Description

Technical Field

[0001] This invention relates to the field of nondestructive testing equipment technology, and in particular to a detachable corrosion flux leakage detector and a disassembly and handling method. Background Technology

[0002] The most common method for detecting corrosion on the bottom plate of storage tanks is to use a magnetic flux leakage (MFL) scanner. Currently, MFL scanners on the market typically weigh around 40-50 kg and are approximately 100 mm in size. 35 Approximately 50 cm; to ensure the safety of the equipment during transportation, it is usually equipped with a high-strength, shockproof, and waterproof transport box. The weight of the transport box is generally around 15-20 kg, and the size is generally 120 cm. 55 Approximately 70 centimeters in diameter; the weight and size of the entire set of equipment, including the transport box, make it no easy task for East Asians to move or transport, whether by hand or by foot. A regular passenger van wouldn't fit it, and it typically requires four strong laborers to lift it, with each person bearing over 15 kilograms. The testing work is already arduous, and the harsh environment, including high temperatures and potentially toxic substances, adds to the challenge. Due to on-site safety requirements, each testing personnel must wear anti-static long-sleeved shirts and trousers, a safety helmet, and safety shoes. After completing the day's testing, moving such heavy equipment becomes even more difficult.

[0003] In addition, the tank area is a flammable and explosive hazardous area, and is equipped with firewalls, which are generally about 1.2 meters high. Vehicles transporting equipment are not allowed to enter the firewalls, and even if they are allowed to enter, they cannot drive into the interior area of ​​the firewall without removing a portion of the 1.2-meter-high firewall.

[0004] Therefore, when inspecting for corrosion on the bottom plate of a storage tank, the inspectors must first move the heavy magnetic flux leakage scanner from outside the tank area to the inside of the firewall, and then move the equipment to the vicinity of the manhole of the oil tank. During this process, the inspectors sometimes have to carry the equipment across the oil pipeline inside the firewall, and then move the scanner through the manhole into the oil tank before they can begin the inspection work. The size of the manhole of the storage tank is usually 50 to 60 centimeters in diameter, which is not very convenient for inspectors to enter and exit, let alone move such a heavy set of magnetic flux leakage scanners.

[0005] Designing a detachable corrosion magnetic flux leakage detector and a disassembly and transportation method to make moving and transport more convenient, greatly reduce the labor intensity of testing personnel, facilitate quick and easy disassembly and assembly, and improve inspection efficiency has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a detachable corrosion magnetic flux leakage detector and a disassembly and handling method, and to solve the problems listed in the background art.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a detachable corrosion magnetic flux leakage detector scanner, comprising a main unit, a magnetic base and a hydraulic rod. Vertical plates are installed on both sides of the lower end of the main unit, and the vertical plates are provided with a first fixing through hole and a second screw hole.

The hydraulic rod upper end fixing seat is hinged to the hydraulic rod by a second hand-tightening screw. The end seat at the lower end of the hydraulic rod is hinged to the rear shaft of the magnetic base. Furthermore, when the host is placed on the magnetic base, the outer edge of the first fixing through hole rests on the centering bracket; The magnetic base is placed on the transport dock.

[0008] Preferably, it also includes a main unit rear wheel frame and a first walking wheel, one end of which is hinged to the first walking wheel, and the diameter of the first walking wheel is 80mm; A second fixing through hole is provided at the other end of the main unit's rear wheel frame, and a first screw hole is provided in the middle of the main unit's rear wheel frame; When the host is detached from the magnetic base, the first fixing through hole is connected to the first screw hole, and the second screw hole is connected to the second fixing through hole.

[0009] Preferably, a motor is installed at the lower end of the main unit, and the working end of the motor is connected to the first walking wheel via a transmission. Handle fixing plates are rotatably mounted on both side walls at the upper end of the main unit. Each handle fixing plate is equipped with a heightening block, which is fixedly connected to the hand rotating plate. Each hand rotating plate is fixedly connected to the upper handle.

[0010] Preferably, two neodymium iron boron permanent magnets are mounted on the bottom of the magnetic base via the side plate, and the two neodymium iron boron permanent magnets are each 300 mm in size. 30 9mm and 300 40 9mm; The front and rear ends of the side plate are respectively equipped with front wheels and rear wheels via the front axle and the rear axle.

[0011] Preferably, the center of the first hand-tightening screw has an 8mm internal hexagonal screw hole.

