Description

Technical Field

[0001] This invention relates to the technical field of spraying equipment, and specifically to a hoisting method for 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, causing a decrease in the insulation level of the insulators and resulting in 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. Furthermore, insulator spraying is a high-altitude operation, requiring workers to hold spray guns and climb along the insulator string axis while spraying, making the operation difficult and physically demanding. To address this, the applicant has developed an insulator spraying device capable of automatically spraying insulator strings. However, if the installation of this device relies on large lifting equipment (such as a truck crane), it presents problems of high cost and operational risks. If the device is carried to the work location manually, the high-altitude operation is difficult and physically demanding. Therefore, a new lifting solution is urgently needed. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a hoisting method for insulator spraying equipment, which solves the problems of high cost and high operation risk when using hoisting equipment, and the problems of high operation difficulty and high work intensity when using manual climbing and carrying.

[0005] The technical solution to achieve the above objectives is:

[0006] This invention provides a hoisting method for an insulator spraying equipment, comprising the following steps:

[0007] When the insulator spraying equipment is in a horizontal working state, first winches are set on both sides of the insulator spraying equipment, and the first rope wound on the first winch is released.

[0008] Using a drone, the end of the first rope is hooked onto a horizontally arranged insulator string or other nearby structure. Then, the first winch is started to retrieve the first rope to lift the insulator spraying equipment horizontally upward. When the insulator spraying equipment approaches the horizontally arranged insulator string, the insulator spraying equipment is clamped onto the horizontally arranged insulator string, thereby completing the hoisting of the horizontally arranged insulator spraying equipment in working condition.

[0009] When the insulator spraying equipment is in a vertical working state, an auxiliary installation mechanism is provided, and a second winch is provided on the auxiliary installation mechanism.

[0010] The auxiliary installation mechanism is transported to the upper part of the vertically arranged insulator string using a drone, and then clamped onto the pins at the upper part of the vertically arranged insulator string.

[0011] Start the second winch to release the second rope wound on it, and lower the second rope so that the end of the second rope is at the ground;

[0012] The insulator spraying equipment is set vertically, and at least one pair of gears with adjustable spacing and rotatable adjustment and a fifth drive motor driven by the gears are set on the insulator spraying equipment. The spacing of the at least one pair of gears is adjusted so that the at least one pair of gears clamps the second rope and the gears mesh with the teeth set on the second rope.

[0013] The fifth drive motor is started to drive the gear to rotate, so that the gear moves upward along the second rope. When the insulator spraying equipment approaches the vertically arranged insulator string, the operation of the fifth drive motor is stopped, and the insulator spraying equipment is clamped on the vertically arranged insulator string, thereby completing the hoisting of the vertically arranged insulator spraying equipment in working state.

[0014] The hoisting method of this invention enables the insulator spraying equipment to be hoisted onto the insulator strings to be sprayed without the need for manual tower climbing or large hoisting equipment. Regardless of whether the insulator strings are horizontally or vertically positioned, the insulator spraying equipment can be safely hoisted, allowing for automated spraying operations. This hoisting method solves the problems of high cost and high operational risk associated with existing methods using large hoisting equipment, and also addresses the difficulties and high labor intensity associated with manual climbing and carrying methods.

[0015] A further improvement of the hoisting method of the insulator spraying equipment of the present invention is that, after the hoisting of the insulator spraying equipment which is in a vertical working state is completed, a drone is used to remove the auxiliary installation mechanism from the vertically arranged insulator string.

[0016] A further improvement of the hoisting method of the insulator spraying equipment of the present invention is that, after the insulator spraying equipment is clamped on the insulator string that is arranged vertically, the spacing of the gears is adjusted to allow the gears to loosen their clamping on the second rope.

[0017] Start the second winch to retrieve the second rope.

[0018] A further improvement of the hoisting method of the insulator spraying equipment of the present invention is that, after the hoisting of the insulator spraying equipment which is in a horizontal working state is completed, a drone is used to remove the attachment end of the first rope on the first winch from the cable.

[0019] Start the first winch to retrieve the first rope.

[0020] A further improvement of the hoisting method of the insulator spraying equipment of the present invention is that, after the insulator spraying equipment, which is in a horizontal working state, completes the spraying operation, the first winch is started to release the first rope.

[0021] Using a drone, the end of the first rope is hooked onto the cable above the horizontally arranged insulator string. Then, the first winch is started to release the first rope to lower the insulator spraying equipment horizontally downwards. When the insulator spraying equipment is lowered to the ground, the first winch is turned off.

[0022] The first rope's attachment end is removed from the cable using a drone;

[0023] Start the first winch to retrieve the first rope.

