Description

A kind of crossbeam carrying structure of well hole car and the connection structure with vehicle body side wall thereof
Technical field:
The utility model relates to a kind of Container Transport special purpose freight car key structure, particularly about a kind of crossbeam carrying structure of loading container well hole car.
Background technology:
At present, domestic have a kind of double stacked container car, the assembly welding structure that the beam structure of its concave bottom frame is made up of upper cover plate and crossbeam lower cover, and crossbeam lower cover and side wall bottom side rail butt welding, connect two curb girders; Upper cover plate then covers on the attachment weld on lower cover and two curb girders, and together with crossbeam lower cover, two bottom side rail assembly weldings, this beam structure Problems existing one is because freight container vertical load is directly passed to side wall bottom side rail by beam structure, cause side wall bottom side rail and the stress raisers between crossbeam lower cover and the attachment weld of bottom side rail, cause the fatigue damage of structure to cause structural failure and destruction simultaneously.Two is that vehicle is in operation, and easily vibrates in the middle part of crossbeam, and in the middle part of crossbeam, quality is larger because section of beam rigidity is weak, and the vibratory force of generation is also larger, causes the damage easy to crack of the weld seam of crossbeam lower cover and two bottom side rails.
Summary of the invention:
In order to solve the problems referred to above in known technology, the purpose of this utility model is to provide a kind of well hole car crossbeam carrying structure that can significantly improve the loading container of intensity and fatigue reliability.Its technical scheme is as follows:
A kind of crossbeam carrying structure of loading container well hole car, comprise upper cover plate and trough girder, its gordian technique is also to comprise dihedral load bearing seat, and upper cover plate is wide U-shaped by crimping, upper cover plate comprises left facade, right facade and bottom surface, and bottom surface and trough girder interlock assembly welding; Dihedral load bearing seat is sector hollow section steel casting, and dihedral load bearing seat comprises vertically end and horizontal ends, and vertically end arranges embedding mouth.
A kind of crossbeam carrying structure of loading container well hole car and the connection structure of vehicle body side wall, its gordian technique is that vehicle body side wall comprises framed side wallboard, side wall head tree and side wall L shape lower-edge beam, L shape lower-edge beam comprises vertical plane and horizontal surface, the embedding mouth of the vertical end of dihedral load bearing seat and the embedded assembly welding in side wall head tree bottom of side wall, the horizontal ends of dihedral load bearing seat docks assembly welding with the both ends of trough girder, and dihedral load bearing seat is riveted with the vertical plane of side wall L shape lower-edge beam and the left facade of upper cover plate and right facade respectively by rivet.
The upper plane in the vertical direction of described upper cover plate bottom surface lower plane and side wall L shape lower-edge beam horizontal surface is provided with the vertical gap of 3mm ~ 8mm.
Compared with existing known conventional double container car beam structure, Advantageous Effects of the present utility model is:
1, the utility model adopts the combination of wide U-shaped upper cover plate and dihedral load bearing seat, the framed side wallboard and the direct of lateral column that realize the beam structure two ends car body concave bottom frame sidewall structure very powerful with vertical stiffness are welded, side wall is connected with underframe, car body vertical load can pass to rapidly sidewall structure and whole body construction, realize effective transmission of stress, make car body distribution of stress be tending towards even, the structural fatigue avoiding stress to concentrate causing lost efficacy.
2, cast steel dihedral load bearing seat of the present utility model is the attaching parts between beam structure trough girder and sidewall structure lateral column, the underframe of car body cross-sectional plane herein and side wall is made to form through U-shaped structure by dihedral load bearing seat, the section of U-shaped is closed square-section box beam, improves the integral rigidity of cross-car structure.Further increase by dihedral load bearing seat and the riveted joint of side wall bottom side rail the structural reliability that crossbeam carrying structure is connected with car body simultaneously.
3, the vertical gap arranged between upper cover plate and side wall L shape lower-edge beam horizontal surface, can avoid making load directly pass to side wall lower-edge beam because upper cover plate obtains local deformation under the effect of vertical static weight or live load, cause the generation that stress is concentrated.
4, the connection of its crossbeam of the utility model and car body concave bottom frame side wall have employed and welds riveting mixed system, and structural reliability is high.
