Description

Technical Field

[0001] This utility model relates to the field of wire rope flaw detection technology, specifically to a portable wire rope flaw detection device for mining. Background Technology

[0002] With the expansion of mining scale and the increase in mining depth, wire ropes are subjected to complex working conditions of high load, dust, moisture and impact vibration for a long time, which makes them prone to defects such as broken wires, corrosion and wear. If these defects are not detected in time, they may lead to wire rope breakage, equipment shutdown or even safety accidents. Therefore, regular and accurate flaw detection of wire ropes has become an important part of mine safety production management.

[0003] When using existing portable wire rope flaw detection devices for mining, most of them are directly nested on the outer wall of the wire rope, resulting in poor stability during application. They often cannot properly clamp the wire rope, making it very inconvenient for operators to handle during the inspection process. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a portable wire rope flaw detection device for mining, which has the advantages of providing stable clamping for the wire rope, being easy for operators to hold, and simultaneously cleaning impurities on the surface of the wire rope. This solves the problems of poor stability, inadequate clamping effect, and inconvenience for operators caused by existing wire rope flaw detection devices being directly nested on the outer wall of the wire rope.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a portable steel wire rope flaw detection device for mining, comprising an upper shell and a lower shell, the upper shell and the lower shell being connected together by hinges; two first supports are symmetrically fixedly installed at both ends of the lower shell near the bottom, and a downward pressure wheel is fixedly installed between the two first supports; a connecting rod is fixedly installed at the other end of each of the two first supports, and a steel wire brush plate is fixedly installed between the two connecting rods; second supports are fixedly installed at both ends of the upper shell; a rectangular hole is provided on the side of the upper shell near the top; clamping components for clamping the steel wire rope are provided at both ends of the upper shell; an adjustment component is provided at the top of the upper shell, the adjustment component working in conjunction with the clamping component; a locking component is provided inside the rectangular hole, the rectangular hole working in conjunction with the locking component; the clamping component consists of an L-shaped connecting rod and a second connecting rod; and the adjustment component consists of a rectangular guide tube and a ratchet.

An upper pressure wheel is rotatably installed inside the movable groove, and the upper pressure wheel is used in conjunction with a lower pressure wheel.

[0007] As a preferred technical solution of this utility model, the clamping assembly further includes two connecting rods II. The two connecting rods II are symmetrically fixedly installed at one end of the L-shaped connecting rod near the upper pressure wheel. A wire brush plate II is fixedly installed between the two connecting rods II. The wire brush plate II is used in conjunction with the wire brush plate I.

[0008] As a preferred technical solution of this utility model, the adjustment component includes a ratchet, which is rotatably mounted on the top of the upper housing. A connecting post is fixedly installed at the center of the top of the ratchet, and an adjustment circular plate is fixedly installed at the top of the connecting post. Two arc-shaped guide grooves are equidistantly formed on the top circumference of the adjustment circular plate.

[0009] As a preferred embodiment of this utility model, the adjustment assembly further includes two rectangular guide tubes, which are symmetrically and fixedly installed on the top of the upper housing.

[0011] As a preferred embodiment of the present invention, the locking assembly includes two U-shaped locking rods. One end of each of the two U-shaped locking rods is movably installed inside a rectangular hole. A spring is fixedly installed between the two ends of the two U-shaped locking rods located inside the rectangular hole. The other ends of the two U-shaped locking rods are distributed in a mirror image on the outside of the ratchet with the axis of the ratchet as the center of symmetry.

[0012] As a preferred embodiment of this utility model, the ends of the two U-shaped locking rods near the outer side of the ratchet are both trapezoidal structures, which are adapted to the trapezoidal teeth on the outer side of the ratchet. The inclination direction of the trapezoidal teeth on the outer side of the ratchet is opposite to the inclination direction of the trapezoidal structures at the ends of the two U-shaped locking rods near the ratchet.

[0013] The beneficial effects of this utility model are as follows: This invention uses an upper pressure wheel and a lower pressure wheel to form a clamping structure, which can stably clamp the wire rope.

[0017] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0018] Figures 1-8This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 - Appendix Figure 8 The present invention will be further described below.

