Abstract
Description
Technical Field
[0001] This utility model relates to the field of roller shutter door technology, and in particular to a quick-opening and closing roller shutter door installation structure. Background Technology
[0002] High-speed rolling doors refer to doors with an operating speed exceeding 0.6 meters per second. They are fast-lifting, barrier-free isolation doors primarily used for rapid isolation to maintain the cleanliness level of the workshop air. They offer multiple functions including heat insulation, cold insulation, insect prevention, windproofing, dustproofing, sound insulation, fireproofing, odor prevention, and light transmission. Widely used in food, chemical, textile, electronics, supermarket, cold storage, logistics, and warehousing industries, they highly meet the needs of high-performance logistics and clean environments, while also saving energy, automatically closing at high speed, improving operational efficiency, and creating a better working environment.
[0003] However, in some workshops with high cleanroom requirements, forklifts are frequently used, resulting in slow opening and closing speeds, making ordinary high-speed rolling doors unsuitable for the workshop's needs. Utility Model Content
[0004] The purpose of this invention is to provide a quick-opening and closing roller shutter door installation structure to solve the problems existing in the prior art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A quick-opening and closing roller shutter door installation structure includes a doorway, a curtain, a first guide rail, a second guide rail, and a magnetic coil. The doorway is located on the front side of the workshop wall. The first guide rail is fixedly installed on the left side of the doorway, and the second guide rail is fixedly installed on the right side of the doorway. A housing is fixedly installed on the top of the doorway. A drive device is located on the left side of the housing, and a guide plate is rotatably installed on the right side of the drive device. The top left side of the curtain is fixedly connected to the right side of the guide plate. The bottom left side of the curtain is slidably installed on the right side of the first quick-opening guide rail, and the bottom right side of the curtain is slidably installed on the left side of the second quick-opening guide rail. An air curtain is fixedly installed on the front side of the housing. The magnetic coils are spaced apart on the top of the ground in front of the doorway.
[0007] By adopting the above technical solution, the geomagnetic coil can react quickly when a vehicle or metal object approaches the high-speed rolling door, causing the servo motor in the drive unit to quickly drive the guide plate and roll the curtain to the upper and lower positions to allow vehicle passage. During the curtain's ascent, the air curtain will open, forming an air wall to prevent dust or other impurities from entering the workshop. After the vehicle passes, the air curtain will close as the curtain closes. At this time, the air quality in the workshop still meets the cleanroom requirements and will not be significantly affected by the external environment. The guide plate is equipped with a silent track to accommodate the fixing device on one side of the curtain. Because the curtain is lightweight, the rolling can be completed by the guide plate and servo motor without the need for additional rollers, effectively improving the opening and closing speed and ensuring the cleanroom's cleanroom level.
[0008] In a further embodiment, a light curtain transmitter is fixedly installed on the right side of the first guide rail, a light curtain receiver is fixedly installed on the left side of the second guide rail, and multiple buffer airbags are fixedly installed at the bottom of the curtain.
[0009] By adopting the above technical solution, the light curtain transmitter and light curtain receiver can form a safety net with a lower possibility of failure. Compared with the traditional method of relying on linear infrared sensors to detect whether people or objects are passing by, it is more reliable and can effectively increase the probability of detection. This ensures that the rapidly descending roller shutter will not injure passing personnel and equipment during the descent. At the same time, the buffer airbag also provides a final layer of protection for the curtain. Due to the curtain itself, the safety is effectively improved.
[0010] In a further embodiment, a control terminal is fixedly installed at the middle position of the front side of the first guide rail. A touch screen is provided at the top front side of the control terminal, and a start button, a stop button, and an emergency stop button are provided at the bottom front side of the control terminal.
[0011] By adopting the above technical solution, the touch screen on the control terminal is password protected to prevent unauthorized personnel from arbitrarily adjusting it, which could cause unnecessary trouble or accidents. After entering the password through the touch screen, the speed of the air curtain machine and the upper and lower limits of the curtain can be adjusted separately. At the same time, the emergency stop button can effectively prevent situations where there are no emergency measures in case of an accident. When personnel pass through, they only need to press the up button. When the safety light curtain detects that personnel have passed through, the control terminal starts a timer. If no subsequent personnel pass through within six seconds, the curtain will lower and the air curtain machine will close. The entire adjustment process is very flexible and effective.
[0012] In a further embodiment, a first anti-collision bar is fixedly installed on the front side of the first guide rail, and a second anti-collision bar is fixedly installed on the front side of the second guide rail. Dust covers are fixedly installed on the top of both the first and second anti-collision bars.
[0013] Even with the above technical solutions, the anti-collision bars still prevent collisions that may occur when forklifts need to reverse into the vehicle or turn when fully loaded. Since the entire roller shutter door is made of an aluminum alloy frame, it is relatively easy to be shaken. Furthermore, the curtain is a lightweight material that is easily damaged in an impact, and replacement is very troublesome, requiring a lot of manpower and resources. It may also affect the air quality in the workshop, causing further production problems.
[0014] In a further embodiment, an audible and visual alarm device is fixedly installed on the upper right side of the second guide rail, and the audible and visual alarm device is electrically connected to the control terminal via a wire.
[0015] By adopting the above technical solution, the audible and visual alarm device can inform passersby of the working status of the roller shutter door, including whether it is open or closed, which has a certain warning effect on passersby. When a fire or other alarm occurs, the audible and visual alarm device can also transmit an alarm signal.
[0016] In a further embodiment, a transparent observation strip is provided in the middle of the curtain.
[0017] By adopting the above technical solution, the transparent observation strip helps to observe the scene on the other side of the curtain, so as to avoid excessive noise in the workshop and the inability to detect forklifts and other vehicles that are about to leave the curtain.
