Problems solved by technology

However, the existing technology has certain limitations. For example, whether it is a steel pipe trolley or a subsequently designed steel pipe welding device, there are problems of inconvenient installation and difficult movement, especially in underground projects where multiple steel pipes are operated at the same time. The design section of the transportation branch tunnel is small. If the welding device is installed multiple times in the tunnel, it will lead to long construction period and low economic value of the project.

Embodiment 2

[0039] In this embodiment, the steel pipe assembly and welding device is applied to on-site assembly and welding of large steel pipes in a certain tunnel.

[0040] Such as Figure 1 to Figure 4 As shown, a steel pipe assembly welding device includes a column 1, a beam 2 and a main body 4, the two ends of the beam 2 are connected to the column 1, the main body shaft 6 is connected with a rotary support frame 5, and the main body 4. Set above the crossbeam 2, the connection between the crossbeam 2 and the column 1 has a positioning clamping and lifting device, and the bottom of the beam 2 or the column 1 is provided with a walking device 9; The structure can reduce the height of the whole device, greatly reduce the overall volume of the device, and facilitate transportation and transfer.

[0041] Such as Figure 1 to Figure 4 As shown, the lower part of the main body 4 is connected with a horizontal turning device, and the horizontal turning device is installed on the supporting...

Embodiment 3

[0050] In this embodiment, the main difference from Embodiment 1 and Embodiment 2 is that the rotating device under the main body is changed to a translation device, and the traveling device adopts a track-type seam welding trolley.

[0051] Such as Figure 1 to Figure 4 As shown, a steel pipe assembly welding device includes a column 1, a beam 2 and a main body 4, the two ends of the beam 2 are connected to the column 1, the main body shaft 6 is connected with a rotary support frame 5, and the main body 4 is arranged above the beam 2, the lower part of the main body 4 is connected with a translation device, the connection between the beam 2 and the column 1 has positioning clamping and lifting settings, and the device is also equipped with a walking device 9.

[0052] In this embodiment, the moving direction of the translation device is perpendicular to the crossbeam, so that the main body can move towards the middle of the whole device, reducing the width of the entire assem...
