Kunming Haydun automatic door responds to public opinion doubts that no torsion spring is a \”guillotine\” Design

Recently, after the torsion spring-free industrial electric lifting door installed in a medical industrial park in Kunming Haydun Garage Door was installed, a promotional video was posted online, attracting widespread attention. Time has become a hot topic among peers. However, some netizens questioned that electric doors without torsion springs may cause the risk of being directly smashed down during a power outage, just like a motor without a mechanical emergency stop device will become a \”guillotine\”. Therefore, netizens are worried that \”there is no torsion spring and it is not safe enough.\”

In response to this, the heads of the sales department, engineering department, production department, R&D department and other departments of Kunming Haidun Door Industry have responded to the safety performance of torsion spring-free electric doors. The more representative views are as follows: First, the torsion spring electric door has multiple safety protection functions, such as the motor\’sIn terms of design, the motor with a torsion spring uses a clutch switching method. If you need to open the door manually during a power outage, you only need to release the clutch to lift the door panel. The motor of the electric door without a torsion spring has its own braking function and physical Anti-fall design, the door panel will immediately be in a stationary running state during a power outage and will not fall directly. The weight of the door panel is borne by the steel rope and motor bearings. In addition, the steel rope adopts an anti-break and anti-fall bracket design, and there is an airbag design at the bottom. , the security performance is comparable to or even surpasses that of anti-theft doors.

In addition, Mr. Wang, the head of the Engineering Department and R&D Department, revealed that the electric door torsion spring motor is the latest \”patented product\” developed by Haydn this year. It is currently in the registration stage. More than 50 of the pharmaceutical industrial park\’s The torsion spring-free industrial lifting door is only in small-scale trial operation. After the operation is stable, whether it is a smart electric garage door or an industrial lifting door, a sliding door, a sliding door, or a folding door, the torsion spring-free motor design can be used, which is very important for electric For the door industry, it is undoubtedly the leading technology level.

Mr. Wang also introduced that there is no need to question the safety performance of these torsion spring-free industrial lifting doors, let alone what they are called \”guillotines\”. First of all, this is a patented product of Haydn Company, and the patented design Including the following five aspects:

First, the motor replaces the chain drive with a special gearbox structure. This is similar to using a high-power turbine motor for the motor of an industrial lifting door. If you need to open the door manually during a power outage, you only need to use a roller shutter. The door can be opened and closed normally by pulling the chain like a door.

Second, the motor brake adopts the elevator protection principle, that is, in the event of an emergency, the anti-fall protection mechanism will be instantly triggered. When the brake fails, the protection mechanism will automatically start, and the automatic door closing speed will be strictly controlled.Controlling the speed within 15-20 seconds per meter, similar to the speed of an escalator, can completely avoid accidents involving injuries.

Third, many industrial lifting doors are designed to lift vertically. If the steel rope suddenly breaks, the entire door leaf may fall vertically, causing the risk of a \”guillotine\”. In order to prevent similar safety accidents, Haydn Door Industry Bottom bracket for electric door without torsion spring It adopts an anti-fall bracket design like a gate blade. When the door leaf loses balance and falls instantly, the gate blade of the bottom bracket is locked and stuck on the track like a car brake pad. The gate blade may even cut directly into the inside of the track until the door panel falls. be stopped, completely preventing the risk of the door panel from falling down. This step is a very critical design, just like a car driving on the highway that loses control of its brakes and rushes directly into the gravel buffer zone designed on the slope the next second.

Fourth, from the perspective of the number of motor operations of the torsion spring-free electric door, or the service life of the motor, the number of times this high-power motor is used exclusively developed and designed by Kunming Haidun Door Industry Greater than 50,000 times. After running the test once every minute, after practicing repeatedly for about a year, there has never been an incident such as instantaneous jamming or poor operation caused by the motor overheating protection of the roller shutter door, nor has there been any power outage during operation. Testing the natural fall situation, the actual operation reached the standard more than 70,000 times, achieving perfect experimental results with zero failures. What does this result mean? Calculated based on the normal operation of 10 times a day, it will take about 10 years to complete the normal operation of the motor about 50,000 times.

Fifth, in accordance with the design concept of Kunming Haydn R&D Department’s pursuit of excellence, the experiment of long-term operation of torsion spring-free electric doors will not stop in the short term and will continue for a long time. The next step is to extend the service life of the motor to more than 20 years, which means that the motor can be used more than 100,000 times.

Generally speaking, the torsion spring motor design of Kunming Haydun automatic door not only considers the motor gear design, the running speed under power outage, the use of slow motion to strictly guard the safety door, the emergency stop anti-fall design, and the long-term operation zero Faults and other multiple angles responded to the doubts of online public opinion, and also reflected the scientific and rigorous professional attitude of Haydn Door Industry in handling problems.
