[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] like Figure 1-4 As shown, a wind turbine tower door frame rolling device includes a base plate 1, a hydraulic jack 2, a pressure roller 3, and a column 4; a hydraulic jack 2 is fixedly provided on one side of the top surface of the base plate 1, the fixed end of the hydraulic jack 2 is fixedly connected to the base plate 1, the telescopic end of the hydraulic jack 2 is fixedly connected to the pressure roller 3, and the fixed end of the hydraulic jack 2 is fixedly connected to a first fixed plate 5 on the side away from the pressure roller 3. The first fixed plate 5 is further fixedly connected to the top surface of the base plate 1 on the side away from the pressure roller 3 by multiple first reinforcing plates 6 to improve the stability of the rolling;

[0016] Two columns 4 are fixed on the other side of the top surface of the base plate 1. The two columns 4 are symmetrically arranged on both sides of the pressure roller 3 along the extension and contraction direction of the hydraulic jack 2. A second fixed plate 7 is provided on the side of the two columns 4 away from the pressure roller 3. The second fixed plate 7 is fixedly connected to the base plate 1. The side of the second fixed plate 7 away from the column 4 is also fixedly connected to the top surface of the base plate 1 through multiple second reinforcing plates 8. The second fixed plate 7 is fixedly connected to a support plate 9 in the middle and upper part of the side close to the column 4. Each support plate 9 is arranged parallel to the base plate 1.

[0017] Working principle:

[0018] The steel plate 12 is placed on the bottom plate 1, and the bottom plate 1 and the auxiliary platforms 11 on both sides can ensure that the door frame joints of the steel plate 12 are flush. The area to be rolled on one side of the steel plate 12 is placed between the column 4 and the pressure roller 3, and a magnetic pad 10 is placed between the pressure roller 3 and the steel plate 12. The pad 10 creates a gap between the pressure roller 3 and the steel plate 12 for placing the inspection sample ruler, and the hydraulic jack 2 is turned on to drive the pressure roller 3 to squeeze the steel plate 12 toward between the two columns 4. During the process, the deformation of the steel plate 12 is measured by the inspection sample ruler. When the steel plate 12 is bent to the required curvature, the hydraulic jack 2 contracts, the pad 10 is pulled out, the position of the steel plate 12 is adjusted, and the above steps are repeated until the rolling of all the areas to be rolled on one side of the steel plate 12 is completed. Similarly, the above steps are repeated to roll the area to be rolled on the other side of the steel plate 12. After completing the rolling of the areas to be rolled on both sides of the steel plate 12, the rolling of the area to be rolled in the middle of the steel plate 12 is carried out, thereby completing the rolling of the entire area to be rolled.

[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
