Description

Technical Field

[0001] The utility model relates to the technical field of pallet transportation, in particular to a transportation steering structure for pallet transportation. Background Art

[0002] Pallet transportation is a mode of transportation in which goods are loaded onto standard pallets according to certain requirements to form a transport unit, which is convenient for loading, unloading, transporting and stacking using a forklift or pallet lift. The main advantages of this method include improving the efficiency of cargo handling and loading and unloading, facilitating sorting, reducing cargo damage and loss, and relatively small investment and quick results.

[0003] When using pallets for transporting goods, the goods are mainly piled up on the pallets. The pallets are mainly transported by using the slots at the bottom for lifting by forklifts. The pallet is also turned passively after being lifted by forklifts. On this basis, if there is a problem with the orientation of the pallet after it is placed in the specified position, it is impossible to make a quick steering adjustment because the pallet itself has no steering structure. The pallet can only be lifted by a forklift and then steered by the forklift to achieve the purpose of passive steering, which is relatively troublesome to operate. Utility Model Content

The central shaft 21 is located in the driving groove 12 and a worm wheel 22 is fixed at one end. A connecting shaft 15 is rotatably connected in the driving groove 12, and a worm 13 is fixed on the connecting shaft 15. The worm wheel 22 and the worm 13 are meshed. The end of the connecting shaft 15 extends through the tray body 1 and is fixed with a rocker 14. A support ring 16 is fixed on the upper end of the tray body 1, and balls 17 are equidistantly installed on the upper end of the support ring 16. The upper end of the ball 17 is against the bottom of the carrying plate 2.

[0019] The positioning assembly includes a card plate 4, which is slidably connected to the side wall of the tray body 1 and is located at both ends of the side frame 3. The end of the card plate 4 is an L-shaped structure and is clamped at both ends of the side frame 3. A telescopic groove 41 is opened in the side wall of the tray body 1 and at a position corresponding to the card plate 4. A telescopic block 42 is slidably connected in the telescopic groove 41. A threaded rod 43 is rotatably connected in the telescopic groove 41. The threaded rod 43 passes through the telescopic groove 41 and is threadedly connected to the telescopic block 42. The end of the threaded rod 43 extends through the telescopic groove 41, and one end of the threaded rod 43 extends out of the fixed rod with a rotating plate 44.

[0020] Working principle: When the side frame 3 remains upright, the extended telescopic rod 31 abuts against the side of the load-bearing plate 2, which can effectively prevent the load-bearing plate 2 from rotating, thereby ensuring stability during transportation. After the side frame 3 is flipped over, the telescopic rod 31 will lose its blocking effect, and the load-bearing plate 2 can rotate freely. At this time, the rocker 14 is used to drive the connecting shaft 15 and the worm 13 to rotate, so as to realize the rotation of the worm wheel 22, and finally drive the central shaft 21 and the load-bearing plate 2 to rotate, so as to realize the purpose of autonomous rotation of the load-bearing plate 2. After the pallet body 1 falls to the ground, the direction of the goods can be changed by rotating its own load-bearing plate 2. During the whole process, the load-bearing plate 2 rotates to the specified position, which can be The positioning is achieved by utilizing the one-way transmission of the worm 13 and the worm wheel 22. At the same time, after rotating to the specified position, the side frame 3 is kept upright and fixed. At this time, the unblocked telescopic rod 31 still extends out of the side frame 3 under the push of the telescopic spring 32, and the telescopic rod 31 aligned with the side of the supporting plate 2 will block the rotation of the supporting plate 2, thereby achieving the purpose of further positioning. When positioning the side frame 3, it is only necessary to use the rotating plate 44 to rotate the threaded rod 43, thereby realizing the telescopic drive of the telescopic block 42, and finally driving the card plate 4 to slide. After the side frame 3 is flipped to the upright state, the card plate 4 moves to the adjacent side, and the two sides of the side frame 3 can be clamped and fixed. The overall operation is simple and convenient.
