Description

Traction beam structure and railway freight car adapted for automatic coupler

[0001] The present invention claims priority to the Chinese patent application filed with the Patent Office of China on September 28, 2023, with application number 202311288347.6 and invention name “A traction beam structure and railway freight car adapted to automatic coupler”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present invention relates to the field of railway freight cars, and in particular to a traction beam structure adapted to an automatic coupler and a railway freight car. Background Art

[0003] Typically, railway freight cars are equipped with two types of coupler buffers: chain coupler buffers and automatic coupler buffers. Automatic coupler buffers are typically mechanically connected, requiring manual uncoupling, resulting in low uncoupling efficiency. Currently, to improve vehicle coupling efficiency, the DAC digital automatic coupler has emerged. This coupler not only allows for automatic coupling but also remote uncoupling, resulting in easy operation and high coupling efficiency. Due to its unique advantages, the DAC digital automatic coupler is gradually replacing traditional chain couplers and mechanically connected automatic couplers.

[0004] However, the existing vehicle's traction beam structure cannot simultaneously meet the installation requirements of chain hooks, automatic couplers and DAC digital automatic couplers because it is not designed with components such as buffer rear stops, which affects the application of DAC digital automatic couplers on railway freight cars.

[0005] Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a traction beam structure and a railway freight car that are suitable for automatic couplers. The end beam module reserves installation space for the coupler, and the traction beam module is equipped with a follower plate seat and other structures suitable for chain couplers and automatic coupler buffer devices; it can be applied to different coupler connection types and can realize the transition and conversion between new and old models.

[0007] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0008] In a first aspect, an embodiment of the present invention provides a traction beam structure adapted for an automatic coupler, comprising:

[0009] The traction beam module includes two traction beams arranged opposite to each other, a coupler installation space is formed between the two traction beams, and a front follower plate seat and a rear follower plate seat are connected between the two traction beams;

[0011] Before installation, the traction beam is butted against the middle opening of the coupler mounting plate from one end of the plate seat.

[0013] As a further implementation method, a joist channel steel is fixed to the bottom surface of the end beam lower cover plate, and both ends of the joist channel steel are respectively connected to the second reinforcement plate.

[0014] As a further implementation, both ends of the coupler mounting plate are respectively connected to buffer plates, and the coupler mounting plate forms a concave structure relative to the buffer plates.

[0015] As a further implementation, the traction beam module is a box-type structure.

[0035] Example 1:

[0036] In a typical embodiment of the present invention, as shown in FIG1 , a traction beam structure adapted to an automatic coupler is provided.

[0037] Since the traction beam structure in the prior art cannot simultaneously meet the installation requirements of chain hooks, automatic couplers and DAC digital automatic couplers, the application of DAC digital automatic couplers is limited; based on this, this embodiment provides a traction beam structure that is adapted to automatic couplers, the end beam module 1 is connected to the side beam and side buffer, and the traction beam module 2 is connected to the end beam module 1.

[0038] This embodiment's traction beam structure reserves space for the plate seat after installation (the beam length can be adjusted according to installation requirements). Simultaneously, the beam structure is reinforced (by providing reinforcing ribs at its ends), addressing the existing beam's insufficient strength and meeting the requirements for installing an automatic coupler. This makes it adaptable to various coupler connection types, facilitating transitions between new and old vehicle models.

[0039] The traction beam structure is described in detail below with reference to the accompanying drawings.

[0040] As shown in FIG1 , the end beam module 1 is fixed to one end of the traction beam module 2 . In this embodiment, the two are welded and fixed to form a stable whole.

[0041] As shown in Figures 2 and 3, the end beam module 1 includes components such as a coupler mounting plate, a buffer plate 103, an end beam upper cover plate, and an end beam lower cover plate 104. Among them, there is an opening in the middle position of the coupler mounting plate, which is docked with the interface formed by the traction beam module 2; a buffer plate 103 is connected to each end of the coupler mounting plate, and is fixed to the vehicle body through the buffer plate 103.

[0042] In this embodiment, the front direction is defined as the front of the railway freight car. The side where the buffer plate 103 is installed is the front side, and the other side is the rear side (back side). The end beam upper cover plate and the end beam lower cover plate 104 are parallel to each other and are installed on the back side of the coupler mounting plate. The end beam upper cover plate is fixed to the top of the buffer plate 103 and the coupler mounting plate, and the end beam lower cover plate 104 is fixed to the bottom of the buffer plate 103 and the coupler mounting plate.

