Detailed Description of the Embodiment

[0024] The following further describes the present application in detail Figures 1-4 with reference to the accompanying drawings.

[0025] The embodiment of the present application discloses an elevator wire rope strength detection device. Refer to Figures 1-4, An elevator steel wire rope strength detection device, including a base 1. A mounting frame 2 is fixedly connected to the outer wall of the top of the base 1. A winding roller 5 is rotatably connected to the inner wall of the middle section at the bottom of the mounting frame 2. A tension sensor 3 is fixedly installed on the outer wall of the middle section at the top of the base 1. A base 17 is fixedly connected to the outer wall of the top of the tension sensor 3. The outer wall of the mounting frame 2 is slidably connected with a protective cover 14 through a plurality of first sliders 15. A lifting component for driving the lifting and protection of the protective cover 14 is installed on the outer wall of the mounting frame 2. The lifting component includes two sprockets 10 rotatably connected to the outer wall of one side of the mounting frame 2. A chain 11 is installed in cooperation with the outer walls of the two sprockets 10. A stepping motor 13 is fixedly installed on the outer wall of one side of the base 1 through a bracket 12. The end of the output shaft of the stepping motor 13 is fixedly connected to the outer wall of the axis of one of the sprockets 10. A connecting block 16 is fixedly connected to the outer wall of one side of the chain 11. The connecting block 16 is fixedly connected to the inner wall of the bottom end of one side of the protective cover 14.

[0026] Refer to Figure 1 , A data processing unit 4 is installed on the outer wall of the base 1. The data processing unit 4 is electrically connected to the tension sensor 3. A microprocessor is integrated inside the data processing unit 4. A display and buttons are installed on its outer wall. The data collected by the tension sensor 3 is transmitted into the data processing unit 4 and analyzed and processed by the microprocessor integrated in the data processing unit 4 to obtain the strength detection result of the steel wire rope, which is visually displayed through its external display screen.

[0027] Refer to Figure 3 , A clamping mechanism for fixing the elevator rope is installed on the outer wall of the base 17. The clamping mechanism includes a fixed block 18 and a moving block 20. The fixed block 18 and the moving block 20 correspond to each other. The fixed block 18 is fixedly connected to the outer wall of the top of the base 17. A second slider 19 is slidably connected to the inner wall of the base 17. The moving block 20 is fixedly connected to the outer wall of the top of the second slider 19. Clamping blocks 22 are fixedly connected to the opposite outer walls of the fixed block 18 and the moving block 20. Two locking members 23 are threadedly connected to the outer wall of the fixed block 18. The ends of the locking members 23 penetrate through the clamping blocks 22. A plurality of arc-shaped grooves are provided on the opposite outer walls of the two clamping blocks 22. Through the arc-shaped grooves, the clamping blocks 22 can be closely attached to the outer wall of the elevator rope, enabling the clamping blocks 22 to better wrap and clamp the elevator rope. Therefore, we can lay the elevator rope in a snake-like manner between the plurality of arc-shaped grooves between the two clamping blocks 22, which can significantly increase the contact area between the clamping blocks 22 and the elevator rope and greatly increase the friction force during clamping. In addition, by rotating the two locking members 23, the ends of the two locking members 23 can be abutted against the elevator rope, thereby locking the elevator rope in the clamping blocks 22;

[0028] The clamping mechanism further includes a cylinder 21 fixedly installed on the outer wall of one side of the base 17. The output end of the cylinder 21 penetrates through the base 17 and is fixedly connected to the second slider 19. The output end of the cylinder 21 can quickly push the second slider 19 to move close to the fixed block 18. Then, the second slider 19 drives the moving block 20 to move close to the fixed block 18. At this time, the two clamping blocks 22 cooperate to clamp the elevator rope.

[0029] Referring to Figure 2 , a winding mechanism for driving the winding roller 5 to rotate is installed on the outer wall of the mounting frame 2. The winding mechanism includes a connecting shaft 6 rotatably connected to the inner wall of one side of the mounting frame 2. One end of the connecting shaft 6 penetrates through the mounting frame 2 and is fixedly connected to one end of the winding roller 5. The other end of the connecting shaft 6 penetrates through the mounting frame 2 and is fixedly connected with a worm gear 7. The winding mechanism further includes a worm 8 rotatably connected to the outer wall of one side of the mounting frame 2 through a shaft seat. The worm 8 meshes with the worm gear 7. A servo motor 9 is fixedly installed on the outer wall of one side of the mounting frame 2. The end of the output shaft of the servo motor 9 is fixedly connected to one end of the worm 8. The other end of the elevator rope is wound around the winding roller 5. By driving the worm 8 to rotate through the servo motor 9, the worm 8 can drive the meshing worm gear 7 to rotate. The worm gear 7 then drives the winding roller 5 to rotate through the connecting shaft 6 to wind the other end of the elevator rope. During the winding process of the elevator rope, it will be tightened and generate a pulling force, thereby realizing the detection of the tensile strength of the elevator rope.

[0030] The implementation principle of an elevator steel wire rope strength detection device according to an embodiment of the present application is as follows: When in use, one end of the elevator rope is laid in a serpentine manner on the outer wall of the clamping block 22 located on the outer wall of the fixed block 18, so that the elevator rope is embedded in a plurality of arc-shaped grooves, and the cylinder 21 is started. The output end of the cylinder 21 can quickly push the second slider 19 to move close to the fixed block 18. Then, the second slider 19 drives the moving block 20 to move close to the fixed block 18. At this time, the two clamping blocks 22 cooperate to clamp the elevator rope. In addition, two locking members 23 can be screwed. The ends of the two locking members 23 are in contact with the elevator rope to firmly lock the elevator rope in the two clamping blocks 22. Then, the other end of the elevator rope is wound around the winding roller 5 to complete the installation of the elevator rope;

[0031] Then, through the lifting assembly, the stepping motor 13 is started. The output shaft of the stepping motor 13 drives one sprocket 10 to rotate. The two sprockets 10 then rotate synchronously through the chain 11. At this time, the chain 11 drives the connecting block 16 to move up and down. The connecting block 16 drives the protective cover 14 to slide up and down on the outer wall of the mounting frame 2 through a plurality of first sliders 15. When the protective cover 14 descends, it blocks the elevator rope to be detected inside, playing a protective role and preventing the damage caused by the breakage of the elevator rope;

[0032] At this time, the elevator rope can be detected by the rewinding mechanism. The servo motor 9 is started, and the output shaft of the servo motor 9 drives the worm 8 to rotate. The worm 8 then drives the meshing worm wheel 7 to rotate. The worm wheel 7 drives the winding roller 5 to rotate through the connecting shaft 6 to wind the elevator rope. The elevator rope is tightened and generates a tensile force, which is detected and collected by the tensile force sensor 3 in real time. The collected data is transmitted into the data processing unit 4 and analyzed and processed by the microprocessor integrated in the data processing unit 4 to obtain the strength detection result of the steel wire rope, which is visually displayed through its external display screen, thus completing the overall detection process.
