Description

Technical Field

[0001] This invention relates to the technical field of power maintenance equipment, and specifically to a self-propelled machine for coating insulating coatings on live bare conductors. Background Technology

[0002] Overhead power lines generally use bare conductors, but due to the complex external environment, they often encounter severe weather such as thunderstorms and storms, which can easily cause short circuits between power lines, thus greatly affecting power supply. Therefore, it is currently necessary to spray an insulating layer on the surface of the bare conductors to prevent short circuits between power lines.

[0003] Currently, painting is generally done manually, but this method suffers from low efficiency, high operational risks, and inconsistent paint finishes. Therefore, a new 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 self-propelled coating machine for insulating bare conductors, which solves the problems of safety hazards and risks associated with existing bare conductors, as well as the significant safety risks, low efficiency, and poor consistency of coating results caused by manual spraying.

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

[0006] This invention provides a self-propelled coating machine for insulating live bare wires, comprising:

[0007] Support;

[0008] The traveling mechanism supported on the bearing seat is used to clamp the corresponding bare wire and can travel along the corresponding bare wire;

[0009] A cleaning mechanism is mounted on the support base and is located close to the walking mechanism. The cleaning mechanism is used to clean bare wires.

[0010] A spraying mechanism is mounted on the support base. The spraying mechanism is arranged opposite to the cleaning mechanism. The spraying mechanism is used to clamp the bare wire and perform spraying operations on the outer periphery of the bare wire.

[0011] A positioning clamp mounted on the support is used to clamp the corresponding bare wire to position the support.

[0012] An adjustable obstacle-crossing clamp located on the side of the support can clamp the corresponding part of the bare wire and then move the support by telescopic adjustment, so that the corresponding mechanism on the support can cross the obstacle on the bare wire.

[0013] The coating equipment of this invention can clamp onto bare conductors, achieving automatic cleaning of the conductors and effectively removing dust and bird droppings. Then, it sprays a protective coating onto the conductors, effectively addressing safety hazards and corrosion risks associated with bare conductors. Furthermore, the coating equipment has an obstacle-crossing function, using an obstacle-crossing clamp to hold the bare conductor, allowing other mechanisms on the support to sequentially overcome obstacles on the conductor. This solves the problems of low efficiency, high operational risk, and poor coating consistency associated with manual spraying.

[0014] A further improvement of the self-propelled coating machine for insulating live bare wires of the present invention is that the walking mechanism includes a lower walking wheel that can be raised and lowered and is supported on the support seat, a walking bracket that can be rotated and adjusted and is provided on the support seat, an upper walking wheel that can be rotated and is provided on the walking bracket, and a first motor provided on the walking bracket and drivenly connected to the upper walking wheel.

[0015] By rotating and adjusting the walking bracket, the upper walking wheel can be hooked onto the top of the bare conductor.

[0016] The lower traveling wheel is supported at the bottom of the bare conductor by lifting and adjusting, and thus clamps the bare conductor together with the upper traveling wheel;

[0017] The first motor can drive the upper traveling wheel to rotate, thereby enabling it to travel along the bare conductor.

[0018] A further improvement of the self-propelled coating machine for insulating live bare wires of the present invention is that the cleaning mechanism includes a pair of cleaning brackets that are rotatably adjustable and mounted on the support base, a rotating housing that is rotatably mounted on the cleaning brackets, a plurality of bristles on the outer periphery of the rotating housing, and a second motor mounted on the cleaning brackets and drivenly connected to the rotating housing.

[0019] The pair of cleaning brackets are located on both sides of the bare conductor;

[0020] By rotating the cleaning bracket, the rotating housing can be positioned close to the bare wire;

[0021] The second motor can drive the rotating housing to rotate, thereby the brush bristles cleaning the bare wire.

[0022] A further improvement of the self-propelled coating machine for insulating live bare wires is that the rotating housing is provided with a plurality of air jet holes;

[0023] The top of the rotating housing is provided with a slip ring, and an air inlet pipe is connected through the slip ring. One end of the air inlet pipe is connected to the interior of the rotating housing, and the other end is connected to an air compressor placed in the support.

[0024] A further improvement of the self-propelled coating machine for insulating live bare wires of the present invention is that the spraying mechanism includes a pair of spraying brackets that are rotatably adjustable and mounted on the support base, and a snap-fit ​​plate mounted on the spraying brackets and fitted onto the bare wire.

[0025] The pair of spray coating brackets are arranged opposite each other and located on both sides of the bare conductor;

[0026] The snap-fit ​​plate is provided with a snap-fit ​​groove corresponding to the bare wire. The snap-fit ​​plate is also provided with a liquid supply channel communicating with the snap-fit ​​groove. The other end of the liquid supply channel is located on the outside of the snap-fit ​​plate and forms a liquid supply port.

