Description

Technical Field

[0001] This invention belongs to the field of testing equipment technology, specifically relating to a novel high-toughness yarn profile strength testing device. Background Technology

[0002] Traditional steel fiber profile strength testing relies on single tensile or bending tests, which are difficult to fully simulate the complex stress scenarios of profiles in actual working conditions. In particular, for steel fiber profiles reinforced with high-toughness yarns, the collaborative stress characteristics between the internal yarns and steel fibers cannot be accurately captured and analyzed.

[0003] The announcement number CN116148068B discloses a high-toughness steel fiber profile strength testing device. By symmetrically installing two semi-cylindrical half-molds on the top of the platform, a concrete column can be wrapped around the outside of the steel fiber to be tested according to the actual testing needs. With the clamping of two electric grippers b, the device can achieve real-time measurement and measure the strength and toughness of the steel fiber under actual use environment.

[0004] The aforementioned application document utilizes electric gripper B and electric telescopic rod to achieve automatic opening and closing of the semi-mold and clamping of both ends of the steel fiber. However, it relies on the electric gripper to directly pull the profile. When the steel fiber covered by concrete suddenly breaks, the instantaneous impact force will be directly transmitted to its electric push rod or motor, which can easily lead to damage to the drive mechanism.

The mounting bracket has a sliding groove A on its inner side. A lifting plate is slidably connected inside the sliding groove. A spring B is fixedly connected to the top of the inner wall of the sliding groove A and the upper end of the lifting plate. A hydraulic cylinder is fixedly connected to the top of the inner side of the mounting bracket. A tension sensor is fixedly connected to the output end of the hydraulic cylinder. A pull plate is fitted to the bottom of the tension sensor. The pull plate has two inclined grooves. A sliding shaft A is slidably connected to the inner wall of the inclined groove.

A sliding plate is slidably connected to the inner wall of the rectangular box. A clamping plate is fixedly connected to the bottom of the sliding plate. The bottom of the clamping plate slides through the rectangular box.

[0007] Preferably, the lifting plate has a through groove in the middle, and the pull plate moves through the through groove.

[0008] Preferably, the inner wall of the through groove is provided with a sliding groove B, and a slider A is slidably connected to the inner wall of the sliding groove B. The slider A is fixedly connected to the outer wall of the connecting rod.

[0009] Preferably, a spring A is fixedly connected to the inner wall of the rectangular box, and the bottom of the spring A is fixedly connected to the top of the slide plate.

[0010] Preferably, a fixed protective plate is fixedly connected to the upper end of the base, an L-shaped plate is fixedly connected to the front side of the mounting frame, a mounting groove is provided on one side of the L-shaped plate, a mounting shaft is rotatably connected to the inner wall of the mounting groove, the upper end of the mounting shaft rotatably passes through the L-shaped plate and is fixedly fitted with a gear, movable plates slide through both sides of the mounting frame, a linkage rod A is fixedly connected to the side of the connecting rod A, a connecting rod B is fixedly connected to the outer wall of the connecting rod and the movable plate, a toothed plate is fixedly connected to the other end of the connecting rod B, and a movable protective plate is fixedly fitted to the outer wall of the mounting shaft.

[0011] Preferably, the toothed plate is located on the side of the gear and meshes with it, and the end of the linkage rod A away from the connecting rod A slides through the moving plate.

[0012] Preferably, the base has an internal cavity, the inner wall of which has a track groove, a slide rod slidably connected to the inner wall of the track groove, a connecting plate fixedly fitted to the outer wall of the slide rod, a slider B fixedly connected to the other end of the connecting plate, a cleaning rod fixedly connected to the outer wall of the slide rod, a movable groove at the upper end of the base, a linkage rod B fixedly connected to the bottom of the mounting shaft, a movable rod fixedly connected to the bottom of the linkage rod B, a sliding shaft B rotatably connected to the end of the movable rod away from the linkage rod B, a slide rail fixedly connected to the bottom of the internal cavity, a rectangular frame slidably connected to the outer wall of the slide rail, a limit frame fixedly connected to one end of the rectangular frame, the slider B slidably connected to the inner wall of the limit frame, and the sliding shaft B slidably connected to the inside of the rectangular frame.

