Problems solved by technology

[0005] 2. It is difficult to achieve sealing at the transition between the cone and the cylinder of the device. When the cable body and the cable guide are eccentric, the vibration of the cable will easily cause cracks or seal failure here, and the applicability is poor;
[0006] 3. Due to the different bridge structures, there are many combinations of cable bodies and cable guides, and waterproof covers of various specifications are required, resulting in many types of molds and high production and management costs.

Abstract

A flexible waterproof device for a bridge cable comprises a cover body, a beam clamp and a pressing ring. The cover body is an integral type rubber waterproof cover body with one opening in one side, and the outline of the cover body is a conical shape with the upper portion being a small circle, the lower portion being a large circle and the middle portion being a circular arc for transition after splicing; a convex edge is arranged on a splicing seam with one opening in one side, and a plurality of convex ribs are arranged on inner cavities of a large circle section and a small circle section of the cover body; and the pressing ring adopts a two-sectional type and spliced into a ring shape through connection of bolts, a plurality of grooves I are formed in the outer circle of the pressing ring, a plurality of grooves II are formed in an inner cavity of the compressing ring, the pressing ring is buckled on a cable body under an assembly state, the small circle end and the large circle end of the rubber waterproof cover body are circumferentially folded around the pressing ring and a cable guiding pipe correspondingly, the convex ribs II of the inner cavity of the small circle end section of the rubber waterproof cover body are tightly attached to the grooves I of the outer circle of the pressing ring in a corresponding mode, and a beam clamp body I and a beam clamp body II are installed on the outer sides of the small circle end section and the large circle end section of the rubber waterproof cover body correspondingly. According to the flexible waterproof device for the bridge cable, sealing failure caused due to inhaul cable vibration influence is avoided, the sealing effect is more reliable and durable, and production cost and later maintenance cost are low.

Description

technical field [0001] The invention relates to a waterproof sealing cover suitable for a stay cable body and a method for realizing the waterproof sealing of the cable body waterproof cover. Background technique [0002] The waterproof device is an indispensable and important sealing part of the cable. At present, most of them are steel waterproof covers made of stainless steel roll-welded or two-piece cast iron; this type of waterproof cover is likely to cause its seal to fail when the cable vibrates; secondly, the production The maintenance cost is relatively high; moreover, the applicability is poor, and different cable guides cannot be applied; when the cable body and the cable guide are eccentric, it is difficult to install. [0003] The utility model patent whose patent announcement number is CN201660849U discloses a bridge cable rubber waterproof device. Although it can partially solve the above problems, it still has the following deficiencies: [0004] 1. The conn...
