘门的结构要足够精密，散热要符合要求。

Jinan electric roller shutter door installation and maintenance personnel remind you that when selecting roller shutter door, you should observe whether the roller shutter door can be operated manually, and ensure the flexibility and stability of manual operation. In order to ensure the safety of the rolling shutter door, we require that the rolling shutter door has a double-sided self-locking function, and ensure that the rolling shutter door will not slide freely due to inertia. The structure of the rolling shutter door shall be precise enough, and the heat dissipation shall meet the requirements.
