[0055] In this embodiment, the upper crossbeam 7 is vertically welded to the top of the main truss structure. The upper crossbeam 7 is welded to the push seat 202 between the two rollers 203. The rollers 203 are moved by the drive assembly, thereby moving the work platform 5 to meet the work requirements of the entire work surface.

[0056] In this embodiment, the roller 203 is a steel pulley with an outer diameter of 140mm and an inner diameter of 68mm. Of course, the size of the roller 203 can be adjusted according to the size of the track 204.

[0057] A 67mm diameter wedge is provided in the middle of the roller 203. After the decorative hanging basket is pushed into place, a steel wedge 201 is used to plug the roller 203 to prevent it from continuing to slip, thereby ensuring the stability of the device during operation. The diameter of the wedge is adjusted accordingly based on the inner diameter of the roller 203.

[0061] In this device, all the above-mentioned structural steel, channel steel, angle steel and steel plates are made of Q235 steel, and all welding is full welding.

[0062] In summary, the construction process of the decorative hanging basket device for the ultra-wide concrete main girder of the cable-stayed bridge is as follows:

[0063] 1. The hanging basket hook 4, the working platform 5, the walking system 2 and the drive components are processed on the platform below the concrete main beam 1.

[0064] 2. For example Figure 5 , 6 As shown, the track 204 is welded and fixed on the embedded steel plate 206, and the roller 203 and the push seat 202 are installed on the track 204.

[0065] 3. For example Figure 1 , 3 As shown, on the platform below the concrete main beam 1, two cranes are used to hoist the completed work platform 5 to the designated height.

[0066] 4. For example Figure 1 , 3 As shown, the working platform 5 is temporarily fixed below the concrete main beam 1 by the temporary hanger 11 arranged in advance through the hanger crossbeam 12.

[0067] 5. For example Figures 1-10 As shown, the basket hook 4 is hoisted as a whole. The socket beam 8 and the insertion beam 9 at the bottom of the basket hook 4 are aligned with the pin holes of the Bailey beam 3. After alignment, four Bailey beam pins 303 are installed to achieve the connection between the basket hook 4 and the Bailey beam 3.

[0068] 6. For example Figures 1-6 As shown, the upper crossbeam 7 of the hanging basket hook 4 is placed on the push seat 202 and welded firmly. If the gap between the upper crossbeam 7 and the push seat 202 is large during installation, a steel plate can be inserted between the upper crossbeam 7 and the push seat 202 and then welded and fixed.

[0069] 7. For example Figure 1 As shown, two reinforcing tie rods 6 are installed, and the two ends of the reinforcing tie rods 6 are welded and fixed to the distribution beam 502 and the hanging basket hook 4, respectively.

[0070] 8. For example Figure 1 , 3 As shown, remove the temporary hanging rod 11, and the installation of the decorative hanging basket is now complete.

[0071] 9. For example Figure 5 , 6 As shown, a manual hoist 208 is used to pull the pusher 202, which in turn moves the decorative hanging basket forward.

[0072] 10. For example Figures 1-10 As shown, after the decorative hanging basket is used, the temporary hanging rod 11 is reinstalled, and the decorative hanging basket is removed in the reverse order of installation steps 2 to 7.

[0073] In summary, the decorative hanging basket device for ultra-wide concrete main beams of cable-stayed bridges of this utility model has a simple structure, is easy to process and manufacture, has strong adaptability, and low cost.
