Description

Magnet core insertion device and movable magnet core insertion and retrieval system

[0001] The present invention relates to a magnet core insertion device capable of efficiently inserting a magnet core into a pipe having a predetermined diameter, and a movable magnet core insertion and recovery system capable of inserting a magnet core and recovering residue, and configured to be easily moved.

[0002] Pipelines are equipment used to transport liquids and gases. They are used in a wide range of industries, including petrochemical plants, power plants, water and sewage systems, gas supply networks, and semiconductor and display manufacturing plants. In particular, the pipes used in these industries are often tens to hundreds of meters long, and in some cases, they transport hazardous fluids that can be harmful to humans or the environment.

[0003] These pipes may need to be removed for reasons such as facility maintenance, process changes, or demolition. If the fluid remaining inside the pipe is hazardous, leakage of the fluid may cause damage to life and property. Therefore, it is very important to quickly and accurately identify the pipes to be removed.

[0004] Traditionally, demolition targets were identified by attaching identification numbers to the outside of the pipes or by referencing drawings. However, when the pipes are complexly intertwined or long, it can be difficult for workers to visually identify specific pipes. Furthermore, if the identification numbers are damaged by the external environment or the drawings are out of date, misidentification is possible. Furthermore, the reliance on worker judgment has led to problems such as low reliability.

[0005] To solve these problems, Korean Patent Publication No. 10-2024-0001281 (“Method for selecting pipes that can be identified from the outside and method for demolishing pipes to prevent incorrect cutting accidents using the same”, filed on January 4, 2024) proposes a method for identifying pipes to be demolished by inserting a magnetic core having magnetism into the inside of the pipe to be demolished and detecting the magnetic force of the magnetic core using a magnetic sensor from the outside of the pipe. More specifically, the method proposes forming a magnetic core by combining a magnetic substance having a specific magnetic force with a wire, inserting it into the pipe to be demolished, and then detecting the magnetic force from the outside to distinguish the pipes.

[0006] At this point, a process is required to insert the magnetic core into the pipe. Conventional methods include manually pushing the wire, using a mechanical pusher, installing a vacuum suction device at the end of the pipe to suck the wire in, or using compressed air to inject the wire. However, these devices are often fixed or large, limiting their mobility depending on the pipe location. Furthermore, separate magnetic core insertion and retrieval devices present challenges, resulting in poor interoperability in complex environments, making the process cumbersome and inefficient.

[0007] Furthermore, when the pipe diameter is small or the length is very long, insertion of the magnetic core can be difficult, making the process even more difficult. Therefore, a device is needed that can efficiently insert and retrieve the magnetic core inside the pipe, while also enhancing mobility and ease of use on the job site.

[0008] Accordingly, the present invention has been devised to solve the above problems, and more specifically, to provide a system having a structure capable of independently storing and supplying compressed gas so as to prevent pressure drop or insufficient flow rate of a compressed gas line constructed at a demolition work site when inserting and retrieving a magnet core using compressed gas, and further to provide a magnet core insertion device that can smoothly insert a magnet core having a magnet coupled to a wire into a pipe regardless of the diameter or length of the pipe, and to provide a continuous traction force applied to the magnet core by supplying compressed gas inside a sealed housing, and to continuously insert the magnet core into the pipe by pulling the magnet core closely through a plurality of friction rollers.

[0009] In addition, the system is configured to efficiently supply magnetic cores inside the pipe and safely recover residue inside the pipe, thereby improving the convenience and efficiency of work. In particular, the system is configured to store multiple devices required for demolition work in a movable frame and allow them to be easily transported to the work site, thereby improving the efficiency of moving to the work site. A movable magnetic core insertion and recovery system is provided.

[0010] A magnet core insertion device according to the present invention, which inserts a magnet core, in which a magnet is arranged at a predetermined interval on a wire, into a pipe, comprises: a housing forming a sealed internal space; a gas inlet for supplying compressed gas into the interior of the housing; a magnet core bundle accommodated in the internal space of the housing, in which the magnet core is wound, and which discharges the magnet core by rotation; at least one conveying roller for pulling the magnet core from the magnet core bundle; and an outlet connected to the pipe, through which the magnet core and the compressed gas are discharged.

[0011] Next, the mobile magnet core insertion and retrieval system according to the present invention comprises: a main body frame having one or more wheels formed to support the ground, a separate receiving space formed by a plurality of frames at the front, and a handle at the rear; and an insertion device disposed in the receiving space, the main body frame including a magnet core wound therein, the insertion device connecting a pipe to be demolished to an outlet formed at one side, and supplying compressed gas to a gas inlet formed at the other side to insert the magnet core into the pipe.

[0012] The magnet core insertion device of the present invention, having the above configuration, is a device configured to stably insert various types of magnet cores into a pipe regardless of the thickness of the wire, the size of the magnet, or the presence or absence and size of the guide ball, such that the magnet core is transported into the pipe while passing through a plurality of rollers, and the rollers are supplied with power to rotate, thereby providing continuous traction to the magnet core, and by bringing the magnet core into close contact with the friction surface, there is an effect of smoothly transporting the magnet core in one direction without tangling. By performing the magnet core insertion process using such a magnet core insertion device, the efficiency, accuracy, stability, and reliability of the process can be improved.

[0013] In addition, the mobile magnetic core insertion and retrieval system of the present invention can stably insert a magnetic core or effectively retrieve residue within a pipe using compressed gas, and insertion and retrieval using compressed gas are possible while minimizing damage to the magnetic core. In addition, by configuring the entire device on a movable frame, the time and effort of installing and dismantling individual equipment each time the work location changes can be reduced, and since multiple pieces of equipment required for pipe demolition work can be integrated into a single frame and transported simultaneously, workers can perform the insertion and retrieval of magnetic cores continuously in the same location, thereby reducing work time and greatly improving work efficiency. In addition, the equipment within the frame can be independently separated and installed, making maintenance and management of the system easy, and enabling a quick response to problems that may arise during pipe demolition work.

[0043] Hereinafter, the technical concept of the present invention will be described in more detail using the attached drawings. Prior to this, it should be noted that the terms and words used in this specification and claims should not be construed as limited to their conventional or dictionary meanings. Based on the principle that the inventor can appropriately define the concept of a term to best explain his or her invention, they should be interpreted in a way that aligns with the technical concept of the present invention.

[0044] Therefore, it should be understood that the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention, and that there may be various modified examples that can replace them at the time of filing this application.

[0045] Hereinafter, the technical concept of the present invention will be described in more detail using the attached drawings. The attached drawings are merely examples provided to more specifically explain the technical concept of the present invention, and therefore, the technical concept of the present invention is not limited to the form of the attached drawings.