[0024] A further improvement of the hoisting method of the insulator spraying equipment of the present invention is that, after the insulator spraying equipment, which is in a vertical position in the working state, completes the spraying operation, a drone is used to transport the auxiliary installation mechanism to the upper part of the vertically arranged insulator string, and the auxiliary installation mechanism is clamped at the upper part of the vertically arranged insulator string.

[0025] Start the second winch to release the second rope wound on it, and lower the second rope so that the end of the second rope is at the ground;

[0026] Adjust the spacing of the gears on the insulator spraying equipment so that the gears clamp the second rope, and the gears mesh with the teeth on the second rope;

[0027] The fifth drive motor is started to drive the gear to rotate, so that the gear moves downward along the second rope. When the insulator spraying equipment moves to the ground, the operation of the fifth drive motor is stopped.

[0028] Increase the gear spacing to release the clamp on the second rope, and start the second winch to retrieve the second rope;

[0029] The auxiliary installation mechanism was removed from the vertically arranged insulator string using a drone.

[0030] A further improvement to the hoisting method of the insulator spraying equipment of the present invention is that it further includes:

[0031] Install a distance sensor on the fixture of the insulator spraying equipment;

[0032] The distance sensor is used to detect the distance between itself and the insulator string;

[0033] The distance detected by the distance sensor is used to determine whether the insulator spraying equipment is close to the corresponding insulator string. Attached Figure Description

[0049] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0050] See Figure 1 This invention provides a method for hoisting insulator spraying equipment, used to transport the equipment to a high-altitude construction location, solving the problems associated with large hoisting equipment and manual climbing for carrying. The hoisting method of this invention has advantages such as simplicity, convenience, operational safety, and low cost. The hoisting method for the insulator spraying equipment of this invention is described below with reference to the accompanying drawings.

[0051] See Figure 1 This document illustrates a flowchart showing the horizontal working state of the insulator spraying equipment in the hoisting method of the insulator spraying equipment of the present invention. The following is in conjunction with... Figure 1 The hoisting method of the insulator spraying equipment of the present invention is described.

[0052] like Figure 1 As shown, when the insulator spraying equipment is in a horizontal working state, the hoisting method of the present invention includes the following steps:

[0053] Execute step S11, set up a first winch on each side of the insulator spraying equipment, and release the first rope wound on the first winch; then execute step S12;

[0054] In step S12, the drone is used to hook the end of the first rope onto the horizontally arranged insulator string or other nearby structures. Then, the first winch is started to retrieve the first rope to lift the insulator spraying equipment horizontally upward. When the insulator spraying equipment approaches the horizontally arranged insulator string, the insulator spraying equipment uses its own clamps to hold onto the horizontally arranged insulator string, thereby completing the hoisting of the horizontally arranged insulator spraying equipment in working condition.

[0055] Preferably, if a cable is installed above the horizontally arranged insulator string, a drone can be used to hook the end of the first rope onto the cable above the horizontally arranged insulator string; if no cable is installed above the horizontally arranged insulator string, the end of the first rope of the first winch on one side can be hooked onto the horizontally arranged insulator string, and the end of the first rope of the first winch on the other side can be hooked onto the cable connected to the horizontally arranged insulator string.

[0056] like Figure 2 As shown, the first winch 262 is located on the outer side of the first support 211 and the second support 212 of the insulator spraying equipment, combined with... Figure 7 As shown, a first rope 263 is wound around the first winch 262, and a hook 264 is provided at the end of the first rope 263. Thus, the first winch 262 starts to release the first rope 263, and then a drone carries the hook 264 to the vicinity of the corresponding insulator string 10. The hook 264 is hooked onto the cable above the horizontally arranged insulator string 10. One first winch 262 is set on each side of the insulator spraying equipment to ensure the stability of the insulator spraying equipment during hoisting. After the drone hooks the hook 264 at the end of the first rope 263, the first winch 262 starts to retrieve the first rope 263. As the first rope 263 is retrieved, the insulator spraying equipment is pulled upwards. When the insulator spraying equipment approaches the horizontally arranged insulator string 10, the first winch 262 stops operating, and then the clamps on the insulator spraying equipment clamp onto the insulator string 10, thus completing the hoisting of the horizontally arranged insulator spraying equipment.

[0057] Furthermore, after the insulator spraying equipment, which is in a horizontal working position, is hoisted, a drone is used to remove the attachment end (i.e., hook 264) of the first rope 263 on the first winch 262 from the cable; then the first winch 262 is started to retrieve the first rope 263. The first winch 262 is located on the side of the insulator spraying equipment and will not affect the spraying operation of the insulator spraying equipment.

