Abstract
Description
Technical Field
[0001] This invention relates to the technical field of spraying equipment, and specifically to an insulator spraying equipment. Background Technology
[0002] Insulator strings on overhead lines are exposed to rain, sunlight, sea breeze, and sandstorms. The dirt on their surfaces can easily form a conductive film in humid conditions, which reduces the insulation level of the insulators and causes strong discharge phenomena under the action of electricity. Spraying PRTV coating (full name: Persistent In-situ Molding Anti-flashover Composite Coating for External Insulation of Power Equipment) can effectively prevent the formation of a water film on the surface of the insulators, reduce the occurrence of flashover problems, and ensure the stable operation of the power grid.
[0003] Existing paint spraying methods are all manual, which is prone to problems such as defects, drips, and inconsistent coating thickness. In addition, insulator spraying is a high-altitude operation, requiring workers to hold spray guns and climb along the axis of the insulator string while spraying, which is difficult and physically demanding. Therefore, there is an urgent need to provide a new approach solution. Summary of the Invention

[0057] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0058] See Figure 1 This invention provides an insulator spraying device for automatically spraying insulator strings at height. The device uses adjustable-spacing clamps to hold the insulator strings, making it suitable for spraying insulator strings of different diameters. The spraying device can achieve uniform spraying of the internal grooves and external surfaces of the insulator strings, ensuring spraying quality. The structure of the insulator spraying device of this invention will be described below with reference to the accompanying drawings.
[0059] See Figure 1 This diagram shows a structural schematic of the insulator spraying equipment of the present invention. The following is in conjunction with... Figure 1 The structure of the insulator spraying equipment of the present invention will be described.
[0060] like Figure 1 As shown, the insulator spraying equipment of the present invention includes a first support 211, a second support 212, a lifting adjustment component 221, a mounting plate 222, a clamp 223, a rotation adjustment component 23, and a spraying mechanism 24. The first support 211 and the second support 212 are arranged opposite to each other, and the distance between the first support 211 and the second support 212 is adjustable. The lifting adjustment component 221 is disposed on the first support 211 and the second support 212. The mounting plate 222 is rotatably disposed on the top of the lifting adjustment component 221. The clamps 223 are arranged in pairs, with an adjustable spacing between them on the mounting plate 222. The clamps 223 can be adjusted to hold the leads of the insulator string to be coated. A rotation adjustment mechanism 23 is connected to the clamps 223 and can rotate around the clamps 223 in an arc-shaped path. A spraying mechanism 24 is mounted on the rotation adjustment mechanism 23 in an adjustable position. Each rotation adjustment mechanism 23 has at least one set of spraying mechanisms 24. Figure 9 As shown, the spraying mechanism 24 is equipped with multiple rotatable and adjustable nozzles 241. The nozzles 241 can be connected to high-pressure gas or paint to perform cleaning or spraying operations on the insulators.
[0061] A clamp 223 is equipped with a rotation adjustment mechanism 23. A pair of clamps 223 hold the pins of the insulator string to be coated, located between two insulators. The rotation adjustment mechanism 23 on the clamp 223 can rotate and adjust along an arc-shaped path, so that the rotation adjustment range of the two rotation adjustment mechanisms 23 can be connected to form a circle. Combined with the position adjustment function of the spraying mechanism 24, it is possible to achieve spraying of all positions of the insulator. At least one set of spraying mechanisms 24 is provided on the rotation adjustment mechanism 23. This set of spraying mechanisms 24 faces opposite directions and is used to spray the insulators on both sides of the pins. Furthermore, the spraying mechanism 24 can also be connected to high-pressure gas to clean the surface of the insulator, removing impurities. Then, the spraying mechanism 24 is connected to the paint to spray the paint onto the insulator. The switching connection between high-pressure gas and paint can prevent the nozzle from clogging.
[0062] In one specific embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the lifting adjustment component 221 is a vertical cylinder. To ensure the stability of the vertical cylinder's extension and retraction adjustment, multiple guide holes are provided on the vertical cylinder, and a moving rod passes through the guide holes. The end of the moving rod is connected to the end of the cylinder rod of the vertical cylinder. When the cylinder rod extends or retracts, the moving rod can extend out of or into the guide hole along with the cylinder rod. The cooperation between the guide hole and the moving rod plays a guiding and limiting role in the extension and retraction adjustment of the cylinder rod, ensuring the stability of the vertical cylinder's extension and retraction adjustment. In another preferred embodiment, the lifting adjustment frame 221 is a push rod motor.
