Description

Technical Field

[0001] The utility model belongs to the field of building operating platforms, and in particular relates to a ladder climbing device used for a scaffold operating platform. Background Art

[0002] Because the indoor span of large factory halls is large and the floor height is high, workers need to use a large operating platform when performing operations such as plastering and puttying. It is an unsafe operation behavior for operators to climb up and down the operating platform directly every day. Therefore, it is very necessary to study a method that is easy to disassemble, which not only ensures the personal safety of workers, but also provides a more comfortable and fast climbing environment. Utility Model Content

[0003] The utility model aims to provide a ladder device for a light aluminum alloy scaffolding operating platform. The ladder device has the characteristics of convenient disassembly and high climbing safety.

[0004] The utility model can be realized through the following technical solutions:

[0005] A ladder device for a scaffolding operating platform comprises a ladder and a ladder supporting frame.

[0006] The climbing ladder is composed of a plurality of ladder horizontal bars connected at intervals to two ladder vertical bars, and the upper ends of the ladder vertical bars are provided with hook parts.

[0007] The ladder support frame comprises 2 support rods and 1-2 support cross rods; the ends of the support cross rods are welded to the support rods, one end of the ladder support frame is movably connected to the lower half of the ladder, and the other end has a support fork.

[0008] Optimization solution: A grooved mounting seat is fixedly arranged near the lower end of the ladder vertical rod of the ladder, and a mounting axis hole is horizontally opened on the grooved mounting seat. The support rod end of the ladder support frame has a flat joint and a support axis hole. The two flat joints at the ends of the support rod are respectively inserted into the two grooved mounting seats, and bolts are passed through the mounting axis holes of the grooved mounting seats and the support axis holes of the support rods to movably connect the end of the ladder support frame to the ladder.

[0009] Further optimization plan: the supporting fork of the ladder support frame is a claw-type structure, and the end of the supporting rod has a double semi-arc claw, and an arc-shaped rear claw is movably connected between the double semi-arc claws.

[0010] When in use, the hook portion at the upper end of the ladder is hung on the upper crossbar of the scaffolding, and the supporting fork portion of the ladder support frame is hung on the lower crossbar of the scaffolding operating platform. The ladder support frame supports the ladder into an inclined structure, which is convenient for construction workers to enter the operating platform at the top of the scaffolding through the ladder. When not in use, the ladder device is removed from the scaffolding and the ladder support frame is folded to make the supporting fork portion close to the ladder, which is convenient for transportation and storage.

[0011] The utility model has the characteristics of simple structure and convenient use. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural schematic diagram of the utility model.

[0014] The present invention will be further described below with reference to the specific embodiments of the accompanying drawings:

[0015] Example

[0016] refer to Figure 1 and Figure 2 A ladder device for a scaffolding operating platform comprises a ladder and a ladder support frame; the ladder is composed of a plurality of ladder cross bars 12 connected at intervals to two ladder vertical bars 11, the upper ends of the ladder vertical bars 11 have hook portions (13), and the ladder vertical bars 11 of the ladder of this embodiment are fixedly provided with a groove-shaped mounting seat 14 near the lower end side, and the groove-shaped mounting seat 14 is horizontally opened with a mounting shaft hole.

[0017] The ladder support frame includes two support rods 21 and one support cross rod 22. The end of the support cross rod 22 is welded to the support rod 21. One end of the support rod 21 of this embodiment has a support fork, and the other end has a flat joint and a support shaft hole. The flat joints at the ends of the two support rods 21 are respectively inserted into the grooved mounting seats 14 of the two ladders, and bolts pass through the mounting shaft holes of the grooved mounting seats 14 and the support shaft holes of the support rods 21 to movably connect the ends of the ladder support frame to the ladder.

[0018] The supporting fork of the ladder support frame is a claw-shaped structure, and the end of the supporting rod 21 is provided with a double semi-arc claw 23, and an arc-shaped rear claw 24 is axially movably connected between the double semi-arc claws 23.

[0019] When using (such as Figure 2 ), hang the hook part 13 at the upper end of the ladder on the upper crossbar 3 of the scaffold, and hang the supporting fork part of the ladder support frame on the lower crossbar 4 of the scaffold operating platform. The ladder support frame supports the ladder into an inclined structure, which is convenient for construction workers to enter the operating platform at the top of the scaffold through the ladder. When not in use, the ladder device is removed from the scaffold and the ladder support frame is folded to make the supporting fork part close to the ladder, which is convenient for transportation and storage.
