Abstract
A collapsible fire prevention curtain, relating to the fire fighting equipment, comprises a piece of hangings (1), a headstock gear (2) and a reel (3). The reel (3) can be rotationally secured on an upper structure by a supporting plate (32), and at least a row (at least two) steel wire ropes (4) are winded on the reel (3), which is driven by the headstock gear (2) through an actuating device (21). A base (5) is hung at the lower end of the steel wire ropes (4). The lower end of the hangings (1) is positioned in the base (5), and the upper end of the hangings (1) is overhung on a beam of a top structure by a hanging fitting (6). When the reel (3) is rotated, the base (5) is lowered by the steel wire ropes (4), and the piece of hangings (1) is changed into hanging and unbending state from the state of being collapsed in the base (5). Compared with the prior art, the utility model of collapsible fire prevention curtain, which is appropriate for wide span fire prevention partition, has the advantages of convenient installation and usage and the other properties.
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 cord is wound on the spool, drives spool by headstock gear, thereby makes the cord synchronization lifting that is wound on the spool.Adopt the fire screen of this kind technology to have following deficiency: because cord 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 cord of the diameter of 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, and this fire screen 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, use a kind of collapsible fire screen, comprise cord, headstock gear and spool, this spool is fixed in the superstructure place rotationally by the end bearing plate, described headstock gear is by the actuator drives spool, be wound with row's (at least two) wire rope on the described spool, described wire rope lower end is hung with base; Described cord lower end places in the base, and the cord upper end is hung on the beam of top structure by suspender member; The spool rotation, wire rope puts down base, and cord changes the suspension straight configuration into from being folded in the base.
Compare with prior art, the advantage of the collapsible fire screen of the utility model is: 1. easy to install; 2. can be applicable to that the large span fire prevention cuts off.
Description of drawings
Fig. 1 is the structural representation of the collapsible fire screen of the utility model;
Fig. 2 is that the master of described fire screen spool 3 looks schematic diagram;
Fig. 3 is the elevational schematic view of described fire screen spool 3.
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, as shown in Figure 1, comprise cord 1, headstock gear 2 and spool 3, this spool 3 is fixed in the superstructure place rotationally by end bearing plate 32, described headstock gear 2 drives spool 3 by transmission device 21, be wound with row's (at least two) wire rope 4 on the described spool 3, described wire rope 4 lower ends are hung with base 5; Described cord 1 lower end places in the base 5, and cord 1 upper end is hung on the beam of top structure by suspender member 6; Spool 3 rotations, wire rope 4 puts down base 5, and cord 1 changes the suspension straight configuration into from being folded in the base 5.Described suspender member 6 comprises screw-button 61 and link plate 62.
As shown in Figure 1, described base 5 cross sections are " U " font, and its side height is slightly larger than described cord 1 and is raised the folding thickness in back, can be in the base 5 to guarantee cord 1 fully when the folded state; On the wall at described base 5 two ends, the position in the base 5 dual-sides outsides is separately installed with vertical spacing plate 7, the two ends separately of described base 5 dual-sides are respectively equipped with at least one can be along the vertical pulley 51 that slides, described limiting plate 7 is provided with the chute 71 suitable with pulley 51, makes base 5 that fixing movement locus is arranged when being raised or put down like this and can not vacillate now to the left, now to the right.
As shown in Figure 1, in the utility model, described row's wire rope 4 lower ends are fixed on the centre of base 5, and described cord 1 has two width of cloth and is symmetrically distributed in the both sides, front and back of described row's wire rope 4.
Shown in Fig. 1,3, described headstock gear 2 is installed on the described end bearing plate 32.
As shown in Figure 2, a load-bearing suspension rod 33 is set at least on the described spool 3, these suspension rod 33 upper ends are fixed on the beam, and the load-bearing problem of spool is resolved.
Shown in Fig. 2,3, described spool 3 is provided with steel wire rope groove 34, and its quantity is with the radical of described wire rope 4.
