[0015] Compared with the prior art, the beneficial effects of this utility model are: the large item anti-fall protection device for logistics transportation not only makes it easy to adjust the side plate and the height of the pressure plate, but also makes it easy to cushion the goods;
[0016] (1) By setting a side plate, protective shell, worm gear, rotating shaft, worm, and second servo motor, the second servo motor is started when the side plate needs to be opened to adjust the angle of the side plate. The second servo motor drives the worm gear to rotate through the worm. The rotation of the worm gear can cause the rotating shaft to drive the bottom end of the side plate to rotate inside the reserved groove, so that the side plate can be opened to facilitate the staff to put the goods from one side of the transport vehicle platform to the top of the transport vehicle platform.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-4 The present invention provides an embodiment of a large item anti-fall protection device for logistics transportation, including a transport vehicle platform 1, a side panel 2 of the vehicle box fixedly connected to the top of the transport vehicle platform 1, a housing 4 fixedly connected to the left side of the top of the transport vehicle platform 1, a side panel 14 provided on the right side of the top of the transport vehicle platform 1, and a drive structure for facilitating the opening of the side panel 14 provided at the bottom and front of the side panel 14.
[0026] The drive structure includes a worm gear 16, a rotating shaft 17, and a worm 18. A reserved slot 21 is provided on the right side inside the transport vehicle plate 1. The rotating shaft 17 is movably connected to the outside of the reserved slot 21. The worm gear 16 is fixedly connected to the front end of the rotating shaft 17. A protective shell 15 is provided on the right side of the front end of the transport vehicle plate 1. A second servo motor 22 is installed at the bottom left side of the protective shell 15. The output end of the second servo motor 22 is fixedly connected to the worm 18.
[0027] The worm 18 is located at the bottom end of the worm wheel 16, and the worm wheel 16 and the worm 18 cooperate with each other. The side plate 14 is located on the right side inside the side plate 2 of the carriage, and the rotating shaft 17 is fixedly connected to the bottom end inside the side plate 14.
[0028] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when the angle of the side plate 14 needs to be adjusted to open the side plate 14, the second servo motor 22 is activated. The second servo motor 22 drives the worm wheel 16 to rotate through the worm gear 18. The rotation of the worm wheel 16 can cause the rotating shaft 17 to drive the bottom end of the side plate 14 to rotate inside the reserved groove 21, thereby opening the side plate 14 so that the staff can place the goods from one side of the transport vehicle plate 1 to the top of the transport vehicle plate 1. After placing the goods, the side plate 14 is rotated back to its original position to limit the side of the goods and prevent the goods from falling.
[0029] A first servo motor 3 is installed at the bottom of the housing 4. A threaded rod 5 is fixedly connected to the output end of the first servo motor 3. A lifting sleeve 7 is provided on the outside of the threaded rod 5. A top plate 8 is fixedly connected to the top of the lifting sleeve 7. A connecting block 13 is fixedly connected to the right side of the bottom end of the top plate 8. A threaded groove 25 is opened inside the lifting sleeve 7. An external thread is machined on the outside of the threaded rod 5. An internal thread that matches the external thread is machined inside the threaded groove 25. The threaded rod 5 and the threaded groove 25 cooperate with each other. A limit block 24 is fixedly connected to the bottom left side of the lifting sleeve 7. A slider 23 is fixedly connected to the left side of the limit block 24. A slider 23 is opened on the left side inside the housing 4. The slider 23 slides up and down inside the limit groove 6.
[0030] Specifically, such as Figure 1 and Figure 4 As shown, the first servo motor 3 is started, and the first servo motor 3 drives the threaded rod 5 to rotate. Since the threaded rod 5 and the threaded groove 25 inside the lifting sleeve 7 cooperate with each other, and the top plate 8 is fixedly connected to the top of the lifting sleeve 7, the rotation of the threaded rod 5 can cause the lifting sleeve 7 to drive the top plate 8 to descend. This allows the pressure plate 9 at the bottom of the top plate 8 to limit the top of the goods, preventing the goods from accidentally falling during transportation and causing safety accidents. Therefore, limiting the goods can improve safety.
[0031] A second pad 20 is fixedly connected to the inner wall of the side panel 2 of the carriage, a first pad 19 is fixedly connected to the inner wall of the side panel 14, a pressure plate 9 is provided at the bottom of the top plate 8, a buffer pad 10 is provided at the bottom of the pressure plate 9, a spring 11 is fixedly connected between the pressure plate 9 and the top plate 8, a damper 12 is provided inside the spring 11, and the damper 12 is provided between the pressure plate 9 and the top plate 8.
[0032] Specifically, such as Figure 1 As shown, after the top plate 8 descends to the appropriate position, the pressure plate 9 can press against the top of the goods. When encountering bumps, the spring 11 will cushion the goods with its own elasticity, protecting the goods from damage during transportation. The damper 12 inside the spring 11 can limit the spring 11, improve the stability of the spring 11, and prevent the spring 11 from shaking too much and affecting the limit.
[0033] Working principle: When in use, the second servo motor 22 is activated. The second servo motor 22 drives the worm wheel 16 to rotate via the worm gear 18. The rotation of the worm wheel 16 causes the rotating shaft 17 to drive the bottom end of the side plate 14 to rotate inside the reserved groove 21, thereby opening the side plate 14 to facilitate the worker to place the goods from one side of the transport vehicle platform 1 to the top of the transport vehicle platform 1. After placement, the side plate 14 is rotated back to its original position to limit the side plate 14 to one side of the goods. After closing the side plate 14, the first servo motor 3 is activated. The first servo motor 3 drives the threaded rod 5 to rotate. The rotation of the threaded rod 5 causes the lifting sleeve 7 to... The moving top plate 8 descends, thereby limiting the top of the goods by the pressure plate 9 at the bottom of the top plate 8, preventing the goods from falling accidentally during transportation and causing safety accidents. Therefore, limiting the goods can improve safety. When the lifting sleeve 7 is raised and lowered, the slider 23 will slide up and down inside the limiting groove 6, thereby improving the stability of the lifting. When encountering bumps, the spring 11 will cushion the goods with its own elasticity, protecting the goods from damage during transportation. The damper 12 inside the spring 11 can limit the spring 11, improve the stability of the spring 11, and prevent the spring 11 from shaking too much and affecting the limiting.