[0046] The magnet core insertion device of the present invention is configured to be able to insert a magnet core into a pipe having a long length or a predetermined diameter. At this time, the magnet core insertion device of the present invention is characterized by including a configuration that provides a traction force to the magnet core, thereby smoothly inserting the magnet core into a required position inside the pipe, regardless of the wire thickness of the magnet core, the size of the magnet, the presence or absence of a guide ball, or the size of the guide ball.

[0047] Fig. 1 (a) is a first embodiment of a magnet core configuration diagram of the present invention, and Fig. 1 (b) is a second embodiment of a magnet core configuration diagram of the present invention. Referring to Fig. 1, the magnet core (201) may be a magnet (203) having a certain size or more or a specific magnetic force, spaced apart at equal intervals on a wire (202). At this time, it is preferable that the magnet (203) has a magnetic force that can detect that it is the magnet (203) from the outside even when inserted into a pipe. The magnet (203) may be configured to have a distinct N pole and a S pole, and the N pole and the S pole may be arranged vertically in the vertical direction with respect to the wire (202). At this time, the magnet (203) may be arranged randomly in polarity, or the magnets (203) arranged along the length direction of the wire (202) may have adjacent parts with the same polarity or may have different polarities arranged alternately, which may be selected as needed. However, the strength of the magnetic force may vary depending on the arrangement of the polarity. The magnet (203) is preferably formed to have a diameter smaller than that which can be inserted into the pipe, and may be formed integrally with the wire (202).

[0048] In addition, referring to (a) of FIG. 1, the magnet core (201) of the present invention may have guide balls (204) arranged at adjacent front and rear ends of magnets (203) spaced at equal intervals. At this time, the magnet core (201) may be arranged as a set of a magnet (203) and a pair of guide balls (204) with equal intervals on a wire (202), and the wire (202) and the guide balls (204) may be formed as an integral part. In addition, referring to (b) of FIG. 1, the guide balls (204) may be arranged to surround the outer surface of the magnet (203), so that the guide balls (204) and the magnet (203) may be integrally formed. By adjusting the spacing between the guide balls (204) and the magnets (203) of the magnet core (201) as needed, the length of the magnet core (201) can be confirmed by checking the spacing. The present invention configures the magnet core (201) in a form in which the magnets (203) are arranged at a constant interval on the wire (202), so that the magnet core (201) can be smoothly transported by the guide balls (204) by arranging the guide balls (204) at the front and rear ends of the magnets (203). In addition, since the spacing between the magnets (203) and the guide balls (204) on the wire (202) is formed at a constant length, the length of the magnet core (201) can be easily confirmed, so that the length of the inserted magnet core (201) can be easily calculated or the position of the magnet core (201) can be precisely controlled inside the pipe. The above-mentioned induction ball (204) can be formed without limitation in its material as needed, and can be configured to have a certain weight, or can be manufactured from plastic to reduce the unit price.

[0049] In a case where a pipe is to be identified from the outside through a magnet core (201) having the above-described characteristics, a process of inserting the magnet core (201) into the inside of the pipe is required. The present invention relates to a device for inserting a magnet core (201) into the inside of a pipe, and in particular, when the length of the pipe is very long, the diameter of the pipe is small, or due to various external factors, the magnet core (201) may be blocked when inserted into the pipe, the magnet cores (201) may become entangled with each other, the supply speed balance may be broken, and there may be an excessive loosening problem, and the like, and the device is configured to enable the magnet core (201) to be inserted smoothly.

[0050] In particular, the present invention operates based on providing a traction force to the magnet core (201) by supplying compressed gas to insert the magnet core (201). Accordingly, the magnet core insertion device (200) is characterized in that when the supply of compressed gas is cut off, the magnet core (201) is separated from the transport roller and the supply is stopped, and even when the magnet core (201) is transported while being brought into close contact with the friction roller by supplying compressed gas, the transport of the magnet core (201) can be stopped by stopping the power of the elastic roller. This will be described in more detail below.

[0051] The present invention is characterized by a magnet core (201) insertion device that inserts a magnet core (201) having magnets (203) having a predetermined magnetic force spaced at equal intervals on at least a wire (202) into a pipe having a predetermined diameter. Fig. 2 is an external schematic diagram of a magnet core insertion device according to an embodiment of the present invention, Fig. 3 is a perspective view 1 of the internal structure of a magnet core insertion device according to an embodiment of the present invention, and Fig. 4 is a perspective view 2 of the internal structure of a magnet core insertion device according to an embodiment of the present invention. Referring to FIGS. 2 to 4, the magnet core (201) insertion device may include a housing (210) that forms a sealed internal space, a gas inlet (212) that supplies compressed gas to the housing (210), a discharge port (213) that is formed on the outside of the housing (210) in the direction of travel and is connected to the pipe so that the magnet core (201) is discharged together with the compressed gas and introduced into the pipe, a magnet core bundle (220) that is accommodated in the internal space and pulls out the coiled magnet core (201) in the direction of travel, and at least one transfer roller (230) that is accommodated in the internal space and has at least an outer circumferential surface formed of an elastic material so as to be in close contact with the magnet core (201) pulled out by the magnet core bundle (220) and transfer the magnet core (201) in the direction of travel.

[0052] Referring to FIG. 2, the housing (210) can serve as a frame constituting the magnet core (201) insertion device. The housing (210) includes an internal space capable of accommodating major components, and is particularly characterized by forming the internal space in a sealed manner. It is preferable that the housing (210) include, in the internal space, at least a magnet core bundle (220) in which a magnet core (201) is wound, and at least one transport roller (230). In addition, FIG. 3 is a perspective view 1 of the internal structure of a magnet core insertion device according to an embodiment of the present invention, and FIG. 4 is a perspective view 2 of the internal structure of a magnet core insertion device according to an embodiment of the present invention. As shown in FIGS. 3 and 4, the housing (210) can have a circular plate disposed in the internal space, and the magnet core bundle (220) and the transport rollers (230) can be coupled to the plate at respective positions to configure the device. The above plate may be configured to fix components provided inside the housing (210). That is, the plate may be a component capable of forming an internal space.

[0053] At this time, since the magnet core (201) flows inside the housing (210), it is preferable that at least the configuration of the housing (210), the gas inlet (212), the magnet core bundle (220), the conveying roller (230), and the outlet (213), as well as all parts accommodated in the internal space of the housing (210) be formed of a non-magnetic material. Accordingly, the magnet core (201) can be prevented from sticking to the internal parts. In addition, the housing (210) is characterized in that it includes a transparent window (211) on at least a portion of the outer surface for observing the accommodation space inside the housing (210). The internal situation of the housing (210) can be confirmed through the transparent window (211).