[0027] A further improvement of the self-propelled coating machine for insulating live bare wires of the present invention is that it also includes a positioning mechanism located near the spraying mechanism, the positioning mechanism being used to clamp the bare wire to achieve positioning of the bare wire.

[0028] A further improvement of the self-propelled coating machine for insulating live bare wires of the present invention is that the positioning clamp and the obstacle-crossing clamp have the same structure, both including a connecting seat, a pair of clamping rods rotatably adjustable in the middle and connected to the connecting seat, a connecting plate connected to the end of the clamping rod away from the bare wire, a sliding rod supported and connected to the connecting seat and close to the end of the clamping rod away from the bare wire, a spring sleeved on the sliding rod and connected to the end of the connecting seat and the corresponding clamping rod, and a liftable and adjustable top rod provided on the connecting seat and corresponding to the pair of connecting plates;

[0029] The clamping rod has a clamping head at one end near the bare conductor;

[0030] The spring pulls the end of the corresponding clamping rod so that the clamps on the pair of clamping rods are positioned far apart;

[0031] The top of the push rod is provided with a conical push head. By moving the push rod upward, the push head extends between a pair of connecting discs, thereby causing a pair of clamping rods to rotate around the center, and then the pair of clamping heads move closer to each other to clamp the bare wire.

[0032] A further improvement of the self-propelled coating machine for insulating live bare wires is that it also includes a hanging mechanism on the support base, wherein the hanging mechanism is provided with a retractable and adjustable lifting strap and a hook connected to the end of the lifting strap.

[0033] A further improvement of the self-propelled coating machine for insulating live bare wires of the present invention is that the hanging mechanism further includes a rotatable guide wheel located on the side of the support seat and a telescopically adjustable limiting wheel located inside the support seat;

[0034] The limiting wheel and the guide wheel are located on the same side of the bearing seat, and the side where the guide wheel is located is adjacent to the side where the obstacle-crossing clamp is located;

[0035] The side of the bearing seat has an opening that communicates with the interior, corresponding to the limiting wheel;

[0036] The lifting sling can pass over the top of the guide wheel and then over the bottom of the limiting wheel, and then lift the support seat through the hook, so that the support seat is in a vertical state with the side where the guide wheel is located facing upward.

[0037] A further improvement of the self-propelled coating machine for insulating live bare wires is that the side of the support seat is provided with an inclined guide plate.

[0038] The beneficial effects of the self-propelled coating machine for insulating live bare wires of this invention are as follows:

[0039] The insulating coating machine is equipped with a hanging mechanism that enables automatic hoisting and lowering without the need for hoisting equipment, thus saving operating costs.

[0040] The walking mechanism, cleaning mechanism, and spraying mechanism of the insulating coating machine can be easily attached to bare wires and easily removed from them.

[0041] The bristles on the rotating housing help clean the gaps in the bare wires and the ends of the wire clamps, while the high-pressure air jet helps blow away dust, improving the cleaning effect.

[0042] The lever can change the position of the lifting sling, which can prevent interference with the bare conductor below during lowering. Attached Figure Description

[0058] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0059] See Figure 1This invention provides a self-propelled coating machine for insulating bare conductors, used to automatically clean and spray bare conductors at heights, avoiding manual high-altitude work, ensuring operational safety, and offering high work efficiency. The self-propelled coating machine for insulating bare conductors is described below with reference to the accompanying drawings.

[0060] See Figure 1 This image shows a three-dimensional structural schematic diagram of the self-propelled coating machine for insulating live bare wires in operation. (See attached image.) Figure 2 This diagram shows the structure of the self-propelled coating machine for insulating live bare wires of the present invention, omitting the support base. The following is a related illustration. Figure 1 and Figure 2 The invention describes a self-propelled coating machine for insulating live bare wires.

