Wall-climbing robot based on mooring helium balloon and using method

Abstract

The invention discloses a wall-climbing robot based on a mooring helium balloon and a using method thereof. The wall-climbing robot comprises a mechanical platform, a high-pressure fan, and detectionequipment. The upper end of the mechanical platform is connected with a helium balloon, the lower end of the mechanical platform is connected with a mooring part, and the mooring part can adjust the height position of the helium balloon; the helium balloon can drive the mechanical platform to move up and down in the vertical direction; the high-pressure fan is arranged on the side face of one sideof the mechanical platform, and the high-pressure fan can drive the mechanical platform to move left and right in the horizontal direction; and the detection equipment is installed on the side face of the other side of the mechanical platform, and the detection equipment can detect the defects of the building outer wall veneer. The wall-climbing robot has the advantages of low aerial work risk, wide application range, no detection blind area, convenience and flexibility in operation, high detection efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing of existing buildings, in particular to a wall-climbing robot based on a tethered helium balloon and a use method thereof. Background technique [0002] The exterior walls of existing high-rise buildings usually include finishing works, but due to various structural forms of buildings, complex construction techniques, chaotic construction management, uneven finishes or insulation materials, etc., the exterior walls of buildings have hollowing, cracking, falling off, etc. Quality problems, there are serious security risks. Therefore, it is urgent to develop a fast and effective non-destructive testing equipment and method to detect and evaluate the bonding quality and safety of exterior wall finishes. [0003] In order to improve the quality of building exterior wall decoration engineering, the Ministry of Construction has issued the "Construction Engineering Facing Brick Bonding S...

AI Technical Summary

Problems solved by technology

[0003] In order to improve the quality of building exterior wall decoration engineering, the Ministry of Construction has issued the "Construction Engineering Facing Brick Bonding Strength Inspection Standard" and "External Wall External Thermal Insulation Engineering Technical Regulations", but the method specified in the standard belongs to local damage detection. Scaffolding needs to be installed, the detection efficiency is low, the risk factor of the detection personnel is high, and it is impossible to carry out large-scale detection

Infrared thermography has certain applications in the detection of exterior wall defects, but in the detection of high-rise building exterior walls, due to site conditions, it is easy to cause the shooting elevation angle to be too large, which reduces the accuracy and reliability of identifying defects based on infrared images, resulting in local defects. There are problems such as misjudgment and missed judgment in defect identification

The problem in the detection of the exterior wall of high-rise buildings is that it is difficult for the detection equipment or personnel to touch the exterior wall. At the same time, it is affected by the complex detection environment of the exterior wall (factors such as the structure of the exterior wall, humidity and cleanliness). The traditional magnetic adsorption type, crawler type, Wall-climbing robots such as bionic adsorption type have the risk of falling from a high altitude, so they cannot be applied to the inspection of building exterior walls
