[0001] This utility model relates to the field of steel structure construction technology, specifically to a welding operation platform for the installation of arch rib segments of a steel structure arch bridge. Background Technology

[0002] With the rapid development of arch bridge construction technology in my country, the requirements for practicality and aesthetics are increasing. Steel structures are widely used in the foundation construction of steel box arch bridges, playing an extremely important role in long-span arch bridges.

[0003] Publication No. CN219805569U discloses a welding operation platform for the installation of arch rib segments in steel structure arch bridges. This platform solves the problems of high difficulty, high risk, and increased cost associated with existing steel box arch rib assembly construction, while simultaneously reducing welding efficiency and quality. However, in practice, the assembly process is cumbersome and requires the assistance of other equipment to adjust the suspended platform for spatial adjustment, which is time-consuming, labor-intensive, and relatively inefficient. Therefore, we propose a welding operation platform for the installation of arch rib segments in steel structure arch bridges. Utility Model Content

[0026] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0027] Please see Figure 1-3 This utility model provides an installation and welding operation platform for arch rib segments of a steel structure arch bridge, including a splicing base plate 1. Insertion base columns 7 are fixedly installed around the perimeter of the splicing base plate 1. Multiple parallel sliding guardrails 9 are provided between adjacent insertion base columns, and the distance between adjacent sliding guardrails 9 is adjustable. The top of each insertion base column 7 is fixedly connected to a top protective plate 13. In use, firstly, the splicing structure, which facilitates easy disassembly and installation, allows for faster overall assembly and fixing of the operation platform. Secondly, the flexible and reliable lifting equipment allows the operation platform to reach the designated work area at any time, making entry, exit, installation, and disassembly more convenient. This reduces the difficulty of aerial construction for workers, ensures personal safety, and improves work efficiency.

[0028] In this embodiment, as Figure 2As shown, the insertion base column 7 is a square base column, with vertical grooves 8 on each of its two adjacent sides. Sliding inserts 10 are respectively provided at both ends of the sliding guardrail 9 to cooperate with the vertical grooves 8. To make the distance between adjacent sliding guardrails 9 adjustable, adjustable sliding elements 11 are provided between two adjacent sliding guardrails, inserted into the vertical grooves. Specifically, each sliding guardrail 9 has a sliding insert 10 fixed at both ends that slides within the sliding adjustment rod 8, with an adjustable sliding element 11 inserted at intervals. In use, the distance between the sliding guardrails 9 is controlled by adjusting the sliding elements 11. The lengths of the adjustable sliding elements 11 are not uniform; adjusting the length of the sliding elements 11 adjusts the distance between two sliding guardrails 9, facilitating welding work or tool retrieval. In this embodiment, the sliding guardrail 9 comes in two types depending on the platform's length and width, and each type of sliding guardrail 9 has a different length.

[0029] like Figure 3 As shown, the plug-in base column 7 is fixed to the splicing base plate 1 by the fixing plug 4 and fasteners. Specifically, the fixing plug 4 includes a square mounting base 5 and the bottom part of the plug-in base column inserted into the square mounting base 5. The square mounting base is fitted onto the plug-in base column 7, wherein the bottom end of the plug-in base column 7 protrudes beyond the square mounting base. The square mounting base and the plug-in base column 7 are welded together. The bottom of the plug-in base column 7 is provided with a insertion hole for inserting the bottom fixing member 12. During assembly, the fixing plug 4 and the plug-in base column 7 are fixedly connected together.

[0030] The splicing base plate 1 is provided with a splicing groove 2, and the fixing plug 4 is inserted into the splicing groove 2. The surface of the splicing base plate 1 has a plurality of splicing fixing holes 3 on the outer periphery of the splicing groove 2, and the surface of the mounting base has a fitting fixing hole 6 that matches the splicing groove. The fixing plug 4 is fixed to the splicing base plate 1 by setting fasteners in the splicing fixing holes 3 and the fitting fixing holes 6.

[0031] In this embodiment, as Figure 1 As shown, the top of the plug-in base column 7 is fixedly connected to the top protective plate 13 by bolts. In use, the top protective plate 13 prevents falling objects from above from hitting the workers inside the operating platform.

[0032] The working principle and usage process of this utility model are as follows: First, the splicing base plate 1 is welded to the target area to fix the base. Then, the insertion base column 7 under the mounting base 5 is aligned with the splicing groove 2 opened on the surface of the splicing base plate 1 and inserted. Bolts are then used to connect and fix the base by passing through the fitting fixing hole 6 and the splicing fixing hole 3. The base fixing component 12 is inserted into the fixing plug 4 for auxiliary fixing. After the four mounting bases 5 are fixed, the sliding plugs 10 at both ends of the sliding guardrail 9 are slid into the sliding adjusting rod 8 from the insertion base columns 7 on both sides. Then, according to requirements, different numbers of adjusting sliding components 11 are inserted between the sliding guardrails 9 to adjust the gap size, thus completing the guardrail installation. Assemble the equipment, then align the top protective plate 13 with the mounting base 5 and insert it, securing it with bolts to complete the connection and fixation of the entire equipment. When using it at height, if it is necessary to change the spacing between the sliding guardrails, the safety protection structure of the temporary adjustment port opened in the center of the plug-in base column 7 can be removed. The safety protection structure includes a groove set on one side of the vertical sliding groove of the plug-in base, with a detachable sliding frame connected to the groove. The sliding frame is fixed in the groove with bolts. By removing the bolt-fixed sliding frame, the sliding guardrail 9 and the adjusting sliding component 11 can be added or removed. After completing the temporary adjustment at height, the sliding groove frame insert is then fixed to prevent the sliding guardrail 9 and the adjusting sliding component 11 from falling off.

[0033] During construction, operators can stand inside the sliding guardrail to work. By adjusting the spacing of the sliding guardrail, the working conditions can be adjusted to be easy for the operators to work in. This not only ensures the personal safety of the operators, but also further improves the installation and dismantling efficiency of the entire device.

[0034] The embodiments described above are some, but not all, embodiments of this utility model. The detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
