Description

A live-line device for ultra-high voltage composite crossarm tower Technical Field

[0001] This invention relates to the field of live-line working technology for crossarm towers, and in particular to a live-line outgoing device for ultra-high voltage composite crossarm towers. Background Technology

[0002] With the rapid development of my country's economy and society and the continuous optimization of its energy structure, electricity demand continues to grow, and the scale of power grid construction continues to expand. As an important component of the national backbone power grid, ultra-high voltage transmission lines play an irreplaceable role in long-distance, large-capacity power transmission. In recent years, with the continuous advancement of ultra-high voltage AC / DC transmission projects, the voltage level of ultra-high voltage transmission lines has been continuously improved, the line structure has become increasingly complex, and the operating environment has become more diverse, which has put forward higher requirements for the safe and stable operation of the power grid. In order to ensure the continuity of the power grid and the reliability of power supply, live-line working technology, as an important means to achieve tasks such as line maintenance, equipment replacement, and fault handling, is receiving increasing attention from the power industry. Compared with traditional power outage working methods, live-line working can effectively avoid economic losses and social impacts caused by line outages, and significantly improve the efficiency of power grid operation and maintenance and the quality of power supply services.

[0003] However, traditional crossarm towers have many technical bottlenecks and safety hazards during live-line work. With the continuous development of composite material technology, structural optimization design and intelligent operation equipment, composite crossarm towers, as a new type of tower structure, have been gradually promoted and applied in some newly built transmission lines due to their advantages such as light weight, good insulation performance and strong corrosion resistance.

[0004] Existing live-line outgoing devices for ultra-high voltage composite crossarm towers lack adequate supporting equipment for live-line work, especially in live-line outgoing operations, which rely on manual high-altitude work. However, the working space is very limited, making it difficult for workers to complete complex operations within a safe distance. High-altitude operations are mostly carried out by a single person, resulting in high work intensity, low work efficiency, and increased work difficulty and safety risks. Based on this, we propose a live-line outgoing device for ultra-high voltage composite crossarm towers to solve the above problems. Summary of the Invention

[0005] Therefore, there is an urgent need to develop a new type of live-line outgoing device suitable for ultra-high voltage composite crossarm towers to address the shortcomings of traditional structures in terms of working space, safety distance, and ease of operation. This device should have good insulation performance, stable mechanical support capacity, flexible work platform adjustment function, and be compatible with existing live-line working tools and procedures, thereby enabling safe, efficient, and standardized live-line work and comprehensively improving the operation and maintenance level and intelligence of ultra-high voltage transmission lines.

[0006] The technical solution of this invention is as follows: a live-line device for an ultra-high voltage composite crossarm tower, comprising a platform frame and a main support arm installed at the lower end of the platform frame, wherein a connecting base is provided at the end of the platform frame for connecting to the top or side of the crossarm tower, and a working platform is installed at the upper end of the platform frame (a shielding electrode mesh is set at the bottom of the working platform and connected to the conductor through an equipotential rod to achieve the same potential between the platform and the conductor, preventing induced electric shock; however, the shielding electrode mesh is a conventional means to prevent workers from being easily electrocuted in ultra-high voltage environments where the induced voltage is high; therefore, this application does not describe the shielding electrode mesh). (Detailed explanation follows) A safety railing is provided on the side of the upper surface of the work platform, and a docking component is provided on the side of the platform frame surface. A sliding seat is provided on the inner side of the platform frame. The sliding seat and the platform frame are movably connected by a sliding telescopic component. The sliding telescopic component is used to adjust the position of the work platform along the axis of the crossbeam. A direction adjustment component is provided between the upper end of the sliding seat and the lower end of the work platform. The direction adjustment component is used to change the angle of the work platform and adapt to the angle of the crossbeam. An adjustable connector is provided on the side of the upper end of the platform frame. The adjustable connector connects the platform frame and the crossbeam.

