Description

Technical Field

[0001] This utility model relates to the technical field of power transmission tower production and processing equipment, and in particular to a power transmission tower production and processing device. Background Technology

[0002] In the production of power transmission towers, plate rolling machines are mainly used to process flat steel plates into components with a certain curvature. The purpose of this processing is to manufacture curved or cylindrical components that meet the structural design requirements of the transmission tower.

[0003] Plate rolling machines can effectively change the shape of steel plates. For example, certain foundation parts or supporting structures of a steel tower may require curved steel plates to enhance structural stability and load-bearing capacity. Through the processing of a plate rolling machine, steel plates can be rolled into suitable curvatures, thereby better conforming to the design shape and meeting the overall mechanical performance requirements of the steel tower. Secondly, the curved components processed by the plate rolling machine can improve the tightness of the connections between various parts of the steel tower. These curved components can be spliced ​​more naturally with other straight angle steel or steel plates, making the overall structure of the steel tower more stable, reducing stress concentration, and improving the tower's resistance to collapse under various environmental conditions (such as strong winds, ice, and snow).

[0004] Existing plate rolling machines exhibit low stability during the top reel's downward pressure process. This is primarily because the top reel requires significant pressure to bend and deform the steel plate. However, due to the steel plate's inherent elasticity and uneven stress during processing, the top reel experiences a reaction force, causing it to wobble. This wobble affects rolling accuracy, resulting in a rolled steel plate with a curvature that does not meet design requirements, leading to inconsistent curvature in certain areas. Furthermore, poor stability can accelerate wear and tear on the equipment, reducing the plate rolling machine's lifespan. Moreover, low stability can pose safety hazards; for example, a sudden reel shift during rolling could cause the steel plate to slip, injuring operators. Utility Model Content

[0005] In view of this, the technical problem to be solved by this utility model is: how to provide a power tower production and processing device to improve the working stability of the top reel when pressing down on the reel plate.

[0006] To achieve the above objectives, this utility model proposes a power transmission tower production and processing device, which includes a frame, a first reel, a second reel, a third reel, a first mounting base, a second mounting base, and a third mounting base;

[0009] The first mounting base is connected to the frame by connecting bolts. The connecting bolts are arranged vertically and are respectively provided with a first nut, a second nut, a first compression spring, and a second compression spring. The end of the connecting bolt passes through the first mounting base and through a through hole on the top of the frame. The first nut is connected to the end of the connecting bolt.

[0012] Furthermore, the outer diameter of the first reel is larger than the outer diameter of the second reel and the outer diameter of the third reel.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] Please see Figure 1-3 As shown, this utility model proposes a power transmission tower production and processing device, which includes a frame 10, a first reel 21, a second reel 22, a third reel 23, a first mounting base 11, a second mounting base 12, and a third mounting base 13.

[0019] The first mounting base 11 is disposed at both ends of the frame 10, and the two ends of the first reel 21 are rotatably connected to the first mounting base 11 respectively. The second mounting base 12 is disposed at both ends of the frame 10, and the two ends of the second reel 22 are rotatably connected to the second mounting base 12 respectively. The third mounting base 13 is disposed at both ends of the frame 10, and the two ends of the third reel 23 are rotatably connected to the third mounting base 13 respectively.

[0020] The axis of the first scroll 21 is parallel to the axis of the second scroll 22, the axis of the second scroll 22 is parallel to the axis of the third scroll 23, the second scroll 22 and the third scroll 23 are arranged side by side, and the first scroll 21 is located above the second scroll 22 and the third scroll 23.

[0021] The outer diameter of the first spool 21 is larger than that of the second spool 22 and the third spool 23. Drive sprockets 24 are respectively installed at the ends of the second spool 22 and the third spool 23, and these drive sprockets 24 are used to connect the chain.

[0022] With the three reels arranged in a specific layout, the first reel 21, positioned above the two parallel reels below (the second reel 22 and the third reel 23) and having a larger outer diameter, effectively applies pressure to the steel plate, causing it to bend and deform, thus achieving the function of rolling the steel plate into the required arc. During the rolling process, the reasonable arrangement and dimensional design of each reel ensures that the steel plate is subjected to relatively uniform stress, thereby guaranteeing the rolling accuracy and ensuring that the rolled arc steel plate meets the requirements for arc consistency and accuracy in the production of power transmission towers. This is beneficial to improving the stability and quality of the overall tower structure.

[0023] The first mounting base 11 is connected to the frame 10 by connecting bolts 30. The connecting bolts 30 are arranged vertically and are respectively provided with a first nut 31, a second nut 32, a first compression spring 41, and a second compression spring 42. The end of the connecting bolt 30 passes through the first mounting base 11 and through a through hole on the top of the frame 10. The first nut 31 is connected to the end of the connecting bolt 30. The first compression spring 41 is sleeved on the connecting bolt 30. The top of the first compression spring 41 abuts against the bottom of the first nut 31 and the bottom of the first compression spring 41 abuts against the top of the frame 10. The second nut 32 is located above the first mounting base 11 and below the top of the frame 10. The second compression spring 42 is sleeved on the connecting bolt 30. The top of the second compression spring 42 abuts against the bottom of the top of the frame 10 and the bottom of the second compression spring 42 abuts against the second nut 32. The stiffness coefficient of the first compression spring 41 is greater than that of the second compression spring 42.

[0024] The second and third reels 22 and 23 are equipped with drive sprockets 24 and connected to chains at their ends. This transmission method ensures good synchronization between the second and third reels 22 and 23 during power transmission. When the device is running, the chain drives the drive sprockets 24 to rotate, thereby enabling the second and third reels 22 and 23 to work together. This avoids problems such as twisting and jamming of the steel plate during the rolling process caused by asynchronous rotation of the two reels, ensuring smooth rolling operations, improving production efficiency, and reducing scrap rates.

[0025] The first reel 21 is used to perform pressing and rolling processing on the coil plate. The first reel 21 is connected to the frame 10 through the first mounting base 11. In order to improve the connection stability of the first mounting base 11 and ensure that the first reel 21 connected to it can be stably pressed onto the surface of the coil plate, a first compression spring 41 and a second compression spring 42 are respectively provided on the connecting bolt 30 connected to the first mounting base 11. The first nut 31 and the second nut 32 are used to limit the installation position of the first compression spring 41 and the second compression spring 42 on the connecting bolt 30. The first compression spring 41 provides support for the first mounting base 11 in the vertical direction. The second compression spring 42 can stably achieve the vertical position of the first mounting base, thereby stabilizing the pressing stability of the first reel 21 in the vertical direction, thus improving the working stability of the top reel when pressing down on the coil plate.

[0026] The elastic buffer design in the connection between the first mounting base 11 and the frame 10 is ingenious. The first compression spring 41 and the second compression spring 42 on the connecting bolt 30, together with the first nut 31 and the second nut 32, play an important role in the operation of the device. The stiffness coefficient of the first compression spring 41 is greater than that of the second compression spring 42. When the first reel 21 is subjected to a reaction force during the winding process, resulting in a tendency for vertical displacement, the first compression spring 41 can provide greater elastic resistance to suppress large-amplitude swaying and ensure the stability of the first reel 21; while the second compression spring 42 can buffer and absorb smaller-amplitude high-frequency vibrations. The synergistic effect of the two reduces the problem of reduced winding accuracy caused by reel swaying, reduces wear caused by vibration, extends the service life of the equipment, and enhances the overall stability of the device during winding operations, reduces safety hazards, provides a safer and more reliable working environment for operators, and promotes the smooth and efficient operation of the power tower production and processing process.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