[0063] A rotary cylinder 226 is provided on the top of the lifting and adjusting frame 221. The rotary cylinder 226 is connected to the mounting plate 222. The rotary cylinder 226 can be rotated and adjusted, thereby rotating and adjusting the mounting plate 222.
[0064] A pair of clamps 223 are provided on the top of the mounting plate 222. The pair of clamps 223 can be connected by a bidirectional telescopic cylinder to adjust the distance between the pair of clamps 223. A clamping plate 2231 is connected to the clamp 223. The opposite side of the clamping plate 2231 has an arc-shaped concave surface that is adapted to the pins on the insulator string.
[0065] A sensor is provided on the bidirectional telescopic cylinder that connects a pair of clamps 223 to detect the distance between it and the pins on the insulator string. The distance between the sensor and the arc-shaped concave surface of the clamping plate 2231 is a fixed value. When the distance detected by the sensor is consistent with the above fixed value, the bidirectional telescopic cylinder can be driven to retract so that the pair of clamping plates 2231 clamp the corresponding pins.
[0066] In one specific embodiment of the present invention, such as Figures 6 to 8 As shown, the rotation adjustment mechanism 23 includes a fixed tooth 231 connected to the clamp 223, a rotating tooth 232 meshing with the fixed tooth 231, a universal joint 233 connecting the fixed tooth 231 and the rotating tooth 232, and a drive member 234 provided on the fixed tooth 231 and driving the rotating tooth 232; the drive member 234 can drive the rotating tooth 232 to rotate and adjust along the fixed tooth 231.
[0067] Preferably, the universal joint 233 is horizontally positioned and is supported and connected between the fixed tooth 231 and the rotating tooth 232. By connecting the fixed tooth 231 and the rotating tooth 232 through the universal joint 233, the rotating tooth 232 can be connected and can be rotated and adjusted around the fixed tooth 231.
[0068] Furthermore, to prevent collisions between the two rotating teeth 232 on the pair of clamps 233 during rotation adjustment, the rotation range of each rotating tooth 232 is limited to a semi-circular range. In a preferred embodiment, the rotation range of the rotating tooth 232 is controlled by a drive member 234. When the drive member 234 drives the rotating tooth 232 to rotate to a certain angle, the drive member 234 then drives the rotating tooth 232 to rotate in the opposite direction. In another preferred embodiment, both the fixed tooth 231 and the rotating tooth 232 are semi-circular teeth, so the rotation adjustment range of the rotating tooth 232 can only be semi-circular. Further, a limit sensor is provided at the end of the semi-circular fixed tooth 231. When the limit sensor detects the rotating tooth 232, it generates a trigger signal to cause the drive member 234 to drive the rotating tooth 232 to rotate in the opposite direction.
[0069] Furthermore, combining Figure 8 As shown, the driving component 234 is a motor, which is mounted on the fixed gear 231. A connecting rod is connected to the motor shaft. One end of the connecting rod is connected to the motor shaft and rotatably connected to the fixed gear 231 via the motor shaft and the motor. The other end is rotatably connected to the rotating gear 232. The motor drives the connecting rod to rotate, which in turn causes the rotating gear 232 to rotate. The connecting rod is located on the side of the rotating gear 232 away from the universal joint 233. Thus, the connecting rod and the universal joint 233 connect the fixed gear 231 and the rotating gear 232 on both sides, providing clamping and limiting for the connection between the fixed gear 231 and the rotating gear 232. Preferably, the motor has a self-locking function, which locks the position after the driving connecting rod rotates to the correct position, and then reverses the rotation drive.
[0070] Furthermore, such as Figures 6 to 8 As shown, a mounting base 235 is provided on the rotating gear 232, and an arc-shaped rack 236 is slidably mounted on the mounting base 235. A drive gear 237 is rotatably connected to the mounting base 235, and the drive gear 237 meshes with the arc-shaped rack 236. A first drive motor 238 is provided on the mounting base 235 and is driven by the drive gear 237. The first drive motor 238 can drive the drive gear 237 to rotate, thereby moving the arc-shaped rack 236. The end of the arc-shaped rack 236 is connected to the spraying mechanism 24. In this way, the position adjustment of the arc-shaped rack 236 combined with the rotation adjustment of the rotating gear 232 realizes the multi-angle adjustment of the spraying mechanism 24, ensuring that the spraying mechanism 24 can spray all positions of the insulator.
