Description

Technical Field

[0001] This invention relates to the field of protective fittings testing technology, and more specifically, to a vibration testing device for a vibration damper used in transmission lines that is designed to prevent loosening and slippage. Background Technology

[0002] Vibration dampers are protective hardware installed on conductors to suppress or reduce aerodynamic vibrations. They are fixed to overhead lines by clamps. When the conductor vibrates, the damper moves up and down, causing internal friction in the steel strands due to inertia, which, combined with air damping, dissipates the vibrational energy. In overhead transmission lines, the threat to conductors is often not sudden storms, but a persistent attack that is almost imperceptible to the naked eye—aerodynamic vibration. This high-frequency, low-amplitude continuous vibration, after prolonged cycles, is enough to wear fatigue cracks into the conductor strands at the suspension clamp outlet. Aerodynamic vibration is one of the main causes of conductor fatigue, strand breakage, wear, and even line breakage. As a core protective hardware for suppressing aerodynamic vibrations, the vibration damper dissipates the conductor's vibrational energy through its weighted vibration.

[0003] Vibration dampers are typically secured to conductors using clamps, and their long-term reliability directly determines the safe operation level of the line. However, after long-term operation, vibration dampers are prone to problems such as loosening of clamp bolts and slippage of the clamps along the conductor's axial or circumferential direction. Once the vibration damper loosens or slips, its natural frequency will deviate from the design value, significantly reducing its vibration damping performance and even becoming a source of fatigue fracture risk. To address this, the industry has developed various anti-loosening and anti-slip vibration dampers for transmission lines, such as those employing wedge-shaped self-locking structures, eccentric clamping, pre-installed anti-loosening adhesive, or double-locking bolts. To ensure that the vibration reduction performance, anti-loosening life, and anti-slip capability of these new vibration dampers meet engineering requirements under different operating conditions, standardized vibration tests must be conducted to verify their anti-loosening and anti-slip performance. Summary of the Invention

[0004] The purpose of this invention is to provide a vibration testing device for a transmission line anti-loosening and anti-slip type vibration hammer to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides a vibration testing device for a transmission line with anti-loosening and anti-slip type vibration damper, comprising: a test conductor and a clamping platform, wherein a vibration damper is provided on the test conductor, and both ends of the test conductor are respectively fixed on the clamping platform, and an excitation mechanism is installed on the clamping platform; After the two ends of the test lead are inserted into the clamping platform, the clamping platform can clamp them tightly. The clamping platform can adjust the tension of the test conductor to change the sag of the test conductor; After the excitation mechanism is activated, it causes the test lead to vibrate at a gradually increasing high frequency and low amplitude. At this time, the hammer head of the anti-vibration hammer swings in the opposite direction to the test lead.

[0006] Furthermore, the clamping platform includes: The platform is fixed; A carrier plate, which is linearly and movably mounted on the platform; A curved tubular head, which is mounted on the carrier plate; A cylinder is mounted on the platform, and the output shaft of the cylinder is connected to the platform. The clamp has at least one flexible part on the horizontal portion of the curved tubular head, and the clamp is installed on the curved tubular head and corresponds to the flexible part of the curved tubular head.

[0007] Furthermore, the excitation mechanism includes: An extended panel is installed at the inlet of the curved tubular head; The first exciter is mounted on the widened panel.

[0008] Furthermore, the excitation mechanism also includes: A support frame, which is mounted on the platform; A circular shaft, which is rotatably mounted on the upright frame; The motor is mounted on the upright frame; Two gears are respectively mounted on the round shaft and the output shaft of the motor, and the two gears mesh with each other; An extension arm, which is connected to the circular shaft; A covering plate, wherein the covering plate is connected to the end of the outrigger arm; A second vibrator is mounted on the back of the cover plate; After the motor is started, the outrigger and the covering plate are swung toward the test lead, and the covering plate partially covers the test lead.

[0009] Furthermore, the extendable arm is divided into a front half arm and a rear half arm. The rear half arm is connected to the circular shaft, and the front half arm is connected to the covering plate. The front half arm and the rear half arm are rotatably connected by a rotating shaft. A swing motor is installed on the rear half-arm, and a swing arm is connected to the output end of the swing motor. The swing arm is connected to the root of the front half-arm. After the swing motor is started, the front half of the arm can swing horizontally relative to the test lead.

[0010] Furthermore, a hollow head is installed at the end of the patch plate, and several spray heads and infusion tubes are connected to the hollow head. The spray heads face the anti-vibration hammer, and the infusion tubes are fixed on the patch plate and connected to an external saline supply source.

[0011] Furthermore, a platform plate is connected to the bottom of the stage, and a rotating base is connected to the bottom of the platform plate.

