Description

Technical Field

[0001] The utility model relates to a winding device, in particular to a winding device for a fire shutter. Background Art

[0002] Fire shutter doors are widely used in fire separation areas of industrial and civil buildings. They can effectively prevent the spread of fire and protect life and property safety. They are indispensable fire protection facilities in modern buildings. It is a movable fire separation, generally made of metal plates such as steel plates, and is composed by means of snap rings or hinges. Usually, it is rolled up in the rotating shaft box at the upper opening of the door and window. When a fire breaks out, it is lowered and unfolded to prevent the fire from spreading from the door and window openings. In case of a fire caused by modern equipment and human factors, the fire shutter door plays a role in isolating the speed of fire spread.

[0003] When the existing fire shutter door is in use, although it is possible to facilitate the downward operation of the shutter door and improve the fire resistance of the shutter door by setting an outer nano-aluminum hydroxide flame retardant layer, an inner nano-aluminum hydroxide flame retardant layer, a non-Newtonian fluid, a telescopic rod, a slide rail and a slider structure, the winding operation of the shutter door is relatively cumbersome. Summary of the Utility Model

[0004] The main purpose of the present disclosure is to provide a winding device for a fire shutter to effectively solve the problems raised by the inventor in the above background art.

[0005] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] A winding device for a fire shutter includes a shutter main body and a shutter protective cover. A horizontally arranged reciprocating rotating shaft is rotatably installed inside the shutter protective cover, and a winding roller is fixedly installed on the reciprocating rotating shaft. A fireproof cloth is wound around the winding roller, and the other side of the fireproof cloth is in a hanging state and is fixedly connected to the shutter main body. An outlet is opened at the bottom of the shutter protective cover. The lower end of the shutter main body passes through the outlet and is fixedly connected to a counterweight bar, and the length value of the counterweight bar is larger than the length value of the outlet.

[0007] Preferably, two symmetrically arranged positioning stop bars are fixedly connected to the outer edge of the outlet, and the bottom ends of the positioning stop bars are arc-shaped.

[0008] Preferably, a servo motor is fixedly installed on the side of the shutter protective cover. The output end of the servo motor is fixedly connected to a driving shaft, and the right end of the driving shaft extends into the shutter protective cover and is fixedly connected to a first gear. A second gear is fixedly installed on the reciprocating rotating shaft, and the second gear meshes with the first gear.

[0009] Preferably, a plurality of uniformly distributed soft cleaning brushes are fixedly connected to the inner wall of one side of the outlet, and the other ends of the soft cleaning brushes are in contact with the front surface of the shutter main body.

[0010] Preferably, a controller is fixedly installed on the rolling shutter protective cover, and a smoke sensor and an alarm are installed on the controller. Both the smoke sensor and the alarm are electrically connected to the controller.

[0011] Preferably, the surface of the rolling shutter body is coated with a fireproof coating.

[0012] In view of this, compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] (1) In this application, when the rolling shutter body is retracted, the servo motor works to drive the driving shaft to drive the first gear to rotate. Under the meshing transmission with the second gear, the reciprocating rotating shaft drives the winding roller to rotate, so as to wind up the fireproof cloth and the rolling shutter body, so that the rolling shutter body moves upward and is stored in the rolling shutter protective cover. When in use, the winding roller releases the rolling shutter body, and under the gravity traction of the counterweight strip, the rolling shutter body can move down smoothly.

[0014] (2) In this application, the fireproof cloth and the fireproof coating on the rolling shutter body can achieve a good fireproof effect. The smoke sensor can detect smoke and send an output signal to the controller to control the alarm to emit a warning sound, thereby reminding the user to take safety measures and avoid unnecessary losses and injuries.
