[0002] Traditional container cars operating on railways transport goods via containers, resulting in lengthy loading and unloading times, especially when transporting bulk granular cargo in trains, where rapid loading and unloading is not possible. Furthermore, using traditional railway hopper cars to transport bulk granular cargo can lead to idle vehicles due to capacity constraints and seasonality. To save on vehicle purchase costs while increasing railway vehicle capacity, a multi-purpose freight car is needed for transporting goods on existing railways. Summary of the Invention

[0003] To address the aforementioned technical problems, this application provides a railway flatbed and sluice box wagon, which solves the technical problem that existing railway wagons cannot meet the requirement of multiple uses and have low transportation efficiency.

[0004] The technical solution adopted to achieve the purpose of this application is a railway flatbed shared car, comprising:

[0005] The vehicle body includes a chassis assembly, a locking device, a bottom door, and an opening and closing mechanism for driving the bottom door to open or close, all mounted on the chassis assembly. The chassis assembly is provided with a funnel-shaped compartment, and the bottom door is located on the unloading port of the funnel-shaped compartment to open or close the unloading port under the drive of the opening and closing mechanism.

[0006] The funnel container has a funnel cavity with a unloading funnel opening at the bottom, and the unloading funnel opening is positioned opposite to the funnel cavity.

[0007] In some embodiments, the underframe assembly includes a center beam, side beams located on both sides of the center beam, and a bolster beam connected to the center beam; the locking device is disposed on the side beams.

[0008] In some embodiments, the underframe assembly further includes an upper sidewall mounted on the side beam.

[0009] In some embodiments, the side beam is provided with a guide post, which is located at the end of the upper side wall, and the height of the guide post is greater than that of the upper side wall.

[0010] In some embodiments, the underframe assembly further includes end beams located at the ends of the middle beam and the side beams;

[0011] The car body also includes a bogie, a coupler buffer device, and a braking system; the bogie is mounted on the bolster beam, the coupler buffer device is mounted on the end beam, and the braking system is mounted on the underframe assembly.

[0012] In some embodiments, the bogie integrates a braking device.

[0013] In some embodiments, the railway flat-and-sink shared car includes a box assembly and a ridge assembly mounted on the box assembly, the box assembly and the ridge assembly together forming the funnel cavity; the ridge assembly covers the opening and closing mechanism and the underframe assembly located within the area enclosed by the box assembly.

[0014] In some embodiments, the ridge assembly includes a transverse ridge and a longitudinal ridge, the longitudinal ridge covering the center beam of the underframe assembly, and the transverse ridge covering the opening and closing mechanism.

[0015] In some embodiments, the unloading angle α between the transverse ridge and the longitudinal ridge and the underframe assembly is α > A, where A is the angle of repose of the cargo loaded inside the funnel cavity.

[0016] In some embodiments, the unloading angle α is 50°≤α≤70°.

[0017] In some embodiments, the container assembly includes end wall panels and side wall panels, and the unloading angle β between the end wall panels and the base frame assembly is β > A, where A is the angle of repose of the goods loaded inside the funnel cavity.

[0018] In some embodiments, the unloading angle β is 45°≤β≤70°.

[0019] In some embodiments, the housing assembly further includes a support frame and corner brackets mounted on the support frame.

The hopper container is provided with a hopper cavity at the bottom with a discharge hopper opening, which can be used to load bulk granular goods such as coal. The discharge hopper opening and the hopper compartment are positioned opposite each other, so that the bulk granular goods such as coal loaded in the hopper compartment can fall into the hopper compartment under their own weight. When the opening and closing mechanism drives the bottom door to open, the bulk granular goods can be unloaded. Therefore, the railway flat-and-hopper combined car provided by this application can be used as both a container transport vehicle and a hopper car to transport bulk granular goods such as coal, realizing multiple uses of one car and improving the efficiency of railway vehicle transportation.

Detailed Implementation

[0032] To enable those skilled in the art to better understand this application, the technical solution of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] In railway technology, the direction along which a railway extends is generally referred to as "longitudinal," the horizontal direction perpendicular to the railway's extension is called "lateral," and the vertical direction is called "vertical." Correspondingly, in railway vehicles, "longitudinal" refers to the length direction, and "lateral" refers to the width direction. "End" typically refers to the edge along the length direction, and "side" typically refers to the edge along the width direction. Therefore, in the following text, "longitudinal," "longitudinal," and "length direction of railway vehicles" all refer to the same direction, as do "lateral," "lateral," and "width direction of railway vehicles." For specific definitions of directional terms such as "longitudinal," "lateral," "end," and "side," please refer to the above explanation.

