[0001] This invention relates to the field of rail vehicle technology, and more specifically, to a hook-and-slow device mounting structure and a hook-and-slow device. Background Technology

[0002] The bracket structure under the locomotive coupler and buffer is commonly used to install coupler-buffer devices. However, existing coupler-buffer device installation structures have some problems. For example, the transverse coupler bracket under the buffer or coupler tail frame is not suitable for the car body structure of the intermediate end traction seat, especially when the installation space is relatively small, resulting in incompatibility between the buffer and the intermediate end traction seat. In addition, the boom bracket structure under the coupler usually requires adjusting the coupler height by welding steel plates of different thicknesses onto the coupler bracket, which not only increases the construction difficulty but also complicates the process.

[0003] Therefore, how to adapt the hook-and-wind device mounting structure to the vehicle body structure of the intermediate end traction seat has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0042] The core of this invention lies in disclosing a hook-and-wind device mounting structure suitable for a vehicle body structure with a mid-end traction seat.

[0043] Another core aspect of this invention is the disclosure of a hook-and-escape device including the aforementioned hook-and-escape device mounting structure.

[0044] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the invention as described in the claims. Additionally, the complete contents of the structures represented in the embodiments below are not limited to those necessary for the solution of the invention as described in the claims. It should be noted that, for ease of description, only the parts relevant to the invention are shown in the drawings. Unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0045] Combination Figure 1 and Figure 2 The hook and buffer device installation structure disclosed in this invention includes a buffer bracket and a coupler bracket 3. The buffer bracket consists of two independent and spaced-apart brackets (respectively...). Figure 1 The buffer 9 has a left-side buffer bracket 6 and a right-side buffer bracket 5, which are used to connect to the car body 1. The front and rear plates 91 and 92 of the buffer 9 are respectively used to slidably engage with the two buffer brackets. The coupler bracket 3 is used to be mounted on the car body 1, and the coupler 2 is used to be mounted on the coupler bracket 3. The buffer bracket and the coupler bracket 3 do not interfere with each other.

[0046] The present invention supports the two sides of the buffer 9 with two buffer brackets respectively. The space between the two buffer brackets can be used to solve the compatibility problem between the middle end traction seat and the buffer 9. Compared with the one-piece structure of the buffer bracket in the prior art, the split structure of the buffer bracket in the present invention can make full use of the space under the buffer 9, making the structure of the hook and buffer device more compact.

[0047] Combination Figure 7 The buffer 9 is set inside the hook tail frame 10, and the two sides of the buffer 9 exposed on the front plate 91 and the rear plate 92 of the hook tail frame 10 are respectively slidably engaged with the two buffer brackets. The specific structure and function of the hook tail frame 10 are existing technologies and will not be described in detail here.

[0048] Specifically, in combination Figure 3 The buffer bracket includes a mounting plate and a support plate. The mounting plate has a first connection hole 53 for connecting with the vehicle body 1. The support plate is located on one side of the mounting plate and is spaced at a preset distance from the mounting plate by a support plate. The support plate is arranged perpendicular to the support plate and the mounting plate and avoids the first connection hole 53 so that the buffer 9 has a certain installation height relative to the vehicle body. The front follower plate 91 and the rear follower plate 92 of the buffer 9 are slidably mounted on the support plate.

[0049] Furthermore, in a specific embodiment disclosed in this invention, a crushing tube 8 is provided on the hook tail frame 10, and the crushing tube 8 is connected to the coupler 2, combined with... Figure 3 The mounting plate is provided with a positioning protrusion. The end face of the positioning protrusion facing away from the coupler bracket 3 along the extension direction of the mounting plate is the mounting surface 51. The crush tube detection piece 7 is used to be directly pressed and attached to the mounting surface 51 by the crush tube 8. When the crush tube 8 is crushed and absorbs energy, the crush tube detection piece 7 separates from the mounting surface 51, thereby identifying whether the crush tube 8 has been crushed.

[0050] The specific operating mechanisms and operating principles of the aforementioned crush tube detection piece 7 and crush tube 8 are existing technologies and will not be elaborated here.

