AI Technical Summary
Existing steel strand winding and unwinding devices are prone to scratching the surface of the steel strand when moving horizontally, and the long length of the device is not conducive to miniaturization.
The design employs a drive mechanism and threaded rod to allow the arc-shaped winding plate to separate from the steel strand before horizontal movement. Support blocks prevent bending deformation, while limiting grooves and ball bearings reduce friction, enabling smooth movement of the arc-shaped winding plate.
This avoids scratches on the steel strands, improves product quality, and shortens the device length, which is beneficial for miniaturization.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of steel strand winding equipment, specifically a steel strand winding and unwinding device. Background Technology
[0002] Steel strand is a cable-like material made by twisting multiple high-strength steel wires together using a specific process. Its structure typically consists of a central steel wire surrounded by multiple spirally wound wires, forming a high-strength, high-toughness whole. It possesses characteristics such as high tensile strength, good flexibility, and strong corrosion resistance, and is widely used in bridge, building, and water conservancy engineering fields. As a reinforcing material for prestressed concrete structures or a core load-bearing component in large hoisting and anchoring systems, it effectively improves structural load-bearing capacity and extends service life. Because steel strand itself has high stiffness and strength, directly winding it into a coil is difficult; therefore, specialized winding and unwinding devices are required.
[0003] Chinese patent CN222082144U discloses a steel strand winding and unwinding device. This device is equipped with a lifting platform, which can provide good support for the steel strand, reduce the friction between the steel strand and the winding roller caused by the weight of the steel strand, make it easy to separate the steel strand from the winding roller, and also prevent the winding roller from deforming and bending when only one end of the winding roller is supported.
[0004] In the above-mentioned device, when the winding roller is moved horizontally, the winding roller and the steel strand are still in contact, and there is a certain friction between them, which can easily cause damage to the surface of the steel strand and cause scratches. In addition, due to the setting of the first insertion post, the horizontal movement distance of the winding roller is at least the sum of the length of the winding roller and the length of the first insertion post, which results in a long movement distance of the winding roller. The overall length of the device also needs to be set longer, which is not conducive to miniaturization. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-5 This utility model provides a steel strand winding and unwinding device, including a base plate 1 and a support device 108. A fixed seat 101 is installed on one side of the upper surface of the base plate 1, and a first rotating disk 102 is rotatably installed inside the fixed seat 101. A movable seat 103 is installed on the other side of the upper surface of the base plate 1 via a movable module 2, and a second rotating disk 104 is rotatably installed inside the movable seat 103. Four first through slots 105 are arranged in a circular array on the surface of the second rotating disk 104. An arc-shaped winding plate 106 is slidably installed inside the first through slots 105, and a first threaded rod 107 is rotatably installed inside the first through slots 105, and the first threaded rod 107 passes through the interior of the arc-shaped winding plate 106 and is threadedly connected to it. A drive mechanism 3 is provided inside the second rotating disk 104, and the drive mechanism 3 can simultaneously drive the four first threaded rods 107 to rotate.
[0025] In use, the four first threaded rods 107 are driven to rotate simultaneously by the drive mechanism 3. Since the inner wall of the first through groove 105 limits the arc-shaped winding plate 106, the four arc-shaped winding plates 106 can move simultaneously along the length direction of the first threaded rods 107, so that the four arc-shaped winding plates 106 can unfold outward. Then, the steel strand can be wound up by the four arc-shaped winding plates 106.
[0026] After the steel strand is wound up, the first threaded rod 107 is used to support the steel strand. Then, the four first threaded rods 107 are driven to rotate in opposite directions at the same time by the drive mechanism 3, which drives the four arc-shaped winding plates 106 to retract towards the center of the second rotating disk 104, so that they are separated from the steel strand. Then, the second rotating disk 104 is driven to move horizontally by the moving module 2, so that the arc-shaped winding plates 106 are pulled out from the inside of the steel strand, and the steel strand can be taken out.
[0027] Since the arc-shaped winding plate 106 does not come into contact with the steel strand during the extraction process, it can avoid scratching the steel strand, ensuring the integrity of the steel strand and improving product quality. In addition, the horizontal movement distance of the arc-shaped winding plate 106 is consistent with its length, which shortens the overall length of the device and is conducive to the miniaturization of the device.
[0028] Preferably, the drive mechanism 3 includes a mounting groove 301 formed on the surface of the second rotating disk 104. A rotating shaft 302 is rotatably mounted inside the mounting groove 301. A drive bevel gear 303 is mounted on the outer surface of the rotating shaft 302. The ends of the four first threaded rods 107 all penetrate into the mounting groove 301 and are mounted with driven bevel gears 304. The four driven bevel gears 304 are all meshed with the drive bevel gears 303.
