Description

Technical Field

[0001] The invention relates to the field of detection technology, in particular to a corrosion resistance detection device for steel wire rope production and processing. Background Art

[0002] In modern industrial production and infrastructure construction, wire ropes are an indispensable key component and are widely used in many fields such as lifting, hoisting, bridges, and mines. The quality of their performance, especially their corrosion resistance, is directly related to the safety and service life of equipment operation, as well as the quality and reliability of engineering projects.

[0003] In the prior art, in terms of simulating the actual stress state of wire ropes, most of the existing testing equipment can only simulate tensile stress or bending stress separately, and cannot simultaneously simulate the complex stress state of wire ropes that are both stretched and bent in actual use. However, in actual working conditions, wire ropes are often subjected to the combined effects of multiple stresses such as stretching and bending at the same time. This single stress simulation testing method makes the test results far from the actual situation, and cannot provide a comprehensive and accurate reference for the selection, design and use of wire ropes. Summary of the invention

When the wire rope passes around the guide wheel, bending stress is generated. Combined with the tensile force applied by the hanging counterweight, the complex stress state of the wire rope in actual use, which is both stretched and bent, can be simulated at the same time.

[0011] Preferably, the outer wall of the pull rod is slidably connected to the bottom of the inner wall of the detection box, the outer side of the plug block is slidably connected to the inner wall of the fixed frame, and the top of the variable spring is fixedly connected to the bottom of the fixed frame. Under the tension of the wire rope, the guide wheel drives the wheel frame to slide along the inner side of the fixed frame, and at the same time, the plug block moves with the wheel frame and forces the variable spring to be compressed. At this time, the plug block can block the opening of the fixed frame to prevent the wire rope from detaching from the surface of the guide wheel.

[0012] Preferably, the top of the limit frame is fixedly connected to the bottom of the inner wall of the detection box, the outer wall of the roller is rollingly connected to the inner side of the limit frame, and the outer side of the diffusion component is fixedly connected to both sides of the fixed component.

When the adjusting bolt is rotated, the sliding block can be driven to move up and down in the fixed cylinder. At this time, the sliding block can drive the sliding rod to move up and down together through the compression spring. In the process of the sliding rod moving up and down, the limit block moves up and down synchronously and slides in the long hole opened on the surface of the limit rod, thereby causing the limit rod to deflect in the shell.

[0017] Preferably, the bottom of the fixed cylinder is fixedly connected to the top of the shell, the outer side of the fixed cylinder is fixedly connected to the center of the sliding frame, the side walls of the sliding block and the sliding rod are both slidably connected to the inner wall of the fixed cylinder, and the outer side of the limit block is slidably connected to the inner wall of the limit rod.

[0020] (III) Beneficial effects

[0021] The present invention provides a corrosion resistance testing device for steel wire rope production and processing, which has the following beneficial effects:

[0022] (I) The device is provided with a tension adjustment component. When the adjusting bolt is rotated, the adjusting bolt can drive the sliding block to move up and down in the fixed cylinder. At this time, the sliding block can drive the sliding rod to move up and down together through the compression spring. In the process of the sliding rod moving up and down, the limit block moves up and down synchronously and slides in the long hole opened on the surface of the limit rod, thereby causing the limit rod to deflect in the shell. At this time, the arc rods on both sides can deflect in the opposite direction relative to the limit rod, thereby adjusting the positions of the two clamping components to meet the detection requirements of steel wire ropes of different specifications, ensuring that the tension applied to the steel wire rope is more uniform and stable.

[0023] (ii) The device is equipped with a compression spring, which can play a role of buffering and shock absorption during the tension adjustment process. When the sliding block moves the compression spring downward, the spring will absorb a certain amount of energy to avoid damage to the wire rope caused by sudden excessive force. At the same time, during the operation of the equipment, some vibration and impact force may be generated. The compression spring can effectively reduce the impact of these forces on the wire rope and the entire detection system, ensuring the stability and reliability of the detection process.

[0024] (III) The device is provided with a clamping component. When the clamping component is used to fix the two ends of the wire rope, the end part of the wire rope is first placed between the clamping plates along the arc guide plate. At this time, the threaded column is rotated to make the slider slide upward along the inner wall of the fixed shell. At this time, the limit wheel and the arc block squeeze each other, and force the bottom of the clamping plate to shrink inward, and clamp the wire rope to prevent the wire rope from slipping during the application of tension and subsequent tests.

