Description

Technical Field

[0001] The present invention belongs to the technical field of steel transportation, and more specifically, relates to a multifunctional shelf and frame assembly for steel transportation. Background Art

[0002] Steel coils are a type of steel plate. They are actually thin steel plates that are long, narrow and supplied in rolls. They are mainly used in a series of manufacturing industries such as ships, automobiles, locomotives, railways, steel bridges and steel pipes. The total weight of finished steel coils is generally 15-30 tons. In order to meet the demand for steel coils in various major manufacturing industries, special large semi-trailers are generally required for transportation.

[0003] In the actual transportation process, steel coils are generally placed horizontally in the carriage. On the one hand, horizontal placement makes it easier to load and unload the steel coils using cranes or hoists; on the other hand, it can reduce the wear and damage of the steel coils during transportation. However, due to the extremely heavy weight of the steel coils themselves, when the vehicle brakes suddenly, the horizontally placed steel coils are easy to roll out of the carriage under the action of inertia, which seriously threatens the life of the truck driver. For this reason, it is usually necessary to install protective shelves in the carriage to limit the steel coils to prevent them from rolling down and causing safety accidents. However, the existing protective devices have a narrow scope of application and are often only applicable to the transportation needs of steel coils. Therefore, it is of great significance to design a multifunctional shelf that can be applied to the transportation needs of different types of steel.

[0004] After searching, the patent CN219077770U discloses a protective device for the transportation of steel coils. The application fixes the steel coils with a clamp to prevent the steel coils from shaking during transportation. The rotation of the screw drives the telescopic rod to move downward. The telescopic rod squeezes the inner wall of the steel coil and fixes the steel coil against the bottom plate to prevent the steel coils from shaking upward during transportation. According to the different widths of the steel coils, the length of the telescopic rod is adjusted to fix steel coils of different widths, which increases the applicability of the device and improves work efficiency. The patent CN219770627U discloses a steel coil transportation bracket. The application uses a clamping and positioning component to adaptively position and clamp the end face of the steel coil, and the auxiliary bracket fixes the position of the steel coil to ensure the stability of the steel coil during transportation and reduce the collision of the steel coil. The patent CN221586489U discloses a galvanized steel coil transportation protection device. In this application, the main shaft is driven to rotate by the worm shaft at the front of the transport base, so that the main shaft drives the threaded barrel at the front of the expansion table to move, so that the device can adjust the position of the expansion table according to actual conditions, thereby increasing the adaptability of the device.

[0005] The above applications all involve technical improvements to steel coil protection devices, and at the same time, they can be applied to the position limiting operation of steel coils of different widths, increasing applicability. However, the steel coil protection devices of the above applications are not applicable to the transportation needs of steel materials other than steel coils, so their structure needs to be further optimized to meet the transportation needs of different steel materials.

[0008] 2. Technical solution

[0009] In order to solve the above problems, the technical solution adopted by the present invention is as follows:

[0010] The multifunctional shelf for steel transportation of the present invention comprises a shelf body, wherein the shelf body is provided with a first limiting space along a first direction thereof, and a plurality of second limiting spaces are provided along a second direction thereof; a third limiting space is formed on the upper surface of the shelf body; wherein,

[0011] The first direction and the second direction intersect each other, the load-bearing surface of the first limiting space and the second limiting space is a concave surface; the load-bearing surface of the third limiting space is a plane.

[0012] Furthermore, the first limiting space extends continuously along the first direction of the shelf body, and the second limiting space is divided into two sections by the continuously extending first limiting space.

[0013] Furthermore, the second limiting space extends continuously along the second direction of the shelf body, and the first limiting space is divided into multiple sections by a plurality of continuously extending second limiting spaces.

[0014] Further, the first limiting space and / or the second limiting space is a V-shaped concave surface or an arc-shaped concave surface. That is, the first limiting space and the second limiting space are both V-shaped concave surfaces, the first limiting space and the second limiting space are both arc-shaped concave surfaces, or one is a V-shaped concave surface and the other is an arc-shaped concave surface.

[0015] Furthermore, the arc-shaped concave surface is a multi-curvature concave surface composed of at least two arc surfaces with different curvatures.

[0016] Furthermore, the shelf body is formed by integral casting or by processing and welding steel.

