[0002] In the manufacturing process of wind turbine towers, the rolling of steel plates is a very important process. The quality of this process directly affects the subsequent longitudinal seam welding process and circumferential seam welding process.

[0003] In the current wind turbine tower manufacturing process, the steel plate rolling requires an error variable h≤0.1t (t is the steel plate thickness), and the maximum is 2mm. Under the requirement of refined control of wind turbine towers, this requirement is more stringent. The maximum error variable of the steel plate after rolling is no more than 1mm. In order to meet this requirement, a wind turbine tower steel plate rolling error variable correction device was invented. Utility Model Content

Under the requirement of refined control of wind turbine towers, this requirement is more stringent, and the maximum misalignment of the steel plate after rolling does not exceed 1mm.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a device for correcting the misalignment of rolled steel plates for wind power towers, comprising a rotating rod, an adjusting screw being connected to the bottom of the rotating rod, and a clamping device being fixedly connected to the other end of the adjusting screw, an outer sleeve of the adjusting screw being provided with an outer fixing plate, and a fixing nut being provided at the top of the outer fixing plate, an inner fixing plate being provided at the inner bottom of the outer fixing plate, and a pad being distributed above the inner fixing plate, a rubber pad being provided at the top of the pad, and an auxiliary structure being provided at the bottom of the pad.

[0006] As a preferred technical solution of the utility model, the auxiliary structure includes a buffer rod, a limit block, a buffer spring and a damper. The buffer rod is fixedly installed at the bottom of the pad, and the other end of the buffer rod is fixedly connected to the limit block. The outer surface of the buffer rod is sleeved with a buffer spring, and the damper is fixedly installed in the middle of the bottom end of the pad.

[0009] As a preferred technical solution of the utility model, the pad and the inner fixing plate are distributed in parallel, and the buffer rod and the pad are distributed in a vertical shape.

[0010] As a preferred technical solution of the utility model, the buffer rods are symmetrically distributed along the vertical center line of the pad, and the buffer rods penetrate the inner fixing plate and extend below the inner fixing plate.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0012] 1. The combined use of the rotating rod, adjusting screw, clamping device and fixed plate can facilitate the subsequent correction of the steel plate rolling joint according to actual use requirements, that is, through the rotation of the rotating rod, the adjusting screw is driven to rotate, and the inner and outer fixed plates are brought closer, so as to correct the misalignment of the steel plate rolling joint;

[0013] 2. The combined use of the set pad, buffer rod, limit block and buffer spring can facilitate the subsequent clamping of the steel plate rolling joints to ensure that they can be effectively corrected later. When the pad moves longitudinally, it will push the buffer rod, causing it to drive the limit block to move accordingly, and then the limit block drives the buffer spring to change, and the damper also deforms accordingly. The reverse force generated by the deformation of the two can better clamp the steel plate rolling joints. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0020] Example

[0021] Please refer to Figure 1 As shown, the utility model provides a wind power tower steel plate rolling joint misalignment correction device, comprising a rotating rod 1, an adjusting screw 2 is connected to the bottom of the rotating rod 1, and the other end of the adjusting screw 2 is fixedly connected to a clamping device 3, an outer side of the adjusting screw 2 is sleeved with an outer fixing plate 4, and a fixing nut 5 is arranged at the top of the outer fixing plate 4, an inner fixing plate 6 is arranged at the inner bottom of the outer fixing plate 4, and a pad 7 is distributed above the inner fixing plate 6, a rubber pad 8 is arranged at the top of the pad 7, and an auxiliary structure is arranged at the bottom of the pad 7;

[0022] When in use, the rolled steel plate to be corrected is placed on the inner side of the outer fixing plate 4, and then the longitudinally moving clamping device 3 is used to correct the rolled steel plate.

[0023] As a further implementation of this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an adjusting screw 2 is connected to the bottom of the rotating rod 1, and the other end of the adjusting screw 2 is fixedly connected to a clamping device 3, the rotating rod 1 and the adjusting screw 2 are fixedly connected, and the adjusting screw 2 is fixedly connected to an outer fixing plate 4, an outer sleeve of the adjusting screw 2 is provided with an outer fixing plate 4, and a fixing nut 5 is provided at the top of the outer fixing plate 4, a threaded connection is formed between the fixing nut 5 and the adjusting screw 2, an inner fixing plate 6 is provided at the inner bottom of the outer fixing plate 4, and a pad 7 is distributed above the inner fixing plate 6, the pad 7 and the inner fixing plate 6 are parallel, and the buffer rod 9 and the pad 7 are vertically distributed, and the pad 7 A rubber pad 8 is arranged at the top of the pad 7, and an auxiliary structure is arranged at the bottom of the pad 7, the auxiliary structure includes a buffer rod 9, a limit block 10, a buffer spring 11 and a damper 12, the buffer rod 9 is fixedly installed at the bottom of the pad 7, and the other end of the buffer rod 9 is fixedly connected to the limit block 10, the buffer rod 9 is symmetrically distributed along the vertical center line of the pad 7, and the buffer rod 9 passes through the inner fixing plate 6 and extends below the inner fixing plate 6, the outer surface of the buffer rod 9 is sleeved with a buffer spring 11, the two ends of the buffer spring 11 are respectively fixedly connected to the bottom of the inner fixing plate 6 and the top of the limit block 10, and the damper 12 is fixedly installed in the middle of the bottom end of the pad 7;

[0024] When the rolled steel plate is placed on the inner side of the outer fixing plate 4, the adjusting screw 2 is driven to rotate by rotating the rotating rod 1. Since the adjusting screw 2 is threadedly connected to the outer fixing plate 4 through the fixing nut 5, when the adjusting screw 2 is rotated, the longitudinal movement of the clamping device 3 is realized, so that it contacts the steel plate. At the same time, the outer fixing plate 4 will gradually approach the outer side of the steel plate until it is completely attached to the outer surface of the steel plate. Then, the rotating rod 1 is continued to be rotated, and the force between the outer fixing plate 4 and the inner fixing plate 6 will become larger and larger. If there is a misalignment between the two pairs of steel plates, the misalignment will be corrected under the action of the force until the misalignment between the two pairs of steel plates is completely corrected. After positioning welding, the rotating rod 1 is rotated in the opposite direction to reset the clamping device 3, thereby completing the correction of the misalignment of the steel plate rolling. When the steel plate contacts the inner fixed plate 6, the pad 7 will press down the damper 12 and the buffer rod 9 fixedly connected to its bottom, and the damper 12 will deform accordingly to generate a reverse force. At the same time, the buffer rod 9 will drive the limit block 10 to move, and then the limit block 10 drives the buffer spring 11 fixedly connected to its bottom to deform accordingly. Combined with the reverse force generated by its deformation and the deformation of the damper 12, the pad 7 can better contact with the steel plate, and the provided rubber pad 8 can increase the friction between the two.
