Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire rope testing technology, specifically a wire rope intermediate tension testing device. Background Technology
[0002] Steel wire rope is a flexible circular cross-section component made of multiple strands of metal wire twisted according to specific rules. It combines high strength, high toughness, and fatigue resistance, and can transmit tensile force or bear loads under complex working conditions. It is widely used in hoisting, transportation, construction, marine engineering, and other fields. Its core advantage lies in integrating the strength of individual steel wires into overall load-bearing capacity through distributed force and coordinated twisting, while maintaining flexibility to adapt to the installation and use requirements of different scenarios.
[0003] A wire rope intermediate tension detection device, disclosed in CN222800226U, uses a closed plate to limit the wire rope by inserting a plate and a second guide groove. This allows for quick installation when the middle of the wire rope needs to be tested. It also drives the slide rail and the slide groove to slide. When the slide rail slides out of the slide groove, the push wheel and guide wheel can be replaced, which is convenient for quickly replacing the push wheel and guide wheel when the wire rope specifications are different.
[0004] The wire rope intermediate tension detection device closes the sealing plate so that the insert plate and the second guide groove limit the wire rope, which facilitates quick installation when the middle of the wire rope needs to be tested. However, the device does not have a structure to press and fix the wire rope, which makes the wire rope easy to move during the testing process and affects the testing effect. Therefore, it needs to be improved. Utility Model Content

[0028] This utility model provides the following technical solution:
[0029] Example 1
[0030] Please see Figure 1-4 This utility model provides a technical solution: a wire rope intermediate tension detection device, including a detection platform 1, a vertical plate 2 fixedly connected to the top back end of the detection platform 1, a pressing mechanism 3 provided at the back end of the vertical plate 2, a detection mechanism 4 provided on the front of the vertical plate 2, and a wire rope body 5 provided inside the pressing mechanism 3.
[0031] The pressing mechanism 3 includes a protective frame 33, which is fixedly connected to the middle of the back end of the vertical plate 2. A drive motor 32 is fixedly connected to the top of the protective frame 33. A threaded rod 39 is fixedly connected to the bottom of the drive motor 32. The threaded rod 39 is rotatably connected to the inner side of the fixed frame 36. A threaded plate 38 is threadedly connected to the outer side of the threaded rod 39. Connecting plates 34 are fixedly connected to the left and right sides of the threaded plate 38. A linkage plate 35 is fixedly connected to the front of the connecting plate 34. A fixed frame 36 is fixedly connected to the front of the linkage plate 35. A pressing roller 37 is fixedly connected to the inner side of the fixed frame 36. A U-shaped plate 31 is fixedly connected to the front of the vertical plate 2.
[0032] Furthermore, the inner side of the protective frame 33 is provided with a groove corresponding to the movement trajectory of the threaded plate 38, and the threaded plate 38 is slidably connected inside the groove. The groove can support the threaded plate 38, making the threaded plate 38 more stable during the lifting and lowering process.
[0033] Furthermore, a fixing groove corresponding to the movement trajectory of the linkage plate 35 is provided on the inner side of the vertical plate 2, and the linkage plate 35 is slidably connected to the inside of the fixing groove. Through the fixing groove, the linkage plate 35 can slide on the inner side of the vertical plate 2, so that when the linkage plate 35 moves, it can drive the fixing frame 36 to move up and down.
[0034] Furthermore, the wire rope body 5 is located inside the U-shaped plate 31, and the outer periphery of the wire rope body 5 is in close contact with the inner side of the U-shaped plate 31. The U-shaped plate 31 can support the wire rope body 5.
[0035] Furthermore, the pressing roller 37 is set on the top of the U-shaped plate 31, and the bottom of the pressing roller 37 is in contact with the inside of the U-shaped plate 31. The pressing roller 37 can press and fix the wire rope body 5 on the top of the U-shaped plate 31, making the wire rope body 5 more stable during the tension detection process.
