Description

Technical Field

[0001] This application relates to the field of silicon steel coil storage technology, and more specifically, to a silicon steel coil support base. Background Technology

[0002] Silicon steel coils, as an important industrial material, are typically handled by lying flat during storage and transportation. This facilitates lifting and transfer, and optimizes space utilization and operational efficiency. However, in existing technologies, the outer curved surface of silicon steel coils is prone to deformation or damage due to uneven support when lying flat, a problem that has not yet been effectively solved. This uneven support can not only compromise the structural integrity of the coil but also adversely affect its subsequent performance. To address this issue, some existing practices involve designing customized placement platforms for storing silicon steel coils. However, this customized solution has significant limitations: different sizes of silicon steel coils require the design and manufacture of different sized placement platforms. This not only significantly increases manufacturing costs but also leads to equipment redundancy and resource waste, failing to achieve universal adaptability and effective support for silicon steel coils of different sizes.

[0003] There is currently no effective technical solution to the above problems. Utility Model Content

[0005] This application provides a silicon steel coil support base for supporting silicon steel coils, comprising: a base, two first supports and multiple second supports. The first supports and the second supports are both semi-cylindrical. The top surface of the base is provided with two first arc-shaped grooves.

[0025] Please refer to Figures 1-3 This application provides a silicon steel coil support base 1 for supporting silicon steel coils, including: a base 1, two first supports 2 and multiple second supports 3. The first supports 2 and the second supports 3 are both semi-cylindrical. The top surface of the base 1 is provided with two first arc-shaped grooves 11. The two first supports 2 are respectively disposed on the two first arc-shaped grooves 11. The curved surface of the first support 2 is in contact with the first arc-shaped grooves 11 and can be deflected relative to each other. The top surface of the first support 2 is provided with multiple second arc-shaped grooves 21. The extension direction of the second arc-shaped grooves 21 is parallel to the extension direction of the first arc-shaped grooves 11. At least one second arc-shaped groove 21 on each first support 2 is provided with a second support 3. The curved surface of the second support 3 is in contact with the second arc-shaped groove 21 and can be deflected relative to each other.

[0026] Specifically, semi-cylindrical refers to a support with a semi-circular cross-section, which can be achieved by using a solid or hollow semi-cylindrical body, for example, through casting, extrusion or machining.

[0027] More specifically, the fact that the curved surface of the first support 2 is in contact with the first arc groove 11 and can be relatively deflected means that the semi-cylindrical outer surface of the first support 2 is in close contact with the inner surface of the first arc groove 11 on the base 1, and the first support 2 can rotate freely around its axis within the first arc groove 11. This can be achieved by using a smooth contact surface design or by setting a low-friction material between the contact surfaces, such as a polytetrafluoroethylene gasket or a lubricating coating, so that the first support 2 can adjust its angle according to the overall outer diameter and placement posture of the silicon steel coil, thereby achieving preliminary adaptive support.

[0028] More specifically, the fact that the curved surface of the second support 3 is in contact with the second arc-shaped groove 21 and can be relatively deflected means that the semi-cylindrical outer surface of the second support 3 is in close contact with the inner surface of the second arc-shaped groove 21 on the top surface of the first support 2, and the second support 3 can rotate freely within the second arc-shaped groove 21 around its axis. This allows the second support 3 to adjust its angle more precisely to adapt to the local curved surface of the outer periphery of the silicon steel coil, providing more accurate fit support. When the silicon steel coil is laid on the silicon steel coil bearing base 1, the second support 3 can automatically adjust its position and angle, thereby forming multiple dispersed, closely contacting support areas on the outer periphery of the silicon steel coil. Thus, multiple second supports 3 constitute multiple support points that fit on the outer periphery of the silicon steel coil to support the silicon steel coil, effectively distributing the weight of the silicon steel coil, avoiding local stress concentration, and thus preventing deformation or damage to the curved surface of the outer periphery of the silicon steel coil.

