Technical Field

The invention relates to the technical field of rail transit vehicles, in particular to a supporting structure of a slow hook device and a rail vehicle.

Background

With the development of the track technology, the passive safety of the car body is more and more emphasized by people. The locomotive body collision energy absorption structure mainly comprises a hook buffer device, a supporting structure end structure and other multi-stage energy absorption structures, and only when the multi-stage energy absorption structures can absorb energy orderly and controllably can the multi-stage energy absorption structures be ensured to fully play a role; namely, when two vehicles collide, the coupler and buffer device moves backwards to absorb energy, and when the coupler and buffer device finishes energy absorption, the next-stage energy absorption part is contacted, so that the next-stage energy absorption part triggers energy absorption.

In the existing central coupler draft gear with the coupler yoke, the coupler tail part of the coupler yoke is connected with the front end part of the coupler yoke through a coupler yoke pin, and coupler yoke support bolt installation seats are arranged on the two sides of the lower part of a coupler yoke pin hole; and a support structure for providing vertical support for the coupler and buffer device is arranged at the lower part of the coupler tail frame. However, in use, it often happens that the support structure at the lower part of the coupler yoke contacts the coupler yoke support bolt mounting seat at the lower part of the coupler yoke pin hole before the movable part constant force connector is broken, so that the movable part constant force connector cannot be broken controllably.

Therefore, the technical problem to be solved by those skilled in the art is how to avoid the uncontrollable snapping of the fixed-force connecting piece of the movable part.

Disclosure of Invention

In view of the above, a first object of the present invention is to provide a support structure of a hook release device, which can prevent the uncontrollable snapping of a fixed-force connecting piece of a movable part.

A second object of the invention is to provide a rail vehicle.

In order to achieve the first object, the present invention provides the following solutions:

a supporting structure is used for a coupler buffering device, a coupler box moving part is abutted with the coupler buffering device, the coupler box moving part is arranged on a coupler box fixing part through a moving part constant force connecting piece, the coupler box fixing part is fixed on a vehicle body, a coupler yoke of the coupler buffering device is arranged in the coupler box, a coupler of the coupler buffering device is connected with the coupler yoke through a coupler yoke pin, and the supporting structure comprises a coupler middle front part supporting structure and a coupler yoke middle part supporting structure;

the middle front supporting structure of the coupler is fixed on the car body and used for supporting the coupler;

the coupler tail frame middle supporting structure is fixed on the coupler box fixing part and used for supporting the middle part of the coupler tail frame;

the coupler yoke is characterized in that a coupler yoke pin supporting bolt mounting seat on the coupler yoke can be abutted with a coupler yoke middle supporting structure, and the distance between the front end of the coupler yoke middle supporting structure is larger than the distance between the fixed part of the coupler box and the fixed-force connecting piece of the movable part when the coupler is broken, and the coupler moves backwards.

In a particular embodiment, the support structure further comprises a yoke tail support structure;

the coupler tail frame tail supporting structure is fixed on the coupler box fixing portion and used for supporting the tail of the coupler tail frame.

In another specific embodiment, the yoke middle support structure comprises a mounting flange, a bearing block, a bushing, a first fastener and a second fastener;

the supporting seat is fixed on the top surface of the mounting flange through the first fastening piece, and the supporting seat supports the middle part of the coupler yoke;

and the second fastener sequentially penetrates through the mounting flange and the bushing and is fixed on the fixed part of the car coupler box.

In another specific embodiment, the yoke middle support structure further comprises a connecting plate;

the connecting plate is arranged on the bottom surface of the mounting flange, and the first fastening piece fixes the connecting plate, the mounting flange and the supporting seat together.

In another specific embodiment, the support base comprises a bottom plate, a top plate and a vertical plate;

the vertical plate is welded between the bottom plate and the top plate, the top plate supports the middle of the coupler tail frame, and the bottom plate is fixed on the mounting flange through the first fastening piece.

In another specific embodiment, the risers are symmetrically disposed about the body centerline.

In another particular embodiment, the coupler center front support structure includes a boom, an impact socket, and a equalizer beam;

the impact seat is fixed on the car body, one end of the suspender is connected with the impact seat, the other end of the suspender is connected with the equalizing beam, and the equalizing beam supports the car coupler.

In another specific embodiment, the yoke tail support structure comprises a bracket, a bracket mount, and a wear plate;

the bracket mounting seat is fixed on the fixed part of the coupler box, the bracket is fixed on the bracket mounting seat, the abrasion plate is fixed on the bracket, and the abrasion plate supports the tail part of the coupler tail frame.

The various embodiments according to the invention can be combined as desired, and the embodiments obtained after these combinations are also within the scope of the invention and are part of the specific embodiments of the invention.

Without being limited to any theory, it will be apparent from the above disclosure that the disclosed support structure, in use, secures a front portion support structure on a body of a coupler, supports the coupler, secures a yoke middle support structure on a coupler box securing portion, and supports a middle portion of a yoke. When the locomotive collides, the front supporting structure in the coupler fails, the coupler continues to move backwards, so that the fixed part and the movable part constant force connecting piece of the coupler box break, then the coupler yoke pin supporting bolt mounting seat impacts the front end of the coupler yoke middle supporting structure (specifically the front end of the supporting seat of the coupler yoke middle supporting structure), so that the coupler yoke middle supporting structure fails, and the coupler continues to move backwards, thereby realizing controllable and orderly energy absorption of the subsequent energy absorption structure in the multi-stage energy absorption structure at the end of the locomotive. In the invention, the distance between the coupler yoke key supporting bolt mounting seat on the coupler yoke and the front end of the middle supporting structure of the coupler yoke is larger than the distance of the backward movement of the coupler when the fixed part and the movable part constant force connecting piece of the coupler box are broken, so that the disconnection of the front end of the middle supporting structure of the coupler yoke is realized after the fixed part and the movable part constant force connecting piece of the coupler box are disconnected. The supporting structure at the lower part of the coupler yoke frame is prevented from contacting with the coupler yoke support bolt mounting seat at the lower part of the coupler yoke pin hole of the coupler yoke frame before the movable part constant force connecting piece is broken, and further the situation that the movable part constant force connecting piece cannot be broken controllably is avoided.

In order to achieve the second object, the present invention provides the following solutions:

Because the railway vehicle disclosed by the invention comprises the supporting structure, the supporting structure has the beneficial effects that the railway vehicle disclosed by the invention comprises.
