Description

Technical Field

[0001] This invention relates to the field of spraying equipment technology, and in particular to a climbing pole spraying device. Background Technology

[0002] In power transmission systems, power poles are crucial supports for overhead transmission lines. They typically consist of vertically inserted poles, connecting tower frames, insulators mounted on the frames, and bare conductors connected to the insulators. Because bare conductors are exposed to the atmosphere for extended periods, they are susceptible to corrosion and environmental factors that can affect their insulation performance and lifespan. Therefore, it is frequently necessary to coat their surfaces with insulating protective materials, such as insulating varnishes or coatings, to enhance their electrical insulation, weather resistance, and corrosion resistance. Effective and uniform coating of power poles, especially high-altitude bare conductors, is an important task in power equipment maintenance.

[0003] For a long time, spraying coating on poles, especially bare conductors crossing towers, has mainly relied on manual labor. Operators typically need to hold a long pole equipped with a spray nozzle, climb to a suitable height on the tower, or raise it as high as possible on the ground, visually locating and aligning the spraying position on the conductor. This method has significant drawbacks: extremely low efficiency, high labor intensity for workers, safety hazards associated with working at heights; difficulty in maintaining a stable spray nozzle position for extended periods, resulting in poor coating uniformity, incomplete coverage, and unsatisfactory coating effects; and particularly difficult to perform fine spraying on complex areas near the tower.

[0004] To improve automation, drones have been used to carry painting equipment in recent years. For example, Chinese Patent Publication No. CN116062169A discloses a multi-purpose drone painting device that uses a painting mechanism mounted below the drone and an anti-collision mechanism to mitigate the risks of close-range operations. However, this type of drone painting solution has significant drawbacks: First, drones consume a lot of power and have limited endurance, making them unsuitable for tasks requiring long-term, detailed painting. Second, drones operating near complex environments such as high-voltage power lines face a high risk of malfunction, as their high-speed rotating propellers pose a significant risk of scratching or even cutting wires or becoming entangled in insulator strings. Third, even with anti-collision buffers, precise hovering and attitude stabilization of the drone in confined spaces are extremely difficult, testing its "point-to-point painting capability." This directly results in difficulty achieving uniform and dense precise painting of bare wires, typically only allowing for large-area, coarse painting. This not only wastes paint but also easily causes paint to spread and fly due to airflow disturbances, polluting the environment and resulting in low actual adhesion.

[0005] Therefore, there is an urgent need for a safer, more efficient, and automated spraying solution suitable for pole and tower environments. Summary of the Invention

[0013] Specifically, the vehicle is equipped with several first cameras facing the passage on its top; and at least one of the wheels can move autonomously along the circumference of the tower surface to adjust the direction of the notch.

[0014] Specifically, there are two positioning components, which are located on both sides of the channel and arranged opposite each other, and the surface of the wheel is provided with anti-slip texture.

Detailed Implementation

[0029] This invention provides a climbing pole spraying device. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0030] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0031] like Figure 1 and Figure 2 As shown, the pole tower is a key facility supporting overhead transmission lines. It typically consists of two vertically inserted tower poles 41, a tower frame 42 connecting the two tower poles 41, insulators 43 mounted on the tower frame 42, and bare conductors 44 connected to the insulators 43. Since the bare conductors 44 are exposed to the atmosphere for extended periods, they are susceptible to corrosion and environmental factors that affect their insulation performance and service life. Therefore, it is necessary to coat their surface with insulating protective materials. This embodiment provides a climbing pole tower spraying device for spraying bare conductors 44.

[0032] Please refer to Figures 1 to 7 This embodiment of a climbing tower spraying device includes a climbing mechanism 10 and a spraying mechanism 20 mounted on the climbing mechanism 10. The climbing mechanism 10 includes a carrier 11 and a traveling assembly 13 mounted on the carrier 11. The traveling assembly 13 travels vertically along the tower 41. The carrier 11 has a vertically penetrating channel 12. Multiple traveling assemblies 13 are distributed circumferentially along the channel 12. The traveling assemblies 13 can be radially and adaptively adjusted in position along the channel 12. The side of the carrier 11 has a notch for avoiding the tower 42. 14; The spraying mechanism 20 includes a linear guide rail 21 that moves synchronously with the carrier 11, a first sliding seat 22 that is slidably connected to the linear guide rail 21, a first rotary driver 23 that is fixed to the first sliding seat 22, a telescopic driver 24 that is connected to the output end of the first rotary driver 23, a mounting base 25 that is connected to the output end of the telescopic driver 24, and a spraying assembly 26 that is mounted on the mounting base 25; The spraying assembly 26 includes an arc-shaped material tube 261 and a plurality of nozzles 262 connected to the arc-shaped material tube 261.

