Description

Technical Field

[0001] This application relates to the technical field of steel coil turntables, and more particularly to a freely rotatable steel coil turntable. Background Technology

[0002] Steel coils are steel products processed into continuous coils through hot rolling or cold rolling processes, facilitating storage, transportation, and subsequent processing. A steel coil turning table is a mechanical device used to change the direction or angle of steel coils during production, processing, or transportation, and is widely used in industries such as steel, metallurgy, and logistics.

[0003] A steel coil placement platform, disclosed on the Chinese Patent Network (publication number CN218229982U), includes multiple spaced support plates. The support plates are welded and fixed to each other on both sides via connecting rods. An arc-shaped groove is provided on the upper part of each support plate, and two inclined placement plates are symmetrically arranged on both sides of the groove. Arc-shaped rubber protective pads are placed on the two placement plates, and steel coils can be placed on these pads. A protective cover is also provided above the two placement plates. This invention effectively supports and limits the movement of steel coils of different specifications, preventing them from rolling during placement, and also effectively protects the steel coils themselves. It is flexible and convenient to use, occupies a relatively small area, and has good practicality.

[0004] The solution also has the following problems: it is not convenient to turn the platform or adjust its height when using it, which means that it cannot be adjusted according to actual needs and has low practicality. Therefore, it has certain drawbacks.

[0005] Therefore, in order to solve the above problems, this application provides a freely rotatable steel coil turntable. Utility Model Content

[0006] The purpose of this invention is to provide a freely rotatable steel coil turntable to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a freely rotatable steel coil turntable, comprising a base, a support frame mounted on the top of the base, a geared motor mounted on one outer end of the support frame, a drive pulley mounted on the output shaft of the geared motor, a driven pulley mounted on the top of the support frame, a transmission belt mounted between the drive pulley and the driven pulley, a vertical tube mounted on the top of the driven pulley, a threaded rod mounted inside the vertical tube, and a turntable mounted on the top of the threaded rod.

[0008] Preferably, the driven pulley is provided with a rotating shaft at its bottom, which is rotatably connected to the top of the support frame, and when the driving pulley rotates, it is synchronously driven to rotate on the top of the support frame via a transmission belt.

[0009] Preferably, a servo motor is installed at the top end of the driven pulley, a driving bevel gear is installed on the output shaft of the servo motor, and a driven bevel gear is installed on the outer ring surface of the riser. The driving bevel gear and the driven bevel gear mesh with each other.

[0010] Preferably, the bottom of the riser is rotatably connected to the top of the driven pulley, and the interior of the riser is threadedly connected to the outer annular surface of the threaded rod.

[0011] Preferably, four sets of support rods are installed in a circular array on the top of the driven pulley, and a sleeve is installed at the top end of the outer ring surface of each support rod. A sliding rod is installed at the bottom of the steering platform and inside the four sets of sleeves.

[0012] Preferably, the top of the steering platform is symmetrically equipped with fixing ears at both ends, and adjusting bolts are installed on the fixing ears. A triangular block is installed at one end of the adjusting bolt. The bottom of the triangular block is slidably connected to the top of the steering platform, and an anti-slip pad is installed on the inclined surface of the steering platform.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This freely rotatable steel coil steering platform, driven by a geared motor, rotates synchronously with the driven pulley due to the friction of the transmission belt, thus increasing its operational practicality. When the servo motor starts, the driving bevel gear drives the driven bevel gear, causing the riser to rotate on top of the driven pulley. As the riser rotates on the driven pulley, the threaded rod generates axial displacement due to the relative movement of the threaded pair, raising and lowering the steering platform. This facilitates height adjustment of the steering platform. When the adjusting bolt is rotated, the triangular blocks move along the top of the steering platform, thereby adjusting the distance between the two sets of triangular blocks. This allows for limiting the movement of steel coils of different diameters, making operation convenient and improving practicality. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0021] A freely rotatable steel coil turntable, see reference. Figure 1 - Figure 4 The system includes a base 1, a support frame 2 mounted on the top of the base 1, a geared motor 3 mounted on one end of the support frame 2, a drive pulley 4 mounted on the output shaft of the geared motor 3, a driven pulley 5 mounted on the top of the support frame 2, a transmission belt 6 mounted between the drive pulley 4 and the driven pulley 5, a riser 7 mounted on the top of the driven pulley 5, a threaded rod 8 mounted inside the riser 7, and a turntable 9 mounted on the top of the threaded rod 8.

