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.

Embodiment approach

[0035]When the present invention is used, the landing platform 5 is trailed to the drone to the drone to the unmanned vehicle by the traction rope 11, and then the brake device 8 at the bottom of the base 6 is locked, so that the landing platform is fixed, and then regulate the lifting frame. 9. Keep the drop plate 10 level, then the remote control drone landed on the vertical plate 10 at the top of the landing table 5, the contact plate 3 with the grille hole 4 is in contact with the landing plate 10, and can improve the off-plane land. Stability, the beam 1 is supported by the leg 2 to support the drone of the drone more stable.

Embodiment

[0037]A bridge detects a drum-up stand, including a beam 1 mounted on the bottom of the drone, and the beam 1 is provided, two of the beams 1 in parallel at the bottom of the drone, the beam and no Human-machine screw connection, two of the beams 1 is provided with leg 2, and the leg 2 is inclined to the outer direction of the drone, and the leg 2 includes an upper leg portion 14 and a lower leg portion 15, the upper The top of the leg portion 14 is integrally formed with the crossbar 1, the lower leg portion 15 bottom screw connecting the contact plate 3, the contact plate 3 is provided with an arc plate 12, and the arc plate 12 extends upward from the horizontal direction. A plurality of ridges 13 are integrally formed on the bottom surface of the arc plate 12, and the plurality of the ridges 13 are perpendicular to the contact plate 3 edge. A plurality of grille holes 4 are disposed on the contact plate 3, and the plurality of the grille bore 4 is linearly distributed over the co...

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...
