Description

Technical Field

[0001] This invention belongs to the field of insulator measurement, specifically a disc-shaped suspension porcelain insulator measuring device and method. Background Technology

[0002] An insulator typically consists of an insulating post and multiple large and small skirts installed alternately on the post. In a standard disc-type suspension porcelain insulator, the distance between adjacent skirts is the same, and all large and small skirts have the same diameter. The skirts at both ends are large skirts. When insulators leave the factory, they undergo a quality inspection. This inspection typically involves measuring the skirt diameter and the distance between adjacent skirts. This is usually done using a laser rangefinder and a measuring ruler. The laser rangefinder measures the skirt diameter, and the measuring ruler measures the distance between adjacent skirts. However, the following defects still exist: When inspecting the diameter of the umbrella skirts, the laser rangefinder needs to be moved to the bottom of each umbrella skirt one by one for inspection, which results in low inspection efficiency. At the same time, it is impossible to simultaneously inspect the skirt spacing for compliance, which also results in low inspection efficiency. Summary of the Invention

[0013] Preferably, a measurement method for a disc-shaped suspension porcelain insulator measuring device is as follows: S1. Clamping and fixing: The insulator is centered and clamped by two insulator clamping mechanisms; S2, Position Correspondence: The moving detection mechanism is installed on the guide rail. The middle laser rangefinder is aligned with the end small umbrella skirt position through the umbrella skirt positioning component and the middle laser rangefinder. The two sliding tables are moved by the first motor so that the two side laser rangefinders are aligned with the two large umbrella skirt positions. S3.

[0014] Compared with the prior art, the beneficial effects of the present invention are: (1) In this invention, the central laser rangefinder corresponds to the position of the small umbrella skirt, and the two side laser rangefinders correspond to the position of the large umbrella skirt. The horizontal platform plate is driven to rotate by using the side laser rangefinder at one end as the axis of rotation, so that the horizontal platform plate moves along the guide rail. After rotation, the central laser rangefinder and the side laser rangefinders can correspond to the positions of the other small umbrella skirts and the large umbrella skirts respectively, so that it is not necessary to pass through each large umbrella skirt and each small umbrella skirt in sequence, and then pass through the two umbrella skirts in one go, thereby improving the detection efficiency. (2) In this invention, the bottom box corresponds to the position of the central laser rangefinder, and the movable plate inside the bottom box is connected to two sliding tables by two connecting rods respectively. By driving the movable plate to move longitudinally, the two side laser rangefinders can be pulled to move relative to each other to adjust their positions, which is convenient for detecting insulators with different skirt spacings. (3) In this invention, the distance between the edges of the small umbrella skirt is measured by the central laser rangefinder and the distance between the edges of the large umbrella skirt is measured by the side laser rangefinder. Before the test, the distance between the outer walls of the insulating column of the insulator is measured by the central laser rangefinder. Based on the diameter of the insulating column of the insulator, the diameter of the large and small umbrella skirts can be measured. At the same time, during the test, the central laser rangefinder is always aligned with the small umbrella skirt and the side laser rangefinder is always aligned with the large umbrella skirt, ensuring the continuity of the test results. When other data appears, it indicates that there is a defective insulator. This makes it convenient to test the passability of the distance between two adjacent umbrella skirts when testing the diameter of the umbrella skirt. (4) In this invention, the bottom plate on one side is fixed with the guide rail by negative pressure, while the bottom plate on the other side is raised upward, so that the platform plate is supported by the support box on one side and rotated by the rotating motor on this side to move forward. By continuously changing the support box, it can move forward continuously, which is convenient to use. (5) In this invention, before the piston support block moves downward, the partition baffle separates the negative pressure groove, so that negative pressure is generated in the negative pressure groove. After the bottom plate is in close contact with the inner bottom wall of the guide slide rail, the partition baffle moves back, so that negative pressure is generated between the negative pressure cavity and the guide slide rail, thereby achieving negative pressure fixation. When it is necessary to lift, the partition baffle is driven to move towards the second electromagnet, so that the negative pressure cavity is connected to the outside through the connecting groove, which facilitates the release of negative pressure and lifting.

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] Example 1, by Figures 1-7 The present invention relates to a disc-shaped suspension porcelain insulator measuring device, comprising a workbench 1, an insulator clamping mechanism 2 symmetrically mounted on the top of the workbench 1, the two insulator clamping mechanisms 2 being used to clamp insulators between each other, and a moving detection mechanism 4 provided on the top of the workbench 1.