[0033] In this embodiment, the climbing tower spraying device first places the climbing mechanism 10 on the bottom of one of the towers 41, so that the tower 41 is located in the channel 12 of the carrier 11. The walking component 13 surrounds the channel 12 and contacts the surface of the tower 41. By adaptively adjusting its position radially to adapt to the change in the diameter of the tower 41, it ensures that the carrier 11 can move stably vertically along the tower 41. After the climbing mechanism 10 is activated, it starts to climb from the bottom of the tower 41. When encountering transverse connecting structures such as tower 42, the notch 14 on the side of the carrier 11 can avoid the tower 42, allowing the entire device to continue climbing to the height of the bare conductor 44. After reaching the position of the bare conductor 44, the spraying mechanism 20 is activated. The first sliding seat 22 slides laterally along the linear guide rail 21 to adapt to the span of the bare conductor 44. The first rotary driver 23 drives the telescopic driver 24 and the mounting base 25 to rotate and adjust the spraying angle. The telescopic driver 24 extends or retracts to control the spraying distance. Finally, the arc-shaped material tube 261 of the spraying assembly 26 is aligned with the bare conductor 44, and multiple nozzles 262 spray the surface of the bare conductor 44 evenly from different directions to achieve full coverage spraying.

[0034] The climbing tower spraying device in this embodiment enables automatic climbing of the tower 41 and flexible avoidance of the tower 42 without the need for manual or drone intervention; the spraying mechanism 20, through lateral movement, angle rotation and position extension adjustment, combined with a multi-nozzle design, significantly improves the spraying efficiency and coverage uniformity of the bare conductor 44, avoiding paint waste and safety risks.

[0035] like Figure 3 and Figure 4 As shown, the carrier 11 includes a first frame 111, a second frame 112 hinged to one end of the first frame 111, and a locking assembly 113 for locking the first frame 111 and the second frame 112 together. A notch 14 is formed at the end of the first frame 111 and the second frame 112 away from their hinge axis. The locking assembly 113 includes an arc-shaped extension plate 1131 fixed to the first frame 111 and a locking screw 1132 for locking the arc-shaped extension plate 1131 and the second frame 112 together. Before the climbing mechanism 10 is installed on the tower 41, the operator first rotates the second frame 112, hinged to one end of the first frame 111, away from the tower 41 about their hinge axis, so that the first frame 111 and the second frame 112 are in an open state. At this time, the cylindrical frame is separated into two approximately semi-circular parts. The carrier 11 is then laterally moved to the side of the tower 41, so that the tower 41 is embedded in the open space formed by the first frame 111 and the second frame 112. Next, the second frame 112 is rotated in the opposite direction to close towards the first frame 111 until the two are assembled into a complete cylindrical frame that wraps around the tower 41. At this point, the arc-shaped extension plate 1131 of the locking assembly 113 is fitted against the edge of the second frame 112, and the locking screw 1132 is tightened through the corresponding screw holes of the arc-shaped extension plate 1131 and the second frame 112 to lock them in place. This completely locks the first frame 111 and the second frame 112 together to form a channel 12, preventing relative displacement between the two during climbing or operation.

[0036] The design of the openable vehicle 11, through the combination of a split frame structure and a hinge and locking assembly 113, solves the problem that traditional integral frames cannot be directly fitted into the tower 41; its closed cylindrical frame tightly wraps around the tower 41, ensuring the stable climbing of the walking assembly 13, and maintaining the automatic avoidance function of the tower 42 through the notch 14, significantly improving installation efficiency and structural adaptability.

[0037] like Figure 4 and Figure 5As shown, the traveling assembly 13 includes a swing arm 131 hinged to the carrier 11, a tracked traveling device 132 hinged to the other end of the swing arm 131, a first slider 133 sliding vertically on the carrier 11, a connecting rod 134 hinged between the first slider 133 and the tracked traveling device 132, and a first push-pull driver 135 disposed on the carrier 11 for driving the first slider 133. The tracked traveling device 132 includes a traveling bracket 1321, a drive shaft and a driven shaft 1322 rotatably mounted on the traveling bracket 1321, a track 1323 sleeved around the outside of the drive shaft and the driven shaft 1322, and a first motor 1324 fixed on the traveling bracket 1321 for driving the drive shaft to rotate. The first push-pull actuator 135 drives the first slider 133 to slide vertically along the carrier 11, and pushes the tracked walking device 132 to swing around the hinge point of the swing arm 131 through the connecting rod 134, realizing the adaptive extension and retraction of the tracked walking device 132 along the radial direction of the channel 12, so that it always keeps in close contact with the surface of the tower 41; the climbing action is driven by the active rotation of the track of the tracked walking device 132 itself, which drives the entire carrier 11 to rise and fall stably along the surface of the tower 41. This design achieves radial adaptive adjustment synchronously through a single actuator, while the track rotation provides the core climbing power. It has a compact structure and high reliability, significantly improving the adaptability of the device to changes in the external dimensions of the tower 41 and the climbing stability.

