[0002] In the production process of cold-rolled strip steel, steel coil loading is the starting process of the cold rolling process. The steel coil loading is completed by a walking beam. The main function of the walking beam is to transport the steel coils from the raw material warehouse to the production line area.

The static beam is mainly composed of a saddle. The steel coils are transported to the saddle by an overhead crane. In many cases, the position of the steel coils is not correct during the transportation process. The specific manifestations of the incorrect loading of the steel coils include: the position of the steel coils on the saddle is twisted (the side of the steel coils is not perpendicular to the running direction of the walking beam), and it is easy for the walking beam to roll over or drop the coils when transporting the coils forward, which seriously affects the loading rhythm of the walking beam.

[0028] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0029] Reference below Figure 1-Figure 3 A steel coil saddle 1 assembly according to an embodiment of the present application is described, and the steel coil saddle 1 assembly is used to be arranged on a walking beam device.

[0030] The steel coil saddle 1 assembly includes two steel coil saddles 1 arranged opposite to each other in the horizontal direction. The steel coil saddle 1 is provided with a plurality of inclined surfaces 13 connected in sequence along the up and down directions on one side facing the other steel coil saddle 1. The inclined surfaces 13 are inclined from top to bottom in a direction close to the other steel coil saddle 1, and the angles between the plurality of inclined surfaces 13 and the horizontal plane are arranged to increase sequentially from bottom to top.

[0031] In this embodiment, two steel coil saddles 1 are arranged at intervals in the horizontal direction, and are used to support the two sides of the central axis of the steel coil 2 respectively, wherein the steel coil saddle 1 is provided with a plurality of inclined surfaces 13 on the side facing the other steel coil saddle 1, that is, the side of the steel coil saddle 1 is provided with a plurality of inclined surfaces 13, and the inclined surfaces 13 can be used to support the steel coil 2. The two steel coil saddles 1 are completely identical, and the two steel coil saddles 1 are symmetrically arranged in the horizontal direction, so that the sides of the two steel coil saddles 1 provided with the inclined surfaces 13 are arranged opposite to each other.

[0032] The inclined surface 13 is inclined from top to bottom in a direction close to another steel coil saddle 1 so as to better support the steel coil 2, wherein the angles between each inclined surface 13 and the horizontal plane are different, and the angles between the multiple inclined surfaces 13 and the horizontal plane are arranged to increase from bottom to top, that is, the angle between the inclined surface 13 at the lowest end and the horizontal plane is the smallest, and the angle between the inclined surface 13 at the highest end and the horizontal plane is the largest, wherein the maximum angle between the inclined surface 13 and the horizontal plane is less than 90°.

[0033] It is understandable that when the steel coil 2 is placed on the steel coil saddle 1, it is generally necessary to rely on the weight of the steel coil 2 to overcome the friction resistance of the fulcrum to achieve the correct position. The steel coil 2 is generally produced in various diameters of different sizes. The larger the size and the heavier the steel coil 2, the greater the friction resistance between the steel coil 2 and the steel coil saddle 1. Figure 4 and Figure 5 According to mechanical analysis, the gravity at the point of application has a pressure component and a component that overcomes friction. If the steel coil 2 is to achieve positive movement, the component that overcomes friction must be greater than the frictional resistance. Therefore, it can be concluded that the greater the width of the two points of application between the steel coil 2 and the steel coil saddle 1, the greater the component of friction that the steel coil 2 overcomes, and the better the positive effect.

[0034] In the related art, the steel coil saddle 1 is generally provided with a single supporting surface. As the size of the steel coil 2 increases, the distance between the steel coil 2 and the supporting surface's support point will increase accordingly, but the range of the increase is limited.

[0035] In this embodiment, by providing a plurality of inclined surfaces 13 connected sequentially from bottom to top, steel coils 2 of different diameters are in contact with different inclined surfaces 13, and the slopes of the plurality of inclined surfaces 13 gradually increase from bottom to top. When the distance between the two steel coil saddles 1 remains unchanged, the fulcrum of the larger steel coil 2 is higher than the center position of the steel coil 2 compared with the fulcrum on a single slope support surface, so that the distance between the two fulcrums is larger, thereby improving the self-correcting effect of the steel coil 2.

[0036] It should be noted that the number of the inclined surfaces 13 is not limited herein, and can be two, three, four, or more than four, depending on design and use requirements.

[0037] According to the steel coil saddle 1 assembly provided in the embodiment of the present application, by setting a plurality of inclined planes 13 with different slopes, and the slope of the inclined planes 13 is set to increase from bottom to top, the contact position between steel coils 2 of different sizes and the steel coil saddle 1 can be made wider, thereby improving the alignment effect of the steel coil 2 under its own weight, reducing the probability of rolling over and falling off during transportation, and improving production efficiency.

[0038] According to some embodiments of the present application, Figure 1-Figure 3As shown, the steel coil saddle 1 may be provided with a first inclined surface 131 and a second inclined surface 132 sequentially connected in the up-down direction on one side facing the other steel coil saddle 1 .