[0019] The insulator clamping mechanism 2 includes two fixed frames 201 symmetrically installed on the top of the workbench 1. Each of the two fixed frames 201 is provided with a centering clamping cylinder 202 on one side close to each other. The centering clamping cylinder 202 is fixedly connected to the output end of the clamping cylinder 203. The clamping cylinder 203 is fixedly installed on the side of the fixed frame 201 away from the centering clamping cylinder 202.

[0020] The top of the workbench 1 is equipped with a guide rail 3, which consists of two limit baffles. A guide groove is formed between the two limit baffles, and the moving detection mechanism 4 is set in the guide groove.

[0021] The mobile detection mechanism 4 includes a platform plate 401. A central laser rangefinder 402 is installed at the top center of the platform plate 401. Two sliding grooves 403 are formed on the platform plate 401, symmetrically arranged on both sides of the central laser rangefinder 402. A sliding table 404 is slidably installed inside the sliding groove 403. A side laser rangefinder 405 is installed at the top of the sliding table 404. The central laser rangefinder 402 corresponds to the position of the small umbrella skirt, and the two side laser rangefinders 405 correspond to the positions of the large umbrella skirt. The platform plate 401 is driven to rotate by using one of the side laser rangefinders 405 as the pivot point, so that the platform plate 401 moves along the guide rail 3. After rotation, the central laser rangefinder 402 and the side laser rangefinders 405 can correspond to the positions of the other small umbrella skirt and the large umbrella skirt, respectively. This eliminates the need to sequentially pass through each large and small umbrella skirt before passing through two skirts at a time, thus improving inspection efficiency. A relative moving component 406 is installed between the two sliding tables 404, and a bottom support component 408 is installed at the bottom of the sliding tables 404. The central laser rangefinder 402 measures the distance between the edges of the small umbrella skirts, and the side laser rangefinder 405 measures the distance between the edges of the large umbrella skirts. Before inspection, the central laser rangefinder 402 measures the distance between the outer walls of the insulator's insulating column and, based on the diameter of the insulator's insulating column, can measure the diameters of the large and small umbrella skirts. During the inspection process, the central laser rangefinder 402 always corresponds to the small umbrella skirt, and the side laser rangefinder 405 always corresponds to the large umbrella skirt, ensuring the continuity of the inspection results. When other data appears, it indicates that the insulator is unqualified.

[0022] The relative moving component 406 includes a bottom box 4061 fixedly installed at the center of the bottom end of the platform plate 401. Side grooves 4062 are symmetrically formed on both sides of the bottom box 4061. A movable plate 4063 is slidably installed inside the bottom box 4061.

The end is fixedly connected to the output shaft of the first motor 4065. The first motor 4065 is fixedly installed at the bottom of the bottom box 4061. The bottom box 4061 corresponds to the position of the central laser rangefinder 402. The movable plate 4063 inside the bottom box 4061 is connected to two sliding tables 404 respectively through two connecting rods 4066. By driving the movable plate 4063 to move longitudinally, the two side laser rangefinders 405 can be pulled to move relative to each other for position adjustment, which is convenient for detecting insulators with different skirt spacing. The bottom box 4061 is provided with a skirt positioning component 4067.

[0023] The umbrella skirt positioning component 4067 includes two symmetrically opened limiting grooves 40671 inside the bottom box 4061. The two limiting grooves 40671 are located on both sides of the bottom box 4061 where the side grooves 4062 are not opened. A limiting plate 40672 is movably installed inside the limiting groove 40671. A top rod 40673 is fixedly installed at the top of the limiting plate 40672. The top of the top rod 40673 extends through to the top of the platform plate 401. A V-shaped positioning frame 40674 is fixedly installed at the top of the top rod 40673. A first magnetic block 40676 is fixedly installed at the bottom of the limiting plate 40672. A first electromagnet 40675 is fixedly installed on the inner bottom wall of the limiting groove 40671.

[0024] The bottom support assembly 408 includes a support box 4081 disposed below the sliding table 404. A limiting cylinder 4083 is fixedly installed at the bottom end of the sliding table 404. A fixed shaft 4082 is fixedly installed at the top end of the support box 4081. The fixed shaft 4082 is rotatably installed inside the limiting cylinder 4083. A gear ring 4084 is installed on the outside of the limiting cylinder 4083. A gear 4085 is meshed on one side of the gear ring 4084.

