Description

Technical Field

[0001] This invention relates to the field of wire and cable testing technology, specifically to an insulation testing device for wires and cables. Background Technology

[0002] Electric wires and cables are the core carriers of power transmission and signal transmission. The integrity of their insulation layer directly determines the safety and stability of power transmission. If the insulation layer has defects such as damage or aging, it is very easy to cause safety accidents such as leakage, short circuit or even fire. Therefore, insulation performance testing is an essential and critical step in the production, laying and operation and maintenance of electric wires and cables. Currently, existing wire and cable insulation testing devices have many shortcomings, making it difficult to meet the needs of efficient and accurate testing: First, most testing devices can only test cables of a single specification. When testing cables of different radii and models, the entire testing probe assembly must be replaced, which is cumbersome, inefficient, and prone to wear and tear, affecting testing accuracy. Second, the position adjustment of the testing probe lacks flexibility, making it impossible to quickly switch testing positions. Furthermore, positioning deviations are prone to occur during movement, resulting in an incomplete testing range and difficulty in accurately capturing insulation defects. Third, the conductive connection between the cable and the testing circuit is cumbersome, time-consuming, and has poor connection stability, easily leading to poor contact and affecting the transmission of testing signals. To address the aforementioned technical issues, there is an urgent need to design a wire and cable insulation testing device that can adapt to various cable specifications, clamp securely, adjust flexibly, and provide convenient conductive connections, in order to overcome the shortcomings of existing technologies and meet actual testing needs.

[0026] In some embodiments of the present invention, reference is made to... Figure 7 - Figure 9 As shown, the conductive probe testing unit 500 includes a telescopic cylinder 510, an upper detection guide wheel 520 and a lower detection guide wheel 530.

[0028] By adjusting the cross arm 430 end of the rotating arm 400 to set multiple sets of conductive probe test sections 500, the concave arc of the metal wheel 523 of each set of conductive probe test sections 500 matches the radius of different types of cables 900.

[0029] In some embodiments of the present invention, reference is made to... Figure 10 As shown, the cable clamping and fixing frame 600 includes a support base 610, a wire through port 620, a second cylinder 630, a clamping block 640, and rubber pads 650. The support base 610 is fixed on the base plate 100. The wire through port 620 is opened at the upper end of the support base 610 for the wire 720 to pass through. The second cylinder 630 is installed on the side of the support base 610. The clamping block 640 is connected to the telescopic end of the second cylinder 630. The rubber pads 650 are respectively installed on the lower end face of the clamping block 640 and the upper end face of the support base 610.

[0030] The cable clamping and fixing frame 600 uses cylinder 630 to drive clamping block 640 in conjunction with support base 610 to clamp cable 900. The clamping force can be precisely adjusted by cylinder 630. At the same time, the rubber pads 650 on clamping block 640 and support base 610 can protect cable 900 and prevent damage to the insulation layer due to excessive clamping force. Meanwhile, the clamped cable 900 is in a straight state, which prevents cable 900 from shaking or shifting during the test. This solves the problems of unstable clamping, easy damage to cable 900, and easy misjudgment in the test of existing devices, and ensures the stability and accuracy of the test.

[0031] In some embodiments of the present invention, reference is made to... Figure 10 - Figure 12As shown, the quick-connect bracket 800 includes a quick-reset rod 810 and a conductive sleeve 820. The quick-reset rod 810 is movably inserted into the upper end of the support base 610, and the conductive sleeve 820 is connected to the quick-reset rod 810 and electrically connected to the wire 720.

The first plate 812 is connected to one end of the pull rod 811, and the second plate 813 is connected to the other end of the pull rod 811. The spring 814 is fitted onto the pull rod 811, with one end abutting against the second plate 813 and the other end abutting against the side of the support base 610. The guide post 815 is fixedly connected to the lower end of the second plate 813 and movably inserted into a pre-set guide hole in the support base 610. The conductive sleeve 820 is connected to the upper end of the first plate 812.

[0033] Furthermore, the conductive sleeve 820 includes an insulating sleeve 821 and a copper sheet 822. The insulating sleeve 821 is connected to the upper end of the plate 812, and the copper sheet 822 is fixed inside the insulating sleeve 821 and electrically connected to the wire 720.

[0034] The quick-connect guide 800 moves the conductive sleeve 820 by pulling the pull rod 811. After releasing the pull rod 811, the spring 814 resets and drives the conductive sleeve 820 to make tight contact with the end of the cable 900. The copper sheet 822 achieves a quick conductive connection. The operation is convenient, time-saving, and the connection is stable. It solves the problems of cumbersome conductive connection and poor contact in existing devices and ensures the stable transmission of detection signals.

