A car coupler transition beam structure and a railway vehicle

Abstract

The utility model relates to the technical field of railway vehicles, and particularly discloses a car coupler transition beam structure, which comprises a transition beam main body, a reinforcing connecting plate and a car coupler traction beam. The difference between the minimum distance H between the transition beam main body and the ground and the minimum distance h between the structural floor and the ground is greater than or equal to 40 mm, which is equivalent to increasing the height of the transition beam main body from the ground by at least 40 mm. The other side of the transition beam main body, the reinforcing connecting plate and the car coupler traction beam are connected, so that the installation height space of the car coupler traction beam meets the requirement of 215 mm, thereby ensuring that the car coupler traction beam can be smoothly installed with the car coupler, and effectively solving the problem that the lower surface of the structural floor on the car coupler center to the bottom frame is relatively close, resulting in the problem that the car coupler cannot be installed. In addition, the reinforcing connecting plate is arranged, which can effectively improve the structural strength of the car coupler traction beam and ensure the stability and reliability of the car coupler traction beam.

Description

Technical Field

[0001] This utility model relates to the field of rail vehicle technology, and in particular to a coupler transition beam structure and a rail vehicle. Background Technology

[0002] Currently, the front end of a rail vehicle needs to be equipped with a coupler, which is generally used for rescue coupling and other situations. Therefore, the design of the front end underframe of the head car needs to consider both strength and the installation space for the coupler. The installation height space for the coupler generally refers to the distance between the lower surface of the car body underframe structure at the coupler tail seat and the center of the coupler. According to relevant standards and requirements, the height of the vehicle's interior floor from the rail surface is 1280mm, while the required height of the coupler center from the rail surface is 1000mm, resulting in a required installation height space of 215mm for the coupler.

[0003] In existing technology, because the structural floor on the vehicle chassis is designed as a continuous structure with the traction beam welded integrally to its lower surface, the distance between the coupler center and the lower surface of the structural floor on the chassis is relatively short. Furthermore, since the interior floor is 1280mm above the rail surface and the interior floor layer is 80mm thick, while the structural floor is 70mm thick to ensure the vehicle's load-bearing rigidity and strength, the distance between the lower surface of the structural floor and the rail surface is 1130mm. Meanwhile, the required height of the coupler center from the rail surface is 1000mm. If the front chassis is designed with the traction beam integrally welded to the lower surface of the structural floor, then only 130mm remains between the coupler center and the lower surface of the structural floor on the chassis, failing to meet the 215mm height installation space requirement for the coupler, potentially leading to situations where the coupler cannot be installed. Utility Model Content

[0004] The purpose of this utility model is to provide a coupler transition beam structure and a rail vehicle to solve the problem in the prior art where the distance between the center of the coupler and the lower surface of the structural floor on the base frame is too short, resulting in the inability to install the coupler.

[0005] On one hand, this utility model provides a coupler transition beam structure, which includes: a transition beam body, one side of which can be connected to the structural plate of a rail vehicle; a reinforcing connecting plate, which is connected to the other side of the transition beam body; and a coupler traction beam, the other side of the transition beam body and the reinforcing connecting plate are both connected to the coupler traction beam, and the coupler traction beam can be connected to the coupler; wherein, the minimum distance between the transition beam body and the ground is H, and the minimum distance between the structural plate and the ground is h, where Hh ≥ 40mm.

[0006] As an optional technical solution for the coupler transition beam structure, the minimum distance between the reinforcing connecting plate and the ground is S, where S≥H.

[0007] As an optional technical solution for the coupler transition beam structure, S=H.

[0008] As an optional technical solution for the coupler transition beam structure, the coupler transition beam structure also includes two first side beams. The other side of the main body of the transition beam, the reinforcing connector, and the coupler traction beam are all connected to the first side beams, and the two first side beams are located on both sides of the coupler traction beam.

[0009] As an optional technical solution for the coupler transition beam structure, the coupler transition beam structure also includes a reinforcing plate, and the coupler traction beam and the first side beam are respectively connected to the two sides adjacent to the reinforcing plate.

[0010] As an optional technical solution for the coupler transition beam structure, the coupler transition beam structure also includes a connecting traction beam connected to the coupler traction beam, with one side of the main body of the transition beam and the structural plate respectively connected to the two adjacent sides of the connecting traction beam.

[0011] As an optional technical solution for the coupler transition beam structure, the coupler transition beam structure also includes two second side beams. One side of the main body of the transition beam and the structural plate are connected to the second side beams, and the two second side beams are located on both sides of the connecting traction beam.

[0012] As an optional technical solution for the coupler transition beam structure, the coupler traction beam includes a traction main beam and a fixed beam connected to each other. The fixed beam and the reinforcing connecting plate are connected to the side of the transition beam body away from the ground. The end face of the reinforcing connecting plate away from the ground and the other side of the transition beam body are both connected to the traction main beam.

[0013] As an optional technical solution for the coupler transition beam structure, the fixed beam has clearance holes.

