Description

Technical Field

[0001] The present invention relates to the technical field of tensile deformation detection, in particular to a tensile deformation detection device for optical fiber and optical cable. Background Art

[0002] Optical fiber is the abbreviation of optical fiber. It is a fiber made of glass or plastic that can be used as a light transmission tool. Optical cable is manufactured to meet optical, mechanical or environmental performance specifications. It uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. The optical cable is mainly composed of optical fibers (glass fibers as thin as hair) and plastic protective sheaths and plastic outer sheaths. Metals such as gold, silver, copper and aluminum are provided in the optical cable. After the optical fiber is produced, various data of the optical fiber need to be tested. In particular, the optical fiber will be subjected to tension during use, and the tension will cause the optical fiber to deform. The optical fiber cable needs to be tested after stretching and deformation.

[0003] The optical fiber cable tensile deformation detection is mainly to measure the diameter of the optical fiber cable after stretching. However, the existing optical fiber cable tensile deformation detection devices mostly use workers to hold a vernier caliper for diameter detection. Workers are prone to measurement errors due to hand shaking during measurement. At the same time, workers cannot keep the measurements on the same horizontal plane, which reduces the measurement accuracy. In addition, the optical fiber cable after stretching is prone to deformation, such as bending or bulging. The existing optical fiber cable tensile deformation detection devices cannot reset the deformed optical fiber cable and the data obtained is inaccurate. Summary of the invention

[0006] There are two groups of detection circular plates, which form a circular ring for detecting optical fiber cables. A first measuring ruler for reading the diameter value of the optical fiber cable is fixedly connected to the surface of the detection circular plate. The end of the first measuring ruler away from the detection circular plate passes through the limit circular ring and extends to the outside of the limit circular ring.

[0007] As a further improvement of the technical solution, auxiliary plates are fixedly connected to both sides of the detection circular plate, and a spring is fixedly connected between the surface of the auxiliary plate and the inner cavity of the limiting circular ring.

[0008] As a further improvement of the present technical solution, it is characterized in that: a connecting rod is fixedly connected to one side of the detection circular plate and the upper and lower sides of the auxiliary plate, an end of the connecting rod away from the detection circular plate is fixedly connected to an inclined plate, one side of the inclined plate is fixedly connected to a docking plate, and the circular ring formed by the two groups of the docking plates is larger than the circular ring formed by the two groups of the detection circular plates.

[0009] As a further improvement of the present technical solution, two groups of extrusion plates for extruding and resetting the optical fiber cable are arranged at the top of the base plate and on one side of the limiting ring. The two groups of extrusion plates are semicircular, and the bottom of the extrusion plate is fixedly connected to a vertical plate, and the bottom of the vertical plate is fixedly connected to two groups of sliders. A sliding groove is provided at the top of the base plate and below the vertical plate, and the inner cavity of the sliding groove is slidably connected to the surface of the slider, and the bottom of the vertical plate is in contact with the top of the base plate.

[0010] As a further improvement of the technical solution, a fixed plate is fixedly connected to the top of the bottom plate and on one side of the vertical plate, a hydraulic cylinder is fixedly connected to the fixed plate, and a top plate is fixedly connected to the telescopic end of the hydraulic cylinder, and the curvature of the top plate surface is the same as the curvature of the extrusion plate surface.

[0011] As a further improvement of the present technical solution, one group of extrusion plates is fixedly connected to the top with a first vertical rod, one side of the first vertical rod is fixedly connected to a second measuring ruler, and another group of extrusion plates is fixedly connected to the top with a second vertical rod, the top of the second vertical rod is fixedly connected to a socket ring, and one end of the second measuring ruler passes through the inner cavity of the socket ring.