[0007] It should be noted that the work platform is an integrated structure that can be equipped with conventional remote control and safety monitoring systems. That is, the remote control system, including a remote controller and a PLC control module, is integrated into the device, and an electric field strength sensor, a grounding status detection module, and a platform tilt angle sensor are added to the platform. Additionally, a video monitoring camera can be optionally installed to visualize the work process. The detection structures mentioned above are all existing conventional methods.

[0008] Furthermore, the connecting base includes mounting seats rotatably mounted on both sides of the end of the platform frame. Bolt holes are provided on both sides of the surface of the mounting seats, and the mounting seats are connected to the crossbeam tower by bolts.

[0009] Furthermore, the surface of the work platform is equipped with rubber anti-slip mats, and four safety railings are installed on the four sides of the work platform. The safety railings are insulated railings, and the bottom of the safety railings is rotatably connected to the work platform.

[0010] It should be noted that the rotating connection of the safety fence is foldable and uses an elastic buffer structure to achieve limit, making it easy to store and prevent impact.

[0011] Furthermore, the docking components include a grounding wire interface, a boom truck interface, and a lifting ring, all located on the surface of the work platform. The grounding wire interface is used to connect the grounding wire, the boom truck interface is a hydraulic interface used to connect aerial work tools, and the lifting ring is used to connect the lifting equipment.

[0012] Furthermore, the sliding telescopic assembly includes a threaded rod rotatably connected to the inside of the platform frame and a guide rod fixedly installed on the inside of the platform frame, and a servo motor fixedly installed on the surface of the platform frame.

When the threaded rod rotates, it drives the sliding seat to move left or right along the guide rod.

[0013] Furthermore, the direction adjustment assembly includes a connecting shaft rotatably mounted on the upper end of the sliding seat and a rotary motor fixedly mounted on the sliding seat. The upper end of the connecting shaft is fixedly connected to the lower end of the work platform, and the output end of the rotary motor is connected to the connecting shaft through a transmission assembly. The rotary motor is used to drive the connecting shaft to rotate, which can drive the work platform to rotate horizontally.

[0014] Furthermore, the transmission assembly includes a first gear fixedly mounted on the connecting shaft and a second gear fixedly mounted on the output end of the rotary motor. The first gear and the second gear are meshed together, and when the second gear rotates, power is transmitted to the connecting shaft through the meshing of the gears.

[0015] Furthermore, the adjustable connectors are symmetrically installed on both sides of the platform frame. The adjustable connectors include a first connector that is rotatably installed on the surface of the platform frame, a second connector that is rotatably connected to the upper end of the first connector, and an adjusting screw that is fixedly connected to the upper end of the second connector. The adjustable connectors also include a snap-fit ​​seat installed on the crossbeam, a third connector that is rotatably installed on one side of the snap-fit ​​seat, and an identical adjusting screw that is fixedly connected to the third connector.

[0016] Furthermore, one end of each of the two adjusting screws is threaded to both ends of the outer sleeve. The surface of the outer sleeve is provided with an anti-slip structure. When the outer sleeve is rotated, one end of each of the two adjusting screws moves within the outer sleeve, adjusting the length of the adjusting screws and the outer sleeve.

[0017] The beneficial effects of the present invention are as follows: 1. The ultra-high voltage composite crossarm tower energized outgoing line device, through the connection between the main support arm and the tower body, builds the working platform under the crossarm, which facilitates personnel to carry out outgoing operations on the platform, realizes multi-person collaborative operation, improves work efficiency, and ensures safety.

[0023] With the rapid development of my country's economy and society and the continuous optimization of its energy structure, the power grid, as a crucial carrier of national energy security and energy transition, is facing unprecedented opportunities and challenges. Currently, the power system is evolving from a traditional "centralized and rigid" model to a "cleaner, smarter, and more flexible" one. In this process, the safe and stable operation of transmission lines, as the "main artery" of power transmission, is of paramount importance.

