Middle beam reinforcing structure for rail wagon and wagon frame

Abstract

The invention discloses a middle beam reinforcing structure for a rail wagon and a wagon frame. Problems that in the prior art, a middle beam inner cavity structural part is prone to slipping off, andassembling efficiency is low are solved. Strength of a middle beam can be effectively improved; and the middle beam inner cavity part is prevented from slipping off and maintenance operation can be performed conveniently. The middle beam reinforcing structure for the rail wagon comprises a bottom plate, the bottom plate is arranged in a width direction of the middle beam, a reinforcing plate capable of being embedded into a hollow position of a lower flange of the middle beam is arranged on the bottom plate, and the bottom plate is detachably connected with the lower flange of the middle beam.

Description

technical field [0001] The invention relates to the field of railway freight cars, in particular to a middle beam reinforcement structure and a vehicle frame for railway freight cars. Background technique [0002] As a manufacturing powerhouse in my country, the export of railway wagons is also a part of it. The center girder is the key load-bearing part of the whole railway wagon, which needs to have a set rigidity. The existing center girder does not need to carry many parts inside, so as to ensure the structural strength of the center girder Under the premise that the lower flange of the center sill usually has multiple hollows, the measures taken by general railway freight cars are to weld reinforcing plates on the lower surface of the lower flange of the center sill (excluding the hollows) to increase the rigidity. [0003] For some countries, due to the structural setting of railway freight cars, these countries require that the braking system of railway freight cars ne...

AI Technical Summary

Problems solved by technology

[0004] First, the strength of the center sill is limited, so that some brake components such as brake shoe clearance adjusters and brake rods cannot be installed in the inner cavity of the center sill, and only another space can be found for installation. At present, the method used is to install the When the bogie is pushed out, it is conducted from one end of the car body to the inner cavity of the center sill. Such a structural arrangement makes the assembly efficiency low;

[0005] The second is that there is an accidental detachment of the inner cavity structural parts of the center beam. If it falls off during the driving process, it will directly affect the driving safety of the railway train;

[0006] Third, if a whole reinforcing plate is installed on the lower flange of the center sill, the lower flange of the center sill will be blocked, and there is no auxiliary equipment for outdoor work, so it cannot be operated on site, and the braking system needs frequent maintenance. But after being blocked, the vehicle can only be pushed into the maintenance workshop to separate the car body and bogie for maintenance, which requires a lot of auxiliary equipment, long solution period and low operation efficiency
