Description

Technical Field

[0001] This utility model relates to the technical field of cable performance testing equipment, and in particular to a testing device for testing the breaking strength of cables. Background Technology

[0002] As a core carrier of energy transmission and information delivery, cables are widely used in key areas such as power systems, communication networks, and urban rail transit. The tensile strength of their outer sheath and insulation directly determines their service life and operational safety. During cable laying, cables must withstand external forces such as soil compression and mechanical impact; in long-term operation, they are also affected by environmental aging and temperature changes. If the tensile strength is insufficient, problems such as sheath damage and insulation failure can easily occur, leading to safety accidents such as short circuits, leakage, and even fires. Therefore, accurate testing of cable tensile strength is a crucial link in ensuring the stable operation of cable systems.

[0003] Existing technical solutions are difficult to use because the cables are often bent and difficult to place flat on top of the test object. This can easily cause the cables to shift during the test, affecting the accuracy of the test data.

[0004] To address the above problems, this utility model provides a testing device for detecting the breaking strength of cables. Utility Model Content

[0005] The purpose of this invention is to solve the problems of poor cable fixing effect and easy cable deviation during the testing process in the existing technology, which affects the accuracy of the test data, and to propose a test device for testing the breaking strength of cables.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a testing device for detecting the breaking strength of cables, comprising a stable base plate, a test positioning mechanism, and a control printing mechanism, wherein the test positioning mechanism and the control printing mechanism are fixedly connected to the top of the stable base plate, the control printing mechanism is fixedly connected to one side of the top of the stable base plate, and the test positioning mechanism includes a support frame fixedly connected to the other side of the top of the stable base plate.

[0007] The test positioning mechanism includes a positioning component and a test component. The positioning component includes a positioning clamping plate, and the test component includes a pressure plate.

[0008] The positioning component is fixedly connected to the other side of the top of the stable base plate. The positioning component includes a test object placement block fixedly connected to the top of the stable base plate. A pressure sensor is fixedly connected inside the test object placement block. A limit plate is fixedly connected to the outer surface of the test object placement block. An adjuster is threadedly connected to the top of the limit plate. A bearing is rotatably connected to the bottom of the adjuster. The outer surface of the bearing is fitted into the interior of the positioning clamping plate.

[0009] Furthermore, the positioning clamping plate is rotatably connected to the bottom of the adjuster via a bearing, and the limiting plate and the positioning clamping plate are set at a distance of four equal parts on the outer surface of the test object placement block.

[0010] Furthermore, the test assembly includes a rotating threaded ring fixedly connected inside the support frame, a rotating threaded rod rotatably connected inside the rotating threaded ring, and a connecting disc rotatably connected to the bottom of the rotating threaded rod.

[0011] Furthermore, the bottom of the connecting plate is fixedly connected to a threaded connection port, the clamping plate is threadedly connected to the outer surface of the threaded connection port, the bottom of the clamping plate is fixedly connected to a test pressing block, and the top of the rotating threaded rod is fixedly connected to a manual crank wheel.

[0012] Furthermore, a pressure gauge is fixedly connected to the top of the support frame, and data connection lines are fixedly connected to both sides of the support frame.

[0013] Furthermore, the data connection line on one side of the support frame is fixedly connected to the outer surface of the pressure gauge, and the data connection line on the other side of the support frame is fixedly connected to the outer surface of the control printing mechanism.

[0015] Furthermore, a printing outlet is fixedly connected to the bottom of the control panel, a dust cover is snapped onto the outer surface of the printing outlet, and a power switch is fixedly connected to the outer surface of the control panel.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, the precise positioning and stable detection of the cable are achieved through the setup of a positioning clamping plate, a pressure sensor, and a clamping plate. The four-way synchronous positioning clamping structure applies clamping force evenly from all sides of the cable, ensuring that the cable does not shift during the detection process, thus solving the problem of poor positioning stability in existing equipment. The use of a high-precision threaded transmission combined with a manual crank wheel enables precise fine-tuning of the pressure, and the thread self-locking function prevents pressure deviation. At the same time, the high-precision pressure sensor and digital pressure gauge can accurately collect and display pressure data in real time, making it easy to capture the critical pressure value at the moment of cable rupture and improving the accuracy of the experiment.

