Problems solved by technology

[0003] The national standard for fire shutters stipulates that fire shutters should have the function of closing the hole by falling down by their own weight in case of power failure, that is, if there is no electricity in the event of a fire, the fusible release device on the fire shutters will be burnt by fire, and the pull Open the brake of the fire-proof rolling door machine, and the fire-proof shutter will slide down by its own weight until the opening is closed. When the curtain hits, at the same time, in the case of a power failure, the electric controller of the roller blind fails to effectively control the descent and stop of the roller blind, which reduces the reaction time of the escapees, and easily leads to those who have not evacuated in time to be locked up and isolated in the fire within the area

Abstract

The invention relates to the technical field of fire-fighting equipment, and discloses a fire resisting shutter capable of controlling slip speed and stopping falling at any time. The fire resisting shutter comprises a shutter box, wherein a rotating shaft is movably connected to the interior of the shutter box, the outer side of the rotating shaft is fixedly connected with a winding drum, a shutter is arranged on the outer side of the winding drum, the outer side of the rotating shaft and located on the right side of the winding drum is fixedly connected with a driving gear, the inner right wall of the shutter box is fixedly connected with a control box, and the left side of the control box is movably connected with a linkage shaft. Under the condition of power failure and fire, a brake is pulled apart after a fuse release device is blown, the self weight of the fire resisting shutter is reduced, a fixed rod and a centrifugal block are driven to rotate through the power generated whenthe fire resisting shutter descends, when the centrifugal block rotates, the centrifugal block is influenced by centrifugal force, so that a friction plate on the centrifugal block is in contact withthe inner wall of the control box, when the descending speed of the fire resisting shutter is accelerated, the rotating speed of the linkage shaft is accelerated, the centrifugal force of the centrifugal block is increased, and the contact friction between the friction plate and the inner wall of the control box is increased.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a fire-proof rolling shutter that controls the sliding speed and can stop falling at any time. Background technique [0002] The fire shutter door is a kind of fire prevention and heat insulation facility suitable for large openings of buildings. Fire shutter doors are widely used in the fire partition areas of industrial and civil buildings, which can effectively prevent the spread of fire and ensure the safety of life and property. They are indispensable fire prevention facilities in modern buildings. [0003] The national standard for fire shutters stipulates that fire shutters should have the function of closing the hole by falling down by their own weight in case of power failure, that is, if there is no electricity in the event of a fire, the fusible release device on the fire shutters will be burnt by fire, and the pull Open the brake of the fire-proof rol...
