Description

Technical Field

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

[0002] Submarine cable is an electric cable wrapped with insulating material, laid on the seabed and used for telecommunication transmission. Semiconductive tape is mainly used to protect optical fiber. Semiconductor tape is an electrical insulating material used for 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. It has flame retardant properties, which helps prevent the spread of fire. At the same time, it plays a buffering role in the metal layer to protect the cable from damage by external pressure and impact.

[0003] In the production process of semi-conductive tapes, it is necessary to test the tear resistance of the semi-conductive tapes. At present, the tear resistance instrument is mainly used for testing. The semi-conductive tapes are installed in the tear resistance instrument, the corresponding weights are installed, and the testing operation is started. The overall operation is simple, but in the actual testing process, the traditional tear resistance instrument can only complete the clamping and fixing operation of the semi-conductive tape. Before the installation of the semi-conductive tape, the semi-conductive tape needs to be smoothed manually to reduce the possibility of wrinkles on the semi-conductive tape, thereby ensuring the normal testing effect. In the process of testing, the semi-conductive tape needs to be tested manually to prevent the possibility of broken threads, that is, the semi-conductive tape may not be in a completely torn state, resulting in certain errors in the experimental results. Finally, in the process of installing the weights, the weights need to be fixed manually. The overall operation is time-consuming and laborious, and the overall workload is large. Therefore, a tear resistance testing device for the production of semi-conductive tapes for submarine cables is provided. Summary of the invention

DETAILED DESCRIPTION

[0015] like Figure 1-Figure 8 As shown, this embodiment provides a technical solution: an anti-tear detection device for the production of semi-conductive cloth tapes for submarine cables, comprising a main body 1, a display screen 2 is fixedly connected to the front side of the main body 1, a side wall of the main body 1 is rotatably connected to a rotating shaft 3, a rotating plate 4 is fixedly connected to the outer side of the rotating shaft 3, a main fixing rod 9 is fixedly connected to the side wall of the rotating plate 4, a secondary fixing rod 12 is also fixedly connected to the side wall of the rotating plate 4, a handle 5 is fixedly connected to the upper side of the rotating shaft 3, a cutting knife 11 is rotatably connected to the side wall of the main body 1, and also includes: a clamping assembly.

[0016] First, install the semi-conductive cloth tape to be tested in the clamping assembly, then select a suitable test weight, install the corresponding weight 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 handle 5. At this time, under the action of the weight, the rotating plate 4 rotates around the rotating shaft 3, and the tear resistance detection operation begins, and the obtained data is transmitted to the display screen 2, thereby completing the tear resistance detection operation of the semi-conductive cloth tape. The above are all existing technologies and no unnecessary elaboration is made.

[0017] like Figure 3 , Figure 4 , Figure 5 , Figure 7 The clamping assembly includes a fixed frame 6 fixedly installed on the main body 1 and the upper side of the rotating plate 4, the inner side wall of the fixed frame 6 is fixedly connected to the first electric push rod 24, the output end of the first electric push rod 24 is fixedly connected to the moving frame 14, the side wall of the moving frame 14 is fixedly connected to the moving plate 13, the moving plate 13 penetrates the fixed frame 6 and is slidably connected to the fixed frame 6, a transmission rack 28 is slidably sleeved in the moving frame 14, and the side of the transmission rack 28 away from the moving frame 14 is fixedly connected to the extrusion plate 15; a slide plate 30 is slidably sleeved in the transmission rack 28, the slide plate 30 is fixedly connected to the inner wall of the moving frame 14, and a spring 31 is fixedly connected between the slide plate 30 and the transmission rack 28.

[0018] First, place the semi-conductive tape to be tested between the squeezing 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, and the moving frame 14 drives the squeezing plate 15 to move through the slide plate 30 and the spring 31. When the squeezing plate 15 and the semi-conductive tape are against each other, the squeezing plate 15, the semi-conductive tape and the fixed frame 6 are tightly connected. At this time, under the obstruction of the fixed frame 6, the squeezing plate 15 stops moving, but at this time the first electric push rod 24 will also drive the moving frame 14 and the slide plate 30 to move, so it will compress the spring 31 until the squeezing plate 15, the moving frame 14, the semi-conductive tape and the fixed frame 6 are tightly connected together, thereby completing the clamping and fixing operation of the semi-conductive tape. The side walls of the two fixed frames 6 and the moving frame 14 are fixedly sleeved with rubber sleeves.

