Description

Technical Field

[0001] The utility model relates to the technical field of insulating rope detection, in particular to an insulating rope pressure-resistant device. Background Art

[0002] Insulating rope is generally woven from multiple strands of fine steel wire or chemical fiber. It is a rope made of insulating material that has been specially designed, improved, tested and maintained. It is usually used for live working. To ensure the insulation performance of the insulating rope is good, it must be regularly electrically tested every year to detect its insulation performance.

[0003] After searching, the patent publication number CN206096347U discloses an insulating rope withstand voltage test device. Although the device winds the insulating rope to be tested through the test rope drum during use and presses its outer side through the conductive voltage plate device, which is suitable for the insulation performance test of the insulating rope, the device needs to reel the insulating rope before testing when it is used, and it is impossible to continuously test the insulating rope, and the testing efficiency of the insulating rope is low. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an insulating rope pressure-resistant device, which solves the problems raised in the background technology.

[0005] The utility model solves the above-mentioned technical problems as follows:

[0006] The insulating rope pressure-resistant device includes a fixed plate, a protective cover is installed on the fixed plate, a conductive wheel is installed on the fixed plate inside the protective cover, a pressure wheel is installed on one side of the conductive wheel on the fixed plate, and a displacement mechanism is installed on the back of the pressure wheel on the fixed plate;

[0007] The conductive wheel is provided with a conductive slip ring, and the conductive wheel is rotatably mounted on the fixed plate through the conductive slip ring. An end of the conductive wheel located outside the conductive slip ring is provided with an end cap;

[0008] The fixed plate is provided with a slide groove, a slider is slidably installed in the slide groove, the pressure wheel is rotatably installed on the slider through a bearing, a nut seat is provided on the slider, the displacement mechanism is provided with a fixed block and a support, a screw rod is rotatably installed between the fixed block and the support, a motor is installed on the end of the fixed block away from the screw rod, and the motor is transmission-connected to the screw rod, and the slider is slidably installed in the slide groove through the nut seat and the screw rod.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, grooves are provided at the upper and lower ends of the protective cover, and a guide shaft is installed in the groove of the protective cover through a rotating shaft. The guide shaft guides the insulating rope during the insulating rope detection to prevent the insulating rope from scratching the protective cover.

[0011] The beneficial effects of adopting the above further scheme are:

[0012] The guide shaft design allows the insulating rope to smoothly follow the predetermined path during testing, avoiding direct contact and scratching with the protective cover. This significantly reduces wear and tear on the insulating rope due to friction, extending its service life. The guide shaft's guidance ensures that the insulating rope maintains a stable position and state during testing, reducing testing errors caused by movement or deviation. This helps improve detection accuracy and reliability.

[0013] Furthermore, there are two conductive wheels in total, and the two conductive wheels are connected to the outside through a conductive slip ring.

[0014] The beneficial effects of adopting the above further scheme are:

[0015] The two conductive wheels can more effectively clamp and secure the insulating rope, ensuring good contact between the rope and the wheels during testing. This stable contact helps reduce errors caused by poor contact or slippage, thereby improving detection accuracy. Connecting the two conductive wheels to an external power source via conductive slip rings enables stable current transmission. The conductive slip rings have a compact design and simple structure, and offer excellent wear and corrosion resistance and high-temperature stability, making them adaptable to harsh working environments. This stable current transmission ensures the continuity and stability of the testing process. Due to the design of the two conductive wheels and the conductive slip rings, the device can perform continuous testing of the insulating rope without the need for prior reeling or interrupting the testing process. This continuous testing capability significantly improves testing efficiency, saving time and labor costs.

[0016] Furthermore, the pressure wheel presses and fixes the insulating rope on the two conductive wheels, and the insulating rope is energized and pressurized for detection through the two conductive wheels.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] The design of the pressure wheel ensures that the insulating rope is stably pressed between the two conductive wheels, forming a close contact. This close contact not only facilitates the uniform transmission of current, but also reduces errors caused by poor contact. Through the compacting action of the pressure wheel, the insulating rope is less likely to slip or deflect during the test process, thus ensuring the stability and accuracy of the test. Due to the coordinated action of the pressure wheel and the conductive wheel, the device can achieve continuous testing of the insulating rope without interruption or readjustment. This continuous testing capability greatly improves testing efficiency and saves time and labor costs. During the power-on and pressure-applied testing process, the conductive wheel can quickly transmit voltage and current to the insulating rope and provide real-time feedback on the test results. This rapid response capability helps to promptly identify potential problems with the insulating rope.

