Full-life sling capable of being monitored and maintained

Abstract

The invention relates to a full-life sling capable of being monitored and maintained, and belongs to the technical field of sling maintenance. The full-life sling comprises a sling body, a sling sheath, a connecting cylinder and a lower end anchor cup. The sling sheath is arranged on the sling body above the connecting cylinder in a sleeving mode, the sling body wrapped with the sling sheath is partially peeled off to expose steel wire bundles, a gap between the sling wire bundles is used as a dry air circulation gap D1, the steel wire bundles at the lower end of the sling body are scattered in a tapered shape and anchored in the lower end anchor cup to form a tapered casting body, a gap between the tapered casting body and the inner wall of the lower end anchor cup is used as a dry air circulation gap D2, and the dry air circulation gap D1 and the dry air circulation gap D2 communicate with each other in an up and down mode; and a viewport is formed in the sling sheath, the sling sheath is further provided with a dry air inlet, the dry air inlet directly communicates with the dry air circulation gap D1, a dry air outlet is formed in the outer wall of the lower end anchor cup, andthe dry air outlet communicates with the dry air circulation gap D2. The full-life sling makes targeted dry air maintenance, cures the sling disease, and restores a normal state of the sling.

Description

technical field [0001] The invention relates to a monitorable and maintainable full-life sling, which belongs to the technical field of sling maintenance. Background technique [0002] Judging from the existing defects of the suspension bridges that have been built so far, the most serious damage to the suspensions occurs at the lower anchorage, and the existing detection methods cannot effectively detect this part. Once abnormalities are found in the later operation, After a comprehensive inspection of the sling, the sling has been severely corroded and needs to be scrapped and replaced. If it cannot be found in time, severe cases will cause broken cables, which will bring huge safety hazards to the operation of the bridge. At present, there is no means to prevent and detect the disease at the lower end of the sling. Although the existing method can pass dry air from one end of the sling to the other to achieve the purpose of prolonging the life of the cable body, this te...

AI Technical Summary

Problems solved by technology

Although the existing method can pass dry air from one end of the sling to the other to achieve the purpose of prolonging the life of the cable body, this technology cannot accurately know the internal state of the specific sling, which has high energy consumption, is not environmentally friendly, and the actual effect is not good. In addition, it is impossible to intuitively know the corrosion of the steel wire in the sling
