[0032] The moving mechanism 42 includes two groups of second threaded rods 424; Exemplarily, as Figure 6 shown.

[0033] Two lower clamps 421 are threadedly connected to each of the two second threaded rods 424. A second gear 422 is rotatably connected to the inner wall of each group of lower clamps 421. Two second guide wheels 423 are rotatably connected to one end of each group of lower clamps 421, and both of the two second guide wheels 423 extend into the cavity of the lower clamp 421. The cavities in the two lower clamps 421 are all sleeved on the bottom of the external gear ring 414, and both of the two second gears 422 are meshed with the external gear ring 414. The ends of the two second threaded rods 424 are rotatably connected to lower linkage blocks 425. A micro motor 426 is embedded at the top of each group of lower linkage blocks 425.

[0034] The collecting assembly 5 includes two collecting boxes 51; Exemplarily, as Figure 7 shown.

[0035] Both of the two collecting boxes 51 are fixedly connected to both sides of the outer wall of the lower clamp 421. Adsorption grooves 52 are opened at the tops of the two collecting boxes 51. Negative pressure fans are embedded in one side wall of each of the two collecting boxes 51. U-shaped pipes 53 are embedded in the outer walls of the two collecting boxes 51 and on the side close to the external gear ring 414. A high-definition camera 54 is embedded at the central axis center of the U-shaped pipe 53, and the high-definition camera 54 is electrically connected to the display screen.

[0038] Specifically, the steel pipe 10 to be cut horizontally moves on the feeding rollers 73 of the two inclined plates 72. By using the right-angle design at the connection part of the two inclined plates 72, the stability of the horizontal movement of the steel pipe 10 to be cut is increased. The first motor drives the first threaded rod 416, and the third motor drives the second threaded rod 424 to rotate, which is used to drive the threaded connection with the upper clamp 411 and the lower clamp 421, so that the external gear ring 414 horizontally moves, and the cutting position of the cutting blade teeth 415 and the steel pipe 10 to be cut is adjusted; After the output end of the first electric push rod 2 drives the lower linkage block 425 to fall, the external gear ring 414 and the cutting blade teeth 415 are synchronously moved downward. While the output end of the second motor drives the first gear 412 to rotate, the external gear ring 414 rotates at a high speed to cut the steel pipe 10 to be cut with the cutting blade teeth 415; The continuous operation of the negative pressure fan creates a negative pressure at the top and nearby of the adsorption tank 52 to adsorb the metal scraps near the cutting blade teeth 415. The adsorption holes 55 are used to clean the surface of the passing cutting blade teeth 415, always keeping the possibility of metal impurities remaining on the surface of the cutting blade teeth 415 and improving the cutting accuracy of the steel pipe; After the output end of the second electric push rod 3 extends into the positioning hole 418, and then the screw at the output end of the micro motor 426 is separated from the internal thread hole 419, the output end of the first electric push rod 2 drives the lower linkage block 425 to fall, so that the two second gears 422 cancel the meshing connection with the external gear ring 414, which is used to replace the external gear ring 414; The external gear ring 414 can also be meshed with the driving gear 9 after horizontal movement, and by manually rotating the handle 8, the detection personnel can watch the wear condition of the cutting blade teeth 415 on the external gear ring 414 through the display screen on one side of the handle 8. During the viewing process, the cutting blade teeth 415 are photographed in real time by the high-definition camera 54, which improves the precise maintenance and self-inspection of the cutting blade after each use.

[0039] The working principle of a green and environment-friendly steel pipe cutting device proposed by an embodiment of the present invention is as follows: By horizontally moving the feeding roller 73 of the steel pipe 10 to be cut on the two inclined plates 72, and using the right-angle design at the connection of the two inclined plates 72 to increase the stability of the horizontal movement of the steel pipe 10 to be cut. The first motor drives the first threaded rod 416 and the third motor drives the second threaded rod 424 to rotate, which are used to drive the threaded connection with the upper fixture 411 and the lower fixture 421, so that the external gear ring 414 moves horizontally to adjust the cutting position of the cutting blade teeth 415 and the steel pipe 10 to be cut; After the output end of the first electric push rod 2 drives the lower linkage block 425 to fall, the external gear ring 414 and the cutting blade teeth 415 are synchronously moved downward. While the output end of the second motor drives the first gear 412 to rotate, the external gear ring 414 rotates at a high speed to cut the steel pipe 10 to be cut with the cutting blade teeth 415; The continuous operation of the negative pressure fan creates a negative pressure at the top and nearby of the adsorption tank 52 to adsorb the metal scraps near the cutting blade teeth 415. The adsorption holes 55 are used to clean the surface of the passing cutting blade teeth 415, always keeping the possibility of metal impurities remaining on the surface of the cutting blade teeth 415 and improving the cutting accuracy of the steel pipe; After extending to the positioning hole 418 through the output end of the second electric push rod 3, and then separating the screw at the output end of the micro motor 426 from the internal thread hole 419, the output end of the first electric push rod 2 drives the linkage block 425 to drop, so that the two second gears 422 cancel the meshing connection with the external gear ring 414, which is used for replacing the external gear ring 414; The external gear ring 414 can also be meshed with the driving gear 9 after horizontal movement, and by manually rotating the handle 8, the detection personnel can watch the wear condition of the cutting blade teeth 415 on the external gear ring 414 through the display screen on one side of the handle 8. During the viewing process, the cutting blade teeth 415 are photographed in real time by the high-definition camera 54, which improves the accurate maintenance and self-check of the cutting blade after each use.

[0040] Based on the above-mentioned green environmental protection type steel pipe cutting equipment, the embodiment of the present invention also provides a cutting method for the green environmental protection type steel pipe cutting equipment, including the following steps, The bottom of the cutting assembly moves downward under the action of the four first electric push rods; The rotating cutting assembly cuts the steel pipe to be cut; The collecting assembly collects the waste chips during the cutting process, and the two conduit assemblies guide the steel pipe to be cut; The steel pipe to be cut is freely adjusted to different positions relative to the cutting assembly.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
