[0029] By adopting the above technical solution, under the action of the two limiting rings 16, the fixed belt 15 can be limited to prevent the fixed belt 15 from shifting during the process of moving and winding, which affects the use effect of the fixed belt 15. And under the action of the rubber rings, friction between the fixed belt 15 and the limiting rings 16 can be avoided, and thus wear of the fixed belt 15 can be avoided.

[0030] Specifically, an L-shaped rod is connected to the side wall of the fixed-end box 11. A pressing plate is arranged inside the L-shaped rod. A return spring is connected between the pressing plate and the L-shaped rod. A threaded hole is arranged on the L-shaped rod, and a pressing screw is connected inside the threaded hole.

[0031] By adopting the above technical solution, rotate the pressing screw to make it rotate and move along the threaded hole, and then the pressing plate can be driven to move to press and fix the rotating rod 13, and thus the fixed belt 15 can be limited and fixed to prevent the fixed belt 15 from moving during use, and thus the use effect of the fixed belt 15 can be ensured.

[0032] In use of this embodiment, the lifting mechanism 4 is utilized to drive the lifting platform 3 to move, so that the height of the lifting platform 3 is consistent with the height at the goods placement position.

The fixing hook 12 is used to perform a limiting and fixing operation on the fixing frame 14. The movement of the fixing frame 14 drives the movement of the fixing belt 15, so that the fixing belt 15 fits on the outer surface of the goods on the lifting platform 3. Then, the rotating rod 13 is rotated. The rotation of the rotating rod 13 drives the fixing belt 15 to be wound onto the rotating rod 13, ensuring the tension of the fixing belt 15. Furthermore, the fixing effect of the fixing belt 15 on the goods can be ensured, and thus the goods can be prevented from falling and being damaged during the subsequent movement and transportation of the goods. Then, the goods are driven to move and transport by the rotating wheels 5 under the bottom frame 6;

[0033] Embodiment 2

[0034] The difference between this embodiment and Embodiment 1 is that the moving and lapping component 2 includes a lapping plate 21, a placement groove 22, a moving groove 23, a rotating screw 24 and a threaded sleeve 25. A placement groove 22 is arranged above the lifting platform 3. A lapping plate 21 is arranged inside the placement groove 22. A moving groove 23 is arranged below the placement groove 22. A rotating screw 24 is connected inside the moving groove 23. A threaded sleeve 25 is connected between the outer side wall of the rotating screw 24 and the lapping plate 21.

[0035] Specifically, a guiding slider is connected to the side of the threaded sleeve 25 away from the lapping plate 21. A guiding chute is arranged on the inner side wall of the moving groove 23 at a position corresponding to the guiding slider.

[0036] By adopting the above technical solution, the movement of the guiding slider in the guiding chute can provide a guiding effect for the movement of the threaded sleeve 25, avoiding the threaded sleeve 25 from rotating during the rotation of the rotating screw 24, ensuring that the threaded sleeve 25 can move along with the rotation of the rotating screw 24. Furthermore, the movement of the threaded sleeve 25 can be utilized to drive the lapping plate 21 to move, lap the goods, and facilitate the movement operation of the goods.

[0037] In use of this embodiment, when the lifting platform 3 is lifted to a height consistent with the goods placement position and there is a spacing gap between the goods and the lifting platform 3, the rotating screw 24 is rotated. The rotation of the rotating screw 24 drives the threaded sleeve 25 to move inside the moving groove 23. The movement of the threaded sleeve 25 drives the lapping plate 21 to move inside the placement groove 22. When the lapping plate 21 laps to the goods placement position, the rotation of the rotating screw 24 is stopped. Then, the goods are moved along the lapping plate 21 onto the lifting platform 3, facilitating the goods loading operation and reducing the labor burden of the staff.

[0038] The structure and principle of the lifting mechanism 4 composed of a hydraulic rod and a telescopic rod in the present utility model have been disclosed in a high-stability freight lifting platform disclosed in Chinese Patent Application No. 202122363123.X. Its working principle is as follows: A hydraulic rod is connected above the bottom frame 6, and a telescopic rod is connected between the lifting table 3 and the bottom frame 6. The hydraulic rod is used to drive the lifting table 3 to move, and the movement of the lifting table 3 drives the telescopic rod to expand and contract.

[0039] The working principle and usage process of the present utility model: The present utility model uses the lifting mechanism 4 to drive the lifting table 3 to move, so that the height of the lifting table 3 is consistent with the height at the cargo placement position. When the lifting table 3 is lifted to a height consistent with the cargo placement position and there is a spacing gap between the cargo and the lifting table 3, rotate the rotating screw rod 24. The rotation of the rotating screw rod 24 drives the threaded sleeve 25 to move inside the moving groove 23. The movement of the threaded sleeve 25 drives the lapping plate 21 to move inside the placement groove 22. When the lapping plate 21 reaches the cargo placement position, stop rotating the rotating screw rod 24, and then move the cargo along the lapping plate 21 onto the lifting table 3, which facilitates the loading operation of the cargo and reduces the labor burden of the staff. Then, pull the fixed frame 14 to make the fixed frame 14 snap onto the fixed hook 12, and use the fixed hook 12 to perform a limiting and fixing operation on the fixed frame 14. The movement of the fixed frame 14 drives the fixed belt 15 to move, so that the fixed belt 15 fits on the outer surface of the cargo on the lifting table 3. Then, rotate the rotating rod 13. The rotation of the rotating rod 13 drives the fixed belt 15 to be wound onto the rotating rod 13, ensuring the tension of the fixed belt 15, and thus ensuring the fixing effect of the fixed belt 15 on the cargo. Furthermore, it can prevent the cargo from falling and being damaged during the subsequent movement and transportation of the cargo. Then, drive the cargo to move and transport through the rollers 5 below the bottom frame 6.
