[0021] Specifically, the first telescopic member 402 may be a telescopic oil cylinder, a hydraulic cylinder, an electric cylinder, and a jack.

[0022] Compared with the prior art, the steel column docking correction device provided in this embodiment has the following advantages: The connecting seat 301 is put on the lower steel column 20, and then the connecting seat 301 is fixed to the outer wall of the lower steel column 20. The position change platform is rotated around the lower steel column 20 by the driving component to adjust the position of the pushing unit 40, thereby adjusting the first telescopic member 402 to any of the four positions of the front, back, left and right of the lower steel column 20. There is no need to fix and disassemble the connecting seat 301 multiple times, which saves correction time and improves correction efficiency.

[0023] In some embodiments, see Figure 1 and Figure 2A plurality of connection units 60 are provided between the connection seat 301 and the lower steel column 20, and the plurality of connection units 60 are arranged around the outer periphery of the lower steel column 20; the connection unit 60 includes a first lead screw 601, a threaded sleeve 602 and a connection strip 603, the first lead screw 601 is slidably connected to the connection seat 301 along the radial direction of the connection seat 301; the threaded sleeve 602 is threadedly connected to the first lead screw 601, and the threaded sleeve 602 is rotatably connected to the connection seat 301 around its own central axis; the connection strip 603 is fixedly arranged at the end of the first telescopic member 402 close to the lower steel column 20, and the connection strip 603 is detachably fixedly connected to the outer wall of the lower steel column 20.

[0024] Specifically, the inner wall of the connecting seat 301 is provided with a sliding cavity 3011 for sliding the first screw 601, the inner wall of the sliding cavity 3011 is fixed with a limit block 3012, the outer wall of the first screw 601 is provided with a limit groove 6011 slidably adapted to the limit block 3012, and the limit groove 6011 extends along the length direction of the first screw 601.

[0025] The staff rotates the threaded sleeve 602, and the threaded sleeve 602 rotates to drive the first screw 601 to move closer to the lower steel column 20 until the connecting bar 603 is pressed against the outer wall of the lower steel column 20, and then the connecting bar 603 is fixed to the outer wall of the lower steel column 20 by welding. After the calibration is completed, the weld between the connecting bar 603 and the lower steel column 20 is cut, thereby separating the connecting bar 603 from the lower steel column 20, and then the staff reverses the threaded sleeve 602 so that the first screw 601 drives the connecting bar 603 away from the lower steel column 20.

[0026] The position of the connecting strip 603 can be moved so as to adapt to steel columns of different lengths and widths, thereby improving the application range of the correction device.

[0027] In some embodiments, see Figure 1 and Figure 2 The end of the first lead screw 601 close to the lower steel column 20 is fixed with an adsorption portion 70; when the connecting strip 603 abuts against the outer wall of the lower steel column 20, the adsorption portion 70 abuts against the outer wall of the lower steel column 20 and is adsorbed and fixed.

[0028] It should be noted that the adsorption portion 70 is a vacuum electric suction cup, and the suction force of the vacuum electric suction cup can fix the correction device on the outer wall of the lower steel column 20.

[0029] Before welding the connecting strip 603 and the lower steel column 20 , the correction device is fixed as a whole to the outer wall of the lower steel column 20 through the adsorption part 70 , thereby facilitating the welding of the connecting strip 603 and the lower steel column 20 .

[0032] In some embodiments, see Figure 1 , Figure 3 and Figure 5 The transposition platform includes a rotating seat 302, a base 303 and a slide 304. The rotating seat 302 is arranged at intervals on the outer periphery of the lower steel column 20. The rotating seat 302 is rotatably connected to the connecting seat 301 around its own central axis. The base 303 is fixed on the top surface of the rotating seat 302. The top surface of the base 303 is provided with a slide groove 3031 along the radial direction of the rotating seat 302. The slide 304 is slidably adapted in the slide groove 3031, and the support 401 is connected to the slide 304.

[0033] A second lead screw 3032 is rotatably connected in the slide groove 3031. The axial direction of the second lead screw 3032 is parallel to the horizontal direction. The second lead screw 3032 rotates around its own central axis. The second lead screw 3032 passes through the slide seat 304 and the two are threadedly connected. A first motor 3033 is installed in the slide groove 3031 and is transmission-connected to the second lead screw 3032. A guide rod 3034 is fixed in the slide groove 3031. The guide rod 3034 is axially parallel to the second lead screw 3032. The guide rod 3034 passes through the slide seat 304 and the two slide.

[0034] The first motor 3033 is started to drive the second lead screw 3032 to rotate, and the second lead screw 3032 drives the slide 304 to move along the guide rod 3034 in the slide groove 3031, so that the slide 304 drives the push unit 40 to approach the lower steel column 20 or move away from the lower steel column 20.

[0035] The position of the pushing unit 40 can be changed. When installing the correction device, the pushing unit 40 is set away from the lower steel column 20 to reduce interference during the installation process. Before correction, the pushing unit 40 is moved so that the positioning plate fits with the lower steel column 20 to facilitate the first telescopic member 402 to push the upper steel column 10.

[0036] In some embodiments, see Figure 3 A lifting platform 80 is provided above the slide 304 , a third telescopic member 801 is fixedly provided between the lifting platform 80 and the slide 304 , and the length of the third telescopic member 801 is adjustable along the vertical direction; the support 401 is rotatably connected to the lifting platform 80 .

[0037] Specifically, the third telescopic member 801 can be a telescopic oil cylinder, a hydraulic cylinder, and an electric cylinder.

The roller 501 is rotatably connected between the support 401 and the lifting platform 80 . The roller 501 rotates around its own central axis. The second motor 502 is transmission-connected to the roller 501 .

[0040] Specifically, an encoder is installed at the output shaft of the second motor 502 , and the encoder is communicatively connected with the second motor 502 .

[0041] The second motor 502 starts to drive the roller 501 to rotate, so that the support 401 and the first telescopic member 402 rotate synchronously, thereby making the positioning surface of the support 401 parallel to the outer wall of the upper steel column 10 to be pushed, and making the telescopic direction of the first telescopic member 402 perpendicular to the outer wall of the upper steel column 10 to be pushed.

[0042] The encoder monitors the rotation angle of the output shaft of the second motor 502 , thereby accurately controlling the position of the ejection unit 40 .

[0043] In some embodiments, see Figure 1 The driving assembly includes a driving gear 305, a driven gear 306 and a third motor 307. The driving gear 305 rotates around its own central axis and is connected to the top surface of the connecting seat 301; the driven gear 306 is fixed to the outer periphery of the rotating seat 302 and meshes with the driving gear 305; the third motor 307 is fixedly installed on the connecting seat 301 and is transmission-connected to the driving gear 305.
