Abstract

The invention discloses a new rail vehicle roof frame, which comprises two mounting plates, the outer walls of the opposite sides of the two mounting plates are fixed with connecting rods through bolts, and the same connecting rod is fixed with bolts between the two connecting rods. As for the fixed plate, the outer walls on the opposite sides of the two mounting plates are fixed with slide rails by bolts, and the inner walls of the two slide rails are respectively slidably connected with a first top plate and a second top plate, and the two sides of the first top plate and the second top plate are The side outer walls are provided with mounting holes, the outer walls on both sides of the first top plate and the second top plate are provided with connecting mechanisms, and support rods are welded on the fixed plates, and the connecting mechanisms include a first connection box and a second connection box. box. The present invention installs a detachable connection mechanism between the two top plates, and the two top plates are conveniently tightened by adjusting bolts on the connection mechanism, effectively preventing the problem of excessive gap between the top plates during welding.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a novel rail vehicle roof frame. Background technique [0002] Rail cars (including trailers, the same below) are the main means of transportation for construction departments such as railway equipment maintenance, overhaul, and infrastructure construction to perform tasks. There are two types of railcars: heavy and light. Those that can be withdrawn from the line by passengers at any time are called light railcars; those that cannot be withdrawn from the line by passengers at any time are called heavy railcars. [0003] Auxiliary tools are usually used to assist in the installation and welding of the rail car roof frame to avoid excessive gaps after the roof is welded. However, the existing auxiliary work volume is relatively large and is not suitable for any occasion. Contents of the invention [0004] The object of the present invention is to propose a novel rail vehi...
