For the damper with unadjustable length, if the length of the first damper 5 and the distance between the anchor seat 23 and the first sleeve hoop 31 do not match or the length of the second damper 6 and the distance between the anchor seat 23 and the second sleeve hoop 32 do not match, the mounting bolt connecting the anchor seat 23 and the cross beam 21 is removed, the anchor seat 23 is moved along the length direction of the cross beam 21 to a proper position, and it is ensured that the first damper 5 and the second damper 6 can be connected with the anchor seat 23 and the first sleeve hoop 31 or the second sleeve hoop 32, then the mounting bolt is inserted through the first connection hole 211 of the cross beam 21 and the corresponding second connection hole 234 of the anchor seat 23, so as to prevent the anchor seat 23 from moving randomly.

[0068] S7, the arch rib segment 9 is bound on the arch rib placing platform 2 by using the cable wind rope 7. In the embodiment, the transverse front cable wind rope 711 and the longitudinal front cable wind rope 712 of the front cable wind rope group 71 before binding, and the transverse rear cable wind rope 721 and the longitudinal rear cable wind rope 723 of the rear cable wind rope group 72 after binding are tensioned by using the chain hoist after installation is completed.

[0069] S8, after inspection is completed, the flatbed transport vehicle 1 is driven to transport. When the arch rib segment 9 reaches the destination, the cable wind rope 7 is in a relaxed state by operating the chain hoist, then the connection between the cable wind rope 7 and the anchor seat 23 is disconnected, and the cable wind rope 7 is removed; then the first damper 5 is disconnected with the anchor seat 23 and / or the first sleeve hoop 31, and the second damper 6 is disconnected with the anchor seat 23 and / or the second sleeve hoop 32 by pulling out the pin shaft 38 and / or the insertion pin 34, then the connecting bolt 35 is removed, so that the two hoop plates 33 are separated, and then the first sleeve hoop 31 and the second sleeve hoop 32 are removed from the arch rib segment 9, finally the arch rib segment 9 is lifted from the flatbed transport vehicle 1 to a designated position.

[0070] Compared with the previous transportation mode, the transportation mode has lower requirements for the transportation channel, and the longitudinal slope and transverse slope requirements can be met by the general highway, without further requirements for the flatness. Meanwhile, the transportation mode can also adapt to general curved transportation, and has lower investment cost. Compared with the rail flat car, the transportation mode does not need additional investment of transportation track, and the cost and rent of the flatbed transport vehicle 1 are lower than those of the self-propelled hydraulic module vehicle. The transportation mode is suitable for long-distance transportation. The transportation length of the flat car and the self-propelled hydraulic module vehicle is generally not more than 1km, while the transportation distance of the flatbed transport vehicle can greatly exceed the transportation range of the flat car and the self-propelled hydraulic module vehicle.

[0071] In the prior art, when the flatbed transport vehicle 1 is used for long-distance transportation of the arch rib segment 9, the arch rib segment 9 is usually bound to the vehicle body by a rope. However, when the flatbed transport vehicle 1 is used for long-distance transportation on the highway, it is inevitable to encounter sudden braking or vibration of the vehicle body due to uneven road surface, which causes the arch rib segment 9 and the rope to be subjected to a large impact. In the case of tight rope, the rope is prone to breakage, which may cause danger. Therefore, at present, the arch rib segment 9 with a large weight is usually transported by the flat car and the self-propelled hydraulic module vehicle. However, the flat car and the self-propelled hydraulic module vehicle can only run on the road with high flatness, small longitudinal slope and large curved radius, which makes it difficult to meet the requirements of long-distance transportation.

[0072] The transportation device for the arch rib segment of the concrete-filled steel tube arch bridge of the embodiment fixes the arch rib placing platform 2 on the flatbed transport vehicle 1, and then binds the arch rib segment 9 to the arch rib placing platform 2 by the cable wind rope 7. Meanwhile, the arch rib segment 9 is connected to the arch rib placing platform 2 by the two rows of first dampers 5 and second dampers 6, which not only can further position the arch rib segment 9 to prevent the arch rib segment 9 from moving relative to the arch rib placing platform 2 during transportation, but also can absorb the impact force of the arch rib segment 9 and the rope when the arch rib segment 9 and the rope are subjected to an impact, so as to avoid the breakage of the rope, thereby reducing the requirements for the transportation channel.

[0073] In addition, the transportation device for the arch rib segment of the concrete-filled steel tube arch bridge of the embodiment connects the first dampers 5 and the second dampers 6 to the lower chord tube of the arch rib segment 9, and connects the cable wind rope 7 to the upper chord tube or the upper web tube 931 of the arch rib segment 9, which can make the arch rib segment 9 more stable during transportation.

[0074] It can be understood that the number of the cross beams 21, the longitudinal beams 22, the anchoring seats 23, the first dampers 5, the second dampers 6 and the cable wind ropes 7 can also be set to other numbers according to actual needs.

[0075] It can be understood that the bottom plate 231 of the anchoring seat 23 can also be connected to the arch rib placing platform 2 by other ways, for example, can be fixed to the arch rib placing platform 2 by welding or the like.

[0076] It can be understood that the structure of the arch rib setting platform 2 is not limited to the embodiment, and other frame bodies or plate structures can also be provided.

[0077] The above description is a detailed description of the preferred embodiments of the present application, but the embodiments are not intended to limit the scope of the patent application of the present application. Any equivalent changes or modifications made under the technical spirit of the present application should be included in the scope of the patent application of the present application.
