Description

Technical Field

[0001] This utility model relates to the technical field of permanent demagnetization devices, and in particular to a portable permanent demagnetization device for pipelines. Background Technology

[0002] A permanent demagnetizing device is used to demagnetize pipes. When using it, the device is moved to a suitable position using casters evenly spaced at the bottom of the base, making it easy to carry. The device is then energized via a connecting wire, which in turn energizes the coil inside. When the coil is energized, an alternating magnetic field is generated at its geometric center. The direction and intensity of this magnetic field change with the current. This alternating magnetic field disrupts the magnetic domain arrangement within the object, causing it to gradually lose its magnetism. The pipe is placed on top of an arc-shaped plate, supported by a first spring. The pipe is then manually slid along the inner wall of the device, effectively demagnetizing the pipe.

[0003] The inventors discovered in their daily work that the permanent demagnetizing device still has at least the following problems: When using the permanent demagnetizing device, the main body of the demagnetizing device is moved to a suitable position by the universal wheels evenly distributed at the bottom of the base. Then, the main body of the demagnetizing device is energized through the connecting wire, which in turn energizes the coil inside the main body of the demagnetizing device. When the coil is energized, an alternating magnetic field is formed at its geometric center. The direction and intensity of this magnetic field change continuously with the change of current. The alternating magnetic field can disrupt the magnetic domain arrangement inside the object, causing it to gradually lose its magnetism. Placing the pipe on top of the arc plate and supporting the arc plate with the first spring, and then manually controlling the pipe to slide on the inner wall of the demagnetizing device, can effectively demagnetize the pipe. However, in actual use, in order to improve the portability of the demagnetizing device, its weight is relatively small. This makes it possible for the main body of the demagnetizing device to tip over when the pipe passes through the inside of the demagnetizing device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a portable permanent demagnetizing device for pipelines.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a portable pipe permanent demagnetizing device, comprising a demagnetizing device body, a coil disposed inside the demagnetizing device body, a first damping rod fixedly connected to the bottom of the inner wall of the demagnetizing device body, an arc plate fixedly connected to the top of the first damping rod, a first spring sleeved on the surface of the first damping rod, the bottom of the first spring fixedly connected to the bottom of the inner wall of the demagnetizing device body, one end of the first spring near the first damping rod fixedly connected to the bottom of the arc plate, a base fixedly connected to the bottom of the demagnetizing device body, and one side of the demagnetizing device body... A connecting line is provided. A support device is provided on one side of the base. A storage device is provided on one side of the demagnetizing device body. Universal wheels are evenly installed on the bottom of the base. The support device includes a support block. The support block is fixedly connected to one side of the base. A round rod is rotatably inserted through one side of the support block. Rotating blocks are fixedly connected to both ends of the round rod. A rotating strip is fixedly connected to one side of the rotating block. A movable frame is slidably fitted on the surface of the rotating strip. A rotating rod is rotatably inserted between the two movable frames. A rectangular strip is fixedly connected to the surface of the rotating rod. A limit strip is provided between the support block and the rectangular strip.

[0006] The effect achieved by the above components is as follows: When using the support device, manually control the rotating block to drive the round rod to rotate to a suitable position, thereby causing the moving frame to slide to the end of the rotating bar away from the rotating block. Then, control the rectangular bar to drive the rotating rod to rotate, so that one side of the rectangular bar is placed on the ground, pressing the limiting bar into the middle of the rectangular bar and the support block. This can effectively restrict the moving frame to the surface of the rotating bar, and thus place one side of the rectangular bar on the ground, which can support the demagnetizing device to a certain extent.

[0007] Preferably, the limiting strip has a locking groove on both sides, and a rubber plate is fixedly connected to one side of the rectangular strip and the support block, with the rubber plate disposed inside the locking groove.

[0008] The effect achieved by the above components is to squeeze the rubber plate into the slot, so that the limiting strip can be set on one side of the rectangular strip and the support block.

[0009] Preferably, a baffle is fixedly connected to one side of both the rectangular strip and the support block, and the baffle is disposed on one side of the rubber plate.