[0025] The bottom lifting component 4087 includes an internal groove 40871 formed inside the support box 4081. A piston support block 40872 is movably installed inside the internal groove 40871. A base plate 40873 is fixedly installed at the bottom end of the piston support block 40872. The two sides of the base plate 40873 contact two limiting baffles. Two fixing plates 40874 are fixedly installed on one side of the support box 4081. A longitudinal sliding plate 40875 is provided between the two fixing plates 40874. A connecting rod 40876 is fixedly installed between the bottom end of the longitudinal sliding plate 40875 and the base plate 40873. The connecting rod 40876 is slidably connected to the fixing plate 40874 below. The two fixing plates 40874 can rotate. A second screw 40877 is installed, which is threadedly connected to the longitudinal plate 40875. The top end of the second screw 40877 is fixedly connected to the output shaft of the second motor 40878. The second motor 40878 is fixedly installed on the top end of the fixed plate 40874. A fixed separation component 4088 is provided inside the base plate 40873. One side of the base plate 40873 is fixed to the guide slide rail 3 under negative pressure, while the other side of the base plate 40873 is lifted upward, so that the horizontal platform plate 401 is supported by a support box 4081 on one side and rotated by a rotating motor 4086 on this side to move forward. By continuously changing the support box 4081, it can move forward continuously, which is convenient to use.

[0026] The fixed separation component 4088 includes a negative pressure chamber 40882 formed inside the base plate 40873. The bottom end of the negative pressure chamber 40882 extends to the bottom end of the base plate 40873. A negative pressure groove 40881 is formed at the top end of the negative pressure chamber 40882, and the top end of the negative pressure groove 40881 extends to the top end of the piston support block 40872. A partition groove 40884 is formed inside the base plate 40873, and the partition groove 40884 communicates with the negative pressure groove 40881. A storage groove 40 is formed at one end of the partition groove 40884. 883, the width of the storage slot 40883 is greater than the width of the partition slot 40884. An inner plate 40885 is slidably installed inside the storage slot 40883. A partition baffle 40886 is fixedly installed on the side of the inner plate 40885 near the partition slot 40884. Return springs 40887 are symmetrically installed on the side of the inner plate 40885 near the partition slot 40884. One end of the return spring 40887 is fixedly connected to the inner wall of the end of the storage slot 40883 near the partition slot 40884. A second magnet 40888 is installed on plate 40885. A second electromagnet 40889 is installed on the inner wall of the end of the storage groove 40883 away from the dividing groove 40884. The upper and lower inner walls of the dividing groove 40884 are provided with connecting grooves 408810. The two connecting grooves 408810 are respectively connected to the negative pressure chamber 40882 and the top of the bottom plate 40873. The connecting grooves 408810 are located on the side of the negative pressure groove 40881 near the storage groove 40883. The piston support block 40872 moves downward. Beforehand, the partition baffle 40886 separates the negative pressure groove 40881, creating negative pressure in the negative pressure groove 40881. After the bottom plate 40873 is in close contact with the inner bottom wall of the guide slide rail 3, the partition baffle 40886 moves back, creating negative pressure between the negative pressure cavity 40882 and the guide slide rail 3, thus achieving negative pressure fixation. When it is necessary to lift, the partition baffle 40886 is driven to move towards the second electromagnet 40889, so that the negative pressure cavity 40882 is connected to the outside through the connecting groove 408810, making it convenient to release the negative pressure and lift.

