Description

Technical Field

[0001] This utility model relates to the field of filler rope testing technology, specifically a device for testing the tensile strength of optical cable filler rope. Background Technology

[0002] Optical cable filler rope is a material used to fill the core tube of optical cables, and its function is to enhance the physical strength of the optical cable. During production, to ensure its quality, the optical cable filler rope needs to undergo tensile testing using a tensile testing device.

[0003] As described in the Chinese patent application CN202022680786.X, a testing device for cable filler ropes states: "A testing platform is provided on one side of its upper end, the clamping mechanism includes a clamping block, the top of the clamping block has an array of slots, the filler rope body is detachably disposed in the slots, the upper end of the clamping block has a U-shaped frame, the upper end of the U-shaped frame has a cylinder, the output end of the cylinder passes through the U-shaped frame and has a clamping plate at its end, the clamping plate is slidably locked inside the U-shaped frame. This utility model has a simple structure and reasonable design. Under the coordinated action of the clamping mechanism, pulleys, counterweight components and counterweight blocks, it provides convenience for testing the tensile strength of the filler rope body, thereby improving the user's work efficiency. Through the combined use of multiple sets of slots and pulleys, it provides convenience for testing the combined tensile strength of multiple sets of filler rope bodies, thereby improving the practicality of the testing device."

[0004] By searching the aforementioned patents and combining them with existing technologies, we found certain shortcomings in this type of technology after simulated use:

[0005] Since optical fiber filler ropes are typically rolled up on rollers after production, the current technology for tensile testing involves cutting a certain length of filler rope from the roller. This method can only test a section of filler rope near the end. To ensure that the tensile strength of filler ropes at different lengths throughout the roll is up to standard, it may be necessary to test filler ropes at different lengths. If this is required, the current technology usually involves cutting a section of filler rope (cutting at different lengths throughout the roll) for testing. This damages the integrity of the entire roll of filler ropes and results in waste. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a device for testing the tensile strength of optical cable filler rope, comprising a fixed base, a clamping platform one and a clamping platform two driven by a servo motor one fixed on the top of the fixed base, both clamping platforms one and two being provided with cylinders, through holes and pressure plates; a protective frame covering the outside of clamping platforms one and two fixed on the top of the fixed base, with an inlet hole on one side of the protective frame and an outlet hole on the other side; two support frames one fixed on the top of the fixed base and on the side of the inlet hole, with a conveying roller with optical cable filler rope wound on its surface arranged between the two support frames one; and two support frames two fixed on the top of the fixed base and on the side of the outlet hole, with a winding roller arranged between the two support frames two.

[0008] As a further embodiment of this utility model: there are two cylinders, and the two cylinders are respectively installed on the top of clamping platform one and clamping platform two. There are two through holes, which are respectively opened on the side of clamping platform one and clamping platform two. There are two pressure plates, which are respectively slidably connected in the two through holes. The power output shaft of the cylinder moves through the through hole and is fixedly connected to the pressure plate. Rubber strips are fixed at equal intervals on the bottom of the pressure plate and the inner bottom wall of the through hole.

[0009] As a further embodiment of this utility model: a guide groove is provided at the top of the fixed base and at the bottom of the clamping platform two. A guide slider is fixed at the bottom of the clamping platform two and slidably connected in the guide groove. The servo motor one is installed on one side of the fixed base and at a position corresponding to the guide groove. The power output shaft of the servo motor one moves through the guide groove and is connected to a lead screw one. The end of the lead screw one away from the servo motor one is threaded through the guide slider and rotatably connected to the inner wall of one side of the guide groove.

[0010] As a further embodiment of this utility model: scale lines are provided on the top of the fixed base and on both the front and rear sides of the clamping platform.

[0011] As a further embodiment of this utility model: the inlet hole, the through hole on clamping platform one, the through hole on clamping platform two, and the outlet hole are all on the same horizontal line.

[0012] As a further embodiment of this utility model: the top of the protective frame is an open structure, and a closing cover for covering the top of the protective frame is hinged to the opening at the top of the protective frame. Both the protective frame and the closing cover are made of transparent acrylic material.

[0013] As a further embodiment of this utility model: a limiting groove is provided at the top of the fixed base and at the position between clamping platform one and clamping platform two. A limiting slider driven by servo motor two is slidably connected in the limiting groove. Two cylindrical actuating rods are fixed at the top of the limiting slider and the two actuating rods are far apart from each other.

[0014] As a further embodiment of this utility model: the second servo motor is installed on one side of the fixed base and at a position corresponding to the limiting slide groove. The power output shaft of the second servo motor moves through the limiting slide groove and is connected to the second lead screw. The end of the second lead screw away from the second servo motor is threaded through the limiting slider and rotatably connected to one side of the inner wall of the limiting slide groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] I. In this application, through the designed fixed base, conveying roller, winding roller, clamping table one and clamping table two, tensile strength testing of the complete length of optical cable filler rope can be performed. The tensile strength testing of the optical cable filler rope is achieved by moving clamping table two, so as to detect whether the optical cable filler rope of that length is qualified. Moreover, the optical cable filler rope does not need to be cut during the testing process, which can ensure the integrity of the entire roll of optical cable filler rope. If the test is qualified, it can be used directly in the future, avoiding waste.