[0012] Furthermore, a recessed groove is formed on the edge of the platform plate, and a transparent heat insulation cover is attached to the platform plate. The transparent heat insulation cover is inserted into the recessed groove. A transfer compartment is provided on the top of the transparent heat insulation cover. Several drainage channels are connected to the periphery of the transfer compartment. The drainage channels are aligned closely with the anti-vibration hammer. The transfer compartment is connected to an external integrated heating and cooling unit via a pipe.

[0013] Furthermore, a portion of the carrier plate is a disc spring, and the curved tubular head is connected to the disc spring.

[0014] Furthermore, the steel strand of the vibration damper is covered with a temperature-sensitive patch.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This anti-loosening and anti-slip type vibration test device for transmission lines uses a clamping platform to fix both ends of the test conductor and can adjust the tension of the test conductor to simulate the tension changes of the conductor during actual use, thus changing its sag. This closely approximates reality, simulating the actual installation conditions and usage of the conductor, fundamentally ensuring the standardization of the test and the validity of the results. Furthermore, by changing the tension of the simulated conductor, the anti-loosening and anti-slip performance of the vibration hammer is verified. The excitation mechanism excites the test conductor at different positions to varying degrees, thereby effectively simulating high-frequency, low-amplitude vibration. The vibration test can continue to simulate light wind vibration and also cause the test conductor to swing more significantly, thus strengthening the test method. In addition, it can simulate the effects of corrosive environments and large temperature fluctuations on the test conductor and vibration damper. Starting from the basic conditions, the test method is continuously deepened to fully restore the complex environment of the vibration damper in actual operation. Through comprehensive and in-depth testing, it is possible to test whether the anti-loosening and anti-slip type vibration damper for transmission lines will experience problems such as loosening of clamp bolts or slippage of clamps along the conductor axial or circumferential direction after long-term operation. The standardized vibration test can accurately verify its anti-loosening and anti-slip performance. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0020] like Figures 1-11 As shown, a vibration testing device for a transmission line anti-loosening and anti-slip type vibration hammer includes: a test conductor 1 and a clamping platform 2. An anti-vibration hammer 3 is installed on the test conductor 1. Both ends of the test conductor 1 are respectively fixed on a clamping platform 2. An excitation mechanism 4 is installed on the clamping platform 2. After the two ends of the test lead 1 are inserted into the clamping platform 2, the clamping platform 2 can clamp it tightly; The clamping platform 2 can adjust the tension of the test lead 1 to change the sag of the test lead 1; After the vibration mechanism 4 is activated, it causes the test lead 1 to undergo gradually increasing high-frequency, low-amplitude vibration. At this time, the hammer head of the anti-vibration hammer 3 swings in the opposite direction to the test lead 1, fixing both ends of the test lead 1 through the clamping platform 2. The tension of the test lead 1 can be adjusted to simulate the tension changes of the lead during actual use, thus changing its sag. This closely approximates reality, simulating the actual installation conditions and usage of the lead, fundamentally ensuring the standardization of the test and the validity of the results. Furthermore, by changing the tension of the simulated lead, the anti-loosening and anti-slip performance of the anti-vibration hammer 3 is verified. The vibration mechanism 4 vibrates the test lead 1 to different degrees from different positions. This effectively simulates high-frequency, low-amplitude continuous micro-wind vibration and can also induce a large-amplitude swing in the test conductor 1, thus enhancing the testing method. In addition, it can simulate the effects of corrosive environments and large-amplitude temperature changes on the test conductor 1 and the vibration damper 3. Starting from the basic conditions, the testing method is continuously deepened to fully restore the complex environment of the vibration damper 3 in actual operation. Through comprehensive and in-depth testing, it is possible to test whether the anti-loosening and anti-slip type vibration damper 3 for transmission lines will experience problems such as loosening of the clamp bolts or slippage of the clamp along the axial or circumferential direction of the conductor after long-term operation. The standardized vibration test accurately verifies its anti-loosening and anti-slip performance.