[0012] Preferably, the transport dock includes an aluminum alloy pallet, and second wheels are installed at the four corners of the lower surface of the aluminum alloy pallet, and the diameter of the second wheels is 75mm. The aluminum alloy pallet has arc-shaped grooves installed at the four corners of its upper surface, and transport fixing rods are installed on the two opposite side walls of the upper surface of the aluminum alloy pallet, with handles fixedly installed on the transport fixing rods. A traction rod is also hinged to the upper surface of the aluminum alloy pallet.

[0013] Preferably, the size of the arc-shaped groove corresponds to the size of the front wheel and the rear wheel.

[0014] Preferably, when the magnetic base is placed on the transport dock, the front wheel and the rear wheel are placed in the arc-shaped groove; The transport fixing screw is installed on the fixing screw hole, and the shank of the transport fixing screw has a groove. The two parallel transport fixing rods are connected to the binding straps, and the middle part of the binding straps abuts against the groove on the transport fixing screws.

[0015] A method for disassembling and transporting a detachable corrosion magnetic flux leakage detector includes the following steps: To reduce size and weight, the scanner can be quickly disassembled into two parts, the main unit and the magnetic base, for transportation or handling. S1. Remove the two first-tight screws on the left and right vertical plates that fix the main unit; S2. Remove the second hand-tightening screw that fixes the upper part of the hydraulic rod; S3. Disconnect the signal cable between the main unit and the magnetic base to separate the main unit and the magnetic base, and then pack and transport them separately. S4. After the main unit is separated from the magnetic base, the main unit is transported as follows: Install a rear wheel frame on each of the two vertical plates of the main unit. Concentrically fix the screw holes on the rear wheel frame with the first fixing through hole on the vertical plate. Concentrically fix the second screw hole on the vertical plate with the first fixing through hole on the wheel frame. Then install a first traveling wheel on each rear wheel frame. After the first traveling wheel is installed, the scanner's standing position is exactly the same as before the magnetic base is removed. This allows the main unit to stand upright, so the inspection personnel do not need to bend over or move it. It can be dragged upright or driven by a motor. S5. After the main unit is separated from the magnetic base, the magnetic base is transported as follows: Lift the entire magnetic base and place it on the transport dock. Align the rear and front wheels of the magnetic base with the arc-shaped grooves on the aluminum alloy pallet, ensuring that the rear and front wheels are fully engaged with the arc-shaped grooves for positioning. Then, screw a transport fixing screw into the fixing screw holes on the left and right side plates of the magnetic base. The handle of the transport screw has a groove. Finally, pass the two binding straps over the left and right transport fixing screws and the transport fixing rod respectively, and tighten the binding straps. S6. After arriving at the testing site, quickly reassemble the main unit and magnetic base by reversing the disassembly steps. During assembly, make sure to place the outer edge of the first fixing through hole on the left and right vertical plates of the main unit on the centering bracket so that the first fixing through hole is fully aligned with the fixing screw hole on the side plate. Tighten the two first hand-tightening screws on the left and right, and fix the upper end of the hydraulic rod to the upper end fixing seat of the hydraulic rod with the second hand-tightening screw. Plug in the relevant signal wires to complete the assembly.

