Description

A pipe identification device identifiable from the outside, a pipe selection method, and a pipe demolition method using the same to prevent accidents of incorrect cutting

[0001] The present invention relates to a device for identifying a demolition pipe that can be identified from the outside and a method for demolishing a pipe using the same for preventing an accidental cutting of a pipe. More specifically, the present invention relates to a device for identifying a pipe to be demolished and a method for demolishing a pipe, which can easily identify a pipe to be demolished from the outside when demolishing a specific pipe according to the purpose in a pipeline system that supplies various types of fluids, and which can prevent an accidental cutting of a pipe.

[0002]

[0003] Fluids used in typical semiconductor and display manufacturing processes, as well as in various other manufacturing processes, are supplied in a variety of forms, depending on the intended use of the product being manufactured. Even water (H2O), a common liquid, can cause significant production problems if not supplied to the process. Furthermore, gases can also contain hazardous gases, which are highly toxic to the human body and can cause safety accidents if even a small leak occurs. The pipeline systems that supply fluids used in semiconductor and display manufacturing processes can have different piping configurations depending on the type of fluid used, the amount of fluid used, and the location of the supply. This creates countless pipelines that supply each piece of equipment.

[0004] Furthermore, pipeline systems can change frequently depending on the purpose of use, such as equipment movement or equipment changes, and the type or location of the fluid supplied can change frequently. Consequently, there are frequent instances where specific pipes must be demolished. In such cases, when removing pipes containing hazardous gases or fluids in use, gas leaks can cause significant casualties or property damage. Therefore, when demolishing, the pipes must be classified by type and purpose of use and handled in strict accordance with demolition manuals. In particular, it is crucial to thoroughly identify the pipes to be demolished, and even these identified pipes must be reconfirmed. In complex work situations, it is crucial to repeatedly confirm that the target pipe is the correct one before cutting, thereby preventing accidents due to incorrect cutting.

[0005] Conventional pipeline systems typically involve countless pipes, and as they are installed over a long period of time, they become increasingly complex, resulting in irregular lengths and shapes within each pipe. This posed a challenge in ensuring all pipes were distinguishable, and the task of selecting pipes for demolition in these complex work environments became particularly challenging. Furthermore, because pipes can pass through various walls and air ducts, the process of selecting pipes for demolition within the line became challenging. This led to problems such as double-checking selected pipes, or even if accurately selected, miscutting during demolition.

[0006] Because even a small gas leak due to a single mistake can cause fatal accidents to the human body, a method is needed to prevent any errors in the demolition method at its source.

[0007]

[0008] The present invention has been made to solve the above problems, and the purpose of the present invention is to provide a pipe selection device and a pipe demolition method that can easily distinguish pipes to be cut from the outside so that the pipes can be easily and accurately selected during demolition work, minimize the repetitive selection process, and solve the problems of human error or waste of manpower, and perform external identification and data identification of the pipes together to completely identify the pipes to be demolished before performing the work, thereby fundamentally preventing accidents of incorrect cutting of the pipes.

[0009] In addition, the pipe to be cut can be easily identified from the outside, so that the pipe can be easily and quickly selected during the demolition work, and since the work can be repeated even for long pipes, it can provide convenience in the pipe selection work, and by using this, the demolition work of cutting the pipe to be demolished can be performed, so that the accuracy of the pipe demolition work can be improved, and also, the demolition pipe identification device that can provide convenience in the work process of inserting a magnetic core into the pipe to be demolished is provided.

[0010]

[0012] At this time, in step B), if the pipe to be demolished is identified, step B-1) is further performed, in which the corresponding pipe information is stored in the magnetic measuring device, the information is generated as a barcode, printed as a sticker, and the sticker is attached to the pipe to be demolished.

[0016] In addition, the magnetometer is characterized by including a probe that measures the magnetic force of the magnetic core from the outside of the pipe, and a first processor that stores and manages the magnetic force measured by the probe and information about the pipe as data, and generates the data as a barcode.

[0017] In addition, in the step a), if the magnetic force detected by the cutter is invalid, the pipe to be demolished is identified using a magnetic force measuring device outside the pipe.

[0018] At this time, in the step a), the magnetic sensor is characterized in that if the sensed magnetic value is below a certain level, the power of the cutting unit is kept off.

[0020] At this time, in step a-0), if the barcode information recognized by the scanner and the information on the pipe to be demolished are valid, step a) is performed, and if the barcode information recognized by the scanner and the information on the pipe to be demolished are not valid, a step of re-selecting the pipe to be demolished externally is performed.

[0021] In addition, the cutter is characterized by further including a scanner that scans a barcode, a second processor that stores and manages the magnetic force measured by the magnetic sensor and the information of the barcode scanned by the scanner as data, and compares and determines the received information.

[0037]

[0062]

[0063] The present invention provides a pipe demolition process that can safely and easily perform the pipe demolition process while fundamentally preventing errors that may occur during the demolition process. A pipeline system comprises a plurality of pipes (tubes) (10) arranged in a manner that not only extends to different lengths, but also extends to different locations or intersects with one another, and may be installed while passing through various walls and ventilation ducts. Therefore, conventionally, pipes to be demolished were repeatedly checked and the checked lines were rechecked to select the pipes to be demolished. However, the present invention replaces this process with a process of selecting the pipes (10) by inserting a magnetic core (100) into the demolition pipe (11), thereby eliminating the need for separate demolition line selection and double selection, thereby shortening the demolition time and process, reducing labor costs, and enhancing the safety of the demolition process. The present invention is characterized by including a pipe selection device that is identifiable from the outside, and a pipe demolition method that prevents accidents caused by incorrect cutting using the same.

[0064]

[0065] As illustrated in FIG. 1, the present invention is characterized in that a pipe demolition process can be performed by inserting a magnet core (100) into a pipe (11) to be demolished among a plurality of pipes (10), measuring the magnetic force of the inserted magnet core (100) from the outside of the pipe (11) using a magnetic force measuring device (200) to identify the inserted magnet core (100), and when the target pipe (11) is identified after the cutter (300) that cuts the pipe (11) measures the magnetic force before cutting, the cutter (300) cuts the pipe (11). Accordingly, referring to FIG. 2, the pipe selection device of the present invention is characterized in that it comprises a cutter (300) that includes a magnetic core (100) inserted into the pipe (11), a magnetic force measuring device (200) that measures the magnetic force from the outside of the pipe (11), a cutting unit (310) that cuts the pipe (11), and a magnetic force sensor (320) that measures the magnetic force.