[0029] Specifically, the base 1, serving as the foundation of the entire support system, has two first arc-shaped grooves 11 on its top surface providing a stable mounting position for the upper structure. Two first supports 2, in a semi-cylindrical shape, are respectively positioned within these first arc-shaped grooves 11, their curved surfaces closely fitting the grooves and possessing relative deflection capability. This deflection capability allows the first supports 2 to make initial posture adjustments based on the overall size and placement angle of the silicon steel coil. Furthermore, each first support 2 has multiple second arc-shaped grooves 21 on its top surface, extending parallel to the first arc-shaped grooves 11, ensuring the continuity of the support. Within these second arc-shaped grooves 21, multiple second supports 3, also in a semi-cylindrical shape, are positioned. The curved surfaces of the second supports 3 fit the second arc-shaped grooves 21 and also possess relative deflection capability. When the silicon steel coil is placed on these second supports 3, the weight of the silicon steel coil and its outer circumferential curved surface drive the first supports 2 and second supports 3 to automatically deflect within their respective arc-shaped grooves. This dual-layer, multi-point deflection mechanism allows the support to dynamically adapt to the outer contour of the silicon steel coil, forming multiple support points that closely fit the outer circumference of the coil. In this way, the weight of the silicon steel coil is evenly distributed across multiple support points, avoiding excessive localized stress and effectively preventing deformation or damage to the outer curved surface of the coil. Furthermore, due to this adaptability, the base 1 is compatible with silicon steel coils of different outer diameters, eliminating the need for customized designs for each size.

[0030] The silicon steel coil support base 1 of this application introduces a layered and deflectable semi-cylindrical support structure, namely, the first support 2 deflects within the first arc groove 11 and the second support 3 deflects within the second arc groove 21, thereby realizing automatic, multi-point, and precise fitting support for the outer periphery of silicon steel coils of different sizes. This effectively solves the problem of deformation and damage to the outer curved surface of silicon steel coils when they are laid flat due to uneven support, and avoids the manufacturing costs and equipment redundancy caused by customizing placement platforms for silicon steel coils of different sizes.

[0031] In some preferred embodiments, the diameter of the curved surface of the first support 2 is 2.5-2.8 times the diameter of the curved surface of the second support 3.

[0032] Specifically, this application sets the curved surface diameter of the first support 2 to 2.5-2.8 times that of the curved surface diameter of the second support 3. This ensures that the first support 2, as a larger and more fundamental support unit in the load-bearing hierarchy, can provide a stable and moderately supportive platform for the second support 3, which deflects upon it. This specific dimensional ratio allows the first support 2 and the second support 3 to form a good fit, jointly achieving precise, multi-point contact support for the outer periphery of the silicon steel coil. When the silicon steel coil is placed on the second support 3, the first support 2 and the second support 3 can deflect more effectively and automatically, allowing the multiple support points formed by the second support 3 to fit more tightly and evenly against the outer periphery of the silicon steel coil. This combination of structure and size effectively disperses the load, avoids deformation or damage to the outer periphery of the silicon steel coil caused by localized stress concentration, and significantly improves the stability of the load-bearing capacity and the protection of the silicon steel coil.

[0033] In some preferred embodiments, the diameter of the curved surface of the first support 2 is 2.5-2.8 times the maximum depth of the first arc groove 11, and the diameter of the curved surface of the second support 3 is 2.0-2.3 times the maximum depth of the second arc groove 21.

[0034] Specifically, by setting the curved surface diameter of the first support 2 to 2.5-2.8 times the maximum depth of the first arc-shaped groove 11, the embedding depth and deflection angle of the first support 2 are optimized when it moves within the groove. This allows the first support 2 to tilt and adjust according to the overall outer circumferential curvature of the silicon steel coil. This geometric relationship avoids instability or restricted deflection caused by improper fit between the first support 2 and the base 1, thus achieving initial adaptive support for the silicon steel coil at the first level.

[0035] In some preferred embodiments, the distance between the centerlines of the two curved surfaces of the first support 2 is 2.1-2.2 times the diameter of the curved surface of the first support 2.

