[0002] Industrial fans can most efficiently promote large amounts of air movement, generate ultra-large air volumes, form a moving, circulating airflow field in the space, and effectively regulate the air circulation problems in industrial production workshops. Industrial large ceiling fans are a type of large fan that is becoming increasingly popular in factory workshops and warehouses. They mainly consist of fan blades, motors, and hanging brackets. The hanging bracket is a key component to ensure the safe use of industrial large ceiling fans. Industrial ceiling fans are hoisted under the steel beams in the factory building through hanging brackets.

Since the first bevel gear is meshed with the second bevel gear, the screw rod is driven to rotate. At this time, the nut block is forced to move up, thereby driving the double-sided rack fixed to the push rod to move up. Since the double-sided rack is respectively meshed with the two sector gears, the two sector gears are driven to rotate in opposite directions. At this time, the two swing arms are driven to swing toward each other, so that the two clamping frame plates are pressed against the two sides of the ceiling fan body to clamp and fix it.

[0016] 2. In the present invention, by arranging a shock absorbing device, when the ceiling fan body generates vibration during operation, the circular plate is subjected to the vibration. At this time, the second spring and the hydraulic rod are squeezed and contracted to generate elastic force. At the same time, the support frame swings to push the sliding sleeve to move on the support rod. At this time, the first spring is pulled and stretched to generate elastic force. The resonance force can be offset and weakened by utilizing the elastic force of the hydraulic rod, the second spring and the first spring. Moreover, by movably connecting through the universal joint, the vibration in multiple directions can be reduced, thereby ensuring the stability of the connection between the fixed angle plate and the steel top beam, preventing loosening and improving safety.

[0030] The front side wall of the fixed bar housing 11 is fixedly connected with an anti-collision ring 18 , which is located outside the handwheel rod 12 to prevent accidental collision with the handwheel rod 12 .

[0031] The lower side wall of the fixed bar housing 11 is provided with two sliding holes 19 which are connected with the rectangular housing 4 . The two push rods 17 are respectively passed through the two sliding holes 19 to facilitate the displacement of the push rods 17 .

[0032] The bottom of the rectangular shell 4 is fixedly connected with a spring rod 20, and the lower end of the spring rod 20 is fixedly connected with a clamping plate 21. When the lower end of the clamping plate 21 fixed with the spring rod 20 is pressed against the upper end of the ceiling fan body 33, it can prevent it from shaking up and down between the two clamping frame plates 10, and the fixation is more secure.
