Description

Technical Field

[0001] This invention relates to the field of wire rope strength testing technology, specifically to a strength testing device for wire rope processing. Background Technology

[0002] In modern industrial production and engineering construction, steel wire ropes are widely used in many fields such as hoisting machinery, mining, bridge construction, and port loading and unloading due to their high strength, high toughness, and good wear resistance. The strength of steel wire ropes is directly related to operational safety and equipment reliability; therefore, accurate strength testing of steel wire ropes is a key step in ensuring their quality and safe use.

[0003] However, existing wire rope strength testing equipment still has certain shortcomings in use; A wire rope tensile strength testing device, as proposed in application number CN202411487079.5, includes a base. A vertical plate is fixedly mounted on the upper surface of the base, and a lower mounting block is fixedly mounted on the top of the vertical plate. A hydraulic telescopic cylinder is also fixedly mounted on the upper surface of the base, and a top plate is fixedly mounted on the telescopic end of the hydraulic telescopic cylinder. A movable plate is movably mounted through the outer wall of the top plate. A movable plate is fixedly mounted on the top of the movable plate, and an upper mounting block is fixedly mounted on the bottom of the movable plate. In the testing process, as the tension on the wire rope gradually increases, the pressure applied by the conical component to the conical opening also gradually increases. This makes the clamping force on the end of the wire rope proportional to the tension on the wire rope, effectively preventing slippage at the end of the wire rope that would prevent testing. Furthermore, the wire rope is easy to fix, resulting in better performance. However, in actual use, the following problems still exist: The wire rope tensile strength testing device uses protective components to surround the wire rope being tested, thereby preventing the wire rope from breaking and improving the safety of the device. However, a small amount of debris is generated during the wire rope breaking, and this debris will splash due to the force generated during the break. The wire rope tensile strength testing device cannot effectively collect and block the splashed debris, which reduces its practicality. The wire rope tensile strength testing device uses the rise of the hydraulic telescopic cylinder to cooperate with the clamp to drive the wire rope to perform tensile testing. However, this testing method can only test wire ropes of a specific length. When the length of the wire rope test sample is different, it needs to be cut, which reduces the adaptability of the testing work.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing warehouse shuttle vehicles. Summary of the Invention

[0005] The purpose of this invention is to provide a strength testing device for steel wire rope processing, in order to solve the problems mentioned in the background art. Although the existing protective components can protect broken steel wire ropes, they cannot effectively collect and block flying debris. Furthermore, the testing method relying on hydraulic telescopic cylinders and clamps is only applicable to specific lengths, and samples of different lengths need to be cut, resulting in low practicality and testing adaptability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a strength testing device for steel wire rope processing, comprising a base, a support seat fixedly installed on the top surface of the base, and an adjusting screw, the two ends of the adjusting screw being rotatably connected to the support seat, a rotating wheel fixedly installed on the top end of the adjusting screw, a lifting seat threaded on the outer ring of the adjusting screw, a hydraulic cylinder installed inside the lifting seat, and a tension sensor fixedly installed on the top surface of the base; The double-end clamping mechanism, located at the bottom of the hydraulic cylinder and the bottom of the tension sensor, is used to clamp and fix the two ends of the wire rope. A limiting seat is fixedly installed on the rear side of the support base; The opening and closing protective mechanism, located on both sides of the limit seat, is used for protection during wire rope inspection and for debris collection. The driven lubrication mechanism is installed in the middle of the rear side of the opening and closing protection mechanism for lubricating the connection between the lifting seat and the adjusting screw; A tensile testing mechanism, which is connected between a double-end clamping mechanism and a lifting seat, is used to test the elongation length of a wire rope when it is stretched.