[0071] Preferably, the mounting bracket 235 is a rectangular frame structure connected to the side of the rotating gear 232 away from the fixed gear 231. A protruding rib is provided on the inner side of the rectangular frame structure, and a groove is provided on the side of the arc-shaped rack 236. The protruding rib is engaged within the groove, and the interaction between the protruding rib and the groove limits the rotation of the arc-shaped rack 236. The drive gear 237 is located within the rectangular frame structure, and the first drive motor 238 is mounted on the outer side of the rectangular frame structure and is connected to the drive gear 237 for driving.
[0072] Furthermore, a connecting seat 2311 is provided on the side of the fixed tooth 231 away from the rotating tooth 232, and the connecting seat 2311 is fixedly connected to the clamp 223.
[0073] In one specific embodiment of the present invention, such as Figures 6 to 8 As shown, the end of the arc-shaped rack 236 is provided with a bidirectional telescopic adjustment member 251, a rotary adjustment member 252 provided at the end of the bidirectional telescopic adjustment member 251, a horizontal telescopic adjustment member 253 connected to the rotary adjustment member 252, and a mounting base 254 connected to the end of the horizontal telescopic adjustment member 253; the spraying mechanism 24 is rotatably provided on the mounting base 254, and the mounting base 254 is provided with a second drive motor 255 that is drivenly connected to the spraying mechanism 24.
[0074] The bidirectional telescopic adjustment member 251 can be telescopically adjusted in both directions to adjust the distance between the two spraying mechanisms 24, allowing the two spraying mechanisms 24 to approach the corresponding insulators. Preferably, the bidirectional telescopic adjustment member 251 is a bidirectional telescopic cylinder. Two rotary adjustment members 252 are located at both ends of the bidirectional telescopic cylinder. These rotary adjustment members 252 can be rotated, causing the horizontal telescopic adjustment member 253 to rotate as well. The horizontal telescopic adjustment member 253 can be telescopically adjusted to adjust the position of the spraying mechanism 24. The second drive motor 255 can drive the spraying mechanism 24 to rotate, thereby adjusting the nozzle orientation of the spraying mechanism 24. Preferably, the rotary adjustment member 252 is a rotary cylinder, and the horizontal telescopic adjustment member 253 is a horizontal cylinder. Figures 13 to 15 As shown, the clamp 223 is clamped on the insulator string, and the mounting plate 222 connected to the clamp 223 is located at the corresponding edge of the insulator string. Due to the presence of the clamp 223 and the mounting plate 222, the cleaning effect of the insulator string near the clamp 223 and the mounting plate 222 will be affected. However, the bidirectional telescopic adjustment of the bidirectional telescopic adjustment component 251 allows the two spraying mechanisms 24 to extend to both sides of the mounting plate 222, thereby ensuring the cleaning effect of the insulator string near the clamp 223 and the mounting plate 222.
[0075] Furthermore, a spraying mechanism 24 is provided at each end of the arc-shaped rack 236. The spraying mechanism 24 is installed at the end of the arc-shaped rack 236 via a mounting base 254, a horizontal telescopic adjustment component 253, a rotary adjustment component 252, and a bidirectional telescopic adjustment component 251.
[0076] Furthermore, such as Figure 7 and Figure 9 As shown, the spraying mechanism 24 includes a spraying frame 242, an internal gear slewing bearing 243 mounted on the spraying frame 242, a plurality of intermediate wheels 244 meshing with an internal gear ring on the internal gear slewing bearing 243, a sun gear 245 meshing with the plurality of intermediate wheels 244, and a third drive motor 246 mounted on the spraying frame 242 and drivenly connected to the sun gear 245; the intermediate wheels 244 and the sun gear 245 are rotatably connected to the spraying frame 242; the spraying frame 242 is also provided with a spraying pipe 247, which is connected to the intermediate wheels 244 and can rotate and be adjusted together with the intermediate wheels 244, and the end of the spraying pipe 247 forms a nozzle 241.
