All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] Please see Figure 1-11 An embodiment of this utility model provides: a pallet for an unmanned laser forklift, including a pallet body 1 and a base frame 2. The base frame 2 is provided at the top of the pallet body 1, and a roller conveyor 3 is provided at the top of the base frame 2. A lifting frame 4 is provided at the middle position above the roller conveyor 3. A rotating shaft 34 is installed at the bottom end of the lifting frame 4. A base 5 is installed at the center position of the top of the base frame 2 below the rotating shaft 34. Clamping frames 6 are symmetrically installed inside the pallet body 1. An upper support shaft 7 is movably installed at the center position of the top of each clamping frame 6. A torsion spring 8 is fitted on the outer wall of each upper support shaft 7. One end of each torsion spring 8 is connected to the upper support shaft 7, and the other end of each torsion spring 8 is connected to the clamping frame 6. A slide rail 11 is installed at the bottom end of each clamping frame 6.

[0030] Gears 9 are installed at the bottom of the upper support shaft 7 on one side of the slide rail 11. Gear racks 10 are symmetrically slidably installed at the bottom of the clamping frame 6 on one side of the gear 9, and the racks 10 mesh with the gears 9.

A clamping arm 14 is installed at the bottom of the sliding arm 12 on the side away from the rack 10, and a clamping bracket 15 is installed at the bottom of the clamping arm 14.

[0031] By operating the unmanned laser forklift to move to one side of the pallet body 1, and controlling the unmanned laser forklift to extend its forks between the two sets of clamps 15, the forks of the unmanned laser forklift move the two sets of clamps 15 to both sides. Under the support of the clamping frame 6, the clamps 15 on both sides drive the clamping arms 14 to move, and the clamping arms 14 on both sides drive the sliding arms 12 to move. The sliding arms 12 drive the slide block 13 to slide along the surface of the slide rail 11. Under the meshing action of the rack 10 and the gear 9, the rack 10 drives the gear 9 to rotate. At the same time, the gear 9 drives the upper support shaft 7 to rotate synchronously. When the clamps 15 on both sides move to a certain position, under the torsional elastic action of the torsion spring 8, a reverse elastic force is provided to make the two sets of clamps 15 and the forks of the unmanned laser forklift in close contact. This achieves close contact between the pallet and the forks of the unmanned laser forklift, and improves the stability of the contact between the forks and the pallet.

[0032] At the corner positions on the outer wall of the roller conveyor 3, there are clamping seats 28. On the outer wall of the base frame 2 below the clamping seats 28, there are bushings 29. At the bottom of the clamping seats 28 above the bushings 29, there are clamping shafts 30. The clamping shafts 30 are slidably connected to the bushings 29. At the bottom of the base 5 on one side of the rotating shaft 34, there is a stepper motor 18. The stepper motor 18 plays the role of power drive. At the output end of the stepper motor 18, there is a transmission sprocket 19.

On the outer wall of the upper transmission shaft 16, there is a support sprocket 17. On the outer wall of the transmission sprocket 19 on one side of the support sprocket 17, there is a chain 20. The chain 20 extends to the surface of the support sprocket 17.

[0033] A horizontal shaft 25 is symmetrically and movably installed on the inner wall of the base frame 2 below the roller conveyor 3. Support seats 27 are movably installed at both ends of the horizontal shaft 25, and the support seats 27 are fixedly connected to the base frame 2. A rotating frame 24 is symmetrically fitted on the outer wall of the horizontal shaft 25. A pulley 26 is movably installed at the top of the rotating frame 24, and the pulley 26 is slidably connected to the roller conveyor 3. A cylinder 21 is symmetrically and movably installed inside the base frame 2 on one side of the rotating frame 24. The cylinder 21 plays the role of power drive. A lower drive shaft 22 is installed at the output end of the cylinder 21. An eccentric block 23 is movably installed at the end of the lower drive shaft 22 away from the cylinder 21. A right support shaft 32 is movably installed at the end of the eccentric block 23 close to the lower drive shaft 22, and the eccentric block 23 is connected to the lower drive shaft 22 through the right support shaft 32.

[0034] Left support shafts 33 are movably installed on the outer wall of the eccentric block 23 on one side of the rotating frame 24, and the eccentric block 23 is movably connected to the rotating frame 24 through the left support shaft 33. A remote controller 31 is installed on the outer wall of the base frame 2 above the pallet body 1, and the output end of the remote controller 31 is electrically connected to the input end of the roller conveyor 3, the stepper motor 18, and the cylinder 21.

