Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, a kind of high damping type flexible suspension peculiar to vessel of the utility model is installed on ship ventilation pipe
In the system of road, pipe-line system is by taking rectangular air duct as an example.Often set flexible suspension includes spring hanger, clip 18, angle steel 16, cushion block
17, ventilation shaft is fixed by clip 18, and the both sides of clip 18 pass through locking screw by the lower connecting spring suspension bracket of bolt 10, spring hanger
Female 1 angle cleat 16, angle steel 16 is welded with deck in ship structure.
Spring hanger include locking nut 1, top nut 2, packing ring 3, rubber spring seat 4, rubber sleeve 5, spring 6, pressing plate 7,
Upper bolt 8, lower cover 9, lower bolt 10, plain washer 11, spring washer 12, lower nut 13, upper cover plate 14, shell 15；Lower cover 9
Welded with the one end of shell 15, central aperture is provided with lower cover 9, lower bolt 10 passes through the central aperture of lower cover 9, and with putting down
Packing ring 11, spring washer 12, lower nut 13 are fixed；Upper cover plate 14 is arranged to be provided with the other end of shell 15, upper cover plate 14
