Specific embodiment
The following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
Railway covered hopper car bi-layer tip cap as shown in Figure 1, including internal head cover 1, outer top cover 2 and switching mechanism 3, it is interior
Top cover 1 and the top open part of hopper wagon circular arc car body 6 are detachably connected, and outer top cover 2 passes through switching mechanism 3 and hopper wagon circular arc
The top open part of car body 6 is flexibly connected.
As shown in connection with fig. 4, internal head cover 1 includes framework 10, the cover board 12 being mounted on framework 10, is provided on cover board 12
Charging door 13 and be arranged on cover board 12 for lifting hanging ring 14.The front and rear sides edge of framework 10 is L in the present embodiment
Type beam 11, as shown in figure 5, L-type beam 11 includes widthwise edge 15 and vertical side 16, widthwise edge 15 uses lap joint form structure and funnel
Vehicle circular arc vehicle body side wall 5 is connected, i.e., widthwise edge 15 is shelved on the outwardly extending outer edge 18 in 5 top of hopper wagon circular arc vehicle body side wall
On, then widthwise edge 15 and outer edge 18 are fixed together by bolt；Meanwhile widthwise edge 15 and the outside of framework 10
Gasket 17 is lined between 18, and gasket 17 passes through 19 rivet or weld of rivet on the widthwise edge 15 of framework, such as Fig. 6 institute
Show, the sealing performance of internal head cover 1 when being installed and used with realizing；In addition, vertical side 16 and 5 inner wall of hopper wagon circular arc vehicle body side wall it
Between there are gap, convenient for the installation and dismounting of internal head cover 1, which is 5~10mm, preferably 7~8mm.
As shown in connection with fig. 2, switching mechanism 3 is fixedly connected with shaking in outer 2 end of top cover by riveting or bolt including one end