[0007] Preferably, the double-ended clamping mechanism includes a connecting seat fixedly installed at the top of the tension sensor and the bottom of the hydraulic cylinder. A positioning seat is fixedly installed at one end of the connecting seat. A sliding groove is opened inside the positioning seat. A double-ended screw is arranged inside the sliding groove. The threads at both ends of the double-ended screw are arranged in opposite directions. The two ends of the double-ended screw are rotatably connected to the positioning seat. Adjusting wheels are fixedly installed at both ends of the double-ended screw.

[0008] Preferably, the double-end clamping mechanism further includes a movable plate symmetrically slidably disposed inside the slide groove. A clamping seat is fixedly installed on the inner side of the movable plate, and anti-slip strips are installed at equal intervals on the inner ring of the clamping seat. The cross-section of the anti-slip strips is designed in a triangular structure.

[0009] The above technical solution utilizes a double-end clamping mechanism that rotates an adjusting wheel to drive a double-end screw. The reverse thread structure allows the two movable plates to slide in opposite directions within the groove, achieving stable clamping of the wire rope. The triangular structure of the anti-slip strip increases friction with the wire rope surface, effectively preventing slippage during clamping. The rotation of the adjusting screw adjusts the height of the lifting seat and the upper double-end clamping mechanism. This solution specifically addresses the problem that traditional equipment is only suitable for wire ropes of specific lengths, requiring sample cutting. It eliminates the need to cut samples of different lengths, significantly improving the adaptability of the testing process and enhancing the stability and reliability of the clamping.

[0010] Preferably, the opening and closing protective mechanism includes positioning rods installed at equal intervals on both sides of the limiting seat. The outer ends of the positioning rods at the upper and lower ends are fixedly sleeved with retaining rings. The outer rings of the positioning rods on both sides are slidably sleeved with sliding plates. The front end of the sliding plate is fixedly connected with a protective cover. An electromagnetic suction plate is fixedly installed on the inner side of the protective cover.

[0011] Using the above technical solution, when the wire rope is being inspected, the protective cover can be opened and closed by sliding the sliding plate on the positioning rod to provide encircling protection for the wire rope; The electromagnetic chuck can attract metal fragments generated when a steel wire rope breaks, preventing fragments from flying and effectively collecting them. This design overcomes the shortcomings of traditional equipment in effectively collecting and blocking flying fragments, improving the safety and practicality of the equipment, and ensuring the safety of operators and a clean working environment.

[0012] Preferably, the driven lubrication mechanism includes a piston plate fixedly installed at the outer end of the positioning rod in the middle, a piston tube slidably sleeved on the outer ring of the piston plate, the front side of the piston tube being fixedly connected to a protective cover, and the opening and closing of the protective cover being positioned by the friction between the piston plate and the piston tube.

[0013] Preferably, the driven lubrication mechanism further includes a pressure relief valve installed at an equal angle on the inner end of the piston tube, and a one-way inlet valve and a one-way outlet valve installed on the outer end of the piston tube. The inlet end of the one-way inlet valve is fixedly connected to a connecting pipe, and the bottom end of the connecting pipe is fixedly connected to a storage tank. The bottom of the storage tank is fixedly connected to the base.

[0014] Preferably, the driven lubrication mechanism further includes a delivery pipe fixedly installed at the outlet end of the one-way discharge valve. A flow divider ring is fixedly connected to the outlet end of the delivery pipe. The bottom end of the flow divider ring is fixedly connected to the lifting seat. The flow divider ring is slidably sleeved with the adjusting screw. The opening at the bottom of the flow divider ring corresponds to the connection between the lifting seat and the adjusting screw.

[0015] Using the above technical solution, the driven lubrication mechanism utilizes the sliding of the piston plate in the piston tube when the protective cover is opened and closed to form a piston effect. The piston tube draws lubricating oil from the storage tank through the one-way inlet valve, and delivers it to the diversion ring through the one-way outlet valve and the delivery pipe. Finally, it lubricates the connection between the lifting seat and the adjusting screw, reducing friction and extending the service life of the equipment. Meanwhile, the opening and closing of the protective cover can be positioned by the friction between the piston plate and the piston tube, ensuring stable protection. This design not only solves the lubrication problem between equipment components, but also achieves reliable positioning of the protective mechanism, improving the overall performance and durability of the equipment.

