Description

Technical Field

[0001] The invention relates to the technical field of production of insulating porcelain sleeves, in particular to a double-station glazing system for insulating sleeves with continuous glazing production capacity. Background Art

[0002] Insulating bushings are key components for ensuring stable power system operation. They are widely used in power transmission, distribution, and substation equipment, as well as various electrical devices, ensuring insulation safety. Made of electrical ceramic, they offer excellent insulation performance and mechanical strength. They come in a variety of shapes, including cylindrical and shed-shaped. The shed-shaped design increases creepage distance, effectively improving insulation performance and preventing surface flashover in dirty or humid environments.

[0003] Large-sized insulating bushings with an outer diameter exceeding 480mm and a height exceeding 900mm typically possess superior mechanical strength and electrical insulation properties due to their unique size and structure, meeting more stringent operating requirements. However, molding these large-sized insulators is challenging, and the application of glaze to the porcelain surface is particularly critical. Glaze not only provides additional mechanical protection, effectively protecting the porcelain from environmental corrosion, but also significantly improves the insulating bushing's electrical performance, enhancing its withstand voltage capability and reducing surface leakage. Glaze also significantly enhances the porcelain's appearance, increasing its weather and pollution resistance.

[0004] In the prior art, there are three main glazing methods for insulating sleeves: dipping, spraying, and pouring. Among them, dipping means that the part of the porcelain body to be glazed is completely immersed in the glaze slurry, spraying means that the glaze slurry is atomized at high pressure by a spray gun and then sprayed on the surface of the porcelain body, and pouring means that the glaze slurry is evenly sprinkled on the surface of the porcelain body through a nozzle. Although these methods have their own characteristics, they all have certain limitations for the glazing of large-sized insulating sleeves. The dipping method has the advantages of high production efficiency, uniform glaze layer, smooth glaze surface, and rich glaze color, but it is inconvenient to operate for large-sized sleeves and consumes a lot of production resources such as equipment, space, and raw materials; while spraying and pouring glaze have better flexibility, but the production efficiency is relatively low, the uniformity of the glaze layer is difficult to guarantee, and the glaze quality is easily affected by the technical level of the operator and equipment.

[0005] At present, the common operation method for glazing large-sized insulating sleeves is to use a fixing device to fix the porcelain body in an upright position, and while keeping the bottom surface sealed, perform a slurry glazing operation on the inner tube surface of the porcelain body; at the same time, use a spray gun to spray glaze on the outer tube surface of the porcelain body. Although this method solves the glazing problem of large-sized insulating sleeves to a certain extent, this type of glazing system in the existing technology is mostly a single-station structure, which can only glaze one insulating sleeve at a time, resulting in low production efficiency and cannot meet the needs of large-scale production. In addition, before the glazing operation, this type of glazing system must be fixed with the help of special clamping equipment to ensure the sealing of the bottom surface of the porcelain body. The clamping and unloading process is cumbersome and time-consuming, which easily leads to low actual working efficiency of the glazing system. If the glazing mechanism and the glazing spraying mechanism can be fully utilized during the clamping process of the porcelain body of the glazing system, the equipment utilization rate of the glazing system will be significantly improved.

[0006] Based on the above reasons, it is necessary to structurally improve the existing single-station large-size insulating sleeve glazing system so that the idle mechanisms in the glazing system can be fully utilized during the gaps between loading and unloading large-size insulating sleeves, thereby improving production efficiency, meeting continuous production and reducing production costs.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0022] It should be noted that the embodiments of the present invention described in the specification and claims and the above drawings can be implemented in an order other than that shown or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed.

[0023] In addition, the embodiment shown in this detailed description is only one of the embodiments of the present invention, and does not represent all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0024] See also Figure 1 A schematic diagram of a preferred embodiment of a double-station glazing system for an insulating sleeve is shown. In this embodiment, the double-station glazing system includes a main frame 20 and an auxiliary frame 24. The auxiliary frame 24 is arranged beside the main frame 20, and an operating space for a mechanical arm 26 in a glaze gun assembly and an operator's activities is reserved between the auxiliary frame 24 and the main frame 20.

[0025] The main frame 20 and the auxiliary frame 24 are both arranged on the platform structure 17, and an overhead structure cavity is provided at the bottom of the platform structure 17. In addition to being used to set up the electronic control components, the overhead structure cavity is also used to accommodate the driving elements, glaze container and circulation pipeline of the glaze dipping system, as well as the driving elements, glaze container and glaze supply pipeline of the glaze spraying system. Such a design can make rational use of space, avoid the production site from being messy, and is also conducive to the maintenance and inspection of the equipment. In addition, the overhead structure cavity is connected to the main frame 20, the auxiliary frame 24 and the upper component cavity 2 at the top, so as to facilitate the laying and connection of various electrical lines and pipelines. Considering that the upper component cavity 2 is located at a higher position, in order to facilitate management and maintenance, an overhead platform with a guardrail 5 is also provided at the corresponding plane position of the upper component cavity 2 as an inspection platform 6.