[0017] Furthermore, the shelf body is of split design, comprising a first shelf assembly and a second shelf assembly; wherein a first limiting space is formed on the first shelf assembly, a second limiting space is formed on the second shelf assembly, and a third limiting space is formed on the first shelf assembly or the second shelf assembly.

[0018] Furthermore, the first shelf assembly includes a plurality of first support frames arranged at intervals, and adjacent first support frames are welded and connected by reinforcing ribs; a groove is formed on the first support frame, and the grooves on the plurality of first support frames together form the first limiting space; each end of the groove has a plane, which forms the third limiting space.

[0020] The present invention also provides a frame assembly for transporting steel materials, comprising a frame body, wherein a plurality of shelf bodies as described in any one of the above items are arranged in the frame body.

[0021] 3. Beneficial effects

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) The multifunctional shelf for transporting steel materials of the present invention has a first limiting space, a second limiting space and a third limiting space formed on the shelf body at the same time; wherein the first limiting space can be used to place steel coils or short round billets or other cylindrical goods; the second limiting space can be used to place long round billets or other cylindrical goods; the third limiting space can be used to place slabs, steel plates or square billets, etc., so as to be suitable for the transportation needs of steel materials of different specifications, thereby greatly improving the use range of the shelf.

[0024] (2) The multifunctional shelf for transporting steel of the present invention designs the concave surfaces of the first limiting space and the second limiting space as multi-curvature concave surfaces composed of at least two circular arc surfaces with different curvatures, so that round billets or steel coils of different diameters can all be in surface contact with the circular arc surfaces of corresponding curvatures. While ensuring the stable positioning of the steel, it is also helpful to avoid damage to the shelf due to stress concentration at the contact position; at the same time, the round billets or steel coils are in surface contact with the corresponding arc surfaces, which can also protect the outer surface of the steel, which is particularly beneficial when transporting special steels with high surface quality requirements.

[0025] (3) The multifunctional shelf for steel transportation of the present invention adopts a split design for the shelf body, which can effectively reduce the weight of the shelf to increase the actual loading capacity of the vehicle, which is conducive to saving transportation costs.

[0026] (4) The multifunctional shelf for steel transportation of the present invention can form a complete plane on the top of the second support frame by setting the blocking block, so as to meet the transportation requirements of some steel billets with too small width, so as to further improve the application range of the shelf.

[0027] (5) In the frame assembly for transporting steel materials of the present invention, the multifunctional shelf body and the frame body are organically combined through a new design. After being integrated, the overall structural strength is higher and the total weight can be further reduced. When fully loaded with goods, the overall center of gravity is lower, which is more beneficial to prevent goods from falling during transportation and enhance transportation safety.

[0043] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0044] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0045] A multifunctional shelf for steel transportation of the present invention comprises a shelf body 1, on which a first limiting space 2, a second limiting space 3 and a third limiting space 4 are formed. The first limiting space 2 is a groove provided along the first direction of the shelf body 1, and the inner surface of the groove forms a support surface, which can be used to stably limit and support steel coils or short round billets. The second limiting space 3 is a groove provided along the second direction of the shelf body 1, and the groove can be used to stably support some longer round billets. Among them, the first direction and the second direction are two directions intersecting each other. Preferably, the first direction is perpendicular to the second direction, that is, one direction is along the length direction of the shelf body 1, and the other direction is along the width direction of the shelf body 1. The load-bearing surface of the third limiting space 4 is a plane, which can be directly formed by the upper surface of the shelf body 1; or, it can be formed by filling the first limiting space 2 or the second limiting space 3. It is worth mentioning that the specific number of the first limiting space 2 or the second limiting space 3 (including the number of filling) can be set in multiple according to actual transportation needs.

[0046] The present invention is further described below in conjunction with specific embodiments.

[0047] The multifunctional rack for steel transportation in this embodiment can be divided into two types: an integrated rack and a split rack according to the structural form of the rack body 1 .

[0048] Specifically, refer to Figure 1 As shown, as an implementation of an integrated shelf, the shelf body 1 can be integrally formed by casting. Among them, the first limiting space 2 extends continuously along the first direction of the shelf body 1, and the second limiting space 3 is divided into two sections by the continuously extended first limiting space 2. That is, the second limiting space 3 is arranged on the edges of both sides of the shelf body 1, and the first limiting space 2 is penetrated by the second limiting space 3 only in the upper part of both sides, and the bottom of the first limiting space 2 is a continuous supporting surface. At the same time, the top of the edges of both sides of the shelf body 1 where the second limiting space 3 is not provided together form the supporting surface of the third limiting space 4.

