Description

Technical Field

[0001] This invention relates to the field of insulator processing technology, specifically to a glazing device for manufacturing ultra-high voltage insulators. Background Technology

[0002] Ultra-high voltage insulators are the core insulation components of power transmission and transformation lines. They are mainly made of ceramic / electric porcelain materials. The uniformity, density, and thickness consistency of the glaze layer on the surface directly determine the insulation strength, anti-pollution flashover performance, aging resistance and operational reliability of the product. In the glazing process, the ceramic insulator blank has extremely high requirements for the fluidity, adhesion uniformity and glazing stability of the glaze. Defects in the glaze layer can easily cause safety hazards such as insulator breakdown and pollution flashover. For example, patent CN220232833U discloses a novel glazing machine for producing ultra-high voltage insulators, belonging to the field of glazing machines. This novel glazing machine for producing ultra-high voltage insulators includes a base and left and right support frames symmetrically arranged on the left and right sides of the base, respectively. The left and right support frames have sliding grooves, and support plates are slidably connected to the two grooves. A motor is installed above the support plates, and the output end of the motor passes through the support plates and is connected to the glazing assembly. A glazing tank is fixedly installed above the base, and a mixing assembly is installed in the glazing tank. A cylinder is fixedly installed on the left support frame, and the extension rod of the cylinder is fixedly connected to the lower left side of the support plate. This design can prevent the glaze from not flowing in the glazing tank, thus avoiding glaze sedimentation and affecting the glazing effect on the insulator blank. For example, patent CN218647708U discloses a glazing device for insulator production, including a glazing chamber and an L-shaped support plate mounted on top of it, as well as a glazing mechanism. The glazing mechanism includes a telescopic rod fixed to the bottom of the L-shaped support plate, and the telescopic part of the telescopic rod can move up and down. A small gear is rotatably mounted on the bottom of the telescopic rod, and a fixing mechanism for fixing the insulator is provided at the bottom of the small gear. Through the cooperation between the structures, the insulator can automatically move up and down for glazing. Through the arrangement of the large and small gears, after the insulator leaves the glazing chamber, the large and small gears mesh, and the large gear drives the small gear to rotate, removing residual glaze from the surface of the insulator. Through the fan, after the residual glaze is removed, the insulator is quickly dried and shaped, resulting in a more uniform glaze distribution on the surface of the insulator and preventing glaze buildup. By combining other existing technologies, it was found that the current manufacturing process of UHV insulators generally adopts traditional methods such as manual glazing and semi-automatic glazing, which still have the following technical defects: 1. Poor uniformity of glaze layer: Traditional glazing equipment uses straight-walled glazing tanks of equal width. Due to the large glazing depth of the insulator, there is a significant static pressure difference in the vertical direction of the glaze liquid. The static pressure at the lower end is much greater than that at the upper end, resulting in a thicker glaze layer at the lower end and a thinner glaze layer at the upper end of the insulator. At the same time, the glaze material is prone to sedimentation and stratification in the tank, resulting in uneven glaze layer thickness. 2. The continuous operation capability is weak. The feeding, glazing and unloading processes all require operation and waiting. The batch switching interval is long and the equipment utilization rate is low, which is not conducive to the large-scale, high-efficiency continuous production of UHV insulators. 3. Poor stability: Due to the long length of UHV insulators, the installation and fixing method of transmissions results in poor insulator clamping and fixing effect. During the glazing process, the insulators are prone to shaking and displacement, leading to glaze defects. In addition, the clamping table needs to be immersed in the glazing tank for a long time, and a glaze layer is formed on its surface at the same time, which affects the operation accuracy and service life. Therefore, we propose a glazing device for manufacturing ultra-high voltage insulators to solve the problems mentioned above. Summary of the Invention

[0003] The purpose of this invention is to provide a glazing device for manufacturing ultra-high voltage insulators, so as to solve the problems of poor uniformity of glaze layer, inability to guarantee continuous operation, and poor stability of the current glazing devices mentioned in the background art when glazing insulators.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a glazing device for manufacturing ultra-high voltage insulators, comprising a glazing mechanism, a lifting drive mechanism, a loading mechanism, and a glaze circulation mechanism; The lifting drive mechanism is located on the outside of the glazing mechanism, and the loading mechanism is laterally slidably installed on the inside of the lifting drive mechanism. Two sets of the loading mechanism are provided on the middle and end of the inner side of the lifting drive mechanism. The bottom surface of the loading mechanism is evenly distributed with clamping and positioning mechanisms, which are rotatably installed at the bottom of the loading mechanism. The glaze circulation mechanism is internally connected to the glazing mechanism. The glazing mechanism includes a glazing tank and a baffle. The glazing tank is placed on the ground for use through a side frame integrally set at its bottom. The baffle is installed symmetrically and at an angle inside the glazing tank, forming a glazing space that is wider at the top and narrower at the bottom.