[0077] Preferably, the spray pipe 247 has multiple spray holes at its nozzle 241. The end of the spray pipe 247 furthest from the nozzle 241 can be connected to an air pump and a paint storage tank. A reversing valve is installed at the connection point between the air pump and the paint storage tank to switch between high-pressure gas and paint. When the spray pipe 247 is connected to the air pump, high-pressure gas is sprayed from the spray holes to clean impurities from the insulator. When the spray pipe 247 is connected to the paint storage tank, paint is sprayed from the spray holes onto the insulator, achieving insulator coating. The switching between high-pressure gas and paint prevents the spray holes from becoming clogged.
[0078] Furthermore, one side of the spray frame 242 is rotatably mounted on the mounting base 254. The second drive motor 255 is driven by the spray frame 242 to drive its rotation adjustment. By driving the spray frame 242 to rotate via the second drive motor 255, the rotation angle of the spray pipe can be adjusted to achieve uniform spraying of the insulator grooves. Preferably, the side of the spray frame 242 is provided with a shaft, which is rotatably connected to the mounting base 254, which is preferably a U-shaped base. The other side of the spray frame 242 is provided with an annular seat, which is connected to the shaft via a support rod. One side of the annular seat is connected to the internal gear slewing bearing 243, and the inner side of the annular seat is connected to a cross-shaped frame. One side of the cross-shaped frame is rotatably connected to the intermediate wheel 244 and the sun wheel 245, and the other side of the cross-shaped frame is provided with a spray pipe 247, which is connected to the rotating shaft of the intermediate wheel 244. Preferably, there are four of each of the rollers 244 and the spray tubes 247. The shaft of the roller is also a hollow shaft, and the end of the hollow shaft away from the spray tube 247 forms a pipe connection port, which can be connected to the air pump and the container for storing paint through a connecting pipe.
[0079] In one specific embodiment of the present invention, such as Figure 1 , Figure 4 and Figure 5 As shown, the first support 211 and the second support 212 are provided with a rotatable and adjustable carrier plate 216 and a fourth drive motor 217 that is drivenly connected to the carrier plate 216; the carrier plate 216 is provided with a telescopic adjustment member 218, and each end of the telescopic adjustment member 218 is provided with a lifting adjustment member 221, and the telescopic adjustment member 218 can adjust the distance between the two lifting adjustment members 221 by telescopic adjustment.
[0080] A pair of clamps 223 are connected to the lifting adjustment component 221. The pins on the insulator string are clamped by the pair of clamps 223. The telescopic adjustment component 218 adjusts the distance between the two lifting adjustment components 221 by telescopic adjustment, so that the two lifting adjustment components 221 can adapt to the spraying of insulators with different spacing.
[0081] Furthermore, combined Figure 14 As shown, when spraying two insulator strings with a small gap, the fourth drive motor 217 can be used to drive the carrier plate 216 to rotate so that the two carrier plates 216 rotate to a parallel state. Then, the telescopic adjustment member 218 adjusts the distance between the two lifting adjustment members 211 so that the two lifting adjustment members 211 can adapt to the gap between the two insulator strings. In this way, the spraying operation of the two insulator strings can be realized at the same time.
[0082] Furthermore, such as Figure 3 As shown, a first arc-shaped guide rail 2111 is provided on the first support 211, and a second arc-shaped guide rail 2121 is provided on the second support 212; combined with Figure 5 As shown, an arc-shaped groove 2161 adapted to the first arc-shaped guide rail 2111 and the second arc-shaped guide rail 2121 is provided on the bottom surface of the carrier plate 216, combined with Figure 1 and Figure 2 As shown, when the carrier plate 216 is mounted on the corresponding first support 211 and second support 212, the arc-shaped slot 2161 on the carrier plate 216 engages with the corresponding first arc-shaped guide rail 2111 and second arc-shaped guide rail 2121. Through the mutual cooperation between the arc-shaped slot 2161 and the first arc-shaped guide rail 2111 and second arc-shaped guide rail 2121, the rotation adjustment of the carrier plate 216 is guided and limited. Preferably, the fourth drive motor 217 is located at the bottom of the first support 211 and second support 212 and is drivenly connected to the corresponding carrier plate 216.
