Description

Technical Field

[0001] This invention relates to the technical field of insulator parameter measuring equipment, and specifically to a device for measuring the comprehensive parameters of an insulator. Background Technology

[0002] Insulator products involve multiple technical indicators, including dimensions, mechanical properties, material properties, and electrical properties. These parameters are key concerns for both manufacturers and users during the manufacturing and use of insulators.

[0003] Typically, to ensure the reliable performance of the insulator product, a large number of insulator products must be sampled and tested before leaving the factory and during user acceptance. The test parameters involved will cover all the parameters described above that describe the performance of the insulator product. Testing the insulator before leaving the factory can comprehensively measure the performance parameters of the insulator and avoid a large number of safety hazards during the use of the insulator.

[0004] The insulator's clamping height on the measuring device and the locking pins on the measuring device are essential for stable clamping of the insulator. Measuring parameters such as insulator disc diameter deviation, axial deviation, radial deviation, and galvanized layer thickness are routine tests for dimensional and mechanical properties and material performance parameters. Currently, in actual production, traditional methods are generally used, employing various instruments such as calipers, dial indicators, force measuring mechanisms, and coating testers, performed manually on different measuring fixtures or by different inspectors. These methods suffer from large measurement errors, high dependence on personnel skill levels, high labor intensity, long testing times, and low automation. In particular, testing multiple insulator parameters often requires repeatedly moving and clamping the insulator sample on different fixtures of the measuring device, resulting in significant physical exertion for the inspectors. Therefore, there is an urgent need for an automated device that can achieve one-time sample clamping and perform tests on as many parameters as possible. With the advancement of technology, some comprehensive testing devices with automatic measurement capabilities have emerged. However, the parameter testing items that the automated measurement methods and devices described in the literature can carry out are limited to the measurement of the form and position parameters of the insulator on the measuring device, such as the clamping height and disc diameter, or only the measurement of the pin locking force of the measuring device. Ultimately, they still cannot achieve the one-time clamping of the insulator test specimen on the measuring device and the completion of multiple parameter detection or measurement. Summary of the Invention

[0005] The technical problem to be solved by this invention is that when multiple parameters of an insulator need to be measured, the insulator needs to be clamped on different fixtures of the measuring device. The purpose of this invention is to provide a comprehensive parameter measuring device for insulators, which realizes the one-time clamping of the insulator sample on the measuring device and the completion of detection or measurement of multiple parameters.

[0006] This invention is achieved through the following technical solution:

[0007] A measuring device for comprehensive parameters of an insulator, comprising:

[0008] The first tensioning mechanism is mounted on the single cantilever structure and can extend and retract in the vertical direction.

[0009] The second tensioning mechanism is rotatable, and an insulator sample can be clamped between the second tensioning mechanism and the first tensioning mechanism.

[0010] When the first tensioning mechanism is in the extended state, the insulator test specimen is clamped between the second tensioning mechanism and the first tensioning mechanism through the first tensioning mechanism and the second tensioning mechanism.

[0011] When the first tensioning mechanism is in the retracted state, the insulator test specimen is tensioned between the first tensioning mechanism and the second tensioning mechanism.

[0012] Optionally, the single cantilever structure has a top plate, the first tensioning mechanism is fixed on the top plate, the upper end of the second tensioning mechanism passes through the upper end of the housing, the lower end of the second tensioning mechanism is disposed in the housing, the second tensioning mechanism itself can rotate, and the lower end of the second tensioning mechanism is connected to the rotary drive mechanism.

[0013] The first tensioning mechanism includes a first worm gear, a first worm, and a thrust connecting bearing. The first worm gear and the first worm mesh with each other. The thrust connecting bearing is connected to the first worm gear via a telescopic screw. One end of the thrust connecting bearing is connected to a replaceable standard connecting cup, which is connected to the insulator test specimen. The other end of the thrust connecting bearing is connected to the telescopic screw, enabling the insulator test specimen and the telescopic screw to rotate coaxially. This ensures that the telescopic screw is in a retracted state and the insulator test specimen can rotate horizontally in the tensioned state. When the telescopic screw of the first tensioning mechanism rises, the telescopic screw, the thrust connecting bearing, and the standard connecting cup move upward, achieving a tensioned connection of the insulator test specimen.

[0014] The second tensioning mechanism is connected to the insulator test specimen to achieve a tensioned connection. The lower end of the insulator cup head hardware is connected to the rotary drive mechanism so that after the insulator test specimen is tensioned, it can rotate in the horizontal direction. Here, the standard hardware of the insulator test specimen is connected to a ball-and-socket universal joint via a ball-and-socket connection. The lower end of the ball-and-socket universal joint is connected to the rotary drive mechanism so that after the insulator test specimen is tensioned, it can rotate in the horizontal direction.

[0015] Optionally, the first handwheel and the first motor are respectively connected to the two ends of the first worm of the first tensioning mechanism, and the end of the first motor away from the first worm is connected to a first digital measuring encoder for measuring the number of rotations of the first worm.

