Description

Technical Field

[0001] This invention belongs to the field of steel-plastic composite tape testing technology, specifically relating to a strength testing device for steel-plastic composite tape used in optical cables. Background Technology

[0002] Steel-plastic composite tape is a composite product made of special micro high-strength galvanized iron wire and wrapped with anti-aging and acid-alkali resistant polyethylene resin. It is a combination of rigid and flexible materials. It is also called steel-plastic composite reinforcing tape. Its main load-bearing element is steel wire, and its creep is very small. It is generally installed on the outside of communication cables to protect them.

[0003] Because steel-plastic composite tape is prone to breakage during transportation, the quality of the finished optical cable may be affected if strength testing is not performed. Therefore, when the steel-plastic composite tape is wrapped around the surface of the optical cable, tensile strength and bending strength tests are required. Existing strength testing equipment can only perform single tensile or bending tests. When conducting other tests, the steel-plastic composite tape needs to be repeatedly disassembled and reassembled from the test platform, which greatly increases the workload, wastes testing time, affects testing efficiency, and cannot ensure testing accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a strength testing device for steel-plastic composite tape for optical cables. This device can perform different tests without disassembling the steel-plastic composite tape, effectively testing its tensile and bending strength. It can also reduce the need for repeated disassembly and installation, thus improving testing efficiency.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A strength testing device for steel-plastic composite tape for optical cables includes a support platform, a support frame fixed to the top of the support platform, and a control box fixed to the top of the support frame.

[0007] The testing mechanism includes a testing platform and a drive push rod. The testing platform is fixed to the top of the support platform. A sliding groove is provided on the testing platform, and a support plate is fixed in the sliding groove. A pneumatic rod is fixed to one side of the support plate. The output shaft of the pneumatic rod is fixedly connected to one side of the testing plate. The testing plate is slidably connected inside the sliding groove. The drive push rod is fixed inside the control box, and a connector is fixed to the output shaft of the drive push rod.

[0008] A fixing mechanism includes a connecting plate, a connecting shaft fixed to one end of the connecting plate, and rotating cylinders rotatably connected to the inside of both sides of the connecting plate. The rotating cylinders are threaded to one end of a plurality of fixing rods, and the other ends of the plurality of fixing rods are fixedly connected to the fixing plate. Anti-slip pads are fixed to the side of the connecting plate adjacent to the fixing plate.

[0009] The fixing mechanism is connected to the support plate, the test plate and the connector via the connecting shaft. The drive push rod drives the connector to apply a strength test force to the steel-plastic composite belt, thereby causing the test plate to interact with the support plate, effectively testing the tensile strength and flexibility of the steel-plastic composite belt.

[0010] Furthermore, the support plate has a mounting hole at one end away from the sliding groove, and the mounting hole is detachably connected to the connecting shaft.

[0011] Furthermore, a fixing hole is provided at the end of the test plate away from the sliding groove, and the fixing hole is detachably connected to the connecting shaft.

[0012] Furthermore, a limiting hole is also provided on the end of the test plate away from the sliding groove. The limiting hole is located inside the fixing hole and is a through hole.

[0013] Furthermore, a limiting push rod is fixed inside the end of the test platform away from the support plate. The output shaft of the limiting push rod passes through the limiting hole, and the output shaft of the limiting push rod is slidably connected to the upper part of the sliding groove.

[0014] Furthermore, the connector has a mounting groove at its bottom, which is detachably connected to the connecting shaft.

[0015] The technical effects achieved by this utility model are as follows:

[0016] This utility model discloses a strength testing device for steel-plastic composite tape used in optical cables. A fixing mechanism secures the steel-plastic composite tape, ensuring it does not slip or shift during testing, thus improving test accuracy. In conjunction with the testing mechanism, when a limiting push rod inside the testing platform limits the test plate, it fixes the test plate inside the testing platform and engages with the support plate. When the driving push rod applies a test force to the steel-plastic composite tape through the connector, the tensile strength of the steel-plastic composite tape can be effectively measured, thereby improving the reliability and service life of the optical cable.

