Description

Technical Field

[0001] This invention belongs to the field of inspection robot technology, and in particular relates to a high-altitude operation robot. Background Technology

[0002] Currently, power system and high-rise building inspections mainly rely on aerial work robots. To meet the load requirements of carrying infrared imaging, lidar, and various robotic arms, existing aerial work robots typically use aluminum alloy or high-strength steel as their frame. While this design ensures structural rigidity, it results in the entire machine weighing tens of kilograms, placing stringent requirements on the support load of the working environment.

[0003] Due to the redundant weight of the equipment, the on-site deployment process is exceptionally complex, typically requiring multiple operators and large lifting machinery to complete the mounting. The overall system redundancy is extremely high, and on-site assembly and dismantling times are lengthy, making it difficult to meet the needs of rapid emergency response in the event of sudden failures. Furthermore, the significant weight increases the starting torque and operating load of the motors, severely limiting the robot's endurance for prolonged high-altitude operations and shortening the coverage area of ​​a single inspection. Regarding the mounting structure, existing high-altitude cable robots mostly employ single-sided mounting or open pressure roller structures. In complex environments such as high-altitude winds, cable tilting, or the presence of swaying foreign objects, this incompletely constrained mounting method poses a very high risk of derailment. If a detachment occurs, the heavy metal body could cause incalculable secondary disasters to ground personnel and delicate electrical facilities. The cameras of existing inspection equipment are mostly fixed or rotate within a small range, and the field of view is severely obstructed by the body structure. When traveling along the cable, they can often only monitor directly below or at a specific angle. They cannot perform synchronous and comprehensive digital scanning of the entire circumference of the cable, tower connectors, and complex ground environment. This limitation of the field of view leads to low inspection efficiency and makes it easy to miss critical minor defects. Summary of the Invention

[0006] In the aerial work robot of the present invention, the power box includes a first housing and a second housing, the first housing and the second housing forming an installation cavity, the first housing and the second housing being fixedly connected by bolts, an installation plate being fixedly attached to the inner top wall of the first housing, and two driven wheels being rotatably connected to the installation plate and arranged sequentially along the length direction of the cable.

[0007] In the aerial work robot of the present invention, a sliding plate is vertically slidably connected inside the first housing, and an elastic traction component is provided between the sliding plate and the first housing. The driving wheel is rotatably connected to one side of the sliding plate and located below the two driven wheels. The first power mechanism is mounted on the sliding plate and is drivenly connected to the driving wheel. The elastic traction component causes the driving wheel and the driven wheel to clamp the cable.

[0008] In the aerial work robot of the present invention, the first power mechanism includes a second driving member fixedly mounted on the sliding plate. The output end of the second driving member is connected to a reducer. The reducer is fixedly mounted on the sliding plate. The output end of the reducer is connected to the drive wheel. The second driving member drives the drive wheel to rotate through the reducer, thereby moving the power box along the cable.

[0009] In the aerial work robot of the present invention, a movable handle is fixedly connected to the bottom end of the sliding plate. The movable handle extends through the bottom surface of the first housing. A fixed handle is fixedly connected between the bottom ends of the first housing and the second housing. The fixed handle and the movable handle are correspondingly arranged. By gripping the fixed handle and the movable handle, the distance between the driving wheel and the driven wheel is increased, which facilitates the cable to enter between the driving wheel and the driven wheel.

[0010] In the aerial work robot of the present invention, the fixed plate is fixedly connected to the second housing, and the fixed plate has an annular cavity for the movement of the detection mechanism on the side away from the second housing. The annular cavity is coaxially arranged with the cable, and the second power mechanism is arranged in the annular cavity.

[0011] In the aerial work robot of the present invention, the second power mechanism includes a drive component and a moving component mounted on a mounting frame; The movable component includes at least two pulleys, which are rotatably connected to the mounting frame and rollably connected within a slide rail, which is circumferentially formed at the inner edge of the annular cavity.

[0012] In the aerial work robot of the present invention, the drive assembly includes a first drive member fixedly mounted on the mounting frame. The first drive member is connected to a gear, which is rotatably connected to the mounting frame.

[0013] In the aerial work robot of the present invention, the detection mechanism includes a mounting block, which is fixedly mounted on the mounting frame. A camera is fixedly mounted on the mounting block, and the camera end of the camera faces the cable.

