Description

Technical Field

[0001] The utility model relates to the technical field of logistics transportation, and more specifically, to a logistics loading and unloading platform. Background Technique

[0002] Logistics originally meant "physical distribution" or "goods distribution", which is part of the supply chain activities. It is a process of planning, implementing, and controlling the efficient and low-cost flow and storage of goods, services, consumption, and related information from the place of origin to the place of consumption. Logistics centers around warehousing to promote the synchronization of production and the market. Logistics is to meet the needs of customers, with the lowest cost, through transportation, storage, distribution, etc., to realize the whole process of planning, implementation, and management of raw materials, semi-finished products, finished products, and related information from the place of origin of goods to the place of consumption of goods.

[0003] During the logistics transportation process, a loading and unloading platform is needed to play a bridging role between the vehicle and the loading and unloading platform, ensuring the smooth and safe transmission of goods between the vehicle and the conveyor line. However, the existing loading and unloading platform has a relatively fixed structure, and there are also differences in the carriage widths of different logistics transportation vehicles, resulting in the inability to adjust the use width of the loading and unloading platform according to actual use needs, making it easy for goods to fall during the loading and unloading process, and there are certain defects in use.

[0004] In view of this, we propose a logistics loading and unloading platform. Content of the Utility Model

[0028] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0029] A logistics loading and unloading platform includes a base 1. There is a loading and unloading table 2 on the upper side of the base 1. An inner groove 3 is opened inside the loading and unloading table 2. Storage grooves 17 are arranged on both sides of the inner groove 3. A movable plate 7 is movably arranged inside the two groups of storage grooves 17. The movable plate 7 movably penetrates through the storage grooves 17 and extends to the outside. And a threaded rod 4 is rotatably arranged inside the inner groove 3. Two sections of threads with opposite directions are arranged on the outside of the threaded rod 4. And threaded blocks 5 are sleeved on the two sections of threads with opposite directions on the outside of the threaded rod 4. Support blocks 6 are rotatably arranged on both sides of the two groups of threaded blocks 5. The support blocks 6 are rotatably connected to the movable plate 7. The threaded rod 4 movably penetrates through the loading and unloading table 2 and extends to the outside. And a connection disk 8 is fixedly arranged on the part of the outer side end of the threaded rod 4 located outside the loading and unloading table 2. By rotating the connection disk 8 in different directions, the movable plate 7 can be driven to move in different directions, so that while facilitating the adjustment of the use width of the loading and unloading table 2, it is also convenient for storage, improving the use flexibility.

[0030] Specifically, a hydraulic cylinder 9 is arranged on the upper side of the base 1. An installation block 18 is fixedly arranged on the lower side of the loading and unloading table 2. One end of the hydraulic cylinder 9 is connected to the base 1, and the other end of the hydraulic cylinder 9 is connected to the installation block 18. By turning on the hydraulic cylinder 9 through an external power source, the use height of the device can be conveniently adjusted, so as to meet various use requirements.

[0031] Furthermore, sliding blocks 10 are fixedly arranged on both sides of the movable plate 7. Chute grooves 11 for docking the sliding blocks 10 are opened on both sides of the storage grooves 17. When the movable plate 7 moves, the sliding blocks 10 are driven to slide in the chute grooves 11, so as to facilitate the movement of the movable plate 7 while improving the use stability of the movable plate 7.

[0032] It should be noted that an L-shaped block 12 is fixedly arranged on the outside of the loading and unloading table 2. A positioning rod 13 is movably arranged on the outside of the L-shaped block 12. A connection head 14 is fixedly arranged on the outer side end of the positioning rod 13. And the other end of the positioning rod 13 movably penetrates through the L-shaped block 12 and extends to the inside. A plurality of positioning holes 15 for docking the positioning rod 13 are opened through the outside of the connection disk 8. The positioning rod 13 is movably inserted into the positioning holes 15, so as to facilitate the rotation of the connection disk 8 while also facilitating the fixation of the connection disk 8, thus ensuring the use flexibility and use stability of the connection disk 8.

[0033] It should be noted that a spring 16 is sleeved on the outside of the positioning rod 13. One end of the spring 16 is connected to the connection head 14, and the other end of the spring 16 is connected to the L-shaped block 12. The spring 16 does not deform in the initial state. When rotating the connection disk 8, the positioning rod 13 needs to be pulled out from the positioning hole 15. At this time, the spring 16 is stretched and deformed. When it is necessary to fix the connection disk 8, through the release of the elastic potential energy of the spring 16, the positioning rod 13 can be driven to quickly insert into the positioning hole 15, improving the insertion convenience and insertion stability.

[0034] In addition, a conical head 20 is fixedly arranged on the lower side of the movable plate 7, and a telescopic rod 21 is rotatably arranged on the outer side of the conical head 20. Fixed blocks 19 are fixedly arranged on both sides of the mounting block 18, and the other end of the telescopic rod 21 is rotatably connected to the fixed block 19. By arranging the telescopic rod 21, while facilitating the movement of the movable plate 7, it can provide a certain support for the movable rod 7, thereby improving the support stability of the movable plate 7.

[0035] It has to be said that limit blocks 22 are fixedly arranged on both sides of the threaded block 5, and limit grooves 23 for docking the limit blocks 22 are formed on both sides of the inner groove 3. When the threaded rod 4 is rotated, it can drive the limit blocks 22 to slide in a limited manner in the limit grooves 23, thereby driving the threaded block 5 to move parallel along the threaded rod 4, so that it can push the movable plate 7 to move parallel.

[0036] Working principle: First, move the whole device to a suitable position, then lock the moving wheels of the device, then pull the connecting head 14 outwards to drive the positioning rod 13 to move. The positioning rod 13 moves out of the positioning hole 15 and stretches the spring 16. Then rotate the connecting disc 8 to drive the threaded rod 4 to rotate. When the threaded rod 4 rotates, the two threaded blocks 5 sleeved on the outer side of the threaded rod 4 move along the threaded rod 4 simultaneously and approach each other under the limited cooperation of the limit blocks 22 and the limit grooves 23. When the threaded blocks 5 move, they drive the support blocks 6 on both sides to move. The movable plate 7 is pushed outwards from the storage groove 17 through the support blocks 6 until the movable plate 7 moves to a suitable position. Finally, release the connecting head 14. At this time, the spring 16 resets and contracts, driving the positioning rod 13 to be inserted into the positioning hole 15 again, thereby facilitating the fixation of the connecting disc 8 and ensuring the use stability of the movable plate 7.
