Description

Technical Field

[0001] This invention relates to the field of cable testing technology, specifically to a device for testing the insulation performance of cables. Background Technology

[0002] In fields such as power transmission, communication networks, and industrial control, cables serve as the core carriers of electrical energy and signal transmission, and their insulation performance directly determines the safety, stability, and service life of the transmission system. Cable insulation layers, including materials such as cross-linked polyethylene, polyvinyl chloride, and rubber, are prone to cracking, damage, and localized aging during production, installation, and long-term use due to material defects, mechanical damage, and environmental aging factors such as high temperature, humidity, and chemical corrosion.

[0003] As the core carrier of electrical energy and signal transmission, the insulation layer of cables is a crucial structure for preventing leakage, short circuits, and signal interference. Defects in the insulation layer can lead to serious consequences such as leakage, fire, and equipment damage. Cable insulation testing devices are specialized equipment for testing the performance of the insulation layer, and their core function is to detect insulation defects through standardized and automated methods.

[0010] Preferably, an electric push rod is provided on the outside of the processing ring, and an adjusting ring two is fixedly connected to the output end of the electric push rod. A limit support plate is slidably connected to the inner wall of the adjusting ring two, and the outer wall of the limit support plate is fixedly connected to the outer wall of the processing ring.

[0011] Preferably, the outer wall of the second adjusting ring is hinged with an adjusting rod, the end of the second adjusting rod is connected to an application chamber by a rotating shaft, the middle of the application chamber is hinged with a limiting rod, the outer wall of the limiting rod is rotatably connected to the outer wall of the processing ring, and the bottom end face of the application chamber is equipped with an application cotton block, an application shell or a nozzle.

[0012] Preferably, the inside of the application chamber is provided with a storage cavity. The inner wall of the application chamber is fixedly connected with a conduit. The conduit has a through hole in the middle and its top is connected to the inside of the material hopper. The inside of the material hopper is provided with a pre-storage chamber for storing the application repair liquid. The top of the conduit extends into the inside of the material hopper and connects to the pre-storage chamber, and the bottom through hole connects to the inside of the storage cavity of the application chamber.

[0013] Preferably, the coating shell is provided with two sets of coating balls with their ends touching. The outer walls of the two sets of coating balls are rotatably connected with sealing rings.

[0014] Preferably, the auxiliary component includes a limiting block, the outer wall of which is slidably connected to the inside of the detection stage, a second screw is rotatably connected to the inside of the limiting block, one end of the second screw is fixedly connected to a handle, a spring is fixedly connected to the lower side of the limiting block, and the bottom end of the spring is fixedly connected to the upper surface of the detection stage.

[0015] Preferably, the outer wall of the screw two is threadedly connected to an adjusting ring one. The adjusting ring one is provided with multiple sets of rectangular shapes, and two sets are connected by a connecting rod. On the other side, the inner wall of the adjusting ring one is slidably connected to a guide block. Multiple sets of limiting blocks are provided, and another set is connected to the guide block. The right side of the guide block is slidably connected to the outer wall of the detection table.

[0016] Working principle: When this device is needed, first start the motor on the outer wall of the base, which drives the shaped shaft to rotate the gear sleeve. When feeding material, the pneumatic push rod drives the slider, collar, and gear sleeve to mesh with the adjusting gear on the right. When the gear sleeve drives the right adjusting gear to rotate, the gear body fixed on the outer wall of the right adjusting gear rotates. The gear body meshes with the lower side of the rack, and the rack slides along the inner wall of the base through the slider, thereby driving the upper gear body to rotate, which in turn drives the flipping rod to flip. Thus, during use, the flipping rod drives the clamping plate to flip, thereby performing the material feeding operation. After the clamping plate has flipped over, the cable to be tested is wound around the take-up drum and placed directly below the clamping plate. At this time, by activating the pneumatic push rod, the position of the adjusting collar and the gear sleeve is engaged with the adjusting gear on the left, thereby driving the screw to rotate and driving the clamping plate and the mounting sleeve to clamp the take-up drum. This achieves the effect of quick installation and feeding during use. After clamping, the position of the adjusting gear sleeve is engaged with the adjusting gear on the left by the pneumatic push rod, thereby flipping the clamping plate back to its original position. This achieves the effect of quick feeding during use, reducing the physical consumption caused by manual installation, and reducing labor costs.

[0017] By passing one end of the cable through the testing table, the cable is pre-supported when it enters the testing table. When it comes into contact with the cable, the screw is rotated by the handle to adjust its position. During use, the cable can be fixed with auxiliary support according to its actual thickness. During processing, as the amount of cable on the winding drum decreases during testing, the position of the cable will change. The spring and limit block play an adaptive support role as the cable decreases, preventing the testing position from shifting due to the reduction of cable.