[0066] The magnet core (100) of the present invention is characterized by including a magnet portion (120) that is inserted only into a pipe (11) to be demolished and generates magnetic force. In addition, the magnet core (100) of the present invention is characterized by including a central portion (110) whose length is formed at least according to the length of the pipe (11) to be demolished, and a plurality of magnet portions (120) having a predetermined length and coupled to the outer diameter of the central portion (110).

[0067] Referring to FIGS. 3 to 5, the center (110) can pull the magnet core (100) while it is inserted and installed inside the pipe, and is inserted inside along the pipe (11) to be demolished with the magnet part (120) coupled to the outer diameter. Accordingly, it is preferable that it be formed with a sufficient length so that it can be inserted into the entire pipe (11) to be demolished. The center (110) can be formed without restrictions on shape or material as long as it can form a length, and if there is a separate feeder for inserting the magnet core (100) into the pipe, the center (110) can be formed with a flexible material, or if there is no separate feeder, the center (110) can be formed with a rigid material to pull the magnet part (120). That is, if the guide line is formed integrally, the center (110) can be made of steel or steel wire, or if there is a separate feeder, the center (110) can be made of a soft material. The central portion (110) may be formed of a fine diameter such as a line, may have a constant diameter, and when formed with a constant diameter, it is preferable to form it with a diameter smaller than the diameter of the magnet portion (120). In one embodiment of the present invention, the central portion (110) may be formed of steel wire, piano steel wire, nylon string, or the like.

[0068] Referring to FIGS. 3 to 5, the magnet portion (120) is coupled to the outer diameter of the central portion (110), and is characterized in that a plurality of magnet portions (120) are provided on the central portion (110) while being spaced apart from each other. The magnet portions (120) are characterized in that they have a predetermined length, and are arranged while being spaced apart from each other on the central portion (110) at predetermined intervals. The magnet portions (120) may have a cylindrical or polygonal outer shape, and may be formed without limitation as long as they can be arranged in a state where they can be easily moved within a pipe. At this time, the length of the magnet portions (120) and the length of the distance between the magnet portions (120) may be selected according to necessity, according to the work situation, or in consideration of the material of the central portion (110). However, it is preferable to secure a sufficient distance between the magnet portions (120) to prevent the magnet portions (120) from sticking to each other.

[0069] In order to prevent the phenomenon of magnets (120) sticking together, if necessary, as illustrated in FIG. 5, the magnets (120) may further include a spacer (130) between the magnets (120) in order to maintain a distance apart from the center (110). The spacer (130) is for fixing a constant distance apart from the magnets (120) that are arranged adjacent to each other, and may be formed of a soft plastic tube. Through the spacer (130), the phenomenon of magnets sticking together can be prevented, and a sufficient distance apart from each other can be secured.

[0070] The magnet part (120) may be used without limitation as long as it is a magnetic material that generates magnetic force. At this time, it is preferable that the magnet part (120) be formed with a diameter smaller than the diameter of the pipe so that it can be easily inserted and guided along the center (110) within the pipe. Since the magnet part (120) must be able to detect a magnetic force of a certain strength or higher from the outside of the pipe, it is preferable that the magnet part (120) be formed with a magnetic material that generates a magnetic force of a certain strength or higher. At this time, if the material of the magnet part (120) has a weaker magnetic force, it is preferable to form it with a large diameter so that it can generate a magnetic force of a certain strength or higher. In addition, if the material of the magnet part (120) has a strong magnetic force, it can be formed with a smaller diameter. In one embodiment of the present invention, the magnet part (120) may be a neodymium magnet.

[0071] And, the magnet part (120) of the present invention may be configured with polarity divided into each N pole and S pole. That is, the magnet part (120) of the present invention may generate magnetic force by the spin of the atomic nucleus. Therefore, the magnet part (120) may be configured with a form in which the N pole part and the S pole part are divided. At this time, as illustrated in FIG. 3, the magnet part (120) may be in a form (121) in which the N pole and the S pole are arranged horizontally to each other along the longitudinal direction of the center (110). That is, the magnet part may be a horizontal type (Example 1) in which the N pole and the S pole are arranged horizontally. The horizontal type magnet part (121) has the advantage of being easy to arrange the polarities when arranging a plurality of magnet parts in the center (110), and can be easily arranged while maintaining the spacing between them more accurately. In addition, as illustrated in FIGS. 4 and 5, the magnet portion may be in a form in which the N pole and the S pole are arranged perpendicular to each other in a direction perpendicular to the longitudinal direction of the center portion (110) (Example 2). That is, the magnet portion (121) may be a vertical type (122) in which the N pole and the S pole are arranged vertically. Although the vertical magnet portion (122) may have difficulty in arranging the exact polarity when arranging a plurality of magnet portions in the center portion (110), after arranging a plurality of magnet portions in the center portion (110), when there is a certain distance from the magnet portion (122), the detection amount of magnetic force is higher than that of the magnet portion of the same area, which has the advantage of making it easy to detect magnetic force from the outside of the pipe. In addition, as illustrated in FIG. 5, the vertical magnet portion (120) may be arranged so that the polarities of the adjacent magnet portions are alternately positioned differently along the length of the center portion (110) (Example 3).That is, when the above-described formula-type magnet part (120) is arranged in parallel with a plurality of magnet parts in the center (110), the magnet part with the N pole positioned upward can have the S pole positioned upward in the adjacent magnet part along the length based on the magnet part, and further, the neighboring magnet part (120) can have the N pole positioned upward, and the polarities at the top can be alternately arranged as the N pole and the S pole. Accordingly, the arrangement of the magnet parts in the center (110) can be performed more easily while improving the detection amount of magnetic force.

[0072] At this time, the present invention may include a feeder for inserting the magnet core (100) into the pipe (11). The feeder may be formed in the form of a gear wheel that is coupled to one end of the center (110) which is the induction line (101), and may be configured such that the connected induction line (101) moves as the gear wheel moves inside the pipe, thereby pulling and inserting the magnet core (100) into the pipe (11). At this time, referring to Fig. 6, the feeder may be a wire feeder, and the wire feeder may be used when the induction line is a steel wire. The wire feeder is characterized in that it pulls the magnet core into the pipe by inserting the induction line into the pipe, connecting the end of the inserted induction line and the end of the magnet core, and pulling out the induction line. The above wire feeder can be speed controlled through an operating unit that inserts the induction line (101) into the pipe, and may include a function of moving the induction line (101) forward and inserting it, or moving the induction line (101) backward and pulling it.

