Description

Technical Field

[0001] This application relates to the field of thread inspection technology, and in particular to an insulator thread inspection device. Background Technology

[0002] High-voltage transmission line insulators, as key components supporting conductors and preventing current from returning to the ground, play a vital role in the power grid system. Their reliable operation is crucial for ensuring stable power supply and safety of the power grid, especially the reliability of the threaded connections of the insulators, which directly affects the safety and stability of the power grid operation.

[0003] In the past, the industry commonly employed several specific methods to inspect the thread quality of insulators for high-voltage transmission lines. One common method was manual visual inspection. While relatively simple to operate and requiring no complex equipment, this method heavily relied on the experience and visual judgment of the inspectors, making it highly subjective. Simultaneously, simple torque wrenches were frequently used to roughly assess the thread connection quality by measuring the torque during tightening. However, the accuracy of simple torque wrenches was limited, making it difficult to accurately reflect the true condition of the threaded connection.

[0004] However, these existing technologies have significant drawbacks. Manual visual inspection and simple torque wrench testing have low accuracy and cannot meet the stringent requirements for insulator connection strength in ultra-high voltage lines. Furthermore, manual operation involves considerable uncertainty, easily leading to secondary damage to the threaded joints. This not only affects the accuracy of the test results but may also damage the insulators themselves, thus affecting their normal use in high-voltage transmission lines. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this application provides an insulator thread inspection device. The insulator is positioned by a fixing frame, and a nut is installed by a tightening mechanism. After the detection shaft and the clamping head are engaged, the drive unit drives the insulator to rotate and tighten. The torque sensor monitors the torque in real time, thereby realizing the detection of the insulator thread connection. This ensures that the connection meets the set requirements and guarantees the installation quality.

[0006] This application is achieved through the following technical solution:

[0007] An insulator thread inspection device includes a working platform with a fixed frame. The fixed frame has a horizontally arranged upper positioning plate with a first positioning hole for placing the insulator. Below the working platform is another fixed plate with a tightening mechanism for threading a nut to a predetermined position on the lower threaded portion of the insulator. A detection shaft is slidably connected to the fixed plate. Powered by a second vertical moving mechanism, the detection shaft is lifted to engage with the insulator. Above the working platform is a detection mechanism including a drive unit. A torque sensor is mounted on the rotating shaft of the drive unit, and a clamping head is fixed to the sensing end of the torque sensor. Powered by a third vertical moving mechanism, the detection mechanism moves vertically to move the clamping head to engage with the detection shaft. The drive unit provides rotational power to the rotating shaft to tighten the insulator and nut threads, fixing them to the upper positioning plate. The torque sensor monitors the transmission torque between the rotating shaft and the clamping head in real time.

[0008] By adopting the above technical solution, this insulator thread inspection equipment can effectively inspect the insulator threads. The upper positioning plate on the working platform can hold the insulator, and the tightening mechanism on the fixed plate can accurately thread the nut to the set position of the lower thread of the insulator. The inspection shaft can be engaged with the insulator under the drive of the second vertical moving mechanism, and the inspection mechanism above the working platform, under the action of the third vertical moving mechanism, causes the clamping head to engage with the inspection shaft. The drive unit provides rotational power to tighten the insulator and nut threads and fix them on the upper positioning plate. Simultaneously, the torque sensor can monitor the transmission torque between the rotating shaft and the clamping head in real time, thereby accurately detecting the connection status of the insulator threads and ensuring the accuracy and reliability of the inspection.

[0009] Optionally, the fixing frame further includes a lower positioning plate arranged parallel to the upper positioning plate, the lower positioning plate having a through hole for the nut to pass through; the third vertical moving mechanism includes a mounting plate arranged vertically on the working platform, the mounting plate having a vertically arranged slide rail, and a sliding plate slidably connected to the slide rail; the sliding plate is powered by a second driving mechanism to drive the sliding plate to move on the slide rail.

