[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] like Figures 1-8 As shown, the present invention proposes a positioning plate device for a platform freight track, comprising a support plate 1 and a freight base plate 13. A platform freight track 2 is fixedly connected to the upper part of the support plate 1. A limit plate 3 and a crossbar 7 are fixedly connected to the inner side of the platform freight track 2. Multiple hollow tubes 17 are fixedly connected to the side of the freight base plate 13 closest to the support plate 1. A positioning plate assembly is jointly provided on the platform freight track 2, the limit plate 3, and the crossbar 7. The positioning plate assembly includes a force-bearing column 4 and a spring 5 movably connected to the platform freight track 2, and multiple first electric telescopic rods 9 movably connected to the crossbar 7. When the force-bearing column 4 is compressed by external force, it will compress the spring 5. When the spring 5 is compressed, the corresponding first electric telescopic rods 9 will... The retractable rod 9 extends and retracts to the end away from the support plate 1 and contacts the inside of the hollow tube 17. The platform freight track 2 and the freight base plate 13 are jointly provided with the platform freight track 2. The platform positioning extension assembly includes a wheel 11 and a conveyor belt 12 movably connected on the platform freight track 2, and a platform 21, a fixed shaft 23 and a stabilizing rod 25 movably connected on the freight base plate 13. The rotation of the wheel 11 will drive the freight base plate 13 to move back and forth in the horizontal direction along the conveyor belt 12. When the platform 21 moves to the side closer to the wheel 11, the stabilizing rod 25 will rotate along the fixed shaft 23 due to gravity. The platform freight track 2 is provided with a first sliding hole 27 and a second sliding hole 28 on the side closer to the freight base plate 13.

[0033] The outer side of the platform freight track 2 is slidably connected with the plurality of force columns 4, and the inner side of the platform freight track 2 is provided with a first cavity 18. The plurality of force columns 4 are linearly and uniformly arranged along the platform freight track 2, and the force column 4 is slidably connected with the limiting plate 3. The force column 4 can transmit the pressure on the outer side to the spring 5, so that the spring 5 can further transmit the force.

[0034] The end of the force column 4 close to the limiting plate 3 is fixedly connected with the spring 5. The end of the spring 5 away from the force column 4 is fixedly connected with the pressure sensing element 6. When the pressure sensing element 6 is subjected to the force of the spring 5, it will transmit a signal to the transmission pipe 8. The end of the pressure sensing element 6 away from the spring 5 is fixedly connected with the transmission pipe 8. The transmission pipe 8 penetrates the outer side of the cross rod 7. The end of the transmission pipe 8 away from the pressure sensing element 6 is fixedly connected with the first electric telescopic rod 9. When the transmission pipe 8 receives the signal transmitted by the cross rod 7, the first electric telescopic rod 9 will be started.

[0035] The plurality of first electric telescopic rods 9 are linearly and uniformly arranged along the cross rod 7. The number of the first electric telescopic rods 9 is the same as that of the force columns 4. The number of the first electric telescopic rods 9 corresponds to that of the force columns 4.

[0036] In this embodiment, when the force column 4 is subjected to external pressure, it will extrude the spring 5. When the spring 5 is extruded, the corresponding first electric telescopic rod 9 will be telescopic away from the supporting plate 1 and contact the inner side of the hollow pipe 17, so as to position the freight bottom plate 13 in position. The use of photoelectric sensing equipment is avoided, so as to avoid the influence of environmental light, dust and weather on the photoelectric sensing equipment. The supporting plate 1 mainly plays a supporting role. When the force column 4 is subjected to external extrusion, it will slide to the side close to the limiting plate 3. The number of the force columns 4 is multiple. When the external extrusion extrudes a group of force columns 4, the group of force columns 4 will slide to the side close to the limiting plate 3. At the same time, the force column 4 will extrude the spring 5. When the spring 5 is extruded by the force column 4, it will be deformed, so as to extrude the pressure sensing element 6. When the pressure sensing element 6 senses the extrusion, it will transmit the signal to the first electric telescopic rod 9 through the transmission pipe 8. The first electric telescopic rod 9 will be started when it receives the signal of the pressure sensing element 6. The first electric telescopic rod 9 will be telescopic upward. At the same time, the upper end of the first electric telescopic rod 9 contacts the inner side of the hollow pipe 17, so as to position the batten 21.

[0037] Embodiment two

[0038] As Figures 1-8As shown, based on Embodiment 1, servo motors 10 are symmetrically and fixedly connected to the outer side of the platform freight track 2. The output shaft end of the servo motor 10 is fixedly connected to the wheel 11. The two sets of wheel 11 are connected to the transmission belt 12 for transmission. The start of the servo motor 10 can drive the wheel 11 to rotate, and the rotation of the wheel 11 can drive the transmission belt 12 to drive.