[0054] Here, the present invention is a device that provides traction to the magnet core (201) by forming a flow and velocity of gas inside the pipe by supplying compressed gas inside the pipe into which the magnet core (201) is inserted. That is, it is characterized by supplying compressed gas inside the housing (210) to guide the magnet core (201) inside the pipe by utilizing the flow of gas. At this time, in order to effectively use the compressed gas, it is preferable that the housing (210) is formed in a sealed structure. The housing (210) includes an outlet (213) through which the magnet core (201) is withdrawn, and the outer end of the outlet (213) is connected to the pipe into which the magnet core (201) is to be inserted. Accordingly, when compressed gas is supplied into the housing (210), the compressed gas provides a traction force to the magnet core (201) and is supplied together with the magnet core (201) into the pipe through the discharge port (213), and the magnet core (201) is inserted into the pipe by the formed gas flow. That is, the present invention is characterized in that when compressed gas is supplied into the housing (210), the magnet core (201) moves in the direction of travel and receives a predetermined traction force to come into close contact with a plurality of transfer rollers (230) and is supplied into the pipe through the discharge port (213).

[0055] Referring to FIGS. 2 and 3, the discharge port (213) is characterized in that it discharges the magnet core (201) conveyed in the forward direction through at least one conveying roller (230) to the outside of the housing (210). It is preferable that the discharge port (213) has an end connected to a pipe so that the magnet core (201) discharged through the discharge port (213) is introduced into the pipe. It is preferable that the discharge port (213) is formed on the opposite side of the magnet core bundle (220) in the forward direction in the plate constituting the internal space of the housing (210). That is, when the magnet core bundle (220) is arranged on the other side of the plate, the discharge port (213) can be arranged on one side. However, the magnet core bundle (220) and the discharge port (213) do not have to be arranged at the same horizontal level. This is because the transfer rollers (230) are arranged to be misaligned with each other, and the magnet cores (201) are transferred through them. Therefore, it is preferable that the height of the discharge port (213) be determined by considering the position of the fourth transfer roller (230) (234), which is the last roller that transfers the magnet cores (201). Accordingly, the discharge port (213) may be arranged above the magnet core bundle (220).

[0056] At this time, the discharge port (213) may include a hall sensor that detects the magnetic force of the magnet core (201) on the inside. The hall sensor is for calculating the length of the magnet core (201) inserted into the pipe to be demolished. When the length of the pipe to be demolished is input, the hall sensor inserts the magnet core (201) by the input length, and stops the supply of power or gas to stop the supply of the magnet core (201). Accordingly, the hall sensor is characterized in that, when the insertion of the magnet core (201) into the pipe is completed and the magnetic force is detected, the supply of the magnet core (201) is stopped by cutting off the power of the motor (260) that operates the conveying roller (230) or cutting off the supply of compressed gas. In addition, the housing (210) includes a relief valve that detects the pressure of the internal space and discharges the pressure to the outside of the housing (210) when the internal pressure is above a certain level. This is to prevent the housing (210) from exploding or being damaged when a pressure exceeding a certain level is formed inside the housing (210). In other words, the relief valve is a valve that maintains the pressure inside the housing (210) by releasing it to the outside of the housing (210) when a pressure exceeding the pressure set in the housing (210) is supplied.

[0057] In addition, referring to FIGS. 2 and 3, the housing (210) is characterized by including a gas inlet (212) formed on the opposite side of the outlet (213) and adjacent to the magnet core bundle (220). The gas inlet (212) is an inlet through which compressed gas can be supplied into the sealed housing (210). Considering the direction of travel of the magnet core (201), if the outlet (213) is arranged on one side of the housing (210), it can be arranged on the opposite side of the housing (210) so that the compressed gas can be supplied in one direction. At this time, the gas inlet (212) can be formed at a horizontal position with respect to the magnet core bundle (220) and can be located lower than the outlet (213). Compressed gas is supplied into the housing (210) through the above gas inlet (212), and the supplied compressed gas can move along the outlet (213) inside the sealed housing (210) and flow into the pipe. At this time, when the compressed gas is supplied, the magnet core (201) wound around the magnet core bundle (220) is transported along the direction of travel and can flow into the pipe together with the compressed air along the outlet (213).

[0058] Referring to FIGS. 3 and 4, the magnet core bundle (220) is a device that is accommodated in the internal space of the housing (210), winds the magnet core (201), and, when necessary, withdraws the magnet core (201) in the direction of travel. The magnet core bundle (220) can be arranged to be biased to one side within the housing (210), and the magnet core (201) can move along the direction of travel from that position. For example, when the direction of travel of the magnet core (201) is one direction, the magnet core bundle (220) can be arranged on the other side within the internal space of the housing (210) to supply the magnet core (201) to one side. In addition, it is preferable that the magnet core bundle (220) be arranged at a position at least horizontal to the center line within the internal space. At this time, the center line is a center line that divides the internal space in a horizontal direction, and the upper and lower parts based on the center line can have the same length. Accordingly, the axial direction of the magnet core bundle (220) can be positioned horizontally parallel to the center line. The magnet core bundle (220) is configured to wind a magnet core (201) composed of at least a wire (202) including a magnet, and is preferably formed to a size capable of winding a wire (202) longer than the length of the target pipe.

[0059] In addition, the magnet core bundle (220) may include a structure in which one side is fixed to a plate inside the housing (210) and a wire (202) wound on the other side can be unwound. FIG. 5 is a side view of a magnet core bundle according to an embodiment of the present invention, and FIG. 6 is a side view of the internal structure of a magnet core insertion device according to an embodiment of the present invention. Referring to FIGS. 5 and 6, the magnet core bundle (220) includes a central axis (221) of which one end is fixed to the plate, a winding part (222) that is coupled to the central axis (221) and winds the magnet core (201), a spring (223) disposed between the winding part (222) and the plate, and a thrust bearing disposed between the spring (223) and the winding part (222). The above thrust bearing is a bearing that acts with an axial load, and is configured to prevent rotation due to acceleration or centrifugal force when the magnet core bundle (220) rotates at high speed and then stops by applying an appropriate preload to the bearing. At this time, the winding part (222) can be pressurized by the spring (223), and the preload of the winding part (222) can be adjusted according to the degree of pressurization. The spring (223) is characterized by being a device that applies a preload so that the magnet core (201) does not come loose due to acceleration when the magnet core (201) is supplied to rotate at high speed while being in close contact with an elastic roller and then stops.

