Unmanned aerial vehicle for measuring coating film thickness of high-rise steel structure

Abstract

The invention discloses an unmanned aerial vehicle for measuring the coating film thickness of a high-rise steel structure. The unmanned aerial vehicle comprises a flight mechanism, a film measuring mechanism and an adsorption and separation mechanism; the flight mechanism comprises a fuselage connected with a plurality of horizontal rotor wings; the film measuring mechanism comprises an equipmentplate assembled on the fuselage through a rotary shaft, the equipment plate has the rotational degree of freedom at least within the straight angle range around the axis of the rotary shaft, and a film measuring probe is fixed to the equipment plate; and the film measuring mechanism and the adsorption and separation mechanism are both arranged on the same surface of the equipment plate, the adsorption and separation mechanism comprises a vertical rod and a jacking mechanism which are vertically fixed to the equipment plate, a permanent magnet is arranged at the top end of the vertical rod, the jacking mechanism has the linear reciprocating degree of freedom in the direction parallel to the vertical rod, and the vertical distance between the permanent magnet and the equipment plate is within the vertical distance between the top end of the jacking mechanism and the equipment plate when the top end of the jacking mechanism is located at the two limit positions. By adopting the unmannedaerial vehicle, paint film detection can be conducted on the steel structure at the high position which is inaccessible to people, the upper surface, the lateral facades and the lower surface of the steel structure all can be detected, and thus the unmanned aerial vehicle is widely applied.

Description

technical field [0001] The invention relates to the field of paint film thickness measuring equipment, in particular to an unmanned aerial vehicle used for measuring the film thickness of a high-rise steel structure coating. Background technique [0002] After the steel structure is brushed with a coating, the coating will gradually become thinner due to aging, pulverization and other reasons and will gradually fail. If the coating is too thin, the steel structure will be corroded and damaged. At the same time, the quality of some coatings was unqualified during the coating construction. After the construction was completed, the owner proposed to re-inspect, so the coating film thickness inspection should be carried out on the steel structure. However, it is difficult to detect the film thickness of high-rise steel structures, it is difficult for personnel to reach, and the detection cost is high. Contents of the invention [0003] The problem to be solved by the present ...