[0010] By adopting the above technical solution, the nut can smoothly pass through the lower positioning plate to reach the designated position. Simultaneously, the third vertical moving mechanism, composed of the mounting plate, slide rail, and sliding plate, allows the sliding plate to move smoothly on the slide rail under the power of the second drive mechanism. This structural design enables the detection mechanism to achieve precise vertical movement, thereby allowing the clamping head to accurately engage with the detection shaft. This ensures that the rotational power of the drive unit can be stably transmitted to the insulator and nut during the detection process, achieving thread tightening and improving the operational stability and detection accuracy of the testing equipment.

[0011] Optionally, the upper positioning plate is provided with a clamping mechanism for fixing the insulator in the first positioning hole; the tightening mechanism includes a lifting platform slidably connected to the fixed plate in the vertical direction, and a tightening sleeve is rotatably connected to the lifting platform; the lifting platform is powered by a first vertical moving mechanism to drive the tightening sleeve to move in the vertical direction, so that the tightening sleeve can lift the nut to abut against the insulator, and the tightening sleeve is powered by a first driving mechanism to tighten the nut and the insulator with threads and lock them on the upper positioning plate; the bottom end of the sliding plate is provided with a pressing block, and a limit switch is provided below the sliding plate.

[0012] By adopting the above technical solution, the clamping mechanism of the upper positioning plate can firmly fix the insulator in the first positioning hole, preventing the insulator from shaking or shifting during the test and ensuring the test accuracy. Under the power of the first vertical moving mechanism, the lifting platform of the tightening mechanism can lift the tightening sleeve to abut against the insulator, and then the first drive mechanism provides rotational power to tighten the threads of the nut and the insulator and lock them on the upper positioning plate, ensuring a firm connection. The pressing block at the bottom of the sliding plate, together with the limit switch below, can control the movement stroke of the testing mechanism, avoiding excessive movement that could damage the equipment, while making the testing process more automated and precise, improving testing efficiency and accuracy.

[0013] Optionally, the clamping mechanism includes a positioning seat fixed on the upper positioning plate. The positioning seat has a horizontally arranged first sliding hole, in which a clamping block is slidably connected. The clamping block is powered by an electric telescopic rod to drive the clamping block to abut against the top of the insulator.

[0014] By adopting the above technical solution, the positioning seat of the clamping mechanism is fixed on the upper positioning plate, and the first sliding hole on the positioning seat provides a horizontal sliding channel for the clamping block. The electric telescopic rod provides power to the clamping block, enabling it to abut against the top of the insulator. This structural design effectively fixes the insulator in the first positioning hole, preventing the insulator from shaking or shifting during testing, ensuring the accuracy and stability of the test. Simultaneously, the electric telescopic rod controls the movement of the clamping block, making operation convenient and allowing for flexible adjustment of the clamping force according to actual needs, ensuring reliable fixing of insulators of different specifications, and improving the versatility and practicality of the equipment.

[0015] Optionally, the end of the clamping block that abuts against the insulator has an arc-shaped structure.

[0016] By adopting the above technical solution, the end of the clamping block that abuts against the insulator is designed as an arc shape, which increases the contact area with the top of the insulator. When fixing the insulator, it can better fit the shape of the insulator, enhance the fixing effect of the insulator, prevent it from shaking or shifting during the testing process, and ensure the stability of the testing process.

[0017] Optionally, the bottom end of the lifting platform is provided with a first guide post, and the fixed plate is provided with a first guide hole adapted to the first guide post; the first guide posts are evenly distributed at the four corners of the lifting platform; the first vertical moving mechanism is a first telescopic cylinder set on the fixed plate.

[0018] By adopting the above technical solution, in the insulator thread testing equipment, the first guide posts evenly distributed at the four corners of the bottom of the lifting platform cooperate with the matching first guide holes on the fixed plate, providing precise guidance for the vertical movement of the lifting platform. This allows the lifting platform to perform stable and accurate lifting movements under the drive of the first telescopic cylinder. This avoids deviation or swaying of the lifting platform during movement, ensuring that the tightening sleeve can accurately lift the nut to abut against the insulator. Simultaneously, the first telescopic cylinder, as the first vertical moving mechanism, features stable power and fast response speed, efficiently driving the tightening sleeve to complete the thread tightening operation between the nut and the insulator, improving the working efficiency and testing accuracy of the testing equipment.

