Description

Technical Field

[0001] This utility model relates to the field of forklift technology, and in particular to a load adjustment device suitable for counterbalance forklifts. Background Technology

[0002] Forklifts, as an important piece of logistics equipment, are widely used in modern warehousing and manufacturing. Through automated navigation systems, AGV forklifts can efficiently complete material handling tasks, significantly improving production efficiency and reducing labor costs. With the development of smart factories, AGV forklifts have become an indispensable part due to their flexibility, precision, and reliability, especially demonstrating excellent performance in cargo loading and unloading scenarios, greatly promoting the modernization of the logistics industry.

[0003] Currently, during forklift loading and unloading, cargo tipping is a common safety hazard and efficiency bottleneck. Tilting cargo may directly injure operators, colleagues, or passersby, especially when stacking at heights (such as working on the upper shelves), where the impact force of falling cargo is extremely large, which may lead to fractures, contusions, or even more serious injuries. To address this, we provide a load adjustment device suitable for counterbalance forklifts. Utility Model Content

[0017] This application provides a load adjustment device suitable for counterbalance forklifts. By incorporating a lifting assembly and a weight monitoring assembly, a drive motor drives two threaded rods to rotate synchronously via a sprocket assembly. A moving plate moves up and down under the influence of the threaded rods and a rectangular plate, adjusting the height of the base plate. Goods can be stacked on top of the placement plate using the forklift body. A force sensor monitors the weight of the goods in real time to prevent overloading. A sliding rod inside the mounting block restricts the position of the placement plate. A clamping assembly ensures that as the lifting assembly raises the goods, both sides of the goods are pressed against the clamping plate. Because the clamping plate is trapezoidal, the clamping force gradually increases under the restoring force of the spring as the goods rise, ensuring a smooth ascent and preventing detachment. A guide rod restricts the position of the clamping plate. Example 1

[0018] The technical solution in this application aims to effectively address the common safety hazard and efficiency bottleneck of goods tipping over during forklift loading and unloading. Tipping over can directly injure operators, colleagues, or passersby, especially when stacking goods at heights (such as on upper shelves), where the impact force of falling goods is extremely high, potentially leading to fractures, contusions, or even more serious injuries. The overall approach is as follows: like Figures 1 to 4 In view of the problems existing in the prior art, this utility model provides a load adjustment device suitable for counterbalance forklifts, including a forklift body 1, a lifting assembly 2 installed on one side of the forklift body 1, clamping assemblies 4 for limiting the goods installed on both sides of the lifting assembly 2, and a weight monitoring assembly 3 for monitoring the goods installed at the bottom of the lifting assembly 2.

[0019] Specifically, the lifting assembly 2 includes a rectangular plate 21. There are two rectangular plates 21. A drive motor 22 is installed on the top of one of the rectangular plates 21. A sprocket assembly 23 is fixedly connected to the output end of the drive motor 22. A threaded rod 24 is fixedly connected to the bottom of the sprocket assembly 23. A movable plate 25 is threadedly connected to the outside of the threaded rod 24. A base plate 26 is fixedly connected to the lower side of one side of the movable plate 25. The two ends of the threaded rod 24 are rotatably connected to the rectangular plate 21 through bearings.

[0020] By adopting the above technical solution, the height of the base plate 26 is adjusted by the lifting assembly 2. Specifically, the drive motor 22 drives the two threaded rods 24 to rotate synchronously through the sprocket assembly 23, and the moving plate 25 moves up and down under the drive of the threaded rods 24 and the rectangular plate 21, thereby realizing the adjustment of the height of the base plate 26.

[0021] Specifically, the weight monitoring component 3 includes a placement plate 31, which is located above the base plate 26. Mounting blocks 34 are fixedly connected to the four bottom corners of the base plate 26, and mounting blocks 34 are fixedly connected to the upper surface of the base plate 26.

[0022] By adopting the above technical solution, the forklift body 1 can stack goods on top of the placement plate 31, the force sensor 32 can monitor the weight of the goods in real time to avoid overloading, and the slide bar 33 can restrict the position of the placement plate 31 by sliding inside the mounting block 34. Example 2

[0023] like Figures 1 to 4 The clamping assembly 4 includes a mounting bracket 41. The mounting bracket 41 is fixedly mounted on one side of the rectangular plate 21 and a pressing plate 45 is provided thereon. A guide rod 42 that is slidably engaged with the mounting bracket 41 is fixedly connected to one side of the pressing plate 45. A connecting plate 44 is fixedly connected to one side of the guide rod 42. A restoring spring 43 is fixedly connected between the connecting plate 44 and the mounting bracket 41. The pressing plate 45 is trapezoidal in shape, and the restoring spring 43 is arranged around the outside of the guide rod 42.

[0024] By adopting the above technical solution, while the lifting component 2 lifts the goods, the two sides of the goods will be in close contact with the squeezing plate 45. Since the squeezing plate 45 is trapezoidal, when the goods are lifted, the squeezing plate 45 will gradually increase the clamping force on the goods under the action of the restoring force of the restoring spring 43, so that the goods can be lifted smoothly and avoid falling off. The guide rod 42 can restrict the position of the squeezing plate 45.

[0025] Working principle: During use, the height of the base plate 26 is adjusted by the lifting assembly 2. Specifically, the drive motor 22 drives two threaded rods 24 to rotate synchronously through the sprocket assembly 23. The moving plate 25 moves up and down under the drive of the threaded rods 24 and the rectangular plate 21, thereby adjusting the height of the base plate 26. The forklift body 1 can stack goods on top of the placement plate 31. The force sensor 32 can monitor the weight of the goods in real time to prevent overloading. The sliding rod 33 slides inside the mounting block 34 to restrict the position of the placement plate 31. At the same time, as the lifting assembly 2 lifts the goods, the two sides of the goods will be in close contact with the extrusion plate 45. Since the extrusion plate 45 is trapezoidal, when the goods rise, the extrusion plate 45 will gradually increase the clamping force on the goods under the action of the restoring force of the restoring spring 43, so that the goods can rise smoothly and avoid falling off. The guide rod 42 can restrict the position of the extrusion plate 45.

[0026] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