[0024] In actual operation, traditional steel crossarm towers have gradually revealed shortcomings such as high maintenance costs, numerous safety hazards, and poor adaptability due to their large weight, susceptibility to corrosion, and poor insulation performance. In particular, during live-line work, traditional structures suffer from limited working space, uneven electric field distribution, and high risks to personnel, which seriously restricts the intelligent and efficient operation and maintenance of transmission lines.

[0025] Meanwhile, with the continuous advancement of ultra-high voltage and extra-high voltage power transmission projects, the voltage levels of transmission lines are constantly increasing, placing higher demands on the insulation performance, structural strength, and operational stability of transmission equipment. Furthermore, rapid urbanization is leading to increasingly strained transmission line corridor resources, posing challenges to traditional metal tower structures in terms of space utilization and environmental harmony.

[0026] Against this backdrop, the use of new composite materials to manufacture crossarm towers, combined with advanced live-line technology, has become a key breakthrough in improving the safety, economy, and intelligence of transmission lines. Composite material crossarm towers have advantages such as light weight, high strength, corrosion resistance, and excellent insulation performance, making them particularly suitable for complex operating environments such as high voltage, high humidity, and high corrosiveness. Live-line technology, on the other hand, enables maintenance, capacity expansion, and other operations on the line without interrupting power supply, significantly improving power supply continuity and operation and maintenance efficiency.

[0027] Therefore, developing a energized outgoing line device for composite crossarm towers suitable for ultra-high voltage transmission lines not only meets the strategic needs of high-quality development of the power grid, but is also an important measure to achieve the green and intelligent upgrading of transmission lines.

[0028] In recent years, composite materials have been increasingly widely used in power equipment. Carbon fiber reinforced polymer (CFRP) and glass fiber reinforced polymer (GFRP) are widely used in power facilities such as insulators, poles, and crossarms due to their excellent mechanical and insulation properties. At the same time, with the development of intelligent technology, more and more intelligent sensing, remote control, and robotics technologies are being used in power operations. However, manual operation is still indispensable in high-altitude live-line work.

[0029] Meanwhile, the State Grid Corporation of China also emphasized the need to strengthen research on key core technologies and promote the lightweight, intelligent, and green upgrading of power transmission equipment. The development of energized outgoing line devices for composite crossarm towers aligns with national and industry policy guidelines and enjoys a favorable policy support environment. From an economic perspective, the application of energized outgoing line devices for composite crossarm towers can bring multiple benefits: reduced operation and maintenance costs: composite materials are corrosion-resistant and have a long lifespan, reducing the regular anti-corrosion maintenance costs of traditional metal towers; improved operational efficiency: energized outgoing line devices enable uninterrupted operation, avoiding economic losses caused by power outages; improved power supply reliability: reduced line outage time, ensuring continuous power supply to users and improving the quality of power services; and saving land resources: the compact structure of composite crossarm towers helps optimize line corridor layout and adapt to the needs of urbanization.

[0030] In summary, the development of energized outgoing line devices for ultra-high voltage composite crossarm towers is an important practice in response to the national energy strategy and in promoting the intelligent development of the power grid. This project is based on the actual problems in the current operation of the power grid, integrates new materials, new technologies, and new concepts, and has distinct technological advancements and market foresight.

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] Please refer to Figures 1-8. This invention provides an embodiment: a live-line device for an ultra-high voltage composite crossarm tower, comprising a platform frame 1 and a main support arm 2 installed at the lower end of the platform frame 1. A connecting base is provided at the end of the platform frame 1 for connecting to the top or side of the crossarm tower. A working platform 3 is installed at the upper end of the platform frame 1. A safety railing 4 is provided on the side of the upper surface of the working platform 3. A docking assembly is provided on the side of the surface of the platform frame 1. A sliding seat 6 is provided on the inner side of the platform frame 1, and the sliding seat 6 and the platform frame 1 are connected by a sliding... The movable telescopic component is used to adjust the position of the work platform 3 along the axis of the crossarm. A direction adjustment component is provided between the upper end of the sliding seat 6 and the lower end of the work platform 3. The direction adjustment component is used to change the angle of the work platform 3 and adapt to the angle of the crossarm. An adjustable connector is provided on the side of the upper end of the platform frame 1. The adjustable connector connects the platform frame 1 and the crossarm. The work platform 3 is built on the crossarm tower through the main support arm 2 and the adjustable connector, so that personnel can perform line-going operations on the work platform 3, which improves safety.

