Description

Technical Field

[0001] The utility model relates to the technical field of cable detection, in particular to a cable tension testing device. Background Art

[0002] In addition to being light in specific gravity, high in strength, resistant to impact and wear, cables also have the advantages of corrosion resistance, mildew resistance, and insect resistance. For example, the strength and wear resistance of nylon cables exceed those of hemp and cotton cables by several times, and the specific gravity of polypropylene cables is less than that of water, so they can float on the water surface, making the operation convenient and safe. In addition to being used for ship mooring cables, they are also widely used in transportation.

[0003] After the cable is produced, it needs to be subjected to tension testing. When the existing testing devices are in use, it is inconvenient to clamp and fix both ends of the cable, making it difficult to ensure that the resultant force direction of the cable is downward, with troublesome operation and inconvenient use. Therefore, we propose a cable tension testing device. Summary of the Utility Model

A long groove located between the two support blocks is opened at the top of the box body. An auxiliary testing mechanism is arranged on the hollow block, and rotating mechanisms connected to the auxiliary testing mechanism are arranged on both sides of the hollow block. Clamping mechanisms are arranged on the two rotating mechanisms.

[0007] Preferably, the auxiliary testing mechanism includes a connecting rod penetrating through the top of the hollow block. A tension wheel is fixedly installed at one end of the connecting rod outside the hollow block, a connecting block is fixedly installed at one end of the connecting rod inside the hollow block, a pressure sensor is arranged at the inner bottom of the hollow block, a spring is fixedly connected between the pressure sensor and the connecting block, a servo motor is fixedly installed at the bottom of the hollow block, and a worm is fixedly connected to the output shaft of the servo motor.

Specific Embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Refer to Figures 1 - 3, a cable tension testing device, including a box body 1. Two support blocks 11 are fixedly installed on the top of the box body 1. The same hollow block 10 is fixedly installed on the tops of the two support blocks 11. A long groove 2 located between the two support blocks 11 is opened on the top of the box body 1. An auxiliary testing mechanism is arranged on the hollow block 10. The auxiliary testing mechanism includes a connecting rod 9 penetrating through the top of the hollow block 10. One end of the connecting rod 9 outside the hollow block 10 is fixedly installed with a tension wheel 8. One end of the connecting rod 9 inside the hollow block 10 is fixedly installed with a connecting block 16. A pressure sensor 18 is arranged on the inner bottom of the hollow block 10. A spring 17 is fixedly connected between the pressure sensor 18 and the connecting block 16. A servo motor 15 is fixedly installed on the bottom of the hollow block 10. The output shaft of the servo motor 15 is fixedly connected with a worm 14;

[0020] Rotating mechanisms connected to the auxiliary testing mechanism are arranged on both sides of the hollow block 10. The rotating mechanism includes a rotating shaft 13 rotatably connected between the inner walls of both sides of the long groove 2. A worm gear 12 meshing with the worm 14 is fixedly installed on the outer side wall of the rotating shaft 13. A rotating rod 7 is fixedly installed on the outer side wall of the rotating shaft 13;

[0021] Clamping mechanisms are arranged on both rotating mechanisms. The clamping mechanism includes two fixed blocks 4 fixedly installed on the side wall of one end of the rotating rod 7 away from the rotating shaft 13. Screws 6 penetrating through and threadedly connected with the two fixed blocks 4 are arranged on both fixed blocks 4. One ends of the two screws 6 close to each other are rotatably connected with clamping blocks 3. Both clamping blocks 3 are slidably connected with the side wall of one end of the rotating rod 7 away from the rotating shaft 13. Knobs 5 are fixedly installed on one ends of the two screws 6 away from each other.

[0022] When the utility model is used, both ends of a cable sample are respectively passed between two clamping blocks 3 on both sides of the tension wheel 8. The middle part of the cable sample is located above the tension wheel 8. By rotating the knob 5, the screw 6 can be rotated. Since the screw 6 is rotatably connected with the clamping block 3 and the clamping block 3 is slidably connected with the side wall of one end of the rotating rod 7, the clamping block 3 cannot rotate. Thus, the two clamping blocks 3 on the same side of the tension wheel 8 can be made to approach each other, so as to clamp and fix both ends of the cable. Subsequently, the servo motor 15 is started to rotate the worm 14. By the meshing of the worm 14 and the worm gear 12, the worm gear 12 rotates. The rotation of the worm gear 12 drives the rotating shaft 13 and the rotating rod 7 to rotate, so as to pull both ends of the cable downward, making the resultant force direction of the cable sample downward along the connecting rod 9. The connecting rod 9 transmits the force received through the spring 17 to the pressure sensor 18. The pressure sensor 18 transmits the pressure signal to an external device through a data line to complete the detection. The wiring and working principle of the pressure sensor 18 are prior art and will not be elaborated.

[0023] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes, shall be covered by the protection scope of the present utility model.
