The flame spray gun 4043 can move up and down along the Z-axis, realizing that the flame spray gun 4043 can move in two directions parallel to the axis of the steel pipe and the Z-axis to heat different positions of steel pipes with different diameters.

[0025] Refer to Figure 1, guide rails 103 are installed on both sides of the frame 101. Two sliding seats 401 are respectively slidably installed on the corresponding guide rails 103. A belt drive unit is used for driving connection between a pair of idler rollers 102. Adjacent two coaxial idler rollers 102 are connected by a coupling. One of the idler rollers 102 is connected to an external power input through a drive unit. The external power input can adopt a servo motor or a handwheel, which is used to drive the idler roller 102 to drive the steel pipe to turn over.

[0026] Refer to Figure 2 , the traveling assembly 2 further includes a track 201 for guiding the traveling crane 203. A lead screw 202 is rotatably installed on the side of the track 201. A nut sleeve is sleeved on the lead screw 202 in a driving manner. The nut sleeve is fixedly installed on the traveling crane 203. One end of the lead screw 202 is connected to a driving motor 204. By driving the lead screw 202 to rotate through the driving motor 204, the nut sleeve drives the traveling crane 203 to move along the track 201, so as to adjust the positions of the height adjustment assembly 3 and the straightening assembly 5.

[0027] Refer to Figure 2 , the height adjustment assembly 3 further includes a telescopic cylinder 301 installed between the traveling crane 203 and the bracket 302.

[0028] Refer to Figure 1 , the sliding seat 401 is hinged with a connecting seat, and one end of its hinge shaft is connected to a rotary hydraulic cylinder 405. A plurality of pressure rollers 403 are rotatably installed on the connecting seat, and the pressure rollers 403 located on both sides of the steel pipe are arranged in a staggered manner. By driving the connecting seat to rotate through the rotary hydraulic cylinder 405, the pressure rollers 403 rotate to squeeze and limit the steel pipe.

A gantry 4041 is further installed on the sliding seat 401. A telescopic cylinder 4042 is installed at the lower end of the gantry 4041. The push rod 402 is used to make the sliding seat 401 and the traveling crane 203 move synchronously, so that the pressure rollers 403, the flame spray gun 4043 and the straightening assembly 5 are always synchronous;

[0030] Refer to Figure 3, the correction assembly 5 includes a support column 501 installed on the connecting rod 303. A guiding groove is formed in the support column 501. A slider 504 is slidably installed in the guiding groove. One side of the slider 504 is provided with a telescopic hydraulic cylinder 502. The slider 504 is hinged to four scissor-type pressing units 503. A guiding rod 5032 is installed at the lower end of the pressing plate 5031. A moving block 5033 is slidably installed on the guiding rod 5032. A scissor frame 5034 is installed between the pressing plate 5031 and the support column 501. One side of the scissor frame 5034 is respectively hinged to the pressing plate 5031 and the support column 501. One side of the scissor frame 5034 is respectively hinged to the slider 504 and the moving block 5033. By driving the slider 504 to move through the telescopic hydraulic cylinder 502, the scissor frame 5034 is driven to unfold and fold, and the position of the pressing plate 5031 relative to the support column 501 is adjusted, so as to realize the extrusion correction of steel pipes with different diameters.

[0031] The implementation principle of a correction device for steel structure processing in an embodiment of the present application is as follows:

[0032] Place the steel pipe to be corrected on the bracket assembly 1 and fix it by two idler rollers 102.

[0033] According to the diameter of the steel pipe, the telescopic cylinder 301 adjusts the height of the connecting rod 303 and the correction assembly 5 connected to its end, so that it is aligned with the center of the steel pipe. By driving the screw rod 202 to rotate through the driving motor 204, the traveling crane 203 moves along the track 201 to adjust the position of the correction assembly 5 in the length direction of the steel pipe.

[0034] The heating unit 404 in the auxiliary positioning assembly 4 is started. Specifically, the flame spray gun 4043 moves along the Z-axis and the axis direction of the steel pipe through the telescopic cylinder 4042 to heat different positions of the steel pipe to soften the material for easy correction. The rotating hydraulic cylinder 405 drives the pressure roller 403 to extrude and limit the steel pipe to increase the stability during the correction process. Control the telescopic hydraulic cylinder 502 to drive the slider 504 to move in the guiding groove, drive the scissor-type pressing unit 503 to unfold or fold, so as to perform extrusion correction on the steel pipe through the pressing plate 5031.

[0035] If it is necessary to correct different positions of the steel pipe, the transmission unit in the bracket assembly 1 can be started, and the steel pipe is driven to flip by the idler rollers 102 connected by belt transmission or coupling.
