Detailed description of the invention
As shown in Figure 2, ocean engineering steel rope water stop of the present invention, comprise a sidewall and arrange injecting hole and the cylindrical metal cover 14 adding sealing part, cylindrical metal overlaps 14 inner concentric and arranges Packed rubber bush 13; The sealing means sealing of rubber bush about 13 two ends is in the top and the bottom of described cylindrical metal cover 14.Cylindrical metal is overlapped 14 lower ends and is fixed on the deck 2 at steel rope crossing cabin place by lower butt flange 19 sealing means.
In figure, injecting hole is two, to make rubber bush 13 external cavity B inflate evenly when gas injection.And rubber bush 13 is for having elastomeric rubber coating, and there is waterproof characteristic.
In order to reach the hermetically-sealed construction that rubber bush 13 and cylindrical metal overlap 14, the invention provides a kind of optimal way, as shown in Figure 2, described rubber bush about 13 two ends turn up respectively and by upper butt flange 11 and lower butt flange 19 airtight be crimped on described cylindrical metal overlap 14 two end faces up and down on.Certainly, the connection mode that rubber bush 13 and cylindrical metal overlap between 14 is a lot, and as utilized annular compression ring mosaic mode, rubber bush 13 is crimped on cylindrical metal and overlaps on 14 barrels or end face, concrete mode, selects as required.In addition, in order to protect steel rope, upper butt flange 11 and lower butt flange 19 and described cylindrical metal overlaps 14 and are connected to end face and are positioned at flange hole inner edge place and offer circular groove, inlay and establish the soft sheath 12 of annular being encapsulated in butt flange 11 and lower butt flange 19 flange hole edge in circular groove.
Importantly, rubber bush 13 and cylindrical metal form a cavity B between overlapping 14, inject in this cavity B or release pressurized air, the expansion of rubber bush 13 can be controlled and reply virgin state, reach and realize clamping and unclamping to the steel rope worn in rubber bush 13.In the clamp state, because rubber inner surface soft under compressed air-driven is tightly attached on the surface of steel rope, the lubricating grease that steel rope surface is sticky simultaneously helps the micro gap sealing rubber face and steel rope wire element, under above-mentioned multiple factors effect, anti-sealing liquid can be completed pass through, namely achieve the watertight of steel rope by space.
