[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] See Figure 1 An embodiment of the present application provides a creep testing device, including a frame 1, a loading beam 2, a first clamp 3, a second clamp 4 and a driving component 5. The loading beam 2 is slidably arranged along the height direction of the frame 1; the first clamp 3 is connected to the loading beam 2, and the first clamp 3 is used to clamp one end of the rope; the second clamp 4 is connected to the frame 1, and the second clamp 4 is used to clamp the other end of the rope; the driving component 5 is installed in the frame 1, and the driving component 5 is used to drive the loading beam 2 to move.

[0028] In actual application, the first clamp 3 and the second clamp 4 respectively clamp the two ends of the rope, and the first clamp 3 is connected to the loading beam 2. When the driving component 5 drives the loading beam 2 to slide along the height direction of the frame 1, the loading beam 2 drives the first clamp 3 to move. The first clamp 3 applies tension to the rope, and the rope deforms under the action of force, which is a creep process. By testing the deformation ability of the rope under different tensions, the creep performance of the rope can be studied, thereby ensuring the safety and life of the equipment.

[0029] Specifically, the driving component 5 includes a driving motor 51, a driving gear 52, a driven gear 53 and a rotating screw 54. The rotating screw 54 is rotatably connected to the frame 1 and is threadedly connected to the loading beam 2. The driving gear 52 is connected to the driving end of the driving motor 51, and the driven gear 53 is connected to the rotating screw 54. The driving gear 52 and the driven gear 53 are transmission-connected, and the transmission ratio of the driving gear 52 and the driven gear 53 is greater than 1.

[0030] It should be noted that the height direction of the frame 1 refers to the extending direction of the rope; the transmission ratio here refers to the ratio of the number of teeth of the driven gear 53 to the number of teeth of the driving gear 52.

[0031] In order to improve the test accuracy of the experiment, the present application provides a driving gear 52 and a driven gear 53 with a transmission connection. The driving gear 52 is connected to the output end of the driving motor 51, and the driven gear 53 is connected to the rotating screw 54. When the driving motor 51 is started, the driving motor 51 drives the driving gear 52 to rotate, and the driving gear 52 drives the driven gear 53 to rotate, and further drives the rotating screw 54 to rotate. The loading beam 2 is threadedly connected to the rotating screw 54 and is limited by the frame 1. Therefore, the loading beam 2 can move along the height direction of the frame 1 under the rotation of the rotating screw 54, thereby driving the first clamp 3 to move, thereby completing the stretching effect on the rope. Compared with the prior art, the transmission ratio of the driving gear 52 and the driven gear 53 of the present application is greater than 1, and the rotation speed of the driven gear 53 is less than that of the driving gear 52, thereby improving the rotation accuracy of the rotating screw 54, so that the rotating screw 54 can rotate with a smaller amplitude, and the stroke of each movement of the first clamp 3 is smaller. This arrangement can more accurately control the tension applied to the rope, thereby improving the accuracy of the rope creep test.

[0032] See Figure 2 and Figure 3 The driving component 5 also includes a transmission assembly 55, which is respectively connected to the driving gear 52 and the driven gear 53; wherein the transmission ratio of the transmission assembly 55 to the driving gear 52 is greater than 1, and the transmission ratio of the transmission assembly 55 to the driven gear 53 is greater than 1.

[0033] In actual application, the transmission component 55 is respectively connected to the driving gear 52 and the driven gear 53, and the transmission ratio of the transmission component 55 to the driving gear 52 is greater than 1, that is, the rotational speed of the transmission component 55 is less than that of the driving gear 52, and the transmission ratio of the transmission component 55 to the driven gear 53 is also greater than 1, that is, the rotational speed of the driven gear 53 is less than that of the transmission component 55. By setting traditional components, a two-stage reduction in speed of the driving gear 52 is achieved, and the rotational speed of the driven gear 53 is further reduced, thereby further improving the test accuracy of the test.

