Problems solved by technology

This requires the construction or production of separate passenger platforms, passenger vehicles, passenger vehicle tracks, or separate freight platforms, freight vehicles, and freight vehicle tracks, so the cost of freight or passenger transportation will increase significantly
[0004] For the existing freight trains, their own structure is not conducive to fast loading and unloading, and cannot meet the requirements of fast freight.
And the degree of automation of the freight system is low, and the efficiency of freight loading and unloading is poor

Embodiment 1

[0031] The supporting structure of a rail transit freight car according to the present invention is mainly applied to a rail transit freight car, and the freight car is a double-decker train.

[0032] Such as Figure 1 to Figure 3 As shown, the rail transit truck includes a first layer at the bottom and a second layer above the first layer, that is, the truck adopts a double-layer structure. The first layer at the bottom is used for freight, and the second layer can be used for freight or passenger transportation. In this embodiment, the second layer is the passenger compartment 2 .

[0033] The first floor has a cargo hold space that passes through from one head car to the other head car, and a support structure 4 is arranged in the cargo hold space, and the support structure 4 is used to carry the passenger cabin 2 .

[0034] The cargo compartment space is divided into multiple independent spaces by the supporting structure 4, one part of which is the equipment compartment ...

Embodiment 2

[0039] Such as figure 1 , 2 As shown, in this embodiment, a cargo floor is set in the cargo hold 1, and the cargo floor is divided into a plurality of cuboid blocks, and each cargo floor is provided with a plurality of balls 6, and the balls 6 are used for cargo or containers to be placed in the cargo hold 1. internal displacement.

[0040] A lifting and positioning structure 7 is provided in the cargo compartment 1, and the lifting and positioning structure 7 is used for fixing and positioning goods or containers. Lifting and positioning structure 7 is arranged between two adjacent cuboid block cargo hold floors, and the section shape of lifting and positioning structure 7 is "convex" shape, and lifting and positioning structure 7 cooperates with the bottom of freight container 8. After the container 8 is loaded in place, the lifting positioning structure 7 rises and fixes the container 8 to prevent it from shaking during the operation of the truck and damage the car body s...

Embodiment 3

[0075] In this embodiment, the cargo door is a folding door 5, and the folding door 5 includes an upper page 5-1 and a lower page 5-2. When the folding door 5 is opened, the upper page 5-1 and the lower page 5-2 are folded and overlapped. Realize the opening of the door body.

[0076] The top of the previous page 5-1 is hinged to the car body frame, the bottom of the previous page 5-1 is hinged to the top of the next page 5-2, and a follower device is arranged between the previous page 5-1 and the next page 5-2. When the upper page 5-1 is overturned, the lower page 5-2 is overturned by the follower to realize the folding of the two.

[0077] In this embodiment, the follower device adopts multiple spring hinges or multiple hydraulic hinges.

[0078] Since the outside of the cargo hold door is the loading channel 10, in order to avoid the collision between the door body and the container 8, and also to reduce the distance between the container 8 and the cargo hold 1, the foldin...

Abstract

Provided is a rail traffic van support structure. The rail traffic van support structure comprises cargo hold space, a support structure is arranged in the cargo hold space, and the support structureis a pierced support structure comprising a frame composed of two cross frames and two vertical frames and a strengthening frame arranged in the frame and fixed to the cross frames and / or the verticalframes. In the rail traffic van support structure, the support structure is arranged and optimized, thus the whole support structure has enough support strength, and the safety demand of a cargo holdis met. Meanwhile, the pierced structure is adopted to reduce the self-weight of a van.

Description

technical field [0001] The invention relates to a supporting structure, in particular to a supporting structure for rail transit freight cars. Background technique [0002] With the rapid development of rail transit, it has gradually become the most important part of the land transportation system. [0003] Rail transit includes passenger transport and freight transport. In existing rail transport vehicles, in order to ensure the comfort and safety of passengers, passenger transport and freight transport are generally separated. In this way, separate passenger platforms, passenger vehicles, passenger vehicle tracks, or separate freight platforms, freight vehicles, and freight vehicle tracks need to be constructed or produced, so the cost of freight or passenger transportation will increase significantly. [0004] And for existing freight train, its own structure is unfavorable for fast loading and unloading, can't satisfy the requirement of fast freight. Moreover, the degr...
