Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of load testing, specifically to a load testing device for insulator assemblies. Background Technology
[0002] In power systems, insulators are extremely important components. Their main function is to maintain the insulation between conductors and electrical equipment such as ground wires or towers, while supporting and fixing power lines. To ensure their stable operation in complex environments, insulators need to undergo torsional and other stress tests after production to examine their mechanical properties.
[0003] For example, Chinese utility model patent CN101581645A discloses a testing machine, specifically relating to a testing machine for detecting the bending moment and torque of insulators. The technical problem this invention aims to solve is to provide an insulator bending and torsion testing machine that allows for convenient testing and provides accurate and intuitive test data. The machine includes a base and a column fixed to the base. A slider is mounted on the column, and a bending moment device and a torque device are mounted on the base. Sensors are mounted on both the bending moment and torque devices, and these sensors are connected to a computer via a data acquisition card. The bending moment and torque devices are used to quickly fix and test the insulator, and the sensors transmit the data to the computer to generate data tables or graphs, facilitating the accurate acquisition of test data.
[0004] However, since a certain torque force needs to be generated on the insulator during the load test, and since the insulator to be tested is not of a fixed length, the fixation of the insulator becomes particularly important. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides an insulator assembly load test device that facilitates the fixing of insulators of different lengths, improves the fixing effect of the device on the insulators, improves the stability of the insulators during the testing process, and enhances the practicality of the device.
[0006] This utility model discloses an insulator assembly load testing device, comprising a workbench, a support plate slidably mounted on the top of the workbench via an upward lifting mechanism, a first fixing plate horizontally fixedly mounted in the middle area of the support plate, a plurality of fixing mechanisms for fixing the insulator on the first fixing plate, a second fixing plate slidably mounted on the top of the workbench via a limiting mechanism, a fixing mechanism corresponding to the bottom end of the first fixing plate on the top of the second fixing plate, and a power mechanism on the top of the workbench; the fixing mechanism includes a first screw, which is longitudinally screwed to the first fixing plate, a clamping plate rotatably mounted on the bottom end of the first screw, a fixing ring fixedly mounted on the bottom end of the first fixing plate via two connecting plates, the top area of the fixing ring being screwed to the first screw, the clamping plate being located in the inner top area of the fixing ring, a limiting groove being formed at the bottom end of the fixing ring, and a sealing plate being sealed at one end of the fixing ring; The power mechanism includes a fifth support, which is fixedly mounted on the top of the workbench. A cylinder is fixedly mounted on the top of the fifth support, and a push plate is fixedly mounted on the output end of the cylinder. A connecting block is fixedly mounted parallel to the output end of the push plate. A fixing block is fixedly mounted on the top of the second fixing plate. The connecting block and the fixing block are in contact. This insulator assembly load testing device adjusts the height of the support plate and the first fixing plate through a lifting mechanism. By judging the length of the insulator, the distance between the fixing rings on the first fixing plate and the second fixing plate is adjusted. The top area of the insulator passes through the limiting groove at the bottom of the fixing ring and is initially fixed through the fixing ring. Simultaneously, the top area of the insulator passes through the second fixing ring. The limiting groove at the top of the fixing ring on the top of the fixing plate allows the first screws on the first and second fixing plates to rotate synchronously. This synchronously drives the clamping plates on the first screws to clamp and fix the top and bottom of the insulator. The cylinder is activated, outputting power from one end, which synchronously drives the push plate and connecting block to move the fixing block fixed at the top of the second fixing plate. Simultaneously, the movement of the fixing block causes the insulators fixed on the second and second fixing plates to stretch. This facilitates fixing insulators of different lengths, improves the device's fixing effect on the insulators, enhances the stability of the insulators during testing, and improves practicality.
[0007] Preferably, two trays are symmetrically fixedly installed on the top of the workbench, and a limiting plate is fixedly installed on the top of the two trays. The bottom end of the push plate is slidably connected to the top of the limiting plate. The push plate slides on the top of the limiting plate, thereby effectively limiting the push plate and the connecting block that are sliding.