[0034] It can be understood that the transmission ratio here refers to the ratio of the number of teeth of the driven gear 53 to the number of teeth of the driving gear 52. For example, between the driving gear 52 and the transmission assembly 55, the transmission assembly 55 is the driven gear 53; between the transmission assembly 55 and the driven gear 53, the transmission assembly 55 is the driving gear 52.

[0035] See again Figure 3 The transmission assembly 55 includes a rotating shaft 553, a first gear 551 and a second gear 552. The rotating shaft 553 is rotatably connected to the frame 1. The first gear 551 and the second gear 552 are both connected to the rotating shaft 553, and the first gear 551 and the second gear 552 rotate coaxially. The first gear 551 is connected to the driving gear 52, and the second gear 552 is connected to the driven gear 53; wherein, the transmission ratio of the first gear 551 to the driving gear 52 is greater than 1, and the transmission ratio of the second gear 552 to the driven gear 53 is greater than 1.

[0036] In actual applications, the coaxial rotation of the first gear 551 and the second gear 552 may include the same angular velocity of the two, that is, the same rotational speed. Therefore, when the driving gear 52 drives the first gear 551 to rotate, the rotational speed of the first gear 551 is lower than that of the driving gear 52, and the second gear 552 has the same rotational speed as the first gear 551, and the rotational speed of the second gear 552 is also lower than that of the driving gear 52, thereby achieving a first-level speed reduction of the driving gear 52; when the second gear 552 drives the driven gear 53 to rotate, the rotational speed of the driven gear 53 is lower than that of the second gear 552, thereby achieving a second-level speed reduction of the driving gear 52, thereby improving the test accuracy.

[0037] It is understood that multiple rotating screws 54 are typically symmetrically disposed on both sides of the loading beam 2. For example, two rotating screws 54 may be provided, and the loading beam 2 is threadedly connected to the two rotating screws 54. This allows the loading beam 2 to be evenly stressed and move more smoothly and stably. Therefore, when there are multiple rotating screws 54, there may also be multiple driven gears 53 and second gears 552, which is not limited in this application.

[0038] See again Figure 3The driving component 5 includes a synchronous belt 56, the first gear 551 is connected to the driving gear 52 through the synchronous belt 56, and the second gear 552 is connected to the driven gear 53 through the synchronous belt 56; the use of the synchronous belt 56 connection method can ensure that the transmission between the gears is more stable, realize non-slip transmission, and is simple to install, does not require lubrication, and saves space.

[0039] See again Figure 3 The frame 1 is provided with a first mounting slot 11 and a second mounting slot 12. The driving gear 52, the driven gear 53 and the transmission assembly 55 are all arranged in the first mounting slot 11. One end of the rotating screw 54 extends into the first mounting slot 11 for connecting with the driven gear 53. The driving motor 51 is installed in the second mounting slot 12. The output end of the driving motor 51 extends into the first mounting slot 11 for connecting with the driving gear 52.

[0040] In practical applications, the first installation slot 11 and the second installation slot 12 can separate the drive motor 51 and the gear assembly so that they can be installed independently, thereby improving assembly efficiency, avoiding mutual interference during installation, and facilitating maintenance.

[0041] See again Figure 3 The driving component 5 further includes a reducer 57, the output end of the driving motor 51 is connected to the reducer 57, and the output end of the reducer 57 is connected to the driving gear 52. The reducer 57 can be a planetary reducer.

[0042] It should be noted that the reducer 57 is a device that can reduce the rotational speed of the drive motor 51, and usually includes an input shaft and an output shaft. The input shaft is connected to the output end of the drive motor 51, and the output shaft is connected to the driving gear 52, thereby achieving a deceleration effect on the drive motor 51, reducing the rotational speed of the drive motor 51 output to the driving gear 52, and improving the test accuracy.