[0014] Compared with the prior art, the present invention has the following advantages and technical effects: This invention proposes a high-altitude operation robot. The power unit is made of ASA, PLA, or ABS material, significantly reducing the overall weight compared to traditional metal bodies. This allows the device to be carried and quickly deployed by a single person in field power cable installations, solving the problem that traditional metal inspection equipment requires multiple people and large lifting machinery for on-site deployment due to its excessive weight. The power unit incorporates a sliding clamping mechanism, including at least two driven wheels and at least one driving wheel. The driving wheel is located below and between the two driven wheels, with the cable positioned between the driving wheel and the two driven wheels, forming a three-point radial constraint structure. Compared to existing single-sided mounting or open pressure wheel structures, this design physically eliminates the risk of derailment under conditions of strong winds, cable tilting, or object movement, preventing secondary disasters caused by the heavy metal body falling and damaging personnel and power facilities on the ground. A second power mechanism is installed on the fixed plate on one side of the power box. This second power mechanism drives the detection mechanism to rotate around the cable, enabling the detection end of the detection mechanism to detect the cable from multiple angles. This breaks through the problem of limited viewing angle caused by the fixed installation or small-range rotation of traditional cameras, and realizes multi-dimensional monitoring of the entire circumference of the cable, tower connectors and ground environment, eliminating blind spots in inspection and improving inspection efficiency.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Reference Figures 1 to 4 The present invention discloses a high-altitude operation robot, comprising: a power box, a first opening on one side of the power box for a cable to pass through, the first opening penetrating the power box, a sliding clamping mechanism disposed inside the power box, the sliding clamping mechanism being drivenly connected to a first power mechanism, the cable passing through the first opening and clamped on the sliding clamping mechanism, the first power mechanism driving the sliding clamping mechanism to make the power box move along the cable; A fixed plate 3 is provided on one side of the power box, and a second opening is provided on the fixed plate 3. The second opening is corresponding to the first opening. A second power mechanism is provided on the fixed plate 3. A detection mechanism is provided on the second power mechanism. The detection end of the detection mechanism faces the cable. The second power mechanism drives the detection mechanism to rotate around the cable. The sliding clamping mechanism includes at least two driven wheels 15 and at least one driving wheel 14, with the driving wheel 14 located below the two driven wheels 15 and between the two driven wheels 15, and the cable located between the driving wheel 14 and the two driven wheels 15. The power box is made of materials including ASA, PLA, and ABS.

[0019] During operation, the cable enters and passes through the power box through the first opening on one side. The cable is clamped between the driving wheel 14 and two driven wheels 15 of the sliding clamping mechanism, with the driving wheel 14 positioned below and between the two driven wheels 15, forming a triangular arrangement. The first power mechanism drives the sliding clamping mechanism, causing friction between the driving wheel 14, driven wheels 15, and the cable, thereby moving the power box along the cable. A second power mechanism is mounted on the fixed plate 3 on one side of the power box. This second power mechanism drives the detection mechanism to rotate around the cable, with the detection end of the detection mechanism always facing the cable for detection. The power box is made of ASA, PLA, or ABS material.

[0020] By employing a three-point clamping structure formed by the driving wheel 14 and two driven wheels 15, radial constraints are applied to the cable, physically preventing the robot from derailing during movement and improving the safety of high-altitude operations. The second power mechanism drives the inspection mechanism to rotate around the cable, enabling it to inspect the cable from multiple angles, breaking the limitations of traditional fixed viewing angles and eliminating blind spots. The power box uses lightweight polymer materials such as ASA, PLA, and ABS, significantly reducing the overall weight compared to traditional metal bodies. This allows the equipment to be carried and quickly deployed by a single person, solving the transportation and installation problems caused by the excessive weight of traditional metal inspection equipment.

[0021] In one alternative embodiment, the power box includes a first housing 1 and a second housing 2, which together form an installation cavity. The first housing 1 and the second housing 2 are fixedly connected by bolts. An installation plate 19 is fixedly attached to the inner top wall of the first housing 1. Two driven wheels 15 are rotatably connected to the installation plate 19 and are arranged sequentially along the length of the cable.

