[0039] As one of the main types of railway transport, the railway open wagon is mainly used for transporting bulk goods such as coal and ore. With the development needs of national economic growth, sustainable ecological environment and upgrading of people's livelihood needs, China's railway freight cars continue to carry out lightweight design to reduce the weight of the vehicle, increase the load of the vehicle, effectively reduce the energy consumption and carbon emission intensity of railway freight transport, and reduce the logistics cost of the whole society. At present, the railway special open wagon in China generally uses carbon steel or stainless steel and other metal materials, compared with the same type of vehicles abroad, there are problems such as heavy weight, easy rust and corrosion, which leads to poor economy of vehicle transportation goods.
[0040] In order to improve the above technical problems to some extent, the present application provides an open wagon and a railway open wagon, which can improve the technical problems of heavy weight and easy rust and corrosion of the railway open wagon in the related art, and improve the economy of vehicle transportation goods.
[0041] The embodiments of the present application will be described below in conjunction with the drawings: Please refer to Figure 1This application provides an open wagon carriage 10, applied to a railway open wagon 1. The open wagon carriage 10 includes a base frame 100, two side walls 200, and two end walls 300. The two side walls 200 are arranged opposite each other along the width direction of the base frame 100, and the two end walls 300 are arranged opposite each other along the length direction of the base frame 100. The base frame 100, the two side walls 200, and the two end walls 300 together form a top-opening accommodating space. The side walls 200 include side wall panels 210 and lower side doors 220. The side wall panels 210 have openings communicating with the accommodating space, and the lower side doors 220 are located at the openings, allowing the openings to be opened or closed. The end walls 300 include end wall panels 310. The side wall panels 210, lower side doors 220, and end wall panels 310 are all integrally formed fiber-based composite sandwich structures.
[0042] The underframe 100 can adopt a flat-bottom structure, eliminating the bottom bathtub compared to traditional railway open wagons, effectively improving the convenience of vehicle inspection and maintenance. The lower side door 220 facilitates manual cleaning of accumulated cargo. The railway open wagon 1 is mainly used for transporting bulk goods such as coal and ore. After mechanized unloading, workers can enter the storage space through the lower side door 220 to clean out any remaining cargo. This eliminates the need for long-distance, high-intensity cargo handling, allowing workers to clean the accumulated cargo from the wagon more conveniently and efficiently, greatly improving working conditions and increasing work efficiency. Specifically, the lower side door 220 can be located in the middle of the side wall panel 210 to shorten the manual handling distance for cleaning accumulated cargo and reduce labor intensity.
[0043] A carbon fiber composite sandwich structure refers to a layered composite structure formed by bonding a core material (such as PVC foam) to a panel made of fiber-based composite material (such as carbon fiber skin or glass fiber skin) with an adhesive. This invention does not strictly limit the carbon fiber composite material used; any carbon fiber composite material conventionally used in the art can be used. Furthermore, the material of the sandwich layer is not strictly limited; for example, it can be a honeycomb sandwich, a foam sandwich, etc.
[0044] The open wagon 10 provided in this application embodiment has a lighter weight and is not prone to rust compared to traditional steel open wagons. The side wall panels 210, lower side doors 220 and end wall panels 310 are all integrally formed fiber composite sandwich structures. Fiber composite sandwich structures are lightweight and do not rust. Therefore, compared to traditional steel open wagons, the open wagon 10 provided in this application embodiment is lighter, does not rust or corrode, and has a longer service life. This can improve the technical problems of heavy weight and easy rust and corrosion of railway open wagons in related technologies, and improve the economic efficiency of transporting goods by vehicle.
[0045] Please see Figures 2-7In some embodiments, the side wall plate 210 comprises a side wall outer skin 211, a side wall core material 212, and a side wall reinforcing structure, the side wall outer skin 211 and the side wall reinforcing structure are both made of fiber-based composite material, the reinforcing structure is arranged inside the side wall outer skin 211, and the side wall core material 212 is filled in the gap between the side wall outer skin 211 and the reinforcing structure.
[0046] The side wall outer skin 211 wraps the internal side wall reinforcing structure and the side wall core material 212 to form a sandwiched “sandwich” structure, and is integrally formed by a vacuum infusion process. The vacuum infusion process is a process known in the art and will not be described here.
[0047] The side wall reinforcing structure is a structural member embedded in the structure of the side wall outer skin 211 during the vacuum infusion process, used to enhance the overall or local strength and stiffness of the side wall plate 210. The side wall core material 212 is a lightweight foam material used to fill the internal cavity of the side wall outer skin 211 and the internal side column 213, as a filler for integrally forming the side wall 200, and to increase the overall strength and stiffness of the side wall plate 210.
