[0016] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0017] like Figure 1-5 As shown, a foldable operating platform device includes a platform 1, a ladder base 4, and a folding ladder. The top of the folding ladder is connected to the platform 1 via the ladder base 4. A clamping rod 2 is provided at the bottom of the platform 1 away from the folding ladder. The clamping rod 2 is connected to a clamping nut 3 on the inner side of the platform 1 via a screw 7. When in use, the platform 1 is clamped to a flatbed cart by a positioning plate at the front end and the clamping rod 2. Specifically, the bottom plate of the ladder base 4 is fixed to the top surface of the platform 1 by multiple base bolts 5. In one embodiment, each ladder base has four base bolts 5.

[0018] Specifically, the folding ladder includes a first ladder 6 and a second ladder 9. Both the first ladder 6 and the second ladder 9 include two side plates and multiple ladder treads 8 connected in the middle. The top of the second ladder 9 is hinged to the ladder base 4 via an upper mounting plate 901, and the bottom of the second ladder 9 is hinged to the upper movable connecting plate 601 of the first ladder 6 via a lower movable connecting plate 902. In one specific embodiment, both the first ladder 6 and the second ladder 9 are designed with a double ladder tread 8 structure. Their overall lengths are roughly equal, but the width of the first ladder 6 is slightly smaller than that of the second ladder 9, facilitating their insertion and positioning when hinged.

[0019] Specifically, the upper mounting plate 901 and the lower movable connecting plate 902 are fixedly connected to the outer sides of the two side plates of the second ladder 9 by hinge bolts 10 and self-locking nuts 11, and the upper movable connecting plate 601 is fixedly connected to the outer sides of the two side plates of the first ladder 6 by hinge bolts 10 and self-locking nuts 11.

[0020] Specifically, the upper mounting plate 901 is designed in a 7-shape, and its top end is hinged to the top of the ladder base 4 via hinge bolts 10 and self-locking nuts 11. The hinge end of the upper movable connecting plate 601 is embedded in the lower movable connecting plate 902 and is rotatably connected together via a set of hinge bolts 10 and self-locking nuts 11. The hinge bolts 10 connecting the upper mounting plate 901 and the ladder base 4 form the upper hinge axis, enabling the second ladder 9 (synchronously driving the first ladder 6) to flip, fold, or open towards the platform 1. The hinge bolts 10 connecting the upper movable connecting plate 601 and the lower movable connecting plate 902 form the middle hinge axis of the ladder, enabling the first ladder 6 to flip, fold, or open towards the second ladder 9.

[0021] Specifically, the foot surface of the ladder step 8 is provided with multiple anti-slip pads, which are flat rubber pads or multiple cylindrical or annular rubber pads positioned and connected to the foot surface; the top surface of the platform 1 is provided with anti-slip patterns, which are water ripple patterns, X, V or Y patterns.

[0022] The screw 7 includes a vertical screw body and a movable wrench at the bottom, the movable wrench being connected through the bottom of the screw body; the top of the screw body is connected through the clamping rod 2 and then screwed tightly onto the clamping nut 3, the clamping nut 3 being welded into the platform 1.

[0023] Specifically, the system consists of ladder 1 (6), ladder 2 (9) (including footboard), platform 1, clamping rod 2, ladder base 4, and other components. It can preferably be made of materials such as aluminum alloy, galvanized steel pipe, or carbon steel, which have anti-slip, load-bearing, and corrosion-resistant properties, ensuring the connection strength of the device and extending its service life.

[0024] The usage process of this utility model is as follows: First, it is connected to the flatbed truck. The front end of the platform 1 is flush with and abuts against the bottom plate of the flatbed truck. The clamping rod 2 is clamped and connected to the vertical bracket on the side wall of the flatbed truck. Rotate the movable wrench of the screw 7 to drive the screw 7 to tighten onto the clamping nut 3, and simultaneously drive the clamping rod 2 to move upward. Finally, it is clamped and positioned on the flatbed truck by the positioning plate at the front end of the platform 1 and the clamping rod. Next, rotate outwards to open ladder 6, then continue rotating outwards to open ladder 9, until fully extended as shown. Figure 1 As shown; specifically, ladder 2 9 (synchronously driving ladder 1 6) flips open around the upper hinge axis away from platform 1. The hinge bolt 10 used to connect the upper movable connecting plate 601 and the lower movable connecting plate 902 forms the hinge axis in the middle of the ladder, so that ladder 1 6 flips open downward around the middle hinge axis, away from ladder 2 9 and finally lies on an inclined straight line.

[0025] like Figure 6As shown, when not in use, first rotate ladder 6 upwards to bring it close to ladder 9 and then fold them together. Continue to fold upwards, and ladder 9 will simultaneously drive ladder 6 to the top of platform 1. After the folding operation is completed, rotate the adjustable wrench in the opposite direction to move the screw 7 away from the clamping nut 3, and finally move the clamping rod 2 down in sync, eliminating the clamping force and allowing the entire device to be disassembled smoothly.

[0026] Clamping and disassembly can be performed directly using the adjustable wrench at the bottom of screw 7, requiring no additional work and making operation more convenient and faster. Furthermore, the entire device uses a purely mechanical connection method, eliminating the need for lifting ropes and hydraulic components, effectively reducing manufacturing costs.
