Although these two methods meet the basic cutting needs to a certain extent, they face many challenges and limitations in actual applications. The manual cutting method relies on the skills and experience of the operator, requires a lot of manpower, and takes a long time to operate. The accuracy and consistency of this method are difficult to guarantee, especially when dealing with pipes with high precision requirements, errors and defects will occur. Manual operation is more difficult in the field or in complex environments, which is not only inefficient, but also difficult to ensure the safety of operators.

Although it improves cutting efficiency and accuracy to a certain extent, some auxiliary cutting devices have problems such as complex structure and inconvenient operation. These devices require high skills from operators and require special training to master them, which reduces the efficiency of cutting operations. Utility Model Content

DETAILED DESCRIPTION
[0026] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.
[0027] When cutting pipes with auxiliary cutting devices, although the cutting efficiency and accuracy can be improved to a certain extent, some auxiliary cutting devices are complex in structure and inconvenient to operate. These devices require high skills from the operators and require special training to master them, which reduces the efficiency of the cutting operation.
[0028] In order to solve the problem that the auxiliary cutting device is complicated in structure and inconvenient to operate during the pipe cutting operation, the present application provides a pipe auxiliary cutting device, see Figure 1 The device includes: a liner 11, a casing 12, a connecting plate 21 and a clamp 23, wherein the liner 11 is sleeved on the outside of the pipe 13, and the liner 11 is fixedly connected to the pipe 13; the casing 12 is sleeved on the outside of the liner 11, and the casing 12 is rotatably connected to the liner 11. In order to improve the strength of the device and facilitate processing, in some embodiments, the liner 11, the casing 12, the connecting plate 21 and the clamp 23 can all be made of metal, for example, ordinary carbon steel. During field operations, since a portion of the pipe 13 is buried underground for a long time, rust will appear on the surface, making the outer surface rough. By sleeved the liner 11 on the outside of the pipe 13, the casing 12 is rotated on the outside of the liner 11, which can not only reduce the resistance of the casing 12 during rotation and improve the stability of the device, but also reduce the damage to the pipe 13 during rotation.
[0029] The liner 11 includes a first liner 111 and a second liner 112. The first liner 111 and the second liner 112 are arc structures. In some embodiments, the lengths of the first liner 111 and the second liner 112 can be the same, and the arc lengths of the first liner 111 and the second liner 112 are equal. The two ends of the arc of the first liner 111 are respectively provided with a clamping groove 113. The clamping groove 113 can be a U-shaped structure. The clamping groove 113 can be respectively fixed to the two ends of the arc of the first liner 111 by welding. The two ends of the arc of the second liner 112 are respectively provided with a clamping block 14. One end of the clamping block 14 is hinged to the second liner 112, and the other end of the clamping block 14 is clamped to the clamping groove 113. It can be understood that the opening direction of the clamping groove 113 is along the direction of the line connecting the two ends of the arc of the first liner 111 toward the outside of the first liner 111, so that the clamping block 14 can be clamped to the clamping groove 113 and limited by the clamping groove 113.
[0030] A card slot 113 can be provided at both ends of the first liner 111, and a card block 14 can be provided at both ends of the second liner 112, that is, four card slots 113 are provided on the first liner 111, and four card blocks 14 are provided on the second liner 112, so that the two ends of the first liner 111 and the second liner 112 can be respectively connected, so as to improve the reliability of the connection between the first liner 111 and the second liner 112, and reliably fix the first liner 111 and the second liner 112 on the outside of the pipe 13. By providing the card slot 113 and the card block 14 for connection, the first liner 111 and the second liner 112 can be quickly connected, and the structure is simple and the operation is convenient. And because the first liner 111 and the second liner 112 are detachably connected, the liner 11 can be conveniently moved, and the liner 11 can be placed at any position of the pipe 13 where cutting is required, and can adapt to pipes 13 of different lengths and sizes.
