Description

Technical Field

[0001] This utility model relates to the field of metal sheet processing technology, specifically to a wind turbine tower rolling machine with an automatic sheet centering device. Background Technology

[0002] A wind turbine tower rolling machine is a super-powerful and precise industrial device specifically designed to roll large, thick, and hard steel plates into conical cylinders like those used in large wind turbine columns. Like a pair of giant metal hands with precise control, it kneads flat plates into precise curved cylinders and is an indispensable core piece of equipment in the manufacture of wind turbine towers.

[0003] Current wind turbine tower plate rolling machines require centering and adjustment of the material plates during use. In the current production process, manual centering is usually required by workers. Due to the weight of the steel itself, this is time-consuming and inefficient. Therefore, the inventor urgently needs to invent a mechanical device that can achieve automatic centering. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a wind turbine tower rolling machine with an automatic plate centering device to solve the technical problem of inconvenient plate processing centering.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind turbine tower plate rolling machine with an automatic plate centering device, comprising a fixed rod and a rolling device. A telescopic rod is movably connected to the upper side of the fixed rod, and the telescopic rods are connected to each other by a connecting rod. A sliding groove is provided on the surface of the connecting rod. A left support plate and a right support plate are provided on the right side of the fixed rod. A motor is installed on the inner side of the right support plate. Rollers are rotatably connected to the inner walls of the left support plate and the right support plate. The rolling device includes a first rolling wheel, a second rolling wheel, and a third rolling wheel.

[0006] By adopting the above technical solution, a stable main frame is constructed through the linkage design of fixed rods and telescopic rods, which ensures the structural rigidity and vibration resistance of the equipment when bearing large wind turbine tower plates, providing a solid foundation for high-precision rolling. The sliding groove on the surface of the connecting rod and the sliding cooperation of the left and right support plates form a physical guiding constraint, ensuring the linear motion accuracy of the plate during the centering process and avoiding the deflection error that is easy to be generated by traditional hydraulic push plate.

[0007] Furthermore, the first reel, the second reel, and the third reel form a feed inlet through height adjustment, and the feed inlet is used to limit the angle at which the material plate enters.

[0008] By adopting the above technical solution, the adjustable height difference between the first, second and third rollers forms a dynamic feed inlet, which can flexibly adjust the inlet angle according to different plate thicknesses and curvature requirements, and achieve precise control of the initial bending angle of the plate. This structure can pre-set the bending trajectory of the plate and reduce the problem of ellipticity caused by angle deviation.

[0009] Furthermore, the connecting rod can move up and down by adjusting the telescopic rod to ensure that the connecting rod and the feed inlet remain on the same plane.

[0010] By adopting the above technical solution, the telescopic rod drives the connecting rod to achieve Z-axis lifting and lowering, so that the chute and the feed port always remain coplanar, which solves the problem of uneven bending force caused by the difference in feeding height of plates of different thicknesses, and avoids the end deformation of the plate due to suspension.

[0011] Furthermore, there are four sets of both the fixed rod and the telescopic rod, and every two sets of the fixed rod are horizontally arranged.

[0012] By adopting the above technical solution, the distributed layout of four sets of fixed rods and telescopic rods constitutes a spatial truss support system, which significantly enhances the torsional stiffness of the equipment. Every two sets of horizontally symmetrical fixed rods form a double load-bearing defense line, dispersing the radial pressure of hundreds of tons generated during the plate rolling process and avoiding frame deformation caused by local stress concentration.

[0013] Furthermore, the roller is driven by a motor to transport the material plate.

[0014] By adopting the above technical solution, the motor-driven roller is integrated into the inner side of the left and right support plates. During the centering stage, it can actively transport the plate material, transforming the friction force from traditional static friction to dynamic friction, reducing the pushing resistance, and is especially suitable for the precise fine adjustment of high-strength thick plates.

[0015] Furthermore, the surface of the roller is covered with a polyurethane protective layer to protect the material plate during the conveying process.