[0035] The conveyor rollers inside the roller conveyor 3 facilitate the support and transport of items. When the items are transported to the top of the lifting frame 4 and their orientation needs to be adjusted, the cylinder 21 is activated by operating the remote controller 31. With the support of the base frame 2, the cylinder 21 drives the lower drive shaft 22 to move. The lower drive shaft 22 drives the eccentric block 23 to move via the right support shaft 32. The eccentric block 23 drives the rotating frame 24 to rotate via the left support shaft 33. The rotating frame 24 drives the pulley 26 to rotate around the horizontal axis 25. The support seat 27 provides movable support for the horizontal axis 25. The pulley 26 slides at the bottom of the roller conveyor 3 to facilitate the downward movement of the roller conveyor 3. The roller conveyor 3 drives the clamp seat 28 and the clamp shaft 30 to move synchronously. The clamp shaft 30 slides inside the bushing 29 to ensure the stable downward movement of the roller conveyor 3. At this time, the roller conveyor 3 and the lifting frame 4 are not on the same horizontal plane. Above, the lifting frame 4 independently supports the items. By operating the remote controller 31 to turn on the stepper motor 18, under the support of the base 5, the stepper motor 18 drives the transmission sprocket 19 to rotate. The transmission sprocket 19 drives the chain 20 to move, and the chain 20 drives the support sprocket 17 to rotate. At the same time, the support sprocket 17 drives the upper transmission shaft 16 to rotate, and the upper transmission shaft 16 drives the rotating shaft 34 to rotate. The rotating shaft 34 drives the lifting frame 4 and the items conveyed on it to rotate synchronously, so as to facilitate the adjustment of the direction of the items. After the direction of the items is adjusted, the remote controller 31 is operated to turn on the cylinder 21. The cylinder 21 drives the roller conveyor 3 to reset. At this time, the conveying roller inside the roller conveyor 3 lifts the items again for conveying. This realizes the convenient rotation adjustment and conveying of items by the unmanned laser forklift using a pallet, which facilitates the automatic rotation of items for conveying in a certain direction and improves the convenience of adjusting the conveying direction of items.

[0036] Working principle: In use, an external power supply is connected. The unmanned laser forklift is controlled to extend its forks between the two sets of clamps 15. At this time, the forks of the unmanned laser forklift move the two sets of clamps 15 to both sides. Under the support of the clamping frame 6, the clamps 15 on both sides drive the clamping arms 14 to move. The clamping arms 14 on both sides drive the sliding arms 12 to move. The sliding arms 12 drive the slide block 13 to slide along the surface of the slide rail 11. The rack 10 drives the gear 9 to rotate. At the same time, the gear 9 drives the upper support shaft 7 to rotate synchronously. When the two After the side clamps 15 move to a certain position, the torsion spring 8 provides a reverse elastic force to ensure that the two clamps 15 are in close contact with the forks of the unmanned laser forklift. The conveying rollers inside the roller conveyor 3 facilitate the support and transport of items. The cylinder 21 drives the lower drive shaft 22 to move. The lower drive shaft 22 drives the eccentric block 23 to move via the right support shaft 32. The eccentric block 23 drives the rotating frame 24 to rotate via the left support shaft 33. The rotating frame 24 drives... Pulley 26 rotates around horizontal shaft 25 and slides at the bottom of roller conveyor 3 to facilitate downward movement of roller conveyor 3. Roller conveyor 3 drives clamp seat 28 and clamp shaft 30 to move synchronously. Clamp shaft 30 slides inside bushing 29 to make roller conveyor 3 move downward stably. At this time, roller conveyor 3 and lifting frame 4 are not on the same horizontal plane. Lifting frame 4 independently supports the items. Stepper motor 18 drives transmission sprocket 19 to rotate. Transmission sprocket 19 drives chain 20 to move. Chain 20 drives support sprocket 17 to rotate. At the same time, support sprocket 17 drives upper transmission shaft 16 to rotate. Upper transmission shaft 16 drives rotating shaft 34 to rotate. Rotating shaft 34 drives lifting frame 4 and the items conveyed on it to rotate synchronously to facilitate adjustment of the item's direction. After the item's direction is adjusted, cylinder 21 drives roller conveyor 3 to reset. At this time, the conveying roller inside roller conveyor 3 lifts the item again for conveying to complete the use of the pallet.
