Description

TECHNICAL FIELD

[0001] The utility model relates to steel band production technical field, especially a hot rolled steel band binding structure. BACKGROUND

[0002] At present, the width of most hot rolled steel bands is small, so the axial length of the steel coil is short after the hot rolled steel band is rolled into a steel coil. At present, the storage of such steel coils is mostly in a horizontal state. Because the axial length of the steel coil is short, the stability of a single steel coil is limited, and the steel coil is prone to tilting, which affects the safety of storage.

[0003] Therefore, the current storage method is to bundle three or more steel coils together by steel bands to form a steel coil bundle, and then stack several steel coil bundles together. Specifically, three or more steel coils are arranged side by side, and the end faces of adjacent steel coils are in close contact. Then the steel band is passed through the inner holes of the steel coils, and the two ends of the steel band are bundled together on the outer circumference of the steel coil in a mutually entangled manner. Generally, two or more steel bands are bundled, and the steel bands are evenly distributed in the circumferential direction of the steel coil.

[0004] Although the above method can bundle three or more steel coils together, in order to avoid the steel band crushing the surface layer of the hot rolled steel, the bundling of the steel band is generally not too tight. This not only weakens the limiting effect of the steel band on the steel coil, but also easily causes the steel band to be unstable in the position that needs to be bundled, thereby easily causing the steel coil to loosen and the steel coils to tilt relative to each other during storage, which affects the convenience and stability of the storage of the steel coil.

[0005] In addition, although the axial length of the steel coil is short, the relative weight is still very large, which easily causes the steel band to bear a large force when the steel coils tilt relative to each other, which easily causes the steel band to break or the bundled end to loosen, thereby affecting the stability and safety of the storage of the steel coil.

[0006] Therefore, it is necessary to design a hot rolled steel band bundling structure to solve the above technical problems. INVENTION CONTENTS

[0007] The utility model aims at solving the above problems and deficiencies, and provides a hot rolled steel band bundling structure, which can stably and reliably bundle the steel coil, greatly reduces the loosening of the steel coil and the tilting of the steel coils relative to each other, thereby improving the convenience and stability of the storage of the steel coil. In the case of greatly reducing the tilting of the steel coils relative to each other, the force acting on the steel band can be avoided, which can greatly reduce the probability of the steel band breaking or loosening, thereby improving the stability and safety of the storage of the steel coil.

[0021] As Figures 1 to 3 The utility model discloses a kind of hot rolled steel band binding structures, including at least two steel bands 1, several by hot rolled steel band curling and form steel roll 2, for realizing the invention purpose of the utility model, still include position cylinder 3, the inner circumferential surface of the two ports of position cylinder 3 is respectively provided with a plurality of surrounding its axial center line evenly arranged clamping ware 4, each steel roll 2 is housed in position cylinder 3, each steel band 1 is evenly arranged around steel roll 2, and make the two ends of each steel band 1 respectively curved into the two ports of position cylinder 3, also make the two ends of steel band 1 respectively be clamped by corresponding clamping ware 4.

[0022] In the hot-rolled steel strip bundling structure, not only is the limiting cylinder 3 provided for the steel roll 2 to be sleeved, but also a plurality of clamps 4 are arranged on the inner circumferential surface of the two ends of the limiting cylinder 3 and are uniformly arranged around the axial center line of the limiting cylinder 3. Thus, the steel strip 1 can be accurately and stably limited to the appropriate circumferential position of the steel roll 2 by using the clamps 4 while the position of the steel roll 2 is limited by using the limiting cylinder 3. Therefore, the steel strip 1 can stably and reliably limit the steel roll 2, and the steel strip 1 and the steel roll 2 can maintain high stability and cannot be displaced. Thus, the hot-rolled steel strip bundling structure can stably and reliably bundle the steel rolls, can greatly reduce the loosening of the steel rolls and the relative skewing between the steel rolls, and can improve the convenience and stability of the storage of the steel rolls. In addition, the force on the steel strip can be reduced, the probability of the breakage and loosening of the steel strip can be greatly reduced, and the stability and safety of the storage of the steel rolls can be improved.

