The downward pressing straightening component 2 includes a first straightening rod 201 and a second straightening rod 202 arranged sequentially from top to bottom. The first straightening rod 201 and the second straightening rod 202 are provided with a horizontal gap for the steel pipe 11 to be straightened to pass through in the horizontal direction.
[0024] The upward straightening component 3 includes a third straightening rod 301 and a fourth straightening rod 302 arranged in sequence from top to bottom. The first straightening rod 201 and the second straightening rod 202 are provided with a horizontal gap for the steel pipe 11 to be straightened to pass through in the horizontal direction; a limit buckle 12 for fixing the steel pipe 11 to be straightened is provided in the middle of both the first straightening rod 201 and the fourth straightening rod 302.
[0025] When using the downward pressing straightening component 2 to straighten the steel pipe 11 to be straightened, the steel pipe 11 to be straightened is inserted between the first straightening rod 201 and the second straightening rod 202. The front section of the steel pipe 11 to be straightened is fixed to the limit buckle 12 below the first straightening rod 201, and the middle section of the steel pipe 11 to be straightened contacts the upper part of the second straightening rod 202; when using the downward pressing straightening component 2 to straighten the steel pipe 11 to be straightened, the steel pipe 11 to be straightened is inserted between the third straightening rod 301 and the fourth straightening rod 302. The front section of the steel pipe 11 to be straightened is fixed to the limit buckle 12 above the fourth straightening rod 302, and the middle section of the steel pipe 11 to be straightened contacts the upper part of the third straightening rod 301.
[0026] Specifically, the limit buckle 12 can be selected as a cross-shaped steel pipe fastener for scaffolding, which is convenient for quickly processing and manufacturing the entire steel pipe straightening device at the construction site.
[0027] In order to adapt to steel pipes 11 to be straightened with different specifications, the horizontal gap between the first straightening rod 201 and the second straightening rod 202 is smaller than the horizontal gap between the third straightening rod 301 and the fourth straightening rod 302. During the process of straightening the steel pipe 11 to be straightened, according to the bending direction and length of the steel pipe 11 to be straightened, the downward pressing straightening component 2 and the upward straightening component 3 are selected, and the limit buckle 12 in the downward pressing straightening component 2 and the upward straightening component 3 is used for fixing. Then, with the help of manpower, it is pressed or lifted in the direction opposite to the bending direction of the steel pipe 11 to be straightened to straighten and repair the steel pipe 11 to be straightened.
[0028] Specifically, the fixed support frame 1 includes two front vertical rods 4 arranged horizontally at intervals. At the bottom of the two front vertical rods 4, two bottom longitudinal rods 5 are arranged horizontally at intervals. At the top of both ends of the two bottom longitudinal rods 5, a bottom cross bar 6 is provided. The front vertical rods 4, the bottom longitudinal rods 5, and the bottom cross bar 6 are perpendicular to each other; the fourth straightening rod 302 and the first straightening rod 201 are horizontally arranged in the middle and upper parts between the two front vertical rods 4 respectively; two rear diagonal braces 7 are inclined between the two front vertical rods 4 and the two bottom longitudinal rods 5. The top ends of the two rear diagonal braces 7 are respectively fixedly connected to both ends of the first straightening rod 201, and the bottom ends of the two rear diagonal braces 7 are respectively fixedly connected to both ends of the bottom cross bar 6 far away from the direction of the front vertical rod 4; the second straightening rod 202 and the third straightening rod 301 are respectively fixed in the middle and upper parts between the two rear diagonal braces 7.
[0029] In the middle of each of the two front vertical rods 4, a middle horizontal rod 8 parallel to the bottom horizontal rod 5 is provided. One end of a single middle horizontal rod 8 is fixedly connected to the corresponding front vertical rod 4, and the other end is fixedly connected to the corresponding rear diagonal brace 7. The setting of the middle horizontal rod 8 is used to strengthen the overall strength between the front vertical rod 4 and the rear diagonal brace 7 and prevent deformation.
[0030] Both ends of each middle horizontal rod 8 are respectively located outside the front vertical rod 4 and the rear diagonal brace 7. Rubber anti-slip sleeves 9 and auxiliary pry pipes 10 are respectively arranged at both ends of each middle horizontal rod 8. The auxiliary pry pipe 10 is detachably connected to the end of the middle horizontal rod 8. The beneficial effect of the above setting is that the entire steel pipe straightening device can be manually transferred by lifting the end of the middle horizontal rod 8; the role of the auxiliary pry pipe 10 is as follows: if the steel pipe 11 to be straightened with a shorter repair length is to be repaired, the head end of the steel pipe 11 to be straightened is inserted into the limit buckle 12 of the straightening device, then the auxiliary pry pipe 10 is sleeved on the tail of the steel pipe 11 to be straightened, and finally the steel pipe 11 to be straightened is straightened by manually pressing it in the reverse direction. The auxiliary pry pipe 10 can be a steel pipe with an inner diameter of 57 mm, and the connection method can be a threaded connection. The auxiliary pry pipe 10 is used in cooperation with the steel pipe straightening device, providing the condition for the manual and rapid repair of short steel pipes and increasing the application range of the steel pipe straightening device.

The role of the front diagonal brace 13 is to strengthen the connection strength between the rear diagonal brace 7 and the front vertical rod 4, increase the structural strength and stiffness of the entire steel pipe straightening device, and prevent problems such as deformation during use.
[0032] When specifically manufacturing the entire steel pipe straightening device, the first straightening rod 201, the second straightening rod 202, the third straightening rod 301, the fourth straightening rod 302, the front vertical rod 4, the bottom horizontal rod 5, the bottom cross bar 6, the rear diagonal brace 7, and the middle horizontal rod 8 are all made of steel pipes with a specification of φ48.3×3.2 mm. The various rod-like components can be detachably connected through scaffolding. It is convenient to replace each component after damage. It not only has a low cost but also has a simple and light overall structure, can be quickly transferred, and is suitable for use under complex conditions.
[0033] In summary, a steel pipe straightening device of the present utility model is applicable to the steel pipe straightening and repair process of construction scaffolding projects. It is simple to manufacture, convenient to use, low in cost, can improve the effective utilization rate of materials, effectively reduce material losses, and has strong applicability.
