Description

Technical Field

[0001] The invention relates to the technical field of wire rope magnetization sensor detection, in particular to an intrinsically safe wire rope non-contact magnetization detection integrated device for mining. Background Art

[0002] The detection principle of the wire rope magnetization sensor is a detection method based on the magnetic leakage detection technology. The detection principle of the wire rope magnetization sensor is to detect and evaluate the internal defects of the wire rope by magnetizing the wire rope, using the magnetic leakage phenomenon, and capturing the leakage magnetic field through the sensor. This detection method has the advantages of high sensitivity, high resolution and real-time monitoring;

[0003] In the prior art, the steel wire rope magnetization sensor detection often uses an annular magnetic block to magnetize the steel wire rope. However, during the magnetization process, the steel wire rope needs to pass through the inside of the detector. It is troublesome for the steel wire rope to pass through the inside of the annular magnetizer. The annular magnetizer cannot be disassembled. If it is disassembled, the magnet will break, thereby affecting the magnetization of the steel wire rope. In addition, since the steel wire rope cannot be located in the middle of the magnetic pole or toward the edge, it is easy to cause the center of the intersection of the magnetic field to be inconsistent with the center of the steel wire rope, thereby affecting the result of the steel wire rope detection. Summary of the invention

[0004] The object of the present invention is to provide an integrated non-contact magnetization detection device for intrinsically safe steel wire ropes for use in mining, so as to solve the problems raised in the above-mentioned background technology.

The steel wire rope can be easily placed at any position of the steel wire rope, and the magnetic field of the permanent magnet can still magnetize the steel wire rope when closed;

[0016] An axis adjusting structure is provided to adjust the length of the screwed engagement between the fixing bolt and the threaded hole, so that the fixing frame is offset, and thus the position of the fixed wheel can be changed according to the diameter of the steel wire rope, so that the axis of the steel wire rope is located in the middle of the intermediate shield, ensuring that the influence of the magnetic field on the steel wire rope or the detection of the difference in the electronic structure of the steel wire rope is relatively consistent, and improving the accuracy of the magnetic sensor for detecting internal damage of the steel wire rope.

The center of the largest circle formed by the fixed wheel and the active wheel is aligned with the center line of the steel wire rope, and the steel wire rope can be initially positioned, reducing the occurrence of the situation where the steel wire rope contacts the intermediate shield;

[0018] Through the torsion spring of the clamping structure, the movable wheel is deflected under the action of the torsion spring, which can ensure that the fixed wheel and the movable wheel are in close contact, and change with the position of the fixed wheel, so that it is also suitable for clamping wire ropes of different diameters, and the detector will not fall off easily when it is moved;

[0019] The connection plate and the buckle cooperate with each other, and the limiting copper bar and the fixing groove cooperate with each other, so that the detector shell can be disassembled and assembled, thereby facilitating the placement of the steel wire rope into the interior of the detector and preventing the steel wire rope from falling off from the interior of the detector.

[0031] Embodiment 1:

