AI Technical Summary
The existing fire-proof rolling shutter doors are frequently active in the workshop due to the frequent movement of production and transportation vehicles, which can easily cause door frame collision and squeeze, affecting the normal use of door frame tracks. The anti-impact performance of the protective curtain plate is poor, and additional protection is required.
A folding fire-proof roller shutter door with anti-collision function was designed, using a steel plate protective frame and a curved rubber buffer pad as an outer protective mechanism, equipped with a pressure sensor and an acousto-optical alarm, and using a deployment rod, a movable rod and a driven rod to form a three-dimensional protection. The expansion and closing of the movable rod is driven by the traction motor, and the automatic reset of the protective block is achieved by combining the slider and the fixed spring.
It effectively avoids direct contact and crush damage to the fire-proof roller shutter door frame by the vehicle, provides three-dimensional protection, timely alarm reminders, and protects the passage of the door curtain and the integrity of the track.

The guardrail assembly is adapted to the fire shutter door curtain 102. The steel plate protection frame and the arc-shaped rubber buffer pad are used as a protection mechanism on the outside of the fire shutter door frame to prevent people and vehicles from coming and going from direct contact with the fire shutter door frame and causing damage. For strong squeezing such as forklifts, an audible and visual alarm will also be used to warn. Further, a movable protection block is used to close and protect the track of the fire shutter door frame, thereby avoiding damage to the interior without affecting the passage of the fire shutter door curtain.

[0032] Working principle of this utility model:
[0033] When using the device, the fire shutter door curtain 102 is released from the fire shutter door storage compartment 101 to achieve the closing of the fire shutter door. When the fire shutter door curtain 102 is active, it will squeeze the rounded corners on the movable protective block 202, thereby pushing the movable protective block 202 to the side, so that the fire shutter door curtain 102 squeezes the movable protective block 202 open. When the movable protective block 202 is squeezed, it will drive the slider 205 to slide in the slide groove 204. The sliding slider 205 is restricted by the limit slide groove 207 and the limit slider 208, thereby ensuring the movable The fire shutter door frame 100 is stable and does not deviate. At the same time, the slider 205 is movable and compresses the fixed spring 206. When the fire shutter door curtain 102 leaves, the fixed spring 206 pushes the slider 205 and the movable protective block 202 back to their original positions, so that the movable protective block 202 is used to close the track of the fire shutter door frame 100 to avoid damage to the interior without affecting the passage of the fire shutter door curtain 102. For the outside of the fire shutter door frame 100, the steel plate protective frame 200 and the curved rubber buffer pad 201 are used to close the fire shutter door frame 100. The outer side serves as a protection mechanism to prevent people and vehicles from coming and going from direct contact with the fire shutter door frame 100 and causing damage. For strong squeezing by forklifts, an audible and visual alarm 203 will be used to warn. For the protection of the fire shutter door curtain 102, the deployment rod 300, the movable rod 301, and the driven rod 302 are used to form a three-dimensional protection on both sides of the fire shutter door curtain 102. When the fire shutter door curtain 102 is closed, it can be used as a measure to prevent direct impact on the fire shutter door curtain 102, further providing anti-collision protection for the fire shutter door. The two ends of the opening rod 300 realize the expansion of the expansion rod 300 and the movable rod 301 through the rotating hole 303 and the rotating shaft 304, while the driven rod 302 realizes the effect of synchronous movement through the connecting hole 305 and the connecting shaft 306. The movement of the movable rod 301 is driven by the traction motor 401 inside the traction box 400 through the traction rope 403. The rotation of the traction motor 401 can be controlled to control the expansion and closing of the movable rod 301. The bottom side of the movable rod 301 is at a lower position, and a fixed groove can be set. After connection, the supporting and protective effect of the movable rod 301 can be further enhanced.
[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
