DETAILED DESCRIPTION

[0038] In view of this, the core of the present invention is to provide a transition coupler that can realize the coupling between type A subway vehicles and type B subway vehicles, so that the comprehensive detection vehicle can be rescued on different subway lines.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Please refer to Figures 1 to 9 .

[0040] The transition coupler disclosed in the embodiment of the present invention is used to connect the first comprehensive inspection vehicle coupler of type A subway and the second comprehensive inspection vehicle coupler of type B subway. The transition coupler specifically includes a first coupler 100 and a second coupler 200 that are connected. The first coupler 100 and the second coupler 200 have different heights from the rail surface of type A subway and different heights from the rail surface of type B subway.

[0041] The first coupler 100 can be connected to the coupler of the first comprehensive inspection vehicle, and the second coupler 200 can be connected to the coupler of the second comprehensive inspection vehicle, so as to realize the coupling of the first comprehensive inspection vehicle and the second comprehensive inspection vehicle.

[0042] When the first comprehensive inspection vehicle or the second comprehensive inspection vehicle breaks down, the first coupler 100 can be connected to the coupler of the first comprehensive inspection vehicle, and the second coupler 200 can be connected to the coupler of the second comprehensive inspection vehicle to tow or push the broken first comprehensive inspection vehicle or the broken second comprehensive inspection vehicle to a nearby vehicle depot or parking lot.

[0043] Compared with the prior art, the transition coupler disclosed in the embodiment of the present invention can realize the coupling between the comprehensive detection vehicle on the A-type subway and the B-type subway, because the first coupler 100 and the second coupler 200 are at different heights from the rail surface of the A-type subway and the rail surface of the B-type subway, so that the comprehensive detection can be rescued on different subway lines.

[0044] It needs to be explained that when the coupler of the first comprehensive inspection vehicle is lower than the coupler of the second comprehensive inspection vehicle, the first coupler of the transition coupler needs to be set lower than the second coupler to realize the connection between the first coupler and the coupler of the first comprehensive inspection vehicle, and the second coupler and the coupler of the second comprehensive inspection vehicle; when the coupler of the first comprehensive inspection vehicle is higher than the coupler of the second comprehensive inspection vehicle, the first coupler of the transition coupler needs to be set higher than the second coupler to realize the connection between the first coupler and the coupler of the first comprehensive inspection vehicle, and the second coupler and the coupler of the second comprehensive inspection vehicle, thereby realizing the coupling of the first comprehensive inspection vehicle on Type A subway and the second comprehensive inspection vehicle on Type B subway.

[0048] The second coupler 200 includes a second hook body 201 and a second connecting portion 202 . The second connecting portion 202 is disposed on the second hook body 201 . The second hook body 201 is used to connect with the second comprehensive detection vehicle coupler, and the second connecting portion 202 is connected with the first coupler 100 .

[0049] As a further embodiment, the first connection portion 102 and the second connection portion 202 disclosed in the embodiment of the present invention are both plate-shaped structures.

[0050] Among them, one side of the first connecting part 102 is a planar structure, and the other side is provided with a first card slot 1021, and a first protrusion 1022 is between two adjacent first card slots 1021; one side of the second connecting part 202 is a planar structure, and the other side is provided with a second card slot 2021 that cooperates with the first protrusion 1022, and a second protrusion 2022 that cooperates with the first card slot 1021 is between two adjacent second card slots 2021.
