Description

Technical Field

[0001] This utility model relates to the field of insulator testing, and in particular to a device for testing the mechanical strength of disc-type suspension glass insulators. Background Technology

[0002] Disc-type suspension glass insulators are suspension insulators made of glass material, typically composed of glass components and metal fittings, bonded together with adhesive or mechanically clamped. These insulators are primarily used to support conductors and provide electrical insulation, and are commonly found in transmission lines. Disc-type suspension glass insulators are widely used in AC overhead transmission lines, especially in applications requiring high mechanical strength and good electrical performance. Their superior weather resistance and corrosion resistance make them perform well in various environmental conditions. However, disc-type suspension glass insulators are brittle materials with relatively weak mechanical strength; therefore, mechanical strength testing is usually required to ensure the quality of the finished glass insulators.

[0003] For example, patent number (CN206523378U) discloses a device for testing the shear resistance strength of the head of a disc suspension insulator. This device includes a clamp, a pendulum, a position detection mechanism, a height adjustment mechanism, and a support mechanism. The clamp is used to clamp the insulator to be tested. The height adjustment mechanism is positioned above the clamp and is adjustablely connected to the support mechanism along the height direction. The pendulum rod is connected to the height adjustment mechanism, and the weight in the pendulum applies an impact force to the insulator. The position detection mechanism is connected to the height adjustment mechanism and is used to detect the position of the pendulum. This invention allows the device to test the shear resistance strength of various types of disc suspension insulators with high data accuracy. It helps designers improve their understanding of the shear resistance performance of the heads of various disc suspension insulators, enabling them to further optimize the design by considering the shear strength, and simultaneously improving the safety performance of the disc suspension insulator.

[0004] Currently, when the disc suspension glass insulator mechanical strength testing device is in operation, due to certain limitations in the protective structure of the testing device, glass insulator fragments may fly in all directions, which is not conducive to improving the safety of the testing device. Utility Model Content

[0005] To overcome the problem that glass insulator fragments may fly around during the operation of the glass insulator mechanical strength testing device, which is detrimental to the safety of the testing device.

[0006] The technical solution of this utility model is as follows: a mechanical strength testing device for disc-shaped suspension glass insulators, including a testing platform and a testing instrument. A telescopic cylinder is fixedly installed inside the testing instrument, and a connecting rod is fixedly installed at the output end of the telescopic cylinder. A connecting plate is fixedly installed on the upper side of the connecting rod, and a strength testing head is provided at the lower end of the connecting rod. A connecting sleeve is fixedly installed on the side of the lower end of the connecting plate, and a return spring is fixedly installed inside the connecting sleeve. A sliding block is fixedly installed at the lower end of the return spring, and a sliding rod is fixedly installed at the lower end of the sliding block. A protective cover is fixedly installed at the lower end of the sliding rod extending to the outside of the connecting sleeve. A testing groove is fixedly installed at the upper end of the testing platform, and a collection cavity is provided inside the testing platform. A collection box is provided inside the collection cavity, and a connecting plate is fixedly installed at the front end of the collection box extending to the outside of the collection cavity. A handle is fixedly installed at the front end of the connecting plate.

[0007] Preferably, the inner side of the testing slot has a trapezoidal structure to accommodate glass insulators. An electric telescopic rod can drive a positioning clamp to fit the insulator and position it. The testing instrument can control the operation of the equipment and facilitate the observation of testing data. A telescopic cylinder can drive a connecting rod to move downwards, facilitating the strength testing head to press the insulator for strength testing. A protective cover can fit snugly over the testing slot, effectively preventing any flying glass insulator fragments. The protective cover is made of transparent material, allowing for easy observation of the testing process. A sliding rod can automatically adjust the protective cover in conjunction with a reset spring. The testing slot and the collection cavity are interconnected, allowing fragments to slide directly into the collection box, thus achieving automatic collection of fragments generated during strength testing.

[0008] Preferably, the connecting sleeves are arranged in a ring array, the surface of the connecting rod is slidably connected to the protective cover, and the testing instrument is fixedly connected to the testing platform.

[0009] Preferably, the sliding block is slidably connected to the connecting sleeve, and the connecting sleeve is slidably connected to the sliding rod.

[0010] Preferably, electric telescopic rods are fixedly installed at both ends of the detection slot, and the output end of the electric telescopic rod extends into the interior of the detection slot and is fixedly installed with a positioning clamp.

[0011] Preferably, the output end of the electric telescopic rod is slidably connected to the detection slot, and the protective cover is adapted to the detection slot.

[0012] As a preferred option, the detection slot is designed with a trapezoidal structure, and the detection slot is connected to the collection cavity.

[0013] Preferably, the collection box is slidably connected to the collection cavity, and the connecting plate is snapped into the detection stage.