[0025] (IV) The equipment is provided with a bending and stretching device, and the middle position of the wire rope is passed through the opening of the fixed frame and the plug block so that it is sleeved on the surface of the guide wheel. By hanging a counterweight block on the surface of the lifting ring, a downward pulling force is applied to the wire rope to simulate the tensile stress to which the wire rope is subjected in actual use. When the wire rope passes around the guide wheel, bending stress is generated. Combined with the tensile force applied by the hanging counterweight block, the complex stress state of the wire rope in actual use, which is both stretched and bent, can be simulated at the same time, thereby more realistically restoring the stress conditions of the wire rope under various working conditions.

[0026] (V) The device is provided with an insert block. After the counterweight block is hung, the counterweight block pulls the pull rod and the fixed frame downward through the lifting ring under the action of gravity. At this time, under the tension of the wire rope, the guide wheel drives the wheel frame to slide along the inner side of the fixed frame. At the same time, the insert block moves with the wheel frame and forces the variable diameter spring to be compressed. At this time, the insert block can block the opening of the fixed frame to prevent the wire rope from detaching from the surface of the guide wheel.

[0027] (VI) The equipment is provided with a diffusion component, and the salt water flows into the liquid guide tube of the diffusion component through a hose. The liquid in the liquid guide tube drives the guide fan on the outside of the rotating shaft to rotate, driving the flow-breaking plate at the bottom of the rotating shaft to rotate. At this time, the liquid continues to flow, pushing the sealing block to overcome the resistance of the reset spring and slide downward, opening the liquid inlet hole in the nozzle wall, and the liquid is sprayed out from the nozzle, and then it is broken up by the rotation of the flow-breaking plate, forming fine droplets to simulate a uniform salt spray environment.

[0028] (VII) The equipment is equipped with a flow-breaking fan. In actual applications, the wire rope is usually exposed to an environment with a certain amount of airflow, and the salt spray is also in a dynamic state. The flow-breaking plate tilts and rotates to drive the air flow, which can highly simulate this real airflow state. This makes the detection environment closer to the actual working scene of the wire rope, and the test results can better reflect its corrosion resistance in the real environment, thereby improving the accuracy and reliability of the test.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0040] The salt spray generating device 4 comprises a limit frame 41, the inner side of the limit frame 41 is slidably connected to a sliding frame 42, both sides of the sliding frame 42 are rotatably connected to rollers 43, the center of the sliding frame 42 is fixedly connected to a fixing assembly 44, both sides of the sliding frame 42 are fixedly connected to a brine tank 45, the bottom of the brine tank 45 is fixedly connected to a hose 46, and the bottom end of the hose 46 is fixedly connected to a diffusion component 47; the top of the limit frame 41 is fixedly connected to the bottom of the inner wall of the detection box 1, the outer wall of the roller 43 is rollingly connected to the inner side of the limit frame 41, and the outer side of the diffusion component 47 is fixedly connected to both sides of the fixing assembly 44, After opening the box door 2, first slide the sliding frame 42 out from the inner side of the limit frame 41, and the roller 43 reduces the friction resistance of the sliding frame 42 when sliding. At this time, the two ends of the wire rope can be fixed by the fixing component 44. After being fixed, the sliding frame 42 is reset and the box door 2 is closed. At this time, the booster valve at the bottom of the salt water tank 45 is opened, and the salt water inside the salt water tank 45 can enter the diffusion component 47 through the hose 46, and finally sprayed on the surface of the wire rope. At this time, the corrosion resistance of the wire rope under salt spray corrosion conditions can be judged by observing the time and degree of corrosion on the surface of the wire rope.

[0041] The fixing assembly 44 includes a shell 441, the top of which is fixedly connected to a tension adjusting component 442, the inner side of the shell 441 is symmetrically rotationally connected to an arc rod 443, the bottom end of the arc rod 443 is rotationally connected to a clamping component 444, and the top of the arc rod 443 is fixedly connected to a limiting rod 445; the top of the shell 441 is fixedly connected to the bottom of the sliding frame 42, the center of the sliding frame 42 is fixedly connected to the outer side of the tension adjusting component 442, the inner side of the arc rod 443 is fixedly connected to the outer side of the diffusion component 47, and when the limiting rod 445 is deflected in the shell 441, the arc rods 443 on both sides can be deflected in the opposite direction relative to the limiting rod 445, thereby adjusting the positions of the two clamping components 444 to meet the detection requirements of steel wire ropes of different specifications and ensure that the tension applied to the steel wire rope is more uniform and stable.

