Detailed Description
The following further describes a specific embodiment of the aluminum roof structure of the urban rail vehicle according to the present invention with reference to fig. 1. The utility model relates to a city rail car aluminium system roof structure is not limited to the description of following embodiment.
The present embodiment provides a specific structure of an aluminum roof structure of an urban rail vehicle, as shown in fig. 1 to 6, the aluminum roof structure of the urban rail vehicle includes:
a top cover 1, wherein a top beam 101 with an arc-shaped section is fixedly assembled in the top cover 1;
the bottom beams 3 are distributed right below the top cover 1, and both the bottom beams 3 and the top beams 101 can be formed by welding a plurality of aluminum alloy sections;
the top cover edge beam 2 is used for erecting the top cover 1 and the bottom beam 3 and is welded with the top cover 1 and the bottom beam 3; and
and an air conditioning platform 4 fitted into an area formed between the top cover 1 and the bottom beam 3.
Specifically, the assembly adjustment is carried out on the car roof before welding, and in order to enable the car roof to reach the expected size after welding, the influence of welding deformation is reduced to a reasonable tolerance range by using a tool. The influence of welding deformation is reduced to the minimum by reasonably adjusting and using the tools of all parts;
when an aluminum alloy vehicle body is welded, the trend that the width size of the vehicle body becomes larger and the height size becomes smaller is presented, a verification process method is selected according to actual conditions to control the size before welding, and if the difference value between the size of the vehicle body before welding and the theoretical size is larger, the pre-deformation amount is reasonably selected according to the group size before welding to control the pre-deformation, so that the size after welding is within a qualified range.
