Description

Technical Field

[0001] The utility model belongs to the technical field of high-temperature steel billet transfer equipment, and more specifically relates to a heat dissipation type steel billet support frame. Background Art

[0002] Billet transporters are typically used to transfer billets between different sections of a steel mill. Basic operation involves the transporter arriving at a designated location, using a crane to lift the hot billets onto the transporter's platform. The billets are then transported to another section of the mill for further processing into various steel products. To prevent the billets from falling off the vehicle during transfer, protective devices are often installed on the platform. Furthermore, to prevent the heat radiation from the hot billets from causing deformation of the vehicle frame and potentially causing the transporter to lose its proper performance, existing practices typically incorporate an insulation layer on the platform to minimize damage from this heat.

[0003] However, in actual operation, hot steel billets often come into direct contact with protective devices, which are also affected by the heat radiation from the hot steel billets, resulting in a reduction in their service life and a significant reduction in their safety protection effect. Therefore, it is also very necessary to enhance the thermal radiation resistance of protective devices.

[0004] After searching, patent CN211765151U discloses a flatbed transport vehicle for high-temperature steel billets. The application includes a vehicle body, end walls, and stops. The vehicle body includes a base frame, a refractory brick layer, and a load-bearing beam. The base frame is covered with a refractory brick layer, and a load-bearing beam is arranged above the refractory brick layer. The two ends of the load-bearing beam are respectively connected to the two sides of the base frame. The two ends of the base frame are respectively connected to the end walls, and stops are respectively arranged on both sides of the base frame. In the application, the refractory brick layer designed at the bottom of the vehicle body eliminates damage to the vehicle body caused by high temperature and harm to personnel when lifting and unloading steel billets. In addition, the load-bearing beam is arranged on the refractory brick layer to prevent the steel billets from directly contacting the refractory bricks and causing the refractory bricks to be crushed. At the same time, by arranging stops on both sides of the base frame, the tilting movement of the steel billets during transportation is avoided. However, the problem of the load-bearing beam and the stops themselves being easily damaged by heat radiation has not been effectively solved in this application. Utility Model Content

[0034] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0035] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] The present invention will be further described below in conjunction with specific embodiments.

[0037] like Figure 1-Figure 3 As shown in the figure, a heat-dissipating billet support frame of this embodiment includes a support frame body 1 and protective columns 2 disposed at both ends of the support frame body 1. The top of the support frame body 1 and the facing sides of the protective columns 2 together form a storage space for transported billets. The support frame body 1 is primarily responsible for bearing the weight of the billets, while the protective columns 2 are used to limit the billets from the sides, preventing them from falling off the support frame during transportation.

[0038] To minimize the thermal radiation damage caused by the high-temperature steel billet to the support frame body 1, in this embodiment, a plurality of spacers 3 are spaced along the length of the upper surface of the support frame body 1, forming a heat dissipation channel between adjacent spacers 3. The spacers 3 can be made directly of steel or refractory materials as known in the art. Preferably, the heat dissipation channel is 20-40 mm wide, allowing for sufficient airflow for heat dissipation and sufficient room for thermal expansion and contraction, increasing the overall toughness of the support frame and ensuring a large enough contact surface for more evenly distributed force when supporting cargo. The heat dissipation channel is inclined, with an angle α of 10-45°. This ensures sufficient linear contact length when loading the round billet, distributing the force more evenly, and preventing the round billet from becoming stuck in the heat dissipation channel in extreme cases. (When lifting round billets using a magnetic disk, the billet axis is generally parallel to the vehicle body or within a ±30° range. If it were to become parallel to the heat dissipation channel at any given moment, it could become stuck.) The tilted heat dissipation channel is designed to prevent the round billet from getting stuck in the channel during transportation, which would concentrate the billet's weight on one side of the pad 3 and accelerate damage. Of course, several pads 3 can also be installed at the bottom of the support frame body 1 to further reduce the heat radiation generated by high temperatures to the insulation layer and further enhance the overall elasticity of the support frame. Since the bottom pads 3 do not come into direct contact with the billet, they do not need to be tilted.

[0039] The heat-dissipating billet support frame of this embodiment utilizes the spacer 3 to prevent direct contact between the support frame body 1 and the billet, thereby reducing heat radiation damage. Furthermore, the heat dissipation channels ensure that air is always flowing through the gap between the top of the support frame body 1 and the bottom of the billet, further reducing heat transfer from the billet to the support frame body 1.

