Description

Technical Field

[0001] The present invention relates to the technical field of submarine cables, and particularly to a tear resistance detection device for the production of semi-conductive cloth tapes for submarine cables. Background Art

[0002] A submarine cable is a cable wrapped with insulating materials and laid on the seabed for telecommunication transmission. Among them, the protection operation of optical fibers is mainly completed by using semi-conductive cloth tapes. The semi-conductive cloth tape is an electrical insulating material used for the binding and insulation of cable conductors or cores to ensure the stability and safety of the cable. It can also play a shielding role under the metal layer to prevent electromagnetic interference and the influence of external electromagnetic fields, and has flame retardant properties to help prevent the spread of fires. At the same time, it plays a buffering role on the metal layer to protect the cable from damage caused by external pressure and impact.

[0003] During the production process of semi-conductive cloth tapes, it is necessary to detect the tear resistance of the semi-conductive cloth tapes. Currently, a tear tester is mainly used for detection. The semi-conductive cloth tape is installed in the tear tester, and the corresponding weights are installed, and then the detection operation can be started. The overall operation is simple. However, in the actual detection process, the traditional tear tester can only complete the clamping and fixing operation of the semi-conductive cloth tape. Before installing the semi-conductive cloth tape, it is necessary to manually smooth the semi-conductive cloth tape to reduce the possibility of wrinkles in the semi-conductive cloth tape, thereby ensuring the normal detection effect. And during the detection process, it is also necessary to manually detect the semi-conductive cloth tape to prevent the possibility of filaments remaining connected, that is, the semi-conductive cloth tape may not be in a completely torn state, resulting in a certain error in the experimental measurement results. Finally, during the installation of the weights, it is necessary to manually fix the weights. The overall operation is time-consuming and laborious, and the overall workload is large. Therefore, a tear resistance detection device for the production of semi-conductive cloth tapes for submarine cables is provided. Summary of the Invention

Specific implementation mode

[0025] As Figures 1-8 shown, this embodiment provides a technical solution: an anti-tearing detection device for the production of semi-conductive cloth tape for submarine cables, including a body 1, a display screen 2 fixedly connected to the front side of the body 1, a rotating shaft 3 rotatably connected to the side wall of the body 1, a rotating plate 4 fixedly connected to the outside of the rotating shaft 3, a main fixed rod 9 fixedly connected to the side wall of the rotating plate 4, an auxiliary fixed rod 12 also fixedly connected to the side wall of the rotating plate 4, a grip 5 fixedly connected to the upper side of the rotating shaft 3, a cutting knife 11 rotatably connected to the side wall of the body 1, and further including: a clamping component.

[0026] First, install the semi-conductive cloth tape to be detected in the clamping component, then select a suitable test weight, install the corresponding weight sleeve on the outside of the main fixed rod 9 and the auxiliary fixed rod 12, then start the cutting knife 11 to cut the semi-conductive cloth tape to make a notch in the semi-conductive cloth tape, and then release the grip 5. At this time, under the action of the weight, the rotating plate 4 rotates around the rotating shaft 3 to start the anti-tearing detection operation, and the obtained data is transmitted to the display screen 2, thereby completing the anti-tearing detection operation on the semi-conductive cloth tape. The above are all prior arts and will not be elaborated further.

[0027] As Figure 3 、 Figure 4 、 Figure 5 、 Figure 7, the clamping component includes a fixed frame 6 fixedly installed on the upper sides of the body 1 and the rotating plate 4. A first electric push rod 24 is fixedly connected to the inner side wall of the fixed frame 6. The output end of the first electric push rod 24 is fixedly connected to a moving frame 14. A moving plate 13 is fixedly connected to the side wall of the moving frame 14. The moving plate 13 penetrates through the fixed frame 6 and is slidably connected to the fixed frame 6. A transmission rack 28 is slidably sleeved inside the moving frame 14. A pressing plate 15 is fixedly connected to the side of the transmission rack 28 away from the moving frame 14. A sliding plate 30 is slidably sleeved inside the transmission rack 28. The sliding plate 30 is fixedly connected to the inner wall of the moving frame 14. A spring 31 is fixedly connected between the sliding plate 30 and the transmission rack 28.

[0028] First, place the semi-conductive cloth tape to be detected between the pressing plate 15 and the fixed frame 6. Start the first electric push rod 24. The first electric push rod 24 drives the moving frame 14 to move. The moving frame 14 drives the pressing plate 15 to move through the sliding plate 30 and the spring 31. When the pressing plate 15 abuts against the semi-conductive cloth tape, the pressing plate 15, the semi-conductive cloth tape and the fixed frame 6 are tightly connected. At this time, under the blocking effect of the fixed frame 6, the pressing plate 15 stops moving. However, at this time, the first electric push rod 24 will still drive the moving frame 14 and the sliding plate 30 to move. Therefore, the spring 31 will be compressed until the pressing plate 15, the moving frame 14, the semi-conductive cloth tape and the fixed frame 6 are tightly connected together, thus completing the clamping and fixing operation of the semi-conductive cloth tape. Rubber sleeves are fixedly sleeved on the side walls of the two fixed frames 6 and the moving frame 14.