[0012] As a further improvement of the present technical solution, it is characterized in that: a mounting rod is fixedly connected to the surface of the extrusion plate, a first connecting rod is fixedly connected to one side of the mounting rod, one end of the first connecting rod is fixedly connected to a first tooth plate, the top of the base plate is rotatably connected to a rotating rod, the top of the rotating rod is fixedly connected to a gear, the surface of the gear is meshed with the surface of the first tooth plate, a second connecting rod is fixedly connected to one side of the docking plate, one end of the second connecting rod is fixedly connected to a second tooth plate, and the surface of the second tooth plate is meshed with the surface of the gear.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the optical fiber cable tensile deformation detection device, the stretched optical fiber cable is connected to the detection circular plate through the circular ring formed by two sets of docking plates. When the stretched optical fiber cable passes through the detection circular plate, the two sets of detection circular plates are stretched open, and the first measuring ruler is displaced. The diameter of the optical fiber cable after stretching is observed by the displacement of the first measuring ruler, and then compared with the diameter before stretching to detect the numerical change of the diameter of the optical fiber cable. In this way, the detection does not need to be done manually, and there will be no measurement error caused by hand shaking. The measurement can also be kept on the same horizontal plane, thereby improving the measurement accuracy.

[0015] 2. This type of device is used for detecting the tensile deformation of optical fiber cables. Before measuring the diameter of the optical fiber cables, the optical fiber cables are placed between two sets of extrusion plates. The top plate is moved by extending the hydraulic cylinder. The movement of the top plate causes the extrusion plates to exert pressure on the optical fiber cables. The bent or convex optical fiber cables can be flattened to keep the optical fiber cables in a cylindrical shape, which is convenient for subsequent diameter measurement and can obtain more accurate measurement data.

In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] See also Figure 1-Figure 8 As shown, the purpose of this embodiment is to provide a device for detecting tensile deformation of optical fiber cables, comprising a bottom plate 1, a support block 2 is fixedly connected to one side of the top of the bottom plate 1, a limiting circular ring 3 is fixedly connected to the top of the support block 2, and a detection circular plate 4 is arranged on the inner side of the limiting circular ring 3;

[0030] There are two groups of detection circular plates 4, and the two groups of detection circular plates 4 form a ring for detecting optical fiber cables. A first measuring ruler 5 for reading the diameter value of the optical fiber cable is fixedly connected to the surface of the detection circular plate 4. The end of the first measuring ruler 5 away from the detection circular plate 4 passes through the limit ring 3 and extends to the outside of the limit ring 3. Auxiliary plates 6 are fixedly connected to both sides of the detection circular plate 4. A spring 7 is fixedly connected between the surface of the auxiliary plate 6 and the inner cavity of the limit ring 3. A connecting rod 8 is fixedly connected to one side of the detection circular plate 4 and located on the upper and lower sides of the auxiliary plate 6. An inclined plate 9 is fixedly connected to the end of the connecting rod 8 away from the detection circular plate 4, and a docking plate 10 is fixedly connected to one side of the inclined plate 9. The ring formed by the two groups of docking plates 10 is larger than the ring formed by the two groups of detection circular plates 4.

[0031] The circular ring formed by the two groups of docking plates 10 in the initial state is larger than the diameter of the two groups of detection circular plates 4, which facilitates the entry of the optical fiber cable into the docking plate 10. After the optical fiber cable enters the docking plate 10, it slides into the detection circular plate 4 through the inclined surface of the inclined plate 9. The two groups of detection circular plates 4 in the initial state are in contact with each other, and the spring 7 is in a compressed state, generating elastic force to squeeze the two groups of detection circular plates 4. This is to make the inner side of the detection circular plate 4 fully fit with the surface of the optical fiber cable when the optical fiber cable enters the detection circular plate 4, so as to obtain more accurate diameter change data;

[0032] The middle of the first measuring ruler 5 is data 0, and the two sides are respectively a certificate and a negative number. The position where the first measuring ruler 5 contacts the surface of the limit ring 3 is used as the position for data reading. When the two sets of detection circular plates 4 are in contact with each other, the first measuring ruler 5 is a negative number. When the ring formed by the detection circular plates 4 is stretched by the normal optical fiber cable, the reading is 0. At this time, the change in the diameter of the optical fiber cable after stretching can be observed by comparing the data of the ring formed by the detection circular plates 4 stretched by the stretched optical fiber cable with the reading when the normal optical fiber cable is stretched.

