Description

Technical Field

[0001] This invention relates to a membrane removal device, and more specifically, to a multifunctional pipe membrane removal device for removing membranes coated or plated on the inner or outer surface of pipes. Background Technology

[0002] Piping used in the construction and building sector can be created by welding pipes of specified lengths together.

[0003] Generally, after the pipes are manufactured, a surface film is applied to the inner and outer surfaces to prevent corrosion during storage and transportation or during use. However, if welding is performed without removing this surface film or oxides caused by corrosion from the pipes, it will not only reduce the quality of the weld but also cause problems such as unstable arc during welding.

[0004] Reference Figure 1 The existing device for removing internal coatings and impurities from a pipe, disclosed in Korean Patent No. 10-0832836 (grant date: May 21, 2008), includes: a device retaining ring 10 for tightly fixing to the inner surface of the pipe 1; a forward / reverse plunger 20 for operating forward and backward from the device retaining ring; a motor 30 disposed at the center of a fixed body coupled to the forward / reverse plunger; a rotating shaft 40 coupled to the reducer shaft of the motor; a front cutting head 50 for crushing the coating and impurities adhering to the inner surface of the pipe when coupled to the rotating shaft; a front scraper head 60 for scraping the coating and impurities adhering to the inner surface of the pipe when coupled to the rotating shaft; and an air brush for spraying air when coupled to the rotating shaft.

[0005] However, when using existing devices to remove the membrane from the pipe, the amount of membrane cutting cannot be adjusted, and there is a problem that other sizes of devices are needed when the pipe diameter changes. In addition, there is a disadvantage that it can only remove the membrane from one side of the inner or outer surface of the pipe. Summary of the Invention

[0067] The technical concept of the present invention will now be described in more detail with reference to the accompanying drawings. Here, the terms or words used in this specification and the scope of the claims should not be limited to their general or dictionary meanings, but should be interpreted as meanings and concepts consistent with the technical concept of the present invention, based on the principle that the inventors are able to appropriately define the concepts of the terms in order to best describe their invention.

[0068] Therefore, it should be understood that the embodiments described in this specification and the structures shown in the accompanying drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Thus, various modifications that can replace them may be made when this application is filed.

[0069] The technical concept of the present invention will now be described in more detail with reference to the accompanying drawings. The drawings are merely illustrative examples provided to illustrate the technical concept of the present invention in greater detail, and the technical concept of the present invention is not limited to the depiction of the drawings.

[0070] Reference Figure 2The multifunctional pipe membrane removal device 1000 according to the present invention is an apparatus for removing membrane from the inner or outer surface of a pipe P, characterized in that it comprises: a tool part 100 for removing the membrane; a roller part 200 including at least one surface roller 210 traveling on the inner or outer surface of the pipe P; and a connecting part 300, the connecting part 300 comprising: a first plate 310 connected to the tool part 100; and a second plate 320 disposed on the other side of the first plate 310 and connected to the first plate 310 via a shaft, and the second plate 320 connected to the roller part 200.

[0071] The roller 200 travels along the inner or outer surface of the pipe P, and the tool 100 is disposed in front of or behind the roller 200 in the direction of travel, thereby cutting the film on the inner or outer surface of the pipe P as the roller 200 travels.

[0072] The connecting part 300 connects the roller part 200 and the tool part 100, and is connected so that the roller part 200 is in close contact with the inner or outer surface of the pipe P, and the tool part 100 is able to remove the film by being in close contact with the inner or outer surface of the pipe P as the roller part 200 moves.

[0073] The multifunctional pipe membrane removal device 1000 according to the present invention, as described above, has the following effects: it can remove the membrane regardless of the diameter of the pipe P; it is easy to use and manufacture due to its simple structure; and by adjusting the relative position or angle of the tool part 100 and the roller part 200 through the connection part 300 structure, it can remove the outer surface membrane and the inner surface membrane of the pipe P.

[0074] Reference Figure 3 The tool part 100 may include: a main body part 110, the main body part 110 including a rotary motor with a rotating shaft 111 exposed to the outside; and a processing part 120, the outer peripheral surface of the processing part 120 contacting the surface of the pipe P, and one side connected to the rotating shaft 111.

[0075] The rotating shaft 111 rotates via the rotary motor, the processing unit 120 rotates according to the rotation of the rotating shaft 111, and the outer peripheral surface of the processing unit 120 can remove the membrane by contacting the inner or outer surface of the pipe P.