[0010] The effect achieved by the above components is that the baffle is set on the side of the limiting strip away from the support block and the rectangular strip, which can prevent the limiting strip from moving on the side of the support block and the rectangular strip to a certain extent.

[0011] Preferably, a storage groove is provided on one side of the support block, and rubber blocks are uniformly fixedly connected to the inner wall of the storage groove, with the rubber blocks disposed inside the slot.

[0012] The effect achieved by the above components is that when the support device is not used, the limiting strip can be manually slid into the storage groove, thereby squeezing the rubber block into the locking groove, which makes it easier to restrict the limiting strip inside the storage groove.

[0013] Preferably, the storage device includes fixed rollers, and two fixed rollers are evenly inserted on the side of the demagnetizing device body away from the connecting line.

[0014] The effect achieved by the above components is that when using the storage device, the connecting wire is wrapped around the top of the demagnetizing device body and then wound around the surface of the two fixed rollers, which can store the connecting wire to a certain extent.

[0015] Preferably, the top surface of the demagnetizing device body is uniformly and fixedly connected with locking rings.

[0016] The effect achieved by the above components is that the two locking rings are set on both sides of the connecting line, which makes it easier for the connecting line to slide on the top of the demagnetizing device body.

[0017] Preferably, a groove is provided on one side of the fixed roller, a limit rod is fixedly connected to the inner wall of the groove, an extrusion plate is slidably sleeved on the surface of the limit rod, and a second spring is fixedly connected to one side of the inner wall of the groove, with one end of the second spring near the limit rod and one side of the extrusion plate fixedly connected.

[0018] The effect achieved by the above components is that the extrusion plate is pulled towards the main body of the demagnetizing device by the second spring, thereby causing the extrusion plate to be pressed against the surface of the connecting line, which can effectively limit it to the surface of the fixed roller.

[0019] Preferably, a second damping rod is fixedly connected to the end of the demagnetizing device body away from the connecting line, and a rectangular sleeve is fixedly connected to the end of the second damping rod away from the demagnetizing device body. A third spring is sleeved on the surface of the second damping rod, one side of the third spring is fixedly connected to one side of the demagnetizing device body, and the end of the third spring near the second damping rod is fixedly connected to one side of the rectangular sleeve. A connection port is opened at the top of the rectangular sleeve.

[0020] The effect achieved by the above components is as follows: the rectangular sleeve is pulled towards the main body of the demagnetizing device by the third spring, and then the rectangular sleeve is placed on the surface of the connecting line and the fixed roller, and then one end of the connecting line is slid into the inside of the connection port, which makes it easier to restrict the connecting line to one side of the main body of the demagnetizing device.

[0021] In this invention, by setting up a support device, when using the support device, the rotating block is manually controlled to drive the round rod to rotate to a suitable position, thereby causing the moving frame to slide to the end of the rotating bar away from the rotating block. Then, the rectangular bar is controlled to drive the rotating rod to rotate, so that one side of the rectangular bar is placed on the ground, pressing the limiting strip between the rectangular bar and the support block. This can effectively restrict the moving frame to the surface of the rotating bar, and thus place one side of the rectangular bar on the ground, which can support the demagnetizing device to a certain extent.

[0027] Example 1, such as Figure 1-4As shown, a portable permanent demagnetizing device for pipes includes a coil 2 inside the main body 1. A first damping rod 3 is fixedly connected to the bottom of the inner wall of the main body 1, and an arc plate 5 is fixedly connected to the top of the first damping rod 3. A first spring 4 is sleeved on the surface of the first damping rod 3, and the bottom of the first spring 4 is fixedly connected to the bottom of the inner wall of the main body 1. One end of the first spring 4 near the first damping rod 3 is fixedly connected to the bottom of the arc plate 5. A base 6 is fixedly connected to the bottom of the main body 1. A connecting wire 7 is provided on one side of the main body 1. A support device 8 is provided on one side of the base 6. A storage device 9 is provided on one side of the main body 1. Universal wheels 10 are evenly installed on the bottom of the base 6. When using the demagnetizing device, the main body 1 of the demagnetizing device is moved to a suitable position by the casters 10 evenly distributed at the bottom of the base 6, making the demagnetizing device easy to carry. Then, the main body 1 of the demagnetizing device is energized through the connecting wire 7, which in turn energizes the coil 2 inside the main body 1. When the coil 2 is energized, an alternating magnetic field is formed at its geometric center. The direction and intensity of this magnetic field change continuously with the change of current. The alternating magnetic field can disrupt the magnetic domain arrangement inside the object, causing it to gradually lose its magnetism. The pipe is placed on top of the arc plate 5, supported by the first spring 4. Then, the pipe is manually controlled to slide on the inner wall of the demagnetizing device, which can effectively demagnetize the pipe.

