[0051] The present invention provides Figures 1 to 18 A bonding method for hollow porcelain insulators is shown. The bonding method mainly utilizes the simultaneous grinding of the end faces of two hollow porcelain insulators 100 and then bonding the two ground hollow porcelain insulators 100, thereby improving the bonding efficiency of the hollow porcelain insulators 100.

[0052] refer to Figure 1 and Figure 2 As shown in the figure, first, groove surfaces 1001 and convex groove surfaces 1002 are respectively polished at both ends of the hollow porcelain insulator 100. In specific usage scenarios, such as uneven electric field distribution or for mechanical support and safety considerations, it is usually necessary to splice longer insulator strings.

[0053] refer to Figure 3 As shown in , when splicing a longer insulator string, multiple hollow porcelain insulators 100 can be bonded and fixed together according to actual length requirements.

[0054] The specific installation steps are as follows:

[0055] Step 1: First, install the anchor cable on the transmission line and fix one end of the anchor cable;

[0056] Step 2: Insert the hollow porcelain insulator 100 onto the anchor cable from the hollow portion 1003 of the hollow porcelain insulator 100. After inserting a number of hollow porcelain insulators 100 according to the length of the anchor cable, fix the other end of the anchor cable.

[0057] Step 3: Adjacent hollow porcelain insulators 100 are spliced ​​and positioned with each other through the groove surface 1001 and the convex groove surface 1002, and then adhesive glaze is sprayed on the surface of the groove surface 1001 or the convex groove surface 1002. The adhesive glaze bonds and fixes the corresponding groove surface 1001 and the convex groove surface 1002, so that the adjacent hollow porcelain insulators 100 are fixedly connected.

[0058] It should be noted that the surfaces of the groove surface 1001 and the convex groove surface 1002 need to be corroded: the polished end faces are corroded with acid to form a number of evenly distributed pits on the end faces, which are then cleaned to expand the contact area and improve the bonding strength of the hollow porcelain insulator.

[0059] This method can splice porcelain insulator strings of appropriate length according to actual scene requirements and is highly practical.

[0060] It should be noted that the bonding glaze can be chemically cured, and the bonding and fixing time is usually 1.5 to 5 minutes, which is short and meets the needs of high-altitude operations. If the insulator string is bonded on the ground, other bonding glazes can be selected accordingly.

[0061] refer to Figure 4 As shown in , the present invention further discloses a bonding device for hollow porcelain insulators, which includes a chassis 1, a frame 2, a sliding channel 3, an electric push rod 11, a column 27 and a positioning member 28.

[0062] The chassis 1 is provided as a supporting platform at the bottom of the bonding device, the columns 27 are fixedly connected to one side of the upper surface of the chassis 1 , and the columns 27 are distributed vertically; the frame 2 is fixedly installed in the middle of the columns 27 .

[0063] There are two groups of positioning members 28, which are respectively arranged at the upper and lower parts of the frame 2, and both groups of positioning members 28 can be moved along the height direction of the column 27. The positioning members 28 are used to clamp and fix the hollow porcelain insulator 100. The positioning members 28 include structures such as electric splints, which are common existing fixing mechanisms and will not be described in detail here.

[0064] Among them, the interior of the frame 2 is provided with a grinding mechanism for grinding the end face of the hollow porcelain insulator 100. When the two sets of positioning members 28 respectively clamp the two hollow porcelain insulators 100, the grinding mechanism grinds the end faces of the upper and lower hollow porcelain insulators 100 at the same time, replacing the existing method of only grinding the end face of a single hollow porcelain insulator 100, and the grinding efficiency is high.

[0065] It is worth mentioning that when the grinding mechanism of the present invention grinds two hollow porcelain insulators 100 simultaneously, it can also form a convex groove surface 1002 and a groove surface 1001 on the end faces of the two hollow porcelain insulators 100, thereby forming two grinding surfaces of different shapes.

[0066] Furthermore, the two polished surfaces of different shapes can cooperate with each other, and the two hollow porcelain insulators 100 can be bonded and fixed to each other by using the two polished surfaces of different shapes.

