Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices, in particular to a flying robot device for monitoring inclined cables. Background Art

[0002] Cable-stayed bridges, as a key structural form of modern long-span bridges, have demonstrated their unique technical advantages, especially when crossing deep canyons, bays, and large rivers. This type of bridge, also known as a cable-stayed bridge or cable-stayed suspension bridge, is a type of bridge that has emerged in recent decades. Its uniqueness lies in the use of cables to closely connect the main beam and the bridge tower to form a stable force system, which is not only economical and efficient, but also has excellent earthquake resistance.

[0003] The core of a cable-stayed bridge is the cable, which carries all the loads transmitted from the bridge deck and transmits them to the ground through the bridge tower. Therefore, daily inspection and maintenance of the cable is crucial. However, with the increase in the span of the cable-stayed bridge, the area of ​​the cable exposed to the natural environment also increases accordingly, and the impact of wind vibration and rain vibration becomes increasingly significant. In order to cope with this problem, designs such as spiral cables and indented pit cables are widely used in new bridges, but this also brings new challenges. Long-term exposure to wind, sun and rain will cause the polyethylene sheath on the surface of the cable to harden and crack, and in severe cases, it may even cause the steel wire bundle to rust and break.

[0004] At present, the inspection of cable-stayed bridge cables is mainly focused on appearance and cable force measurement, but manual inspection is still mainly used, which is inefficient and has safety hazards. For example, a winch is used to drag a hanging basket trolley carrying inspectors for measurement. This method is not only dangerous, but may also cause secondary damage to the cable. Therefore, the introduction of industrial robots for cable inspection has become an industry trend.

[0005] A variety of cable inspection robots have been developed at home and abroad, including wheeled, pneumatic and hydraulic creeping, and snake-like climbing types. Among them, wheeled robots have been widely used due to their simple structure, fast climbing speed, and strong load-bearing capacity. However, they also face challenges such as large size, heavy weight, and reliance on cable power supply, which to some extent limit their operational flexibility.

[0006] In addition, existing inspection robots may accidentally squeeze or aggravate the damage of the sheath during actual operation. For spiral cables, due to the unique spiral protrusion structure on their surface, existing inspection robots often find it difficult to achieve effective inspection without damaging the cable, which further increases the difficulty of inspection.

[0007] In addition, when performing tasks, especially in complex environments, the robot may encounter various obstacles, such as trees, buildings or other moving objects. Collisions between the robot and these obstacles may cause serious harm or damage, and may even cause the robot to fail or be destroyed. Utility Model Content
