Description

Technical Field

[0001] This utility model relates to the field of railway transportation technology, and in particular to a support frame and a transport vehicle. Background Technology

[0002] In existing technologies, specialized support frames are commonly used as the main fixing device for transporting steel coils. These frames are typically made of high-strength steel and designed with a V-shaped support surface that matches the outer contour of the steel coil, effectively preventing it from rolling. To further ensure transport stability, fixed blocks are installed on the side walls of the carriage. These blocks interlock with the limiting structures on the sides of the support frame, thereby positioning and constraining the support frame along the transport direction of the carriage.

[0003] In railway transportation practice, due to differences in design standards and usage requirements, the dimensions and specifications of the side wall blocks of different models of freight cars vary significantly. Since the current load-bearing frames are not very flexible and have poor versatility, it is necessary to equip each model with a load-bearing frame of specific specifications, which increases manufacturing and storage costs.

Obviously, the described embodiments are only some, not all, of the embodiments of 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.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] The first aspect of this utility model is to provide a support frame, such as Figures 1 to 4 As shown, it includes a bracket body 1 and a limiting structure, the limiting structure including a limiting frame 2 and a rotating arm assembly 3; The limiting frame 2 is fixedly connected to the side beam 11 of the bracket body 1. The limiting frame 2 has a first limiting surface 211 and a second limiting surface 212 at both ends of the side beam 11 in the extension direction. The rotating arm assembly 3 is provided with at least one limiting surface. The rotating arm assembly 3 is rotatably connected to the limiting frame 2 so that each limiting surface rotates from above the limiting frame 2 to or out of the side of the first limiting surface 211 opposite to the side of the second limiting surface 212 and / or the side of the second limiting surface 212 opposite to the side of the first limiting surface 211.

[0025] In the carrier frame provided in the above embodiment, the limiting frame 2 is fixedly connected to the side beam 11 and has a first limiting surface 211 and a second limiting surface 212 arranged opposite to each other along the extension direction of the side beam 11. The first limiting surface 211 and the second limiting surface 212 are used to form a limiting engagement with the side wall block 41 of the carriage 4 in the transportation direction. Since the rotating arm assembly 3 is rotatably connected to the limiting frame 2, the limiting surface on it can selectively rotate into or out of the outer area of ​​the first limiting surface 211 and / or the second limiting surface 212 from above, thereby flexibly adjusting the outline size and limiting state of the overall limiting structure according to the size and position of the actual vehicle block 41.

[0026] Compared with the prior art, the support frame provided by the first aspect of this utility model effectively overcomes the problem of poor adaptability to different specifications of carriages due to the fixed structure of traditional special support frames. It eliminates the need to configure a specific support frame for each type of vehicle, significantly reducing manufacturing, maintenance and storage costs.

[0027] In alternative implementations, such as Figure 5 As shown, the distance between the first limiting surface 211 and the second limiting surface 212 on the limiting frame 2 is configured such that the distance between them gradually decreases along the direction of the side beam 11 that is gradually moving away from the bracket body 1. In other words, the first limiting surface 211 and the second limiting surface 212 are not arranged parallel to each other, but rather they are close to each other at a certain angle, forming an inclined structure with a wider opening towards the side beam 11 and gradually narrowing outward.

[0028] like Figure 6 As shown, the sidewalls of the stop block 41, which are positioned opposite each other along the length of the carriage, are typically designed with a certain angle. The closer the stop block 41 is to the center of the carriage 4, the smaller its size along the length of the carriage. By setting the first limiting surface 211 and the second limiting surface 212 to an inclined shape, the overall outline of the limiting frame 2 presents a spatial shape that is wider on the inside and narrower on the outside in the horizontal direction. This better matches the common side slope shape of the stop block 41 on the sidewall of the carriage 4 in actual vehicle models, achieving a larger surface contact or shape matching with the stop block 41, and effectively improving the stability and reliability of the limiting fit.

[0029] In alternative implementations, such as Figure 4 and Figure 5 As shown, the limiting frame 2 includes a limiting plate 21, a first connecting plate 22, and a second connecting plate 23. The first connecting plate 22 and the second connecting plate 23 are arranged opposite to each other along the extension direction of the side beam 11 of the bracket body 1, and are stably assembled with the side beam 11 by welding, bolting, or other reliable mechanical connection methods to ensure that the limiting frame 2 as a whole has sufficient structural strength and stability with the bracket body 1.