[0018] With the auxiliary support of the testing platform, the cable passes through the testing magnetocoil for testing, and the detected defects are transmitted to the sensor. The control system controls the processing ring to mark or repair the defects. When the processing ring needs to perform an operation, the electric push rod controls the adjusting ring to slide under the limit of the limit plate. The adjusting ring drives the adjusting rod under the limit of the limit rod, and adjusts the position of the coating chamber, coating cotton block, coating shell or nozzle, thereby repairing and marking defective positions. In use, it can detect and mark cables of different thicknesses.

[0019] This invention provides a device for testing the insulation performance of cables. It has the following advantages:

[0020] 1. This invention uses an adjustment component to flip the clamping plate for loading and unloading materials via a flipping rod during use. Simultaneously, the adjustment component engages with the adjusting sleeve and gear, and the screw controls the clamping plate and mounting sleeve to clamp and install materials. This allows for the installation of winding drums of different sizes during use.

[0021] 2. This invention uses an electric push rod to drive the adjusting ring to slide under the limit of the limiting support plate, thereby driving the adjusting rod, the limiting rod and the coating chamber to adjust their positions. This allows for the application of coatings to cables of different thicknesses during use, thus achieving the effect of marking and repair. The spray nozzle, coating cotton block and coating shell enable the application and marking operations in different scenarios, making it adaptable to different working conditions during use.

[0022] 3. During use, this invention provides auxiliary support and guidance for cable feeding. By rotating the screw two through the handle, it can be adjusted to accommodate cables of different thicknesses for auxiliary guidance. The spring and limit block can correct the cable position and assist in deviation detection when the cable on one side decreases, thus avoiding deviation. Attached Figure Description

Detailed Implementation

[0034] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1:

[0036] Please see the appendix Figure 1 -Appendix Figure 3 This invention provides a device for testing the insulation performance of cables, including a base 1. A motor 2 is fixedly connected to the outer wall of the base 1. A shaped shaft 3 is fixedly connected to the output end of the motor 2. An adjusting gear 5 is rotatably connected to the outer wall of the shaped shaft 3. Two sets of adjusting gears 5 are mirror-arranged. A screw 13 is fixedly connected to the outer wall of one set of adjusting gears 5. A clamping plate 14 is threadedly connected to the outer wall of the screw 13. Two sets of clamping plates 14 are arranged oppositely and slide inside the base 1. A mounting sleeve 15 is fixedly connected to the outer wall of each set of clamping plates 14. The inner wall of the sleeve 15 is slidably connected to the winding drum 16, and the outer wall of the adjusting gear 5 on the other side is fixedly connected to the gear body 10. The tooth ends of the gear body 10 are meshed with the rack 11. The outer wall of the rack 11 is fixedly connected to the limit rod 12 and slidably connected to the inner wall of the base 1. The inner wall of the gear body 10 is fixedly connected to the square flipping rod, which is sleeved on the outside of the screw 13 and slides on one side of the clamping plate 14. The outer wall of the irregular shaft 3 is provided with an adjustment component, and one side of the base 1 is provided with a detection component. The inside of the detection component is provided with an auxiliary component.

[0037] Specifically, when feeding is required, motor 2 drives the irregular shaft 3 to rotate, which in turn drives the gear sleeve 4 to rotate. The position of the gear sleeve 4 is adjusted using an adjusting assembly. During feeding, the right-side adjusting gear 5 is first driven to rotate, which in turn drives the lower gear body 10 to rotate, thereby driving the rack 11 to rotate. The rack 11 has teeth on both its upper and lower sides. When the lower gear body 10 rotates and drives the rack 11 to move, it is limited by the limiting rod 12 and the base 1, thus driving the upper gear body 10 to flip. During use, the rotation of the upper gear body 10 drives the flipping rod, which in turn drives the clamping plate 14 to flip and pick up the material. After flipping, the pneumatic push rod 9 drives the adjusting rod 8 to mesh with the left adjusting gear 5, thereby driving the screw 13 to rotate. This drives the clamping plate 14 to center the mounting sleeves 15 on both sides, thus clamping the winding drum 16 on which the cable to be tested is mounted. Then, the pneumatic push rod 9 drives the collar 7 and collar 6 to drive the gear sleeve 4 to slide to the right on the outer wall of the irregular shaft 3 and switch again. This is then flipped again by the flipping rod, thus achieving a fast feeding effect during use. During use, a motor or other winding mechanism is set on the rear side of the mounting sleeve 15 at the tail to control the tail winding, thus achieving the winding effect during use.

