Description

Technical Field

[0001] The invention relates to the technical field of laser measuring devices, in particular to a laser measuring device for the linear dimensions of a composite insulator. Background Art

[0002] Composite insulators can be divided into: line composite insulators and power station and electrical appliance composite insulators; they can also be divided into rod-type suspension composite insulators, pin-type composite insulators, cross-arm composite insulators, pillar composite insulators, wind-proof composite insulators, etc. Insulators play two basic roles in overhead transmission lines, namely supporting the conductors and preventing current from returning to the ground;

[0003] The existing patent publication number CN118936320A discloses a device and method for measuring the external dimensions of a rod-shaped composite insulator, which comprises: a housing, a light source, an image processing device, and a movable image acquisition device disposed in the housing; wherein a sample fixing member is disposed in the housing for connecting to the composite insulator to be measured; the light source is located on one side of the sample fixing member for causing the composite insulator to be measured to generate a projection image; the movable image acquisition device is disposed on the other side of the sample fixing member for acquiring a projection image of the surface of the composite insulator to be measured; the image processing device is connected to the movable image acquisition device. The movable image acquisition device is provided in the housing to acquire the projected image of the composite insulator to be tested, and the image processing device is used to analyze and process the acquired insulator projection image to determine the insulation distance, umbrella diameter, umbrella spacing and creepage distance of the insulator, thereby realizing fully automatic measurement of the insulator's external dimension parameters, reducing the occurrence of human measurement errors and human intervention, and greatly improving the accuracy and effectiveness of the measurement results.

[0004] However, in the actual measurement process, due to the different types and shapes of composite insulators, when measuring the dimensions of composite insulators, in order to reduce the measurement error, it is necessary to ensure that the position of the composite insulator remains fixed during the measurement process. At the same time, the shape of the end of the composite insulator varies with the type. When measuring the dimensions, the clamping method of the end of the composite insulator with different shapes also needs to be changed accordingly.

[0005] To solve this problem, we propose a composite insulator linear dimension laser measurement device. Summary of the Invention

[0022] Beneficial effects

[0023] Compared with the prior art, the present invention provides a composite insulator linear dimension laser measurement device, which has the following beneficial effects:

[0024] The arc-shaped gear ring and arc-shaped limit frame can adapt to the surface clamping of composite insulators with different terminal shapes. They can closely fit terminals of different shapes, allowing the composite insulator to maintain a stable position and posture during the measurement process, preventing it from shaking or shifting, thereby ensuring the accuracy and repeatability of laser measurement. For example, even insulators with irregular terminals can be accurately positioned to avoid measurement errors caused by position changes. In addition, it can adapt to various shapes and specifications of composite insulator terminals, whether round, square or other special-shaped terminals, and can achieve reliable clamping, meeting diverse measurement needs and improving the application range and versatility of the clamping device.

[0025] Through the cooperation between the supporting semicircular ring and the clamping piece, when clamping the edge of the irregular composite insulator, it is only necessary to apply the clamping force above the two ends of the composite insulator. The supporting semicircular ring itself will form an upward supporting force on the lower end of the composite insulator. The edge of the irregular composite insulator may be uneven or asymmetrical in shape. The arc design of the supporting semicircular ring can fit the contour of its lower end, providing stable support, avoiding unstable clamping caused by shape mismatch. The supporting semicircular ring provides an upward supporting force from the bottom, which forms a balance with the clamping force of the upper clamping piece, effectively preventing the insulator from tilting or flipping during the clamping process, and ensuring the reliability of the clamping posture. In addition, applying the clamping force only from the top may cause uneven force on the irregular edge, or even crush the surface of the insulator. The supporting force of the supporting semicircular ring disperses the pressure from the bottom, avoids local stress concentration, and protects the edge of the composite insulator from damage.

[0026] The laser spotlight and guide holes ensure that the center of the clamping assembly is horizontal before use. This horizontal state is essential for accurate measurement or processing. The combination of the laser spotlight and guide holes ensures that the clamping assembly is horizontal during installation or adjustment, avoiding measurement deviations or processing errors caused by tilt. In addition, in batch production or repeated measurements, maintaining the horizontal state of the clamping assembly ensures consistent conditions for each operation, reducing errors caused by changes in equipment status.

[0027] The bidirectional threaded rod can be used to clamp composite insulator ends of different lengths. The design of the bidirectional threaded rod and the clamping assembly can achieve symmetrical and uniform clamping force, avoiding deformation or damage of the insulator end due to unilateral force.