[0026] The main frame 20 corresponds to the main workstation, while the auxiliary frame 24 corresponds to the auxiliary workstation. In this embodiment, the main workstation is primarily used for glazing the first porcelain body 12, which has an outer diameter of 560mm and a height of 1050mm, suitable for large-sized insulating sleeves. The auxiliary workstation is primarily used for glazing the second porcelain body 25, which has an outer diameter of 300mm to 500mm and a height of 450mm to 850mm, suitable for small and medium-sized insulating sleeves. The dual-station design allows the system to perform glazing operations on the second porcelain body 25 in parallel during the loading and unloading gap between the first porcelain body 12 and the auxiliary workstation, effectively utilizing time and resources, further improving production efficiency and equipment utilization.

[0027] In order to realize the clamping function of the main working position, a movable clamping tooling for clamping the first porcelain body 12 is provided on the main frame 20, and the movable clamping tooling includes a first sealing base 14 and a first movable top plate 11 arranged relatively to each other. The first sealing base 14 and the first movable top plate 11 respectively have contact surfaces that match the bottom surface and top surface of the first porcelain body 12, and a sealing gasket 23 is also formed on the contact surface of the first sealing base 14 to ensure the sealing performance between the bottom surface of the first porcelain body 12 and the first sealing base 14 in the clamped state.

[0028] The first sealing base 14 is mounted on the extension arm 13, which is fixedly mounted on the extension shaft 8. The shaft 8 has a bearing seat at its top and a shaft drive swivel 16 at its bottom. This swivel 16 is powered by an external stepper motor. The forward and reverse rotation of the stepper motor switches the extension arm 13 between extension and retraction. A horizontal extension surface 15 is formed on one side of the lower portion of the extension arm 13, and the first sealing base 14 is mounted on the surface of this horizontal extension surface 15.

[0029] The first movable top plate 11 is assembled on the first guide rail 34 through the first guide seat 9. The first guide rail 34 is a vertical guide rail formed on the vertical side of the main frame 20. The main frame 20 has a built-in electric push rod as the driving mechanism of the first guide seat 9. Through the action of the electric push rod, the first movable top plate 11 can slide up and down along the first guide rail 34, thereby achieving relative movement with the first sealing base 14, and completing the clamping and fixing of the end face of the first porcelain body 12 during the movement.

[0030] In this embodiment, considering the large size of first ceramic body 12, a guide sleeve 35 is provided on first guide seat 9 to ensure the stability of first movable top plate 11 during its movement. This sleeve 35, in combination with guide rod 18, serves as a guide mechanism for the movement of first movable top plate 11. The cooperation between guide rod 18 and sleeve 35 effectively prevents displacement of first movable top plate 11 during its movement, ensuring the precise clamping of first ceramic body 12.

[0031] In another embodiment, it is also possible to consider providing rubber gaskets on the opposite surfaces of the first movable top plate 11 and the first sealing base 14. The rubber gaskets not only have good sealing performance, but also can effectively prevent the first ceramic body 12 from being damaged during the clamping process.

[0032] To achieve the clamping function of the auxiliary working position, a fixed clamping fixture for clamping the second porcelain body 25 is provided on the auxiliary frame 24. This fixed clamping fixture includes a second sealing base 22 and a second movable top plate 28. The second sealing base 22 and the second movable top plate 28 have similar structural styles to the first sealing base 14 and the first movable top plate 11, respectively, and are designed to match the upper and lower end surfaces of the second porcelain body 25. The second movable top plate 28 is also assembled and slid up and down on the second guide rails 31 on the vertical side of the auxiliary frame 24 via a second guide seat 30, and similarly cooperates with the second sealing base 22 with the sealing gasket 23 to achieve clamping and loosening of the second porcelain body 25. The biggest difference between this fixed clamping fixture and the movable clamping fixture is that the second sealing base 22 remains fixed in position throughout the glazing operation and can only be adjusted in height when needed using the adjustable platform 21. Unlike the movable clamping fixture, the second sealing base 22 can be switched between the working position and the unloading position by extending and retracting the extension arm 13.

