Description
Technical field
The present invention relates to a kind of encapsulating method and device of locomotive component, is a kind of locomotive top cap sealing method and device specifically, is mainly used in all kinds of electric locomotives.
Background technology
The sealing of locomotive is crucial for locomotive, badly will produce very big influence if seal, even cause electric short circuit the parts of locomotive, and accidents caused.Existing locomotive top cap sealing device mainly comprises the sealing (seeing accompanying drawing 1 to 3) between locomotive header and top cover, top cover and headwall and side wall and the top cover, existing sealing arrangement all is to force a metal edges to come the pinch-off seal bar to come leak free by a thread mechanism, and sealing band is in the very partial compression state of small area of contact.Because to sealing band is to be in the partial compression state, and the amount of compression of sealing band was fixed with the degree of tightness of top cover installation screw when top cover was installed, so not only sealing surface is little, and be easy to cause the overdraft of top seal bar, long-time use causes the sealing band permanent deformation easily, thereby reduces the sealing property of top cover, has shortened the service life of sealing band, and existing top seal device technique is comparatively complicated, makes inconvenient.Therefore necessary this is improved.
Summary of the invention
The objective of the invention is provides better locomotive top cap sealing method of a kind of sealing effectiveness and device in order to solve the deficiency of present locomotive top cap sealing device.With solve existing locomotive top cap sealing device technique complexity, sealing band easily produces permanent deformation and causes screen resilience to dwindle leakage phenomenons such as causing roof leaking.
The objective of the invention is to be achieved through the following technical solutions: the present invention adopts a kind of broadside leak free locomotive top cap sealing method, allow whole sealing band reduced overall seal, by the sealing band realization locomotive header of a broad and the sealing between locomotive header, locomotive header and locomotive headwall and locomotive headwall and the locomotive header.
According to the device that the inventive method provided be, a kind of broadside locomotive top cap sealing structure, these sealing pairs are mainly constituted by locomotive header, sealing pair sealing band, locomotive side wall, locomotive headwall and thread mechanism, wherein, between locomotive header and locomotive header, locomotive header and locomotive side wall and locomotive header and locomotive headwall, all be provided with the sealing pair sealing band, and all be by sealing pair sealing band leak free, and this kind hermetically-sealed construction is the broadside hermetically-sealed construction of sealing band reduced overall.The locomotive side wall of the sealing band of sealing arrangement and its coupling, top cover are installed much bigger than existing locomotive top cap sealing device of crossbeam and top cover area of contact.And sealing arrangement is to utilize the height of the member mounting guide rail that constitutes sealing pair itself and the diff-H of sealing band to come the bulk compressibility of sealing band has been carried out qualification, under the low temperature environment, the bulk compressibility of sealing band is no more than 50%, when using under normal temperature and the hot environment, the bulk compressibility of sealing band is no more than 30%.The sealing band of sealing arrangement is directly installed on the side structure and winds up in the mounting groove of beam and roof panel cross member, need not use viscose glue to make it to stick together with side wall and roof panel cross member.Sealing arrangement uses the HALFEN mounting rail and the HALFEN hold-down bolt that is complementary to come fastening top cover.The sealing strip material that constitutes this kind sealing arrangement is Ethylene Propylene Terpolymer (EPDM) rubber, and this kind leakproofing material has good rebound resilience, ageing-resistant, tear resistance, and its hardness can be runed operating mode according to locomotive and be selected.
The present invention has the following advantages:
1, this kind sealing arrangement seal area is big, can improve sealing effectiveness greatly.
2, this kind sealing arrangement limits the bulk compressibility of sealing band.Can avoid sealing band to produce overdraft, cause the sealing band permanent deformation after long-time.Help keeping the screen resilience of sealing band, improved reliability, the minimizing maintenance times of top seal, reduce top seal life cycle maintenance cost.
3, the sealing band of this kind sealing arrangement is directly installed in the mounting groove of side wall and roof panel cross member, need not use glue to make it to stick together with wind up beam and roof panel cross member of side wall, handle the even compression that helps sealing band when tighting a bolt like this, improve the sealing property of top cover.
4, this kind sealing arrangement uses the standard mounting rail, can be so that the installation of top cover and discharging.Compare with the traveling nut mount pad on the existing top seal device, this kind sealing dress is that mounting guide rail integral body is stressed, has increased bearing surface, rather than resembles local pressure the traveling nut, has reduced the stress concentration in mount pad zone.The force-bearing situation of mount pad can be effectively improved, mount pad generation endurance failure can be effectively avoided.
5, mounting guide rail, the hold-down bolt that constitutes this kind sealing arrangement is gauge member, buys the back back and draws materials according to installation site length, and production process is simple, can effectively reduce the production cost of manufacture.
