Description

Technical Field

[0001] This invention relates to the field of power grid maintenance technology, specifically to a power grid operation safety enhancement device based on full-domain status linkage perception. Background Technology

[0002] In modern power systems, power grid towers are the "steel backbone" supporting the power transmission network. As a core infrastructure ensuring stable energy transmission, their role is indispensable. However, due to long-term outdoor environmental erosion and natural aging, towers are prone to structural hazards. Therefore, maintenance personnel need to use professional testing equipment to conduct regular comprehensive inspections and condition assessments to provide accurate data for subsequent maintenance and repairs, ensuring the overall safe operation of the power grid. The full-domain status linkage sensing technology adopts a dual-core architecture of "multi-dimensional mechanical protection + intelligent IoT control." The system integrates three major modules: an intelligent displacement drive unit, an intelligent IoT operation platform, and a composite insulation load-bearing and material (personnel) transportation system. It innovatively integrates core technologies such as intelligent chip networking, dynamic load balancing, and three-dimensional attitude stabilization, improving the possibility, safety, and efficiency of working in harsh environments. It eliminates the dangers of high-altitude operations from the source, making power grid operations faster, safer, and more convenient. Based on the above, the use of power grid operation safety lifting devices helps improve the safety of operators and the efficiency of power grid operations. However, existing power grid operation safety lifting devices have the following shortcomings in actual use:

[0003] When the equipment lifts and lowers workers along the traction rope, the rope can only be wound on one side of the reel. This easily causes the equipment's center of gravity to shift towards the winding side. Furthermore, when workers sit on the equipment (with their weight added), the weight on one side increases further, causing the entire equipment and workers to tilt to one side, potentially leading to a fall. Simultaneously, workers sitting on the equipment must continuously exert force to adjust their posture to maintain balance, making it difficult to concentrate on maintenance work. Prolonged imbalance can also lead to exhaustion, accidental contact with live parts, or falling tools, increasing the risk of electric shock or being struck by objects. Moreover, the equipment lacks a function to dynamically adjust based on worker weight, resulting in the contact area and friction between the traction rope and the reel not being suitable for different weights. For heavier workers, excessive contact area and friction can cause the rope to jam, resulting in sudden jerks in lifting and lowering operations and exacerbating imbalance. For lighter workers, insufficient contact area and friction can lead to delayed braking response, further increasing the risk of fall. This mismatch in friction parameters also accelerates localized wear on the traction rope and reel, shortening the equipment's lifespan.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0005] The purpose of this invention is to provide a power grid operation safety enhancement device based on full-domain state linkage perception to solve the problems mentioned in the background.

[0009] Preferably, the inner side of the winding wheel is fixedly connected to the top of the slider, and the inner side of the winding wheel is connected to the outer side of the rotating rod by ball bearings. Limit blocks are fixed at equal angles at both ends of the winding wheel, and the end of the limit block away from the winding wheel is slidably connected to the side of the limit plate.

[0010] Preferably, the driving gear meshes with the pinion, and the pinion meshes with the large gear, and both limiting discs are threadedly connected to the lead screw.

[0011] Preferably, the friction adjustment assembly includes a cam, which is rotatably connected to the inside of the climber via a shaft. A movable block is connected to the inside of the climber below the cam, and the movable block is connected to the cam via a first connecting plate. An adjusting wheel is provided inside the climber below the movable block, and a contact block is fixed to the side of the adjusting wheel. A third spring is installed between the side of the bottom protrusion of the contact block and the inner wall of the climber.

[0012] Preferably, the movable block is slidably disposed inside the climber, and both ends of the first connecting plate are hinged to the top of the movable block and the side of the cam, respectively. The adjusting wheel is slidably disposed inside the climber.

[0013] Preferably, the movable block and the bonding block are positioned correspondingly, and the side of the bonding block away from the adjusting wheel and the bottom of the movable block are both inclined, and the inclined surfaces of the bonding block and the movable block are in contact.

[0014] Preferably, a guide plate is slidably connected inside the rotating rod, and a first spring is installed between the rear end of the guide plate and the inner wall of the rotating rod. A connecting plate is symmetrically arranged inside the rotating rod about the center point of the guide plate, and a friction block is installed on the side of one end of the connecting plate, and a wedge block is fixed on the side of the other end of the connecting plate. A second spring is installed between the opposite sides of the two connecting plates and the inner wall of the rotating rod. A linkage plate is hinged inside the climber at the front end of the rotating rod, and the upper side of the linkage plate is hinged to the front of the movable block through a second connecting plate.