[0028] By setting up the supporting semicircular ring, when clamping the two ends of the composite insulator, the position of the composite insulator is quickly restricted, so that it can be quickly clamped by cooperating with the clamping component. By pre-positioning the supporting semicircular ring, the clamping component only needs to apply appropriate clamping force to fix the composite insulator, reducing friction and wear caused by repeated adjustments and extending the service life of the composite insulator end.

[0057] Further embodiments

[0058] See also Figure 3 and Figure 9 , the composite insulator linear dimension laser measuring device further includes a support assembly provided on the guide rod 32;

[0059] The support assembly includes positioning rings 51 that are respectively slidably connected to the outer surfaces of the two ends of the two guide rods 32. The outer surfaces of the positioning rings 51 are fixedly connected to the tilting links 52. A short link 53 is fixedly connected between the outer surfaces of the two tilting links 52 on the same side away from the positioning rings 51. A supporting semi-circular ring 54 is fixedly connected at the center of the top of the short link 53. A long link 55 is fixedly connected between the middle parts of the two tilting links 52 on the same side.

[0060] Among them, the two inclined connecting rods 52 on the same side are arranged axially symmetrically with respect to the vertical plane where the bidirectional threaded rod 33 is located, and the center of the supporting semicircular ring 54 and the center of the arc-shaped gear ring 2091 are in the same horizontal plane.

[0061] The outer surface of the positioning ring 51 is fixedly connected to the sliding support 21 .

[0062] The working process and principle of the above embodiment are as follows:

[0063] Movement of the sliding support 21:

[0064] The staff moves the distance between the two sliding supports 21 according to the size of the composite insulator to be measured. At this time, the staff turns on the stepper motor 35 through the external control device. At this time, the bidirectional threaded rod 33 fixedly connected to the output shaft end of the stepper motor 35 will rotate accordingly. Since the threads at the two ends of the bidirectional threaded rod 33 are in opposite directions, the driven swivel rings 34 threadedly connected to the outer surfaces of the two ends of the bidirectional threaded rod 33 will approach each other under the action of the bidirectional threaded rod 33 and gradually move toward the center of the bidirectional threaded rod 33, that is, the direction of the positioning support 31.

[0065] During the above process, since the sliding support 21 is slidably connected to the outer surface of the guide rod 32, a through groove having a size adapted to the driven swivel 34 is formed through the center of the sliding support 21, and the driven swivel 34 is rotatably connected to the through groove of the sliding support 21, as the bidirectional threaded rod 33 rotates and the driven swivel 34 moves, the two sliding supports 21 respectively provided at both ends of the support frame 11 will approach each other on the surface of the guide rod 32 and the support frame 11 in the direction of the positioning support 31, thereby adjusting the distance between the clamping components through the sliding supports 21 to adapt to composite insulators of different lengths;

[0066] It should be noted that, in the above process, since the positioning ring 51 is slidably connected to the outer surface of the guide rod 32, and the outer surface of the positioning ring 51 is fixedly connected to the sliding support 21, as the sliding support 21 moves, the positioning ring 51 will also move accordingly. At this time, the long connecting rod 55, the short connecting rod 53, the inclined connecting rod 52 and the supporting semi-circular ring 54 connected to the positioning ring 51 will also move synchronously.

[0067] The bidirectional threaded rod 33 can be used to clamp composite insulator ends of different lengths. The design of the bidirectional threaded rod 33 and the clamping assembly can achieve symmetrical and uniform clamping force, thus avoiding deformation or damage of the insulator end due to unilateral force.

[0068] The support semicircular ring 54 is provided to quickly limit the position of the composite insulator when clamping the two ends of the composite insulator, thereby cooperating with the clamping assembly to quickly clamp it. With the pre-positioning of the support semicircular ring 54, the clamping assembly only needs to apply appropriate clamping force to fix the composite insulator, thereby reducing friction and wear caused by repeated adjustments and extending the service life of the composite insulator end.

[0069] As the two sliding supports 21 move to the predetermined position, the staff turns off the stepper motor 35 through the external controller. At this time, the staff turns on the laser spotlight 42 on the positioning rod 41, and the laser spotlight 42 emits straight rays. Since there are two sets of clamping components on the sliding support 21, and in the initial state, the centers of the two arc-shaped gear rings 2091 on each sliding support 21, the center of the laser spotlight 42, and the guide hole 44 are in the same plane, after turning on the laser spotlight 42, when the laser spotlight 42 is projected onto the projection platform 45 through the guide hole 44, the clamping centers of the clamping components on the two sliding supports 21 are in the same horizontal plane.