[0019] A portable wire rope flaw detection device for mining includes an upper housing 1 and a lower housing 2, which are connected together by hinges. Two first supports 3 are symmetrically fixed at both ends of the lower housing 2 near the bottom, and a pressure wheel 4 is fixedly installed between the two first supports 3. A connecting rod 5 is fixedly installed at the other end of each of the two first supports 3, and a wire brush plate 6 is fixedly installed between the two connecting rods 5. Second supports 7 are fixedly installed at both ends of the upper housing 1. A rectangular hole 8 is provided on one side of the upper housing 1 near the top. Clamping components for clamping the wire rope are provided at both ends of the upper housing 1. An adjustment component is provided at the top of the upper housing 1, which works in conjunction with the clamping components. A locking component is provided inside the rectangular hole 8, which works in conjunction with the locking component. The clamping component consists of an L-shaped connecting rod 9 and a connecting rod 13. The adjustment component consists of a rectangular guide tube 15 and a ratchet 18.

[0020] In this embodiment, the upper housing 1 serves as the upper support frame of the device, providing an installation base for the second bracket 7, rectangular hole 8, clamping assembly, and adjustment assembly. Simultaneously, the detection plate inside the upper housing 1 is one of the core components for flaw detection, working in conjunction with the detection plate inside the lower housing 2 to detect defects in the wire rope. The lower housing 2, as the lower support structure of the device, provides fixed points for the first brackets 3 at both ends. The detection plate inside the lower housing 2 corresponds to the detection plate inside the upper housing 1, jointly completing the flaw detection work. It is connected to the upper housing 1 via hinges, allowing for flexible opening and closing, facilitating the placement of the wire rope into the device. Two first brackets 3 are symmetrically fixed at both ends of the lower housing 2 near the bottom. Two first brackets 3 are fixed at one end, and at the other end, in addition to the pressure wheel 4, a connecting rod 5 is also fixed. The connecting rod 5 provides support for the lower pressure wheel 4, which is installed between the two first supports 3 at both ends and cooperates with the upper pressure wheel 12 in the clamping assembly to support and clamp the wire rope from below, guiding the wire rope smoothly through the detection area between the upper housing 1 and the lower housing 2. The connecting rod 5 is fixed only to the other end of the two first supports 3 at one end of the lower housing 2 and is connected to the first support 3 to provide fixed support for the wire brush plate 6, ensuring that the wire brush plate 6 can be stably positioned close to the lower pressure wheel 4 and cooperate with the wire brush plate 14 in the clamping assembly to clean the wire rope. The second support 7 is fixed at both ends of the upper housing 1 and provides a rotation mounting fulcrum for the L-shaped connecting rod 9 in the clamping assembly, ensuring that the L-shaped connecting rod 9 can rotate flexibly around the second support 7, thereby driving the L-shaped connecting rod 9 in the clamping assembly to rotate flexibly around the second support 7. The upper pressure roller 12 and the second wire brush plate 14 are adjusted to achieve precise clamping and cleaning of the wire rope. The rectangular hole 8 is opened on the side of the upper housing 1 near the top, providing installation and movement space for the locking assembly. The clamping assembly is used to stably clamp and clean the wire rope. The L-shaped connecting rod 9 rotates around the second bracket 7, driving the upper pressure roller 12 and the lower pressure roller 4 to clamp the wire rope. At the same time, the connecting rod 13 drives the second wire brush plate 14 to cooperate with the first wire brush plate 6 at one end of the lower housing 2 to clean impurities on the surface of the wire rope. The adjustment assembly adjusts the position of the rectangular rod 16 by rotating the ratchet 18, thereby pushing or pulling the L-shaped connecting rod 9 to adjust the clamping force and position of the clamping assembly to meet the clamping requirements of the wire rope and ensure the upper pressure roller in the clamping assembly is in place. 12 remains in constant contact with the wire rope, creating stable testing conditions for the detection plate. Two U-shaped locking rods 23 in the locking assembly are movably installed inside the rectangular hole 8, working in conjunction with it to fix the state of the adjustment assembly after adjustment, preventing loosening of the clamping assembly. The flaw detection principle is electromagnetic induction. The detection plate inside the upper housing 1 and lower housing 2 is an electromagnetic induction component, generating a magnetic field that passes through the wire rope. When the wire rope has defects such as broken wires, corrosion, or wear, the magnetic resistance at the defect increases. The magnetic field that originally propagated along the inside of the wire rope will overflow from the defect, forming a leakage magnetic field. After the detection plate captures the leakage magnetic field signal, it converts it into an electrical signal, which is transmitted to the external display screen. Different colors are displayed on the screen to mark the defect location.This allows us to determine the nature and specific location of defects in the wire rope.