[0038] Please see the appendix Figure 2 -Appendix Figure 3 The adjusting assembly includes a gear sleeve 4, the inner wall of which is slidably connected to the outer wall of the irregular shaft 3. Two collars 6 are fixedly connected to both sides of the gear sleeve 4, and a second collar 7 is rotatably connected to the middle of the two collars 6 and slidably connected to the outer wall of the gear sleeve 4. The two ends of the gear sleeve 4 are provided with tooth grooves, the shape of which is the same as the tooth tip shape of the adjusting gear 5. A pneumatic push rod 9 is fixedly connected to one side of the outer wall of the base 1. An adjusting rod 8 is fixedly connected to the output end of the pneumatic push rod 9, and the outer wall of the adjusting rod 8 is fixedly connected to the outer wall of the second collar 7.

[0039] Specifically, when the pneumatic push rod 9 is connected to the air station, the control adjustment rod 8 drives the collar 7 to slide inside the collars 6 on both sides. This causes the gear sleeve 4 to adjust its position through the collar 6. When it is in the middle, the irregular shaft 3 rotates freely. When the control gear sleeve 4 rotates with the left adjustment gear 5, it adjusts the clamping plate 14 to perform centering, clamping, and loading / unloading. When it meshes with the right adjustment gear 5, it drives the clamping plate 14 to flip, performing loading and unloading operations. During use, it achieves an adjustment effect and further enables rapid loading and unloading when testing cables, reducing manual labor consumption. When flipping for loading and unloading, weight balance is achieved by adding counterweight through the testing platform 17 installed on the upper side of the base 1, thereby preventing accidents caused by weight imbalance.

[0040] Please see the appendix Figure 4 -Appendix Figure 6 The detection assembly includes a detection platform 17, the lower surface of which is bolted to the upper surface of a base 1. A hopper 25 is fixedly connected to the upper surface of the detection platform 17. Two sets of telescopic rods 26 are provided on the inner top wall of the detection platform 17. A detection magnetocoil 27 is bolted to the bottom of one set of telescopic rods 26. A processing ring 28 is bolted to the bottom of the other set of telescopic rods 26. An electric push rod 29 is provided on the outside of the processing ring 28. An adjusting ring 30 is fixedly connected to the output end of the electric push rod 29. A limit support plate 31 is slidably connected to the inner wall of the adjusting ring 30. The outer wall of the limit support plate 31 is fixedly connected to the outer wall of the processing ring 28.

[0041] Specifically, after the cable is installed, it is fed into the testing station 17 and then passes through the testing magneto-coil 27 and the processing ring 28 for testing. The position of the testing magneto-coil 27 and the processing ring 28 can be adjusted by the telescopic rod 26 during use, thus enabling the cable to be tested and its position adjusted according to actual needs. The processing ring 28 is used for marking and applying repair fluid. When a defect is detected, the position is detected by a sensor, and when different current signals are detected, the position is marked or repair fluid is applied. When the electric push rod 29 is activated to drive the adjusting ring 30 to slide on the outer wall of the limiting support plate 31, the adjusting rod 32 can be driven to control the clamping operation of the application chamber 34, thus enabling the marking and treatment of cables of different thicknesses.

[0042] Please see the appendix Figure 5 -Appendix Figure 7 An adjusting rod 32 is hinged to the outer wall of the adjusting ring 30. The end of the adjusting rod 32 is connected to an application chamber 34 via a pivot. A limiting rod 33 is hinged to the middle of the application chamber 34. The outer wall of the limiting rod 33 is rotatably connected to the outer wall of the treatment ring 28. An application cotton block 35 is installed on the bottom surface of the application chamber 34. A storage cavity is provided inside the application chamber 34. A conduit 36 ​​is fixedly connected to the inner wall of the application chamber 34. A through hole is provided in the middle of the conduit 36 ​​and its top is connected to the inside of the material hopper 25. A pre-storage chamber is provided inside the material hopper 25 for storing the application repair liquid. The top of the conduit 36 ​​extends into the inside of the material hopper 25 and connects to the pre-storage chamber, and its bottom through hole connects to the inside of the storage cavity of the application chamber 34.

[0043] Specifically, when the adjusting ring 30 is pushed or pulled, it is limited by the adjusting rod 32, which simultaneously causes the coating chamber 34 to clamp and open. In the process of use, the coating cotton block 35 is controlled to mark and repair the unqualified locations. During use, the paint or repair liquid in the pre-storage chamber inside the material hopper 25 is transported to the coating chamber 34 through the conduit 36. When the sensor detects an unqualified location, the electric push rod 29 controls the coating cotton block 35 to clamp, thereby allowing the paint or repair liquid in the coating chamber 34 to penetrate onto the coating cotton block 35. This achieves the effect of coating and repairing the cable during movement detection, achieving the effects of area repair and local marking during use.

