Description

Technical Field

[0001] This utility model relates to the field of wheel shock absorption technology, specifically to a high-load-bearing shock-absorbing wheel for cargo trucks. Background Technology

[0002] Against the backdrop of the rapid development of the modern logistics and warehousing industry, warehouse trucks, as core equipment for material transfer and cargo loading and unloading, have expanded their application scenarios from traditional flat warehouses to diverse environments such as automated warehouses, ports and docks, and heavy manufacturing workshops. The load-bearing capacity has increased from hundreds of kilograms per wheel in the early days to several tons or even tens of tons. They often need to operate continuously under conditions of frequent starts and stops and uneven ground (such as forklift tracks and raised areas left after goods fall). At the same time, they need to ensure that the transported goods (such as precision parts, fragile items, and cold chain fresh produce) are not damaged by vibration. This places rigid requirements on the high load-bearing capacity and shock absorption performance of the wheels.

[0003] Existing high-load-bearing shock-absorbing wheels mainly rely on multiple springs for shock absorption. However, this method has a drawback: when the cargo is too light, the shock absorption effect is very small, and it may even cause the cargo to fall off the cargo truck, resulting in damage. When the cargo is too heavy, the springs will be compressed to the bottom, reducing the shock absorption effect. Therefore, a high-load-bearing shock-absorbing wheel for cargo trucks is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a high-load-bearing shock-absorbing wheel for cargo trucks to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a high-load-bearing shock-absorbing wheel for cargo trucks, comprising a rectangular mounting plate. Circular sliding holes are provided at the four corners of the top side of the rectangular mounting plate. Two circular rotating holes are provided on the top side of the rectangular mounting plate, and the two circular rotating holes are positioned far apart from each other. A cylindrical sliding rod is slidably connected within each circular sliding hole. A triangular mounting plate is fixedly connected to the bottom end of the two corresponding cylindrical sliding rods. A shock-absorbing spring is sleeved on the outer side of each cylindrical sliding rod. Two adjusting components are provided on the rectangular mounting plate for adjusting the tension of the two shock-absorbing springs.

[0006] As a further improvement to this technical solution, each of the adjustment components includes a pressing bolt and a metal pressing plate. The pressing bolt is rotatably connected in a circular rotating hole. The metal pressing plate has two limiting holes on its top, and the two limiting holes are set far apart from each other. A pressing threaded hole is provided at the center of the top side of the metal pressing plate. The pressing bolt is threadedly connected in the pressing threaded hole. Rotating the pressing bolt drives the metal pressing plate to move vertically.

[0007] As a further improvement to this technical solution, each of the two triangular mounting plates has a first circular mounting hole on one side, and the two first circular mounting holes are located on the same horizontal line.

[0008] As a further improvement to this technical solution, the same circular rotating shaft is rotatably connected to the two first circular mounting holes, and multiple anti-slip rubber wheels are fixedly sleeved on the outside of the circular rotating shaft, and the multiple anti-slip rubber wheels are arranged in a linear array.

[0009] As a further improvement to this technical solution, a rectangular metal mounting plate is fixedly connected to the center of the top side of the rectangular mounting plate, and a second circular mounting hole is opened at each of the four corners of the top side of the rectangular metal mounting plate. The rectangular metal mounting plate is fixed to the cargo vehicle through multiple second circular mounting holes.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In the high-load-bearing shock-absorbing wheels of cargo trucks, the shock absorption effect is reduced due to excessively heavy or light loads. By using two adjustable components, the shock absorption force of multiple shock-absorbing springs can be adjusted according to the weight of the load. First, by rotating two compression bolts, two metal compression plates are moved vertically. When the load is too heavy, the two metal compression plates move vertically downward, compressing the two shock-absorbing springs. When the load is too light, the two metal compression plates move vertically upward, increasing the shock absorption effect. This solves the problem of poor shock absorption caused by excessively heavy or light loads. Attached Figure Description

[0015] Please see Figures 1-4 As shown, this embodiment provides a high-load-bearing shock-absorbing wheel for a cargo truck, including a rectangular mounting plate 100. Circular sliding holes 200 are provided at the four corners of the top side of the rectangular mounting plate 100. Two circular rotating holes 300 are provided on the top side of the rectangular mounting plate 100, and the two circular rotating holes 300 are arranged far apart from each other. A cylindrical sliding rod 400 is slidably connected in each circular sliding hole 200. A triangular mounting plate 500 is fixedly connected to the bottom end of the two corresponding cylindrical sliding rods 400. A shock-absorbing spring 600 is sleeved on the outside of each cylindrical sliding rod 400. Two adjusting components 700 are provided on the rectangular mounting plate 100, and the adjusting components 700 are used to adjust the tension of the two shock-absorbing springs 600.

[0016] In practical applications, multiple circular sliding holes 200 on the rectangular mounting plate 100 allow multiple cylindrical sliding rods 400 to slide on the rectangular mounting plate 100. The shock-absorbing springs 600 on the outer side of each cylindrical sliding rod 400 provide cushioning for the two triangular mounting plates 500. The two circular rotating holes 300 facilitate the installation and use of the two adjustment components 700. Simultaneously, the two adjustment components 700 can adjust the shock-absorbing effect of the multiple shock-absorbing springs 600, ensuring a suitable shock-absorbing effect based on the weight of the goods.

[0017] Please see Figures 1-3As shown, each adjustment component 700 includes a pressing bolt 701 and a metal pressing plate 702. The pressing bolt 701 is rotatably connected in the circular rotating hole 300. The metal pressing plate 702 has two limiting holes on its top, and the two limiting holes are set far apart from each other. A pressing threaded hole 703 is provided at the center of the top side of the metal pressing plate 702. The pressing bolt 701 is threadedly connected in the pressing threaded hole 703. Rotating the pressing bolt 701 drives the metal pressing plate 702 to move vertically.

[0018] In practical applications, rotating the two compression bolts 701 drives the two metal compression plates 702 to move vertically. When the goods are too heavy, the two metal compression plates 702 move vertically downward to compress the two shock-absorbing springs 600. When the goods are too light, the two metal compression plates 702 move vertically upward to increase the shock absorption effect.

[0019] Please see Figure 1 and Figure 4 As shown, each of the two triangular mounting plates 500 has a first circular mounting hole 800 on one side, and the two first circular mounting holes 800 are located on the same horizontal line. The same circular rotating shaft 900 is rotatably connected inside the two first circular mounting holes 800. Multiple anti-slip rubber wheels 110 are fixedly sleeved on the outside of the circular rotating shaft 900, and the multiple anti-slip rubber wheels 110 are arranged in a linear array. A rectangular metal mounting plate 120 is fixedly connected to the center of the top side of the rectangular mounting plate 100. Second circular mounting holes 130 are opened at the four corners of the top side of the rectangular metal mounting plate 120. The rectangular metal mounting plate 120 is fixed to the cargo truck through the multiple second circular mounting holes 130.

[0020] In practical applications, the two first circular mounting holes 800 on one side of the two triangular mounting plates 500 facilitate the installation of the circular rotating shaft 900. Multiple anti-slip rubber wheels 110 can rotate between the two triangular mounting plates 500 via the circular rotating shaft 900. At the same time, the multiple anti-slip rubber wheels 110 can increase the load-bearing capacity of the cargo truck. The rectangular metal mounting plate 120 and multiple second circular mounting holes 130 facilitate the installation of shock-absorbing wheels.