[0016] The telescopic screw is threadedly fitted inside the first worm gear. The telescopic screw can move axially due to the meshing of the first worm gear and the first worm and the rotation of the telescopic screw itself. The lower end of the telescopic screw is fixedly connected to the upper end of the thrust connection bearing. The lower end of the thrust connection bearing can be fixedly connected to the standard connection cup head through a threaded structure, so that the tensioned insulator test specimen can rotate in the horizontal direction.

[0017] The second tensioning mechanism includes the rotary drive mechanism and the ball cage universal joint;

[0018] Optionally, the standard connecting cup is threaded to the lower end of the thrust connecting bearing. When the first tensioning mechanism is in a retracted state or moves upward, the standard connecting cup can tension the insulator test specimen. The ball cage universal joint can swing the standard connecting cup off its axis within a certain range. The non-coaxial rotation of the ball cage universal joint and the telescopic screw or the standard connecting cup facilitates the clamping and rotation drive of the insulator test specimen. The lower end of the ball cage universal joint is fixedly connected to the rotation drive mechanism. The insulator test specimen can rotate horizontally. The lower end of the rotation drive mechanism is equipped with a second digital measuring encoder. The rotation drive mechanism and the drive device can be connected by a pulley, gear, or worm gear transmission method.

[0019] Optionally, multiple guide columns and a first lead screw are provided between the top plate and the box body. The guide columns are sleeved on a vertically movable lead screw slide mechanism. The lead screw slide mechanism is connected to the lifting and adjusting mechanism through the first lead screw. The rotation of the first lead screw causes the lead screw slide mechanism, i.e. the bottom plate, to move in the vertical direction.

[0020] Optionally, the lead screw slide mechanism includes a slide and a second lead screw. The bottom of the slide and the second lead screw are connected by a lead screw and a lead rod. The two ends of the second lead screw are respectively connected to a second handwheel and a slide telescopic drive motor. The end of the slide telescopic drive motor away from the second lead screw is connected to a third digital encoder for measuring the number of rotations of the second lead screw. The first lead screw passes through the base plate and is connected to the base plate by a lead screw nut. The rotation of the first lead screw causes the entire lead screw slide mechanism to move in the vertical direction.

[0021] Optionally, a quick-change sleeve-type test head connection structure is fixedly connected to the top of the slide table. This sleeve-type test head connection structure can move axially with the slide table. A force sensor is provided on the second lead screw. The force sensor is close to the slide table. The sleeve-type test head connection structure is connected to the force sensor by a thread at the end away from the slide table. The sleeve-type test head connection structure is engaged with a replaceable sleeve-type pull hook or push head probe and coating probe component by a pin for quick change of probe type and fixing of probe for horizontal measurement of push-pull force measurement and expansion coating measurement of insulator specimens.

[0022] Optionally, the lifting adjustment mechanism includes a second worm gear, a second worm, a first lead screw, and a nut. The nut is fixed on the lead screw slide mechanism and is threadedly connected to the first lead screw. The second worm gear and the second worm mesh with each other. Through the meshing of the second worm gear and the second worm and the rotation of the first lead screw itself, the lead screw slide mechanism can move vertically. The two ends of the second worm are respectively driven to a third handwheel and a second motor. The end of the second motor away from the second worm is electrically connected to a fourth digital encoder for measuring the number of rotations of the second worm, and for measuring the rotation angle of the first lead screw and calculating its lifting displacement.

[0023] Optionally, the bottom of the lead screw slide mechanism is provided with a precision four-axis optical adjustment slide and a first laser rangefinder. The housing is provided with a movable magnetic first linkage mechanism, on which a first light-receiving plate is provided. The first light-receiving plate is opposite to the first laser rangefinder. The top plate is provided with a precision two-axis adjustment slide, a second laser rangefinder, and a movable magnetic second linkage mechanism. The second linkage mechanism is provided with a second light-receiving plate, on which the second laser rangefinder is opposite to the second light-receiving plate.

[0024] The bottom of the lead screw slide mechanism is equipped with a precision-adjustable four-axis optical measurement slide, which can precisely adjust the measurement position and direction of the first laser rangefinder, and work with the first optical measurement auxiliary mechanism to align the measurement position of the first laser rangefinder with the light-receiving plate of the auxiliary measurement mechanism.

[0025] Specifically, the bottom of the top plate is provided with a precisely adjustable two-axis optical measurement slide, which can make small-range precise adjustments to the measurement position of the second laser rangefinder, and work with the second optical measurement auxiliary mechanism to align the measurement position of the second laser rangefinder with the light-receiving plate of the auxiliary measurement mechanism.

[0026] Optionally, the housing is equipped with a magnetically attached first optical measurement auxiliary mechanism, which is equipped with a first light-receiving plate. By appropriate adjustment, the first light-receiving plate is made to fit tightly against the surface of the insulator test specimen. The first light-receiving plate is aligned with the first laser rangefinder, and the first light-receiving plate can receive and reflect the measurement laser to the first laser rangefinder.