[0015] Preferably, the end of the guide plate away from the first spring extends out of the front end of the rotating rod, and the extended end of the guide plate is semi-circular in shape. The connecting plate is in an inverted "L" shape and is slidably disposed inside the rotating rod.

[0016] Preferably, the opposing surfaces of the two friction blocks are in contact with the outer side of the slider, the opposing surfaces of the two wedge blocks and the guide plate are inclined, and the guide plate is in contact with the inclined surfaces of the two wedge blocks.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention, when the rotating rod is driven by a motor to rotate, on the one hand, drives the winding wheel to rotate synchronously between the two limiting discs, realizing stable winding of the traction rope and driving the equipment and operators to rise smoothly. On the other hand, the gear transmission drives the lead screw to rotate, causing the two limiting discs to move symmetrically along the axis of the rotating rod, and through the limiting block, drives the winding wheel to move synchronously, so that the traction rope is evenly distributed on the entire surface of the winding wheel, solving the problem of center of gravity shift caused by traditional single-sided winding, thereby realizing stable winding and even distribution of the traction rope, effectively ensuring the overall stability of the equipment when carrying personnel.

[0019] 2. In this invention, when workers of different weights sit on the support base, their weight causes the traction rope to taut and pushes the cam to rotate clockwise. This, via the first connecting plate, causes the movable block to move downwards, squeezing the contact block and causing the adjusting wheel to move away from the winding wheel. This changes the contact state between the traction rope and the winding wheel. The greater the weight, the greater the rotation angle of the cam, the downward distance of the movable block, and the pushing amplitude of the adjusting wheel. The more significant the adjustment of the contact parameters (such as contact area and pressure) between the traction rope and the winding wheel, the more effectively the friction force is matched. Thus, the friction force between the traction rope and the winding wheel can be automatically matched according to the weight of the worker, improving the adaptability and safety of use.

[0020] 3. In this invention, when the movable block moves downward, the second connecting plate drives the linkage plate to rotate around the fixed axis. By leveraging the principle, the guide plate is pushed to move horizontally, squeezing the two wedge blocks to separate. The wedge blocks drive the friction block to move through the connecting plate, reducing the contact pressure and friction between the friction block and the protrusion. This prevents the winding wheel from getting stuck when it moves due to the friction block "locking up" the slider. At the same time, the preset ball structure acts on the movement path of the winding wheel, further reducing the contact friction with other components when it moves axially. This ensures that the overall adjustment is smooth and efficient, thereby ensuring that the winding wheel moves synchronously and smoothly with the limit plate, ensuring that the traction rope is wound evenly, maintaining the stability of the equipment's center of gravity, and that the overall adjustment process is smooth and efficient.

Detailed Implementation

[0031] 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.

[0032] Please see Figures 1-9 This invention provides a technical solution: a power grid operation safety lifting device based on full-domain state linkage perception, including a climbing support plate 3, an auxiliary support plate 2 below the climbing support plate 3, a fixing plate between the auxiliary support plate 2 and the climbing support plate 3, a support base 1 on the front of the fixing plate, and a potential transfer rod 4 on the back of the fixing plate; it also includes a climber 5, which is fixedly installed on the upper surface of the climbing support plate 3 by bolts, a motor is installed on the back of the climber 5, and a rotating rod 6 is fixedly connected to the output end of the motor. Guide wheels 7 are installed in the upper and lower areas on the right side of the rotating rod 6 inside the climber 5. A sliding groove 12 is opened on the outer side of the rotating rod 6, and a slider 14 is slidably connected to the inner wall of the sliding groove 12.

[0033] In one embodiment of the present invention, the operator sits on the support base 1 and places both feet on the foot pedals of the auxiliary support plate 2. Simultaneously, the operator operates the climber 5 to leave the ground. After reaching the designated height, the operator requests permission from the work supervisor to enter the equipotential zone. Upon receiving permission, the operator uses the potential transfer rod 4 to perform the equipotential operation, maintaining a stable connection with the live conductor. The operator then adjusts the climber 5 to a suitable position, placing one foot on the auxiliary support plate 2 and the other foot on the support base 1. Using the panel, the operator climbs onto the conductor to perform the equipotential maintenance work. After the maintenance work is completed, the work supervisor checks and confirms the construction quality. The equipotential worker then adjusts the climber 5 to a suitable position and requests permission from the work supervisor to exit the equipotential zone. Upon receiving confirmation and permission from the work supervisor, the operator uses the potential transfer rod 4 to exit the equipotential zone, quickly disconnecting from the live conductor. Using the support base 1 and auxiliary support plate 2, the operator returns to the auxiliary device and operates the climber 5 back to the ground. During the descent, there should be no significant shaking, and the speed or range of motion should not be too fast or excessive.