[0019] Optionally, the tightening sleeve includes a rotating cylinder rotatably connected to the lifting platform. The top of the rotating cylinder is provided with at least two vertically arranged second guide posts, and tightening heads are provided on the second guide posts. An elastic reset member is provided between the tightening head and the rotating cylinder, and the elastic reset member is sleeved on the second guide posts.

[0020] By adopting the above technical solution, the rotating cylinder of the tightening sleeve is rotatably connected to the lifting platform. A tightening head is mounted on the second guide post at its top, and an elastic reset element is fitted onto the second guide post between the tightening head and the rotating cylinder. This structure allows the tightening head to adaptively adjust its position according to the height and installation condition of the nut under the action of the elastic reset element, ensuring good contact with the nut and achieving stable tightening operation. Simultaneously, the elastic reset element can buffer the impact force during tightening, preventing damage to the nut and insulator, improving the tightening accuracy and reliability, ensuring the quality of the threaded connection between the insulator and the nut, and enhancing the working efficiency and stability of the entire testing equipment.

[0021] Optionally, the second guide post is fixed on the rotating cylinder, and the tightening head is provided with a second guide hole adapted to the second guide post; the tightening head is slidably connected to the second guide post through the second guide hole; the tightening head is provided with a positioning groove adapted to the nut in the middle.

[0022] By adopting the above technical solution, the second guide post is fixed on the rotating cylinder, and the tightening head is slidably connected to the second guide post through a matching second guide hole. This allows the tightening head to slide stably on the second guide post, ensuring accurate movement and preventing deviation. A positioning groove adapted to the nut is provided in the middle of the tightening head, allowing for precise positioning of the nut and enabling the tightening head to quickly and accurately engage with it upon contact. This structural design enhances the stability and reliability of the fit between the tightening head and the nut, better transmits torque during tightening, improves the efficiency and quality of tightening the nut and insulator threads, and ensures the insulator is securely mounted on the upper positioning plate.

[0023] Optionally, a positioning groove is provided at the edge of the positioning groove, and the positioning groove is adapted to the protrusion provided on the outer wall of the nut.

[0024] By adopting the above technical solution, a positioning groove adapted to the outer wall protrusion of the nut is set at the edge of the positioning slot, enabling more precise positioning of the nut during the operation of the testing equipment. When the tightening sleeve operates on the nut, the cooperation between the positioning groove and the nut protrusion prevents the nut from slipping or shifting during tightening, ensuring that the nut is accurately threaded into the lower threaded part of the insulator. This precise positioning helps improve the quality of the threaded connection, allowing the nut to be tightened more stably to the set position, avoiding the problem of weak connection caused by nut position deviation, thereby ensuring the accuracy and reliability of the test results of the insulator thread testing equipment, and improving the overall testing efficiency and quality.

[0025] Optionally, a movable plate is provided below the fixed plate, and a third guide post is provided at each of the four corners of the movable plate. The fixed plate is provided with a third guide hole that matches the third guide post. The fixed plate is provided with a slide seat for sliding connection of the detection shaft. The slide seat is provided with a second sliding hole, which is slidably connected to the detection shaft. The detection shaft abuts against the movable plate. The movable plate is connected to a second vertical moving mechanism, and the movable plate is powered by a second telescopic cylinder.

[0026] By adopting the above technical solution, a movable plate is set below the fixed plate. The third guide posts at the four corners of the movable plate are adapted to the third guide holes on the fixed plate, which can guide and stabilize the movement of the movable plate, ensuring the accuracy of its movement. The slide and second sliding hole in the fixed plate provide a stable sliding path for the detection shaft, allowing it to slide smoothly. The detection shaft abuts against the movable plate. When the second telescopic cylinder provides power to the movable plate, it can accurately drive the detection shaft to move within the slide, thereby realizing the bonding operation between the detection shaft and the insulator. This ensures the smooth progress of the insulator thread detection process and effectively improves the working stability and detection accuracy of the insulator thread detection equipment.

