Description

Technical Field

[0001] This utility model relates to a fireproof roller shutter system, specifically to a split-type extended frame plate double-track double-link roller shutter system device. Background Technology

[0002] The double-track, double-panel roller shutter system is a special type of fire-resistant roller shutter system, primarily used in locations requiring a large span. It achieves more efficient fire separation and space utilization through the coordinated operation of two independent tracks and two roller shutter doors (curtains). The two roller shutter doors in the system are synchronously raised and lowered via a linkage mechanism. Existing double-track, double-panel roller shutter systems employ an integrated structure, where a single motor drives the raising and lowering of both roller shutter doors within a single structural component. This structure is highly suitable for systems with both tracks on the same side, but it is often unsuitable when the tracks are on opposite sides of a wall, especially on thick walls. Summary of the Invention

Detailed Implementation

[0018] Referring to the accompanying drawings, a split-type extended frame plate double-track double-link roller shutter system includes a first split B1 and a second split B2 located on both sides of a wall structural beam A; a first frame plate 6 is provided on the first split B1, and a first roller 2a is arranged on the first frame plate 6; a second frame plate 7 is provided on the second split B2, and a second roller 2b is arranged on the second frame plate 7; the first roller 2a and the second roller 2b are connected to a double-link chain 14, and a fireproof roller shutter motor 4 and the double-link chain are provided on one side of the double-link chain 14. On the other side of 14, a tensioning guide wheel 1 is provided. The fireproof rolling shutter is driven by the rotating door motor 4 to rotate the double chain 14, and the double chain 14 drives the first roller 2a and the second roller 2b to rotate synchronously. The upper part of the wall structure beam A is provided with an upper through hole 10a for the upper section of the double chain 14 to pass through, and the lower part of the wall structure beam A is provided with a lower through hole 10b for the lower section of the double chain 14 to pass through. The inner side of the first frame plate 6 is fixedly connected to the wall structure beam A, and the inner side of the second frame plate 7 is fixedly connected to the wall structure beam A.

[0019] In the diagram, the first component B1 and the second component B2 are respectively installed on both sides of the wall structure beam A. The position shown for the roller 2 (including the first roller 2a and the second roller 2b) is a large gear, and the position shown for the fireproof roller shutter motor 4 is a small gear at the output shaft end. The double chain 14 is a chain that matches the gears of the roller 2 and the fireproof roller shutter motor 4. A tension guide wheel 1 is installed on the other side of the double chain 14 to pull it open. This tension guide wheel 1 can be a gear or other roller. The guide wheel assembly ensures the rotation direction of the first roller 2a and the second roller 2b, satisfying the synchronous lifting or lowering of the double curtains. During installation, holes are drilled in the wall structure beam A at the pre-drilled positions of the double chain 14. This allows the fireproof roller shutter motor 4 to rotate, driving the double chain 14 to rotate, which in turn drives the first roller 2a and the second roller 2b to rotate synchronously, thus completing the synchronous lifting and lowering of the double-track double roller shutter. This utility model is applicable to situations where double tracks are on both sides of a thick wall. It is easy to install and can further reduce the space occupied by the roller shutter box. It is very useful for places with large spans or limited space.

[0020] Furthermore, the fireproof rolling shutter door motor 4 is located on the outside of the first frame plate 6, the first roller 2a is located on the inside of the double chain 14, and the second roller 2b is located on the outside of the double chain 14.

[0021] Referring to the attached diagram, the arrangement of the double chain 14 enables the first scroll 2a and the second scroll 2 to rotate in the same direction, that is, to rotate synchronously clockwise or synchronously counterclockwise, thereby achieving synchronous rotation.

[0022] Furthermore, an embodiment is provided; the upper through hole 10a and the lower through hole 10b are the same hole. That is, a hole can be made in the structural beam A of the wall, and the upper and lower sections of the double chain 14 can pass through this hole to enable the double chain 14 to drive the first roller 2a and the second roller 2 to rotate synchronously. However, this solution requires that tensioning guide wheels 1 be provided at the upper and lower positions on the inner and outer sides of the hole to ensure that the hole wall does not interfere with the double chain 14.

[0023] Furthermore, referring to the accompanying drawings, the first spool 2a and the second spool 2b are the same standard part. The upper through hole 10a is located on the connecting line of the upper edge of the first spool 2a and the second spool 2b, and the lower through hole 10b is located on the connecting line of the lower edge of the first spool 2a and the second spool 2b. Tensioning guide wheels 1 are provided on the side of the upper through hole 10a and / or the lower through hole 10b.

[0024] With the upper perforation 10a and lower perforation 10b in this way, the double chain 14 rotates more smoothly, and the fireproof rolling shutter roller door motor 4 operates more energy-efficiently.

[0025] Furthermore, a tensioning guide wheel 1 is installed on the outer side of the second frame plate 7. (Refer to...) Figure 3 The second embodiment of this utility model: a set of tensioning guide wheels 1 are provided on the outer side of the second frame plate 7. This is the basic embodiment, which ensures that the double chain 14 is tensioned, thereby driving the first roller 2a and the second roller 2b to rotate synchronously.

[0026] Reference Figure 2 In the first embodiment of this utility model, tension guide wheels 1 are provided on both the upper and lower sides of the outer side of the second frame plate 7. That is, multiple sets of tension guide wheels 1 are provided on the outer side of the second frame plate 7. In the figure, two sets of tension guide wheels 1 are provided on the upper and lower sides of the outer side of the second reel 2b, so that the contact surface between the double chain 14 and the outer side of the second reel 2b is longer, and the execution effect is more stable.

[0027] Furthermore, the curtain fabric of the roller blind is an inorganic composite curtain surface 11, which has four layers: fiberglass decorative fabric 16, fireproof fabric 17, aluminum silicate spun fireproof blanket 18, and radiation-proof fabric 19. The four-layer structure of the inorganic composite curtain surface 11 is fixedly connected by curtain bolt assembly 13 and molded clamping plate 15 with windproof hooks. This configuration of the inorganic composite curtain surface 11 provides better fire resistance.

[0028] Furthermore, an emergency opening and closing chain 20 for the fireproof rolling shutter is also installed on the side of the rolling door motor 4. This facilitates manual lifting and lowering of the inorganic composite curtain 11 in the system.