[0076] At this time, the tool part 100 may further include a bearing 130, which is disposed on the other side of the machining part 120 and whose inner diameter is connected to the rotating shaft 111.

[0077] The bearing 130 is coupled to the tool section 100 to rotate together with the rotating shaft 111, and its outer diameter travels together with the surface roller 210 on the inner or outer surface of the pipe P. The bearing 130 can support the machining section 120 on the inner or outer surface of the pipe P, and the other end of the machining section 120 is in contact with the inner or outer surface of the pipe P, thereby maintaining a predetermined machining amount on the pipe P.

[0078] More preferably, the outer diameter of the machining section 120 is larger than the outer diameter of the bearing 130, and a predetermined inclination can be formed with the length direction of the rotating shaft 111 as a reference. Therefore, the maximum depth of cutting of the surface of the pipe P can be determined based on the difference in outer diameters of the machining section 120 and the bearing 130, and the shape of the cutting surface can be inclined rather than parallel based on the predetermined inclination formed by the outer diameter of the machining section 120.

[0079] Furthermore, the tool section 100 can be adjusted in position along the length of the pipe P. That is, the position of the tool section 100 or the processing section 120 itself can be adjusted along the length of the pipe P, thereby adjusting the processing width of the membrane to be removed in the pipe P.

[0080] Additionally, in the tool section 100, at least a portion of the main body 110 is inserted into the insertion hole 311 to connect to the first plate 310. At this time, the position of the tool section 100 can be adjusted by moving the main body 110 along the length direction of the pipe P by tightening or loosening the diameter adjusting bolt 400.

[0081] Reference Figure 4 The roller section 200 may include: a main frame 220 connected to the surface roller 210 and the connecting section 300; and an elastic section 230 connected to the main frame 220 and including: an elastic roller 231 traveling on the outer surface of the pipe P; and a pressurizing section 232 pressurizing the elastic roller 231 onto the outer surface of the pipe P.

[0082] One side of the main frame 220 can be connected to the connecting part 300, and the other side can be connected to the pressurizing part 232. The elastic roller 231 can be pressurized by the pressurizing part 232 to press against the outer or inner surface of the pipe P, thereby traveling in a state of close contact with the outer or inner surface of the pipe P.

[0083] When the surface roller 210 travels on the inner surface of the pipe P, the elastic roller 231, which is set to face each other relative to the surface roller 210, travels in a state of close contact with the outer surface of the pipe P, so that it can actively respond to the deformation of the pipe P.

[0084] At this time, the elastic roller 231 can also be made into a metal collar with a diameter larger than that of the surface roller 210, thereby forming an elastic support for the pressure portion 232. There can be two or more surface rollers 210, and in this case, the elastic roller 231 with a diameter larger than that of the surface roller 210 can be located between two of the surface rollers 210.

[0085] Furthermore, the surface roller 210 and the elastic roller 231 can rotate in a certain direction. That is, the surface roller 210 and the elastic roller 231 can be configured to include a device for fixing the rotation direction in a certain direction, thereby preventing reverse rotation during the film removal process.

[0086] Reference Figure 5 The surface roller 210 may include a rotating shaft that is tilted at a predetermined angle relative to the extension direction of the pipe P, so as to keep the main frame 220 tightly against the end face of the pipe P during rotation.

[0087] That is, the surface roller 210 may have a rotation axis tilted at a predetermined angle with respect to the extension direction of the pipe P, and the rotation axis is tilted so that the main frame 220 is tightly attached to the pipe P as it rotates.

[0088] Reference Figure 6 The elastic roller 231 may include a rotating shaft that is tilted at a predetermined angle relative to the extension direction of the pipe P, so as to keep the main frame 220 tightly against the end face of the pipe P during rotation.

[0089] That is, the elastic roller 231 may have a rotating shaft tilted at a predetermined angle with respect to the extension direction of the pipe P, and the rotating shaft is tilted so that the main frame 220 can be tightly attached to the pipe P as it rotates.

[0090] Reference Figures 4 to 6 The roller section 200 may further include a guide roller 240, which is connected to the main frame 220 and is formed in at least one direction in front of and behind the surface roller 210 in the direction of travel, and travels on the surface at the end of the extension direction of the pipe P.