[0005] Furthermore, the baffle has a through hole inside, and the inner diameter of the through hole increases gradually from bottom to top.

[0006] Furthermore, the glaze circulation mechanism includes a circulation pump fixedly installed below the glaze immersion tank and a return pipe extending from the output end of the circulation pump to the top of the glaze immersion tank. The input end of the circulation pump is connected to the bottom end of the glaze immersion space, and the top end of the return pipe is connected to a multi-port discharge pipe installed at the top of the glaze immersion space.

[0007] Furthermore, the lifting drive mechanism includes a lift symmetrically arranged outside the glazing tank and a lifting frame installed inside the lift. The lifting frame is laterally symmetrically rotatably mounted with an adjusting screw that drives the loading mechanism, and the end of the adjusting screw is provided with a drive unit.

[0008] Furthermore, the loading mechanism includes a carrier plate slidably connected to the inner side of the lifting drive mechanism, a connecting cylinder is provided at the end of the carrier plate, and a drive belt is provided on the inner side of the carrier plate to provide rotational drive for the clamping and positioning mechanism.

[0009] Furthermore, the clamping and positioning mechanism includes clamping cylinders evenly arranged below the carrier plate. A fixing ring is connected to the top outer side of the clamping cylinder via a bearing. The fixing ring is fixedly connected to the bottom surface of the carrier plate. A driven gear that meshes with the drive belt is provided at the top of the clamping cylinder. A clamping platform is provided at the bottom inner side of the clamping cylinder.

[0010] Furthermore, the clamping platform is telescopically connected to the inside of the clamping cylinder via a telescopic rod.

[0011] Furthermore, it also includes a bottom limiting mechanism, which includes a retractable connecting structure and a limiting platform. The top end of the connecting structure is connected to the bottom side of the clamping and positioning mechanism, and the limiting platform is fixedly connected to the bottom end of the connecting structure.

[0012] Furthermore, the connecting structure is symmetrically connected to both sides of the clamping and positioning mechanism and the limiting platform. The connecting structure is a connector, which includes an upper support rod whose top end is fixed to the bottom side of the clamping and positioning mechanism and a lower support rod whose bottom end is fixed to the top side of the limiting platform. The bottom end of the upper support rod has mounting holes arranged at equal intervals, and the interior of the lower support rod has a through groove in the shape of a long strip. The upper support rod and the lower support rod are fixedly connected by fixing bolts.

[0013] Furthermore, the limiting platform includes a limiting support, a limiting cylinder, and a buffer platform. The limiting support has a fixing hole on its side for fixing to the connecting structure. The limiting cylinder is rotatably positioned at the center of the limiting support and is coaxially corresponding to the clamping and positioning mechanism. The buffer platform is evenly distributed around the outside of the limiting cylinder. A rubber pad is laid on the upper end of the buffer platform, and the bottom end of the buffer platform is elastically installed to the limiting support by a spring. A support rod is rotatably mounted at the bottom middle part of the limiting support, and a connecting rod is telescopically connected to the top end of the support rod. The connecting rod and the support rod are rotatably connected.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: the glazing device for manufacturing ultra-high voltage insulators can offset the static pressure difference of the glaze liquid, and with the combination of circulating flow and insulator rotation, it can significantly improve the uniformity of the glaze layer, and can simultaneously complete the loading and unloading and glazing, realizing continuous and efficient production, while ensuring that the insulator does not shake or shift during glazing, and ensuring uniform glazing. 1. The glazing tank is formed by inclined baffles to create a gradually changing glazing space that is wider at the top and narrower at the bottom. Combined with the through holes on the baffles with gradually changing diameters from top to bottom, the flow resistance of the glaze liquid is high in the lower section and low in the upper section. This structurally offsets the static pressure difference of the liquid column, avoids the problem of the insulator being thicker at the bottom and thinner at the top, and ensures the uniformity of the glaze layer. 2. A glaze circulation mechanism is set in the glaze tank. When the insulator is glazed, the glaze continuously circulates to ensure the stability of the glaze during the glazing process. When the insulator is raised, lowered and rotated, the flowing glaze can evenly cover the surface of the insulator, improving the integrity of the glaze coating. When the loading mechanism is switching operations, the circulation system runs continuously to maintain the constant state of the glaze and not affect the processing rhythm. 3. The loading mechanism can slide laterally and is set in two sets, which can simultaneously complete the feeding, glazing and unloading processes, shorten the batch switching interval, and have high equipment utilization rate, which is suitable for the needs of large-scale, high-efficiency continuous production of UHV insulators. 4. The clamping and positioning mechanism is evenly arranged on the bottom surface of the loading mechanism. It is used to clamp and rotate the insulator through a unified rotation drive. At the same time, the clamping platform can extend and retract in the clamping and positioning mechanism, which not only facilitates the installation of different insulators, but also reduces the liquid entry area of ​​the clamping and positioning mechanism by lowering it, which helps to reduce the maintenance frequency. 5. The bottom limiting mechanism, which is coaxially set with the clamping and positioning mechanism, can achieve coaxial positioning of long-sized UHV insulators. The bottom flexible support can increase the limiting stability and avoid displacement or breakage during glazing. Attached Figure Description