[0013] Preferably, the base has openings on both sides, a collection box is slidably connected inside the openings, and a handle is fixedly connected to the outside of the collection box.

[0014] Preferably, the middle and both sides of the track groove are horizontal grooves, and the horizontal grooves on both sides are connected to the horizontal groove in the middle through an inclined groove.

[0015] The advantages of this application are: (1) This application uses a hydraulic cylinder to drive the pull plate to rise, and uses a slant groove to drive the clamping plate to automatically clamp the top of the yarn. With the help of the bottom electric telescopic rod, the yarn ends are firmly fixed. Spring A plays a buffering role when the yarn breaks, avoiding direct damage to the hydraulic cylinder and tension sensor from the impact force, protecting the core components, ensuring uniform force distribution, reliable detection results, and extending the service life of the equipment.

[0016] (2) This application utilizes the internal movement of the connecting rod to drive the movable protective plate to flip to the front of the detection area through the linkage rod, toothed plate and gear transmission, forming a safety protection. When the yarn breaks and splashes, the protective plate can effectively block high-speed fragments and prevent the operator from being injured. After the detection is completed, the connecting rod resets and drives the protective plate to automatically retract, ensuring the safety of the detection process.

[0017] (3) This application utilizes the rotation of the mounting shaft to drive the slide bar to reciprocate along the track groove through the linkage rod, movable rod and rectangular frame transmission. When the slide bar moves to the inclined groove section, the cleaning rod automatically extends from the movable groove, sweeps across the base surface, and pushes the broken wires and debris generated by the detection into the collection box, realizing the automatic lifting and cleaning of the cleaning rod. The collection box is easy to pull out for cleaning, effectively keeping the equipment clean and reducing the burden of manual cleaning. Attached Figure Description

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0021] Example 1, as Figures 1-3 As shown, a novel high-toughness yarn profile strength testing device includes a base 1, an mounting frame 2 fixedly connected to the upper end of the base 1, an electric telescopic rod 3 fixedly connected to the inner side of the mounting frame 2, and a clamping plate 4 fixedly connected to the output end of the electric telescopic rod 3. The mounting bracket 2 has a sliding groove A51 on its inner side. A lifting plate 52 is slidably connected inside the sliding groove A51. A spring B53 is fixedly connected to the top of the inner wall of the sliding groove A51 and the upper end of the lifting plate 52. A hydraulic cylinder 54 is fixedly connected to the top of the inner side of the mounting bracket 2. A tension sensor 55 is fixedly connected to the output end of the hydraulic cylinder 54. A pull plate 56 is mounted on the bottom of the tension sensor 55. The pull plate 56 has two inclined grooves 57. A sliding shaft A58 is slidably connected to the inner wall of the inclined groove 57. A connecting rod A59 is fixedly sleeved on the outer wall of the sliding shaft A58. A rectangular box 510 is fixedly connected to the bottom of the connecting rod A59. A sliding plate 511 is slidably connected to the inner wall of the rectangular box 510. A clamping plate 512 is fixedly connected to the bottom of the sliding plate 511. The bottom of the clamping plate 512 slides through the rectangular box 510.

[0022] A through slot 514 is provided in the middle of the lifting plate 52. The pull plate 56 moves through the through slot 514. The through slot 514 provides sufficient space for the pull plate 56 to move up and down, avoids structural interference with the lifting plate 52, and ensures the smoothness of the hydraulic cylinder 54 driving the pull plate 56 to rise and fall.