[0033] The adjustable platform 21 is disposed on the bottom surface of the platform structure 17 at a position corresponding to the auxiliary frame 24, and the height position is adjusted manually or electrically.

[0034] In this embodiment, the glazing of the inner tubes of the first porcelain body 12 and the second porcelain body 25 is achieved by dipping in glaze. The starting end of the circulation pipeline in the corresponding dipping in glaze system is connected to the dipping glaze container, and a two-way pumping device is used as a driving unit. The end of the circulation pipeline is connected to the first circulation pipeline branch 4 and the second circulation pipeline branch 32 respectively through a tee with a reversing valve. The ends of the first circulation pipeline branch 4 and the second circulation pipeline branch 32 are respectively provided with a main pressure grouting nozzle and an auxiliary pressure grouting nozzle. The main pressure grouting nozzle and the auxiliary pressure grouting nozzle are both two-way nozzles, that is, the functions of grouting into the inner tube of the porcelain and withdrawing the glaze in the inner tube can be respectively realized by the forward and reverse rotation of the two-way pumping device.

[0035] The first circulation branch 4 and the second circulation branch 32 are both made of rigid material. The upper portion of the first circulation branch 4 is mounted on the first branch guide rail 1 via the first branch guide seat 3, while the upper portion of the second circulation branch 32 is mounted on the second branch guide rail 36 via the second branch guide seat 37. The first branch guide rail 1 and the second branch guide rail 36 are arranged on different vertical side walls of the upper component cavity 2 and can be controlled by a stepper motor installed in the upper component cavity 2 to meet the glazing requirements of insulating sleeves of different sizes. During the lifting process, the first circulation pipeline branch 4 and the second circulation pipeline branch 32 extend into the inner tubes of the first porcelain body 12 and the second porcelain body 25 in the clamped state through the preset openings on the first movable top plate 11 and the second movable top plate 28, and continue to probe to the bottom, and then use the main pressure grouting nozzle and the auxiliary pressure grouting nozzle to inject glaze slurry into the inner tubes of the porcelain body respectively. After the glaze slurry fully fills the inner tube, the glaze slurry in the main pressure grouting nozzle and the auxiliary pressure grouting nozzle is withdrawn by controlling the reversal of the two-way pumping device to avoid the glaze slurry dripping and causing pollution to the working environment. During this process, the first movable top plate 11 and the second movable top plate 28 remain stationary to ensure the stability of the grouting operation. After the grouting is completed, the first circulation pipeline branch 4 and the second circulation pipeline branch 32 rise and reset under the guidance of the first branch guide rail 1 and the second branch guide rail 36 respectively, in preparation for the subsequent glaze spraying operation.

[0036] In another embodiment, a technical method can also be selected in which the main pressure grouting nozzle and the auxiliary pressure grouting nozzle are arranged in the middle position of the sealing base, that is, a through hole is opened in the middle position of the bottom surface of the first sealing base 14 and the second sealing base 22 respectively, and the main pressure grouting nozzle and the auxiliary pressure grouting nozzle are fixedly assembled at the position of the through hole, and the upper part corresponds to the inner tube of the porcelain body in the clamping state. With this embodiment, when performing the glaze dipping operation, there is no need to adjust the height position of the first circulation pipeline branch 4 and the second circulation pipeline branch 32. The grouting operation can be started by simply moving the first movable top plate 11 and the second movable top plate 28 down to the corresponding position, and when recovering the glaze slurry, there is no need to adjust the height. It can be completed directly through the withdrawal action of the main pressure grouting nozzle and the auxiliary pressure grouting nozzle. Such a design can further simplify the operating process and improve production efficiency; but it will place higher requirements on the sealing performance of the first sealing base 14 and the second sealing base 22.

[0037] In this embodiment, the glaze on the outer tube surface of the first porcelain body 12 and the second porcelain body 25 is sprayed with glaze, and the specific operating mechanism is a glaze gun assembly arranged between the main frame 20 and the auxiliary frame 24. The glaze gun assembly includes a glaze gun 27, a robotic arm 26, and a glaze gun base 19. The glaze gun base 19 is fixedly mounted on the platform structure 17, and the robotic arm 26 is mounted on the glaze gun base 19 and connected to the glaze gun 27 at the end. The glaze gun base 19 is a liftable base, and the glaze gun 27 is mounted on the glaze gun base 19, and can be programmed to cooperate with the liftable glaze gun base 19 and the robotic arm 26 to perform multi-degree-of-freedom movements, thereby achieving precise glazing of the first porcelain body 12 and the second porcelain body 25 at different positions.