[0060] FIG. 6 is a side view of the internal structure of a magnet core insertion device according to an embodiment of the present invention, and FIG. 7 is a front view of the internal structure of a magnet core insertion device according to an embodiment of the present invention. Referring to FIGS. 6 and 7, at least one conveying roller (230) is a device that is accommodated in the internal space of the housing (210) and conveys the magnet core (201) wound on the inwinder in the forward direction. In particular, the conveying roller (230) of the present invention is characterized in that at least the outer surface that interfaces with the magnet core (201) is formed of an elastic material. This is characterized in that, when the magnet core (201) comes into contact with the outer surface of the conveying roller (230), the force extracted by the frictional force is smoothly provided while making more close contact. Here, the conveying roller (230) is characterized in that it receives power from a motor (260) and rotates in order to convey the magnet core (201) in the forward direction. However, when the supply of compressed gas to the magnet core (201) is cut off, the magnet core (201) is separated from the conveying roller (230) and the supply of the magnet core (201) is cut off. In addition, even if the compressed gas is supplied and the magnet core (201) is supplied in a state of being in close contact with the conveying roller (230), the supply of the magnet core (201) may be cut off when the power of the motor (260) is stopped. At this time, the progress speed of the magnet core (201) can be controlled by controlling the rotation of the motor (260). That is, first, the magnet core (201) is in a state of being in close contact with the conveying roller (230) by providing a minimum traction force according to the gas flow of the compressed gas. And the conveying roller (230) is characterized in that when the motor (260) operates, the connected rotary shaft (224) rotates, and when the power is transmitted and each rotates, the magnetic core (201) is conveyed in the forward direction by the rotational force of the roller and the frictional force of the outer surface.

[0061] Referring to FIGS. 3 and 4, a plurality of transport rollers (230) may be provided, and may be respectively arranged at specific positions on a plate forming the internal space of the housing (210). Here, the transport rollers (230) may be arranged at specific positions between the magnet core bundle (220) around which the magnet core (201) is wound and the discharge port (213) that supplies the magnet core (201) to the pipe, so that the magnet core (201) is transported along the direction of travel. Describing in more detail with reference to FIG. 11, the plurality of transport rollers (230) are characterized in that at least one transport roller (230) is arranged from the magnet core bundle (220) to the discharge port (213) along the direction of travel of the magnet core (201). In one embodiment of the present invention, the plurality of transport rollers (230) may be sequentially arranged as a first transport roller (231), a second transport roller (232), a third transport roller (233), and a fourth transport roller (234) along the direction of travel of the magnet core (201). At this time, the number of transport rollers (230) is not limited, and may be less or more than this, and may be selected as needed.

[0062] The present invention is characterized in that the conveying rollers (230) are arranged within a plate, and the magnet cores (201) are arranged to sequentially reach and contact the first conveying roller (231), the second conveying roller (232), the third conveying roller (233), and the fourth conveying roller (234) from the magnet core bundle (220). At this time, the specific position of the conveying rollers (230) is characterized in that the arrangement structure can have a structure that can efficiently provide traction force to the magnet cores (201). This can be changed without limitation as needed or depending on various factors such as the number of conveying rollers (230).

[0063] FIG. 6 is a side view of the internal structure of a magnet core insertion device according to an embodiment of the present invention, FIG. 7 is a front view of the internal structure of a magnet core insertion device according to an embodiment of the present invention, and FIG. 8 is a diagram showing the arrangement structure of an inwinder, a conveying roller, and a motor according to an embodiment of the present invention. Referring to FIGS. 6 to 8, an arrangement structure of a plurality of conveying rollers (230) according to an embodiment of the present invention will be described. As illustrated in FIG. 7, the plates forming the internal space may be arranged such that the axial directions of the magnet core bundles (220) are parallel to each other at positions parallel to the center line in the horizontal direction based on the center line. In addition, when the magnet cores (201) advance in one direction, the magnet core bundles (220) may be located on the other side of the plate. That is, the magnet core bundles (220) may be arranged on the other side of the center portion of the plate. And, as the transport rollers (230), the first transport roller (231), the second transport roller (232), the third transport roller (233), and the fourth transport roller (234) can be arranged along one direction. However, the transport rollers (230) can be arranged at different positions in the vertical direction. This can be a specific arrangement form for effectively pulling the magnet core (201) and also for driving a plurality of rollers through a single power source. For example, the first transport roller (231) may be arranged above the magnet core bundle (220), the second transport roller (232) may be arranged below the magnet core bundle (220), the third transport roller (233) may be arranged below the first transport roller (231), and the fourth transport roller (234) may be arranged above the third transport roller (233). In addition, with respect to the center line, the first transport roller (231), the third transport roller (233), and the fourth transport roller (234) may be arranged at the upper end, and the second transport roller (232) may be arranged at the lower end. The transport rollers (230) arranged in the above arrangement form bring the magnet cores (201) out and into contact in the order of their numbers along the direction of travel.

[0064] Referring to FIGS. 7 and 8, more specifically, the plurality of transport rollers (230) are characterized in that they are formed to all rotate at the same speed using one motor (260). Accordingly, the structure is characterized in that the rotational force of the motor (260) can be transmitted to each transport roller (230). At this time, the motor (260) can apply power to the rollers by rotating the drive shaft. In addition, the drive shaft of the motor (260) can be arranged on the plate forming the internal space, below the third transport roller (233) and the fourth transport roller (234), and above the second transport roller (232). In addition, the drive shaft of the motor (260) can be arranged on one side, which is the opposite side of the magnet core bundle (220). That is, the driving shaft of the motor (260) may be positioned at a horizontal position on one side of the plate, approximately between the third transport roller (233) and the fourth transport roller (234), and at a vertical position lower than the center line, approximately between the second transport roller (232) and the third transport roller (233).

[0065] In addition, the present invention is characterized in that it includes at least one drive among a belt drive and a gear drive so that all rollers can be driven at the same speed while transmitting the driving force generated by the motor (260) to the first transport roller (231), the second transport roller (232), the third transport roller (233), and the fourth transport roller (234). For example, the first transport roller (231), the second transport roller (232), the third transport roller (233), and the fourth transport roller (234) may include a belt drive and a gear drive.

[0066] Referring to FIGS. 7 and 8 for more detailed explanation, first, the drive shaft of the motor (260) can be connected to adjacently positioned transfer rollers (230) by a belt (240), thereby forming a belt drive. At this time, the present invention can form two belt drives by connecting the second transfer roller (232) and the fourth transfer roller (234) from the drive shaft by separate belts (240). That is, the drive shaft of the motor (260) and the second transfer roller (232) are connected by a first belt (241), and the drive shaft of the motor (260) and the fourth transfer roller (234) are connected by a second belt (242), so that each of the second transfer roller (232) and the fourth transfer roller (234) can receive power from the drive shaft and rotate at the same speed. Here, when the drive shaft of the motor (260) rotates in the forward direction, both the second transport roller (232) and the fourth transport roller (234) connected to each belt (240) can rotate in the forward direction. In addition, the first belt (241) and the second belt (242) may have the same or different lengths depending on the straight-line distance from the drive shaft to the position of each transport roller (230). In the present invention, the distance of the fourth transport roller (234) from the drive shaft is longer than the distance from the second transport roller (232), so that the second belt (242) can be formed to have a longer length than the first belt (241).

