Description

Technical Field

[0001] The present application relates to the technical field of wiring, and in particular to a wiring device for high-voltage overhead lines. Background Art

[0002] High-voltage power construction and wiring are the key links in power engineering. It mainly builds a structure that carries the conductors for high-voltage transmission lines on the planned line path. First of all, detailed planning and surveying are required before construction to determine the line direction, pole tower location, etc., and consider many factors such as terrain, meteorological conditions, and surrounding environment. In actual construction, pole towers must be installed first. There are various types of pole towers, including iron towers, cement poles, etc. They are like solid "skeletons". Through foundation construction, the pole towers are firmly established on the ground. Then comes the wiring part, which requires tensioning the wires by using traction machines and tension machines to make the wires at a certain height. The wires are laid out under tension control to avoid damage caused by excessive friction between the wires and obstacles such as the ground. Construction workers also need to connect the ground wires, using methods such as crimping to ensure a firm connection and good conductivity. At the same time, insulator strings will be installed to suspend the wires to play an insulating and supporting role to prevent current leakage to the towers. In addition, the wire stringing process also involves crossing obstacles such as roads, railways, rivers, etc., which require the use of special crossing frames or the use of navigation closures to safely complete the laying of wires. The entire high-voltage power construction wire stringing process is complex and requires strict quality control and safety measures to ensure the stable operation of high-voltage transmission lines. During the installation, maintenance and replacement of high-voltage electric wires, construction workers often need to climb and pull the lead wires, which is labor-intensive and time-consuming, affecting construction efficiency. To address this problem, a Chinese patent with the announcement number "CN219304330U" discloses a wire-hanging device for high-voltage electric power construction. The device includes a base, a through slot, a sliding slot, a lifting device 1 and 2, a clamping device, a universal wheel and a push handrail. Through the coordinated adjustment of the lifting device 1 and 2, the operator can install the lead wires at different heights, reduce the climbing and pulling operations, save time, and improve work efficiency. Its reasonable structure brings convenience to high-voltage electric power construction. This device has obvious deficiencies in practical applications. It lacks the line tensioning function during use. At present, in some special high-voltage power equipment, such as the connecting wires for movable high-voltage electrical test equipment, or in environments with vibration and dynamic loads such as offshore wind power platforms, high-voltage wires are required to withstand a certain degree of bending, torsion and other deformations without breaking. Therefore, soft high-voltage wires are used to adapt to these complex and changeable working conditions to ensure the stability of power transmission and the safety of equipment. Obviously, during the application of these relatively soft special high-voltage wires, when there are redundant lines, the overall line will be dragged, resulting in chaotic layout, and the wind-exposed area will be greatly increased. After the wind-exposed area increases, the line will be subjected to stronger force under the action of wind, and the wind resistance will be greatly weakened. Under severe weather conditions, the line is more susceptible to damage, thereby greatly reducing the service life. In addition, the line lacks buffering performance due to the lack of tensioning structure. During the wiring process, once it is impacted by external forces, such as wind changes and other unexpected factors, if there is no buffering performance, the external force will directly act on the line, which is easy to cause line breakage, insulation layer damage and other damages, which also affects the life of the line. At the same time, the device also has the problem of inconvenience in quickly and synchronously adjusting the clamp to clamp the cable. In the wiring operation, it is very important to clamp the cable quickly and accurately, but the design of this device is insufficient, making the wiring operation cumbersome and inconvenient. The operator needs to spend more time and energy to adjust the clamp, which reduces work efficiency and increases the difficulty and risk of operation. In order to meet the needs of high-voltage power construction, improve construction quality and efficiency, and ensure the safe and stable operation of the line, it is necessary to improve the device.

With the movement of the bottom hinge, the scissor-type telescopic frame is assisted in extending. At the same time, the top hinge slides in the upper slide groove to reserve space for the extension of the scissor-type telescopic frame. Through the linkage guide of the upper and lower slide grooves and the hinged seat, the top and bottom hinges slide synchronously, thereby pushing the entire top seat to rise. The scissor-type telescopic frame adopts a multi-group frame joint hinge design, and different sizes and specifications can be selected according to actual needs.