[0019] Please see Figure 1-6This utility model provides a technical solution: a test device for detecting the breaking strength of cables, including a stable base plate 1, a test positioning mechanism 2 and a control printing mechanism 3. The test positioning mechanism 2 and the control printing mechanism 3 are fixedly connected to the top of the stable base plate 1, and the control printing mechanism 3 is fixedly connected to one side of the top of the stable base plate 1. The test positioning mechanism 2 includes a support frame 21 fixedly connected to the other side of the top of the stable base plate 1.

[0020] The following section will explain the specific setup and function of its test positioning mechanism 2 and control printing mechanism 3.

[0021] In this implementation scheme: the test positioning mechanism 2 includes a positioning component 22 and a test component 23. The positioning component 22 includes a positioning clamping plate 221, and the test component 23 includes a pressure plate 231.

[0022] The positioning component 22 is fixedly connected to the other side of the top of the stable base plate 1. The positioning component 22 includes a test object placement block 222 fixedly connected to the top of the stable base plate 1. A pressure sensor 223 is fixedly connected inside the test object placement block 222. A limit plate 224 is fixedly connected to the outer surface of the test object placement block 222. An adjuster 225 is threadedly connected to the top of the limit plate 224. A bearing 226 is rotatably connected to the bottom of the adjuster 225. The outer surface of the bearing 226 is fitted into the interior of the positioning clamping plate 221.

[0023] The above components achieve the following effects: by rotating the adjuster 225, the positioning clamping plate 221 can be moved up and down with the help of the bearing 226 to clamp or release the test object. The four equally divided limiting plates 224 and the positioning clamping plate 221 can limit and fix the test object from four directions to ensure that the test object does not shift during the test. At the same time, the pressure sensor 223 can monitor the clamping pressure in real time to avoid damaging the test object by clamping too tightly or affecting the test stability by clamping too loosely.

[0024] Specifically, the positioning clamping plate 221 is rotatably connected to the bottom of the adjuster 225 via the bearing 226, and the limiting plate 224 and the positioning clamping plate 221 are set at a distance of four equal parts on the outer surface of the test object placement block 222.

[0025] The effect achieved by the above components is that the four equally divided limiting plates 224 and positioning clamping plates 221 can form uniform constraints in four directions around the cable, preventing the cable from radially shifting during the testing process, ensuring that the cable is always in the center position of the test object placement block 222, and ensuring the accuracy of pressure application.

[0026] Specifically, the test component 23 includes a rotating threaded ring 232 fixedly connected inside the support frame 21, a rotating threaded rod 233 rotatably connected inside the rotating threaded ring 232, and a connecting plate 234 rotatably connected to the bottom of the rotating threaded rod 233.

[0027] The effect achieved by the above components is as follows: the rotating threaded ring 232 provides stable support and rotation track for the rotating threaded rod 233. When the rotating threaded rod 233 rotates within the rotating threaded ring 232, it can move up and down axially, thereby driving the connecting plate 234 and the pressing plate 231 below to rise and fall synchronously. This facilitates the adjustment of the initial height of the pressing plate 231 according to the thickness of the test object, ensuring that the test pressing block 236 can accurately contact the test object.

[0028] Specifically, the bottom of the connecting plate 234 is fixedly connected to a threaded connection port 235, the clamping plate 231 is threadedly connected to the outer surface of the threaded connection port 235, the bottom of the clamping plate 231 is fixedly connected to a test pressing block 236, and the top of the rotating threaded rod 233 is fixedly connected to a manual crank wheel 237.

