A rigging rope tensile fatigue testing device

Abstract

This utility model discloses a rigging rope tensile fatigue testing device, relating to the field of rigging tensile fatigue testing technology. It includes a testing platform with a mounting base fixedly installed on its top. The advantages of this utility model are: by fixing the rigging rope to the outside of a fixed rod and a roller, the turntable can be driven to rotate by turning on a reduction motor. The turntable, through a pivot pin, drives a connecting rod to move, which in turn pulls a T-shaped slide bar, causing the rack to move. The rack then meshes with a gear, driving the roller to rotate, allowing the rigging rope to be repeatedly stretched and then relaxed, thus performing repeated tensile tests. Turning on the reduction motor drives the turntable to rotate, which in turn drives the T-shaped slide bar to move, causing the roller to rotate and stretch the rigging rope taut. Then, turning off the reduction motor allows the self-locking property to fix the roller, keeping the rigging rope in a stretched state for further tension testing. One device can perform different tests, making it more functional.

Description

Technical Field

[0001] This utility model relates to the field of rigging tensile fatigue testing technology, specifically a rigging rope tensile fatigue testing device. Background Technology

[0002] Rigging refers to equipment used with ropes and cables, such as hooks, tensioners, clamps, swivels, and shackles. While some classifications include ropes and cables, rigging is also sometimes used. Rigging is mainly divided into two categories: metal rigging and synthetic fiber rigging.

[0003] Currently, all existing rigging ropes require repeated tensile testing and long-term tension testing after production to assess their strength. However, existing tensile fatigue testing equipment has limited functionality; different devices can only be used for repeated tensile testing or long-term tension testing for different tests, and cannot be used for different tensile fatigue tests simultaneously. Therefore, we propose a rigging rope tensile fatigue testing device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a rigging rope tensile fatigue testing device, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rigging rope tensile fatigue testing device, comprising a testing platform, a mounting base fixedly installed on the top of the testing platform, two guide rods fixedly installed on one side of the mounting base, a rack slidably installed on the outer side of the guide rods, a rotating frame fixedly installed on the top of the testing platform, a winding roller rotatably installed in the middle of the rotating frame, rotating shafts fixedly installed on both sides of the winding roller, gears fixedly installed on the outer side of the rotating shafts, the gears meshing with the racks, a T-shaped sliding rod slidably installed in the middle of the mounting base, a connecting rod rotatably installed at one end of the T-shaped sliding rod, a reduction motor fixedly installed on the top of the testing platform, a turntable fixedly installed at the output end of the reduction motor, a pivot pin fixedly installed on one side of the turntable, and the connecting rod movably connected to the pivot pin.

[0006] Furthermore, a binding rod is fixedly installed on the outer side of the roller, and two fixing frames are fixedly installed on one side of the top of the test platform, with a fixing rod fixedly installed in the middle of the two fixing frames.

[0007] Furthermore, a counter is provided on one side of the mounting base, a counting button is provided on one side of the counter, and a touch plate is fixedly installed on one side of the T-shaped slide bar, the touch plate cooperating with the counting button.

[0008] Furthermore, a timer is provided on the top of the mounting base.

[0009] Furthermore, an L-shaped protective plate is fixedly installed on the top of the test bench and on one side of the roller.

[0010] Furthermore, the T-shaped slide bar is fixedly connected to one side of the two racks.

[0011] Furthermore, two vertical plates are fixedly installed on the top of the test platform, and the other ends of the two guide rods are fixedly connected to the two vertical plates respectively.

[0012] Furthermore, a rigging rope is wound around the outside of the roller, with one end of the rigging rope sleeved on the outside of the binding rod and the other end of the rigging rope sleeved on the outside of the fixing rod.

[0013] This utility model provides a rigging rope tensile fatigue testing device, which has the following beneficial effects:

[0014] This rigging rope tensile fatigue testing equipment, through the setup of a mounting base, guide rod, rack, roller, rotating shaft, gear, T-shaped slide bar, connecting rod, geared motor, turntable, and pivot pin, allows for tensile fatigue testing of rigging ropes. After fixing the rigging rope to the outside of the fixed rod and the roller, turning on the geared motor drives the turntable to rotate. The turntable, through the pivot pin, moves the connecting rod, which in turn pulls the T-shaped slide bar, causing the rack to move. This, in turn, allows the rack to mesh with the gear, driving the roller to rotate. This allows for repeated stretching and releasing of the rigging rope through the roller, enabling repeated tensile testing. Simultaneously, turning on the geared motor drives the turntable to rotate, causing the T-shaped slide bar to move and the roller to stretch the rigging rope taut. Afterwards, turning off the geared motor allows the self-locking mechanism to fix the roller, keeping the rigging rope in a stretched state for further tension testing. One device can perform different tests, making it more versatile. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a rigging rope tensile fatigue testing device, including a test platform 1, a mounting base 2 fixedly installed on the top of the test platform 1, two guide rods 3 fixedly installed on one side of the mounting base 2, a rack 4 slidably installed on the outer side of the guide rods 3, a rotating frame 5 fixedly installed on the top of the test platform 1, a winding roller 6 rotatably installed in the middle of the rotating frame 5, a rotating shaft 7 fixedly installed on both sides of the winding roller 6, a gear 8 fixedly installed on the outer side of the rotating shaft 7, the gear 8 meshing with the rack 4, a T-shaped sliding rod 9 slidably installed in the middle of the mounting base 2, a connecting rod 10 rotatably installed at one end of the T-shaped sliding rod 9, a reduction motor 11 fixedly installed on the top of the test platform 1, a turntable 12 fixedly installed at the output end of the reduction motor 11, a pivot pin 13 fixedly installed on one side of the turntable 12, and the connecting rod 10 movably connected to the pivot pin 13; wherein the reduction motor 11 has a reduction function and self-locking property, and a controller is provided on one side of the test platform 1. The controller can control the start and stop of the geared motor 11. When a tensile fatigue test is performed on the rigging rope, the controller turns on the geared motor 11, which drives the turntable 12 and the pivot pin 13 to rotate. The pivot pin 13 drives the connecting rod 10 to move along the trajectory of the pivot pin 13. The connecting rod 10 pulls the T-shaped slide bar 9, which drives the two racks 4 to move back and forth on the guide rod 3. When the racks 4 move, they mesh with the gear 8, which drives the roller 6 to rotate back and forth through the rotating shaft 7. When the roller 6 rotates, it can repeatedly wind and unwind the rigging rope, thus repeatedly stretching the rigging rope until it breaks, which can test its frequent tensile life. Similarly, when a long-term tension tensile fatigue test is required on the rigging rope, the controller turns on the geared motor 11 to drive the turntable 12 to rotate. The pivot pin 13 drives the connecting rod 10 to the rightmost side of the turntable 12, which can tighten the rigging rope. This can test the long-term tensile life of the rigging rope.

