Normal transportation using a three-claw internal support type lifting device has the following problems: 1. The claws are prone to slipping when they are engaged with the packing strap, which may cause one end of the claw to slip off; 2. Low efficiency, as employees need to readjust the position of the claws whenever slippage occurs.

[0003] Therefore, how to quickly clamp / release steel bar bundles while reducing the time required to adjust the position of the chucks is an urgent problem to be solved. Utility Model Content

[0004] This utility model proposes a single-bundle steel bar transfer tool, which solves the problem of low efficiency in clamping / releasing steel bar bundles by existing chucks.

[0005] The technical solution of this utility model is as follows: A steel bar single bundle transfer tool includes a main body component, the main body component includes a ring seat and a protective cover, the protective cover is fixedly connected to one side of the top of the ring seat, an inner rotating component is provided inside the ring seat and the protective cover, the inner rotating component includes an inner rotating ring rotatably connected inside the ring seat, the inner rotating component also includes four sets of arc-shaped push plates fixedly connected in a ring to the inner side of the inner rotating ring, and an inner pushing component is also provided inside the ring seat that can be squeezed and pushed inward by the arc-shaped push plates to complete the positioning and clamping of the steel bar ring.

[0006] Preferably, the internal rotation assembly includes a forward and reverse motor, which is fixedly installed inside the protective cover. The internal rotation assembly also includes a worm gear, which is fixedly connected to the output end of the forward and reverse motor.

[0007] Preferably, the inner rotating assembly further includes a rotating shaft, which is rotatably connected inside the protective cover. A worm gear is fixedly connected to the middle of the outer side of the rotating shaft, and the worm gear is in contact with the worm and is meshed and rotatably connected.

[0008] Preferably, the inner rotating assembly further includes a toothed disc, which is fixedly connected to the bottom of the rotating shaft. The inner rotating assembly also includes a toothed groove group, which is distributed in a ring on the outer side of the inner rotating ring. The toothed groove group is in contact with the toothed disc and is meshed and rotatably connected.

[0009] Preferably, the inner rotating assembly further includes ball bearings, which are rotatably connected in a ring to the upper and lower sides of the forward and reverse motors, and the ball bearings are in contact with the inner side of the ring seat.

[0010] Preferably, the push-in assembly includes four sets of connecting plates fixedly connected to the inner side of the ring seat. The push-in assembly also includes a slide rod, which is slidably connected to the middle of the connecting plates. The push-in assembly also includes a spring ring, which is sleeved on the outside of the slide rod.

[0011] Preferably, the push assembly further includes a push rod, which is fixedly connected to the slide rod. A sleeve rod is fixedly connected to the outside of the push rod. The push assembly further includes a positioning clamp, which is located below the push rod and is fixedly connected to the push rod.

[0012] Preferably, the main body component further includes a hanging ear, which is fixedly connected to the top of the ring seat in a ring shape.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Worm gear drive and self-locking design ensure clamping stability.

[0015] Through the meshing transmission of the worm gear and worm, combined with the meshing linkage of the toothed disc and the inner rotating ring's tooth groove group, precise rotation control of the inner rotating ring is achieved. The self-locking characteristic of the worm gear transmission effectively prevents loosening or reverse rotation caused by external forces during clamping, ensuring stable and reliable clamping force of the positioning clamp on the steel bar bundle. This design solves the risk of slippage caused by uneven force or vibration in traditional chucks, significantly improving the safety of the transfer process.

[0016] II. Four sets of synchronous adaptive clamping structures improve efficiency and versatility.

[0017] The four sets of arc-shaped push plates on the inner side of the inner rotating ring work in conjunction with the slide rod, spring ring, and positioning clamping plate of the inner pushing assembly to form a symmetrical clamping mechanism. When the motor drives the inner rotating ring to rotate, the arc-shaped push plates synchronously push the four sets of positioning clamping plates to retract towards the center. Combined with the anti-slip layer applying force evenly, this design can accommodate steel bar bundles of different diameters. After clamping, the motor reverses to drive the arc-shaped push plates to disengage, and the spring ring automatically resets the positioning clamping plates, achieving rapid release. This design avoids repeated manual adjustment of the jaw positions, significantly shortens the transfer cycle, and enhances adaptability to steel bar bundles of different specifications.