[0016] By adopting the above technical solution, the polyurethane protective layer on the surface of the roller shaft and the right support plate are fixedly connected to the ground to support the roller shaft.

[0017] By adopting the above technical solution, the rigid connection between the left and right support plates and the ground forms a stable base throughout the entire area, so that the roller shaft has no slight displacement when bearing the load of the plate and the driving torque of the motor, thus eliminating the micron-level reference drift required for high-precision alignment.

[0018] In summary, the present invention has the following main advantages:

[0019] 1. This utility model avoids the errors and time-consuming process of manual adjustment through the linkage design of the slide groove and the telescopic rod. The first, second and third rollers of the plate rolling device form a dynamic feed port through height adjustment, actively controlling the initial bending angle of the plate, reducing curvature deviation during the rolling process, and ensuring the conical accuracy of the wind turbine tower. The connecting rod realizes the lifting and lowering adjustment through the telescopic rod, so that the plane of the slide groove is always coplanar with the feed port, eliminating the interference of the feed height difference of plates of different thicknesses, and finally achieving efficient and high-precision automatic centering.

[0020] 2. This utility model features a roller driven by a motor and covered with a polyurethane protective layer, which reduces conveying friction resistance and prevents scratches on the surface of high-strength sheet metal. The four sets of horizontally symmetrical fixed rods and telescopic rods enhance the overall torsional rigidity. The left and right support plates are fixedly connected to the ground, eliminating micro-displacement of the support structure and ensuring the long-term stability of the centering reference, thus adapting to the manufacturing standards of wind turbine towers.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] In this embodiment:

[0028] A wind turbine tower roll forming machine with an automatic plate centering device, such as Figure 1-4As shown, the device includes a fixed rod 1 and a plate-rolling device 9. A telescopic rod 2 is movably connected to the upper side of the fixed rod 1, and the telescopic rods 2 are connected to each other by a connecting rod 3. A groove 4 is provided on the surface of the connecting rod 3. A left support plate 5 and a right support plate 6 are provided on the right side of the fixed rod 1. A motor 7 is installed on the inner side of the right support plate 6. Rollers 8 are rotatably connected to the inner walls of the left support plate 5 and the right support plate 6. The plate-rolling device 9 includes a first rolling wheel 901, a second rolling wheel 902, and a third rolling wheel 903. A stable main frame is constructed through the linkage design of the fixed rod 1 and the telescopic rod 2. This ensures the structural rigidity and vibration resistance of the equipment when bearing large wind turbine tower plates, providing a solid foundation for high-precision rolling. The sliding groove 4 on the surface of the connecting rod 3 and the sliding cooperation of the left and right support plates 5 and 6 form a physical guiding constraint, ensuring the linear motion accuracy of the plate during the centering process and avoiding the deflection error that is easy to produce by traditional hydraulic plate pushing. The three sets of rolling wheels of the plate device 9 are driven by the motor 7 of the roller shaft 8 to realize the integrated conveying and rolling function, which simplifies the transmission structure and avoids the cumulative error caused by multiple positioning, significantly improving the processing efficiency of ultra-long plates.

[0029] See Figure 1 , Figure 2 , Figure 3 The first reel 901, the second reel 902, and the third reel form a feed inlet 11 through height adjustment. The feed inlet 11 is used to limit the entry angle of the material plate 10. The adjustable height difference between the first reel 901, the second reel 902, and the third reel 903 forms a dynamic feed inlet 11, which can flexibly adjust the inlet angle according to different plate thicknesses and curvature requirements, and achieve precise control of the initial bending angle of the plate. This structure can pre-set the bending trajectory of the plate, reducing the problem of ellipticity caused by angle deviation. The active limiting function of the feed inlet 11 forms a collaborative closed loop with the subsequent rolling process. In the processing of the conical cylinder section of the wind turbine tower, it effectively suppresses the axial movement of the plate during the rolling process and ensures that the longitudinal seam of the cylinder meets the stringent welding requirements.