[0067] Here, the present invention may further include a tension roller (270) for adjusting the tension of the second belt (242). As illustrated in FIGS. 7 and 8, the tension roller (270) is characterized in that it is positioned between the fourth transport roller (234) and the drive shaft at a position where one side of the second belt (242) can be pressed. In particular, the tension roller (270) is characterized in that it is formed to press the second belt (242) to the other side while contacting one side of the second belt (242) in order to press the second belt (242) in the opposite direction to the moving direction. The tension roller (270) is characterized in that it is provided to adjust the tension of the second belt (242).

[0068] And, the fourth transport roller (234) that rotates by the second belt (242) is arranged with the third transport roller (233) at an adjacent position. Accordingly, as illustrated in FIGS. 6 to 8, the present invention is configured such that the outer peripheral surfaces of the third transport roller (233) and the fourth transport roller (234) each include a gear (250), and the teeth of each gear (250) are formed to mesh with each other, thereby forming a gear drive. Here, when the drive shaft of the motor (260) rotates in the forward direction, the fourth transport roller (234) rotates in the forward direction by the second belt (242), and the third transport roller (233) that includes the first gear (251) that meshes with the second gear (252) and rotates can rotate in the reverse direction, which is the opposite direction to the fourth transport roller (234). In addition, the third transport roller (233) may be arranged lower than the fourth transport roller (234). In other words, a first gear (251) may be formed on the outer circumference of the third transport roller (233), and a second gear (252) may be formed on the outer circumference of the fourth transport roller (234). The first gear (251) and the second gear (252) are characterized in that they are formed with an appropriate diameter so that their teeth contact each other. Here, the fourth transport roller (234) is characterized in that the second gear (252) is formed on the outer circumference while accommodating the second belt (242). Accordingly, the fourth transfer roller (234) that rotates by receiving power from the drive shaft of the motor (260) by the second belt (242) is characterized in that the fourth transfer roller (234) can rotate at the same speed by means of a gear drive.

[0069] In addition, as illustrated in FIGS. 7 and 8, the third transport roller (233) that rotates by a gear drive may be connected to the adjacent first transport roller (231) by a third belt (243) to form a belt drive. At this time, the first transport roller (231) may be positioned above the third transport roller (233). Here, the third transport roller (233) is characterized in that it is connected to the third belt (243) while forming a first gear (251) on the outer surface. And, when the drive shaft of the motor (260) rotates in the forward direction, the fourth transfer roller (234) rotates in the forward direction by the second belt (242), the third transfer roller (233) rotates in the reverse direction by the gears (250) interlocking and rotating with each other, and the first transfer roller (231) can rotate in the same reverse direction as the third transfer roller (233) by the third belt (243). Accordingly, the first gear (251) of the third transport roller (233) is meshed with the second gear (252) of the fourth transport roller (234) and rotates at the same speed, and the third transport roller (233) forms a belt drive with the first transport roller (231) by a third belt (243), so that the second transport roller (232) can also rotate at the same speed as the third transport roller (233).

[0070] As a result, since one motor (260) can rotate the first transport roller (231), the second transport roller (232), the third transport roller (233), and the fourth transport roller (234) at the same speed, the cost of driving the device can be reduced, the power consumption can be reduced, and the device can be easily maintained. In addition, the arrangement space of the plurality of transport rollers (230) can be efficiently used, and since the plurality of rollers can rotate at the same speed, the magnet core (201) can be stably supplied, while the reliability of the device can be improved. Since the magnet core (201) can be transported in an appropriately tensioned state by the plurality of transport rollers (230) having the arrangement form as shown in FIG. 7, the problem of twisting can be prevented, and since the magnet core moves in close contact with the friction surface of each roller without being excessively loosened due to the gap between the rollers, the transport of the magnet core can be performed smoothly.

[0071] Taking this into consideration, the operation of each transport roller (230) based on the extracted magnet core (201) will be described. Referring to FIG. 7, first, the magnet core bundle (220) arranged on one side of the housing (210) can rotate in the forward direction and extract the magnet core (201) to the first transport roller (231). Then, the first transport roller (231), which is adjacent to the unwinder and located higher, rotates in the reverse direction and transports the magnet core (201) to the second transport roller (232), which is located lower than the first transport roller (231). Then, the second transport roller (232) rotates in the forward direction and transports the magnet core (201) to the third transport roller (233), which is located higher than the second transport roller (232). And, the third transport roller (233) rotates in the reverse direction and transfers the magnet core (201) to the fourth transport roller (234) located above the third transport roller (233) and having teeth of a gear (250) that mesh with each other and rotate. At this time, the fourth transport roller (234) rotates in the forward direction to discharge the magnet core (201) to the discharge port (213) of the housing (210). That is, the plurality of transport rollers (230) arranged in the arrangement as shown in FIG. 8 can transfer the magnet core (201) while the adjacent transport rollers (230) rotate in opposite directions.

[0072] Next, the mobile magnetic core insertion and recovery system (1000) of the present invention is characterized in that, when demolishing a pipe, a magnetic core (201) having a specific magnetic force is inserted into the inside of the pipe to be demolished, and at this time, the magnetic force of the magnetic core (201) is detected from the outside of the pipe to identify the pipe to be demolished, and after demolishing the pipe to be demolished, a device capable of removing hazardous substances inside the pipe is configured as a single system (1000). That is, the mobile magnetic core insertion and recovery system of the present invention is characterized in that the devices used to identify and demolish a pipe using the magnetic core (201) and to recover residue inside the pipe are configured as an all-in-one system (1000).

[0073] Here, the magnet core (201) is a magnetic substance that includes a magnetic force that can be distinguished even from the outside of the pipe, and can be formed without limitation as long as it has a structure that can exhibit a magnetic force when inserted into the pipe. The magnet core (201) of the present invention includes a magnetic substance that is inserted into the pipe, and may be a magnetic substance having a specific magnetic force that can be detected even from the outside of the pipe combined with a wire (202) or the like having a length along the length of the pipe. At this time, the magnet core (201) may be in a form in which the magnetic substance is arranged at a certain interval along the length of the wire (202), and at this time, in order to facilitate the introduction into the inside of the pipe, an induction ball (204) may be combined together at the front and rear ends of the magnetic substance. The magnet core (201) may be configured so that the length of the magnet core (201) can be measured by adjusting the interval of the magnetic substance arrangement. The above magnetic core (201) can be configured by determining the type or diameter of the wire (202) according to the size of the pipe, and also determining the magnetic force strength or diameter of the magnetic body as needed.