[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, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Example 1: Please see Figures 1-8 The present invention provides the following technical solution: a glazing device for manufacturing ultra-high voltage insulators, comprising a glazing mechanism, a lifting drive mechanism, a loading mechanism, and a glaze circulation mechanism. The lifting drive mechanism is disposed on the outside of the glazing mechanism, and the loading mechanism is laterally slidably installed on the inside of the lifting drive mechanism. Two sets of loading mechanisms are provided in the middle and end of the inner side of the lifting drive mechanism. Clamping and positioning mechanisms are evenly distributed on the bottom surface of the loading mechanism. The clamping and positioning mechanisms are rotatably installed at the bottom of the loading mechanism. The glaze circulation mechanism is internally connected to the glazing mechanism. The glazing mechanism provides space for glaze to be placed and glazing operation. The lifting drive mechanism drives the carrier mechanism to complete lifting and lateral displacement. The bottom of the carrier mechanism uses a clamping and positioning mechanism to clamp and rotate the insulator. The glaze circulation mechanism is connected and arranged in the glazing mechanism to ensure that the glaze flows continuously, is uniform and has no sedimentation. In specific application scenarios, the core of the glazing mechanism is the glazing tank 1. An integrally formed side frame 11 is installed on the bottom of the outer side of the glazing tank 1, which is used to stably place the device on the ground to ensure that the device does not shake during operation. Two baffles 12 are symmetrically and obliquely installed inside the glazing tank 1. The two baffles 12 enclose the glazing tank 1 to form a gradually changing glazing space that is wider at the top and narrower at the bottom, which is suitable for the glazing requirements of long-sized UHV insulators and counteracts the static pressure difference of the glaze in the vertical direction. At the same time, through holes 121 are opened through the inside of the baffles 12. The inner diameter of the through holes 121 increases gradually from bottom to top, and the density of the through holes 121 also gradually increases from bottom to top. This makes the porosity of the upper section of the baffle 12 greater than that of the lower section, so that the flow resistance of the glaze in the lower section is large and the flow resistance in the upper section is small, which further balances the glaze pressure and prevents the glaze layer from being too thick at the bottom and too thin at the top of the insulator.

[0019] The above technical solution is adopted: by combining the gradient glazing space with the gradient through hole 121, the static pressure difference of the glaze liquid is actively offset from the fluid resistance, which solves the problem of the insulator being thicker at the bottom and thinner at the top in the glaze, and significantly improves the uniformity of the glaze layer thickness.

[0020] In specific application scenarios, the glaze circulation mechanism is integrated on the outside of the glazing mechanism. It includes a circulation pump 13, a return pipe 131, and a multi-port discharge pipe 132. The circulation pump 13 is fixedly installed below the glazing tank 1. Its input end is connected to the bottom of the glazing space to extract the bottom glaze. Its output end is connected to the return pipe 131. The return pipe 131 extends from the outer wall of the glazing tank 1 to the top of the glazing tank 1 and is connected to the multi-port discharge pipe 132. The multi-port discharge pipe 132 is arranged longitudinally along the top of the glazing space. It has multiple discharge ports at equal intervals to evenly return the glaze to the glazing tank 1, so as to realize the continuous circulation of the glaze, prevent the glaze from settling and stratifying, and at the same time allow the flowing glaze to evenly coat the surface of the insulator.

[0021] The above technical solution enables the glaze to circulate dynamically throughout the process, eliminating sedimentation and stratification. The flowing glaze, combined with the rotation of the insulator, forms a uniform glaze layer. Furthermore, the circulation system operates continuously, ensuring consistent glaze condition between batches and not affecting the continuous production rhythm.

