Description

Technical Field

[0001] The present invention relates to the technical field of detection, and specifically provides a non-destructive testing device and method for offshore steel wire ropes. Background Technique

[0002] A steel wire rope is a helical steel wire bundle formed by twisting steel wires that meet the requirements of mechanical properties and geometric dimensions together according to certain rules. A steel wire rope consists of steel wires, a rope core, and lubricating grease. First, multiple layers of steel wires are twisted into strands, and then, with the rope core as the center, a certain number of strands are twisted into a helical rope. In material handling machinery, it is used for lifting, traction, tensioning, and load bearing. Steel wire ropes have high strength, low self-weight, stable operation, and are not likely to break suddenly as a whole, and are reliable in work. In 1834, a European named Orubt invented the world's first steel wire rope (smooth steel wire rope). The Tianjin No. 1 Steel Wire Rope Factory established in 1939 was the first metal products enterprise in China.

[0003] For example, the invention patent "A Pulse Eddy Current Non-Destructive Testing Device and Method for Steel Wire Ropes" of Chinese Patent No. 201610239801.2 discloses a pulse eddy current non-destructive testing device for steel wire ropes, including the following steps: signal detection stage, data acquisition stage, and data processing stage; the signal detection device includes: a pulse eddy current probe and a Hall sensor; when a pulsed square wave excitation signal passes through the coil of the pulse eddy current probe, eddy currents flowing in a swirling shape are formed inside the steel wire rope, and the eddy currents of the steel wire rope form the magnetic field of the steel wire rope; the Hall sensor receives the changing magnetic field of the steel wire rope, and the Hall element converts the changing magnetic field signal into a voltage signal for output; the data acquisition device transmits the voltage signal to

[0004] the data processing device. The pulse eddy current non-destructive testing device for steel wire ropes of the present invention combines the pulse eddy current detection principle and method to realize a non-destructive testing device for steel wire ropes with high power and small volume; the supporting guide wheels and detection probes in the testing device can be adaptively adjusted according to the diameter of the steel wire rope to adapt to the detection of different types of steel wire ropes.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 to 6 , the present invention provides a technical solution: an offshore steel wire rope non-destructive testing device and its testing method, including a fixed bottom plate 1. A eddy current testing device 7 for detecting the steel wire rope is fixedly connected to the top of the fixed bottom plate 1. A marking block 8 is arranged on the top of the fixed bottom plate 1. A driving mechanism for driving the marking block 8 to mark the steel wire rope is fixedly connected to the fixed bottom plate 1. The driving mechanism is electrically connected to the eddy current testing device 7;

[0036] A transmission mechanism for stably transmitting the steel wire rope is fixedly connected to the top of the fixed bottom plate 1. When a person needs to detect whether the steel wire rope is damaged, first, the steel wire rope is stably transmitted through the transmission mechanism. The transmission mechanism can be set to two so that the steel wire rope between the two transmission mechanisms is in a straight state, and the eddy current testing device 7 is between the two transmission mechanisms, so that the eddy current testing device 7 can detect the steel wire rope in a straight state, thereby obtaining more accurate data. When the eddy current testing device 7 detects that the steel wire rope is severely damaged, the driving mechanism causes the marking block 8 to mark the steel wire rope, so that the person can clearly know that there is a problem with the steel wire rope. And it can be set to give an alarm and make a sound.

[0037] Specifically, the driving mechanism includes a second auxiliary plate 12 fixedly connected to the top of the fixed bottom plate 1. A first rotating column 9 is rotatably connected to the second auxiliary plate 12. One end of the first rotating column 9 is fixedly connected to the power output end of the second motor 6. A third disc 10 is fixedly connected to the end of the first rotating column 9 away from the second motor 6. A first connecting rod 21 is fixedly connected to the outer wall of the third disc 10. One side of the first connecting rod 21 away from the third disc 10 is hinged to a first hinged rod 11. One side of the first hinged rod 11 away from the first connecting rod 21 is hinged to one side of the marking block 8. The second motor 6 is electrically connected to the eddy current testing device 7. When a problematic steel wire rope is detected, the second motor 6 is started, so that the first rotating column 9 and the third disc 10 rotate in a circle. The third disc 10 rotating in a circle causes the marking block 8 to move horizontally through the first connecting rod 21 and the first hinged rod 11. Here, the marking block 8 is slidably connected to the eddy current testing device 7 in a limited way. The marking block 8 touches the steel wire rope, thereby making a mark.

