[0021] In this embodiment, the first upper hanging bracket 5 and the second upper hanging bracket 8 are respectively provided with a first hanging ear 17, a second hanging ear 18, and a third hanging ear 19 at their rear, middle, and front portions. Three first steel wire ropes 21, three second steel wire ropes 22, and three third steel wire ropes 23 are wound on the wire reel 6. The three first steel wire ropes 21 are connected to the three first hanging ears 17 after passing through guide components. The three second steel wire ropes 22 are connected to the three second hanging ears 18 after passing through guide components. The three third steel wire ropes 23 are connected to the three third hanging ears 19 after passing through guide components. There are a total of nine steel wire ropes, one end of which is connected to the wire reel 6, and the other end is connected to the first hanging ears 17, the second hanging ears 18, and the third hanging ears 19 of the two first upper hanging brackets 5 and the second upper hanging bracket 8.

[0022] In this embodiment, each of the three liftable upper hanging brackets (left, center, and right) has four guide pulleys to guide the wire rope. The multiple vertically fixed steel pipes include a first vertically fixed steel pipe 1, a second vertically fixed steel pipe 2, and a third vertically fixed steel pipe 3 arranged sequentially from front to back. Each vertically fixed steel pipe has a base at its lower part, which connects it to the ground for support. The guiding components include a first guide pulley 13, a second guide pulley 14, a third guide pulley 15, and a fourth guide pulley 16. The first guide pulley 13, the second guide pulley 14, and the third guide pulley 15 are located on the inner side of the drying room roof. The first guide pulley 13 and the second guide pulley 14 are located at the top of the third vertically fixed steel pipe 3 and the second vertically fixed steel pipe 2, respectively. The third guide pulley 15 is located between the first vertically fixed steel pipe 1 and the second vertically fixed steel pipe 2.

The sleeves 20 are fitted onto the vertically fixed steel pipe to restrict the lateral freedom of the upper hanging bracket.

[0026] In this embodiment, the drive assembly includes a motor 11 and a reducer 12. The motor 11 is connected to the reducer 12, and the output end of the reducer 12 is connected to a wire reel 6. The rotation of the motor 11 controls the transmission of the reducer 12, causing the wire reel 6 to move. The wire reel 6 winds up and unwinds the wire rope, causing the upper hanging clamp to move vertically. The reducer 12 is preferably a dual-output shaft reducer, with the wire reel 6 connected to both output shafts. One end of the wire reel 6 is connected to the output end of the reducer 12, and the other end is connected to a bearing 9.