[0048] The side wall reinforcing structure comprises a plurality of side columns 213, an upper side beam 214, and a car leaning plate assembly 215. The plurality of side columns 213 are arranged along the length direction of the chassis 100 to improve the overall strength and stiffness of the side wall 200, and the cross section of the side column 213 is in a hollow rectangular structure, which can be made by a fiber-based composite material pultrusion process to reduce the manufacturing cost.
[0049] The plurality of car leaning plate assemblies 215 are arranged one-to-one with the plurality of side columns 213, and the plurality of car leaning plates 2151 protrude from the side of the side wall outer skin 211 away from the accommodation space. The car leaning plate assembly 215 comprises a plurality of car leaning plates 2151 arranged along the height direction of the open wagon compartment 10 to meet the requirements of the car leaning contact during the dumper operation and improve the stress of the vehicle during the dumper operation. The cross section of the car leaning plate 2151 can be in a rectangular solid cross section shape, which can be made by a fiber-based composite material pultrusion process to reduce the manufacturing cost.
[0050] The upper side beam 214 has a special-shaped hollow cross section, which can be made by a fiber-based composite material pultrusion process to reduce the manufacturing cost. The upper side beam 214 is arranged at the top of the side column 213 to provide skeletal support for the side wall 200.
[0051] It should be noted that in order to support the pressure of the goods, many reinforcing ribs are arranged on the wall of the traditional steel open wagon, and the steel structure itself has a certain thickness. After assembly, the wall body is thick. In the fiber composite sandwich structure, the outer composite skin and the internal foam core and composite beam column jointly form a whole force shell. Compared with the traditional side column 213 type side wall 200 structure, the overall thickness of the wallboard can be greatly reduced under the premise of ensuring the overall strength and stiffness, and the volume of the vehicle can be increased.
[0052] Similarly, the lower side door 220 includes a side door outer skin 221 made of fiber composite material and a side door core material 222 filled in the side door outer skin 221. The fiber composite material of the lower side door 220 outer skin wraps the core material to form a sandwich structure, and is integrally formed by a vacuum infusion process. The open wagon compartment 10 further includes a folding leaf 223 for connecting the lower side door 220 and the side wall plate 210, so that the lower side door 220 can open or close the opening. The folding leaf 223 can be made of carbon steel material and is fixedly connected with the integrally formed lower side door 220 by bolts or rivets.
[0053] In some embodiments, the side wall plate 210 is provided with a first recess 216 near one side of the chassis 100, and the lower parts of the plurality of side columns 213 extend to the first recess 216. The first recess 216 is recessed towards the inside of the accommodation space. The bottom of the side wall plate 210 needs to be connected with the chassis 100 by bolts or rivets. The first recess 216 facilitates the fixed connection of the bottom of the side wall plate 210 with the chassis 100 by bolts or rivets, so that the outer surface of the side wall plate 210 can be kept as much as possible on a plane with the outer surface of the side beam 115 of the chassis 100, and the appearance is more flat and beautiful. The lower parts of the plurality of side columns 213 extend to the first recess 216, which can improve the strength and rigidity of the bottom of the side wall plate 210. In some embodiments, the side wall 200 further includes a handrail 230 to meet the climbing needs of personnel in vehicle shunting operations. The side wall plate 210 is provided with a second recess 217 on both sides, and the handrail 230 is arranged in one of the second recesses 217. Since the railway rolling stock has a size limit, the handrail 230 arranged in one of the second recesses 217 can avoid the handrail 230 protruding too much from the outer surface of the side wall plate 210, thereby affecting the volume of the accommodation space.
[0054] In some embodiments, the side wall reinforcing structure further comprises two sets of reinforcing rib assemblies 218, which are arranged inside the side wall outer skin 211 and correspond to the two second recesses 217 respectively, so as to improve the strength and rigidity of the two ends of the side wall panel 210. The reinforcing rib assemblies 218 are arranged in the second recesses 217, and can also avoid the reinforcing rib assemblies 218 from protruding too much from the outer surface of the side wall panel 210, thereby affecting the volume of the accommodation space. Specifically, the reinforcing rib assemblies 218 can comprise a plurality of vertical ribs arranged at intervals in the vertical direction.
[0055] In some embodiments, the side wall panel 210 has a third recess 219, and an opening is arranged in the third recess 219 to avoid the lower side door 220 from protruding too much from the outer surface of the side wall panel 210, thereby affecting the volume of the accommodation space. In addition, the lower side of the third recess 219 is provided with a flow guide slope 2191 to improve the accumulation of spilled goods.

The end wall outer skin 311 and the end wall reinforcing structure are both made of fiber-based composite materials, and the end wall core material 312 is filled in the gap between the end wall outer skin 311 and the reinforcing structure.
