Abstract
The utility model relates to a folding fire-proof curtain device of the fire fighting device, which comprises a fire-proof curtain, an open-close machine and a transmission system. The transmission system comprises two rollers that are fixed at the front and the back of the fire-proof curtain cloth and are respectively connected with at least two rows of wire cables winding on the rollers; and brackets are hanged at the lower ends of the two rows of wire cables. Moreover, the lower end of the fire-proof curtain cloth is fixed on the bracket, and the upper end of the fire-proof curtain cloth is fixed with a hanging plate which is hanged on the mounting plate that is fixed on the beam by use of the hanging component. The separate two ends of the two rollers are respectively provided with bearings and fixed on the end bearing plates. Compared with the prior art, the folding fire-proof curtain device has such advantages as promising convenient mounting operation and being applicable to large-span fire-proof obstruct.
Description
Technical field the utility model relates to the door leaf of fixed buildings specific use, particularly relates to the fire screen of fire fighting device.
The fire screen of background technology prior art all is that fire screen cloth is wound on the spool, drives spool by headstock gear, thereby makes the fire prevention cord synchronization lifting that is wound on the spool.Adopt the fire screen of this kind technology to have following deficiency: because fire screen cloth is wound on the spool, therefore can not increase supporting-point with load-bearing in the middle of the spool, simultaneously, spool changes together with the lifting with the fire prevention cord of the diameter of fire prevention cord wound thereon, when the fire screen span is very big, can not realize on the engineering at all.
The summary of the invention the purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and proposes a kind of collapsible fire screen device, and this fire screen device can be applicable to that large span fire prevention cuts off, and installs and use all very convenient.
The purpose of this utility model can be by realizing by the following technical solutions:
Design, a kind of collapsible fire screen device of use, comprise fire prevention cord, headstock gear, transmission system, this transmission system comprises two spools that are fixed in fire prevention cord front and back, respectively be connected with can reel thereon steel wire rope of a row who comprises two at least on this two spool, this two is arranged steel wire rope lower end and is hung with carriage;
The lower end of described fire prevention cord is fixed on the described carriage, and its upper end is fixed with link plate, and this link plate is hung on the installing plate that is fixed on the beam by suspender member.
Described two spools two ends separately are equipped with bearing respectively and fix on the end bearing plate, and each establishes a load-bearing suspension rod at least in the middle of them, and this suspension rod upper end is fixed on the beam.
Compare with prior art, the advantage of the collapsible fire screen device of the utility model is: be applicable to that the large span fire prevention cuts off 1.; 2. easy to install.
Description of drawings
Fig. 1 is the cross-sectional schematic of the collapsible fire screen device of the utility model;
Fig. 2 is that the master of described fire screen device driving system 2 looks schematic diagram;
Fig. 3 is the elevational schematic view of described fire screen device driving system 2.
The specific embodiment is described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.
A kind of collapsible fire screen device, as shown in Figure 1, comprise fire prevention cord 1, headstock gear 8, transmission system 2, this transmission system 2 comprises two spools 21,22 that are fixed in fire prevention cord 1 front and back, respectively be connected with can reel thereon steel wire rope 3 of a row who comprises two at least on this two spool 21,22, this two is arranged steel wire rope 3 lower ends and is hung with carriage 4; The lower end of described fire prevention cord 1 is fixed on the described carriage 4, and its upper end is fixing with link plate 5, and this link plate 5 is hung on the installing plate 6 that is fixed on the beam by suspender member 51.Described two spools 21,22 are equipped with bearing 23 respectively and are fixed on the end bearing plate 24 in two ends separately.
Shown in Fig. 2,3, each establishes a load-bearing suspension rod 25 at least on described two spools 21,22, these suspension rod 25 upper ends are fixed on the beam, there is a support plate 26 at central suspension rod place on this two spool 21,22, headstock gear 8 is installed on this support plate 26, spool 21,22 connecting axle 211,221 separately passes described support plate 26, thereby the connection of spool large span and load-bearing problem are resolved.
As shown in Figure 1, described suspender member 51 is a steel wire rope, is provided with screw-button 9 in the middle of it, in the utility model, fire prevention cord 1 is two width of cloth, and corresponding described link plate 5, suspender member 51 and screw-button 9 also all have two groups, and adjustable screw button 9 can make the rate of tension of each steel wire rope basic identical.
As shown in Figure 1, described carriage 4 comprises two parts space, and its cross section is " mountain " font, in the bottom, two parts space of this carriage 4 two groups of pulleys 41 is installed respectively; Each root is all walked around corresponding two pulleys 41 in carriage 4 bottoms in described two row's steel wire ropes 3, up extend to described installing plate 6 and fixing again, described each steel wire rope 3 is positioned at installing plate 6 belows, all is provided with screw-button 32 respectively with the screw-button 9 close positions places of fire prevention cord 1 top, and the effect of these screw-buttons 32 is identical with the effect of described screw-button 9.When rising, occur folding chaotic for fear of fire prevention cord 1, on fire screen 1, vertically evenly be provided with and induce ring 12, described each steel wire rope 3 passes each row respectively and induces ring 12, and each row induces ring 12 numbers at same horizontal level mostly to be the radical of row's steel wire rope 3 most.