[0061] like Figure 1 and Figure 2 As shown, the self-propelled coating machine 20 for insulating live bare wires of the present invention includes a support base 21, a walking mechanism 22, a cleaning mechanism 23, a spraying mechanism 24, a positioning clamp 25, and an obstacle-crossing clamp 25a. The walking mechanism 22 is supported on the support base 21 and is used to clamp the corresponding bare wire 11 and can walk along the corresponding bare wire 11. The cleaning mechanism 23 is supported on the support base 21 and is located close to the walking mechanism 22. The cleaning mechanism 23 is used to clean the bare wire 11. The spraying mechanism 24 is supported on the support base 21. The spraying mechanism 24 is arranged opposite to the cleaning mechanism 23. The spraying mechanism 24 is used to clamp the bare conductor 11 and spray the outer periphery of the bare conductor 11. The positioning clamp 25 is supported on the support seat 21. The positioning clamp 25 is used to clamp the corresponding bare conductor 11 to position the support seat 21. The obstacle crossing clamp 25a is telescopically adjustable and is provided on the support seat 21. The obstacle crossing clamp 25a can clamp the corresponding part of the bare conductor 11 and then drive the support seat 21 to move through telescopic adjustment, so that the corresponding mechanism on the support seat 21 can cross the obstacle on the bare conductor 11.

[0062] The working principle of the self-propelled bare conductor insulation coating machine 20 of the present invention is as follows: the walking mechanism 22 clamps the bare conductor 11 and moves along the bare conductor 11, thereby suspending the support seat 21 on the bare conductor 11. Then, the cleaning mechanism 23 is activated to clean the bare conductor 11. After cleaning, the spraying mechanism 24 sprays the bare conductor 11 to protect it. When the insulation coating machine 20 encounters an obstacle, the obstacle-crossing clamp 25a extends and clamps the bare conductor 11. Then, the mechanism that encountered the obstacle opens to avoid the obstacle. Figure 1Taking the state shown as an example, if the front of the cleaning mechanism 23 encounters an obstacle, after the obstacle-crossing clamp 25a clamps the bare wire 11, the cleaning mechanism 23 adjusts in a direction away from the bare wire 11 to avoid the obstacle. Then, while keeping the obstacle-crossing clamp 25a stationary, it retracts and adjusts to move the carrier 21 forward, so that the cleaning mechanism 23 crosses the obstacle. Then, the walking mechanism 22 behind the cleaning mechanism 23 encounters an obstacle. Similarly, it can extend the obstacle-crossing clamp 25a and clamp the bare wire 11. When the clamping state of the walking mechanism 22 is released, the bare wire can be clamped by the positioning clamp 25 and the spraying mechanism 24 to maintain the stability of the carrier 21. By continuously extending and retracting the obstacle-crossing clamp 25a, the carrier 21 can be moved forward, so that the corresponding mechanism on the carrier 21 avoids the obstacle.

[0063] In one specific embodiment of the present invention, such as Figure 1 , Figure 3 and Figure 4 As shown, the walking mechanism 22 includes a lower walking wheel 221 that is adjustable in height and supported on a support base 21, a walking bracket 222 that is adjustable in rotation and is mounted on the support base 21, an upper walking wheel 223 that is rotatably mounted on the walking bracket 222, and a first motor 224 mounted on the walking bracket 222 and drivenly connected to the upper walking wheel 223. By rotating and adjusting the walking bracket 222, the upper walking wheel 223 can be hooked onto the top of the bare conductor 11. The lower walking wheel 221 is supported on the bottom of the bare conductor 11 by adjusting its height, and thus clamps the bare conductor 11 together with the upper walking wheel 223. The first motor 224 can drive the upper walking wheel 223 to rotate, thereby realizing the walking along the bare conductor 11.

[0064] The walking mechanism 22 of the present invention is clamped onto the bare conductor 11 by upper walking wheels 222 and lower walking wheels 221 arranged vertically, which can ensure the stability of the bearing seat 21 hanging on the bare conductor 11. Furthermore, there are two walking mechanisms 22, located at the front and rear of the top surface of the bearing seat 21, respectively, to improve the hanging stability of the bearing seat 21.

[0065] The process of attaching the walking mechanism 22 of the present invention to the bare conductor 11 is as follows: After the support seat 21 is hoisted near the bare conductor 11, the upper walking wheel 223 on the walking support 222 is attached to the upper part of the bare conductor 11 by rotating and adjusting the walking bracket 222. Then, the lower walking wheel 221 is moved upward and adjusted so that the lower walking wheel 221 and the upper walking wheel 222 clamp the bare conductor 11 together. This completes the attachment of the insulating coating machine 20. Then, the insulating coating machine 20 can start cleaning and spraying the bare conductor 11. Correspondingly, rotating and adjusting the walking bracket 222 in the opposite direction allows the upper walking wheel 223 to be detached from the bare conductor 11.

[0066] Furthermore, the walking mechanism 22 also includes a first telescopic drive member 225 rotatably connected to the support base 21. The first telescopic drive member 225 is inclined, and its other end is hinged to the middle of the walking bracket 222. The first telescopic drive member 225 is telescopically adjustable, and the telescopic adjustment drives the walking bracket 222 to rotate relative to the support base 21. Preferably, the first telescopic drive member 225 is an electric cylinder; in another preferred embodiment, the first telescopic drive member 225 is a pneumatic cylinder.

