[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figure 1-2 This utility model provides a technical solution: a large-scale material logistics transfer vehicle.

[0025] To address the issue described above, which is that AGVs deliver goods in a single intelligent delivery cycle, resulting in low efficiency and high requirements for the positioning of the delivered goods, it is necessary to equip the docking position with corresponding limiting devices to fix the pallet.

[0026] The solution is as follows: A large material logistics transfer vehicle includes: a vehicle body 1, wherein a limit device 2 is provided on the side of the vehicle body 1 and a lifting device 3 is provided at the bottom, a wheel assembly 4 is provided at the lower part of the lifting device 3, the limit device 2 includes pedals 5 and a rotating shaft 9 is provided between the pedals 5, a stop block 10 is provided on the side of the rotating shaft 9 and a limit link 11 is connected to the side of the stop block 10, a spring 12 is provided on the side of the limit link 11, a link bracket 13 is provided on the side of the spring 12 and a transition link 14 is provided on the side of the link bracket 13. The adapter link 14 has a collision block 15 on its side. The lifting device 3 includes a hydraulic cylinder 16, and a horizontal link 17 is provided at the power output end of the hydraulic cylinder 16, which is in contact with the horizontal link 17. Lifting links 18 are installed at both ends of the horizontal link 17. A pressing block is provided at the power output end of the hydraulic cylinder 16, and a pressing link 20 is provided on the side of the pressing block. A steel wire rope 21 is provided at the end of the pressing link 20. One end of the steel wire rope 21 is tied to the round rod of the vehicle body 1, and the other end is connected to the foot pedal link 22. The side of the vehicle body 1 is equipped with... The vehicle is equipped with a pallet limiting device 2 and a lifting device 3 installed below the vehicle body 1. A wheel assembly 4 is installed below the lifting device 3. When the trailer reaches the designated position, the pedal 5 of the limiting device 2 is pressed, causing the telescopic pin 6 to move downwards. Simultaneously, the rotating shaft 9 rotates, and the stop block 10 on the rotating shaft 9 rotates. After the stop block 10 rotates to a certain angle, it contacts the limiting linkage 11 and moves backwards, compressing the spring 12 of the limiting linkage 11. When the stop block 10 moves to a certain angle, it disengages from the limiting linkage 11, and the spring 12 resets the limiting linkage 11, locking the stop block 10 and thus locking the pedal 5. When goods are loaded onto the vehicle, the pallet impacts the collision block 15. The collision block 15 drives the connecting rod 14, which pulls the limiting rod 11 back, causing the limiting rod 11 to disengage from the stop block 10. The rotating shaft 9 is in a free state, and the tension spring 7 pulls the telescopic pin 6, causing it to extend and limit the goods. After the goods are loaded onto the vehicle, the foot pedal 22 is stepped on continuously. The foot pedal 22 pulls the wire rope 21, which causes the pressing rod 20 to move. The pressing rod 20 contacts the pressing block of the hydraulic cylinder 16, and the hydraulic cylinder 16 pushes out, driving the horizontal connecting rod 17 and the lifting connecting rod 18 to move, thereby raising the transfer vehicle.When the hook 23 is subjected to lateral force, the hook 23 drives the first connecting rod 24, which pulls the rotating seat 25 to rotate. The rotating seat 25 drives the wheel body 26 to rotate. At the same time, the rotating seat 25 pulls the second connecting rod 28, which drives the turntable 29 to rotate, thereby pulling the wheel system on the other side, thus linking the wheels together. The pallet of the logistics transfer vehicle can be manually pushed onto the trailer from the side, which is convenient and quick. The trailer is equipped with hooks 23 at the front and rear, and multiple trailers can be combined to form a group to deliver multiple goods at once, improving delivery efficiency. The trailer is equipped with a lifting mechanism. After the pallet is in place, the vehicle body is raised, which can lift the pallet off the ground and prevent the pallet from contacting the ground during transportation. The trailer's traveling wheels are linked by a linkage to ensure that all four sets of wheels move simultaneously, reducing the turning radius of the trailer. It is equipped with a limit device 2 to prevent the pallet from being pulled out of the trailer during transportation.

[0027] Further improvements, such as Figure 3 As shown: The hydraulic cylinder 16 is a manual hydraulic cylinder 16 and there are three sets of it. The manual hydraulic cylinder 16 makes the operation simpler, does not require an external power source, and is suitable for various environments. At the same time, the three sets of hydraulic cylinders 16 enhance the stability and load-bearing capacity of the transfer vehicle, ensuring that the pallet is stable and safe during the lifting process.

