Technical field
The utility model relates to a kind of self-propelled vehicle attaching parts, relates in particular to a kind of dull and stereotyped railway carriage beam joint device.
Background technology
Flat truck case comprises longeron, in order to strengthen the stability of railway carriage, between longeron, welding is distributed with some underframe crossbeams, in prior art, the underframe crossbeam of railway carriage is provided with and is connected weldment with the intersection of longeron, by connecting the fixing of weldment, realizing being connected and fixed of longeron and underframe crossbeam, mainly there is following shortcoming in the connection weldment using in prior art:
1, connecting weldment is that line contacts with the junction of longeron, and after fixing welding, stress is large, and therefore weldment cannot adopt flash butt welding spot welding welding.
2, connection weldment and underframe crossbeam connection area are little, easily cause connection weldment plate inaccurate.
Utility model content
Technical problem to be solved in the utility model is to provide one and contributes to improve quality of connection, strengthens the dull and stereotyped railway carriage beam joint device of crossbeam bending strength.
For solving the problems of the technologies described above, the technical solution of the utility model is: dull and stereotyped railway carriage beam joint device, be weldingly fixed on the intersection of railway carriage longeron and underframe crossbeam, comprise connection channel-section steel, described connection channel-section steel one end is provided with the connection flange of the described longeron of fixing welding, and described connection channel-section steel and described connection are provided with outgate between flange; Two sidewalls of the described connection channel-section steel other end are outward extended with the reinforcement connecting portion that is welded and fixed described underframe crossbeam, and described reinforcement connecting portion is provided with transition recess with the described junction that is connected channel-section steel sidewall.
As preferred technical scheme, described connection flange is arranged at respectively on the end face of three sidewalls of described connection channel-section steel, and described outgate be arranged at described connection channel-section steel bottom surface and with described be connected channel-section steel bottom surface connect described connection flange on.
As the improvement to technique scheme, described transition recess is set to right angle mouth, and the bight of described transition recess is rounded corner setting.
Owing to having adopted technique scheme, dull and stereotyped railway carriage beam joint device, be weldingly fixed on the intersection of railway carriage longeron and underframe crossbeam, comprise connection channel-section steel, described connection channel-section steel one end is provided with the connection flange of the described longeron of fixing welding, and described connection channel-section steel and described connection are provided with outgate between flange; Two sidewalls of the described connection channel-section steel other end are outward extended with the reinforcement connecting portion that is welded and fixed described underframe crossbeam, and described reinforcement connecting portion is provided with transition recess with the described junction that is connected channel-section steel sidewall; The beneficial effects of the utility model are: utilize connection flange and longeron to be connected and fixed, forming surface connects between the two, makes Joint strenght larger; In connection channel-section steel both sides, be respectively equipped with reinforcement connecting portion, between reinforcement connecting portion and crossbeam, also forming surface is connected, and has strengthened the bending strength of crossbeam, makes railway carriage more firm simultaneously.
