The invention provides a top connecting structure, and belongs to the technical field of rail transit. The top connecting structure comprises a first hoisting bracket, a first profile, a second hoisting bracket, a second profile and a lamp bracket. One side of the first hoisting bracket is provided with the first profile for accommodating a wire, and the lower end is provided with a first connecting plate; the second profile is arranged on one side of the second hoisting bracket, and a second connecting plate is arranged at the lower end; and the lamp bracket is mounted below the first connecting plate and the second connecting plate. According to the top connecting structure, the first hoisting bracket and the second hoisting bracket are mounted at the top of the carriage, the first hoisting bracket is connected with the side top plate, the second hoisting bracket is connected with the middle top plate, and the lamp bracket used for mounting the lamp strip accommodates the wire through the first profile and the second profile so that all parts are modularized and integrated; and a secondary framework is avoided, and thus the connecting structure at the top of the whole carriage islighter, the self-weight of the vehicle body is reduced and the requirement of light weight of the whole vehicle is met.
Description
technical field [0001] The invention belongs to the technical field of rail transit, and more specifically relates to a top connection structure. Background technique [0002] In urban rail vehicles, the interior roof (middle roof and side roof), wire ducts and light strips are mainly installed in the upper area of the car, and the three need to be fixed with the car body through the internal connection profile structure to form The connection structure of the top of the carriage. [0003] When installing the interior roof, wiring ducts and light strips in the compartment, the conventional installation method is to use the secondary skeleton to hoist the profile to install on the top of the compartment, and use the secondary skeleton as the medium to hoist the interior roof, trunking and light strips, but the secondary The frame is mostly a solid square aluminum profile structure, and covers the entire top area of the car body, which increases the weight of the car body...
