Multifunctional vehicle roof edge beam for railway vehicle

Abstract

A multifunctional vehicle roof edge beam for a railway vehicle comprises a long-strip-shaped body with radian. The multifunctional vehicle roof edge beam is characterized in that a connector suitable for being connected with an air conditioner frame in a lapped mode is formed in the upper end of the body, and two long-strip-shaped C-shaped grooves are formed in the back of the body and used for installing an air conditioner diversion cover installation base through bolts; two C-shaped grooves are formed in the inner side of the body and used for hoisting built-in lazy arms through bolts; a connector suitable for being connected with the side wall of a vehicle body in a lapped and welded mode is formed in the lower end of the body. According to the multifunctional vehicle roof edge beam, the two C-shaped groove structures are integrated on the back, the diversion cover installation base is made of extrusion sections and is connected with the C-shaped grooves through the bolts, zero welding is achieved, and it is not required to polishing welding seams. The installation base is provided with a transverse long circular hole, and the installation size of a diversion cover can be adjusted conveniently. The multifunctional edge beam has the advantages that modular design of vehicle roof equipment can be achieved easily, the installation efficiency is high, the appearance of the diversion cover can be guaranteed easily, cost is reduced obviously, and benefits are increased obviously.

Description

technical field [0001] The invention relates to a rail vehicle multifunctional roof side beam, belonging to the technical field of rail vehicle body structures. Background technique [0002] At present, the installation methods of the internal and external parts of the intercity EMU roof are complex, especially the exterior of the roof is welded with a large number of welded parts, the welding and grinding workload is heavy, the modular design requirements are not considered, and the installation efficiency is low. [0003] For example, the mounting seat of the air conditioner shroud is welded on the roof. There are 60 seats in a car, and the seats span the weld seam of the roof. Before welding the seat, the mounting part of the roof needs to be polished, and the grinding work will be increased. The amount and welding workload, and it is difficult to adjust the installation size of the air-conditioning shroud after the seat is welded. Contents of the invention [0004] Th...
