Description

Technical Field

[0001] This utility model belongs to the field of cutting technology, and in particular relates to a composite insulation pipe cutting device. Background Technology

[0002] Thermal insulation pipe is short for heat-insulated pipeline. It is used for transporting liquids, gases, and other media in industries such as petroleum, chemical, aerospace, hot springs, military, district heating, central air conditioning, and municipal engineering. It is often a composite pipe with a double layer of steel pipe filled with insulating material. During production and installation, the composite thermal insulation pipe requires cutting and processing.

[0003] Patent No. CN212552183U discloses a novel composite insulation pipe cutting device, comprising a composite insulation pipe. An upper frame and a lower frame are respectively provided on the upper and lower surfaces of the composite insulation pipe. Guide rails are fixedly connected to the outer sides of both the upper and lower frames. Movable seats are slidably connected to the surfaces of the guide rails. A gas cutting gun fixing device is fixedly connected to one side of the movable seat. A handle is fixedly connected to the front end of the movable seat. Battery irons are provided on the inner walls of both the upper and lower frames. The two ends of the upper frame are snap-fitted to the two ends of the lower frame and fixedly connected by pins. This utility model relates to the field of pipe cutting technology. This novel composite insulation pipe cutting device solves the problems of traditional cutting devices being large in size, having multiple structures, being complex to install and operate, being difficult to transport, having low convenience, and having great limitations in practical application.

[0004] In existing technologies, the cutting device is made more compact and easier to carry and transport by setting pins and movable seats. However, the following problems still exist in its overall use. First, the insulation pipe is quite tough. When cutting it, it is often fixed to both ends of the insulation pipe by external fixing devices. This causes the middle section of the insulation pipe to sag due to gravity during cutting, resulting in a slight bounce when the insulation pipe is subjected to the impact of cutting. This leads to a large number of burrs and flash at the cut. Second, a large amount of debris is generated on the surface of the insulation pipe during cutting. The debris remains on the surface of the insulation pipe, affecting the positioning of the cutting device and reducing the cutting accuracy. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a composite insulation pipe cutting device. By setting up an installation shell, clamping rod, and support rod, the insulation pipe can be fixed near the cutting point during the cutting process, thereby reducing the bounce of the insulation pipe and effectively improving the cutting quality. By setting up a gas connector, gas nozzle, and gas chamber, the surface of the insulation pipe can be cleaned during the cutting process, reducing waste residue and improving the cutting accuracy.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example 1:

[0027] refer to Figure 1 and Figure 2 A composite thermal insulation pipe cutting device includes a base 10, two support rollers 11 rotatably mounted on the end faces of the two bases 10, a mounting base 14 slidably mounted between the two bases 10, a mounting shell 12 on one side of the mounting base 14, two clamping rods 13 extending outward from the interior of the mounting shell 12, a drive ring 15 rotatably mounted inside the mounting base 14, a driven ring 16 rotatably mounted inside the drive ring 15, two cutting shafts 17 rotatably mounted outside the driven ring 16, a blade 43 mounted at one end of each of the two cutting shafts 17, a gas connector 18 mounted outside the mounting base 14, and multiple gas nozzles 19 mounted on the inner circular surface of the mounting base 14.

[0028] In this scheme, multiple support rollers 11 are divided into two groups and symmetrically arranged on the end faces of the two bases 10. By setting two groups of support rollers 11, the insulation pipe can be supported to prevent the insulation pipe from sagging at both ends during cutting and damaging the insulation pipe, thereby improving the safety of the insulation pipe. The mounting base 14 is L-shaped, and the protruding end face of the mounting base 14 is fixedly connected to the mounting shell 12, so that the mounting shell 12 is tightly attached to the cutting area, thereby effectively fixing the insulation pipe.

[0029] refer to Figure 3 , Figure 4 , Figure 5 and Figure 6The outer surface of the drive ring 15 is provided with an adjustment groove 44. A rotating connector 28 is provided on the inner wall of the adjustment groove 44. An adjustment cylinder 29 is rotatably mounted at one end of the rotating connector 28. A connecting block 30 is provided on the output end of the adjustment cylinder 29. The connecting block 30 is fixedly connected to the driven ring 16. A protrusion 42 is provided on the outer surface of the driven ring 16. The protrusion 42 is slidably connected to the drive ring 15. A sliding groove 25 is provided on the outside of the drive ring 15. A first connecting shaft 26 is slidably mounted inside the sliding groove 25. The connecting shaft 26 is fixedly connected to the cutting shaft 17. The cutting shaft 17 is provided with a second connecting shaft 27 inside. The second connecting shaft 27 is rotatably connected to the drive ring 15. A support block 20 is provided on one side of the drive ring 15 on the inner wall of the mounting base 14. A bearing sleeve 21 is provided between the support block 20 and the drive ring 15. A toothed ring 22 is provided on the outer circumference of the drive ring 15. A drive gear 23 is rotatably provided on one side of the toothed ring 22 on the outer surface of the mounting base 14. The toothed ring 22 and the drive gear 23 are meshed and connected for transmission.

[0030] In this design, the drive ring 15 is annular in shape, and a mounting groove is provided on its outer surface. The support block 20 is slidably connected in the mounting groove of the drive ring 15. By providing the support block 20, the drive ring 15 can be supported, thereby improving its stability. The driven ring 16 is annular in shape and is slidably connected to the inner surface of the drive ring 15 by a protrusion 42 on its outer surface. The connecting block 30 on the outer surface of the driven ring 16 extends into the mounting groove of the drive ring 15. A drive motor is provided inside the mounting base 14, and the output shaft of the drive motor is fixedly connected to the drive gear 23. During cutting, the adjusting cylinder 29 is activated. The output shaft of the adjusting cylinder 29 pushes the connecting block 30, causing the driven ring 16 at one end of the connecting block 30 to rotate. During the rotation of the driven ring 16, the second connecting shaft 27 on the end face rotates closer to the slide groove 25, causing the first connecting shaft 26 to slide inside the slide groove 25. This causes the end of the cutting shaft 17 with the blade to move closer to the center, thereby cutting the blade into the surface of the insulation pipe. By adjusting the length of the output shaft of the cylinder 29, the depth of the blade cutting into the insulation pipe can be controlled, thereby improving the adaptability of the device.