[0038] The nozzle of the glaze gun 27 adopts a fan-shaped wide-angle glaze slurry nozzle. Such a design can make the glaze slurry adhere to the outer tube surface of the porcelain body more evenly, thereby improving the glaze spraying quality.

[0039] In addition, in order to improve the environmental quality during the glaze spraying operation, the main frame 20 and the auxiliary frame 24 are respectively provided with a first curved side block 7 and a second curved side block 33 on the opposite sides of the glaze gun assembly setting position. The corresponding first curved side block 7 and the second curved side block 33 have a cone-shaped cross-section, with the large opening side facing the glaze gun assembly and the small opening back side connected to the negative pressure fan. This design can perform negative pressure suction on the glaze spraying operation area during the glaze gun spraying operation, effectively collect and discharge the glaze mist and dust particles, and the collected glaze slurry can flow into the collection container along the trough body, which is convenient for subsequent processing and reuse, further improving the material utilization rate and environmental protection performance.

[0040] In this embodiment, a rotating shaft support assembly is further provided on the first guide seat 9 and the second guide seat 30, respectively. The rotating shaft support assembly includes a first active rotating seat 10 and a second active rotating seat 29 driven by a motor. The first active rotating seat 10 and the second active rotating seat 29 are respectively assembled and connected to the first movable top plate 11 and the second movable top plate 28, and are assembled with a bearing seat to serve as a first sealing base 14 and a second sealing base 22 as driven rotating seats. After the first porcelain body 12 and the second porcelain body 25 are clamped, the first active rotating seat 10 and the second active rotating seat 29 are driven by the motor to rotate the first porcelain body 12 and the second porcelain body 25 around their own axes. This design enables the glaze gun 27 to be driven to and fro by the mechanical arm 26 during the glaze spraying process, and cooperates with the rotation of the porcelain body to ensure that the glaze slurry can evenly cover the entire outer tube surface of the porcelain body, avoid blind spots in the glaze spraying, and further improve the glaze spraying quality. At the same time, before the glaze spraying operation begins, the operator can set the parameters such as the movement trajectory, spraying speed and glaze slurry flow rate of the glaze gun 27 through the control system. Then the glaze gun assembly can automatically perform the glaze spraying operation according to the preset program to adapt to the glazing requirements of insulating sleeves of different shapes and sizes, so as to cooperate with the glaze gun 27 to perform all-round and dead-angle glazing operations to ensure a uniform glaze layer and a smooth glaze surface.

[0041] During operation, the glazing system of this embodiment first deploys the outward extension arm 13 to the unloading position. The first ceramic body 12 is then hoisted and, after calibrating its position, placed on the surface of the first sealing base 14. The outward extension arm 13 is then retracted to the working position. In the working position, the first movable top plate 11 moves downward to securely hold the first ceramic body 12.

[0042] At this time, the first circulation pipeline branch 4 is guided by the first branch guide rail 1 and descends into the porcelain inner tube of the first porcelain body 12, and glaze slurry is injected into the porcelain inner tube through the main pressure grouting nozzle. After the glaze slurry is fully filled, the main pressure grouting nozzle draws back the glaze slurry to avoid dripping; after the glazing is completed, the first circulation pipeline branch 4 rises and resets. While the glazing operation is in progress, the glaze gun assembly starts working, and the glaze gun 27, driven by the robotic arm 26, evenly sprays glaze on the porcelain outer tube surface of the first porcelain body 12. During the glazing process, the first active turntable 10 drives the first porcelain body 12 to rotate around its own axis to ensure that the glaze slurry is evenly covered until the glazing operation is completed.

[0043] After the glazing operation on the first porcelain body 12 is completed, the outward extension arm 13 is extended again to move the glazed first porcelain body 12 to the unloading position. At this time, the operator can lift it off and replace it with a new first porcelain body 12 to be glazed. During this process, the glazing operation on the second porcelain body 25 in the auxiliary working position is realized through the three-way valve switching and the pre-programmed glaze gun.

[0044] Once the new first porcelain body 12 is placed on the first sealing base 14 and calibrated, the outstretched arms 13 retract, and the first movable top plate 11 moves down to secure it. A new round of dipping and spraying operations then begins. Simultaneously, the already glazed second porcelain body 25 is released from its clamping position, ready for removal by the operator. This parallel operation maximizes time and resources, significantly improving production efficiency.

[0045] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the purpose of these embodiments is only to illustrate the present invention and is not intended to limit the scope of protection of the present invention. In addition, it should also be understood that after reading the technical content of the present invention, those skilled in the art may make various changes, modifications and / or variations to the present invention, and all of these equivalent forms also fall within the scope of protection defined by the claims appended hereto.