[0032] See also Figure 1-Figure 8As shown, a non-contact magnetization detection integrated device for intrinsically safe steel wire rope for mining includes a first detector housing 1, a second detector housing 2, a first permanent magnet 13, a second permanent magnet 14 and two magnetic sensors 29, the first detector housing 1 and the second detector housing 2 are arranged in pairs, the first detector housing 1 and the second detector housing 2 are connected at the same side edge, the first detector housing 1 and the second detector housing 2 are connected by a hinge, so that the first detector housing 1 and the second detector housing 2 can be relatively unfolded or closed, the steel wire rope can be put into the middle of the detector when the first detector housing 1 and the second detector housing 2 are unfolded, and the steel wire rope can be clamped in the middle of the detector when the first detector housing 1 and the second detector housing 2 are closed, the first permanent magnet 13 is arranged inside the first detector housing 1, and the second permanent magnet 14 is arranged inside the second detector housing 2;The first permanent magnet 13 and the second permanent magnet 14 are arranged in parallel. The first permanent magnet 13 and the two first pole shoes 15 are arranged in a "U" shape. The second permanent magnet 14 and the second pole shoe 16 are arranged in a "U" shape. The first pole shoes 15 are provided at both ends of the first permanent magnet 13, and the second pole shoes 16 are provided at both ends of the second permanent magnet 14. The magnetic field directions of the first permanent magnet 13 and the second permanent magnet 14 are from the N pole to the S pole outside the magnet and from the S pole to the N pole inside the magnet. Thus, at the position of the steel wire rope, compared with the magnetic fields of the first permanent magnet 13 and the second permanent magnet 14, two magnetic sensors 29 are respectively arranged between the opposite surfaces of the first permanent magnet 13 and the second permanent magnet 14. The magnetic sensors 29 can sense the electronic direction of the steel wire rope. Coil skeletons 28 are provided between the ends of the two first pole shoes 15 and between the ends of the two second pole shoes 16. A first intermediate shield 3 is provided between the two coil skeletons 28 of the first pole shoe 15, and a second intermediate shield 4 is provided between the two coil skeletons 28 of the second pole shoe 16. The cross-sections of the first intermediate shield 3 and the second intermediate shield 4 are annular. The first pole shoes 15 at both ends of the first permanent magnet 13 direct the magnetic field. Similarly, the second pole shoes 16 at both ends of the second permanent magnet 14 direct the magnetic field. And the two magnetic sensors 29 are respectively arranged on the opposite surfaces of the first intermediate shield 3 and the second intermediate shield 4, so as to sense the electrons of the steel wire rope. The inner wall of the first detector housing 1 is provided with a limiting copper bar 11. The limiting copper bar 11 is installed inside the first detector housing 1. A fixing groove 12 is formed in the side wall of the limiting copper bar 11. The limiting copper bar 11 can clamp the first intermediate shield 3 and the second intermediate shield 4. Axis adjustment structures for adjusting the axial position of the steel wire rope are provided at both ends of the first detector housing 1. Clamping structures for clamping the steel wire rope are provided at both ends of the second detector housing 2. The axis adjustment structures and the clamping structures are arranged in pairs. The steel wire rope passes through the interiors of the first detector housing 1 and the second detector housing 2. At this time, the steel wire rope can be placed exactly in the middle of the first intermediate shield 3 and the second intermediate shield 4, and the detector closely adheres to the steel wire rope.;

[0033] Please refer to Figure 1 and Figure 2 As shown, the magnetic pole arrangement directions of the first permanent magnet 13 and the second permanent magnet 14 are the same, and the first permanent magnet 13, the second permanent magnet 14 and the magnetic sensors 29 are located on the same horizontal plane. In the early stage, the electrons of the steel wire rope are rearranged by the magnets, so that the directions of the electrons are the same. The magnetized part of the steel wire rope enters the first intermediate shield 3 and the second intermediate shield 4. The first permanent magnet 13 and the second permanent magnet 14 sense the electron distribution of the magnetic field, so that the magnetic sensors 29 can know the internal structure of the steel wire rope at the abnormal electron position of the steel wire rope.

[0034] When the wire rope needs to pass through the detector, the detector is opened, the buckle 9 of the first detector housing 1 and the connecting plate 10 of the second detector housing 2 are opened, so that the first detector housing 1 and the second detector housing 2 are separated, and at this time, the first detector housing 1 and the second detector housing 2 rotate around the connecting pin 6, and the first detector housing 1 and the second detector housing 2 are opened, so that the wire rope is placed between the first intermediate shield 3 and the second intermediate shield 4, and the DC or permanent magnet instrument provides a constant magnetic flux. After the magnetized wire rope, the wire rope is affected by the previous magnetic field, so that the electrons inside the wire rope are magnetized, so that the directions of the electrons are arranged in the same way, and the electronic arrangement of the wire rope can be sensed by the magnetic sensor 29, wherein the magnetic sensor 29 can be detected by a Hall effect sensor, an induction coil or other appropriate devices, and the sensor outputs an electrical signal. The wire rope passes through the first intermediate shield 3 and the second intermediate shield 4, and the electronic arrangement of the wire rope can be sensed, so that the electronic condition of the wire rope is simulated by computer software, and the computer software can be used to know whether there are defects inside the wire rope.