[0042] The bending and stretching device 5 includes a fixed frame 51, the inner side of the fixed frame 51 is slidably connected to a wheel frame 52, the inner side of the wheel frame 52 is rotatably connected to a guide wheel 53, the bottom of the wheel frame 52 is fixedly connected to an insert block 54, the inner side of the insert block 54 is fixedly connected to a variable diameter spring 55, the bottom of the fixed frame 51 is fixedly connected to a pull rod 56, the bottom end of the pull rod 56 is fixedly connected to a hanging ring 57, the outer wall of the pull rod 56 is slidably connected to the bottom of the inner wall of the detection box 1, the outer side of the insert block 54 is slidably connected to the inner wall of the fixed frame 51, and the top of the variable diameter spring 55 is fixedly connected to the bottom of the fixed frame 51. When the wire rope is placed in the detection box 1, the pull rod 56 can be pushed upward to adjust the height of the fixed frame 51 in the detection box 1, and then the middle position of the wire rope is passed through the opening of the fixed frame 51 and the insert block 54 to make it sleeved on the surface of the guide wheel 53. At this time, it can be lifted by the lifting ring 57. A counterweight is hung on the surface of the ring 57 to apply a downward pulling force to the wire rope, simulating the tensile stress that the wire rope is subjected to in actual use. When the wire rope passes around the guide wheel 53, bending stress is generated. Combined with the tensile force applied by the hanging counterweight, the complex stress state of the wire rope being subjected to both tension and bending in actual use can be simulated at the same time, thereby more realistically restoring the stress conditions of the wire rope under various working conditions. After the counterweight is hung, the counterweight pulls the pull rod 56 and the fixing frame 51 downward through the hanging ring 57 under the action of gravity. At this time, under the action of the tension of the wire rope, the guide wheel 53 drives the wheel frame 52 to slide along the inner side of the fixing frame 51, and the insert block 54 moves with the wheel frame 52 and forces the variable diameter spring 55 to be compressed. At this time, the insert block 54 can block the opening of the fixing frame 51 to prevent the wire rope from detaching from the surface of the guide wheel 53.

[0043] The clamping component 444 includes a fixed shell 401, the top of the fixed shell 401 is rotatably connected to a threaded column 402, the outer wall of the threaded column 402 is threadedly connected to a slider 403, the slider 403 is rotatably connected to a clamping plate 404, the outer side of the clamping plate 404 is fixedly connected to an arc block 406, the bottom of the clamping plate 404 is fixedly connected to an arc guide plate 407, the outer side of the fixed shell 401 is rotatably connected to a limiting wheel 405, the outer side of the fixed shell 401 is rotatably connected to the bottom of the arc rod 443, the outer side of the slider 403 is connected to The inner wall of the fixed shell 401 is slidably connected, the outer side of the limiting wheel 405 contacts the outer side of the arc block 406, and the end part of the wire rope is placed between the clamping plates 404 along the arc guide plate 407. At this time, the threaded column 402 is rotated to make the slider 403 slide upward along the inner wall of the fixed shell 401. At this time, the limiting wheel 405 and the arc block 406 squeeze each other, and force the bottom of the clamping plate 404 to shrink inward, and clamp the wire rope to prevent the wire rope from slipping during the application of tension and subsequent experiments.