[0016] Preferably, the tensile testing mechanism includes a limiting sleeve fixedly installed on the left side of the lifting seat, and a scale slides through the inside of the limiting sleeve, with the bottom end of the scale fixedly connected to the top surface of the connecting seat.

[0017] Using the above technical solution, the scale in the tensile testing mechanism can slide stably inside the limiting sleeve, and the elongation length of the wire rope during tension can be displayed intuitively by utilizing the gap inside the limiting sleeve, providing data reference for the testing personnel.

[0018] Preferably, the tensile testing mechanism includes a fixed rod fixedly installed on the left side of the lifting seat, a driven gear sleeved on the outer ring of the fixed rod, a pointer fixedly connected to the left side of the driven gear, mounting plates symmetrically installed at the front end of the lifting seat, a scale plate fixedly connected to the front end of the mounting plate, and a drive gear plate fixedly installed on the top left side of the connecting seat.

[0019] Preferably, the driven gear and the pointer are rotatably connected to the fixed rod, the drive gear plate is meshed with the driven gear, and the dial is arranged in an arc shape.

[0020] By adopting the above technical solution, the drive tooth plate meshes with the driven gear when it moves with the connecting seat, causing the pointer to rotate on the dial. This converts the tensile displacement of the wire rope into an angular change, effectively amplifying the spacing change proportionally and presenting the degree of wire rope tension in a more intuitive way. This design enables the monitoring of the wire rope tensioning process, facilitating a comprehensive assessment of wire rope quality. Compared with traditional testing methods, it provides richer and more intuitive testing data, improving testing efficiency.