[0034] This application provides a railway leveling and drainage shared car, see [link]. Figure 1 The railway flat-and-slot shared car 100 includes a car body 10 and a funnel container 20 mounted on the car body 10. The funnel container 20 is detachably connected to the car body 10. See also Figure 1 , Figure 2 and Figure 3The car body 10 includes a chassis assembly 11, a locking device 12, a bottom door 13, and an opening and closing mechanism 14. The locking device 12, bottom door 13, and opening and closing mechanism 14 are all mounted on the chassis assembly 11. The locking device 12 is used to engage with the corner fittings 214 of a container, allowing standard containers or hopper containers 20 to be installed on the car body 10. The chassis assembly 11 has a hopper compartment 111 with a discharge port 111a. The bottom door 13 is mounted on the discharge port 111a and is opened or closed by the opening and closing mechanism 14. The number and structure of the bottom door 13 and the opening and closing mechanism 14 are not limited in this application; reference can be made to the current configuration of the bottom door 13 and its opening and closing mechanism 14 in railway hopper cars. The hopper container 20 has a hopper cavity 20a with a discharge hopper opening 20b at the bottom, which can be used to load bulk granular goods such as coal. The unloading funnel opening 20b is positioned opposite the funnel bin 111, allowing bulk granular goods such as coal loaded in the funnel cavity 20a to fall into the funnel bin 111 under their own weight. When the opening and closing mechanism 14 drives the bottom door 13 to open, the bulk granular goods can be unloaded. Therefore, the railway flat-and-slip car 100 provided in this application can be used as both a container car and a funnel car to transport bulk granular goods such as coal, achieving multi-purpose use and improving railway vehicle transportation efficiency.

[0035] The underframe assembly 11 serves as the main load-bearing structure of the railway flatcar 100. Its structure can be installed independently or modified based on the underframe of an existing railway flatcar. The underframe assembly 11 includes a funnel compartment 111, specifically located at the bottom of the underframe assembly 11. Its shape can be referenced to the structure of the unloading port 111a of an existing funnel car. The funnel compartment 111 is connected to the underframe of the underframe assembly 11. In some embodiments, the underframe adopts the boundary conditions of the underframe of a certain model of mass-produced container flatcar, with modifications made to the internal beam structure. See also... Figure 3 The underframe includes a central beam 112 extending longitudinally along the railway. The central beam 112 is the main load-bearing structure of the underframe assembly 11. Locking devices 12, bottom doors 13, and opening / closing mechanisms 14 are all installed on the central beam 112. The position of the locking device 12 is adaptable to 40ft and 20ft container transport. The bottom doors 13 are distributed in the uncovered areas of the central beam 112, symmetrically arranged along the railway crossbeam. The opening / closing mechanism 14 can control the opening and closing of a single bottom door 13 individually, or simultaneously open and close all bottom doors 13. The opening / closing mechanism 14 can be activated by electric drive, hydraulic drive, or by automatically opening and closing the bottom doors 13 through collision with ground facilities. In some embodiments, the car body 10 has a total of 8 bottom doors 13 and 2 sets of opening / closing mechanisms 14. The bottom doors 13 are transverse bottom-opening doors, and the opening / closing mechanisms 14 automatically open and close the bottom doors 13 through collision with ground facilities. Specific structures can refer to relevant prior art disclosures.

[0036] Complete railway vehicles typically also include bogies, couplers and buffers, and braking systems. The railway flatcar 100 of this application is also equipped with the above-mentioned components. The bogie 15 serves as the running gear of the railway flatcar 100. The couplers and buffers 16 are installed at both ends of the vehicle and are the vehicle's traction devices; the braking system 17 includes an air brake 171 and a handbrake 172, and is a safety component for vehicle operation. The specific structures of the above components can be found in relevant prior art disclosures, such as the bogies, couplers and buffers, and braking systems of railway flatcars; specific details are not elaborated here.

[0037] Considering that the underframe assembly 11 needs to install the funnel hopper 111, bottom door 13 and opening and closing mechanism 14, a large installation area needs to be reserved. Therefore, the installation space under the underframe assembly 11 is tight. In order not to interfere with the installation and operation of the bottom door 13, in some embodiments, the bogie 15 integrates a braking device (unit brake cylinder, brake adjuster, etc.). The specific structure can be referred to the relevant disclosures in the prior art, such as the integrated braking bogie disclosed in the utility model patent "Frame-type Bogie with Integrated Braking Device" with publication number CN207725413U.

[0038] The bogie 15, coupler buffer device 16, and braking system 17 are all mounted on the underframe assembly 11. See below. Figure 3 In some embodiments, the underframe assembly 11 includes a center beam 112, side beams 113 located on both sides of the center beam 112, and a bolster beam 114 connected to the center beam 112. A locking device 12 is disposed on the side beams 113, a bogie 15 is mounted on the bolster beam 114, and a coupler buffer device 16 is mounted on the end of the center beam 112. A braking system 17 is mounted on the underframe assembly 11 and can be selectively connected to at least one of the center beam 112, side beams 113, and bolster beam 114, depending on its specific structure and dimensions.