[0022] Reference Figure 1 - Figure 3 The driven pulley 5 has a rotating shaft at its bottom that is rotatably connected to the top of the support frame 2. When the driving pulley 4 rotates, it is synchronously driven to rotate on the top of the support frame 2 via the transmission belt 6. When the driving pulley 4 is driven by the reduction motor 3, the driven pulley 5 rotates synchronously due to the friction of the transmission belt 6, ensuring the continuity and stability of the rotational motion, thereby realizing the rotation of the turntable 9 and increasing its operational practicality.

[0023] Reference Figure 1 - Figure 4A servo motor 10 is mounted on the top end of the driven pulley 5. A drive bevel gear 11 is mounted on the output shaft of the servo motor 10. A driven bevel gear 12 is mounted on the outer ring surface of the riser 7. The drive bevel gear 11 and the driven bevel gear 12 mesh with each other. When the servo motor 10 starts, the drive bevel gear 11 drives the driven bevel gear 12, causing the riser 7 to rotate on the top of the driven pulley 5. The bottom of the riser 7 is rotatably connected to the top of the driven pulley 5, and the interior of the riser 7 is threadedly connected to the outer ring surface of the threaded rod 8. When the riser 7 rotates on the driven pulley 5, the threaded rod 8 generates axial displacement due to the relative movement of the threaded pair, thereby raising and lowering the steering table 9, which facilitates the height adjustment of the steering table 9.

[0024] Reference Figure 3 - Figure 4 Four sets of support rods 13 are installed in a ring array on the top of the driven pulley 5. A sleeve 14 is installed at the top end of the outer ring surface of each support rod 13. A sliding rod 15 is installed at the bottom of the steering platform 9 and inside the four sets of sleeves 14. When the steering platform 9 is raised or lowered, the sliding rod 15 slides in the sleeve 14 to provide radial support, thereby ensuring the stability of the raising and lowering of the steering platform 9.

[0025] Reference Figure 1 - Figure 2 The top of the steering platform 9 is symmetrically equipped with fixing ears 16 at both ends. Adjusting bolts 17 are installed on the fixing ears 16. A triangular block 18 is installed on one end of the adjusting bolt 17. The bottom of the triangular block 18 is slidably connected to the top of the steering platform 9. An anti-slip pad 19 is installed on the inclined surface of the steering platform 9. When the adjusting bolt 17 is rotated, the triangular block 18 moves along the top of the steering platform 9, thereby realizing the adjustment of the distance between the two sets of triangular blocks 18. This facilitates the limiting of steel coils of different diameters. By setting the anti-slip pad 19, the friction between the triangular block 18 and the outside of the steel coil is increased, making the steel coil more stable.

[0026] The implementation principle of a freely rotatable steel coil turntable in this application embodiment is as follows: When the turntable is in use, when the drive pulley 4 is driven by the reduction motor 3, the driven pulley 5 rotates synchronously due to the friction of the transmission belt 6, ensuring the continuity and stability of the rotational motion, thereby realizing the rotation of the turntable 9 and increasing its operability. When the servo motor 10 is started, the drive bevel gear 11 drives the driven bevel gear 12, causing the riser 7 to rotate on the top of the driven pulley 5. When the riser 7 rotates on the driven pulley 5, the threaded rod 8 generates axial displacement due to the relative movement of the threaded pair, realizing the lifting and lowering of the turntable 9, thereby facilitating the operation of the turntable 9. The height is adjusted. When the steering platform 9 is raised or lowered, the slide rod 15 slides in the sleeve 14 to provide radial support, thereby ensuring the stability of the steering platform 9 during raising and lowering. When the adjusting bolt 17 is rotated, the triangular block 18 moves along the top of the steering platform 9, thereby realizing the adjustment of the distance between the two sets of triangular blocks 18, which is convenient for limiting steel coils of different diameters. By setting the anti-slip pad 19, the friction between the triangular block 18 and the outside of the steel coil is increased, making the steel coil more stable and convenient to operate. The external spiral opening angle of the threaded rod 8 and the adjusting bolt 17 is 20 degrees, and the thread self-locking condition meets the following formula calculation: self-locking condition = friction coefficient * tan (spiral angle) ≥ 1.