[0043] The coupler mounting plate forms a concave structure relative to the buffer plate 103 to facilitate cooperation with the traction beam module 2 .

[0044] In order to increase the structural strength of the end beam module 1 , a reinforcement unit is connected between the end beam upper cover plate and the end beam lower cover plate 104 , and the reinforcement unit is symmetrically arranged relative to the coupler mounting plate.

[0045] As shown in Figure 2, the reinforcement unit includes a first reinforcement plate 107 and a first rib plate 108. The first rib plate 108 is arranged vertically, that is, perpendicular to the direction of the end beam upper cover plate and the end beam lower cover plate 104, and multiple first rib plates 108 are distributed at intervals; the first reinforcement plate 107 is arranged perpendicular to each first rib plate 108, that is, it is arranged in a horizontal direction. The first rib plate 108 and the first reinforcement plate 107 form a grid structure to stably support between the end beam upper cover plate and the end beam lower cover plate 104.

[0046] One or more first reinforcing plates 107 can be provided according to the space size between the end beam upper cover plate and the end beam lower cover plate 104 and the force requirements.

[0047] Since the traction beam module 2, coupler and other structures will generate pressure on the end beam lower cover plate 104, in order to further ensure the structural strength, the joist channel steel 106 is fixed in the middle position of the bottom surface of the end beam lower cover plate 104, and a second reinforcing plate 105 is connected to each end of the joist channel steel 106. The joist channel steel 106 and the second reinforcing plate 105 constitute a bottom reinforcement structure.

[0048] As shown in Figures 4 and 5, the traction beam module 2 is a box-shaped structure, comprising a traction beam 202, a front follower plate seat 201, a rear follower plate seat 209, and a traction beam upper cover plate 207. Two traction beams 202 are positioned opposite each other, forming a coupler installation space between them. The traction beams 202 are welded together using channel steel, I-beams, or rectangular tubes to transmit longitudinal forces.

[0049] A front follower plate seat 201 is installed on the inner side of one end (front end) of the traction beam 202 that cooperates with the end beam module 1, and a rear follower plate seat 209 is provided on the rear side of the front follower plate seat 201. The rear follower plate seat 209 is fixed to the inner wall of the traction beam 202. The front follower plate seat 201 and the rear follower plate seat 209 are used to connect the coupler buffer device.

[0050] A protective plate 210 is installed near the front end of the top of the traction beam module 2, and a cover plate 208 is installed at the rear end. To enhance the structural strength of the traction beam module 2, third reinforcing plates 203 are fixed to the outer sides of the rear ends of the traction beams 202. A fourth reinforcing plate 205 is connected between the two third reinforcing plates 203. A second rib plate 206 is also connected to the rear side of the fourth reinforcing plate 205. The cooperation of the second rib plate 206, the fourth reinforcing plate 205, and the third reinforcing plates 203 strengthens the traction beam module 2.

[0051] At the same time, the bottom of the rear end of the traction beam 202 is connected to the traction pillow connecting plate 204, and the top is connected to the traction beam upper cover plate 207.

[0052] This embodiment reserves space for the installation of couplers, wherein the end beam module 1 is used to install side buffers and provide support for the installation of couplers; the traction beam module 2 is located at the longitudinal center of the car body, and is equipped with a front follower plate seat 201 and a rear follower plate seat 209 on the inside, and a coupler buffer device is installed between the front and rear follower plate seats 209 to transmit longitudinal force; through the cooperation of the end beam module 1 and the traction beam module 2, the traction beam structure can simultaneously adapt to traditional chain hook coupler buffer devices, mechanical automatic couplers and DAC digital automatic couplers, thereby improving the longitudinal dynamics performance of the train and realizing the transition and transformation between old and new models.

[0053] Example 2:

[0054] This embodiment provides a railway freight car, which is equipped with the traction beam structure described in Example 1, wherein the end beam module 1 is equipped with a side buffer, and the traction beam module 2 is located at the longitudinal center of the vehicle body; a coupler buffer device is installed between the front follower plate seat 201 and the rear follower plate seat 209.

[0055] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
