Description

Technical Field

[0001] This utility model relates to the field of I-beam wheel technology, specifically to a high-strength I-beam wheel. Background Technology

[0002] During the production of I-beam reels, their weight cannot be too heavy, so the end plates and reinforcing rib cavities cannot be too thick. This leads to deformation of the I-beam reel after assembly and shaping. Even after being delivered and put into use, the I-beam reel is prone to deformation due to insufficient strength when fully wound with rope or wire. Therefore, it is crucial to address the deformation problem caused by insufficient strength during the I-beam reel production process to prevent subsequent issues such as reel bulging and cracking, which could affect production. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a high-strength I-beam wheel that eliminates deformation during the forming process and prevents issues such as wheel expansion and cracking after use, thereby enhancing the strength of the I-beam wheel.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A high-strength H-beam wheel includes an end plate, a rim connected to the outer edge of the end plate, an outer cylinder connected to both ends of the end plate, an inner tube located within the inner cavity of the outer cylinder, and a plurality of connecting screws, characterized in that...

[0006] Several reinforcing rib cavities are evenly distributed circumferentially on the upper surface of the end plate and are radially distributed around the axis of the I-beam wheel. Each reinforcing rib cavity is a cavity that protrudes upward along the upper surface of the end plate.

[0007] Several folded plate reinforcing ribs are fixed in the reinforcing rib cavity;

[0008] The fasteners are located at both ends of the inner tube and are fixedly connected to the end plates at the axis of the I-beam wheel;

[0009] Several inner supports are provided, one end of which is fixedly connected to the inner wall of the outer cylinder, and the other end of which is close to the outer surface of the fixing member.

[0010] In some embodiments, the connecting screw passes through the outer cylinder and the end plate and is fixed by fasteners, with the connecting screw close to the inner wall of the outer cylinder.

[0011] In some embodiments, the connecting screws are evenly distributed along the circumference of the outer cylinder, and their axes are parallel to the axis of the I-beam wheel.

[0012] In some embodiments, the folded plate reinforcing rib is a plate-shaped structure with a predetermined bending angle, and the bending height of the folded plate reinforcing rib matches the height of the reinforcing rib cavity.

[0013] In some embodiments, the folded plate reinforcing rib includes a bottom surface and several side surfaces connected to the bottom surface, with the bottom surface and the side surfaces forming an angle.

[0014] In some embodiments, the folding plate reinforcing rib is made of steel plate.

[0015] In some embodiments, the number of reinforcing rib cavities is 6-12, and the number of folded plate reinforcing ribs is not greater than the number of reinforcing rib cavities.

[0016] In some embodiments, the rim is a rolled structure, and the outer wall of the rim forms a continuous line contact with the outer wall of the end plate.

[0017] In some embodiments, pin tubes are evenly distributed along the outer edge of the fastener.

[0018] Beneficial effects:

[0019] (1) The steel plate used in this utility model is not thick, but it is strong, durable, economical and practical. The wheel rim is rolled round, and the reinforcing rib cavity is punched with several protruding cavities from the inside to the outside. The end plate and the reinforcing rib cavity are welded evenly by spot welding, which saves time and has sufficient strength. By using several folded plate reinforcing ribs, the fatigue situation of the end plate directly bearing the force can be decomposed.

[0020] (2) The inner tube and the outer cylinder of this utility model are supported by an inner support. The inner support is located near the outer end of the outer cylinder, which greatly reduces the problem of wheel expansion when the wheel is full. The connecting screw is evenly distributed and close to the outer cylinder, which also avoids the problem of wheel expansion. After practical testing, no deformation occurred during the shaping process of the I-beam wheel. After use, there are no more problems such as wheel expansion or cracking. The strength of the I-beam wheel is improved, the deformation problem of the I-beam wheel is solved, and the scrap rate of the I-beam wheel is reduced. Attached Figure Description

[0025] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0027] like Figures 1 to 3 The high-strength H-beam wheel shown includes an end plate 4, a wheel rim 2 connected to the outer edge of the end plate 4, an outer cylinder 8 connected to the end plates 4 at both ends, an inner tube 7 located in the inner cavity of the outer cylinder 8, and several connecting screws 9.

