Technical Field

The invention relates to the technical field of rail vehicles, in particular to a novel rail vehicle roof framework.

Background

The rail car (including trailer, the same below) is the main transport tool for the construction departments of railway equipment maintenance, overhaul, capital construction and the like to execute tasks. The rail car is divided into a heavy type rail car and a light type rail car, and can be withdrawn from a line at any time by passengers, so that the rail car is called a light rail car; the railway car is called a heavy-duty railway car, and passengers cannot withdraw the railway at any time.

In order to avoid the phenomenon that the gap is too large after the top plate is welded, the rail car roof framework is usually assisted by an auxiliary tool during installation and welding, but the conventional auxiliary working volume is relatively too large, so that the rail car roof framework is not suitable for any occasions.

The invention has the beneficial effects that:

1. this novel rail vehicle roof skeleton through installation detachable coupling mechanism between two roofs, through two roof of the convenient take-up of adjusting bolt on the coupling mechanism, has effectually prevented the too big problem in gap when the welding between the roof.

2. This novel rail vehicle roof skeleton through set up the bracing piece in the roof bottom, has consolidated the connection between the roof, further prevents to appear the problem in gap easily between the roof.

3. This novel rail vehicle roof skeleton through set up these two kinds of connected modes of sliding sleeve or stopper in the roof bottom, all is the installation welding that makes things convenient for the bracing piece, through spout and sliding sleeve or tooth's socket and stopper, all conveniently adjusts the position of installation.