[0044] Please see the appendix Figure 10 The auxiliary components include a limiting block 19, whose outer wall is slidably connected to the inside of the testing table 17. A screw 21 is rotatably connected inside the limiting block 19, with a handle 20 fixedly connected to one end of the screw 21. A spring 18 is fixedly connected to the lower side of the limiting block 19, and the bottom end of the spring 18 is fixedly connected to the upper surface of the testing table 17. An adjusting ring 22 is threadedly connected to the outer wall of the screw 21. Multiple sets of adjusting rings 22 are arranged in a rectangular configuration, with two sets connected by a connecting rod 23. A guide block 24 is slidably connected to the inner wall of the adjusting ring 22 on the other side. Multiple sets of limiting blocks 19 are arranged, with another set connected to the guide block 24. The right side of the guide block 24 is slidably connected to the outer wall of the testing table 17.

[0045] Specifically, during cable transport, the cable is pre-attached by the adjusting ring 22. Then, by rotating the handle 20, the screw 21 is rotated, thereby controlling the adjusting ring 22 for adjustment. During use, it can provide auxiliary support and guidance for cables of different thicknesses. During use, the rear adjusting ring 22 guides the tail end, thus assisting in the initial installation and testing of the cable. The spring 18 and the limiting block 19 provide auxiliary adjustment and support during use. Furthermore, during use, it can provide auxiliary guidance and support when the cable position changes due to the gradual reduction of the cable in the feeding area during testing. During movement, the guide block 24 provides auxiliary limiting to prevent deviation.

[0046] Example 2: Based on Example 1, this example further describes how to improve the application when the cotton pad 35 cannot penetrate or completely apply the product.

[0047] Please see the appendix Figure 7 -Appendix Figure 9An adjusting rod 32 is hinged to the outer wall of the adjusting ring 30. The end of the adjusting rod 32 is connected to an applicator 34 via a pivot. A limiting rod 33 is hinged to the middle of the applicator 34. The outer wall of the limiting rod 33 is rotatably connected to the outer wall of the processing ring 28. An applicator shell 37 is mounted on the bottom surface of the applicator shell 34. Two sets of applicator balls 39 are provided inside the applicator shell 37, with their ends fitting together. A sealing ring 38 is rotatably connected to the outer walls of the two sets of applicator balls 39. The sealing ring 38 is fixedly connected to the bottom and middle of the applicator shell 37 to fix the applicator balls 39.

[0048] Specifically, by replacing the sizing pad 35 with a sizing shell 37, a sealing ring 38, and sizing balls 39, the problem is solved. Because the cable moves at a fixed speed during testing, the coating and repair fluid inside the sizing chamber 34 cannot fully adhere to the entire sizing pad 35 during penetration. This results in a large amount of repair fluid or coating being carried away after the front side moves, preventing penetration on the rear side. By setting the bottom of the sizing chamber 34 in an arc shape and aligning it with the cable, the sizing shells 37 are arranged in an alternating pattern. When the sensor receives a fault signal, it clamps the outer wall of the cable to the bottom sizing balls 39, squeezing the balls upwards. This pushes the upper sizing balls 39 to seal the opening of the upper sealing ring 38, leaving a gap at the bottom. This allows the coating and repair fluid stored inside the two sealing rings 38 in the sizing chamber 34 to be applied evenly to the outside of the cable by the sizing balls 39. This solves the problem of the sizing pad 35 initially being able to completely coat the cable, but then failing to penetrate on the rear side due to the loss of coating and repair fluid.

[0049] Example 3: Based on Example 1, this example further describes how to improve the application when the cotton pad 35 and the coating shell 37 cannot penetrate and completely apply the coating.

[0050] Please see the appendix Figure 7 An adjusting rod 32 is hinged to the outer wall of the adjusting ring 30. The end of the adjusting rod 32 is connected to the application chamber 34 by a rotating shaft. A limiting rod 33 is hinged to the middle of the application chamber 34. The outer wall of the limiting rod 33 is rotatably connected to the outer wall of the processing ring 28. A nozzle is installed on the bottom surface of the application chamber 34.

[0051] Specifically, when the application cotton block 35, application shell 37, sealing ring 38 and application ball 39 fail to achieve penetration, a nozzle is installed at the bottom of the application chamber 34. When the sensor receives a fault signal, the paint and repair liquid are sprayed directly through the nozzle via the conduit 36, thereby completely covering the faulty area and achieving the effect of repair penetration and marking of the faulty area.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that many sets of variations, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