[0021] Specifically, the clamping assembly includes an L-shaped connecting rod 9, which is rotatably installed inside the second bracket 7. One end of the L-shaped connecting rod 9 near the upper housing 1 is provided with a movable groove 10, and the other end of the L-shaped connecting rod 9 is provided with a movable groove 11. An upper pressure roller 12 is rotatably installed inside the movable groove 11, and the upper pressure roller 12 works in conjunction with the lower pressure roller 4.

[0022] In this embodiment, an L-shaped connecting rod 9 is rotatably installed inside the second bracket 7, allowing it to rotate flexibly around the second bracket 7. One end is connected to the rectangular rod 16 of the adjustment component via a movable slot 10, receiving the action transmitted from the adjustment component. The other end is installed with an upper pressure roller 12 via a movable slot 2 11, driving the upper pressure roller 12 to adjust its height, thereby clamping or releasing the wire rope. The second bracket 7 is fixed at both ends of the upper housing 1, providing a fulcrum for the rotation of the L-shaped connecting rod 9, restricting the movement trajectory of the L-shaped connecting rod 9, ensuring that the L-shaped connecting rod 9 can only rotate around itself, and preventing the L-shaped connecting rod 9 from deviating, which would cause the upper pressure roller 12 to fail to align precisely with the lower pressure roller 4, thus ensuring the stability of the clamping component's operation.

[0023] Specifically, the clamping assembly also includes two connecting rods 13. The two connecting rods 13 are symmetrically fixedly installed at one end of the L-shaped connecting rod 9 near the upper pressure roller 12. A wire brush plate 14 is fixedly installed between the two connecting rods 13. The wire brush plate 14 is used in conjunction with the wire brush plate 6.

[0024] In this embodiment, two connecting rods 13 are symmetrically fixedly installed on the L-shaped connecting rod 9 corresponding to the second bracket 7 at the end of the upper housing 1 near the connecting rod 5. The L-shaped connecting rod 9 corresponding to the second bracket 7 at the other end does not have this structure, and one end of it is fixed to the L-shaped connecting rod 9. A wire brush plate 14 is fixedly installed between the two connecting rods 13, providing stable installation support for the wire brush plate 14 and ensuring that the wire brush plate 14 can accurately correspond to the wire brush plate 6 of the lower housing 2, forming an upper and lower cleaning structure. The wire brush plate 14 and the wire brush plate 6 can cooperate with each other to perform simple cleaning of impurities attached to the surface of the wire rope, avoiding excessive impurities from affecting the detection effect.

[0025] Specifically, the adjustment assembly includes a ratchet 18, which is rotatably mounted on the top of the upper housing 1. A connecting post 19 is fixedly mounted at the center of the top of the ratchet 18, and an adjustment circular plate 20 is fixedly mounted on the top of the connecting post 19. Two arc-shaped guide grooves 21 are equidistantly formed on the top circumference of the adjustment circular plate 20.

[0026] In this embodiment, a ratchet 18 is rotatably mounted on the top of the upper housing 1, allowing it to rotate around its own axis. A fixed connecting post 19 at the top center drives the connecting post 19 and the adjusting circular plate 20 to rotate synchronously. It can also cooperate with the U-shaped locking rod 23 in the locking assembly to prevent the clamping assembly from failing due to the ratchet 18's positional misalignment. The adjusting circular plate 20 is fixed to the ratchet 18 via the connecting post 19 and rotates synchronously with the ratchet 18. Two arc-shaped guide grooves 21 are equidistantly provided on the top circumference to provide a movement trajectory for the subsequent adjusting block 17, converting its own circumferential rotation into the radial movement of the adjusting block 17, thereby driving the rectangular rod 16 to move and achieve adjustment of the clamping assembly. Two arc-shaped guide grooves 21 are equidistantly provided on the top circumference of the adjusting circular plate 20. Their arc-shaped structure guides the adjusting block 17 to move along the groove, limiting the direction and range of movement of the adjusting block 17 and ensuring that the adjusting block 17 drives the rectangular rod 16 to move smoothly within the rectangular guide tube 15.