[0014] The beneficial effects of this utility model are:

[0015] This disc-shaped suspension glass insulator mechanical strength testing device places the glass insulator into the testing slot. An electric telescopic rod drives a positioning clamp to position and restrict the insulator, preventing it from swaying or shifting during testing. The testing instrument controls the strength testing head to press the insulator for strength testing, simultaneously moving the protective cover to cover the testing slot. The protective cover is slidably connected to a connecting rod, allowing for flexible adjustment with a return spring. This effectively prevents any flying glass insulator fragments from injuring workers, improving the safety of the testing device. The protective cover provides both safety and allows for the rebound of fragments. It connects to the testing slot and collection cavity, facilitating the direct sliding of fragments into the collection box for automatic collection of fragments generated during strength testing, thus improving the convenience of subsequent cleaning.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a mechanical strength testing device for disc-shaped suspension glass insulators, including a testing platform 1 and a testing instrument 2. A telescopic cylinder 4 is fixedly installed inside the testing instrument 2, and a connecting rod 5 is fixedly installed at the output end of the telescopic cylinder 4. A connecting plate 6 is fixedly installed on the upper side of the surface of the connecting rod 5, and a strength testing head 7 is provided at the lower end of the connecting rod 5. A connecting sleeve 8 is fixedly installed on the side of the lower end of the connecting plate 6, and a return spring 9 is fixedly installed inside the connecting sleeve 8. A sliding block 10 is fixedly installed at the lower end of the return spring 9, and a sliding rod 11 is fixedly installed at the lower end of the sliding block 10. A protective cover 12 is fixedly installed at the lower end of the sliding rod 11 extending to the outside of the connecting sleeve 8. A testing groove 13 is fixedly installed at the upper end of the testing platform 1, and a collection cavity 14 is provided inside the testing platform 1 for collecting... A collection box 15 is installed inside the cavity 14. A connecting plate 16 is fixedly installed on the front end of the collection box 15 to the outside of the collection cavity 14. A handle 17 is fixedly installed on the front end of the connecting plate 16. The glass insulator is placed in the test groove 13. The positioning clamp 3 is positioned and restricted by the electric telescopic rod 18. The connecting rod 5 is moved downward by the telescopic cylinder 4 to facilitate the strength test head 7 to perform strength test. At the same time, the protective cover 12 fits and covers the test groove 13, which can effectively block the possible flying glass insulator fragments. When the protective cover 12 intercepts the flying fragments, the fragments will bounce back and fall back into the test groove 13. The test groove 13 is connected to the collection cavity 14, which makes it convenient for the fragments to slide directly into the collection box 15, avoiding the situation where the fragments are scattered everywhere and are inconvenient to clean.

[0024] Please see Figures 1-4 In this embodiment, the connecting sleeves 8 are arranged in a ring array. The surface of the connecting rod 5 is slidably connected to the protective cover 12. The testing instrument 2 is fixedly connected to the testing platform 1. The sliding block 10 is slidably connected to the connecting sleeve 8. The connecting sleeve 8 is slidably connected to the sliding rod 11. Electric telescopic rods 18 are fixedly installed at both ends of the testing groove 13. The output end of the electric telescopic rod 18 extends into the interior of the testing groove 13 and is fixedly installed with a positioning clamp 3. The output end of the electric telescopic rod 18 is slidably connected to the testing groove 13. The protective cover 12 and the testing groove 13 are mutually adapted to each other. The glass insulator is placed in the testing groove 13. The electric telescopic rod 18 drives the positioning clamp 3 to adhere to the glass insulator and position and restrict it. The telescopic cylinder 4 controlled by the testing instrument 2 drives the connecting rod 5 to move downward, so that the strength testing head 7 can press the insulator to perform strength testing. At the same time, the protective cover 12 adheres to and covers the testing groove 13, which can effectively prevent the possible splashing glass insulator fragments and avoid injury to the staff, which is conducive to improving the safety of the testing device.

[0025] Please see Figure 1 , Figure 4 and Figure 5In this embodiment, the detection groove 13 is designed with a trapezoidal structure. The detection groove 13 is connected to the collection cavity 14. The collection box 15 is slidably connected to the collection cavity 14. The connecting plate 16 is engaged with the detection platform 1. When the protective cover 12 intercepts the splashing debris, the debris will bounce back and fall back into the detection groove 13. With the detection groove 13 and the collection cavity 14 connected to each other, the debris can slide directly into the collection box 15, realizing the automatic collection of debris generated by the intensity test, which is beneficial to improving the convenience of subsequent cleaning work of the detection device.

[0026] During operation, the glass insulator is placed in the testing slot 13. The electric telescopic rod 18 drives the positioning clamp 3 to adhere to the glass insulator and restrict its position. The telescopic cylinder 4, controlled by the testing instrument 2, moves the connecting rod 5 downward, facilitating the strength testing head 7 to press the insulator for strength testing. Simultaneously, the protective cover 12 adheres to and covers the testing slot 13. The protective cover 12 is slidably connected to the connecting rod 5, and the sliding rod 11 transmits the pressing force to the return spring 9, allowing the protective cover 12 to be flexibly adjusted according to the processing depth and always adhere to the testing slot 13. This effectively prevents any flying glass insulator fragments from injuring the workers. When the protective cover 12 intercepts flying fragments, the fragments bounce back and fall back into the testing slot 13. The testing slot 13 is connected to the collection cavity 14, allowing the fragments to slide directly into the collection box 15, thus achieving automatic collection of fragments generated during strength testing.

[0027] Through the above steps, the glass insulator is placed in the test groove 13, and the positioning clamp 3 is positioned and restricted by the electric telescopic rod 18. The connecting rod 5 is moved downward by the telescopic cylinder 4, which facilitates the strength testing head 7 to perform strength testing. At the same time, the protective cover 12 fits snugly to cover the test groove 13, which can effectively prevent the possible splashing of glass insulator fragments. This solves the problem that glass insulator fragments may splash around when the glass insulator mechanical strength testing device is working, which is not conducive to improving the safety of the testing device.