[0022] In a specific application scenario, the lifting drive mechanism consists of a lifting machine 2, a lifting frame 21, an adjusting screw 22, and a drive unit 23, which are symmetrically arranged on the outside of the glazing tank 1. The lifting frame 21 is installed inside the lifting machine 2 and can move up and down along the vertical direction of the lifting machine 2. The adjusting screw 22 is symmetrically rotated inside the lifting frame 21. The end of the adjusting screw 22 is connected to the drive unit 23. The drive unit 23 drives the adjusting screw 22 to rotate, thereby driving the lateral sliding displacement of the loading mechanism.

[0023] The above technical solution enables precise lifting and lateral displacement of the loading mechanism. The two loading mechanisms can be independently scheduled, with one set for glazing and the other for loading and unloading, significantly shortening the switching interval and improving equipment utilization.

[0024] In specific application scenarios, the core of the loading mechanism is the carrier plate 3. The carrier plate 3 is connected to the adjusting screw 22 through the connecting cylinder 31 at the end. It completes the lateral movement under the drive of the adjusting screw 22. The inner side of the carrier plate 3 is provided with a drive belt 32 to provide uniform rotation power for the bottom clamping and positioning mechanism. Multiple clamping and positioning mechanisms are evenly distributed on the bottom surface of the carrier plate 3. The core of the clamping and positioning mechanism is the clamping cylinder 4. The top outer side of the clamping cylinder 4 is connected to the fixing ring 41 via the bearing 411. The fixing ring 41 is fixed to the bottom surface of the carrier plate 3 to ensure the stable rotation of the clamping cylinder 4. The top of the clamping cylinder 4 is equipped with a driven gear 42, which meshes with the drive belt 32. When the drive belt 32 is running, it drives all the clamping cylinders 4 to rotate synchronously, so that the clamped insulators rotate evenly during glazing and improve the uniformity of glaze coverage. The bottom inner side of the clamping cylinder 4 is connected to the clamping platform 44 via the telescopic rod 43. The clamping platform 44 adopts an internal expansion clamping structure. When clamping, its claws extend into the center holes at both ends of the insulator. The drive unit drives the claws to expand radially and fit against the inner wall of the center hole of the insulator to achieve fixation. When it is in the limit position, it does not contact the outer circumferential surface of the insulator at all. The clamping platform 44 is telescopic and adjustable to accommodate insulators of different sizes. At the same time, the clamping platform 44 can be lowered during glazing to reduce the liquid immersion area of ​​the clamping cylinder 4 and reduce the impact of glaze adhesion on the loading mechanism.

[0025] The above technical solution is adopted: unified drive ensures that all insulators rotate at the same speed and synchronously, and the internal expansion clamp does not damage the glaze; the telescopic clamping platform 44 can reduce the immersion area of ​​the clamping parts, reduce the frequency of glaze adhesion and maintenance, and extend the service life of the mounting mechanism.

[0026] Example 2: Based on Example 1, please refer to Figures 1-12 The present invention provides another technical solution as follows: a glazing device for manufacturing ultra-high voltage insulators, which further includes a bottom limiting mechanism connected to the lower part of the clamping and positioning mechanism for limiting and supporting the bottom end of the insulator; In specific application scenarios, the bottom limiting mechanism includes a telescopic connecting structure and a limiting platform, which are coaxially corresponding to the clamping cylinder 4. The top of the connecting structure is connected to the bottom side of the clamping and positioning mechanism, and the limiting platform is fixedly connected to the bottom of the connecting structure to provide flexible support for the bottom of the long insulator. The connecting structure is a telescopic rod or other telescopic adjustable rod such as the connector 5. The connector 5 includes an upper support rod 51, a lower support rod 52 and a fixing bolt 53. The top of the upper support rod 51 is fixed to the bottom side of the clamping cylinder 4, and the bottom of the lower support rod 52 is fixed to the top side of the limiting support 6. The bottom of the upper support rod 51 has equidistant mounting holes, and the lower support rod 52 has a long strip-shaped through groove. The fixing bolt 53 passes through the mounting holes and the through groove to adjust the overall length of the connector 5 and adapt to insulators of different lengths. The main body of the limiting platform is a limiting support 6, with a fixing hole 61 on the side for fixing to the lower support rod 52. A limiting cylinder 62 is rotatably installed at the center of the limiting support 6, and a support rod 622 is rotatably installed at the bottom middle of the limiting cylinder 62. The top of the support rod 622 is telescopically connected to a connecting rod 621. The connecting rod 621 is rotatably connected to the limiting cylinder 62 to achieve coaxial positioning. During use, the height of the connecting rod 621 can be adjusted through the telescopic connection between the support rod 622 and the connecting rod 621. The telescopic connection is fixed after telescopic movement to prevent telescopic movement during rotation and glazing. The support rod 622... The rotation of the limiting support 6 and the rotation between the connecting rod 621 and the limiting cylinder 62 ensure the normal rotation of the insulator. The extension and retraction between the support rod 622 and the connecting rod 621 can adapt to the bottom limiting use of insulators with different center hole depths, so that after the insulator is vertically limited, its bottom end will not contact the buffer platform 63. The buffer platforms 63 are evenly distributed around the outer circumference of the limiting cylinder 62. The upper end of the buffer platform 63 is covered with a rubber pad 631, and the bottom end is elastically installed with the limiting support 6 through a spring. When the insulator is tilted during loading or unloading, it can provide buffer support to avoid collision and breakage.

