Description

Technical Field

[0001] The invention specifically relates to a rolling door machine for fireproof rolling shutters which is easy to install and belongs to the technical field of rolling shutter doors. Background Art

[0002] Fireproof rolling shutters are mainly used for walls that need fire separation, especially fire separation on fire walls and fire partitions when large openings are required for production and use but fire doors cannot be installed. Fireproof rolling shutters are essential facilities for fire protection in modern buildings and are widely used in high-end hotels, restaurants, libraries, theaters, large shopping malls, stations, underground projects, factory buildings, warehouses, garages and other buildings. Fireproof rolling shutters are usually rolled up in the shaft box at the top of doors and windows. When a fire occurs, they are lowered and unfolded to prevent the fire from spreading from the door and window openings. When the fireproof rolling shutters are rolled up or lowered, a rolling door machine is required to facilitate the reeling of the fireproof rolling shutters.

[0003] As disclosed in publication number (CN216043455U), a fireproof roller shutter machine that is easy to install includes a mounting plate. Specifically, the mounting plate of the utility model can be installed at any position by means of bolts; and a connecting plate is provided on the mounting plate. During the process of the connecting plate being embedded in the mounting groove, the connecting plate uses a downward force, and under the action of a spring, a clamping block on the mounting plate is embedded in a clamping groove provided on the connecting plate, so that the clamping block and the clamping groove are nested, and an electromagnetic plate in the clamping groove is attracted to the clamping block, so that the connecting plate is fixed after being embedded in the mounting groove. Therefore, when installing the roller shutter machine, the connecting plate is welded to the bottom of the roller shutter machine, and the roller shutter machine is installed on the mounting plate by means of the connecting plate, so that the roller shutter machine is fixed on the wall. Thus, the existing method of installing the roller shutter machine is changed to prevent the problem of injury caused by falling tools during the process of installing the roller shutter machine at high altitude due to the need to support the roller shutter machine all the time due to the weight of the roller shutter machine, thereby improving the efficiency of installation.

[0004] Although the above technical solution improves the installation efficiency, the driving mode of the roller remains unchanged during use, and the manually driven fire shutter door rolling process is not convenient enough. In the event of a power outage, the electrically driven fire shutter door cannot be folded up and lowered. The fire shutter door can only be folded up and lowered by driving the roller to rotate in a separate manner. The use is not flexible enough and there are certain disadvantages in the use process.

The use is more flexible, so as to switch the driving mode of the winding of the fire shutter door body 3 to meet different usage requirements, so that the fire shutter door body 3 can operate in different situations. When the fire shutter door body 3 is folded or lowered, the fire shutter door body 3 moves in contact with the correction roller 902, so that the correction roller 902 limits the fire shutter door body 3. At the same time, under the action of the limiting frame 2, the fire shutter door body 3 is effectively avoided from being offset when it is folded or lowered.