[0027] Specifically, the magnetic first optical measurement auxiliary mechanism can be placed in any convenient position such as the top plate or the bottom plate. The first optical measurement auxiliary mechanism and the first laser rangefinder can perform axial distance measurement of the insulator test specimen. The first optical measurement auxiliary mechanism is equipped with a first light-receiving plate. By appropriately adjusting the first light-receiving plate, it can be made to fit closely with the measured surface of the insulator test specimen and be aligned with the first laser rangefinder. The first light-receiving plate and the first laser rangefinder are relatively aligned. The light-receiving plate can receive and reflect the measurement laser to the first laser rangefinder.

[0028] The magnetic first linkage mechanism and its first light-receiving plate form the first optical measurement auxiliary mechanism, and the magnetic second linkage mechanism and its second light-receiving plate form the second optical measurement auxiliary mechanism. The magnetic first linkage mechanism and its first light-receiving plate are used to measure the radial deviation data and disc diameter data of the insulator test specimen, and the magnetic second linkage mechanism and its second light-receiving plate are used to measure the axial deviation data of the insulator test specimen. Through the two measurement auxiliary mechanisms, the disc diameter, axial deviation, and radial deviation of the insulator test specimen can be measured optically.

[0029] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0030] 1. The overall structure of this invention adopts a single cantilever open tensioning frame structure. The installation of the test specimen can be carried out in all directions except the back of the cantilever. The structure is simple and easy to operate.

[0031] 2. The first tensioning mechanism of the present invention is fixed on the cantilevered top plate, and the second tensioning mechanism is fixed on the bottom plate. The first tensioning mechanism is telescopic and the second tensioning mechanism is rotatable. The insulator test specimen is clamped between the second tensioning mechanism and the first tensioning mechanism through replaceable insulator standard connecting hardware. When the second tensioning mechanism is in the extended state, the insulator test specimen is replaced between the second tensioning mechanism and the first tensioning mechanism through a ball cage universal joint. When the second tensioning mechanism is in the retracted state, the tested insulator is tightened between the first tensioning mechanism and the second tensioning mechanism through the insulator cup head hardware on the first tensioning mechanism and the second tensioning mechanism, which facilitates various subsequent measurement operations and realizes that the insulator test specimen is clamped on the measuring device in one go.

[0032] 3. This invention is an insulator measuring device with a single cantilever open structure. The device is easy to operate and has the comprehensive testing capability to measure multiple parameters such as the structural height, disc diameter, radial deviation, axial deviation, pin locking force, and galvanized layer thickness of the insulator specimen. It can realize the rapid and automatic measurement of the above six parameters for suspension insulator specimens with a structural height and disc diameter not exceeding 500mm by clamping the insulator specimen once, and can ensure high measurement accuracy.

[0033] 4. In this invention, a first tensioning mechanism is combined with a second tensioning mechanism. During the test, the worm gear mechanism of the first tensioning mechanism is manually or electrically driven to raise and lower the standard connecting cup head, and the insulator cup head hardware of the second tensioning mechanism clamps the insulator test specimen in the vertical direction. That is, the tensioning and release of the test specimen can be achieved by electrically adjusting the lifting height of the ball cage universal joint and the telescopic rod. The structural height is measured by a digital encoding sensor coaxially mounted on the first motor of the first tensioning mechanism. That is, the height of the test specimen is measured by measuring the lifting displacement during the extension of the electric telescopic rod and the pushing of the insulator test specimen. At the same time, the second tensioning mechanism is connected to a rotary drive mechanism. Under the rotation of the rotary drive mechanism, the axial, radial, and disc diameter parameters of the tested insulator test specimen can be measured horizontally. At the lower end of the rotary drive mechanism, a digital encoding sensor is set to calculate the shaft rotation angle data of the rotary drive mechanism to achieve rotation angle control.

[0034] 5. This invention uses a first laser rangefinder in conjunction with a first optical measurement auxiliary mechanism to measure the distance of a suspended standard measuring component, obtaining the distance between the first laser rangefinder and the light-receiving plate of the auxiliary measurement mechanism. This distance is used as a reference distance for calibration. After the insulator test specimen is clamped, a first linkage mechanism in conjunction with the measurement auxiliary mechanism is used to place the first light-receiving plate in the optical path of the first laser rangefinder and in contact with the outer peripheral wall of the insulator test specimen. When the insulator test specimen rotates, the difference between the distance test data between the first light-receiving plate and the first laser rangefinder and the calibrated reference distance can be used to obtain the initial measurement data of the insulator's disc diameter. Combined with the insulator test specimen after the first light-receiving plate has scanned and rotated one revolution, the disc diameter measurement result can be calculated. At the same time, the radial deviation value of the tested insulator test specimen can be calculated by subtracting the minimum disc diameter measurement value from the maximum disc diameter measurement value between the first light-receiving plate and the first laser rangefinder.