[0030] The limiting plate 21 is a rigid plate-shaped component, with its top two ends connected to the first connecting plate 22 and the second connecting plate 23, respectively. The connection can be achieved by welding, riveting, or fasteners. The limiting plate 21 is connected between the first connecting plate 22 and the second connecting plate 23, and its extension direction is consistent with the extension direction of the side beam 11.

[0031] Specifically, the limiting plate 21 has limiting surfaces at its two ends along the extension direction of the side beam 11 for limiting and engaging with the stop block 41 on the side wall of the carriage 4: the end connected to the first connecting plate 22 has a first limiting surface 211, and the end connected to the second connecting plate 23 has a second limiting surface 212.

[0032] Preferably, the limiting plate 21 can be bent into a U-shape, with the first limiting surface 211 located on the vertical flange formed by bending one end of the limiting plate 21, and the second limiting surface 212 located on the vertical flange formed by bending the other end of the limiting plate 21.

[0033] To facilitate the connection between the rotating arm assembly 3 and the limiting plate 21, a mounting plate 213 is fixedly connected to the middle of the limiting plate 21. The mounting plate 213 is set parallel to the vertical direction, providing an installation position for the rotating arm assembly 3.

[0034] In alternative implementations, such as Figure 4 As shown, the rotating arm assembly 3 further includes a first rotating arm 31, which is one of the key moving parts for realizing the limiting function. The first rotating arm 31 is rotatably connected to the mounting plate 213 fixed in the middle of the limiting plate 21 via a rotating shaft structure, so that it can rotate relative to the limiting frame 2 about a predetermined axis.

[0035] Specifically, the rotation axis of the first rotating arm 31 is set to be perpendicular to the extension direction of the side beam 11, so as to realize the operation of rotating in from above and downward and rotating out from the limit area in the use state, which is convenient to adapt to the position of the block 41 on the carriage 4 of different models.

[0036] In addition, the mounting plate 213 is provided with through holes or bearing structures for connecting with the shaft of the first rotating arm 31 to ensure the stability and reliability of the rotating connection.

[0037] Furthermore, the first rotating arm 31 is provided with a third limiting surface 311. The third limiting surface 311 is constructed as a planar structure, and its orientation is perpendicular to the extension direction of the first rotating arm 31. It is used to form a mechanical limit with the stop block 41 on the side wall of the carriage 4 when the first rotating arm 31 rotates to the horizontal position, so as to effectively constrain the bracket body 1 during the vehicle's movement and prevent it from shifting forward or backward or shaking.

[0038] When loading carriages of different sizes, the support frame is lowered from the top of the carriage 4 into the carriage 4 using hoisting equipment. During this process, the stop block 41 may lift the first rotating arm 31. After the lowering is completed, the limit frame 2 limits the support frame body 1. Alternatively, during the lowering process, the stop block 41 may not lift the first rotating arm 31. After the lowering is completed, the first rotating arm 31 limits the support frame body 1.

[0039] The above-described embodiment, by designing the first rotating arm 31 to rotate around an axis perpendicular to the extension direction of the side beam and setting a third limiting surface 311 linked to it, realizes the flexibility of the limiting structure in terms of spatial layout and the adjustability of its function, and significantly enhances the universal adaptability of the support frame to various vehicle models.

[0040] In alternative implementations, such as Figure 4 As shown, the first rotating arm 31 is also provided with a fourth limiting surface 312, which is parallel to the extension direction of the side beam 11. When the first rotating arm 31 rotates in a vertical plane around the rotation axis, the third limiting surface 311 and the fourth limiting surface 312 on it can enter or exit the limiting working state together.

[0041] The fourth limiting surface 312 extends along the length of the side beam 11 and is used to form a mechanical limit with the corresponding side wall block 41 on the carriage 4 when the first rotating arm 31 rotates to the horizontal position, thereby constraining the displacement of the bracket body 1 along the width direction of the carriage 4.

[0042] In alternative implementations, such as Figure 4 As shown, the rotating arm assembly 3 includes a second rotating arm 32, which is rotatably connected to the mounting plate 213 on the limiting frame 2 via a rotating shaft. Its rotation axis is perpendicular to the extension direction of the side beam 11 of the bracket body 1, thereby realizing rotational movement around a vertical plane. The second rotating arm 32 is provided with a fifth limiting surface 321, which is perpendicular to the extension direction of the second rotating arm 32. It is used to mechanically limit the second rotating arm 32 when it is in a horizontal state by forming a stop 41 on the side wall of the carriage 4.