[0067] Among them, the electric push rod 11 is arranged on the side of the square frame 2, and the side of the square frame 2 is also provided with a sliding channel 3 for the grinding mechanism to move along a specific trajectory. The electric push rod 11 can push the grinding mechanism to move along the trajectory of the sliding channel 3, thereby grinding the end face of the hollow porcelain insulator 100 into the required shape.

[0068] It should be noted that the shape of the sliding channel 3 can be set according to actual needs, which is convenient for application in the grinding processing of different products and has a wide range of applications. In the present invention, the shape of the sliding channel 3 is a V-shaped track, and sliding channels 3 are provided on both sides of the frame 2.

[0069] refer to Figure 5 As shown in the figure, the present invention also provides a connecting component for connecting the electric push rod 11 and the grinding mechanism. The connecting component can not only be connected between the electric push rod 11 and the grinding mechanism, but also can adapt to the telescopic movement of the electric push rod 11, so that the grinding mechanism can move along the trajectory of the sliding channel 3; at the same time, it does not affect the rotation of the grinding mechanism.

[0070] refer to Figures 5 to 7 、 Figures 10 and 11 and Figure 15 As shown in the figure, the grinding mechanism includes a grinding roller 5 and a limit plate 8. Two limit plates 8 are provided. The limit plates 8 are slidably arranged inside the corresponding sliding channel 3. A first circular groove 29 is opened on the limit plate 8. The first rotating shaft 4 is rotatably arranged on the two first circular grooves 29, and the grinding roller 5 is fixedly connected to the first rotating shaft 4.

[0071] When the limit plate 8 slides inside the sliding channel 3, it will drive the first rotating shaft 4 structure to move synchronously. When the limit plate 8 slides, a power mechanism such as a motor 12 is used to drive the grinding roller 5 to rotate, thereby grinding the upper and lower end faces of the hollow porcelain insulator 100.

[0072] It should be noted that the limiting plates 8 on both sides are both attached to the outer wall of the frame 2 to ensure the stability of the movement of the first rotating shaft 4 and other structures.

[0073] refer to Figure 5 、 Figure 6 、 Figure 12As shown, the connecting assembly cooperates with one of the limit plates 8, and the connecting assembly includes a rotating plate 9 and a sliding sleeve 10. The rotating plate 9 is rotatably connected to the middle part of the limit plate 8, and the rotating plate 9 is slidably connected to the inside of the sliding sleeve 10. The fixed end of the electric push rod 11 is fixedly connected to the outer wall of the frame 2, and the sliding sleeve 10 is fixedly connected to the telescopic end of the electric push rod 11.

[0074] During grinding, the telescopic end of the electric push rod 11 is slowly extended, and the electric push rod 11 drives the sliding sleeve 10 to move synchronously. Since the rotating plate 9 is connected to the corresponding limit plate 8 in rotation, and the rotating plate 9 and the sliding sleeve 10 are in sliding cooperation, the movement of the limit plate 8, the grinding roller 5 and other structures is not affected. Figure 12 When the limit plate 8 is in the left half of the sliding channel 3 and moves to the right, the rotating plate 9 will move downward inside the sliding sleeve 10; when the limit plate 8 moves to the right half of the sliding channel 3 and continues to move to the right, the limit plate 8 will first swing counterclockwise into the right half of the sliding channel 3, and then the rotating plate 9 will move upward inside the sliding sleeve 10; during the movement of the limit plate 8, the grinding roller 5 also moves along the track of the sliding channel 3, thereby achieving the purpose of grinding the hollow porcelain insulator 100 with a fixed track.

[0075] It should be noted that balls are movably embedded in the inner wall of the sleeve 10 or the rotating plate 9 is tilted at a certain angle. The two cooperate so that when the electric push rod 11 pushes the sleeve 10, the rotating plate 9 can slide smoothly in the sleeve 10. The details are not repeated here.

[0076] In summary, based on the setting of the connecting component in the present invention, it is possible to use the horizontally moving electric push rod 11 to push the limit plate 8 to move, and to enable the grinding roller 5 to move along a specific trajectory, thereby grinding the end face of the hollow porcelain insulator 100 to form an end face of a specific shape.

