The specific embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast the description of drawings specific embodiment of the present utility model.
As Fig. 1, Fig. 2, shown in Figure 3, present embodiment provides a kind of railway locomotive top seal device, described sealing arrangement includes locomotive car body 1 and locomotive header 2, described locomotive car body 1 have with described top cover 2 around cooresponding top beam of laterally 11 and head piece 12, in the present embodiment, described top beam of laterally 11 is arranged on the top of the car body left and right sides, and described head piece 12 is arranged on the top of both sides, car body front and back.Be provided with between described top cover 2 and the car body 1 and captive joint both latching device 3; Described sealing arrangement also include be located on around the described top cover 2 and with locomotive car body top beam of laterally 11 and head piece 12 cooresponding sealing bands 4, described sealing band 4 is integral ring-shaped structure (shown in Fig. 5 A).
In the present embodiment, shown in Fig. 2, Fig. 3 and Fig. 4 A, be provided with seal groove 5 with described top beam of laterally 11 and head piece 12 cooresponding positions on described locomotive header 2, as shown in the figure, sealing groove 5 is fixedly connected on the described top cover 2 by connecting element.Described sealing band 4 is arranged in the described seal groove 5, and shown in Fig. 4 B, described seal groove 5 inner both sides form draw-in groove 51.
Shown in Fig. 5 A, Fig. 5 B and Fig. 5 C, in the present embodiment, the cross-sectional plane of described sealing band 4 is hollow book wall construction, and described sealing band 4 is provided with the clamping part 41 that can corresponding be fastened in the described draw-in groove 51.Described sealing band 4 is respectively equipped with the through hole 42 (shown in Fig. 5 B, Fig. 5 C) of its book wall of perforation in each the corner both sides that is positioned at integral ring-shaped structure; This through hole 42 is arranged on the medial margin of annular sealing strip 4.
Shown in Fig. 3, Fig. 5 A and Fig. 5 C, in the present embodiment, described sealing band 4 is with respect to the position of described head piece 12, and is provided with retaining section 43 along sealing band 4 lateral borders.As shown in the figure, because the head piece 12 of locomotive car body is a groove shapes, may have ponding in this groove, enter in the hermetically-sealed construction in order to prevent ponding, therefore, the relevant position is provided with this retaining section 43 on sealing band 4, to play the dash effect.
From the above mentioned, during top seal, be around being mounted in the top seal groove 5 with sealing band 4, clamping part on the sealing band 4 41 is fastened in the respective card slot 51 of seal groove 5, by latching device 3 top cover 2 and car body 1 are tightly locked again, so that top cover 2 reclines and puts in place with top beam of laterally 11, horizontal curb girder 12, because sealing band 4 is provided with described through hole 42, after sealing band 4 is compressed, air in the space of hollow can be extruded from described through hole 42, makes sealing band 4 can reach better sealing effectiveness.In the present embodiment, described latching device 3 can adopt bolted connection (as shown in Figure 2).Further, in the present embodiment,, make the presentation quality of described sealing band 4 good, and sealing band do not have the slit, improved the sealing effectiveness between car body and the top cover, increased the safety of locomotive driving because described sealing band 4 adopts integral ring-shaped structure; Moreover, because described sealing band 4 is integral ring-shaped structures, can avoid using the powerful fast Si Jiaochu that does bonding glue adhering and sealing bar when mounted, therefore, can simplify technological process, reduce the technology cost, enhance productivity.
Further, in the present embodiment, described sealing band 4 is that (that is: the position at four angles) whole butt joint manufacturing forms the employing particular manufacturing craft in the end with four edges.The forming method of described sealing band is:
Two limits of sealing band that performed are injected earlier in the butt joint particular manufacturing craft by the drawing dimensional characteristic, then in the sealing band raw MAT'L with butt joint corner pours into the cavity of butt joint mould, it is one with injecting two limits appearances of sealing band of dock in the mould earlier that energising heating makes it to melt the back, treats just to have finished after mold cools down is dismantled the butt joint at an angle.All the other each angles and the like, shared quadruplet mould is finished in the forming process.
This integral sealing bar in the present embodiment is through leak test repeatedly, and affirmation can meet design requirement.Use by reality, railway locomotive top seal device of the present utility model, because the sealing band profile is integral ring-shaped structure, and cross-sectional plane is hollow, thin-wall construction, its surface quality, interior tissue, performance figure are all higher, and the widespread use sealing effectiveness is fine on the locomotive at home.