[0067] Furthermore, the walking support 222 includes a vertical rod and a horizontal rod connected to the vertical rod. The end of the horizontal rod is supported and connected to the top of the vertical rod by two diagonal rods, and the bottom of the vertical rod is rotatably connected to the support seat 21 via a pivot. A walking wheel 223 is connected to the other end of the horizontal rod. The upper walking wheel 223 is rotatably mounted on a wheel seat, which is fastened to the horizontal rod by bolts.

[0068] Furthermore, the lower traveling wheel 221 is rotatably mounted on a wheel seat, the bottom of which is mounted on the support seat 221 via a first lifting drive component 227. This first lifting drive component 227 is telescopically adjustable, thereby moving the lower traveling wheel 221 up and down. Preferably, the first lifting drive component 227 is an electric cylinder, which is vertically positioned. In another preferred embodiment, the first lifting drive component 227 is a pneumatic cylinder.

[0069] Furthermore, the walking mechanism 22 also includes a first base plate 226, on which the walking bracket 222 is rotatably mounted. A first telescopic drive member 225 is fixedly connected to the first base plate 226 at a certain angle. The first base plate 226 has an opening corresponding to the bottom of the lower walking wheel 221 and a first lifting drive member 227, allowing part of the first lifting drive member 227 to be placed inside the support seat 21. By providing the first base plate 226, the walking mechanism 22 can be easily installed onto the support seat 21. During installation, it is only necessary to place the first base plate 226 on the support seat 21 and fix it to the support seat 21.

[0070] In one specific embodiment of the present invention, such as Figure 1 , Figure 5 and Figure 6As shown, the cleaning mechanism 23 includes a pair of cleaning brackets 231 rotatably adjustable on the support base 21, a rotating housing 232 rotatably mounted on the cleaning brackets 231, a plurality of bristles 233 on the outer periphery of the rotating housing 232, and a second motor 234 mounted on the cleaning brackets 231 and drivenly connected to the rotating housing 232. The pair of cleaning brackets 231 are located on both sides of the bare wire 11. By rotating the cleaning brackets 231, the rotating housing 232 can be positioned close to the bare wire 11. The second motor 234 can drive the rotating housing 232 to rotate, thereby the bristles 233 cleaning the bare wire 11.

[0071] After the walking mechanism 22 on the support 21 is attached to the bare wire 11, the cleaning mechanism 23 can be turned on to clean the bare wire 11. Specifically, the cleaning bracket 231 is rotated to attach the rotating housing 232 to the bare wire 11. The two rotating housings 232 are clamped on the bare wire 11, and then the second motor 234 is turned on to drive the two rotating housings 232 to rotate. The bristles 233 on the rotating housing 232 can sweep the bare wire 11 and clean the dust, bird droppings and other dirt on the bare wire 11.

[0072] Furthermore, combined Figure 7 and Figure 2 As shown, the rotating housing 232 has several jet holes 2321. A slip ring 235 is provided on the top of the rotating housing 232, and an air inlet pipe 236 is connected to the slip ring 235. One end of the air inlet pipe 236 communicates with the interior of the rotating housing 232, and the other end is connected to an air compressor 239 located in the support 21. The air compressor 239 generates high-pressure gas, which enters the rotating housing 232 through the air supply line and the air inlet pipe 236, and is then sprayed onto the bare wire 11 through the jet holes 2321 on the rotating housing 232, thereby cleaning the bare wire 11 and improving the cleaning effect. Preferably, the rotating housing 232 is a closed housing with a hollow interior, and the jet holes 2321 on the rotating housing 232 are staggered from the bristles 233. The slip ring 235 prevents the air inlet pipe 236 from rotating together with the rotating housing 232. The slip ring 235 is preferably a bearing, with the inner ring connected to the intake pipe 236 and the outer ring connected to the rotating housing 232 through an internally hollow bushing, the inside of which is connected to the intake pipe 236.

[0073] Furthermore, the pair of cleaning brackets 231 are staggered, so that the two rotating housings 232 can also be staggered. The cleaning bracket 231 is preferably a vertical rod, rotatably mounted on the support base 21 at the bottom, and the rotating housing 232 is connected to the top of the vertical rod.

[0074] Furthermore, the cleaning mechanism 23 also includes a second telescopic drive member 237 rotatably connected to the support base 21. The second telescopic drive member 237 is inclined, and its other end is hinged to the middle of the cleaning bracket 231. The second telescopic drive member 237 is telescopically adjustable, thereby driving the cleaning bracket 231 to rotate relative to the support base 21. Preferably, the second telescopic drive member 237 is an electric cylinder; in another preferred embodiment, the second telescopic drive member 237 is a pneumatic cylinder.