[0038] In a preferred embodiment, the climbing mechanism 10 further includes a positioning component 15 disposed on the carrier 11. The positioning component 15 includes a first slide rail 151 radially fixed to the carrier 11 along the channel 12, a second slider 152 slidably engaged with the first slide rail 151, a second push-pull driver 153 fixed to the carrier 11 and used to drive the second slider 152, a V-shaped wheel frame 154 fixed to the second slider 152, and two wheels 155 rotatably disposed on the V-shaped wheel frame 154 with their central axis arranged vertically. When the climbing mechanism 10 climbs to the working height of the bare conductor 44, the second push-pull driver 153 drives the second slider 152 to move radially along the first slide rail 151 toward the center of the channel 12, driving the V-shaped wheel frame 154 to advance synchronously, so that the two wheels 155 mounted on it press against the surface of the tower 41 from both sides; since the central axis of the wheel 155 is perpendicular to the axis of the tower 41, after pressing, it forms a strong friction with the surface of the tower 41, instantly locking the vertical position of the carrier 11 and preventing the climbing mechanism 10 from accidentally slipping during the spraying operation. The mechanical self-locking provides height positioning protection, ensuring that the carrier 11 is stably stopped, creating safe working conditions for the spraying mechanism 20.

[0039] Furthermore, the top of the vehicle 11 is equipped with several first cameras 16 facing the passage 12; and at least one wheel 155 can autonomously move along the circumference of the tower 41 surface to adjust the direction of the gap 14. During operation, the first cameras 16 on the top of the vehicle 11 monitor obstacles (such as the tower 42) on the top of the device's travel direction in real time; when the ground personnel observe the obstacle through the remote control, the remote control command drives the positioning component 15 to extend, so that the wheel 155 presses against the tower 41 to achieve temporary fixation, and then starts the wheel 155, which can autonomously move along the circumference of the tower 41 surface, to rotate. In order to achieve autonomous movement of the wheel 155, a second motor (not shown) can be added to the corresponding V-shaped wheel frame 154 of the wheel 155. The second motor drives the wheel 155 to move around the outer side of the tower 41 circumferentially. The rotation of the wheel 155 causes the vehicle 11 to rotate around the tower 41 as the axis, thereby accurately adjusting the orientation of the gap 14 to avoid the obstacle structure and achieve aerial turning of the entire machine's attitude. The climbing tower spraying device of this embodiment has omnidirectional obstacle avoidance and autonomous attitude adjustment capabilities, breaking through the movement limitations of traditional climbing equipment and significantly improving the adaptability to complex tower environments.

[0040] like Figure 7 As shown, there are two positioning components 15, located on opposite sides of the channel 12. The wheels 155 have anti-slip textures on their surfaces. The two opposing positioning components 15 operate synchronously during locking: two second push-pull actuators 153 drive the second sliders 152 on both sides radially along the first slide rail 151, causing the V-shaped wheel frame 154 and the wheels 155 with anti-slip textures to symmetrically press against the tower rod 41 from both sides of the channel 12. The anti-slip textures on the wheels 155 increase the contact friction between them and the surface of the tower rod 41, and combined with the constraint effect of the vertically arranged wheel axles, achieve double anti-slip locking. This embodiment uses symmetrical clamping forces to prevent the carrier 11 from tilting, and the anti-slip textures significantly improve the anti-slip capability, ensuring the positioning rigidity and operational safety of the device under complex working conditions.

[0041] like Figure 3 and Figure 4 As shown, the spraying mechanism 20 also includes a second rotary driver 27 fixed to the carrier 11, and a linear guide rail 21 fixed to the output end of the second rotary driver 27. During the climbing phase of the climbing mechanism 10, the second rotary driver 27 drives the linear guide rail 21 to rotate axially around its output end, causing the linear guide rail 21 to rotate and retract from its lateral state during operation to a vertical position parallel to the tower 41, and close to the outside of the carrier 11; when the device reaches the predetermined spraying height, the second rotary driver 27 drives the linear guide rail 21 to rotate in the opposite direction again, causing it to unfold from its vertical state to a horizontal position, and position it in an operating posture close to the side of the tower 42.

