Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, specifically to a device for testing the mechanical strength of insulator materials. Background Technology

[0002] Insulators are indispensable key insulating components in power systems and are widely used in power facilities such as transmission lines and substations. They are mainly used to support conductors, fix electrical equipment, and achieve electrical insulation between conductors and grounding bodies. At the same time, they must withstand various mechanical forces such as conductor tension, their own weight, wind load, and ice load. Their mechanical strength directly determines the safe and stable operation of the power system.

[0003] In existing technologies, the mechanical strength testing of new insulator materials is mainly concentrated in factory laboratories for new material research and development experiments, pre-mass production performance verification, and quality control during the production process. The existing testing devices for new insulator materials used in factory laboratories are mostly general-purpose large-scale testing equipment with complex structures, large size, and heavy weight. They are fixedly installed in dedicated testing areas of the laboratory, which not only occupies a lot of laboratory space, but also requires cumbersome equipment debugging and high professional skills from operators. Systematic training is required to master the operation procedures such as parameter setting, sample clamping, and data interpretation. Therefore, this invention provides a mechanical strength testing device for insulator materials. Summary of the Invention

[0004] The purpose of this invention is to provide a mechanical strength testing device for insulator materials to solve the problems mentioned in the background art.

[0005] The technical solution of this invention is: a mechanical strength testing device for insulator materials, comprising an outer mounting cylinder and a testing chassis. A bottom cylinder is fixedly connected to the inner side of the testing chassis, and four movable clamping blocks are fixedly connected to the outer side of the bottom cylinder. Four testing clamping slots are formed on the inner side of the testing chassis. Four inner fixing plates are fixedly connected to the inner side of the outer mounting cylinder. An inner positioning plate is slidably engaged with the inner side of each inner fixing plate. A fixing clamping block is fixedly connected to one end of each inner positioning plate. A testing mounting plate is rotatably connected between the fixing clamping block and the movable clamping block. The testing mounting plate contains an internal mounting plate... Equipped with a detection device, the detection end of which penetrates the detection mounting plate. A processing box is fixedly connected to the bottom of the detection device. A detection groove is formed on the top of the inner fixing plate. A positioning pin is fixedly connected to the top of the inner positioning plate. A displacement processing structure is fixedly connected to the top of the inner fixing plate. The positioning pin is slidably engaged in the detection groove and the displacement processing structure. Four clamping slots are formed on the inner side of the detection chassis. Two limiting slide shafts are fixedly connected in the clamping slots. A limiting slide plate is slidably engaged on the outer side of the limiting slide shaft. A compression spring is movably sleeved on the outer side of the shaft. A positioning clamping block is fixedly connected to one side of the limiting slide plate. A rotating inner shaft is fixedly connected to the inner side of the detection chassis. A rotating pressure plate is rotatably connected to the outer side of the rotating inner shaft. A miniature torsion spring is installed between the rotating inner shaft and the rotating pressure plate. The rotating pressure plate is located between the detection clamping groove and the clamping groove. A trapezoidal push bar is fixedly connected to one side of the rotating pressure plate. A fixing tooth is fixedly connected to the side of the rotating pressure plate away from the trapezoidal push bar. In use: Place the object to be detected on the top of the bottom cylinder and push the limiting slide plate to move in all directions. The compression spring causes the positioning clamp to fix the bottom of the object, causing the detection chassis to move downwards. When the detection chassis moves downwards, the inner fixing plate restricts the horizontal height of the inner positioning plate, causing the detection mounting plate to rotate upwards. This causes the detection end of the detection device to move closer to the object and compress it, allowing the processing box to collect data. At the same time, the inner positioning plate moves towards the object, causing the positioning pin to move inside the displacement processing structure for calculation. Simultaneously, when the detection mounting plate rotates upwards, it pushes the trapezoidal push bar, causing one side of the fixed insert to move towards the limiting slide plate, thus fixing the fixed insert to the limiting slide plate and preventing the object from shifting.

