Prestress flexible sealing device of inhaul cable anchoring system
The invention discloses a prestress flexible sealing device of an inhaul cable anchoring system, and particularly relates to the technical field of bridge building facilities. Comprising a sleeve, a sealing ring is connected between the sleeve and a cable body, a heat conduction wire is embedded in the semicircular sealing ring, a first sliding groove is formed in the sleeve, the semicircular sealing ring is slidably connected to the first sliding groove, a first spring is connected between the semicircular sealing ring and the first sliding groove, and an area defined by the sleeve and the sealing ring forms a sealing cavity; inert gas is injected into the sealing cavity, and a pressure sensor is arranged in the sealing cavity of the semicircular sealing ring. A hydraulic box is wrapped outside the sleeve and filled with hydraulic oil, a push rod is arranged on the hydraulic box, a second sliding groove is formed in the cable body, the push rod is connected into the second sliding groove in a sliding mode, and a second spring is connected between the push rod and the side wall of the second sliding groove. By the adoption of the technical scheme, the problems that an existing sealing device of the inhaul cable anchor head is prone to water seepage corrosion, and the safety and durability of the sealing device are reduced are solved, and the service life of the inhaul cable anchor head can be prolonged.
本发明专利公开了拉索锚固系统预应力柔性密封装置，具体涉及桥梁建筑设施的技术领域。包括套筒，套筒与索体之间连接有密封环，半圆形密封环环内嵌设有导热丝，套筒内开有第一滑槽，第一滑槽滑动连接有半圆形密封环，半圆形密封环与第一滑槽之间连接有第一弹簧，套筒和密封环围合的区域形成密封腔，密封腔内注入有惰性气体，半圆形密封环密封腔设有压力传感器。套筒外包覆有液压箱，液压箱内充满有液压油，液压箱上设有推杆，索体上设有第二滑槽，推杆滑动连接在第二滑槽内，推杆与第二滑槽侧壁之间连接有第二弹簧。采用本发明技术方案解决了现有的拉索锚头的密封装置易出现渗水腐蚀而降低其安全性、耐久性的问题，可用于提高拉索锚头的使用寿命。
