Abstract
The utility model provides a sealed frame type integrated impact base for a railway transport car. The sealed frame type integrated impact base is formed by an impact base body, a wearing plate and an adjusting base plate. The impact base body is molded in an inblock cast mode. The opening of the impact base body is in a horn shape. An impact base car coupler supporting face is arranged in the impact base body and is of an integrated sealed frame type structure. The adjusting base plate is arranged on the impact base car coupler supporting face in a welded mode. The wearing plate is located on the adjusting base plate, and the wearing plate and the adjusting plate are welded into a whole. The sealed frame type integrated impact base is applicable to E/F car couplers of the AAR standard; through the sealed frame type integrated impact base, vertical supporting and horizontal force transmission of the car couplers can be achieved, and the height of the car couplers can be adjusted; through optimization design of the opening of the impact base body, the angle of the opening of the impact base body is enlarged, the sealed frame type integrated impact base increases the angle of swing of the car couplers allowed by a car body structure when the railway transport car passes through a small curve and an S-shaped curve and meets the running requirements of the railway transport car for passing through the curves.
Description
Technical field:
The utility model relates to railway traffic technical field, and the striker that relates in particular to railroad boxcar coupler and draft gear is manufactured field, specifically, is a kind of railroad boxcar sealing frame type entirety striker.
Background technology:
Railroad boxcar is made up of multiple compartments, between compartment, connects by coupler and draft gear, to realize the transmission of longitudinal force between vehicle, ensures travelling of railroad boxcar.Coupler and draft gear be realize that vehicle interconnects, transmitting tractive power or compressive force and to relax the most basic of longitudinal impact be also most important parts, coupler and draft gear is installed on the central sill of railroad boxcar, and it is mainly made up of hitch, striker, hook tail frame and energy disperser.Because railroad boxcar needs the goods that domestic shipping weight is larger, therefore the load-carrying parts of railroad boxcar just seem particularly important.Striker is as one of parts very crucial on railroad boxcar central sill, bear the transmission of longitudinal traction load in vehicle operating process, according to hitch type and vehicle structure, striker can be divided into two kinds of inblock cast and steel plate installed-weldeds, steel plate installed-welded welding job amount is large, efficiency is low, and the parts after welding are prone to torsional deflection, is difficult to proofread and correct; According to central sill connection mode, can be divided into riveted type and welded type.
Due to the raising of railroad boxcar load-carrying and speed, load-carrying part requirement is improved, need to be optimized design to load-carrying parts, therefore urgently impact seat is optimized, the striker that need to design that structure is more reasonable, its scantling of structure and structural strength more can meet lorry Operational requirements.
Summary of the invention:
The purpose of this utility model is to provide a kind of railroad boxcar sealing frame type entirety striker, its reasonable integral structure, and its scantling of structure and structural strength meet the requirement of lorry operation, have increased adjustment backing plate, can realize hitch height adjustment.
To achieve these goals, the utility model adopts following technical scheme:
The utility model provides a kind of railroad boxcar sealing frame type entirety striker, this sealing frame type entirety striker is made up of striker, wearing plate and adjustment backing plate, in striker, be provided with striker hitch bearing surface, on striker hitch bearing surface, be provided with adjustment backing plate, adjusting backing plate is welded on striker hitch bearing surface, wearing plate is positioned at the top of adjusting backing plate, is welded as a whole with adjustment backing plate.
Compared with prior art, the beneficial effect the utlity model has is:
1, the utility model adopts inblock cast striker, forms rational carrying structure, makes full use of the load-carrying capacity at each position, realizes the transmission of longitudinal direction of car drawbar load.
2, the hitch bearing surface of striker described in the utility model is integrally closed frame type structure.Greatly increase and the anti-vertical load strength and stiffness of the end carriage of this programme striker assembly welding, improved car load strength at repeated alternation and life-span.
3, the utility model adopts the striker of horn opening, impact seat opening is optimized design, opening reaches 320mm, increase striker opening angle, angle is 10 °-20 °, while having improved vehicle by little curve and S type curve, body construction allows the angle that hitch swings, and meets vehicle by curve motion requirement.
4, the utility model adopts has increased adjustment backing plate between striker and wearing plate, and setting range reaches 13mm, can realize the height adjustment of hitch in certain specialized range.
5, the utility model adopts wearing plate, is convenient to abrasion and arrives repairing and the replacing after limit, accomplishes zero damage of impact seat.
Brief description of the drawings:
Fig. 1 is the block diagram of this sealing frame type entirety striker;
Fig. 2 is the front view of this sealing frame type entirety striker;
Fig. 3 is the birds-eye view of this sealing frame type entirety striker;
Fig. 4 is the left view of this sealing frame type entirety striker.
Detailed description of the invention:
Contrast Fig. 1-Fig. 4, the utility model provides a kind of railroad boxcar sealing frame type entirety striker, this sealing frame type entirety striker is made up of striker 1, wearing plate 2 and adjustment backing plate 3, striker 1 is integral casting forming, and the Intensity Design of striker 1 meets the longitudinal traction load that is not less than 3375kN.On striker 1 rear portion internal chamber wall, be provided with and strengthen gusset 6, to strengthen the intensity of striker 1.Striker open end 5 forms tubaeform, and striker 1 opening can reach 320mm, and horn opening angle is 10 °-20 °, the angle that this angle forms for horn opening inwall 7 and striker 1 rear portion internal chamber wall 8.The structure design of striker 1 meets little curve motion needs, and intensity meets 10000t and organizes into groups needs with Truck.In striker 1, be provided with striker hitch bearing surface 4, striker hitch bearing surface 4 is integrally closed frame type structure, makes to be strengthened with the anti-vertical load strength and stiffness of the end carriage of its assembly welding.On striker hitch bearing surface 4, be provided with the adjustment backing plate 3 for adjusting hitch height, adjust backing plate 3 and be welded on striker hitch bearing surface 4, wearing plate 2 is positioned at the top of adjusting backing plate 3, is welded as a whole with adjustment backing plate 3.It is to be convenient to wearing plate 2 abrasion to arrive repairing and the replacing after limit that wearing plate 2 is installed on adjustment backing plate 3, accomplishes zero damage of impact seat 1.Adjustment backing plate 3 between striker 1 and wearing plate 2, its setting range reaches 13mm, can realize the height adjustment of hitch in certain specialized range.