[0022] The power box consists of a first housing 1 and a second housing 2, which are bolted together to form a mounting cavity. Two driven wheels 15 are rotatably connected to a mounting plate 19 fixed to the inner top wall of the first housing 1, and the two driven wheels 15 are arranged sequentially along the length of the cable. The split housing structure facilitates the installation and maintenance of internal components, and the sequential arrangement of the two driven wheels 15 ensures a stable contact area with the cable, improving the stability of movement.

[0023] In one alternative, a sliding plate 16 is vertically slidably connected inside the first housing 1, and an elastic traction assembly is provided between the sliding plate 16 and the first housing 1. The driving wheel 14 is rotatably connected to one side of the sliding plate 16 and located below the two driven wheels 15. The first power mechanism is installed on the sliding plate 16 and is connected to the driving wheel 14 for transmission. The elastic traction assembly causes the driving wheel 14 and the driven wheels 15 to clamp the cable.

[0024] The sliding plate 16 is vertically slidably connected inside the first housing 1. The driving wheel 14 is rotatably connected to one side of the sliding plate 16 and located below the two driven wheels 15. The first power mechanism is installed on the sliding plate 16 and is connected to the driving wheel 14 for transmission. The elastic traction component keeps the driving wheel 14 and the driven wheel 15 in a state of clamping the cable.

[0025] The sliding plate 16, in conjunction with the elastic traction component, enables the floating adjustment of the drive wheel 14, which can automatically adapt to cables of different diameters and maintain a constant clamping force to prevent slippage or excessive tightness that could damage the cable.

[0026] In one alternative embodiment, the first power mechanism includes a second drive member 17 fixedly mounted on a sliding plate 16. The output end of the second drive member 17 is connected to a reducer 18, which is fixedly mounted on the sliding plate 16. The output end of the reducer 18 is connected to the drive wheel 14. The second drive member 17 drives the drive wheel 14 to rotate through the reducer 18, thereby moving the power box along the cable.

[0027] The second drive unit 17 is fixedly mounted on the sliding plate 16, and its output end is connected to the reducer 18. The reducer 18 is fixedly mounted on the sliding plate 16, and its output end is connected to the drive wheel 14. The second drive unit 17 drives the drive wheel 14 to rotate through the reducer 18, thereby driving the power box to move along the cable.

[0028] The reducer 18 can increase the output torque, enabling the robot to have sufficient climbing drive force on steep cables, while reducing the motor speed requirement and improving control accuracy.

[0029] In one alternative, a movable handle 13 is fixedly connected to the bottom end of the sliding plate 16. The movable handle 13 extends through the bottom surface of the first housing 1. A fixed handle 12 is fixedly connected between the bottom ends of the first housing 1 and the second housing 2. The fixed handle 12 and the movable handle 13 are correspondingly arranged. By gripping the fixed handle 12 and the movable handle 13, the distance between the driving wheel 14 and the driven wheel 15 is increased, which facilitates the cable entering between the driving wheel 14 and the driven wheel 15.

[0030] The movable handle 13, which is fixed to the bottom end of the sliding plate 16, extends out of the bottom surface of the first housing 1. A fixed handle 12 is fixed between the bottom ends of the first housing 1 and the second housing 2. The fixed handle 12 and the movable handle 13 are correspondingly arranged. When both are gripped tightly, the distance between the driving wheel 14 and the driven wheel 15 increases, which facilitates the entry of the cable.

[0031] This grip design allows for easy unlocking of the clamping gap with a single hand, significantly simplifying the on-site mounting process and enabling a single person to complete the cable insertion operation, thus improving deployment efficiency.

[0032] In one alternative, the fixed plate 3 is fixed to the second housing 2, and an annular cavity for the movement of the detection mechanism is circumferentially opened on the side of the fixed plate 3 away from the second housing 2. The annular cavity is coaxially arranged with the cable, and the second power mechanism is arranged in the annular cavity.

[0033] The fixed plate 3 is fixed to the second housing 2, and an annular cavity coaxial with the cable is formed on the side of the fixed plate away from the second housing 2. The second power mechanism is set in the annular cavity to allow the detection mechanism to move. The annular cavity structure provides a stable annular motion track for the detection mechanism, ensuring that the rotational movement of the detection mechanism around the cable axis is accurate and smooth.

[0034] In one alternative embodiment, the second power mechanism includes a drive assembly and a moving assembly mounted on the mounting bracket 6; The movable component includes at least two pulleys 9, which are rotatably connected to the mounting frame 6 and rollably connected to the slide rail 5, which is circumferentially opened at the inner edge of the annular cavity.