[0027] Specifically, the adjustment assembly also includes two rectangular guide tubes 15, which are symmetrically fixedly installed on the top of the upper housing 1. A rectangular rod 16 is movably sleeved inside the rectangular guide tube 15. One end of the rectangular rod 16 is movably installed between the adjustment disc 20 and the ratchet 18, and the other end of the rectangular rod 16 is rotatably installed inside the movable groove 10.

[0028] In this embodiment, two rectangular guide tubes 15 are symmetrically fixed on the top of the upper housing 1 to provide movement guidance and support for the rectangular rod 16, restricting the rectangular rod 16 to only extend and retract along the axial direction of the rectangular guide tube 15, thus preventing the rectangular rod 16 from deviating or swaying. One end of the rectangular rod 16 is movably installed between the adjusting circular plate 20 and the ratchet 18, and can move along the rectangular guide tube 15 as the adjusting circular plate 20 rotates. The other end is rotatably installed in the movable slot 10, which can convert its own linear movement into the rotation of the L-shaped connecting rod 9, thereby driving the upper pressure roller 12 to adjust its height.

[0029] Specifically, the adjustment assembly also includes two adjustment blocks 17. The adjustment blocks 17 are fixedly installed on the top of the rectangular rod 16 near the end of the adjustment circular plate 20, and the adjustment blocks 17 are movably sleeved inside the arc-shaped guide groove 21.

[0030] In this embodiment, by setting the adjustment block 17 to be fixed on the top of the rectangular rod 16 near the adjustment circular plate 20, and movably sleeved in the arc-shaped guide groove 21, it can move along the arc-shaped guide groove 21 as the adjustment circular plate 20 rotates, and at the same time drive the rectangular rod 16 to extend and retract in the rectangular guide tube 15.

[0031] Specifically, the locking assembly includes two U-shaped locking rods 23. One end of each U-shaped locking rod 23 is movably installed inside the rectangular hole 8. A spring 22 is fixedly installed between the two ends of the U-shaped locking rods 23 inside the rectangular hole 8. The other ends of the two U-shaped locking rods 23 are distributed in a mirror image on the outside of the ratchet 18 with the axis of the ratchet 18 as the center of symmetry.

[0032] In this embodiment, two U-shaped locking rods 23 are provided. One end is movably installed inside the rectangular hole 8, and the other end is distributed symmetrically around the axis of the ratchet 18 on the outside of the ratchet 18. Under the elastic force of the spring 22, the outer end can fit against the outer wall of the ratchet 18. Utilizing its own structure to cooperate with the trapezoidal teeth of the ratchet 18, it prevents the ratchet 18 from rotating in the opposite direction. At the same time, the rectangular hole 8 can limit its range of motion, ensuring accurate locking position. The spring 22 is fixed between the two ends of the two U-shaped locking rods 23 located inside the rectangular hole 8, and always applies an inward traction force to the two U-shaped locking rods 23, pulling the outer end of the U-shaped locking rod 23 to fit tightly against the outside of the ratchet 18, ensuring that the U-shaped locking rod 23 can be promptly engaged in the trapezoidal teeth of the ratchet 18, avoiding locking failure due to loosening of the U-shaped locking rod 23, and maintaining a stable locking state.

[0033] Specifically, the ends of the two U-shaped locking rods 23 near the outer side of the ratchet 18 are both trapezoidal structures, which are adapted to the trapezoidal teeth on the outer side of the ratchet 18. The inclination direction of the trapezoidal teeth on the outer side of the ratchet 18 is opposite to the inclination direction of the trapezoidal structures at the ends of the two U-shaped locking rods 23 near the ratchet 18.

[0034] In this embodiment, two U-shaped locking rods 23 are set with trapezoidal structures at their ends near the outer side of the ratchet 18. These trapezoidal structures are adapted to the trapezoidal teeth on the outer side of the ratchet 18, and the two are tilted in opposite directions. Under the inward traction force of the spring 22, the trapezoidal structure can be precisely engaged in the gap between the trapezoidal teeth of the ratchet 18. The reverse tilting structure forms a one-way limit, preventing the ratchet 18 from rotating in the opposite direction, ensuring the locking effect of the locking component on the adjustment component, and preventing the clamping state from loosening after adjustment.