[0042] Folding and storage significantly reduces the horizontal space occupied, preventing the long linear guide rail 21 from colliding with the tower 42 or insulator 43 during climbing; when unfolded, the linear guide rail 21 is placed horizontally and located on the side of the tower 42, which facilitates the subsequent adjustment of the position of the spraying assembly 26 for spraying.

[0043] like Figure 3 As shown, a second camera 28 is mounted on the mounting base 25, facing the center of the curved material tube 261. During the spraying process, the second camera 28, fixed to the mounting base 25, is aimed at the central area of ​​the curved material tube 261 in real time, clearly capturing the coating coverage effect, atomization state, and coating adhesion of the bare wire 44 by multiple nozzles 262; the captured images are simultaneously transmitted to the display screen of the ground remote controller, allowing the operator to remotely observe the spraying quality in real time. This achieves dynamic visual monitoring of the spraying process, facilitating precise adjustment of spraying parameters, significantly avoiding problems such as incomplete spraying, uneven coverage, or missed spraying, and greatly improving the reliability of the bare wire 44 spraying quality.

[0044] like Figure 4 As shown, the climbing tower spraying device also includes a material blocking mechanism 30. The material blocking mechanism 30 and the spraying mechanism 20 are respectively located on both sides of the notch 14. The material blocking mechanism 30 includes an arc-shaped guide rail 31 fixed on the carrier 11, a second sliding seat 32 sliding along the arc-shaped guide rail 31, a third rotary driver 33 fixed on one side of the second sliding seat 32, and a material blocking component 34 connected to the output end of the third rotary driver 33 and adjustable to the bottom of the spraying assembly 26. A third motor 321 is provided on the top of the second sliding seat 32 as a power source. The output end of the third motor 321 is connected to a pulley 322. The pulley 322 is driven by the third motor 321 to move along the arc-shaped guide rail 31, thereby driving the entire second sliding seat 32 to slide along the arc-shaped guide rail 31. During the climbing phase, the material-blocking mechanism 30 is in a retracted state. Specifically, the third rotary driver 33 drives the material-blocking component 34 to rotate around the output end axis to a vertical position and closely adhere to the outside of the carrier 11. Simultaneously, the second sliding seat 32 slides along the arc-shaped guide rail 31 away from the notch 14, completely avoiding the space of the notch 14 and ensuring unobstructed lifting of the entire device. During operation, the device can be switched to the material-blocking state. The second sliding seat 32 slides in the opposite direction along the arc-shaped guide rail 31 towards the notch 14, and the third rotary driver 33 drives the material-blocking component 34 to rotate 90° to a horizontal position, so that the material-blocking component 34 is precisely laid flat directly below the spraying assembly 26.

[0045] This embodiment completely eliminates the interference of the material blocking component 34 on the climbing channel by folding and sliding to avoid contamination; after unfolding, it is precisely positioned to receive dripping paint, avoiding contamination of the electrical equipment below (such as transformers), and ensuring a safe and clean spraying environment.

[0046] like Figure 6As shown, the baffle 34 includes a frame 341, a collection trough 342 disposed on the upper end face of the frame 341, and an inner cavity disposed inside the frame 341 and connected by a plurality of through holes 343. The collection trough 342 is used to collect dripping paint, which then flows into the inner cavity through the through holes 343 for storage, so as to realize subsequent recycling.

[0047] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of the present invention.

The vehicle (11) is equipped with several first cameras (16) facing the channel (12) on its top; and at least one of the wheels (155) can move autonomously along the circumferential surface of the tower (41) to adjust the direction of the notch (14); a second motor for driving the wheel (155) to rotate is installed on the V-shaped wheel frame (154); the first cameras (16) on the top of the vehicle (11) monitor obstacles at the top of the travel direction in real time; When ground personnel observe an obstacle via remote control, the remote control command drives the positioning component (15) to extend, causing the wheel (155) to press against the tower (41) for temporary fixation. Subsequently, the second motor drives the wheel (155) to move circumferentially around the outer side of the tower (41). The rotation of the wheel (155) causes the vehicle (11) to rotate around the tower (41) as an axis, thereby precisely adjusting the orientation of the notch (14) to avoid the obstacle structure and achieving aerial turning of the entire machine's attitude. The positioning component (15) has two parts, and the two positioning components (15) are respectively located on both sides of the channel (12) and are arranged opposite to each other. The surface of the wheel (155) is provided with anti-slip texture. The mounting base (25) is provided with a second camera (28) facing the middle of the arc-shaped tube (261); The baffle (34) includes a frame (341), a collection groove (342) located on the upper end face of the frame (341), and an inner cavity located inside the frame (341) and connected by several through holes (343).
