Embodiment 1

[0018] Example 1, such as Figure 1 to Figure 3 As shown, this technical solution is a detection device for a bridge pier surface by a wired drone, including a rotor drone 1, a contact rod 2 and a lifting mechanism 4, and the lifting mechanism 4 also includes a frequency conversion motor 5, a transmission shaft 6 and the frame 8, wherein the frequency conversion motor 5 is fixedly installed on the frame 8, the output end of the frequency conversion motor 5 is fixedly connected with the transmission shaft 6, and the transmission shaft 6 is fixed with a reel I9 and a reel II10 in sequence along the axial direction, so Both the reel I9 and the reel II10 are wound with twisted ropes 11, and the contact rods connected to the positive and negative input terminals of the rotor drone 1 can be connected to the positive and negative output terminals of the external power supply. The mechanism 4 consists of two parts. The twisted ropes on the drums of each lifting mechanism are respectiv...

Embodiment 2

[0020] Example 2, such as Figure 1 to Figure 3 As shown, on the basis of Example 1, the twisted rope 11 wound on the reel is optimized, and the ends of the twisted rope 11 are hung with counterweights 12 to maintain the contact rod connected by the twisted rope. The stability of the drone ensures that the swing of the rotor drone positioned on the contact rod is small, and the accuracy of cruise shooting is improved.

Embodiment 3

[0021] Example 3, such as Figure 1 to Figure 3 As shown, on the basis of Embodiment 1, the setting position of the lifting mechanism 4 is optimally designed, and the two lifting mechanisms are symmetrically arranged left and right to keep the contact rod 2 connected by the twisted rope 11 in a horizontal position and ensure that there is no one on the rotor. The horizontal shooting detection of the bridge pier surface by the machine.

Abstract

The invention discloses a wired unmanned aerial vehicle pier surface detection device which comprises a rotor unmanned aerial vehicle, touching rods, a power supply and a lifting mechanism. The lifting mechanism further comprises a variable-frequency motor, a transmission shaft, reels and a rack. The variable-frequency motor is fixedly mounted on the rack. The output end of the variable-frequency motor is fixedly connected with the transmission shaft. The first reel and the second reel are sequentially fixed to the transmission shaft in the axial direction. The touching rods connected with the rotor unmanned aerial vehicle are separately connected with the output ends of an anode and a cathode of the power supply. Twisted ropes on the lifting mechanism reels are separately connected with the same ends of the touching rods. By controlling rising and falling of horizontally operated rotor unmanned aerial vehicle observation equipment through the lifting mechanism in the longitudinal direction, the rotor unmanned aerial vehicle can achieve horizontal cruise, shooting and observation in the axial direction of the touching rods, and a technical blank of large bridge detection is filled.

Description

technical field [0001] The invention relates to the technical field of bridge detection, in particular to a detection device for a bridge pier surface using a wired drone. Background technique [0002] At present, the inspection of bridges in China, especially in large-scale bridges with structures such as high-speed rail bridges, highway bridges, cable-stayed cables, suspension cables, and suspenders, is mainly performed externally by manual or inspection vehicles. Due to the geographical shape and the structure of the bridge itself , it is still impossible to conduct a comprehensive close-up observation of the piers of such large bridges. Rotor UAV (hereinafter referred to as UAV) is widely used in various industries because of its stable flight, simple and convenient operation, low price, and easy installation of various functional equipment. It can be used to photograph and detect bridge piers, but Usually, bridge piers have four sides, and the area of ​​only one side i...
