Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of anchorage protection covers, and in particular relates to a bridge cable anchorage protection cover. Background Art
[0002] As the "lifeline" of a cable-stayed bridge, the cable-stayed cable is an important component of the bridge and serves as a link between the tower and the main beam. The cable-stayed cable is mainly composed of steel wires, anchors and protection systems. Its quality and service life directly determine the structural safety of the cable-stayed bridge. After the failure of the protective structure, water or other corrosive media infiltrates into the cable duct or the cable body, corroding the anchor structure and steel wires, which is one of the main causes of cable-stayed cable failure. On the joint end surface of the conventional cable-stayed cable anchor ring and the anchor pad, several drainage troughs are provided. If the cable duct seal fails during construction or operation, the water that enters the cable duct will be discharged through the drainage troughs. In order to avoid erosion of the cable-stayed cable anchor structure, after the bridge cable is installed, an anchor protection cover is usually installed and combined with cable duct sealing and anti-corrosion measures to prevent moisture and other pollutants from entering and corroding the anchor structure.
[0003] Conventional anchorage covers are large and provide protection along with the anchor ring. They are bolted to the anchor pad outside the anchor ring. If the cable guide seal fails during operation and water enters, the accumulated water will drain through the sluice and accumulate in the conventional anchorage cover. If this water is not drained promptly, it will negatively impact the anchorage structure and make post-installation inspection and maintenance difficult. Furthermore, some bridges cannot be fitted with conventional anchorage covers fixed to the anchor pad due to the small size of the anchor pad and the limited installation space. Therefore, a bridge cable anchorage cover has been proposed. Summary of the Invention
[0004] In view of the deficiencies in the prior art, the present invention provides a bridge cable anchor protection cover to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a bridge cable anchorage protective cover, comprising:
[0006] A first cover body, wherein first flanges are provided at both upper and lower ends of the exterior of the first cover body, a cover plate is provided on one side of the upper end of the first cover body, and the cover plate is made of transparent material, a second cover body is provided at the lower end of the first cover body, a second flange is provided on one side of the lower end of the second cover body, and the second flange is fixedly connected to the second cover body, sealing members are provided between the cover plate and the first flange and between the first cover body and the second cover body, and the cover plate and the first cover body and the first cover body and the second cover body are fixed by bolts.
[0007] Furthermore, a plurality of ribs evenly distributed along a ring shape are provided on one side of the upper end of the second flange, and the ribs are fixedly connected to the second flange and the second cover body, so that the ribs improve the stability between the second flange and the second cover body.
[0008] Furthermore, an outer ring is provided on one side of the upper end of the cover plate, and the outer ring is fixedly connected to the cover plate.
[0009] Furthermore, an inner ring is provided inside the outer ring, and the inner ring is rotatably connected to the outer ring, and the inner ring rotates inside the outer ring.

[0012] This utility model provides an anchor protection cover on the outer end of the anchor ring to address the problem of water accumulating in conventional protective covers after draining through the drain trough following cable conduit seal failure during construction and operation, effectively protecting the exposed portion of the anchor. The segmented, combined structural design addresses the issue of limited installation space and the inability to install the entire structure. The transparent cover eliminates the problem of conventional protective covers obscuring the interior, facilitating inspection. BRIEF DESCRIPTION OF THE DRAWINGS
