Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment insulation testing, and specifically to a device for inspecting the performance of electrical equipment components. Background Art

[0002] As a device for electrical equipment or conductive electrical insulation and mechanical fixation that bears potential difference, insulators play a crucial role in the safe and reliable operation of transmission lines. During the process of their production and manufacturing, testing and inspection of their insulation performance are one of the important measures to ensure their safe use.

[0003] The Chinese utility model patent with the authorization announcement number CN210863935U discloses a suspension porcelain insulator insulation performance detection device. This patent transports the insulator to the lower part of the clamping mechanism through a conveying mechanism, clamps the insulator with the clamping mechanism, and then outputs a high voltage to the insulator by a power supply box to detect the insulation performance of the insulator. During the testing process, the conveying mechanism needs to stop and wait. After the insulator completes the test and returns to the conveying mechanism again, the conveying operation will continue. In this way, continuous cycling and continuous testing of the insulator are carried out. Not only is the testing efficiency relatively low, but also the mechanical loss generated during the testing process is relatively large, which is not conducive to the continuous and stable progress of the testing operation. In addition, there are also some assembly lines that adopt a non-stop testing method, picking and placing the insulator during the conveying process. Its testing efficiency is relatively high, but during the picking and placing process, the insulator will be affected by the inertia generated when changing from the state of moving synchronously with the conveying device to the static state, and the friction force generated when changing from the static state to the state of moving synchronously with the conveying device. The above situations all pose risks to the quality of the insulator. Especially for glass insulators, due to their high brittleness, they are more likely to be damaged when the state changes. Summary of the Invention

[0004] The present invention provides a device for inspecting the performance of electrical equipment components to solve the problem that the testing efficiency and testing risk are inversely proportional in related technologies.

[0005] The present invention provides a performance inspection device for electrical equipment components, including a double-row conveying mechanism; the double-row conveying mechanism is used to convey insulators so that the insulators pass through the test position; a synchronous testing mechanism, the synchronous testing mechanism includes a drive control component and a mounting seat with a horizontal mounting surface, the mounting seats are symmetrically distributed up and down, and the mounting seat located above includes a telescopic part and a fixed part, the drive control component controls the mounting seat to cycle through the test position, the path of the mounting seat when passing through the test position is arc-shaped and the horizontal mounting surface of the mounting seat is always in a horizontal state, and clamping members are arranged on the horizontal mounting surfaces; during the process that the insulators pass through the test position, the mounting seat first moves upward along an arc trajectory and then moves downward along an arc trajectory. During this process, the insulators are first limited and fixed, then they are separated from the double-row conveying mechanism, then they are powered on for testing, and finally they return to the double-row conveying mechanism again. During the whole process, the insulators always maintain the conveying motion state in the conveying direction.

[0006] In a possible implementation manner, the drive control component includes a rotating disk and a gear ring. A connecting seat with a gear is rotatably connected to the rotating disk. The gear is meshed with the inner part of the gear ring. The mounting seat is installed on the connecting seat. During the rotation of the rotating disk, the gear meshes with the gear ring and drives the mounting seat to rotate through the connecting seat. The rotation direction of the mounting seat is opposite to that of the rotating disk, so that the horizontal mounting surface on the mounting seat is always in a horizontal state.

[0007] In a possible implementation manner, the synchronous testing mechanism further includes a pre-calibration component. The pre-calibration component includes a reciprocating sliding seat. A test piece is slidably arranged on the reciprocating sliding seat. A jacking piece is slidably connected up and down on the test piece. During the process of calibrating the position of the insulator, when the insulator is not in the preset position, the test piece will first change its own position according to the position of the insulator, and then reset to calibrate the position of the insulator.

[0008] In a possible implementation manner, the test piece includes a U-shaped test plate and a cylindrical limiting column. The test plate includes a horizontal section and a vertical section. The vertical sections are symmetrically arranged on the horizontal section, and the opposite surfaces and the back surfaces of the vertical sections are both trapezoidal. The limiting columns are symmetrically arranged and used to limit the test plate.

[0009] In a possible implementation manner, the jacking piece includes a limiting block and a sliding column with a bearing plate connected to the top. A ball is rotatably embedded at the bottom of the sliding column. The limiting block is trapezoidal.

[0010] In a possible implementation manner, a contact block is elastically and slidably inserted on the horizontal mounting surface. The upper surface of the contact block is a friction surface. The contact block is used to initially restrain the end of the insulator.

[0011] In a possible implementation manner, the clamping member includes an energized portion and an insulating clamping portion. When the clamping portion clamps and fixes the end of the insulator, the energized portion simultaneously energizes the insulator.

[0012] One or more of the above technical solutions in the embodiments of the present invention have at least one of the following technical effects: 1. According to an electrical equipment component performance inspection device provided by an embodiment of the present invention, through the cooperation of a double-row conveying mechanism and a synchronous testing mechanism, during the conveying process, the insulator is energized and tested. The entire testing process does not require stopping the machine, effectively improving the testing efficiency, and the synchronous testing mechanism hardly or completely does not generate frictional force of relative movement with the insulator, effectively avoiding the risk that the insulator is affected by additional force during the testing process and its quality is affected.