[0039] In the prior art, the central beam 112 of the underframe assembly 11 is relatively large, typically fish-belly shaped, and has high load-bearing capacity. In the railway flatbed wagon 100 provided in this application embodiment, because the underframe assembly 11 needs to accommodate the bottom door 13 and the opening / closing mechanism 14, a large area needs to be reserved for the bottom door 13. Therefore, it is difficult to provide crossbeams for auxiliary load-bearing, resulting in weaker side beams 113 of the underframe assembly 11, which may be prone to bending under heavy loads. Therefore, see [link to relevant documentation]. Figure 2 , Figure 3 and Figure 4In some embodiments, the underframe assembly 11 further includes an upper side wall 116, which is mounted on the side beam 113 and specifically located outside the locking device 12 on the corresponding side beam 113, thereby strengthening the structural strength of the side beam 113. In some embodiments, to further improve the structural strength of the underframe assembly 11, the underframe assembly 11 also includes end beams 115 located at the ends of the middle beam 112 and the side beams 113. The end beams 115 and the side beams 113 together form a rectangular frame, and the coupler buffer device 16 is mounted on the end beams 115.

[0040] Because the longitudinal dimension of the upper sidewall 116 is relatively large, in order to prevent the container from colliding with the upper sidewall 116 during lifting, which could cause deformation of the upper sidewall 116, see [reference needed]. Figure 2 , Figure 3 and Figure 4 In some embodiments, the side beam 113 is provided with guide posts 117, which are located at the ends of the upper side wall 116. The height of the guide posts 117 is greater than that of the upper side wall 116, so that when lifting the container (standard container or funnel container 20), the guide posts 117 first contact the container and guide it, so that the guide posts 117 can smoothly land between the upper side walls 116 on both sides, avoiding collision with the upper side walls 116.

[0041] The hopper container 20 serves as the main cargo-carrying component of the railway flat-and-slip shared car 100. Its structure can be set up independently or modified based on the hopper of an existing container or hopper car. See also... Figure 1 , Figure 5 , Figure 6 and Figure 8 The funnel container 20 includes a container assembly 21 and a ridge assembly 22 mounted on the container assembly 21. The container assembly 21 and the ridge assembly 22 together form a funnel cavity 20a with a unloading funnel opening 20b at the bottom. The ridge assembly 22 covers the opening and closing mechanism 14 and the underframe assembly 11 located within the area enclosed by the container assembly 21, preventing bulk granular goods from falling onto the opening and closing mechanism 14 and the underframe assembly 11. The area not covered by the ridge assembly 22 is the unloading funnel opening 20b of the funnel container 20. The unloading funnel opening 20b is positioned opposite to the funnel compartment 111 of the vehicle body 10. When the opening and closing mechanism 14 drives the bottom door 13 to open, the unloading of bulk granular goods can be realized.

[0042] See Figure 7 , Figure 8 and Figure 9The ridge assembly 22 includes a transverse ridge 221 and a longitudinal ridge 222. The longitudinal ridge 222 covers the central beam 112 of the underframe assembly 11, specifically the beam segment of the central beam 112 exposed within the area enclosed by the box assembly 21. The transverse ridge 221 covers the opening and closing mechanism 14, so that the portion of the vehicle body 10 exposed within the area enclosed by the box assembly 21 is only the funnel hopper 111. Both the transverse ridge 221 and the longitudinal ridge 222 are vertically protruding ridge plates, and the ridge plates are inclined relative to both the vertical and horizontal directions, so that there is a certain included angle (acute angle) between the transverse ridge 221 / longitudinal ridge 222 and the underframe assembly 11. This included angle is the unloading angle α.

[0043] See Figure 7 and Figure 9 The unloading angle α between the transverse ridge 221 and the longitudinal ridge 222 and the base frame assembly 11 is greater than the angle of repose A of the cargo loaded inside the funnel cavity 20a. Taking coal as an example, the angle of repose A of coal is 45°, so the unloading angle α should be greater than 45° to ensure no coal residue during unloading. From the perspective of cargo residue, a larger unloading angle α is better. However, a larger unloading angle α results in larger vertical dimensions of the transverse ridge 221 and the longitudinal ridge 222, which will encroach on the cargo space and reduce the volume of the funnel cavity 20a. Therefore, in some embodiments, the unloading angle α is 50°≤α≤70°, such as 53°, 55°, 58°, 60°, 62°, 66°, 69°, etc.