[0075] Furthermore, such as Figure 7 As shown, the rotating housing 232 is concave in the middle, and the concave middle part can be fitted onto the side of the bare wire 11 to achieve comprehensive cleaning of the bare wire 11. Preferably, the upper part of the rotating housing 232 is frustoconical, the lower part is an inverted frustoconical, and the bristles 233 are spaced apart on the surface of the rotating housing 232.

[0076] Furthermore, the cleaning mechanism 23 also includes a second base plate 238. The bottom of the cleaning bracket 231 and the second telescopic drive member 237 are rotatably connected to the second base plate 238. By setting the second base plate 238, the cleaning mechanism 23 can be easily installed on the support seat 21. During installation, it is only necessary to place the second base plate 238 on the support seat 21 and fix it to the support seat 21.

[0077] In one specific embodiment of the present invention, such as Figure 1 , Figure 8 and Figure 9 As shown, the spraying mechanism 24 includes a pair of spraying brackets 241 rotatably adjustable and mounted on a support 21, and a snap-fit ​​plate 242 mounted on the spraying brackets 241 and for attaching to the bare wire 11; the pair of spraying brackets 241 are arranged opposite to each other and located on both sides of the bare wire 11; the snap-fit ​​plate 242 is provided with a snap-fit ​​groove corresponding to the bare wire 11, and the snap-fit ​​plate 242 is also provided with a liquid supply channel communicating with the snap-fit ​​groove, the other end of which is located on the outside of the snap-fit ​​plate 242 and forms a liquid supply port. A liquid supply pipe 246 is connected to the liquid supply port. The other end of the liquid supply pipe 246 extends into the support 21 and communicates with the spray liquid storage tank provided in the support 21. A liquid pump is provided at the spray liquid storage tank, which can pump the spray liquid into the liquid supply pipe 246. Then, the spray liquid is sprayed into the snap-fit ​​groove through the liquid supply channel. The size of the snap-fit ​​groove is larger than the size of the bare wire 11. When the two snap-fit ​​grooves are snapped onto the bare wire 11, the inner surface of the snap-fit ​​groove can form a gap with the bare wire 11, so that the spray liquid can be evenly sprayed onto the bare wire 11.

[0078] Furthermore, the system also includes a positioning mechanism located near the spraying mechanism 24. This positioning mechanism is used to clamp the bare wire 11 to position it. Preferably, the positioning mechanism includes rotatable positioning wheels 243 mounted on the spraying bracket 241 and located near the snap-fit ​​plate 242. The positioning wheels 243 are horizontally positioned. When the spraying bracket 241 rotates to engage the snap-fit ​​plate 242 with the bare wire 11, the two positioning wheels 243 also clamp the bare wire 11. By using two positioning wheels 243 to clamp the bare wire 11, the bare wire 11 can be prevented from shaking during the spraying process, thus improving the spraying quality.

[0079] Furthermore, the spraying bracket 241 is preferably a vertical rod, with its bottom rotatably mounted on the support base 21, and a snap-fit ​​plate 242 connected to the top of the vertical rod.

[0080] Furthermore, the spraying mechanism 24 also includes a third telescopic drive member 244 rotatably connected to the support base 21. The third telescopic drive member 244 is inclined, and its other end is hinged to the middle of the spraying bracket 241. The third telescopic drive member 244 is telescopically adjustable, thereby driving the spraying bracket 241 to rotate relative to the support base 21. Preferably, the third telescopic drive member 244 is an electric cylinder; in another preferred embodiment, the third telescopic drive member 244 is a pneumatic cylinder.

[0081] Furthermore, the spraying mechanism 24 also includes a third base plate 245. The bottom of the spraying bracket 241 and the third telescopic drive member 244 are rotatably connected to the third base plate 245. By setting the third base plate 245, the spraying mechanism 24 can be easily installed on the support 21. During installation, it is only necessary to place the third base plate 245 on the support 21 and fix it to the support 21.

