Description

Technical Field

[0001] This utility model belongs to the technical field of pallet bases, and more specifically, it relates to a base for preventing goods from tipping over. Background Technology

[0002] Pallets, as essential loading, unloading, storage, and transportation equipment in modern logistics operations, can play a significant role when used in conjunction with forklifts. With the increasing maturity of various transportation modes such as road, rail, water, and air transport, the application of logistics pallets is becoming more and more widespread, becoming a multimodal transport method on par with container transport and piggyback transport.

[0003] Based on the above, the following problems were found: When using the existing pallet base, workers stack goods on the logistics pallet and then lift it with a forklift for transportation and movement. When the forklift moves slightly violently, the pallet base will shake, and the goods on the pallet base may slip off the pallet, causing damage to the goods. By adding a drive device and a limit device to the base to limit the goods, it is necessary to repeatedly limit and release the limit during transportation, which is inconvenient to use.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a base that prevents goods from tipping over, in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a base to prevent goods from tipping over, so as to solve the problem that goods on the pallet base may slip off the pallet during current transportation.

[0006] This utility model provides a base to prevent goods from tipping over, achieved through the following specific technical means:

[0007] A base for preventing cargo from tipping over includes a base body. Pads are fixed to both sides of the top of the base body. A driven gear is rotatably connected to the center of the top of the base body. A drive rack is slidably connected to one side of each of the two pads. Limit rods are fixed to opposite ends of each of the two drive racks. Nylon ropes are fixed to opposite ends of each of the two drive racks. Telescopic rods are fixed to the bottom of both ends of each pad. Sleeves are movably sleeved on the outer walls of each of the two telescopic rods. Counterweights are fixed to the bottom of each sleeve. Second connecting rods are fixed to the top of one side of each sleeve. One end of each of the two second connecting rods is fixed to one of the two nylon ropes.

[0008] Furthermore, the two active racks are arranged with their teeth facing each other, and both active racks mesh with the driven gear.

[0009] Furthermore, the thickness of the active rack is equal to the thickness of the driven gear and less than the thickness of the pad, and the limiting rod is located in the middle of the two pads, and the limiting rod is slidably connected to the two pads.

[0010] Furthermore, support blocks are fixed on both sides of the middle of the two pads at the top of the base body, and a return spring is fixed on the opposite end of the two support blocks. One end of the two return springs is fixed to the two limit rods respectively.

[0011] Furthermore, a first connecting rod is fixed to the top of one side of each of the two telescopic rods, and a fixed pulley is rotatably connected to the side of each of the two first connecting rods near the nylon rope. The two nylon ropes are respectively wrapped around the outer wall of the two fixed pulleys.

[0012] Furthermore, rubber pads are fixed to the opposite sides of both limiting rods.

[0013] Furthermore, a partition block is fixed on both sides of the bottom of the base, and an insertion hole is provided through the middle of one end of the partition block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, the counterweight block remains in place due to gravity as the base moves upward. The two ends of the telescopic rod and the sleeve rod extend, driving the fixed pulley to move upward and stretching the nylon rope. The other end of the nylon rope pulls the active rack. When one of the active racks moves, it drives the driven gear to rotate, which in turn drives the other driven rack to move in the opposite direction at an equal distance. This causes the two limiting rods to move towards the center at the same time, clamping the goods, thereby achieving the effect of quickly limiting the goods above the base.

[0016] 2. In this utility model, after the goods are transported to the designated location, the forklift's forks are controlled to unload the base onto the ground, so that the base falls on top of the counterweight. At this time, the limit rod is not affected by external force, and the two return springs support the two limit rods respectively. The two limit rods return to their original positions at both ends of the base body, thereby achieving the effect of automatic limit and automatic release of limit, making it more convenient to use.