[0073] In addition, referring to Fig. 7, the feeder can be formed in a launch type, and at this time, the guide line can be made of nylon. The feeder in the launch type has a pig ball made of an elastic material formed with a diameter corresponding to the inner diameter of the pipe (11), and an induction line (101) connected to a magnet core (100) at the rear end of the pig ball, and the pig ball can be first inserted into one end of the pipe (11). Then, when a pig ball launcher that supplies a compressed fluid into the pipe (11) supplies a compressed fluid such as air or nitrogen from one end of the pipe (11), the pig ball moves in the other direction, and thus the induction line (101) moves along the movement direction of the pig ball, and the magnet core (100) connected to the induction line (101) can be inserted into the pipe (11). In addition, the feeder can be formed in various ways without limitation as long as it can insert the magnet core (100) into the pipe (11).

[0074] The magnetic force measuring device (200) of the present invention is a device that measures magnetic force using a probe (210) outside a pipe (11). The magnetic force measuring device (200) is intended to detect the magnetic force of a magnet core (100) inserted inside a pipe (11) to be demolished, and if a magnetic force greater than a certain standard magnetic force is detected outside the pipe based on the magnetic force formed by the magnet core (100), the pipe can be identified as a pipe (11) to be demolished. The magnetic force measuring device (200) can be used without limitation as long as it can measure magnetic force, can be configured as a Gaussian measuring device, and can be formed to be portable.

[0075] Referring to FIG. 2, the magnetic force measuring device (200) may include a probe (210) that measures the magnetic force of the magnet core (100), and a first processor that stores and manages information such as the magnetic force measured by the probe (210) and information about the pipe by converting the information into data. The first processor may analyze and determine that the magnetic force measured by the probe (210) for a pipe is the magnetic force for the pipe (11) to be demolished into which the magnet core (100) is inserted, and display the data so that a worker can identify whether the pipe is the pipe (11) to be demolished. In other words, the magnetic force measuring device (200) is a device that can identify from the outside which pipe among a plurality of pipes (10) is the pipe (11) to be demolished. And, the first processor can store and manage information about the pipe whose magnetic force has been measured as data, and can dataize information about the measured magnetic force, information about the corresponding pipe, and information about the pipe (11) to be demolished that has been included, and can transmit and receive signals with an external device. In addition, the first processor can select specific information about a certain pipe and generate a barcode so that the selected information can be easily read from the outside. For example, when the magnetic force measuring device (200) measures the magnetic force from the outside of the pipe using a probe (210) for a pipe that is expected to be a pipe to be demolished, the first processor receives the magnetic force value, compares and determines with the magnetic force of the previously input reference magnetic core (100), and determines whether the pipe is a pipe (11) to be demolished with the magnetic core (100) inserted. At this time, the first processor can group and store the selection record separately together with the information about the corresponding pipe, and can generate a barcode for this information. The barcode generated by the first processor can be printed in the form of a sticker through a barcode printer, so that the sticker can be identifiably attached to the outside of the pipe.The above barcode printer may be configured as an integral part of a magnetometer (200), or may be connected with a wire or wireless connection.

[0076] Referring to FIG. 2, the cutter (300) of the present invention is a device for cutting a pipe (11) to be demolished. In addition, the cutter (300) may include a cutting unit (310) arranged at one end to cut the pipe, and a magnetic sensor (320) for measuring magnetic force. The cutting unit (310) is configured to directly cut the pipe, and can be formed without limitation as a rechargeable, hydraulic, or electric type as long as it is configured as a means for cutting the pipe regardless of the type and material of the pipe. In addition, the cutter (300) is characterized in that the cutting unit (310) and the magnetic sensor (320) are configured as an integral part. The magnetic sensor (320) is characterized in that it is a sensor capable of measuring the magnetic force of the magnetic core (100) from the outside of the pipe, such as a probe (210) of a magnetic force measuring device (200). The magnetic sensor (320) is provided to finally confirm whether the identified pipe is a pipe (11) to be demolished before performing a cutting operation using the cutter (300) on the identified pipe. That is, the magnetic sensor (320) can measure the magnetic force of the magnetic core (100) inserted inside the pipe (11) to be demolished. At this time, the magnetic sensor (320) may be the same as or a different magnetic force measuring device than the probe (210) of the magnetic force measuring device (200). The magnetic sensor (320) may be provided without location restrictions within the cutter (300) as long as it is located at a position where it can measure the magnetic force at a certain clearance distance from the pipe, and may be arranged on the cutting section (310) side or at any edge portion of the cutter (300).

[0077] The cutting machine (300) of the present invention is characterized in that a separate power source is formed for the operation of the cutting unit (310). That is, the cutting machine (300) has its own power source, and the cutting unit (310) also has power source, so that the operation of cutting the pipe can be turned on / off. At this time, the cutting unit (310) includes a second processor, and the second processor can turn the power of the cutting unit (310) on / off. The second processor can store and manage the magnetic information measured by the magnetic sensor (320) by converting it into data, and compare and determine the received information. The second processor is characterized in that it turns the power of the cutting unit (310) on or off based on the magnetic information received from the magnetic sensor (320). That is, if the magnetic force measured by the magnetic sensor (320) is greater than a certain value, the second processor can turn on the power of the cutting unit (310) to allow the cutting unit (310) to cut the pipe. Conversely, if the magnetic force measured by the magnetic sensor (320) is less than a certain value, the second processor can keep the power of the cutting unit (310) off and limit the cutting of the pipe by the cutter.

[0078] In addition, the cutter (300) may further include a scanner that scans a barcode. The scanner may be integrated with the cutter (300) or may be connected wired or wirelessly. This means that when a pipe (11) to be demolished is identified by a magnetic force measuring device (200), a barcode containing information about the pipe is generated and attached to the outside of the pipe in the form of a sticker, before the cutter (300) cuts the pipe, the scanner can be used to scan the barcode to easily confirm that the pipe is the pipe (11) to be demolished. At this time, the scanner transmits and receives information with the second processor, and when the second processor determines that the information of the barcode scanned by the scanner is the pipe (11) to be demolished, the cutter (300) can be turned on. The second processor can convert the information received through the scanner into data and store and manage it, and can manage it together with the magnetic force measured by the magnetic force sensor (320).