[0036] Specifically, this scheme establishes a proportional relationship based on the dimensions of the first supports 2 to determine their spacing by limiting the distance between the centerlines of the curved surfaces of the two first supports 2 to 2.1-2.2 times the diameter of the curved surface of the first support 2. This proportional relationship ensures that the spacing between them can be optimized regardless of the absolute dimensions of the first supports 2. When the silicon steel coil is placed on the bearing base 1, this set centerline distance allows the two first supports 2 to initially support the silicon steel coil in a stable posture, forming a stable "V"-shaped support structure. This initial stable support allows the weight of the silicon steel coil to be evenly distributed on the two first supports 2, avoiding local stress concentration. As a result, since the silicon steel coil obtains uniform and stable initial support, the automatic deflection mechanism of the first supports 2 and the second supports 3 can be fully utilized. The first supports 2 and the second supports 3 can deflect and fit around the outer circumferential curved surface of the silicon steel coil more smoothly and effectively, further increasing the support points and allowing the pressure on the outer circumference of the silicon steel coil to be more widely distributed.

[0037] In some preferred embodiments, each first support 2 is provided with two second arc-shaped grooves 21, and each second arc-shaped groove 21 is provided with a second support 3.

[0038] Specifically, this solution optimizes the support structure of the silicon steel coil by explicitly limiting the number of second arc-shaped grooves 21 and second supports 3 on each first support 2, thereby providing a more stable and uniform load-bearing effect and effectively solving the problem of localized pressure deformation or damage to the outer periphery of the silicon steel coil. Each first support 2 is provided with two second arc-shaped grooves 21, ensuring that each first support 2 has at least two preset positions for installing the second support 3. Furthermore, each second arc-shaped groove 21 is equipped with a second support 3, meaning that both second arc-shaped grooves 21 on each first support 2 are fully utilized, each supporting one second support 3. In this way, each first support 2 can provide two independent, deflectable support points. Compared to cases with only one second support 3 or an uncertain number of second supports 3, this dual-point support structure significantly increases the contact area between the silicon steel coil and the bearing base 1, as well as the number of support points. More support points can more precisely conform to the outer peripheral curved surface of the silicon steel coil, distributing the weight of the silicon steel coil more evenly across multiple support points. This scheme, combined with the deflection adaptability of the first support 2 and the second support 3, enables the entire load-bearing system to dynamically adjust according to the outer circumferential surface of the silicon steel coil. This ensures that with a fixed number and distribution of support points, each support point can effectively fit and share the load, thereby avoiding local stress concentration and improving the overall load-bearing stability and reliability.

[0039] In some preferred embodiments, the distance between the centerlines of the curved surfaces of the two second supports 3 on each first support 2 is 2.5-2.8 times the diameter of the curved surface of the second support 3.

[0040] Specifically, this precise proportional relationship, combined with the automatic deflection function of the first support 2 and the second support 3, enables the two second supports 3 to form an optimal distribution of support points when carrying the silicon steel coil. When the silicon steel coil is placed on the second support 3, this optimized spacing ensures that the two second supports 3 form effective and dispersed contact points on the outer periphery of the silicon steel coil. This avoids the problems of excessive local stress due to overly concentrated support points or insufficient support due to overly dispersed support points. In this way, the weight of the silicon steel coil can be more evenly distributed across multiple support points, thereby effectively reducing the risk of deformation or damage to the outer curved surface of the silicon steel coil and improving the structural integrity and stability of the silicon steel coil during storage and transportation.

[0041] In some preferred embodiments, the two second arcuate grooves 21 on each first support 2 are symmetrically arranged based on the axis of the curved surface of the first support 2.

[0042] Specifically, this application ensures that the distribution of the second supports 3 on the first supports 2 is balanced and uniform by symmetrically arranging the two second arc-shaped grooves 21 on each first support 2 based on the axis of the curved surface of the first support 2. When the silicon steel coil is laid on the second supports 3, the weight of the silicon steel coil can be evenly transferred to the first support 2 due to the symmetrical layout of the second supports 3, avoiding local stress concentration caused by uneven distribution of support points. This symmetrical arrangement allows the two second supports 3 supported by the first support 2 to fit against the outer periphery of the silicon steel coil in a balanced manner when the first support 2 deflects to adapt to the outer periphery of the silicon steel coil, thereby forming more stable and uniform multiple support points. This structural combination fully utilizes the automatic deflection adaptability of the first support 2 and the second support 3, ensuring that the supporting force on the outer curved surface of the silicon steel coil is evenly distributed, thereby enhancing the stability of the silicon steel coil under load and minimizing the risk of deformation or damage to the outer curved surface of the silicon steel coil due to uneven support.