[0058] Furthermore, such as Figure 4As shown, when the insulator spraying equipment is in a vertical working state, the hoisting method of the present invention includes the following steps: performing step S21, providing an auxiliary installation mechanism, on which a second winch is provided; then performing step S22;

[0059] Execute step S22, using a drone to transport the auxiliary installation mechanism to the upper part of the vertically arranged insulator string, and clamp the auxiliary installation mechanism onto the pins at the upper part of the vertically arranged insulator string; then execute step S23.

[0060] Execute step S23, start the second winch to release the second rope wound on it, and lower the second rope so that the end of the second rope is at the ground; then execute step S24;

[0061] Execute step S24, set the insulator spraying equipment vertically, and set at least one pair of gears with adjustable spacing and rotatable adjustment and a fifth drive motor connected to the gear drive on the insulator spraying equipment, adjust the spacing of at least one pair of gears so that at least one pair of gears clamp the second rope, and make the gears mesh with the teeth set on the second rope; then execute step S25.

[0062] In step S25, the fifth drive motor is started to drive the gear to rotate, so that the gear moves upward along the second rope. When the insulator spraying equipment approaches the vertically arranged insulator string, the operation of the fifth drive motor is stopped, and the insulator spraying equipment is clamped on the vertically arranged insulator string, thereby completing the hoisting of the vertically arranged insulator spraying equipment in working state.

[0063] like Figure 5 and Figure 6 As shown, the auxiliary installation mechanism 28 includes a telescopically adjustable telescopic member 281, a rotatable rotating seat 282 located at the end of the telescopic member 281, a pair of clamping members 283 located on the rotating seat 282 with adjustable clamping distance, and a second winch 284 located at the end of the telescopic member 281 away from the rotating seat 282. A second rope 285 is wound around the second winch 284. Figure 7 and Figure 15As shown, the bottom of the first support 211 and the second support 212 are 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 second 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 which is vertical in the working state, the auxiliary installation mechanism 28 is transported by a drone to the vertically set insulator string 10 for clamping. Then, the second winch 284 is started to release the second rope 285. When the end of the second rope 285 is lowered to the ground, the second winch 284 is turned off. Next, the gear 266 is engaged with the teeth on the rope 285, and the spacing of the slide block 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. The gear 266 moves upward together with the insulator spraying equipment. When it moves to the vicinity of the vertically set insulator string 10, the clamps on the first support 211 and the second support 212 can clamp onto the insulator string, thus completing the hoisting of the insulator spraying equipment in a vertical working state.

[0064] 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 meshes with the second rope 285, the baffles are located on both sides of the second rope 285, which can limit the second rope and prevent the second rope from moving outward and causing the insulator spraying equipment to fall off.

[0065] Furthermore, such as Figure 5 As shown, after the insulator spraying equipment is clamped onto the vertically arranged insulator string 10, the spacing of the gear 266 is adjusted to allow the gear 266 to release the clamp on the second rope 285; then the second winch 284 is started to retrieve the second rope 285.

[0066] Furthermore, after the insulator spraying equipment, which is in a vertical working state, is hoisted, a drone is used to remove the auxiliary installation mechanism 28 from the vertically positioned insulator string 10 and transport it to the ground.

[0067] In one specific embodiment of the present invention, the method further includes: installing a distance sensor on the fixture of the insulator spraying equipment; using the distance sensor to detect the distance between the insulator and the insulator string; and determining whether the insulator spraying equipment is close to the corresponding insulator string based on the distance detected by the distance sensor.

[0068] Preferably, the distance between the distance sensor and the clamping surface of the fixture is a fixed value. When the distance sensor detects that its distance from the corresponding insulator string is consistent with the fixed value, it indicates that the insulator spraying equipment has been hoisted into place and the fixture can clamp the corresponding insulator string.

[0069] In one specific embodiment of the present invention, such as Figure 2 and Figure 7 As shown, after the insulator spraying equipment, which is in a horizontal working state, completes the spraying operation, the first winch 262 is started to release the first rope 263. At this time, the first rope 263 does not need to be fully released, but only a certain distance is released so that the hook 264 at the end of the first rope 263 can be hooked on the corresponding cable.

[0070] Then, using a drone, the hook 264 at the end of the first rope 263 is hooked onto the cable above the horizontally positioned insulator string 10. The clamps on the insulator spraying equipment are released from the insulator string. Then, the first winch 262 is started to release the first rope 263 to lower the insulator spraying equipment horizontally downwards. When the insulator spraying equipment is lowered to the ground, the first winch 262 is turned off.

[0071] The first rope 263 is removed from the cable by using a drone; the first winch 262 is started to retrieve the first rope 263.