[0008] Preferably, a first bracket is fixedly installed on the outer wall of the output end of the cylinder, and the outer wall of the first bracket is fixedly connected to the outer wall of the push plate at an angle by two second brackets. The installation of the first bracket and the second bracket facilitates the synchronous power output to the outer wall of the push plate through the cylinder.
[0009] Preferably, the limiting mechanism includes two third supports, which are symmetrically fixedly installed on the top of the workbench. Two guide plates are symmetrically fixedly installed on the outer side wall of the second fixed plate. A bonding plate is fixedly installed on the outer side wall of each third support. The bonding plate and the guide plate slide against each other. By sliding the guide plate on the second fixed plate against the bonding plate on the third support, the sliding operation of the second fixed plate is effectively limited.
[0010] Preferably, multiple wheels are fixedly installed around the bottom of the second fixed plate, which facilitates the support and movement of the bottom of the second fixed plate.
[0011] Preferably, the lifting mechanism includes two support rods, which are symmetrically fixedly installed on the top of the workbench. Each support rod has a groove at its top, and a slider is slidably installed on each groove. The two sliders are fixedly connected by a fixed bracket, and the two fixed brackets are fixedly connected by a support plate. Each fixed bracket has a screw threaded on it longitudinally, and the bottom end of each screw thread is rotatably connected to the top of the workbench. Rotating the screw thread simultaneously drives the fixed bracket and the slider to slide on the groove on the support rod. The movement of the fixed bracket simultaneously drives the support plate and the first fixed plate to move. The distance between the fixed ring on the first fixed plate and the fixed ring on the second fixed plate can be adjusted to facilitate the fixing of insulators of different lengths.
[0012] Preferably, the support plate and the first fixed plate are fixedly connected by multiple 30s. By installing 30s, the stability of the connection between the support plate and the first fixed plate during operation is improved.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This insulator assembly load testing device adjusts the height of the support plate and the first fixed plate through a lifting mechanism. By judging the length of the insulator, the distance between the fixed rings on the first and second fixed plates is adjusted. The top area of the insulator passes through the limiting groove at the bottom of the fixed ring and is initially fixed through the fixed ring. Simultaneously, the top area of the insulator passes through the limiting groove at the top of the fixed ring on the top of the second fixed plate. The first screws on the first and second fixed plates rotate synchronously, thereby driving the clamping plates on the first screws to clamp and fix the top and bottom of the insulator. The cylinder is activated, and power is output through one end of the cylinder, thereby driving the push plate and connecting block to move the fixed block fixed at the top of the second fixed plate. As the fixed block moves, the insulators fixed on the second and second fixed plates are stretched simultaneously. This facilitates the fixing of insulators of different lengths, improves the fixing effect of the device on the insulator, improves the stability of the insulator during the test, and improves practicality.

Detailed Implementation
[0016] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.