[0077] refer to Figure 4 As shown in FIG, during actual use, the operator uses the positioning member 28 to fix the hollow porcelain insulator 100.

[0078] The hollow porcelain insulator 100 with a convex groove (a convex groove surface 1002 after grinding) is located above the frame 2, with the convex groove facing downward; the hollow porcelain insulator 100 with a concave groove (a concave groove surface 1001 after grinding) is located below the frame 2, with the concave groove facing upward; this facilitates adaptation to the moving trajectory of the grinding roller 5;

[0079] Then, the hollow porcelain insulator 100 located above the square frame 2 is controlled to move downward and fit on the top position of the grinding roller 5, and the hollow porcelain insulator 100 located below the square frame 2 is moved upward and fit on the bottom position of the grinding roller 5. The fit strength between the concave groove or convex groove and the grinding roller 5 can be adjusted by controlling the position of the positioning member 28.

[0080] For further reference, Figure 7 、 Figure 8 、 Figure 13 、 Figure 14 As shown in , considering that dust, debris, etc. generated during the grinding process will adhere to the groove surface 1001 and the convex groove surface 1002, and the groove surface 1001 and the convex groove surface 1002 need to be smooth, in order to improve the cleaning efficiency, the present invention also provides a cleaning component for cleaning dust and debris on the groove surface 1001 and the convex groove surface 1002 during the grinding process, and the cleaning component includes a cleaning roller 7, a second circular groove 30 is opened on the limit plate 8, and the two second circular grooves 30 are rotatably connected to the second rotating shaft 6, and the cleaning roller 7 is fixedly connected to the second rotating shaft 6; when the grinding roller 5 grinds the end face of the hollow porcelain insulator 100, the cleaning roller 7 rotates to clean the end face of the hollow porcelain insulator 100, so as to keep the surface of the groove surface 1001 and the convex groove surface 1002 smooth.

[0081] refer to Figure 6 、 Figure 11 As shown in , to achieve the rotation of the first rotating shaft 4 and the second rotating shaft 6 and other structures, a transmission assembly is provided between the first rotating shaft 4 and the second rotating shaft 6. The transmission assembly includes a pulley 25 and a belt 26. Two pulleys 25 are provided, one of which is fixedly connected to the first rotating shaft 4, and the other pulley 25 is fixedly connected to the second rotating shaft 6. The two pulleys 25 are connected by a transmission belt 26. The motor 12 is fixedly mounted on one of the limit plates 8, and the second rotating shaft 6 is fixedly connected to the drive shaft of the motor 12. When the motor 12 is running, the grinding roller 5 and the cleaning roller 7 can rotate synchronously with the cooperation of the transmission assembly, thereby simultaneously achieving the purpose of grinding and cleaning the end face of the hollow porcelain insulator 100.

[0082] refer to Figure 8 、 Figure 14 As shown in the figure, a receiving groove 13 is provided on the outer wall of the cleaning roller 7, and a plurality of receiving grooves 13 are provided. The plurality of receiving grooves 13 are evenly distributed around the cleaning roller 7. The interior of the receiving groove 13 is fixedly connected to a rotating rod 14, and a support block 15 is rotatably connected to the rotating rod 14. The support block 15 is fixedly connected to the end away from the rotating rod 14 with a cleaning strip 16. The cleaning strip 16 can be made of rubber material, which will not cause wear of the concave grooves and convex grooves. It can also be replaced with a cleaning brush and can be adjusted according to specific usage.

[0083] refer to Figure 8 As shown in , a torsion spring 18 is sleeved on the rotating rod 14 , one end of the torsion spring 18 is fixedly connected to the support block 15 , and the other end of the torsion spring 18 is fixedly connected to the rotating rod 14 .

[0084] Reference Figure 13 、 Figure 14As shown in FIG, the grinding roller 5 and the cleaning roller 7 move to the left, the grinding roller 5 rotates counterclockwise to grind the end surface of the hollow porcelain insulator 100, and the cleaning roller 7 rotates counterclockwise synchronously.