[0021] Compared with existing technologies, the beneficial effects of this invention are as follows: This strength testing equipment for steel wire rope processing, through innovative multi-mechanism design, effectively solves the shortcomings of traditional equipment in terms of debris collection, sample adaptation, and testing and monitoring, significantly improving the equipment's practicality, testing efficiency, and reliability. The specific details are as follows: 1. The double-end clamping mechanism adopts a double-end screw and reverse thread structure, combined with a sliding movable plate and anti-slip strip, which can stably clamp steel wire ropes of different diameters and avoid slippage. At the same time, the height of the lifting seat can be adjusted by adjusting the screw, without cutting the sample, which greatly improves the adaptability of the testing work to steel wire ropes of different lengths and enhances the clamping stability and reliability. 2. The protective cover in the opening and closing protection mechanism can slide open and close to achieve the surrounding protection of the wire rope. The electromagnetic suction plate on its inner side can effectively absorb the debris generated by the wire rope breakage and prevent it from splashing. This solves the problem that traditional equipment cannot effectively collect and block debris, ensuring the safety of operators and the cleanliness of the working environment, and improving the safety and practicality of the equipment. 3. The driven lubrication mechanism utilizes the piston effect generated by the piston plate sliding inside the piston tube when the protective cover is opened and closed to realize the automatic delivery and circulation of lubricating oil, lubricate the connection between the lifting seat and the adjusting screw, reduce friction and extend the service life of the equipment, and the friction between the piston plate and the piston tube can be used for the positioning of the protective cover to ensure stable protection and improve the overall performance and durability of the equipment. 4. The scale in the tensile testing mechanism can intuitively display the tensile extension length of the wire rope. The cooperation between the drive tooth plate, driven gear, pointer and scale dial converts the tensile displacement into magnified angular changes, which more intuitively presents the degree of tension. The two testing methods realize real-time monitoring of the wire rope tensioning process, providing rich and intuitive data for comprehensive evaluation of wire rope quality. Compared with traditional testing methods, it significantly improves the accuracy and efficiency of testing. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figures 1-8 The present invention provides a technical solution: a strength testing device for steel wire rope processing, including a base 1, a support seat 2 fixedly installed on the top surface of the base 1, and an adjusting screw 3, the two ends of the adjusting screw 3 being rotatably connected to the support seat 2, a rotating wheel 4 fixedly installed on the top end of the adjusting screw 3, a lifting seat 5 threaded on the outer ring of the adjusting screw 3, a hydraulic cylinder 6 installed inside the lifting seat 5, and a tension sensor 7 fixedly installed on the top surface of the base 1; A double-end clamping mechanism is located at the bottom end of the hydraulic cylinder 6 and the bottom end of the tension sensor 7. It is used to clamp and fix the two ends of the wire rope. The double-end clamping mechanism includes a connecting seat 8 fixedly installed at the top end of the tension sensor 7 and the bottom end of the hydraulic cylinder 6. A positioning seat 9 is fixedly installed at one end of the connecting seat 8. A sliding groove 10 is opened inside the positioning seat 9. A double-end screw 11 is set inside the sliding groove 10. The threads at both ends of the double-end screw 11 are arranged in opposite directions. The two ends of the double-end screw 11 are rotatably connected to the positioning seat 9. Adjusting wheels 12 are fixedly installed at both ends of the double-end screw 11. The double-end clamping mechanism also includes a movable plate 13 symmetrically slidably arranged inside the sliding groove 10. A clamping seat 14 is fixedly installed on the inner side of the movable plate 13. Anti-slip strips 15 are installed at equal intervals on the inner ring of the clamping seat 14. The cross section of the anti-slip strips 15 is designed with a triangular structure. In the above technical solution, when using the double-end clamping mechanism of the strength testing equipment, the operator first rotates the adjusting wheel 12, which drives the double-end screw 11 to rotate in the positioning seat 9. Since the threads at both ends of the double-end screw 11 are set in opposite directions, when the double-end screw 11 rotates, it will drive the two movable plates 13 to slide in opposite directions in the slide groove 10. If it is necessary to clamp the wire rope, rotate the adjusting wheel 12 to make the two movable plates 13 slide in opposite directions. The movable plates 13 drive the inner clamping seat 14 to move closer until the wire rope is stably clamped between the two clamping seats 14. At this time, the triangular anti-slip strips 15 installed at equal intervals on the inner ring of the clamping seat 14, with their special shape and structure, are in close contact with the surface of the wire rope and increase the friction, effectively preventing the wire rope from slipping during the testing process. The connecting seat 8 at the top of the tension sensor 7 and the bottom of the hydraulic cylinder 6 serves to securely connect the positioning seat 9 to other components, ensuring the stability and reliability of the entire clamping process. At the same time, when it is necessary to test steel wire ropes of different lengths, the rotating wheel 4 can be rotated to drive the adjusting screw 3 to rotate, thereby enabling the lifting seat 5 to be threaded on the adjusting screw 3, thus realizing the adjustment of the height of the entire upper double-end clamping mechanism to adapt to steel wire rope samples of different lengths without the need for cutting.

