Description

Technical Field

[0001] The utility model relates to the technical field of porcelain insulator manufacturing, in particular to a porcelain insulator which is glued and fixed by means of glue injection. Background Art

[0002] Insulators are devices installed between conductors at different potentials or between conductors and ground potential components. They can withstand voltage and mechanical stress and are usually made of glass or ceramics. They are called insulators. Hardware needs to be installed at the bottom of the insulator. The hardware can be fixed with glue or bolts.

[0003] When porcelain insulators are fixed by glue, they are usually fixed with a glue consisting of a binder, a filler and an admixture. The binder is usually cement. The setting time of cement is of great significance to the glue process. During the induction period of hydration, the plasticity of the slurry remains unchanged, and then it gradually loses fluidity due to hydration and begins to set, reaching the "initial setting" and then entering the setting stage. The slurry continues to harden until it completely loses its plasticity and has a certain strength, which is the "final setting". After that, the slurry hardens. The time interval from initial setting to final setting is called the setting time.

[0004] It takes about 5.3 hours before the initial setting, about 3.2 hours for the setting time, and the total time is within 9 hours. It takes a long time. In order to avoid the tilt of the porcelain parts during the binding process and reduce the quality of the product, the porcelain parts and accessories need to be positioned before binding to ensure that the size and shape of the insulator meet the requirements after binding. There are three ways of positioning: manual positioning; binding frame positioning; mechanical automatic positioning. The porcelain parts and accessories need to be laid flat and wait for solidification during binding, which leads to a long binding cycle of porcelain insulator products, a large footprint, and difficulty in improving production efficiency.

[0005] Therefore, it is necessary to propose a porcelain insulator that is glued and fixed by glue injection to solve the above problems. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides Figure 1-Figure 4 The porcelain insulator shown is fixed by glue injection, comprising an insulator body 1 and a hardware assembly, wherein the hardware assembly comprises a hardware 7, a clamping block 10 and a clamping slot 11.

[0028] Porcelain insulators are usually fixed with a glue consisting of a binder, filler and admixture, and the binder is usually cement. The setting time of cement is of great significance to the gluing process. During the hydration induction period, the slurry plasticity remains unchanged, and then it gradually loses fluidity due to hydration and begins to set, reaching the "initial setting" and then entering the setting stage. The slurry continues to harden, and when it completely loses plasticity and has a certain strength, it is the "final setting", and then the slurry hardens. The time interval from initial setting to final setting is called the setting time.

[0029] It takes about 5.3 hours before the initial setting, about 3.2 hours for the setting time, and the total time is within 9 hours. It takes a long time. In order to avoid the tilt of the porcelain parts during the binding process and reduce the quality of the product, the porcelain parts and accessories need to be positioned before binding to ensure that the size and shape of the insulator meet the requirements after binding. There are three ways of positioning: manual positioning; binding frame positioning; mechanical automatic positioning. The porcelain parts and accessories need to be laid flat and wait for solidification during binding, which leads to a long binding cycle of porcelain insulator products, a large footprint, and difficulty in improving production efficiency.

[0030] In order to solve the problem that porcelain parts and accessories need to be laid out flat and wait for solidification during gluing, resulting in a long gluing cycle of porcelain insulator products, a large footprint, and difficulty in improving production efficiency, in the utility model, a fixing column 5 is fixedly provided at the bottom of the insulator body 1, and a limiting component is fixedly provided at the outer ring of the fixing column 5. There are four groups of limiting components, and the four groups of limiting components are evenly distributed in a ring shape. The porcelain parts (insulator body 1) and accessories (metal fittings 7) are automatically positioned by the limiting components, thereby replacing manual or mechanical positioning methods.

[0031] Furthermore, the utility model is provided with an auxiliary component, which can quickly fix the porcelain parts and accessories without waiting for the adhesive to solidify. Therefore, after the porcelain parts and accessories are glued and fixed, the porcelain insulators can be stacked up and down and wait for the adhesive to solidify, without the need to lay them flat and wait for solidification. This solves the problem of large floor space occupied by porcelain insulators after gluing, thereby reducing the requirements for the site and improving the production efficiency of porcelain insulators.

[0032] In the utility model: the limiting assembly includes a limiting rod 6, the limiting rod 6 is fixedly connected to the fixing column 5, the clamping block 10 is fixedly arranged at the inner circle of the hardware 7, and four are evenly distributed in a ring shape, the clamping groove 11 is fixedly arranged on the clamping block 10, the limiting rod 6 and the clamping groove 11 match, and the limiting rod 6 is engaged in the clamping groove 11 to complete the positioning of the porcelain parts and accessories.

[0033] The space between the hardware 7 and the fixing column 5 is filled with adhesive to complete the bonding between the porcelain part and the accessories.

