DETAILED DESCRIPTION

[0018] Please refer to Figures 1-4 The utility model provides a kind of auxiliary positioning device for steel pipe construction in water diversion engineering, including positioning plate 1, first auxiliary positioning roller 9 is fixedly installed in the right upper side of positioning plate 1, and second auxiliary positioning roller 10 is fixedly installed in the left upper side of positioning plate 1, while the surface of first auxiliary positioning roller 9 and second auxiliary positioning roller 10 is covered with steel pipe body 11, the bottom of positioning plate 1 is covered with stabilizing seat 2, and two groups of stud 3 are fixedly installed in the bottom of stabilizing seat 2, while mounting cylinder 4 is installed below stud 3, and universal wheel mounting piece 5 is welded and fixed in the bottom of mounting cylinder 4.

[0019] Working principle: when using, first place the device in the diversion channel, when the steel pipe body 11 with large mass is placed in the inside of the channel, the bottom can be supported by multiple devices, the bottom of the steel pipe body 11 is supported by the supporting rollers 93 on the first auxiliary positioning roller 9 and the second auxiliary positioning roller 10, and the two groups of supporting rollers 93 are arranged in a "V" shape, which facilitates the transverse pipe movement of the steel pipe body 11 in the diversion channel; four groups of adjusting columns 7 pass through four groups of notches 6 and are screwed and fixed by nuts 8, the position of the adjusting column 7 inserted in the notch 6 is adjusted horizontally to fine-tune the position of the positioning plate 1 on the surface of the stabilizing seat 2; it is convenient to accurately butt joint the adjacent two groups of steel pipe bodies 11, and it is convenient to weld and fix the connection position between the adjacent two groups of steel pipe bodies 11; without manual pipe alignment welding, a lot of manpower is saved;

[0020] The surface of the two groups of supporting rollers 93 can be wrapped with rubber pads, which are not shown in the figure. When the steel pipe body 11 is transported, the rubber pad is soft and will not damage the corrosion-resistant coating on the circumferential outer wall of the steel pipe body 11. At the same time, the arrangement of the two groups of supporting rollers 93 can avoid direct contact with the bottom or side wall of the trench when the steel pipe is dragged in the trench, which is easy to cause wear due to friction. The corrosion-resistant coating on the surface of the steel pipe is scratched. Once the corrosion-resistant coating is damaged, the steel pipe is easily corroded under the action of soil and water, affecting the service life of the pipeline and the water quality;
