Abstract

The utility model relates to a built-in hanger installed at the top of metro vehicle, which comprises edge beams at the top on the both sides of the vehicle, a built-in framework, and two hangers. The hanger comprises a convex edge positioned on the outer side, a fixed edge at the upper end and a fixed plate at the lower end, a clamping groove corresponding to the convex edge on the outer side of the hanger is arranged on the inner wall of the edge beam at the top of the vehicle, the convex edge of the hanger is inserted into the clamping groove of the corresponding edge beams at the top of the vehicle, the fixed edge is fixedly connected with the inner wall of the corresponding edge beams at the top of the vehicle, and the both ends of the built-in framework are respectively fixed with the fixed plates of the both hangers. One end of the hanger is connected through the clamping groove on the edge beam at the top of the vehicle, the other end is connected through a rivet, and thereby the installation and the dismount are convenient; the modularized assembly is realized, which is in favor of the synchronous flow production, and the production coefficient is greatly increased; the operating environment for works is improved, the upward view operation is replaced by overhead view operation, and the operating efficiency is enhanced; the built-in hanger is proved by practice to be a built-in hanger installed at the top of metro vehicle which is secure and reliable.

Description

Dress is hung in the railcar roof

Technical field

The utility model relates to adorning in a kind of railcar roof to be hung, and belongs to the railcar technical field of structures.

Background technology

The roof of present railcar mostly adopts the large-scale hollow aluminium section bar of remaining silent to replace traditional slab and girder, and to hang all be at the various hanging pieces of camber beam assembly welding in car load body framing completion back to dress in the roof of this vehicle.Often adopt a large amount of overhead welding when assembling, be not easy to workman's operation, welding quality is not high, and packaging efficiency is low, is inconvenient to dismantle when safeguarding, brings difficulty to maintenance maintenance, and work capacity is big, and efficient is low.

Summary of the invention

Technical problem to be solved in the utility model is at the deficiencies in the prior art, to provide a kind of interior dress of railcar roof of being convenient to installation and maintenance to hang.

The technical scheme that its technical matters that solves the utility model adopts is as follows: dress is hung in the railcar roof, form the roof side bar that comprises the vehicle both sides, in the frame that frames up, it is characterized in that also having two suspender members, described suspender member has the chimb that is positioned at the outside, the fixed edge of upper end, the adapter plate of lower end, the inwall of described roof side bar has and the corresponding draw-in groove of suspender member outside chimb, the chimb of described suspender member inserts in the draw-in groove of corresponding roof side bar, described fixed edge is captiveed joint with the inwall of corresponding roof side bar, and the two ends of the frame that frames up in described are fixed with the adapter plate of two suspender members respectively.

The beneficial effects of the utility model are as follows: the utility model is simple in structure, has modular construction, is suitable for being installed on railcar and the motor train unit vehicle; Suspender member one end utilizes the draw-in groove of roof side bar, and the other end utilizes rivet coupled, makes things convenient for the installation and removal of suspender member; When assembling, the frame that frames up in the first assembling, and then with the roof upset, the frame that frames up in inciting somebody to action is connected on the suspender member with fastener, has realized modular assembling, helps synchronous Detroit automation, has improved capacity rating greatly; Modular structure also helps safeguarding and changing; Workman's operating environment is improved simultaneously, overlooks operation by looking up to operate to change into, and work efficiency has improved; By this kind structure is carried out strength analysis calculation, result of calculation has proved that this structure satisfies the requirement of strength of hanging fully, is a kind of safe and reliable structure, this structure is applied in the railcar manufacturing of reality, through overtesting and utilization proof, structural safety is reliable.

Description of drawings

Fig. 1 hangs the sectional structure scheme drawing for dress in the utility model railcar roof.

Fig. 2 is the D portion enlarged diagram of Fig. 1.

The specific embodiment

With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in further detail.But the utility model is not limited to given example.

As Fig. 1, shown in Figure 2, dress is hung in the utility model railcar roof, form the roof side bar 21 that comprises the vehicle both sides, 22, in the frame 3 that frames up, it also has two

suspender members

41,42, suspender member 41, identical and the symmetric arrangement of 42 structure, with D portion enlarged diagram among Fig. 1 is that example describes, as shown in Figure 2, suspender member 41 has the chimb 411 that is positioned at the outside, the fixed edge 412 of upper end, the adapter plate 413 of lower end, the inwall of roof side bar 21 has and suspender member 41 outside chimbs 411 corresponding draw-in grooves 211, the chimb 411 of suspender member 41 inserts in the draw-in groove 211 of corresponding roof side bar 21, fixed edge 412 is captiveed joint with the inwall of corresponding roof side bar 21, in the frame up two ends of frame 3 fixing with the adapter plate 413 of suspender member respectively.Among Fig. 1, Fig. 2, label 1 is a roof.

As shown in Figure 2, the fixed edge 412 of suspender member 41 upper ends is captiveed joint by rivet 5 with roof side bar inwall.

Claims

1, dress is hung in the railcar roof, form the roof side bar comprise the vehicle both sides, in the frame that frames up, it is characterized in that also having two suspender members, described suspender member has the chimb that is positioned at the outside, the fixed edge of upper end, the adapter plate of lower end, the inwall of described roof side bar has and the corresponding draw-in groove of suspender member outside chimb, the chimb of described suspender member inserts in the draw-in groove of corresponding roof side bar, described fixed edge is captiveed joint with the inwall of corresponding roof side bar, and the two ends of the frame that frames up in described are fixed with the adapter plate of two suspender members respectively.

2, dress is hung in the railcar roof according to claim 1, it is characterized in that the fixed edge of described suspender member upper end is captiveed joint by rivet with roof side bar inwall.