[0031] See also Figure 2-3 A limiting groove 114 is circumferentially arranged on the outer sides of the first lining plate 111 and the second lining plate 112. The limiting groove 114 may also be U-shaped. It should be noted that in order to ensure the strength of the first lining plate 111 and the second lining plate 112, the thickness of the first lining plate 111 and the second lining plate 112 should not be less than 6 mm.
[0032] The sleeve 12 includes two symmetrically arranged bent plates 121, which are detachably connected to the limiting groove 114. Since the sleeve 12 is rotatably connected to the liner 11, the two bent plates 121 can rotate relative to the first liner 111 and the second liner 112 in the limiting groove 114. In some embodiments, the width of the bent plate 121 can be set equal to the width of the limiting groove 114. When the bent plate 121 rotates, it can be axially limited by the limiting groove 114 to prevent the bent plate 121 from deflecting during the rotation process. One end of the connecting plate 21 is detachably connected to the bent plate 121, and the other end of the connecting plate 21 is detachably connected to the clamp 23, and the clamp 23 is used to clamp the cutting device.
[0033] When it is necessary to cut the pipe 13, the cutting device is adjusted to the position of the pipe 13 to be cut, the pipe 13 is aligned, the bent plate 121 is rotated, and the clamped cutting device can cut the pipe 13 along the circumferential direction; by setting the bent plate 121 in the limiting groove 114, the cutting device always moves along a straight line during the cutting process, so that the cross section of the pipe 13 after cutting is flat, which can meet the cutting accuracy. The cutting device provided by the above embodiment is not only simple in structure, but also easy to operate, which can improve the working efficiency.
[0034] It should also be noted that the inner diameter of the first liner 111 and / or the second liner 112 is equal to the outer diameter of the pipe 13, and the arc length of the first liner 111 and / or the second liner 112 is less than a semicircle, so that the first liner 111 and the second liner 112 can be fixed to the outside of the pipe 13 by snap connection. In some embodiments, the inner diameter of the first liner 111 and / or the second liner 112 can also be set to be larger than the outer diameter of the pipe 13, but the difference between the inner diameter of the first liner 111 and / or the second liner 112 and the outer diameter of the pipe 13 should be as small as possible, for example, the difference can be within 4 mm, to prevent the first liner 111 and the second liner 112 from affecting the rotation of the sleeve 12 after assembly.
[0035] See again Figure 1 And 3, the block 14 is a T-shaped structure, and the block 14 includes a horizontal portion and a vertical portion, one end of the vertical portion is connected to the horizontal portion, and the other end of the vertical portion is hinged to the second lining plate 112. In some embodiments, a clamping groove 113 can be provided at both ends of the arc of the second lining plate 112, and a connecting hole can be provided on the side perpendicular to the clamping groove 113. The end of the vertical portion away from the horizontal portion is provided in the clamping groove 113 on the second lining plate 112 and is hinged to the connecting hole on the side of the clamping groove 113. After one end of the vertical portion connected to the horizontal portion enters the clamping groove 113, the horizontal portion is clamped with the clamping groove 113 and is limited by the clamping groove 113, so that the first lining plate 111 and the second lining plate 112 can be quickly fixed on the outside of the pipeline 13.
[0036] The bent plate 121 is a semicircular structure. Since the bent plate 121 is sleeved in the limiting groove 114, the inner diameter of the bent plate 121 is larger than the inner diameter of the first lining plate 111 and / or the second lining plate 112, and smaller than the outer diameter of the first lining plate 111 and / or the second lining plate 112. It can be understood that the inner diameter of the bent plate 121 is related to the radius of the bottom surface of the limiting groove 114, so that the bent plate 121 can rotate around the limiting groove 114. The outer diameter of the bent plate 121 and the two ends of the arc of the bent plate 121 are respectively provided with first connecting ears, and the two bent plates 121 are detachably connected through the first connecting ears. A handle 123 is provided on the outside of the bent plate 121. The handle 123 is used to rotate the sleeve 12. The handle 123 can be fixed on the outside of the bent plate 121 by welding. The handles 123 on the outside of the two bent plates 121 should be symmetrically arranged to improve the balance of the sleeve 12 during rotation.