[0049] The technical solutions of various embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] Example 1

[0051] Reference Figures 1-3 This application discloses an insulator 2111 thread testing device, including a working platform 1, a fixed frame 2 on the working platform 1, an upper positioning plate 21 arranged horizontally on the fixed frame 2, and a first positioning hole 211 for placing the insulator 2111; a fixed plate 4 is provided below the working platform 1, and a tightening mechanism 5 is provided on the fixed plate 4, which is used to thread a nut 2211 onto a set position on the lower thread portion 2113 of the insulator 2111; a detection shaft 41 is slidably connected in the fixed plate 4; the detection shaft 41 is lifted to a position for contact with the insulator 2111 by a second vertical moving mechanism 42. The work platform 1 is equipped with a detection mechanism 6, which includes a drive unit 61. A torque sensor 611 is mounted on the rotating shaft of the drive unit 61, and a clamping head 612 is fixed to the sensing end of the torque sensor 611. The detection mechanism 6 is powered by a third vertical moving mechanism 62 to move vertically and move the clamping head 612 to engage with the detection shaft 41. The drive unit 61 provides rotational power to the rotating shaft to drive the insulator 2111 and the nut 2211 to be threaded together and fixed on the upper positioning plate 21. The torque sensor 611 is used to monitor the transmission torque between the rotating shaft and the clamping head 612 in real time.

[0052] Specifically, refer to Figures 2-3The upper positioning plate 21 is provided with a clamping mechanism 3, which is used to fix the insulator 2111 in the first positioning hole 211. The tightening mechanism 5 includes a lifting platform 51 that is slidably connected to the fixing plate 4 in the vertical direction. A tightening sleeve 511 is rotatably connected to the lifting platform 51. The lifting platform 51 is powered by the first vertical moving mechanism 52 to drive the tightening sleeve 511 to move in the vertical direction, so that the tightening sleeve 511 can lift the nut 2211 to abut against the insulator 2111. The tightening sleeve 511 is powered by the first driving mechanism 53 to tighten the nut 2211 and the insulator 2111 with threads and lock them on the upper positioning plate 21. The clamping mechanism 3 can securely fix the insulator 2111 in the first positioning hole 211 to prevent the insulator 2111 from shaking or shifting during the testing process; under the power of the first vertical moving mechanism 52, the lifting platform 51 can lift the nut 2211 to abut against the insulator 2111 by the tightening sleeve 511, and then the first driving mechanism 53 provides rotational power to tighten the threads of the nut 2211 and the insulator 2111 and lock them on the upper positioning plate 21 to ensure a firm connection.

[0053] Reference Figure 3 The fixing frame 2 also includes a lower positioning plate 22 arranged parallel to the upper positioning plate 21, with a through hole 221 for the nut 2211 to pass through. The end of the clamping block 3111 that abuts against the insulator 2111 has an arc-shaped structure 3113. Compared to a normal-shaped end, the arc-shaped structure 3113 allows the clamping force to be distributed more evenly on the surface of the insulator 2111, avoiding local stress concentration and damage to the insulator 2111. When fixing the insulator 2111, it can better fit the shape of the insulator 2111, enhancing the fixing effect of the insulator 2111, preventing it from shaking or shifting during the testing process, and ensuring the stability of the testing process. At the same time, this structural design also reduces wear on the surface of the insulator 2111, improves the adaptability of the testing equipment to insulators 2111 of different sizes and shapes, and helps to improve the accuracy and reliability of the testing results.

[0054] Reference Figures 3-5 The clamping mechanism 3 includes a positioning seat 31 fixed on the upper positioning plate 21. The positioning seat 31 has a horizontally arranged first sliding hole 311. A clamping block 3111 is slidably connected in the first sliding hole 311. The clamping block 3111 is powered by an electric telescopic rod 3112 to drive the clamping block 3111 to abut against the top of the insulator 2111. The positioning seat 31 is generally made of metal and is fixed to the upper positioning plate 21 by bolts. The size of its first sliding hole 311 must be adapted to the clamping block 3111 to ensure that the clamping block 3111 can slide smoothly in the first sliding hole 311.

