Description

Technical Field

[0001] This utility model relates to the field of high-altitude protection devices, and in particular to a high-altitude platform protection enclosure device. Background Technology

[0002] The erection of aerial work platforms generally requires the installation of protective enclosures to prevent personnel and objects from falling from the platform, ensuring the safety of workers at height and the safety of personnel and property in the area below. For example, during the construction of high-pier hydraulic platforms, the traditional practice is to install 1.2m high guardrails around the perimeter of the platform, enclosing them with green netting to form a protective enclosure. However, green netting enclosures are ineffective; small parts can easily fall off the platform through gaps during construction, and its low rigidity and strength make it prone to deformation and damage during construction, requiring repeated replacements. This poses certain safety hazards and results in a poor image of safe and civilized construction.

[0003] Existing technologies have proposed several protective enclosure devices for aerial platforms, generally comprising several interconnected protective nets. Adjacent nets are connected to the scaffolding steel pipes of the aerial platform via fasteners. The fasteners include clamps and connecting rods. The clamps connect to the scaffolding steel pipes, and one end of the connecting rod connects to the clamp, while the other end has a slot for engaging the protective net. However, in existing devices, the clamps are not adjustable in direction, generally only able to clamp the horizontal or vertical steel pipes of the scaffold. In actual construction, there may be mismatches between the orientation of the steel pipe and the clamp, resulting in poor flexibility. Furthermore, the connecting rods in existing devices have fixed lengths and cannot be adjusted according to the actual distance between the scaffold and the protective net. Since the distance between different protective nets and the scaffold may vary slightly, the fasteners may malfunction, failing to meet actual usage requirements. Utility Model Content

[0004] This utility model proposes a protective enclosure device for high-altitude platforms to solve the problem that existing protective enclosure devices for high-altitude platforms cannot meet actual usage requirements because the fixing components used cannot adjust the direction of the clamps and the length of the connecting rods.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A protective enclosure device for aerial platforms includes several protective structures spliced ​​together. Each protective structure includes a square frame and a perforated steel plate on the back of the square frame.

The other end of the connecting plate is provided with a first slot for engaging one protective structure, with the first slot facing the clamp. The connecting plate is provided with a second slot on one side of the first slot for engaging another protective structure, with the second slot facing perpendicular to the first slot.

[0007] Furthermore, the clamp includes a first arc-shaped clamping plate and a second arc-shaped clamping plate. One side of the first arc-shaped clamping plate is hinged to the second arc-shaped clamping plate via a hinge, and its opposite side is detachably connected to the second arc-shaped clamping plate via a locking bolt. The locking bolt is threaded with a locking nut. The first arc-shaped clamping plate is fixedly connected to the telescopic rod.

[0008] Furthermore, the telescopic rod includes a sleeve and a movable rod. The first arc-shaped clamp is provided with a first connecting block. One end of the sleeve is fixedly connected to the first connecting block, and the other end is threadedly connected to the movable rod. A rotating handle is fixedly sleeved in the middle of the movable rod. A second connecting block is provided at the end of the connecting plate away from the first slot. The second connecting block is rotatably connected to the end of the movable rod away from the sleeve.

[0009] Furthermore, the thickness of the connecting plate is 2-6mm.

[0010] Furthermore, the thickness of the perforated steel plate is 1-3mm.

[0011] Furthermore, the perforated steel plate is evenly provided with several perforated areas, with an interval of 50-150mm between two adjacent perforated areas.

[0012] Furthermore, the perforated area is square with a side length of 50-100mm.

[0013] Furthermore, the perforated area is provided with a plurality of circular holes, the diameter of which is 4-6 mm.

[0014] Furthermore, the square frame is connected with several reinforcing steel bars.

[0015] Furthermore, the thickness of the reinforcing steel strip is 4-6 mm.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] like Figure 1 As shown, a protective enclosure device for high-altitude platforms includes several protective structures 23 spliced ​​together. Figure 1 The diagram shows four protective structures 23 joined together, with two on top and two on the bottom. Each protective structure 23 includes a square frame 1 and a perforated steel plate 3 on the back of the square frame 1, the perforated steel plate 3 being 1-3 mm thick. Several reinforcing steel strips 2, each 4-6 mm thick, are connected inside the square frame 1. In this embodiment, the perforated steel plate 3 is 2 mm thick, and the reinforcing steel strips 2 are 5 mm thick.

[0030] Two adjacent protective structures 23 are connected to the scaffolding steel pipes of the high-altitude platform by fasteners 4. In this embodiment, two adjacent vertical protective structures 23 are connected to the scaffolding steel pipes by two fasteners 4, and two adjacent horizontal protective structures 23 are connected to the scaffolding steel pipes by one fastener 4.

