Abstract
The utility model discloses a wide-width fireproof rolling door with an invisible guide rail, belonging to the technical field of fire-fighting instruments. The rolling door comprises a rolling motor, a roller shutter and the guide rail. The rolling door is characterized in that the guide rail is a retractable invisible guide rail, and the retractable invisible guide rail consists of a guide rail electrical machine and a guide rail hinged support arranged on a door girder, a retractable invisible guide rail articulated with the guide rail hinged support, a retractable mechanism of the guide rail arranged between the guide rail electrical machine and the guide rail, a guide rail positioning mechanism arranged at the end of the guide rail and a guide rail stop block installed on the ground corresponding to the guide rail. The wide-width fireproof rolling door has the advantage of being capable of obtaining the fireproof rolling doors with any width through multi-gear combination. The combination angles of each gear combination can be discretionary, so that the door can be completely used for various door frames such as arc door frames, corner door frames and the like.
Description
Technical field
The utility model relates to the fire resistance rolling shutter door in the extinguisher field.
Background technology
Existing fire resistance rolling shutter door is made of motor, roller shutter and guide rail.Guide rail is fixedly mounted on the building doorframe, is moved in guide rail by the driven by motor roller shutter.Owing to the reason of roller shutter deadweight can not do very wide.The Breadth Maximum of seeing the rolling door that has at present is no more than 16M.Therefore can not satisfy some installing and using as these roomy shop fronts of hangar, corner occasion.
The utility model content
The purpose of this utility model provides a kind of wide cut fire resistance rolling shutter door with stealthy guide rail.The wide cut fire resistance rolling shutter door of the stealthy guide rail of this band can satisfy installing and using of various roomy, the special-shaped shop fronts, does not under normal circumstances account for the width of the shop front, thereby the normal use of the shop front is had no effect.
The formation of this wide cut fire resistance rolling shutter door comprises roller shutter motor, roller shutter, guide rail, it is characterized in that described guide rail is the stealthy guide rail of extendible, the stealthy guide rail of this extendible by be installed in guide rail motor and guide rail free bearing on the beam, be hinged on extendible guide rail on the guide rail free bearing, be arranged on the guide rail between guide rail motor and the guide rail retractable mechanism, be arranged on the guide rail detent mechanism of rail end and constituted corresponding to the surface-based guide rail limited block of guide rail.
Operating principle of the present utility model is as follows:
With the same roller shutter motor and the roller shutter installed on the building door beam of existing rolling door, guide rail motor and guide rail free bearing also are installed in Men Liangshang, and the guide rail limited block then is installed in ground corresponding to guide rail.Can obtain the fire resistance rolling shutter door of any width by many grades of combinations.Under normal circumstances, roller shutter and guide rail all are stowed in building door beam position.When breaking out of fire, the guide rail motor discharges guide rail, and guide rail is transferred under the effect of deadweight to the guide rail detent mechanism of its end and entered in the guide rail limited block on ground, and guide rail is located.The roller shutter electric motor starting is closed roller shutter then.Earlier roller shutter being risen routinely behind the fire resets, and removes the guide rail detent mechanism again and discharges guide rail, starts the guide rail motor, and it is stealthy on the building door beam that lift rail to horizontal level makes it.
By existing fire resistance rolling shutter door control technology, can be implemented in fire signal when input, confirm that roller shutter restarts the guide rail motor after upper and transfer guide rail and cut off the roller shutter power supply simultaneously and be failure to actuate to guarantee roller shutter.A guide rail is set in the ground guide limited block goes into a travel switch, after guide rail was gone into the position, guide rail was gone into a travel switch and is provided signal, started the roller shutter motor and cut off the guide rail motor power to guarantee that guide rail must not misoperation.
Compared with the aforementioned existing similar products, the utility model has the advantages that the fire resistance rolling shutter door that can obtain any width by many grades of combinations.Between every grade of roller shutter can be arbitrarily in conjunction with angle, thereby can satisfy various special-shaped doorframes such as arc doorframe, corner doorframe fully and use.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.

The specific embodiment
Referring to Fig. 1～3, the stealthy guide rail of the extendible of this wide cut fire resistance rolling shutter door by be installed in guide rail motor 5 and guide rail free bearing 6 on the beam 4, be hinged on extendible guide rail 3 on the guide rail free bearing 6, be arranged on the guide rail between guide rail motor 5 and the guide rail 3 retractable mechanism, be arranged on the guide rail detent mechanism 7 of guide rail 3 ends and constituted corresponding to the surface-based guide rail limited block 8 of the work station of guide rail.Roller shutter motor 1, roller shutter 2 and fixed guide 9 are continued to use existing structure.The retractable mode of guide rail can be various, as gear drive, wire rope traction etc.In the present embodiment the retractable mechanism of guide rail by the pulley support frame 10 that is arranged on guide rail top, be installed in that pulley 11 and end that is overlapped on the pulley 11 on the pulley support frame 10 is cemented in the guide rail motor shaft, other end clasp joint is constituted in the pull rope 12 of extendible guide rail 3.When needs are closed roller shutter, the guide rail motor discharges pull rope 12, effect lower guideway 3 in deadweight rotates around guide rail free bearing 6, and the guide rail detent mechanism 7 until guide rail 3 ends enters in the guide rail limited block 8 on ground, has promptly constituted traditional rolling door guide rail for transferring roller shutter.The stealthy guide rail of a plurality of extendibles so is set, can be combined into the fire resistance rolling shutter door of any width.Use for satisfying various special-shaped doorframes such as arc doorframe, corner doorframe, the extendible guide rail can be designed to multiaspect, and referring to Fig. 7,20 is guide rail body among the figure, and the 21st, erection column.
Still can extendible guide rail 3 be provided with a tripping mechanism 13 with pull rope 12 snappings.This tripping mechanism 13 can be used existing " labeled door release " and serve as.In guide rail 3 tripping mechanism 13 actions when guide rail free bearing 6 is pivotally lowered into a certain position, make guide rail 3 break away from pull rope 12 and under the effect of deadweight, enter in the guide rail limited block 8 on ground.A rope drawing machine structure 19 is set in this manner pull rope 12, after discharging guide rail, sagging pull rope is packed up.
What Fig. 4 provided is the structural representation of guide rail detent mechanism.Its lower end 15 is a lower end, telescopic inclined-plane that is connected in spring 14.The posterior end 15 that puts in place is stretched out to stumble and is connected in the ground limited block 8.What Fig. 5,6 provided is the structural representation of ground limited block 8, is respectively equipped with two limiting block rank 17 and 18.16 is limit switches among the figure, and limit switch 16 touched with the limiting block rank 17 of ground limited block when guide rail 3 put in place, disconnected the guide rail motor power, connected the roller shutter motor power simultaneously.
