Description

Technical Field

[0001] The utility model relates to the technical field of fixtures, in particular to a steel coil fixture. Background Art

[0002] In the finished product area of the hot coil production line, an electric horizontal coil clamping crane is used to complete the transfer and storage of finished steel coils. The fixture of the electric horizontal coil clamping crane is movably connected to the crane. During the transfer of the steel coil, due to the uneven skills of the crane operators in stabilizing the hook, the fixture often swings back and forth during the clamping and alignment of the steel coil, causing the clamping arm of the fixture to collide with the end face of the finished steel coil, resulting in deformation and damage to both end faces of the finished steel coil. Especially when lifting thin-gauge steel coils, this situation is particularly obvious, often producing defective products and low user satisfaction. Summary of the Utility Model

[0025] Please refer to Figure 1 , this embodiment provides a steel coil clamp, which includes a clamp body 1, a clamping mechanism, and an anti-collision mechanism. The clamping mechanism includes two clamping arms 2, and the two clamping arms 2 are respectively rotatably arranged at both ends of the clamp body 1 along the clamping direction, that is, the two clamping arms 2 are respectively rotatably arranged at the left and right ends of the clamp body 1. The vertical part of the clamping arm 2 is the clamping part 3, and a hook is connected to the bottom of the clamping part 3. When the two clamping arms 2 approach each other, the steel coil 5 is clamped by the clamping parts 3 and the hooks of the two clamping arms 2. The two hooks extend into the inner hole of the steel coil 5, and the end face of the steel coil 5 abuts against the inner wall of the clamping part 3. When the two clamping arms 2 move away from each other, the two hooks withdraw from the inner hole of the steel coil 5, and the steel coil 5 is released. The anti-collision mechanism is used to buffer the impact of the end face of the steel coil 5 in the horizontal direction. The anti-collision mechanism includes a roller 4 rotatably arranged in the clamping part 3. The outer peripheral wall of the roller 4 protrudes from the inner wall of the clamping part 3, and the roller 4 can also be arranged on the outer side wall of the clamping part 3. The clamping part 3 includes two clamping plates respectively arranged on the front and rear sides of the clamping arm 2, and there is a gap between the two clamping plates. The roller 4 is arranged vertically in the gap between the two clamping plates. The horizontal impact of the steel coil 5 is converted into rolling friction through the roller 4, reducing or even avoiding the damage to the end face of the steel coil 5 by the inner wall of the clamping arm 2 during the impact.

[0026] In one embodiment, as Figure 1 shown, a plurality of rollers 4 are arranged vertically on each clamping part 3. The plurality of rollers 4 can increase the anti-collision area between the clamping part 3 and the end face of the steel coil 5, and improve the protection effect on the end face of the steel coil 5.

[0027] In one embodiment, asFigure 3 As shown in the figure, the anti-collision mechanism further includes a roller 4 shaft disposed within the clamping portion 3. The roller 4 shaft is disposed between two clamping plates of the clamping portion 3, and both ends of the roller 4 shaft are respectively disposed on the two clamping plates of the clamping portion 3. The roller 4 is rotatably disposed within the clamping portion 3 via the roller 4 shaft.

[0028] In one embodiment, as Figure 3 shown, the anti-collision mechanism further includes two pressing shaft clamping plates 8 and two supporting plates 7 disposed within the clamping portion 3. The supporting plates 7 and the pressing shaft clamping plates 8 are used to fix the roller 4 shaft. The two supporting plates 7 are respectively disposed on opposite sides of the two clamping plates of the clamping portion 3. The bottom outer peripheral walls at both ends of the roller 4 shaft are respectively disposed on the tops of the two supporting plates 7, and the top shapes of the two supporting plates 7 are adapted to the shape of the roller 4 shaft. The two pressing shaft clamping plates 8 are respectively disposed on the top outer peripheral walls at both ends of the roller 4 shaft, pressing the roller 4 shaft onto the supporting plates 7.

[0029] In one embodiment, the supporting plate 7 is an arc-shaped supporting plate 7, and the top shape of the supporting plate 7 is an arc shape adapted to the outer peripheral wall of the roller 4 shaft.

[0030] In one embodiment, as Figure 3 shown, a bushing 9 is disposed between the roller 4 shaft and the roller 4. The bushing 9 is sleeved on the outer wall of the roller 4 shaft and is also sleeved within the inner hole of the roller 4 to prevent the axial movement of the roller 4.

[0031] In one embodiment, the outer diameter of the roller 4 is greater than the width of the clamping portion 3 in the clamping direction, that is, the outer diameter of the roller 4 is greater than the width of the clamping portion 3 in the left-right direction, such that the outer peripheral wall of the roller 4 can protrude from the inner wall of the clamping portion 3.

[0032] In one embodiment, the roller 4 is a heat-resistant nylon roller 4. The heat-resistant nylon roller 4 is resistant to high temperatures and can buffer and absorb vibrations, enhancing the protection effect on the end face of the steel coil 5.

[0033] In one embodiment, the roller 4 is a brass roller 4 or a mild steel roller 4. The brass roller 4 or the mild steel roller 4 has better heat resistance and will not deform in high-temperature areas.

[0034] The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention.
