[0027] The top edge of the sliding connection seat 6 is limitedly slid along the limit groove 3 through the limit clamp 8. A hydraulic cylinder 9 is fixedly installed at the bottom of the sliding connection seat 6, and the telescopic end of the hydraulic cylinder 9 is fixedly connected to the edge of the middle pillar 4. The middle end of the top of the middle pillar 4 is hinged with a middle rotating rod 10. Both ends of the middle rotating rod 10 are hinged with a rotating connecting support rod 11.

[0028] The top end of the limiting clamp block 8 is fixedly connected with an arc-shaped clamp plate 12 , and the inner side end of the arc-shaped clamp plate 12 is bonded with a rubber strip 13 .

[0029] The top of the clamping seat 2 is fixedly installed with mounting plates 14 at both sides of the limiting groove 3, and both sides of the top of the mounting plate 14 are fixedly connected with connecting swivel seats 15, and the inner side of the connecting swivel seat 15 is rotatably connected with an arc-shaped pressing block 16, and the inner side of the arc-shaped pressing block 16 is fixedly bonded with a flexible rubber pad 18;

[0031] Working principle and use process of the utility model: In the actual clamping application process of the hot-dip galvanized steel pipe production adjustable clamping device, firstly, the length of the mounting frame 1 is reasonably determined according to the length of the steel pipe to be clamped, and at the same time, a suitable number of clamping seats 2 are installed according to the length of the steel pipe, and the clamping seats 2 are mainly connected and installed with the mounting frame 1 through the installation ear plate 20;

[0032] After the clamping seat 2 is installed, the steel pipe is placed between the two arc-shaped pressing blocks 16 at the top of the clamping seat 2. During this process, when the steel pipe squeezes the two arc-shaped pressing blocks 16, the bottom of the arc-shaped pressing block 16 will deflect in the connecting seat 17, and the arc-shaped pressing block 16 will squeeze the supporting spring 19 on its side.

When the rotating connection support rod 11 deflects, the middle rotating rod 10 hinged thereto rotates at the top of the middle pillar 4. At the same time, the middle rotating rod 10 is used to drive the rotating connection support rod 11 hinged at the other end to deflect, so that the rotating connection support rod 11 is used to drive another sliding connection seat 6 to move, so that the two sliding connection seats 6 can drive the limiting clamping blocks 8 and the arc clamping plates 12 at their tops to move toward or away from each other;

[0034] When the sliding connection seat 6, the limit clamping block 8 and the arc-shaped clamping plate 12 move relative to each other, the two arc-shaped clamping plates 12 are used to realize the limit clamping treatment of the side wall of the steel pipe, and during the clamping process, the rubber strip 13 further ensures the stability of the arc-shaped clamping plate 12 clamping the steel pipe. In addition, this clamping method utilizes the relative movement of the two arc-shaped clamping plates 12 to realize mobile clamping, which can adaptively clamp steel pipes of different diameters, so as to better meet the clamping needs of the steel pipe.