[0021] Optionally, the clamping platform 2 includes: Platform 21, platform 21 is fixed; Carrier plate 22 is linearly and movably mounted on stage 21; The curved tubular head 23 is mounted on the carrier plate 22; Cylinder 24 is mounted on the platform 21, and the output shaft of cylinder 24 is connected to the carrier plate 22. At least one part of the horizontal portion of the clamp 25 and the curved tubular head 23 is in a flexible state. The clamp 25 is installed on the curved tubular head 23 and corresponds to the flexible portion of the curved tubular head 23. During the test, both ends of the test lead 1 are inserted into the curved tubular heads 23 on both sides, and then the clamp 25 is gradually tightened to clamp the test lead 1 until it is firmly clamped, simulating the actual installation of the lead. Then, the vibration damper 3 is installed in the corresponding position. Under normal conditions, the test lead 1 sags significantly, with a large sag and is relatively loose. The starting cylinder 24 can pull the carrier plate 22 backward, thereby gradually straightening the test lead 1 from both sides and applying running tension to the test lead 1, simulating the running stress of the overhead conductor, so that the test conditions can be closer to the actual installation conditions and usage, fundamentally ensuring the standardization of the test and the validity of the results. Furthermore, the anti-loosening and anti-slip performance of the vibration damper 3 is tested by changing the tension of the simulated lead.

[0022] Optionally, the excitation mechanism 4 includes: Widening panel 41 is installed at the inlet of curved tubular head 23; The first exciter 42 is mounted on the widened panel 41. When the first exciter 42 is activated, the excitation force can be transmitted to both ends of the test conductor 1 through the widened panel 41 and the curved tubular head 23 and then transmitted to the center, thereby causing the test conductor 1 to generate high-frequency, low-amplitude continuous vibration, simulating a light breeze vibration, and thus testing the anti-loosening and anti-slip performance of the anti-vibration hammer 3. The test will determine whether the anti-loosening and anti-slip function of the transmission line anti-vibration hammer 3 will cause problems such as loosening of the clamp bolts or slippage of the clamp along the axial or circumferential direction of the conductor after long-term operation. The end of the test conductor 1 is inserted into the curved tubular head 23, so that the test conductor 1 can receive the excitation force more directly over a larger area, thereby ensuring the overall vibration effect of the test conductor 1.

[0023] Optionally, the excitation mechanism 4 also includes: Frame 43 is mounted on platform 21; A circular shaft 44 is rotatably mounted on a vertical frame 43. Motor 45, motor 45 is mounted on the support frame 43; Gear 46, two gears 46 are respectively mounted on the round shaft 44 and the output shaft of the motor 45, and the two gears 46 mesh; Extendable arm 47, which is connected to round shaft 44; Cover plate 48, which is connected to the end of the outrigger 47; The second exciter 49 is mounted on the back of the cover plate 48; After the motor 45 is started, the extended arm 47 and the covering plate 48 are swung toward the test lead 1. The covering plate 48 partially covers the test lead 1. After the first vibrator 42 continuously vibrates the test lead 1, the motor 45 is started. Through the meshing transmission of the two gears 46, the round shaft 44 is driven to rotate, turning the extended arm 47 toward the test lead 1 until the covering plate 48 is attached to the test lead 1 and partially covers it. Then the second vibrator 49 is started. The second vibrator 49, based on the first vibrator 42, transmits the excitation force to the test lead 1 again at a position closer to the anti-vibration hammer 3, strengthening the vibration of the test lead 1. This deepens the test method, increases the test intensity, and ensures that within a limited test time, an effective test can be conducted on whether the anti-vibration hammer 3 will experience loosening of the clamp bolts or slippage of the clamp along the axial or circumferential direction of the lead after long-term operation. This ensures that its anti-loosening and anti-slip performance can be accurately tested.

[0024] Optionally, the extendable arm 47 is divided into a front half arm 471 and a rear half arm 472. The rear half arm 472 is connected to the round shaft 44, and the front half arm 471 is connected to the cover plate 48. The front half arm 471 and the rear half arm 472 are rotatably connected by a rotating shaft. A swing motor 491 is installed on the rear half arm 472, and a swing arm 492 is connected to the output end of the swing motor 491. The swing arm 492 is connected to the root of the front half arm 471. After starting the swing motor 491, the front half arm 471 can swing horizontally relative to the test conductor 1. At the same time as the vibration is activated, the swing motor 491 is started, so that the front half arm 471 swings back and forth regularly. Thus, the test conductor 1 is moved back and forth by the covering plate 48 that is partially wrapped on the test conductor 1. On the basis of the high frequency and low amplitude vibration of the test conductor 1, it is made to swing with a large amplitude to simulate its swaying situation in windy weather. This deepens the test method and fully restores the complex environment of the anti-vibration hammer 3 in actual operation as much as possible. Through comprehensive and in-depth testing, it is possible to test whether the anti-loosening and anti-slip type anti-vibration hammer 3 for transmission lines will have problems such as loosening of the clamp bolts or slippage of the clamp along the conductor axial or circumferential direction after long-term operation. The anti-loosening and anti-slip performance is accurately verified by standardized vibration test.

