The cutting depth adjustment device includes at least two rollers 3, an adjustment seat 4 and a lifting mechanism 5; each roller 3 is rotatably arranged at the bottom of the main structure 1; each roller 3 can slide along the height direction of the main structure 1, and each roller 3 is in contact with the outer peripheral wall of the pipe; wherein, there is a height difference between the lowest position of the roller 3 and the lowest position of the scraper 2; the adjustment seat 4 is slidably arranged on the main structure 1 along the height direction of the main structure 1; there are several adjustment seats 4, and they correspond to the rollers 3 one by one; the rollers 3 rotate and cooperate with the corresponding adjustment seats 4; the lifting mechanism 5 is arranged on the main structure 1; the lifting mechanism 5 is used to drive the adjustment seat 4 to rise and fall.
[0030] The utility model provides a cutting depth adjustment device for a wall-climbing scraping device. Compared with the prior art, after the main structure 1 is installed on the plastic pipe, the height of the adjustment seat 4 is adjusted to adjust the difference between the lowest position of the roller 3 and the lowest position of the scraper 2, that is, the cutting depth is adjusted; after the adjustment is completed, the roller 3 contacts the outer peripheral wall of the plastic pipe, so that the cutting depth of the scraper 2 remains unchanged; after the main structure 1 rotates circumferentially around the plastic pipe, the cutting depth on the plastic pipe can be made more uniform, reducing the occurrence of uneven cutting depth.
[0031] Exemplarily, this embodiment is described by taking two rollers 3 as an example. The two rollers 3 are respectively located on both sides of the scraper 2. The adjustment seat 4 is an N-shaped structure. The adjustment seat 4 forms a rotation space, and the rollers 3 are located in the rotation space of the adjustment seat 4. The diameter of the rollers 3 is greater than the length of the curved portion of the adjustment seat 4, so that the rollers 3 can contact the outer peripheral wall of the plastic pipe. Through the above arrangement, after the position of the adjustment seat 4 is changed, the rollers 3 can still contact the outer peripheral wall of the pipe, and when the main structure 1 moves circumferentially around the plastic pipe, the rollers 3 can rotate in coordination with the plastic pipe. The adjustment heights of the rollers 3 on both sides of the scraper 2 can be consistent or inconsistent. When the heights of the rollers 3 on both sides are inconsistent, the line connecting the lowest positions of the rollers 3 on both sides passes through the scraper 2, and the farthest distance between the bottom of the scraper 2 and the above line is the cutting depth.
[0032] In some embodiments, Figures 1 to 5 As shown, the bottom of the main structure 1 has a slide 11, and the adjustment seat 4 is slidably matched with the slide 11; the side wall of the slide 11 has a guide groove 12, and the adjustment seat 4 is connected to a guide slider 41, and the guide slider 41 is slidably matched with the guide groove 12; the guide groove 12 is connected to the bottom of the main structure 1.
[0033] It should be noted that the slide 11 arranged at the bottom of the main structure 1 can provide space for the lifting and lowering of the adjustment seat 4. The guide groove 12 on the side wall of the slide 11 slides with the guide slider 41 on the adjustment seat 4, which can guide the sliding direction of the adjustment seat 4 and make the adjustment seat 4 more stable during the adjustment process.
[0034] In some embodiments, Figures 1 to 5 As shown, the two ends of the adjustment seat 4 are in contact with the two ends of the slideway 11 respectively, and the lifting mechanism 5 includes an adjustment part 51 and a screw rod 52. The adjustment part 51 is slidably arranged in the slideway 11 of the main structure 1; the adjustment part 51 is detachably connected to the adjustment seat 4; the screw rod 52 is rotatably arranged at the position of the main structure 1 on the slideway 11; the adjustment part 51 has a threaded hole threadedly matched with the screw rod 52.

[0035] It should be noted that the positions of the screw 52 and the protrusion 14 are relatively fixed, that is, the screw 52 and the protrusion 14 are rotationally matched, and the screw 52 does not slide along the axial direction. By rotating the screw 52, the adjustment portion 51 can slide along the axial direction of the screw 52, thereby driving the adjustment seat 4 to slide, so that the height of the roller 3 can be adjusted. The height of the roller 3 can be fine-tuned by the number of turns of the screw 52.

[0037] It should be noted that the adjusting portion 51 is slidably matched with the guide column 15 , so that the adjusting portion 51 can slide up and down smoothly during the rotation of the screw rod 52 , thereby preventing the adjusting portion 51 from rotating around the axis of the screw rod 52 .
[0038] In some embodiments, Figures 1 to 5 As shown, the top of the adjustment seat 4 is provided with a connecting sleeve 42 , and the adjustment portion 51 is provided with a connecting column 53 which is plugged into and matched with the connecting sleeve 42 ; the connecting column 53 and the connecting sleeve 42 are fixed by a pin shaft 54 .

[0041] It should be noted that when connecting the adjustment part 51 and the adjustment seat 4, the through hole on the adjustment part 51 is aligned with the threaded sleeve on the adjustment seat 4, and then the adjustment part 51 and the threaded sleeve are fixed by the fixing bolt, so that the adjustment part 51 can be fixed on the adjustment seat 4. When disassembling, the disassembly between the adjustment part 51 and the adjustment seat 4 can be completed by unscrewing the fixing bolt.
[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