[0070] The laser spotlight 42 and guide hole 44 ensure that the center of the clamping assembly is horizontal before the device is used. This horizontal state is essential for accurate measurement or processing. The combination of the laser spotlight 42 and guide hole 44 ensures that the clamping assembly is horizontal during installation or adjustment, avoiding measurement deviations or processing errors caused by tilt. Furthermore, in batch production or repeated measurements, maintaining the horizontal state of the clamping assembly ensures consistent conditions for each operation, reducing errors caused by changes in equipment status.

[0071] It should be noted that the laser spotlight 42 and the guide hole 44 are respectively located on the two sliding supports 21, and in the initial state are respectively located at the clamping centers of the two sets of clamping assemblies provided on the two sliding supports 21, so as to keep the composite insulator as a whole in a horizontal state when the two sets of clamping assemblies clamp the end points of the composite insulator;

[0072] Subsequently, the staff placed the composite insulator to be tested on the two supporting semicircular rings 54. At this time, the two supporting semicircular rings 54 supported both ends of the composite insulator to be tested and ensured that the composite insulator to be tested was in a horizontal state, facilitating the subsequent clamping of both ends of the composite insulator, thereby ensuring the accuracy of the test data.

[0073] Clamping of different types of composite insulators at both ends:

[0074] When clamping the composite insulator, for the composite insulator with cylindrical ends, the staff starts the driving cylinder 25 through the external controller, so that the output shafts at both ends of the driving cylinder 25 extend upward or downward respectively. At this time, the clamping members 26 connected to the output shafts at both ends of the driving cylinder 25 are rotated and move accordingly. Since the clamping member 26 is arranged in a zigzag shape, the clamping member 26 is rotated and connected to the outer surface of the positioning plate 24 away from the corner point of one end of the output shaft of the driving cylinder 25. Therefore, as the output shaft of the driving cylinder 25 moves, the clamping member 26 will rotate with its connection point with the positioning plate 24 as a fulcrum. At this time, the rubber contact member 27 located at the end of the clamping member 26 away from the driving cylinder 25 will move accordingly until it contacts the outer surfaces of the two ends of the composite insulator to be tested.

[0075] It should be noted that, in the above process, since the clamping assemblies are symmetrically arranged on the two sliding supports 21, only one group is described here, and the movement steps of the other group are the same as the above steps. In addition, the two driving cylinders 25 in each group of clamping assemblies move synchronously, so that the two groups of eight rubber abutments 27 located at both ends of the composite insulator abut against the outer surface of the composite insulator, thereby fixing the two ends of the composite insulator. At the same time, the above-mentioned clamping member 26 compresses the buffer spring 28 disposed between its outer surface and the positioning plate 24 during the movement process, thereby preventing the clamping member 26 and the rubber abutment 27 from clamping the composite insulator with excessive force, which may cause damage to the composite insulator.

[0076] For composite insulators with rectangular cross-sections at both ends, the staff starts the drive motor 2093 through the external controller. At this time, the drive gear 2092 fixedly connected to the output shaft of the drive motor 2093 will rotate accordingly. The drive gear 2092 meshes with the arc-shaped ring gear 2091, causing the arc-shaped ring gear 2091 to rotate inside the arc-shaped limit frame 23.

[0077] Since there are two arc-shaped ring gears 2091, drive motors 2093, drive gears 2092 and arc-shaped limit frames 23 symmetrically arranged on each sliding support 21, during the above process, the two drive motors 2093 located on the same sliding support 21 will move in the same manner under the action of the external controller, so that the arc-shaped ring gears 2091 fixed by the two drive motors 2093 move in opposite directions in the arc-shaped limit frame 23. Specifically, one of the arc-shaped ring gears 2091 moves upward around the center of the clamping assembly in the arc-shaped limit frame 23, and the other arc-shaped ring gear 2091 moves downward around the center of the clamping assembly in the arc-shaped limit frame 23.

