[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 As shown, a working platform includes two ladders 1 positioned one in front of the other. These ladders can be equipped with or without casters. The two ladders 1 face each other, and a connecting bridge 3 is provided between their footboards 4. The connecting bridge 3 is a rectangular plate structure with a length less than the height of the ladder 1. The width of the connecting bridge 3 corresponds to the width of the footboards 4, meaning that the left and right edges of the connecting bridge 3 (the two long edges of the connecting bridge) are flush with the left and right edges of the footboards 4. The upper surface of the connecting bridge 3 is flush with the footboards 4 of the two ladders 1. During operation, workers stand on the connecting bridge 3 to move goods. The range of goods movement is the distance between the two ladders. Compared to the working range of a single ladder, this invention increases the working range of personnel and solves the problems of inconvenience and low efficiency caused by the frequent movement of the ladder and the need for workers to repeatedly climb up and down the ladder to move goods when using a single ladder.

[0026] In this utility model, the connection structure between the connecting bridge 3 and the two ladders 1 is as follows: the front end of the connecting bridge 3 is rotatably installed on the front ladder 1 via the first rotating shaft 8, and the rear end of the connecting bridge 3 is detachably installed on the rear ladder 1.

[0027] The structure of the connecting bridge 3 is as follows Figure 2 As shown, the front and rear bottoms of the connecting bridge 3 are respectively provided with fixing blocks 9. The fixing blocks 9 are preferably strip-shaped block structures arranged along the width direction of the connecting bridge 3. The length of the fixing blocks 9 is less than the width of the connecting bridge 3. The top surface of the fixing blocks 9 is a planar structure and is welded to the bottom surface of the connecting bridge 3. The bottom surface of the fixing blocks 9 is an arc surface.

[0028] Two connecting blocks 10 are respectively installed on the upper part of the two ladders 1 facing each other. The connecting blocks 10 are located below the step 4. The distance between the two connecting blocks 10 on each ladder 1 is greater than the length of the fixing block 9. The fixing block 9 at the front end of the bridge 3 is rotatably connected between the two connecting blocks 10 on the front ladder 1 through the first rotating shaft 8. The fixing block 9 at the rear end of the bridge 3 is located between the two connecting blocks 10 on the rear ladder 1 and is fixed by the pin 6 and the two connecting blocks 10 on the rear ladder 1.

[0029] The connecting bridge 3 and the two ladders 1 are connected by the above-described structure, which facilitates the disassembly of the two ladders 1. After disassembly, the connecting bridge 3 can rotate downwards by 90° around the first pivot 8, as shown below. Figure 3 As shown. When not in use, the two ladders of the aerial work platform can be disassembled and stored separately, reducing the platform's size and making it easier to store.

[0030] In this utility model, the pin 6 structure is as follows: Figure 4As shown, the pin 6 includes a light rod part 61, a threaded rod part 62 and a holding part 63 arranged in sequence, the holding part 63 can be a hand wheel or a nut structure to facilitate personnel to grasp and rotate the pin. The connecting block 10 of the rear ladder 1 is provided with a threaded hole corresponding to the threaded rod part 62, the rear end fixed block 9 of the connecting bridge 3 is provided with a insertion hole 91 corresponding to the light rod part 61, the threaded rod part 62 of the pin 6 is screwed with the threaded hole of the connecting block 10, and the light rod part 61 is inserted into the insertion hole of the fixed block 9 to support the connecting bridge 3.

[0031] In the utility model, one guardrail 2 is arranged on the left and right sides of the connecting bridge 3 respectively, each guardrail 2 is rotatably installed on the outer side of the rear ladder 1 through a second rotating shaft 7 at the upper position of the rear end, and the front end of the guardrail 2 is fixedly connected with the front ladder 1 through a bolt 5. The rear ladder 1 is provided with a threaded hole 101 corresponding to the bolt 5 at the position behind the second rotating shaft 7, the threaded hole 101 and the second rotating shaft 7 are located at the same horizontal height, the rear end of the guardrail 2 is provided with a through hole corresponding to the bolt 5 at the lower position, the distance from the through hole to the second rotating shaft 7 is the same as the distance from the threaded hole 101 to the second rotating shaft 7. When the working platform is in a non-working state, the two ladders are disassembled, the guardrail 2 is disassembled from the front ladder 1, and is rotated downward by 90° around the second rotating shaft 7, and is assembled with the threaded hole 101 through the bolt 5, so that the guardrail 2 is fixed on the rear ladder 1, as shown in the figure. Figure 5 The guardrail 2 improves the working safety of the workers on the connecting bridge 3, and the connecting structure of the guardrail 2 and the rear ladder 1 makes the guardrail 2 and the rear ladder 1 form a whole, so that the guardrail 2 is convenient to save.

[0032] The above only describes the preferred embodiments of the utility model, and does not limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