[0037] The connecting plate 21 includes a connecting portion 211 and a rotating portion 212. The connecting portion 211 may be a rectangular plate. One end of the connecting portion 211 is detachably connected to the bent plate 121. For example, a first adjustment hole 124 may be provided on the side of the handle 123. One end of the connecting portion 211 is detachably connected to the handle 123 through the first adjustment hole 124. The other end of the connecting portion 211 is connected to one end of the rotating portion 212. The rotating portion 212 may also be a rectangular plate. The other end of the rotating portion 212 is detachably connected to the clamp 23. The clamp 23 may be provided on the side of the rotating portion 212. A second adjustment hole 213 may be provided at one end of the rotating portion 212 where the clamp 23 is provided, so that the clamp 23 is detachably connected to the rotating portion 212 through the second adjustment hole 213. The first adjustment hole 124 and the second adjustment hole 213 are long holes. By setting the first adjustment hole 124 with a long structure, the distance between the connecting plate 21 and the pipe 13 can be adjusted, and then the distance between the cutting device and the pipe 13 can be adjusted; by setting the second adjustment hole 213 with a long structure, the position of the cutting device can be adjusted along the axial direction of the pipe 13, so that the cutting device can be aligned with the position of the pipe 13 to be cut.
[0038] In some embodiments, a connecting column is further provided at one end of the rotating part 212 away from the clamp 23, a boss 214 is provided at one side of the connecting part 211, a locking hole is provided on the boss 214, and after the connecting column is rotatably connected with the boss 214, the connecting column is limited by the locking hole. The connecting column can be fixed to the rotating part 212 by welding, and a through hole is provided on the side of the boss 214. After the connecting column is inserted into the through hole, the connecting column can rotate in the boss 214 to adjust the angle of the cutting device. After the cutting device is adjusted, a tightening screw is screwed into the locking hole to tighten the connecting column by the tightening screw, thereby limiting the cutting device.
[0039] The clamp 23 may also be an arc structure, and the arc length of the clamp 23 may be set to be less than a semicircle, so that the clamp 23 can clamp cutting devices of different diameters. Second connecting ears are provided at both ends of the arc of the clamp 23, and threaded holes are provided on the second connecting ears, so that the clamp 23 can be detachably connected to the rotating part 212 through the threaded holes and the second adjustment hole 213.
[0040] It can be seen from the above technical scheme that the embodiment of the present application provides a pipeline auxiliary cutting device, including: a liner 11, a sleeve 12, a connecting plate 21 and a clamp 23; the liner 11 is sleeved on the outside of the pipeline 13 and fixedly connected to the pipeline 13; the sleeve 12 is sleeved on the outside of the liner 11, and the sleeve 12 is rotatably connected to the liner 11. The liner 11 includes a first liner 111 and a second liner 112, and the two ends of the arc of the first liner 111 are respectively provided with a clamping groove 113, and the two ends of the arc of the second liner 112 are respectively provided with a clamping block 14, one end of the clamping block 14 is hinged to the second liner 112, and the other end is clamped to the clamping groove 113. The sleeve 12 includes two symmetrically arranged bent plates 121, and the outer sides of the first liner 111 and the second liner 112 are provided with a limiting groove 114 along the circumferential direction, and the two bent plates 121 are detachably connected to the limiting groove 114. One end of the connecting plate 21 is detachably connected to the bent plate 121, and the other end is detachably connected to the clamp 23, and the clamp 23 is used to clamp the cutting device. The first lining plate 111 and the second lining plate 112 are fixed to the outside of the pipe 13 by means of a snap connection, which is convenient for assembly; the bent plate 121 is sleeved in the limiting groove 114 by means of a detachable connection, so that during the cutting process, the cutting device moves in a straight line, which can meet the cutting accuracy. When the cutting operation is required, the bent plate 121 is rotated to cut the pipe 13 in the circumferential direction. The device is not only simple in structure, but also easy to operate, which can solve the problem that the auxiliary cutting device has a complex structure and is inconvenient to operate in the pipe cutting operation.