[0036] Example 2
[0037] Please see Figure 1-4 Furthermore, based on Embodiment 1, the detection mechanism 4 further includes a fixed plate 47, which is fixedly connected to the bottom front of the vertical plate 2. A hydraulic cylinder 45 is fixedly connected to the bottom of the fixed plate 47. A load-bearing plate 43 is fixedly connected to the top of the hydraulic cylinder 45. A sliding rod 46 is fixedly connected to the bottom of the load-bearing plate 43. A telescopic rod 42 is fixedly connected to the outer side of the top of the load-bearing plate 43. A support plate 49 is fixedly connected to the top of the telescopic rod 42. A push roller 41 is fixedly connected to the top of the support plate 49. A detector 44 is fixedly connected to the middle of the top of the load-bearing plate 43. The detector 44 is fixedly connected to the bottom of the support plate 49. A spring 48 is sleeved around the telescopic rod 42.
[0038] Furthermore, the top of the spring 48 is fixedly connected to the bottom of the support plate 49, and the bottom of the spring 48 is fixedly connected to the top of the load-bearing plate 43. When the push roller 41 drives the support plate 49 to move downward, the support plate 49 can squeeze the telescopic rod 42 and the spring 48. When the push roller 41 is not blocked by the wire rope body 5, the elastic force of the spring 48 enables the push roller 41 to return to its original position.
[0039] Furthermore, there are four telescopic rods 42, which are fixedly connected to the top of the load-bearing plate 43. The telescopic rods 42 can provide support for the support plate 49.
[0040] Furthermore, there are two slide rods 46, which are fixedly connected to the left and right sides of the bottom of the load-bearing plate 43, and are slidably connected to the inner side of the fixed plate 47. The slide rods 46 can support the load-bearing plate 43, making the load-bearing plate 43 more stable during the lifting and lowering process.
[0041] Furthermore, the push roller 41 is disposed at the bottom of the wire rope body 5, and the top of the push roller 41 is in contact with the middle of the bottom of the wire rope body 5. The push roller 41 can push the wire rope body 5 to move upward and detect the tension of the wire rope body 5.
[0042] In actual operation, when this device is used, during the testing process, the wire rope body 5 is first placed inside the U-shaped plate 31, so that its outer periphery is in contact with the inner side of the U-shaped plate 31. The U-shaped plate 31 provides initial support for the wire rope body 5. The operator turns on the drive motor 32 switch, so that the drive motor 32 drives the threaded rod 39 at the bottom to rotate inside the fixed frame 36. Under the rotation of the threaded rod 39, the threaded plate 38 rises and falls steadily along the slide. The rise and fall of the threaded plate 38 drives the linkage plate 35 to move synchronously through the connecting plates 34 on the left and right sides. The linkage plate 35 drives the fixed frame 36 on the front and the pressing roller 37 on the inner side to rise and fall. When the pressing roller 37 descends to contact and fit with the wire rope body 5 at the top of the U-shaped plate 31, the wire rope body 5 is pressed and fixed, ensuring its position is stable during subsequent testing and avoiding shaking.
[0043] When the hydraulic cylinder 45 switch is turned on, the hydraulic cylinder 45 drives the top support plate 43 to rise and fall. When the support plate 43 rises, it drives the support plate 49 and the top push roller 41 to rise synchronously until the top of the push roller 41 contacts the middle of the bottom of the wire rope body 5. The push roller 41 continues to push the wire rope body 5 upward. The wire rope body 5 is subjected to an upward thrust, and its own tension reacts to the push roller 41. The push roller 41 transmits the force to the support plate 49. The detector 44 at the bottom middle of the support plate 49 is fixedly connected to the support plate 49 and can directly sense the force on the support plate 49. At the same time, under the action of the force, the support plate 49 will squeeze the telescopic rod 42 and the outer spring 48 downward. The spring 48 is compressed and generates elastic force, which plays a buffering role and reduces the impact of instantaneous impact on the detection. The detector 44 converts the sensed force signal into tension data, thereby completing the detection of the tension in the middle of the wire rope body 5. The detector 44 model is FP5000.