[0027] Please see Figure 3 The inner rotating assembly 2 includes a forward and reverse motor 21, which is fixedly installed inside the protective cover 12. The inner rotating assembly 2 also includes a worm gear 211, which is fixedly connected to the output end of the forward and reverse motor 21.

[0028] The inner rotating assembly 2 also includes a rotating shaft 22, which is rotatably connected inside the protective cover 12. A worm wheel 221 is fixedly connected to the middle of the outer side of the rotating shaft 22. The worm wheel 221 is in contact with the worm 211 and is meshed and rotatably connected.

[0029] The inner rotating assembly 2 also includes a toothed disk 222, which is fixedly connected to the bottom of the rotating shaft 22. The inner rotating assembly 2 also includes a toothed groove group 232, which is distributed in a ring on the outside of the inner rotating ring 23. The toothed groove group 232 is in contact with the toothed disk 222 and is meshed and rotated.

[0030] The inner rotating assembly 2 also includes a ball bearing 231, which is rotatably connected to the upper and lower sides of the forward and reverse motor 21 in a ring shape, and the ball bearing 231 is in contact with the inner side of the ring seat 11.

[0031] By starting the forward and reverse motor 21, the worm 211 can be driven to rotate, and under the meshing cooperation of the worm 211 and the worm wheel 221, the rotating shaft 22 located inside the worm wheel 221 and the gear disk 222 located at the bottom of the rotating shaft 22 can rotate synchronously.

[0032] The self-locking effect of the meshing between the worm 211 and the worm wheel 221 can prevent loosening after rotational changes;

[0033] By providing a protective cover 12 on the top of the ring seat 11 to protect the inner rotating component 2, it is possible to prevent foreign objects from entering and causing jamming between the worm 211 and the worm wheel 221.

[0037] The ring seat 11 is assembled with the external hoisting and transfer equipment via the lug 111;

[0038] When the arc-shaped push plate 24 rotates with the inner rotating ring 23 inside the ring seat 11, the arc-shaped push plate 24 will contact and gradually push the push rod 33 inward. At this time, the positioning clamp 34 fixed below the push rod 33 by the sleeve rod 331 can be pushed towards the axis of the ring seat 11 in sync. With the four sets of positioning clamps 34 working in conjunction with the anti-slip layer 341 to push towards the axis in sync, positioning work can be carried out on steel bar bundles of different sizes within the range.

[0039] Specifically, after the steel bar bundle is transported to the target position, starting the forward and reverse motor 21 drives the worm gear 211 to reverse, which allows the arc-shaped push plate 24 to rotate and reset with the inner rotating ring 23. At this time, the arc-shaped push plate 24 gradually disengages from the push rod 33, and the push rod 33 can also complete the reset and disengage from the steel bar bundle under the elastic action of the spring ring 321.

[0040] Working principle:

[0041] First, the ring seat 11 is assembled with the external hoisting and transfer equipment using the lugs 111;

[0042] After the steel bar is placed in the ring seat 11 between the four sets of positioning clamps 34, the forward and reverse motor 21 is started to drive the worm 211 to rotate. Under the meshing cooperation of the worm 211 and the worm wheel 221, the rotating shaft 22 located inside the worm wheel 221 and the gear disk 222 located at the bottom of the rotating shaft 22 can rotate synchronously.

[0043] Under the meshing and rotation of the toothed disc 222 and the toothed groove group 232, the inner rotating ring 23 and the arc-shaped push plate 24 rotate synchronously in the ring seat 11. At this time, the arc-shaped push plate 24 will contact and gradually push the push rod 33 inward. At this time, the positioning clamp 34 fixed below the push rod 33 by the sleeve rod 331 can be pushed synchronously towards the axis of the ring seat 11. By using four sets of positioning clamps 34 in conjunction with the anti-slip layer 341 to push synchronously towards the axis, positioning work can be carried out on steel bar bundles of different sizes within the range.

[0044] Specifically, after the steel bar bundle is transported to the target position, starting the forward and reverse motor 21 drives the worm gear 211 to reverse, which allows the arc-shaped push plate 24 to rotate and reset with the inner rotating ring 23. At this time, the arc-shaped push plate 24 gradually disengages from the push rod 33, and the push rod 33 can also complete the reset and disengage from the steel bar bundle under the elastic action of the spring ring 321.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
