[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] A construction device for a special-shaped metal canopy for a stadium, comprising a cantilever erection unit 1 directly connected to a steel structure 4 of the stadium, and a cantilever erection unit 2 indirectly connected to the steel structure 4 of the stadium. The cantilever erection unit 1 and the cantilever erection unit 2 are both slidably connected to a hanging basket 3. A plurality of the cantilever erection units 1 and 2 are arranged along the circumference of the stadium. The stadium has a large area, and a plurality of the cantilevered erection units 1 and the cantilevered erection units 2 2 are arranged along the circumference of the stadium, which can improve construction efficiency, optimize the installation and use process of the hanging basket, reduce the movement and adjustment time of the hanging basket, improve the continuity and efficiency of construction, and help shorten the construction period. Reasonable construction organization and arrangement enable each construction link to be closely connected, avoiding unnecessary waiting and delays; in view of the special construction environment and steel structure shape of the stadium, the utility model connects the hanging basket 3 to the stadium steel structure 4 in a detachable manner directly or indirectly, can flexibly adapt to various complex steel structure conditions, can carry out all-round construction of the stadium, and ensure the smooth progress of construction; the cantilevered erection unit 1, the cantilevered erection unit 2, and the hanging basket 3 are simple and convenient to produce, with low cost, and can also reduce the cost investment in labor, equipment, etc., thereby reducing the overall construction cost.

[0046] Specifically, if Figure 1 、 Figure 2 As shown, for the curved surface area of ​​the stadium, the unique shape of the steel structure precludes standard installation methods. Instead, the present invention utilizes a cantilevered installation unit 1, directly connected to the steel structure, to ensure the stability of the hanging basket 3. The cantilevered installation unit 1 is lowered to the ground via the basket's boom, enabling the hanging basket 3 to operate within the specialized structural area. For the stadium's rooftop area, the use of a cantilevered installation unit 2 2 adapts to the unique characteristics of the stadium's steel structure and ensures the safety and stability of the hanging basket 3 during construction.

[0047] On the basis of the above embodiment, as a preferred embodiment, Figure 3 、 Figure 4 As shown, the cantilever erection unit 2 includes a support rod 21 connected to the stadium steel structure 4 through a connector 22, the outer periphery of the support rod 21 is connected to a steel wire rope 23 through a connector 24, the other end of the steel wire rope 23 is connected to the lifting unit 31 of the hanging basket 3, and at least four connectors 24 are provided.

[0048] On the basis of the above embodiment, as a preferred embodiment, a rubber piece is provided between the support rod 21 and the stadium steel structure 4 .

[0049] Specifically, the support rod 21 adopts a 100×100×5mm square tube, which is set on the stadium steel structure 4, such as the roof. The connecting piece 22 can be made of steel rope or steel wire, and the front and rear ends of the square tube are fixed to the steel structure by steel rope or steel wire, and anti-wear facilities are provided, and rubber pads are added to increase friction.

[0050] Preferably, the steel wire rope 1 23 is wound around the stadium steel structure 4 and the square tube, with multiple turns to enhance stability. The second connector 24 uses a steel wire rope clamp, and at least four steel wire rope clamps are used to clamp the steel wire rope 1 23. 8# channel steel is used on both sides of the square tube for secondary fixation, and the connection form is bolt connection (M12*140).

[0051] On the basis of the above embodiment, as a preferred embodiment, a limiting structure is provided on the support rod 21, such as a limiting groove or a limiting ring, and the limiting groove or the limiting ring is provided along the length direction of the support rod 21, and the steel wire rope 23 is arranged along the inside of the limiting groove or passes through the limiting ring to prevent the steel wire rope 23 from deviating and causing safety hazards.

[0052] On the basis of the above embodiment, as a preferred embodiment, the end of the support rod 21 extends out of the stadium steel structure 4, and the hanging basket 3 is cantilevered outside the stadium steel structure 4, especially for the construction of the stadium roof position, such as Figure 3 shown.

[0053] On the basis of the above embodiment, as a preferred embodiment, Figure 5-Figure 8 As shown, the cantilever erection unit 1 includes a steel wire rope 2 11 wound on the stadium steel structure 4. The cantilever erection unit 1 can be connected to any stadium steel structure 4. One end of the steel wire rope 2 11 is connected to the steel wire rope 2 11 through a connector 3 12, and the other end of the steel wire rope 2 11 is connected to the lifting unit 31 of the hanging basket 3.

[0054] Specifically, the load capacity of the hanging basket 3 connected to the cantilevered erection unit 2 is limited from the rated load of 630 kg to 400 kg to improve the safety factor. The connecting piece 3 12 adopts a wire rope clamp. The end of the wire rope 2 11 is directly tied to the stadium steel structure 4, with no less than two turns, and fixed with four wire rope clamps. Figure 7 As shown, preferably, the spacing between the wire rope clamps is about 60 mm, and the spacing between the wire rope clamps at the observation port is about 100 mm.