[0079] The fluid supply and recovery system may be composed of countless pipes (10) intertwined to form different flow paths, and may be arranged to pass through various walls and ventilation ducts depending on the structure of the factory. In addition, the fluid supplied by the pipes (10) may be toxic to the human body or a hazardous gas that may cause facility accidents. At this time, specific pipes (11) may be demolished depending on the purpose. Since partial demolition of the pipes in the supply system is an essential process when changing, replacing, or moving production equipment, the pipe demolition work is generally performed by cutting the pipes at regular intervals according to their lengths. Therefore, in order to safely perform the demolition work, it is very important to accurately identify the pipes (11) selected as the target for demolition. However, since the pipes (10) provided in the fluid supply and recovery system are difficult to distinguish by appearance, it takes a lot of time to identify and distinguish the pipes (11) to be demolished, and since workers must check them one by one, unnecessary manpower is invested and the risk of the work increases.

[0080] The present invention is intended to solve this problem, and includes a method for selecting pipes that are identifiable from the outside using a pipe selection device that is identifiable from the outside. At this time, the pipe selection device may be composed of a magnetic core (100), a magnetic force measuring device (200), and a cutter (300) having the above-described features. Accordingly, referring to FIG. 8, the pipe selection method of the present invention is characterized by including a step A) of separating the front and rear ends of a pipe to be demolished and inserting a magnetic core into the inside of the pipe to be demolished; and a step B) of measuring the magnetic force of the pipe from the outside using a magnetic force measuring device that detects magnetic force to identify the pipe to be demolished.

[0081] More specifically, the above pipe selection method can determine whether to demolish a pipe depending on the purpose of the fluid supply and recovery system, and when the demolition of a specific pipe is determined, the pipe is classified as a pipe (11) to be demolished, and a demolition method for the pipe (11) can be reviewed to establish a demolition plan including the work period and work method. In addition, during the demolition work, the front and rear ends of the pipe (11) to be demolished are already known, and work can be performed to exhaust any fluid that may remain inside the pipe (11) before the full-scale demolition work. At this time, the residual fluid inside the pipe (11) can be confirmed by putting a harmless fluid into one end of the pipe (11) and detecting a harmful substance at the other end.

[0082] If it is confirmed that the interior of the pipe (11) to be demolished has been cleaned, the front and rear ends of the pipe (11) can be separated and prepared. Then, the type of magnet core (100) can be selected according to the demolition plan or the on-site situation. At this time, the type of magnet core (100) can be determined by the induction method depending on the type of feeder, or can be selected in consideration of the length of the pipe, the diameter of the pipe, etc. The magnet core (100) can be selected by combining the type of the center (110), the arrangement type of the magnet portion (120) (vertical, horizontal), the presence or absence of a spaced portion (130), the presence or absence of an induction line (101), etc.

[0083] And, referring to FIG. 7, step A) can be performed by inserting the magnet core (100) into the inside of the pipe (11) to be demolished according to the selected magnet core (100) and the induction method. The detailed insertion method of step A) can be selected in various ways depending on the types of feeder, magnet core (100), induction line (101), etc., such as inserting by pulling the magnet core (100) after guiding the steel wire, or by using a pigball launch method. More specifically, in step A), the magnet core can be inserted by connecting an induction line to one end of the magnet core, and a wire feeder inserting the induction line into the pipe to be demolished and pulling the magnet core. Alternatively, in the step A), the magnet core may be inserted into the pipe using a feeder of a launch type, and the pig ball may be connected to the induction line of the magnet core to supply compressed fluid into the pipe, and the induction line connected to the pig ball may pull the magnet core. At this time, the magnet core (100) inserted into the pipe (11) is preferably inserted entirely from one end of the pipe (11) to be cut to the other end. Alternatively, in the case where the length of the pipe (11) to be cut is so long that it is difficult to insert the magnet core, the demolition may be carried out by inserting the magnet core to an appropriate length and then demolishing it, and then inserting the magnet core at the last part where demolition has been completed, and repeating the demolition process.

[0084] And, referring to FIG. 7, step B) of measuring the magnetic force of the pipe expected to be the target of demolition from the outside of the pipe can be performed using a magnetic force measuring device (200). At this time, in step A), the outside of the pipe (11) into which the magnetic core (100) is inserted can be marked, and step B) can be performed on the marked pipe based on this. In step B), the magnetic force is measured at the outer diameter of the pipe using the probe (210) of the magnetic force measuring device (200), and the pipe (11) to be demolished can be identified by the first processor analyzing whether the measured magnetic force corresponds to the magnetic force of the magnetic core inserted into the pipe (11) to be demolished. At this time, the first processor includes information on a certain standard range of the magnetic force value of the magnetic core (100), and if the magnetic force value received from the probe (210) is within the standard range, it can be determined that the pipe is the target of demolition (11).

[0085] At this time, referring to FIG. 8, if it is identified by confirming that it is the pipe (11) to be demolished, the magnetic force measuring device (200) can store the information of the pipe through the first processor, generate a barcode together with the measured magnetic force information, and output the barcode in the form of a sticker through the printer. Then, the worker can perform step B-1) of attaching the sticker to the outside of the pipe (11) to be demolished. Through step B-1), the pipe (11) to be worked on is marked so that it can be identified from the outside, and at the same time, there is an advantage in that the worker can easily check the work information at the work location by scanning the barcode.

[0086]

[0087] The present invention includes a pipe demolition method that prevents erroneous cutting accidents by using a pipe selection device that is identifiable from the outside. At this time, the pipe demolition method can be performed on a pipe selected through the pipe selection method. That is, after identifying a pipe to be demolished from the outside of the pipe using the magnetic force measuring device of the present invention, the pipe demolition method can be performed on the corresponding pipe. Accordingly, the pipe demolition method of the present invention can be performed including step a) of detecting the magnetic force of the pipe (11) to be demolished by using a magnetic force sensor (320) that senses the magnetic force provided in a cutting device (300) that cuts the pipe to be demolished and confirming the pipe (11) to be demolished, step b) of turning on the power of a cutting unit (310) that cuts the pipe (11) in the cutting device (300) if the magnetic force detected by the cutting device (300) is valid, and step c) of cutting the pipe (11) to be demolished by the cutting unit (310).