[0039] In this embodiment, two inclined surfaces 13 can be provided on the steel coil saddle 1, and the two inclined surfaces 13 are respectively a first inclined surface 131 and a second inclined surface 132, and the lower end of the first inclined surface 131 is connected to the upper end of the second inclined surface 132, wherein the angle between the first inclined surface 131 and the horizontal plane is greater than the angle between the second inclined surface 132 and the horizontal plane.

[0040] When the diameter of the steel coil 2 is small, the force point of the steel coil 2 is located on the second inclined surface 132. When the diameter of the steel coil 2 reaches a certain size, the force point of the steel coil 2 is located on the first inclined surface 131, or even on the upper end of the first inclined surface 131. The force point of the steel coil 2 is higher than the center of the steel coil 2, so the alignment effect is better. In addition, by providing two inclined surfaces 13, the height of the steel coil saddle 1 will not be too high, reducing the probability of interference during the transportation and placement of the steel coil 2, and can adapt to the size of the existing commonly used steel coil 2.

[0041] According to some embodiments of the present application, Figure 4 As shown, the included angle α between the first inclined surface 131 and the horizontal plane can satisfy:

[0042] 35°≤α≤45°.

[0043] Among them, the value range of the angle α between the first inclined plane 131 and the horizontal plane is [35°, 45°]. By way of example, the angle α between the first inclined plane 131 and the horizontal plane can be 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45° or other values ​​between 35° and 45°, which are not limited here.

[0044] The included angle β between the second inclined surface 132 and the horizontal plane may satisfy:

[0045] 20°≤β≤25°.

[0046] Among them, the value range of the angle β between the second inclined plane 132 and the horizontal plane is [20°, 25°]. For example, the angle α between the second inclined plane 132 and the horizontal plane can be 20°, 21°, 22°, 23°, 24°, 25° or other values ​​between 20°-25°, which is not limited here.

[0047] By limiting the angle of the first bevel 131 and the second bevel 132, the angle of the bevel 13 is neither too large to affect the supporting strength nor too small to affect the positioning effect of the steel coil 2. The steel coil 2 of the corresponding diameter size can be supported on the corresponding bevel 13 and can be effectively positioned when supported on the corresponding bevel 13.

[0048] According to some embodiments of the present application, Figure 1-Figure 3 As shown, the upper surface 11 of the steel coil saddle 1 is a plane extending in the horizontal direction, and one end of the upper surface 11 is connected to the upper end of the inclined surface 13 located at the uppermost end.

[0049] In this embodiment, the upper surface 11 of the steel coil saddle 1 is a plane extending in the horizontal direction to facilitate the storage and stacking of the steel coil saddle 1, wherein one end of the upper surface 11 facing the other steel coil saddle 1 is connected to the upper end of the inclined surface 13 located at the uppermost end. When the diameter of the steel coil 2 is greater than a certain threshold, the fulcrum of the steel coil 2 is located at the junction of the upper surface 11 and the inclined surface 13, which is also the widest fulcrum under the current assembly conditions. At this position, not only is the fulcrum width larger, but the contact area between the steel coil 2 and the steel coil saddle 1 is reduced, which may reduce the friction coefficient and thus facilitate alignment.

[0050] In some embodiments, the upper surface 11 of the steel coil saddle 1 can be set as an upwardly arched arc surface, one end of the arc surface is connected to the upper end of the inclined surface 13 located at the uppermost end. By setting the arc surface, the positioning effect can be improved when the steel coil 2 is placed on the steel coil saddle 1.

[0051] According to some embodiments of the present application, Figure 1-Figure 3 As shown, the lower surface 12 of the steel coil saddle 1 can be set as a plane extending in the horizontal direction, one end of the lower surface 12 can be spaced apart from the lower end of the inclined surface 13 located at the lowest end, and a connecting surface 14 extending in the up and down direction can be provided between the lower surface 12 and the lower end of the inclined surface 13 located at the lowest end.

[0052] In this embodiment, by setting the lower surface 12 of the steel coil saddle 1 as a plane setting along the horizontal direction, it is convenient to assemble the steel coil saddle 1 on the walking beam, and ensure the accuracy of the inclination angle of the inclined surface 13. Among them, one end of the lower surface 12 facing the inclined surface 13 can be spaced from the lower end of the inclined surface 13 at the lowest end, and connected through the connecting surface 14 to increase the thickness between the lower surface 12 and the inclined surface 13, thereby improving the structural strength of the corresponding position and reducing the probability of the steel coil 2 compressing the steel coil saddle 1.

[0053] According to some embodiments of the present application, Figure 1-Figure 3 As shown, the lower surface 12 of the steel coil saddle 1 may be provided with a plurality of positioning pins 121 extending away from the steel coil saddle 1 .