[0049] Specifically in this embodiment, two second limit spaces 3 are provided, and each second limit space 3 is formed by two parts. At the same time, the opening depth of the second limit space 3 is about half of the first limit space 2. The advantage of this structural form is that the actual support area of ​​the support surface of the first limit space 2 and the second limit space 3 can be effectively guaranteed by increasing the width of the edges on both sides of the shelf body 1. However, since the second limit space 3 and the first limit space 2 are distributed up and down as a whole, the overall height of the second limit space 3 located above is relatively high, and the center of gravity of the steel placed in the second limit space 3 will naturally be high, which is not conducive to the stability of vehicle driving.

[0050] Figure 2 As another embodiment of the integrated shelf, the shelf body 1 is also formed by casting, but the difference lies in the way the first limiting space 2 and the second limiting space 3 are opened. Figure 2 As shown, the second limiting space 3 extends continuously along the second direction of the shelf body 1, and the first limiting space 2 is divided into multiple sections by a plurality of continuously extending second limiting spaces 3. For ease of understanding, it can be considered that a plurality of second limiting spaces 3 are first opened along the second direction of the shelf body 1, thereby dividing the upper surface of the shelf body 1 into multiple parts. A groove is opened on the upper edge of each part in the second direction, and the plurality of grooves together form the first limiting space 2. The upper surface of the shelf body 1 where the first limiting space 2 and the second limiting space 3 are not opened together forms the support surface of the third limiting space 4.

[0051] Specifically in this embodiment, there are two second confined spaces 3, and the first confined space 2 as a whole is composed of three parts. Of course, the number of the first confined space 2 and the second confined space 3 can be set according to the actual loading requirements. The advantage of this structural form is that the first confined space 2 and the second confined space 3 are actually in a cross-distributed state, which can make the opening depth of the second confined space 3 as close to the first confined space 2 as possible, so as to reduce the center of gravity of the steel in the second confined space 3, which is beneficial to the stability of vehicle driving. However, since the first confined space 2 is divided into multiple parts, the support area of ​​the first confined space 2 is reduced.

[0052] Preferably, protrusions protruding from the upper surface of the shelf body 1 may be provided on both sides thereof to protect the steel materials in the third limiting space 4 .

[0053] refer to Figure 3 As shown in FIG. 1 , as an implementation of the specific shape of the first limiting space 2 and the second limiting space 3, the support surface of the first limiting space 2 and the second limiting space 3 is a V-shaped concave surface. The V-shaped concave surface is convenient for processing on the one hand, and can stably support round billets or steel coils of different diameters on the other hand.

[0054] However, when the round billet or steel coil is placed in the V-shaped concave surface, the two sides of the round billet or steel coil are in line contact with the two planes of the V-shaped concave surface, which is easy to cause stress concentration and damage the outer surface of the round billet or steel coil. Therefore, in the transportation of some special steel materials with high surface quality requirements, in this embodiment, the support surface of the first limiting space 2 and the second limiting space 3 can be designed as an arc-shaped concave surface, so that the round billet or steel coil is in surface contact with the support surface to protect the outer surface of the steel.

[0055] Furthermore, the arc-shaped concave surface is a multi-curvature concave surface composed of at least two arc surfaces with different curvatures, so that round billets or steel coils of different diameters can be in surface contact with the arc surfaces of corresponding curvatures. Of course, according to actual transportation needs, the first limiting space 2 and the second limiting space 3 can be freely combined with V-shaped concave surfaces, arc-shaped concave surfaces and multi-curvature concave surfaces, which are not listed here one by one. At the same time, the number of arc surfaces with different curvatures in the multi-curvature concave surface and the specific curvature can also be adjusted according to actual needs.