[0028] Reference Figure 2The support device 8 includes a support block 801, which is fixedly connected to one side of the base 6. A round rod 802 is rotatably inserted through one side of the support block 801. Rotating blocks 803 are fixedly connected to both ends of the round rod 802. A rotating strip 804 is fixedly connected to one side of the rotating block 803. A movable frame 805 is slidably fitted onto the surface of the rotating strip 804. A rotating rod 806 is rotatably inserted between the two movable frames 805. A rectangular strip 807 is fixedly connected to the surface of the rotating rod 806. A limit strip 810 is provided between the support block 801 and the rectangular strip 807. When the support device 8 is in operation, the rotating block 803 is manually controlled to drive the round rod 802 to rotate to a suitable position, thereby causing the moving frame 805 to slide to the end of the rotating bar 804 away from the rotating block 803. This then controls the rectangular bar 807 to drive the rotating rod 806 to rotate, so that one side of the rectangular bar 807 is placed on the ground, pressing the limiting strip 810 between the rectangular bar 807 and the support block 801. This effectively restricts the moving frame 805 to the surface of the rotating bar 804, and places one side of the rectangular bar 807 on the ground. This, to a certain extent, helps to control the demagnetization device. The limiting strip 810 is supported, and locking grooves 811 are provided on both sides. A rubber plate 809 is fixedly connected to one side of the rectangular strip 807 and the support block 801. The rubber plate 809 is located inside the locking groove 811. By pressing the rubber plate 809 into the locking groove 811, the limiting strip 810 can be positioned on one side of the rectangular strip 807 and the support block 801. A baffle 808 is fixedly connected to one side of the rectangular strip 807 and the support block 801. The baffle 808 is located on one side of the rubber plate 809, away from the limiting strip 810 and the support block 801. On one side of the support block 801 and the rectangular bar 807, the limiting bar 810 can be prevented from moving on one side of the support block 801 and the rectangular bar 807 to a certain extent. A storage groove 812 is provided on one side of the support block 801. Rubber blocks 813 are evenly fixedly connected to the inner wall of the storage groove 812. The rubber blocks 813 are set inside the locking groove 811. When the support device 8 is not used, the limiting bar 810 can be manually slid into the storage groove 812, thereby squeezing the rubber blocks 813 into the locking groove 811. This makes it easy to restrict the limiting bar 810 inside the storage groove 812.

