Description

Technical Field

[0001] This invention relates to the field of fiber rope testing, and more particularly to a device for testing ultra-high molecular weight polyethylene fiber ropes. Background Technology

[0002] Ultra-high molecular weight polyethylene (UHMWPE) ropes are commonly used in heavy-duty, high-friction environments, and abrasion resistance is one of their key properties. UHMWPE fiber ropes are lightweight, high-strength, abrasion-resistant, and corrosion-resistant, and are widely used in shipping, marine engineering, and petrochemical industries.

[0003] Existing methods for testing ultra-high molecular weight polyethylene (UHMWPE) fiber ropes typically involve winding the UHMWPE fiber rope around a metal cylinder and bringing it into contact with a friction surface. A certain force and speed are then applied to induce friction, and the wear resistance is assessed by observing the degree of wear on the UHMWPE fiber rope surface. However, the friction conditions of UHMWPE fiber ropes in actual use are caused by multiple factors. Therefore, applying a certain force and speed to rub the UHMWPE fiber rope makes the wear resistance test insufficiently comprehensive. Furthermore, multi-angle testing of the UHMWPE fiber rope is rarely performed, resulting in inadequate wear resistance testing and inaccurate results. Summary of the Invention

[0004] To overcome the shortcomings of existing UHMWPE fiber rope testing devices, which are insufficient in comprehensively testing the abrasion resistance of UHMWPE fiber ropes and rarely perform multi-angle simulation testing, resulting in inadequate abrasion resistance testing and inaccurate results, this invention provides an UHMWPE fiber rope testing device that can swing and tighten the UHMWPE fiber rope for more comprehensive abrasion resistance testing, and can also rotate the UHMWPE fiber rope for multi-angle testing, thus making the abrasion resistance testing of UHMWPE fiber ropes more accurate.

[0005] The technical solution of the present invention is as follows: a detection device for ultra-high molecular weight polyethylene fiber rope, comprising a base, a bracket fixedly connected to the base, a fixed platform fixedly connected to the middle of the bracket, a placement mechanism provided on the fixed platform, an ultra-high molecular weight polyethylene fiber rope provided on the placement mechanism, the placement mechanism being used to place the ultra-high molecular weight polyethylene fiber rope, and a swing mechanism provided on the placement mechanism, the swing mechanism being used to drive the ultra-high molecular weight polyethylene fiber rope to swing.

[0006] As a preferred embodiment of the present invention, the placement mechanism includes fixed support plates. Fixed support plates are fixedly connected to both sides of the fixed platform. A friction plate is fixedly connected between the ends of the two fixed support plates away from the fixed platform. The friction plate is provided with a friction surface. An upper fixed ball table is rotatably connected to the upper part of the fixed platform. Two guide plates are fixedly connected to one side of the lower part of the fixed platform. Each of the two guide plates has a sliding groove. A sliding seat is slidably connected to the sliding groove of each of the two guide plates. A moving rod is slidably connected to each of the two sliding seats. A pull ring is fixedly connected between the two moving rods. A lower fixed ball table is rotatably connected to the pull ring. An ultra-high molecular weight polyethylene fiber rope is wound between the upper fixed ball table and the lower fixed ball table. The ultra-high molecular weight polyethylene fiber rope passes around the friction surface of the friction plate.

[0007] As a preferred embodiment of the present invention, the swing mechanism includes a bidirectional motor, a power shaft fixedly connected to the output shaft at the lower part of the bidirectional motor, a rotating handle fixedly connected to the power shaft, a rotating bolt rotatably connected to the bottom of the fixed platform, a swing plate fixedly connected to the rotating bolt, transverse grooves on both sides of the swing plate, the transverse groove of the swing plate near the rotating handle being slidably connected to the rotating handle, and a swing rod fixedly connected to the bottom of the pull ring, the swing rod being slidably connected to the transverse groove of the swing plate away from the rotating handle.

[0008] As a preferred embodiment of the present invention, a rotating mechanism is further included. The upper fixed ball platform is provided with a rotating mechanism for rotating the ultra-high molecular weight polyethylene fiber rope. The rotating mechanism includes an inclined plate, which is fixedly connected to the middle of the fixed platform. A drive shaft is rotatably connected to the inclined plate. A universal coupling is connected between the lower end of the drive shaft and the output shaft of the bidirectional motor. The same universal coupling is also connected between the upper end of the drive shaft and the upper fixed ball platform. Drive wheels are fixedly connected to both the upper and lower fixed ball platforms, and a drive rope is wound between the two drive wheels.

[0009] As a preferred embodiment of the present invention, the transmission rope is in an interlaced shape and wound around the two transmission wheels.

