Description

Technical Field

[0001] This utility model relates to the field of connecting plate technology, and in particular to a crane connecting plate. Background Technology

[0002] In steel plants, cranes and gantry cranes are numerous, undertaking the task of transporting a huge amount of steel billets and molten steel each year. For many years, the crane connecting plates have used ordinary plate pin connections. This connection method has many problems, the most prominent being the rapid wear of the connecting plates, which leads to frequent replacements. When the wear of the connecting plates exceeds their load-bearing capacity, they are prone to breakage, causing the cast billets and steel billets to fall, creating a serious safety risk and affecting the normal operation of the cranes. Utility Model Content

[0003] The purpose of this utility model is to provide a crane connection plate that can solve the above-mentioned technical problems.

[0004] This utility model provides a crane connecting plate, including a connecting plate body. The overall shape of the connecting plate body is a ring structure. Arc-shaped guard plates are symmetrically fixed on both sides of the connecting plate body. The thickness of the arc-shaped guard plates is 0.6-0.8 times the thickness of the connecting plate body.

[0005] Furthermore, the connecting plate body and the arc-shaped guard plate are connected by welding.

[0006] Furthermore, the surface of the connecting plate body is provided with shallow groove-shaped reinforcing ribs in a crisscross pattern.

[0007] Furthermore, the shallow groove of the shallow groove-shaped reinforcing rib has a depth of 2-5 mm, a width of 5-15 mm, and a spacing of 20-50 mm between adjacent reinforcing ribs.

[0008] Shallow grooved reinforcing ribs are located on the surface of the connecting plate, distributed in a crisscross pattern. Their depth is 2-5mm, a design choice that balances adding minimal weight with ensuring structural strength enhancement. The width is 5-15mm; this appropriate width effectively enhances the ribs' load-bearing capacity and stress dispersion. The spacing between adjacent reinforcing ribs is 20-50mm, creating a reasonable mechanical support network across the entire connecting plate surface. The shallow grooved reinforcing ribs are an integral part of the connecting plate body. When the connecting plate is subjected to complex loads such as tension, compression, and shear, these ribs alter the force transmission path, distributing concentrated forces over a larger area, thereby improving the overall structural strength of the connecting plate and effectively resisting various forces generated during crane operation, preventing deformation and cracking. Simultaneously, the shallow grooved reinforcing ribs also contribute to improving the wear resistance of the connecting plate to some extent, as they alter the surface structure and stress distribution, reducing the possibility of localized wear.

[0009] Furthermore, the surface of the connecting plate body is provided with a nickel plating layer.

[0010] Furthermore, the thickness of the nickel plating layer is 5-15 μm.

[0011] Furthermore, a superhard carbon coating with a thickness of 1-5 μm is deposited on the surface of the nickel plating layer using physical vapor deposition (PVD) technology.

[0012] Furthermore, the superhard carbon coating is a diamond-like carbon (DLC) coating.

[0013] The curved guard plate can also be fitted with a nickel plating layer and an ultra-hard carbon coating, depending on the application requirements.

[0014] Furthermore, the yield strength of the connecting plate body is not less than 500 MPa, and the tensile strength is not less than 700 MPa.

[0015] Furthermore, the connecting plate body is made of ZGMn13 material.

[0016] Beneficial effects:

[0017] This invention effectively prevents breakage due to wear exceeding the load-bearing capacity by symmetrically fixing arc-shaped protective plates on both sides of the connecting plate body. It eliminates the safety hazard of billets and steel slabs falling, ensuring the safety of on-site operators and preventing production stoppages and huge economic losses caused by safety accidents. It also ensures the safe and stable operation of the crane and the transfer car during the transportation of billets and molten steel. By solving the problem of connecting plate wear and breakage, it avoids the impact of these failures on the normal use of the crane. The crane can maintain a stable working state, reducing sudden malfunctions and repairs caused by connecting plate problems, improving the crane's availability, and contributing to the efficient production operation of the steel plant.

[0027] Example 1

[0028] A crane connection plate, such as Figure 1 As shown, it includes a connecting plate 1 body, the overall shape of which is a ring structure, as... Figure 2 As shown, the connecting plate body 1 in this embodiment is elliptical in shape. Arc-shaped guard plates 2 are symmetrically fixed on both ends of the connecting plate body 1. The connecting plate body 1 and the arc-shaped guard plates 2 are connected by welding. The thickness of the arc-shaped guard plates 2 is 0.6-0.8 times the thickness of the connecting plate body 1.

[0029] The surface of the connecting plate body 1 is crisscrossed with shallow groove-shaped reinforcing ribs. The groove depth of the shallow groove-shaped reinforcing ribs is 2-5mm, the width is 5-15mm, and the spacing between adjacent reinforcing ribs is 20-50mm (not shown in the figure due to their small size and density). The shallow groove-shaped reinforcing ribs are a key part of the crane connecting plate structural design. They are rib structures of a specific shape machined into the surface of the connecting plate, in the form of shallow grooves. This design is based on mechanical principles and aims to improve the performance of the connecting plate under complex loads. When the crane is working, the connecting plate is subjected to forces of various directions and types. The shallow groove-shaped reinforcing ribs redistribute stress by changing the local structure of the connecting plate, thereby enhancing the overall strength of the connecting plate. The depth is designed to be 2-5mm, a relatively shallow depth that ensures effective force distribution without significantly increasing the weight of the connecting plate. The width is set at 5-15mm, a width range that allows the reinforcing ribs to have sufficient load-bearing capacity under pressure and tension, and to better resist external forces. The spacing between adjacent reinforcing ribs is 20-50mm. This spacing arrangement creates a reasonable mechanical support network on the surface of the connecting plate, ensuring that the force is evenly distributed across the entire connecting plate and avoiding stress concentration. During crane operation, the connecting plate is subjected to forces including tensile, compressive, and shear forces. The shallow grooved reinforcing ribs can disperse these complex external forces. For example, when subjected to tensile force, the reinforcing ribs act like small "dams," preventing crack propagation and distributing the tensile force over a larger area, thereby improving the connecting plate's resistance to tensile failure. When subjected to compressive force, the reinforcing ribs increase the local compressive strength of the connecting plate, preventing local deformation caused by excessive pressure. For shear force, the shallow grooved reinforcing ribs alter the force transmission path, causing the shear force to be decomposed and redistributed as it passes through the reinforcing ribs, reducing the risk of connecting plate failure due to shear action.

[0030] like Figure 4 As shown, the surface of the connecting plate body is provided with a nickel plating layer 3, the thickness of which is 5-15μm. A superhard carbon coating 4 with a thickness of 1-5μm is deposited on the surface of the nickel plating layer 3 using physical vapor deposition (PVD) technology. The superhard carbon coating 4 is a diamond-like carbon (DLC) coating.

[0031] The connecting plate body has a yield strength of not less than 500 MPa and a tensile strength of not less than 700 MPa. The connecting plate is made of ZGMn13 material.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.

Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
