[0029] The following will combine with the embodiments of the present utility model to clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work belong to the scope of protection of the present utility model.

[0030] Please refer to Figures 1-5 , the above technical solutions will be described in detail by the following embodiments of the present utility model:

[0031] A steel pipe welding alignment and height adjustment device includes two lifting platforms 3, and further includes:

[0032] A base 1 is provided with a lifting installation groove 111 for installing the lifting platform 3;

[0033] A lifting component 2, referring to the structure shown in Figures 3-5 , includes a support block 21 that can be installed and lifted above the base 1. The support block 21 is provided with a support groove 211 for supporting the steel pipe 8. In this embodiment, the support groove 211 is provided with rubber bumps 25 for protecting the pipe body. On both sides of the support block 21, there are side top plates 22 corresponding to the positions of the lifting platforms 3;

[0034] At the position above the support groove 211 of the lifting component 2, there is a fixed steel cable 5 for clamping the steel pipe 8.

[0035] Referring to the structure shown in Figure 4 , the base 1 includes a connecting plate 12 and L-shaped side blocks 11 symmetrically installed on both sides of the connecting plate 12. The lifting installation groove 111 is provided on the L-shaped side blocks 11; below the connecting plate 12 of the base 1, there is a bottom cavity 101. Inside the bottom cavity 101, a pressing plate 4 is installed through a cylinder 7. The bottom surface of the pressing plate 4 is provided with anti-slip protrusions 41, which can drive the pressing plate 4 to be pressed tightly on the ground through the downward pressure of the cylinder 7 to play an anti-slip positioning role.
