Railway tunnel lining quality nondestructive detection boom and detection method thereof

Abstract

The invention discloses a railway tunnel lining quality nondestructive detection boom and a detection method thereof. A radar antenna is mounted on a radar antenna clamping rack; a floating buffer oil cylinder mechanism is connected with the radar antenna clamping rack; the floating buffer oil cylinder mechanism, a three-joint arm, a two-joint arm and a basic arm are connected in sequence; a pitching arm is hinged to the basic arm; a pitching derricking cylinder is connected between the pitching arm and the basic arm; the pitching arm is hinged to a rotary base; a lower pitching derricking cylinder is mounted between the pitching arm and the rotary base; a rotation driving device is disposed on the rotary base; a mounting seat is disposed at the bottom of the rotary base; the rotary base is connected to a traveling carrier. According to the railway tunnel lining quality nondestructive detection boom and the detection method thereof, a multistage-pitching multistage-retractable structure is adopted and waist rotation can be achieved, so that attachment of the radar antenna to the wall surface of a tunnel lining is achieved, the labor intensity of detectors is relieved, the detection quality and working efficiency are improved, nondestructive detection for single-track or double-track tunnels can be achieved, and the railway tunnel lining quality nondestructive detection boom and the detection method thereof can adapt to certain uneven road surfaces. By means of the railway tunnel lining quality nondestructive detection boom and the detection method thereof, the traveling mileage can be recorded, the postures of the boom can be automatically adjusted, the side track height is maintained within a certain range, and the characteristic of high measuring accuracy is achieved.

Description

technical field [0001] The invention relates to railway tunnel lining quality testing equipment and a method thereof, in particular to a railway tunnel lining quality non-destructive testing jib and a testing method thereof. Background technique [0002] With the continuous development of national transportation, the number of railway tunnels is increasing year by year, and tunnel defects are gradually appearing in construction and operation. Therefore, there is a need for a comprehensive and rapid non-destructive testing equipment for tunnel lining quality, so that tunnel construction defects and operational diseases can be treated in advance. The existing detection equipment mainly has the following defects: [0003] ① When the antenna is lifted manually, 2 to 3 people are required to support the antenna on the working platform, which is prone to safety accidents, and due to factors such as physical strength, the antenna often cannot ensure that it is closely attached to ...

AI Technical Summary

Problems solved by technology

[0003] ① When the antenna is lifted manually, 2 to 3 people are required to support the antenna on the working platform, which is prone to safety accidents, and due to factors such as physical strength, the antenna often cannot ensure that it is closely attached to the lining surface, and the positioning of the measuring line is not accurate, which directly affects The quality of data collection to some sections of the survey line leads to misjudgments and missed judgments of some lining defects

[0004] ② When manually collecting mileage, due to the complex tunnel environment, testers often mistakenly mark mileage marks, resulting in incorrect mileage positioning; when the antenna moves at an uneven speed and moves forward in a serpentine shape, it is easy to cause inaccurate mileage estimation between every two mileage marks

In this way, the determined location of lining quality defects is inaccurate or even wrong

[0005] ③Individual tunnel lining system detection vehicle arm frame system is bulky, complex hydraulic system, complex control adjustment, heavy vehicle body, high cost of use, which is not conducive to popularization

[0006] ④ For new tunnels, due to the uneven road surface, the antenna may be detached from the lining surface and cannot be mechanically compensated

[0007] ⑤It does not have the ability to rotate the boom or the platform, and it is difficult to adjust during the detection process, and it is easy for the antenna to detach from the wall
