Description

Technical Field

[0001] This utility model belongs to the field of aerial work technology in construction engineering, and specifically relates to an aerial work device. Background Technology

[0002] With rapid economic development, urbanization has gradually transitioned from a phase of "new construction" to one of "renovation of existing structures." Preserving the main building structure while renovating the facade, upgrading electromechanical pipelines, and enhancing interior decoration has become a key path for improving the quality of urbanization. However, due to the irreversible nature of some renovations and other construction procedures, construction challenges have also arisen.

[0003] For example, in a renovation project, the main space of the building is a shared lobby with a clear height of 30 meters, inside which is a spherical control room with a diameter of approximately 21 meters and a dome elevation of 25.5 meters. The renovation included the partial removal of the suspended ceiling above the dome and the replacement of related electromechanical pipelines.

[0004] Because the area above the dome lacks the conditions for erecting scaffolding, and the limited space inside the shared hall prevents the use of conventional aerial work platforms such as aerial work platforms, and because the dome requires high protection, existing aerial work platforms cannot meet these construction requirements. Summary of the Invention

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0037] like Figures 1-4 As shown, this embodiment provides an aerial work device, including a safety net 3, multiple planks 2 and multiple first connecting ropes 1.

[0038] Multiple first connecting ropes 1 are used to connect to the tubular trusses 6 on both sides of the building. The multiple first connecting ropes 1 are arranged parallel to each other at intervals and located on the same plane. The first connecting ropes 1 are preferably steel wire ropes, and the diameter of the steel wire ropes is preferably 24mm.

[0039] Specifically, based on the spacing of the stress points of the tubular truss 6, a first connecting rope 1 is pulled every 2000mm, for a total of four first connecting ropes 1. According to the construction load verification, the diameter of the first connecting rope 1 can preferably be 24mm. Multiple tensioning components 4 can be fixed to the upper and lower ends of the tubular trusses 6 on both sides to ensure the lifting points are secure. Then, the two ends of the first connecting rope 1 are wrapped around the tensioning components 4. The tensioning components 4 tension and lock the first connecting rope 1, keeping it taut and achieving a certain strength and stiffness. The elevation of the four first connecting ropes 1 is controlled at 27m, 1.5m from the sphere and 1.5m from the bottom of the roof truss, ensuring sufficient working space for personnel. Furthermore, the cable-stayed working platform formed by the four first connecting ropes 1 transmits force to the tubular trusses 6 on both sides, improving the support strength and stability.

[0040] The plurality of planks 2 are laid sequentially and at intervals on adjacent first connecting ropes 1 along the extension direction of the first connecting ropes 1, and the adjacent planks 2 arranged radially along the plurality of first connecting ropes 1 are staggered. The planks 2 are preferably steel scaffold boards with specifications of JB2100*240, W240*H45, and material of Q235B.

[0041] Specifically, after the scaffolding around the sphere is erected, planks 2 can be laid sequentially from both sides towards the center of the sphere. The two ends of each plank 2 are located on two adjacent first connecting ropes 1 and are secured to the first connecting ropes 1 using steel wire, iron wire, or other fixing components. Adjacent planks 2 are spaced apart along the extension direction of the first connecting ropes 1, and are staggered along the radial direction of the four first connecting ropes 1. This spaced laying method reduces the load on the first connecting ropes 1 and also improves the stability of the construction.

[0042] The safety net 3 is laid on multiple planks 2. The safety net 3 is preferably a close-mesh net. Laying a horizontal safety net 3 close to multiple planks 2 can prevent items from falling through the gaps during construction and improve safety.

[0043] In the above structure, the tubular trusses 6 on both sides of the building's main hall serve as load-bearing support points. Multiple first connecting ropes 1 are tensioned to form a cable platform. A deck 2 and safety net 3 are laid on these first connecting ropes 1 to form a construction work platform, enabling construction workers to work in environments with limited space and strict erection requirements. This aerial work device not only improves the stability and safety of construction but also allows for simultaneous work by multiple people, thus increasing construction efficiency.

[0044] like Figure 2As shown, in a preferred embodiment, tensioning components 4 are provided at both ends of the first connecting rope 1. The tensioning components 4 are used to tension the first connecting rope 1 and fix one end of the first connecting rope 1 to the tubular truss 6. The tensioning components 4 may include a hand-operated hoist 41 and a tensioner (not shown). The hand-operated hoist 41 is used to tension the first connecting rope 1, and the tensioner is used to pull the first connecting rope 1. The hand-operated hoist 41 is preferably a 5T hand-operated hoist 41.

[0045] Specifically, first, one side of the chain hoist 41 is fixed to the upper and lower ends of the tubular truss 6 to ensure the lifting point is secure. The chain hoist 41, located at both ends of the first connecting rope 1, hooks and straightens the first connecting rope 1, applying tension to keep it taut, thus achieving a certain strength and rigidity. After the chain hoist 41 tensions the first connecting rope 1, a tensioner is installed between the chain hoist 41 and the tubular truss 6, maintaining the tension on the chain hoist 41. The tensioner performs secondary tensioning on the first connecting rope 1. When the tension value displayed on the tensioner's instrument panel reaches the set pre-tension value, tensioning stops, and the buckle on the first connecting rope 1 is locked. The reserved length at the end of the first connecting rope 1 is not less than 10m. By using the chain hoist 41 and the tensioner in conjunction, precise tensioning and fixation of the first connecting rope 1 are achieved, ensuring the supporting strength of the first connecting rope 1.

[0046] like Figure 2 and Figure 4 As shown, in a preferred embodiment, a reinforcing mesh 5 is also included, which is laid on the safety net 3. The reinforcing mesh 5 is preferably a wire mesh with specifications of 4000mm × 4000mm × 4mm and a mesh spacing of 60mm × 60mm. Multiple reinforcing meshes 5 can be laid on the safety net 3, and the size of the edge reinforcing mesh 5 can be adjusted according to the actual planar dimensions. The reinforcing mesh 5 and the first connecting rope 1 are bound and fixed with wire, serving a limiting function. The installation of this reinforcing mesh 5 facilitates the balancing of the force on the deck 2 and improves the overall stability of the cable platform, preventing slippage between the first connecting rope 1 and the deck 2.

[0047] In a preferred embodiment, a protective net (not shown) is also included, arranged circumferentially along a plurality of first connecting ropes 1. This protective net is used to connect to the suspension rods on the tubular truss 6 via second connecting ropes. The second connecting ropes are preferably steel wire ropes. Four second connecting ropes with a diameter of 12mm are stretched along the cable platform on the suspension rods. The upper end of the protective net is attached to these four second connecting ropes, and the lower end of the protective net is tied to the first connecting ropes 1. The height of the protective net is 1.5m, ensuring the safety of the working platform's edges.

[0048] In a preferred embodiment, multiple safety ropes (not shown) are also included. One end of each safety rope is connected to a suspension rod on the tubular truss 6, and the other end is connected to the safety belt of the construction worker. The safety ropes are preferably steel wire ropes. Two safety ropes with a diameter of 12mm can be installed, with a spacing of 8m between them. The safety ropes are located in the middle area of ​​the cable platform, with one end connected to the suspension rod and the other end equipped with a locking buckle that is securely connected to the safety belt of the construction worker. This arrangement improves the safety of the construction worker and avoids the risk of overturning.

[0049] In a preferred embodiment, the scaffold planks are made of metal. The metal material can be carbon structural steel (Q235), aluminum alloy, etc. Carbon structural steel (Q235) has advantages such as high strength and durability. Aluminum alloy has advantages such as light weight and corrosion resistance.

[0050] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