[0031] refer to Figure 7 and Figure 8 The mounting housing 12 has a sliding block 32 inside, and a support rod 33 is provided on the top end face of the sliding block 32. Both the support rod 33 and the clamping rod 13 have clamping rollers 31 at their top ends. The surface of the sliding block 32 has two drive grooves 34 symmetrically arranged. Both drive grooves 34 have drive shafts 35 slidably arranged inside them. One end of the drive shaft 35 has a drive plate 36. The drive plate 36 has a limit groove 37 inside, and a driven shaft 38 is slidably arranged inside the limit groove 37. The driven shaft 38 is fixedly connected to the clamping rod 13, and the drive plate 36 is rotatably connected to the mounting housing 12.

[0032] In this design, the two clamping rods 13 are arc-shaped and symmetrically arranged inside the mounting shell 12; the sliding block 32 is trapezoidal in shape, with the two inclined sides of the trapezoid having an arc surface design, and the other end of the clamping rod 13 abuts against the arc surface of the sliding block 32; the drive plate 36 is triangular in shape, with the first corner fixedly connected to the drive shaft 35, the second corner rotatably connected to the interior of the mounting shell 12, and the third corner slidably connected to the driven shaft 38; a clamping cylinder is installed inside the mounting shell 12, and the output shaft of the clamping cylinder is fixedly connected to the bottom end face of the sliding block 32; by setting the drive plate 36, the clamping rods 13 on the two inclined surfaces can be rotated when the sliding block 32 moves upward, and the angle of the two clamping rods 13 can be limited by the drive plate 36, so that the two clamping rods 13 form a movement mode of clamping towards the center, thereby achieving the effect of clamping and fixing the insulation pipe.

[0033] refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 The mounting base 14 has an air chamber 24 inside, which is connected in series with the gas connector 18 and the gas nozzle 19.

[0034] In this design, an air pump 41 is provided on one side of the mounting base 14. The output end of the air pump 41 is connected to a hose, and the other end of the hose is connected to a gas connector 18. Gas is delivered into the air chamber 24 through the air pump 41 and then sprayed out by the gas nozzle 19 to clean the cutting area and reduce the residue of impurities.

[0035] refer to Figure 1 A slide rail 39 is provided between the two bases 10, and a slider 40 is slidably provided on the end face of the slide rail 39. The slider 40 is fixedly connected to the mounting base 14.

[0036] In this design, by setting the slide rail 39 and the slider 40, the mounting base 14 can slide back and forth, thereby adjusting the position of the mounting base 14. The slide rail 39 itself has a self-locking function, which can prevent sliding during the cutting process, thereby improving the flexibility of the mounting base 14 and increasing the overall stability of the device during cutting.

[0037] In use, the insulation pipe is placed horizontally on the surface of the two sets of support rollers 11, and the insulation pipe is passed through the center of the driven ring 16. Then, the position of the mounting base 14 is moved by the slider 40. When the position is appropriate, the clamping cylinder is activated. The output shaft of the clamping cylinder pushes the sliding block 32 to move upward. The sliding block 32 pushes the top support rod 33 to move upward, so that the support rod 33 supports the insulation pipe. At the same time, the upward movement of the sliding block 32 pushes the clamping rods 13 on the two inclined surfaces, causing the two clamping rods 13 to rotate relative to each other. During the rotation, the driving force on the surface of the sliding block 32... The moving groove 34 pushes the drive shaft 35 to slide, and the drive shaft 35 drives the drive plate 36 to rotate to both sides. At the same time, the driven shaft 38 on the end face of the clamping rod 13 slides upward along the limiting groove 37, so that the two driven shafts 38 slide relative to each other. The driven shaft 38 drives one end of the clamping rod 13 to move, so that the connection between the clamping rod 13 and the mounting shell 12 rotates. During this period, the drive plate 36 limits the angle of the two clamping rods 13, so that the two clamping rods 13 form a movement mode of clamping towards the center, thereby achieving the effect of clamping and fixing the heat preservation pipe.

[0038] When cutting the insulation pipe, the adjusting cylinder 29 is activated. The output shaft of the adjusting cylinder 29 pushes the connecting block 30 and drives the driven ring 16 at one end of the connecting block 30 to rotate. During the rotation of the driven ring 16, the second connecting shaft 27 on the end face rotates closer to the slide groove 25, so that the first connecting shaft 26 slides inside the slide groove 25. This causes the end of the cutting shaft 17 with the blade to move closer to the center, thereby cutting the blade into the insulation pipe. The extension length of the cylinder can be adjusted as needed to adjust the length of the blade cutting into the insulation pipe.

[0039] Then the drive motor is started, and the output shaft of the drive motor drives the drive gear 23 to rotate. The drive gear 23 drives the gear ring 22 to rotate, and the gear ring 22 drives the drive ring 15 to rotate, so that the drive ring 15 drives the two cutting shafts 17 on the end face to rotate. Then the two cutting shafts 17 cut the insulation pipe when they rotate.

[0040] During the cutting process, the air pump 41 is activated, supplying gas into the air chamber 24, which is then ejected from the gas nozzle 19 to clean the insulation tube in a ring-shaped airflow, reducing the residue of impurities.
