[0022] The present utility model provides a technical solution: As Figures 1 - 3 shown, in this embodiment, a pipe laying anti-extrusion climbing device includes a climbing device body 1. The climbing device body 1 is composed of a support cross frame 5 and a support mechanism 2. The support cross frame 5 is welded on both sides of the support mechanism 2. Four support feet 6 are fixedly connected to the bottom of the support mechanism 2. The support mechanism 2 is composed of climbing rods 4 and four support vertical rods 3. The four support vertical rods 3 are respectively fixedly connected to the tops of the four support feet 6. Climbing rods 4 are fixedly connected at equal intervals between the outer sides of the four support vertical rods 3. Processing pipe bodies 8 are arranged on both sides of the support mechanism 2. The outer side of the support cross frame 5 is in contact with the outer side of the processing pipe body 8. An anti-slip and wear-resistant pad 7 is fixedly connected to the bottom of the support foot 6. The support vertical rods 3 and the climbing rods 4 are all connected by electric welding.

[0023] When carrying out the pipe laying and welding work of the processing pipe body 8, first cut a steel pipe with a corresponding length according to the distance between the two processing pipe bodies 8, and assemble and weld according to the device structure, so that the anti-slip and wear-resistant pad 7 on the bottom surface of the support foot 6 is in contact with the ground to improve the stability of the device during use. At the same time, the outer sides of the support cross frame 5 and the support mechanism 2 are in contact with the outer side of the processing pipe body 8, so that during the pipe welding process, by setting a special climbing device body 1, it can effectively prevent phenomena such as the rolling and displacement of the welded pipe from causing personal injuries. The device includes two parts, the support cross frame 5 and the support mechanism 2. The support cross frame 5 and the support mechanism 2 are all made of steel pipes with an outer diameter of 48.3 mm and a wall thickness of 3.5 mm by welding, and have the characteristics of large support stiffness, safety and stability, simple structure, convenient taking and placing, and simple production.