[0057] The end wall outer skin 311 wraps the internal end wall reinforcing structure and the end wall core material 312 to form a sandwich structure, and is integrally formed by a vacuum infusion process. The end wall reinforcing structure is embedded in the structure of the end wall outer skin 311 during the vacuum infusion process, and is a structural member for enhancing the overall or local strength and rigidity of the end wall panel 310. The end wall core material 312 is a lightweight foam material, which is used to fill the internal cavity of the end wall outer skin 311 and the internal side column 213, as a filler of the integrally formed end wall 300, and plays a role in increasing the overall strength and rigidity of the end wall panel 310.
[0058] In some embodiments, the end wall reinforcing structure comprises an upper end beam 313 arranged at the top of the end wall outer skin 311 to provide skeletal support for the end wall panel 310. The cross section of the upper end beam 313 is a hollow structure, and specifically, the cross section of the upper end beam 313 can be a special-shaped hollow shape, which is made of fiber-based composite materials by a pultrusion forming process to reduce the manufacturing cost.

The first end beam segment 3131 is matched with the first connecting surface 312, and the second end beam segment 3132 is matched with the second connecting surface 313, so as to improve the connection strength. The first end beam segment 3131 and the first connecting surface 312 can be matched by bolts or rivets, and the second end beam segment 3132 and the second connecting surface 313 can be matched by bolts or rivets.

The floor 120 is located in the accommodation space, a plurality of large cross beams 111 are arranged on the floor 120 along the length direction of the chassis 100, a plurality of small cross beams 112 are arranged on the floor 120 along the length direction of the chassis 100, the large cross beams 111 and the small cross beams 112 are arranged alternately, the two sides of the floor 120 are provided with the side beams 115, the two sides of the floor 120 are provided with the end beams 114, and a plurality of longitudinal beams 116 are arranged on the floor 120 along the width direction of the chassis 100. Wherein, the middle beam 130 is arranged along the length direction of the floor 120, the middle part of the middle beam 130 protrudes away from the floor 120, i.e. the cross section of the middle beam 130 is fish-belly-shaped, which can effectively improve the vertical stiffness of the vehicle.
[0074] In some embodiments, the small cross beam 112 includes two cross beam segments arranged at an angle, one of which is arranged in abutment with the floor 120. The two cross beam segments can be arranged vertically, i.e. the cross section of the small cross beam 112 is L-shaped, and the length of one of the cross beam segments can be greater than the length of the other cross beam segment. The longer cross beam segment is arranged horizontally and is fixedly connected to the bottom of the floor 120 by welding or bolting, and the shorter cross beam segment extends downward, i.e. the cross section of the small cross beam 112 is an open structure and does not form a closed space. In this way, during operation of the vehicle, airflow and vibration can easily blow away or shake off water and dirt accumulated on the shorter cross beam segment. Even if some remains, the contact area with air is large and drying is very fast, thereby effectively reducing accumulated water and reducing the corrosion rate.
[0075] Similarly, the longitudinal beam 116 includes two longitudinal beam segments arranged at an angle, one of which is arranged in abutment with the floor 120. The two longitudinal beam segments can be arranged vertically, i.e. the cross section of the small longitudinal beam 116 is L-shaped, and the length of one of the longitudinal beam segments can be greater than the length of the other longitudinal beam segment. The longer longitudinal beam segment is arranged horizontally and is fixedly connected to the bottom of the floor 120 by welding or bolting, and the shorter longitudinal beam segment extends downward, i.e. the cross section of the small longitudinal beam 116 is an open structure and does not form a closed space. In this way, during operation of the vehicle, airflow and vibration can easily blow away or shake off water and dirt accumulated on the shorter longitudinal beam segment. Even if some remains, the contact area with air is large and drying is very fast, thereby effectively reducing accumulated water and reducing the corrosion rate.
[0076] Based on the same inventive concept, the embodiments of the present application also provide a railway open wagon 1 including the open wagon compartment 10 described above. The railway open wagon 1 provided by the embodiments of the present application has the same beneficial effects as the open wagon compartment 10 described above, and will not be described again here.
[0077] In summary, the open wagon compartment 10 and the railway open wagon 1 provided by the embodiments of the present application can effectively reduce the self weight of the vehicle and increase the load capacity of the vehicle. The "sandwich" side wall 200 structure can effectively reduce the cross section thickness of the side wall 200 and increase the volume of the vehicle compared with the traditional side column 213 type side wall 200 structure. The flat bottom type structure of the underframe 100 cancels the bottom bathtub of the traditional railway special open wagon, which can effectively improve the convenience of vehicle inspection and maintenance. The lower side doors 220 arranged on both sides of the middle of the vehicle shorten the carrying distance of manual cleaning of accumulated cargo and reduce the labor intensity.
[0078] Although the preferred embodiments of the present application have been described, those skilled in the art, once they know the basic inventive concept, can make additional changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.
[0079] It will be apparent to those skilled in the art that various modifications and variations can be made to the present application without departing from the spirit or scope of the application. Thus, it is intended that the present application cover modifications and variations of this application provided they come within the scope of the appended claims and their equivalents.
