The invention discloses a top plate and air duct installation assembly inside a roof of a railway vehicle. The assembly comprises a plurality of joists (2), hoisting seats (1), an air duct (3) and a top plate (4). The joists (2) are distributed in parallel in the length direction of a vehicle body, and the two ends of each joist (2) are connected with the top of the vehicle body through independent hoisting seats (1) respectively. The upper end of each hoisting seat (1) is connected with the top of the vehicle body, and the lower end of each hoisting seat (1) is connected with one end of the corresponding joist (2). The air duct (3) is fixed above the joists (2). The top plate (4) is fixed below the joists (2). The method of sharing the hoisting seats and layered hoisting is adopted in the assembly, and air duct installation points and top plate installation points are both integrated in sliding grooves of the joists; the independent hoisting seats facilitate arrangement of the joists; the sliding grooves are formed in three faces of each joist, so installation is convenient, the problem that the space on the roof of the vehicle is limited is solved successfully, the total weight is decreased, and modular quick installation can be achieved.