[0033] The stretched optical fiber cable is connected to the detection circular plate 4 through the circular ring formed by the two groups of docking plates 10. When the stretched optical fiber cable passes through the detection circular plate 4, the two groups of detection circular plates 4 are stretched open, and the first measuring ruler 5 is displaced at this time. The diameter of the stretched optical fiber cable is observed by the displacement of the first measuring ruler 5, and then compared with the diameter before stretching to detect the data of the optical fiber cable. In this way, the detection does not need to be done manually, and there will be no measurement errors caused by hand shaking. The measurement can also be kept on the same horizontal plane, thereby improving the measurement accuracy.

[0034] Two groups of extrusion plates 11 for extruding and resetting the optical fiber cable are arranged at the top of the bottom plate 1 and on one side of the limiting ring 3. The two groups of extrusion plates 11 are semicircular, and the bottom of the extrusion plate 11 is fixedly connected to a vertical plate 12, and the bottom of the vertical plate 12 is fixedly connected to two groups of sliders 13. A slide groove 14 is provided at the top of the bottom plate 1 and below the vertical plate 12. The inner cavity of the slide groove 14 is slidably connected to the surface of the slider 13, and the bottom of the vertical plate 12 contacts the top of the bottom plate 1. A fixed plate 15 is fixedly connected to the top of the bottom plate 1 and on one side of the vertical plate 12. A hydraulic cylinder 16 is fixedly connected to the fixed plate 15, and a top plate 17 is fixedly connected to the telescopic end of the hydraulic cylinder 16. The curvature of the surface of the top plate 17 is the same as that of the surface of the extrusion plate 11.

[0035] Before measuring the diameter of the optical fiber cable, the optical fiber cable is placed between two sets of extrusion plates 11, and the top plate 17 is driven to move by the extension of the hydraulic cylinder 16. The movement of the top plate 17 causes the extrusion plate 11 to exert pressure on the optical fiber cable, which can flatten the bent or convex optical fiber cable and keep the optical fiber cable in a cylindrical shape, so as to facilitate the subsequent measurement of the diameter and obtain more accurate measurement data.

[0036] A first vertical rod 25 is fixedly connected to the top of one group of extrusion plates 11, and a second measuring ruler 26 is fixedly connected to one side of the first vertical rod 25. A second vertical rod 27 is fixedly connected to the top of another group of extrusion plates 11, and a sleeve ring 28 is fixedly connected to the top of the second vertical rod 27. One end of the second measuring ruler 26 passes through the inner cavity of the sleeve ring 28.

[0037] The second measuring ruler 26 can record the initial diameter of the optical fiber cable after the squeezing of the squeezing plate 11 is completed. When the optical fiber cable enters the detection circular plate 4 through the pushing device, the spring 7 squeezes the detection circular plate 4 to make the detection circular plate 4 shrink inward. At this time, the squeezing plate 11 also moves with the rotation of the gear 22. The movement of the squeezing plate 11 drives the second measuring ruler 26 to move, thereby obtaining new data, and then comparing the data detected by the detection circular plate 4, and comparing with each other to obtain more accurate data.

[0038] A mounting rod 18 is fixedly connected to the surface of the extrusion plate 11, a first connecting rod 19 is fixedly connected to one side of the mounting rod 18, a first tooth plate 20 is fixedly connected to one end of the first connecting rod 19, a rotating rod 21 is rotatably connected to the top of the bottom plate 1, a gear 22 is fixedly connected to the top of the rotating rod 21, and the surface of the gear 22 meshes with the surface of the first tooth plate 20, a second connecting rod 23 is fixedly connected to one side of the docking plate 10, a second connecting rod 23 is fixedly connected to one end of the second connecting rod 23, and a second tooth plate 24 is fixedly connected to the surface of the gear 22.