[0088] Referring to Fig. 10, if a pipe (11) to be demolished is identified through a magnetic force measuring device (200), step a) of checking information about the pipe can be performed using a cutter (300) for cutting the pipe. Step a) is a step of checking whether the pipe to be worked on is the pipe (11) to be demolished before the cutter (300) cuts the pipe. At this time, the cutting unit (310) of the cutter (300) is turned off. Step a) is characterized in that the magnetic force of the pipe is detected using a magnetic force sensor (320) provided in the cutter (300) and measuring magnetic force, and the second processor receives this and determines whether the magnetic force measured by the magnetic force sensor (320) matches the magnetic force information of the magnetic core (100) inserted into the pipe (11) to be demolished. The second processor may include information within a certain standard range regarding the magnetic value of the magnet core (100) inserted into the pipe (11), and if the magnetic value received from the magnetic sensor (320) is within the standard range, it may be confirmed that the pipe is the pipe (11) to be demolished. In addition, the second processor may compare and determine the magnetic value measured by the magnetic sensor (320) of the cutter (300) with the magnetic value measured by the probe (210) of the magnetic force measuring device (200). That is, the second processor confirms that the pipe in which the cutter (300) is located is the pipe (11) to be demolished if the magnetic value detected by the cutter (300) and the magnetic value detected by the magnetic force measuring device (200) are valid. At this time, the magnetic value being valid means that the magnetic value detected by the magnetic force measuring device (200) is above a certain level, that is, the sensed magnetic value is a value greater than the reference magnetic value.

[0089] At this time, before step a), step a-0) may be performed to check the information of the corresponding pipe by recognizing the barcode attached to the outside of the pipe with a scanner in step a). At this time, the barcode may include information on the demolition work of the corresponding pipe, and after the worker easily checks it, step a) may be performed to check the pipe to be demolished with a cutter. By scanning the barcode of step a-0), the demolition work can be accurately performed according to the work plan included in the barcode. At this time, if the barcode information recognized by the scanner in step a-0) matches the information on the pipe (11) to be demolished, the information on the corresponding pipe is determined to be valid, and step a) may be performed. Alternatively, if the barcode information recognized by the scanner in step a-0) matches the information on the pipe (11) to be demolished, the information on the corresponding pipe is determined to be invalid, and the process may return to the step of externally identifying the pipe to be demolished among the plurality of pipes, which may be the pipe identification step of the present invention. That is, if it is determined through the barcode in step a-0) above that the pipe is not a pipe to be demolished (11), step A) of the pipe identification step can be performed.

[0090] In step a), if the magnetic force detected by the cutter (300) is valid with the magnetic force of the pipe (11) to be demolished, the second processor may perform step b) of turning on the power of the cutting unit (310). That is, if the second processor confirms that the pipe where the cutter (300) is located is the pipe (11) to be demolished, the second processor may turn on the power of the cutting unit (310) to complete preparation for the demolition work. This may be that the second processor turns on the power of the cutting unit (310) when the magnetic force value received by the second processor from the magnetic force sensor is equal to or higher than a certain level.

[0091] In addition, in the step a), if the magnetic force detected by the cutter (300) does not match the magnetic force of the pipe (11) to be demolished, the second processor can keep the power of the cutting unit (310) turned off. At this time, if the magnetic force detected by the cutter is invalid, the pipe to be demolished can be identified using a magnetic force measuring device outside the pipe. That is, in the step a), if the magnetic force value received by the second processor from the magnetic force sensor is below a certain level and the magnetic force is invalid, the power of the cutting unit (310) can be kept turned off. Then, by performing the pipe selection method again, the pipe to be demolished can be re-identified from the outside of the pipe through the pipe selection device. At this time, the process can return to the step of externally identifying the pipe to be demolished among the plurality of pipes, which may be step A) of the pipe identification step of the present invention. That is, if the second processor confirms that the pipe where the cutter (300) is positioned to be cut is not the pipe (11) to be demolished, the method for identifying the pipe again is performed, and the pipe (11) to be demolished can be identified again through the magnetic measuring device (200).

[0092] Thereafter, referring to FIG. 9, when the pipe to be demolished is confirmed by the cutter, the power to the cutting unit can be turned on by performing step b). Accordingly, when it is finally confirmed through the cutter (300) that the pipe where the cutter (300) is located is the pipe to be demolished (11), the power to the cutting unit (310) is turned on, so that preparations for cutting the pipe can be completed through the cutting unit (310).

[0093] And, the cutting unit (310) that is turned on can perform step c) of cutting the pipe (11) to be demolished. When the cutting machine (300) finally confirms the pipe (11) to be demolished, the pipe demolition work can be performed by cutting the pipe according to the demolition plan using the cutting unit (310). At this time, the cutting unit (310) can simultaneously cut the pipe and the magnet core (100) inserted inside the pipe. In addition, the cutting unit (310) can cut the pipe and the magnet core (100) together at the position where the center (110) is arranged, avoiding the position of the magnet unit (120) among the magnet cores (100), according to the work plan confirmed through the barcode in step a-0). In addition, data on the pipe on which demolition is completed can be transmitted and received with the outside using the second process of the cutting unit. The above second process can analyze the outer diameter selection record and the data of the cutter (300), and transmit a report on the completion of the work to the outside.

[0094]

[0095] In one embodiment of the present invention, the magnetic measuring device of the present invention is characterized by being a demolition pipe identification device (200) that identifies a pipe to be demolished from the outside of the pipe.

[0096] The demolition pipe identification device (200) of the present invention is a device that can easily identify a pipe to be demolished from the outside when a specific pipe is to be demolished in a pipe system comprising a plurality of pipes. The demolition pipe identification device (200) of the present invention is characterized in that it can easily identify a pipe to be demolished by detecting the magnetic force of a magnetic core (100) inserted into the pipe to be demolished (11).