[0074] The mobile magnetic core insertion and recovery system (1000) (hereinafter referred to as the 'system') of the present invention preferably comprises at least a device for inserting a magnetic core (201) into a pipe, a sensor for detecting that the magnetic core (201) has reached a recovery device (300) installed at the end of a demolition pipe, and a device for safely recovering residue existing in the demolition pipe. Fig. 9 is an overall perspective view of a mobile magnetic core insertion and recovery system equipped with a recovery device according to an embodiment of the present invention, Fig. 10 is a front view of a mobile magnetic core insertion and recovery system equipped with a recovery device according to an embodiment of the present invention, and Fig. 11 is a side view of a mobile magnetic core insertion and recovery system equipped with a recovery device according to an embodiment of the present invention. In addition, FIG. 12 is a plan view of a mobile magnet core insertion and recovery system equipped with a recovery device according to an embodiment of the present invention, and FIG. 13 is a full perspective view of a mobile magnet core insertion and recovery system with a recovery device detached according to an embodiment of the present invention. Referring to FIGS. 9 to 13, the system (1000) of the present invention is characterized by including a main body frame (100) having one or more main body wheels (140) formed to support the ground, a separate receiving space (110) formed by a plurality of frames at the front, and a handle (120) at the rear, an insertion device (200) disposed in the receiving space (110) and including a magnet core (201) wound inside, connecting an external pipe to be demolished to an outlet formed at one side, supplying compressed gas to a gas inlet formed at the other side, and inserting the magnet core (201) into the inside of the pipe using the compressed gas, and a recovery device (300) disposed so as to be mountable and detachable in the receiving space (110) and recovering residues including harmful gases remaining inside the external pipe.Here, since the insertion device (200) inserts the magnetic core (201) into the pipe using compressed gas, it is preferable that the main body frame (100) be able to carry at least one gas cylinder storing compressed gas.

[0075] Referring to FIGS. 9 to 12, the main body frame (100) may be a device that constitutes the entire frame of the system (1000). That is, the main body frame (100) is characterized in that it is formed so as to be able to accommodate all devices used in the pipe removal device, including the magnetic core (201). Here, the main body frame (100) is characterized in that it is formed so as to be movable. Accordingly, the main body frame (100) is characterized in that it has a structure in which one or more main body wheels (140) are formed to support the ground, so that the main body frame (100) can be moved by the main body wheels (140). That is, the main body wheels (140) may be arranged at the bottom portion of the main body frame (100), so that the bottom portion of the main body frame (100) may be positioned at a predetermined height from the ground by the main body wheels (140). Here, the bottom portion of the main body frame (100) is preferably an area corresponding to the lowest portion of the entire area constituting the system (1000). In addition, as illustrated in FIGS. 9 and 13, the main body frame (100) may further include a safety guide that can prevent collisions with facilities or people's feet from getting caught in the main body wheel (140). The safety guide may be formed in a form that surrounds the outside of the main body wheel (140). The safety guide may be configured to be attachable or detachable as needed.

[0076] Referring to FIGS. 9 and 10, the main body frame (100) of the present invention may have a structure that moves forward in the front direction. With this as a reference, a separate receiving space (110) formed by a plurality of frames may be arranged on the front side of the main body frame (100), and a handle (120) that a user holds and pushes or pulls may be arranged on the rear side. That is, the main body frame (100) may be of a type that moves in a state where the receiving space (110) is arranged on the front side by pushing or pulling the handle (120) arranged on the rear end. The above main body frame (100) is configured to be movable, so that it is easy to carry equipment used in pipe demolition work, thereby reducing the time and effort required to install and dismantle equipment each time the work location changes. In addition, since a plurality of equipment required for pipe demolition work can be configured together in one main body frame (100) and transported simultaneously, a worker can continuously perform insertion and retrieval operations of a magnet core (201) in one location, thereby reducing work time and greatly improving work efficiency.

[0077] In general, when demolishing a pipe, depending on the demolition environment, there are cases where there is no compressed gas to be used, or if the compressed gas on site is used in the magnet core supply device, it may affect the peripheral equipment that uses the compressed gas (pressure drop in the compressed gas pipe, insufficient flow rate, etc.). Therefore, its use is prohibited. The present invention is intended to solve such problems, and is characterized in that the compressed gas required to insert the magnet core into the demolition pipe can be stored and used in a separate location in the main body frame (100). Referring to FIGS. 9 and 10, the main body frame (100) may include a floor frame (130) of a predetermined area at a height spaced from the ground between the rear end of the receiving space (110) and the handle (120), and a compressed gas cylinder may be accommodated in the floor frame (130). This is characterized by a structure for arranging the gas cylinder on the side of the handle (120) so that the gas cylinder can be moved stably when moved while being accommodated in the main body frame (100), since the gas cylinder of the compressed gas is generally heavy and may be tall. Here, it is preferable that the bottom frame (130) has a flat plate shape in which the gas cylinder can be accommodated. Here, the main body frame (100) may include at least one auxiliary frame so as to support the side of the gas cylinder at a certain height in the vertical direction from the bottom frame (130).

[0078] In addition, referring to FIGS. 9 and 10, the receiving space (110) is formed by a plurality of frames, and may be a storage space in which a space is formed inside to accommodate other items inside. The receiving space (110) is characterized in that it is arranged on the front side of the main body frame (100), and the remaining devices except for the gas tank are arranged inside the receiving space (110). The receiving space (110) may be in the form of a drawer or shelf having a predetermined size and height. In this case, the receiving space (110) may include at least one storage section from which items can be withdrawn laterally from the main body frame (100). In addition, the storage section may be configured in a form in which a certain space inside is divided into a shelf shape and a door is installed to enable withdrawal of items. However, a locking and fixing device is required for the door so that the storage section is not unnecessarily withdrawn when the main body frame (100) is moved. At this time, as illustrated in FIGS. 9 and 13, the outer surface of the storage unit may include a hook, and the hook is characterized in that the lid of the supply device can be hung and temporarily stored, or wiring or other devices can be temporarily hung and stored. In addition to the drawer type that can be pulled out, the drawer type that can open the door and load items inside, etc., as long as it is a drawer type that can load items into the internal space, it can be configured without limitation, and can be configured to be separated into a plurality of compartments as needed. Since the devices necessary for pipe removal are stored in the storage space (110), it is possible to quickly respond to problems that may arise during work by having a plurality of pieces of equipment, and there is an effect of preventing the loss of equipment.