[0019] Furthermore, the protective cover and the fixing plate are both provided with through holes, and the guide shaft is rotatably mounted on the through holes of the protective cover and the fixing plate via a rotating shaft.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] Through holes in the protective cover and mounting plate, the guide shaft is precisely positioned to ensure the insulating rope follows the intended path during testing. This precise guidance reduces friction and scratches between the insulating rope and the protective cover, protecting the rope surface from damage. The guide shaft's rotatable mounting ensures smooth rope movement, preventing testing errors caused by wobbling or drifting.

[0022] Furthermore, the two conductive wheels are both located in a protective cover, and the protective cover shields and protects the conductive wheels.

[0023] The beneficial effects of adopting the above further scheme are:

[0024] The protective cover completely encloses the conductive wheel, effectively isolating it from direct contact with the external environment and reducing the risk of electric shock to operators. This isolation is particularly important during high-voltage testing. The protective cover also prevents foreign debris and dust from entering the conductive wheel area, preventing damage to the wheel or affecting test results.

[0025] The utility model provides an insulating rope pressure-resistant device, which has the following beneficial effects:

[0026] By designing a guide shaft, the insulating rope can be effectively guided during testing, preventing unnecessary scraping between the insulating rope and the protective cover, thereby protecting the integrity of the insulating rope and extending its service life.

[0027] The design of the protective cover not only blocks the conductive wheel, but also forms a relatively closed detection space, reducing the interference of external factors on the detection process and improving the safety and accuracy of the detection.

[0028] The pressure wheel is precisely adjusted through a displacement mechanism (including a motor, a lead screw, etc.). It can automatically adjust the pressure on the insulating rope according to the thickness of the insulating rope and the detection requirements, ensuring good contact between the conductive wheel and the insulating rope and improving the detection efficiency.

[0029] The conductive wheel is connected to the outside through a conductive slip ring, enabling power-on and pressure-applying testing of the insulating rope. The design of two conductive wheels increases the reliability and stability of the test, enabling a more accurate assessment of the insulating rope's withstand voltage performance.

[0040] Example 1

[0041] The insulating rope pressure-resistant device includes a fixed plate 2, on which a protective cover 1 is mounted. Grooves 103 are provided at the upper and lower ends of the protective cover 1. A guide shaft 102 is rotatably mounted in the groove 103 of the protective cover 1 via a rotating shaft 101. Through holes 202 are provided in both the protective cover 1 and the fixed plate 2. The guide shaft 102 is rotatably mounted in the through holes 202 of the protective cover 1 and the fixed plate 2 via the rotating shaft 101. Through the through holes 202 provided in the protective cover 1 and the fixed plate 2, the guide shaft 102 can be precisely mounted in a designated position, ensuring that the insulating rope can accurately move along a predetermined path during testing. This precise guidance helps minimize friction and scratching between the insulating rope and the protective cover 1, effectively protecting the surface of the insulating rope from damage. The rotatable installation of guide shaft 102 ensures smooth movement of the insulating rope, avoiding detection errors caused by shaking or deviation. Guide shaft 102 guides the insulating rope during testing, preventing it from rubbing against protective cover 1. The ingenious design of guide shaft 102 ensures that the insulating rope can pass smoothly along a predetermined path during testing, completely avoiding direct contact and scratching with protective cover 1. This design significantly reduces wear on the insulating rope caused by friction, significantly extending its service life. Thanks to the guiding effect of guide shaft 102, the insulating rope can maintain a stable position and state during testing, significantly reducing detection errors caused by movement or deviation, thereby significantly improving detection accuracy and reliability. Conductive wheels 3 are mounted on the fixed plate 2 within protective cover 1. Both conductive wheels 3 are located within protective cover 1 and shielded by protective cover 1. The protective cover 1 completely encloses the conductive wheels 3, effectively isolating them from direct contact with the external environment and significantly reducing the risk of electric shock to operators. This isolation is particularly important during high-voltage testing. The protective cover 1 also prevents foreign matter or dust from entering the area of ​​the conductive wheels 3, thereby avoiding damage to the conductive wheels 3 or affecting the test results. A pressure wheel 4 is installed on the fixed plate 2, located on one side of the conductive wheels 3. The pressure wheel 4 presses and fixes the insulating rope onto the two conductive wheels 3. The insulating rope is then energized and pressurized by the two conductive wheels 3 for testing. The ingenious design of the pressure wheel 4 ensures that the insulating rope is stably pressed between the two conductive wheels 3, forming a close contact. This close contact not only helps to evenly transmit the current but also effectively reduces errors caused by poor contact. The pressing action of the pressure wheel 4 makes the insulating rope less likely to slip or deviate during the testing process, thereby effectively ensuring the stability and accuracy of the test. Due to the perfect coordination between the pressure wheel 4 and the conductive wheels 3, the device can achieve continuous testing of the insulating rope without interruption or readjustment. This continuous testing capability greatly improves testing efficiency and saves a considerable amount of time and labor costs. During the energization and pressurization test process, the conductive wheels 3 can quickly transmit voltage and current to the insulating rope and provide real-time feedback on the test results.This rapid response capability helps promptly identify potential problems with the insulating rope. The fixed plate 2 is located behind the pressure wheel 4 and is equipped with a displacement mechanism 5. The conductive wheel 3 is provided with a conductive slip ring 301, which is rotatably mounted on the fixed plate 2. Two conductive wheels 3 are provided, and both wheels 3 are connected to the outside world via the slip ring 301. The careful arrangement of the two conductive wheels 3 effectively clamps and secures the insulating rope, ensuring close and good contact between the rope and the conductive wheels 3 during the inspection process. This stable contact helps minimize errors caused by poor contact or slippage, thereby improving inspection accuracy. Connecting the two conductive wheels 3 to an external power source via the slip ring 301 ensures stable current transmission. The slip ring 301 features a compact design and simple structure, and offers excellent wear and corrosion resistance and high-temperature stability, making it easily adaptable to harsh working environments. This stable current transmission ensures the continuity and stability of the inspection process. Due to the unique design of the two conductive wheels 3 and the slip ring 301, the device can continuously inspect the insulating rope without requiring prior reeling or interrupting the inspection process. This continuous detection capability greatly improves the detection efficiency and saves a lot of time and labor costs. An end cover 302 is provided at one end of the conductive wheel 3 located outside the conductive slip ring 301 .