[0035] The second power mechanism includes a drive assembly and a moving assembly mounted on the mounting bracket 6. The moving assembly includes at least two pulleys 9 rotatably connected to the mounting bracket 6, and the pulleys 9 are rolled within a slide rail 5 circumferentially opened at the inner edge of the annular cavity. The cooperation between the pulleys 9 and the slide rail 5 reduces rotational friction resistance, making the rotation of the detection mechanism smoother and reducing the energy consumption of the second power mechanism.

[0036] In one alternative embodiment, the drive assembly includes a first drive member 8 fixedly mounted on a mounting bracket 6. The first drive member 8 is drivenly connected to a gear 7, which is rotatably connected to the mounting bracket 6. The gear 7 meshes with a gear ring 4, which is circumferentially formed at the outer edge of an annular cavity.

[0037] The drive assembly includes a first drive member 8 fixedly mounted on the mounting bracket 6. The first drive member 8 is connected to a gear 7, which is rotatably connected to the mounting bracket 6 and meshes with a toothed ring 4 circumferentially opened at the outer edge of the annular cavity. The meshing transmission between the gear 7 and the toothed ring 4 enables precise control of the rotation angle, allowing the detection mechanism to stably stop at any desired angle for fixed-point detection.

[0038] In one alternative embodiment, the testing mechanism includes a mounting block 11, which is fixedly mounted on a mounting frame 6. A camera element 10 is fixedly mounted on the mounting block 11, with the camera end of the camera element 10 facing the cable.

[0039] Mounting block 11 is fixedly mounted on mounting frame 6, and imaging element 10 is fixedly mounted on mounting block 11 with the imaging end of imaging element 10 facing the cable. Imaging element 10 rotates around the cable with mounting frame 6 to achieve full-circumference image acquisition of the cable, eliminating blind spots in inspection and improving the fault detection rate.

[0040] During operation, first, grip the fixed handle 12 and the movable handle 13. The movable handle 13 causes the sliding plate 16 to slide downwards within the first housing 1, increasing the distance between the driving wheel 14, which is rotatably connected to one side of the sliding plate 16, and the two driven wheels 15, which are rotatably connected to the mounting plate 19. Insert the cable through the first opening and through the power box, positioning the cable between the driving wheel 14 and the two driven wheels 15. After releasing the fixed handle 12 and the movable handle 13, the elastic traction assembly causes the sliding plate 16 to return to its original position, clamping the cable between the driving wheel 14 and the two driven wheels 15. Then, activate the second drive unit 17. The second drive unit 17 drives the driving wheel 14 to rotate via the reducer 18. The friction between the driving wheel 14 and the cable causes the power box to move along the cable. At the same time, the first driving component 8 is activated, which drives the gear 7 to rotate. The gear 7 meshes with the toothed ring 4 at the outer edge of the annular cavity on the fixed disk 3, causing the mounting frame 6 to roll along the slide 5 at the inner edge of the annular cavity via the pulley 9. This causes the mounting block 11 and the imaging component 10 fixedly mounted on the mounting frame 6 to rotate around the cable axis. The imaging end of the imaging component 10 always faces the cable for multi-angle detection.

[0041] By gripping the fixed handle 12 and the movable handle 13, the distance between the drive wheel 14 and the two driven wheels 15 is increased. Releasing the grip causes the sliding plate 16 to automatically reset, enabling a single person to quickly insert and clamp the cable, significantly simplifying the on-site mounting process. The drive wheel 14 and the two driven wheels 15 form a three-point radial constraint on the cable. Combined with the constant clamping force provided by the elastic traction component, it can automatically adapt to cables of different diameters, physically preventing the robot from derailing during movement. The second drive unit 17 drives the drive wheel 14 to rotate via the reducer 18, increasing the robot's climbing drive force on steep cables. The first drive unit 8, through the meshing of the gear 7 and the gear ring 4, drives the mounting frame 6 and the imaging component 10 to rotate precisely around the cable axis, achieving full-circumferential image acquisition of the cable and eliminating blind spots during inspection. The power box is made of ASA, PLA, or ABS material, significantly reducing the overall weight and allowing the equipment to be carried and deployed quickly by a single person.
