[0024] See also Figures 1 to 4 The utility model provides a technical solution: a steel pipe straightening device based on a scaffold for building construction, comprising: an operating panel 1, four sides of the lower end of the operating panel 1 are fixedly installed with supporting legs 2, one side of the upper end of the operating panel 1 is fixedly installed with a supporting plate 4, the upper end of the supporting plate 4 is lifted and lowered with a pressing plate 7, the supporting plate 4 is L-shaped, one end of the supporting plate 4 is fixedly installed on the upper end of the operating panel 1, and the other end is fixedly installed with a threaded barrel 5, the threaded barrel 5 passes through the upper end side wall of the supporting plate 4, the threaded barrel 5 is internally threaded with a threaded rod 6, the lower end of the threaded rod 6 is rotatably connected to the center of the upper end side wall of the pressing plate 7, and the pressing plate 7 can be driven to move up and down at the inner end of the supporting plate 4 by rotating the threaded rod 6, so as to press the steel pipe placed on the inner side of the supporting plate 4 and limit the position.

[0025] A side plate 3 is provided at the inner end of the support plate 4, and the lower end of the side plate 3 is fixedly mounted on the upper end of the operating plate 1. One end of the side plate 3 contacts the inner wall of one end of the support plate 4, and the other end of the side plate 3 is slidably connected to the side wall of the pressing plate 7. When the pressing plate 7 moves down or up, the pressing plate 7 slides on the side plate 3, thereby preventing the pressing plate 7 from rotating synchronously with the threaded rod 6.

[0026] A force-bearing plate 8 is fixedly installed on the upper end of the operating panel 1, and a hydraulic cylinder 9 is fixedly installed on the front and rear sides of one end of the force-bearing plate 8. The output end of the hydraulic cylinder 9 is fixedly connected to one end of a push plate 10, and the lower end of the push plate 10 is in sliding contact with the upper end of the operating panel 1. The height of the push plate 10 is slightly lower than the diameter of the steel pipe that needs to be corrected. When the hydraulic cylinder 9 is started, the push plate 10 can be driven to move, and the push plate 10 pushes and corrects the steel pipe fixed on one side of the side plate 3.

[0027] A strip rod 11 is provided at one end of the operating panel 1, a slide groove 12 is provided at the upper end of the strip rod 11, and the slide groove 12 is convex. A tooth plate 13 is fixedly installed on the inner wall of the bottom end of the slide groove 12, and a vertical rod 18 is slidably provided in the slide groove 12. A limit plate 19 is provided at the upper end of the vertical rod 18, and a tooth plate 2 14 is fixedly installed at the lower end of the vertical rod 18. A movable plate 16 is provided at the front and rear sides of the upper end of the tooth plate 2 14, and a spring 15 is fixedly installed at the lower end of the movable plate 16.

When the spring 15 is in a balanced state, the tooth plate 13 and the tooth plate 2 14 are engaged with each other to fix the vertical rod 18 and the limit plate 19. The limit plate 19 is used to limit the steel pipe that needs to be corrected. The limit plate 19 can be adjusted according to the position of the steel pipe that needs to be corrected, so that the position that needs to be corrected is located on the inner side of the support plate 4;

[0028] When the position of the limit plate 19 needs to be adjusted, the vertical rod 18 is pulled upward, and the tooth plate 2 14 moves upward by squeezing the spring 15, so that the tooth plate 2 14 and the tooth plate 1 13 are separated, and the limit plate 19 can be moved. After moving to the appropriate position, the vertical rod 18 is released, and under the reaction force of the spring 15 and the gravity of the limit plate 19 and the vertical rod 18, the tooth plate 2 14 moves downward and bites with the tooth plate 1 13, thereby fixing the limit plate 19, which facilitates the movement and fixation of the limit plate 19.

[0029] When the device is working, the length of the steel pipe position is corrected as needed, the position of the limit plate 19 is adjusted, and then the steel pipe passes through the support plate 4 and allows one side to contact the side plate 3 and one end to contact the limit plate 19, and then the threaded rod 6 is rotated to drive the pressure plate 7 to contact the upper end of the steel pipe, thereby fixing the steel pipe, and then the hydraulic cylinder 9 is started to drive the push plate 10 to move and push the steel pipe, thereby completing the correction of the steel pipe.
