Embodiment Construction
[0017] Such as figure 1 As shown, a locomotive longitudinal beam has a longitudinal beam main body, the longitudinal beam main body is symmetrically designed with the longitudinal central axis, and the upper part of the longitudinal beam main body is a horizontal beam 7, and the two ends of the horizontal beam 7 are respectively provided with oblique slant protruding outwards below. To the beam 8; the top surface of the horizontal beam 7 is provided with two first C-shaped grooves 1 with upward openings, and the bottom of the inclined beam 8 is provided with a second C-shaped groove 3 with downward openings; the two inclined beams are opposite to each other. The inner surfaces of the two inclined beams 8 are respectively provided with the first side beams 4 protruding from the central axis of the main body of the longitudinal beams, and the outer sides of the bottom ends of the two inclined beams 8 are respectively provided with the second side beams 2 protruding outward; above...

The invention relates to urban rail vehicles, in particular to a locomotive longitudinal beam and a tramcar provided with the locomotive longitudinal beam. The locomotive longitudinal beam is provided with a longitudinal beam body which is symmetrically arranged about the longitudinal axis. A horizontal beam is arranged on the upper portion of the longitudinal beam body. The two ends of the horizontal beam are respectively provided with an inclined beam extending outwards to the lower portion; the opposite inner sides of the two inclined beams are respectively provided with a first edge beam extending from the central axis of the longitudinal beam body and the outer side faces of the bottom ends of the two inclined beams are respectively provided with a second edge beams extending outwards. The tramcar comprises a tramcar top frame, an air flue grating, a handrail and an illumination lamp. A clamping opening is formed in the installation end of the air flue grating. The air flue grating, the handrail and the illumination lamp are respectively installed on the locomotive longitudinal beam. According to the locomotive longitudinal beam and the tramcar provided with the locomotive longitudinal beam, installation connectors of the illumination lamp, the air flue grating and the handrail are arranged on the longitudinal beam in a unified mode and the installation connectors are simplified.
Description
technical field [0001] The invention relates to an urban rail vehicle, in particular to a locomotive longitudinal beam and a tramcar installed with the longitudinal beam, and is especially suitable for low-floor modern tramcars. Background technique [0002] At present, various parts need to be installed on the roof of modern low-floor trams, such as lighting fixtures, air outlet grilles, and handrails. Skeleton connection, such an installation method makes the layout of the roof frame or the built-in secondary frame complicated, and the installation and positioning are difficult. During installation, a large number of installation interfaces and mounting seats are required, and the number of fasteners required is large, which is not easy to install and maintain. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art, to provide a locomotive longitudinal beam and a tram installed with the longitudinal beam, t...