[0042] Example 2

[0043] In order to facilitate the adjustment of the position of the pressure wheel 4 so that the insulating rope is tightly pressed onto the two conductive wheels 3, for example, Figures 1 to 4 As shown, the present invention also includes: a slide groove 201 is formed on the fixed plate 2, a slider 402 is slidably installed in the slide groove 201, a pressure wheel 4 is rotatably installed on the slider 402 via a bearing 401, a nut seat 403 is provided on the slider 402, a displacement mechanism 5 is provided with a fixed block 502 and a support 504, a screw 503 is rotatably installed between the fixed block 502 and the support 504, a motor 501 is installed on the end of the fixed block 502 away from the screw 503, and the motor 501 is transmission-connected to the screw 503, the slider 402 is slidably installed in the slide groove 201 via the nut seat 403 and the screw 503, and the precise fit between the screw 503 and the nut seat 403 enables the slider 402 to slide with high precision in the slide groove. This design allows the position of the pressure wheel 4 to be precisely adjusted, meeting the requirements for accurate detection or processing of insulating ropes. The self-locking transmission mechanism of screw 503 ensures that when motor 501 stops, slider 402 remains firmly in its current position, resisting external forces. This ensures accurate and stable testing. The transmission connection between motor 501 and screw 503 enables automated adjustment of the position of pinch roller 4. The operator can easily achieve precise movement of pinch roller 4 simply by controlling the start, stop, and direction of motor 501, significantly improving work efficiency and convenience.

[0044] Working principle:

[0045] The fixed plate 2 serves as the basis of the entire device, on which a protective cover 1 is installed. Grooves 103 are provided at the upper and lower ends of the protective cover 1 for installing a guide shaft 102. The guide shaft 102 is rotatably installed at the through hole 202 of the protective cover 1 and the fixed plate 2 via a rotating shaft 101, ensuring that the insulating rope can pass smoothly and be guided during the detection process to prevent scratches. Two conductive wheels 3 are installed inside the protective cover 1, which are rotatably installed on the fixed plate 2 via a conductive slip ring 301 and are connected to an external power supply. The pressure wheel 4 is installed on the fixed plate 2, located on one side of the conductive wheel 3, and is used to press and fix the insulating rope on the two conductive wheels 3.

[0046] The insulating rope to be tested is placed between the two conductive wheels 3 and the pressure wheel 4. The position of the pressure wheel 4 is adjusted so that the insulating rope is tightly pressed against the two conductive wheels 3 to ensure good contact between the insulating rope and the conductive wheels 3.

[0047] Connect an external power source to the conductive slip ring 301 of the conductive wheel 3 to provide the required voltage. When the power source is turned on, current flows through the conductive wheel 3 into the insulating rope, performing a pressure test on the insulating rope. During the test, the changes in current and voltage can be monitored to assess the insulating rope's withstand voltage performance.

[0048] During the specified testing time, observe the insulating rope for signs of breakdown or flashover. Also, record parameters such as current and voltage during the test. Determine whether the insulating rope is qualified based on the test results and relevant standards. If the insulating rope does not show signs of breakdown or flashover during the test, and the current and voltage parameters meet the requirements, the insulating rope is considered qualified.