[0035] 6. In this invention, a second laser rangefinder is arranged vertically in conjunction with a second optical measurement auxiliary mechanism. The measuring beam of the laser rangefinder is directed towards the second light-receiving plate of the vertical auxiliary measuring device or the second linkage mechanism. The axial deviation of the insulator is measured by measuring the distance between the second light-receiving plate of the second linkage mechanism and the second laser rangefinder. That is, the second light-receiving plate of the second linkage mechanism is attached to the outer end face of the insulator test specimen. The distance between the insulator and the second light-receiving plate of the second linkage mechanism is measured first. After the insulator rotates one revolution, the distance data between the second light-receiving plate of the second linkage mechanism and the second laser rangefinder is measured. The difference between the maximum distance and the minimum distance is the axial deviation of the insulator.

[0036] 7. The force sensor of the present invention is fixedly installed between the horizontal bar of the force measuring platform and the replaceable sleeve-type test head connection structure. The second lead screw cooperates with the bottom of the slide to realize the telescopic movement of the thrust test head or the coating test head. The slide moves left and right only when the second lead screw rotates. When the front section of the telescopic rod pushes and pulls the test head and starts to contact the locking pin of the insulator under test, the force sensor measures the applied thrust or pull force. The force condition of the locking pin can be recorded during the entire telescopic stroke of the telescopic slide, realizing the locking force measurement. At the same time, the encoder coaxially connected to the second lead screw realizes the telescopic length measurement for locking force measurement control.

[0037] 8. The slide table of the present invention can be fitted with a coating probe or a thrust probe through a replaceable sleeve-type test head connection structure. Only when the second lead screw rotates does the slide table move left and right, causing the coating probe to contact the outer peripheral wall of the insulator test specimen to realize coating measurement. At the same time, the force sensor measures the thrust of the sleeve-type test head connection structure on the coating probe to ensure that the applied force value for coating measurement is appropriate.

[0038] 9. The replaceable sleeve-type test head connection structure in this invention adopts a pin-fixed sleeve connection method. When measuring the locking force, a flat push head (push test head) or a hook pull head (pull hook) can be selected according to the R-type or W-type locking pin of the test object. When measuring the coating, a sleeve-type test head connection structure with spring buffer can be selected. That is, springs are installed on both sides of the sleeve of the sleeve-type test head connection structure. The springs are located between the push head and the plug head. The springs can buffer the coating measurement and realize the self-correction of the measurement angle. Attached Figure Description

Detailed Implementation

[0053] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0054] Example 1

[0055] like Figure 1-4 As shown, this embodiment provides a measuring device for comprehensive parameters of insulators, including: a housing 1 and a single cantilever structure, a first tensioning mechanism 6 and a second tensioning mechanism 12. The first tensioning mechanism 6 is disposed on the top plate 5 of the single cantilever structure, and the first tensioning mechanism 6 can extend and retract in the vertical direction. The second tensioning mechanism 12 can rotate itself, and an insulator sample 28 can be clamped between the second tensioning mechanism 12 and the first tensioning mechanism 6.

[0056] When the first tensioning mechanism 6 is in the extended state, the insulator test specimen 28 is clamped between the second tensioning mechanism 12 and the first tensioning mechanism 6 through the first tensioning mechanism 6 and the second tensioning mechanism 12.

[0057] When the first tensioning mechanism 6 is in the retracted state, the insulator test piece 28 is tensioned between the first tensioning mechanism 6 and the second tensioning mechanism 12 through the first tensioning mechanism 6 and the second tensioning mechanism 12.

[0058] like Figure 1 , 5 As shown, the first tensioning mechanism 6 is detachably fixed on the top plate 5, the upper end of the second tensioning mechanism 12 passes through the upper end of the housing 1, the lower end of the second tensioning mechanism 12 is located inside the housing 1, the second tensioning mechanism 12 itself can rotate, and the lower end of the second tensioning mechanism 12 is connected to the rotary drive mechanism 30.

[0059] The first tensioning mechanism 6 includes a first worm gear 23a, a first worm 24b, and a thrust connecting bearing 25. The first worm gear 23a and the first worm 24a mesh with each other. The thrust connecting bearing 25 is connected to the first worm gear 23a via a telescopic screw 61. One end of the thrust connecting bearing 25 is connected to a replaceable standard connecting cup head 26. The standard connecting cup head 26 is connected to the insulator test specimen 28, that is, the upper end of the standard connecting cup head 26 of the insulator test specimen 28 is inserted into the ball vortex 261 of the standard connecting cup head 26. The other end of the thrust connecting bearing 25 is connected to the telescopic screw 61, which enables the insulator test specimen 28 and the telescopic screw 61 to rotate coaxially, so as to ensure that the telescopic screw 61 is in the retracted state and the insulator test specimen 28 can rotate in the horizontal direction in the tensioned state.

[0060] The second tensioning mechanism 12 is connected to the lower end of the insulator test specimen 28 to achieve tensioning connection of the insulator test specimen 28. The lower end of the insulator test specimen 28 is connected to the rotary drive mechanism 30 to achieve tensioning. After the insulator test specimen 28 is tensioned, the insulator test specimen 28 can rotate in the horizontal direction.

