Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine tower production, and in particular to a steel plate turning device for wind turbine tower production. Background Technology

[0002] In the production process of wind turbine towers, steel plates undergo multiple processing steps, requiring frequent flipping operations to work on different surfaces. Current flipping devices have limitations in adaptability; for steel plates required for towers with significant differences in length and width, stable clamping and precise positioning are often difficult. Furthermore, some flipping mechanisms have a small contact area with the steel plate, potentially increasing the risk of deformation or surface damage during operation. Therefore, it is necessary to design a steel plate flipping device with flexible adjustment capabilities, good adaptability, and a stable flipping process to better meet the actual needs of wind turbine tower production. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a steel plate turning device for wind turbine tower production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A steel plate turning device for wind turbine tower production includes a first plate body. A frame is fixedly connected to one end and the other end of the first plate body. A shaft passes through the two frame bodies, and a first frame is fixedly connected to the shaft. A first sleeve is fixedly connected to one end and the other end of the first frame. Two first sleeves are slidably connected to first sliding rods. Two first sliding rods are fixedly connected to a second frame. Both the first and second frames are C-shaped. Two second sleeves are fixedly connected to one end and the other end of the first plate body. Multiple second sleeves are slidably connected to second sliding rods, and the multiple second sliding rods are respectively fixedly connected to corresponding second plates.

[0006] Preferably, multiple rubber blocks are fixedly connected to one end and the other end of the first plate and to the two second plates. The tops of the multiple rubber blocks are arc-shaped, and some of the rubber blocks are in contact with the first frame and the second frame.

[0007] Preferably, multiple first sleeves, second sleeves, first frames, and second frames are threaded with multiple bolts, some of which are in contact with corresponding first slide bars and second slide bars, and one end of each of the multiple bolts is fixedly connected to a first rubber pad.

[0008] Preferably, both frames are machined with two sliding grooves, and the sliding grooves are arc-shaped and concentric with the shaft. The sliding grooves are slidably connected to sliders, and the sliders are fixedly connected to one end and the other end of the first frame, respectively.

[0009] Preferably, both the first frame and the second frame are fixedly connected to a second rubber pad.

[0010] Preferably, the first plate is fixedly connected to a housing, the housing rotatably passes through a shaft, the shaft is fixedly connected to a worm gear, the housing rotatably passes through a worm, the worm gear and the worm are connected in a transmission connection, one end of the housing is fixedly connected to a motor, and the output end of the motor is fixedly connected to the worm.

[0011] Preferably, the box body is hinged to a door.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Through the cooperation between the first plate, shaft, frame, first frame, first sleeve, first slide rod, second block, second sleeve, second slide rod, second plate, and bolts, the second slide rod of the second plate slides against the second sleeve of the first plate and is fixed by bolts. This allows for flexible adjustment of the distance between the second plate and the first plate, ensuring that when the steel plate is rotated by the first and second frames, portions of the first and second frames can contact the rubber block of the second plate, providing auxiliary support during the flipping process. Simultaneously, the first sleeve of the first frame and the first slide rod of the second frame... The sliding connection of the sliding rod and its fixing with bolts allows for adjustment of the distance between the first and second frames, thus adapting to the placement requirements of steel plates of different sizes within a certain range and improving the adaptability to tower steel plates with large differences in length and width. Furthermore, the method of fixing the first and second frames with multiple sets of bolts respectively in contact with both sides of the steel plate helps to increase the contact area with the steel plate, reduce local stress during local steel plate clamping, and reduce the risk of steel plate deformation or surface damage. This enhances clamping stability and positioning accuracy while better meeting the actual needs of steel plate flipping operations in wind turbine tower production.