[0082] In one specific embodiment of the present invention, such as Figure 1 , Figure 10 and Figure 11As shown, the positioning clamp 25 and the obstacle-crossing clamp 25a have the same structure, both including a connecting base 251, a pair of clamping rods 252 rotatably adjustable and connected to the connecting base 251, a connecting plate 254 connected to the end of the clamping rods 252 away from the bare wire 11, a sliding rod 255 supported and connected to the connecting base 251 and close to the end of the clamping rods 252 away from the bare wire, a spring 256 sleeved on the sliding rod 255 and connected to the end of the connecting base 251 and the corresponding clamping rod 252, and a height-adjustable spring 256 mounted on the connecting base 251 and connected to the end of the clamping rods 252. A pair of connecting discs 254 have corresponding push rods 257; a clamping rod 252 has a clamp 2521 formed at one end near the bare conductor 11; a spring 256 pulls the end of the corresponding clamping rod 252 so that the clamps 2521 on the pair of clamping rods 252 are set away from each other; the top of the push rod 257 is provided with a conical push head. By moving the push rod 257 upward, the push head extends into the space between the pair of connecting discs 254, thereby causing the pair of clamping rods 252 to rotate around the middle, and then the pair of clamps 2521 move closer to each other to clamp the bare conductor 11.

[0083] A pair of clamping rods 252 are arranged crosswise, and the cross joint is rotatably connected to the connecting seat 251 via a pivot 253. The upper part of the clamping rod 252 is connected to the corresponding clamp 2521, and the lower part is connected to the corresponding connecting plate 254. The clamp 2521 has a V-shaped groove corresponding to the bare wire 11, which can clamp the corresponding bare wire 11. The lower part of the clamping rod 252 has a through hole corresponding to the sliding rod 255, and the sliding rod 255 passes through the through hole and is supported and connected in the connecting seat 251.

[0084] Furthermore, a vertically arranged connecting plate is connected to the bottom of the connecting seat 251. The connecting plate on the connecting seat 251 of the positioning clamp 25 is inserted into the bearing seat 21, and the connecting seat 251 is placed on the bearing seat 21. The connecting plate of the connecting seat 251 of the obstacle-crossing clamp 25a is connected to the fourth telescopic drive member 29, which is supported and connected between the side of the bearing seat 21 and the connecting plate. The fourth telescopic drive member 29 can be telescopically adjusted. Preferably, the fourth telescopic drive member 29 is an electric cylinder; in another preferred embodiment, the fourth telescopic drive member 29 is a drive cylinder.

[0085] Furthermore, a second lifting drive component 258 is provided at the bottom of the connecting seat 251. This second lifting drive component 258 is connected to the top rod 257 and can be adjusted in height, thereby moving the top rod 257 in a vertically adjustable manner. Preferably, the second lifting drive component 258 is an electric cylinder, which is vertically arranged. In another preferred embodiment, the second lifting drive component 258 is a pneumatic cylinder.

[0086] In one specific embodiment of the present invention, such as Figure 1 , Figure 12 and Figure 13As shown, the insulating coating machine 20 of the present invention also includes a hanging mechanism 26 provided on the support base 21. The hanging mechanism 26 is provided with a retractable and adjustable lifting strap 261 and a hook 262 connected to the end of the lifting strap 261.

[0087] The hook 262 can be attached to the corresponding bare conductor, and the load-bearing seat 21 can be lifted or lowered by retracting the lifting sling 261.

[0088] Furthermore, two hooks 262 and two lifting straps 261 are provided. The two hooks 262 are connected and fixed by a transverse positioning plate 263, which has two notches for hooking, providing space for the drone to be hooked. A shaft 266 is rotatably connected to the support 21, and the ends of the two lifting straps 261 are fixedly connected to the shaft 266. The shaft 266 can be rotated and adjusted to retract the lifting straps 261. Furthermore, a third motor 267 is provided inside the support 21. The third motor 267 is driven by the shaft 266 through a synchronous belt and a synchronous pulley. Thus, the third motor 267 can drive the shaft 266 to rotate through the synchronous belt and the synchronous pulley to retract the lifting straps 261. Preferably, the shaft 266 is located in the middle of the support 21, which can ensure that the support 21 remains balanced during hooking.

[0089] Furthermore, the mounting mechanism 26 also includes a rotatable guide wheel 264 located on the side of the support seat 21 and a telescopically adjustable limiting wheel 265 located inside the support seat 21; the limiting wheel 265 and the guide wheel 264 are located on the same side of the support seat 21, and the side where the guide wheel 264 is located is adjacent to the side where the obstacle-crossing clamp 25a is located; the side of the support seat 21 has an opening 211 communicating with the interior corresponding to the limiting wheel 265; the lifting belt 261 can pass over the upper part of the guide wheel 264, then pass over the lower part of the limiting wheel 265, and then lift the support seat 21 through the hook 262, so that the support seat 21 is in a vertical state with the side where the guide wheel 264 is located facing upwards. This state is as follows Figure 15 As shown.

