Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1
[0024] Combination Figures 1-4 A cable strength testing device for use in ports includes a base 1, two support plates 2 fixedly installed on one side of the top of the base 1, an active roller 3 movably installed between the two support plates 2, a reduction motor 4 installed on the outer side of one of the support plates 2, a fixing mechanism 5 installed between the two support plates 2 and the top of the base 1, and a protective mechanism 6 installed at the rear end of the top of the base 1.
[0025] See Figure 2 and Figure 3 Furthermore, the fixing mechanism 5 includes two sets of sliding rods 7, which are respectively fixedly installed between the top of the two support plates 2 and the base 1. Fixing rods 8 are fixedly installed on the inner side of the two support plates 2, and pressure sensors 9 are installed at the ends of the fixing rods 8. Slider blocks 10 are movably installed on the outside of the two sets of sliding rods 7. A positioning box 11 is fixedly installed on the outside of one of the sliders 10. A passive roller 12 is movably installed between the two sliders 10. A rotating tooth 13 is installed at one end of the rotating shaft of the passive roller 12 and inside the positioning box 11. A rocker plate 14 is fixedly connected to the outside of the rotating tooth 13. A pressure rod 15 is movably installed through the top of the positioning box 11. A pressure block 16 is fixedly installed at the bottom end of the pressure rod 15. A spring 17 is sleeved on the outside of the pressure rod 15.
[0026] The reduction output shaft of the reduction motor 4 is fixedly connected to the active roller 3. Several positioning posts are provided on the outside of both the active roller 3 and the passive roller 12. The active roller 3 is driven to rotate by the reduction motor 4. The outside of the active roller 3 and the passive roller 12 is used to wind the net rope, and the winding is fixed by the external positioning posts.
[0027] The slider 10 is located outside the slide bar 7 and is slidably arranged. The passive roller 12, the rotating tooth 13 and the rocker plate 14 are fixedly connected. The rocker plate 14 drives the passive roller 12 to rotate so as to wind the net rope.
[0028] The bottom of the pressure block 16 is provided with a toothed groove, and the pressure block 16 and the rotating tooth 13 are meshed with each other. Under the action of the spring 17, the pressure rod 15 drives the pressure block 16 to slide downward and mesh with the rotating tooth 13, so that the passive roller 12 is automatically fixed.
[0029] Specifically, by winding one end of the net rope around the outside of the passive roller 12, pulling the pressure rod 15 upward to disengage the pressure block 16 from the rotating tooth 13, and rotating the passive roller 12 by shaking the rocker 14, the other end of the net rope is wound around the outside of the active roller 3. The active roller 3 is driven to rotate by the reduction motor 4, which stretches the net rope and detects the stretching pressure by the pressure sensor 9.
[0030] Example 2
[0031] See Figure 4 Furthermore, based on Embodiment 1, the protective mechanism 6 includes a protective plate 18, which is movably installed at the rear of the base 1 and the support plate 2. Positioning blocks 19 are fixedly installed at the top of the rear of both the base 1 and the support plate 2. A lifting cylinder 20 is movably installed on the outer side of the base 1. The bottom end of the lifting cylinder 20 and the top end of the telescopic rod are connected to the base 1 and the protective plate 18 respectively through a support shaft 21.
[0032] The protective plate 18 is connected to the base 1 and the support plate 2 by a hinge. The protective plate 18 covers the top of the base 1 and matches each other. The protective plate 18 can be rotated to open or close by the hinge, and the protective plate 18 provides protection for the interior of the base 1.
[0033] The bottom end of the lifting cylinder 20 is rotatably connected to the base 1 via the support shaft 21. The top end of the telescopic rod of the lifting cylinder 20 is movably connected to the middle part of one side of the protective plate 18 via the support shaft 21. The telescopic rod of the lifting cylinder 20 drives the protective plate 18 to rotate, thus automatically opening and closing.
[0034] Specifically, the lifting cylinder 20 drives the protective plate 18 to rotate and cover the top of the base 1 to prevent the internal net rope from breaking and splashing outward during the test. The lifting cylinder 20 lifts the protective plate 18 and rotates it through the support shaft 21. The protective plate 18 is blocked to a vertical state by the positioning block 19, opening the top of the base 1 to facilitate the installation and removal of the net rope.
[0035] In actual operation, the top of the base 1 is opened, and the two ends of the net rope are respectively wound around the passive roller 12 and the active roller 3. The tension is detected by the pressure sensor 9 to detect the strength of the net rope.
[0036] When winding and fixing, one end of the net rope is wound around the outside of the passive roller 12. The pressure rod 15 is pulled upward to disengage the pressure block 16 from the rotating tooth 13. The passive roller 12 is rotated by shaking the rocker 14, and the net rope is wound around the outside. The pressure rod 15 slides downward under the action of the spring 17, so that the bottom of the pressure block 16 engages with the rotating tooth 13 for fixing. Then the other end of the net rope is wound around the outside of the active roller 3. The active roller 3 is rotated by the reduction motor 4, so that the net rope is stretched by winding through the active roller 3. The two sliders 10 slide and contact the two pressure sensors 9. The pressure sensors 9 detect the stretching pressure. When the pressure detected by the two pressure sensors 9 reaches the preset pressure value, the reduction motor 4 stops the active roller 3 from rotating, and the net rope is observed to see if it is qualified or broken.
[0037] During protection, the lifting cylinder 20 drives the protective plate 18 to rotate and cover the top of the base 1, preventing the internal net rope from breaking and splashing outwards during the test. The extension rod of the lifting cylinder 20 extends to lift the protective plate 18. The bottom end of the lifting cylinder 20 and the top end of the extension rod are rotated through the support shaft 21. The protective plate 18 is blocked to a vertical state by the positioning block 19, opening the top of the base 1 to facilitate the installation and removal of the net rope.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