[0020] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] like Figure 1-14 As shown, a detachable corrosion magnetic flux leakage detector includes a main unit 1, a magnetic base 2 and a hydraulic rod 12. Vertical plates 6 are installed on both sides of the lower end of the main unit 1. The vertical plates 6 are provided with a first fixing through hole 7 and a second screw hole 34. The magnetic base 2 has side plates 8 on both sides, and the side plates 8 have fixing screw holes 9. The first fixing through hole 7 is fixedly connected to the fixing screw hole 9 by the first hand-tightening screw 10. The outer side wall of the side plate 8 is equipped with a centering bracket 19. The center of the arc part of the centering bracket 19 is concentric with the first fixing through hole 7 on the vertical plate 6, and its diameter is the same as the outer diameter of the first fixing through hole 7. Therefore, when installing the main unit 1, it is only necessary to place the outer edge of the first fixing through hole 7 on the centering bracket 19, and the two first hand-tightening screws 10 can be easily screwed in. Similarly, when removing the first hand-tightening screws 10, since the main unit 1 is supported by the centering bracket 19, there is no need to worry about the main unit 1 falling off the magnetic base because the first hand-tightening screws 10 on both sides have been removed. A hydraulic rod upper end fixing seat 11 is installed in the middle of the rear side of the main unit 1. The hydraulic rod upper end fixing seat 11 is hinged to the hydraulic rod 12 by a second hand-tightening screw 13. The end seat 15 at the lower end of the hydraulic rod 12 is hinged to the rear shaft 14 of the magnetic base 2. Handle fixing plates 32 are rotatably mounted on the two side walls at the upper end of the main unit 1. Each handle fixing plate 32 is equipped with a heightening block 31. The heightening block 31 is fixedly connected to the hand rotating plate 30. Each hand rotating plate 30 is fixedly connected to the upper handle 16. When loading the main unit 1 into the transport box, the upper left and right handles 16 of the scanner are shaped like outwards, and their width exceeds the width of the main unit 1. This increases the width of the transport box, making it inconvenient to transport. The upper handle 16 can be detachably and 180-degree adjustable to the main unit via a threaded connection. When entering or exiting the manhole of the storage tank or packing, the upper handle 16 can be removed or adjusted to a suitable angle. The upper handle 16 is very easy to remove. Simply remove the three fixing screws on the handle rotating plate 30 to remove the handle rotating plate 30 and the upper handle 16 together. Alternatively, the upper handle 16 can be unscrewed off separately for easy handling and transportation. In addition, during the use of the scanner, pressure needs to be applied to the upper handle 16 multiple times in order to lift the front wheel 18 to adjust the direction or change the detection position. When pressure is applied downward to the upper handle 16, the hand gripping the handle will also generate a rotational force. The rotational force of the upper handle 16 on the left is clockwise, and the rotational force of the upper handle 16 on the right is counterclockwise. The threads of the upper handles 16 on both sides are designed to be reverse-threaded to avoid loosening and abnormal noise during use. Instead, they become tighter with use. Furthermore, the scanner's height is suitable for testing personnel under 175 cm tall. For testing personnel over 175 cm tall, a 5 cm high height-increasing block 31 is added between the handle fixing plate 32 and the handle rotating plate 30, raising the upper handle 16 by 5 cm, making the scanner suitable for most people of most heights.

[0022] Two neodymium iron boron permanent magnets 21 are mounted on the bottom of the magnetic base 2 via the side plate 8. The dimensions of the two neodymium iron boron permanent magnets 21 are 300X30X9mm and 300X40X9mm, respectively. The front and rear ends of the side plate 8 are respectively equipped with a front wheel 18 and a rear wheel 17 via the front axle and the rear axle 14; The contact points of the main unit 1, magnetic base 2, and hydraulic rod 12 form a stable triangular structure. The hydraulic rod 12, acting as a lever, plays a crucial role in lifting the magnetic base 2 from the tank bottom plate during the scanning process. Additionally, the hydraulic rod 12 has two other functions: First, it acts as a buffer when the magnetic base 2 is lifted by the handle 16 on the upper part of the main unit 1, transforming the rigid rod into a cushioned one, preventing impact and injury to the operator's wrists regardless of the force applied. Second, utilizing the action and reaction principle of the hydraulic rod, it transmits the force applied by the operator, allowing the rear wheel 17 of the magnetic base 2 to act as a fulcrum, lifting the front wheel 18 away from the tank bottom plate. This allows only the rear wheel 17 to remain on the ground, enabling flexible operation of the scanner for forward, backward, and turning movements, as well as changing the scanned position. Furthermore, when the host 1 is placed on the magnetic base 2, the outer edge of the first fixing through hole 7 is placed on the centering bracket 19; The magnetic base 2 is placed on the transport dock 3.

[0023] Specifically, it also includes the main unit's rear wheel frame 4 and the first wheel 5. One end of the main unit's rear wheel frame 4 is hinged to the first wheel 5, and the diameter of the first wheel 5 is 80mm, which has a strong crossing ability and can pass through the weld seams on the bottom plate of the storage tank or the pits and depressions on the ground outside the storage tank. The other end of the main unit's rear wheel frame 4 is provided with a second fixing through hole 35, and the middle part of the main unit's rear wheel frame 4 is provided with a first screw hole 33. When the host 1 is detached from the magnetic base 2, the first fixing through hole 7 is connected to the first screw hole 33, the second screw hole 34 is connected to the second fixing through hole 35, and a motor 20 is installed at the lower end of the host 1. The working end of the motor 20 is connected to the first walking wheel 5 for transmission. After the first traveling wheel 5 is installed, the scanner's standing position remains exactly the same as before the magnetic base 2 was removed. This allows the main unit 1 to stand upright, eliminating the need for the inspector to bend over or move it. The operator can simply push the main unit 1 upright or have it driven by the motor 20.