[0019] like Figure 6 A drainage component for the semi-conductive tape is installed on the upper side of the extrusion plate 15, and the drainage component includes a regulating plate 22. The side walls of the regulating plate 22 are evenly fixedly connected with multiple groups of inclined plates 23. A threaded rod 20 is rotatably connected in the moving frame 14. A transmission gear 21 is fixedly sleeved on the outer side of the threaded rod 20. The transmission gear 21 is meshed with a 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 fixedly connected to the side walls of the threaded cylinder 19. The side walls of the regulating plate 22 are fixedly connected to a limit frame 27. The sliding rod 29 is slidably connected to the limit frame 27. Oblique grooves 25 are opened on both sides of the moving frame 14. Oblique rods 26 are slidably connected in the two groups of oblique grooves 25. The oblique rods 26 are fixedly connected to the limit frame 27.

[0020] First, the inclined groove 25 is inclined, and the angle between the inclined groove 25 and the bottom surface of the moving frame 14 is 45°. When the extrusion plate 15, the semi-conductive cloth belt and the fixed frame 6 are tightly connected, the extrusion plate 15 stops moving under the obstruction of the fixed frame 6. However, the first electric push rod 24 will also drive the moving frame 14 and the slide plate 30 to move, thereby compressing the spring 31. 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 action of the limit frame 27 and the slide bar 29, and under the action of the inclined groove 25 and the inclined rod 26, the threaded rod 20 is The cylinder 19 can only move upward, and the upward moving threaded cylinder 19 will drive the limit frame 27 and the regulating plate 22 to move along the direction of the inclined groove 25 and the inclined rod 26. Since the 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 to the left relative to the moving frame 14 and the moving frame 14 moving to the right relative to the fixed frame 6 is offset, resulting in the regulating plate 22 moving upward relative to the fixed frame 6. Due to the inclined setting of the inclined plate 23, the upward moving regulating plate 22 drives the inclined plate 23 to move upward, and the inclined plate 23 and the semi-conductive tape are offset to prevent the semi-conductive tape from wrinkling, thereby improving the accuracy of the detection result.

[0021] like Figure 8 A transmission rod 34 is rotatably connected to the outer side of the movable frame 14, a half gear 16 is fixedly sleeved on the outer side of the transmission rod 34, a connecting rack 33 is slidably sleeved on the outer side of the fixed frame 6, the half gear 16 and the connecting rack 33 are meshed, and a shift rod 17 is fixedly connected to the end of the transmission rod 34 away from the fixed frame 6, and a connecting rod 32 is fixedly connected to the side wall of the connecting rack 33, and the connecting rod 32 passes through the threaded cylinder 19 and is slidably connected to the threaded cylinder 19.

[0022] First, since the connecting rack 33 and the fixed frame 6 are slidably connected up and down, and the connecting rod 32 passes through a side wall of the threaded cylinder 19 and is slidably connected to the threaded cylinder 19, the threaded cylinder 19 moving upward will drive the connecting rack 33 to move upward through the connecting rod 32, and the connecting rack 33 drives the half gear 16 to rotate counterclockwise, and the half gear 16 drives the transmission rod 34 and the gear rod 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 gear rod 17 is located on the upper side of the semi-conductive fabric tape. At this time, under the action of its own gravity, the gear rod 17 and the semi-conductive fabric tape are offset. When performing the tearing resistance detection operation, if the tearing of the semi-conductive fabric tape is completed, the two gear rods 17 lose the restriction of the semi-conductive fabric tape and move vertically downward. If the tearing is incomplete, the gear rod 17 cannot return to its original position due to the obstruction of the semi-conductive fabric tape. Then, the actual tearing situation can be observed by observing the position of the gear rod 17, and no manual secondary inspection is required.

[0023] like Figure 2 , Figure 8 The side walls of the two groups of fixed frames 6 are fixedly connected with sensors 18, and the sensors 18 are opposite to the baffle 10. The side walls of the rotating plate 4 are symmetrically fixedly connected with two groups of extension rods 7. The side walls of the two groups of extension rods 7 are fixedly connected with the second electric push rods 8. The output end of the second electric push rod 8 is fixedly connected with the baffle 10, and the baffle 10 is opposite to the main fixed rod 9 or the auxiliary fixed rod 12.

