Relying on existing hoisting methods to complete the rotation and movement is time-consuming, labor-intensive, and ineffective; therefore, a steel strand rotation mechanism is needed.

[0019] 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.

[0020] Reference Figures 1-3 A steel strand turning mechanism includes a mounting base 1, which is locked to the ground by expansion screws. Support seats 2 are fixedly installed on all four sides of the top of the mounting base 1. The four support seats 2 are arranged in groups of two, and the two groups of support seats 2 are symmetrically arranged.

[0021] The top of the mounting base 1 is provided with a flipping mechanism 3 and a limit locking mechanism 4. The flipping mechanism 3 realizes the automatic flipping action of the steel strand roll. The flipping mechanism 3 includes a flipping platform 31. The outer surface of the flipping platform 31 is arc-shaped. The opposite surfaces of each set of support bases 2 are rotatably connected to an auxiliary rotating shaft 32 through bearings. The arc surfaces at both ends of the auxiliary rotating shaft 32 are fixedly installed with limit rotating wheels 33.

[0022] Specifically, the auxiliary rotating shaft 32 and the limiting rotating wheel 33 are set up to facilitate the control of the tilting platform 31 to be positioned above the limiting rotating wheel 33 for support and limiting, so that the center of gravity of the tilting platform 31 is located at the center position between the four limiting rotating wheels 33.

[0023] The arc-shaped slide rail 34 is fixedly installed on the arc surface of the flipping platform 31. The two arc-shaped slide rails 34 are symmetrically arranged, and the surface of each arc-shaped slide rail 34 is in contact with the arc surface of the two limiting wheels 33 arranged below.

[0024] Specifically, this is achieved by the squeezing contact between the arc-shaped slide rail 34 and the limiting roller 33, which forms a forced centering mechanism. Under the enormous weight of the tumbling roll and the inertial force during tumbling, this design helps to resist the minor deformations that may occur in the tumbling platform 31 or the auxiliary shaft 32, maintaining the stability of the overall mechanism geometry and ensuring the accuracy of the tumbling trajectory.

[0025] A motor base 35 is also fixedly installed on the top of the mounting base 1. A drive motor 36 is fixedly installed on the top of the motor base 35. A drive shaft 37 is fixedly installed on the output end of the drive motor 36 through a coupling. A drive gear 38 is fixedly installed on one end of the drive shaft 37. An arc-shaped rack 39 is also fixedly installed in the middle of the arc surface of the tilting platform 31. The teeth of the drive gear 38 mesh with the tooth grooves of the arc-shaped rack 39.

[0026] Specifically, the drive motor 36 can precisely control the speed and direction of rotation. Through the meshing of the drive gear 38 and the arc rack 39, the rotation angle and speed of the flipping platform 31 can be precisely controlled. The flipping action is completed automatically, which greatly reduces the intensity of manual operation and improves work efficiency, especially for heavy steel strand rolling. During operation, the drive motor 36 controls the rotation of the drive gear 38, which in turn makes the arc rack 39 rotate under meshing, controls the self-rotation adjustment operation of the flipping platform 31, and realizes the steel strand rolling and flipping operation.

[0027] The two placement surfaces of the flipping platform 31 are arranged perpendicularly. Support plates 310 are installed at both ends above one of the placement surfaces of the flipping platform 31. Both support plates 310 are triangular in shape. The inclined surfaces of the two support plates 310 are arranged from low to high from the center outward. The inclined surfaces of the support plates 310 are also provided with friction resistance grooves 311. The inner wall of the friction resistance grooves 311 is in contact with the arc surface of the steel strand roll.

[0028] Specifically, the inclined surface of the support plate 310 is designed to rise from the center outwards. This means that when the steel strand roll is placed on the support plate 310, the center of the roll will be naturally "guided" or "locked" in the central area of ​​the support plate 310. As the roll is placed towards the edge, its own weight will cause it to tend to return to the lower center point, thus automatically centering. This greatly improves the stability of placement and the accuracy of initial positioning. Friction resistance grooves 311 are provided on the inclined surface of the support plate 310, and the inner wall of the grooves contacts the arc surface of the steel strand roll. This greatly increases the friction of the contact surface; when the tilting platform 31 is stationary or slowly rotating, the strong friction can effectively prevent the steel strand roll from accidentally rolling or sliding on the support plate 310, especially on the inclined surface, which is crucial for the safety of heavy-duty rolls.

[0029] The limiting locking mechanism 4 realizes the action of locking and positioning the steel strand roll during the flipping operation of the flipping mechanism 3; the limiting locking mechanism 4 includes a limiting locking plate 41, the limiting locking plate 41 is made of iron, the arc surface of the flipping platform 31 is provided with an arc-shaped mounting groove 42, and one end of the arc surface of the limiting locking plate 41 is welded to the inner wall of the arc-shaped mounting groove 42.

