[0027] To improve the straightening effect of the device on bent steel pipes, please refer to Figure 1 - Figure 4 In a preferred embodiment, the driving end 21 includes a rotating disk 211, a handle 212 and a first gear 213; the handle 212 is fixed on the rotating disk 211, and the end of the rotating disk 211 facing away from the handle 212 is connected to the first gear 213 through a rotating shaft, the first gear 213 is arranged in the mounting frame 1, and the outer periphery of the first gear 213 is meshed with the transmission end 22, and a plurality of limit rods 14 are arranged between the first frame 11 and the second frame 12, and the transmission end 22 is rotatably connected in the limit rod 14, and the transmission end 22 includes a second gear 221 and a transmission screw 222. The outer periphery of the second gear 221 is meshed with the first gear 213. The second gear 221 is fixed with a transmission screw 222. The transmission screw 222 is rotatably arranged between a plurality of limit rods 14, and the end of the transmission screw 222 is threadedly connected with a push-straight end 23. The push-straight end 23 includes a connecting sleeve 231 and a push block 232. The connecting sleeve 231 is threadedly connected to the end of the transmission screw 222, and the end of the connecting sleeve 231 is fixed with a push block 232.

[0028] The staff drives the rotating disk 211 to operate through the handle 212, and drives the first gear 213 to move through the rotating shaft, wherein the first gear 213 is a circular spur gear with an outer diameter of 100 mm, the second gear 221 is a circular spur gear with an outer diameter of 180 mm, and the rotating disk 211 is a circular steel plate with a thickness of 5 mm and a diameter of 200 mm. When the first gear 213 and the second gear 221 cooperate and drive the second gear 221 to operate, the second gear 221 drives the transmission screw 222 to rotate, and the transmission screw 222 drives the connecting sleeve 231 threadedly connected to its surface to perform horizontal linear motion, and prompts the push block 232 to abut against the bent steel pipe, wherein the push block 232 is a C-shaped top support, which is a No. 6.3 channel steel, and the steel pipe to be straightened is an ordinary steel pipe with a diameter of 48.3 mm.

[0029] To ensure the stability of the straightened steel pipe during processing, please refer to Figure 1 - Figure 4In a preferred embodiment, the straightening mechanism 2 also includes two limit ends 25, any one of the limit ends 25 includes a driving screw 251, a first clamping block 252 and a second clamping block 253; the driving screw 251 is arranged on the outer side of the mounting frame 1, and a first thread groove and a second thread groove are opened on the driving screw 251, and the thread directions of the first thread groove and the second thread groove are opposite, the first thread groove is threadedly connected to the first clamping block 252, and the second thread groove is threadedly connected to the second clamping block 253, and the first clamping block 252 and the second clamping block 253 constitute a clamping area.

[0030] When the steel pipe to be straightened extends to the gap 13 between the first frame 11 and the second frame 12, the two ends will protrude outward. At this time, the staff rotates the driving screw 251 to cause the driving screw 251 to rotate. Since the driving screw 251 is provided with a first thread groove and a second thread groove with opposite thread directions, the first clamping block 252 and the second clamping block 253 can be synchronously driven to move closer to or away from each other. Since the first clamping block 252 and the second clamping block 253 are both semicircular blocks, they can clamp the two ends of the steel pipe to be straightened. This ensures that the steel pipe will not be displaced during the straightening process, thereby further improving the straightening efficiency of the rotating device.

[0031] In order to better understand the present invention, the following Figure 1 - Figure 4 The working process of the bent steel pipe straightening device for construction engineering of the utility model is described in detail: when in use, the staff extends the steel pipe to be straightened into the gap 13 between the first frame 11 and the second frame 12, and adjusts the distance between the two bearing blocks 241 according to actual conditions. After the adjustment is completed, the bolt 242 passes through the bearing block 241 and extends into the positioning hole 111. The staff clamps the two ends of the steel pipe through the first clamping block 252 and the second clamping block 253. After clamping, the handle 212 is used to drive the rotating disk 211 to rotate, and the first gear 213 drives the second gear 221 to operate. When the second gear 221 operates, it simultaneously drives the transmission screw 222 to rotate, and the transmission screw 222 drives the connecting sleeve 231 to move horizontally, and contacts the bent end of the bent steel pipe through the push block 232, and through the cooperation of the connecting sleeve 231 and the push block 232, continuously exerts force on the bent steel pipe, thereby causing the bent part to become straight.