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The connecting rod 3 moves up and down by adjusting the telescopic rod 2, ensuring that the connecting rod 3 and the feed inlet 11 are on the same plane. The telescopic rod 2 drives the connecting rod 3 to lift and lower, so that the chute 4 and the feed inlet 11 always remain coplanar. This solves the problem of uneven bending stress caused by the difference in feeding height of plates of different thicknesses, and avoids the end deformation of the plate due to suspension. The dynamic compensation during the lifting process is directly achieved through the mechanical structure, without the need for an additional height setting device, which reduces the complexity of the control system and improves the equipment's adaptability to different working conditions.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The fixed rod 1 and the telescopic rod 2 are each set of four, and every two sets of fixed rod 1 are set horizontally. The distributed layout of the four sets of fixed rod 1 and telescopic rod 2 constitutes a spatial truss support system, which significantly enhances the torsional stiffness of the equipment. Every two sets of horizontally symmetrical fixed rod 1 form a double load-bearing defense line, which disperses the radial pressure of hundreds of tons generated during the plate rolling process and avoids frame deformation caused by local stress concentration. This structure provides multi-point guidance for the lateral sliding of the slide 4 and the support plate, ensuring synchronous error of left and right displacement when pushing large-size plates, and eliminating the centering failure caused by frame deformation from the root.

[0032] See Figure 1 , Figure 2 The roller 8 is driven by the motor 7 to convey the material plate 10. The roller 8 driven by the motor 7 is integrated inside the left 5 and the right support plate 6. During the centering stage, it can actively convey the plate and change the friction from the traditional static friction to dynamic friction, reducing the pushing resistance. It is especially suitable for the precise fine adjustment of high-strength thick plates. The conveying power is seamlessly connected with the rolling process. After the plate is centered, it is continuously conveyed to the rolling wheel by the same roller 8, eliminating the positioning offset caused by secondary clamping and ensuring the consistency of the plate position from centering to forming.

[0033] See Figure 1 , Figure 2 , Figure 3 The surface of roller 8 is covered with a polyurethane protective layer to protect the material plate 10 during the conveying process. The polyurethane protective layer on the surface of roller 8 absorbs the micro-unevenness of the plate surface through elastic deformation, preventing the high-strength steel plate from generating scratches or indentations under high pressure, ensuring that the tower surface meets the cleanliness standard. The high coefficient of friction and wear-resistant properties of polyurethane material not only ensure that the thick plate is not slipped during conveying, but also reduce the adhesion of metal debris and extend the maintenance cycle of roller.

[0034] See Figure 1 , Figure 2 The left support plate 5 and the right support plate 6 are fixedly connected to the ground to support the roller shaft 8. The rigid connection between the left and right support plates 5 and 6 and the ground forms a stable base throughout the entire area, so that the roller shaft 8 has no slight displacement when bearing the load of the plate and the driving torque of the motor, eliminating the micron-level reference drift required for high-precision centering. This design directly couples the vibration transmission path of the plate rolling machine with the foundation, avoiding the inaccuracy of laser sensor detection caused by vibration and improving the dynamic stability of the centering system.

[0035] The implementation principle of this embodiment is as follows: the telescopic rod 2 drives the connecting rod 3 to rise and fall, so that the conveying plane of the chute 4 is precisely coplanar with the feed inlet 11 of the plate rolling device 9. The material plate 10 is placed on the rollers 8 of the left support plate 5 and the right support plate 6. The rollers are driven to rotate by the motor 7 to reduce the frictional resistance of the plate movement. The rollers 8 continuously convey the plate until the center line of the material plate 10 coincides with the axis of the first roller 901 and the second roller 902. The material plate 10 enters the rolling area through the feed inlet 11. This inlet is jointly limited by the height difference between the first roller 901 and the second roller 902 and the position of the third roller 903. The third roller 903 applies radial pressure, which, together with the rotation drive of the first roller 901 and the second roller 902, continuously bends the plate into the conical cylindrical section required for the wind turbine tower. The precise alignment of the material plate 10 is achieved through precise coplanarity, and finally, the operation is simplified for the staff.