[0010] As a preferred embodiment of the present invention, a tensioning mechanism is further included. The tensioning mechanism is disposed on the two sliding seats and is used to tension the ultra-high molecular weight polyethylene fiber rope. The tensioning mechanism includes a triangular rod, which is fixedly connected between the two sliding seats. A rotating shaft is rotatably connected to the fixed platform. A half-tooth gear is fixedly connected to the lower part of the rotating shaft. The half-tooth gear has two slots and a protrusion. A sector gear is fixedly connected to the rotating bolt and meshes with the half-tooth gear. A locking rod is slidably connected to the fixed platform. A compression spring is connected between the locking rod and the fixed platform. A sector disc is fixedly connected to the upper part of the rotating shaft. A torsion spring is connected between the sector disc and the fixed platform. The torsion spring is used for resetting. The sector disc contacts the triangular rod.

[0011] As a preferred embodiment of the present invention, it further includes a limiting cover, which is fixedly connected to the friction surface of the friction plate.

[0012] Beneficial effects: 1. By fixing the upper ball table, the lower ball table, and the friction plate, the ultra-high molecular weight polyethylene fiber rope is arranged in an arc shape, which allows the ultra-high molecular weight polyethylene fiber rope to fully contact the friction surface of the friction plate. This causes the ultra-high molecular weight polyethylene fiber rope to swing back and forth against the friction surface of the friction plate, thereby simulating the friction scenario of the ultra-high molecular weight polyethylene fiber rope in actual use, and thus testing the wear resistance of the ultra-high molecular weight polyethylene fiber rope.

[0013] 2. The transmission rope drives the upper fixed ball table to rotate forward and the lower fixed ball table to rotate in reverse, so that the entire UHMWPE fiber rope rotates but is not twisted. This allows the friction surface of the friction plate to rub the entire UHMWPE fiber rope from multiple directions and angles, thus enabling a comprehensive friction test on the UHMWPE fiber rope and more accurate test results for its wear resistance.

[0014] 3. By pulling one end of the ultra-high molecular weight polyethylene (UHMWPE) fiber rope, the UHMWPE fiber rope is taut, thus creating friction. The taut UHMWPE fiber rope is then rotated by the upper and lower fixed ball tables, and the pull ring causes the UHMWPE fiber rope to swing back and forth. This comprehensively improves the friction test of the UHMWPE fiber rope, making the test results more obvious. Simultaneously, the limiting cap can limit the movement of the UHMWPE fiber rope, ensuring stable friction between the UHMWPE fiber rope and the friction surface of the friction plate, thus making the abrasion resistance test results of the UHMWPE fiber rope more accurate.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0024] Example 1: A device for detecting ultra-high molecular weight polyethylene fiber rope, such as... Figures 1-4As shown, it includes a base 1, a bracket 2 fixedly connected to the base 1, a fixed platform 3 welded to the middle of the bracket 2, a placement mechanism on the fixed platform 3, an ultra-high molecular weight polyethylene fiber rope 49 on the placement mechanism, the placement mechanism is used to place the ultra-high molecular weight polyethylene fiber rope 49, and a swing mechanism on the placement mechanism is used to drive the ultra-high molecular weight polyethylene fiber rope 49 to swing.

[0025] The placement mechanism includes fixed support plates 41. Fixed support plates 41 are welded to both sides of the fixed platform 3. A friction plate 42 is welded between the ends of the two fixed support plates 41 away from the fixed platform 3. The friction plate 42 has a friction surface. An upper fixed ball table 43 is rotatably connected to the upper part of the fixed platform 3. Two guide plates 44 are welded to one side of the lower part of the fixed platform 3. Each guide plate 44 has a sliding groove, and a sliding seat 45 is slidably connected to the sliding groove of each guide plate 44. Each seat 45 has a sliding rod 46, and a pull ring 47 is welded between two of the sliding rods 46. A lower fixed ball table 48 is rotatably connected to the pull ring 47. The pull ring 47 is used to pull the lower fixed ball table 48. A high molecular weight polyethylene fiber rope 49 is wound between the upper fixed ball table 43 and the lower fixed ball table 48. The high molecular weight polyethylene fiber rope 49 passes around the friction surface of the friction plate 42, and the friction surface of the friction plate 42 is used to rub the high molecular weight polyethylene fiber rope 49.

[0026] The swing mechanism includes a bidirectional motor 51, a power shaft 52 fixedly connected to the output shaft at the lower part of the bidirectional motor 51, a rotating handle 53 fixedly connected to the power shaft 52, a rotating bolt 531 rotatably connected to the bottom of the fixed platform 3, a swing plate 54 welded to the rotating bolt 531, a transverse groove on both sides of the swing plate 54, the rotating handle 53 is used to push the swing plate 54 to swing, the transverse groove of the swing plate 54 near the rotating handle 53 is slidably connected to the rotating handle 53, a swing rod 55 is welded to the bottom of the pull ring 47, the swing rod 55 is slidably connected to the transverse groove of the swing plate 54 away from the rotating handle 53, and the swing rod 55 drives the pull ring 47 to swing.

