It is particularly suitable for mechanized loading and unloading of palletized goods, which can improve the efficiency of cargo loading and unloading. For curtain box semi-trailers with a long body and box, due to the large front and rear span, the middle of the roof will sag, so supporting columns must be set in the middle of the box to support the roof. The usual structure is to set one or more movable columns on the left and right sides of the box. In order to prevent the movable columns from interfering with the loading and unloading of pallets on the left and right, the columns can slide back and forth. After the pallets are loaded, the columns are returned to their original positions and fixed.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example: Figure 1-5 As shown, the utility model provides a column device for a curtain semi-trailer, including a mounting plate 1, which is used to be installed and connected with a vehicle body. A rotating shaft 2 is rotatably provided on the outer side of the mounting plate 1, and the rotating shaft 2 assists an adjusting box 21 to perform rotating adjustment, so as to facilitate the folding and opening of the device. An adjusting box 21 is fixedly provided on the outer side of the rotating shaft 2, which is convenient for adjusting the height of a threaded rod 23. A threaded sleeve rod 22 is rotatably inserted in the adjusting box 21, and a threaded rod 23 is inserted in the inner thread of the threaded sleeve rod 22. A top plate 24 is rotatably provided on the top of the threaded rod 23, and a worm gear 3 is fixedly sleeved on the outer side of the threaded sleeve rod 22. The worm gear 3 is located in the adjusting box 21, and a worm 31 is rotatably inserted in the adjusting box 21. The worm 31 and the worm gear 3 are meshed with each other. An auxiliary rod 27 is fixedly provided on the bottom end of the top plate 24, and the auxiliary rod 27 is movably inserted in the adjusting box 21. The stability of the threaded rod 23 can be improved by self-locking the worm gear 3 and the worm 31.

[0021] A connecting plate 4 is fixedly provided on the outside of the regulating box 21 , an arc groove 41 is opened in the mounting plate 1 of the connecting plate 4 , a bolt 42 is movably inserted in the arc groove 41 , the bolt 42 is movably inserted in the connecting plate 4 , and a hexagonal nut 43 is threadedly sleeved on the outside of the bolt 42 .

[0022] By adopting the above technical solution, the device can be folded and stored when not in use, and opened when in use, thereby achieving the purpose of convenient folding and opening.

[0023] Both sides of the mounting plate 1 are fixedly provided with symmetrically distributed mounting blocks 13 .

[0024] By adopting the above technical solution, the mounting block 13 is convenient for mounting the mounting plate 1 .

[0025] A support frame 11 is fixedly disposed on the outer side of the mounting plate 1 .

[0026] By adopting the above technical solution, the support frame 11 can easily support the folded threaded sleeve rod 22.

[0027] Pads 12 distributed in a rectangular array are fixedly provided on one side of the mounting plate 1 away from the regulating box 21 .

[0028] By adopting the above technical solution, the pad 12 provides support between the mounting plate 1 and the vehicle body, making it easier for one end of the bolt 42 to move on the back side of the mounting plate 1 .

[0029] A rotating disk 32 is rotatably disposed on the outer side of the regulating box 21 , and an end of the rotating disk 32 is fixedly connected to the worm 31 .

[0030] By adopting the above technical solution, the rotation of the rotating disk 32 drives the worm 31 to rotate.

[0031] A slide rail 25 is installed on the top of the top plate 24 .

[0032] By adopting the above technical solution, the slide rail 25 assists the curtain to slide.

[0033] A limiting frame 26 is fixedly provided on the top of the regulating box 21 , and an auxiliary rod 27 is movably inserted in the limiting frame 26 .

[0034] By adopting the above technical solution, the limiting frame 26 can assist the auxiliary rod 27 in limiting the position, thereby assisting the threaded rod 23 in height adjustment.

[0035] Working principle: First, the device is installed on the side of the vehicle body through the mounting block 13. When the height of the device needs to be adjusted, the turntable 32 is first rotated, so that the turntable 32 rotates to drive the worm 31 to rotate, and the rotation of the worm 31 drives the mutually meshing worm wheel 3 to rotate, and the rotation of the worm wheel 3 drives the threaded sleeve 22 to rotate, and the rotation of the threaded sleeve 22 drives the threaded rod 23 to move upward or downward with the assistance of the auxiliary rod 27, so that the height of the column as a whole can be adjusted conveniently. At the same time, the self-locking of the worm wheel 3 and the worm 31 can improve the stability of the device. When not in use, the threaded rod 23 can be moved to the bottom end, and then the hexagonal nut 43 is loosened, and then the adjusting box 21 is rotated on the rotating shaft 2, so that the adjusting box 21 rotates ninety degrees, so that the threaded sleeve 22 lies flat, and then the adjusting box 21 can be positioned by tightening the hexagonal nut 43 with the bolt 42 and the connecting plate 4. The device can be folded and stored when not in use, and opened when in use, so as to achieve the purpose of convenient folding and opening.