[0043] See Figure 4 and Figure 5 The creep testing device includes a temperature box 6, which is slidably connected to the frame 1, a first clamp 3 is used to connect one end of the rope to extend into the temperature box 6, and a second clamp 4 is used to connect one end of the rope to extend into the temperature box 6.

[0044] In practice, the temperature chamber 6 is used to control temperature conditions during the test, as temperature is a key factor influencing material creep. Furthermore, the temperature chamber 6 can simulate actual operating environments. For example, by conducting creep tests at specific temperatures for ropes operating in high or low temperatures, the rope's performance in these environments can be better simulated. Furthermore, the chamber eliminates the effects of temperature fluctuations, providing a stable temperature environment and helping to mitigate the influence of external factors on test results.

[0045] It is understandable that the present application may also provide a temperature sensor and a temperature control meter for detecting and displaying the real-time temperature of the temperature box 6 so that the operator can adjust the temperature of the temperature box 6 .

[0046] See again Figure 4 The creep testing device includes an extension frame 7, which is connected to the frame body 1 and extends in a direction away from the frame body 1. A roller 10 is provided at the bottom of the temperature box 6. The roller 10 is connected to the extension frame 7 and can move along the extension direction of the extension frame 7.

[0047] This application provides an extension rack 7, and a roller 10 is provided at the bottom of the temperature box 6. The temperature box 6 is placed on the extension rack 7. The operator only needs to use a small force to push the temperature box 6 to the specified position to facilitate the assembly and disassembly of the temperature box 6.

[0048] See Figure 5 The creep test apparatus includes a sensor 8 connected to the loading beam 2 and the first clamp 3. Sensor 8 is used to detect the tension applied to the first clamp 3. In practice, when the first clamp 3 moves to stretch the rope, the rope exerts a tension on the first clamp 3. This tension is transmitted to sensor 8. The data measured by sensor 8 is used to determine the rope's current force, ensuring that the rope can be tested under constant tension.

[0049] See again Figure 5 The creep test apparatus includes an operating screen 9 electrically connected to the drive unit 5 for controlling the drive unit 5. The operating screen 9 is used by an operator to implement human-computer interaction, allowing the operator to input commands to start or stop the drive unit 5. The operating screen 9 is also electrically connected to the temperature chamber 6, allowing the operator to quickly and easily control the start and stop of the drive unit 5 and the temperature of the temperature chamber 6.

[0050] Different from the prior art, the embodiment of the present application provides a creep testing device, comprising a frame 1, a loading beam 2, a first clamp 3, a second clamp 4 and a driving component 5. The loading beam 2 is slidably arranged along the height direction of the frame 1; the first clamp 3 is connected to the loading beam 2, and the first clamp 3 is used to clamp one end of the rope; the second clamp 4 is connected to the frame 1, and the second clamp 4 is used to clamp the other end of the rope; the driving component 5 is installed in the frame 1, and the driving component 5 is used to drive the loading beam 2 to move. The driving component 5 includes a driving motor 51, a driving gear 52, a driven gear 53 and a rotating screw 54. The rotating screw 54 is rotatably connected to the frame 1 and is threadedly connected to the loading beam 2. The driving gear 52 is connected to the driving end of the driving motor 51, and the driven gear 53 is connected to the rotating screw 54. The driving gear 52 is transmission-connected to the driven gear 53, and the transmission ratio of the driving gear 52 to the driven gear 53 is greater than 1. Compared with the prior art, the transmission ratio of the driving gear 52 and the driven gear 53 of the present application is greater than 1, and the rotation speed of the driven gear 53 is less than that of the driving gear 52, thereby improving the rotation accuracy of the rotating screw 54, so that the rotating screw 54 can rotate with a smaller amplitude, and the stroke of each movement of the first clamp 3 is smaller. This arrangement can more accurately control the tension applied to the rope, thereby improving the accuracy of the rope creep test.

[0051] The above is only a specific implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