[0006] Preferably, a movable threaded column is fixedly connected to the bottom of the bottom cylinder; a threaded inner plate is threadedly connected to the outer side of the movable threaded column; a connecting inner cylinder is fixedly connected to the outer side of the threaded inner plate; a connecting bottom cylinder is fixedly connected to the bottom of the connecting inner cylinder; an inner limiting ring is fixedly connected to the outer side of the movable threaded column; an outer limiting ring is rotatably connected to the outer side of the inner limiting ring; movable limiting cylinders are fixedly connected at equal intervals to the outer side of the outer limiting ring; an mounting inner plate is fixedly connected to the bottom of the mounting outer cylinder; a limiting shaft is fixedly connected to the bottom of the mounting inner plate; and the movable limiting cylinder is slidably engaged with the outer side of the limiting shaft. A return spring is installed between the outer limiting ring and the threaded inner plate. A monitoring screen is fixedly connected to the outer side of the mounting outer cylinder. A protective cover is installed on the top of the mounting outer cylinder, and a protective bottom cylinder is fixedly connected to the bottom of the mounting outer cylinder. In use: by setting the threaded inner plate, the connecting bottom cylinder can be pulled for brief compression, and the return spring will rebound. Alternatively, the connecting bottom cylinder can be selected to drive the threaded inner plate to rotate, causing the movable threaded column to move up and down, fixing the position of the movable threaded column for long-term compression testing. The monitoring screen can quickly understand the real-time test data. The protective cover and protective bottom cylinder facilitate storage and protection of the device.

[0007] This invention provides an improved mechanical strength testing device for insulator materials, which has the following improvements and advantages compared with the prior art: Firstly, the mechanical strength testing equipment for insulator materials described in this invention places the object to be tested on the top of the bottom cylinder, pushes the limiting slide plate to move in all directions, squeezes the compression spring, and fixes the bottom of the object with the positioning clamp, so that the entire testing chassis is downward. When the testing chassis moves downward, because the inner fixing plate restricts the horizontal height of the inner positioning plate, the testing mounting plate will rotate upward, so that the testing end of the testing device moves closer to the object and squeezes it, so that the processing box collects data. At the same time, the inner positioning plate will move towards the object, so that the positioning pin moves inside the displacement processing structure for calculation. At the same time, when the testing mounting plate rotates upward, it will push the trapezoidal push bar, so that one side of the fixed insert tooth moves towards the limiting slide plate, so that the fixed insert tooth fixes the limiting slide plate and prevents the object from shifting. Secondly, the mechanical strength testing equipment for insulator materials described in this invention can be used to briefly compress the connecting bottom cylinder by setting a threaded inner plate, and the bottom cylinder can be used to rotate the threaded inner plate by returning the spring. Alternatively, the moving threaded column can be moved up and down by the connecting bottom cylinder to fix the position of the moving threaded column and perform long-term compression testing. The monitoring screen can quickly understand the real-time test data. The protective cover and protective bottom cylinder facilitate the storage and protection of the device. In summary, the mechanical strength testing equipment for insulator materials described in this invention has a compact and lightweight structure, allowing for spot checks during laboratory or factory production and research. It is also easy to carry to complex outdoor work sites, enabling simultaneous multi-directional pressure testing. While clamping and fixing the insulator, it automatically feeds the testing probe. The operation process is simple, requiring no additional auxiliary tools, and the testing efficiency is high. It meets the needs of rapid on-site mechanical strength testing of insulators and overcomes the shortcomings of existing devices. Attached Figure Description

[0010] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0011] This invention provides an improved device for testing the mechanical strength of insulator materials. The technical solution of this invention is as follows: like Figures 1-7 As shown, an insulator material mechanical strength testing device includes an outer mounting cylinder 1 and a testing base 6. A bottom cylinder 8 is fixedly connected to the inner side of the testing base 6, and four movable clamping blocks 9 are fixedly connected to the outer side of the bottom cylinder 8. Four testing clamping slots are formed on the inner side of the testing base 6. Four inner fixing plates 14 are fixedly connected to the inner side of the outer mounting cylinder 1. An inner positioning plate 13 is slidably engaged with the inner side of the inner fixing plate 14. A fixing clamping block 12 is fixedly connected to one end of the inner positioning plate 13. A testing mounting plate 7 is rotatably connected between the fixing clamping block 12 and the movable clamping block 9. A testing device 10 is installed inside the testing mounting plate 7. The testing device 10 performs testing. The detection device 10 is fixedly connected to the bottom of the detection mounting plate 7 and the processing box 11. The top of the inner fixing plate 14 has a detection groove. The top of the inner positioning plate 13 has a positioning pin 15. The top of the inner fixing plate 14 has a displacement processing structure 16. The positioning pin 15 is slidably engaged in the detection groove and the displacement processing structure 16. The inner side of the detection chassis 6 has four clamping slots. Two limiting slide shafts 17 are fixedly connected in the clamping slots. The outer side of the limiting slide shafts 17 is slidably engaged with a limiting slide plate 18. A compression spring 20 is movably sleeved on the outer side of the limiting slide shafts 17. A positioning clamping block 19 is fixedly connected to one side of the positioning slide plate 18. A rotating inner shaft 21 is fixedly connected to the inner side of the detection chassis 6. A rotating pressure plate 22 is rotatably connected to the outer side of the rotating inner shaft 21. A miniature torsion spring is installed between the rotating inner shaft 21 and the rotating pressure plate 22. The rotating pressure plate 22 is located between the detection clamping groove and the clamping groove. A trapezoidal pusher 23 is fixedly connected to one side of the rotating pressure plate 22. A fixing tooth 24 is fixedly connected to the side of the rotating pressure plate 22 away from the trapezoidal pusher 23. In use: Place the object to be detected on the top of the bottom cylinder 8, push the limiting slide plate 18 to move in all directions, squeeze the compression spring 20, and make the positioning clamping block 19... 9. Fix the bottom of the object so that the detection chassis 6 is facing downwards. When the detection chassis 6 moves downwards, the inner fixing plate 14 restricts the horizontal height of the inner positioning plate 13, causing the detection mounting plate 7 to rotate upwards. This causes the detection end of the detection device 10 to move closer to the object and press against it, allowing the processing box 11 to collect data. At the same time, the inner positioning plate 13 moves towards the object, causing the positioning pin 15 to move inside the displacement processing structure 16 for calculation. Simultaneously, when the detection mounting plate 7 rotates upwards, it pushes the trapezoidal push bar 23, causing one side of the fixing tooth 24 to move towards the limiting slide plate 18, thus fixing the fixing tooth 24 to the limiting slide plate 18 and preventing the object from shifting.