[0017] This utility model discloses a strength testing device for steel-plastic composite tape for optical cables. By controlling the limiting push rod inside the test bench to release the limiting of the test plate, when a test force is applied to the steel-plastic composite tape, the test plate can slide inside the test bench and cooperate with the support plate. This ensures that the product does not need to be disassembled, reducing the steps of repeated disassembly and installation, and can complete the tensile strength and bending strength tests of the steel-plastic composite tape, shortening the test time and improving the test efficiency.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figures 1 to 5 As shown, a strength testing device for steel-plastic composite tape for optical cables includes a support platform 10, a support frame 11 fixed on the top of the support platform 10, and a control box 12 fixed on the top of the support frame 11.

[0027] The testing mechanism 20 includes a testing platform 21 and a drive push rod 22. The testing platform 21 is fixed to the top of the support platform 10. A sliding groove 211 is provided on the top of the testing platform 21. A support plate 23 is fixed inside the sliding groove 211. A pneumatic rod 24 is fixed on one side of the support plate 23. The output shaft of the pneumatic rod 24 is fixedly connected to one side of the testing plate 25. The testing plate 25 is slidably connected to the inside of the sliding groove 211. The drive push rod 22 is fixed inside the control box 12, and a connector 26 is fixed to the output shaft of the drive push rod 22. The connector 26 is located above the testing platform 21.

[0028] The fixing mechanism 30 includes a connecting plate 31. One end of the connecting plate 31 is fixed with a connecting shaft 311, and both sides of the connecting plate 31 are rotatably connected with rotating cylinders 32. The interior of the rotating cylinders 32 is threadedly connected to one end of a plurality of fixing rods 33. The other ends of the plurality of fixing rods 33 are fixedly connected to a fixing plate 34. Anti-slip pads are fixed on the side of the connecting plate 31 adjacent to the fixing plate 34.

[0029] The fixing mechanism 30 is fixedly connected to the support plate 23, the test plate 25 and the connector 26 respectively through the connecting shaft 311. The drive push rod 22 drives the connector 26 to apply a strength test force to the steel-plastic composite belt, thereby causing the test plate 25 to act on the support plate 23, effectively detecting the tensile and flexibility properties of the steel-plastic composite belt.

[0030] In this embodiment, it should be noted that a display screen and multiple control buttons are fixedly installed on the outside of the control box 12, and the control box 12 is electrically connected to the drive push rod 22, which can effectively control the test force generated by the drive push rod 22, thereby effectively testing the tensile strength and bending strength of the steel-plastic composite strip; by placing the steel-plastic composite strip in the fixing mechanism 30, by controlling the rotating cylinders 32 on both sides of the connecting plate 31 respectively, the rotating cylinders 32 and the fixing rod 33 are driven by the thread action of the threaded action of the threaded action of the threaded cylinders 32 and the fixing rod 33 to move the fixing plate 34 fixedly connected to the fixing rod 33 closer to the connecting plate 31, and the steel-plastic composite strip is squeezed and fixed by the connecting plate 31 and the fixing plate 34; at the same time, the fixing plate 34 and the connecting plate 31 are used to fix the steel-plastic composite strip. The anti-slip pads on plate 31 effectively prevent the steel-plastic composite belt from moving during testing, ensuring the stability and safety of the steel-plastic composite belt. It should be noted that the side of the connecting plate 31 adjacent to the fixing plate 34 can be set according to the shape of the steel-plastic composite belt, which can effectively ensure the stability and fit during fixing. After fixing is completed, the drive push rod 22 is controlled to drive the fixing mechanism 30 to rise and fall through the connector 26. During the rising and falling process, a test force is applied to the steel-plastic composite belt. Since the support plate 23 is fixedly connected to the test table 21, the test plate 25 is driven to slide in the sliding groove 211 to complete the bending strength test of the steel-plastic composite belt.

[0031] Preferably, the end of the support plate 23 away from the sliding groove 211 is provided with a mounting hole. By detachably connecting the mounting hole to the connecting shaft 311, the connecting plate 31 can be effectively fixed on the support plate 23, thus completing the fixing mechanism 30 to fix the steel-plastic composite belt.