[0035] The operating steps of this device are as follows, with a detailed explanation of the entire testing process in conjunction with the functions of each component: 1. Preparation: Check the installation of each component of the device to ensure that each component is firmly connected and operates smoothly; check whether the power supply of the power supply unit 700 is normal, whether the wire 720 is firmly connected, and whether the electrical signal sensor 521 is working properly; according to the model of the cable 900 to be tested, determine the corresponding conductive probe test part 500, that is, a set whose concave arc of the corresponding metal wheel 523 matches the cable radius. 2. Cable clamping and fixing: Pull the lever 811 of the quick-connect guide frame 800. The lever 811 drives the first plate 812 and the second plate 813 to move downwards, compressing the spring 814. The conductive sleeve 820 moves downwards with the first plate 812, leaving space for the cable. Pass one end of the cable 900 to be tested through the gap between the clamping block 640 and the support base 610, and fix the other end to another set of cable clamping and fixing frames 600. Activate cylinder 630. The telescopic end pushes the clamping block 640 downward, and the clamping block 640 cooperates with the support base 610 to firmly clamp the cable 900 through the rubber gasket 650, ensuring that the cable 900 is in a straight state and avoiding shaking; when the pull rod 811 is released, the spring 814 returns to its original position, pushing the second plate 813, the pull rod 811, and the first plate 812 upward, and the copper sheet 822 of the conductive sleeve 820 makes close contact with the end of the cable 900, realizing a quick conductive connection between the cable 900 and the power supply unit 700; 3. Probe Switching and Positioning: Start servo motor 2 410. The shaft of servo motor 2 410 drives turntable 420 and cross arm 430 to rotate, rotating the conductive probe test section 500 of the corresponding specification determined in step 1 to the detection position, which is parallel to the cable 900. When the cross arm 430 rotates to the detection position, the movable iron block 433 in the inner groove 431 on the side of the cross arm 430 is attracted by magnet 2 444 in the positioning slot 443 of the support 442 (magnet 2 444 has a stronger magnetic force than magnet 1 432). The movable iron block 433 extends out from the inner groove 431, with one end inserted into the positioning slot 443 and the other end remaining in the inner groove 431, achieving precise positioning of the cross arm 430 and preventing the cross arm 430 from rotating off-center during subsequent movement. Turn off servo motor 2 410 to keep the cross arm 430 in the positioning state. 4. Probe contact with cable: Activate cylinder 511. The telescopic end of cylinder 511 pushes the reinforcing block 512, connecting plate 513 and upper detection guide wheel 520 downward until the metal wheel 523 of the upper detection guide wheel 520 is in close contact with the upper surface of the cable 900. At this time, the metal wheel 523 of the lower detection guide wheel 530 is in close contact with the lower surface of the cable 900, ensuring good contact between the metal wheel 523 and the cable 900. 5. Cable Insulation Testing: Power supply unit 700 is activated, and power supply box 710 supplies power to cable 900 via wire 720 and copper sheet 822. Servo motor 240 is activated, and its output drives lead screw 220 to rotate. Driven by lead screw 220, slide 250 moves smoothly along limit guide rod 230. Slide 250 drives connecting arm 300, adjusting arm 400, and conductive probe testing unit 500 to move together along the length of cable 900, thus achieving full-length insulation testing of cable 900. Insulation testing; during the testing process, if the insulation layer of cable 900 is intact, the metal wheel 523 is not conductive, and the electrical signal sensor 521 has no signal output; if the insulation layer of cable 900 has defects such as damage or aging, the metal wheel 523 conducts electricity with the cable core through the damaged area, and the current is transmitted to the electrical signal sensor 521 through the metal wheel 523 and the conductive metal shaft 522. After detecting the electrical signal, the electrical signal sensor 521 issues an alarm signal to prompt the testing personnel that there is an insulation defect here, and records the location of the defect; 6. End of Detection and Reset: After the conductive probe test section 500 moves to the other end of the cable 900 and completes the full-length detection, turn off servo motor 240; start cylinder 511, the telescopic end of cylinder 511 drives the upper detection guide wheel 520 to move upward and disengage from the cable 900; start servo motor 410, servo motor 410 drives the turntable 420 and the cross arm 430 to rotate slightly, and the movable iron block 433 moves out from the upper end of the positioning slot 443. At this time, magnet 43... The adsorption force of the movable iron block 433 plays a dominant role, and the movable iron block 433 is adsorbed back into the inner groove 431, shutting off the servo motor 410; starting the cylinder 630, the telescopic end of the cylinder 630 drives the clamping block 640 to move upward, releasing the clamp on the cable 900; pulling the pull rod 811, causing the conductive sleeve 820 to disengage from the end of the cable 900, and taking out the tested cable 900; shutting off the power supply unit 700, resetting all components to their initial positions, and preparing for the next test; 7. Switching between different cable specifications: When it is necessary to test cables 900 of different models and radii, there is no need to disassemble the conductive probe test section 500. Simply repeat steps 1-6, and use the servo motor 410 to drive the cross arm 430 to rotate, and switch to the conductive probe test section 500 of the corresponding specification. The operation is convenient and greatly improves the testing efficiency.