[0029] As Figure 6 , a guiding component for the semi-conductive cloth tape is installed on the upper side of the pressing plate 15. The guiding component includes a regulating plate 22. Multiple groups of inclined plates 23 are evenly and fixedly connected to the side wall of the regulating plate 22. A threaded rod 20 is rotatably connected inside the moving frame 14. A transmission gear 21 is fixedly sleeved on the outer side of the threaded rod 20. The transmission gear 21 meshes with the transmission rack 28. A threaded cylinder 19 is threadedly sleeved on the outer side of the threaded rod 20. Two groups of sliding rods 29 are symmetrically and fixedly connected to the side wall of the threaded cylinder 19. A limiting frame 27 is fixedly connected to the side wall of the regulating plate 22. The sliding rods 29 are slidably connected to the limiting frame 27. Inclined grooves 25 are opened on both sides inside the moving frame 14. Two inclined rods 26 are slidably connected inside the two inclined grooves 25. The inclined rods 26 are fixedly connected to the limiting frame 27.

[0030] First, the inclined groove 25 is inclined, and the included angle between the inclined groove 25 and the bottom surface of the moving frame 14 is 45°. When the pressing plate 15, the semi-conductive cloth tape and the fixed frame 6 are tightly connected, at this time, under the blocking effect of the fixed frame 6, the pressing plate 15 stops moving. However, at this time, the first electric push rod 24 still drives the moving frame 14 and the sliding plate 30 to move, so the spring 31 will be compressed. At this time, the transmission rack 28 moves relative to the moving frame 14, and the transmission rack 28 drives the transmission gear 21 to rotate. The transmission gear 21 drives the threaded rod 20 to rotate. Under the limiting effect of the limiting frame 27 and the sliding rod 29, and under the action of the inclined groove 25 and the inclined rod 26, the threaded barrel 19 can only move upward, and the upward moving threaded barrel 19 will drive the limiting frame 27 and the regulating plate 22 to move along the direction of the cooperation between the inclined groove 25 and the inclined rod 26. Since the included angle between the inclined groove 25 and the bottom surface of the moving frame 14 is 45°, the movement of the regulating plate 22 moving leftward relative to the moving frame 14 cancels out the movement of the moving frame 14 moving rightward relative to the fixed frame 6, resulting in the regulating plate 22 moving upward relative to the fixed frame 6. And due to the inclined setting of the inclined plate 23, the upward moving regulating plate 22 drives the inclined plate 23 to move upward. The inclined plate 23 abuts against the semi-conductive cloth tape, preventing the semi-conductive cloth tape from wrinkling, thereby improving the accuracy of the detection result.

[0031] As Figure 8 , a transmission rod 34 is rotatably connected to the outside of the moving frame 14. A semi-gear 16 is fixedly sleeved on the outside of the transmission rod 34. A connecting rack 33 is slidably sleeved up and down on the outside of the fixed frame 6. The semi-gear 16 and the connecting rack 33 are meshed with each other. One end of the transmission rod 34 far from the fixed frame 6 is fixedly connected with a stop rod 17. A connecting rod 32 is fixedly connected to the side wall of the connecting rack 33. The connecting rod 32 passes through the threaded barrel 19 and is slidably connected with the threaded barrel 19.

[0032] First, since the connecting rack 33 is slidably connected with the fixed frame 6 up and down, and the connecting rod 32 passes through one side wall of the threaded barrel 19 and is slidably connected with the threaded barrel 19, the upward moving threaded barrel 19 will drive the connecting rack 33 to move upward through the connecting rod 32. The connecting rack 33 drives the semi-gear 16 to rotate counterclockwise. The semi-gear 16 drives the transmission rod 34 and the stop rod 17 to rotate counterclockwise around the transmission rod 34. When the connection between the connecting rack 33 and the semi-gear 16 is disconnected, the stop rod 17 is located above the semi-conductive cloth tape at this time. At this time, under the action of its own gravity, the stop rod 17 abuts against the semi-conductive cloth tape. When performing the tear resistance detection operation, if the semi-conductive cloth tape is torn completely, both stop rods 17 will lose the restriction of the semi-conductive cloth tape and move vertically downward. If the tear is incomplete, the stop rod 17 cannot return to its original position under the blocking effect of the semi-conductive cloth tape. Therefore, the actual tear situation can be observed by watching the position of the stop rod 17, and no manual secondary inspection is required.

[0033] AsFigure 2 , Figure 8 , on the side walls of both groups of fixed frames 6 are fixedly connected with sensors 18. The sensors 18 face the baffle 10. On the side wall of the rotating plate 4, two groups of extension rods 7 are symmetrically and fixedly connected. On the side walls of the two groups of extension rods 7 are fixedly connected with second electric push rods 8. The output end of the second electric push rod 8 is fixedly connected with a baffle 10. The baffle 10 faces the main fixed rod 9 or the auxiliary fixed rod 12.