[0079] Referring to Fig. 13, it is preferable that the receiving space (110) of the present invention include an empty space at the lower portion. In other words, an empty space is formed at the lower portion of the receiving space (110) to accommodate another device. This empty space may be formed by a leg component or the like capable of supporting the receiving portion. The present invention is characterized in that the recovery device (300) is custom-stored in the empty space and can be mounted and detached. This will be described in detail in the description of the recovery device (300) below.

[0080] At this time, it is preferable to store at least one of a measuring device that detects the magnetic force of a magnetic core (201) inserted into the pipe to be demolished and a cutter that cuts the pipe to be demolished in the receiving space (110). The measuring device is a device that identifies the magnetic core (201) inserted into the pipe to be demolished from the outside of the pipe, and includes a magnetic sensor that detects the magnetic force, and is characterized in that the magnetic sensor measures the magnetic force and determines whether the measured magnetic force is the magnetic force of the magnetic core (201) inserted into the pipe. It is preferable that the measuring device be configured as a device that can detect the degree of the intensity of the magnetic force detected by the magnetic sensor and distinguish whether this matches the intensity of the magnetic core (201). The cutter may be configured without limitation as long as it is a device that cuts the pipe identified by the measuring device in a direction perpendicular to the longitudinal direction of the pipe. In the present invention, the cutter may be a device configured integrally with the measuring device. In this case, the cutter may include a magnetic sensor, and the device may be configured to detect a magnetic core (201) inserted into the pipe by the magnetic sensor, and to operate the cutter when the magnetic core (201) is detected. It is preferable that the receiving space (110) accommodates other devices necessary for demolishing the pipe, including the measuring equipment and the cutter, without limitation.

[0081] The insertion device (200) is a device that inserts a magnetic core (201) into the interior of a pipe to be demolished. The insertion device (200) is preferably placed in a receiving space (110), and in the present invention, the insertion device (200) is characterized in that it is exposed and placed at the top of the receiving space (110). That is, when the receiving space (110) is in the form of a drawer, the insertion device (200) is exposed and placed on the upper surface thereof. In this case, the insertion device (200) is preferably fixed in position and coupled with the receiving space (110).

[0082] Referring to FIGS. 9 to 12, the insertion device (200) of the present invention is characterized by being a device that uses compressed gas to introduce a magnet core (201) into a pipe. Accordingly, the insertion device (200) includes a housing (210) that forms a sealed internal space, and an outlet formed on one side of the housing (210) to discharge the magnet core (201) to the outside of the housing (210) and introduce it into a pipe to be demolished. That is, the outlet is a portion connected to the pipe to be demolished. At this time, the insertion device (200) may further include a magnetic sensor that is located at the outlet and detects the magnetic force of the magnet core (201) that is withdrawn from the housing (210). The magnetic sensor is characterized by being capable of detecting the magnetic force of the magnet core (201) inserted into the pipe to be demolished, thereby measuring the length of the magnet core (201) inserted into the pipe.

[0083] In addition, the insertion device (200) includes a gas inlet (212) on the opposite side of the outlet (213), and the gas inlet (212) is connected to a gas tank, so that the compressed gas provided by the gas tank is injected into the housing (210), and the magnetic core (201) moves in the direction of travel along the outlet (213) and is inserted into the pipe. At this time, the gas inlet (212) may include a device that can control the pressure or flow rate of the supplied gas, and this may be a valve structure that can supply or stop the gas. At this time, the valve that can supply or stop the compressed gas may be installed manually or automatically. In addition, it is preferable that the gas tank further include a control device that can supply or stop the compressed gas contained therein, or control the supply pressure. The present invention has the effect of being able to insert a magnet core (201) using compressed gas, thereby minimizing damage to the magnet core (201) and stably inserting it all the way inside a long pipe while providing continuous traction. In addition, when the magnet core (201) is transported in the forward direction by the compressed gas, a plurality of transport rollers are rotated by power while being in close contact with the magnet core (201), thereby stably supplying the magnet core (201).

[0084] In addition, the insertion device (200) may have a structure including a magnet core bundle (220) that pulls out the wound magnet core (201) in the forward direction inside the housing (210), and a plurality of transport rollers that are in close contact with the magnet core (201) inside the housing (210) and rotate by power to transport the magnet core (201) in the forward direction. The plurality of transport rollers have an arrangement form so as to transport the magnet core (201) in the forward direction while maintaining tension, and may be configured so that the plurality of transport rollers can rotate at the same speed by a single motor. In addition, the insertion device (200) is characterized in that it further includes a magnetic sensor that is located at the discharge port (213) and detects the magnetic force of the magnet core (201) that is pulled out from the housing (210) and measures the length of the magnet core (201) inserted into the pipe.

[0085] In addition, the magnet core insertion device (200) of the present invention is configured to insert the magnet core (201) into a pipe having a long length or a predetermined diameter. At this time, the present invention is characterized by including a configuration that provides a traction force to the magnet core (201) to smoothly insert the magnet core (201) into a required position inside the pipe, regardless of the thickness of the wire (202) of the magnet core (201), the size of the magnet (203), the presence or absence of the guide ball (204), or the size of the guide ball (204).

[0086] FIG. 13 is a perspective view of a mobile magnetic core insertion and recovery system with a recovery device detached according to an embodiment of the present invention, FIG. 14 is a perspective view of a recovery device according to an embodiment of the present invention, and FIG. 15 is a side view of an independently movable recovery device according to an embodiment of the present invention. Referring to FIGS. 13 to 15, the recovery device (300) is characterized in that it is a device that can safely recover residues that may exist inside a pipe to be demolished during a pipe demolition work. At this time, the recovery device (300) is arranged at one end of the pipe to be demolished so that one end of the magnet core (201) inserted inside the pipe to be demolished reaches it, and when it is confirmed that the magnet core (201) reaches the recovery device (300), the supply of the magnet core (201) of the insertion device can be stopped. However, since the pipe to be demolished may have transported a fluid containing hazardous substances, the magnetic core (201) must be inserted and the pipe must be demolished without leaking the hazardous fluid remaining inside the pipe. Accordingly, the recovery device (300) of the present invention is characterized by having a chamber (310) structure in which the internal space is formed in a sealed manner. That is, the recovery device (300) is characterized by being a device that can safely discharge to the outside any residue existing inside the pipe to be demolished when the insertion device (200) supplies the magnetic core (201) into the pipe, and seal and store it for disposal. However, since the chamber (310) may generate a loud noise due to the recovery of the magnetic core (201) in a sealed space, the chamber (310) is characterized by being equipped with a silencer that reduces noise caused by the flow rate. The silencer is preferably installed inside the chamber (310), and can reduce not only noise but also the diffusion of the fluid.