[0017] Second, in this application, through the designed servo motor, limit slider, and toggle rod, the optical cable filler rope can be moved back and forth during the optical cable filler rope testing process to simulate the swinging and other conditions experienced by the optical cable filler rope during use. By moving the optical cable filler rope during the tensile test, compared with the current technology which only performs simple tensile tests, it is more able to simulate the actual use of the optical cable filler rope and improve the accuracy of the test results.

[0018] Third, in this application, by designing a protective frame or other structure on the fixed base, clamping platform one and clamping platform two can be covered, so that the optical cable filling rope is tested inside the protective frame, avoiding the rebound caused by the optical cable filling rope breaking during testing and preventing injury to nearby personnel, thus improving the safety during testing.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0027] Please see Figure 1-5 A device for testing the tensile strength of optical cable filler rope includes a fixed base 1. A clamping platform 4 and a clamping platform 5 driven by a servo motor 7 are fixed to the top of the fixed base 1. Both clamping platforms 4 and 5 are equipped with cylinders 14, through holes 13, and pressure plates 15. A protective frame 6 is fixed to the top of the fixed base 1, covering the outside of the clamping platforms 4 and 5. One side of the protective frame 6 has an inlet hole 601 for the optical cable filler rope to enter the protective frame 6, and the other side of the protective frame 6 has an outlet hole 602 for the optical cable filler rope. The filler rope passes through the protective frame 6; two support frames 1 2 are fixed on the top of the fixed base 1 and on one side of the inlet hole 601. A conveyor roller 201 with the optical cable filler rope wound on its surface is arranged between the two support frames 1 2. The conveyor roller 201 is used to convey the wound optical cable filler rope for easy testing. Two support frames 2 3 are fixed on the top of the fixed base 1 and on one side of the outlet hole 602. A take-up roller 301 is arranged between the two support frames 2 3. The take-up roller 301 is used to take up the optical cable filler rope after testing. This process avoids cutting the optical cable filler rope and avoids waste.

[0028] Please see Figure 1 and Figure 2 In this embodiment, there are two cylinders 14, which are respectively installed on the top of clamping platform 1 4 and clamping platform 2 5. There are two through holes 13, which are respectively opened on the side of clamping platform 1 4 and clamping platform 2 5. There are two pressure plates 15, which are slidably connected in the two through holes 13. The power output shaft of the cylinder 14 moves through the through hole 13 and is fixedly connected to the pressure plate 15. Rubber strips 16 are fixed at equal intervals on the bottom of the pressure plate 15 and the inner bottom wall of the through hole 13.

[0029] Specifically, after the cylinder 14 is started, it can drive the pressure plate 15 placed in the perforation 13, thereby making it move. When the bottom of the pressure plate 15 contacts the optical cable filling rope, it can press the optical cable filling rope tightly against the inner bottom wall of the perforation 13. In conjunction with the rubber strip 16, it can increase the friction during pressing and improve stability.

[0030] Please see Figure 1 and Figure 2 In this embodiment, a guide groove 8 is provided at the top of the fixed base 1 and at the bottom of the clamping platform 2 5. A guide slider 9 is fixed at the bottom of the clamping platform 2 5 and slidably connected in the guide groove 8. A servo motor 1 7 is installed on one side of the fixed base 1 and at a position corresponding to the guide groove 8. The power output shaft of the servo motor 1 7 moves through the guide groove 8 and is connected to a lead screw 1 701. The end of the lead screw 1 701 away from the servo motor 1 7 is threaded through the guide slider 9 and rotatably connected to the inner wall of one side of the guide groove 8.

[0031] Specifically, after the servo motor 7 starts, it can drive the lead screw 701 to rotate in both directions, thereby driving the guide slider 9 and the clamping platform 5 to reciprocate. When the clamping platform 5 moves to the side closer to the outlet hole 602, it can perform a pull test on the optical cable filling rope. Conversely, it can loosen the optical cable filling rope to facilitate the passage of the optical cable filling rope.

[0032] Please see Figure 1 In this embodiment, scale lines are provided on the top of the fixed base 1 and on both the front and rear sides of the clamping platform 2 5.

[0033] Specifically, the scale lines can be used as a reference for the movement distance of clamping platform 25, so as to intuitively observe the movement distance of clamping platform 25. When clamping platform 25 moves to a specific scale (this specific scale can be determined in advance by the movement distance of the qualified optical cable filler rope, i.e., clamping platform 25), the qualification of the optical cable filler rope can be intuitively judged by whether the optical cable filler rope is broken.

[0034] Please see Figure 1 and Figure 4In this embodiment, the inlet hole 601, the through hole 13 on the clamping platform 4, the through hole 13 on the clamping platform 5, and the outlet hole 602 are on the same horizontal line.

[0035] Specifically, multiple holes are on the same horizontal line, which facilitates the passage of the fiber optic cable filler rope and ensures the straightness of the fiber optic cable filler rope.