[0013] 2. According to an electrical equipment component performance inspection device provided by an embodiment of the present invention, during the testing process, the control mounting seat moves through the testing position in a manner of first moving upward along an arc trajectory and then moving downward along an arc trajectory. Combining the clamping member to pick up, place, and energize and test the insulator during the conveying process, the insulator always maintains a moving state and completes the test in this state, effectively avoiding the risk that the insulator is affected by additional force during the testing process and its quality is affected.

[0014] 3. According to an electrical equipment component performance inspection device provided by an embodiment of the present invention, the position of the insulator is pre-corrected by a pre-correction component, so that the insulator enters the testing position in an accurate position state, facilitating the smooth progress of subsequent testing work, improving the stability of the testing process, and during the entire correction process, the pre-correction component hardly or completely does not generate relative movement friction with the insulator, effectively ensuring the integrity of the insulator.

[0015] 4. According to an electrical equipment component performance inspection device provided by an embodiment of the present invention, first, the end of the insulator is preliminarily restrained by the friction surface on the contact block to prevent the end from slipping and shifting, and then the end is clamped and fixed by the clamping member, which can effectively improve the stability of clamping and fixing the insulator, so that the insulator maintains a stable vertical state during the testing process, facilitating subsequent stable return to the double-row conveying mechanism.

[0025] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementation manners disclosed below.

[0026] Please refer to Figure 1 、 Figure 2 and Figure 3 , a performance inspection device for an electrical equipment component, including a double-column conveying mechanism 1 and a synchronous testing mechanism 2. The double-column conveying mechanism 1 conveys insulators from right to left so that the insulators pass through the test position, as Figure 1As shown, during the conveying process, the insulator remains in a vertical state and both of its ends are in an exposed state. The synchronous testing mechanism 2 includes a drive control component 21 and a mounting base 22 with a horizontal mounting surface. The mounting bases 22 are distributed vertically and are respectively located above and below the double-row conveying mechanism 1. The upper mounting base 22 includes an elastic telescopic part and a fixed connection part. The drive control component 21 controls the vertically distributed synchronous mounting bases 22 to cycle through the testing position. The path of the mounting base 22 when passing through the testing position is arc-shaped and the horizontal mounting surface of the mounting base 22 always remains in a horizontal state. Clamping members 23 are provided on the horizontal mounting surfaces.

[0027] During the process of the insulator passing through the testing position, the lower mounting base 22 first moves upward along an arc trajectory and then moves downward along an arc trajectory. The upper mounting base 22 first moves downward along an arc trajectory and then moves upward along an arc trajectory. During this process, the clamping member 23 on the upper mounting base 22 first limits and fixes the upper end portion of the insulator, and the clamping member 23 on the lower mounting base 22 limits and fixes the lower end portion of the insulator. Then, the insulator is separated from the double-row conveying mechanism 1 and is electrically tested. After that, the insulator is returned to the double-row conveying mechanism 1 again and the limit fixation of the insulator is released. During this process, the elastic telescopic part of the upper mounting base 22 undergoes corresponding telescopic deformation along with the displacement change of the insulator in the vertical direction, enabling the insulator to move stably. After that, the double-row conveying mechanism 1 continues to convey the insulator. Throughout the above process, the insulator remains in the conveying state, without the need for the double-row conveying mechanism 1 to stop and wait, effectively improving the testing efficiency. And during the testing process, the synchronous testing mechanism 2 hardly or completely does not generate frictional force of relative movement with the insulator, effectively avoiding the risk that the insulator is affected in quality due to additional force during the testing process. Among them, the clamping member 23 includes an energizing part and an insulating clamping part. When the clamping part clamps and fixes the end portion of the insulator, the energizing part synchronously energizes the insulator.

[0028] Refer to Figure 2 、 Figure 3 and Figure 7 As shown in Figure 3As shown, the symmetrically arranged upper and lower rotating disks 211 rotate in opposite directions synchronously, so that the mounting seats 22 thereon pass through the test position synchronously. During the rotation of the rotating disks 211, the gears mesh with the toothed rings 212 to make the connecting seats 213 rotate self - synchronously, and the rotation speed of the connecting seats 213 is equal to the rotation speed of the rotating disks 211. The connecting seats 213 drive the mounting seats 22 to rotate, so that the horizontal mounting surfaces on the mounting seats 22 are in a horizontal state, and then the clamping members 23 thereon can smoothly clamp and fix the ends of the insulators. And within a certain range, even if the levelness of the horizontal mounting surface of the mounting seat 22 changes due to loss or cumulative error, it does not affect the clamping of the ends of the insulators by the clamping members 23. Among them, the drive control assembly 21 further includes a synchronous drive member, such as Figure 7 As shown, the synchronous drive member includes two synchronous pulleys and a synchronous belt. The synchronous pulleys are arranged symmetrically up and down. The synchronous belt is sleeved on the synchronous pulleys to make them rotate synchronously. Synchronous gears I are connected to both synchronous pulleys, and synchronous gears II are connected to the rotating disks 211. The synchronous gears I and the synchronous gears II correspond one by one, and the synchronous gears I are located between the symmetrically arranged synchronous gears II, as Figure 7 As shown, the synchronous gear II on the upper rotating disk 211 directly meshes with the synchronous gear I on the upper synchronous pulley, while the synchronous gear II on the lower rotating disk 211 indirectly meshes with the synchronous gear I on the lower synchronous pulley through an intermediate gear. During the rotation of the synchronous pulleys, the symmetrically arranged rotating disks 211 are controlled to rotate synchronously and in opposite directions through the direct and indirect meshing of the synchronous gears I and the synchronous gears II.