[0044] See Figure 5 and Figure 8 The housing assembly 21 includes an end wall plate 211 and a side wall plate 212. The end wall plate 211 is inclined relative to both the vertical and horizontal directions, resulting in an acute angle between the end wall plate 211 and the base frame assembly 11. This angle is the unloading angle β. The side wall plate 212 can be arranged vertically or inclined relative to the vertical (satisfying a value greater than the cargo's angle of repose), and this application does not impose any restrictions. The unloading angle β between the end wall plate 211 and the base frame assembly 11 is also greater than the angle of repose A of the cargo loaded inside the funnel cavity 20a. In some embodiments, the unloading angle β is 45°≤β≤70°, such as 47°, 52°, 55°, 58°, 60°, 63°, 66°, 69°, etc.

[0045] In some embodiments, the outer boundary of the funnel container 20 adopts the boundary conditions of a container, see [reference needed]. Figure 5The container assembly 21 of the funnel container 20 also includes a support frame 213 and corner fittings 214 mounted on the support frame 213. The support frame 213 includes frame side columns 2131, frame longitudinal beams 2132, frame transverse beams 2133, and side wall columns 2134. Multiple frame side columns 2131, frame longitudinal beams 2132, frame transverse beams 2133, and side wall columns 2134 are provided, making the support frame 213 form a cuboid with the same boundary conditions as a standard container. The corner fittings 214 include upper corner fittings and lower corner fittings, distributed at the top and bottom four corners of the cuboid support frame 213. Both end wall panels 211 and side wall panels 212 are installed inside the supporting frame 213. Specifically, the upper and lower ends of the end wall panel 211 are connected to two frame beams 2133 respectively, and the left and right sides are connected to two side wall panels 212. The upper and lower ends of the side wall panel 212 are connected to two frame beams 2132 respectively, and the left and right sides are connected to two end wall panels 211. The side wall panel 212 is set vertically, and its outer side is connected to several side wall columns 2134 located on that side.

[0046] Because the end wall panels 211 of the funnel container 20 are inclined, in order to improve the load-bearing capacity of the end wall panels 211, see [reference needed]. Figure 5 In some embodiments, the housing assembly 21 further includes end support plates 23 and end support columns 24. The upper and lower ends of the end support columns 24 are respectively connected to two frame beams 2133, and the end support plates 23 are connected between the end wall plates 211 and the end support columns 24. To further improve stability, two end support plates 23 and two end support columns 24 are provided at the same end, and the two end support plates 23 and two end support columns 24 are symmetrically arranged. The end support columns 24 are inclined relative to both the longitudinal and transverse directions, which increases the area of ​​the end support plates 23. Several through holes are provided on the end support plates 23 for weight reduction.

[0049] Specifically, the railway flat-and-slot shared car 100 includes a base frame assembly 11, funnel containers 20, bottom doors 13 and their opening and closing structures, locking devices 12, a braking system 17, coupler buffer devices 16, and bogies 15. Two sets of funnel hoppers 111 are installed on both sides of the middle section of the base frame assembly 11, and upper side walls 116 are installed on the side beams 113 on both sides. Sixteen sets of telescopic rotary lock locking devices 12 are installed on the side beams 113 of the base frame assembly 11, serving as positioning and locking devices for the corner fittings 214 when transporting different types of containers. The 16 telescopic rotary locks in the locking devices 12 are respectively installed on the side beams 113 of the base frame assembly 11 on both sides of the car body 10. Through different combinations, it can carry 20ft and 40ft standard or funnel containers 20; that is, standard containers or funnel containers 20 can be installed on the upper part of the base frame assembly 11.

[0050] The end wall plate 211 of the funnel container 20 forms a 52° angle with the upper plane of the base frame assembly 11, which facilitates the unloading of goods such as coal. The end wall plate 211 is provided with a diagonal support structure (such as end support plate 23 and end support column 24). The lower part of the funnel container 20 is provided with two unloading funnel openings 20b. The unloading funnel openings 20b are provided with transverse and longitudinal ridge plates. The ridge plates form a 60° angle with the upper plane of the base frame assembly 11. The funnel container 20 is installed on the base frame assembly 11. The unloading funnel openings 20b of the funnel container 20 coincide with the position of the funnel compartment 111 of the base frame assembly 11, which facilitates the unloading of goods in the funnel container 20.

[0051] A bottom door 13 and an opening and closing mechanism 14 are installed at the unloading port 111a of the underframe assembly 11. The opening and closing mechanism 14 adopts a lateral contact structure. The opening and closing arms work in conjunction with the ground facilities to realize one-way automatic opening and closing of the bottom door 13. An air brake device 171 and a hand brake device 172 are used to brake and stop the vehicle, ensuring the safe operation of the vehicle. Coupler buffer devices 16 are installed at both ends of the car body 10 to realize traction and coupling between vehicles. Bogies 15 with integrated brakes are used at both ends of the vehicle, which solves the problem of difficulty in arranging the brake cylinder and brake adjuster in the car body 10 due to the installation of the funnel hopper 111, bottom door 13 and its opening and closing mechanism 14 on the car body 10.