[0056] The multifunctional shelf for steel transportation of the present embodiment can be applied to the transportation needs of steels of different specifications, such as steel coils, round billets, square billets, slabs, etc., by setting the first limiting space 2, the second limiting space 3 and the third limiting space 4, thereby greatly improving the applicable scope of the shelf. At the same time, by designing the load-bearing surfaces of the first limiting space 2 and the second limiting space 3 as multi-curvature concave surfaces, circular steels of different diameters can be in surface contact with the load-bearing surface, which can protect the outer surface of the steel, which is more beneficial in the transportation of special steels with high surface quality requirements.

[0057] like Figure 4 As shown, as an embodiment of the split shelf, it includes a first shelf assembly 11 and a second shelf assembly 12. A first limiting space 2 is formed on the first shelf assembly 11, and a second limiting space 3 is formed on the second shelf assembly 12. At the same time, a third limiting space 4 can be formed on the first shelf assembly 11 or the second shelf assembly 12.

[0058] Specifically, Figure 6 As shown, the first shelf assembly 11 includes a plurality of first support frames 111 arranged at intervals, and adjacent first support frames 111 are welded and connected by reinforcing ribs 112. At the same time, a groove is formed on the first support frame 111, and the grooves on the plurality of first support frames 111 together form the above-mentioned first limiting space 2. And each end of the groove has a plane, and the plane forms the above-mentioned third limiting space 4. Among them, the reinforcing rib 112 can be a whole, such as a steel plate. Preferably, the steel plate can be bent or cut into a shape similar to the first support frame 111. Alternatively, the reinforcing rib 112 is composed of a plurality of welded blocks arranged at intervals.

[0059] The second shelf assembly 12 includes two second support frames 121 arranged in parallel, and a plurality of grooves are formed on the second support frames 121. The corresponding grooves on the two second support frames 121 form the above-mentioned second limiting space 3. Of course, the first limiting space 2 and the second limiting space 3 can be the above-mentioned V-shaped concave surface, arc-shaped concave surface or multi-curvature concave surface. At the same time, the two end portions of the second support frame 121 can extend upward to exceed the second limiting space 3, which can further improve the protection effect.

[0060] At the same time, first assembly grooves 1111 for the second support frame 121 to be inserted are provided on the two side planes of the groove on the first support frame 111, so that the second shelf assembly 12 can be quickly assembled and disassembled from the first shelf assembly 11. It should be noted that in this embodiment, when loading steel materials with a flat surface such as billets or slabs, the second shelf assembly 12 needs to be removed from the first shelf assembly 11 to expose the third limiting space 4.

[0061] Further, refer to Fig. 9 As shown, a blocking block 122 may be provided in the groove on the second support frame 121, the top of the blocking block 122 is a plane, and the tops of the plurality of blocking blocks 122 are arranged at the same height to jointly form the third limiting space 4. In this way, the second support frame 121 can be directly welded to the first shelf assembly 11. At the same time, the two ends of the second support frame 121 can extend upward to exceed the top of the blocking block 122, so that the third limiting space 4 can be protected from the side.

[0062] In this embodiment, in order to facilitate the assembly operation between the blocking block 122 and the second support frame 121, the two can be connected in a snap-on manner. For example, a plurality of snap-in blocks are provided on both side surfaces of the blocking block 122, and a stop block is provided on the side wall of the second support frame 121. A limiting groove for the snap-in blocks is formed between the two stop blocks. At the same time, in order to further ensure the stability of the snap-in blocks in the limiting grooves. Locking holes are provided at corresponding positions on the stop block and the snap-in blocks. When the snap-in blocks are inserted into the limiting grooves, the snap-in blocks are locked by pins or bolts. In this embodiment, the shelf body 1 adopts a split design. Compared with the integrated structure, it is not only more convenient to manufacture, but also the shelf body 1 has a lighter weight, which is beneficial to increase the actual loading capacity of the vehicle.

[0063] refer to Figure 5 As shown, as another embodiment of the split shelf, its basic structure is the same as the above, except that the second support frame 121 is set at the end of the first shelf assembly 11, rather than being stuck on the top of the first shelf assembly 11. Preferably, the second support frame 121 can be bolted to the first support frame 111, and there are at least two height positions for adjustment. When the second limited space 3 on the second shelf assembly 12 needs to be used, the second support frame 121 is adjusted to a high position. At this time, the bottom of the second limited space 3 must not be lower than the top of the first support frame 111. When the third limited space 4 on the first shelf assembly 11 needs to be used, the second support frame 121 needs to be adjusted to a low position. At this time, the top of the second limited space 3 needs to be lower than the top of the first support frame 111 to expose the third limited space 4. Of course, the extensions at both ends of the second support frame 121 can exceed the third limited space 4, and the extensions can be used to limit the steel on the third limited space 4 from the side to improve the safety of protection.