[0029] Refer to Figure 3 and Figure 8 , a contact block 3 is elastically and slidably inserted on the horizontal mounting surface. Among them, the elastic telescopic part in the upper mounting seat 22 is slidably connected to the contact block 3. The contact surface of the contact block 3 is a friction surface, and the friction surface is an insulating surface. The contact block 3 contacts the end of the insulator and is used for initially limiting the end of the insulator. Before the clamping member 23 clamps and fixes the end of the insulator, the end of the insulator will first contact the friction surface of the contact block 3 and make the contact block 3 slide into the mounting seat 22. Using the contact between the friction surface and the end face of the insulator can prevent the end of the insulator from slipping and affecting the vertical state of the insulator. Then, the clamping member 23 is used to clamp and fix its end, which can effectively improve the stability of clamping and fixing the insulator, so that the insulator maintains a stable vertical state during the test and is convenient to return to the double - row conveying mechanism 1 stably later.

[0030] Refer to Figure 3 、 Figure 4 and Figure 5, the synchronous testing mechanism 2 further includes a pre-calibration component 24. The pre-calibration component 24 includes a reciprocating sliding seat 241 which is slidably connected to the base in the left-right direction. A test piece 242 is slidably arranged on the reciprocating sliding seat 241 in the front-back direction. A jacking piece 243 is slidably connected to the test piece 242 in the up-down direction. As Figure 3 shown, before the insulator enters the test position, it first passes through the calibration area. When the insulator enters the calibration area, if the insulator is not in the preset position, it will change the position of the test piece 242 according to its own position. The jacking piece 243 moves with the test piece 242. Then, the reciprocating sliding seat 241 will slide to the left to move synchronously with the insulator. During the sliding process, the jacking piece 243 will jack up the insulator upward to make it leave the double-row conveying mechanism 1. Then, the test piece 242 will drive the insulator to reset, completing the calibration work of the insulator's position, enabling the insulator to enter the test position in an accurate position state, facilitating the smooth progress of subsequent testing work, improving the stability of the testing process, and during the entire calibration process, the pre-calibration component 24 hardly or completely does not generate frictional relative movement with the insulator, effectively ensuring the integrity of the insulator.

[0031] Refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , the test piece 242 includes a U-shaped test plate 2421 and a cylindrical limiting column 2422. The test plate 2421 includes a horizontal section and a vertical section. The vertical sections are symmetrically arranged on the horizontal section in the front-back direction, and the top-view structures of the opposite and the back faces of the vertical sections are both trapezoidal. The limiting columns 2422 are symmetrically arranged and are used to limit the test plate 2421. When the insulator is not in the preset position, it will change the position of the test plate 2421. As Figure 6 shown, when the position of the insulator is biased backward, during the process of its moving between the test plates 2421, it will drive the test plate 2421 to slide backward. Then, as the reciprocating sliding seat 241 slides to the left, the jacking piece 243 first jacks up the insulator upward. Then, the test plate 2421 will pass through the limiting columns 2422. As Figure 6 shown, under the limitation of the limiting columns 2422, the test plate 2421 resets, thereby calibrating the position of the insulator so that the insulator is accurately in the preset position. Then, the jacking piece 243 resets, and the insulator returns to the double-row conveying mechanism 1 to continue conveying, and the reciprocating sliding seat 241 resets to the right. Among them, the sliding movement of the reciprocating sliding seat 241 can be controlled by a cylinder, and the test piece 242 moves synchronously with the reciprocating sliding seat 241.

[0032] Refer to Figure 2 and Figure 4, the lifting member 243 includes a limiting block 2431 and a sliding column 2433 with a bearing plate 2432 fixedly connected to the top. The sliding column 2433 is slidably mounted on the reciprocating sliding seat 241 up and down. The limiting block 2431 is trapezoidal and fixedly mounted on the base. A ball is rotatably fitted at the bottom of the sliding column 2433. During the process of the reciprocating sliding seat 241 sliding leftward, the ball on the sliding column 2433 will roll along the surface of the limiting block 2431. As Figure 4 shown, the limiting of the ball by the limiting block 2431 causes the sliding column 2433 to slide upward, and the insulator is lifted upward by using the bearing plate 2432.

[0033] In the embodiments of the present invention, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "under" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0034] In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "arranged", "connected", "installed" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, an integral connection or a sliding connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components.