[0061] The first handwheel 14a and the first motor 21a are respectively connected to the two ends of the first worm 24a of the first tensioning mechanism 6. The end of the first motor 21a away from the first worm 24a is connected to a first digital measuring encoder 20a for measuring the number of rotations of the first worm 24a.

[0062] The lower end of the telescopic rod 61 is fixedly connected to the upper end of the thrust connection bearing 25. The lower end of the thrust connection bearing 25 and the standard connection cup head 26 can be connected by threads to allow the tensioned insulator test specimen 28 to rotate in the horizontal direction.

[0063] The second tensioning mechanism 12 includes a rotary drive mechanism 30 and a ball cage universal joint 121.

[0064] When the first tensioning mechanism 6 is in the retracted state or moved upward, the standard connecting cup head 26 can tension the insulator test specimen 28, and the ball cage universal joint 121 can swing off its axis. The non-coaxial rotation of the ball cage universal joint 121 and the telescopic screw 61 facilitates the clamping and rotation drive of the insulator test specimen 28. The lower end of the ball cage universal joint 121 is fixedly connected to the rotation drive mechanism 30, and the insulator test specimen 28 can rotate horizontally. The lower end of the rotation drive mechanism 30 is equipped with a second digital measuring encoder 20b. The rotation drive mechanism 30 and the drive device 31 (which can be a motor) can be connected by a pulley, gear or worm gear transmission method.

[0065] Depend on Figure 5 It can be seen that the second tensioning mechanism 12, the thrust connecting bearing 25, and the ball cage universal joint 121 are on the same axis. The first handwheel 14a or the first motor 21a drives the first worm 24a to rotate forward, causing the first worm wheel 23a to rotate forward, and the thrust connecting bearing 25 to rotate forward. The drive device 31 drives the drive mechanism 30 of the second tensioning mechanism 12 to rotate forward, and the ball cage universal joint 121 to rotate forward. Similarly, the first handwheel 14a or the first motor 21a drives the first worm 24a to rotate in reverse, causing the first worm wheel 23a to rotate in reverse. The drive device 31 drives the drive mechanism 30 of the second tensioning mechanism 12 to rotate in reverse, and the ball cage universal joint 121 to rotate in reverse.

[0066] The extension of the telescopic screw 61 enables the insulator test specimen 28 to be clamped between the second tensioning mechanism 12 and the first tensioning mechanism 6, and the retraction of the telescopic screw 61 enables the insulator test specimen 28 to be tightened between the second tensioning mechanism 12 and the first tensioning mechanism 6.

[0067] like Figure 1 , 6 As shown, multiple guide columns 151 and a first lead screw 3 are provided between the top plate 5 and the box body 1. The guide columns 151 are sleeved on the vertically movable lead screw slide mechanism 2. The lead screw slide mechanism 2 is connected to the lifting and adjusting mechanism 4 through the first lead screw 3.

[0068] like Figure 6As shown, the lead screw slide mechanism 2 includes a slide 15 and a second lead screw 22. The bottom of the slide 15 and the second lead screw 22 are connected by a lead screw and screw drive mechanism. The two ends of the second lead screw 22 are respectively connected to a second handwheel 14b and a slide telescopic drive motor 21b. The end of the slide telescopic drive motor 21b away from the second lead screw 22 is connected to a third digital encoder 20c for measuring the number of rotations of the second lead screw 22. The first lead screw 3 passes through the base plate 152 and is connected to the base plate 152 by a lead screw nut. A sleeve-type test head connection structure 18 is fixedly connected to the top of the slide 15. The sleeve-type test head connection structure 18 can move axially with the slide 15. A force sensor 17 is provided on the sleeve-type test head connection structure 18. The force sensor 17 is close to the slide 15. The end of the sleeve-type test head connection structure 18 away from the slide 15 is fixed to a hook 33 or a push head 182 by a pin 32.

[0069] like Figure 7 As shown, the lifting adjustment mechanism 4 includes a second worm gear 23b, a second worm 24b, a first lead screw 3, and a nut 311. The nut 311 is fixed on the lead screw slide mechanism 2 and is threadedly connected to the first lead screw 3. The second worm gear 23b and the second worm 24b mesh with each other. Through the meshing of the second worm gear 23b and the second worm 24b, and the fact that the first lead screw 3 can rotate on its own, the lead screw slide mechanism 2 can move vertically. The two ends of the second worm 24b are respectively connected to a third handwheel 14c and a second motor 21c. The end of the second motor 21c away from the second worm 24b is connected to a fourth digital encoder 20d for measuring the number of rotations of the second worm 24b.

[0070] It should be noted that the bottom of the slide table 15 is connected to the second lead screw 22 by means of a lead screw and screw transmission. By rotating the second lead screw 22, the slide table 15 can move linearly in the left and right directions. The nut 311 is connected to the first lead screw 3 by a thread. The nut 311 is fixed on the lead screw slide table mechanism 2. By rotating the first lead screw 3, the entire lead screw slide table mechanism 2 can move up and down in the vertical direction.