[0036] Please see Figure 1 , Figure 4 and Figure 5 In this embodiment, the top of the protective frame 6 is an open structure, and a sealing cover 603 for covering the top of the protective frame 6 is hinged to the opening at the top of the protective frame 6. Both the protective frame 6 and the sealing cover 603 are made of transparent acrylic material.

[0037] Specifically, the protective frame 6 can form a protective structure on the fixed base 1 to prevent the optical cable filler rope from breaking during testing and causing injury to nearby personnel. At the same time, the protective frame 6 is transparent, allowing personnel to easily observe the inside of the protective frame 6. The sealing cover 603 is used to cover the top of the protective frame 6 to improve the protective effect. When setting the optical cable filler rope, it can be opened and closed after setting, making the operation convenient.

[0038] Please see Figure 1 and Figure 3 In this embodiment, a limiting groove 10 is provided at the top of the fixed base 1, located between the clamping platform 4 and the clamping platform 5. A limiting slider 12 driven by a servo motor 11 is slidably connected in the limiting groove 10. Two cylindrical actuating rods 17 are fixed at the top of the limiting slider 12, and the two actuating rods 17 are far apart from each other. The servo motor 11 is installed on one side of the fixed base 1 at a position corresponding to the limiting groove 10. The power output shaft of the servo motor 11 moves through the limiting groove 10 and is connected to a lead screw 1101. The end of the lead screw 1101 away from the servo motor 11 is threaded through the limiting slider 12 and rotatably connected to one side of the inner wall of the limiting groove 10.

[0039] Specifically, by starting the servo motor 11, the lead screw 1101 can be driven to rotate in both directions, thereby causing the limit slider 12 to move back and forth in the limit groove 10. This allows the two levers 17 to move the optical cable filling rope placed between them back and forth, simulating the swinging situation after being straightened in actual use, thus improving the detection effect.

[0040] When using:

[0041] The end of the optical cable filler rope is pulled from the conveyor roller 201, passing sequentially through the inlet hole 601, the through hole 13 on clamping platform 4, between the two actuating rods 17, the through hole 13 on clamping platform 5, and the outlet hole 602, and then bound to the take-up roller 301. The sealing cover 603 is then closed. Next, the cylinders 14 on clamping platforms 4 and 5 are activated. The power output shaft of cylinder 14 pushes the pressure plate 15 downward, thereby compressing the optical cable filler rope placed in the through hole 13, fixing the section of the optical cable filler rope between clamping platforms 4 and 5. Then, servo motor 7 is activated. The power output shaft of servo motor 7 drives the lead screw 701 to rotate, driving the guide slide... Block 9 moves, causing clamping platform 2 5 to slowly move towards the outlet hole 602. When clamping platform 2 5 moves, the optical cable filling rope can be pulled to test its tensile strength. When clamping platform 2 5 moves, the staff can refer to the scale lines to determine the movement distance of clamping platform 2 5. For example, the qualified tensile strength of optical cable filling rope is when clamping platform 2 5 moves from the 0CM scale to the 5CM scale. When clamping platform 2 5 reaches the 5CM scale, the optical cable filling rope does not break and is judged as qualified. When clamping platform 2 5 does not reach the 5CM scale, the optical cable filling rope breaks and is judged as unqualified. This method is more intuitive and can clearly provide feedback to the staff.

[0042] After the fiber optic cable filler rope is tested, the servo motor 7 can be started to return the clamping table 5 to its initial position and the cylinder 14 can be used to release the clamp on the fiber optic cable filler rope. Then the take-up roller 301 can be rotated to take the tested fiber optic cable filler rope onto the take-up roller 301. After that, the fiber optic cable filler ropes of different lengths on the roller can be placed back between the clamping table 4 and the clamping table 5 by the unwinding of the conveying roller 201 and clamped for testing. This process does not require cutting the fiber optic cable filler rope.

[0043] If the fiber optic cable filler rope breaks during testing, the broken end can be re-tied to the take-up roller 301 to test the subsequent length of the fiber optic cable filler rope. If it breaks multiple times, the roll of fiber optic cable filler rope can be determined to be a defective product.

[0044] Alternatively, it may not be necessary to inspect the entire roll of optical cable filler rope. After inspecting multiple sections of optical cable filler rope on the conveyor roller 201, none of them show any breakage. The inspected optical cable filler rope can be rewound using the conveyor roller 201, making it convenient for the optical cable filler rope wound on the conveyor roller 201 to be used in subsequent production. Alternatively, the entire roll of optical cable filler rope can be inspected, depending on the actual situation. When inspecting the entire roll of optical cable filler rope, the entire length of optical cable filler rope will be sent to the conveyor roller 201 and transferred to the take-up roller 301.

[0045] When the fiber optic cable filler rope is pulled, the servo motor 2 11 can be activated. The power output shaft of the servo motor 2 11 drives the limit slider 12 to slide in the limit groove 10, thereby driving the two toggle rods 17 to move on both sides of the fiber optic cable filler rope to simulate the swinging situation that the fiber optic cable filler rope is subjected to after being straightened in actual use.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