[0072] In one specific embodiment of the present invention, such as Figure 5 , Figure 6 and Figure 15 As shown, after the insulator spraying equipment, which is in a vertical position, completes the spraying operation, the insulator spraying equipment is controlled to move to the lower part of the insulator string to make room for the installation of the auxiliary installation mechanism 28. The auxiliary installation mechanism 28 is then transported to the upper part of the vertically arranged insulator string 10 by a drone, and the auxiliary installation mechanism 28 is clamped at the upper part of the vertically arranged insulator string 10.

[0073] Start the second winch 284 to release the second rope 285 wound on it, and lower the second rope 285 so that the end of the second rope 285 is at the ground;

[0074] Adjust the spacing of gears 266 on the insulator spraying equipment so that gears 266 clamp the second rope 285 and the gears 266 mesh with the teeth on the second rope 285;

[0075] The fifth drive motor 267 is started to drive the gear 266 to rotate, so that the gear 266 moves downward along the second rope 285. When the insulator spraying equipment moves to the ground, the operation of the fifth drive motor 267 is stopped.

[0076] Increase the spacing of gear 266 to release the clamp on the second rope 285, and start the second winch 284 to retrieve the second rope 285;

[0077] A drone was used to remove the auxiliary installation mechanism 28 from the vertically arranged insulator string 10 and place it on the ground.

[0078] The structure of the insulator spraying equipment to which the hoisting method of the insulator spraying equipment of the present invention applies is described below.

[0079] like Figure 7 and Figure 8 As shown, the insulator spraying equipment 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 provided on the first support 211 and the second support 212; the mounting plate 222 is rotatably provided 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 clamped onto the leads of the insulator string to be coated by adjusting the spacing. A rotation adjustment mechanism 23 is connected to the clamps 223, and this mechanism 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 14 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.

[0080] 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.

[0081] The lifting adjustment component 221 can be a vertical cylinder or a push rod motor.

[0082] like Figure 12 As shown, a rotary cylinder 226 is provided on the top of the lifting adjustment component 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.

[0083] A pair of clamps 223 are provided on the top of the mounting plate 222. These clamps 223 can be connected by a bidirectional telescopic cylinder to adjust the distance between them. A clamping plate 2231 is connected to each clamp 223. The opposite side of the clamping plate 2231 has an arc-shaped concave surface that matches the pins on the insulator string. A distance sensor is mounted on the bidirectional telescopic cylinder that connects the clamps 223.

[0084] like Figures 11 to 13 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.

[0085] 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.

[0086] 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.

[0087] Furthermore, combining Figure 8As 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. 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.

[0088] Furthermore, such as Figure 13 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.

[0089] 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.

[0090] 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.

[0091] In one specific embodiment of the present invention, such as Figure 12 and Figure 13As 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.

[0092] 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. There are two rotary adjustment members 252, located at both ends of the bidirectional telescopic cylinder. The rotary adjustment members 252 can be rotated, which can rotate the horizontal telescopic adjustment member 253. 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.

[0093] 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.

[0094] Furthermore, such as Figure 13 and Figure 14 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.

[0095] 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.

[0096] 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.

[0097] In one specific embodiment of the present invention, such as Figure 7 , Figure 9 and Figure 10 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.

[0098] 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.

[0099] Furthermore, combined Figure 3As 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.

[0100] Furthermore, such as Figure 9 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 11 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 7 and Figure 8 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.

[0101] Furthermore, such as Figure 11 As 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.

[0102] Furthermore, such as Figure 9 and Figure 10 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 7 and Figure 8 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.

[0103] 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 to avoid the insulator. The first pusher 213 and the second pusher 214 extend, and the second support 212 is extended. Moving forward, the lifting adjustment member 221 extends again, and the clamp 223 on the second support 212 can clamp at the position of a new pin. Then, the clamp 223 on the first support 211 is released, and 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. By repeating this process, the spraying of the insulator string can be completed.

[0104] 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.

[0105] like Figure 2 , Figure 3 and Figure 5 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.

[0106] When spraying insulator strings arranged horizontally, a drone can be used to attach the hook 264 at the end of the first rope 263 on the first winch 262 to the corresponding cable. Then, the first winch 262 is started to retrieve the first rope 263, thus lifting the insulator spraying equipment horizontally to below the insulator strings 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 strings 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 simultaneously.

[0107] 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.

[0108] 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.

[0109] When spraying paint on the vertically arranged 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 a drone. Then, the second 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 second rope 285. The spacing of the slide block 265 is adjusted so that the gears 266 on both sides clamp the second 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 arranged 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 by 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.

Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