[0083] Furthermore, such as Figure 5As shown, a support block 225 is provided on the carrier plate 216. The end of the telescopic adjustment member 218 is connected to the support block 225. A base plate 224 is provided on the support block 225. A fixing block is provided at the end of the carrier plate 216 away from the support block 225. The fixing block is connected to the telescopic adjustment member 218, and another base plate 224 is connected to the fixing block. The base plate 224 is connected to the corresponding lifting adjustment member 221. When the telescopic adjustment member 218 is telescopically adjusted, it can drive the support block 225 to move and adjust, thereby adjusting the distance between the two lifting adjustment members 221. Preferably, the carrier plate 216 is a telescopic adjustment plate with adjustable length. When the two carrier plates 216 are on the same straight line, the length of the carrier plate 216 is retracted to the minimum state. When the two carrier plates 216 are in a parallel state, the length of the two carrier plates 216 is extended to the maximum state. Specifically, when the telescopic drive member 218 extends outward, it can push the support block 225 forward. The support block 225 moves the end of the carrier plate 216 forward, thereby lengthening the carrier plate 216. Conversely, it can shorten the length of the carrier plate 216. In a preferred embodiment, the carrier plate 216 is a multi-stage sliding plate that is interlocked and can partially overlap, and can slide out or retract step by step to achieve length adjustment.
[0084] Furthermore, such as Figure 3 and Figure 4 As shown, a first pushing member 213 and a second pushing member 214 are connected to the bottom of the first support 211 and the second support 212. These first and second pushing members 213 and 214 are telescopically adjustable. One end of each member is connected to the first support 211, and the other end is connected to the second support 212. The distance between the first and second supports 211 and 212 can be adjusted through telescopic adjustment. Figure 1 and Figure 2 As shown, in conjunction with the clamping and releasing of the clamp 223 on the lifting adjustment component 221 connected to the first support 211 and the second support 212, the insulator spraying equipment can move along the insulator string by itself, thereby realizing the spraying of each insulator on the insulator string one by one, so as to successfully complete the spraying operation of the entire insulator string.
[0085] The insulator spraying equipment moves along the insulator string as follows: When spraying the insulator string, the clamp 223 on the lifting adjustment component 221 clamps onto the pin at one end of the insulator string, defining the first support 211 as being located at the end of the insulator string. After spraying the insulator at the clamped pin, the clamp 223 on the second support 212 is released and the lifting adjustment component 221 is retracted. By retracting the lifting adjustment component 221, the corresponding clamping mechanism 24 is moved away from the insulator, and the first pusher 213 and the second pusher 214 are moved away. Extend the second support 212 forward, then extend the lifting adjustment member 221. The clamp 223 on the second support 212 can clamp at the position of a new pin. Then release the clamp 223 on the first support 211. Then the first push member 213 and the second push member 214 retract, moving the first support 211 forward. The clamp 223 on the first support 211 can also clamp at the position of a new pin. At this time, the insulator at the new pin can be sprayed. Repeat this process to complete the spraying of the insulator string.
[0086] Preferably, the first pusher 213 and the second pusher 214 are cylinders. To improve the stability of the movement adjustment between the first support 211 and the second support 212, guide rods are provided on both sides of the first pusher 213 and the second pusher 214. Guide sleeves are fitted on the guide rods, which are connected to the first support 211. The guide rods are connected to the second support 212 through a connecting block. When the first pusher 213 and the second pusher 214 are extended or retracted, the guide rods move within the guide sleeves. The guide rods and guide sleeves play a guiding and limiting role in the movement adjustment between the first support 211 and the second support 212. To improve the structural stability of the second pusher 214, multiple support plates 215 are connected between the two guide sleeves of the second pusher 214. The cylinder rod of the second pusher 214 passes through the middle of the support plate 215, and the support plate 215 provides support and limits for the extension and retraction adjustment of the cylinder rod.