[0085] When one of the cleaning strips 16 contacts the convex groove surface 1002 located at the upper position, the cleaning strip 16 will scrape and clean the debris remaining on the convex groove surface 1002 due to grinding; as the cleaning roller 7 continues to rotate, the cleaning strip 16 and the support block 15 will be squeezed by the convex groove surface 1002 and recovered to the inside of the corresponding receiving groove 13, without affecting the rotation of the cleaning roller 7 and maintaining the push and scraping of the convex groove surface 1002; the cleaning roller 7 continues to rotate, and under the action of the reset elastic force of the torsion spring 18, the cleaning strip 16 and the support block 15 are gradually reset. When the cleaning strip 16 is out of contact with the convex groove surface 1002, the reset elastic force of the torsion spring 18 causes the cleaning strip 16 and the support block 15 to quickly bounce open and produce a shaking effect, so that the debris remaining on the cleaning strip 16 is shaken off, ensuring the subsequent cleaning effect, and at the same time, the cleaning strip 16 at the next position continues to clean the convex groove surface 1002.

[0086] The cleaning roller 7 continues to rotate, and the cleaning strip 16 cleans the debris remaining on the groove surface 1001 (same as the cleaning steps for the convex groove surface 1002).

[0087] In the present invention, by providing structures such as cleaning rollers 7 and cleaning strips 16, debris remaining on the groove surface 1001 and the convex groove surface 1002 due to grinding is scraped and cleaned, and multiple cleaning strips 16 are switched and coordinated to ensure the cleaning effect.

[0088] Reference Figure 14 As shown in , considering that dust easily adheres to and remains inside the storage groove 13, when accumulation occurs, it will affect the use of structures such as the cleaning strip 16 and the support block 15, an elastic strip 17 is fixedly connected to the inner wall of the storage groove 13, and the support block 15 cooperates with the elastic strip 17.

[0089] Specifically, when the cleaning strip 16 and the supporting block 15 are squeezed by the convex groove and retracted into the corresponding storage groove 13, the elastic strip 17 will be squeezed. When the cleaning strip 16 and the supporting block 15 are rotated and reset to the outside of the storage groove 13, the elastic strip 17 is reset synchronously, producing a plucking effect inside the storage groove 13, thereby preventing dust from adhering to and remaining inside the storage groove 13.

[0090] Furthermore, considering the removal of dust and debris during cleaning, a dust removal component is provided, referring to Figure 5 、 Figure 7 、 Figure 9 、 Figure 10As shown in the figure, a slide groove 19 is provided on the inner walls on both sides of the frame 2, and a slide plate 20 is slidably connected to the inside of the slide groove 19. One end of the slide plate 20 located outside the slide groove 19 is fixedly connected to an elastic telescopic rod 21, and the elastic telescopic rod 21 is located below the slide plate 20. A round box 22 is fixedly connected to the bottom of the elastic telescopic rod 21, one of the round boxes 22 is surrounded by the outside of the first rotating shaft 4, and the round box 22 is rotatably connected to the first rotating shaft 4; the other round box 22 is surrounded by the outside of the second rotating shaft 6, and the round box 22 is rotatably connected to the second rotating shaft 6.

[0091] Take the first rotating shaft 4 as an example: when the limit plate 8 drives the first rotating shaft 4 to move from the end of the sliding channel 3 to the middle, it presents a gradually inclined downward movement trajectory. During this process, the elastic telescopic rod 21 will adaptively extend. At the same time, the round box 22 is rotatably connected to the first rotating shaft 4 without affecting the rotation of the first rotating shaft 4; the dust suction and blowing devices can be connected to the two round boxes 22 respectively, blowing air from one end of the grinding mechanism and sucking dust from the other end, thereby removing dust and debris around the grinding mechanism.

[0092] Reference Figure 16 、 Figure 17 As shown, a square box 32 is provided on the side of the square box 2, and the side of the square box 32 is connected to the airbag 31, and one of the airbags 31 on both sides is located at the head end of the square box 2, and the other airbag 31 is located at the tail end of the square box 2. The head end and the tail end of the square box 2 are not limited in the present invention, and the head end can be any end of the square box 2 close to or away from the column 27.