At this time, the clamping plate squeezes the telescopic spring to further clamp the cable, ensuring that the cable is stably inside the clamping plate, and the wire-laying work is successfully completed. The tensioning mechanism provided in this device plays a significant role during cable laying. The cable is passed through the reserved groove in the middle of the reel, and the second motor is started to assist in driving all the reel wheels to rotate, so as to reel in the cable. During application, the weight of the cable will compress the torsion spring. By adjusting the number of turns driven by the second motor to rotate the shell, the overall compression of the torsion spring can be adjusted. On the one hand, reeling in the cable can cause the line to be tightened as a whole, which is convenient for reeling in excess line. On the other hand, when the cable is subjected to wind pressure or extrusion, the cable moves on the inner side of the clamping plate through the ball bearing, causing the torsion spring to rotate and retract adaptively, thereby achieving better buffering performance. Moreover, when the cable is wrapped around the outer surface of the reel, the cable will overlap the transmission shaft, and the pressure on the entire cable will act on the pressure sensor. The pressure sensor can be used to assist in detecting the overall pressure of the cable, thereby facilitating the use of this device. BRIEF DESCRIPTION OF THE DRAWINGS

The wire-hanging mechanism 5 is mainly composed of the guide rail 51 fixedly mounted on the front and rear sides of the top of the top seat 4. Three screw rods 52 are rotatably connected inside the guide rail 51 at equal intervals and are fixedly connected to each other. This design ensures that the three screw rods 52 can rotate synchronously, thereby improving the coordination and stability of the operation. The threads at both ends of the rod 52 are rotated in opposite directions, so that the cable stringing components 53 at both ends can move inward or outward at the same time when the screw rod 52 rotates, which is convenient for clamping and fixing cables of different sizes.

[0024] The implementation principle of the overhead line stringing device of the high-voltage overhead line of the present application embodiment is as follows: by setting the lifting mechanism 2, the electric push rod 23 can be started to operate during the use of the device. When the electric push rod 23 is in operation, it will push the hinge 26 at the bottom to slide inside the lower slide groove 22. At this time, the movement of the hinge 26 can assist in pushing the scissor-type telescopic frame 27 to extend. At the same time, the top hinge 26 slides inside the upper slide groove 21 to reserve space for the scissor-type telescopic frame 27. The top and bottom hinges 26 slide synchronously, and then cooperate with the linkage guide of the upper slide groove 21, the lower slide groove 22 and the hinge seat 24, and then the entire top seat 4 can be pushed up.

In addition, the scissor-type telescopic frame 27 is a multi-group frame joint hinge design as a whole. Scissor-type telescopic frames 27 of different sizes can be selected according to needs. In this way, the top seat 4 can be lifted to a higher and more suitable position, thereby improving the overall use adaptability of the device. By setting up the wire-laying mechanism 5, when the device needs to lay wires, the cable can be placed between the inner sides of the two clamping plates 5342, and the cable can be pressed downward and guided by the guide plate 5345. At this time, the telescopic spring 5341 will be caused to contract, and the cable can be placed on the inner side of the clamping plate 5342. In this reciprocating operation, multiple cables can be placed between the inner sides of the clamping plates 5342. At this time, the first motor 34 is started to run, and the first motor 34 can drive the worm 33 and the worm wheel 32 to cooperate in transmission, and then, all the screw rods 52 inside the two guide rails 51 can be synchronously driven to rotate. The threads at both ends of the screw rod 52 rotate in opposite directions. At this time, all the sliders 531 can be synchronously driven to slide, and then, the clamping plate 533 can be driven to move further inward, causing the clamping plate 5342 to squeeze the telescopic spring 5341 to further clamp the cable. In this way, the cable can be stably located on the inner side of the clamping plate 5342 to complete the wire-laying. By setting the tensioning mechanism 6, the device can pass the cable through the reserved groove 67 in the middle of the reel 65 during the cable laying. At this time, starting the second motor 68 can assist in driving all the reel 65 to rotate. The cable can be reeled in by rotating the reel 65. During the application process, the weight of the cable will cause the torsion spring 64 to be in a compressed state. By adjusting the number of revolutions of the housing 62 driven by the second motor 68, the overall compression of the torsion spring 64 can be adjusted. During this period, on the one hand, the line can be tightened as a whole by reeling in the cable, which is convenient for reeling in excess line. On the other hand, The tension of the torsion spring 64 can buffer and reduce shock for the entire cable. When the cable is subjected to wind pressure or extrusion, the cable moves on the inner side of the clamping plate 5342 through the ball 5343, causing the torsion spring 64 to adaptively rotate and retract, which can provide better buffering performance. In addition, during application, when the cable is wound around the outer surface of the reel 65, the cable is just overlapped with the transmission shaft, which can assist in the transmission of the cable. The pressure on the entire cable acts on the pressure sensor 662, which can assist in detecting the pressure condition of the entire cable, making it convenient to use the device.

[0025] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