[0071] like Figure 1-4 As shown, a sleeve-type testing device 9 is fixedly connected to the top of the slide table 15. The sleeve-type testing device 9 is an axially telescopic sleeve-type testing head connection structure 18. A force sensor 17 is provided on the sleeve-type testing head connection structure 18. The sleeve-type testing head connection structure 18 can move axially with the slide table 15. The force sensor 17 is close to the slide table 15. The end of the sleeve-type testing head connection structure 18 away from the slide table 15 is fixed to the pull hook 33, the push head 182, or the coated probe 34 by a pin 32.

[0073] The bottom of the lead screw slide mechanism 2 is equipped with a precision four-axis adjustable slide and a first laser rangefinder 10.

The first linkage mechanism 11 is equipped with a first light-receiving plate 13a, which is connected to the first laser rangefinder 10.

[0074] The housing 1 is equipped with a magnetically attached first optical measurement auxiliary mechanism, which is equipped with a first light-receiving plate 13a. By appropriate adjustment, the first light-receiving plate 13a is brought into contact with the measured surface of the insulator test specimen 28. The first light-receiving plate 13a is aligned with the first laser rangefinder 10. The first light-receiving plate 13a and the first laser rangefinder 10 are relatively aligned. The first light-receiving plate 13a can receive and reflect the measurement laser to the first laser rangefinder 10.

[0075] Specifically, the magnetic first optical measurement auxiliary mechanism can be placed in any convenient position such as the top plate or the bottom plate. The cooperation between the first optical measurement auxiliary mechanism and the first laser rangefinder 10 can perform axial distance measurement of the insulator test specimen 28. The first optical measurement auxiliary mechanism is provided with a first light-receiving plate 13a. By appropriately adjusting the first light-receiving plate 13a to be closely attached to and aligned with the measured edge of the insulator test specimen 28 and the first laser rangefinder 10, the first light-receiving plate 13a and the first laser rangefinder 10 are aligned. The first light-receiving plate 13a can receive and reflect the measurement laser to the first laser rangefinder 10.

[0076] The bottom of the lead screw slide mechanism 2 is equipped with a precision four-axis optical adjustment slide, on which the first laser rangefinder 10 is fixed. The combination of the first optical measurement auxiliary mechanism and the first laser rangefinder 10 enables the first optical measurement auxiliary mechanism to make precise adjustments to the measurement position and direction relative to the first laser rangefinder 10.

The form and position parameters of the insulator test specimen can be measured optically through the two measurement auxiliary mechanisms.

[0079] Example 2

[0080] Based on Example 1, such as Figure 11 As shown, the sleeve-type test head connection structure 18 includes a rod-shaped part and a cylindrical part. The rod-shaped part includes a first rod body 181 and a plug 186, which are connected. The cylindrical part includes a pusher 182 and a second rod body 183. A blind hole 184 is opened in the pusher 182, and a threaded hole 185 is opened on the side wall of the pusher 182. The blind hole 184 communicates with the threaded hole 185, and the plug 186 is inserted into the blind hole 184.

[0081] like Figure 9 A hook 33 is fixedly connected to the end of the second rod 183 away from the push head 182 by a thrust screw 32 or a pin 32, or the end of the second rod 183 away from the push head 182 is connected to the thrust test head 19 or the coating test head 34, the coating test head 34 being a rod-shaped test head.

[0082] A horizontal bar 16 is fixedly connected to the top of the slide table 15, and a force sensor 17 is fixedly installed between the horizontal bar 16 and the first rod 181.

[0083] from Figure 9 , 11It is known that the hook 33 is locked to the end of the second rod 183 away from the push head 182 by the thrust screw 32. The hook 33 can be hooked on the rotating shaft of the insulator test specimen 28 for measuring the tension of the locking pin. After the position of the plug 186 in the blind hole 184 is determined, the pin 32 passes through the threaded hole 185 on the side wall of the push head 182 to fix the plug 186. When the slide table 15 moves horizontally to the left, the hook 33 is hooked on the rotating shaft of the insulator test specimen 28. The force sensor 17 can measure the tension of the hook 33 on the rotating shaft or locking pin of the insulator test specimen 28.

[0084] from Figure 10 , 11 It can be seen that the end of the second rod 183 away from the push head 182 can be connected to the thrust test head 19 or the coating test head 34. When the end of the second rod 183 away from the push head 182 can be connected to the thrust test head 19, the right end face of the thrust test head 19 contacts the locking pin. When the slide table 15 moves horizontally to the right, the thrust test head 19 pushes the locking pin to move, and the force sensor 17 measures the thrust of the thrust test head 19.