[0029] Reference Figure 3 and Figure 4The storage device 9 includes two fixed rollers 902, which are evenly inserted on the side of the demagnetizing device body 1 away from the connecting wire 7. When using the storage device 9, the connecting wire 7 is wrapped around the top of the demagnetizing device body 1 and then wound around the surface of the two fixed rollers 902, which can store the connecting wire 7 to a certain extent. Two locking rings 901 are evenly fixedly connected to the top surface of the demagnetizing device body 1, with the two locking rings 901 positioned on both sides of the connecting wire 7, facilitating the sliding of the connecting wire 7 on the top of the demagnetizing device body 1. A groove 903 is provided on one side of the fixed rollers 902, and a limiting rod 904 is fixedly connected to the inner wall of the groove 903. A pressing plate 905 is slidably fitted onto the surface of the limiting rod 904. A second spring 906 is fixedly connected to one side of the inner wall of the groove 903, with one end of the second spring 906 near the limiting rod 904 and one side of the pressing plate 905. The second spring 906 pushes the wire closer to the demagnetizing device body 1... The extrusion plate 905 is pulled in a certain direction, causing it to press against the surface of the connecting line 7. This effectively confines the line to the surface of the fixed roller 902. A second damping rod 907 is fixedly connected to the end of the demagnetizing device body 1 away from the connecting line 7. A rectangular sleeve 909 is fixedly connected to the end of the second damping rod 907 away from the demagnetizing device body 1. A third spring 908 is fitted onto the surface of the second damping rod 907. One side of the third spring 908 is fixedly connected to one side of the demagnetizing device body 1. The end of the third spring 908 near the second damping rod 907 is fixedly connected to one side of the rectangular sleeve 909. A connection port 910 is provided at the top of the rectangular sleeve 909. By pulling the rectangular sleeve 909 towards the demagnetizing device body 1 through the third spring 908, the rectangular sleeve 909 is fitted onto the surface of the connecting line 7 and the fixed roller 902, thereby sliding one end of the connecting line 7 into the connection port 910. This facilitates confining the connecting line 7 to one side of the demagnetizing device body 1.

[0030] Working principle: When using the permanent demagnetizing device, the demagnetizing device body 1 is moved to a suitable position using the evenly distributed casters 10 at the bottom of the base 6 (the demagnetizing device body can be the RB Annis LGA-4 model; since it is a commercially available product, its specific working principle will not be elaborated here). This makes the demagnetizing device easy to carry. Then, the demagnetizing device body 1 is energized via the connecting wire 7, which in turn energizes the coil 2 inside the demagnetizing device body 1. When the coil 2 is energized, an alternating magnetic field is formed at its geometric center. The direction and intensity of this magnetic field change continuously with the change of current. The alternating magnetic field can disrupt the magnetic domain arrangement inside the object, causing it to gradually lose its magnetism. The pipe is placed on top of the arc plate 5, supported by the first spring 4. Then, the pipe is manually controlled to slide along the inner wall of the demagnetizing device. This effectively... To demagnetize the pipeline, when using the support device 8, manually control the rotating block 803 to drive the round rod 802 to a suitable position, thereby causing the moving frame 805 to slide to the end of the rotating bar 804 away from the rotating block 803. This then controls the rectangular bar 807 to drive the rotating rod 806 to rotate, so that one side of the rectangular bar 807 is placed on the ground, pressing the limiting strip 810 between the rectangular bar 807 and the support block 801, and pressing the rubber plate 809 into the slot 811. This allows the limiting strip 810 to be positioned on one side of the rectangular bar 807 and the support block 801, with the baffle 808 positioned on the side of the limiting strip 810 away from the support block 801 and the rectangular bar 807. To a certain extent, this prevents the limiting strip 810 from moving on one side of the support block 801 and the rectangular strip 807. This effectively restricts the moving frame 805 to the surface of the rotating strip 804, thus placing one side of the rectangular strip 807 on the ground. This provides some support for the demagnetizing device. When the support device 8 is not in use, the limiting strip 810 can be manually slid into the storage groove 812, thereby pressing the rubber block 813 into the locking groove 811. This facilitates the restriction of the limiting strip 810 within the storage groove 812. When using the storage device 9, the connecting wire 7 is routed around the top of the demagnetizing device body 1, with two locking rings 901 positioned on either side of the connecting wire 7 for easy connection. The wire 7 slides on the top of the demagnetizing device body 1, and then the connecting wire 7 is wound around the surface of the two fixed rollers 902. The second spring 906 pulls the extrusion plate 905 towards the demagnetizing device body 1, so that the extrusion plate 905 is pressed against the surface of the connecting wire 7. This can effectively restrict it on the surface of the fixed rollers 902. The third spring 908 pulls the rectangular sleeve 909 towards the demagnetizing device body 1, so that the rectangular sleeve 909 is fitted onto the surface of the connecting wire 7 and the fixed rollers 902, and then one end of the connecting wire 7 slides into the inside of the connection port 910. This makes it easier to restrict the connecting wire 7 to one side of the demagnetizing device body 1, so that the connecting wire 7 can be stored to a certain extent.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
