Abstract
The utility model discloses a roof transition unit of a railway vehicle. A transition unit is connected between a flat top and an arc top to reinforce the structure rigidity and meet arrangement requirements for the bearing and mounting of an air-conditioner on vehicle body made of aluminum alloy. The transition unit mainly comprises a U-shaped hollow profile connected with the arc top and a multi-stage H-shaped hollow profile connected with the flat top, wherein the U-shaped hollow profile and the multi-stage H-shaped hollow profile are connected with each other to form a box-shaped structure. Two ends of the transition unit are respectively connected with the arc top and the flat top so as to finally form a stable transition and connection structure, therefore, not only the requirements for the bearing design of the air-conditioner mounted on the flat top can be met, but also the height difference of different design structures of roofs can be taken into consideration.
Description
Technical field
The utility model is the improvement at connection structure between the flat-top at car body top and the arc top, and Stability Design and realization draining smoothly to realize the vehicle top air conditioner carrying platform belong to mechanical manufacturing field.
Background technology
The present guideway vehicle of place in operation, interior environment system is installed on roof at large and rainwater is set, snow-broth compiles discharging mechanism.The roof structure of generally being taked is, for installing an air-conditioner smoothly and assisting and establish the mounting groove that delivery piping need be offered the indent formula at place, arc top.
Because the roof of existing guideway vehicle ad hoc is not provided with the air-conditioning carrying platform, so formed condensed water is difficult to discharge during operation of air conditioner, and then the leakage phenomenon that has influence on the refrigeration of interior environment system and cause the roof position.
Offer the air-conditioning carrying platform specially at roof, can occupy the space at top, a part of guest room again.
Having common improved mode now is, in the air-conditioning installation position roof is set to flat-top, arc top respectively, and air-conditioning directly is carried on the flat-top position.But flat-top and arc lack necessary being connected between the top, can directly cause the decline and the fugitiveness of structural strength.
The utility model content
Guideway vehicle roof transition element described in the utility model is to solve above-mentioned prior art defective.
Its design goal is, takes to be connected a transition element between flat-top and the arc top, with the reinforced structure rigidity, satisfy the needs that are provided with of aluminum alloy bodywork air-conditioning carrying installation.
Another design goal is, with the connection of multistage H type hollow material, satisfies different height fall between arc top and the flat-top.
For realizing above-mentioned design goal, described guideway vehicle roof transition element mainly includes:
The U type hollow material that connects the arc top,
Connect the multistage H type of flat-top hollow material,
U type hollow material is connected with multistage H type hollow material and forms box-structure.
As above-mentioned essential characteristic, connect arc top and flat-top respectively from two ends by transition element, with final formation pulsation-free transition connection structure, both can satisfy air-conditioning and be installed on flat-top carrying designing requirement, can also take into account the height fall of different roof project organizations simultaneously.
Comparatively preferably transition element connection structure and mode are, the end of U type hollow material is provided with inboard inserted sheet, and the inserted sheet of inboard inserted sheet and multistage H type hollow material end is pegged graft opposite to each other.
Can be refined as with the flat-top connection structure, the end of multistage H type hollow material is provided with, the evagination connecting panel that overlaps mutually with flat-top.
Can be refined as with the connection structure on arc top, the end of multistage H type hollow material is provided with, and pushes up the connecting panel of overlap joint mutually with arc.
Be improving and arc top connection stability, is that the exterior contour of U type hollow material pushes up consistent with arc for the improvement project of U type hollow material.
For improving the structural rigidity of multistage H type hollow material, the inside of multistage H type hollow material is provided with the dividing plate that several be arranged in parallel.
Connect the intensity that the back forms transition structure for optimizing further, U type hollow material is connected with arc top overlap joint.
After finishing overlap joint and connecting, U type hollow material and multistage H type hollow material also can be by the welding formula structures that forms as one.
Content to sum up, described guideway vehicle roof transition element has the following advantages:
1, can satisfy the setting of vehicle top air conditioner installed platform, the arc top realizes that with flat-top stable transition is connected, and rigidity is bigger.
2, the multistage H type hollow material of transition element, the arc top that can satisfy the differing heights drop is connected with flat-top.
Description of drawings
Now in conjunction with the following drawings the utility model is described further
Fig. 1 is the scheme drawing of guideway vehicle roof;
Fig. 2 be among Fig. 1 A-A to the transition element scheme drawing that cuts open after showing;
As depicted in figs. 1 and 2, arc top 1, arc top bonding jumper 2, U type hollow material 3, inboard inserted sheet 4, multistage H type hollow material 5, evagination connecting panel 7, dividing plate 8, inserted sheet 10, connecting panel 11, flat-top 12.
The specific embodiment
Transition element includes U type hollow material 3 that connects arc top 1 and the multistage H type hollow material 5 that connects flat-top 12, and U type hollow material 3 is connected with multistage H type hollow material 5 and forms box-structure.
The end of U type hollow material 3 is provided with inboard inserted sheet 4, and after inboard inserted sheet 4 was pegged graft opposite to each other with the inserted sheet 10 of multistage H type hollow material 5 ends, U type hollow material 3 and multistage H type hollow material 5 were by the welding formula structure that forms as one.
The end of multistage H type hollow material 5 is provided with, the evagination connecting panel 7 that overlaps mutually with flat-top 12.The end of multistage H type hollow material 5 also is provided with, and pushes up the 1 evagination connecting panel 11 that overlaps mutually with arc.
It is 1 consistent that the exterior contour of U type hollow material 3 and arc push up, and U type hollow material 3 is connected with arc top 1 overlap joint.
The inside of multistage H type hollow material 5 is provided with several dividing plates that be arranged in parallel 8.