[0034] A stabilizing traction assembly is provided on the outer side of the rotating rod 6. The stabilizing traction assembly includes a winding wheel 801, which is sleeved on the outer side of the rotating rod 6. A drive gear 804 is fixedly sleeved on the outer side of the rear end of the rotating rod 6. Inside the climber 5, a lead screw 803 is connected to the right bearing of the winding wheel 801, and a large gear 806 is fixedly sleeved on the outer side of the rear end of the lead screw 803. Inside the climber 5, a small gear 805 is rotatably connected between the drive gear 804 and the large gear 806. Both ends of the rotating rod 6 and the lead screw 803 are... A limiting disc 802 is fitted, the driving gear 804 meshes with the small gear 805, and the small gear 805 meshes with the large gear 806. Both limiting discs 802 and the lead screw 803 are threadedly connected. The inner side of the winding wheel 801 is fixedly connected to the top of the slider 14, and the inner side of the winding wheel 801 is rolledly connected to the outer side of the rotating rod 6 through the ball bearings 11. Limiting blocks 13 are fixed at equal angles at both ends of the winding wheel 801, and the end of the limiting block 13 away from the winding wheel 801 is slidably connected to the side of the limiting disc 802.

[0035] In one embodiment of the present invention, after the motor starts, it drives the rotating rod 6 to rotate. On the one hand, it drives the winding wheel 801 (limited by the limiting block 13) to rotate synchronously between the two limiting discs 802, so as to achieve stable winding of the traction rope and drive the equipment and the operator to rise smoothly. On the other hand, the rotating rod 6 drives the coaxial drive gear 804 to rotate synchronously. The drive gear 804 drives the small gear 805 to rotate through meshing transmission. The small gear 805 then drives the meshing large gear 806 to rotate, and finally drives the lead screw 803 to rotate synchronously. During the rotation of the lead screw 803, it drives the limiting discs 802 on both sides to move symmetrically along the axis of the rotating rod 6. The limiting discs 802, in turn, drive the winding wheel 801 to move synchronously through the limiting block 13, so that the traction rope can be evenly distributed on the entire wheel surface of the winding wheel 801 when winding, which completely avoids the problem of center of gravity shift caused by traditional single-sided winding and effectively ensures the overall stability of the equipment during personnel operation.

[0036] The climber 5 has an internal friction adjustment component, which includes a cam 901. The cam 901 is rotatably connected to the inside of the climber 5 via a shaft. A movable block 902 is connected to the inside of the climber 5 below the cam 901, and the movable block 902 is connected to the cam 901 via a first connecting plate 905. An adjusting wheel 903 is located inside the climber 5 below the movable block 902, and a contact block 904 is fixed to the side of the adjusting wheel 903. The side of the bottom protrusion of the contact block 904 is in contact with the climbing wheel. A third spring is installed between the inner walls of the device 5. The movable block 902 is slidably disposed inside the climber 5. The two ends of the first connecting plate 905 are hinged to the top of the movable block 902 and the side of the cam 901, respectively. The adjusting wheel 903 is slidably disposed inside the climber 5. The movable block 902 and the contact block 904 are positioned correspondingly. The side of the contact block 904 away from the adjusting wheel 903 and the bottom of the movable block 902 are both inclined. The contact block 904 is in contact with the inclined surface of the movable block 902.

[0037] In one embodiment of the present invention, when workers of different weights sit on the support base 1, their weight will cause the traction rope to naturally taut, thereby pushing the cam 901 to rotate clockwise. During the rotation of the cam 901, the first connecting plate 905 simultaneously drives the movable block 902 to move downward. The downward-moving movable block 902 will exert a squeezing force on the contact block 904. This squeezing force will cause the adjusting wheel 903 to move away from the winding wheel 801. The movement of the adjusting wheel 903 will simultaneously change the contact state between the traction rope and the winding wheel 801. At this time, the greater the weight of the worker, the greater the rotation angle of the cam 901, and the greater the downward distance of the movable block 902 and the pushing amplitude of the adjusting wheel 903. The adjusting wheel 903 moves away from the winding wheel 801. 1. This reduces the wrap angle between the traction rope and the winding wheel 801, thus reducing the friction between them. This allows for automatic adjustment of the friction between the traction rope and the winding wheel 801 based on the weight of the operator, preventing jamming and impact under heavy loads, improving equipment safety and service life, and enhancing the safety of lowering and retrieval to prevent excessive descent. After maintenance is completed, the equipment lowers the operator, who then dismounts. At this point, the traction rope is no longer taut, and the cam 901 rotates in the opposite direction to reset under the stored force of the torsion spring. The first connecting plate 905 drives the movable block 902 to reset upwards, preventing it from pressing against the contact block 904. The contact block 904 and the adjusting wheel 903 then reset under the elastic force of the third spring, facilitating future adjustments.

