[0029] At the construction site, trucks carrying raw materials are often quite tall. After the trucks arrive at the construction site, it is necessary to first roughly count the raw materials, and then climb into the cargo bed of the truck to hang the lifting equipment on the raw materials to gradually unload them.

[0030] Among related technologies, existing climbing ladders have low safety performance, are difficult to use in coordination with vehicles for rapid climbing, and are not easy to carry in vehicles.

[0031] Regarding the problems in related technologies, such as Figures 1-2As shown, this embodiment provides a ladder device for climbing unloading vehicles, including a main ladder frame 10. Handrails 40 are provided on both sides of the main ladder frame 10. A hook portion 41 is provided on the handrail 40 at the top of the main ladder frame 10, which is used to engage with the vehicle's side panels. The main ladder frame 10 includes a fixed step portion 11 and a rotating step portion 12. The fixed step portion 11 and the rotating step portion 12 are connected by a folding connecting assembly 20, allowing the rotating step portion 12 to rotate relative to the fixed step portion 11. Side panels are provided on both sides of the cargo bed of a truck to create cargo space for placing goods. However, due to the height of the side panels, it is usually difficult to count raw materials on the ground and to climb the ladder. In this embodiment, by setting a hook part 41 on the handrail 40, the hook can be hung in conjunction with the baffle, which facilitates the erection of the main ladder frame 10, realizes the rapid construction of the climbing passage, improves the erection efficiency, and enables workers to climb quickly. Furthermore, by setting the folding connecting component 20, the entire ladder can be folded, which is convenient for folding and storage, and also allows for quick climbing and viewing when folded at a certain angle, realizing the multi-functional configuration of the ladder.

[0032] Specifically, the main ladder frame 10 is a conventional climbing ladder structure, and the handrails 40 are connected to both sides of the main ladder frame 10, thus providing a protective function. By setting a hook part 41 at the top of the handrail 40, it can be hung on the truck baffle to form a climbing channel for rapid climbing.

[0033] In a specific configuration, the handrail 40 is fixedly connected to the main ladder frame 10. This fixed connection enhances the stability and strength of the handrail 40. Alternatively, the handrail 40 can be detachably connected. For example, it can be connected to the main ladder frame 10 via pins or bolts, allowing for a detachable design. This detachable connection facilitates overall folding and makes it easy to carry in the vehicle.

[0034] In some embodiments, the main ladder frame 10 includes an aluminum alloy main frame, with multiple ladder blocks fixedly connected between the aluminum alloy main frames. The aluminum alloy main frame design makes the overall structure lightweight and easy to transport.

[0035] Specifically, the aluminum alloy main frame includes two aluminum alloy columns arranged opposite each other, and ladder blocks are connected between the two aluminum alloy columns to form the ladder structure of the main frame 10. In the specific connection, the ladder blocks are connected to the two aluminum alloy columns by welding to improve the structural strength of the main frame 10.

[0036] In the specific setup, each step block is equipped with an anti-slip rubber sleeve 15. The anti-slip rubber sleeve 15 can improve the safety of climbing and prevent slipping when going up or down the steps.

[0037] Specifically, the anti-slip rubber sleeve 15 can be a polyurethane anti-slip sleeve. The anti-slip rubber sleeve 15 is installed on the step block by bolts or adhesive to provide greater friction when going up and down the steps and prevent slipping.

[0038] In some embodiments, anti-slip pads 13 are provided at the bottom of the main ladder frame 10. When climbing and when using the ladder device to count materials, the bottom of the main ladder frame 10 is in contact with the ground. In this embodiment, by providing anti-slip pads 13 at the bottom of the main ladder frame 10, the ladder can be effectively prevented from sliding, thus improving its stability.

[0039] Specifically, such as Figure 1 Figure 5 As shown, anti-slip pads 13 are provided at the bottom of both aluminum alloy columns to prevent slipping during the process of going up and down the steps.

[0040] In some embodiments, such as Figure 3 , Figure 4 As shown, the folding connection assembly 20 includes a fixed part 21 connected to the fixed step part 11, a rotating part 22 connected to the rotating step part 12, and a locking connector 30. The fixed part 21 has a rotating shaft 23, and the rotating part 22 has a corresponding shaft hole. The rotating shaft 23 is disposed within the shaft hole, allowing the rotating part 22 to rotate around the fixed part 21. The locking connector 30 is disposed on the rotating part 22 and is used to lock the rotating part 22 in place. During the rotation of the rotating step, it forms an angle with the fixed step. The locking connector 30 locks the rotating step part 12, maintaining the angled state, thus enriching the functionality of the climbing device and making the overall structure more stable.