[0034] First, the sensor 18 is an ordinary resistive sensor. When the two rotating plates 4 are perpendicular downward, the rotating plate 4 abuts against the sensor 18. The sensor 18 can emit corresponding electrical signals to start the second electric push rod 8, so that the two second electric push rods 8 move away from the rotating plate 4. The second electric push rod 8 drives the baffle 10 to move, expanding the distance between the baffle 10 and the main fixed rod 9 or the auxiliary fixed rod 12, so that the weights can be sleeved on the outside of the main fixed rod 9 or the auxiliary fixed rod 12. When the connection between the shift lever 17 and the sensor 18 is disconnected, the sensor 18 emits different electrical signals, causing the second electric push rod 8 to move towards the rotating plate 4. The second electric push rod drives the baffle 10 to move, shortening the distance between the baffle 10 and the main fixed rod 9 or the auxiliary fixed rod 12, so that the weights will not fall off the main fixed rod 9 or the auxiliary fixed rod 12. There is no need for manual operation to fix the weights, reducing the workload.

[0035] In the present invention, the semi-conductive cloth tape to be detected is placed between the pressing plate 15 and the fixed frame 6. The first electric push rod 24 is started. The first electric push rod 24 drives the moving frame 14 to move. The moving frame 14 drives the pressing plate 15 to move through the sliding plate 30 and the spring 31. When the pressing plate 15 abuts against the semi-conductive cloth tape, the pressing plate 15, the semi-conductive cloth tape and the fixed frame 6 are tightly connected. At this time, under the blocking effect of the fixed frame 6, the pressing plate 15 stops moving. However, at this time, the first electric push rod 24 still drives the moving frame 14 and the sliding plate 30 to move. Therefore, the spring 31 will be compressed. At this time, the transmission rack 28 moves relative to the moving frame 14. The transmission rack 28 drives the transmission gear 21 to rotate. The transmission gear 21 drives the threaded rod 20 to rotate. Under the limiting effect of the limiting frame 27 and the sliding rod 29, and under the action of the inclined groove 25 and the inclined rod 26, the threaded barrel 19 can only move upward. And the upward-moving threaded barrel 19 will drive the limiting frame 27 and the regulating plate 22 to move along the direction of the cooperation between the inclined groove 25 and the inclined rod 26. Since the included angle between the inclined groove 25 and the bottom surface of the moving frame 14 is 45°, the movement of the regulating plate 22 moving left relative to the moving frame 14 cancels out the movement of the moving frame 14 moving right relative to the fixed frame 6, resulting in the regulating plate 22 moving upward relative to the fixed frame 6. And due to the inclined setting of the inclined plate 23, the upward-moving regulating plate 22 drives the inclined plate 23 to move upward. The inclined plate 23 abuts against the semi-conductive cloth tape, preventing the semi-conductive cloth tape from wrinkling, and thus improving the accuracy of the detection result.

[0036] Moreover, the upward-moving threaded cylinder 19 will drive the connecting rack 33 to move upward through the connecting rod 32. The connecting rack 33 drives the half gear 16 to rotate counterclockwise. The half gear 16 drives the transmission rod 34 and the shift lever 17 to rotate counterclockwise around the transmission rod 34. When the connection between the connecting rack 33 and the half gear 16 is disconnected, the shift lever 17 is located above the semi-conductive cloth tape at this time. At this time, under the action of its own gravity, the shift lever 17 abuts against the semi-conductive cloth tape.

[0037] Start the cutting knife 11 to cut the semi-conductive cloth tape, making a notch on the semi-conductive cloth tape. Then release the grip 5. At this time, under the action of the weight, the rotating plate 4 rotates around the rotating shaft 3, and the anti-tearing detection operation starts. And the obtained data is transmitted to the display screen 2, thereby completing the anti-tearing detection operation on the semi-conductive cloth tape. The above are all prior arts and will not be elaborated further.

[0038] When performing the anti-tearing detection operation, if the tearing of the semi-conductive cloth tape is completed, both shift levers 17 lose the restriction of the semi-conductive cloth tape and move vertically downward. If the tearing is incomplete, the shift lever 17 cannot return to its original position under the blocking effect of the semi-conductive cloth tape. Thus, the actual tearing situation can be observed by watching the position of the shift lever 17, and no manual secondary inspection is required.

[0039] When the two rotating plates 4 move vertically downward, the rotating plates 4 abut against the sensors 18. The sensors 18 can emit corresponding electrical signals to start the second electric push rods 8, causing the two second electric push rods 8 to move away from the rotating plates 4. The second electric push rods 8 drive the baffles 10 to move, expanding the distance between the baffles 10 and the main fixed rod 9 or the auxiliary fixed rod 12, so that the weight can be sleeved outside the main fixed rod 9 or the auxiliary fixed rod 12. When the connection between the shift lever 17 and the sensor 18 is disconnected, the sensor 18 emits different electrical signals, causing the second electric push rods 8 to move toward the rotating plates 4. The second electric push rods drive the baffles 10 to move, shortening the distance between the baffles 10 and the main fixed rod 9 or the auxiliary fixed rod 12, so that the weight will not fall off the main fixed rod 9 or the auxiliary fixed rod 12, eliminating the need for manual fixation of the weight and reducing the workload.