[0038] A guide plate 10 is slidably connected inside the rotating rod 6, and a first spring is installed between the rear end of the guide plate 10 and the inner wall of the rotating rod 6. Connecting plates 15 are symmetrically arranged inside the rotating rod 6 about the center point of the guide plate 10, and a friction block 17 is installed on the side of one end of the connecting plate 15, while a wedge block 16 is fixed to the side of the other end of the connecting plate 15. Second springs are installed between the opposite surfaces of the two connecting plates 15 and the inner wall of the rotating rod 6. A linkage plate 18 is hinged inside the climber 5 at the front end of the rotating rod 6, and the linkage plate 18... The upper side is hinged to the front of the movable block 902 via the second connecting plate 19. The end of the guide plate 10 away from the first spring extends out of the front end of the rotating rod 6, and the extended end of the guide plate 10 is set in a semi-circular shape. The connecting plate 15 is set in an inverted "L" shape, and the connecting plate 15 is slidably set inside the rotating rod 6. The opposite surfaces of the two friction blocks 17 are in contact with the outer side of the slider 14. The opposite surfaces of the two wedge blocks 16 and the guide plate 10 are both inclined, and the inclined surfaces of the guide plate 10 and the two wedge blocks 16 are in contact.

[0039] In one embodiment of the present invention, when the movable block 902 moves downward, the second connecting plate 19 drives the linkage plate 18 to rotate around the fixed axis. Using the lever principle, the rotating end of the linkage plate 18 pushes the guide plate 10 to move horizontally. The moving guide plate 10 exerts a squeezing force on the two wedge blocks 16, causing the two wedge blocks 16 to separate in opposite directions. The wedge blocks 16 synchronously drive the friction block 17 to move via the connecting plate 15, reducing the contact pressure between the friction block 17 and the slider 14, and consequently reducing the friction between them. This prevents the winding wheel 801 from getting stuck due to the friction block 17 "locking up" the protrusion during movement, ensuring that the winding wheel 801 can move synchronously and smoothly with the limiting plate 802. This ensures that the traction rope is wound evenly, maintaining the stability of the equipment's center of gravity from the source. At the same time, the pre-set ball bearing 11 structure can directly act on the movement path of the winding wheel 801, further reducing the contact friction between the winding wheel 801 and other components during axial movement, ensuring a smooth and efficient overall adjustment process. Then, when the operator leaves the equipment, the movable block 902 is reset under the action of the cam 901 and the torsion spring, and the linkage plate 18 is rotated and reset by the second connecting plate 19, so that it no longer pushes the guide plate 10. At this time, the guide plate 10 is reset under the elastic force of the first spring and no longer squeezes the two wedge blocks 16, so that the friction block 17, the connecting plate 15 and the wedge block 16 are reset under the elastic force of the second spring.

[0040] Working Principle: When using this power grid operation safety lifting device based on full-domain status linkage perception, the operator first sits on the support base 1 with their feet on the foot pedals of the auxiliary support plate 2. After the climber 5 is lifted off the ground, the motor drives the rotating rod 6 to rotate. On one hand, this drives the winding wheel 801 to wind the rope, enabling the equipment to lift the operator smoothly. On the other hand, through gear transmission, it drives the lead screw 803 to rotate, causing the limit plate 802 and the winding wheel 801 to move synchronously, ensuring that the traction rope is evenly wound to prevent the center of gravity from shifting. At the same time, the operator's weight tauts the traction rope, pushing the cam 901 to rotate. This rotation, via the first connecting plate 905 and the movable block 902, drives the adjusting wheel 903 to move, automatically adapting the traction rope to the winding wheel 801. The friction of the winding wheel 801 is adjusted more significantly by the greater the weight, and the movement of the movable block 902 will reduce the resistance of the friction block 17 by linking the lever and wedge block 16 when it moves down. The ball bearing 11 structure assists in reducing resistance, ensuring that the winding wheel 801 moves smoothly. After maintenance is completed, the equipment lowers with personnel. After the personnel leave, all parts are reset under the action of torsion springs and springs. When it rises to the designated height, the personnel apply for equipotential work. After permission is granted, the personnel operate the potential transfer rod 4 to adjust the climber 5 to the work position and climb the conductor for maintenance. After the maintenance is completed and the quality is confirmed, the personnel apply to exit the equipotential work, disconnect from the live body and return to the auxiliary device, and then operate the climber 5 to return to the ground. Large swaying and excessive speed are avoided when descending.
