Abstract

A folding-canopy main body used for a train through-passage includes an outward folding-canopy body and an inward folding-canopy body. The folding-canopy main body is vertically provided and extends along a front-back direction. The inward folding-canopy body is formed by connecting at least two pieces of internal canopy cloth which arch inwards to form a U shape along the front-back direction, the outward folding-canopy body is formed by connecting at least two pieces of external canopy cloth which arch outwards to form a U shape along the front-back direction, and the end portions of two adjacent pieces of internal canopy cloth and the end, portions of two adjacent pieces of external canopy cloth are all clamped and riveted by U-shaped parts.

First claim

What is claimed is:

1. A train through-passage, comprising:
two folding-canopy assemblies, wherein the two folding-canopy assemblies are deployed in bilateral symmetry; and
a cab apron assembly, wherein the cab apron assembly is horizontally deployed below the folding-canopy assemblies to form a passage located between the two folding-canopy assemblies,
wherein each folding-canopy assembly comprises:
a vehicle frame mounted on a vehicle end wall;
a folding-canopy main body including:
an outward folding-canopy body, and
an inward folding-canopy body,
wherein the inward folding-canopy body is formed by connecting at least two pieces of internal canopy cloth which arch inwards to form a U shape along the front-back direction,
the outward folding-canopy body is formed by connecting at least two pieces of external canopy cloth which arch outwards to form a U shape along the front-back direction,
end portions of two adjacent pieces of internal canopy cloth and end portions of two adjacent pieces of external canopy cloth are clamped and riveted by U-shaped parts, and
a front side and a rear side of the folding-canopy main body are each connected with a folding-canopy mounting frame, and the folding-canopy mounting frames are detachably connected with the vehicle frame; and

a locking mechanism including a mounting bracket fixedly mounted on a body of a vehicle, a bolt rotatably disposed on the mounting bracket, and a limiting part for limiting the bolt, wherein the locking mechanism is fixedly mounted on the vehicle frame, and adapted to lock the folding-canopy mounting frames and the vehicle frame together or to release the folding-canopy mounting frames from the vehicle frame, and the locking mechanism is switched between the locking state and the releasing state.

2. The train through-passage according to claim 1 , wherein the cab apron assembly comprises:
a cab apron body, wherein the cab apron body is horizontally provided;
two pedals, respectively provided at the front side and the rear side of the cab apron body, wherein the pedals are used for connecting the vehicle ends of carriages and supporting the cab apron body; and
a linkage assembly, used for connecting two adjacent carriages, wherein the linkage assembly is deployed along the front-back direction, the front end and the rear end of the linkage assembly are suitable for connecting the vehicle ends of the carriages, and a positioning mechanism connected with the cab apron body is provided on the linkage assembly,
wherein the positioning mechanism comprises:
a cab apron cover locking plate, wherein the cab apron cover locking plate is connected with the cab apron body;
a linkage positioning plate, wherein the linkage positioning plate is connected with the cab apron cover locking plate; and
a cab apron positioning pin, wherein the cab apron positioning pin is connected with the linkage positioning plate and a linkage respectively.

3. The train through-passage according to claim 2 , wherein the pedal comprises:
a pedal first leaf, wherein the pedal first leaf is horizontally provided and supported below a side edge of the cab apron body, and the pedal first leaf is located at an outer side of the side edge of the cab apron body; and
a pedal second leaf, wherein the pedal second leaf is horizontally provided and supported below the side edge of the cab apron body, and the pedal second leaf is movably connected with the pedal first leaf.

4. The train through-passage according to claim 3 , wherein the pedal first leaf is connected with the pedal second leaf by a hinge.

5. The train through-passage according to claim 2 , wherein the train through-passage also comprises:
pedal supports, wherein the pedal supports are used for connecting the vehicle ends of the carriages, the front end of the linkage assembly and the pedal located at the front side are connected with the pedal support located at the front side, and the rear end of the linkage assembly and the pedal located at the rear side are connected with the pedal support located at the rear side.

6. The train through-passage according to claim 2 , wherein cab apron abrasion bars are provided below the front end and the rear end of the cab apron body, which is supported on the pedals by the cab apron abrasion bars.

7. The train through-passage according to claim 2 , wherein the upper end of the cab apron positioning pin penetrates through the linkage positioning plate and is locked by a cab apron positioning pin locking plate.

8. The train through-passage according to claim 2 , wherein the positioning mechanism also comprises a cab apron cover, a mounting hole is formed in the cab apron body, the cab apron cover is provided in the mounting hole, the cab apron cover is fixedly connected with the cab apron cover locking plate, and the upper surface of the cab apron cover is flush with the upper surface of the cab apron body.

9. The train through-passage according to claim 8 , wherein the cab apron cover locking plate is connected with the cab apron cover by a screw.

10. The train through-passage according to claim 1 , wherein the train through-passage also comprises a support device used for being mounted on a vehicle coupler, and the support device comprises:
a bottom plate, wherein the bottom plate is mounted on the vehicle coupler;
a support frame, wherein the lower end of the support frame is provided with a wear-resisting block and is movably supported on the bottom plate; and
wear-resisting plates, wherein the wear-resisting plates are provided on the bottom plate and limit the support frame along the front-back direction,
wherein the lower end of at least one U-shaped part in the folding-canopy main body is supported on the support frame.

11. The train through-passage according to claim 10 , wherein two wear-resisting plates are deployed in the front and at the behind at an interval, opposite side edges of the two wear-resisting plates are of arc shapes bulging towards opposite directions, and the wear-resisting block extends along the left-right direction and is movably provided between the two wear-resisting plates.