[0030] Specifically, the flipping platform 31 has an arc-shaped mounting groove 42, and the arc-shaped surface of the limiting locking plate 41 is welded to it. This design allows the locking plate to fit tightly against the arc-shaped surface of the flipping platform 31, and its position is precisely determined. This ensures that the locking plate can accurately constrain the steel strand roll at the predetermined position.

[0031] A connecting base 43 is fixedly installed on the top of the mounting base 1. A connecting rod 44 is fixedly installed on the top of the connecting base 43. An electromagnetic coil 45 is fixedly installed on one end of the connecting rod 44. The magnetic end of the electromagnetic coil 45 is in corresponding contact with the surface of the limit locking plate 41. When the electromagnetic coil 45 is energized, it generates a magnetic force and attracts and locks the limit locking plate 41.

[0032] Specifically, the process of the electromagnetic coil 45 generating magnetic force when energized and the disappearance of magnetic force when de-energized is extremely rapid. This means that locking and unlocking actions can be completed in milliseconds, greatly improving operational efficiency, especially in situations requiring frequent locking and unlocking. Locking and unlocking only require controlling the on / off state of the current, which can be easily achieved through buttons, sensors, or automated control systems, without the need for manual application of physical force or complex mechanical operations. This is very helpful in improving the level of automation; the control of the electromagnetic coil 45 is very easy to connect to PLCs or other automated systems.

[0033] The steel strand turning mechanism firstly combines the symmetrically arranged support base 2 with the auxiliary rotating shaft 32 and the limiting rotating wheel 33, along with the forced centering mechanism of the arc-shaped slide rail 34, to ensure that the mechanism can maintain extremely high stability and positioning accuracy when bearing the huge weight and dynamic load of the steel strand roll, preventing deviation and ensuring accurate turning trajectory.

[0034] Secondly, the electrically driven rack and pinion system enables automated and precise control of the flipping motion, which not only significantly reduces the burden of manpower and improves work efficiency, but also allows for precise positioning according to needs, enhancing the convenience and safety of operation.

[0035] Furthermore, the special triangular support plate 310 design, combined with the friction resistance groove 311, can automatically guide the roller to be placed in the center and effectively prevent it from sliding or rolling during the flipping process, greatly enhancing the stability and safety of the operation.

[0036] Finally, the application of the electromagnetic locking mechanism makes locking and unlocking actions quick and convenient. It can quickly lock after the flipping is completed, is easy to integrate with automated control, further improves the automation level and operating efficiency of the equipment, reduces human error, and achieves efficient, safe and reliable steel strand flipping operation as a whole.

[0037] Working principle: At the start of the operation, the steel strand roll is placed on the vertically intersecting placement surface of the flipping platform 31. Utilizing the triangular support plate 310 and the friction resistance grooves 311 on its inclined surface, the roll is guided to the predetermined position and initially stabilized.

[0038] When a tilting operation is required, the control system activates the drive motor 36. The motor drives the drive shaft 37 to rotate via a coupling, and the drive gear 38 at the end of the drive shaft 37 rotates accordingly. The drive gear 38 meshes with the arc-shaped rack 39 fixed in the middle of the arc of the tilting platform 31, thereby driving the entire tilting platform 31 to rotate smoothly along a predetermined arc trajectory.

[0039] During the flipping process, the arc-shaped slide rail 34 below the flipping platform 31 maintains close compression contact with the limiting roller 33 on the auxiliary rotating shaft 32. This design not only provides support, but more importantly, it forms a forced centering mechanism, ensuring that the platform can still move precisely along the predetermined path, resist deformation, and maintain stability when bearing the rolling weight and flipping inertia.

[0040] Simultaneously, the limit locking mechanism 4 functions. When the flipping platform 31 needs to be locked and positioned after the flipping is complete, the control system energizes the electromagnetic coil 45. The electromagnetic coil 45 generates magnetic force, attracting the iron limit locking plate 41, causing it to firmly adhere. At this point, the operator can lift the rolled steel strand after the flipping is complete. When unlocking is required, the power supply to the electromagnetic coil 45 is disconnected, the magnetic force disappears, the locking state is resolved, and the flipping can continue for the next operation.

[0041] Throughout the process, the symmetrically arranged support base 2 and auxiliary rotating shaft 32 provide a solid foundation and stable rotational support for the mechanism. When the flipping operation is completed, the motor stops rotating, and the roll is safely placed in the target position.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