[0012] Furthermore, a movable threaded column 25 is fixedly connected to the bottom of the bottom cylinder 8. A threaded inner plate 30 is threadedly connected to the outer side of the movable threaded column 25. A connecting inner cylinder 31 is fixedly connected to the outer side of the threaded inner plate 30. A connecting bottom cylinder 32 is fixedly connected to the bottom of the connecting inner cylinder 31. An inner limiting ring 26 is fixedly connected to the outer side of the movable threaded column 25. An outer limiting ring 27 is rotatably connected to the outer side of the inner limiting ring 26. Movable limiting cylinders 28 are fixedly connected at equal intervals to the outer side of the outer limiting ring 27. An mounting inner plate 4 is fixedly connected to the bottom of the mounting outer cylinder 1. A limiting shaft 29 is fixedly connected to the bottom of the mounting inner plate 4. The movable limiting cylinder 28 is slidably engaged with the outer side of the limiting shaft 29. A return spring 33 is installed between the ring 27 and the threaded inner plate 30. A monitoring screen 5 is fixedly connected to the outside of the mounting outer cylinder 1. A protective cover 2 is installed on the top of the mounting outer cylinder 1. A protective bottom cylinder 3 is fixedly connected to the bottom of the mounting outer cylinder 1. In use: by setting the threaded inner plate 30, the connecting bottom cylinder 32 can be pulled to perform a short-term compression. The return spring 33 will rebound. Alternatively, the connecting bottom cylinder 32 can be selected to drive the threaded inner plate 30 to rotate, which will drive the movable threaded column 25 to move up and down, so that the position of the movable threaded column 25 is fixed for long-term compression testing. The monitoring screen 5 can quickly understand the real-time test data. The protective cover 2 and the protective bottom cylinder 3 facilitate the storage and protection of the device.

[0013] Working principle: In use: Place the object to be detected on top of the bottom cylinder 8, push the limiting slide plate 18 to move in all directions, compress the compression spring 20, and fix the bottom of the object with the positioning clamp 19, so that the detection base 6 is downward. When the detection base 6 moves downward, because the inner fixing plate 14 restricts the horizontal height of the inner positioning plate 13, the detection mounting plate 7 will rotate upward, so that the detection end of the detection device 10 moves closer to the object and squeezes it, so that the processing box 11 collects data. At the same time, the inner positioning plate 13 will move towards the object, so that the positioning pin 15 moves inside the displacement processing structure 16 to perform calculations. At the same time, the detection mounting plate 7 moves towards the object. When rotating upwards, it pushes the trapezoidal push bar 23, causing one side of the fixed insert tooth 24 to move towards the limiting slide plate 18, thus fixing the fixed insert tooth 24 to the limiting slide plate 18 and preventing the object from shifting. By setting the threaded inner plate 30, the connecting bottom cylinder 32 can be pulled for short-term compression, and the return spring 33 will rebound. Alternatively, the connecting bottom cylinder 32 can be selected to drive the threaded inner plate 30 to rotate, causing the movable threaded column 25 to move up and down, thus fixing the position of the movable threaded column 25 for long-term compression testing. The monitoring screen 5 can be set up to quickly understand the real-time test data. The protective cover 2 and the protective bottom cylinder 3 facilitate the storage and protection of the device.