[0029] When the rotating shaft 302 is rotated, it drives the driving bevel gear 303 to rotate. Since the driving bevel gear 303 is simultaneously engaged with four driven bevel gears 304, it can simultaneously drive the four first threaded rods 107 to rotate, thus achieving the purpose of the four arc-shaped winding plates 106 simultaneously moving closer to or further away from the center of the second rotating disk 104.
[0030] Preferably, the surface of the first rotating disk 102 is provided with four second through slots 4 in a circular array, and the end of the arc-shaped winding plate 106 can extend through the second through slots 4 to the other side of the first rotating disk 102. A cross plate 401 is installed on the outer surface of the first rotating disk 102 by a translation mechanism 5, and a support block 402 is installed at each of the four corners of the cross plate 401.
[0031] First, move the four arc-shaped winding plates 106 to the side furthest from the center of the second rotating disk 104. After the arc-shaped winding plates 106 pass through the second through slot 4 and extend to the other side, the cross plate 401 can be moved towards the first rotating disk 102 by the translation mechanism 5, and the support block 402 is pressed against the inner side of the end of the arc-shaped winding plate 106, so as to support the arc-shaped winding plate 106 and avoid the arc-shaped winding plate 106 being supported on one side and bending and deforming under the gravity of the steel strand.
[0032] Preferably, the translation mechanism 5 includes a second threaded rod 501 rotatably mounted on the outer surface of the first rotating disk 102. The end of the second threaded rod 501 extends through to the other side of the cross plate 401 and is threadedly connected thereto. A handwheel 502 is mounted on the end of the second threaded rod 501. Four guide posts 503 are connected in a circular array on the surface of the first rotating disk 102, and the cross plate 401 is slidably mounted on the four guide posts 503.
[0033] After the steel strand is removed from the support device 108, the four arc-shaped winding plates 106 are first driven outward by the drive mechanism 3, and then the second rotating disk 104 is driven closer to the first rotating disk 102 by the moving module 2. At this time, the worker can manually rotate the first rotating disk 102 to ensure that the end of the arc-shaped winding plate 106 can pass through the second through slot 4 and extend to the other side. Then the worker turns the handwheel 502 to drive the second threaded rod 501 to rotate. Since the four guide posts 503 limit the cross plate 401, the cross plate 401 can move horizontally towards the first rotating disk 102 under the action of the threaded connection and abut against the inner side of the end of the arc-shaped winding plate 106, thereby supporting the arc-shaped winding plate 106 and preventing the arc-shaped winding plate 106 from bending and deforming under the gravity of the steel strand due to one-sided support.
[0034] Preferably, the end of the arc-shaped winding plate 106 is provided with a first inclined surface 504, and the end of the support block 402 is provided with a second inclined surface 505.
[0035] Because the steel strand has a certain shrinkage force after winding, when the support block 402 is separated from the arc-shaped winding plate 106 by the translation mechanism 5, the shrinkage force generated by the steel strand will exert a certain force on the arc-shaped winding plate 106. At this time, the arc-shaped winding plate 106 is supported on one side, which makes the arc-shaped winding plate 106 prone to bending and deformation under the action of the shrinkage force of the steel strand. In addition, the arc-shaped winding plate 106 may also be bent due to collision during daily use. At this time, through the setting of the first inclined surface 504 and the second inclined surface 505, when the translation mechanism 5 drives the support block 402 to contact the arc-shaped winding plate 106, the second inclined surface 505 and the first inclined surface 504 squeeze each other, thereby reshaping the bent arc-shaped winding plate 106 and ensuring the horizontality of the arc-shaped winding plate 106.
[0036] Preferably, a sleeve 6 is installed on the outer surface of the second rotating disk 104, the end of the rotating shaft 302 extends to the outside of the sleeve 6, a drive motor 601 is installed on the surface of the movable seat 103, and a pulley set 602 is provided between the output shaft of the drive motor 601 and the outer surface of the sleeve 6 for transmission.
[0037] Under the transmission action of the pulley group 602, the second rotating disk 104 can be driven by the drive motor 601 to rotate, thereby achieving the purpose of winding the steel strand.
[0038] Preferably, limiting grooves are provided on both sides of the inner wall of the first through groove 105, and limiting blocks are provided on both sides of the outer surface of the arc-shaped winding plate 106. The limiting blocks are set in the limiting grooves, and the outer surface of the limiting blocks is provided with balls, which roll in contact with the inner wall of the limiting groove.
[0039] By setting the limiting groove and limiting block, the arc-shaped winding plate 106 is limited within the second rotating disk 104, keeping it in a horizontal state and preventing the first threaded rod 107 from being subjected to forces in other directions. Furthermore, by setting the ball bearings, the frictional resistance between the limiting block and the limiting groove can be reduced, wear and tear can be reduced, and service life can be improved.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