[0014] 2. By using a combination of a first plate, a second plate, and rubber blocks, and by fixing multiple rubber blocks to both ends of the first plate and on both second plates, the design allows the rubber blocks on the first and second plates to jointly support the first and second frames when the steel plate contacts either side of the second plate during rotation. The advantages of this design are that the rubber blocks themselves have a certain degree of elasticity, which can buffer the impact force generated during the rotation of the steel plate through deformation, reducing vibration caused by hard contact. This helps to prevent deformation or surface damage to the steel plate due to impact and enhances the stability of the first and second frames during the support process. Simultaneously, the multi-position distribution of rubber blocks increases the support contact area, allowing for more even distribution of support force, further improving the overall stability of the device during the steel plate flipping process, and better adapting to the support requirements of wind turbine tower production for flipping steel plates of different sizes.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figures 1 to 5 A steel plate turning device for wind turbine tower production includes a first plate 1. A frame 3 is fixedly connected to one end and the other end of the first plate 1. A shaft 2 rotatably passes through the two frame 3s, driving a first frame 4 and a second frame 7 to rotate. The shaft 2 is fixedly connected to the first frame 4. A first sleeve 5 is fixedly connected to one end and the other end of the first frame 4. A first sliding rod 6 is slidably connected to both first sleeves 5. The first sliding rod 6 can flexibly extend and retract along the axial direction of the first sleeve 5. The two first sliding rods 6 are fixedly connected to the second frame 7. Both the first frame 4 and the second frame 7 are C-shaped to clamp the steel plate from both sides. Two second sleeves 8 are fixedly connected to one end and the other end of the first plate 1. Multiple second sleeves 8 are slidably connected to second sliding rods 9. The second sliding rods 9 can flexibly extend and retract along the axial direction of the second sleeve 8. Multiple second sliding rods 9 are respectively fixedly connected to corresponding second plates 10. The second plates 10 are arranged parallel to the first plate 1, together forming the auxiliary support structure of the device.

[0023] In this embodiment, multiple rubber blocks 11 are fixedly connected to one and the other ends of the first plate 1 and to both second plates 10. The rubber blocks 11 have a certain elastic deformation capability, and the tops of the multiple rubber blocks 11 are all arc-shaped. This arc-shaped design allows for better contact with the outer walls of the first frame 4 and the second frame 7. During the operation of the device, some rubber blocks 11 will contact the bottom or sides of the first frame 4 and the second frame 7, forming auxiliary support. Multiple first sets 5, second sets 8, first frames 4, and second sets 7... Each frame 7 has multiple bolts 12 threaded through it. Some bolts 12 contact the corresponding first slide rod 6 and second slide rod 9, locking their positions through friction. Each bolt 12 has a first rubber pad 13 fixedly connected to one end. The end of each bolt 12 near the first slide rod 6, second slide rod 9, or steel plate is also secured with a first rubber pad 13 by adhesive. The first rubber pad 13 prevents direct hard contact between the bolt 12 and the first slide rod 6, second slide rod 9, or steel plate, thus avoiding wear. Both frame bodies 3 have two sliding grooves 14, and multiple sliding grooves... All 14 are arc-shaped and concentric with the shaft 2, ensuring that the rotation trajectory of the slide groove 14 is consistent with that of the shaft 2. Multiple slide grooves 14 are slidably connected to sliders 15, which are respectively fixedly connected to one end and the other end of the first frame 4. When the first frame 4 rotates, the sliders 15 can slide synchronously along the slide grooves 14, enhancing the rotational stability of the first frame 4. Both the first frame 4 and the second frame 7 are fixedly connected to second rubber pads 16. The surface of the second rubber pads 16 has anti-slip textures, which can protect the steel plate surface from scratches and increase clamping friction. The first plate 1 is fixedly connected to... The housing 18 is rotatably connected to the shaft 2. The shaft 2 is fixedly connected to a worm gear 21. The housing 18 is rotatably connected to a worm 20. The worm gear 21 and the worm 20 are connected by a transmission mechanism with speed reduction and torque increase and self-locking functions, which can ensure that the steel plate can be stably stopped after being flipped to any angle. One end of the housing 18 is fixedly connected to a motor 19. The model of the motor 19 is selected according to the actual working requirements. The output end of the motor 19 is fixedly connected to the worm 20. The housing 18 is hinged to a door 17, which facilitates the operator to inspect and maintain the worm gear 21 and the worm 20 inside the housing 18.

[0024] The working principle of this embodiment is as follows: In use, the first set 5 of the first frame 4 is slidably connected to the first slide rod 6 of the second frame 7 and fixed with bolts 12. After adjusting the distance between the two frames according to the size of the steel plate, the steel plate is placed between the two frames and fixed to both sides of the steel plate by multiple sets of bolts 12 of the first frame 4 and the second frame 7. When flipping, the motor 19 is connected to an external power supply and control device to run. The motor 19 can drive the shaft 2 to rotate the first frame 4, the second frame 7 and the steel plate by the transmission of the worm gear 21 and the worm 20. During the process, a part of the second frame 7 contacts the rubber block 11 of the second plate 10 to obtain auxiliary support. The multiple rubber blocks 11 at both ends of the first plate 1 and on the two second plates 10 jointly support the first frame 4 and the second frame 7 when the steel plate contacts the second plate 10 on either side. The rubber block 11 elastically buffers the impact force to achieve stable flipping and meet the production requirements of wind turbine towers.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