[0087] In one specific embodiment of the present invention, such as Figure 1 , Figure 10 and Figure 11As shown, the bottom of the first support 211 and the second support 212 are provided with a fixed base 261, and the fixed base 261 is provided with a pair of crossing mechanisms 27; the crossing mechanism 27 includes a height adjusting member 271, a rotatable rotating base 272 disposed on the top of the height adjusting member 271, a lateral adjusting member 273 connected to the rotating base 272, a first adjusting member 274 and a second adjusting member 275 hinged to the end of the lateral adjusting member 273, and a first driving member 27 obliquely connected between the first adjusting member 274 and the lateral adjusting member 273. 6. A second drive member 277 is obliquely connected between the second adjusting member 275 and the lateral adjusting member 273; the lengths of the first adjusting member 274 and the second adjusting member 275 are adjustable, and the first adjusting member 274 and the second adjusting member 275 are arranged perpendicularly to each other; the ends of the first adjusting member 274 and the second adjusting member 275 are provided with rotatable traveling wheels 278 and limit wheels 279; the first drive member 276 and the second drive member 277 are telescopically adjustable to drive the corresponding first adjusting member 274 and the second adjusting member 275 to rotate and adjust.
[0088] Combination Figure 16 As shown, the insulator spraying equipment of the present invention can be attached to the tower via a pair of crossing mechanisms 27. Specifically, after the insulator string on one side of the tower is sprayed by the insulator spraying equipment, the height of the height adjusting member 271 is adjusted so that the first adjusting member 274 and the second adjusting member 275 approach the pole member 13 on the tower. The first driving member 276 and the second driving member 277 retract to pull the first adjusting member 274 and the second adjusting member 275 to rotate in a direction away from each other, so that the first adjusting member 274 and the second adjusting member 275 are in an open state. Then the lateral adjusting member 273 extends forward, allowing the first adjusting member 274 and the second adjusting member 275 to be open. The first adjusting member 274 and the second adjusting member 275 are attached to the corresponding rod 13. Then, the first driving member 276 and the second driving member 277 extend and reset so that the first adjusting member 274 and the second adjusting member 275 are set perpendicular to each other, and the second adjusting member 275 is parallel to the ground. Then, the first adjusting member 274 and the second adjusting member 275 adjust their lengths so that the traveling wheel 278 contacts the corresponding surface of the rod 13, and the limiting wheel 279 is attached to the corresponding surface of the rod 13. This realizes that the insulator spraying equipment can be attached to the corresponding rod through the crossing mechanism 27, and then the connection between the insulator spraying equipment and the insulator string can be released.
[0089] A motor is installed at the traveling wheel 278, which can drive the traveling wheel 278 to rotate. By using the rotation of the traveling wheel 278, the insulator spraying equipment can be carried along the pole 13 of the line tower. When encountering obstacles, the pair of crossing mechanisms 27 can also cross the obstacles, thereby moving from one side of the line tower to the other side to start spraying the insulator string on the other side of the line tower. Specifically, when the front-mounted crossing mechanism 27 encounters an obstacle, the first adjusting member 274 and the second adjusting member 275 extend, allowing the traveling wheel 278 to separate from the corresponding rod surface. Then, the first driving member 276 and the second driving member 277 retract, causing the first adjusting member 274 and the second adjusting member 275 to rotate into an open position. Combined with the retraction of the lateral adjusting member 273, the crossing mechanism 27 detaches from the rod. If the crossing mechanism 27 still cannot avoid the obstacle, the adjusting rotating seat 272 can be rotated to adjust the angle of the crossing mechanism 27 to avoid the obstacle. The motor on the other crossing mechanism 27 starts, driving the traveling wheel 278 to rotate and move forward. After crossing the obstacle, the reverse operation allows the crossing mechanism 27 that has crossed the obstacle to reattach to the rod. Repeating the above steps allows the rear-mounted crossing mechanism 27 to also cross obstacles, thus enabling the two crossing mechanisms 27 to alternately cross obstacles.
[0090] Preferably, the height adjusting member 271 can be a vertical cylinder, which adjusts the height by extension and retraction. In another preferred embodiment, the height adjusting member 271 includes interconnected vertical tubes, and a drive structure consisting of a motor, gears, and a rack is provided inside the vertical tubes to drive the inner vertical tubes to move up and down, thereby realizing the height adjustment of the height adjusting member 271. The rotating base 272 is preferably a rotary cylinder. The lateral adjusting member 273 is preferably a horizontally arranged cylinder. The first adjusting member 274 and the second adjusting member 275 are also preferably cylinders. The first driving member 276 and the second driving member 277 are also preferably cylinders.
[0091] To facilitate the identification of the position of the rod and obstacles by the crossing mechanism 27, sensors are provided in the first adjusting member 274 and the second adjusting member 275 to detect the position of the rod and the position of the obstacle.