[0033] The connecting base includes mounting seats 101 rotatably mounted on both sides of the end of the platform frame 1. Bolt holes are provided on both sides of the surface of the mounting seat 101, and the mounting seat 101 is connected to the crossbeam tower by bolts.

[0034] It should be noted that the rotating connection between the mounting base 101 and the platform frame 1 adopts a damped bearing structure, which can realize the adjustment of the moving pitch angle and adapt to the mounting surface with different tilt angles on the top or side of the crossarm tower. The bolt holes can adopt a waist-shaped hole design, allowing for ±5mm error compensation in the installation position, which facilitates quick alignment and installation on site.

[0035] In this embodiment, the surface of the work platform 3 is provided with a rubber anti-slip pad, and four safety railings 4 are provided on the four sides of the work platform 3. The safety railings 4 are insulated railings, and the bottom of the safety railings 4 is rotatably connected to the work platform 3.

[0036] It should be noted that the safety fence 4 is made of epoxy resin insulation material. The bottom of the fence is connected to the work platform 3 by hinges. After unfolding, it is fixed by pins. The rubber anti-slip pads prevent workers from slipping.

[0037] Please refer to Figures 2, 4 and 5. In this embodiment, the docking assembly includes a grounding wire interface 301, a boom truck interface 302 and a lifting ring 303 disposed on the surface of the work platform 3. The grounding wire interface 301 is used to connect the grounding wire, the boom truck interface 302 is a hydraulic interface and is used to connect aerial work tools, and the lifting ring 303 is used to connect the lifting device.

[0038] It should be noted that the grounding wire interface 301 is a plug-in interface, which facilitates the quick installation of the grounding wire. The boom truck interface 302 is compatible with the hydraulic tools of mainstream aerial work platforms. The lifting ring 303 is forged from No. 45 steel to meet the overall lifting requirements of the device.

[0039] Please refer to Figures 1, 2, and 3. In this embodiment, the sliding telescopic assembly includes a threaded rod 601 rotatably connected to the inner side of the platform frame 1, a guide rod 602 fixedly installed on the inner side of the platform frame 1, and a servo motor 603 fixedly installed on the surface of the platform frame 1. One end of the threaded rod 601 is threadedly connected to the sliding seat 6, and the guide rod 602 is slidably connected to the sliding seat 6. The output end of the servo motor 603 is fixedly connected to the threaded rod 601. The servo motor 603 is used to drive the threaded rod 601 to rotate. When the threaded rod 601 rotates, it drives the sliding seat 6 to move left or right along the guide rod 602.

[0040] It should be noted that the forward and reverse rotation of the threaded rod 601 is controlled by the servo motor 603, thereby driving the sliding seat 6 to move and adjusting the position of the work platform 3. The servo motor 603 is a permanent magnet synchronous motor with an encoder and a reducer is added to drive it, which ensures the position control accuracy. The control of the servo motor 603 is a conventional technical means.

[0041] In practical applications, a rotating handwheel can replace the servo motor 603, allowing the sliding telescopic component to be manually adjusted. Specifically, a rotating handwheel with anti-slip texture is added to the end of the threaded rod 601. The handwheel and the threaded rod 601 are connected by a flat key and secured with a locking nut. During adjustment, the operator rotates the handwheel to drive the threaded rod 601 to rotate, which in turn moves the sliding seat 6 along the guide rod 602. The trapezoidal thread of the threaded rod 601 enables a self-locking function, maintaining the adjusted position without the need for an additional braking device. This is suitable for small-scale operation scenarios.

