Specifically, the two ladders 1 are symmetrically arranged. The two ladders 1 can be vertically arranged and back-to-back arranged. The two ladders 1 are arranged at intervals, that is, the two ladders 1 are side by side and at intervals. The cross beam 2 is arranged between the two ladders 1. And the two ends of the cross beam 2 are respectively connected to the tops of the two ladders 1. The cross beam 1 and the two ladders 2 form a portal-shaped construction scaffold to be erected on the pipeline to be welded, and climbing and standing construction can be carried out through the ladders. In this embodiment, the cross beam 2 and the two ladders 1 can be fixed by welding or by bolts to form an integrated portal-shaped construction scaffold. To further ensure the safety of construction workers, preferably, a ladder guardrail 6 is provided on the ladder 1. In particular, the ladder guardrail 6 is provided on the side of the ladder 1 facing away from the other ladder 1, that is, on the back side between the two ladders 1, to protect the construction workers on this ladder 1 and effectively improve the work safety of the workers. Among them, the ladder guardrail 6 can be fixedly installed on the ladder 1 by welding or bolts.
[0023] The arc-shaped pipe support 3 is arranged below the cross beam 2 and is used to be sleeved on the pipeline to be welded (not shown in the figure) to support the portal-shaped construction scaffold through the pipeline to be welded, and welding construction operations can be carried out on the pipeline to be welded through the ladder 1. Specifically, the arc-shaped pipe support 3 is arranged below the cross beam 2 and is placed between the two ladders 1. That is to say, the arc-shaped pipe support 3 is placed inside the portal-shaped construction scaffold and below the cross beam 2. The arc-shaped pipe support 3 and the portal-shaped construction scaffold can be connected through a frame body such as an inclined support or directly connected. For example, the arc-shaped pipe support 3 and the intermediate connecting frame, and the intermediate connecting frame and the portal-shaped construction scaffold are fixedly connected by welding or bolts. The support of this device is realized by sleeving the arc-shaped pipe support 3 on the upper part of the pipeline to be welded, so that the staff can operate on the pipeline to be welded on this device.
[0024] To facilitate the movement of the portal-shaped construction scaffold, the moving wheels 4 are arranged on the inner side of the arc-shaped pipe support 3 in a rotatable manner and are used to abut against the outer wall of the pipeline to be welded, so as to drive the portal-shaped construction scaffold to move horizontally along the length direction of the pipeline to be welded through the frictional force with the pipeline to be welded.

A moving runner 4 is rotatably provided on the runner frame 8, that is, the moving runner 4 is arranged on the runner frame 8 in a rotatable manner so that the side wall of the moving runner 4 abuts against the outer wall of the pipeline to be welded. The driving member 7 may be a handheld grip ring, which may be fixedly connected to the upper end face of the moving runner 4. During use, by rotating the handheld grip ring, the moving runner 4 can be rotated accordingly to perform a lateral movement through the frictional action with the pipeline to be welded, facilitating the timely movement requirement of the worker during welding.
[0025] To reduce the friction between the arc-shaped pipe rack 3 and the arc-shaped pipe rack of the pipeline to be welded during the lateral movement, preferably, rolling wheels 5 are provided inside the arc-shaped pipe rack 3.

Specifically, there may be multiple rolling wheels 5, which are arranged at intervals in an annular array on the arc-shaped pipe rack 3. That is to say, the rolling wheels 5 are annularly arrayed and spaced on the lower side of the arc-shaped pipe rack 3, and the rolling wheels 5 are rotatably arranged on the arc-shaped pipe rack 3, enabling the device to move laterally conveniently under the rolling action of the rolling wheels 5 and effectively improving the work efficiency. Among them, the rolling wheels 5 may be rubber wheels or other materials, and no specific limitation is made in this embodiment.
[0026] In this embodiment, to improve the stability of the device, preferably, side support feet 9 are provided on the opposite inner sides of the two ladders 1 for abutting against the outer wall of the pipeline to be welded. Specifically, several layers of side support feet 9 are provided at intervals on the ladder 1.

Each layer of side support feet 9 has two, and the two side support feet 9 are on the same horizontal plane and can abut against the outer wall of the pipeline on the same plane to prevent the device from tilting. Among them, the side support feet 9 are horizontally arranged.
[0027] To further ensure the stability of the side support feet 9 in supporting the outer wall of the pipeline, preferably, at the end of the side support feet 9 far from the ladder 1 (such as Figure 1 the right end of the left side support foot 9 as shown), a buffer anti-slip block 10 is provided, which abuts against the outer wall of the pipeline to be welded, effectively increasing the anti-slip property and avoiding mechanical scratching of the outer wall of the pipeline. Among them, the buffer anti-slip block 10 may be a buffer rubber block or other materials, and no specific limitation is made in this embodiment.

Specifically, the side support feet 9 can be fixedly connected to the ladder 1 by bolts, facilitating the adjustment of the structural position, that is, facilitating the adjustment of the position of the side support feet 9 to adapt to the diameter of the pipeline to be welded, so that the side support feet 9 are fixedly installed at the adapted position. Of course, the side support feet 9 can also be slidably arranged on the ladder 1 along the length direction of the ladder 1 (such as Figure 1 in the vertical direction shown) so as to be slid to the adapted height position.
[0029] In another implementation manner of the arrangement of the side support feet in this embodiment, the side support feet 9 can be telescopic members to adjust the length of the side support feet 9 by telescoping, so that the end of the side support feet 9 can abut against the outer wall of pipelines with different diameters.

The telescopic member can include: a fixed section 91 and at least one sliding section 92; wherein, the sliding sections 92 are all arranged on one side of the fixed section 91 (such as Figure 2 in the right side shown), the first-stage sliding section 92 is sleeved in the fixed section 91 and relatively slides with the fixed section 91 through adjustment to adjust the total length of the sliding section 92 and the fixed section 91. Any two adjacent sliding sections 92 are slidably connected to adjust the total length of the sliding sections 92. Specifically, to increase the range and stability of the length adjustment of the telescopic member, those skilled in the art can understand that there can also be two or more sliding sections 92. A plurality of corresponding positioning holes 93 are arranged on both the fixed section 91 and the sliding sections 92, and the fixed section 91 and the first-stage sliding section 92 are connected by a positioning member 94 passing through the positioning holes 93, and / or, any two adjacent sliding sections 92 are connected by a positioning member 94 passing through the positioning holes 93. Among them, a plurality of positioning holes 93 are arranged along the length direction at the sliding end of the fixed section 91 and at both ends of the sliding sections 92. The first-stage sliding section 92 and the fixed section 91 are connected by the positioning member 94 being positioned on different positioning holes 93 on the fixed section 91 and different positioning holes 93 on the sliding sections 92 to adjust the total length of the telescopic structure 4. Of course, the sliding sections 92 can also be adjusted in this way, or alternatively, a positioning hole 93 is arranged at the sliding end of the fixed section 91, a positioning hole 93 is arranged at one end of the sliding section 92, and a plurality of positioning holes 93 are arranged at the other end. By aligning the positioning hole at the sliding end of the fixed section 91 with the end of the sliding section 92 provided with a plurality of positioning holes 93, the length can be adjusted.