[0092] Preferably, the pole 13 on the tower is an angle steel, and the middle part of the traveling wheel 278 is concave, so that it is engaged with the corresponding edge of the angle steel through the concave part, while the limiting wheel 279 is attached to the corresponding surface of the angle steel. In another preferred embodiment, the pole 13 on the tower is a square steel.
[0093] In one specific embodiment of the present invention, such as Figure 1 and Figure 2As described, a first winch 262 is provided on the side of the first support 211 and the second support 212 that is far apart from each other. A rope 263 is wound around the first winch 262, and a hook 264 is provided at the end of the rope 263. Thus, the hook 264 can be hooked onto the cable connected to the insulator string. Then, the first winch 262 starts to wind up and down the rope 263, thereby hoisting the first support 211 and the second support 212 to the position of the cable. Figure 13 As shown, the corresponding clamps 223 on the first support 211 and the second support 212 are then clamped onto the pins 12 of the insulator string 10, completing the connection of the insulator spraying equipment. Then the insulator spraying equipment can blow and spray the insulator string 10.
[0094] Preferably, the hook 264 can be attached to the corresponding cable by manual climbing. In another preferred embodiment, to avoid manual high-altitude work, a drone can be used to bring the hook 264 to the location of the cable and attach the hook 264 to the cable.
[0095] The first winch 262 can hang the insulator spraying equipment on the horizontally arranged insulator string.
[0096] In one specific embodiment of the present invention, such as Figure 12 As shown, the insulator spraying equipment of the present invention further includes an auxiliary installation mechanism 28, which includes a telescopically adjustable telescopic member 281, a rotatable rotating seat 282 disposed at the end of the telescopic member 281, a pair of clamping members 283 disposed on the rotating seat 282 with adjustable clamping distance, and a second winch 284 disposed at the end of the telescopic member 281 away from the rotating seat 282. A rope 285 is wound on the second winch 284.
[0097] Combination Figure 15 As shown, the auxiliary installation mechanism 28 can assist in the installation of the insulator spraying equipment onto the vertically arranged insulator string 10. In use, the telescopic member 281 on the auxiliary installation mechanism 28 is arranged horizontally, and the clamping member 283 of the auxiliary installation mechanism 28 is clamped on the pin 12 at the upper part of the vertically arranged insulator string. Then, the second winch 284 lowers the rope 285 to the ground and connects the end of the rope 285 to the end of the second support 212. Then, the second winch 284 starts to reel in the rope 285, thereby lifting the second support 212 and the first support 211 vertically. When it is lifted to the vicinity of the vertically arranged insulator string 10, the clamps on the first support 211 and the second support 212 can clamp onto the insulator string 10.
[0098] Furthermore, such as Figure 10As shown, the bottom of the first support 211 and the second support 212 is provided with a fixed base 261. The bottom of the fixed base 261 is provided with a pair of adjustable sliding blocks 265. A gear 266 and a fifth drive motor 267 connected to the gear 266 are rotatably mounted on the sliding blocks 265. The rope 285 wound on the second winch 284 is provided with teeth that can mesh with the gear 266. Thus, when hoisting the insulator spraying equipment, after the end of the rope 285 is lowered to the ground, the gear 266 is engaged with the teeth on the rope 285. The spacing of the sliding blocks 265 is adjusted so that the gear 266 clamps the rope 285. Then, the fifth drive motor 267 is started to drive the gear 266 to rotate, so that the gear 266 can move upward along the rope 285. This moves the insulator spraying equipment upward together. When it moves to the vicinity of the vertically arranged insulator string, the clamps on the first support 211 and the second support 212 can clamp onto the insulator string. Preferably, baffles are provided on both sides of the gear 266, with the outer edge of the baffles located outside the outer edge of the gear 266. When the gear 266 and the rope 285 are engaged, the baffles are located on both sides of the rope 285, which can limit the rope and prevent the rope from moving outward and causing the insulator spraying equipment to fall off.
[0099] Preferably, the auxiliary installation mechanism 28 can be transported to the vertically positioned insulator string 10 and clamped using a drone, or it can be installed onto the corresponding insulator string 10 by manual climbing. After the insulator spraying equipment is attached to the corresponding insulator string, the auxiliary installation mechanism 28 can be removed. When removing the auxiliary installation mechanism 28, it can be transported to the ground using a drone, or it can be removed manually by climbing to a high altitude.