[0023] A binding rod 14 is fixedly installed on the outer side of the roller 6, and two fixing frames 15 are fixedly installed on one side of the top of the test platform 1. A fixing rod 16 is fixedly installed in the middle of the two fixing frames 15. One end of the rigging rope can be fixed by the binding rod 14, and the other end of the rigging rope can be fixed by the fixing rod 16. After fixing both ends of the rigging rope to the outer side of the roller 6 and the fixing rod 16 respectively, a tensile fatigue test can be performed on it.

[0024] A counter 17 is provided on one side of the mounting base 2, and a counting button 18 is provided on one side of the counter 17. A touch plate 19 is fixedly installed on one side of the T-shaped slide bar 9, and the touch plate 19 cooperates with the counting button 18. With the setting of the touch plate 19, when the T-shaped slide bar 9 is pulled and moves repeatedly in the mounting base 2, the touch plate 19 can repeatedly contact the counting button 18, thereby realizing the counting of the number of times the rigging rope is stretched.

[0025] The top of the mounting base 2 is equipped with a timer 20; by setting the timer 20, when a long-term tension test is performed on the rigging rope, the timer 20 can be used to time the test time, thereby testing the tensile life of the rigging rope.

[0026] An L-shaped protective plate 21 is fixedly installed on the top of the test platform 1 and on one side of the roller 6. The L-shaped protective plate 21 can prevent the rigging rope from breaking during the stretching process, thus avoiding the situation where the rigging rope breaks and flies away, injuring the test personnel.

[0027] The T-shaped slide bar 9 is fixedly connected to one side of the two racks 4; by connecting the T-shaped slide bar 9 to the two racks 4, the two racks 4 can be moved simultaneously by the T-shaped slide bar 9.

[0028] Two vertical plates are fixedly installed on the top of the test bench 1, and the other ends of the two guide rods 3 are fixedly connected to the two vertical plates respectively; the vertical plates can improve the stability of the guide rods 3 installation.

[0029] A rigging rope is wound around the outside of the roller 6. One end of the rigging rope is fitted onto the outside of the binding rod 14, and the other end of the rigging rope is fitted onto the outside of the fixing rod 16. Depending on the length of the rigging rope, it can be wound around the outside of the roller 6 multiple times until the roller 6 is driven to rotate by the reduction motor 11, which ensures that the rigging rope is stretched and taut. The binding rod 14 and the fixing rod 16 facilitate the fixing of both ends of the rigging rope.

[0030] In summary, when using this rigging rope tensile fatigue testing equipment, firstly, one end of the rigging rope is fixed to the outside of the binding rod 14. Then, according to the length of the rigging rope, it is wound around the outside of the roller 6, and the other end is fixed to the fixing rod 16. Then, the test can begin. During the test, the reduction motor 11 is turned on by the controller. The reduction motor 11 drives the turntable 12 and the pivot pin 13 to rotate. The pivot pin 13 drives the connecting rod 10 to move along the trajectory of the pivot pin 13. In turn, the connecting rod 10 pulls the T-shaped slide bar 9, which drives the two racks 4 to move back and forth on the guide rod 3. When the racks 4 move, they mesh with the gear 8, which drives the roller 6 to rotate back and forth through the rotating shaft 7. When the roller 6 rotates, it can repeatedly wind and unwind the rigging rope, thereby repeatedly stretching the rigging rope until it reaches its maximum tension. The rigging rope's lifespan can be tested by observing its breakage. When the T-shaped slide bar 9 reciprocates within the mounting base 2, the touch plate 19 presses the counting button 18, causing the counter 17 to count. Once the rigging rope breaks, the count on the counter 17 is checked to determine the rigging rope's lifespan. Similarly, when a long-term tension fatigue test is required, the controller activates the reduction motor 11 to drive the turntable 12 to rotate. The connecting rod 10 is then moved to the far right of the turntable 12 via the pivot pin 13, thus tauting the rigging rope. The timer 20 is then activated to keep track until the taut rigging rope breaks due to fatigue. The time on the timer 20 is then observed to determine the rigging rope's long-term tensile lifespan.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
