What Is a Roller Gate?

Rolling shutter doors are connected in series by multi-joint door panels, and in a fixed slide, the upper and lower doors are rotated around the shaft above the door. Roller shutter doors are commonly used in shops.

1. According to the opening type , the rolling door can be divided into: manual

Rolling shutter door is mainly composed of door body, driver and control system. The door body is made of high-quality stainless steel and aluminum alloy special profiles, and is hinged by the principle of parallelogram, which has a large telescopic and flexible stroke. The driver is driven by a special motor, the worm and worm gear are decelerated, and a manual clutch is provided. It can be manually opened and closed when the power is off. The control system has a control board and a push button switch. It can also be equipped with a wireless remote control according to user needs. Can be equipped with a scrolling display that displays 500 words of display content. It can also be equipped with an intelligent infrared dual-probe anti-collision device, which can automatically return to 20-30CM when encountering people or foreign objects, thereby ensuring the safety of vehicles and pedestrians ^[2]

The shutter door body is made of high-quality stainless steel and other materials. It adopts the parallelogram principle to transfer, which is flexible. The driver is driven by a special motor, the worm and worm gear are decelerated, and a manual clutch is provided, which can be manually opened and closed when the power is off. The rolling door is a telescopic shed type, which has the characteristics of smooth opening and closing, perspective door body, and small space after opening.

1. By setting an intelligent infrared anti-climbing device, the system will alarm immediately when someone climbs the door, thereby ensuring the safety inside the door.

2. Special profiles: Adding different geometric shapes to the high-strength zinc-aluminum alloy profiles can greatly enhance its strength. The surface is treated with special electrophoresis, the gloss is unlimited, it is not easy to stick to dust, it is not corroded by polluted gas, and it will never rust. The new period is long.

3. Engineering plastics: The main plastic parts of the door (such as the connection between the pipe and the pipe, plastic parts, door moving parts, etc.) are made of high-quality engineering plastics (such as PC, PA), which has high toughness, impact resistance, and distortion resistance. Wear-resistant, frost-resistant, light-resistant, not easy to aging, long life, free from wind and snow, lightning, sun and rain.

4. Intelligent infrared probe anti-collision device: the door body can automatically return to operation when it encounters people or foreign objects within 30-50cm, thereby ensuring the safety of vehicles and pedestrians. Standard structure: The interior of the door row (that is, the distance between the two curved main pipes facing each other, excluding the main pipe size) adopts the standard size of the rolling door 320mm (refer to foreign technology) to ensure the most solid cross pipe and greatly reduce the operating noise.

5. The main frame profile of the door body is made of plastic parts with a unique process. The recessed design of the screws at the connection position is used to improve the appearance of the door body. The connection between the profile and the plastic parts is made by punching, pressing, drilling, etc. Make the door body structure firm without solder joints. Cross connection design: The cross pipe is punched by a special process and equipped with a super PA wear-resistant sleeve. The tight combination with the round pipe not only makes the door bar structure stronger, but also ensures smoother operation.

6. The characteristics of the rolling door beautify the environment, improve the appearance of the enterprise, and enhance the corporate image; help to create a civilized enterprise, a civilized factory, and a civilized city atmosphere; improve the security, even if there is damage or overturning in the middle of the night, immediately report to the police. Roller shutter doors are mainly used in living quarters, institutions, schools, enterprises and institutions ^[2]

Inspection and maintenance items

Inspection and maintenance access; inspection and maintenance of the main and auxiliary shafts; inspection and maintenance of the door body.
Inspection methods and requirements

1. The inspectors should be composed of professionals. The inspection work must be inspected by experienced and professional technicians who are familiar with subway conditions.
2. Inspection can be performed by sight, ear, and hand touch, supplemented by corresponding tools and instruments.
3. Ordinary rolling door, fire-proof rolling door, industrial lifting door, electric retractable door, sliding gate, electric induction door must undergo overall operation, inspection and commissioning after each sub-item inspection.
4. After the on-site inspection is completed, the personnel and tools must be cleared and the corresponding inspection and implementation records must be made.
5. On-site inspection and maintenance records must be arranged in time and registered in the daily inspection and maintenance account ^[3]

1. In the selection of materials, more consideration should be given to lightweight, sturdy and durable materials, so that it can play a higher safety problem even in special situations.

2. The purchase of roller shutter motor is also a relatively important part. Remember not to feel that the lifting force is sufficient, because the bearing capacity of the roller shutter motor will gradually reduce the actual lifting effect over time. More than the actual lifting force of the curtain.

3. Observe whether the structure of the electric rolling door is precise, the degree of lubrication is good or bad, and compare the heat dissipation of a good electric rolling door. It adopts full gear rotation, no chain and no belt, thereby enhancing the overall life of the rolling door movement.

4. Brand is also an indispensable factor. In order to reduce production costs, many small processing plants blindly reduce the material quality of accessories. At the same time of installation, the quality cannot be guaranteed, and maintenance is also the same. Therefore, customers should properly consider the brand of the company when purchasing rolling shutters ^{[1 ]}

1. When the shutter door is opened and closed, check whether there are any piles, especially the fire shutter door is linked with the fire protection system. The fire shutter door is often damaged or tilted due to improper operation.

2. Ordinary electric rolling shutter doors should also pay special attention. The curtains should be on the scene when they are opened and closed. In the event of curtain tilting or track jamming, the curtain opening and closing should be stopped in time, so as not to cause greater damage to the motor and curtain. hurt.

2. When the curtain is opened and closed, pedestrians and running are strictly prohibited, because when the curtain is opened and closed, the curtain is connected by a link, and the motor and the transmission shaft also have very few unsafe factors. Therefore, when the curtain is started, no one should try to run ^[3] .
