[0027] The railway flatcar of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0030] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0031] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to its orientation depicted in the figure of a device. For example, if the device in the figure is inverted, the device described as "above a device or structure" or "over a device or structure" will then be positioned "below a device or structure" or "under a device or structure". Thus, the exemplary term "above" can include both orientations of "above" and "below". The device can also be positioned otherwise (rotated 90 degrees or in other orientations), and corresponding interpretations of the spatial relative descriptions used here are made.

[0032] Please refer to Figure 1-5 , the present utility model provides a technical solution: a flat car for railways, including an outer frame 1, reinforcing square tubes 2, horizontal square tubes 3, traveling wheels 4, connecting ears 5, a base 6, locking bolts 7, locking nuts 8, mounting holes 9, a base plate 10, a sleeve plate 11, positioning bolts 12, positioning holes 13, a blocking plate 14, hanging rings 15, blocking ropes 16, mounting seats 17 and blocking threaded rods 18. Reinforcing square tubes 2 are longitudinally installed on the inner edge of the outer frame 1. A horizontal square tube 3 is fixedly installed at the center of the inner side of the outer frame 1. Traveling wheels 4 are rotatably installed between the inner edge of the outer frame 1 and the reinforcing square tubes 2. Connecting ears 5 are fixed at the front end of the outer wall of the outer frame 1. A base 6 is installed on the outer edge of the outer frame 1;

[0033] A locking bolt 7 is installed through the base 6. A locking nut 8 is installed on the top of the locking bolt 7. The locking bolt 7 passes through the mounting hole 9, and the mounting hole 9 is opened on the edge of the outer frame 1. A base plate 10 is fixed on the outer side surface of the base 6;

[0034] A sleeve plate 11 is installed on the base plate 10. A positioning bolt 12 is threadedly installed on the outer side surface of the sleeve plate 11. The end of the positioning bolt 12 is connected to the positioning hole 13, and the positioning hole 13 is opened on the outer side surface of the base plate 10. A blocking plate 14 is fixed on the outer side surface of the sleeve plate 11. A hanging ring 15 is installed on the blocking plate 14. A blocking rope 16 is installed on the hanging ring 15.

[0035] In this example, the front view sectional shape of the base 6 is a "C" shape, and the length of the horizontal part of the base 6 is greater than 3 / 4 of the width of the outer frame 1. The above structural design enables the base 6 to be stably installed on the edge of the outer frame 1, ensuring the stability of the base 6 and the structures connected thereto.

[0036] In this example, the base 6 and the substrate 10 are symmetrically distributed about the center of the outer frame 1. The top view length of the substrate 10 is greater than 3 / 4 of the top view length of the base 6. The above structural design results in high structural strength of the base 6 and the substrate 10, which can provide a stable mounting foundation for the mounting mechanism on it.

[0037] In this example, the sleeve plate 11 is slidably connected to the base plate 10. The base plate 10 has positioning holes 13 arranged longitudinally at equal intervals on its outer surface. The above structural design allows the sleeve plate 11 to slide along the base plate 10 to adjust its working height and to be quickly locked by connecting the positioning bolt 12 to the positioning hole 13.

[0038] In this example, the positioning bolt 12 and the positioning hole 13 are threaded together. The center of the positioning bolt 12 and the center of the sleeve 11 are on the same vertical plane. The above structural design can stably fix the working position of the sleeve 11.

[0039] In this example, the blocking plates 14 are symmetrically distributed about the center of the sleeve plate 11. Hanging rings 15 are evenly spaced on the top and bottom surfaces of the blocking plates 14. The above structural design can provide stable shielding and protection from both sides.

[0040] In this example, mounting bases 17 are symmetrically fixed on the top surfaces of the front and rear ends of the outer frame 1. A blocking threaded rod 18 is installed on the mounting base 17. The above structural design can provide stable shielding and protection from the front and rear sides.

[0041] In this example, the inner wall of the mounting base 17 is threaded to the bottom end of the thread-blocking rod 18. The mounting bases 17 are evenly spaced. The above structural design allows the thread-blocking rods 18 to be easily installed and removed, and the number of installations can be easily adjusted according to the size of the goods.

[0042] Working principle: First, tools, materials, small machinery and personnel are loaded onto the flatbed consisting of the outer frame 1, reinforcing square tube 2 and horizontal square tube 3 without the base 6, base plate 10 and blocking threaded rod 18 installed.

[0043] After loading, depending on the size of the tools, materials, and small machinery, or the number of personnel, rotate the appropriate number of blocking threaded rods 18 onto the mounting base 17, and place the base 6 as... Figure 3 The horizontal clip shown is placed on the outside of the outer frame 1. Align the holes on the upper and lower parts of the base 6 with the mounting holes 9. Use the locking bolt 7 to pass through the holes on the upper and lower parts of the base 6 and the mounting holes 9. Install the locking nut 8 and washer on the top of the locking bolt 7 and tighten it to fix it.

[0044] Then, a suitable number of sleeve plates 11 are slidably installed on the base plate 10 from the top of the base plate 10. The height of the sleeve plates 11 is adjusted by sliding until the height of the sleeve plates 11 is appropriate. The positioning bolts 12 are rotated and threadedly connected to the corresponding positioning holes 13 for fixation. The blocking ropes 16 are fixed between the blocking plates 14 through the hanging rings 15. Tools, materials, small machinery and personnel can then be transferred. After reaching the destination, the blocking threaded rods 18 are unscrewed, the locking nuts 8 are removed from the top of the locking bolts 7, and the locking bolts 7 are pulled out from the mounting holes 9. The base 6 is then moved horizontally to detach from the outer frame 1, and tools, materials, small machinery and personnel can then be unloaded.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