[0044] The tension adjustment component 442 includes a fixed cylinder 421, the top of the fixed cylinder 421 is rotatably connected to an adjusting bolt 422, the outer wall of the adjusting bolt 422 is threadedly connected to a sliding block 423, the bottom of the sliding block 423 is fixedly connected to a compression spring 424, the bottom end of the compression spring 424 is fixedly connected to a sliding rod 425, the bottom of the sliding rod 425 is fixedly connected to a limiting block 426, the bottom of the fixed cylinder 421 is fixedly connected to the top of the shell 441, the outer side of the fixed cylinder 421 is fixedly connected to the center of the sliding frame 42, the side walls of the sliding block 423 and the sliding rod 425 are both slidably connected to the inner wall of the fixed cylinder 421, and the limiting block 426 is fixedly connected to the bottom of the fixed cylinder 421. The outer side of the block 426 is slidably connected with the inner wall of the limit rod 445. When the adjusting bolt 422 in the tension adjustment component 442 is rotated, the adjusting bolt 422 can drive the sliding block 423 to move up and down in the fixed cylinder 421. At this time, the sliding block 423 can drive the sliding rod 425 to move up and down together through the compression spring 424. During the up and down movement of the sliding rod 425, the limit block 426 moves up and down synchronously and slides in the long hole opened on the surface of the limit rod 445, thereby causing the limit rod 445 to deflect in the housing 441. The compression spring 424 can play a role of buffering and shock absorption in the tension adjustment process. When the sliding block 423 moves the compression spring 424 downward, the spring will absorb a certain amount of energy to avoid sudden excessive force from causing damage to the wire rope. At the same time, during the operation of the equipment, some vibration and impact force may be generated. The compression spring 424 can effectively reduce the impact of these forces on the wire rope and the entire detection system, ensuring the stability and reliability of the detection process.

[0045] The diffusion component 47 includes a liquid guiding cylinder 471, the inner side of which is rotatably connected to a rotating shaft 472, the outer side of which is fixedly connected to a guide fan 473, the bottom of which is fixedly connected to a flow-breaking plate 474, the inner wall of the liquid guiding cylinder 471 is fixedly connected to a nozzle 475, the outer wall of the nozzle 475 is slidably connected to a sealing block 476, the bottom of the sealing block 476 is fixedly connected to a return spring 477, the outer wall of the liquid guiding cylinder 471 is fixedly connected to the inner wall of the arc rod 443, the top of the liquid guiding cylinder 471 is fixedly connected to the bottom end of the hose 46, the outer wall of the sealing block 476 is slidably connected to the inner wall of the liquid guiding cylinder 471, the bottom end of the return spring 477 is fixedly connected to the bottom of the inner wall of the liquid guiding cylinder 471, a liquid inlet hole 478 is opened in the wall of the nozzle 475, and saline flows into the liquid guiding cylinder 471 of the diffusion component 47 through the hose 46. The liquid in the liquid guide cylinder 471 drives the guide fan 473 on the outside of the rotating shaft 472 to rotate, driving the flow-breaking plate 474 at the bottom of the rotating shaft 472 to rotate. At this time, the liquid continues to flow, pushing the sealing block 476 to overcome the resistance of the reset spring 477 and slide downward, opening the liquid inlet hole 478 in the wall of the nozzle 475, and the liquid is sprayed out from the nozzle 475, and then it is broken up by the rotation of the flow-breaking plate 474, forming fine droplets to simulate a uniform salt spray environment. In practical applications, the wire rope is usually exposed to an environment with a certain amount of air flow, and the salt spray is also in a dynamic change. The flow-breaking plate 474 tilts and rotates to drive the air flow, which can highly simulate this real air flow state. Make the detection environment closer to the actual working scene of the wire rope, so that the detection results can better reflect its corrosion resistance in the real environment, improve the accuracy and reliability of the detection, when the salt water stops flowing or the pressure decreases, the reset spring 477 will push the sealing block 476 to slide upward, close the liquid inlet hole 478, and stop the salt spray.

[0046] Working principle:

[0047] When in use, the support legs 3 are used to ensure the stable placement of the detection box 1, and then the box doors 2 on both sides of the detection box 1 are opened, and the two ends of the steel wire rope are fixed on the salt spray generating device 4, and then the middle position of the steel wire rope is fixed to the bending and stretching device 5 to complete the fixing process before the test, and finally the corrosion resistance of the steel wire rope can be tested by the salt spray generating device 4;

[0048] After opening the box door 2, first slide the sliding frame 42 out from the inner side of the limit frame 41, and the roller 43 reduces the friction resistance of the sliding frame 42 when sliding. At this time, the two ends of the wire rope can be fixed by the fixing component 44. After being fixed, the sliding frame 42 is reset and the box door 2 is closed. At this time, the boost valve at the bottom of the brine tank 45 is opened, and the brine inside the brine tank 45 can enter the diffusion component 47 through the hose 46, and finally sprayed on the surface of the wire rope. At this time, the corrosion resistance of the wire rope under salt spray corrosion conditions can be judged by observing the time and degree of corrosion on the surface of the wire rope.