[0055] Reference Figures 6-7A movable plate 44 is provided below the fixed plate 4. A third guide post 441 is provided at the four corners of the movable plate 44. A third guide hole 45 adapted to the third guide post 441 is provided on the fixed plate 4. A slide seat 46 for sliding connection of the detection shaft 41 is provided in the fixed plate 4. A second sliding hole 461 is provided in the slide seat 46. The second sliding hole 461 is slidably connected to the detection shaft 41. The detection shaft 41 abuts against the movable plate 44. The movable plate 44 is connected to a second vertical moving mechanism 42. The movable plate 44 is powered by a second telescopic cylinder 442. The movable plate 44 is generally a metal plate, with third guide posts 441 at its four corners. Each third guide post 441 is a cylindrical rod, and each third guide hole 45 is a smooth circular hole. The third guide posts 441 slide within the third guide holes 45, ensuring smooth vertical movement of the movable plate 44. The slide block 46 is generally a metal block, with a second sliding hole 461 inside. The second sliding hole 461 is a cylindrical hole with a smooth inner wall. The detection shaft 41 is a cylindrical rod that slides into the second sliding hole 461, ensuring smooth up-and-down movement of the detection shaft 41 within the slide block 46. The detection shaft 41 abuts against the movable plate 44. The movable plate 44 is connected to a second vertical moving mechanism 42, which is a second telescopic cylinder 442. The piston rod is connected to the movable plate 44, and the extension and retraction of the second telescopic cylinder 442 causes the movable plate 44 and the detection shaft 41 to move together in the vertical direction. When the second telescopic cylinder 442 extends, the detection shaft 41 moves upward until it engages with the insulator 2111; when the second telescopic cylinder 442 retracts, the detection shaft 41 moves downward back to its initial position. Furthermore, a support frame can be provided on the side of the moving plate 44 to fix the bottom of the fixed plate 4. This support frame further enhances the stability of the connection between the moving plate 44 and the fixed plate 4, preventing accidental shaking or displacement of the moving plate 44, thereby ensuring the accuracy of the detection shaft 41's position and improving the stability and reliability of the entire detection process.

[0056] Reference Figures 6-7 The bottom end of the lifting platform 51 is provided with a first guide post 54, and the fixed plate 4 is provided with a first guide hole 43 that matches the first guide post 54. The first guide posts 54 are evenly distributed at the four corners of the lifting platform 51. The first vertical moving mechanism 52 is a first telescopic cylinder 521 set on the fixed plate 4. The first guide post 54 is generally cylindrical and made of high-strength steel. Its function is to guide the lifting platform 51 during the lifting process and ensure the stability of the lifting. The inner diameter of the first guide hole 43 must match the outer diameter of the first guide post 54, and the gap between the two must be controlled within a certain range to ensure the accuracy of the guidance. The first telescopic cylinder 521 can be fixed to the fixed plate 4 by bolts, and its piston rod is connected to the lifting platform 51. When the first telescopic cylinder 521 works, it pushes the lifting platform 51 to move in the vertical direction.

[0057] Reference Figures 8-9 The tightening sleeve 511 includes a rotating cylinder 5111 rotatably connected to the lifting platform 51. At least two vertically arranged second guide posts 5113 are provided at the top of the rotating cylinder 5111, and tightening heads 55 are provided on the second guide posts 5113. An elastic reset member 5114 is provided between the tightening head 55 and the rotating cylinder 5111, and the elastic reset member 5114 is sleeved on the second guide posts 5113. The elastic reset member 5114 is generally a spring. When the tightening head 55 is subjected to external force, the spring is compressed. After the external force disappears, the spring returns to its original state, causing the tightening head 55 to return to its initial position.

[0058] Reference Figures 8-10 The second guide post 5113 is fixed on the rotating cylinder 5111, and the tightening head 55 is provided with a second guide hole 5112 that matches the second guide post 5113. The tightening head 55 is slidably connected to the second guide post 5113 through the second guide hole 5112. The tightening head 55 is provided with a positioning groove 551 in the middle that matches the nut 2211. The rotating cylinder 5111 is powered to rotate by the first drive mechanism 53. The output shaft of the first drive mechanism 53 is provided with a first gear 531, and the tightening sleeve 511 is provided with a second gear 532. The first gear 531 and the second gear 532 mesh to transmit power to the rotating cylinder 5111, so as to drive the tightening sleeve 511 to move in the vertical direction, so that the tightening sleeve 511 can lift the nut 2211 to abut against the insulator 2111.