[0026] A limiting seat 16 is fixedly installed on the rear side of the support base 2. An opening and closing protective mechanism is located on both sides of the limiting seat 16 for protection during wire rope detection and debris collection. The opening and closing protective mechanism includes positioning rods 17 installed at equal intervals on both sides of the limiting seat 16. A retaining ring 18 is fixedly sleeved on the outer end of the positioning rods 17 at both ends. A sliding plate 19 is slidably sleeved on the outer ring of the positioning rods 17 on both sides. A protective cover 20 is fixedly connected to the front end of the sliding plate 19. An electromagnetic suction plate 21 is fixedly installed on the inner side of the protective cover 20. The driven lubrication mechanism includes a piston plate 22 fixedly installed on the outer end of the middle positioning rod 17. A piston tube 23 is slidably sleeved on the outer ring of the piston plate 22. The front side of the piston tube 23 is fixedly connected to the protective cover 20. The opening and closing of the protective cover 20 is positioned by the friction between the piston plate 22 and the piston tube 23. In the above technical solution, when performing wire rope strength testing, the opening and closing protective mechanism is operated first. After the wire rope is installed into the double-end clamping mechanism, the protective covers 20 on both sides are pushed. Since the sliding plate 19 is sleeved on the outer ring of the positioning rod 17, it can slide along the positioning rod 17, so that the two protective covers 20 are close to each other and surround the outside of the wire rope testing area, thus completing the protection setting for the wire rope. The retaining rings 18 at the outer ends of the positioning rods 17 at both ends can limit the sliding range of the sliding plate 19 and prevent it from falling off the positioning rod 17. When the wire rope breaks during the inspection process, metal debris will be generated. At this time, the electromagnetic suction plate 21 inside the protective cover 20 is energized and generates magnetism, which can quickly attract the flying debris, prevent the debris from flying everywhere, effectively collect the debris, and ensure the safety of operators and the cleanliness of the working environment. During the opening and closing of the protective cover 20, the piston tube 23, which is fixedly connected to the front side of the protective cover 20, moves accordingly. The piston plate 22 inside the piston tube 23 slides relative to the piston tube 23, forming a piston effect. There is a certain friction between the piston plate 22 and the piston tube 23. This friction allows the protective cover 20 to be stably positioned after it is opened or closed to a suitable position, and it will not slide randomly, ensuring stable and reliable protection during the wire rope inspection process.

[0027] The driven lubrication mechanism is installed in the middle of the rear side of the opening and closing protection mechanism for lubricating the connection between the lifting seat 5 and the adjusting screw 3. The driven lubrication mechanism also includes a pressure relief valve 24 installed at an equal angle to the inner end of the piston tube 23. The outer end of the piston tube 23 is equipped with a one-way inlet valve 25 and a one-way outlet valve 26. The inlet end of the one-way inlet valve 25 is fixedly connected to a connecting pipe 27. The bottom end of the connecting pipe 27 is fixedly connected to a storage tank 28. The bottom of the storage tank 28 is fixedly connected to the base 1. The driven lubrication mechanism also includes a delivery pipe 29 fixedly installed at the outlet end of the one-way outlet valve 26. The outlet end of the delivery pipe 29 is fixedly connected to a diverter ring 30. The bottom end of the diverter ring 30 is fixedly connected to the lifting seat 5. The diverter ring 30 is slidably sleeved with the adjusting screw 3. The opening at the bottom of the diverter ring 30 corresponds to the connection between the lifting seat 5 and the adjusting screw 3. In the above technical solution, the driven lubrication mechanism converts the opening and closing kinetic energy of the protective cover 20 into lubrication power through ingenious mechanical linkage and fluid control; When the protective cover 20 and sliding plate 19 of the opening and closing protective mechanism slide along the positioning rod 17, the piston tube 23, which is fixedly connected to the front side of the protective cover 20, moves synchronously. Since the piston plate 22 is fixedly installed at the outer end of the middle positioning rod 17, the piston tube 23 will slide relative to the piston plate 22, forming a piston effect. When the piston tube 23 slides away from the limit seat 16, the internal volume of the piston tube 23 increases and the pressure decreases. At this time, under the action of the external atmospheric pressure, the lubricating oil in the storage tank 28 enters the piston tube 23 through the connecting pipe 27, opening the one-way inlet valve 25. The one-way conduction characteristic of the one-way inlet valve 25 ensures that the lubricating oil can only flow from the storage tank 28 into the piston tube 23, preventing backflow. When the piston tube 23 slides closer to the limit seat 16, the internal volume of the piston tube 23 decreases and the pressure increases. At this time, the lubricating oil is squeezed and opens the one-way discharge valve 26, flowing into the diverter ring 30 through the delivery pipe 29. The one-way discharge valve 26 also has one-way conduction, ensuring that the lubricating oil can only flow from the piston tube 23 to the diverter ring 30. The diverter ring 30 is fixedly connected to the lifting seat 5 and sleeved on the adjusting screw 3. Its bottom opening corresponds to the connection between the lifting seat 5 and the adjusting screw 3. The lubricating oil flowing into the diverter ring 30 drips evenly through the bottom opening onto the threaded connection between the lifting seat 5 and the adjusting screw 3, lubricating both of them. This effectively reduces the friction generated when the lifting seat 5 is threaded on the adjusting screw 3, reduces component wear, and extends the service life of the equipment.

