Abstract
The utility model relates to a inorganic foldaway fireproof scroll, comprising a scroll motor and a scroll axle, which is characterized in that: the scroll is also provided with a steel rope, a pulley, a steel angle holder, splints, ring-pulls and lifting rods, two pieces of curtain cloth are fixed with two steel angle frames with a plurality of splints; a ring-pull is welded at the interior of the splint; the steel rope is led though the ring-pull and the lifting rod to implement fireproof partition such as U, L, arc and large span, the operation is reliable with low noise and special class fireproof capacity.
Description
Technical field
The utility model relates to a kind of fire protection equipment device that carries out fire separation in irregular fire compartmentation, especially can turn, and arc turns to the fire curtain with super-large span.
Background technology
At present, the curtain body of well-known fire curtain all is rectilinear, twist in during rising on the spool, commander's rolling door motor action when controller receives fire alarm, the curtain body on the drive spool turning handle spool discharges sealing fire compartmentation hole and reaches the fire separation purpose.But, the fire separation place of the fire prevention fire compartmentation that has: U-shaped; L shaped; Arc and super-span all is that the middle not strutting one door frame roller shutter of requirement is finished fire separation.General fire curtain is difficult to satisfy this requirement, causes difficulty for the fire separation in these special places.
Summary of the invention
Can not be in order to solve present fire curtain to the fire separation of the fire compartmentation of U-shaped, L shaped, arc and super-span, the purpose of this utility model is to provide a kind of inorganic collapsible fire curtain, this fire curtain can not only solve the fire separation of the fire compartmentation of U-shaped, L shaped, arc and super-large span, and security of operation is steady, noise is little, and it is superfine that fireproof performance reaches.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of inorganic collapsible fire curtain comprises rolling door motor, spool, it is characterized in that also comprising: wire rope, pulley, slotted-angle shelving, cord, clamping plate, draw ring and lifting arm, and wherein cord has two, is separately fixed on two slotted-angle shelvings; Evenly be fixed with some clamping plate on the cord; The inboard of clamping plate is welded with draw ring; Wire rope is connected with draw ring and lifting arm on the clamping plate of both sides by pulley.
According to the inorganic collapsible fire curtain that the utility model provides, it is characterized in that comprising some door frames inorganic collapsible fire curtain according to claim 1, connect with cord between the wherein adjacent door frame.
Wherein the fire compartmentation hole directly over along the trend of its fire separation, balance crane system two stripe pitch are the slotted-angle shelving of 300mm, as the suspension bracket of hanging cord, the position is provided with a pulley every 700mm therebetween.Turn to according to the fire compartmentation hole, the needs of span, at many spools of the other design and installation of slotted-angle shelving, every spool is established the individual volume door motor, connects a wire rope every 700mm on the spool, and the position is just corresponding to pulley.Wire rope couples together with the same steel pipe lifting arm of slotted-angle shelving trend by pulley again.The steel pipe lifting arm is by the wire rope ground that hangs that plays.
Cord is the inorganic door curtain made of cloth body of making according to the specification at fire compartmentation hole; And every 500mm 3*30mm clamping plate (turning stagger 400mm clamping plate are not set) are set from bottom to top, on the inboard clamping plate of curtain body, weld a nut every 600mm.Two width of cloth curtain bodies are connected on the slotted-angle shelving, and cord is then according to the shape at the fire compartmentation hole whole hole of ground face closure that hangs.Be connected with the long steel wire tow line symmetry of 300mm on the nut of two width of cloth curtain body clamping plate, two width of cloth cords are organically coupled together.Lifting arm is located at the below of steel wire tow line.
Several door-rolling machines of same door frame roller shutter are carried out synchronous operation by synchronized, drive spool running separately, the turning handle of spool is connected wire rope roll on the spool on spool, thereby pulling is connected wire rope other end lifting arm, the motion of lifting arm is risen to drive and is promoted the steel wire tow line that connects two curtain bodies, the rising of steel wire tow line drives folding in an orderly manner rising of cord of connecting cleat. and by a series of power transmission campaigns, the curtain folded body rises to the slotted-angle shelving bottom.Door-rolling machine backwards rotation when controller is received fire alarm, the wire rope that twists on the spool discharges, and the curtain body drops to ground by the gravity tensioning steel wire rope speed of self, and the whole hole of sealing is separated in smooth expansion, reaches the purpose of fire compartmentation fire separation.
Utilize soft inorganic fire cloth as the curtain body, can turn to and turn to along with the fire compartmentation hole; Utilization is independent spool from present curtain body spool one, and its number can need increase because of turning, span strengthen along with the fire compartmentation hole; Utilize to connect wire rope on the spool simultaneously, be arranged at the lifting arm under the curtain body and be located at steel wire tow line between two width of cloth cords, reach decline in order folding in order rising of the active force lower curtain body of door-rolling machine, under the situation that need not add feigned column, realize the enclosing of fire compartmentation hole of U-shaped, L shaped, arc and super-large span, reach the purpose of fire separation.
The beneficial effects of the utility model are: not only can carry out fire separation in general fire compartmentation, and can carry out fire separation at the special fire compartmentation hole of U-shaped, L shaped, arc and super-large span, promote the function of use of fire curtain greatly, prolonged its application life.