[0064] The following is a detailed introduction to the multi-curvature concave surface mentioned in the above embodiment. Among the multiple arc surfaces of the multi-curvature concave surface, there is one arc surface with the largest curvature, and the other arc surfaces are arranged in pairs. The other arc surfaces are distributed in order from large to small along the two ends of the arc surface with the largest curvature, and the arc surfaces arranged in pairs share a common center. At the same time, the centers of the multiple arc surfaces are located on the same vertical line. It is worth mentioning that the curvature of the arc surface is the reciprocal of the radius of the circle where the arc surface is located. That is, the larger the radius of the circle corresponding to the arc surface, the smaller the curvature of the arc surface.

[0065] Specifically in this embodiment, taking the multi-curvature concave surface composed of three different curvatures on the second support frame 121 as an example, refer to Figure 8 As shown, the multi-curvature concave surface is formed by five arc surfaces, namely, arc surfaces a, b1, b2, c1, and c2. Arc surface a is located in the middle of the multi-curvature concave surface, and the curvature of arc surface a is the largest. Arc surface b1 and arc surface b2 are located on both sides of arc surface a respectively, and arc surface b1 and arc surface b2 are two arc segments on the same circle, and the curvatures of the two are the same, and both are smaller than arc surface a. Similarly, arc surface c1 and arc surface c2 are two arc segments on the same circle, and the curvatures of the two are the same, and both are smaller than arc surface b1. Among them, arc surface c1 is located at the end of arc surface b1 away from arc surface a; arc surface c2 is located at the end of arc surface b2 away from arc surface a. When transporting the first round blank that matches with arc surface a, the bottom of the first round blank just fits with arc surface a to form surface contact. When the second round blank matching the arc surface b1 is transported, the two sides of the second round blank respectively fit with the arc surfaces b1 and b2, and a good surface contact can also be formed. Similarly, when the third round blank matching the arc surface c1 is transported, the two sides of the third round blank respectively fit with the arc surfaces c1 and c2, and a good surface contact can also be formed.

[0066] This embodiment also provides a frame assembly for steel transportation, which includes a frame body 5 and a shelf arranged in the frame body 5. The frame body 5 is a new design combined with the above-mentioned shelf, which mainly includes longitudinal beams, cross beams, gantry frames, etc. The shelf can be a shelf body 1 of any structural form in the above-mentioned embodiment; the longitudinal beams, cross beams and the shelf body 1 are organically integrated through a new design, and the shelf becomes a part of the frame assembly structure. Fig.10 The diagram shows the state of the frame assembly equipped with an integrated shelf when loaded with steel coils; Fig.11 The figure shows the state of the frame assembly equipped with an integrated shelf when loaded with long round billets; Fig.12 The diagram shows the state of the frame assembly equipped with a split cargo rack when it is unloaded.

[0067] The following takes the assembly method between the split type shelf and the frame body 5 as an example to explain the assembly relationship between the two in detail. Figure 7 , Fig.13 As shown, a plurality of second assembly grooves 1112 are provided at the bottom of the first support frame 111. At the same time, a plurality of connecting beams 51 for the second assembly grooves 1112 to be clamped are provided in the frame body 5, so that the clamping connection between the shelf body 1 and the frame body 5 can be realized. Of course, the shelf body 1 can also be directly fixedly connected to the frame body 5, for example, by welding, so that the shelf body 1 and the frame body 5 form an integral frame assembly, further improving the overall structural reliability and transportation safety of the device, and at the same time helping to reduce the total weight and cost. In addition, it is worth mentioning that when the frame body 5 is equipped with a split shelf, the first shelf assembly 11 and the second shelf assembly 12 of the split shelf can also be used separately. When the second shelf assembly 12 is disposed on its side, a cushion block can be provided in the frame body 5 to support the second support frame 121, so as to prevent the second support frame 121 from being in a suspended state, thereby avoiding stress concentration at the connection between the second support frame 121 and the first support frame 111.

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 it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