[0097] Here, the magnet core (100) inserted into the pipe (11) to be demolished may be a magnet having a specific magnetic force that is spaced apart from each other at equal intervals on the wire. At this time, the length of the magnet core can be confirmed by detecting the quantity of the magnets arranged. In addition, it is preferable that the magnet has a magnetic force that can be detected from the outside even when inserted into the pipe. More specifically, it is preferable that the magnet has a specific magnetic force value that is distinct from the magnetic force that can be detected in other external environments. The magnet may be configured to have a separate N pole and a S pole. Here, the N pole and the S pole may be arranged vertically in the vertical direction with respect to the wire. At this time, the magnet may have a random polarity arrangement, or the magnets arranged along the longitudinal direction of the wire may have a form in which adjacent parts have the same polarity, or different polarities are arranged alternately, which can be selected as needed. However, the strength of the magnetic force may vary depending on the arrangement of the polarities. The magnet is preferably formed to have a diameter smaller than that which can be inserted into the pipe (10), and can be formed integrally with the wire.

[0098] By inserting a magnetic core (100) having the above-described characteristics into a pipe (11) to be demolished, the pipe (11) to be demolished can be distinguished from a plurality of pipes. Referring to FIG. 11, the demolition pipe identification device (200) of the present invention is characterized in that it detects the magnetic force of the magnetic core (100) inserted into the pipe (10) from the outside of the pipe (10), thereby identifying whether the pipe is a pipe to be demolished.

[0099]

[0100] Referring to FIG. 12, the demolition pipe identification device (200) of the present invention may include a detection unit (210) that is arranged at one end and is formed in a shape in which at least the inner surface corresponds to the outer surface of the pipe (10) and is fastened to the pipe (10), an opening / closing means (220) that selectively opens or closes the detection unit (210), and a body part (230) that has the detection unit (210) on one side. Here, the detection unit (210) is characterized in that a plurality of magnetic sensors (213) that detect a specific magnetic force of a magnetic core (100) are provided and uniformly arranged along the inner surface.

[0101] In other words, as illustrated in FIG. 11, the demolition pipe identification device (200) of the present invention is characterized in that it can identify whether the pipe (10) is a pipe to be demolished or not by detecting the magnetic force of the pipe (10) by fastening a detection unit (210) arranged on one side from the body unit (230) to the outside of the pipe (10) and using a magnetic sensor (213) formed along the inner circumferential surface of the detection unit (210).

[0102] The sensing unit (210) of the present invention may be formed in a ring shape in which the inner circumference surrounds the outer circumference of the pipe (10). Referring to FIGS. 12 to 14, the sensing unit (210) is characterized in that the inner circumference of the sensing unit (210) has a circular shape corresponding to the outer circumference of the pipe (10) so that the inner circumference is fastened while making contact with the outer circumference of the pipe (10). Here, the sensing unit (210) may have a shape in which the first sensing unit (211) and the second sensing unit (212), each formed in a semicircular shape, are arranged to face each other so as to facilitate fastening to the pipe (10). That is, when the first detection unit (211) and the second detection unit (212) are in contact with each other, the device can be mounted on the pipe (10), and when the first detection unit (211) and the second detection unit (212) are separated from each other, the device can be in the shape of a forceps that can be detached from the pipe (10).

[0103] At this time, it is preferable that the diameter of the inner surface of the detection unit (210) corresponds to the diameter of the outer surface of the pipe (10) or is larger than the outer surface of the pipe (10). However, depending on the type or size of the pipe, the detection unit (210) may be detachable from the body part (230). In other words, the detection unit (210) may have various diameters and may be formed in multiple pieces, and, if necessary, the detection unit (210) may be replaced from the body part (230) according to the diameter of the pipe (10), thereby being configured to be usable in various pipes.

[0104] The demolition pipe identification device (200) of the present invention is characterized by including an opening / closing means (220) for detaching the detection unit (210) from the pipe (10). The opening / closing means (220) is characterized by being a means for selectively opening or closing the detection unit (210). That is, the opening / closing means (220) is characterized by being a means for opening or closing the detection unit (210) composed of the first detection unit (211) and the second detection unit (212) so as to open or close the space between the first detection unit (211) and the second detection unit (212). Here, the opening / closing means (220) may be configured without limitation as long as it is a means capable of opening or closing the first detection unit (211) and the second detection unit (212).

[0105] Referring to FIGS. 12 to 14, in one embodiment, the opening / closing means (220) of the present invention is characterized by a clamp-type structure in which a handle (220) protruding a predetermined size is formed on the body portion (230), and the space between the first sensing portion (211) and the second sensing portion (212) is opened by pressing the handle (220). The handle (220) may be arranged on one side of the body portion (230) where the sensing portion (210) is formed, and is preferably arranged on the other side than the sensing portion (210). When the handle (220) is not pressed, the first sensing portion (211) and the second sensing portion (212) are closed to each other, and when the handle (220) is pressed, the space between the first sensing portion (211) and the second sensing portion (212) is opened. At this time, the handle (220) may be formed as a pair that is arranged at both ends in parallel with the arrangement direction of the first detection unit (211) and the second detection unit (212), so that the handle (220) and the detection unit (210) arranged on the same line form a pair, and when the corresponding handle (220) is pressed, the corresponding detection unit (210) may be formed to perform an operation of opening. Here, the opening / closing means (220) may further include a spring (221) between the pair of handles (220), so that when the handle (220) is pressed, the first detection unit (211) and the second detection unit (212) are opened, and when the handle (220) is not pressed, the handle (220) returns to its original position by the elasticity of the spring (221), thereby closing the first detection unit (211) and the second detection unit (212).

[0106] The demolition pipe identification device (200) of the present invention is characterized in that it detects the magnetic force of a magnetic core (100) inserted into the inside of the pipe (10) from the outside of the pipe (10). Accordingly, the demolition pipe identification device (200) is characterized in that it has a plurality of magnetic sensors (213) that detect the magnetic force of the magnetic core (100). Here, referring to FIGS. 14 and 15, the magnetic sensor (213) is preferably arranged on the inner surface of the detection unit (210) that comes into contact with the outer surface of the pipe (10), among the detection units (210). In other words, the device is characterized in that a plurality of magnetic sensors (213) that detect a specific magnetic force of the magnetic core (100) are arranged in parallel along the inner surface of the detection unit (210). Accordingly, the demolition pipe identification device (200) of the present invention has a structure of a detection unit (210) whose inner surface is formed in a circular shape so as to come into contact with the outer surface of the pipe (10), and a magnetic sensor (213) is arranged along the inner surface of the detection unit (210), thereby detecting the magnetic force of the magnetic core (100) in all 360-degree sections of the pipe, and thus has the advantage of enabling more precise and accurate identification of the magnetic core (100).