[0093] When the two boxes 32 move to the right, Figure 17 The airbag 31 at the lower end is squeezed and contracted by the corresponding square box 32, and the gas inside it can be discharged into one of the round boxes 22 and act on the surrounding of the grinding mechanism to achieve the purpose of blowing dust; the airbag 31 at the upper end is stretched and expanded by the corresponding square box 32, and can generate suction at the position of the other round box 22 to suck away the dust around the grinding mechanism.

[0094] Reference Figure 16 As shown in the figure, ear plates 23 are fixedly connected to the outer walls of both sides of the square frame 2, and two ear plates 23 are provided on each side. A guide rod 24 is fixedly connected between the corresponding two ear plates 23, and two guide rods 24 are provided, and the two guide rods 24 are correspondingly distributed up and down; the upper and lower ends of the square box 32 are respectively slidably set on the two guide rods 24, and the end of the airbag 31 away from the square box 32 is fixedly connected to the corresponding ear plate 23, and the square box 32 can move back and forth on the guide rod 24; in addition, the guide rods 24 located above and below the airbag 31 can limit the airbag 31 to ensure that the airbag 31 expands or contracts stably.

[0095] In summary, the present invention realizes dust removal by utilizing the residual power during the movement of the grinding mechanism based on the arrangement of the square box 32 and the airbag 31 and other structures.

[0096] Reference Figure 9 As shown, in the specific setting, the bottom end of the square box 32 is connected to the first air duct 33, the first air duct 33 is U-shaped, and the corresponding round box 22 is provided with a through hole for the first air duct 33 to pass through one end away from the square box 32, and a filter box 35 is installed on the first air duct 33.

[0097] Reference Figure 9 As shown, the bottom end of the square box 32 is connected to a second air duct 36, and the second air duct 36 is U-shaped. A through hole is opened on the round box 22 on the same side for the second air duct 36 to pass through one end away from the square box 32. A second one-way valve 37 is installed on the second air duct 36. The second one-way valve 37 allows the gas inside the square box 32 and the airbag 31 to be discharged through the second air duct 36 without flowing in the opposite direction.

[0098] The first air duct 33 and the second air duct 36 are both made of hard materials, such as stainless steel. When the round box 22 moves, the square box 32 will be driven to move synchronously. The round box 22 is provided with through holes that cooperate with the first air duct 33 and the second air duct 36. When the round box 22 moves in a V-shaped trajectory, the first air duct 33 and the second air duct 36 slide adaptively inside the corresponding through holes without affecting the cooperation between them.

[0099] Reference Figure 17 As shown, when the two square boxes 32 move to the right, the air bag 31 at the lower end position in the figure is squeezed and contracted by the corresponding square box 32. With the cooperation of the first one-way valve 34 and the second one-way valve 37, the gas inside it can be discharged from the corresponding second air duct 36, and the round box 22 at the lower end position supplies air to the grinding roller 5 and the cleaning roller 7; while the air bag 31 at the upper end position is stretched and expanded by the corresponding square box 32. With the cooperation of the first one-way valve 34 and the second one-way valve 37, it can be sucked by the first air duct 33 and the round box 22 at the upper end position, thereby forming a cleaning airflow along the axial direction of the grinding roller 5 and the cleaning roller 7. The cooperation of air supply and suction can quickly remove dust, debris, etc. to prevent it from affecting the external environment, and the dust and debris are filtered inside the filter box 35; if the two square boxes 32 move to the left, the wind direction is opposite, and the same effect of cleaning dust and debris is achieved.

[0100] In addition, the cleaning airflow cooperates with the scraping and cleaning of the cleaning strip 16 to achieve efficient cleaning.

[0101] The structures such as the slide groove 19, the slide plate 20 and the elastic telescopic rod 21 are provided so that the round box 22 moves synchronously with the grinding roller 5, the cleaning roller 7 and the like in a V-shaped trajectory, and the cleaning airflow is always located at the grinding roller 5 and the cleaning roller 7 to ensure the suction effect.
