Maintenance system of cable-stayed bridge solid pylon and application of maintenance system

Abstract

The invention provides a maintenance system of a cable-stayed bridge solid pylon and application of the maintenance system. The maintenance system comprises a climbing device, hanging point devices, a fall-protection device and operating platforms for personnel placement, the climbing device comprises a climbing ladder arranged on a pylon body, each hanging point device is fixed at the top end of the pylon and comprises a inserting rod, a rotating shaft, a hanging rope and a hanging hook, the hanging hook is positioned on the corresponding inserting rod, one end of each inserting rod is fixed at the top end of the pylon through the corresponding rotating shaft, the fall-protection device is fixed at the top end of the pylon, and the operating platforms are connected with the hanging hooks through the hanging ropes. The hanging point devices externally arranged at the top end of the pylon are small in size and small in influence on arrangement of other ancillary facilities at the top end of the pylon, so that maintenance workload is small; when not in use, the inserting rods of the hanging point devices can be rotated in the top end of the pylon, small influence can be caused on bridge landscape; when not in use, the operating platforms and the hanging ropes can be placed in a storeroom, thereby being avoided from being exposed outdoors; during maintenance, small influence can be caused on vehicle traveling due to small operating range.

Description

technical field [0001] The invention belongs to the field of bridge maintenance, in particular to a maintenance system for a solid cable tower of a cable-stayed bridge and its application. Background technique [0002] Cable-stayed bridges have been used more and more in bridge engineering. The anchor heads at both ends of the cable-stayed cables are respectively anchored on the cable tower and the main beam. The cable tower is the main load-bearing component, which bears the weight of the main beam and various loads transmitted by the cable-stayed cables. In order to eliminate potential safety hazards, the daily maintenance and inspection of the cable tower is also necessary. Because of the negligence in the inspection and maintenance, the anchor heads of the cable-stayed cables of some cable-stayed bridges are even corroded and broken, resulting in disasters. The "Design Rules for Highway Cable-Stayed Bridges" (JTG / TD65-01-2007) also clearly requires that the maintenance ...

Problems solved by technology

[0006] 2. The crane, as the main equipment for maintenance, has been placed in the environment of the tower top for a long time, exposed to the wind and the sun, causing great loss and short service life, and its parts are relatively large, making it difficult to replace the tower top;

[0007] 3. The cost of crane equipment is high