[0054] In this embodiment, the lower surface 12 of the steel coil saddle 1 can be provided with a positioning pin 121, which extends in a direction away from the steel coil saddle 1 and is used to extend into the positioning groove of the stepping beam for positioning. There can be multiple positioning pins 121, and the multiple positioning pins 121 can be spaced apart along the length direction of the steel coil saddle 1. By providing multiple positioning pins 121, the convenience of positioning and installation is improved, and the assembly strength of the steel coil saddle 1 and the stepping beam can be improved.

[0055] It should be noted that the number of the positioning pins 121 is not specifically limited. Figure 1 and Figure 2 In the embodiment, two positioning pins 121 are provided. In another example, three, four or more positioning pins 121 may be provided, depending on the size of the steel coil saddle 1.

[0056] In this embodiment, the locating pin 121 is arranged at a peripheral guide circle at one end away from the steel coil saddle 1 so as to facilitate the cooperation between the locating pin 121 and the locating groove.

[0057] According to some embodiments of the present application, Figure 1-Figure 3 As shown, the upper surface 11 of the steel coil saddle 1 is provided with a first stepped hole 111, and the first stepped hole 111 is arranged to penetrate the steel coil saddle 1 in the up and down direction. A first bolt is arranged in the first stepped hole 111, and the steel coil saddle 1 is used to be fixedly connected to the stepping beam through the first bolt.

[0058] In this embodiment, a first stepped hole 111 and a first bolt are provided on the upper surface 11 of the steel coil saddle 1 , and the first bolt can pass through the first stepped hole 111 and be fixedly connected to the stepping beam on the lower side of the steel coil saddle 1 to improve the installation strength of the steel coil saddle 1 .

[0059] There may be a plurality of first stepped holes 111 , and the plurality of first stepped holes 111 may be spaced apart along the length direction of the steel coil saddle 1 to further improve the installation stability of the steel coil saddle 1 .

[0060] According to some embodiments of the present application, Figure 1-Figure 3 As shown, the inclined surface 13 at the lower end may be provided with a second stepped hole 133, and the second stepped hole 133 may be arranged through the steel coil saddle 1 in the up and down directions. A second bolt may be provided in the second stepped hole 133, and the steel coil saddle 1 is used to be fixedly connected to the stepping beam through the second bolt.

[0061] In this embodiment, the inclined surface 13 at the lower end may be provided with a second stepped hole 133 and a second bolt, and the second bolt may pass through the second stepped hole 133 and be fixedly connected to the stepping beam at the lower side of the steel coil saddle 1 to improve the installation strength of the steel coil saddle 1.

[0062] There may be a plurality of second stepped holes 133 , and the plurality of second stepped holes 133 may be spaced apart along the length direction of the steel coil saddle 1 to further improve the installation stability of the steel coil saddle 1 .

[0063] It is understandable that the upper end of the second bolt does not extend out of the second stepped hole 133 to avoid interference between the second bolt and the steel coil 2 supported on the surface of the inclined surface 13 .

[0064] In the technical solution of the present application, the first bolt and the second bolt are provided to fix the two sides of the steel coil saddle 1 in the width direction respectively, thereby ensuring the stability of the steel coil 2 when supported on the steel coil saddle 1.

[0065] According to some embodiments of the present application, Figure 1-Figure 3 As shown, the upper surface 11 of the steel coil saddle 1 may be provided with a plurality of lifting holes 112 .

[0066] In this embodiment, the lifting hole 112 can be a threaded hole or a buckle can be provided in the lifting hole 112. The lifting hole 112 can be used to install a lifting part, so that a crane can be connected to the lifting hole 112 to facilitate the installation and removal of the steel coil saddle 1.

[0067] It should be noted that the number of lifting holes 112 is not limited here. In one example, there are two lifting holes 112, and the two lifting holes 112 are spaced apart along the length direction of the steel coil saddle 1. In another example, the lifting holes 112 can be three, four or more than four, which is not limited here.

[0068] In this embodiment, the hoisting hole 112 can be provided in the middle portion of the steel coil saddle 1 in the width direction to improve the stability during hoisting and facilitate assembly and disassembly.

[0069] According to some embodiments of the present application, Figure 2 and Figure 3 As shown, the distance W between the two steel coil saddles 1 can meet the following requirements:

[0070] 45cm≤W≤50cm.

[0071] In this embodiment, the distance between the two steel coil saddles 1 is limited so that the two steel coil saddles 1 can be adapted to the existing steel coils 2 of different diameters after being assembled, so that the distance is not too small to affect the support and positioning effects, and the distance is not too large to make some small-sized steel coils 2 unusable. The steel coils 2 of corresponding diameter sizes can be supported on the corresponding inclined surfaces 13 and can be effectively positioned when supported on the corresponding inclined surfaces 13.

[0072] It should be noted that the distance between the two steel coil saddles 1 is also the distance between the two connecting surfaces 14 .

[0073] Among them, the distance W between the two steel coil saddles 1 has a value range of [45cm, 50cm]. For example, W can be 45cm, 46cm, 47cm, 48cm, 49cm, 50cm or other values ​​between 45cm-50cm, which are not limited here.
