Embodiment Construction

[0027] Attached below Figure 1 to Figure 5 The door structure of the special rail vehicle described in the present invention is further described in detail.

[0028] Such as figure 1 As shown, the door structure of the special rail vehicle of the present invention is composed of four door leaves 2 side by side, wherein the door leaves on both sides are connected to the car body 10 through three hinges 7 respectively, and the door leaves on both sides and their adjacent door leaves are respectively Connected by two flaps 7 . Therefore, the door leaf in the middle can be opened alone or together with the door leaves on both sides. The door has a large clear width and height, which ensures that large weapons can pass through the door smoothly during loading, and can be opened according to the size of the loaded items. Freely choose the number of door leaves to open, so that loading is convenient, efficient, time-saving and labor-saving. At the outer fixed hinge of the door le...

Abstract

The invention discloses a door structure of a special railway vehicle, and belongs to the field of railway vehicles. The door structure meets the transport requirements for high secrecy, safety and reliability of special vehicles used for transporting national defense safety components. The door structure comprises two sets of door leaves, locking mechanisms and an adjustable sealing mechanism. The door leaves in each set are connected through hinges. The two sets of door leaves are oppositely opened and connected with a vehicle body through hinges. An L-shaped rubber strip is arranged between the door leaves in each set, and L-shaped rubber strips are further arranged between the door leaves and the vehicle body. The two ends of the L-shaped rubber strips are hollow, installed at one ends of the door leaves and arranged in clamping grooves formed in the ends of the door leaves. The other ends, corresponding to the L-shaped rubber strips, of the door leaves or the vehicle body are in a step shape, and two platforms of each step make contact with the two ends of the corresponding L-shaped rubber strip respectively. The door structure has a quite large net passing width and a quite large net passing height, so that it is guaranteed that large weapons can pass through the vehicle door smoothly in the loading process; both sealing and locking of the vehicle door are achieved, so that transport requirements are met and transport safety is guaranteed.