[0039] The outer side of the conveyor belt 12 is fixedly connected to the cargo base plate 13. An L-shaped block 14 is symmetrically fixedly connected to the side of the cargo base plate 13 near the support plate 1. The L-shaped block 14 can keep the cargo base plate 13 stable on the platform cargo track 2. A sliding block 15 is symmetrically fixedly connected to the end of the L-shaped block 14 away from the cargo base plate 13. The sliding block 15 can slide inside the limiting plate 3.

[0040] The outer side of the limiting plate 3 is symmetrically provided with T-shaped grooves 16. The outer side of the T-shaped groove 16 is slidably connected to the L-shaped block 14, and the outer side of the T-shaped groove 16 is slidably connected to the sliding block 15. The L-shaped block 14 and the sliding block 15 can slide simultaneously on the inner side of the T-shaped groove 16, thereby maintaining the stability of the freight base plate 13 on the platform freight track 2.

[0041] The inner side of the cargo floor 13 is provided with a sliding groove 19. A telescopic cylinder 20 is fixedly connected to the inner side of the sliding groove 19. The end of the telescopic cylinder 20 away from the sliding groove 19 is fixedly connected to the deck 21. The deck 21 and the sliding groove 19 are slidably connected. The activation of the telescopic cylinder 20 can push the deck 21 to slide inside the sliding groove 19. The sliding groove 19 can push the deck 21 outward in the horizontal direction.

[0042] A second cavity 22 is symmetrically provided on the side of the step plate 21 near the support plate 1. The inner side of the second cavity 22 is fixedly connected to the fixed shaft 23. A U-shaped block 24 is movably connected to the outer side of the fixed shaft 23. The end of the U-shaped block 24 away from the fixed shaft 23 is fixedly connected to the stabilizer 25. A protective block 26 is fixedly connected to the end of the stabilizer 25 away from the U-shaped block 24. The U-shaped block 24 and the stabilizer 25 will move downward due to gravity. The U-shaped block 24 will rotate outside the fixed shaft 23. The function of the protective block 26 is to protect the stabilizer 25.

[0043] The first sliding hole 27 is slidably connected to the hollow tube 17. There are two sets of second sliding holes 28. The second sliding holes 28 are slidably connected to the L-shaped block 14. The hollow tube 17 will slide inside the first sliding hole 27, and the L-shaped block 14 will slide inside the second sliding hole 28.

[0044] In this embodiment, further, by setting a platform positioning extension component, the rotation of the wheel 11 will drive the cargo floor 13 to move back and forth horizontally along the conveyor belt 12. When the platform 21 moves towards the side closer to the wheel 11, the stabilizing rod 25 will rotate along the fixed axis 23 due to gravity, which has the advantage of more stable and direct cargo docking. Specifically, the movement of the cargo floor 13 and the rise of the first electric telescopic rod 9 are coordinated. The start of the servo motor 10 will drive the wheel 11 to rotate. The rotation of the two sets of wheel 11 can drive the conveyor belt 12 to rotate. 2. Transmission: The transmission belt 12 drives the cargo floor 13 to move horizontally. Multiple hollow tubes 17 are fixedly connected to the lower part of the cargo floor 13. Through adjustment, when the first electric telescopic rod 9 rises, it contacts the inner side of the hollow tube 17. At this time, the transmission belt 12 stops, thus achieving the purpose of positioning the cargo floor 13. The T-slots 16 symmetrically opened on the outer side of the limiting plate 3 match the L-shaped block 14 and the sliding block 15. The L-shaped block 14 and the sliding block 15 can slide inside the T-slots 16. The function of the movable block 15 is to ensure that the cargo base plate 13 always slides outside the limiting plate 3. The sliding block 15 prevents the cargo base plate 13 from slipping off the platform cargo track 2. When the cargo base plate 13 is positioned in the appropriate position, the first sliding hole 27 fixedly connected to the inner side of the sliding groove 19 will be activated. The activation of the first sliding hole 27 will push the platform 21 to move horizontally along the sliding groove 19. The movement of the platform 21 will contact the cargo box that is in contact with the outer side of the force-bearing column 4. During the movement of the platform 21, because the stabilizer 25 is connected to the U-shaped block 24 and the fixed axis 23, the platform 25 is connected to the platform 23. When the platform 21 is pushed outward, the U-shaped block 24 and the stabilizer bar 25 will move downward due to gravity. The U-shaped block 24 will rotate outside the fixed axis 23. The protective block 26 can protect the stabilizer bar 25. When the platform 21 is retracted due to the action of the telescopic cylinder 20, the U-shaped block 24 and the stabilizer bar 25 will contact the outside of the cargo floor 13 and return to the second cavity 22 opened on the outside of the platform 21. The hollow tube 17 will slide inside the first sliding hole 27, and the L-shaped block 14 will slide inside the second sliding hole 28.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