[0040] like Figure 4 As shown, the support frame body 1 in this embodiment is made of H-shaped steel. Compared with traditional square billets, H-shaped steel has a lighter weight and can effectively increase the actual loading capacity of the vehicle (the shelf is considered part of the total mass of the cargo during transportation. When the vehicle's rated load mass is fixed, the lighter the shelf, the greater the vehicle's effective cargo capacity). In order to ensure the support strength of the H-shaped steel, a reinforcing bar 4 can be provided in the belly space on both sides of the H-shaped steel. The reinforcing bar 4 can be made of steel plate, which is placed near the outside of the corresponding belly space and then welded. At the same time, a number of ventilation holes can be opened in the steel plate. On the one hand, it can accelerate the circulation of air in the belly space, which is conducive to reducing the heat radiation damage caused by the high-temperature steel billet to the support frame body 1; on the other hand, it is conducive to enhancing the overall toughness of the support frame body 1 to disperse the impact damage caused by the sudden drop of the steel billet during the lifting process. It is worth mentioning that the above-mentioned belly space refers to the area enclosed by the upper and lower flanges of the H-shaped steel and one side of the web.

[0041] As an implementation method of the protective column 2 in this embodiment, refer to Figure 5 As shown, the protective column 2 includes a connecting plate 21 and a support plate 22 vertically welded to the side of the connecting plate 21. The connecting plate 21 is primarily used to connect to the support frame body 1 and can be made of steel plate. The support plate 22 is used to protect the side of the steel billet and can also be made of steel plate.

[0042] Preferably, a weld opening is provided on the connecting plate 21 for the support frame body 1 to pass through. Simultaneously, the lower end surface of the support plate 22 is aligned with the top of the support frame body 1. This design effectively increases the weld area between the connecting plate 21, the support plate 22, and the support frame body 1, thereby ensuring weld strength between the protective column 2 and the support frame body 1 and improving the impact resistance of the protective column 2. Furthermore, the provision of the weld opening ensures that both ends of the H-beam belly space remain unobstructed, which also facilitates heat dissipation.

[0043] Furthermore, the support surface of the support plate 22 can be designed to be flat or curved. It is worth mentioning that the support surface refers to the inner side surface of the support plate 22, that is, the surface in contact with the steel billet. When a flat support surface is used, the end face of the support plate 22 can be directly used as the support surface; when a curved support surface is used, it is necessary to cut an arc-shaped notch on the end face of the support plate 22. Among them, the flat support surface has a wide range of practicality and can be applied to the protection operations of steel billets of various shapes. When transporting round billets, there is a larger contact area between the curved support surface and the round billet, which is conducive to dispersing the impact force when the round billet moves horizontally and preventing stress concentration in local positions.

[0044] refer to Figure 6 As shown in FIG. 1 , as another implementation of a heat dissipation type steel billet support frame of this embodiment, its basic structure is the same as the above-mentioned one, and the main difference lies in the structural form of the protective column 2 .

[0045] Specifically, refer to Figure 7 As shown, the guard column 2 includes, in addition to the connecting plate 21 and the support plate 22, a transition plate 23. The connecting plate 21, the support plate 22, and the transition plate 23 can all be made of steel plates. The connecting plate 21 and the support plate 22 are arranged parallel to each other, facing each other. The ends of the transition plate 23 are welded to the side surfaces of the connecting plate 21 and the support plate 22, respectively, to connect the three into a whole. The advantage of this design is that the supporting surface of the support plate 22 is the side surface of the support plate 22, rather than the end surface. This increases the contact area between the support plate 22 and the steel billet, which helps to optimize the overall force on the support plate 22.

[0046] Preferably, welding openings for the support frame body 1 to pass through can be simultaneously provided at corresponding locations on the connecting plate 21 and the support plate 22. The lower end surface of the transition plate 23 is ensured to be in contact with the top of the support frame body 1, thereby increasing the welding area between the protective column 2 and the support frame body 1 and ensuring weld strength. Of course, the support surface of the support plate 22 in this embodiment can also be a flat surface or a curved surface. A flat support surface can be formed directly from the side surface of a steel plate, while a curved surface can be formed by bending or cutting the steel plate integrally.

[0047] This embodiment of a heat-dissipating steel billet support frame effectively reduces heat radiation damage to the support frame body 1 through the provision of spacers 3 and heat dissipation channels, thereby extending its service life. Furthermore, the support frame of this embodiment is entirely welded from H-shaped steel and steel plates, significantly reducing the weight of the device compared to traditional billet structures and increasing the actual vehicle load capacity. Furthermore, this embodiment maximizes the weld surface between the guard post 2 and the support frame body 1 to ensure weld strength, thereby enhancing the impact resistance of the guard post 2.

[0048] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