[0027] Working principle: When in use, the insulator is clamped between two insulator clamping mechanisms 2. Multiple large and small umbrella skirts are installed alternately on the insulator. The distance between two adjacent umbrella skirts of a standard disc suspension porcelain insulator is the same. At the same time, the diameter of each large umbrella skirt is the same and the diameter of each small umbrella skirt is the same. The umbrella skirts at both ends are large umbrella skirts. During clamping, the two clamping cylinders 203 are activated, and the two centering clamping cylinders 202 are pushed closer to each other to coaxially clamp the insulator, so that the centerline of the insulator is directly above the centerline of the guide rail 3, thus completing the clamping and fixing. Then, the moving detection mechanism 4 is placed inside the guide slide rail 3. After placement, the two base plates 40873 on the moving detection mechanism 4 contact the inner walls on both sides of the guide slide rail 3 to complete the limiting. The bottom of the base plate 40873 is provided with a sealing gasket. At the same time, the inner bottom wall of the guide slide rail 3 is smoothly set, pushing the moving detection mechanism 4 to move along the guide slide rail 3, so that the middle laser rangefinder 402 moves to the position below the end small umbrella skirt. The first electromagnet 40675 is energized, so that the first electromagnet 40675 generates a repulsive force on the first magnetic block 40676, pushing the V-shaped positioning frame 40674 to move upward, so that the V-shaped positioning frame 40674 moves to the bottom of the small umbrella skirt to complete the positioning. At this time, the middle laser rangefinder 402 corresponds to the edge position of the small umbrella skirt, and the distance A from the middle laser rangefinder 402 to the edge position of the small umbrella skirt is detected. Then, the first motor 4065 is turned on, driving the first screw 4064 to rotate. The first screw 4064 is threadedly connected to the movable plate 4063, thereby driving the movable plate 4063 to move longitudinally along the bottom box 4061. This causes the two sliding tables 404 to move relative to each other along the sliding groove 403 via the two connecting rods 4066, adjusting the two side laser rangefinders 405 to the lower position corresponding to the large umbrella skirts on both sides, and detecting the distance B from the side laser rangefinders 405 to the edge of the large umbrella skirt. Before testing, the radius C of the insulating post of the insulator is measured, and the distance D from the central laser rangefinder 402 to the outer wall of the insulating post is measured. The central laser rangefinder 402 and the side laser rangefinder 405 are at the same height, thus the following results can be obtained: The radius of the large umbrella skirt is D-B+C, and the radius of the small umbrella skirt is D-A+C; After the position is determined, the second motor 40878 on the support box 4081 on the side away from the end umbrella skirt is turned on, driving the second screw 40877 to rotate, thereby causing the base plate 40873 to move upward. Then, the second electromagnet 40889 inside is energized, generating a repulsive force on the second magnetic block 40888, pushing the partition baffle 40886 to move outward to isolate the negative pressure groove 40881. Then, it is controlled to move downward until the base plate 40873 is reached. The bottom wall of 3 is in close contact with the inner bottom wall of the guide slide rail 3. During the movement, a negative pressure is generated in the negative pressure groove 40881. Then, the second electromagnet 40889 is de-energized, so that the partition baffle 40886 moves back under the elastic force of the return spring 40887, so that the negative pressure cavity 40882 is connected with the negative pressure groove 40881, and then a negative pressure is generated in the negative pressure cavity 40882, which in turn causes the bottom plate 40873 to be negatively attracted and fixed to the inner bottom wall of the guide slide rail 3. Then, the second motor 40878 on the support box 4081 near the end of the umbrella skirt is activated, driving the piston support block 40872 to move upward. Then, the rotating motor 4086 on the support box 4081 away from the end of the umbrella skirt is activated, driving the gear 4085 to rotate. The gear 4085 meshes with the gear ring 4084, thereby driving the sliding table 404 to rotate. The sliding table 404 is slidably installed in the sliding groove 403, thereby driving the horizontal platform plate 401 to rotate 180 degrees around the fixed shaft 4082. Then, the piston support block 40872 on the other support box 4081 is driven to move downward until the bottom wall of the bottom plate 40873 contacts the inner bottom wall of the guide rail 3. Following the above operations, the following four steps are repeated: the support box 4081 on the side away from the umbrella skirt is fixed with negative pressure to the guide rail 3; the base plate 40873 on the support box 4081 on the side close to the umbrella skirt is lifted upward; the horizontal platform plate 401 rotates 180 degrees around the fixed shaft 4082 on the side away from the umbrella skirt; and the two base plates 40873 are supported again. When the base plate 40873 needs to be lifted, the second electromagnet 40889 is energized to attract the second magnetic block 40888, causing the partition baffle 40886 to move toward the side of the second electromagnet 40889. This allows the negative pressure chamber 40882 to connect with the outside through the connecting groove 408810, thereby relieving the negative pressure between the negative pressure chamber 40882 and the guide rail 3, making it easier for the base plate 40873 to be lifted upward. During the continuous movement, the mobile detection mechanism 4 moves from under one end of the insulator to under the other end. The distance between adjacent sheds of a standard insulator is the same, and the diameters of all large sheds and small sheds are the same. This ensures that the detection data of the central laser rangefinder 402 and the side laser rangefinder 405 remain unchanged at each detection position during the movement. If the detection data changes, it indicates that there are problems such as inconsistent shed spacing, non-standard shed diameter, or stains on the shed edges, indicating that the insulator is not up to standard.