[0027] The above technical solution, through central coaxial limiting and peripheral elastic buffer, ensures the verticality and rotational concentricity of the insulator, effectively suppresses the swaying and displacement of long rod insulators during glazing, prevents glaze defects and rod breakage, and improves processing stability and yield.

[0028] Working principle: When glazing ultra-high voltage insulators, the glaze is pre-injected into the glazing tank 1, and the circulation pump 13 is started. The glaze is drawn from the bottom of the glazing space and flows back to the top of the glazing tank 1 through the return pipe 131 and the multi-port discharge pipe 132, forming a dynamic circulation of the whole tank, eliminating sedimentation in advance and ensuring uniform glaze concentration and fluidity. Start the drive unit 23 of the lifting drive mechanism to drive the adjusting screw 22 to rotate, so that the carrier plate 3 slides precisely laterally along the lifting frame 21 through the connecting cylinder 31, and the first set of loading mechanism stops on the side of the lifting frame 21. At this time, the second set of loading mechanism moves to the top of the glazing tank 1 and the first set of loading mechanism on the side of the lifting frame 21 is loaded. The upper end of the UHV insulator to be processed is clamped by the clamping platform 44 inside the clamping cylinder 4 to complete the internal expansion centering clamping of the top of the insulator without contacting the outer wall of the insulator. The elevator 2 drives the lifting frame 21 to rise, and the carrier plate 3, which has been loaded on the side, is slid to the top of the glazing tank 1 by adjusting the screw 22. Then, the elevator 2 drives the lifting frame 21 to fall, and the insulator clamped below the carrier plate 3 is slowly immersed into the glazing space of the glazing tank 1, which is wider at the top and narrower at the bottom. The clamping platform 44 is driven to fall by the telescopic rod 43, which can reduce the area of ​​the clamping platform 44 entering the glaze liquid. Under the action of the inclined baffle 12 and the gradient enlarged through hole 121, the flow resistance of the glaze liquid is large in the lower section and small in the upper section, which actively counteracts the static pressure difference in the vertical direction and avoids the glaze layer being thick at the lower end and thin at the upper end of the insulator. The inner side of the carrier plate 3 drives the belt 32 to rotate synchronously, and through the driven gear 42, it drives all the clamping cylinders 4 to rotate at the same speed. The insulator rotates at a uniform speed with the clamping cylinders 4, and with the flow of glaze, it achieves 360° uniform coating without dead angles. Meanwhile, the second loading mechanism, which was originally located in the middle, now slides to the other side of the lifting frame 21 to load materials; After the second loading mechanism completes the loading and the first loading mechanism completes the glazing, the elevator 2 drives the lifting frame 21 to rise at a constant speed, lifting the insulator out of the glaze surface. The insulator remains rotating and, under the action of centrifugal force and gravity, throws off excess glaze, achieving uniform glaze drying on the surface. During this drying process, the second loading mechanism is simultaneously inserted into the glaze immersion tank 1 for glazing through sliding adjustment. The equipment operates continuously without interruption. At the bottom of the loading and unloading areas on both sides of the glaze immersion tank 1, receiving troughs can be set to collect the glaze dripping from the glaze. After the first loading mechanism finishes draining, it unloads the material. After unloading, it continues to load the material, and the cycle is repeated. Furthermore, when glazing long insulators, adjust the connecting piece 5 of the bottom limiting mechanism according to the length of the insulator, adjust the relative position of the upper support rod 51 and the lower support rod 52, lock them with the fixing bolt 53, and connect the limiting support 6 directly below the clamping cylinder 4 so that it is coaxially aligned with the insulator; then adjust the extension and retraction of the connecting rod 621 and the support rod 622 so that the limiting cylinder 62 supports the center hole at the bottom of the insulator, achieving coaxial centering. When loading and unloading long insulators, the buffer platform 63 elastically set on the surface of the limiting support 6 can support the insulator when it is tilted, avoiding collision and breakage.