[0043] When the third limiting surface 311 is provided on the first rotating arm 31, the fifth limiting surface 321 and the third limiting surface 311 are respectively provided on both sides of the limiting frame 2 along the extension direction of the side beam 11. Specifically, when the second rotating arm 32 rotates around its rotation axis, the fifth limiting surface 321 can rotate into or out of the side of the first limiting surface 211 away from the second limiting surface 212 from above the limiting frame 2; correspondingly, the third limiting surface 311 is configured to rotate into or out of the side of the second limiting surface 212 away from the first limiting surface 211, and vice versa.

[0044] like Figure 1 and Figure 2As shown, when the support frame is lowered, the stop 41 will not interfere with the first rotating arm 31 and the second rotating arm 32. The bracket body 1 can be limited by the cooperation of the first rotating arm 31 and / or the second rotating arm 32 with the corresponding stop 41; Figure 7 and Figure 8 As shown, when the support frame is lowered, the stop 41 will interfere with the first rotating arm 31 and the second rotating arm 32, pushing the first rotating arm 31 and the second rotating arm 32 to rotate upward. The limit of the bracket body 1 can be achieved by the limit frame 2 itself cooperating with the corresponding stop 41.

[0045] The above-described implementation method enhances the flexibility and adaptability of the limiting structure by introducing a rotating arm structure that can move independently on both sides. It effectively solves the technical problem that traditional fixed bearing frames are difficult to use for multiple vehicle models, and achieves the technical goal of "one frame for multiple uses", which has good engineering application prospects.

[0046] In alternative implementations, such as Figure 4 As shown, the second rotating arm 32 is also provided with a sixth limiting surface 322, which is parallel to the extension direction of the side beam 11. When the second rotating arm 32 is in a horizontal state, the sixth limiting surface 322 forms a mechanical limit with the stop block 41 along the width direction of the carriage 4, limiting the swaying of the bracket body 1 in the width direction of the carriage 4.

[0047] In alternative implementations, such as Figure 3 As shown, at least one pair of limiting structures are connected to the side beam 11 of the bracket body 1. The two limiting structures in each pair are arranged opposite to each other along the extension direction of the side beam 11, and the two limiting structures are symmetrically arranged about the center line between them.

[0048] It is understandable that the aforementioned centerline extends along the width of carriage 4.

[0049] In use, each pair of limiting structures can be used together to limit the position of the bracket body 1.

[0050] A second aspect of this utility model provides a transport vehicle, which includes the aforementioned support frame.

[0051] The transport vehicle provided in the second aspect of this utility model has the support frame provided in the first aspect of this utility model, and thus has all the beneficial effects of the support frame provided in the first aspect of this utility model.

[0052] In an optional embodiment, the transport vehicle includes a compartment 4, the inner wall of the compartment 4 is provided with a plurality of blocks 41, and the compartment 4 may be provided with a plurality of support frames, the side beams 11 of each support frame being connected to at least a pair of limiting structures.

[0053] In each support frame: at least one pair of limiting structures extends between two adjacent stops 41, and / or, at least one stop 41 extends between at least one pair of limiting structures.

[0054] When the support frame is used to load a vehicle model with multiple side wall blocks 41 distributed along the length of the carriage, each pair of limiting structures on the side beam 11 can be flexibly configured in one or a combination of the following two configurations: The first configuration method: (e.g.) Figure 2 and Figure 8 As shown, both limiting structures extend between two adjacent stops 41, and the position of the bracket body 1 relative to the carriage 4 is limited by the limiting surfaces set at the two opposite ends of their respective rotating arm assemblies 3, or the position of the bracket body 1 relative to the carriage 4 is limited by the limiting surfaces set at the two opposite ends of their respective limiting frames 2.

[0055] The second configuration is as follows: a stop 41 extends between the two limiting structures, and the position of the bracket body 1 relative to the carriage 4 is limited by the limiting surface set at the close end of each rotating arm assembly 3, or the position of the bracket body 1 relative to the carriage 4 is limited by the limiting surface set at the close end of each limiting frame 2.

[0056] The two configuration methods mentioned above can be freely combined and applied according to the block 41 layout of different vehicle models.

[0057] 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. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. 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.
