Technical Field

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

[0002] Currently, shaft inspection operations mainly rely on manual labor, but this method has many limitations, such as limited accuracy, low efficiency, and easy omissions, making it difficult to meet the high standards required for deep shaft inspection. To solve these problems, coal mine safety monitoring robots have been introduced in China. With their advantages of ease of operation, high efficiency, and flexibility, they are very suitable for performing shaft inspection tasks.

[0003] Therefore, developing an intelligent unmanned inspection system for deep wells and using emerging technologies to achieve regular unmanned inspections of vertical shafts, ensuring the safety of the shaft passage, improving risk prevention and control capabilities, and providing accurate information for the safety of vertical shaft passages are of great significance to the safe production and digital transformation of mining areas.

[0004] For ultra-deep vertical shafts, the inspection intelligent robot needs to ensure stable operation. Furthermore, since ground-penetrating radar may be affected by certain factors in the air-coupled mode, resulting in blurred detection images, more advanced detection methods and systems are required.

[0005] To ensure the accuracy of inspection results, intelligent inspection equipment needs to perform close-range, detailed detection of areas with blurred images and conduct comprehensive inspections to ensure the provision of accurate and reliable inspection data.

[0006] This means that intelligent inspection equipment must have high-precision detection capabilities and be able to effectively collect and analyze images in complex environments, thereby ensuring the accuracy and reliability of inspection data. Summary of the Invention

The purpose of this utility model is to use an electric push rod to drive the fork to rotate to the inner wall of the well barrel for support, thereby causing the ejection plate to rotate out with the mobile ground-penetrating radar. A gravity block is used to keep the mobile ground-penetrating radar in a horizontal state, allowing the radar to be close to the detection area, thus achieving a close-proximity detection mode to solve the above problems.

[0035] like Figure 7As shown, the rod 19 is installed in the rotation hole 181 of the electric push part 18. The rod 19 is installed in the slide groove 28 of the two sets of forks 25 through the crossbar 191. The side block 192 is located on the side of the two sets of forks 25. The crossbar 191 is stabilized by the side block 192. The slide bar 27 of the two sets of forks 25 is installed in the slide groove 21 of the extension plate 20. The plate 30 is installed in the mounting hole 241 of the notch 24 through the mounting shaft 33.

[0036] like Figure 2 , Figure 3 As shown, the two sets of fork rods 25 are installed in the mounting holes 121 of the protruding plate 12 via the mounting shaft 26, the protruding plate 20 is installed in the mounting holes 131 of the protruding plate 13 via the mounting shaft 22, and the electric pusher 18 is installed on the rotating shaft 152 of the bottom column 15 via the rotating hole 181.

[0041] The basic principle of this utility model:

[0042] like Figure 1 As shown, when the device receives the detection command, it pulls the steel wire rope 101 to release the line, thereby causing the base 10 to move downward along the positioning steel wire rope 17 through the steel wire rope hole 103 to perform detection. At this time, the extension plates 20 are all retracted into the side groove 11 of the base 10. The fixed ground penetrating radar 102 and the mobile ground penetrating radar 31 work together to perform circular line detection. At the same time, the three-dimensional laser scanner 41, CCD camera 43 and light source 44 work synchronously to perform three-dimensional scanning and image acquisition detection.

[0043] When an unidentified defect is detected, the electric pusher 18 drives the rod 19 outward. Through the cooperation of the crossbar 191 and the first slide groove 21, the two sets of forks 25 rotate around the second mounting hole 121 via the cooperation of the second mounting shaft 26 and the second mounting hole 121. This, in turn, causes the extension plate 20 to rotate in the opposite direction around the third mounting hole 131 via the cooperation of the slide rod 27 and the first slide groove 21, thus unfolding the extension plate 20. The flexible ends 29 of the two sets of forks 25 are then supported on the inner wall of the shaft. The extension plate 20, carrying the flat plate 30, moves to the inspection location. During this process, the flat plate 30 rotates through the cooperation of the third mounting shaft 33 and the fourth mounting hole 241, and the weight of the counterweight 35 keeps the flat plate 30 horizontal. This ensures that the mobile ground-penetrating radar 31 remains horizontally facing the inspection location, and is secured by the electromagnet 34. The mobile ground-penetrating radar 31 then performs close-range detection, achieving... Figure 2 The working status is shown;

[0044] After the proximity test is completed, the device will respond as follows: Figure 1 As shown in the diagram, the steel wire rope 101 is then pulled up to continue releasing the line, causing the base 10 to probe downwards.

[0045] When the bottom of the well is reached, the reverse program is initiated, the steel wire rope 101 is pulled up to start winding, and the base 10 returns upward. When the top of the well is reached, the movement stops.