[0087] The recovery device (300) is connected to the end of the pipe to be demolished and includes a recovery port (340) that guides and recovers residues including harmful gases remaining inside the pipe into the chamber (310). At this time, it is preferable that the recovery port (340) be structured so that the residues can be recovered while maintaining a seal so that the fluid inside the connected pipe to be demolished does not leak when the residues are recovered. Accordingly, referring to FIGS. 14 and 15, when one end of the pipe to be demolished is connected to the discharge port (213) of the insertion device, the other end is connected to the recovery port (340) of the recovery device (300), and the compressed gas supplied to one end of the pipe pushes the magnetic core (201) so that the residues are recovered to the recovery device (300) through the recovery port (340) together with the fluid inside. The above recovery port (340) is formed by protruding from the outer surface of the chamber (310), and preferably has a diameter that can accommodate the pipe to be demolished.

[0088] Referring to FIGS. 14 and 15, the recovery device (300) is characterized by including an exhaust unit (350) capable of exhausting gas recovered inside a chamber (310) together with a magnet core (201). When the chamber (310) is recovered, a fluid including gas and liquid inside the pipe is recovered together, and the gas is exhausted through the exhaust unit (350) and the liquid can be stored inside the chamber (310). At this time, the exhaust unit (350) may be configured as an exhaust damper as an exhaust device. The exhaust unit (350) may be connected to an external purification device, and the exhaust unit (350) may be configured to connect the inside of the chamber (310) and the purification device.

[0089] In addition, referring to FIG. 15, the recovery device (300) is characterized by including a drain valve (360) that can drain the liquid recovered inside the chamber (310) together with the magnetic core (201). The chamber (310) stores the fluid including gas and liquid inside the pipe together when recovering, and when the work is completed, the drain valve (360) can be opened to drain the liquid remaining in the chamber (310) to the outside. The drain valve (360) can be connected to an external purification device, and the drain valve (360) can be configured to connect the inside of the chamber (310) and the purification device.

[0090] The recovery device (300) may include a Hall sensor that detects magnetic force. The Hall sensor may detect that the magnet core (201) supplied from one side of the pipe to be demolished has reached the other side of the pipe and has reached the recovery device (300). Accordingly, when the magnet core (201) reaches the recovery device (300) and detects magnetic force, the power of the insertion device may be cut off or the supply of compressed gas may be cut off, thereby stopping the supply of the magnet core (201).

[0091] Referring to FIGS. 13 and 15, the recovery device (300) of the present invention is characterized in that it is formed to be attachable and detachable from the receiving space (110). Since the recovery device (300) can be separated from the main body frame and used independently, there is an effect in that the work can be smoothly performed without environmental restrictions during the pipe demolition work. Referring to FIG. 13, an empty space is formed at the lower part of the receiving space (110), and the size of the empty space and the recovery device (300) correspond to each other, so that the recovery device (300) can be mounted in the empty space. Here, the recovery device (300) can be used without limitation as long as it has a structure that can be coupled to the empty space.

[0092] As an embodiment of the present invention, referring to FIG. 13, a protrusion is formed in the empty space of the receiving space (110), and the recovery device (300) may have a structure in which a fitting part that engages with the protrusion is formed, such that the protrusion and the fitting part are engaged and mounted or detached. Here, the recovery device (300) is a chamber (310), and the chamber (310) has a rectangular shape in which one direction is longer, and the longer direction is referred to as the longitudinal direction. The longitudinal direction of the recovery device (300) may be formed along a direction penetrating the side surface of the main body frame. That is, the width portion of the main body frame corresponds to the longitudinal direction of the recovery device and is characterized in that it is mounted and detached. The length of the chamber (310) may be smaller than, equal to, or greater than the length of the empty space, and may be formed to be smaller than the length of the empty space for stable mounting so that all possible configurations of the recovery device (300) are located within the area of ​​the main body frame. However, the length of the handle (330) may protrude a certain length outside the main body frame.

[0093] Referring to Fig. 15, the recovery device (300) is characterized in that it can move independently when detached from the receiving space (110). Accordingly, the recovery device (300) includes at least one recovery device wheel (320) that enables the recovery device (300) to move independently. In addition, when the recovery device (300) moves independently, the recovery device (300) may further include a handle (330) so that a user can hold the recovery device (300) and push or pull it to adjust the direction. At this time, the handle (330) may be formed to extend from one side of the chamber (310), and the extended direction may be upward with respect to the moving recovery device (300). The handle (330) may have a structure that can be adjusted in length by increasing or decreasing in length along the extension direction.

[0094] Referring to FIGS. 13 to 15, the recovery device (300) is characterized in that it includes at least one recovery device wheel (320) on one side of the chamber (310), and a handle (330) that extends upward and protrudes on the other side of the chamber (310). The one side is characterized in that it is a bottom surface facing the ground when the recovery device (300) is mounted in the receiving space (110). In other words, it is characterized in that the recovery device wheel (320) is formed on one side of the wide surface of the chamber (310), and the handle (330) is arranged on the other side. In addition, it is preferable that the direction in which the handle (330) protrudes is along the longitudinal direction of the chamber (310). That is, when the recovery device (300) is detached and moves independently, the recovery device wheel (320) on one side touches the ground while the handle (330) on the other side is positioned upward and can be moved. In addition, when the recovery device (300) is mounted in the receiving space (110), the recovery device wheel (320) of the chamber (310) is arranged on the floor surface in the same plane as the frame wheel (140) of the main body frame, and the handle (330) of the chamber (310) is arranged to protrude from the side of the main body frame. Here, when the main body frame is moved, the recovery device wheel (320) of the chamber (310) can be installed at a higher position from the ground than the frame wheel (140) of the main body frame so that the recovery device wheel (320) of the chamber (310) does not touch the ground. Accordingly, when the recovery device (300) is mounted in the receiving space (110), the recovery device wheel (320) of the chamber (310) does not touch the ground. In addition, the recovery device (300) may have a recovery port (340) and an exhaust port (350) arranged on the upper surface of the chamber (310) based on the upper direction in which the handle (330) protrudes. That is, when the recovery device (300) moves independently, the direction of the handle (330) and the recovery port (340) and the exhaust port (350) are formed to protrude in parallel directions.In addition, the recovery device (300) may have a drain valve (360) positioned on one surface where the recovery device wheel (320) of the recovery device (300) is formed. That is, the drain valve (360) may be directed toward the ground and discharged. In addition, the upper surface of the chamber (310) may include an inspection hole through which the interior of the chamber (310) can be observed.
