Description

Technical Field

[0001] This utility model relates to the field of insulator testing technology, specifically to a tooling for measuring the dimensions of insulators. Background Technology

[0002] Insulators, as important electrical insulation components widely used in power systems, primarily function to provide electrical insulation and mechanical fixation between conductors at different potentials. In power facilities such as transmission lines and substations, insulators need to withstand the influence of various factors such as high voltage, mechanical stress, and harsh natural environments. To ensure the reliable operation of insulators, their dimensional accuracy is a crucial parameter. Appropriate dimensions ensure that insulators are correctly assembled with other components, meeting the requirements for electrical insulation distance and mechanical strength, thereby guaranteeing the safe and stable operation of the power system. Therefore, accurate dimensional inspection of insulators is an indispensable part of power production and maintenance.

[0003] However, traditional insulator size inspection technologies have many shortcomings. Some traditional inspection methods rely on manual measurement, which is not only inefficient, but also easily affected by the subjective factors of the operator, making it difficult to guarantee measurement accuracy. Some methods that use simple measuring tools are often difficult to accurately measure the dimensions of complex shapes and special parts of insulators, and cannot fully cover all the key dimensions of insulators. These shortcomings may lead to the entry of non-compliant insulators into the market or into use during actual production and inspection, thereby increasing the risk of power system failures, potentially causing power outages, and even endangering human life and causing significant economic losses. To address this, we propose a tooling for insulator size inspection. Utility Model Content

[0014] Compared with the prior art, this utility model provides a tooling for inspecting the dimensions of insulators, which has the following advantages:

[0015] 1. This fixture for inspecting the dimensions of insulators features a fixed insulator structure. A first motor drives a rotating shaft and multiple sets of insulators to rotate synchronously, enabling continuous inspection. Simultaneously, the sliding plate, driven by the rotating structure, can quickly slide on the limit block. In conjunction with the electric telescopic rod, it moves the inspection box up and down, allowing for rapid inspection of insulators at different positions. Compared to manual operation, this significantly shortens the inspection time and improves inspection efficiency, meeting the needs for rapid insulator inspection in large-scale production.

[0016] 2. This fixture for inspecting the dimensions of insulators achieves inspection through mechanical structures and components. The lead screw of the rotating structure is threadedly connected to the sliding plate, and the second motor precisely controls the movement distance of the sliding plate.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 A fixture for inspecting the dimensions of insulators includes a workbench 1, with support feet 2 fixedly installed at the four corners of the bottom of the workbench 1, rubber pads fixedly installed at the bottom of the support feet 2, a base 3 fixedly installed on one side of the top of the workbench 1, insulator fixing structures provided on both sides of the top of the base 3, a limit block 8 fixedly installed on the top of the workbench 1 corresponding to the side of the base 3, a rotating structure provided on one side of the top of the limit block 8, a sliding plate 13 slidably installed on the limit block 8, the sliding plate 13 being inverted L-shaped, and a moving structure provided on the lower surface of the top of the sliding plate 13.

[0027] Furthermore, the insulator fixing structure includes a support plate 4, a rotating shaft 5, a first motor 6, and insulators 7. A set of parallel support plates 4 are fixedly installed on both sides of the top of the base 3. Through holes are opened on the sides of the support plates 4 near the top. A rotating shaft 5 is rotatably installed between the inner sides of the set of support plates 4 facing each other. Multiple sets of linearly arranged insulators 7 are fixedly installed on the outer surface of the rotating shaft 5. A first motor 6 is fixedly installed on the outer side of one support plate 4. The output shaft of the first motor 6 is fixedly connected to the rotating shaft 5. The support plate 4 not only provides stable support for the rotating shaft 5, but the through hole design near the top of the side makes the installation of the rotating shaft 5 more convenient and ensures the stability of the rotating shaft 5 during rotation, reducing shaking. Multiple sets of linearly arranged insulators 7 are installed on the rotating shaft 5, allowing multiple insulators to be tested at once, improving testing efficiency. When the first motor 6 drives the rotating shaft 5 to rotate, the speed and direction can be adjusted according to the actual testing requirements.

[0028] Furthermore, the top of the limiting block 8 is provided with a sliding groove 9, in which a sliding plate 13 is slidably installed. The bottom of the sliding plate 13 is provided with a mounting groove 14, in which multiple sets of parallel rollers 15 are rotatably installed. The sliding groove 9 on the limiting block 8 guides the sliding of the sliding plate 13, ensuring that the sliding plate 13 can only move horizontally in the set direction, avoiding deviation, thereby ensuring the accuracy of the horizontal movement of the detection box 17 and improving detection precision. The rollers 15 in the mounting groove 14 at the bottom of the sliding plate 13 not only reduce the friction when the sliding plate 13 moves, but also share the weight of the sliding plate 13 and the components installed above it, reducing the wear between the sliding plate 13 and the limiting block 8, and extending the service life of the device. The installation method of the rollers 15 makes the movement of the sliding plate 13 more flexible. When the second motor 11 drives the lead screw 12 to move the sliding plate 13, it can respond quickly and achieve precise positioning.