[0028] The reinforcing rib cavities 1 are evenly distributed circumferentially on the upper surface of the end plate 4, and are radially distributed around the axis of the I-beam wheel. The reinforcing rib cavity 1 is a cavity that protrudes upward along the upper surface of the end plate 4 and has a hollow internal structure. The folded plate reinforcing rib 3 is fixed in the reinforcing rib cavity 1. The folded plate reinforcing rib 3 is a plate-shaped structure with a predetermined bending angle. Its bending height matches the height of the reinforcing rib cavity 1, and the bending angle of the folded plate reinforcing rib 3 is 90°. This bending angle can provide a good support effect. The folded plate reinforcing rib 3 is made of bent steel plate with high mechanical properties. The number of reinforcing rib cavities 1 is 6-12, and the number of folded plate reinforcing ribs 3 is not greater than the number of reinforcing rib cavities 1. In use, the reinforcing rib cavity 1 has rounded corners to accommodate the rounded corners.

[0029] The folded plate reinforcing rib 3 includes a bottom surface 31 and several side surfaces 32 connected to the bottom surface 31. An angle is formed between the bottom surface 31 and the side surfaces 32. During use, an angle of 90° achieves better results. At the same time, when fixing, the bottom surface 31 is fixedly connected to the upper surface of the end plate 4, and the top of the side surfaces 32 is fixedly connected to the inner surface of the reinforcing rib cavity 1. The end plate 4 and the reinforcing rib cavity 1 are uniformly welded by spot welding. This saves time and provides sufficient strength. At the same time, by using several folded plate reinforcing ribs 3, the fatigue of the end plate 4 directly bearing the force can be distributed.

[0030] The fasteners 11 are located at both ends of the inner tube 6 and are fixedly connected to the inner end plate of the reinforcing rib cavity 1; one end of the inner support 5 is fixedly connected to the inner wall of the outer cylinder 8, and the other end of the inner support 5 is close to the outer surface of the fasteners 11, or can be fixedly connected to the outer surface of the fasteners 11.

[0031] The connecting screw 9 passes through the outer cylinder 8 and the end plate 4 and is fixed by fasteners 10. The connecting screw 9 is evenly distributed around the outer cylinder 8 and its axis is parallel to the axis of the I-beam wheel. The wheel rim 2 is a rolled structure. The outer wall of the wheel rim 2 forms a continuous line contact with the end plate 4. It can also be rolled by the outer wall of the end plate 4.

[0032] Meanwhile, the high-strength I-beam wheel of this utility model utilizes the mechanical properties of the folded plate reinforcing ribs 3 to decompose the fatigue situation of the end plate 4 directly subjected to force. Two fixing parts 11 are welded to both ends of the inner tube 7 respectively, and the two ends of several inner supports 5 are welded to the inner side of the outer cylinder 8 and the fixing parts 11 respectively. Before the end plate 4 is welded and fixed to the reinforcing rib cavity 1, the folded plate reinforcing ribs 3 are evenly distributed in the reinforcing rib cavity 1. The reinforcing rib cavity 1 is evenly distributed circumferentially on the upper surface of the end plate 4, and is distributed in a circumferential radial pattern with the axis of the I-beam wheel as the center. The bottom surface 31 is fixedly connected to the upper surface of the end plate 4, and the top of the side surface 32 is fixedly connected to the inner surface of the reinforcing rib cavity 1 to support the reinforcing rib cavity 1. Then, the end plate 4 and the reinforcing rib cavity 1 are spot welded together. Several connecting screws 9 are used to connect several welded joints of the reinforcing rib cavity 1 and the end plate 4 to the welded joints of the inner support 5 and the outer cylinder 8. They are locked with fasteners 10 and spot welded together. Several welded joints of the reinforcing rib cavity 1 and the end plate 4 are respectively welded to the ends of the fixing parts 11 to form the I-beam wheel.

[0033] The two sides of the folded plate reinforcing rib 3 are bent at a 90-degree angle. After the reinforcing rib cavity 1, the folded plate reinforcing rib 3, and the end plate 4 are welded, the yield strength test is performed. The yield strength is greater than 300MPa. After the I-beam is formed, the strength is higher than 235MPa.

[0034] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0035] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