[0041] Specifically, in, such as Figure 3 As shown, a slot 211 is provided on the fixed part 21, and the rotating shaft 23 is provided in the slot 211. A protrusion is provided on the rotating part 22, and a shaft hole is provided on the protrusion. The rotating shaft 23 is located in the shaft hole, so that the rotating part 22 can rotate around the rotating shaft 23. The locking connector 30 is fixedly connected to the rotating part 22 and can restrict the rotation of the rotating part 22.

[0042] In some embodiments, the locking connector 30 includes a connecting plate 31 and a pin 32. The connecting plate 31 is fixedly connected to the rotating part 22. A fixing hole 311 is provided on the connecting plate 31, and a corresponding position hole 212 is provided on the fixing part 21. The pin 32 passes through the fixing hole 311 and is inserted into the position hole 212. The connection by the pin 32 enables the rotating step part 12 to maintain a stable state after rotating to a designated position, which is beneficial for load bearing and provides a stable and safe passage.

[0043] Specifically, multiple position holes 212 are provided on the fixing part 21 according to the requirements. When the fixing hole 311 rotates with the rotating part 22, it can correspond to the fixing hole 311. That is, the center of the fixing hole 311 and the position hole 212 are on the same straight line. At this time, the connecting plate 31 can be positioned by inserting the pin 32, thereby preventing the rotating part 22 from rotating and maintaining the stability of the rotating part 22 in a specific position.

[0044] In some embodiments, such as Figure 2 , Figure 5 As shown, the position holes 212 include a first unfolded position hole 212 and a second unfolded position hole 212. When the fixing hole 311 corresponds to the first unfolded position hole 212, the included angle between the rotating part 22 and the fixing part 21 is an acute angle. When the fixing hole 311 corresponds to the second unfolded position, the included angle between the rotating part 22 and the fixing part 21 is 180°. The arrangement of the two position holes 212 enables the climbing device to have two modes: a folding climbing mode and an unfolded climbing mode. Switching between the two modes enriches the functionality of the climbing device.

[0045] It is understandable that, in the folding and climbing mode, there is an acute angle between the rotating part 22 and the fixed part 21, such as... Figure 5 As shown, this method allows workers to stand and quickly count the raw materials. After sorting the materials, they need to climb into the cargo bed of the truck. By rotating it to the second unfolding position hole 212, the rotating part 22 and the fixed part 21 are aligned, allowing it to extend to the truck baffle. The hook part 41 cooperates with the truck baffle to form a passageway for workers to move up and down.

[0046] Specifically, when the fixing hole 311 corresponds to the first unfolded position hole 212, the included angle between the rotating part 22 and the fixing part 21 is 30°-45°. At this angle, workers can climb up the steps along one side to count materials or assist in lifting operations. When the truck's side panel is too high, the rotating part 22 needs to be rotated to the second unfolded position. At this time, the rotating part 22 is in the extension direction of the fixing part 21, and can then be hung on the truck's side panel to form a passage for workers to move up and down.

[0047] In some specific embodiments, both the fixing hole 311 and the position hole 212 are hexagonal holes, and the corresponding pin 32 is a hexagonal prism pin 32. By limiting the hexagonal shape, the axial rotation of the pin 32 can be restricted after it is inserted, thereby making the overall structure more stable.

[0048] Specifically, when the fixing hole 311 corresponds to the position hole 212, the connecting plate 31 connects the fixing part 21 and the rotating part 22 by inserting a hexagonal hole, which can restrict the rotation of the rotating part 22 and thus improve the stability of the overall structure.

[0049] In some specific embodiments, such as Figure 4 As shown, two hexagonal fixing holes 311 are provided on the connecting plate 31. The two hexagonal fixing holes 311 can correspond to the first unfolded position hole 212 and the second unfolded position hole 212, thereby realizing the corresponding setting of the pin 32.

[0050] In a specific configuration, the hook portion 41 is fitted with an anti-slip sleeve. The anti-slip sleeve ensures good stability of the climbing device in both modes, preventing slippage and thus improving the safety of the passageway.

[0051] It is understandable that, such as Figure 5 As shown, in the folding climbing mode, the anti-slip sleeve can contact the ground, thereby achieving anti-slip contact for the climbing device and preventing the climbing device from slipping during the up and down operation.

[0052] Through the above description of the embodiments, those skilled in the art can clearly understand that each embodiment, through the arrangement of the main ladder frame 10 and the folding connecting component 20, enables convenient inventory of raw materials during unloading and quick vehicle climbing. The overall structure is simple, and the hook part 41 facilitates quick mounting for easy climbing. Furthermore, the folding connecting component 20 enriches the function of the ladder device, enabling it to climb and ascend when inventorying raw materials and climbing trucks, thus improving its applicability.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
