Description

Technical Field

[0001] The invention relates to the technical field of rolling shutter doors, in particular to an inorganic heat-insulating double-width fireproof rolling shutter with a movable steel frame for compression resistance and automatic leveling. Background Art

[0002] The fireproof roller shutter is a fireproof and heat-insulating facility suitable for larger openings in buildings. The curtain surface of the fireproof roller shutter is raised and lowered through a transmission device and a control system, which plays a role in heat insulation and fire isolation, and can effectively prevent the spread of fire and protect life and property. Among them, the main structure of the fireproof roller shutter includes a reel, a fireproof curtain surface fixed on the reel at one end, and two sets of guide rails fixed on the door opening. A rolling door machine for the fireproof roller shutter is fixed to one end of the reel, and the rolling door machine drives the reel to rotate, thereby driving the fireproof curtain surface to be rolled up and unrolled.

[0003] Most of the existing fireproof roller shutters are inorganic flexible curtain surfaces, which have poor wind and bending resistance. When the roller shutters encounter strong winds or positive or negative pressure conditions caused by fire, the curtain surfaces lack sufficient supporting structures, which can easily cause the two curtain surfaces to stick together, resulting in reduced thermal insulation performance of the fireproof roller shutters and loss of their thermal insulation significance. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides an inorganic heat-insulating double-width fireproof rolling shutter with a movable steel frame for compression resistance and automatic leveling. It is designed to solve the problems in the background technology by providing a double-layer rolling shutter door structure and an anti-bending and compression device between the double-layer rolling shutter doors for support.

[0005] In order to achieve the above technical objectives, the specific technical scheme of the present invention is as follows: the present invention proposes an inorganic heat-insulating double-width fireproof rolling shutter with a movable steel frame for compression resistance and automatic leveling, comprising: two fireproof rolling shutter curtain surfaces and two rolling tubes for driving the fireproof rolling shutter curtain surfaces to be rolled up one by one, and the rolling tubes are coaxially fixedly connected with a rolling shaft; a fireproof cover, which is installed on the periphery of the rolling tube and the rolling door frame; a motor frame, on which a rolling door machine for the fireproof rolling shutter is installed, which is used to drive the two rolling tubes to rotate in the same direction; a guide rail, which cooperates with the lifting and lowering of the fireproof rolling shutter surface, and the end of the fireproof rolling shutter surface is fixedly connected to a base frame, and the base frame is slidably connected to the guide rail; an anti-bending and anti-compression device, which is arranged between the two fireproof rolling shutter curtain surfaces, and the anti-bending and anti-compression device includes a movable steel frame for supporting the inner side of the fireproof rolling shutter curtain surface, wherein a plurality of movable steel frames are provided and distributed in upper and lower layers; adjacent movable steel frames are connected by steel wire ropes, and the position of the uppermost movable steel frame is fixed, so that the movable steel frame can automatically unfold and retract with the lifting and lowering of the fireproof rolling shutter curtain surface.

[0006] As a preferred technical solution of the present invention, the bottommost movable steel frame is fixedly connected to a connecting plate that cooperates with the base frame, and a plurality of leveling mechanisms are installed on the connecting plate. The leveling mechanism includes a screw rod, which is movably connected to the base frame, and a cylindrical spring is sleeved on the surface of the screw rod, and a limiting nut is fixedly connected to the top of the screw rod.

[0007] As a preferred technical solution of the present invention, a pair of movable support frames are symmetrically connected on both sides of the movable steel frame, which are used to support the inner side of the fireproof rolling shutter curtain surface, and a liftable movable frame is connected above the movable steel frame, the lower end of the steel wire rope is fixedly connected to the movable steel frame, the upper end of the steel wire rope is fixedly connected to the movable frame, and the lowest mobile frame is fixedly connected to a plurality of automatic leveling connecting frames.

[0008] As a preferred technical solution of the present invention, a sliding rod is fixedly connected to the support frame, the sliding rod is movably connected to the movable steel frame, and a slider is slidably connected to the sliding rod. A first connecting rod is rotatably connected between the slider and the movable frame, and a first spring is sleeved on the surface of the sliding rod, and the first spring is arranged between the slider and the support frame.

[0009] As a preferred technical solution of the present invention, a support plate is rotatably connected to the support frame, a second connecting rod is rotatably connected between the support plate and the sliding block, a stopper is fixedly connected to one end of the sliding block, and a second spring is fixedly connected between the stopper and the movable steel frame.