[0051] Combination Figure 1 and Figure 2 The positioning protrusions of the two buffer brackets are located on their opposite sides to facilitate the installation of the crush tube detection piece 7 and the clamping of the crush tube 8 onto the crush tube detection piece 7. Combined Figure 3 The aforementioned mounting protrusions and mounting plates are typically designed as a single integrated structure.

[0052] For ease of maintenance, a first wear plate 52 is provided on the side of the support plate facing away from the mounting plate. The front follower plate 91 and the rear follower plate 92 of the buffer 9 are mounted on the first wear plate 52 to separate the buffer bracket (support plate) from the front follower plate 91 and the rear follower plate 92 of the buffer 9 and to allow the buffer 9 to slide, thus preventing wear on the support plate. When the first wear plate 52 is severely worn, it can be replaced without replacing the entire buffer bracket.

[0053] Combination Figure 4 In one embodiment, the coupler bracket 3 disclosed in this invention includes a top plate, a bottom plate, and a connecting plate. The coupler 2 is mounted on the top plate, and the bottom plate is mounted on the vehicle body 1 and has a second connecting hole 31 for connecting with the vehicle body 1. The connecting plate is connected between the top plate and the bottom plate and avoids the position of the second connecting hole 31 to avoid affecting the connection between the bottom plate and the vehicle body 1. Compared with a solid structure, the coupler bracket 3 with this frame structure is lighter and easier to disassemble and maintain.

[0054] To facilitate the adjustment of the coupler 2's height for docking with different car body models, the coupler buffer installation structure also includes an adjustment shim 4, combined with... Figure 1 The coupler bracket 3 is adjustablely mounted on the vehicle body 1 via adjusting shims 4, and the adjusting shims 4 are detachably mounted on the vehicle body 1, and there are multiple adjusting shims 4 of different thicknesses. Depending on the actual situation, one adjusting shim 4 or a combination of multiple adjusting shims 4 of different thicknesses can be selected to adjust the height of the coupler 2.

[0055] Furthermore, to facilitate assembly, combined with Figure 5 The adjusting shim 4 has U-shaped holes 41, each U-shaped hole 41 corresponding to one or more second connecting holes 31, and the opening direction of each U-shaped hole 41 is the same and the extension direction is parallel. When replacing or disassembling the adjusting shim 4, it is only necessary to loosen the nuts of the bolts connecting the coupler bracket 3 and the vehicle body 1, and remove or install the adjusting shim 4 along the opening of the U-shaped hole 41, without having to completely remove the bolts before disassembly and assembly, which effectively simplifies the disassembly and assembly steps.

[0056] For ease of maintenance, a second wear plate 32 is provided on the top plate to support the coupler 2 and allow the coupler 2 to slide. The second wear plate 32 can isolate the coupler bracket 3 from direct contact with the coupler 2. When the second wear plate 32 is severely worn, it can be replaced directly.

[0057] The specific structure and replacement method of the above-mentioned wear plates (first wear plate 52 and second wear plate 32) are existing technologies and will not be described in detail here.

[0058] The aforementioned coupler bracket 3 and buffer bracket can be made of materials not limited to carbon steel plates.

[0059] In a specific embodiment disclosed in this invention, combined with Figure 6 and Figure 7 The coupler and buffer device mounting structure is installed inside the coupler box of the car body 1. The height of the coupler bracket 3 can be adjusted by increasing or decreasing the number of adjusting shims 4 or by selecting adjusting shims 4 of different thicknesses, effectively solving the problem of difficulty in adjusting the height of the coupler 2. The two ends of the two buffer brackets are connected to the car body 1 by fasteners, and the buffer 9 is set on the two buffer brackets.

[0060] Combination Figure 8 and Figure 9 The hook-and-buffer device disclosed in this invention includes a buffer 9, a coupler 2, and the aforementioned hook-and-buffer device mounting structure. The front and rear plates 91 and 92 of the buffer 9 are slidably engaged with two buffer brackets on their respective sides. The coupler 2 is mounted on a coupler bracket 3 and connected to the buffer 9. Because it has the aforementioned hook-and-buffer device mounting structure, it also possesses the aforementioned beneficial effects. Other structures can be found in existing technology and will not be described in detail here.

[0061] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Specific technical means in some embodiments may be incorporated, in whole or in part, into another embodiment without being explicitly excluded by another embodiment. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