[0024] Specifically, since the inside of the storage tank may not be completely cleaned, there may be a lot of dust. After several hours or days of inspection, dust may get into the threads of the first hand-tightening screw 10. In this case, it may be very difficult to remove the first hand-tightening screw 10 manually, and sometimes it is impossible to remove the first hand-tightening screw 10 by hand. To solve this problem, an 8mm internal hexagonal screw hole is made in the center of the first hand-tightening screw 10. The first hand-tightening screw 10 can be easily removed with an 8mm internal hexagonal wrench, so that the main unit 1 can be separated from the magnetic base 2.

[0025] Specifically, the transport dock 3 includes an aluminum alloy pallet 22, and second wheels 25 are installed at the four corners of the lower surface of the aluminum alloy pallet 22, and the diameter of the second wheels 25 is 75mm. The aluminum alloy pallet 22 has arc-shaped grooves 29 installed at the four corners of its upper surface. Transport fixing rods 26 are installed opposite each other on the two sidewalls of the upper surface of the aluminum alloy pallet 22. A handle 23 is fixedly installed on the transport fixing rod 26. Including the thickness of the aluminum alloy pallet 22, the total thickness is 95mm. This ensures that the distance between the neodymium iron boron permanent magnet 21 on the magnetic base 2 and the ground reaches 95mm, guaranteeing that the distance between the neodymium iron boron permanent magnet 21 and other objects it comes into contact with is at least 95mm. This achieves effective and reliable magnetic isolation, preventing the neodymium iron boron permanent magnet 21 from adsorbing onto magnetic objects. Furthermore, once the neodymium iron boron permanent magnet 21 is attracted to the bottom plate or wall of the storage tank, it is impossible to remove it from the attracted tank bottom or wall without reassembling the main unit 1 and the magnetic base 2. Moreover, during transportation, without magnetic isolation treatment, the neodymium iron boron permanent magnet 21 may also adhere to the bottom plate of the transport vehicle. The upper surface of the aluminum alloy pallet 22 is also hinged with a traction rod 24. The traction rod 24 can be spliced ​​into three sections, with a total spliced ​​length of 1.2 meters. This makes it easier for the inspection personnel to pull while standing. When placing the equipment into the transport box, there is no need to remove the magnetic base 2 from the transport dock 3. They can be directly loaded into the transport box together. When the transport dock 3 is not equipped with the traction rod 24, it can be safely carried or lifted by the two handles 23 on the left and right.

[0026] Specifically, the dimensions of the arc-shaped groove 29 correspond to the dimensions of the front wheel 18 and the rear wheel 17.

[0027] Specifically, when the magnetic base 2 is placed on the transport dock 3, the front wheel 18 and the rear wheel 17 are placed in the arc-shaped groove 29, so that the magnetic base plate 2 can be placed stably on the transport dock 3. The fixed screw 27 is installed on the fixed screw hole 9, and the shank of the fixed screw 27 has a groove to prevent the binding strap 28 from falling off the fixed screw 27 when binding. The two parallel transport fixing rods 26 are connected to the binding straps 28, and the middle part of the binding straps 28 abuts against the groove on the transport fixing screws 27. This ensures that the magnetic base 2 and the transport dock 3 are integrated, so that the magnetic base 2 will not fall off the transport dock 3 during transportation, regardless of bumps or tumbling.

