Problems solved by technology

[0003] In the process of field application, especially the technical configuration adopted by domestic EMU trains is different, and the size of the connecting surface of the front coupler of each model is different, so the use of the current transitional coupler has great limitations: the existing transitional coupler is only equipped with a single auxiliary The connecting device and the auxiliary connecting device are fixed and non-rotatable. They are only suitable for the front-end coupler equipped with a single vehicle type. When in use, they can only be manually connected to the close-fitting coupler, and then connected to the traction coupler of the locomotive by impact. Flexible less versatile

Embodiment 1

[0025] see figure 1 and figure 2 , an auxiliary coupling device for a transitional coupler, used for coupling the front-end coupler of a vehicle, the device includes an auxiliary hook, a support 1, a locking device, a fastener 2 and a pivot pin 3, and the auxiliary hook includes a hook facing downwards 4 and the hook connecting column 5, and the hook 4 is horizontally arranged on the side of the hook connecting column 5, the upper end of the hook connecting column 5 is integrally formed with the hook 4, the bottom end of the hook connecting column 5 is connected with the rotating shaft pin 3, and the hook connecting column 5 can be Rotate synchronously with the pivot pin 3, when the position of the hook 4 and the front coupler are not uniform, the pivot pin 3 can be rotated to drive the auxiliary hook to rotate to the coupler coupling angle; when the auxiliary coupling function is not needed, the pivot pin 3 can be rotated to drive the auxiliary hook Rotate to an appropriate...

Embodiment 2

[0032] The structure and composition of the auxiliary connecting device of embodiment 2 are basically the same as that of embodiment 1, and the difference technical feature is that there is one hook 4 in total, and the hook 4 is arranged at the upper end of the side of the hook connecting column 5 .

Embodiment 3

[0034] The structure and composition of the auxiliary connecting device of embodiment 3 and the auxiliary connecting device of embodiment 1 are basically the same, and the difference technical features are: as Figure 5 As shown, there are 2 hooks 4 in total, and the 2 hooks are arranged at the upper end of the side of the hook connecting column 5 at intervals of 180°.

Abstract

The invention relates to an auxiliary coupling device for a transition car coupler. The auxiliary coupling device is used for hooking a front-end coupler of a car, and comprises an auxiliary hook, a support, a locking device, fasteners and a rotary shaft pin, the auxiliary hook comprises a downward hook body and a hook connecting column, the upper end of the hook connecting column and the hook body are integrally formed, and the bottom end of the hook connecting column is connected with the rotary shaft pin. A counter bored hole is formed in the middle of the support, the hook connecting column longitudinally penetrates through the counter bored hole, the hook connecting column and the rotary shaft pin synchronously rotate under the supporting function of the counter bored hole, the rotary shaft pin can be rotated to drive the auxiliary hook to rotate by a car coupler coupling angle, the rotary shaft pin can be rotated to drive the auxiliary hook to rotate by a proper angle, it is guaranteed that any hook cannot stretch out of the coupling face, the normal work of automatic coupling is not influenced, manual coupling of the device and the front-end coupler can be achieved, the auxiliary hook can be rotated to different positions, the device can be coupled with a sealing car coupler or a locomotive coupler firstly in the using process, and the flexibility and universality of on-site shunting and reconnexion work are improved.

Description

technical field [0001] The invention relates to a vehicle coupler connecting device, in particular to an auxiliary connecting device for a transitional coupler. Background technique [0002] The transition coupler is usually used to connect the transported vehicle and the power locomotive, and is an important device for vehicle shunting operations, train return and rescue. In the field of high-speed trains, intercity EMUs and urban rail vehicles, the transition coupler of the close-connected automatic coupler-buffer device is very common. [0003] In the process of field application, especially the technical configuration adopted by domestic EMU trains is different, and the size of the connecting surface of the front coupler of each model is different, so the use of the current transitional coupler has great limitations: the existing transitional coupler is only equipped with a single auxiliary The connecting device and the auxiliary connecting device are fixed and non-rota...
