Description

Technical Field

[0001] This utility model belongs to the field of transformer manufacturing technology, specifically relating to a silicon steel sheet support rack. Background Technology

[0002] After being cut and shaped during transformer manufacturing, silicon steel sheets are typically placed on special material plates for transfer and temporary storage. Due to the large demand for mass production, a single material plate can support silicon steel sheets weighing up to 3 tons, with dimensions usually exceeding 3200mm × 800mm, classifying them as large-size and heavy materials.

[0003] During the production process, silicon steel sheets need to be stored and rotated efficiently in a limited space. However, the existing method of placing silicon steel sheets directly on the ground has problems such as large space occupation, low handling efficiency, poor storage stability, and space limitations.

[0004] Large space occupation: When the material plates are laid flat or stored in a single layer, they occupy a large area, resulting in low storage density in workshops or warehouses and low space utilization.

[0005] Low handling efficiency: The material plates are heavy and difficult to handle manually, relying on equipment such as forklifts, but it is inconvenient to pick up and put down when stacking multiple layers; Poor storage stability: Ordinary shelving or stacking methods lack targeted support structures, and simple stacking of pallets poses a risk of tipping over, resulting in poor safety.

[0006] Site limitations: During peak production periods, the turnover of material plates is large, and traditional storage methods cannot meet the demand for efficient temporary storage, leading to logistics congestion. Utility Model Content

[0007] This utility model provides a silicon steel sheet material rack, which solves the technical problem of limited storage space and poor storage stability of silicon steel sheet materials when cutting silicon steel sheets in batches.

[0008] To achieve the above objectives, the silicon steel sheet support rack of this utility model includes at least two frame bodies, each frame body comprising: Two supporting legs; The first crossbeam is fixed to the bottom of the two support legs; The second crossbeam is detachably installed in the middle of the support leg; A third crossbeam, with one end rotatably mounted on the top of a support leg via a pivot, and the other end detachably connected to another support leg; A limiting block welded to the outside of one side of the support leg is disposed on the same side as the rotating shaft; The hanging bracket is welded to the outside of the support leg.

[0009] Furthermore, the rotating shaft includes a bolt, a nut, and a flat washer; the bolt passes through the shaft hole of the support leg and the shaft hole at the end of the third crossbeam, and the nut is tightened and welded to the bolt for fixation.

[0010] Furthermore, the exposed length of both ends of the bolt is ≤5mm, and the axis is perpendicular to the outer side of the support leg. Furthermore, the short side of the limiting block is horizontally welded to the outside of the support leg, while the long side is tilted downwards at 45° to 60°.

[0011] Furthermore, both ends of the second crossbeam are provided with inverted L-shaped buckles, and the middle of the support leg has a T-shaped slot that matches the buckles.

[0012] Furthermore, the T-shaped slot is fitted with a wear-resistant bushing.

[0013] Furthermore, the support legs are made of cold-rolled hollow square steel.

[0014] Furthermore, bottom reinforcing ribs are welded on both sides at the connection between the first crossbeam and the support leg, and the bottom reinforcing ribs are right-angled triangular steel plates.

[0015] Furthermore, a base plate is welded to the bottom of the support leg.

[0016] Furthermore, the upper surfaces of the first, second, and third crossbeams are all provided with anti-slip textures.

[0017] Compared with the prior art, the present invention has at least the following beneficial technical effects: 1) Space utilization has been significantly improved The three-layer vertical storage structure increases the utilization rate of warehouse space by more than 200% compared to the traditional single-layer flat method. The modular design allows the distance and orientation between the shelves to be adjusted according to the actual situation, making the shelving units flexible to be arranged according to site conditions. This is especially suitable for production transition sites with limited space.

[0018] 2) Operational ease of use has been greatly improved. The rotatable upper layer design and detachable middle layer structure enable independent access to each layer; the lifting design complies with national standards and facilitates operation with lifting equipment.

[0019] 3) Outstanding heavy load-bearing capacity The all-steel welded structure can bear up to 3.5 tons per layer and more than 10 tons for the whole frame. The reinforcing ribs on both sides of the bottom of the support legs form a triangular support system, which, together with the horizontal reinforcement structure formed by the bottom crossbeam, increases the bending stiffness of the frame by 40%. The first crossbeam at the bottom and the support legs adopt a full welding process to ensure the stability of the foundation load.

[0020] 4) Excellent material protection effect The anti-slip design and limiting device on the contact surface ensure that the upper crossbeam is stable and reliable.

[0021] 5) Stable and reliable structure The rotating shaft mechanism adopts a double anti-loosening design of bolt welding and nut to ensure reliability under high load; The limit block is made of angle steel and can withstand lateral impact forces of over 500N.

[0022] The spacing between the support legs is optimized based on the width of the material plate, which can control the mid-span deflection to within 1 / 500.

[0023] 6) Excellent maintenance and expansion capabilities The modular frame design allows for independent assembly and disassembly, reducing equipment conversion costs by 60%; the standardized component design simplifies maintenance and replacement, extending service life by 30%.

[0024] This application successfully solves industry problems such as low space utilization, inconvenient operation, and low transfer efficiency in the storage of silicon steel sheets and plates. Practical application shows that this shelving unit can more than double the storage capacity, significantly improve storage efficiency, and is safe and reliable, with significant economic benefits and promotional value. Its simple and reliable structure, ease of manufacturing, and wide applicability make it particularly suitable for large-scale applications in manufacturing enterprises. Attached Figure Description
