[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1, as Figure 1-3 As shown, a novel fully enclosed lifting column structure for livestock and poultry transport vehicles includes a fixed column 2 with an internal cavity, a movable column 3 connected to the roof 1 of the vehicle body at the upper part of the fixed column 2, and a lifting cylinder 4 connected to the movable column 3 at the lower part of the fixed column 2. The inlet and outlet of the lifting cylinder 4 are connected to buffer regulating valves 5. During operation, the reciprocating motion of the cylinder drives the roof 1 of the vehicle body to rise and fall, which can reduce manufacturing costs and facilitate maintenance.

[0019] In this embodiment, the upper end of the movable column 3 is provided with a connecting plate 6 that is laterally connected to the roof 1 of the carriage. The connecting plate 6 is fixed to the roof 1 of the carriage by bolts. The lower end of the movable column 3 is connected to the upper end of the lifting cylinder 4 by a fixing pin 7. The bottom end of the fixed column 2 is provided with a lower bolt hole. The bottom end of the lifting cylinder 4 is provided with a base hinge center hole. The lower bolt hole and the base hinge center hole are connected by a stainless steel bolt 8. The top end of the fixed column 2 is provided with an upper outlet that facilitates the extension and retraction of the movable column 3. The lower side of the fixed column 2 is provided with a lower opening that facilitates the loading and unloading of the lifting cylinder 4. The lower opening is connected with a sealing plate 9 by bolts to protect the lifting cylinder 4. The outer wall of the fixed column 2 is provided with a support pad 10. The support pad 10 provides auxiliary support after the roof 1 of the carriage is lowered. The middle and lower sides of the outer wall of the fixed column 2 are provided with at least two sets of connecting blocks 11. Multiple connecting blocks 11 facilitate the stacking of livestock and poultry frames.

[0020] The movable column 3 and the lifting cylinder 4 are connected as a whole by the upper fixing pin 7 and then inserted into the fixed column 2 from the upper port. When inserting, the center hole of the base hinge of the lifting cylinder 4 is aligned with the lower bolt hole of the fixed column 2. Then, stainless steel bolts 8 are passed through the aligned concentric holes. The upper connecting plate 6 of the movable column 3 and the cross brace of the car roof 1 are fixed with bolts at the corresponding positions. The buffer adjustment valves 5 at the inlet and outlet of the lifting cylinder 4 are connected with air pipes and then bundled neatly. They come out from the lower port of the fixed column 2 and are connected to the air source control valve. By opening and closing the control valve, the lifting cylinder 4 is reciprocated, which drives the car roof 1 to rise and fall. At the same time, the buffer adjustment valve 5 is manually adjusted to make the two column lifting cylinders 4 reciprocate synchronously. After the adjustment is appropriate, the sealing plate 9 is sealed to the lower opening of the fixed column 2 with bolts.

[0021] Example 2, as Figure 4 As shown in this embodiment, the upper part of the fixed column 2 is provided with a movable column 3 connected to the roof 1 of the vehicle body, the lower part of the fixed column 2 is provided with a rotating screw 12, the movable column 3 is provided with a nut 13 that is connected to the rotating screw 12, the bottom end of the fixed column 2 is provided with a base plate 14, the lower end of the base plate 14 is equipped with a servo motor 15, the output shaft of the servo motor 15 is connected to the rotating screw 12, and the screw is driven to rotate by the servo motor 15. The movable column 3 can move up and down under the action of the matching nut 13, thereby realizing the lifting and lowering of the roof of the livestock transport vehicle.