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides a base for preventing cargo from tipping over, including a base body 1. Pads 2 are fixed to both sides of the top of the base body 1. A driven gear 4 is rotatably connected to the middle of the top of the base body 1. A drive rack 5 is slidably connected to one side of each of the two pads 2. Limiting rods 6 are fixed to opposite ends of each of the two drive racks 5. Nylon ropes 9 are fixed to opposite ends of each of the two drive racks 5. Telescopic rods 10 are fixed to the bottom of both ends of the pads 2. Sleeves 13 are movably sleeved on the outer walls of each of the two telescopic rods 10. Counterweights 15 are fixed to the bottom of each of the two sleeves 13. Second connecting rods 14 are fixed to the top of one side of the outer walls of each of the two sleeves 13. The two second connecting rods 14 are fixed to one end of each of the two nylon ropes 9.

[0028] The two active racks 5 are arranged with their teeth facing each other, and both active racks 5 mesh with the driven gear 4, so that when one of the active racks 5 moves, it can drive the driven gear 4 to rotate, thereby driving the other driven rack 5 to move in the opposite direction at an equal distance.

[0029] The thickness of the active rack 5 is equal to the thickness of the driven gear 4 and less than the thickness of the pad 2. The limiting rod 6 is located in the middle of the two pads 2 and is slidably connected to the two pads 2, so that when the goods are placed on the top of the pads 2, the bottom of the goods will not touch the active rack 5 and the driven gear 4, and the active rack 5 will not move and the driven gear 4 will not rotate.

[0030] Among them, support blocks 8 are fixed on both sides of the middle of the two pads 2 at the top of the base body 1. Reset springs 7 are fixed on opposite ends of the two support blocks 8. One end of the two reset springs 7 is fixed to the two limit rods 6 respectively. The two limit rods 6 are supported by the two reset springs 7 respectively, so that when the limit rods 6 are not affected by external force, the two limit rods 6 can stay at both ends of the base body 1.

[0031] Each of the two telescopic rods 10 has a first connecting rod 11 fixed to one side of its top. Each of the two first connecting rods 11 is rotatably connected to a fixed pulley 12 near the side of the nylon rope 9. The two nylon ropes 9 are respectively wrapped around the outer wall of the two fixed pulleys 12. The base body 1 of the limiting rod 6 is connected through the nylon ropes 9. At the same time, the fixed pulleys 12 can support the nylon ropes 9, so that the nylon ropes 9 can move better.

[0032] Among them, rubber pads 61 are fixed on opposite sides of the two limiting rods 6. The rubber pads 61 make the friction between the limiting rods 6 and the goods on the top of the pad block 2 greater.

[0033] The base body 1 has two partition blocks 3 fixed on the middle of the bottom. One end of the partition block 3 has a through hole 31. The partition block 3 makes a certain gap between the base 1 and the counterweight 15 when they are normally placed, so that the forklift fork can be inserted into the bottom of the base 1.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In this invention, goods are first stacked on top of pad 2. The thickness of the driving rack 5 is equal to the thickness of the driven gear 4 and less than the thickness of pad 2, ensuring that the bottom of the goods does not touch the driving rack 5 and driven gear 4 when placed on top of pad 2, preventing the driving rack 5 from moving and the driven gear 4 from rotating. The partition block 3 ensures a certain gap between the base 1 and the counterweight 15 when normally placed. Then, the forklift forks are inserted into the bottom of the base 1, and the forks are lifted upwards. The counterweight 15 remains in place due to gravity. At this time, the ends of the telescopic rod 10 and the sleeve rod 13 extend, causing the fixed pulley 12 to move upwards, while simultaneously stretching the nylon rope 9. When one of the active racks 5 moves, it drives the driven gear 4 to rotate, which in turn drives the other driven rack 5 to move in the opposite direction at an equal distance. This causes the two limit rods 6 to move towards the center at the same time, clamping the goods. The rubber pads 61 increase the friction between the limit rods 6 and the goods on the top of the pad block 2. When the limit rods 6 touch the goods, the nylon rope 9 stops pulling. At this time, the counterweight block 15 moves upward together. After the goods are transported to the designated position, the forklift forks are controlled to unload the base 1 onto the ground, so that the base 1 rests on the top of the counterweight block 15. At this time, the limit rods 6 are not affected by external forces. The two return springs 7 support the two limit rods 6 respectively, and the two limit rods 6 return to their original positions at both ends of the base body 1.