[0055] On the basis of the above embodiment, as a preferred embodiment, the steel wire rope 1 23 and the steel wire rope 2 11 are both provided with a travel limit plate 33, and the travel limit plate 33 is arranged on the hanging basket 3, which can ensure that the steel wire rope 1 23 and the steel wire rope 2 11 are separated from the exterior of the stadium by a certain distance, usually about 600 mm from the exterior or outer wall of the stadium.

[0056] Specifically, if Figure 9 As shown in the figure, it is a schematic diagram of the hanging basket 3. The bottom plate is raised by more than 200mm and laid flat. The joints of each basic section are aligned, and the basket pieces are installed. The lower basket piece is placed on the side of the working surface and connected with bolts. After pre-tightening, the entire platform frame is ensured to be straight. The lifting unit 31 includes a hoist. The hoist is installed at both ends of the side basket. During installation, it is important to make sure that the safety lock faces the outside of the platform. After installation, all connecting bolts are evenly tightened and equipped with a safety lock. Strict safety inspections and debugging are carried out on each component and operating process of the hanging basket, which effectively reduces the safety risks of the hanging basket tilting, falling, etc. during construction, protects the lives of construction workers, ensures the stability and reliability of the hanging basket during use, and reduces the occurrence of safety accidents.

[0057] On the basis of the above embodiment, as a preferred embodiment, Figure 10 As shown, a safety wire rope 32 is provided on the hanging basket 3, and the other end of the safety wire rope 32 is connected to the ground.

[0058] Preferably, the ground is connected to an embedded plate 42 via expansion bolts 41 , and the safety wire rope 32 is connected to a ring on the embedded plate 42 .

[0059] Specifically, the safety wire rope 32 provides a safety backup: its primary function is to serve as a safety backup. If the working wire rope is unable to properly support the basket and its load due to various reasons (such as wear, breakage, or tripping), the safety wire rope can immediately take over the load-bearing function of the working wire rope, preventing the basket from falling and providing a final safety guarantee for the workers inside the basket.

[0060] Specifically, the safety wire rope 32 is independent of the working system: it is independently installed in the suspension and operation system of the hanging basket from the working wire rope. Even if the hoist or other related equipment on which the working wire rope is mounted fails, the safety wire rope can still maintain effective support for the hanging basket through its own suspension device (such as an independent safety lock), ensuring that the hanging basket will not suddenly lose control and fall.

[0061] Specifically, the safety wire rope 32 can trigger the safety device: when used in conjunction with the safety lock, once the working wire rope has an abnormality and the hanging basket has an abnormal descending speed or displacement, the safety wire rope can cause the safety lock to act quickly, lock the safety wire rope, and fix the hanging basket in the current position, further enhancing the safety of the entire hanging basket system in an emergency.

[0062] On the basis of the above embodiment, as a preferred embodiment, a guide wire rope 34 is provided between the hanging basket 3 and the stadium steel structure 4 .

[0063] Specifically, the guide wire rope 34 has a stable trajectory, providing a relatively fixed guide path for the basket's lifting operation. As the basket moves up and down along the building's facade, it ensures smooth movement in the set direction, preventing the basket from swinging sideways or deviating from the predetermined lifting path, thereby ensuring the safety of workers inside the basket and ensuring operational accuracy.

[0064] Specifically, the guide wire ropes 34 can share some of the load: Although the main load-bearing structure of the hanging basket is its own standing mechanism and working wire ropes, the guide wire ropes can also, to a certain extent, share some of the loads such as lateral forces. When encountering external factors such as wind, the guide wire ropes can help resist the tendency of the hanging basket to deviate laterally due to wind, reducing the additional non-vertical loads borne by the main load-bearing components such as the working wire ropes and the standing mechanism, helping to extend the service life of these key components and maintain the stability of the entire hanging basket system.

[0065] Specifically, the guide wire rope 34 enhances overall structural rigidity: Working in conjunction with the other components of the hanging basket, it strengthens the structural rigidity of the entire hanging basket system. This allows the hanging basket to maintain a relatively stable form even under complex working conditions (such as those subject to certain levels of vibration and sway at the construction site), preventing deformation and distortion of the hanging basket structure due to excessive flexibility, which could be detrimental to safe operation. This further improves safety and reliability during operation.

[0066] Specifically, the guide wire rope 34 assists in positioning and docking: when the hanging basket needs to be accurately docked at a specific floor or operating position, the guide wire rope can play a role in assisting positioning. By observing the relative position of the hanging basket and the guide wire rope, the operator can more accurately control the lifting height and docking point of the hanging basket, facilitating operations such as loading and unloading materials and allowing personnel to enter and exit the hanging basket and enter the building interior.