[0028] A method for disassembling and transporting a detachable corrosion magnetic flux leakage detector includes the following steps: To reduce size and weight, the scanner can be quickly disassembled into two parts, the main unit 1 and the magnetic base 2, during transportation or handling. S1. Remove the two first-tightening screws 10 on the left and right vertical plates 6 of the main unit 1; S2. Remove the second hand-tightening screw 13 that is fixed to the upper part of the hydraulic rod 12; S3. Disconnect the signal cable between the main unit 1 and the magnetic base 2 to separate the main unit 1 and the magnetic base 2, and then pack and transport them separately. S4. After the main unit is separated from the magnetic base, the main unit is transported as follows: Install one main unit walking rear wheel frame 4 on each of the two vertical plates 6 of the main unit 1. Concentrically fix the screw hole 33 on the main unit walking rear wheel frame 4 with the first fixing through hole 7 on the vertical plate. Concentrically fix the second screw hole 34 on the vertical plate with the first fixing through hole 7 on the wheel frame. Then install one first walking wheel 5 on each main unit walking rear wheel frame 4. The standing position of the scanner after the first walking wheel 5 is installed is exactly the same as before the magnetic base 2 is removed. In this way, the main unit 1 can be in a standing position. The inspection personnel do not need to bend over or move it. It can be dragged upright or driven by the motor 20. S5. After the main unit is separated from the magnetic base, the magnetic base is transported as follows: Lift the magnetic base 2 as a whole and place it on the transport dock 3. Align the rear wheel 17 and front wheel 18 of the magnetic base 2 with the arc-shaped groove 29 on the aluminum alloy support plate 22, so that the rear wheel 17 and front wheel 18 are completely in contact with the arc-shaped groove 29 for positioning. Then, screw a transport fixing screw 27 into the fixing screw holes 9 on the left and right side plates 8 of the magnetic base 2. The handle of the transport screw 27 has a groove. Finally, pass the two binding straps 28 over the left and right two transport fixing screws 27 and the transport fixing rod 26 respectively, and tighten the binding straps 28. S6. After arriving at the testing site, quickly reassemble the main unit 1 and the magnetic base 2 by reversing the disassembly steps. During assembly, make sure to place the outer edge of the first fixing through hole 7 on the left and right vertical plates 6 of the main unit 1 on the centering bracket 19 so that the first fixing through hole 7 is fully aligned with the fixing screw hole 9 on the side plate 8. Tighten the two first hand-tightening screws 10 on the left and right, and fix the upper end of the hydraulic rod 12 to the upper end fixing seat 11 of the hydraulic rod through the second hand-tightening screw 13. Plug in the relevant signal wires to complete the assembly work.

S1. Remove the two first-hand screws (10) on the left and right vertical plates (6) of the main unit (1). S2. Remove the second hand-tightening screw (13) that is fixed on the upper part of the hydraulic rod (12); S3. Disconnect the signal cable between the main unit (1) and the magnetic base (2) to separate the main unit (1) and the magnetic base (2), and then pack and transport them separately. S4. After the main unit is separated from the magnetic base, the main unit is transported as follows: Install one main unit walking rear wheel frame (4) on each of the two vertical plates (6) of the main unit (1). Concentrically fix the screw hole (33) on the main unit walking rear wheel frame (4) with the first fixing through hole (7) on the vertical plate. Concentrically fix the second screw hole (34) on the vertical plate with the first fixing through hole (7) on the wheel frame. Then install one first walking wheel (5) on each main unit walking rear wheel frame (4). The standing state of the scanner after the first walking wheel (5) is installed is exactly the same as before the magnetic base (2) is removed. In this way, the main unit (1) can be in a standing state. The inspection personnel do not need to bend over and move it. It can be dragged upright or driven by the motor (20). S5. After the main unit is separated from the magnetic base, the magnetic base is transported as follows: Lift the magnetic base (2) as a whole and place it on the transport dock (3). Align the rear wheel (17) and front wheel (18) of the magnetic base (2) with the arc-shaped groove (29) on the aluminum alloy tray (22) so that the rear wheel (17) and front wheel (18) fit perfectly with the arc-shaped groove (29) for positioning. Then, screw a transport fixing screw (27) into the fixing screw hole (9) on the left and right side plates (8) of the magnetic base (2). The handle of the transport screw (27) has a groove. Finally, pass the two binding straps (28) over the left and right two transport fixing screws (27) and the transport fixing rod (26) respectively, and tighten the binding straps (28). S6. After arriving at the testing site, quickly reassemble the main unit (1) and the magnetic base (2) by reversing the disassembly steps. During assembly, pay attention to placing the outer edge of the first fixed through hole (7) on the left and right vertical plates (6) of the main unit (1) on the centering bracket (19) so that the first fixed through hole (7) is fully aligned with the fixed screw hole (9) on the side plate (8). Tighten the two first hand-tightening screws (10) on the left and right, and fix the upper end of the hydraulic rod (12) to the upper end fixing seat (11) of the hydraulic rod through the second hand-tightening screw (13). Plug in the relevant signal wires to complete the assembly work.
