[0019] like Figure 1 and Figure 2 As shown, the utility model provides an aerial work platform device, including an inclined ladder 1 and a vertical ladder 2 fixed to the top of a wall, the inclined ladder 1 is connected to the top of the vertical ladder 2, and both the inclined ladder 1 and the vertical ladder 2 include support rods 21 vertically connected to the wall on both sides and a climbing rod 23 connected between the two support rods 21. A work platform 3 is slidably connected to the vertical ladder 2, and connecting structures for connecting the work platform 3 are equidistantly arranged on the vertical ladder 2. A detachable guardrail 4 is connected to the outer periphery of the top of the work platform 3.

[0020] The support rods 21 in the inclined ladder 1 and the vertical ladder 2 are installed using expansion bolts or pre-buried forms, so that the support rods 21 are vertically fixed on the wall. The staff climbs the ladder rod 23 between the two support rods 21. The staff enters the vertical ladder 2 through the inclined ladder 1 and finally enters the working platform 3 to carry out wall repair work on the working platform 3.

[0021] like Figure 2 As shown, to ensure the stability of support rod 21, a support plate 22 is connected to the fixed end of the support rod 21, and the support plate 22 is attached to the wall. The end of the support rod 21 is inserted into the wall, and the support plate 22 is welded to the support rod 21. The support plate 22 has through holes for installing expansion bolts.

[0022] like Figure 2 As shown, the vertical ladder 2 includes an axially arranged guide rod 24 connected to the support rod 21. The work platform 3 is fixedly provided with an arc-shaped connecting ear 32 with a central angle greater than 180°. The inner wall of the connecting ear 32 abuts against the guide rod 24. The support rod 21 is connected to one side of the guide rod 24, and the other three side surfaces of the guide rod 24 contact the inner wall of the connecting ear 32. This ensures that the connecting ear 32 abuts against the guide rod 24, and that the work platform 3 does not interfere with the structure within the vertical ladder 2 when it moves axially along the guide rod 24 via the connecting ear 32.

[0023] like Figure 2 As shown, to further improve the stability of the movement of the connecting ear 32, guide grooves 26 are axially defined on both sides of the guide rod 24. Adaptive protrusions are provided on the inner side of the connecting ear 32, and the adaptive protrusions are located in the guide grooves 26. The connecting ear 32 can also be fastened to the guide rod 24 by engaging the two adaptive protrusions with the guide grooves 26.

[0024] like Figure 2As shown, to reduce the weight of the work platform 3 and, in turn, the load on the connecting structure, the work platform 3 comprises a rectangular connecting frame 31, a grating plate 33 secured within the connecting frame 31, and a mounting plate 34 secured to the outside of the connecting frame 31. The bottom end of the guardrail 4 is mounted on the mounting plate 34. The sufficiently strong grating plate 33 provides support for workers while also reducing the weight of the work platform 3. The bottom end of the guardrail 4 is inserted into the equally spaced connection holes on the mounting plate 34. Bolts are then screwed into the mounting plate 34 from one side and connected to the threaded holes at the bottom end of the guardrail 4. The guide rod 24 of the vertical ladder 2 has an annular stopper protrusion at the bottom end, so the connecting lug 32 is pre-installed. The removable guardrail 4 facilitates assembly of the work platform assembly. During the assembly process, assembly of the work platform 3 takes priority. After the work platform 3 is connected to the connecting lug 32, the connecting structure is complete, securing the work platform 3. The guardrail 4 is then lowered with ropes and finally mounted on the work platform 3.

[0025] like Figure 2 As shown, to improve the stability of the work platform 3, a diagonal brace 35 is connected to the bottom of the end of the connecting frame 31 away from the guide rod 24. The movable end of the diagonal brace 35 is connected to the connecting lug 32. The connecting structure serves as the support structure for one end of the work platform 3, while the diagonal brace 35 and connecting lug 32 serve as the support structure for the other end of the work platform 3.

[0026] like Figure 2 The connection structure includes a connecting plate 25 fixedly connected between the two support rods 21. A connecting platform 36 is fixedly connected to the top of the work platform 3. Connecting holes are provided between the connecting platform 36 and the connecting plate 25, and triangular reinforcing ribs are connected between the ends of the connecting platform 36 and the work platform 3. By connecting the connecting platform 36 and the connecting plate 25 with bolts, one end of the work platform 3 can be fixed to the vertical ladder 2.