[0107] Here, the magnetic sensor (213) of the present invention may be a Hall sensor, and the Hall sensor is characterized by being configured to distinguish between the N pole and the S pole. The magnet core (100) inserted inside the pipe (10) also distinguishes between the N pole and the S pole, and in particular, the N pole and the S pole of the magnet core (100) are vertically arranged along the up-down direction based on the wire. The magnetic sensor (213) of the present invention is characterized by being configured to distinguish between the N pole and the S pole in the Hall sensor so as to include a configuration of the Hall sensor for more accurately detecting magnetic force using the same.

[0108] And, referring to FIG. 15, the Hall sensor of the present invention includes an N pole and an S pole, and is characterized in that the N pole and the S pole are arranged in a direction parallel to each other along the radial direction of the detection unit (210). In other words, the N pole and the S pole of the Hall sensor are characterized in that the N pole and the S pole are arranged in a radial direction from the detection unit (210), and are arranged in a parallel direction that is in line with each other along the radial direction. Accordingly, with respect to the N pole and the S pole of the magnetic core (100) vertically arranged inside the pipe (10), the N pole and the S pole of each Hall sensor arranged to surround the inner circumference of the detection unit (210) may be perpendicular to or parallel to each other depending on their positions. Here, the magnetic sensors (213) arranged in parallel along the inner surface of the detection unit (210) may be arranged alternately so that the poles of the neighboring magnetic sensors (213) are opposite to each other, that is, so that the N and S poles of the neighboring magnetic sensors (213) arranged on the inner surface intersect each other. In addition, if necessary, the magnetic sensors (213) arranged in parallel along the inner surface of the detection unit (210) may be arranged so that the poles of the neighboring magnetic sensors (213) are parallel to each other, that is, so that all the poles of the neighboring magnetic sensors (213) are N or S poles.

[0109] The detection unit (210) of the present invention is preferably formed to be able to move on the surface of a pipe (10) forming a length and detect the magnetic force of a magnet core (100) inserted into the pipe (10). Accordingly, the detection unit (210) may be formed of at least one material among plastics having a low coefficient of friction, such as Teflon (PTFE), polyethylene (PE), polypropylene (PP), and polyacetal (POM), or nylon and fiberglass reinforced plastic (FRP), so as to move on the outer surface of the pipe (10). This is to provide an effect in which the demolition pipe identification device (200) can easily move its position and operate even on a long pipe (10) by forming the inner surface of the detection unit (210) itself of a material that can slide on the outer surface of the pipe (10). In addition, the detection unit (210) is characterized in that at least one roller or bearing is arranged along the inner surface so as to move on the outer surface of the pipe (10). Here, the roller or bearing is arranged in a direction protruding from the inner surface, and is preferably formed so as to be movable along the outer surface of the pipe (10). At this time, the inner surface diameter of the detection unit (210) is formed to be larger than the outer surface diameter of the pipe (10), so that the roller or bearing protruding from the inner surface of the detection unit (210) is in contact with the outer surface of the pipe (10), so that the demolition pipe identification device (200) can easily move its position on a long pipe.

[0110] The body (230) is a component that can be equipped with a detection unit (210) and an opening / closing means (220), as well as other necessary functions. The body (230) can also function as a handle (220) that allows a worker to hold the demolition pipe identification device (200). Accordingly, the body (230) can have a predetermined length in one direction, and can be configured such that the detection unit (210) and the opening / closing means (220) are arranged at one end. In addition, it is preferable that the body (230) be formed with a predetermined thickness so that the worker can easily hold it.

[0111] Referring to FIGS. 12 to 14, the body (230) may further include various devices that can perform additional functions required by the demolition pipe identification device (200), such as supplying power to the magnetic sensor (213) or displaying the detection result of the magnetic sensor (213). As an example, as illustrated in FIG. 14, the body (230) may be equipped with a battery (231) that supplies power to the demolition pipe identification device (200) including the magnetic sensor (213). In addition, as illustrated in FIG. 12, the body (230) may include an identification means (232) that outputs a color indicator light or a buzzer for the determination result when it determines whether the magnetic force detected by the magnetic sensor (213) is the magnetic force of the magnetic core (100) inserted inside the demolition target pipe (11). And, as illustrated in FIG. 14, the body part (230) may further include a connection part that is wired and interlocked with another device. The connection part can wire the demolition pipe identification device (200) to another device, and the body part (230) may be provided with a connector that can connect a necessary wire or cable, as needed. Here, the connection part of the present invention may include a motor connection part (237) that is connected to a motor (420) of a magnet core (100) supply device that supplies a magnet core (100) to the body part (230), and a cutter connection part (236) that is connected to a cutter (300) that cuts the pipe (10). The body part (230) may further be provided with wireless communication so that it can wirelessly connect to external devices and transmit and receive signals with each other. In addition, the body part (230) may be provided with various devices according to the functions required by the demolition pipe identification device (200).

[0112]

[0113] The demolition pipe identification device (200) of the present invention can be used in an insertion step of inserting a magnetic core into a target pipe (11) using the demolition pipe identification device (200) or a demolition work step of demolishing the target pipe. Accordingly, the demolition pipe identification device (200) is connected to a cutting machine (300) that cuts the demolition target pipe (11) in a manner that allows for signal transmission and reception, and the cutting machine (300) operates in conjunction with the demolition pipe identification device (200), thereby having the effect of preventing an accident of incorrect cutting during the demolition work of the target pipe.

[0114] Referring to FIG. 16, a cutting device (300) having a cutting blade (310) for cutting a pipe (10) in the present invention receives an operating signal and turns on the cutting device (300) so that the cutting blade (310) operates and can cut the pipe (10). That is, if the cutting device (300) of the present invention does not receive an operating signal, the cutting blade (310) does not operate and cannot cut the pipe (10). Here, the cutting device (300) of the present invention is characterized in that it can receive a signal from the demolition pipe identification device (200) regarding an operating signal for the cutting blade (310) to operate. To this end, the cutter (300) can be connected to the demolition pipe identification device (200) to transmit and receive signals with each other, and in one embodiment, can be connected to the cutter (300) by a wire through a cutter connection part (236) formed in the body part (230) of the demolition pipe identification device (200). When the demolition pipe identification device (200) detects a specific magnetic force for the magnetic core (100) inserted inside the pipe (10), the demolition pipe identification device (200) determines that the pipe is a pipe to be demolished, and the demolition pipe identification device (200) can transmit an operation signal to the cutter (300) by a wire. Accordingly, the cutter (300) is characterized in that it can be turned on by the operation signal received from the demolition pipe identification device (200), and the cutting blade (310) operates to cut the pipe (10).

