The specific embodiment
Fig. 3 is the structural representation of the utility model bottom side door of gondola car hermetically-sealed construction embodiment; Fig. 4 is the left view of Fig. 3; Fig. 5 is the A-A cutaway view of Fig. 3; Like Fig. 3, Fig. 4, shown in Figure 5; The embodiment of the utility model bottom side door of gondola car hermetically-sealed construction; Comprise first lug boss 11 that downside every frame 6 inward flange positions have towards following side door 7; And second lug boss 10 that plays side door 7 outward flange positions to have towards downside every frame 6; First lug boss 11 has the interconnective first vertical sealing surface and the first inclination sealing surface towards the surface of following side door 7; Second lug boss 10 has the second vertical sealing surface and the second inclination sealing surface towards the surface of downside every frame 6, the first vertical sealing surface and the corresponding contact matching of the second vertical sealing surface, the first inclination sealing surface and the corresponding contact matching of the second inclination sealing surface.
Such scheme; On downside every frame 6, be provided with first lug boss 11; Be provided with second lug boss 10 on the side door 7 down; First lug boss 11 and second lug boss 10 be respectively to downside every frame 6, down side door 7 plays booster action, improved downside every frame 6, the rigidity of side door 7 down, strengthened the ability of resistance to deformation.In addition, through the first vertical sealing surface and the second vertical sealing surface that is in contact with one another cooperation, and be in contact with one another the sealing that cooperates between the first inclination sealing surface and the following side door of second inclination sealing surface realization and the downside every frame 6; Enlarged seal area; Improved sealing effectiveness, even under the situation of downside every frame 6 or side door 7 distortion down, also can reach seal request; Ensured normal railway freight traffic; Therefore, reduced downside every frame 6, played the frequency of maintenance of side door 7, and then reduced maintenance cost.
Particularly, based on the foregoing description, the mode in the inward flange position of downside every frame 6 through punching press forms first lug boss 11, and the protrusion direction of first lug boss 11 is towards side door 7 down.Wherein, downside every frame 6 can have doughnut-shaped steel plate to constitute, and can be trapezoidal at doughnut-shaped steel plate near the shape of position punch forming first lug boss 11, the first lug bosses 11 at interior ring edge.Certainly; Downside every frame 6 also can and be fixed on strip steel plate on the bottom side rail 9 by the steel plate of C shape and surround and form a framework; Inside edge at the steel plate of C shape stamps out a lug boss; On strip steel plate, also stamp out a lug boss, end to end formation first lug boss 11 of the lug boss of the steel plate of C shape and the lug boss on the strip steel plate.
Form second lug boss 10 in the outer edge of following side door 7 mode through punching press, and the protrusion direction of second lug boss 10 is towards downside every frame 6.Wherein, following side door 7 can be made up of a block plate, can be trapezoidal in the outward flange position of steel plate through the shape that punching press forms second lug boss, 10, the second lug bosses 10.In addition, in order to improve the rigidity of side door 7 down, also downward side door doorframe 6 direction punching presses have a raised body 8 at the middle part of above-mentioned steel plate.
Wherein, the upper base of first lug boss 11 of rectangle is the first vertical sealing surface, and a waist is the first inclination sealing surface; The upper base of second lug boss 10 of rectangle is the second vertical sealing surface; A waist is the second inclination sealing surface, the first vertical sealing surface and the corresponding contact matching of the second vertical sealing surface, the first inclination sealing surface and the corresponding contact matching of the second inclination sealing surface; To realize down the sealing between side door 7 and the downside every frame 6; This hermetically-sealed construction is the curve-seal structure, and the length of sealing surface is longer, has improved sealing effectiveness.For example, as shown in Figure 6, after side door 7 outward flanges 12 are out of shape down, still have good sealing effectiveness between following side door 7 and the downside every frame 6; As shown in Figure 7, after the outside 13 of second lug boss 10 of side door 7 is out of shape down, still have good sealing effectiveness between following side door 7 and the downside every frame 6; As shown in Figure 8, still have good sealing effectiveness between the following side door 7 after the inside 14 of second lug boss 10 of side door 7 is out of shape down and the downside every frame 6.Certainly, when first lug boss 11 of doorframe produces similar above-mentioned distortion, has above-mentioned good sealing effectiveness equally between following side door 7 and the downside every frame 6.
The utility model embodiment also provides a kind of open-top car; Comprise the compartment, the sidewall 5 in compartment is provided with downside every frame 6 (with referring to Fig. 3), and correspondence is provided with down side door 7 in downside every frame 6; The inside edge of the outward flange of following side door 7 and downside every frame 6 is provided with hermetically-sealed construction; The sealing structure is the hermetically-sealed construction in the above-mentioned bottom side door of gondola car hermetically-sealed construction, specifically referring to the embodiment of above-mentioned bottom side door of gondola car hermetically-sealed construction, repeats no more here.
What should explain at last is: above each embodiment is only in order to the technical scheme of explanation the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to aforementioned each embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, perhaps to wherein part or all technical characteristic are equal to replacement; And these are revised or replacement, do not make the scope of each embodiment technical scheme of essence disengaging the utility model of relevant art scheme.
