Abstract
The utility model discloses a modularized middle top structure of a metro vehicle. The modularized middle top structure of the metro vehicle comprises beams, a middle top plate, lamp supports and a blowing-in grille. The beams are arranged in parallel. Two rows of lamp supports are parallelly arranged below each beam and perpendicular to the beams. The middle top plate is arranged below the beam and arranged between the two rows of the lamp supports. The blow-in grille is arranged outside the lamp supports. Middle handrail installation seats are arranged in the middle of the beams and lateral side handrail installation seats are arranged on upper ends of the beams. The modularized middle top structure of the metro vehicle has the advantages that the modularized structure is formed so as to be simple and clear, repeated labor in installing spare parts one by one is avoided, working efficiency is improved and labor cost is saved; in time of installation on a vehicle, installation is simple and rapid, operation difficulty for workers on the vehicle is reduced and operation is convenient; a middle top module works under the vehicle, uniformity of a middle top combination seam is improved and quality of products is improved and a secondary framework is removed so as to be beneficial to weight lightening of the whole vehicle.
Description
Technical field
The utility model relates to a kind of railcar parts, particularly roof construction in a kind of railcar modularization.
Background technology
It is first middle top board to be fixed on the secondary skeleton by screw that the interior trim mounting structure is divided at the middle top on traditional railcar top, then by public screw middle top board and grid one side are fixed on the secondary skeleton, the opposite side of grid is screwed first, then by public bolt grid and light fixture one side are connected on the secondary skeleton, the light fixture opposite side is connected on the secondary skeleton with bolt.Secondary skeleton top is fixed on the ceiling steel structure by flap seat, this middle roof construction is installed comparatively complicated, loaded down with trivial details, not only should be noted that the order that screw and bolt are put, also must be noted that to adjust the homogeneity of seam between the homogeneity of seam between vertical upper top board, grid, the light fixture and transversely middle top board and grid, grid and the light fixture, this just has higher requirement to skill and the skill level of workman's operation; And needing a large amount of attaching partss, fastener and installation smallclothes, the workman need to carry out a large amount of duplication of labour onboard; In addition, secondary skeleton weight is very large, and installation difficulty is relatively large, needs leveling during installation, wastes time and energy, and labour intensity is large, inefficiency.
Summary of the invention
The utility model relates to roof construction in a kind of railcar modularization of simple in structure, lightweight, easy for installation, time saving and energy saving, high efficiency, overcomes the deficiencies in the prior art.
Roof construction in the railcar modularization of the present utility model, comprise crossbeam, middle top board, lamp bracket, supply grille, a plurality of crossbeams are arranged parallel to each other, two bank light framves be parallel to each other the below that is installed in each crossbeam and with mutually vertical setting of crossbeam, middle top board is arranged on the below of crossbeam and between two bank light framves, supply grille is installed in the outside of lamp bracket; The position is provided with the middle handrail mount pad in the middle of on crossbeam; Be provided with the side armrest mounting seat in crossbeam upper end position.
Roof construction compared with prior art has the following advantages in the railcar modularization of the present utility model:
A) formed modular construction, brevity and lucidity is avoided the repeated labor of the single installation of scattered parts, increases work efficiency, and saves cost of labor.
When b) installing on the car, quick and easy, reduce the upper operation easier of workmen's coach, handled easily.
C) backform piece operation under car in, the top forms the homogeneity of seam, Improving The Quality of Products in the lifting.
D) cancel secondary skeleton, be conducive to the whole lightweight of vehicle.

The specific embodiment
Shown in Fig. 1～8: 1 is crossbeam, totally four, forms a Zhong Ding unit.Crossbeam 1 can be aluminium alloy extrusions and makes, and its section leaves chute and is used for arranging erection bolt (referring to Fig. 3,4,5).Four crossbeams 1 are arranged parallel to each other, and 4 is lamp bracket, two bank light framves 4 be parallel to each other and be mounted by means of bolts on each crossbeam 1 the below and with crossbeam 1 mutual vertical setting.
The position is provided with middle handrail mount pad 6 in the middle of on the crossbeam 1 at interval; Crossbeam 1 upper end position at the interval is provided with side armrest mounting seat 5.Each armrest mounting seat is fixed on the crossbeam 1 with square nut and hex bolt, plain cushion, spring chair.
Form roof construction in the modularization behind above-mentioned each assembling parts, during the city rail vehicle assembling, do not need scattered parts are assembled one by one, get final product and only the top disposable installation of composition in the modularization need be got on the bus, greatly save the time, avoided the duplication of labour on the car, reduced the ceiling task difficulty.