[0024] First, the sensor 18 is an ordinary resistive sensor. When the two rotating plates 4 are vertically downward, the rotating plates 4 and the sensor 18 are against each other. The sensor 18 can send a corresponding electrical signal 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, and expands the distance between the baffle 10 and the main fixed rod 9 or the secondary fixed rod 12, so that the weight can be sleeved on the outside of the main fixed rod 9 or the secondary fixed rod 12. When the connection between the gear lever 17 and the sensor 18 is disconnected, the sensor 18 sends a different electrical signal, so that the second electric push rod 8 moves toward the rotating plate 4. The second driving push rod drives the baffle 10 to move, shortening the distance between the baffle 10 and the main fixed rod 9 or the secondary fixed rod 12, so that the weight will not fall off the main fixed rod 9 or the secondary fixed rod 12, and there is no need to manually complete the fixing operation of the weight, thereby reducing the workload.

[0025] In the present invention, the semi-conductive cloth tape to be detected is placed between the extrusion plate 15 and the fixed frame 6, and the first electric push rod 24 is started. The first electric push rod 24 drives the moving frame 14 to move, and the moving frame 14 drives the extrusion plate 15 to move through the slide plate 30 and the spring 31. When the extrusion plate 15 and the semi-conductive cloth tape are against each other, the extrusion plate 15, the semi-conductive cloth tape and the fixed frame 6 are tightly connected. At this time, under the obstruction of the fixed frame 6, the extrusion plate 15 stops moving, but the first electric push rod 24 will also drive the moving frame 14 and the slide 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, and the transmission gear 21 drives the threaded rod 20 to rotate, and the limit frame 27 Under the limiting effect of the slide bar 29 and the action of the inclined groove 25 and the inclined rod 26, the threaded cylinder 19 can only move upward, and the upward moving threaded cylinder 19 will drive the limit 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 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 to the left relative to the moving frame 14 and the moving frame 14 moving to the right relative to the fixed frame 6 is offset, resulting in the regulating plate 22 moving upward relative to the fixed frame 6. Due to the inclined setting of the inclined plate 23, the upward moving regulating plate 22 drives the inclined plate 23 to move upward, and the inclined plate 23 and the semi-conductive tape are offset to prevent the semi-conductive tape from wrinkling, thereby improving the accuracy of the detection result.

[0026] In addition, the threaded cylinder 19 moving upward will drive the connecting rack 33 to move upward through the connecting rod 32, and the connecting rack 33 will drive the half gear 16 to rotate counterclockwise, and the half gear 16 will drive the transmission rod 34 and the gear rod 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 gear rod 17 is located on the upper side of the semi-conductive fabric tape. At this time, under the action of its own gravity, the gear rod 17 and the semi-conductive fabric tape are offset from each other.

[0027] Start the cutting knife 11 to cut the semi-conductive tape to make a notch in the semi-conductive tape, and then release the handle 5. At this time, under the action of the weight, the rotating plate 4 rotates around the rotating shaft 3, and the anti-tear detection operation begins. The obtained data is transmitted to the display screen 2, thereby completing the anti-tear detection operation of the semi-conductive tape. The above are all existing technologies and no unnecessary elaboration is made.

[0028] When performing the tearing resistance detection operation, if the tearing of the semi-conductive tape is complete, the two levers 17 will lose the restriction of the semi-conductive tape and move vertically downward; if the tearing is incomplete, the lever 17 cannot return to its original position due to the obstruction of the semi-conductive tape, and the actual tearing situation can be detected by observing the position of the lever 17 without the need for manual secondary inspection.

[0029] When the two rotating plates 4 are vertically downward, the rotating plates 4 and the sensor 18 are against each other, and the sensor 18 can send out a corresponding electrical signal to start the second electric push rod 8, so that the two second electric push rods 8 move away from the rotating plate 4, and the second electric push rod 8 drives the baffle 10 to move, and expands the distance between the baffle 10 and the main fixed rod 9 or the auxiliary fixed rod 12, so that the weight can be sleeved on the outside of the main fixed rod 9 or the auxiliary fixed rod 12. When the connection between the gear lever 17 and the sensor 18 is disconnected, the sensor 18 sends out a different electrical signal, so that the second electric push rod 8 moves toward the rotating plate 4, and the second driving 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 weight will not fall off the main fixed rod 9 or the auxiliary fixed rod 12, and there is no need to manually complete the fixing operation of the weight, thereby reducing the workload.