[0038] Specifically, the transmission mechanism includes a first auxiliary plate 3 fixedly connected to the top of the fixed base plate 1. A first disc 4 and a second disc 5 are rotatably connected to the first auxiliary plate 3. One end of the second disc 5 is fixedly connected to the power output end of the third motor 35. Starting the third motor 35 causes the second disc 5 to rotate, and then through the cooperation of the first disc 4 and the second disc 5, the steel wire rope is smoothly transmitted therein.

[0039] Specifically, an industrial alcohol tank 13 and a third auxiliary plate 20 are fixedly connected to the top of the fixed base plate 1. A second rotating column 19 that can rotate circumferentially is rotatably connected between the industrial alcohol tank 13 and the third auxiliary plate 20. The second rotating column 19 is fixedly connected to the eccentric position of the fifth disc 27. A sliding frame 28 is rotatably connected to the outer wall of the fifth disc 27. The bottom of the sliding frame 28 is fixedly connected to a connecting frame 29. A fifth auxiliary plate 30 is fixedly connected to the top of the fixed base plate 1. A sliding column 32 is fixedly connected to one side of the fifth auxiliary plate 30. The sliding column 32 is slidably connected to the inner wall of the connecting frame 29. A wire frame 31 for guiding the steel wire rope is fixedly connected to one side of the connecting frame 29 near the bottom. The steel wire rope passes through the wire frame 31 and is guided by the wire frame 31. Then, the rotating second rotating column 19 drives the fifth disc 27 to rotate eccentrically, and then cooperates with the sliding frame 28, the connecting frame 29, and the sliding column 32 to make the connecting frame 29 swing continuously, so that the steel wire rope in the wire frame 31 is continuously brushed. This makes the detection of the steel wire rope more accurate and facilitates clean winding. Multiple such devices can be provided.

[0040] Specifically, a spline bushing 16 is rotatably connected to the third auxiliary plate 20. One end of the spline bushing 16 is fixedly connected to the power output end of the first motor 2. A spline shaft 17 for sleeving the winding rod is slidably connected inside the spline bushing 16;

[0041] The outer wall of the spline shaft sleeve 16 is fixedly connected with a gear 18. The top of the fixed base plate 1 is fixedly connected with a fourth auxiliary plate 24. A third rotating column 25 is rotatably connected to the fourth auxiliary plate 24. The side of the third rotating column 25 away from the fourth auxiliary plate 24 is fixedly connected with a fourth disc 23. Tooth teeth 26 are arranged at the peripheral edge of one side of the fourth disc 23. The tooth teeth 26 are meshed with the gear 18. The outer wall of the fourth disc 23 is fixedly connected with a second connecting rod 33. The side of the second connecting rod 33 away from the fourth disc 23 is hinged with a second hinge rod 34. A chute 14 is formed in the top of the fixed base plate 1. A slider 15 is slidably connected to the top of the chute 14. The side of the second hinge rod 34 away from the second connecting rod 33 is hinged with the slider 15. The spline shaft 17 is rotatably connected to the slider 15 through a bearing. When the power supply of the first motor 2 is started, the first motor 2 drives the spline shaft sleeve 16 to rotate. The rotating spline shaft sleeve 16 drives the spline shaft 17 to rotate. The spline shaft 17 drives the material receiving roller to rotate, so as to carry out material receiving. And the rotating spline shaft sleeve 16 drives the gear 18 to rotate. The gear 18 makes the fourth disc 23 rotate through the cooperation with the tooth teeth 26. The rotating fourth disc 23 cooperates with the second connecting rod 33 and the second hinge rod 34 to make the slider 15 move horizontally back and forth. Thus, multi-dimensional winding is carried out, and steel wires of multiple widths are wound on the material receiving roller. Thus, more steel wires can be wound on the material receiving roller, and it is more convenient for transportation.