[0091] The guide roller 240 reduces the friction generated between the end face of the pipe P and the main frame 220 when the surface roller 210 or the elastic roller 231 travels, so that the main frame 220 can travel smoothly in a state of close contact with the end of the pipe P.

[0092] Additionally, refer to Figure 7 The second plate 320 may include a pipe diameter adjustment track 323, which is formed by extending from one side to the other through a predetermined angle region. Furthermore, the connecting portion 300 may further include a pipe diameter adjustment fastening component 440, which is simultaneously fastened to both the pipe diameter adjustment track 323 and the roller portion 200.

[0093] The pipe diameter adjustment track 323 is a structure for adjusting and fixing the positions of the roller section 200 and the tool section 100. More specifically, by adjusting the positions of the processing section 120 and the surface roller 210 according to the diameter of the pipe P, the processing section 120 and the surface roller 210 can remain in close contact with the surface of the pipe P regardless of the diameter of the pipe P.

[0094] Reference Figures 7 to 8 The first plate 310 and the second plate 320 have a specified thickness, one side of the first plate 310 is exposed to the outside, and the other side of the first plate 310 overlaps with one side of the second plate 320, thereby forming the connecting portion 300.

[0095] Reference Figures 8 to 11 The first plate 310 and the second plate 320 rotate relative to each other with respect to the plate connecting shaft 301 that passes through and connects the shaft connecting holes 316 and 325 respectively formed in the first plate 310 and the second plate 320.

[0096] Reference Figures 8 to 9 The first plate 310 may include: an insertion hole 311 that extends from one side to the other to allow the tool portion 100 to be inserted; and a cut through space 312 that allows adjustment of the diameter of the insertion hole 311 and application of pressure. Furthermore, the connecting portion 300 may further include a diameter adjusting bolt 400 that extends transversely through the through space 312 from the outer side of the first plate 310 and is fastened to the inner side of the first plate 310.

[0097] The tool part 100 can be adjusted along the length of the pipe P through the through space 312, and tool parts 100 of various diameters can be installed in the insertion hole 311. The diameter adjusting bolt 400 is fastened to the first plate 310 when the tool part 100 is inserted into the insertion hole 311, thereby fixing the position of the tool part 100 on the first plate 310 without changing it.

[0098] Reference Figures 9 to 11 The first plate 310 may further include a first fastening hole 313, which extends from one side of the first plate 310 to the other side. The second plate 320 may include second fastening holes 321 and 321b, which communicate with the first fastening hole 313 on the outer side 321a of the second plate 320. Furthermore, the connecting portion 300 may include: a first fastening member 410, which is inserted into the first fastening hole 313; and a first spring 422, which is inserted into the second fastening hole 321 and whose end contacts the other end of the first fastening member 410.

[0099] At this time, the second fastening component 420 may include: a first spring 422 inserted into the second fastening hole 321; and an adjusting bolt 421 mounted on the outer side 321a of the second plate 320 to adjust the elastic force of the first spring 422. The first spring 422 is preferably configured as a compression spring.

[0100] When the first fastening member 410 is fastened from one side of the first plate 310 to the other, the other end of the first fastening member 410 contacts the end of the first spring 422. At this time, when the first spring 422 presses the first fastening member 410, the processed part 120 mounted on the first plate 310 is elastically supported in the direction of the inner or outer surface of the pipe P in contact with it, thereby being pressurized against the inner or outer surface of the pipe P.

[0101] The amount of material removed from the membrane is determined based on the difference in outer diameter between the processing section 120 and the bearing 130 located at the end of the processing section 120. In this case, the processing section 120 maintains the predetermined amount of material removed even if the pipe P deforms (deviates from a perfect circle) or its thickness changes (outer and inner diameters) due to the adjusted elastic force of the first spring 422 pressing the first fastening member 410.

[0102] When the support direction of the first spring 422 of the first fastening member 410 is changed from the inner diameter to the outer diameter or from the outer diameter to the inner diameter as required, the present invention can be changed to a device for processing the outer diameter or a device for processing the inner diameter.

[0103] The adjusting bolt 421 is fastened to the second plate 320, and the elastic force of the first spring 422 can be adjusted according to the fastening depth of the second plate 320. As the fastening depth of the adjusting bolt 421 increases, the elastic force of the compressed first spring 422 increases, thereby increasing the adhesion between the pipe P and the tool part 100 (or the processing part 120).

