Description

TECHNICAL FIELD

[0002] The existing steel pipe concrete column compactness detection device is usually fixed with a ring on the outer wall of the steel pipe during detection, and a detection device is arranged on the ring for detection.

[0003] Since the height of the steel pipe is generally high, the detection position of the existing detection device is usually limited to a lower position, and the position of the higher position cannot be detected, so that the detection data is not accurate enough. In addition, in order to improve the overall structural strength, a hoop is usually arranged on the outer wall of the steel pipe. Therefore, even if the detection device is equipped with a moving assembly, it is difficult to cross the hoop to detect other positions. Therefore, a steel pipe concrete column compactness detection device (Chinese patent publication No. CN116660369B) is disclosed, which comprises a first mounting ring and a second mounting ring, and the first mounting ring and the second mounting ring are provided with a moving mechanism for driving the detection device to move.

[0004] The disclosed technology claims that the moving wheel and the hydraulic rod can cross the hoop, but its ability to cross the hoop still has significant deficiencies in actual application.

[0005] It is worth noting that the above-mentioned disclosed technology faces severe challenges in high-altitude areas. Low temperature environment can cause the viscosity of hydraulic oil to rise sharply, causing the hydraulic rod to respond slowly. Low air pressure conditions can reduce the friction between the moving wheel and the surface of the steel pipe, causing the moving wheel to slip. These factors together cause the detection efficiency and reliability of the existing detection technology to be greatly reduced in high-altitude areas. In order to adapt to the steel pipe concrete density test in high-altitude areas, it is necessary to further improve the above-mentioned disclosed technology. INVENTION CONTENTS