[0018] In summary, this utility model has the following beneficial effects:
[0019] 1. By using an air curtain machine and a geomagnetic coil, when a forklift or other metal vehicle approaches the high-speed rolling door, the curtain is immediately driven by the servo motor in the drive unit, which quickly rolls the curtain along the guide wheels to make way for the forklift. At the same time, an important function of the high-speed rolling door is to isolate dust inside and outside the factory, thereby ensuring that the air inside the factory is kept at an acceptable dust-free level. In addition to the fast-opening and closing curtain, the air curtain machine can also be opened when the curtain is moving and closed accordingly when the curtain is closing, so as to achieve the effect of fast opening and closing of the rolling door while avoiding dust pollution of the internal air.
[0020] 2. By using a light curtain emitter and an airbag, the light curtain can prevent accidents caused to people or vehicles passing by during its descent when the curtain closes too quickly. If the light curtain malfunctions or does not react in time, the airbag can also cushion the impact.
[0021] 3. By setting up audible and visual alarm devices and transparent observation strips, the operating status of high-speed rolling doors can be made clearer and more transparent, making it easier for employees to understand the safety status of the internal and external factory buildings and to determine whether immediate evacuation is necessary, thus effectively improving production safety.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.
[0025] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to the attached figures. Figure 1 In this specification, the terms "bottom surface" and "top surface," "inner" and "outer" refer to the direction toward or away from the geometry of a specific component. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this specification, "a plurality of" means two or more, unless otherwise explicitly and specifically defined by the direction of the center.
[0026] Example 1: As Figure 1As shown, a quick-opening and closing roller shutter installation structure includes a door opening, a curtain 1, a first guide rail 2, a second guide rail 3, and a ground magnetic coil 4. The door opening is located on the front side of the workshop wall. The first guide rail 2 is fixedly installed on the left side of the door opening, and the second guide rail 3 is fixedly installed on the right side of the door opening. A housing 5 is fixedly installed at the top of the door opening. A drive device 6 is located on the left side of the housing 5, and a guide plate 7 is rotatably installed on the right side of the drive device 6. The top left side of the curtain 1 is fixedly connected to the right side of the guide plate 7, and the bottom left side of the curtain 1 is slidably installed on the first quick-opening and closing roller shutter door. On the right side of the guide rail, the bottom right side of the curtain 1 is slidably mounted on the left side of the second fast guide rail. A transparent observation strip is set in the middle of the curtain 1. An air curtain machine 8 is fixedly mounted on the front side of the housing 5. Magnetic coils 4 are spaced apart on the top of the ground in front of the doorway. A light curtain transmitter 9 is fixedly mounted on the right side of the first guide rail 2. A light curtain receiver 10 is fixedly mounted on the left side of the second guide rail 3. Multiple buffer airbags 11 are fixedly mounted at the bottom of the curtain 1. An audible and visual alarm device 16 is fixedly mounted on the upper right side of the second guide rail 3. The device and control terminal 12 are electrically connected via wires. Through the geomagnetic coil 4 and the curtain 1, the servo motor in the drive device 6 can start immediately after sensing that a vehicle is approaching in front of the curtain 1, and roll up the curtain 1 through the guide plate 7. The light curtain transmitter 9 and the light curtain receiver 10 can form a safety light curtain in front of the curtain 1, thereby ensuring that people or objects will not be hit on the head by the rapidly falling curtain 1 when passing through the roller shutter door. The buffer airbag 11 can further reduce the damage caused by the collision, while the transparent observation strip makes it convenient for employees inside and outside the workshop to observe whether there is a vehicle on the other side of the curtain 1, so that they can avoid it in time and avoid the danger caused by the noise environment inside the workshop not being able to identify the vehicle outside in time. In addition to the rapidly rising and falling curtain 1, there is also an air curtain machine 8, which will start synchronously when the curtain 1 rises and stop synchronously when the curtain 1 closes. The air curtain machine 8 can form an air wall to block the air inside and outside the workshop from flowing during the short gap when the door is opened, thereby further ensuring the cleanroom quality level of the workshop.
[0027] like Figure 1As shown, a control terminal 12 is fixedly installed at the middle of the front side of the first guide rail 2. A touch screen is provided at the top front of the control terminal 12, and a start button, a stop button, and an emergency stop button are provided at the bottom front of the control terminal 12. The light curtain transmitter 9 and the light curtain receiver 10 are both electrically connected to the control terminal 12. A first anti-collision bar 13 is fixedly installed on the front side of the first guide rail 2, and a second anti-collision bar 14 is fixedly installed on the front side of the second guide rail 3. Dust covers 15 are fixedly installed on the top of both the first anti-collision bar 13 and the second anti-collision bar 14. Through the control terminal 12, the speed, limit, and strength of the air curtain machine 8 of the curtain 1 can be easily adjusted. After the safety light curtain detects an object passing through when the curtain 1 is closed, the operation of the drive device 6 is immediately stopped to prevent the curtain 1 from continuing to fall at high speed. The first anti-collision bar 13 and the second anti-collision bar 14 are mainly used to deal with special vehicles such as forklifts in the factory to avoid collisions with the curtain 1 when they cannot be properly watched, thus preventing damage to the curtain 1.
[0028] Specific implementation process: Curtain 1 is normally closed. When someone presses the rise button on the control terminal 12, or when the geomagnetic coil 4 senses that a vehicle or other metal object is about to pass, curtain 1 will automatically rise, connecting the inside and outside of the workshop. During this process, the air curtain machine 8 will start operating, creating an air wall that prevents dust containing air from entering. At the same time, the control terminal 12 will start timing. If no object is detected passing through the safety light curtain within six seconds, curtain 1 will quickly descend, closing the inside and outside of the workshop again.