[0010] The beneficial effects of the present invention are:

[0011] 1. The present invention provides an anti-bending and anti-compression device between the double-layer fireproof rolling shutter curtain surfaces. The anti-bending and anti-compression device includes a plurality of movable steel frames that can be unfolded and folded. When the rolling shutter door descends, the movable steel frames are driven to unfold, thereby being able to evenly support various positions of the rolling shutter door curtain surface, thereby improving the wind resistance and pressure resistance of the fireproof rolling shutter and enhancing the heat insulation performance of the fireproof rolling shutter.

[0012] 2. The present invention connects a supporting frame and a moving frame to a movable steel frame.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Embodiment 1: This embodiment discloses an inorganic heat-insulating double-width fireproof roller shutter with a movable steel frame for compression resistance and automatic leveling, such as Figure 1-Figure 7As shown, it includes: two fireproof rolling shutter curtain surfaces 1 and two rolling tubes 2 for driving the fireproof rolling shutter curtain surfaces 1 to be rolled up one by one, and the rolling tubes 2 are coaxially fixedly connected with a rolling shaft 21; a fireproof cover 7, which is installed on the periphery of the rolling tube 2 and the motor frame 5; the motor frame 5, on which a rolling door machine 6 for fireproof rolling shutter is installed, which is used to drive the two rolling tubes 2 to rotate in the same direction, and the rolling door machine 6 for fireproof rolling shutter only needs to be provided with one, and the rolling door machine 6 for fireproof rolling shutter drives the two rolling shafts 21 to rotate in the same direction through a sprocket and a chain; a guide rail 8, which cooperates with the lifting and lowering of the fireproof rolling shutter curtain surface 1, and each fireproof rolling shutter curtain surface 1 is equipped with two guide rails 8, and the end of the fireproof rolling shutter curtain surface 1 is fixedly connected with a base frame 9, and the base frame 9 is an L-shaped structure, and the base frame 9 is slidably connected to the guide rail 8; an anti-bending and anti-compression device 4 is arranged between the two fireproof rolling shutter curtain surfaces 1, and is used to support the fireproof rolling shutter curtain surface 1 to improve the anti-bending and anti-compression performance of the fireproof rolling shutter curtain surface 1.

[0024] like Figure 2 As shown, the anti-bending and anti-compression device 4 includes a movable steel frame 41, which is a rectangular frame structure, wherein a plurality of movable steel frames 41 are provided and distributed in upper and lower layers, and the movable steel frames 41 are used to support the inner side of the fireproof rolling shutter curtain surface 1, and the movable steel frames 41 can automatically unfold and fold as the fireproof rolling shutter curtain surface 1 is raised or lowered; wherein, the position of the uppermost movable steel frame 41 is fixed, and the position of the uppermost movable steel frame 41 remains unchanged when the fireproof rolling shutter curtain surface 1 is raised or lowered; adjacent movable steel frames 41 are connected by four steel wire ropes 42, and when the fireproof rolling shutter curtain surface 1 rises, the movable steel frames 41 can be driven to be folded and stacked together from bottom to top in sequence; when the fireproof rolling shutter curtain surface 1 descends, the movable steel frames 41 can be driven to be evenly unfolded from top to bottom in sequence, thereby supporting different positions of the fireproof rolling shutter curtain surface 1, and improving the wind resistance and bending resistance of the fireproof rolling shutter curtain surface 1.

[0025] like Figure 3 As shown, the bottommost movable steel frame 41 is fixedly connected with a connecting plate 3 that cooperates with the base frame 9. The connecting plate 3 is arranged below the base frame 9. A plurality of leveling mechanisms are installed on the connecting plate 3 for leveling the fireproof roller shutter curtain surface 1, wherein the leveling mechanism includes a screw 10, which is movably connected to the base frame 9, and a cylindrical spring 11 is sleeved on the surface of the screw 10, and a limiting nut 12 is fixedly connected to the top of the screw 10; when the fireproof roller shutter curtain surface 1 rises to the highest point, the movable steel frames 41 are stored and stacked together, and the base frame 9 is compressed upward by the cylindrical spring 11, so that the fireproof roller shutter curtain surface 1 rises to different heights while the base frame 9 can remain horizontal, thereby playing a leveling role to prevent the lower end base from being uneven after the fireproof roller shutter curtain surface 1 is rolled up.

