Description
Technical Field
[0001] This utility model relates to the field of port transportation and hoisting technology, and in particular to a coiled steel core-pulling repair device. Background Technology
[0002] During the transport and hoisting of coiled steel, the binding straps are prone to breakage, and collisions with the lifting equipment can cause core pulling. When the coiled steel and the lifting equipment separate, the pulling force of the lifting equipment causes the core of the coiled steel to protrude to varying degrees, forming a tower shape, resulting in core pulling. This not only affects the transport quality of the steel coil and makes the sides of the coil uneven, but more importantly, it easily damages the coiled steel. Furthermore, after the hoisting process is completed, workers cannot reach the back of the coiled steel to repair it, making the core pulling problem difficult to resolve.

[0023] like Figure 1 and Figure 2 As shown, a coiled steel core-pulling repair device includes a first support frame 1, a second support frame 2, a positioning frame 3, a hinge frame 4, and a drive mechanism 6.
[0024] like Figure 1 and Figure 2 As shown, the first support frame 1 and the second support frame 2 are arranged at intervals relative to each other, and their bottom ends are aligned. In this embodiment, the first support frame 1 and the second support frame 2 can be made of, but are not limited to, angle steel, and the length of the first support frame 1 is less than the length of the second support frame 2. In a preferred embodiment, the second support frame 2 is further provided with a bracket 5, which is used to place the drive mechanism 6. Under the action of the bracket 5, the drive mechanism 6 can be reliably positioned and also provides support, reducing labor intensity.
[0025] like Figure 1 and Figure 2 As shown, the positioning frame 3 is located between the first support frame 1 and the second support frame 2. The positioning frame 3 includes an adjustment component 31 and a fixing component 30.
[0026] The adjusting assembly 31 includes a connecting rod 310 and an adjusting rod 311 threadedly connected to the connecting rod 310. One end of the connecting rod 310 is fixed to the first support frame 1, and the other end of the connecting rod 310 is threadedly connected to the adjusting rod 311. The other end of the adjusting rod 311 is mounted on the second support frame 2 through a limiting structure. In a preferred embodiment, the limiting structure is a first limiting sleeve 312 provided on the second support frame 2, that is, the adjusting rod 311 passes through the first limiting sleeve 312, and the adjusting rod 311 can reliably rotate under the action of the first limiting sleeve 312. Specifically, the connecting rod 310 has a hollow structure on the side near the second support frame 2, the inner wall of the hollow structure has an internal thread, and the outer side of the adjusting rod 311 has an external thread.
[0027] In this utility model, the drive mechanism 6 is detachably connected to the end of the adjusting rod 311 near the second support frame 2. After the drive mechanism 6 is started, it can drive the adjusting rod 311 to rotate reliably under the limit of the first limiting sleeve 312. Under the action of the threaded connection, the relative movement between the adjusting rod 311 and the connecting rod 310 is realized.
[0028] The fixing component 30 includes a fixing frame 300 and a telescopic rod 301 slidably connected to the fixing frame 300. One end of the fixing frame 300 is fixed to the first support frame 1, and the other end is fixed to the connecting rod 310. One end of the telescopic rod 301 is located inside the fixing frame 300, and the other end is fixed to the second support frame 2. In this embodiment, the fixing frame 300 can be, but is not limited to, an L-shaped frame. A first reinforcing rod 302 is provided between the fixing frame 300 and the connecting rod 310. The first reinforcing rod 302 enhances the structural strength, making the fixing component 30 less prone to damage and improving its service life. In this embodiment, the fixing frame 300 includes a horizontal section, which is arranged parallel to the connecting rod 310. When the adjusting rod 311 rotates, it drives the telescopic rod 301 to extend and retract within the fixing frame 300, thereby realizing the movement of the fixing component 30.

In this embodiment, a triangular baffle 43 is provided on the top of the first support frame 1, and the support rod 40 is provided on the inner side of the triangular baffle 43. Under the action of the triangular baffle 43, the hinge frame 4 can only rotate on one side, thus achieving a hinged connection. In this embodiment, a second reinforcing rod 42 is provided between the support rod 40 and the connecting rod 41. Under the action of the second reinforcing rod 42, the structural strength of the hinge frame 4 is enhanced, making it less prone to damage and improving its service life. In a preferred embodiment, an adjusting handle 410 is provided at one end of the connecting rod 41 near the second support frame 2, which allows the hinge frame 4 to be easily rotated.
[0030] like Figure 1 and Figure 2 As shown, in actual use, the adjustment handle 410 is operated to rotate the hinge frame 4 so that it rests on the side of the positioning frame 3. The present invention is then inserted into the center of the core-pulling coil, with the first support frame 1 placed on the coil and the second support frame 2 blocking the outer end of the coil. The drive mechanism 6 is activated to rotate the adjustment rod 311. Through relative movement, the adjustment rod 311 and the telescopic rod 301 are pulled out, causing the first support frame 1, the positioning frame 3, and the hinge frame 4 to move towards the other end of the coil. After they are in place, the hinge frame 4 is flipped up so that the top of the hinge frame 4 rests against the coil. The adjustment rod 311 is then rotated again, thereby moving the coil and solving the technical problem of core-pulling of the coil. Moreover, the present invention is simple to operate, simple in structure, and easy to implement.