[0090] When the insulating coating machine 20 needs to be hoisted, the hoisting sling 261 is passed around the guide wheel 264 and the limit wheel 265 on the ground. Then, the hoisting sling 261 is released, and the hook 262 at the end of the hoisting sling 261 is hooked onto the corresponding bare conductor 11. At this time, the hook 262 can be hooked onto the bare conductor 11 by a drone. The hook 262 is relatively light, and the drone can fully support the hook 262 and complete the high-altitude hooking of the hook 262. This can save the need for manual climbing to hook the hook, ensuring personnel safety and making the hooking operation simpler and more convenient. Then, the hoisting sling 261 is wound up, and the support seat 21 is gradually moved upward until it approaches the bare conductor 11. Then the limit wheel 265 is retracted. After the lifting sling 261 loses its limit, it quickly becomes vertical. The bearing seat 21 is straightened under the action of gravity. Then the lifting sling 261 is continued to be wound up, allowing the bearing seat 21 to continue to approach the bare conductor 11 until the traveling mechanism 22 on the bearing seat 21 can clamp onto the bare conductor 11. At this time, the hook 262 can be released from the connection between it and the bare conductor 11.

[0091] A freely rotatable shaft is provided on the side of the support base 21, and a fixed guide wheel 264 is sleeved on the shaft. A telescopic adjustment component is provided inside the support base 21, which is connected to a limiting wheel 265. The limiting wheel 265 is rotatably connected to the telescopic adjustment component, and the telescopic adjustment of the telescopic adjustment component can extend and retract together with the limiting wheel 265. Preferably, the telescopic adjustment component is an electric cylinder; in another preferred embodiment, it is a telescopic pneumatic cylinder.

[0092] Furthermore, an inclined guide plate 212 is provided on the side of the support 21. One end of the guide plate 212 is connected to the bottom surface of the support 21, and the other end extends upward and outward from the support 21. By providing the guide plate 212, collisions with other bare wires 11 can be avoided during the hoisting of the insulating coating machine 20.

[0093] Furthermore, such as Figure 1 , Figure 14 and Figure 15As shown, the insulating coating machine 20 also includes a hook-and-unhook mechanism 27, which is located near the shaft 266. This mechanism is used to remove the hook 262 from the bare conductor 11 after the insulating coating machine 20 is hoisted into place and the traveling mechanism 22 is clamped onto the bare conductor 11. The hook-and-unhook mechanism 27 includes a third lifting drive 271 erected on the support base 21, a transverse pusher 272 located on top of the third lifting drive 271, and a tray plate 273 connected to the transverse pusher 272. The third lifting drive 271 is adjustable in height, and it can be adjusted in height along with the transverse pusher 272 and the tray plate 273. The transverse pusher 272 is telescopically adjustable, allowing the tray plate 273 to be pushed and pulled. The tray plate 273 has a V-shaped groove. After the limit wheel 265 retracts and the bearing seat 21 is aligned, the card plate 273 is located below the transverse positioning plate 263 connected to the hook 262. After the hoisting sling 261 is wound into place, the V-shaped slot of the card plate 273 can be fitted onto the transverse positioning plate 263 by adjusting the lifting of the third lifting drive 271 and the extension of the transverse push 272. Then, the hook 262 is disengaged from the bare wire 11 by adjusting the upward movement of the third lifting drive 271. Next, the hook 262 is disengaged from the bare wire 11 by retracting the transverse push 272. Finally, the third lifting drive 271 and the transverse push 272 can be reset.

[0094] Furthermore, a lever 268 is supported on the support base 21. The lever 268 has fifth telescopic drive members at both ends, which are rotatably mounted on the support base 21 and are arranged at an angle. The fifth telescopic drive members are adjustable in length and retraction, allowing the lever 268 to change position, enabling it to contact the lifting belt 261 and thus change the orientation of the lifting belt 261. This ensures that the belt avoids the bare overhead wires during the retrieval and lowering of the painting machine, preventing interference. When the insulating coating machine 20 is lowered, the support base 21 is in a horizontal state. Since the V-shaped groove of the hook-and-unhook mechanism 27's card plate 273 supports the horizontal positioning plate 263, the position of the horizontal positioning plate 263 can be adjusted by the third lifting drive 271 and the horizontal drive 272, so that the hook 262 hooks onto the bare conductor 11. Then the third lifting drive 271 and the horizontal drive 262 are reset, the traveling mechanism releases the clamp on the bare conductor 11, and then the hoisting sling 261 is released, so that the insulating coating machine 20 can be lowered gradually. During the lowering process, the position of the lever 268 can be adjusted by the fifth telescopic drive, thereby changing the position of the hoisting sling 261, avoiding interference between the hoisting sling 261 and the bare conductor below, and ensuring that the insulating coating machine 20 can be smoothly lowered to the ground. Specifically, when there is another bare conductor below, when the coating machine is about to contact the bare conductor below, the angle of the lifting belt 261 is changed by using the lever 268, so that the bearing seat 21 can move away from the bare conductor below and avoid interference.

