Two air bags 21 are fixed on the relatively inner sides of the limit frame 20 respectively. The air bags 21 are inflated to clamp the fan equipment module.

[0026] The airbag 21 is connected to an air pump 22 through an air filling pipe 23 and an electromagnetic valve 24 , and the air pump 22 inflates the airbag 21 to expand it.

[0027] It also includes an installation base plate 6 that is placed on a transport ship or a construction platform when in use. A lifting frame 7 is fixed to the front side of the installation base plate 6. A lifting plate 8 is installed on the top of a plurality of lifting frames 7 that are spaced apart. A movable bracket 9 is fixedly connected to the lifting plate 8. The movable bracket 9 is rotatably hinged to a lifting rod 11 through a connecting shaft 10. A top plate 12 is fixed to the top of the lifting rod 11. A fixed bracket 13 is fixed to the top of the top plate 12. A lifting arm 14 is fixedly connected to the inner side of the fixed bracket 13. The housing of the lifting motor 15 is fixed to the inner side of the lifting arm 14.

[0028] It also includes a reinforcement frame 1 fixed on the mounting base plate 6, a plurality of reinforcement frames 1 are fixed with reinforcement plates 2 on the top of which are spaced apart, a mounting bracket 3 is fixedly connected to the top of the reinforcement plate 2, the inner sides of the two mounting brackets 3 are fixedly connected by a reinforcement shaft 4, a reinforcement steel cable 5 is rotatably hinged on the reinforcement shaft 4 through a collar, and the reinforcement steel cable 5 is fixedly connected to the top of the lifting rod 11 under the top plate 12; the length of the reinforcement steel cable 5 is controlled to determine the inclination angle of the lifting rod 11 relative to the movable bracket 9.