[0085] like Figure 11 As shown, the installation method of the coating probe 34 is similar to that of the thrust test head 19. The coating probe 34 can be connected to the display device through the data cable 341 on it. First, adjust the height of the lead screw slide mechanism 2 so that the height of the coating probe 34 is at the position of the steel cap of the insulator test specimen 28, i.e., below the insulator test specimen 28. When the slide 15 moves horizontally to the right, the coating probe 34 contacts the steel cap of the insulator test specimen 28, and the coating probe 34 can perform coating measurement on the steel cap of the insulator test specimen 28. During coating measurement, a sleeve test structure 18 with spring buffer is selected, i.e., a spring is installed in the sleeve of the sleeve test structure 18 or in the push head 182. The spring is located between the push head 182 and the plug head 186. The spring can buffer the impact force of coating measurement. After the measurement of one measurement point is completed, the slide 15 moves horizontally to the left, the coating probe 34 separates from the steel cap, and drives the second tensioning mechanism 12 to rotate to the next measurement point. Repeat the above measurement process until all measurement points are completed.

[0086] For the force sensor 17 to measure the pulling force of the hook 33 on the locking pin, the pin 32 fixes the plug 186 and the push head 182 through the pin hole to prevent the plug 186 from coming out of the blind hole 184. For the pushing force of the locking pin on the thrust test head 19, or the pushing force of the insulator test specimen 28 on the coating test head 34, the plug 186 will not come out of the blind hole 184, so there is no need for the thrust screw or the pin 32.

[0087] Example 3

[0088] Based on Example 1, such as Figure 8As shown, both the first linkage mechanism 11 and the second linkage mechanism 8 adopt linkage mechanisms with conventional magnetic bases. The first linkage mechanism 11 and the second linkage mechanism 8 are magnetically attached to the top plate 5 and the housing 1 respectively by magnetic base 35. The installation of the two linkage mechanisms utilizes the light-receiving plate of the adjusting measuring rod 36 as an optical auxiliary measurement mechanism, which is convenient for installation, movement and adjustment, and can be conveniently used as a redundant measurement backup with a traditional dial indicator.

[0089] Specifically, the two-bar linkage mechanism has a measuring rod 36 and a sliding sleeve 37. The measuring rod 36 is clamped in the sliding sleeve 37. Adjusting the clamping position of the sliding sleeve 37 on the measuring rod 36 can adjust the clamping length of the measuring rod 36 on the sliding sleeve 37. The rotation of the sliding sleeve 37 can change the rotation of the light-receiving plate 13. The probe 351 is set on the measuring rod 36. The probe 351 can be used with a traditional dial indicator as a redundant measurement backup.

[0090] The distance between the first light-receiving plate 13a and the first laser rangefinder 10 can be adjusted by adjusting the first linkage mechanism 11, or the distance between the second light-receiving plate 13b and the second laser rangefinder 7 can be adjusted by adjusting the second linkage mechanism 8. The laser rangefinder calculates the distance between itself and the object being measured by measuring the laser light emitted from it, which is then reflected by the object being measured (the light-receiving plate) and received by the rangefinder. The rangefinder also records the round-trip time or reflection angle of the laser light, thus determining the distance between the rangefinder and the object being measured.

[0091] Example 4

[0092] Based on Example 1, such as Figure 1 , 5 As shown, based on Example 1, as Figure 1 , 5 As shown, the first tensioning mechanism 6 is combined with the second tensioning mechanism 12. During the test, the telescopic screw 61 of the first tensioning mechanism 6 extends or shortens to loosen or tighten the test insulator 28 in the vertical direction. The ball cage universal joint 121 can swing freely to a certain extent when the test insulator 28 is not clamped, so as to facilitate the clamping of the test specimen. After the insulator test specimen 28 is clamped and tightened, non-coaxial rotational transmission with uniformity can be realized.

[0093] The lifting adjustment mechanism 4 can be manually or electrically controlled to make the first lead screw 3 rotate in both directions to control the rise or fall of the slide mechanism 2. The first lead screw 3 and the nut 311 on the base plate 152 cooperate through the lead screw nut to make the entire lead screw slide mechanism 2 rise or fall together, and the slide 15 and the second lead screw 22 do not disengage from each other.

[0094] Both the lifting adjustment mechanism 4 and the first tensioning mechanism 6 adopt the meshing method of worm gear and worm. After the lifting adjustment mechanism 4 and the first tensioning mechanism 6 rotate to a specific position and stop, the lifting adjustment mechanism 4 and the first tensioning mechanism 6 can be self-locked and fixed.

[0095] Example 5

[0096] Based on the above embodiments 1-4, the lifting adjustment mechanism 4 can slide vertically to contact the guide column 151. The second lead screw 22 can be manually or electrically rotated to drive the thrust test head 19, the coating test head 34 or the hook 33 to move left and right in the horizontal direction. The threaded engagement between the second lead screw 22 and the slide table 15 realizes the locking when the thrust test head 19, the coating test head 34 or the hook 33 moves left and right. The slide table 15 only moves left and right when the second lead screw 22 rotates.

