Description

Technical Field

[0001] This invention belongs to the field of power transmission line operation and maintenance, and specifically relates to a device for assembling wiring for single conductors in power transmission lines during maintenance work. Background Technology

[0002] When carrying out construction and maintenance work on single conductors of transmission lines, workers have to climb up using traditional methods, either by holding onto something with their hands or feet, or by using rope ladders. However, when working on 500kV overhead ground lines, it is necessary to use ladders or heavy single-line trolleys. Regardless of the method used, the work is extremely physically demanding, and the workers are also greatly affected by the natural environment, such as wind, vibration, swaying, and overturning, which poses significant safety hazards to the workers. Therefore, there is an urgent need for a set of auxiliary tools for single-line maintenance work. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a simple, easy-to-use wiring assembly for transmission line maintenance work that eliminates the working hazards associated with single-conductor transmission line maintenance.

[0004] The technical solution adopted in this invention is: A wiring assembly for power transmission line maintenance includes a main wheel, two auxiliary wheels, a nut, two telescopic booms, and a platform. The main wheel and the two auxiliary wheels are arranged in an equilateral triangle, with the main wheel at the top. Two fixed connecting rods and two connecting rods are fixedly mounted on the axles on both sides of the main wheel. The lower ends of the two fixed connecting rods are fixedly mounted on the axles on one side of the two auxiliary wheels. The lower ends of the two connecting rods are connected to folding bushings with locking and unlocking functions via pins. A locking screw is provided on the connecting arm at the other end of the folding bushing, and the locking screw is threaded... A fixed nut with a handle is connected. The two connecting rods are fixedly mounted on the axles on the other side of the two auxiliary wheels through a folding bushing and a locking screw. The screw nut is horizontally arranged between the two auxiliary wheels. The two ends of the screw nut are respectively threaded to two lead screw shafts. The outer ends of the two lead screw shafts are respectively fixedly mounted on the axles on one side of the two auxiliary wheels. The upper ends of the two telescopic booms are respectively fixedly mounted on the lower ends of the boom frame. The upper ends of the boom frame are respectively mounted on the axles on both sides of the two auxiliary wheels. The lower ends of the two telescopic booms are respectively fixedly mounted on the two side walls of the platform.

[0005] The rear end of the locking screw is provided with a pin hole, and a positioning pin is fixedly installed laterally in the pin hole. The positioning pin is laterally locked between the handle of the fixing nut, which can restrict the rotation of the fixing nut.

[0006] The platform is composed of foldable slats connected by multiple pins, making it easy to fold and carry.

[0007] The main wheel, two auxiliary wheels, screw nut, two telescopic booms, and platform are all made of lightweight alloy materials.

[0008] The two telescopic booms are scissor-type telescopic booms, which can ensure both tensile strength and lateral stability, and have the advantage of being telescopic.

[0009] This invention features a triangular three-wheel clamping structure, which, compared to the traditional single-wheel method, offers greater stability and is less prone to disengagement. The three-wheel clamping structure allows for flexible tightening and loosening, enabling precise positioning and operation at any time, freeing up the hands. The telescopic boom is scissor-type, suitable for workers of different body types. This invention is easy to assemble and disassemble, and compared to traditional tools, it is easy to carry and install. During operation, it reduces the risks associated with single-line work, including maintenance, construction, and relocation, minimizing the risks of tilting, tipping, and slipping. This significantly improves worker safety and work efficiency. Attached Figure Description

Detailed Implementation

[0011] 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.

[0012] See Figures 1-2 A wiring assembly for power transmission line maintenance includes a main wheel 1, two auxiliary wheels 2, a nut 3, two telescopic booms 4, a platform 5, two fixed connecting rods 6, and two connecting rods 7. The main wheel 1, two auxiliary wheels 2, nut 3, two telescopic booms 4, platform 5, two fixed connecting rods 6, and two connecting rods 7 are all made of lightweight alloy materials.

[0013] The main wheel 1 and two auxiliary wheels 2 are arranged in an equilateral triangle, with the main wheel 1 at the top and the two auxiliary wheels 2 arranged parallel to each other below the main wheel 1. Each end of the two fixed connecting rods 6 has a shaft hole. The upper shaft holes of the two fixed connecting rods 6 are respectively fitted onto the axles on the front side of the main wheel 1 and fixed with nuts. The lower shaft holes of the two fixed connecting rods 6 are respectively fitted onto the axles on the front side of the two auxiliary wheels 2 and fixed with nuts.

[0014] See Figure 4 The upper ends of the two connecting rods 7 are provided with shaft holes, which are respectively fitted onto the axles on the rear side of the main wheel 1 and fixed by nuts. The lower ends of the two connecting rods 7 are respectively connected to folding bushings 8 with locking and unlocking functions via pins. A locking screw 9 is provided on the connecting arm at the other end of the folding bushing 8, and a fixing nut 14 with a handle is threaded onto the locking screw 9. The two connecting rods 7 are fixedly fitted onto the axles on the rear side of the two auxiliary wheels 2 via the folding bushings 8 and the locking screw 9. The rear end of the locking screw 9 is provided with a pin hole. After the fixing nut 14 is tightened, a positioning pin 15 is horizontally fixed in the pin hole. The positioning pin 15 is horizontally locked between the handles of the fixing nut 14, so that the fixing nut 14 is limited and cannot rotate, thus achieving a locking function.

[0015] The nut 3 is horizontally arranged between the two auxiliary wheels 2. Two lead screw shafts 10 are threaded to both ends of the nut 3. The outer ends of the two lead screw shafts 10 are respectively provided with shaft holes, and the shaft holes are respectively fitted onto the wheel axles on the front side of the two auxiliary wheels 2 and fixed by nuts.

[0016] See Figure 3 The two telescopic booms 4 are scissor-type telescopic booms. The upper ends of the two telescopic booms 4 are respectively pin-fixed to the lower ends of the two boom frames 11. The upper ends of the two boom frames 11 are respectively provided with bushings, which are respectively fitted onto the axles on both sides of the two auxiliary wheels 2 and fixed by nuts. The lower ends of the two telescopic booms 4 are respectively fixed to the side walls of the platform 5. The platform 5 is a foldable platform, which is composed of foldable strips connected by multiple pins 16.

[0017] In use, the main wheel 1 and the two auxiliary wheels 2 are made of alloy material with 20-30mm grooves, and adopt a three-wheel equilateral triangle design. The three wheels are connected in a triangular arrangement, with one side fixed and the other unlocked. This structure allows the single conductor 12 to be smoothly embedded into the three wheels. The main wheel 1 is positioned above the single conductor 12, and the two auxiliary wheels 2 are positioned below the single conductor 12, ensuring that the single conductor 12 cannot fall off in the middle of the three wheels. At the same time, the nut 3 between the two auxiliary wheels 2 increases the height of the three-wheel triangle when the nut 3 is tightened, thereby reducing conductor resistance. Conversely, when the nut 3 is loosened, the height of the three-wheel triangle decreases, thus clamping the single conductor. This design makes the ladder frame device move more smoothly during single-line travel and achieves the effect of clamping and fixing at a fixed point for operation. At the same time, the construction workers unfold the telescopic boom 4 and the sitting platform 5. After the workers fasten their five-point safety belts, they can sit on the cable routing device to carry out the work. This single conductor 12 maintenance cable routing combination device will greatly reduce the center of gravity of the human body on the conductor, thereby achieving obvious effects such as wind resistance, earthquake resistance, sway resistance and overturning resistance.
