Embodiment 1

[0014] Embodiment 1 As shown in Figures 1 and 2:

[0015] Door rolling machine 10 is arranged, and rolling door machine 10 places in the bag case 7, and the control circuit that door rolling machine 10, bag case 7 and join with rolling door machine 10 is all with prior art. A plurality of steel wire ropes 3 are vertically arranged in double rows, and screws with collars 9 fix a plurality of splints 2 (a pair) arranged at intervals in the transverse direction on the inorganic cloth-based curtain surface 1 with a fireproof interlayer in the middle. Face 1 is placed between splints 2 . The splint 2 at the top is fixedly connected to the bag box 7, the splint 2 at the bottom is fixed to the lower end of the steel wire rope 3 and a bottom plate 5 is connected between the two splints 2, and the collars 9 on the multiple splints 2 in the middle are set on the steel wire rope 3, and the steel wire rope 3 above is connected with the reel 8 of the door rolling machine 10 through the fi...

Embodiment 2

[0016] Embodiment 2 is as shown in Figures 1, 2, 3, and 4:

[0017] Other structures are all the same as in embodiment 1, except that the entire curtain surface is T-shaped, L-shaped or U-shaped, and the shape of the splint 2 can be determined according to the specific shape of the roller blind, and the connection mode of the splint 2 can be as shown in Figure 4. Screws 18 connect the segmented splints 2 . There can be multiple door rolling machines 10, so as to roll the wire ropes 3 on different planes. But the transmission mechanism shown in Figure 3 can also be used, that is, bevel gears 11 are connected to the two ends of the spool 8, the bevel gears 11 are connected to the spool 12 arranged on the bearing 13, and the bevel gear 11, the bearing 13 and the spool 8 connected bearings 15 are arranged on the gear box 16, flange 17 is connected on the end of the reel 12, during installation, the gear box 16 is fixed by the flange 17, and the wire rope 3 is connected with the r...

Embodiment 3

[0018] Embodiment 3 is as shown in Figures 1, 2, 3, and 4:

[0019] Other structures are with embodiment 1 or embodiment 2, and just splint 2, base plate 5 all are the annular of closure, as circle, square etc., because the splint 2 of closure does not have end, so need not guide rail 6.

[0020] work process:

[0021] When there is no fire, the steel wire rope 3 is rolled on the reel 8 of the rolling door machine 10 through the fixed pulley 4, and the bottom splint 2 connected to the lower end of the steel wire rope 3 is lifted along the guide rail 6 with the steel wire rope 3, and the multiple splints 2 in the middle are also lifted along the guide rail 6. The guide rail 6 slides and folds the inorganic cloth-based curtain surface 1. When the bottom splint 2 is lifted below the box 7, the rolling door machine 10 stops; Start, the top splint 2 is fixed, the bottom splint 2 descends along the guide rail 6 with the wire rope 3, the folded inorganic cloth-based curtain surface ...

Abstract

The invention discloses an inorganic cloth-based folded lifting protection roller shade, comprising door-convolving machine (10) set in lodge (7), two-rows steel cable (3) set in vertical, multiple splints (2) transversely set in distance and fixed on inorganic cloth-based shade, top splint (2) is firmly connected with lodge (7), bottom splint is fixed with the bottom end of steel cable and ringer (9) of multiple splints in middle is set on steel cable (3), whose top is connected with roller axis (8) of door-convolving machine, bottom board (5) is set between two splints whose bottom end is connected with steel cable (3). It is applied in various shape hole with big span, L-shape, U-shape and so on.

Description

Technical field: [0001] The present invention relates to a fire-proof roller shutter for separating fire-proof areas, especially an inorganic cloth-based folding and lifting type suitable for large-span and "L"-shaped, "U"-shaped, circular, square and other geometric openings. Fireproof Shutter. Background technique: [0002] At present, the fire shutters used to separate fire protection areas mainly include steel fire shutters and double-track inorganic curtain surface fire shutters. It is fixed on the reel of the rolling door machine, and the curtain surface is rotated by the reel to make the curtain surface rise or fall. However, the above two fire shutters are mainly suitable for the installation of straight-line openings, and cannot be installed at the openings of various geometric shapes such as "L", "U", round, square, etc., and the fire-proof rolls with a straight opening span greater than 20m Curtains are often unable to roll due to the large winding degree of the...
