Description

Run through a shed connection structure

Technical Field

The utility model relates to a through passage of a railway vehicle, in particular to a connection structure of a diaphragm of the through passage of the railway vehicle.

Background

The through passage is a part for connecting two carriages of the railway vehicle, is used for ensuring the safety of passengers during passing, and can prevent wind, rain and sound and heat simultaneously. The through passage has different types, the whole body is made of rubber, and the rain-proof cloth is also pressed on the aluminum framework, the latter is just a through passage folding shed, and the through passage folding shed is divided into an outer folding shed and an inner folding shed.

In the existing connecting structure of the through passage bellows, the through passage bellows and a vehicle body frame connected with a vehicle body are integrated, and the through passage bellows and the vehicle body frame cannot be detached. In the actual use process, the service lives of the vehicle body frame and the folding shed are different, and the service life of the folding shed is obviously shorter than that of the vehicle body frame, so that a customer does not want to replace the vehicle body frame when the service life of the folding shed is due. The integral structure ensures that the folding shed and the vehicle body frame must be replaced simultaneously, thereby causing material waste and high maintenance cost. In another structure, the outer and inner bellows are connected to the vehicle frame, resulting in complicated assembly and disassembly, time consumption and low efficiency.

Disclosure of Invention

In order to solve the problems, the utility model provides the through passage folding shed connecting structure which is simple in structure, convenient to install and disassemble, high in efficiency, material-saving and low in cost.

The utility model relates to a through passage folding shed connecting structure, which comprises a vehicle body frame, an outer folding shed end frame, an inner folding shed end frame and a middle frame; the outer folding shed and the inner folding shed are both composed of a plurality of mutually independent shed cloth units, and adjacent shed cloth units are fixedly connected through a middle frame; the outmost end of the shed cloth unit at the end part of the outer folding shed is provided with an outer folding shed end frame, the outmost end of the shed cloth unit at the end part of the inner folding shed is provided with an inner folding shed end frame, and the outer folding shed end frame, the inner folding shed end frame and the vehicle body frame are fixedly connected in a penetrating manner by the same screw at the same position.

Furthermore, the outer folding shed end frame, the inner folding shed end frame and the vehicle body frame are sequentially arranged from inside to outside.

Furthermore, the outer folding shed end frame is U-shaped, the inner folding shed end frame is inverted Y-shaped, and the two end frames are lapped at the Y-shaped branch of the inner wall of the inner folding shed end frame.

Further, the screw head is located at the outermost vehicle body frame side. Thereby further facilitating installation and removal.

Furthermore, the screws are uniformly distributed in the circumferential directions of the outer folding shed end frame, the inner folding shed end frame and the vehicle body frame.

The through passage folding shed connecting structure is characterized in that the vehicle body frame, the outer folding shed and the inner folding shed are split, and the inner folding shed and the outer folding shed are connected with the vehicle body frame through a row of screws. Therefore, the inner folding shed and the outer folding shed are connected through the same row of screws during installation; when the folding shed is disassembled, the inner folding shed and the outer folding shed can be separated from the vehicle body frame simultaneously only by disassembling one row of screws, the screws of the inner folding shed and the screws of the outer folding shed do not need to be respectively assembled and disassembled, the operation is simple and convenient, and the efficiency is high; in addition, the inner folding shed and the outer folding shed can be separated from the vehicle body frame, the vehicle body frame and the folding sheds do not need to be replaced simultaneously, resources are saved, the environment is protected, the maintenance cost is low, and the product competitiveness is improved.

Drawings

Fig. 1 is a schematic view of a connection structure of a through passage bellows according to the present invention.

Labeled as:

1-a vehicle body frame; 2-external folding shed; 3-inner folding shed; 4-middle frame; 5-inner folding shed end frame; 6-folding the end frame of the shed outwards; 7-screw.

Detailed Description

The connection structure of the through passage bellows according to the present invention will be described in detail with reference to fig. 1.

As shown in figure 1, the through passage folding shed connecting structure comprises a vehicle body frame 1, an outer folding shed 2, an outer folding shed end frame 6, an inner folding shed 3, an inner folding shed end frame 5 and a middle frame 4.

The outer folding shed 2 and the inner folding shed 3 are composed of a plurality of mutually independent shed cloth units, and the adjacent shed cloth units are fixedly connected through a middle frame 4.

The outer end of the shed cloth unit at the end part of the outer folding shed 2 is provided with an outer folding shed end frame 6 which is U-shaped.

The outer end of the shed cloth unit at the end part of the inner folding shed 3 is provided with an inner folding shed end frame 5 which is of an inverted Y shape.

The outer folding shed end frame 6 and the inner folding shed end frame 5 are lapped at the Y-shaped branch position of the inner wall of the inner folding shed end frame 5.

Outer bellows end frame 6, interior

bellows end frame

5, 1 three of automobile body frame are by interior and outer fixed connection in order, run through by same screw 7 in same position, screw 7 head is in 1 one side of the automobile body frame of outermost end to further be convenient for install and dismantle.

The screws 7 are uniformly distributed in the circumferential direction of the outer bellows end frame 6, the inner bellows end frame 5 and the vehicle body frame 1, so that the three are firmly fixed together.
