Abstract
A platform-free aluminum alloy roof structure of an urban subway vehicle is characterized in that a whole roof integrally adopts a middle roof plate double-side automatic welding structure made of a full aluminum alloy material and is integrally composed, a unit mounting seat is welded on the flat roof, an air supply port and an air return port are formed in the roof, a sealing frame is welded on the inner side of the opening, a sliding chute is formed in a full aluminum alloy profile of the roof, and a wire laying pipe is welded on the upper surface of the middle roof plate and a wire binding sliding chute is formed in the upper surface of the middle roof plate. The platform-free aluminum alloy roof structure is formed by welding the full aluminum alloy profile, and the cross section of the whole vehicle is consistent, so that the rigidity of the whole vehicle is uniform, and the region of stress concentration is smaller. An air conditioning unit platform doesn't exist, so that part of welding is reduced, ponding is not easy to occur, and simultaneously, the adjustment of an air conditioning unit position is facilitated; the roof is free of the air conditioning unit platform, so that the whole roof structure is consistent, and condensed water and rainwater flow directly to the roof surface and are drained to the ground by an end drain pipe along the eaves. For the roof free of the unit platform structure, a transition structure between the unit platform and the arc roof is saved, so that the weight of the arc roof free of the unit platform structure is relatively reduced to about 100 kg under the premise of the same limit.
Description
Technical field
The present invention relates to a kind of railcar aluminium alloy extrusions roof structure design.
Background technology
Existing vehicle aluminium alloy extrusions roof constructed of aluminium is provided with air-conditioning unit platform structure, and among the recessed roof of air-conditioning unit platform, its section is distinguished to some extent at air conditioning area and other position.Therefore rigidity of the vehicle inequality, especially declines in the guest room of air-conditioning unit position door field strength, is prone to area of stress concentration.And easily produce endurance crack in variable section commissure, cause unit land regions to occur infiltration, thereby affect vehicle life span.The ponding of land regions is difficult for discharge simultaneously, easily leaks.
Summary of the invention
The object of the invention is to solve the phenomenon that endurance crack appears in railcar aluminium alloy extrusions roof structure for a long time, improve drainage performance.
For achieving the above object, the invention provides a kind of subway vehicle without platform aluminum alloy roof structure, it is characterized in that: whole roof all adopts the two-sided automatic welding structure of middle top board of elongated aluminum alloy materials, roof entirety is synthetic, on flat-top, weld unit mount pad, be provided with air outlet and return air inlet at roof, at all welded seal frames of the opening part inner side of air outlet and return air inlet, roof aluminium alloy extrusions inside is with chute, spool and binding chute under middle cover top surface welding.
The present invention compare background technology produce good effect as follows:
(1) structural strength and rigidity
Adopt elongated aluminium alloy extrusions to be welded without platform truck roof construction, car load section is consistent, and therefore the rigidity of car load is even, and areal of stress concentration is less.Owing to there is no air-conditioning unit platform structure, reduce a part of weld seam, and be difficult for producing ponding, be conducive to the adjustment of air-conditioning unit position simultaneously.
(2) conditioned area ponding discharge
Roof is without air-conditioning unit platform, and roof integral structure is consistent, and its condensed water and rainwater flow directly to roof surface, and is discharged to ground along rain eaves by end drain hose.
The roof of inorganic group platform structure, saves the transition structure between machine group platform and circular arc roof, therefore under identical gauge prerequisite, about the relatively at least light 100Kg of the circular arc roof weight of inorganic group platform structure.
Brief description of the drawings
This aspect of Fig. 1 roof structure sectional schematic diagram;
Fig. 2 is air conditioner group place, this aspect floor plan schematic diagram;
Fig. 3 is that air conditioner group place, this aspect section is arranged schematic diagram.
Detailed description of the invention
As shown in Figure 1, the 1st, car roof side-beam, the 2nd, middle top board I, the 3rd, middle top board II, the 4th, middle top board III, whole roof all adopts middle top board I, middle top board II, the two-sided automatic welding structure of middle top board III of elongated aluminum alloy materials, and roof entirety is synthetic.
As shown in Figure 2 and Figure 3, on roof, weld unit mount pad 5, be provided with air outlet 6 and return air inlet 7 at roof, spool 8 and binding chute 9 under middle top board III upper surface welding, in inner side, air outlet place welding air outlet sealing frame 10, in inner side, return air inlet place welding return air inlet sealing frame 11.
Aluminium section bar section thickness in air-conditioning unit mount pad Position Design is greater than other positions, meets the intensity of air-conditioning unit to roof and the requirement of air-conditioning unit seat welding performance.
Roof section is consistent in car load scope, plans as a whole the installation requirements of roof interior trim equipment at the design initial stage, and roof aluminium section bar carries chute, avoids roof large-area welding chute and the welding deformation that causes.
This kind of whole roof section of structure is consistent, and car load roof strength and rigidity are even, avoids the variable section of air-conditioning unit position of platform to occur, the uneven and solder joint fatigue crackle that causes of the intensity, rigidity that solve vehicle top air conditioner unit position of platform.Meanwhile, its condensed water and rainwater flow directly to roof surface, and are discharged to ground along rain eaves by end drain hose, and the roof that solves organic group platform structure is more and be prone to ponding and occur leak source at unit land regions weld seam.
By the design of inorganic group platform roof, successfully solve railcar aluminium alloy extrusions roof structure for a long time and occur the phenomenon of endurance crack, and improve the drainage performance of vehicle.This invention, by the rain test of vehicle and the checking of the actual operation of Harbin subway Line 1, is applied in the project such as No. 2 lines of Changchun subway 1 & and No. 4 lines of Wuhan subway 3 & successively.
