The spring 1 42 causes the collection box 45 to expand slowly, so that the collection box 45 is below the wet joint welding position. When welding the wet joint, the collection box 45 can collect the fallen welding slag; by setting the collection component 4, especially the cooperation between the collection box 45 and the hinge 2 44 and the rotating shaft 43, the welding slag can fall directly into the collection box 45 during the welding process, reducing the problem of welding slag scattering and polluting the environment, and also reducing the safety threat of welding slag to workers, thereby improving safety during welding; the sliding rod 31 in the support component 3 and the spring 1 42 in the collection component 4 ensure the stable support of the collection box 45 below the wet joint welding position, and the collection box 45 can expand slowly; the sliding rod 31 allows the sliding rod 31 to be slid into the bottom plate 1 when stored, reducing its volume for easy storage.

[0025] Further, such as Figure 1 、 4As shown in Figure 5, two electric push rods 32 are installed at the bottom of the sliding rod 31; the bottom of the electric push rod 32 is fixedly connected to a connecting plate 34; the bottom of the connecting plate 34 is installed with a support frame 33; the two ends of the rotating shaft 43 are fixed on the connecting plate 34; the collecting box 45 is overlapped on the connecting plate 34; when working, the connecting plate 34 and the support frame 33 are pushed by the electric push rod 32, thereby driving the collecting assembly 4 to move downward, so that the platform can adapt to wet joints of bridges of different thicknesses, thereby improving the versatility and practicality of the construction platform, so that a single platform can be used for wet joint welding work of various thicknesses, reducing construction cost and time; since it can adapt to wet joints of different thicknesses, the construction platform does not need to be frequently replaced or adjusted, thereby greatly reducing construction preparation time. In addition, the introduction of the electric push rod 32 also makes operation simpler and faster, further improving construction efficiency; the control method of the electric push rod 32 is usually relatively simple, and the operator only needs basic operation training to master it, which reduces the difficulty of operation and improves the ease of use of the construction platform.

[0026] Further, such as Figure 2 、 3 As shown, a reinforcement member 5 is connected to the base plate 1; a clamping groove 6 is provided on the base plate 1; the reinforcement member 5 includes a reinforcement rod 51; two clamping blocks 52 are fixedly connected to the reinforcement rod 51; the clamping block 52 is clamped in the clamping groove 6; a plurality of connecting bolts 53 are threadedly connected to the clamping block 52; when working, the connecting bolts 53 on the clamping block 52 are removed, and then the clamping block 52 is separated from the clamping groove 6, the auxiliary member 9 is separated from the base plate 1, and then the two base plates 1 are combined together by the hinge 2, thereby reducing their volume for easy storage. When welding, the base plate 1 is as described above, and the reinforcement rod 51 strengthens the supporting force of the clamping block 52, so that the platform is more stable when in use.

[0027] Further, such as Figure 1 、 2 As shown, the auxiliary part 9 includes a support rod 91; two support rods 91 are provided; a slide groove 92 is opened on the support rod 91; a sliding frame 93 is slidably connected in the slide groove 92; a support column 94 is fixedly connected to the sliding frame 93; two support columns 94 are fixedly connected to the same rainproof plate 95; when working, the sliding frame 93 is slid so that the sliding frame 93 slides in the slide groove 92 on the support rod 91, and then the sliding frame 93, the rainproof plate 95 and the support column 94 are separated from the base plate 1, making it more convenient to store. The existence of the rainproof plate 95 provides additional protection for welding work. When welding on rainy days or in a humid environment, the rainproof plate 95 can reduce rainwater entering the welding area and affecting the normal progress of the welding work. On sunny days, sunshade is provided to reduce direct sunlight on the construction workers, thereby improving the comfort of the working scene during welding.

[0028] Further, such as Figure 2 As shown, a tool slot 8 is provided on the base plate 1; four moving wheels 7 are installed at the bottom of the two base plates 1; when working, a welding device can be placed in the tool slot 8 to reduce the risk of the welding device falling when the platform is moved.

When welding the wet joint, the collection box 45 can collect the fallen welding slag; when working, the electric push rod 32 pushes the connecting plate 34 and the support frame 33, thereby driving the collection assembly 4 to move downward, so that the platform can adapt to bridge wet joints of different thicknesses, thereby improving the versatility and practicality of the construction platform, so that a single platform can be used for wet joint welding work of various thicknesses; when working, the connecting bolt 53 on the clamping block 52 is removed, and then the clamping block 52 is separated from the clamping slot 6, and the auxiliary part 9 is separated from the bottom plate 1, and then the two base plates 1 are put together through hinge 1 2, thereby reducing its volume for convenient storage; when working, the sliding frame 93 is slid so that the sliding frame 93 slides in the slide groove 92 on the support rod 91, and then the sliding frame 93, the rainproof plate 95 and the support column 94 are separated from the base plate 1, making storage more convenient. The existence of the rainproof plate 95 provides additional protection for welding work. When welding in rainy days or humid environments, the rainproof plate 95 can reduce rainwater from entering the welding area and affecting the normal progress of welding work. On sunny days, sunshade is provided to reduce direct sunlight on construction workers; welding devices can be placed in the tool slot 8 to reduce the risk of the welding device falling when the platform is moved. The moving wheels 7 make the entire platform easy to move on the construction site, whether from one welding position to another or when the welding angle or position needs to be adjusted, it can be completed quickly and accurately. The platform is mobile, which means that it can be easily moved to the wet joint position where welding is required.
