Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rail vehicles, and in particular relates to a transition coupler. Background Art
[0002] The transition coupler is a transfer coupler used to achieve the transfer between the locomotive coupler and the subway close-coupled coupler during subway shunting, return and rescue. One side of it is connected to the locomotive coupler and the other side is connected to the front end coupler of the subway, allowing the locomotive to drag the subway train. However, in actual use, the transition coupler has some safety hazards.
[0003] Traditional transition couplers are prone to jumping due to the impact of locomotive coupling or emergency braking, and in severe cases, may even detach from the upper side of the locomotive coupler. Furthermore, subway couplers are commonly known to "droop," and the addition of a transition coupler further lowers the coupler height. During operation, the transition coupler can also detach from the lower side of the locomotive coupler due to factors such as track elevation differences or track gradient changes. If the transition coupler detaches from the upper or lower side of the locomotive coupler, it can cause the train to separate, and in severe cases, even cause a derailment or other major accident.
[0004] Existing technologies typically only limit operating speeds to prevent this problem. This restriction not only affects transportation efficiency but also fails to fundamentally eliminate safety hazards. To improve the safety and reliability of railway transportation, it is necessary to design a new type of transition coupler to address the risk of coupler separation caused by the transition coupler jumping out of the locomotive coupler.

[0040] The technical solution of the present invention is described in detail below in conjunction with specific embodiments and the accompanying drawings.
[0041] As attached Figure 1 -Attached Figure 7 As shown, in an illustrative embodiment of a transition coupler of the present invention, the transition coupler includes a hook body and an anti-jump component 3.
[0042] The hook body includes a first connecting component 1 and a second connecting component 2 that are connected to each other.
[0043] The first connecting assembly 1 is disposed on the side connected to the locomotive coupler and comprises at least a mounting plate 11 and an S-shaped arc 12. The arc 12 is fixedly mounted on the side of the mounting plate 11 closest to the locomotive coupler 4, forming a locomotive coupler tongue accommodating cavity between the arc 12 and the mounting plate 11. After the locomotive coupler 4 is connected to the transition coupler, the coupler tongue 231 of the locomotive coupler 4 is inserted into the locomotive coupler tongue accommodating cavity and matingly connected with the arc 12. The side of the mounting plate 11 closest to the close-fitting coupler is fixedly connected to the second connecting assembly 2. In this embodiment, to enhance the overall strength of the transition coupler, the mounting plate 11, the arc 12, and the second connecting assembly 2 are constructed of welded or integrally cast sheet metal.
[0044] The second connecting assembly 2 is arranged on the side connected to the close-fitting coupler, and includes a convex cone 21 and a concave cavity 22 arranged toward the close-fitting coupler. A coupler tongue assembly 23 is arranged in the concave cavity 22 for mating with the close-fitting coupler.
[0045] The anti-jump assembly 3 includes at least one anti-jump member 31. Mounted above or below the locomotive coupler tongue housing, the anti-jump member 31 comprises a stopper section and a connecting section, each formed by bending in sequence. The stopper section extends horizontally, with its end distal to the connecting section connected to the mounting plate 11. When the locomotive coupler 4 and the transition coupler bounce relative to each other, it engages the coupler tongue 231 of the locomotive coupler 4 to maintain position. The connecting section extends vertically, with its end distal to the stopper section connected to the arcuate body 12.
[0046] In the above exemplary embodiment, by installing the anti-jump component 3 on the hook body of the transition coupler, the risk of the locomotive coupler 4 being disengaged from the transition coupler is effectively avoided, and the stability and safety of the connection are improved. The connection state between the locomotive coupler 4 and the transition coupler is as shown in the attached figure. Figure 5 -Attached Figure 7 shown.

The end of the connecting segment is bent horizontally to form a second mounting portion parallel to the top end face or the bottom end face of the arc-shaped body 12, and the second mounting portion is connected to the arc-shaped body 12 by screws.
[0049] In order to improve the installation strength of the anti-jump component 3, in some embodiments of the present invention, as shown in the attached Figure 2As shown, both ends of the anti-jump member 31 are welded to the mounting plate 11 and the arc-shaped body 12 respectively.
[0050] In some embodiments of the present invention, when the two ends of the anti-jump component 31 are detachably connected to the mounting plate 11 and the arc-shaped body 12 by screws, the end of the limiting section is bent to form a first mounting portion parallel to the plate surface of the mounting plate 11, and the first mounting portion is connected to the mounting plate 11 by screws, and the end of the connecting section is bent to form a second mounting portion parallel to the top end face or bottom end face of the arc-shaped body 12, and the second mounting portion is connected to the arc-shaped body 12 by screws.
[0051] As an embodiment of the present invention, as shown in the attached Figure 3 As shown, the anti-jump parts 31 include two, and the two anti-jump parts 31 are respectively installed above and below the locomotive coupler tongue accommodating cavity.
