A bridge detection drone landing gear

Abstract

The invention provides a bridge detection UAV landing gear, which mainly relates to the field of UAVs. An unmanned aerial vehicle landing gear for bridge detection, including a beam installed at the bottom of the drone, legs are provided at the bottom of the beam, a contact plate is provided at the bottom of the legs, a plurality of grid holes are provided on the contact plate, a The landing gear of the bridge detection UAV also includes a landing platform adapted to the contact plate, the landing platform includes a base, a wheel set is arranged at the bottom of the base, a braking device is arranged on the wheel set, and a lifting device is arranged on the top of the base. frame, the top of the lifting frame is provided with a lifting plate, and the front end of the base is provided with a traction rope. The beneficial effect of the present invention is that: the present invention can play a buffering effect on the landing of the UAV, reduce the difficulty of taking off and landing of the UAV, reduce the probability of damage to the UAV, and enable the UAV to successfully complete the bridge detection operate.

Description

Technical field[0001]The present invention mainly involves the field of drone, in particular a bridge detection drone upright landing gear.Background technique[0002]As a path of the road, it is the extension of the road to build the road on the special terrain. The bridge is divided according to the feature characteristics, there is a basic type of beam bridge, arch bridge, just bridge, suspension bridge, combination system bridge (cable-stayed bridge). Different bridges have different types of force, during the use of the bridge, it is often maintained to repair the bridge. For the maintenance of the surface of the bridge, it is now multi-use drone to assist the bridge whether there is a naked eye showing cracks, for longer Bridge (via bridge, cross-sea bridge, etc.), requires segmented using drones to monitor bridge monitoring, which requires repeated lifting and landing of drones, and drone housings are generally lighter. Early tip accidents during the process of the machine:[000...

AI Technical Summary

Problems solved by technology

[0002] As a kind of road, a bridge is an extension of a road built on a special terrain. Bridges are divided into five basic types according to their stress characteristics: beam bridges, arch bridges, rigid frame bridges, suspension bridges, and composite system bridges (cable-stayed bridges). , Different bridges have different stress types. During the use of the bridge, the bridge needs to be overhauled from time to time. For the overhaul of the bridge surface, drones are now used to assist in monitoring whether there are visible cracks in the bridge body. For longer Bridges (viaducts, sea-crossing bridges, etc.) need to use UAVs for bridge monitoring in sections, which requires repeated take-off and landing of UAVs. Overturning accidents are extremely prone to occur during the take-off and landing of the aircraft:

[0003] The operation process of UAV take-off and landing is quite difficult. The speed of the UAV is too high, which will cause the UAV to fall and be damaged. Some bridge sections are inclined surfaces, and the UAV cannot complete the landing. Forced landing will also cause unmanned If the drone falls, it will seriously affect the re-take-off of the drone and delay the inspection progress of the bridge.