[0100] The working process of the insulator spraying equipment of the present invention will be described below.
[0101] like Figures 13 to 15 As shown, the insulator string 10 includes multiple insulators 11 connected together. Two adjacent insulators 11 are connected by pins 12. The insulator string 10 can be arranged horizontally or vertically. The insulator spraying equipment of the present invention is applicable to the above-mentioned insulator string 10 and can complete the high-altitude spraying operation of the insulator string 10.
[0102] When spraying coating on horizontally arranged insulator strings, the hook 264 at the end of the rope 263 on the first winch 262 can be attached to the corresponding cable by manual climbing or by drone. Then, the first winch 262 is started to retract the rope 263, thus lifting the insulator spraying equipment horizontally to below the insulator string to be sprayed. If the distance between the two insulator strings 10 is suitable for the adjustment range of the telescopic adjustment member 218, the fourth drive motor 217 can be started to drive the carrier plate 216 to rotate, so that the two carrier plates 216 are arranged in parallel, and the telescopic adjustment member 218 is telescopically adjusted so that the two lifting adjustment members 221 on the carrier plate 216 can correspond to the pins on the corresponding insulator string 10. Then, after the lifting adjustment member 221 extends into place, it is clamped on the insulator string 10 by the clamp 223, so that the two insulator strings can be sprayed at the same time.
[0103] After the clamp is clamped onto the insulator string 10, the spray pipe 247 is connected to the air pump. High-pressure gas is blown out from the nozzle 241 to clean the adjacent insulators 11. During the cleaning process, the drive component 234 is activated to drive the rotating gear 232 to rotate along the fixed gear 231. The first drive motor 238 is activated to drive the power gear 237 to rotate, thereby driving the arc rack 236 to rotate. The position and posture of the spraying mechanism 24 are adjusted by the bidirectional telescopic adjustment component 251, the rotation adjustment component 252, the horizontal telescopic adjustment component 253, and the second drive motor 255. The third drive motor 246 is activated to drive the sun gear 245 to rotate, which in turn drives the intermediate wheel 244 to rotate. The intermediate wheel 244 rotates the spray pipe 247, so that the high-pressure gas sprayed from the spray pipe 247 can clean the surface of the insulator. Then, the spray pipe 247 is switched to be connected to the paint, and the paint is sprayed from the nozzle 241 onto the insulator 11 to complete the spraying of the insulator 11.
[0104] After the coating of an insulator 11 on an insulator string 10 is completed, the first support 211 and the second support 212 move along the insulator string 10 via the first pusher 213 and the second pusher 214, thus enabling the coating of the next insulator 11, until the entire insulator string 10 is coated. After the coating of the horizontal insulator string 10 is completed, the coating equipment can be removed from the insulator string 10.
[0105] When spraying paint on the vertically set insulator string 10, the auxiliary installation mechanism 28 can be clamped at the pin 12 on the upper part of the insulator string 10 by manual climbing or by drone. Then, the rope 285 on the auxiliary installation mechanism 28 is lowered to the ground, and the gear 266 on the insulator spraying equipment is engaged with the teeth on the rope 285. The spacing of the slide block 265 is adjusted so that the gears 266 on both sides clamp the rope 285. Then, the fifth drive motor 267 is started to drive the gear 266 to rotate. The gear 266 can move upward along the rope 285, moving the insulator spraying equipment upward together. When it moves near the vertically set insulator string, the clamps on the first support 211 and the second support 212 can clamp onto the insulator string 10, completing the attachment of the insulator spraying equipment. The auxiliary installation mechanism 28 can then be removed manually or with the help of a drone. After the insulator spraying equipment is clamped onto the vertically arranged insulator string 10, it can begin to blow and spray the insulator 11. The blowing and spraying process is the same as that for the horizontally arranged insulator string 10, and will not be described again here.
[0106] Combination Figure 16 As shown, after completing the spraying operation on the vertically set insulator string 10, the insulator spraying equipment can be hung on the pole 13 of the tower using the crossing mechanism 27. The insulator spraying equipment can move to the other side of the tower by itself through the crossing mechanism 27 to blow and spray the insulators on the other side of the tower.