[0095] like Figure 1 , Figure 2 and Figure 12 As shown, the interior of the support base 21 has an accommodating space that can accommodate structures such as the third motor 267, the spray liquid storage tank, and the air compressor 239. A battery pack 28 is also provided inside the support base 21, which is used to provide power to the driving and motor components of each mechanism.

[0096] The working process of the self-propelled bare conductor coating machine for applying insulating coating to live bare conductors according to the present invention will be described below.

[0097] like Figure 13 As shown, the support base 21 is erected on the ground with the side equipped with the guide wheel 264 facing upwards. The lifting sling 261 is then passed over the top of the guide wheel 264 and then over the bottom of the limiting wheel 265. At this point, the limiting wheel 265 is extended and located at the opening 211 on the side of the support base 21. Then, the third motor 267 is started in reverse, driving the shaft 266 to rotate and release the lifting sling 261. After the lifting sling 261 has been released to a certain length, the hook 262 is attached to the corresponding bare conductor 11. Figure 15As shown, hook 262 can be attached to bare conductor 11 using a drone. Then, the third motor 267 is started to rotate forward, driving shaft 266 to rotate to reel in lifting strap 261, thereby gradually moving the support seat 21 upward until it approaches the bare conductor 11.

[0098] After the support seat 21 approaches the bare conductor 11 at a certain distance, the limiting wheel 265 retracts, releasing the restriction on the lifting sling 261. The lifting sling 261 quickly becomes vertical, with the lifting point at the position of the shaft 266, and the support seat 21 straightens under its own weight. Then, the third motor 267 continues to rotate forward, and the shaft 266 rotates to reel in the lifting sling 261 until the lower traveling wheel 221 of the traveling mechanism 22 on the support seat 21 contacts the bare conductor 11. Then, the first telescopic drive member 225 extends to allow the traveling bracket 222 to rotate and adjust, so that the upper traveling wheel 223 is hooked onto the upper part of the bare conductor 11, and then the upper traveling wheel 223 and the lower traveling wheel 221 clamp the bare conductor 11. After the traveling mechanism 22 completes the hooking with the bare conductor 11, the hook 262 can be removed from the bare conductor 11 using the hook-and-unhook mechanism 27.

[0099] Then, the second telescopic drive member 237 extends to allow the rotating housing 232 to engage with the bare wire 11. Next, the second motor 234 is activated to drive the rotating housing 232 to rotate, causing the brush bristles 233 to clean the bare wire 11. Simultaneously, the air compressor 239 is activated to provide high-pressure gas to the rotating housing 232. The high-pressure gas is ejected from the jet nozzle 2321 to blow clean the bare wire 11. The cleaning mechanism 23 cleans the bare wire 11, while the traveling mechanism 22 travels along the bare wire 11, thus cleaning it thoroughly. When encountering an obstacle, the fourth telescopic drive member 29 extends, allowing the obstacle-crossing clamp 25a to clamp the corresponding part of the bare wire 11. This causes the mechanism encountering the obstacle to release its grip on the bare wire 11. Then, the fourth telescopic drive member 29 retracts to pull the support seat 21, allowing the corresponding mechanism to cross the obstacle. This process is repeated to allow each mechanism to cross obstacles sequentially.

[0100] After the bare wire 11 is cleaned, the spraying mechanism 24 can be used to spray the bare wire 11. The clamping plate 242 of the spraying mechanism 24 is clamped on the bare wire 11. The liquid pump pumps the spraying liquid in the liquid storage tank into the clamping plate 242, so that the spraying liquid can be evenly coated on the bare wire 11. During the operation of the spraying mechanism 24, it moves along the bare wire 11 through the walking mechanism 22 to achieve comprehensive spraying of the bare wire 11.

[0101] After the spraying operation is completed, the hook 262 is attached to the bare conductor 11 using the hook-and-unhook mechanism 27. The third motor 267 reverses to release the hoisting sling 261, and the bearing seat 21 gradually moves down. The fifth telescopic drive connected to the lever 268 is retracted to change the position of the hoisting sling 261, so as to avoid interference with the bare conductor below during the lowering. After the bearing seat 21 reaches the ground, the hook 262 can be removed from the bare conductor 11 using a drone.

[0102] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. 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.
