Description

Wear-resistant bridge inhaul cable

Technical Field

The utility model relates to the technical field of bridge inhaul cables, in particular to an anti-abrasion bridge inhaul cable.

Background

The fork lugs or lugs of the general suspension bridge, arch bridge slings and cable-stayed bridge guys are directly connected with the main cable clamps of the suspension bridge, arches of the arch bridge and towers of the cable-stayed bridge by adopting pin shafts. The connecting structure can realize the forward displacement of the bridge structure through the rotation of the pin shaft, and can overcome the secondary bending stress caused by the forward installation error in the construction process. However, due to the influence of wind and other loads in the actual running process of the bridge, small displacement in the transverse direction of the bridge structure can exist, and construction errors in the transverse direction of the bridge can also exist in the construction process. The factors can lead to larger bending stress of the inhaul cable in the use process, and even too large construction errors of the transverse bridge can lead to the inhaul cable not being installed in place. This situation seriously affects the safety, reliability and convenience of construction of the bridge cable.

In the connection structure of a cable for bridges disclosed in the authorized bulletin number CN201031355Y, the connection structure comprises a cable and a bridge structure reserved piece, one end of the cable is provided with a fork lug or an ear plate, the fork lug or the ear plate is correspondingly provided with an ear plate or a fork lug on the bridge structure reserved piece matched with the fork lug or the ear plate, and the fork lug or the ear plate of the cable is in pin joint with the ear plate or the fork lug of the bridge through a pin shaft, and the connection structure is characterized in that: and a joint bearing is embedded in the pin hole of the ear plate of the inhaul cable or the bridge. After the connection mode is adopted, the fork lugs or the lug plates of the inhaul cable can realize the rotation along the bridge direction through the pin shafts, and can realize the inclination of the transverse bridge direction in a certain range through the joint bearing. The inhaul cable adopting the connecting method is well suitable for the displacement of the bridge structure in the forward direction and the transverse direction, overcomes the secondary bending stress of the inhaul cable caused by construction errors, and provides guarantee for the use safety, the reliability and the construction convenience of the bridge inhaul cable; however, if the joint shaft is rusted, the joint shaft cannot be rotationally adjusted when the joint shaft is slightly deviated due to the influence of wind and other loads in the actual running process of the bridge.

Therefore, we propose an anti-abrasion bridge cable to solve the above problems.