[0059] Reference Figure 10 The positioning groove 551 has a positioning recess 5511 at its edge, which is adapted to the protrusion 2212 on the outer wall of the nut 2211. The positioning groove 551 can better position with the protrusion 2212 on the nut 2211, and the positioning recess 5511 further improves the positioning accuracy; in addition, the positioning recess 5511 can also transfer the torque of the nut 2211 to the insulator 2111 to achieve the tightening of the nut 2211.

[0060] Reference Figures 11-13The third vertical moving mechanism 62 includes a mounting plate 621 vertically arranged on the working platform 1. A vertically arranged slide rail 6211 is provided on the mounting plate 6211, and a sliding plate 6212 is slidably connected to the slide rail 6211. The sliding plate 6212 is powered by a second driving mechanism 6213 to move along the slide rail 6211. The mounting plate 621, vertically arranged on the working platform 1, is typically made of metal and can be fixed by bolts or welding, serving as the mounting base for the slide rail 6211. The slide rail 6211 is generally made of metal and vertically arranged on the mounting plate 621. The sliding plate 6212 is also typically made of metal and can slide along the slide rail 6211; its size is determined according to actual installation and usage requirements. The second driving mechanism 6213 provides power for the movement of the sliding plate 6212, enabling the detection mechanism 6 to move precisely in the vertical direction.

[0061] Reference Figure 13 The drive unit 61 has a torque sensor 611 on its rotating shaft. The torque sensor 611 can accurately detect torque and feed it back to the control system of the equipment.

[0062] The implementation principle of this embodiment is as follows: The insulator 2111 thread testing device, through the coordinated operation of various mechanisms, achieves comprehensive and accurate testing of the thread connection status of the insulator 2111. The tightening mechanism 5 accurately tightens the nut 2211 onto the insulator 2111, and the testing mechanism 6 monitors the torque change during the thread tightening process in real time. This avoids the problems of traditional testing methods being greatly affected by subjective factors and unable to comprehensively assess the tightening status, thus improving the accuracy and consistency of the testing results. This ensures the quality and reliability of the insulator 2111 thread connection, which is of great significance for improving the safety and stability of the power system.

[0063] Example 2

[0064] Reference Figures 14-15 The difference between this embodiment and Embodiment 1 is that a pressing block 6214 is provided at the bottom end of the sliding plate 6212, and a limit switch 6215 is provided below the sliding plate 6212. The limit switch 6215 can control the moving position of the sliding plate 6212, and plays a role in limiting and protecting it.

[0065] The implementation principle of this embodiment is as follows: During the torque detection of insulator 2111, limit switch 6215, in conjunction with pressing block 6214, precisely controls and protects the movement position of sliding plate 6212, preventing excessive movement of sliding plate 6212 from causing equipment damage, further improving the stability of equipment operation and the reliability of detection results, and ensuring the smooth progress of detection work.

[0067] Reference Figures 16-17 The difference between this embodiment and embodiment one is that the second guide post 5113 is fixed on the tightening head 55, and the rotating cylinder 5111 is provided with a second guide hole 5112 that is adapted to the second guide post 5113; the rotating cylinder 5111 is slidably connected to the second guide post 5113 through the second guide hole 5112, and the outer wall of the rotating cylinder 5111 is provided with an installation hole 5115 through which the second guide post 5113 passes.

[0068] The implementation principle of this embodiment is as follows: This structural adjustment changes the internal motion and engagement method of the tightening sleeve 511, but it can still achieve the function of the tightening sleeve 511 driving the nut 2211 to rotate and tighten with the thread of the insulator 2111. By sliding the rotating cylinder 5111 on the second guide post 5113, the tightening head 55 can also accurately drive the nut 2211 in the appropriate position, and cooperate with other components to complete the torque detection of the insulator 2111.