[0032] like Figure 3 , Figure 5 As shown, a fixing hole 251 is provided at the end of the test plate 25 away from the sliding groove 211. By detachably connecting the connecting shaft 311 to the fixing hole 251, the stability when connected to the fixing mechanism 30 can be ensured, thus ensuring the safety of the test.

[0033] Preferably, a limiting hole 252 is also provided on the end of the test plate 25 away from the sliding groove 211. The limiting hole 252 is located inside the fixing hole 251 and is a through hole. By providing the limiting hole 252, the test plate 25 can be fixed to ensure that the device can effectively perform tensile strength testing on the steel-plastic composite strip.

[0034] like Figure 4 As shown, a limit push rod 212 is fixed inside the end of the test platform 21 away from the support plate 23. The output shaft of the limit push rod 212 passes through the limit hole 252, and the output shaft of the limit push rod 212 is slidably connected to the upper part of the sliding groove 211.

[0035] In this embodiment, the steel-plastic composite strip is fixed to the support plate 23, the test plate 25, and the connector 26 using the fixing mechanism 30. Then, the limiting push rod 212 is controlled so that its output shaft passes through the limiting hole 252 and slides to connect with the hole opened above the sliding groove 211, thereby completing the limiting and fixing of the test plate 25. When the drive push rod 22 drives the connector 26 to apply a test force to the steel-plastic composite strip, at this time, the two ends of the steel-plastic composite strip are fixedly connected by the support plate 23 and the test plate 25 respectively. When tension or pressure is applied to the steel-plastic composite strip, it is possible to effectively observe whether the steel-plastic composite strip deforms, thereby completing the tensile strength test of the steel-plastic composite strip. After the tensile strength test is completed, the output shaft is retracted by controlling the limiting push rod 212 so that it does not limit the test plate 25. Then, the drive push rod 22 is restarted to drive the connector 26 to apply a test force to the steel-plastic composite strip, thereby completing the bending strength test.

[0036] Preferably, the bottom of the connector 26 is provided with a mounting groove, and a connecting shaft 311 is fixed inside the mounting groove; wherein, by opening the mounting groove, it can be effectively connected with the fixing mechanism 30, ensuring that the test force can be accurately applied to the steel-plastic composite strip during testing, and ensuring the stability of the strength test.

[0037] The working principle of this utility model is as follows: When strength testing of a steel-plastic composite strip is required, multiple fixing mechanisms 30 are sequentially installed on the support plate 23, the test plate 25, and the connector 26. Then, the rotating cylinder 32 inside the rotating connecting plate 31 is controlled to engage with the fixing rod 33 via a threaded action, thereby driving the fixing plate 34 and the connecting plate 31 to compress and fix the steel-plastic composite strip. After fixing is completed, the limiting push rod 212 inside the test bench 21 is controlled to limit the output shaft of the test plate 25 by engaging the limiting hole 252 on the test plate 25, thereby fixing the test plate 25 and preventing it from moving in the sliding groove 211. Subsequently, by activating the drive push rod 22, the fixing mechanism 30 on the connector 26 is driven to apply a test force to the steel-plastic composite strip, effectively testing the steel-plastic composite strip. The tensile strength of the composite strip; after the tensile test is completed, the output shaft is driven by the control limit push rod 212 to release the limit on the test plate 25, and the drive push rod 22 is started again. Since the support plate 23 is fixedly connected to the sliding groove 211 in the test table 21, and the test plate 25 is slidably connected to the sliding groove 211 at this time, when the connector 26 applies a test force to the steel-plastic composite strip through the fixing mechanism 30, it can drive the steel-plastic composite strip to bend and deform, thereby driving the test plate 25 to move in the sliding groove 211 and compressing and energizing the pneumatic rod 24. When it rises to the designated position, the connector 26 is controlled to descend. At this time, the pneumatic rod 24 is no longer compressed, and the air pressure is released, thereby driving the test plate 25 to reset. Through multiple bending tests, the bending strength of the steel-plastic composite strip can be effectively tested.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