[0097] Example 6

[0098] Based on the above embodiments 1-5, in terms of shape and position parameter measurement, the structural height is measured by using the first digital measuring encoder 20a coaxially mounted on the first motor 21a of the first tensioning mechanism 6. That is, the telescopic screw 61 extends and pushes the insulator test specimen 28 down, so that the standard connecting cup 26 at the lower end of the first tensioning mechanism 6 is connected to the upper end of the second tensioning mechanism 12 and tightened. This is used as the reference position. Then the connection between the standard connecting cup 26 and the insulator test specimen 28 is loosened, and the insulator test specimen 28 is added and tightened again. During this process, the first digital measuring encoder 20a calculates the cumulative rotation angle data of the shaft of the first motor 21a and converts it into the displacement of the thrust in the vertical direction, thereby realizing the height measurement of the test specimen, i.e., the insulator 28.

[0099] In the figure, a laser rangefinder, namely the first laser rangefinder 10, is arranged horizontally. Its measuring beam is directed towards the light-receiving plate 13 of the horizontal auxiliary measuring device, namely the first light-receiving plate 13a of the first linkage mechanism 11. The size measurement is achieved by measuring the distance between the auxiliary measuring device or the first light-receiving plate 13a of the first linkage mechanism 11 and the first laser rangefinder 10.

[0100] Before the formal test, the first laser rangefinder 10 is used to suspend and measure the distance between the standard specimen and the rotating shaft of the insulator specimen 28. This value is then used to calibrate the reference distance.

[0101] After suspending the insulator test specimen, the first linkage mechanism 11 is used to place the first light-receiving plate 13a in the optical path of the first laser rangefinder 10 and to attach it to the outer peripheral wall of the insulator.

[0102] When the insulator test specimen 28 rotates, the radial deviation between the insulator test specimen 28 and the standard specimen can be obtained by using the distance test data between the first light-receiving plate 13a and the first laser rangefinder 10. The disc diameter value can be obtained by using the distance measurement data of the first laser rangefinder 10 and the aforementioned standard specimen reference distance calibration value and fitting it to a circle using the least squares method.

[0103] After the test specimen rotates one full turn, the radial deviation of the insulator test specimen 28 can be calculated by subtracting the minimum distance from the maximum distance between the first light-receiving plate 13a and the first laser rangefinder 10.

[0104] A second laser rangefinder 7 is arranged vertically, and its measuring beam is directed towards the second light-receiving plate 13b of the vertical auxiliary measuring device or the second linkage mechanism 8. The axial deviation of the insulator test specimen 28 is measured by measuring the distance between the second light-receiving plate 13b of the second linkage mechanism 8 and the second laser rangefinder 7. That is, the second light-receiving plate 13b of the second linkage mechanism 8 is attached to the outer end face of the insulator test specimen 28. The distance between the insulator test specimen 28 and the second light-receiving plate 13b of the second linkage mechanism 8 is measured first. After the insulator test specimen 28 rotates one revolution, the difference between the maximum and minimum measured distances is the axial deviation of the insulator test specimen 28.

[0105] The coating measurement is performed by rotating a taut insulator test specimen 28, with the coating probe 34 adhering to the outer peripheral wall of the insulator 28, and several test positions defined circumferentially on the outer peripheral wall of the insulator test specimen 28. After the insulator test specimen reaches the corresponding test position angle, the first rod 181 of the sleeve-type test head connecting structure 18 is extended from the sleeve, causing the coating probe 34 to adhere to the outer peripheral wall of the insulator 28 for coating testing. After the test is completed, the first rod 181 is retracted, the test specimen is rotated to the next test point, and the above process is repeated until all tests are completed.

[0106] Pre-test calibration of standard rotating shaft and rangefinder

[0107] The standard specimen is tensioned by the first tensioning mechanism 6 in the tensioned state. Its outer diameter has been measured in advance and is known data. During calibration, the distance between its outer diameter and the first laser rangefinder 10 is measured as the reference value. The length deviation introduced by the linkage mechanism, light receiving plate, etc. can be calculated. Subsequent measurements can be based on this data for compensation calculation.

[0108] Screw slide mechanism

[0109] The lead screw slide mechanism 2 is a structure of the prior art. In this invention, a nut 311 is connected to the side or top of the base plate 152 of the lead screw slide mechanism 2. The first lead screw 3 passes through the slide 152 and the nut 311. The first lead screw 3 and the nut 311 are connected by a thread. The first lead screw 3 is separated from the base plate 152. The rotation of the first lead screw 3 causes the entire lead screw slide mechanism 2 to move up and down together.

[0110] Telescopic rod front sleeve type slide rail mechanism

[0111] The rear end of the sleeve-type test head connection structure 18 is connected to the threaded hole structure of the force sensor 17 through the external thread of the first rod 181. The front end adopts a sleeve slide rail method, that is, the push head 182 and the plug head 186 are slidably inserted. This structure can facilitate the replacement of the thrust test head 19, the coating test head 34, or the hook 33. The front end of the push head 182 adopts a stepped cylindrical shape with a thicker front and a thinner rear as the second rod 183, which is integrally formed with the push head 182. When using the thrust test head 19, the hook 33 for tensile force measurement, and the coating test head 34, the push head 182 and the plug head 186 are slidably inserted. After the plug head 186 is fitted into the push head 182, the pin 32 is inserted into the side of the push head 182 to lock it, thereby locking all the probes and performing measurements.

It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