[0017] The insulator assembly load testing device of this utility model includes a workbench 1. A support plate 2 is slidably installed on the top of the workbench 1 via an upward lifting mechanism. A first fixing plate 3 is horizontally fixed in the middle area of the support plate 2. The first fixing plate 3 is provided with multiple fixing mechanisms for fixing the insulator. A second fixing plate 10 is slidably installed on the top of the workbench 1 via a limiting mechanism. The top of the second fixing plate 10 is provided with a fixing mechanism corresponding to the bottom of the first fixing plate 3. A power mechanism is provided on the top of the workbench 1. The fixing mechanism includes a first screw 4, which is longitudinally screwed to the first fixing plate 3. A clamping plate 5 is rotatably installed on the bottom of the first screw 4. A fixing ring 7 is fixedly installed on the bottom of the first fixing plate 3 via two connecting plates 6. The top area of the fixing ring 7 is screwed to the first screw 4. The clamping plate 5 is located in the inner top area of the fixing ring 7. A limiting groove 8 is opened at the bottom of the fixing ring 7. A sealing plate 9 is sealed at one end of the fixing ring 7. The power mechanism includes a fifth bracket 11, which is fixedly installed on the top of the workbench 1. A cylinder 12 is fixedly installed on the top of the fifth bracket 11. A push plate 13 is fixedly installed on the output end of the cylinder 12. A connecting block 14 is fixedly installed parallel to the output end of the push plate 13. A fixing block 15 is fixedly installed on the top of the second fixing plate 10. The connecting block 14 and the fixing block 15 are in contact. Two support plates 16 are symmetrically fixedly installed on the top of the workbench 1. Limiting plates 17 are fixedly installed on the top of the two support plates 16. The bottom end of the push plate 13 is slidably connected to the top end of the limiting plate 17. A first bracket 19 is fixedly installed on the outer wall of the output end of the cylinder 12. The outer wall of the first bracket 19 is obliquely fixed to the outer wall of the push plate 13 through two second brackets 20. The limiting mechanism includes two third brackets 21, which are symmetrically fixed. Two guide plates 23 are symmetrically fixedly installed on the outer side wall of the second fixed plate 10, which is installed on the top of the workbench 1. A fitting plate 22 is fixedly installed on the outer side wall of each third bracket 21. The fitting plate 22 and the guide plate 23 are slidably fitted together. Multiple wheels 24 are fixedly installed around the bottom of the second fixed plate 10. The lifting mechanism includes two support rods 25, which are symmetrically fixedly installed on the top of the workbench 1. Each support rod 25 has a groove 26 at its top. A slider 27 is slidably installed on each groove 26. The two sliders 27 are fixedly connected by a fixed bracket 28. The two fixed brackets 28 are fixedly connected by a support plate 2. Each fixed bracket 28 is longitudinally screwed with a 29. The bottom of each 29 is rotatably connected to the top of the workbench 1. The support plate 2 and the first fixed plate 3 are fixedly connected by multiple 30s.
[0018] like Figures 1 to 5As shown, the insulator assembly load testing device of this utility model, during operation, rotates 29 while simultaneously driving the fixed bracket 28 and the slider 27 to slide on the groove 26 opened on the support rod 25. Simultaneously, the movement of the fixed bracket 28 drives the support plate 2 and the first fixed plate 3 to move. The distance between the fixed ring 7 on the first fixed plate 3 and the fixed ring 7 on the second fixed plate 10 is adjusted to facilitate fixing insulators of different lengths. By determining the length of the insulator, the distance between the fixed ring 7 on the first fixed plate 3 and the fixed ring 7 on the second fixed plate 10 is adjusted. The top area of the insulator passes through the limiting groove 8 at the bottom of the fixed ring 7 and is initially fixed through the fixed ring 7. Simultaneously, the top area of the insulator passes through the limiting groove 8 at the top of the fixed ring 7 on the top of the second fixed plate 10. The first screw 4 on the first fixed plate 3 and the second fixed plate 10 rotate synchronously. Then, the clamping plate 5 on the first screw 4 is driven to clamp and fix the top and bottom of the insulator. The cylinder 12 is started, and power is output through one end of the cylinder 12. This drives the push plate 13 and the connecting block 14 to move the fixing block 15 fixed at the top of the second fixing plate 10. The installation of the first bracket 19 and the second bracket 20 facilitates the synchronous power output to the outer wall of the push plate 13 through the cylinder 12. The push plate 13 slides on the top of the limiting plate 17, thus effectively limiting the sliding push plate 13 and the connecting block 14. As the fixing block 15 moves, it simultaneously drives the second fixing plate 10 and the insulator fixed on the second fixing plate 10 to stretch. The guide plate 23 on the second fixing plate 10 slides and adheres to the bonding plate 22 on the third bracket 21, thus effectively limiting the sliding second fixing plate 10. This facilitates the fixing of insulators of different lengths.