[0028] Further improvements, such as Figure 2 As shown: The vehicle body 1 is provided with a guide block 8 and the corresponding position of the pedal 5 is provided with a telescopic pin 6. The telescopic pin 6 is connected to the guide block 8. The surface of the telescopic pin 6 is provided with a tension spring 7. When the pedal 5 is pressed, it can more accurately trigger the limiting device 2. At the same time, the tension spring 7 ensures that the telescopic pin 6 can automatically return to its original position when no force is applied, which increases the reliability and durability of the limiting device 2.

[0029] Further improvements, such as Figure 4 As shown: The end of the lifting link 18 is equipped with a roller 19 and the roller 19 is rotatably connected to the lifting link 18. The design of the roller 19 reduces the friction between the lifting link 18 and the vehicle body 1 during the lifting process, reduces wear, and extends service life.

[0030] Further improvements, such as Figure 5 As shown: The wheel assembly 4 includes a wheel bracket 27 and a rotating seat 25 is provided at the lower part of the wheel bracket 27. The wheel body 26 is provided at the lower part of the rotating seat 25. A second connecting rod 28 is provided on the side of the rotating seat 25, and a turntable 29 is provided between the two sets of second connecting rods 28 arranged opposite to each other. The wheels can be linked by the connecting rods to ensure that the four sets of wheels move at the same time, thereby reducing the turning radius of the trailer and improving the flexibility and ease of operation of the trailer.

[0031] Further improvements, such as Figure 5As shown: The wheel bracket 27 is provided with a first connecting rod 24 inside, and the side of the first connecting rod 24 is connected to the rotating seat 25. The side of the first connecting rod 24 is provided with a tow hook 23. The design of the tow hook 23 allows multiple trailers to be easily assembled into a vehicle group, realizing the delivery of multiple goods at one time and improving delivery efficiency.

[0032] Working principle: The vehicle body 1 of this utility model has a pallet limiting device 2 installed on its side, and a lifting device 3 installed below the vehicle body 1. Below the lifting device 3 is a wheel assembly 4. When the trailer reaches the designated position, the pedal 5 of the limiting device 2 is pressed down, causing the telescopic pin 6 to move downwards. Simultaneously, the rotating shaft 9 rotates, and the stop block 10 on the rotating shaft 9 rotates. After the stop block 10 rotates to a certain angle, it contacts the limiting linkage 11 and causes it to retract, compressing the spring 12 of the limiting linkage 11. When the stop block 10 moves to a certain angle, it contacts the limiting linkage 12. When the limiting link 11 disengages, the spring 12 resets the limiting link 11, and the stop block 10 is locked, thus locking the pedal 5. When goods are loaded, the pallet impacts the collision block 15, which drives the connecting link 14 to pull the limiting link 11 back, causing the limiting link 11 to disengage from the stop block 10. The rotating shaft 9 is in a free state, and the tension spring 7 pulls the telescopic pin 6, causing it to extend and limit the goods. After the goods are loaded, the foot pedal link 22 is continuously stepped on, which pulls the steel wire rope 21, thereby pressing the pedal. When link 20 moves, pressing link 20 contacts the pressing block of hydraulic cylinder 16, causing hydraulic cylinder 16 to push out, driving horizontal link 17 and lifting link 18 to move, thereby raising the transfer vehicle; when tow hook 23 is subjected to lateral force, tow hook 23 drives first link 24, first link 24 pulls rotating seat 25 to rotate, rotating seat 25 drives wheel body 26 to rotate, and at the same time rotating seat 25 pulls second link 28, second link 28 drives turntable 29 to rotate, thereby pulling the wheel system on the other side, thus raising the vehicle. The trailer features a wheel linkage system, allowing pallets to be manually pushed onto the trailer from the side for quick and easy transport. It is equipped with tow hooks 23 at the front and rear, enabling multiple trailers to form a fleet for transporting multiple goods at once, thus improving efficiency. The trailer also features a lifting mechanism that raises the vehicle after the pallet is in place, preventing it from contacting the ground during transport. The trailer's wheels are linked by a linkage system, ensuring all four wheels move simultaneously, reducing the trailer's turning radius. A limit device 2 is also included to prevent pallets from slipping out of the trailer during transport.