[0023] The inner wall of the through groove 514 is provided with a sliding groove B515, and a slider A516 is slidably connected to the inner wall of the sliding groove B515. The slider A516 is fixedly connected to the outer wall of the connecting rod A59. The setting of the sliding groove B515 and the slider A516 can effectively constrain the movement trajectory of the connecting rod A59, avoid unnecessary shaking or deviation during the lifting and lowering of the pull plate 56, and ensure that the sliding shaft A58 can always slide smoothly along the inner wall of the inclined groove 57. This drives the two clamping plates 512 to complete the clamping or loosening action of the yarn profile symmetrically and synchronously, ensuring that the yarn is subjected to uniform force during the testing process and improving the accuracy of the strength test results.

[0024] A spring A513 is fixedly connected to the inner wall of the rectangular box 510. The bottom of the spring A513 is fixedly connected to the top of the slide plate 511. The spring A513 can prevent the force generated by the yarn profile from acting directly on key components such as the hydraulic cylinder 54 or the tension sensor 55 after the yarn profile breaks, thus playing a buffering and protective role.

[0025] When using the above equipment, first place the high-toughness yarn profile to be tested on the upper end of the base 1, so that the top of the high-toughness yarn profile is between the two clamping plates 512. Then start the electric telescopic rod 3 to drive the clamping plate 4 to move towards the middle, and then the clamping plate 4 clamps and fixes the bottom of the high-toughness yarn profile. At this time, hydraulic cylinder 54 is activated, pushing tension sensor 55 and pull plate 56 upward. When pull plate 56 moves upward, its inner inclined groove 57 will squeeze slide shaft A58. Then, under the constraint of slider A516 and sliding groove B515, connecting rod A59 will move inward, driving rectangular box 510 to move inward synchronously. The two clamping plates 512 will then move closer together and tightly fit against the top of the yarn profile. After the clamping plates 512 contact the two sides of the profile, pull plate 56 continues to rise, and slide shaft A... 58 will not continue to slide inside the inclined groove 57, but will instead drive the connecting rod A59 to move upward as a whole. At this time, the rectangular box 510 will rise with the connecting rod A59. Since the clamping plate 512 has clamped the top of the yarn profile, the slide plate 511 will slide downward inside the rectangular box 510 and stretch the spring A513. When the slide plate 511 descends to the lowest point, the rectangular box 510 will drive the slide plate 511 and the clamping plate 512 to rise, thereby pulling the yarn profile upward, so that its strength can be tested. The spring A513 is designed to prevent the force generated by the yarn profile from directly acting on key components such as the hydraulic cylinder 54 or the tension sensor 55 after the yarn profile breaks, thus playing a buffering and protective role and extending the service life of the core components of the equipment.

[0026] Example 2, as Figures 1-4 As shown, based on Embodiment 1, a fixed protective plate 61 is fixedly connected to the upper end of the base 1, an L-shaped plate 62 is fixedly connected to the front side of the mounting bracket 2, a mounting groove 63 is provided on one side of the L-shaped plate 62, a mounting shaft 64 is rotatably connected to the inner wall of the mounting groove 63, the upper end of the mounting shaft 64 rotatably passes through the L-shaped plate 62 and is fixedly fitted with a gear 65, movable plates 66 slide through both sides of the mounting bracket 2, a linkage rod A67 is fixedly connected to the side of the connecting rod A59, a connecting rod B68 is fixedly connected to the outer wall of the movable plate 66, a toothed plate 69 is fixedly connected to the other end of the connecting rod B68, and a movable protective plate 610 is fixedly fitted on the outer wall of the mounting shaft 64. The toothed plate 69 is located on the side of the gear 65 and meshes with it, and the end of the linkage rod A67 away from the connecting rod A59 slides through the movable plate 66.