[0115] Here, as illustrated in FIG. 16, a specific laser fired from the demolition pipe identification device (200) can be reflected from the cutter to the identification device, thereby confirming each other's positions. More specifically, the body (230) of the demolition pipe identification device (200) may include a laser sensor (233) capable of firing a laser, and a laser detection sensor (234) capable of detecting the laser sensor (233) from the outside, which may be positioned near the laser sensor (233). In addition, the cutter (300) may further include a reflector (320) capable of reflecting the laser fired by the laser sensor (233). Accordingly, when the magnetic sensor (213) of the demolition pipe identification device (200) detects the magnetic force of the magnetic core and confirms that the pipe is a pipe to be demolished (11), the laser sensor (233) fires a laser, and the positions of the demolition pipe identification device (200) and the cutter (300) are adjusted so that they face each other and the reflector (320) of the cutter (300), thereby enabling the positions of each other to be confirmed using the laser. And when the reflector (320) of the cutter (300) reflects the laser emitted from the laser sensor (233) and the laser is received by the laser detection sensor (234) located near the laser sensor (233) of the demolition pipe identification device (200), the demolition pipe identification device (200) determines that the cutter (300) is located at the pipe to be demolished (11), and the demolition pipe identification device (200) transmits an operation signal to the cutter (300), and the cutter (300) that has received the operation signal turns on and the cutting blade (310) can operate. In addition, the demolition pipe identification device (200) generates location information and transmits it to the cutter (300), and when the cutter (300) feeds back the location information received by the demolition pipe identification device (200), the cutter (300) turns on and the cutting blade (310) can operate.

[0116]

[0117] In addition, the demolition pipe identification device (200) of the present invention can be used in an insertion step of inserting a magnetic core (100) into a pipe (11) to be demolished using the demolition pipe identification device (200). The demolition pipe identification device (200) is linked to a motor (420) of a magnetic core insertion device (400) that inserts a magnetic core (100) into a pipe (11) to be demolished so as to be able to transmit and receive signals to and from each other, and detects the length of the magnetic core (100) inserted into the pipe (10) using a magnetic sensor (213) of the demolition pipe identification device (200), so that a necessary number of magnetic cores (100) can be inserted into the pipe (11) to be demolished in the insertion step.

[0118] Referring to FIG. 17, a magnet core insertion device (400) for inserting a magnet core (100) into a pipe (10) for a pipe to be demolished (11) includes an outlet (410) for withdrawing the magnet core (100) on one side. Accordingly, the magnet core (100) is withdrawn in one direction through the outlet (410) and inserted into the pipe (10). Here, the demolition pipe identification device (200) of the present invention can be mounted on the outlet (410) of the magnet core insertion device (400). That is, the detection unit (210) of the demolition pipe identification device (200) can be fastened to the outlet (410) of the magnet core insertion device (400) by surrounding the outer circumferential surface of the outlet (410). In addition, the demolition pipe identification device (200) can determine the length of the magnet core (100) by detecting the magnetic force of the magnet core (100) passing through the discharge port (410) using a magnetic sensor (213), and is characterized in that it can know the length of the magnet core (100) inserted into the target pipe (11).

[0119] Here, as illustrated in FIG. 13, the demolition pipe identification device (200) may further include a display (235) capable of outputting letters or numbers to the outside of the body (230). In addition, the display (235) may output the supply length of the magnet core (100) detected by the magnetic sensor (213) of the demolition pipe identification device (200). In addition, the magnet core insertion device (400) may be connected to the demolition pipe identification device (200) to transmit and receive signals with each other, and as illustrated in FIG. 17, in one embodiment, may be wired and linked to a motor (420) that extracts the magnet core (100) within the magnet core insertion device (400) through a motor connection (237) formed in the body (230) of the demolition pipe identification device (200).

[0120] The demolition pipe identification device (200) is characterized in that it is linked with the motor (420) of the magnet core insertion device (400), so that the demolition pipe identification device (200) can control the power of the motor (420) as needed. Accordingly, in the insertion step, the demolition pipe identification device (200) is fastened to the outlet (410) of the magnet core insertion device (400), and the demolition pipe identification device (200) detects the length of the magnet core (100) drawn out from the outlet (410), and can display the length of the supplied magnet core (100) through the display (235). And, the worker knows in advance the insertion length of the magnet core (100) to be inserted according to the length of the pipe to be demolished (11), or the length can be preset in the demolition pipe identification device (200), and when the length of the magnet core (100) detected through the magnetic sensor (213) reaches the preset length, the worker controls the motor (420) linked to the demolition pipe identification device (200) to stop the power, thereby stopping the insertion of the magnet core (100) into the pipe.

[0121] In addition, when the magnet core insertion device (400) introduces the magnet core (100) into the pipe through the outlet (410), compressed air can be supplied along the direction of movement of the magnet core (100) through the outlet (410) in order to provide a traction force for the magnet core (100). Here, the compressed air can be fired outward together with the magnet core (100) along the outlet (410) formed on one side by compressed air supplied into the housing of the magnet core insertion device (400). Here, the magnet core insertion devices (400) can be interlocked to control the supply of compressed air supplied to the magnet core insertion devices (400). Accordingly, in the insertion step, the demolition pipe identification device (200) is fastened to the outlet (410) of the magnet core insertion device (400), and the demolition pipe identification device (200) detects the length of the magnet core (100) withdrawn from the outlet (410) and can display the length of the supplied magnet core (100) through the display (235). In addition, the worker knows in advance the insertion length of the magnet core (100) to be inserted according to the length of the pipe (11) to be demolished, or the length can be preset in the demolition pipe identification device (200), and when the length of the magnet core (100) detected through the magnetic sensor (213) reaches the preset length, the compressed air linked to the demolition pipe identification device (200) can be controlled to stop the insertion of the magnet core.
