Technical Field
[0001] The utility model relates to the technical field of industrial large fans, and particularly relates to an anti-falling fixing device for industrial large fans. Background Art
[0002] Industrial large fans are fans specially designed for industrial environments, featuring large air volume, high power, and strong durability. Thus, they are widely used in places such as factories and warehouses that require large-area ventilation and cooling. Industrial large fans are usually directly fixed to the wall and generally have limited rotation angles.
[0003] According to the "anti-falling fixing device for industrial large fans" with the Chinese patent publication number CN220185458U, it mainly describes that after the fan base is installed through the set support unit, the fan rod is located above the support frame. The support frame is driven upward by an electric elevator, so that the support frame supports the fan rod. When adjusting the position of the support frame, by pulling out the positioning pin and rotating the turntable, the gear is driven to rotate. The gear is meshed with the toothed plate, so that the telescopic plate moves back and forth, facilitating the adjustment of the positions of the telescopic plate and the support frame according to the length of the fan rod, improving the stability of the support, and preventing the fan from falling during operation. During the process of adjusting the rotation direction of the fan, the fan blade structure and the fan main body are both driven to rotate by a driving motor, which is likely to cause instability during support and lead to the fall of the fan.
[0004] Therefore, an anti-falling fixing device for industrial large fans is proposed to solve the problem that during the process of adjusting the rotation direction of the fan, the fan blade structure and the fan main body are both driven to rotate by a driving motor, which is likely to cause instability during support and lead to the fall of the fan.

The output end of the third motor is fixedly connected with a fan body 8. The third motor causes the fan body 8 to rotate, which can generate an air - guiding structure. A support bar 10 is fixedly connected to the side of the second rotating frame 7 away from the fan body 8. One side of the support bar 10 is rotatably connected with a pulley 11 through a rotating shaft. By the cooperation of the support bar 10 and the pulley 11, it can provide support for the second rotating frame 7 in the arc - shaped groove, thus solving the problem of preventing the industrial fan from falling.
[0018] Among them, the pressing plate 16 is fixedly connected to the output end of the electric push rod 13. The electric push rod 13 is fixedly connected to the side of the connecting block 12 away from the second rotating frame 7. The connecting block 12 is fixedly connected between the two support bars 10. By providing the pressing plate 16, support can be provided on one side of the support bars 10 and the pulleys 11, improving the stability when the second rotating frame 7 rotates.
