Abstract
The utility model relates to a top cover of a metro rail vehicle, which is in an independent structure, so that an attractive appearance and the design requirements of convenient installation and detachment are balanced. The top cover and a vehicle top structure are in smooth transmission, so that the air resistance when the vehicle runs is reduced. The top cover comprises a cover body which is arranged on a vehicle top through a bolt, the cover body is provided with a streamlined outline which is the same with the vehicle top, and the installed cover body and the vehicle top are in smooth transition. After the top cover and the vehicle top are installed and connected, the overall streamlined appearance of the vehicle top can be maintained, and simultaneously lower wind resistance can be ensured. The connecting structure of the top cover and the vehicle top is easy to install and detach, so that the overhaul of the vehicle is facilitated.
Description
Technical field
The utility model relates to a kind of overhead guard that the underground railway track vehicle roof is installed that is applied to, and belongs to machine manufacture and traffic and transport field.
Background technology
Domestic city track traffic has at present obtained very fast development, and what the driver's cab of existing railcar adopted usually is the glass-felt plastic hood structure, though comparatively profile is comparatively attractive in appearance, in installation process since locating point too much, difficulty of construction is very big.
What also have to adopt is whole overhead guard structure, and this type of one-piece construction is easy to install and the location, but breaks down or during regular maintenance, whole overhead guard need be disassembled when vehicle, thus comparatively waste time and energy, the work load of operating personal is bigger.
In view of this special present patent application that proposes.
The utility model content
The overhead guard of underground railway track vehicle described in the utility model, its design goal are to adopt a kind of absolute construction for the problem that solves above-mentioned prior art existence, to realize taking into account designing requirement aesthetic in appearance and installation, convenient disassembly.
Design goal also is, seamlessly transits the air resistance when being beneficial to reduce vehicle operating between overhead guard and the roof structure.
For realizing above-mentioned design goal, the overhead guard of described underground railway track vehicle mainly includes:
Be installed on the cover body of roof by bolt, cover body has the stream line pattern exterior contour identical with roof, and cover body and roof after the installation seamlessly transit.
As above-mentioned basic scheme feature, overhead guard and roof can keep roof single-piece streamlined appearance after installing and being connected, and the while also can guarantee lower windage.
The connection structure of overhead guard and roof is easy to Assembly ﹠Disassembly, helps vehicle and overhauls.
For improving the design performance that reduces windage, further prioritization scheme is that the vertical height of described cover body is between 65 to 256 millimeters.
For reducing windage and the appearance effects that the external connection structure forms, cover body is provided with several and is used for carrying out bolted, vertical positioning groove with roof.
For improving the light-weight design and the mechanical strength of cover body self, described cover body integral body has thin-wall construction, and its inboard is provided with several and strengthens gusset.
For being that the innovative approach of refinement is, in the cover body inboard, several are strengthened gussets and form fenestral fabric along horizontal and vertical being staggered,
For improving whole non-deformability and be connected fastening performance,, staggered 2 splicing positions of strengthening between the gussets are rounding structures.
Also the spacing between per 2 described reinforcement gussets can be set at 500 to 600 millimeters simultaneously.
The excessive cover body structure of destroying of exerting oneself when avoiding installing, the bolted place in the positioning groove bottom is provided with pre-embedded steel slab.
In sum, the advantage that has of the overhead guard of the utility model underground railway track vehicle is:
1, adopts the overhead guard of absolute construction, be easy to install and the location, convenient disassembly and help overhaul of the equipments.
2, the coordinating and unifying attractive in appearance of overhead guard and roof has higher aesthetic feeling.
3, seamlessly transit between overhead guard and the roof structure, the air resistance when reducing vehicle operating is arranged.