[0043] In some preferred embodiments, the length of the second support 3 is greater than the length of the silicon steel coil.

[0044] Specifically, the lengths of the first support 2 and the base 1 are preferably equal to the length of the second support 3.

[0045] Specifically, the length of the second support 3 is designed to be greater than the length of the silicon steel coil, ensuring that the second support 3, which directly contacts the outer periphery of the silicon steel coil, can completely cover and exceed the overall length of the silicon steel coil in the axial direction. This design allows the entire axial range of the silicon steel coil to receive continuous and uniform support, avoiding sagging, deformation, or localized stress concentration that may occur at the ends of the silicon steel coil due to lack of support. Simultaneously, the lengths of the first support 2 and the base 1 are equal to the length of the second support 3. This feature ensures that the first support 2, as the lower support structure, and the bottom base 1 can provide complete and uniform support for the upper second support 3. Since the length of the second support 3 is designed to be greater than the length of the silicon steel coil to achieve comprehensive axial support, the first support 2 and the base 1 below it must also have the same length to ensure that every part of the second support 3 can bear sufficient load. This layered length matching, combined with the design of the silicon steel coil support base 1 (including base 1, two first supports 2, and multiple second supports 3), which automatically deflects the first supports 2 and second supports 3 to fit the outer circumference of the silicon steel coil, thus forming multiple support points that fit the outer circumference of the silicon steel coil, constructs a stable and reliable support system in both the axial and radial directions. When the silicon steel coil is laid flat, not only can its outer curved surface be adaptively supported by the deflection of the supports, but its axial ends are also fully covered by the extra-long design of the second supports 3. At the same time, the consistent length of the entire support structure (second supports 3, first supports 2, and base 1) ensures effective load transfer and overall system stability. This combination allows the silicon steel coil to be fully protected during storage and transportation, effectively preventing structural instability or local failure caused by uneven support, thereby significantly improving the structural integrity of the silicon steel coil and the overall performance of the support base 1.

[0046] In some preferred embodiments, the distance between the centerlines of the curved surfaces of the two first supports 2 is 0.45-0.85 times the outer diameter of the silicon steel coil.

[0047] Specifically, this application ensures that the silicon steel coil, when placed on the bearing base 1, can be supported by the two first supports 2 at an initial angle and position by limiting the distance between the centerlines of the curved surfaces of the two first supports 2 to 0.45-0.85 times the outer diameter of the silicon steel coil. As long as the outer diameter of the silicon steel coil meets this proportional range, it can be stably placed on the first supports 2. This structural configuration allows the adaptive deflection mechanism of the first supports 2 and the second supports 3 to function more effectively, avoiding instability or excessive local stress caused by improper initial support positions. In this way, the bearing base 1 can provide stable and uniform support for silicon steel coils of different sizes, effectively protecting the outer curved surface of the silicon steel coil and improving the versatility and adaptability of the bearing base 1.

[0048] In some preferred embodiments, the first arcuate groove 11 and the second arcuate groove 21 are coated with lubricant.

[0049] Specifically, this solution addresses the friction problem during support deflection by applying lubricant to the first arc-shaped groove 11 and the second arc-shaped groove 21, based on the silicon steel coil support base 1. By coating the contact surfaces of the first arc-shaped groove 11 and the second arc-shaped groove 21 with lubricant, this application reduces the frictional resistance of the first support 2 in the first arc-shaped groove 11 and the second support 3 in the second arc-shaped groove 21 during deflection. This reduction in friction allows the first support 2 and the second support 3 to automatically deflect and conform to the placement of the silicon steel coil. Consequently, the second support 3 can form multiple conforming support points, distributing the weight of the silicon steel coil and preventing localized stress concentration. Furthermore, the introduction of lubricant reduces wear between the arc-shaped grooves and the supports, thereby extending the service life of the entire support base 1. Therefore, the application of lubricant enables the automatic adaptation function of the support base 1 and improves its durability.