[0014] On the other hand, this utility model provides a rail vehicle including the coupler transition beam structure in any of the above-mentioned schemes.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model provides a coupler transition beam structure, which includes a transition beam body, a reinforcing connecting plate, and a coupler traction beam. Using this coupler transition beam structure, the difference between the minimum distance H between the transition beam body and the ground and the minimum distance h between the structural floor and the ground is greater than or equal to 40mm. This effectively increases the height of the transition beam body from the ground by at least 40mm. Furthermore, by connecting the coupler traction beam to the reinforcing connecting plate on the other side of the transition beam body, the installation height space of the coupler traction beam meets the requirement of 215mm, thus ensuring smooth installation of the coupler traction beam with the coupler. This effectively solves the problem in existing technologies where the distance between the coupler center and the lower surface of the structural floor on the base frame is too short, leading to installation difficulties. Moreover, the reinforcing connecting plate effectively improves the structural strength of the coupler traction beam, ensuring its stability and reliability. Attached Figure Description

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] like Figures 1 to 2 As shown, this embodiment provides a coupler transition beam structure, which includes a transition beam body 1, a reinforcing connecting plate 2, and a coupler traction beam 3. One side of the transition beam body 1 can be connected to the structural floor 8 of the rail vehicle; the reinforcing connecting plate 2 is connected to the other side of the transition beam body 1; both the other side of the transition beam body 1 and the reinforcing connecting plate 2 are connected to the coupler traction beam 3, which can be connected to the coupler; the minimum distance between the transition beam body 1 and the ground is H, and the minimum distance between the structural floor 8 and the ground is h, where Hh ≥ 40 mm.

[0033] The coupler transition beam structure of this invention has a minimum distance H between the transition beam body 1 and the ground, and a minimum distance h between the structural floor 8 and the ground, that is greater than or equal to 40mm. This effectively raises the height of the transition beam body 1 from the ground by at least 40mm. Furthermore, by connecting the coupler traction beam 3 to the other side of the transition beam body 1 via the reinforcing connecting plate 2, the installation height space of the coupler traction beam 3 meets the requirement of 215mm. This ensures that the coupler traction beam 3 can be smoothly installed with the coupler, effectively solving the problem in existing technologies where the distance between the coupler center and the lower surface of the structural floor 8 on the base frame is too short, leading to installation difficulties. Moreover, the reinforcing connecting plate 2 effectively improves the structural strength of the coupler traction beam 3, ensuring its stability and reliability.

[0034] In some embodiments, the minimum distance between the reinforcing connecting plate 2 and the ground is S, where S ≥ H. This setting ensures that the minimum distance between the reinforcing connecting plate 2 and the ground is greater than the minimum distance H between the transition beam body 1 and the ground, thereby ensuring that the installation height space of the coupler traction beam 3 meets the requirement of 215mm, thus guaranteeing that the coupler traction beam 3 can be smoothly installed with the coupler.

[0035] Preferably, S=H. This setting can improve the connection strength between the reinforcing connecting plate 2 and the transition beam body 1.

[0036] In this embodiment, the coupler transition beam structure also includes two first side beams 4. The other side of the transition beam body 1, the reinforcing connecting plate 2, and the coupler traction beam 3 are all connected to the first side beams 4, with the two first side beams 4 located on either side of the coupler traction beam 3. This arrangement further improves the connection strength between the transition beam body 1, the reinforcing connecting plate 2, and the coupler traction beam 3, enabling the transition beam body 1 to withstand the longitudinal force of the coupler and the longitudinal force during energy absorption and anti-climbing actions.

[0037] Furthermore, the coupler transition beam structure also includes a reinforcing plate 5, which connects the coupler traction beam 3 and the first side beam 4 to the two adjacent sides of the reinforcing plate 5, respectively. This further enhances the connection strength between the coupler traction beam 3 and the first side beam 4.

[0038] Optionally, the reinforcing plate 5 is triangular in shape.

[0039] In some embodiments, the coupler transition beam structure further includes a connecting traction beam 6 connected to the coupler traction beam 3, wherein one side of the transition beam body 1 and the structural floor 8 are respectively connected to the two adjacent sides of the connecting traction beam 6. This can further improve the overall structural strength of the coupler traction beam 3.

[0040] Furthermore, the coupler transition beam structure also includes two second side beams 7. One side of the transition beam body 1 and the structural floor 8 are connected to the second side beams 7, and the two second side beams 7 are located on both sides of the connecting traction beam 6. This arrangement can improve the connection strength between one side of the transition beam body 1 and the structural floor 8.

[0041] In this embodiment, the coupler traction beam 3 includes a traction main beam 31 and a fixed beam 32 connected to each other. The fixed beam 32 is connected to the side of the reinforcing connecting plate 2 away from the transition beam body 1, and the end face of the reinforcing connecting plate 2 away from the ground and the other side of the transition beam body 1 are both connected to the traction main beam 31. This achieves the purpose of connecting the coupler.

[0042] Furthermore, the fixed beam 32 has a clearance hole 321, which can be used to avoid the coupler when it is installed.

[0043] This embodiment also provides a rail vehicle including the coupler transition beam structure described above. In the rail vehicle using this invention, the difference between the minimum distance H between the transition beam body 1 and the ground and the minimum distance h between the structural floor 8 and the ground is greater than or equal to 40mm. This effectively increases the height of the transition beam body 1 from the ground by at least 40mm. Furthermore, by connecting the coupler traction beam 3 to the other side of the transition beam body 1 and the reinforcing connecting plate 2, the installation height space of the coupler traction beam 3 meets the requirement of 215mm, thus ensuring that the coupler traction beam 3 can be smoothly installed with the coupler. This effectively solves the problem in the prior art where the distance between the coupler center and the lower surface of the structural floor 8 on the base frame is too short, leading to the inability to install the coupler. Moreover, the reinforcing connecting plate 2 effectively improves the structural strength of the coupler traction beam 3, ensuring its stability and reliability.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