[0026] Embodiment 2: Based on the structure of the above embodiment 1, the difference is that Figure 4-Figure 6As shown, the width of the movable steel frame 41 of this embodiment is smaller than the distance between the two fireproof roller shutter curtain surfaces 1, wherein a pair of movable support frames 45 are symmetrically connected to the two sides of the movable steel frame 41 for supporting the inner side of the fireproof roller shutter curtain surface 1, and a liftable movable frame 43 is connected above the movable steel frame 41, wherein the lower end of the steel wire rope 42 is fixedly connected to the movable steel frame 41 of the lower layer, and the upper end of the steel wire rope 42 is fixedly connected to the movable frame 43 of the upper layer, and the movable frame 43 of the lowest layer is fixedly connected to a connecting frame 44, and the connecting frame 44 is fixedly connected to the connecting plate 3.

[0027] like Figure 7 As shown, a pair of slide bars 49 are symmetrically fixedly connected to the support frame 45, and the number of slide bars 49 is four and symmetrically arranged about the movable steel frame 41, wherein the slide bars 49 are movably connected to the movable steel frame 41, and a slider 48 is slidably connected to the slide bars 49, and a first connecting rod 47 is rotatably connected between the slider 48 and the movable frame 43, and a first spring 411 is sleeved on the surface of the slide bar 49, and the first spring 411 is arranged between the slider 48 and the support frame 45; a support plate 46 is rotatably connected to the support frame 45, and the support plate 46 is connected to the slide bar 49. A second connecting rod 410 is rotatably connected between the blocks 48, and when the support plate 46 is rotated to a vertical state, it contacts the surface of the fireproof rolling curtain 1, and one end of the sliding rod 49 is fixedly connected to a stopper 412, and a second spring 413 is fixedly connected between the stopper 412 and the movable steel frame 41, and the elastic coefficient of the second spring 413 is smaller than the elastic coefficient of the first spring 411; when the fireproof rolling curtain 1 descends, the movable steel frame 41 is driven to unfold in sequence, and after unfolding, when the fireproof rolling curtain 1 continues to descend, the lower layer The movable steel frame 41 will apply a downward pulling force to the upper movable frame 43, and the movable frame 43 descends and moves in the direction close to the movable steel frame 41. During the movement, the slider 48, the slide bar 49 and the support frame 45 are first driven to move outward as a whole, and the second spring 413 is compressed until the support frame 45 contacts the surface of the fireproof rolling shutter curtain surface 1. When the movable frame 43 continues to descend, the slider 48 is driven to slide on the slide bar 49, and then the support plate 46 is driven to rotate outward until the support plate 46 contacts the surface of the fireproof rolling shutter curtain surface 1, and then The supporting area for the fireproof rolling shutter curtain surface 1 is increased to form a stable supporting structure. When the fireproof rolling shutter curtain surface 1 drops to the lowest position, the support plates 46 on each layer of the movable steel frame 41 are in tight contact with the surface of the fireproof rolling shutter curtain surface 1; similarly, when the fireproof rolling shutter curtain surface 1 rises, the support plates 46 and the support frames 45 are first separated from the surface of the fireproof rolling shutter curtain surface 1 and then moved to their original positions, and the movable steel frames 41 then rise in turn, thereby preventing the support plates 46 and the support frames 45 from scratching the fireproof rolling shutter curtain surface 1 during the lifting process of the movable steel frames 41.

[0028] During specific implementation: the fireproof rolling shutter rolling door machine 6 drives the two fireproof rolling shutter curtain surfaces 1 to descend, and when the fireproof rolling shutter curtain surface 1 descends, it drives the movable steel frame 41 to unfold in sequence. When the fireproof rolling shutter curtain surface 1 continues to descend, the movable steel frame 41 of the lower layer will exert a downward pulling force on the movable frame 43 of the upper layer, driving the movable frame 43 to descend and move in the direction close to the movable steel frame 41. During the movement, the slider 48, the slide rod 49 and the support frame 45 are first driven to move outward as a whole, and the second spring 413 is compressed by force until the support frame 45 contacts the surface of the fireproof rolling shutter curtain surface 1. When the movable frame 43 continues to descend, the slider 48 is driven to slide on the slide rod 49, and then the support plate 46 is driven to rotate outward until the support plate 46 contacts the surface of the fireproof rolling shutter curtain surface 1, thereby increasing the support area of ​​the fireproof rolling shutter curtain surface 1 and forming a stable support structure; thereby improving the wind and pressure resistance of the fireproof rolling shutter curtain surface 1, ensuring that the two curtain surfaces maintain a certain distance, and enhancing the fireproof and heat-insulating properties of the fireproof rolling shutter.