[0078] It should be noted that the symmetric centers of the two arc-shaped gear rings 2091 on the same sliding support 21, the symmetric center of the arc-shaped limit frame 23, and the clamping center of the clamping assembly are all at the same position;

[0079] As the arc-shaped gear ring 2091 moves, the positioning plate 24 fixedly connected to the arc-shaped gear ring 2091 will move around the center of the clamping assembly until the clamping member 26 located above one of the positioning plates 24 moves to the center above the clamping assembly, and the clamping member 26 located below the other positioning plate 24 moves to the center below the clamping assembly. At this time, only the above two clamping members 26 are located on the upper and lower sides of the composite insulator to be inspected, thereby clamping both ends of the composite insulator. The clamping process is synchronized with the movement process of the clamping member 26 driven by the motor 2093 according to the above steps, so it will not be described in detail here.

[0080] For clamping composite insulators with irregular cross sections at both ends:

[0081] In the initial state, the two arc-shaped gear rings 2091 on the two sliding supports 21 are symmetrically arranged. Therefore, when clamping this type of composite insulator, the staff needs to start the drive motor 2093 again, and drive the drive gear 2092 to rotate through the drive motor 2093, thereby driving the arc-shaped gear ring 2091 to rotate inside the arc-shaped limit frame 23;

[0082] The difference from the above process is that in this case, the output shafts of the two drive motors 2093 need to rotate in opposite directions, that is, the two arc-shaped gear rings 2091 are moved upward or downward simultaneously inside the arc-shaped limit frame 23. Moreover, due to the provision of the supporting semicircular ring 54, the supporting semicircular ring 54 supports the bottom of the composite insulator to be inspected, so the two arc-shaped gear rings 2091 need to slide upward along the clamping center inside the arc-shaped limit frame 23.

[0083] As the arc-shaped gear ring 2091 moves, the two clamping members 26 located above the two positioning plates 24 will gradually approach each other, and the two clamping members 26 located below the two positioning plates 24 will gradually move away from each other. Therefore, when the edge of the composite insulator is subsequently clamped by driving the cylinder 25 and the clamping members 26, the rubber abutment members 27 provided on the outer surfaces of the two clamping members 26 located above the two positioning plates 24 will contact the top of the composite insulator, thereby applying a clamping force to the composite insulator from above and cooperating with the supporting semicircular ring 54 to fix the position of the composite insulator. The two groups of clamping components located at both ends of the composite insulator move synchronously, thereby avoiding an unbalanced state of the composite insulator during the clamping process.

[0084] By cooperating with the supporting semicircular ring 54 and the clamping piece 26, when clamping the edge of the irregular composite insulator, it is only necessary to apply a clamping force above the two ends of the composite insulator. The supporting semicircular ring 54 itself will form an upward supporting force on the lower end of the composite insulator. The edge of the irregular composite insulator may be uneven or asymmetrical in shape. The arc design of the supporting semicircular ring 54 can fit the contour of its lower end, providing stable support, and avoiding unstable clamping caused by shape mismatch. The supporting semicircular ring 54 provides an upward supporting force from the bottom, which forms a balance with the clamping force of the upper clamping piece 26, effectively preventing the insulator from tilting or flipping during the clamping process, and ensuring the reliability of the clamping posture. In addition, applying a clamping force only from the top may cause uneven force on the irregular edge, or even crush the surface of the insulator. The supporting force of the supporting semicircular ring 54 disperses the pressure from the bottom, avoids local stress concentration, and protects the edge of the composite insulator from damage.

[0085] Dimensional measurements of composite insulators:

[0086] After the composite insulator is fixed in position, the staff starts the electric-controlled slide rail 12 and the laser measuring instrument 13, so that the laser measuring instrument 13 moves from one end of the electric-controlled slide rail 12 to the other end, thereby transmitting the dimensional information of the composite insulator to be inspected to the external signal receiving device through the laser measuring instrument 13;

[0087] It should be noted that the horizontal movement of the laser measuring instrument 13 on the electric control slide rail 12 and the detection of the composite insulator by the laser measuring instrument 13 are both existing technologies, so they will not be described in detail here.

[0088] By setting up the arc-shaped gear ring 2091 and the arc-shaped limit frame 23, the surface clamping of composite insulators with different end shapes can be adapted, and the ends of different shapes can be tightly fitted, so that the composite insulator maintains a stable position and posture during the measurement process to prevent it from shaking or shifting, thereby ensuring the accuracy and repeatability of the laser measurement. For example, even insulators with irregular ends can be accurately positioned to avoid measurement errors caused by position changes. In addition, it can adapt to composite insulator ends of various shapes and specifications, whether they are round, square or other special-shaped ends, and can achieve reliable clamping, meeting diverse measurement needs and improving the application range and versatility of the clamping device.