[0028] The tensile testing mechanism is connected between the double-end clamping mechanism and the lifting seat 5 to test the elongation length of the wire rope when it is stretched. The tensile testing mechanism includes a limiting sleeve 31 fixedly installed on the left side of the lifting seat 5. A scale 32 slides through the inside of the limiting sleeve 31. The bottom end of the scale 32 is fixedly connected to the top surface of the connecting seat 8. In the above technical solution, when the strength of the wire rope is tested, when the hydraulic cylinder 6 is started, it drives the upper double-end clamping mechanism connected to it to move upward, applying tension to the wire rope. The wire rope begins to be stretched. At this time, the scale 32, which is fixedly connected to the top surface of the connecting seat 8, will move together with the connecting seat 8. Since the scale 32 slides through the inside of the limiting sleeve 31, the limiting sleeve 31 plays a guiding and limiting role, ensuring that the scale 32 can only slide stably along its axial direction, avoiding deviation or shaking. As the wire rope is stretched, the connecting seat 8 drives the scale 32 to slide continuously upward in the limiting sleeve 31. The length of the scale 32 exposed relative to the limiting sleeve 31 gradually increases. Then, the length of the wire rope extended during the stretching process can be directly read by observing the scale on the scale 32.

[0029] Example 2: Based on Example 1, the present invention adopts the following... Figures 9-10 The technical solution shown further discloses that the tensile testing mechanism includes a fixed rod 33 fixedly installed on the left side of the lifting seat 5, a driven gear 34 sleeved on the outer ring of the fixed rod 33, a pointer 35 fixedly connected to the left side of the driven gear 34, an mounting plate 36 symmetrically installed at the front end of the lifting seat 5, a scale 37 fixedly connected to the front end of the mounting plate 36, a drive gear plate 38 fixedly installed on the top left side of the connecting seat 8, the driven gear 34 and the pointer 35 are rotatably connected to the fixed rod 33, the drive gear plate 38 is meshed with the driven gear 34, and the scale 37 is arranged in an arc shape. In the above technical solution, when the hydraulic cylinder 6 is started, it drives the upper double-end clamping mechanism connected to it to move upward, and applies tension to the wire rope clamped in the double-end clamping mechanism. The wire rope begins to be stretched, and the drive tooth plate 38, which is fixedly connected to the connecting seat 8, moves upward together with the connecting seat 8. Because the drive gear plate 38 is meshed with the driven gear 34, when the drive gear plate 38 moves upward, its teeth push the driven gear 34 to rotate around the fixed rod 33. The pointer 35, which is fixedly connected to the left side of the driven gear 34, will rotate synchronously with the driven gear 34. Since the scale 37 is fixedly installed at the front end of the mounting plate 36 and has an arc-shaped structure that matches the rotation path of the pointer 35, as the wire rope is continuously stretched, the drive gear plate 38 continues to move upward, and the driven gear 34 drives the pointer 35 to slide across a larger angle on the scale 37. By observing the scale indicated by the pointer 35 on the scale 37, the inspector can intuitively obtain the angle change data after the wire rope's tensile displacement, thus more clearly and accurately judging the degree of tension of the wire rope.
