Problems solved by technology

However, after the construction of the cable-stayed bridge, the cable-stay / sling, one of its main stress-bearing components, begins to be exposed to the air for a long time, and the polyethylene (PE) protective layer on the surface of the cable-stayed bridge will show different degrees of hardening and aging, etc. Destruction phenomenon, accompanied by corrosion due to moisture and other acidic substances in the air, resulting in damage to the strength of the cables, thus endangering the safety of the bridge

Abstract

The invention discloses a stay cable / suspension cable surface spraying device which comprises an arc rotating platform fixed on a stay cable / suspension cable detection robot, a telescopic mechanism mounted on the arc rotating platform and a spraying module mounted on the telescopic mechanism, and the arc rotating platform can drive the telescopic mechanism to rotate around a stay cable / suspensioncable by 360 degrees; and the telescopic mechanism can enable the spraying module to get close to and away from the surface of the stay cable / suspension cable in the radial direction, the device can be carried by the stay cable / suspension cable detection robot to move to a certain height, and spraying treatment of the whole circle of the surface of the stay cable / suspension cable is completed. Thestay cable / suspension cable surface spraying device solves the problems that a PE protective layer on the surface of an existing stay cable / suspension cable is damaged, and protrusions cannot be removed.

Description

technical field [0001] The invention provides a cable-stay / sling surface spraying device, which is a device for spraying paint and glue for the corrosion of the PE protective layer on the cable-stay / sling surface on a cable-stayed bridge, and belongs to the field of robots. Background technique [0002] With the growth of economy and the rapid development of transportation, the development of long-span bridges is getting faster and faster. As a new type of modern bridge, cable-stayed bridges have been widely used in the world due to their wide adaptability and economy. Applications. Cable-stayed bridge cables are important stress-bearing components of cable-stayed bridges, and their safety performance has received widespread attention. However, after the construction of the cable-stayed bridge, the cable-stay / sling, one of its main stress-bearing components, begins to be exposed to the air for a long time, and the polyethylene (PE) protective layer on the surface of the cab...