[0029] The effects achieved by the above components are as follows: the threaded connection port 235 enables the clamping plate 231 and the connecting plate 234 to be detachably connected, making it convenient to replace the clamping plate 231 with test pressing blocks 236 of different specifications according to different test requirements; the manual crank 237 increases the force application point of the operator, making the operation of rotating the threaded rod 233 less strenuous, and the pressure of the test pressing block 236 on the test object can be precisely controlled by rotating the manual crank 237 to meet the pressure requirements under different test scenarios.

[0030] Specifically, a pressure gauge 24 is fixedly connected to the top of the support frame 21, and data connection cables 25 are fixedly connected to both sides of the support frame 21.

[0031] The effect achieved by the above components is that the pressure gauge 24 can receive the pressure signal transmitted by the pressure sensor 223 through the data connection line 25, and display the real-time pressure value during the test in an intuitive way, so that the operator can monitor the pressure change.

[0032] Specifically, the data connection line 25 on one side of the support frame 21 is fixedly connected to the outer surface of the pressure gauge 24, and the data connection line 25 on the other side of the support frame 21 is fixedly connected to the outer surface of the control printing mechanism 3.

[0033] The aforementioned components achieve the following effect: the data connection cable 25 on the other side transmits the test data to the control printing mechanism 3, realizing centralized processing and storage of the test data, and providing support for subsequent data viewing and analysis.

[0034] Specifically, the control printing mechanism 3 includes a control panel 31 fixedly connected to the top of the stable base plate 1, and a display screen 32 fixedly connected to the top of the control panel 31.

[0035] The effects achieved by the above components are as follows: the control panel 31, as the core of the equipment operation, can realize functions such as setting test parameters and controlling the start and stop of the test process; the display screen 32 can display test data, pressure change curves, equipment operating status and other information in real time, allowing operators to intuitively understand the test progress and make timely adjustments to the operation.

[0036] Specifically, a printer outlet 33 is fixedly connected to the bottom of the control panel 31, a dust cover 34 is snapped onto the outer surface of the printer outlet 33, and a power switch 35 is fixedly connected to the outer surface of the control panel 31.

[0037] The effects achieved by the above components are as follows: the printout 33 can print out the test data stored in the control printing mechanism 3, which is convenient for paper record archiving; the dust cover 34 can cover the printout 33 when the equipment is not in use, preventing dust and debris from entering and affecting the printing function; and the power switch 35 is used to control the power supply of the entire equipment, ensuring that the equipment is disconnected from the power supply when not in operation, saving energy and improving equipment safety.

[0038] Working principle: When in use, first start the device by power switch 35, place the object to be tested on the test object placement block 222, rotate the adjuster 225 of the positioning component 22 so that the four sets of positioning clamping plates 221 move towards the test object synchronously and clamp under the action of bearing 226. At this time, the pressure sensor 223 detects the clamping pressure in real time to ensure that the pressure is within a reasonable range and transmits the signal to the control panel 31 through the data connection cable 25.

[0039] The operator sets the test parameters through the control panel 31, and the parameter information is displayed on the display screen 32. Then, the operator rotates the hand crank 237 of the test component 23, which drives the rotating threaded rod 233 to rotate and move downward in the rotating threaded ring 232. The connecting plate 234, the clamping plate 231 and the test pressing block 236 descend accordingly until the test pressing block 236 contacts the test object and applies pressure.

[0040] Pressure sensor 223 transmits real-time pressure signals to pressure gauge 24 and control printing mechanism 3 via data connection line 25. Control panel 31 processes the data and displays pressure change curve on display screen 32.

[0041] After the test is completed, rotate the manual crank 237 in the opposite direction to reset the test pressing block 236, release the positioning clamp plate 221 to remove the test object, and the operator can control the printing outlet 33 to print the test report through the control panel 31. Finally, turn off the power switch 35 and cover the dust cover 34 of the printing outlet 33.