[0025] Optionally, a hollow head 5 is installed at the end of the covering plate 48. Several spray heads 6 and an infusion tube 7 are connected to the hollow head 5. The spray heads 6 face the anti-vibration hammer 3. The infusion tube 7 is fixed to the covering plate 48 and connected to an external brine supply source. When vibrating, the external brine supply source is turned on to deliver brine into the hollow head 5. Then, the spray heads 6 spray the brine in the form of salt mist towards the anti-vibration hammer 3, so that the anti-vibration hammer 3 is covered with corrosive salt mist. The salt mist will corrode the contact surface. The volume expansion of the corrosion products will temporarily cause jamming. However, with vibration, the oxide layer and corrosion products will break and be lost, and the gap will suddenly increase, increasing the risk of loosening. This simulates the use of the anti-vibration hammer 3 in a corrosive environment and tests whether the anti-vibration hammer 3 can maintain its anti-loosening and anti-slip performance for a long time under vibration, swing and corrosive environment.

[0026] Optionally, the bottom of the stage 21 is connected to a platform plate 8, and the bottom of the platform plate 8 is connected to a rotating base 9. Multiple sets of clamping platforms 2 and vibration excitation mechanisms 4 are arranged on the platform plate 8, allowing multiple test leads 1 to be laid out to simultaneously test multiple vibration dampers 3, such as... Figure 6 As shown, multiple vibration dampers 3 are tested simultaneously, and the excitation forces can interact and cross-influence each other, further increasing the complexity of the test environment and fully replicating the complex environment of the vibration damper 3 during actual operation. With the support of the rotating base 9, the platform plate 8 can rotate. When installing the vibration damper 3, the position of the test lead 1 can be changed one by one by rotating the platform plate 8. After the vibration damper 3 is installed on the current test lead 1, the next test lead 1 can be turned over, making the preparation work more convenient.

[0027] Optionally, a recessed groove 10 is opened on the edge of the platform plate 8, and a transparent heat insulation cover 11 is attached to the platform plate 8. The transparent heat insulation cover 11 is inserted into the recessed groove 10. A transfer compartment 12 is provided on the top of the transparent heat insulation cover 11. Several drainage channels 13 are connected to the periphery of the transfer compartment 12. The drainage channels 13 are aligned closely with the anti-vibration hammer 3. The transfer chamber 12 is connected to an external integrated cooling and heating unit via a connecting pipe. With the transparent insulation cover 11 installed, all the vibration dampers 3 and the test leads 1 are provided with a relatively isolated space. The external integrated cooling and heating unit is then activated, alternating between cooling and heating. After a period of cooling, it begins heating, and the hot and cold air is transported to the transparent insulation cover 11 through the transfer chamber 12 and several drainage channels 13, with a focus on discharging towards the vibration dampers 3. This achieves significant temperature fluctuations within the transparent insulation cover 11, causing the test leads 1 to expand and contract significantly with temperature changes, affecting the clamping force of the vibration damper 3's clamps. Meanwhile, when salt spray is sprayed onto the vibration damper 3, continuous cooling can cause ice formation on the vibration damper 3, especially inside the clamp and on the surface of the test conductor 1, thereby greatly reducing the coefficient of friction. This tests the clamping effect of the vibration damper 3, deepens the testing methods, and fully restores the complex environment of the vibration damper 3 in actual operation. Through comprehensive and in-depth testing, it tests whether the vibration damper 3 for transmission lines with anti-loosening and anti-slip effects will experience problems such as loosening of the clamp bolts or slippage of the clamp along the axial or circumferential direction of the conductor after long-term operation. The standardized vibration test accurately verifies its anti-loosening and anti-slip performance.

[0028] Optionally, a portion of the carrier plate 22 is a disc spring 221, and the curved tubular head 23 is connected to the disc spring 221. The disc spring 221 has a good vibration absorption effect. The disc spring 221 continuously absorbs the excitation force transmitted from the curved tubular head 23, preventing large-amplitude vibration of components such as the cylinder 24, effectively controlling the continued transmission of vibration force, and protecting the life of components such as the cylinder 24.

[0029] Optionally, the steel strand of the vibration damper 3 is covered with a temperature-sensitive patch. The temperature-sensitive patch changes color or shape when heated. When the conductor vibrates in a light breeze, the steel strand of the vibration damper 3 will bend repeatedly, causing friction between the strands and generating heat. At this time, the temperature-sensitive patch, which is extremely sensitive to temperature, is used to reflect the temperature change of the steel strand of the vibration damper 3. The vibration damping effect of the vibration damper 3 is tested by observing the state of the temperature-sensitive patch, and it is determined whether the vibration damper 3 has produced a positive and effective anti-loosening and anti-slip effect.

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