[0029] Furthermore, the rotating structure includes a fixed plate 10, a second motor 11, and a lead screw 12. The fixed plate 10 is fixedly installed on the top side of the limiting block 8, and the second motor 11 is fixedly installed on the side of the fixed plate 10. The output shaft of the second motor 11 passes through the fixed plate 10 and is fixedly connected to the lead screw 12. The lead screw 12 is threadedly connected to the slide plate 13 through a threaded hole on the side of the slide plate 13. The fixed plate 10 serves to stabilize the second motor 11 and the lead screw 12, ensuring that the entire structure will not shake or shift during motor operation and lead screw transmission. The second motor 11 serves as a power source. During operation, the second motor 11 can rotate forward and backward and adjust its speed according to a preset program, precisely controlling the number of rotations and speed of the lead screw 12, thereby precisely controlling the moving distance and speed of the slide plate 13 on the limiting block 8. The threaded connection between the lead screw 12 and the slide plate 13 ensures that the slide plate 13 maintains a stable position when stopped, preventing movement due to external interference and ensuring the reliability of the detection process.

[0030] Furthermore, the movable structure includes an electric telescopic rod 16 and a detection box 17. The electric telescopic rod 16 is fixedly installed on the lower surface of the top of the slide plate 13, and the detection box 17 is fixedly installed at the bottom of the electric telescopic rod 16. A through square groove 18 is opened on the side of the detection box 17. An adjustment structure is provided inside the detection box 17. The stroke and speed of the electric telescopic rod 16 can be flexibly adjusted according to the height of the insulator and the detection requirements. When detecting insulators of different specifications, the detection box 17 can be quickly and accurately adjusted to a suitable height, improving detection efficiency. The square groove 18 on the side of the detection box 17 provides space for the sliding of the adjustment rod 19, and also facilitates the operator to observe and manually adjust the adjustment structure.

[0031] Furthermore, the adjustment structure includes an adjustment rod 19, a connecting rod 20, and a size detection rod 21. The adjustment rod 19 is slidably installed in the square groove 18, and the connecting rod 20 is rotatably installed on the adjustment rod 19.

The surface of the adjustment rod 19 is provided with scales or markings to facilitate operators to accurately control its sliding distance and accurately adjust the position of the size detection rods 21. During the process of connecting the adjustment rod 19 and the size detection rods 21, the rotating connection method of the connecting rod 20 allows the size detection rods 21 to flexibly adjust their angles in multiple directions, which can adapt to the complex surface shape of the insulator.

[0054] Working principle: Before the inspection begins, the insulator 7 to be inspected is installed on the insulator fixing structure. This structure consists of a support plate 4, a rotating shaft 5, and a first motor 6. The first motor 6 is started, and its output shaft drives the rotating shaft 5, which is fixedly connected to it, to rotate. Since multiple sets of linearly arranged insulators 7 are fixed to the outer surface of the rotating shaft 5, the insulators 7 rotate synchronously with the rotating shaft 5, ensuring that the insulator rotates continuously during the inspection process. This ensures that all parts can be detected, avoiding blind spots and guaranteeing the possibility of comprehensive dimensional inspection of the insulator. Once the insulator 7 starts rotating, the rotating structure begins to function. The rotating structure includes a fixing plate 10, a second motor 11, and a lead screw 12. The second motor 11 is started, and its output shaft drives the rotating shaft 5 to rotate. The output shaft drives the lead screw 12 to rotate. The lead screw 12 and the slide plate 13 are connected by a threaded hole on the side of the slide plate. The rotation of the lead screw 12 drives the slide plate 13 to slide in the groove 9 of the limit block 8. The roller 15 in the mounting groove 14 at the bottom of the slide plate 13 rolls in the groove 9, reducing the friction when the slide plate 13 moves and making the sliding smoother. The movement of the slide plate 13 provides a horizontal displacement basis for the subsequent detection box 17 to reach different detection positions, allowing the detection fixture to detect insulators at different positions. After the slide plate 13 moves to the appropriate position, the moving structure starts to work. The moving structure consists of an electric telescopic rod 16 and a detection box 17. The electric telescopic rod 16 is activated and extends or retracts according to the detection requirements, driving the detection box 17 at the bottom to move vertically. As the test box 17 moves upward, it approaches or moves away from the rotating insulator 7, adjusting to a suitable height for testing. This prepares the box for accurate measurement of the insulator's dimensions at different heights. Once the test box 17 is close to the insulator, the adjustment mechanism begins operation. This mechanism includes an adjustment rod 19, a connecting rod 20, and dimension detection rods 21. Through manual or automatic control, the adjustment rod 19 slides within the square groove 18 on the side of the test box 17. This sliding motion of the adjustment rod 19 causes the connecting rod 20, which is rotatably connected to it, to move. A set of dimension detection rods 21, rotatably mounted on both sides of the bottom of the connecting rod 20, also changes angle and position accordingly. Since the dimension detection rods 21 are L-shaped, part of each rod passes through both sides of the test box 17. By adjusting the position of the dimension detection rods 21, they can... The device closely fits or aligns with the complex shape and special parts of the insulator, enabling precise dimensional measurement. Throughout the testing process, the various devices work in close and orderly coordination. The first motor 6 drives the insulator 7 to rotate, providing a basis for all-around testing. The rotating structure drives the sliding plate 13 to move horizontally, while the moving structure drives the testing box 17 to move vertically. Together, they allow for multi-position adjustment of the testing box 17 in space. The adjustment structure performs fine-tuning and adaptation for different parts of the insulator. This collaborative working method achieves efficient and accurate dimensional testing of insulators. Compared with traditional testing methods, it greatly improves testing efficiency and accuracy while reducing errors caused by manual operation, ensuring that only insulators with qualified dimensions enter the market or are put into use.This ensured the safe and stable operation of the power system.
