BACKGROUND

The statements in this section merely provide basic information related to this application and do not necessarily constitute prior art.

With the rapid development of the railway vehicle industry, AC rigid catenary current collection is a general trend. AC city rail vehicle is different from the design mode of "soft catenary + AC pantograph" for EMU and "rigid catenary + direct current (DC) pantograph" for subway vehicles, most AC city rail vehicles adopt the pantograph-catenary matching method of "rigid-flexible hybrid catenary + AC pantograph", which must take into account the operational characteristics of railway vehicles. However, the actual operation data of the existing urban lines shows that the pantograph-catenary under the existing catenary (especially the new line) has severe sparking phenomenon and the pantograph-catenary vibration is violent.

the upper plate and the middle part of the console are elastically connected by multiple springs;

projections at both ends of the bracket are slidably connected to the corresponding ends of the carbon strip of the main sliding plate so as to collect current as the auxiliary sliding plate; And

a metal air duct of an automatic pantograph lowering system is provided at a lower part of the carbon strip.

As an optional embodiment, the bottom plate is a metal bottom plate.

As an optional embodiment, the bottom plate and the top plate are fixed by bolts.

As an optional embodiment, the top plate, spring and bracket are integrally connected by welding.

As an optional embodiment, the bracket is a metal bracket.

As an optional embodiment, an outwardly projecting slider is provided on one side of each end of the carbon strip of the main sliding plate, and a lower part of the slider is connected to the bottom plate, and an inner wall each end of the console is provided with a sliding groove corresponding to the slider.

Thanks to the connection between the sliding groove and the slider, the longitudinal offset of the carbon strip of the main sliding plate is limited.

As an optional embodiment, an ADD air hose is routed from the middle of the carbon strip of the main sliding plate, a through hole is provided at a corresponding position of the console, and the ADD air hose is extends down from the console through the through hole.

As an optional embodiment, the lower part of the bracket is in the shape of an airfoil, which has a good streamlined shape, low aerodynamic resistance and good current collection performance with the catenary.

As an optional embodiment, the carbon strip of the main sliding plate is made of an impregnated metallic material. The hardness is slightly lower than that of catenary wire.

A pantograph is provided with the aforementioned rigid catenary collector device arranged on a pantograph horn of the pantograph.

As an optional embodiment, two ends of the bracket and the pantograph horn are fixedly connected by bolts.

A railway transport vehicle comprises the aforementioned pantograph or the aforementioned rigid catenary collecting device.

Compared to the prior art, the beneficial effects are provided according to the present application.

According to the rigid catenary collector device provided in the present application, conductive springs are used to ensure the strength of the carbon strip installation structure and to dampen the vibration of the pantograph and the catenary, and have good conductivity to ensure reliable current collection from the catenary.

According to the rigid catenary collector device provided in the present application, a sliding connection between the carbon strip of the main sliding plate and the auxiliary sliding plate, not only limits the offset in both directions of the carbon strip of the sliding plate main caused by the existence of a hard point in the catenary or a foreign body, but also ensures that the space between the main sliding plate and the auxiliary sliding plate is much smaller than the outer diameter of the cross section of the wire catenary, and the space decreases with the wire pressure, which can ensure the reliable frictional contact of the catenary wire between the main and auxiliary sliding plates, and realize safe current collection.

According to the rigid catenary collector device provided in the present application, the hardness of the carbon strip of the main sliding plate is slightly lower than that of the catenary wire, and therefore a stable current collection between the pantograph and the catenary can be realized. while meeting pantograph and catenary wear requirements.

According to the rigid catenary collector device provided in the present application, an integrated metal air duct ADD is provided, and the collector device has the function of triggering an automatic lowering of the ADD pantograph.
