Description

Technical Field

[0001] This utility model relates to the field of coal mine safety detection technology, and in particular to a reciprocating device for detecting defects in well shafts. Background Technology

[0002] Intelligent inspection equipment has begun to be used in the field of coal mine safety monitoring in China. These devices are very suitable for shaft inspection work due to their simple operation, high efficiency and strong adaptability.

[0003] However, existing detection equipment, such as ordinary cameras, infrared cameras and cross-section scanners, has limited detection accuracy and is difficult to accurately identify key issues such as well casing deformation, well wall spalling and surface cracks.

[0004] Ground penetrating radar, as a highly efficient detection tool, has significant advantages in well casing inspection, and can clearly reveal potential defects in the well casing;

[0005] However, in the environment of ultra-deep vertical shafts, the performance of air-coupled ground-penetrating radar may be affected by interference from ladder rooms and pipelines, which may lead to reduced image quality and thus affect the accurate assessment of the wall condition.

[0006] Therefore, in order to ensure the accuracy of inspection results, intelligent inspection equipment needs to conduct close-range detailed detection and comprehensive inspection of areas with unclear images to ensure that accurate and effective inspection data can be provided.

The purpose of this utility model is to use an electric push rod to drive the slide, which carries two sets of side blocks, to move along the arc panel. This causes the two sets of connecting rods to rotate relative to each other while moving, thereby pushing out the arc-shaped block. The arc-shaped block carries the ground-penetrating radar outward, realizing a close-range detection mode to solve the above problems. This utility model achieves the above objective through the following technical solution:

[0038] like Figure 7 As shown, the first link 23 has a movable shaft 231 at one end and a side shaft 233 at the other end, and an intermediate shaft 232 at the center of the first link 23.

[0044] The basic principle of this utility model:

[0045] like Figure 1 As shown, when the detection device receives the detection command, it pulls up the steel wire rope 13 to release the line, and then moves the disc 10 down along the positioning steel wire rope 14 through the steel wire rope hole 101 via the central square 12 to perform detection. At this time, the arc plate 20 is retracted into the side groove 11. The fixed ground penetrating radar 102 and the movable ground penetrating radar 22 work together to perform circular line detection. At the same time, the three-dimensional laser scanner 31, CCD camera 33 and light source 34 work synchronously to perform three-dimensional scanning and image acquisition program detection.

[0046] like Figure 2 As shown, when an unidentified defect is detected, the electric pusher 16 pushes the rod 161, which in turn pushes the slide 27 to move. This causes the slide 27 to move the slide rod 252 and the slide rod 262, which in turn causes the first side block 25 and the second side block 26 to move outward along the arc panel 112 and the arc panel 213, respectively. This causes the first connecting rod 23 and the second connecting rod 24 to rotate in opposite directions about the intermediate shaft 232, which narrows the angle between the first connecting rod 23 and the second connecting rod 24. This causes the movable shaft 1 231 and the movable shaft 241 to slide in the arc groove 211, thereby pushing out the arc plate 20. The arc plate 20 carries the movable ground penetrating radar 22 outward, allowing the movable ground penetrating radar 22 to perform closer-range detection.

[0047] After the close-range detection is completed, the detection device responds as follows: Figure 1 As shown in the diagram, the steel wire rope 13 is then pulled up to continue releasing the line, causing the disc 10 to probe downwards.

[0048] When the bottom of the well is reached, the reverse program is started, the steel wire rope 13 is pulled up to start winding, so that the disc 10 returns upward. When the top of the well is reached, the movement stops.