[0034] In the utility model, the auxiliary components are arranged in the hardware 7, specifically including a placement box 12 and a bonding block 13. The placement box 12 is fixedly arranged at the bottom of the hardware 7, and the bonding block 13 is fixedly arranged in the middle of the bottom of the fixing column 5. The placement box 12 is filled with quick-drying glue. Before the fixing column 5 is inserted into the hardware 7, a proper amount of quick-drying glue is first placed in the placement box 12, so that after the fixing column 5 is inserted into the hardware 7, the bonding block 13 and the quick-drying glue are squeezed and contacted, so that the placement box 12 and the bonding block 13 are quickly fixed together, thereby realizing the rapid fixation of porcelain parts and accessories.

[0035] It should be noted that the shape of the placement box 12 can be circular, rectangular or other shapes, and this application does not limit this.

[0036] It should also be noted that there are at least two limit rods 6 in each set of limit assemblies, which position the fixed column 5 at different heights through multi-point contact, ensuring that the fixed column 5 can be more aligned and engaged in the hardware 7, and the fixed column 5 is not easy to tilt. When the lower limit rod 6 is in contact with the bottom of the slot 11, the upper limit rod 6 and the slot 11 are at the same height.

[0037] When using the porcelain insulator, the limit rod 6 is inserted into the slot 11. Through the annular arrangement of the four groups of limit rods 6 and the slot 11, it is ensured that when the porcelain insulator is glued, the hardware 7 and the fixing column 5 will not be relatively displaced, thereby ensuring that the hardware 7 and the insulator body 1 are on the same vertical line, improving the quality of product glueing, and solving the problem that when the existing porcelain insulator is glued, it is not possible to ensure that the porcelain part and the hardware 7 are perpendicular to each other, and the porcelain part may tilt during the glueing process, thereby reducing the quality of the product.

[0038] At the same time, after the fixing column 5 is installed in place, the adhesive can bond with multiple limit rods 6, thereby increasing the bonding area between the adhesive and the fixing column 5 and the hardware 7, further increasing the strength of the glue bonding, and avoiding damage to the adhesive caused by external force and vibration during transportation of the insulator after gluing, thereby ensuring the glue bonding strength of the insulator and improving the glue bonding quality of the insulator.

[0039] Considering that in the prior art, binder is usually added to the hardware 7 by pouring, but the amount of binder is difficult to control, and vibration is required during the pouring process so that the binder can be fully filled in the hardware 7, the efficiency is low, and it is easy to have too much or too little binder, resulting in waste.

[0040] Therefore, in the utility model, an annular sealing cover 14 is fixedly provided at the outer ring of the upper end of the fixed column 5. The annular sealing cover 14 is attached to and sealed on the top of the hardware 7. A glue injection pipe 15 is provided on the annular sealing cover 14. When the hardware 7 is filled with adhesive, the adhesive can be injected into the hardware 7 through the glue injection pipe 15. Under the action of the glue injection pressure, the adhesive can be fully filled in the hardware 7, thereby improving the quality and efficiency of the glue assembly without causing waste of adhesive.

[0041] In actual use, an exhaust pipe 16 is provided on the annular sealing cover 14. When glue is injected into the hardware 7, the gas in the hardware 7 is discharged from the exhaust pipe 16. When the hardware 7 is filled with adhesive, the adhesive enters the exhaust pipe 16. At this time, the glue injection can be stopped to avoid waste of adhesive.

[0042] It should be noted that the exhaust duct 16 uses a transparent plastic duct to facilitate observation of whether the adhesive enters the exhaust duct 16 .

[0043] Furthermore, a plurality of equally spaced umbrella skirts 2 are fixedly provided at the outer ring of the insulator body 1, a disc-shaped protrusion 3 is fixedly provided at the top of the insulator body 1, and an arc-shaped groove 4 is fixedly provided on the upper surface of the disc-shaped protrusion 3, and the arc-shaped groove 4 is used for connecting with the wire.

[0044] Furthermore, a mounting rod 8 is fixedly provided at the bottom of the hardware 7, and a limiting ring and a threaded rod are fixedly provided at the bottom of the mounting rod 8 in sequence. A fastening nut 9 is threadedly connected to the outer ring of the threaded rod. Through the mutual cooperation of the fastening nut 9 and the limiting ring, the insulator is conveniently fixedly connected to the external wire rack.

[0045] Furthermore, the surface of the hardware 7 is painted with anti-rust paint, which can extend the service life of the hardware 7.

[0046] Furthermore, when the end of the limiting rod 6 fits against the inner wall of the slot 11, a gap is left between the fixing column 5 and the blocking block 10. With this arrangement, when the adhesive is injected, the adhesive can pass between the two limiting rods 6. After vibration and compaction, the adhesive can be evenly filled between the hardware 7 and the fixing column 5.