[0039] First, the stretched optical fiber cable is reset before measurement. The initial position of the two sets of squeezing plates 11 used for reset is larger than the diameter of the optical fiber cable, which is convenient for inserting the optical fiber cable. After the optical fiber cable is placed between the two sets of squeezing plates 11, the optical fiber cable is pushed by the pushing device. When the optical fiber cable is reset and is to be measured in the docking plate 10, the end of the optical fiber cable is not supported and is easy to sag and may not be able to enter the docking plate 10 well.

[0040] When the two groups of extrusion plates 11 squeeze the stretched optical fiber cable, the extrusion plates 11 move inward, thereby driving the first connecting rod 19 to move, the movement of the first connecting rod 19 drives the first tooth plate 20 to move, the movement of the first tooth plate 20 drives the gear 22 to rotate, the rotation of the gear 22 drives the second tooth plate 24 to move, the second tooth plate 24 moves the second connecting rod 23 to move outward, the outward movement of the second connecting rod 23 drives the two groups of docking plates 10 to move outward at the same time, thereby expanding the diameter formed by the two groups of docking plates 10, and the docking plates 10 have a larger range to dock the optical fiber cables, so that the optical fiber cables can enter the docking plates 10 more smoothly.

[0041] Working principle: first reset the stretched optical fiber cable before measuring it. Before measuring the diameter of the optical fiber cable, put the optical fiber cable between the two groups of squeezing plates 11, and extend the hydraulic cylinder 16 to drive the top plate 17 to move. The movement of the top plate 17 causes the squeezing plate 11 to exert pressure on the optical fiber cable, which can flatten the bent or convex optical fiber cable. When the two groups of squeezing plates 11 squeeze the stretched optical fiber cable, the squeezing plate 11 moves inward, thereby driving the first connecting rod 19 to move. The movement of the first connecting rod 19 drives the first tooth plate 20 to move. The movement of the first tooth plate 20 drives the gear 22 to rotate. The rotation of the gear 22 drives the second tooth plate 24 to move. The second tooth plate 24 moves the second connecting rod 23 outward. The outward movement of the second connecting rod 23 drives the two groups of docking plates 10 to move outward at the same time, thereby expanding the diameter formed by the two groups of docking plates 10. At this time, the optical fiber cable is pushed into the docking plate 10 by the pushing device, and then slides into the detection circular plate 4 through the inclined surface of the inclined plate 9. After stretching When the optical fiber cable passes through the detection circular plate 4, the two groups of detection circular plates 4 are stretched open, and the first measuring ruler 5 is displaced at this time. The diameter of the stretched optical fiber cable is observed by the displacement of the first measuring ruler 5. At the same time, the extrusion plate 11 is also displaced with the rotation of the gear 22. The movement of the extrusion plate 11 drives the second measuring ruler 26 to move. The movement of the second measuring ruler 26 will change the measured diameter value. As mentioned above, after the detection circular plate 4 moves, the extrusion plate 11 is correspondingly displaced, and the two groups of displacement distances are the same. Therefore, the difference between the diameter value obtained after the second measuring ruler 26 moves and the diameter value before the second measuring ruler 26 moves should be the same as the difference between the values ​​before and after the detection of the first measuring ruler 5. At this time, the difference between the values ​​before and after the measurement of the first measuring ruler 5 and the second measuring ruler 26 is observed. If the values ​​are the same, it means that the detection of the detection circular plate 4 is accurate. If the values ​​are different, it means that there is an error in the detection of the detection circular plate 4, which confirms the accuracy of the detection of the detection circular plate 4 and compares them with each other.
