[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners.

[0029] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0030] As Figures 1 - 9 shown, a four-way vehicle handling anti-falling structure includes a four-way vehicle main body 1, a tray 2, a rotary table 11, and a frame 4. The tray 2 is located above the rotary table 11, the rotary table 11 is located on the upper surface of the four-way vehicle main body 1, the frame 4 is fixedly installed on the upper surface of the four-way vehicle main body 1, both sides of the outer wall of the rotary table 11 are fixedly provided with support plates 12, and both sides inside the frame 4 are connected to the support plates 12 through a driving mechanism provided. Anti-falling cargo clamping mechanisms are arranged inside both of the two support plates 12;

[0031] The anti-falling cargo clamping mechanism is arranged on both sides of the rotary table 11 and is used to fix the stacked high goods to prevent the goods from falling;

[0032] As Figure 1 , Figure 2 , Figure 4 shown, the four-way vehicle main body 1 is a logistics four-way shuttle vehicle in the prior art, and the rotary table 11 is used as a frame body with multiple groups of rotating rollers arranged inside. It is a well-known technology and will not be elaborated here too much.

[0033] The driving mechanism includes a lead screw 15 rotatably installed in the middle inside the frame 4. A first motor 5 is provided at the upper end of the lead screw 15, and the first motor 5 is fixedly arranged above the frame 4. Guide rods 14 are fixedly arranged on both sides of the lower end face of the frame 4. Stabilizing rods 10 are fixedly sleeved on the outer sides of the two guide rods 14 above. The support plate 12 is in threaded cooperation with the lead screw 15, and the two ends of the support plate 12 away from the lead screw 15 are in sliding cooperation with the guide rods 14;

[0034] As Figure 1 , Figure 2 and Figure 3 shown, the first motor 5 above the frame 4 can drive the lead screw 15 to rotate, so that the support plate 12 can move outside the guide rods 14, thereby lifting the roller table 11 and the tray 2, and then meeting the requirement of the forklift to fork the tray 2 above the low track.

[0035] The anti-falling and cargo-locking mechanism includes an assembly seat 28 slidably installed inside the angle plate 3. Inside the assembly seat 28, a support block 26 is connected through a fixedly arranged arc-shaped rod 38, and elastic pressing mechanisms are arranged on both outer sides of the outer wall of the support block 26;

[0036] As Figure 1 , Figure 2 and Figure 6 shown, the assembly seat 28 can be connected to the support block 26 on the other side through the arc-shaped rod 38, so that the elastic pressing mechanism can be used inside the assembly seat 28.

[0037] The elastic pressing mechanism includes a frame shell 40 fixedly installed on one side of the outer wall of the support block 26. A pressing block 27 is slidably installed inside the frame shell 40. A sliding cylinder 41 is fixedly arranged on the outer wall of the pressing block 27. A sliding rod 39 is slidably installed inside the sliding cylinder 41. A second spring 42 is arranged outside the sliding rod 39. An L-shaped frame 32 is fixedly arranged on the upper end face of the frame shell 40. One end of the sliding rod 39 away from the sliding cylinder 41 is fixedly connected to the outer wall of the L-shaped frame 32;

[0038] As Figure 6 , Figure 7 and Figure 9 shown, under the pressing of the sliding cylinder 41 and the second spring 42, the pressing block 27 can press against the outer wall of the tray 2 to fix the tray 2.

[0039] On the upper end faces of both groups of L-shaped frames 32, support rods 25 are vertically arranged. Above the two support rods 25, a stabilizing platform 23 is commonly installed. Inside both groups of stabilizing platforms 23, hydraulic cylinders 22 are fixedly installed. The telescopic ends of the hydraulic cylinders 22 are fixedly provided with a pressing frame 34. On the outer surface of the pressing frame 34, pressing seats 33 are installed at equal intervals in the vertical direction. On the lower end face of the pressing frame 34, a moving assembly is provided. The moving assembly includes a sleeve 24 fixedly arranged on the lower end face of the pressing frame 34. Inside the sleeve 24, a first spring 35 is arranged. Inside the sleeve 24 and at the lower end of the first spring 35, a T-shaped rod 37 is slidably installed. On both sides of the end of the T-shaped rod 37 away from the sleeve 24, rollers 36 are rotatably installed.

[0040] As Figure 6 , Figure 7 and Figure 8 shown, the hydraulic cylinder 22 can cause the pressing frame 34 to move towards one end. Thus, the sleeve 24 and the lower T-shaped rod 37 will be elastically pressed by the first spring 35 inside, causing the rollers 36 to roll and press above the tray 2. This not only enables the pressing frame 34 to fix the goods but also allows the rollers 36 to be positioned above the tray 2.

