It is a well-known technology and will not be described in detail here.

[0021] The driving mechanism includes a screw rod 15 rotatably mounted in the middle of the frame 4, a first motor 5 is arranged on the upper end of the screw rod 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 surface of the frame 4, and a stabilizing rod 10 is fixedly sleeved on the upper part of the two guide rods 14. The support plate 12 is threadedly matched with the screw rod 15, and the two ends of the support plate 12 away from the screw rod 15 are slidably matched with the guide rods 14; like Figure 1 , Figure 2 and Figure 3 As shown, the first motor 5 can drive the screw 15 to rotate above the frame 4, so that the support plate 12 can move outside the guide rod 14, so as to lift the roller table 11 and the pallet 2, thereby satisfying the forklift to fork the pallet 2 above the low track.

[0022] The anti-falling and jamming mechanism includes an assembly seat 28 slidably mounted inside the angle plate 3, the assembly seat 28 is connected to a support block 26 via a fixed arc rod 38, and both sides of the outer wall of the support block 26 are provided with elastic pressing mechanisms; like Figure 1 , Figure 2 and Figure 6 As shown, the assembly seat 28 can be connected to the support block 26 on the other side through the arc rod 38, so that the elastic pressing mechanism can be used inside the assembly seat 28.

[0023] The elastic pressing mechanism includes a frame shell 40 fixedly mounted on one side of the outer wall of the support block 26, a stop block 27 is slidably mounted inside the frame shell 40, a slide cylinder 41 is fixedly mounted on the outer wall of the stop block 27, a slide rod 39 is slidably mounted inside the slide cylinder 41, a second spring 42 is arranged outside the slide rod 39, an L-shaped frame 32 is fixedly arranged on the upper end surface of the frame shell 40, and one end of the slide rod 39 away from the slide cylinder 41 is fixedly connected to the outer wall of the L-shaped frame 32; like Figure 6 , Figure 7 and Fig. 9 As shown, the stopper 27 can be pressed against the outer wall of the tray 2 under the pressure of the slide 41 and the second spring 42 to fix the tray 2.

[0024] The upper end surfaces of the two groups of L-shaped frames 32 are vertically provided with support rods 25, and a stabilizing platform 23 is installed on the upper outside of the two support rods 25. The hydraulic cylinders 22 are fixedly installed inside the two groups of stabilizing platforms 23. The extension end of the hydraulic cylinder 22 is fixedly provided with a support frame 34. The outer surface of the support frame 34 is provided with a support seat 33 at equal distances in the vertical direction. The lower end surface of the support frame 34 is provided with a moving component, which includes a sleeve 24 fixedly provided on the lower end surface of the support frame 34, a first spring 35 is provided inside the sleeve 24, and a T-shaped rod 37 is slidably installed inside the sleeve 24 and at the lower end of the first spring 35, and rollers 36 are rotatably installed on both sides of the end of the T-shaped rod 37 away from the sleeve 24; like Figure 6 , Figure 7 and Figure 8 As shown, the hydraulic cylinder 22 can cause the support frame 34 to move to one end, whereby the sleeve 24 and the T-bar 37 at the lower end will be elastically pressed by the internal first spring 35, causing the roller 36 to roll and press against the top of the pallet 2, which not only allows the support frame 34 to fix the goods, but also allows the roller 36 to be positioned above the pallet 2.

[0025] A connecting rod 31 is fixedly provided on one side of the outer wall of the assembly seat 28, and a slider 29 is fixedly provided on one end of the connecting rod 31 away from the assembly seat 28, and a screw rod 30 is inserted through the internal thread of the slider 29, and the screw rod 30 is rotatably matched with the angle plate 3, and a third motor 21 is fixedly provided on one end of the screw rod 30, and the third motor 21 is fixedly provided inside one side of the angle plate 3 through the housing frame 20 fixedly set on the outside; like Figure 7 As shown, the third motor 21 can drive the screw 30 to rotate, thereby allowing the corresponding slider 29 to slide downward from the upper part of the inside of the corner plate 3, so that the stop block 27 can be close to the lower part of the outer wall of the pallet 2, thereby preventing the pallet 2 from moving during transportation.

[0026] A connecting rod 13 is fixedly provided on the upper end surface of the support rod 25, and the end of the connecting rod 13 away from the support rod 25 is connected to the bag net 9 through an elastic rope 8. Two racks 7 are respectively provided on the upper part of the frame 4, and a second motor 6 is fixedly provided on one of the racks 7. A rotating drum 19 is fixedly provided on the output end of the second motor 6, and 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 stand 17, and the bearing stand 17 is installed on the upper surface of the rack 7 away from the end of the second motor 6. A fixing seat 18 is fixedly provided on the lower end of the traction rope 16, and the lower end of the fixing seat 18 is connected to the middle of the outer surface of the bag net 9. like Figure 1 , Figure 2 and Figure 5 As 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; 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.

[0027] 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.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only the features of the present invention.