[0042] A detection method for a non-destructive detection device for offshore steel wire ropes includes the following steps:

[0043] The first step: Set two groups of first discs 4 and second discs 5. Place the steel wire rope between the first discs 4 and the second discs 5, so that the steel wire rope remains in a straightened state between the two groups of first discs 4 and second discs 5;

[0044] The second step: Set the eddy current detection device 7 between the two groups of first discs 4 and second discs 5 to detect the state of the steel wire rope;

[0045] The third step: Make the steel wire rope located in the wire frame 31. Then start the power supply of the first motor 2. The first motor 2 makes the spline shaft sleeve 16 rotate circumferentially. The spline shaft sleeve 16 drives the second rotating column 19 to rotate through the belt 22. The second rotating column 19 makes the connecting frame 29 swing back and forth in the industrial alcohol tank 13 through the cooperation of the fifth disc 27, the sliding frame 28, the connecting frame 29 and the sliding column 32, so that the steel wire rope thereon is cleaned in the industrial alcohol tank 13; It is convenient to more accurately measure the state of the steel wire rope;

[0046] Step 4: The rotating spline shaft sleeve 16 drives the spline shaft 17 to wind. Then, through the cooperation of the gear 18 and the teeth 26, the fourth disc 23 rotates. Then, through the cooperation of the second connecting rod 33 and the second hinge rod 34, the spline shaft 17 moves horizontally back and forth, causing the wire reel on the spline shaft 17 to wind the steel wire rope in multiple dimensions;

[0047] Step 5: When the eddy current detection device 7 detects a severely damaged steel wire rope, the power supply of the second motor 6 is started. The second motor 6 drives the first rotating column 9 and the third disc 10 to rotate. The circumferential third disc 10, through the cooperation of the first connecting rod 21 and the first hinge rod 11, causes the marking block 8 to mark the damaged steel wire rope.

[0048] Step 6: When releasing the steel wire rope, start the third motor 35, so that the first disc 4 and the second disc 5 cooperate to convey the steel wire rope.

[0049] Working principle: When personnel need to detect whether the steel wire rope is damaged, first, through the restraint of the first disc 4 and the second disc 5, the steel wire rope is smoothly transmitted, and the steel wire rope between the two groups of the first disc 4 and the second disc 5 is in a straight state. The eddy current detection device 7 is between the two transmission mechanisms, so that the eddy current detection device 7 can detect the steel wire rope in a straight state, thereby obtaining more accurate data. When the eddy current detection device 7 detects that the steel wire rope is severely damaged, start the second motor 6, so that the first rotating column 9 and the third disc 10 rotate circumferentially. The circumferentially rotating third disc 10, through the first connecting rod 21 and the first hinge rod 11, causes the marking block 8 to move horizontally. Here, the marking block 8 is connected to the eddy current detection device 7 in a limited sliding manner. The marking block 8 touches the steel wire rope to mark it.

[0050] Start the power supply of the first motor 2. The first motor 2 drives the spline shaft sleeve 16 to rotate. The rotating spline shaft sleeve 16 drives the spline shaft 17 to rotate. The spline shaft 17 drives the wire reel to rotate, thereby performing material collection. And the rotating spline shaft sleeve 16 drives the gear 18 to rotate. The gear 18, through the cooperation with the teeth 26, causes the fourth disc 23 to rotate. The rotating fourth disc 23, in cooperation with the second connecting rod 33 and the second hinge rod 34, causes the slider 15 to move horizontally back and forth. Thus, multi-dimensional winding is performed, and steel wire ropes of multiple widths are wound on the wire reel. Thus, more steel wire ropes can be wound on the wire reel, and it is more convenient for transportation.

[0051] The rotating spline shaft sleeve 16 causes the second rotating column 19 to rotate through the belt 22. The rotating second rotating column 19 drives the fifth disc 27 to rotate eccentrically, and then cooperates with the sliding frame 28, the connecting frame 29, and the sliding column 32 to cause the connecting frame 29 to swing continuously, so that the steel wire rope in the wire frame 31 is continuously brushed. This makes the detection of the steel wire rope more accurate and facilitates clean winding. Multiple such devices can be provided. When it is necessary to convey the steel wire rope away, the third motor 35 is started to cause the second disc 5 to rotate, and then through the cooperation of the first disc 4 and the second disc 5, the steel wire rope is conveyed smoothly therein.

[0052] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
