Description

Top plate structure of railway vehicle through passage

Technical Field

The utility model relates to a rail vehicle link up roof structure of saying belongs to the rail transit vehicle and joins in marriage complete sets.

Background

The through passage of the rail transit vehicle generally comprises a folding shed assembly, a pedal assembly, a top plate assembly and a side wall plate assembly. Wherein the top plate assembly is generally a two-piece metal top plate; two formula roof compression is limited, still can not prevent that the distortion that the vehicle side rolled and brought from influencing the roof life-span, and two formula grafting structure wearing and tearing are comparatively more serious relatively maintain comparatively difficult. Therefore, the prior art also has three-piece type top plates, and the three-piece type top plates are usually connected by adopting two groups of connecting rod assemblies, but the three-piece type top plates have the problem that the torque force is increased when the edge protection plates and the connecting rods move due to the fact that the installation pin shafts of the edge protection plates and the installation seats and the installation pin shafts at the two ends of the connecting rod assemblies are not located on the same axis, so that the service life of the top plates is influenced. And the installation of the roof assembly usually requires several people to hold the roof assembly together, which is very laborious.

Disclosure of Invention

An object of the utility model is to provide a tie point at connecting rod assembly both ends and the mounting point of limit backplate are on same axis, and torsion when can reducing the motion improves life to the laborsaving rail vehicle of installation link up the roof structure of way.

In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a rail vehicle link up roof structure of saying, includes middle backplate, two limit backplate, connecting rod assembly and mount pad, and the middle part and the middle backplate of connecting rod assembly are connected, and two tip of connecting rod assembly are connected with two limit backplate through corresponding first round pin axle respectively to be located the both sides of middle backplate respectively, be equipped with the shaft hole on two limit backplate, have the axis of rotation that stretches into the shaft hole on the mount pad, the shaft hole is located same axis with first round pin axle, and is equipped with the couple on the mount pad.

Preferably, still include the torsional spring, be equipped with the torsional spring pole that supplies the torsional spring suit on the mount pad, and the one end of torsional spring offsets with the mount pad, and the other end offsets with the limit backplate.

Preferably, the linkage assembly has two sets.

Preferably, the hook is hung on a mounting rod of the vehicle body.

After the structure is adopted, the utility model discloses because the first round pin axle at the installation shaft hole of limit backplate and connecting rod assembly both ends is located the same axis. Therefore, the moment of the two connecting points is shortened, the movement torsion generated by the two connecting points is also reduced, and the service life is prolonged. And because the mounting seat is provided with the hook, the hanger can be hung on the vehicle body through the hook in the mounting process, so that the mounting is relatively labor-saving.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments, which are illustrated in the accompanying drawings.

In this embodiment, referring to fig. 1 to 5, a roof structure of a through passage of a rail vehicle includes a middle guard plate 1, two edge guard plates 2, two sets of connecting rod assemblies 3 and a mounting base 4, the middle portion of the connecting rod assembly 3 is connected with the middle guard plate 1, two end portions of the connecting rod assembly 3 are connected with the two edge guard plates 2 through corresponding first pin shafts 31 respectively and are located on two sides of the middle guard plate 1 respectively, shaft holes 21 are formed in the two edge guard plates 2, a rotating shaft 5 extending into the shaft holes is arranged on the mounting base 4, the shaft holes 21 and the first pin shafts 31 are located on the same axis, and hooks 6 are arranged on the mounting base 4.

Referring to fig. 4, the edge protection plate further comprises a torsion spring 7, a torsion spring rod 8 for sleeving the torsion spring 7 is arranged on the mounting seat 4, one end of the torsion spring 7 abuts against the mounting seat 4, and the other end of the torsion spring abuts against the edge protection plate 2. The torsion spring 7 can bear torsion, and the side guard plate 2 is ensured to be smoothly reset in the rotating process.

Referring to fig. 5, the hook 6 is hung on a mounting rod 9 of the vehicle body. In the installation, can hang 6 with the couple and put at installation pole 9, liberate both hands, install more efficiency, also laborsaving relatively.

The mounting seats 4 of the mechanism are provided with four groups and are all fixed on the vehicle body, and the two ends of the two edge protection plates 2 are respectively connected with the corresponding mounting seats 4. Every mount pad 4 is last all to be equipped with couple 6, and in the installation, can hang couple 6 and put at the installation pole 9 of automobile body, it is more efficient laborsaving to install. Referring to fig. 5, the first pin 31 of the present invention is an end connection pin of the connecting rod assembly 3, and the shaft hole 21 of the edge protection plate 2 and the rotation axis 5 of the mounting seat 4 are used for connecting the edge protection plate 2 and the mounting seat 4. The shaft hole 21 and the rotating shaft 5 are located on the same axis as the first pin 31, so that the moment of the two connecting points is shortened, the movement torsion generated by the two connecting points is reduced, and the service life is prolonged.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