[0104] Reference Figure 12 The first plate 310 may further include a third fastening hole 314, which extends from one side of the first plate 310 to the other. Furthermore, the second plate 320 may further include a bushing groove 322, which extends from one side of the second plate 320 to the other and communicates with the third fastening hole 314. Additionally, the connecting portion 300 may further include a third fastening member 430, which is fastened to the third fastening hole 314.

[0105] The third fastening component 430 is kept in the state of being screwed into the third fastening hole 314, and can be partially inserted into or not inserted into the bushing groove 322 depending on the screw fastening depth.

[0106] At this time, the diameter of a designated area on one side of the bushing groove 322 can gradually widen towards one end, and the diameter of a designated area on the other side of the third fastening member 430 can gradually decrease towards the other end. Furthermore, the third fastening member 430 may further include a second spring 431, which is fixed to the first plate 310 and wraps around the outer peripheral surface of one side of the third fastening member 430.

[0107] The second spring 431 is a structure for elastically supporting the third fastening component 430 to prevent the third fastening component 430 from loosening and changing position due to vibration or other reasons during operation.

[0108] Reference Figures 13 to 15The displacement c, resulting from the engagement of the pipe diameter adjusting fastening member 440 with the roller section 200 and the pipe diameter adjusting track 323, is used to accommodate changes in the diameter of the pipe P. Furthermore, the third fastening member 430 and the third fastening hole 314 can adjust for changes in the position of the machining section 120. And the displacement d, generated based on the degree of engagement between the third fastening member 430 and the bushing groove 322, is used to adjust the cutting displacement of the tool section 100.

[0109] By fixing the surface roller 210 and the elastic roller 231 to one side of the pipe P, and adjusting the pipe diameter adjustment track 323 to correspond to the pipe P specification (diameter), the displacement c can be adjusted. Furthermore, when the processing part 120 is rotated while the third fastening member 430 is gradually inserted into or pulled out of the bushing groove 322, the processing part 120 moves relative to the connecting shaft 301, corresponding to a displacement d. At this time, the first fastening member 410 presses the first spring 422, which can press the processing part 120 against the inner or outer surface of the pipe P.

[0110] Reference Figure 14 and Figure 15 The positions of the second fastening hole 321 and the stroke limiting groove 315 can be different from the pressing direction of the first spring 422. That is, when removing the inner diameter membrane of the pipe P, the above structure can be configured to cause the processing part 120 to press the inner diameter of the pipe P. Conversely, when removing the outer diameter membrane of the pipe P, the above structure can be configured to cause the processing part 120 to press the outer diameter of the pipe P.

[0111] Reference Figure 16 The second plate 320 may further include a travel limiting protrusion 324 protruding on one side, and the first plate 310 may further include a travel limiting groove 315 formed on the other side to accommodate the travel limiting protrusion 324, the travel limiting groove 315 being able to change its relative position with respect to the travel limiting protrusion 324.

[0112] The travel limiting groove 315 and the travel limiting protrusion 324 are structures designed to maintain the insertion position and prevent displacement from the specified area when the third fastening member 430 is completely disengaged from the third fastening hole 314.

[0113] Reference Figure 17 The surface roller 210 and the elastic roller 231 can be configured to face each other while in contact with the outer surface of the pipe P, respectively.

[0114] That is, when the diameter of the pipe P is small, rotating the surface roller 210 on the outer surface can achieve more stable film cutting than rotating it on the inner surface of the pipe P. In this case, the surface roller 210 and the elastic roller 231 are configured to apply pressure and travel on the pipe P in a direction facing each other with the pipe P as a reference, thereby allowing the roller portion 200 to be more stably mounted on the pipe P.

[0115] like Figure 17 As shown, in order to allow the first plate 310 and the second plate 320 to rotate relative to each other according to the specifications of the pipe P, the first plate 310 and the second plate 320 can be connected to a bracket separately formed on the main frame 220 via the connecting shaft 301.

[0116] Reference Figures 17 to 18 The position of the surface roller 210 coupled to the roller portion 200 can be changed. That is, in order to remove the film from the relatively smaller pipe P, the pipe P can be positioned between the elastic roller 231 and the surface roller 210 by changing the coupling position of the surface roller 210. The surface roller 210 can be coupled in a plurality of roller mounting holes 211 spaced at predetermined intervals along the extending direction of the main frame 220, and the coupling position can be changed according to the diameter of the pipe P.