[0031] like Figure 2-3 As shown, the fixing component 4 includes a clamp 5, a telescopic rod 12, and a connecting plate 17. The clamp 5 is detachably connected to the scaffold steel pipe. One end of the telescopic rod 12 is fixedly connected to the clamp 5, and the other end is rotatably connected to one end of the connecting plate 17. The other end of the connecting plate 17 is provided with a first slot 18 for engaging a protective structure 23, with the first slot 18 facing the clamp 5. The connecting plate 17 is provided with a second slot 19 on one side of the first slot 18 for engaging another protective structure 23, with the orientation of the second slot 19 perpendicular to the orientation of the first slot 18. The thickness of the connecting plate 17 is 2-6mm. In this embodiment, the thickness of the connecting plate 17 is 4mm. The first slot 18 is composed of an L-shaped plate and the connecting plate 17. One end of the L-shaped plate is perpendicularly connected to the connecting plate 17, and the other end is parallel to the connecting plate 17. The second slot 19 is composed of two spaced-apart clamping plates and the connecting plate 17, located on the opposite side of the connecting plate 17 connected to the L-shaped plate.

[0032] like Figure 4-5As shown, the clamp 5 can be detachably connected to the horizontal steel pipe 21 or vertical steel pipe 22 of the scaffold by rotation. When the first slot 18 is working, it engages the square frame 1 of one protective structure 23. When the second slot 19 is working, it engages the entire side of another protective structure 23 (i.e., including the square frame 1 and the steel mesh). In addition, when the fixing member 4 is used to fix two adjacent protective structures 23, the first slot 18 is located below and can hook the lower protective structure 23, so that both the upper and lower parts of the protective structure 23 can bear force, improving stability. In the prior art, the two slots at the end of the connecting rod are symmetrically arranged left and right or up and down. This structure is similar to the second slot 19 in this application. When used to fix the upper and lower protective structures 23, it does not have the function of hooking and supporting the lower protective structure 23.

[0033] Specifically, the clamp 5 includes a first arc-shaped clamping plate 6 and a second arc-shaped clamping plate 7. One side of the first arc-shaped clamping plate 6 is hinged to the second arc-shaped clamping plate 7 via a hinge 8, and its opposite side is detachably connected to the second arc-shaped clamping plate 7 via a locking bolt 9. The locking bolt 9 is threaded with a locking nut 10. The first arc-shaped clamping plate 6 is fixedly connected to the telescopic rod 12. The telescopic rod 12 includes a sleeve 13 and a movable rod 14. The first arc-shaped clamping plate 6 is provided with a first connecting block 11. One end of the sleeve 13 is fixedly connected to the first connecting block 11, and the other end is threadedly connected to the movable rod 14. A rotating handle 15 is fixedly sleeved in the middle of the movable rod 14. A second connecting block 16 is provided at the end of the connecting plate 17 away from the first slot 18. The second connecting block 16 is rotatably connected to the end of the movable rod 14 away from the sleeve 13. When the length of the telescopic rod 12 needs to be adjusted, simply hold the rotating handle 15 and drive the movable rod 14 to rotate relative to the sleeve 13. This has a tightening and fixing effect on the protective structure 23, and also has the advantages of simple structure and convenient operation.

[0034] The clamp 5 of this utility model is rotatably connected to the connecting plate 17 via the telescopic rod 12, so that the direction of the clamp 5 is adjustable. It can be connected to the horizontal steel pipe 21 of the scaffold or the vertical steel pipe 22 of the scaffold. It can connect to the appropriate steel pipe according to the actual situation, and has good flexibility and practicality.

[0035] This utility model can adjust the distance between the clamp 5 and the first slot 18 and the second slot 19 by means of the telescopic rod 12. During use, the length of the telescopic rod 12 can be adjusted according to the actual distance between the scaffold and the protective structure 23, so as to fix the protective structure 23 on the scaffold.

[0036] Example 2

[0037] like Figure 6As shown, based on Embodiment 1, in this embodiment, the perforated steel plate 3 is uniformly provided with several perforated areas, with an interval of 50-150mm between adjacent perforated areas. Each perforated area is square with a side length of 50-100mm, and each perforated area has several circular holes 20 with a diameter of 4-6mm. In this embodiment, the interval between two adjacent perforated areas is 100mm, the side length of the perforated area is 50mm, and the diameter of the circular holes 20 is 5mm. This arrangement gives the perforated steel plate 3 a better sealing effect, preventing small parts from falling out of the platform during construction, and also provides high rigidity and strength, making it less prone to deformation and damage during construction.