[0023] As shown in Figure 1 With Figure 2 In actual assembly, the steel rolls 2 are sleeved on the limiting cylinder 3 side by side, and the end faces of the adjacent steel rolls 2 are abutted together. Then, the middle part of the steel strip 1 is tightly attached to the outer wall of the steel roll 2, and the two ends of the steel strip 1 are tightly attached to the outer end faces of the steel rolls 2 arranged at the two ends. Then, the two ends of the steel strip 1 are bent into the two ends of the limiting cylinder 3. Finally, the two ends of the steel strip 1 are clamped by the corresponding clamps 4. Thus, the steel strip 1 can stably limit the steel rolls 2 on the limiting cylinder 3, and the steel rolls 2 formed by the hot-rolled steel strip can be stably limited together, and the steel rolls 2 formed by the hot-rolled steel strip can be stably and safely stored.

[0024] In the hot-rolled steel strip bundling structure, the limiting cylinder 3 and the clamps 4 can be repeatedly used, and the steel strip 1 can also be repeatedly used without deformation, cracking, and affecting the secondary use. Thus, the cost can be controlled.

[0025] As shown in Figures 1 to 3 The clamp 4 includes a clamping seat 41 and a clamping screw 42. The clamping seat 41 is provided on the inner wall of the limiting cylinder 3, and the end of the steel strip 1 is clamped by the clamping screw 42 and the hole wall of the clamping hole 411. Such a clamp 4 is very simple and reliable, which can not only facilitate manufacturing, but also facilitate stable and reliable clamping, and can be easily disassembled, thereby further improving the reliability and applicability of the hot-rolled steel strip bundling structure.

[0026] As Figure 2 shown in the figure, the clamping seat 41 is integrally formed on the inner wall of the limiting cylinder 3. This can make the clamping seat 41 have more stable and reliable clamping effect, thereby helping to further improve the reliability of the hot-rolled steel strip binding structure.

[0027] As Figures 1 to 3 shown in the figure, the clamping hole 411 is a straight hole opened through the clamping seat 41, and the penetration direction of the clamping hole 411 is the same as the axial direction of the limiting cylinder 3. The clamping device 4 further comprises a limiting rod 43, both ends of which are connected with the inner wall of the limiting cylinder 3, and the limiting rod 43 is located outside the hole opening of the clamping hole 411 towards the middle part of the limiting cylinder 3. The end part of the steel strip 1 is wound around the limiting rod 43 after passing through the clamping hole 411, and then re-enters the clamping hole 411 and is clamped by the clamping screw 42. This can further strengthen the clamping and positioning effect of the clamping device 4 on the steel strip 1, thereby helping to further improve the limiting effect of the steel strip 1 on the steel coil 2, and further helping to further improve the reliability and applicability of the hot-rolled steel strip binding structure.

[0028] As Figures 1 to 3 shown in the figure, the two parts of the steel strip 1 in the clamping hole 411 are arranged in a stacked manner and are clamped together by the clamping screw 42. This can make the clamping effect of the clamping device 4 on the steel strip 1 more stable and reliable, thereby helping to further improve the reliability of the hot-rolled steel strip binding structure.

[0029] The limiting rod 43 is a steel rod welded and fixed on the limiting cylinder 3. This can make the limiting rod 43 have high structural strength and durability, thereby making the limiting rod 43 have more stable and reliable limiting effect.

[0030] The outer surface of the limiting rod 43 is a textured anti-slip surface (not shown in the figure). This can enhance the friction between the steel strip 1 and the limiting rod 43, thereby facilitating the end part of the steel strip 1 to be more stably and reliably limited, and further helping to further improve the reliability of the clamping device 4.

[0031] The limiting cylinder 3 is a steel cylinder. This can make the limiting cylinder 3 have high structural strength and durability, which not only facilitates more reliable limiting effect on the steel coil 2, but also makes the limiting cylinder 3 have a longer reuse cycle.