[0035] In summary: When using this utility model, firstly, manually open the upper housing 1 and lower housing 2 connected by hinges. Place the stationary steel wire rope to be tested on the pressure roller 4 between the two first supports 3 at both ends of the lower housing 2, ensuring the steel wire rope's position corresponds to the detection area of ​​the detection plate inside the upper housing 1 and lower housing 2. Next, manually close the upper housing 1 and lower housing 2, and secure them together using the connecting buckles on the outer sides of the upper housing 1 and lower housing 2 to prevent separation during subsequent operations. Then, manually rotate the wheel at the top of the adjusting disc 20. The wheel drives the adjusting disc 20, connecting column 19, and ratchet 18 in the adjusting assembly to rotate together. The two arc-shaped guide grooves 21 on the top circumference of the adjusting disc 20 rotate with the adjusting disc 20. The adjusting block 17, which is mounted inside the arc-shaped guide groove 21 and fixed to the top of the rectangular rod 16 near the adjusting circular plate 20, moves along the arc-shaped guide groove 21 and drives the rectangular rod 16 to extend axially within the rectangular guide tube 15. The end of the rectangular rod 16 away from the adjusting circular plate 20 is rotatably installed in the movable groove 10 of the L-shaped connecting rod 9 in the clamping assembly. When the rectangular rod 16 extends, it pushes the L-shaped connecting rod 9 to rotate around the second bracket 7 fixed at both ends of the upper housing 1. The upper pressure wheel 12, which is rotatably installed in the movable groove 11 at the other end of the L-shaped connecting rod 9, adjusts its position as the L-shaped connecting rod 9 rotates until the upper pressure wheel 12 cooperates with the lower pressure wheel 4 of the lower housing 2 to clamp the wire rope. At the same time, two connecting rods 13, which are symmetrically fixed on the L-shaped connecting rod 9 near the connecting rod 5 of the upper housing 1, are also present. This causes the steel wire brush plate 24, which is fixed between them, to move, so that the steel wire brush plate 24 and the steel wire brush plate 6 cooperate to wrap the steel wire rope. During the adjustment of the adjustment component, the two U-shaped locking rods 23, which are movably installed inside the rectangular hole 8 in the locking component, are subjected to the inward traction force applied by the spring 22 fixed between their ends inside the rectangular hole 8. The other ends are mirror-distributed on the outside of the ratchet 18 with the axis of the ratchet 18 as the center of symmetry. The trapezoidal structure of the U-shaped locking rod 23 near the ratchet 18 is adapted to the trapezoidal teeth on the outside of the ratchet 18 with the opposite inclination direction. As the ratchet 18 rotates in the forward direction, the trapezoidal structure of the U-shaped locking rod 23 slides smoothly along the trapezoidal teeth of the ratchet 18. When the adjustment is completed and the ratchet 18 stops rotating, the traction force of the spring 22 causes the U-shaped locking rod 23 to... The trapezoidal structure engages with the trapezoidal tooth gap of the ratchet 18, preventing the ratchet 18 from rotating in the opposite direction, thereby fixing the state of the adjustment component and ensuring the stable clamping of the wire rope by the clamping component. Then, the device is started, and the operator lifts the two handles on the top of the upper housing 1, moving the upper housing 1 and the lower housing 2 outside the stationary wire rope. The detection plates inside the upper housing 1 and the lower housing 2 move with the housing and slide along the outer wall of the wire rope. During this process, the wire brush plate 2 14 and the wire brush plate 1 6 will simultaneously clean the impurities on the surface of the wire rope. After cleaning, the wire rope passes through the detection plate. As an electromagnetic induction component, the detection plate will generate a magnetic field and pass through the wire rope. If the wire rope has defects such as broken wires, corrosion, or wear, the magnetic resistance at the defect will increase, and the magnetic field will overflow from the defect to form a leakage magnetic field.After capturing the leakage magnetic field signal, the detection board converts it into an electrical signal, which is then transmitted to an external display screen. The display screen marks the defect location with different colors, enabling comprehensive flaw detection of the wire rope.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