[0042] Please refer to Figures 3, 4, and 5. In this embodiment, the direction adjustment assembly includes a connecting shaft 604 rotatably mounted on the upper end of the sliding seat 6 and a rotary motor 605 fixedly mounted on the sliding seat 6. The upper end of the connecting shaft 604 is fixedly connected to the lower end of the work platform 3, and the output end of the rotary motor 605 is connected to the connecting shaft 604 via a transmission assembly. The rotary motor 605 is used to drive the connecting shaft 604 to rotate, which can drive the work platform 3 to rotate horizontally. The transmission assembly includes a first gear 606 fixedly mounted on the connecting shaft 604 and a second gear 607 fixedly mounted on the output end of the rotary motor 605. The first gear 606 and the second gear 607 are meshed. When the second gear 607 rotates, the power is transmitted to the connecting shaft 604 through the meshing of the gears.

[0043] It should be noted that the rotation of the gear driven by the rotary motor 605 enables the connecting shaft 604 to drive the working platform 3 to turn horizontally. The rotary motor 605 is a stepper motor with a brake, which, together with the limit switch, achieves 0° / 45° mechanical positioning to ensure that the working platform 3 and the crossbeam angle are accurately matched.

[0044] Please refer to Figures 6, 7, and 8. In this embodiment, adjustable connectors are symmetrically installed on both sides of the platform frame 1. The adjustable connectors include a first connector 701 rotatably installed on the surface of the platform frame 1, a second connector 702 rotatably connected to the upper end of the first connector 701, and an adjusting screw 703 fixedly connected to the upper end of the second connector 702. The adjustable connectors also include a snap-fit ​​seat 704 installed on the crossbeam, a third connector 705 rotatably installed on one side of the snap-fit ​​seat 704, and the same adjusting screw 703 fixedly connected to the third connector 705. One end of each of the two adjusting screws 703 is threadedly connected to both ends of an outer sleeve 706. The surface of the outer sleeve 706 is provided with an anti-slip structure (not shown in the figure). When the outer sleeve 706 is rotated, one end of each of the two adjusting screws 703 moves within the outer sleeve 706, adjusting the length of the adjusting screws 703 and the outer sleeve 706.

[0045] It should be noted that the length of the adjustable connector can be adjusted by rotating the outer sleeve 706, which not only facilitates the adaptation to different crossbeam structures, but also changes the tilt angle of the platform frame 1. The inner wall of the outer sleeve 706 is provided with left-hand / right-hand threaded sections, and quick adjustment can be achieved by manual rotation through anti-slip knurling (knurling module 0.8). With the dual-axis rotation of connector 1 701 and connector 2 702, installation errors can be eliminated.

[0046] Working principle: During installation, the device is fixed to the crossarm tower bolts via the mounting base 101 of the connecting base. The locking seats 704 of the adjustable connectors on both sides engage the crossarm. The length of the adjusting screw 703 is adjusted by rotating the outer sleeve 706. This, combined with the dual-axis rotation of connecting seat one 701 and connecting seat two 702, eliminates installation errors and achieves horizontal fixation of the platform frame 1. Before operation, the safety fence 4 is deployed for protection, rubber anti-slip mats prevent personnel from slipping, the grounding wire interface 301 is connected to the grounding wire to achieve potential balance, and the boom truck interface 302 is connected to the hydraulic tools. After starting the equipment, the servo... Motor 603 drives threaded rod 601 to rotate, causing sliding seat 6 to move along guide rod 602, thereby adjusting work platform 3 along crossarm axis. Rotary motor 605 drives connecting shaft 604 through gear 1 606 and gear 2 607 to rotate work platform 3 horizontally, ensuring that workers are aligned with the exit position within a safe distance. After the operation is completed, reverse adjustment of sliding telescopic component and direction adjustment component resets the position, and folding safety fence 4 allows for storage. The work platform 3 facilitates live wire operation and ensures safety.

[0047] It should be noted that the control method of the present invention is controlled by a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail. At the same time, the control of the heat dissipation structure is adjusted according to the temperature.

[0048] The above are merely preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be considered as limitations on the present invention, and the scope of protection of the present invention should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