[0027] When the connecting rod A59 moves inward, the linkage rod A67 simultaneously drives the moving plate 66 to slide smoothly along the guide rail. The moving plate 66 pushes the toothed plate 69 forward through the connecting rod B68. The toothed plate 69 precisely meshes with the gear 65, thereby driving the mounting shaft 64 to rotate clockwise. This rotation causes the movable protective plate 610 to quickly flip to the front of the equipment's detection area, forming a fully covered safety barrier. During the detection process, if the yarn profile breaks and splashes due to excessive stress, the movable protective plate 610 can effectively block high-speed fragments, prevent operator injury, and ensure a safe working environment. After the test is completed, the connecting rod A59 is reset under the action of external force, and the linkage rod A67 drives the moving plate 66 to move backward. During the backward movement, the toothed plate 69 drives the gear 65 in the opposite direction, causing the mounting shaft 64 to rotate counterclockwise, thereby smoothly rotating the movable protective plate 610 back to the initial position.

[0028] Example 3, as Figures 5-7As shown, based on Embodiment 1 or Embodiment 2, the base 1 has an internal cavity, the inner wall of which has a track groove 71, a slide rod 72 is slidably connected to the inner wall of the track groove 71, a connecting plate 73 is fixedly sleeved on the outer wall of the slide rod 72, a slider B74 is fixedly connected to the other end of the connecting plate 73, a cleaning rod 76 is fixedly connected to the outer wall of the slide rod 72, the upper end of the base 1 has a movable groove 77, the bottom of the mounting shaft 64 is fixedly connected to a linkage rod B78, the bottom of the linkage rod B78 is fixedly connected to a movable rod 79, the end of the movable rod 79 away from the linkage rod B78 is rotatably connected to a sliding shaft B710, the bottom of the internal cavity is fixedly connected to a slide rail 712, the outer wall of the slide rail 712 is slidably connected to a rectangular frame 711, one end of the rectangular frame 711 is fixedly connected to a limit frame 75, the slider B74 is slidably connected to the inner wall of the limit frame 75, and the sliding shaft B710 is slidably connected to the inside of the rectangular frame 711.

[0029] The base 1 has openings on both sides, and a collection box 713 is slidably connected inside the openings. A handle 714 is fixedly connected to the outside of the collection box 713. The collection box 713 and the handle 714 can effectively collect the detection waste and dust swept off when the cleaning rod 76 slides, preventing impurities from accumulating and clogging the track groove 71 or affecting the operation of other components. The design of the handle 714 makes it convenient for operators to quickly pull out the collection box 713 for cleaning and maintenance, improving the convenience of daily maintenance of the equipment, ensuring the long-term stable operation of the detection equipment, and further optimizing the practicality and operating experience of the equipment.

[0030] The middle and both sides of the track groove 71 are horizontal grooves, and the horizontal grooves on both sides are connected to the horizontal groove in the middle through an inclined groove. The setting of the track groove 71 provides a precise path for the movement of the slide bar 72.

[0031] In practical use, when the mounting shaft 64 starts to rotate, it drives the linkage rod B78 to move. The linkage rod B78 then drives the movable rod 79 to swing. The swing of the movable rod 79 causes the sliding shaft B710 to slide inside the rectangular frame 711, thereby pushing the rectangular frame 711 to move forward or backward along the fixed slide rail 712. The movement of the rectangular frame 711 is transmitted to the limiting frame 75, so that it slides within the specified track. As the limiting frame 75 moves, the slider B74 also moves accordingly. The slider B74 is connected to the sliding rod 72, so the sliding rod 72 moves back and forth in a straight line along the preset track groove 71. When the sliding rod 72 moves to the inclined groove part of the track groove 71, due to the design of the inclined groove, the sliding rod 72 will slide upward. At the same time, the slider B74 also moves upward inside the limiting frame 75. The upward movement of the slider B74 drives the cleaning rod 76 installed on its outer wall to extend out from the hidden movable groove 77. The extended cleaning rod 76 sweeps across the upper surface of the base 1 and pushes the broken wires and debris generated during the detection process into the collection box 713 below. After the test is completed, the operator can easily pull out the collection box 713 by simply holding the handle 714 on the collection box 713 to clean up the debris. This design ensures a clean environment for the equipment and improves the smoothness and efficiency of the entire testing process.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