[0027] When testing the abrasion resistance of the ultra-high molecular weight polyethylene fiber rope 49, the tester first wraps the ultra-high molecular weight polyethylene fiber rope 49 around the friction surface of the friction plate 42 and ties both ends to the upper fixed ball table 43 and the lower fixed ball table 48. Then, the bidirectional motor 51 is started. The output shaft at the bottom of the bidirectional motor 51 drives the power shaft 52 and the rotating handle 53 to rotate forward together. The rotating handle 53 rotates forward and pushes the swing plate 54 to swing back and forth around the rotating bolt 531 along one of the transverse grooves of the swing plate 54. The swing plate 54 swings back and forth and pushes the pull ring 47 and the swing rod 55 to swing back and forth along the other transverse groove of the swing plate 54. The pull ring 47 swings back and forth and pulls the two sliding seats 45 to slide along the sliding grooves of the two fixed support plates 41. The pull ring 47 swings back and forth and pushes the two guide plates 44 to move back and forth within the two sliding seats 45. The pull ring 47 swings back and forth and drives the lower fixed ball table 48 and one end of the ultra-high molecular weight polyethylene fiber rope 49 to swing back and forth, passing through the upper fixed ball table 48. The platform 43, the lower fixed ball platform 48, and the friction plate 42 make the ultra-high molecular weight polyethylene fiber rope 49 arc-shaped, thus ensuring full contact between the ultra-high molecular weight polyethylene fiber rope 49 and the friction surface of the friction plate 42. By driving the ultra-high molecular weight polyethylene fiber rope 49 to swing back and forth against the friction surface of the friction plate 42, the friction scenario of the ultra-high molecular weight polyethylene fiber rope 49 in actual use is simulated, thereby testing the wear resistance of the ultra-high molecular weight polyethylene fiber rope 49. After the wear resistance test of the ultra-high molecular weight polyethylene fiber rope 49 is completed, the tester turns off the bidirectional motor 51. The output shaft at the bottom of the bidirectional motor 51 stops rotating and no longer drives the power shaft 52 and the rotating handle 53 to rotate forward. The pull ring 47, the lower fixed ball platform 48, and the ultra-high molecular weight polyethylene fiber rope 49 also stop swinging back and forth. The sliding seat 45 stops moving. Finally, the tester unties both ends of the ultra-high molecular weight polyethylene fiber rope 49 and removes the ultra-high molecular weight polyethylene fiber rope 49.

[0028] Example 2 is based on Example 1, such as... Figures 2-4 As shown, it also includes a rotating mechanism. The upper fixed ball table 43 is equipped with a rotating mechanism for rotating the ultra-high molecular weight polyethylene fiber rope 49. The rotating mechanism includes an inclined plate 61. An inclined plate 61 is welded to the middle of the fixed table 3. A drive shaft 62 is rotatably connected to the inclined plate 61. The inclined plate 61 is used to support the drive shaft 62. A universal coupling 63 is connected between the lower end of the drive shaft 62 and the output shaft of the bidirectional motor 51. The universal coupling 63 is also connected between the upper end of the drive shaft 62 and the upper fixed ball table 43. The universal coupling 63 is used for oblique angle transmission. A drive wheel 64 is fixedly connected to both the upper fixed ball table 43 and the lower fixed ball table 48. A drive rope 65 is wound between the two drive wheels 64. The drive rope 65 is interlaced with the two drive wheels 64.

[0029] The output shaft of the bidirectional motor 51 rotates forward, driving the lower universal coupling 63 to rotate forward. The lower universal coupling 63 drives the drive shaft 62 and the upper universal coupling 63 to rotate forward. The drive shaft 62 drives the upper fixed ball table 43 to rotate forward together through the upper universal coupling 63. The forward rotation of the upper fixed ball table 43 drives one of the drive wheels 64 to rotate forward. The forward rotation of one of the drive wheels 64 drives the lower fixed ball table 48 and another drive wheel 64 on the lower fixed ball table 48 to rotate in reverse through the drive rope 65. The drive rope 65 drives the upper fixed ball table 43 to rotate forward and the lower fixed ball table 48 to rotate in reverse, so that the entire ultra-high molecular weight polyethylene fiber rope 4 9. Rotate but do not tighten, so that the friction surface of the friction plate 42 can rub the entire ultra-high molecular weight polyethylene fiber rope 49 in multiple directions and angles, thereby comprehensively testing the friction of the ultra-high molecular weight polyethylene fiber rope 49 and making the wear resistance test of the ultra-high molecular weight polyethylene fiber rope 49 more accurate. After the ultra-high molecular weight polyethylene fiber rope 49 test is completed, the tester turns off the bidirectional motor 51. The output shaft of the bidirectional motor 51 stops rotating, and the universal coupling 63, the drive shaft 62 and the upper universal coupling 63 stop rotating. The upper fixed ball table 43 and the lower fixed ball table 48 also stop rotating.