[0035] See also Figure 1 , Figure 3 and Figure 4 As shown, the axis adjustment structure includes a first support plate 21 arranged at the two first pole shoes 15, the first support plate 21 is fixed to the first pole shoe 15, the first support plate 21 and the first pole shoe 15 are fixed by bolts, a first rotating shaft 18 is arranged between the two sides of the first support plate 21, a fixing frame 17 is sleeved on the outside of the first rotating shaft 18, the fixing frame 17 can rotate around the first rotating shaft 18, a fixing wheel 7 is arranged at the end of the fixing frame 17, the fixing wheel 7 is in contact with the wire rope, so that when the first detector housing 1 and the second detector housing 2 move along the wire rope, the fixing wheel 7 always places the wire rope inside the first intermediate shield 3 and the second intermediate shield 4, reducing the contact between the first intermediate shield 3 and the second intermediate shield 4 and the wire rope, and the bottom end of the fixing frame 17 is opened There is a threaded hole 20, and the internal thread of the threaded hole 20 is connected with a fixing bolt 19. The fixing wheel 7 is in contact with the clamping structure. When the position of the fixing frame 17 needs to be adjusted, the position of the fixing wheel 7 can be adjusted according to the diameter of the wire rope. Specifically, the fixing bolt 19 rotates in the threaded hole 20, and the fixing frame 17 rotates around the first rotating shaft 18, so that the fixing wheel 7 approaches the middle, and a thinner wire rope can be placed between the first intermediate guard 3 and the second intermediate guard 4. Similarly, the fixing bolt 19 is unscrewed from the threaded hole 20, and the fixing frame 17 rotates around the first rotating shaft 18, so that the fixing wheel 7 is away from the middle position between the first intermediate guard 3 and the second intermediate guard 4, and a wire rope with a larger diameter can be placed between the first intermediate guard 3 and the second intermediate guard 4.

[0036] See also Figure 3 and Figure 4 As shown, the end of the fixing bolt 19 is always in contact with the first support plate 21, the rotation axis of the fixing frame 17 coincides with the axis of the first rotation axis 18, the length of the fixing bolt 19 screwed into the threaded hole 20 will affect the position of the fixing frame 17, and the deflection angle of the fixing frame 17 around the first rotation axis 18 is positively correlated with the depth of the fixing bolt 19 screwed into the threaded hole 20. The longer the fixing bolt 19 is screwed into the threaded hole 20, the closer the fixing frame 17 is to the center. On the contrary, the shorter the fixing bolt 19 is screwed into the threaded hole 20, the closer the fixing frame 17 is to the side.

[0037] In order to ensure that the position of the wire rope is located in the middle of the first intermediate shield 3 and the second intermediate shield 4, the position of the fixed wheel 7 can be adjusted by the axis adjustment structure. Specifically, the fixing bolt 19 is rotated to change the position of the fixing bolt 19 and the threaded hole 20. At this time, the end of the fixing bolt 19 is against the first support plate 21, so that the fixing frame 17 rotates around the first rotating shaft 18, so that the position of the fixed wheel 7 is close to the middle or away from the middle, thereby changing the position of the fixed wheel 7 according to the diameter of the wire rope, so that the wire rope is determined by the cooperation of the fixed wheel 7 and the movable wheel 8. The wire rope is located in the middle of the first intermediate shield 3 and the second intermediate shield 4, and the movable wheel 8 is attached to the wire rope, which can avoid the wire rope from contacting the inner wall of the first intermediate shield 3 and the second intermediate shield 4. The position in the middle of the first intermediate shield 3 and the second intermediate shield 4 can ensure that the wire rope is affected by the magnetic fields of the first permanent magnet 13 and the second permanent magnet 14 in the same way.

[0038] See also Figure 1 and Figure 5 As shown, the clamping structure includes a second support plate 25 arranged at the two second pole shoes 16, the second support plate 25 is fixed to the second pole shoe 16, the second pole shoe 16 and the second support plate 25 are fixed by bolts, and the second support plate 25 corresponds to the first support plate 21, a second rotating shaft 23 is arranged between the two sides of the second support plate 25, a swing frame 22 is sleeved on the outside of the second rotating shaft 23, the swing frame 22 rotates around the second rotating shaft 23, a torsion spring 24 is arranged on the outside of the second rotating shaft 23, and the swing frame 22 is moved toward the middle by the action of the torsion spring 24, and a movable wheel 8 is arranged at the end of the swing frame 22, and the movable wheel 8 is in contact with the axis adjustment structure, so that the movable wheel 8 approaches and fits the fixed wheel 7.