[0049] When the adjusting bolt 422 in the tension adjusting component 442 is rotated, the adjusting bolt 422 can drive the sliding block 423 to move up and down in the fixed cylinder 421. At this time, the sliding block 423 can drive the sliding rod 425 to move up and down together through the compression spring 424. In the process of the sliding rod 425 moving up and down, the limit block 426 moves up and down synchronously and slides in the long hole opened on the surface of the limit rod 445, so that the limit rod 445 is deflected in the shell 441. At this time, the arc rods 443 on both sides can deflect in the opposite direction relative to the limit rod 445, so that the positions of the two clamping components 444 can be adjusted to meet the detection requirements of steel wire ropes of different specifications, so as to ensure that the tension applied to the steel wire rope is more uniform and stable.

[0050] The compression spring 424 can play a role of buffering and shock absorption during the tension adjustment process. When the sliding block 423 moves the compression spring 424 downward, the spring will absorb a certain amount of energy to avoid damage to the wire rope caused by sudden excessive force. At the same time, during the operation of the equipment, some vibration and impact force may be generated. The compression spring 424 can effectively reduce the impact of these forces on the wire rope and the entire detection system, ensuring the stability and reliability of the detection process.

[0051] When the two ends of the steel wire rope are fixed by the clamping member 444, the end of the steel wire rope is first placed between the clamping plates 404 along the arc-shaped guide plate 407. At this time, the threaded column 402 is rotated to make the slider 403 slide upward along the inner wall of the fixed shell 401. At this time, the limit wheel 405 and the arc-shaped block 406 squeeze each other and force the bottom of the clamping plate 404 to shrink inward, and clamp the steel wire rope to prevent the steel wire rope from slipping during the application of tension and subsequent tests.

[0052] When the steel wire rope is placed in the detection box 1, the pull rod 56 can be pushed upward to adjust the height of the fixing frame 51 in the detection box 1, and then the middle position of the steel wire rope is passed through the opening between the fixing frame 51 and the plug block 54 to make it sleeved on the surface of the guide wheel 53. At this time, a counterweight block can be hung on the surface of the ring 57 to apply a downward pulling force to the steel wire rope to simulate the tensile stress of the steel wire rope in actual use. When the steel wire rope passes around the guide wheel 53, bending stress will be generated. Combined with the tensile force applied by the hanging counterweight block, the complex stress state of the steel wire rope in actual use, which is both stretched and bent, can be simulated at the same time, thereby more realistically restoring the stress conditions of the steel wire rope under various working conditions.

[0053] After the counterweight is hung, the counterweight pulls the pull rod 56 and the fixed frame 51 downward through the lifting ring 57 under the action of gravity. At this time, under the tension of the wire rope, the guide wheel 53 drives the wheel frame 52 to slide along the inner side of the fixed frame 51. At the same time, the insert block 54 moves with the wheel frame 52 and forces the variable diameter spring 55 to be compressed. At this time, the insert block 54 can block the opening of the fixed frame 51 to prevent the wire rope from detaching from the surface of the guide wheel 53.

[0054] When the diffusion component 47 is in use, salt water flows into the liquid guide tube 471 of the diffusion component 47 through the hose 46. The liquid in the liquid guide tube 471 drives the guide fan 473 on the outside of the rotating shaft 472 to rotate, driving the flow-breaking plate 474 at the bottom of the rotating shaft 472 to rotate. At this time, the liquid continues to flow, pushing the sealing block 476 to overcome the resistance of the return spring 477 and slide downward, opening the liquid inlet hole 478 in the wall of the nozzle 475, and the liquid is sprayed out from the nozzle 475, and then the flow-breaking plate 474 rotates and is broken up to form fine droplets to simulate a uniform salt spray environment.

[0055] In actual applications, the wire rope is usually exposed to an environment with a certain amount of airflow, and the salt spray is also in a dynamic state. The flow-breaking plate 474 tilts and rotates to drive the air flow, which can highly simulate this real airflow state. This makes the detection environment closer to the actual working scene of the wire rope, and the detection results can better reflect its corrosion resistance in the real environment, improving the accuracy and reliability of the detection. When the salt water stops flowing or the pressure decreases, the reset spring 477 will push the sealing block 476 to slide upward, close the liquid inlet 478, and stop the salt spray.