[0030] Example 3: Based on Example 2, such as Figures 5-7 As shown, it also includes a tensioning mechanism, which is mounted on the two sliding seats 45. The tensioning mechanism is used to tension the ultra-high molecular weight polyethylene fiber rope 49. The tensioning mechanism includes a triangular rod 71, which is welded between the two sliding seats 45. A rotating shaft 72 is rotatably connected to the fixed platform 3. A half-tooth gear 73 is fixedly connected to the lower part of the rotating shaft 72. The half-tooth gear 73 has two slots and a protrusion. The rotating bolt 531 is fixedly... A sector gear 74 is fixedly connected to the fixed platform 3, and the sector gear 74 meshes with the half-tooth gear 73. A locking rod 75 is slidably connected to the fixed platform 3, and a compression spring 76 is connected between the locking rod 75 and the fixed platform 3. A sector disk 77 is welded to the upper part of the rotating shaft 72, and a torsion spring 78 is connected between the sector disk 77 and the fixed platform 3. The torsion spring 78 is used for resetting. The sector disk 77 contacts the triangular rod 71 and is used to push the triangular rod 71.

[0031] It also includes a limiting cover 8, which is fixedly connected to the friction surface of the friction plate 42.

[0032] Initially, the sector gear 74 compresses the compression spring 76, and the protrusion of the half-gear 73 limits the torsion spring 78, causing the torsion spring 78 to twist. The rotating bolt 531 and the swing plate 54 reciprocate, driving the sector gear 74 to rotate reciprocally. After the sector gear 74 rotates, driving the rotating shaft 72, the half-gear 73, and the sector disk 77 to rotate, the torsion spring 78 is twisted, and the half-gear 73 no longer compresses the compression spring 76. The sector gear 74 continues to rotate and disengages from the half-gear 73. The protrusion on the half-gear 73 disengages from the locking rod 75, and simultaneously, the locking rod 75, under the reset action of the compression spring 76, engages with one of the half-gears 73. In the slot, the half-tooth gear 73 stops rotating, while the rotating bolt 531 and the swing plate 54 continue to drive the sector wheel 74 to swing back and forth. The sector disk 77 rotates and squeezes the triangular rod 71 to move towards the fixed platform 3. The triangular rod 71 pulls the two sliding seats 45 to move along the sliding grooves of the two fixed support plates 41. The two sliding seats 45 drive the two moving rods 46 and the pull ring 47 to move together. The pull ring 47 pulls the lower fixed ball platform 48 to move the lower end of the ultra-high molecular weight polyethylene fiber rope 49 together. The ultra-high molecular weight polyethylene fiber rope 49 is tightened. Because the slot of the half-tooth gear 73 is locked by the locking rod 75, the sector disk 77 remains aligned with the ultra-high molecular weight polyethylene fiber rope 3. The tension of the polyethylene fiber rope 49 is measured by pulling one end of the ultra-high molecular weight polyethylene fiber rope 49, causing it to become taut. This taut state of the ultra-high molecular weight polyethylene fiber rope 49 is then stimulated by the upper fixed ball table 43 and the lower fixed ball table 48, which rotate the ultra-high molecular weight polyethylene fiber rope 49. The pull ring 47 then causes the ultra-high molecular weight polyethylene fiber rope 49 to swing back and forth, thus comprehensively improving the friction test of the ultra-high molecular weight polyethylene fiber rope 49 and making the test results more obvious. Simultaneously, the limiting cover 8 can limit the movement of the ultra-high molecular weight polyethylene fiber rope 49, ensuring that the ultra-high molecular weight polyethylene fiber rope 49 remains within its taut state. The high molecular weight polyethylene fiber rope 49 can stably perform friction tests with the friction surface of the friction plate 42, thereby making the wear resistance test of the ultra-high molecular weight polyethylene fiber rope 49 more accurate. After the ultra-high molecular weight polyethylene fiber rope 49 test is completed, the tester turns off the bidirectional motor 51 and pulls the clamping rod 75 to reset. The compression spring 76 is compressed, and the clamping rod 75 no longer jams the slot of the half gear 73. The half gear 73 and the sector disk 77 are reset under the action of the torsion spring 78. The sector disk 77 no longer squeezes the triangular rod 71, and the protrusion of the half gear 73 is again limited by the clamping rod 75. Finally, the ultra-high molecular weight polyethylene fiber rope 49 can be easily removed after testing.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