[0041] On one side of the outer wall of the assembly seat 28, a connecting rod 31 is fixedly arranged. At the end of the connecting rod 31 away from the assembly seat 28, a slider 29 is fixedly arranged. Inside the slider 29, a screw rod 30 is threaded. The screw rod 30 is rotationally matched with the angle plate 3, and one end of the screw rod 30 is fixedly provided with a third motor 21. The third motor 21 is fixedly arranged inside one side of the angle plate 3 through a housing frame 20 fixedly sleeved outside.

[0042] As Figure 7 shown, the third motor 21 can drive the screw rod 30 to rotate, and then make the corresponding slider 29 slide downward from the upper part inside the angle plate 3, causing the abutting block 27 to be able to approach the lower part of the outer wall of the tray 2, so as to prevent the tray 2 from moving during transportation.

[0043] On the upper end face of the support rod 25, a connecting rod 13 is fixedly arranged. At the end of the connecting rod 13 away from the support rod 25, a net bag 9 is connected through an elastic rope 8. Above the inside of the frame 4, two support rods 7 are respectively arranged. Above one of the support rods 7, a second motor 6 is fixedly arranged. The output end of the second motor 6 is fixedly provided with a rotating drum 19. A traction rope 16 is wound around the outer surface of the rotating drum 19. The end of the rotating drum 19 away from the second motor 6 is rotatably connected to a bearing platform 17. The bearing platform 17 is installed on the upper surface of the support rod 7 at the end away from the second motor 6. The lower end of the traction rope 16 is fixedly provided with a fixing seat 18. The lower end of the fixing seat 18 is connected to the middle of the outer surface of the net bag 9.

[0044] As Figure 1 , Figure 2 and Figure 5As shown, the support rod 25 is connected to the bag net 9 through the connecting rod 13 and the elastic rope 8 on the upper end surface, so as to stretch the maximum area of ​​the bag net 9 when transporting high goods, and then cover the outside of the goods, so as to prevent the goods from falling during transportation, and at the same time, the bag net 9 can be reasonably rolled up;

[0045] The second motor 6 retracts and releases the traction rope 16 by rotating the rotating drum 19 to store the bag net 9. When the bag net 9 is rolled up, the support rod 25 will be away from the goods, and the fixed seat 18 will pull the bag net 9 upward. Under the elastic extension of the elastic rope 8, the bag net 9 will not contact the goods when being pulled upward.

[0046] Working principle: When in use, higher goods can be stacked on the top of the pallet 2 and transported above the four-way vehicle body 1. When the four-way vehicle body 1 transports goods, in order to ensure that the goods do not fall and the pallet 2 does not move, the third motor 21 at both ends of the angle plate 3 can drive the slider 29 to move, and the slider 29, the connecting rod 31, and the assembly seat 28 move from the upper part of the inside of the angle plate 3 to the lower part until the stop block 27 inside the frame shell 40 presses against the outer wall of the pallet 2. At the same time, the support rod 25 will also move with the assembly seat 28, prompting the roller 36 at the lower end to roll to the edge of the upper end surface of the pallet 2. When the roller 36 rolls to the upper end surface of the pallet 2, it will squeeze the first spring 35 inside the sleeve 24, and then after the stop block 27 presses against the outer wall of the pallet 2, the roller 36 stays on the upper end surface of the pallet 2 due to the elastic pressure of the first spring 35, and then fixes the pallet 2 above and on the side of the pallet 2, so as to avoid The problem of displacement of the pallet 2 occurs due to braking and steering during the movement of the four-way vehicle body 1. The hydraulic cylinder 22 inside the stabilizing platform 23 can drive the support frame 34 to approach the goods stacked above the pallet 2, causing the multiple groups of support seats 33 on the outer surface of the support frame 34 to contact the goods. After the support rod 25 moves, the corresponding bag net 9 and elastic rope 8 will cover the outside of the higher stacked goods, so as to ensure that the goods will not fall during transportation. After being transported to the forklift position, the first motor 5 drives the screw rod 15 to rotate, causing the support plate 12 to slide on the outside of the guide rod 14 and the screw rod 15, and then the roller table 11 and the pallet 2 are lifted. The bag net 9 is also in the process of moving. Through the winding of the second motor 6 at the frame rod 7, the bag net 9 is pulled upward to avoid the entanglement of the goods with the bag net 9. After the roller table 11 is lifted, the fork arm of the forklift can penetrate into the bottom of the pallet 2, and then the goods on the pallet 2 are forked.

[0047] The above has shown and described the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and all these changes and improvements fall within the scope of the present invention claimed.
