Description

Technical Field

[0001] This utility model relates to the field of endoscope guidance technology, specifically to an industrial endoscope guidance device for boiler inspection. Background Technology

[0002] Industrial endoscopes are multidisciplinary testing devices, mainly used for non-destructive testing. They can detect and observe the internal structure of an object without disassembling or damaging it. However, endoscopes are generally inserted into the interior of a boiler using conductive wires, which makes it difficult to guide the endoscope properly. Therefore, a guiding device is needed to adjust its position.

[0003] An existing patent application (CN218938650U) discloses an industrial endoscope guide device for boiler inspection. The device includes a boiler pipe, a connecting pipe fixedly connected to the top of the boiler pipe, an adjusting mechanism on the connecting pipe, and two limiting components on the connecting pipe. The adjusting mechanism includes a connecting cover slidably connected to the top of the connecting pipe, a protective tube rotatably connected inside the connecting cover, a cable inside the protective tube, an endoscope body mounted on the left side of the protective tube, and two connecting plates fixedly connected to the top of the connecting cover. This industrial endoscope guide device for boiler inspection, through its adjusting mechanism, enables angle adjustment of the endoscope body, allowing for precise positioning of the endoscope body, thus ensuring the quality of boiler inspection, facilitating user operation, and increasing the practicality of the guide device.

[0004] When inspecting the inside of a boiler, an endoscope needs to be able to observe all positions. However, the angle of the device is easily limited during the inspection, which can lead to blind spots and affect the accuracy of the inspection. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 The present invention provides an embodiment of an industrial endoscope guide device for boiler inspection, comprising a boiler pipe 1, an installation pipe 10 at the top of the boiler pipe 1, a connecting bearing 8 inside the installation pipe 10, an outer sleeve 9 inside the connecting bearing 8, a guide ring inside the installation pipe 10, the outer sleeve 9 inside the guide ring, a rotating plate 4 at the top of the outer side of the outer sleeve 9, an inner sleeve 3 inside the outer sleeve 9, a pull plate 7 at the top of the inner sleeve 3, a probe wire 2 inside the inner sleeve 3, a hemispherical limiting groove 18 at the bottom of the outer sleeve 9, and a hemispherical slider 17 at the bottom of the inner sleeve 3. The hemispherical slider 17 and the hemispherical limiting groove 18 are hemispherical in structure, and the hemispherical slider 17 and the hemispherical limiting groove 18 are adapted to each other so that the hemispherical slider 17 can be twisted inside the hemispherical limiting groove 18. The hemispherical slider 17 is located inside the hemispherical limiting groove 18, and the probe wire 2 is located inside the hemispherical slider 17.

[0022] The bottom of the hemispherical slider 17 is symmetrically provided with mounting plates 16 on both sides. A connecting rod 12 is located inside the mounting plate 16. A mounting hole is provided on one side of the mounting plate 16, and the connecting rod 12 is located inside the mounting hole to facilitate rotation of the mounting plate 16. A retaining ring 15 is provided between the two sets of connecting rods 12. The end of the probe wire 2 is located inside the retaining ring 15. A probe 14 is provided at the bottom of the probe wire 2. A through hole is provided at the top of the hemispherical slider 17, and the bottom of the probe 14 extends through the through hole to the bottom of the hemispherical slider 17 for easy... For positioning and connection, a gear 13 is provided on the outer side of the connecting rod 12, a guide hole 19 is provided on one side of the top of the hemispherical slider 17, a rack 11 is provided inside the guide hole 19, the rack 11 meshes with the gear 13, a pull rod 5 is provided on the top of the gear 13, a connecting hole is provided on the top of the pull plate 7, the bottom of the pull rod 5 extends into the interior of the outer sleeve 9 through the connecting hole, so as to facilitate the overall rotation of the outer sleeve 9, and a rubber limiting ring 6 is provided on the top of the outer side of the pull rod 5, the inner diameter of the rubber limiting ring 6 is smaller than the diameter of the pull rod 5.

[0023] Working principle: During boiler inspection, probe wire 2 and probe 14 are first inserted through the inner sleeve 3, and then through the hemispherical slider 17 into the retaining ring 15. This completes the insertion of probe wire 2 and probe 14. When adjusting the angle, for small adjustments, the inner sleeve 3 is pulled and twisted, causing the hemispherical slider 17 to slide along the hemispherical limiting groove 18, thereby adjusting the position of the retaining ring 15. This changes the angle at probe 14, thus adjusting the position of probe 14. For larger adjustments, the angle is adjusted accordingly. During observation, first adjust the position of the rubber limiting ring 6, then pull the lever 5 to move it, causing the lever 5 to move the rack 11. As the rack 11 moves, it drives the gear 13 and the connecting rod 12 to rotate. Then the connecting rod 12 drives the gear 13 to rotate, thereby causing the probe wire 2 to bend, thus adjusting the position of the probe 14. Then twist the gear 13 to observe, so that the probe 14 can observe other positions. After the observation is completed, put the rubber limiting ring 6 back on the outside of the lever 5 to limit the lever 5 and prevent it from moving.