[0039] See also Figure 5As shown, the cylindrical surface of the fixed wheel 7 is provided with a first annular groove 26, and the cylindrical surface of the movable wheel 8 is provided with a second annular groove 27. The center of the largest circle surrounded by the first annular groove 26 and the second annular groove 27 is aligned with the center of the wire rope. The area surrounded by the straight line where the two fixed frames 17 are located and the straight line where the two swing frames 22 are located is a diamond shape. The movable wheel 8 is fitted on the fixed wheel 7, and the wire rope between the fixed wheel 7 and the movable wheel 8 can be bound. Similarly, under the action of the torsion spring 24, the fixed wheel 7 and the movable wheel 8 are tightly fitted to prevent the wire rope from detaching from between the fixed wheel 7 and the movable wheel 8.

[0040] See also Figure 1 , Figure 7 and Figure 8 As shown, hinge holes 5 are provided on the same side edges of the first detector housing 1 and the second detector housing 2, a connecting pin 6 is inserted between the hinge holes 5 of the first detector housing 1 and the hinge holes 5 of the second detector housing 2, and the first detector housing 1 and the second detector housing 2 are rotatably connected. When the first detector housing 1 and the second detector housing 2 are closed, the hinge holes 5 rotate around the connecting pin 6, thereby realizing the opening and closing of the first detector housing 1 and the second detector housing 2, and buckles 9 and connecting plates 10 are provided on the other side edges of the first detector housing 1 and the second detector housing 2, the buckles 9 and the connecting plates 10 are buckled with each other, and when the first detector housing 1 and the second detector housing 2 are closed, the buckles 9 and the connecting plates 10 can be buckled and locked with each other, and the buckles 9 and the connecting plates 10 are opened to each other before the first detector housing 1 and the second detector housing 2 are opened.

[0041] See also Figure 6-Figure 8 As shown, the end of the limiting copper bar 11 is in an arc shape, and the limiting copper bar 11 is clamped between the first intermediate protective cover 3 and the second intermediate protective cover 4. When the first detector housing 1 and the second detector housing 2 are closed, the opening of the limiting copper bar 11 contacts the second intermediate protective cover 4, so that the limiting copper bar 11 can be inserted into the second intermediate protective cover 4, thereby making the first intermediate protective cover 3 and the second intermediate protective cover 4 more securely closed.

[0042] When the present invention is in use, in the nondestructive electromagnetic detection method based on the magnetic flux leakage principle in the detection of the wire rope, the first detector housing 1 and the second detector housing 2 are opened to allow the wire rope to be placed between the first intermediate shield 3 and the second intermediate shield 4, and then the first detector housing 1 and the second detector housing 2 are fastened and locked by the buckle 9 and the connecting plate 10, so that the wire rope can be placed inside the detector. At this time, the axis adjustment structure adjusts the position of the fixed wheel 7 according to the diameter of the wire rope, specifically, the fixing bolt 19 is tightened, so that the fixing frame 17 can rotate around the first rotating shaft 18, so that the fixing wheel 7 can move closer to the middle, and after adjusting the position of the fixing wheel 7, the position of the fixing bolt 19 is stopped, so that the fixing wheel 7 can adjust the wire rope position according to the diameter of the wire rope. The position inside the protective cover 3 and the second intermediate protective cover 4 is such that the axis of the wire rope when straightened is aligned with the axis of the first intermediate protective cover 3 and the second intermediate protective cover 4, and the movable wheel 8 fits with the fixed wheel 7 so that the wire rope can pass through the position of the axis of the intermediate protective cover, so that the distance between the wire rope and the two limiting copper bars 11 and the second permanent magnet 14 is the same. Since the staff needs to move the detector along the wire rope, it is easy for the measuring device to fall off the wire rope. At this time, the clamping structure can be rotated toward the middle under the action of the torsion spring 24, so that the movable wheel 8 of the swing frame 22 approaches the fixed wheel 7. At this time, the fixed wheel 7 and the movable wheel 8 fit tightly, so that the wire rope is located between the fixed wheel 7 and the movable wheel 8, and the wire rope is not easy to fall off from between the fixed wheel 7 and the movable wheel 8.
