Description

Technical Field

[0001] This invention relates to the field of cable repair tools, specifically a tool for repairing and installing cables on transmission towers. Background Technology

[0002] Transmission towers are critical structures supporting the conductors and lightning protection wires of high-voltage or ultra-high-voltage overhead transmission lines. Any abnormality in the fixed cables of these towers can severely impact residents' lives and industrial production, and may also pose safety hazards. Emergency repairs and maintenance of these cables can minimize the negative impacts of power outages.

[0003] During emergency repairs, maintenance workers must climb to high positions on transmission towers. If tools are incomplete, workers must repeatedly climb up and down the tower to change tools, significantly increasing labor intensity and severely reducing repair efficiency. Furthermore, some repair scenarios require disassembling cables for inspection, after which the cables sag due to their own weight. The reinstallation process after repair requires considerable manpower to tighten the cables. These operations not only significantly deplete the physical strength of maintenance personnel but also significantly increase safety risks during the work process.

[0004] Therefore, this invention proposes a cable emergency repair and installation tool for transmission towers, allowing ground maintenance personnel to transport the tools to the work site, thereby reducing the number of times maintenance personnel need to repeatedly climb the transmission tower. Furthermore, by securing the cable, the reinstallation process after disassembly is simplified, improving emergency repair efficiency. Summary of the Invention

[0034] Please see Figure 1-6A cable repair and installation tool for transmission towers includes an I-beam plate 11. A U-shaped clamp 12 is rotatably mounted on the back of the I-beam plate 11. One end of the U-shaped clamp 12 is hinged to a clamping plate 13. When the U-shaped clamp 12 and the clamping plate 13 are closed, an L-shaped gap is left between them. Most existing transmission towers are constructed by welding or bolting angle steel. The L-shaped gap between the U-shaped clamp 12 and the clamping plate 13 facilitates the clamping of the U-shaped clamp 12 and the clamping plate 13 onto the angle steel of the transmission tower. Two sets of each U-shaped clamp 12 and clamping plate 13 are provided, symmetrically arranged on both sides of the I-beam plate 11. During installation, the angle of the U-shaped clamp 12 can be adjusted by rotation to align it with the angle steel, thus facilitating the clamping of the U-shaped clamp 12 onto the outside of the angle steel. After both sets of U-shaped clamps 12 and the clamping plates 13 are fixed to the angle steel, the I-shaped plate 11 connected to the U-shaped clamps 12 will also be fixed because the two shafts that are rotatably connected to the U-shaped clamps 12 are fixed.

[0035] A slotted hole is provided on the clamping plate 13, and a locking stud 15 that can pass through the slotted hole is welded on the U-shaped clamp 12. When the clamping plate 13 and the U-shaped clamp 12 are clamped to the outside of the angle steel, the locking stud 15 passes through the slotted hole, and then the locking plate 16 is screwed to the outside of the locking stud 15. The locking stud 15 applies pressure to the U-shaped clamp 12 and the clamping plate 13, so that the U-shaped clamp 12 and the clamping plate 13 can be tightly clamped to the outside of the angle steel.

[0036] A guide slider 21 is slidably fitted on the outer side of the I-beam 11. The guide slider 21 can be detached from the I-beam 11. A cable clamp, lifting auxiliary device, or maintenance box is connected to the end of the guide slider 21 away from the I-beam 11. Maintenance personnel can replace the guide slider 21 with the cable clamp, lifting auxiliary device, or maintenance box as needed. Alternatively, multiple I-beams 11 can be installed on the transmission tower, and guide sliders 21 with cable clamps, lifting auxiliary devices, or maintenance boxes can be installed on the outer side of different I-beams 11.

[0037] A locking rack 14 is provided on the outer side of the I-beam plate 11. A positioning rack 23 is slidably mounted on the guide slider 21. An adjusting screw is rotatably connected to the upper side of the positioning rack 23. A threaded groove is provided on the guide slider 21 to be screwed to the adjusting screw. The upper end of the adjusting screw extends out of the threaded groove of the guide slider 21 and is connected to a rocker arm 22. Rotating the rocker arm 22 causes the adjusting screw to rotate and move up and down. The adjusting screw pushes the positioning rack 23 to move up and down. When the positioning rack 23 moves upward and separates from the locking rack 14, the guide slider 21 can slide normally. When the positioning rack 23 moves downward and engages with the locking rack 14, the guide slider 21 is fixed and cannot slide.

[0038] The cable clamp includes a lower clamping plate 54 and an upper clamping plate 55. A connecting rod 51 is hinged to the lower side of the lower clamping plate 54, and the other end of the connecting rod 51 is hinged to the guide slider 21. By rotating the connecting rod 51 and the lower clamping plate 54, the lower clamping plate 54 is aligned with the cable 60. Then, the upper clamping plate 55 is installed on the lower clamping plate 54 to clamp the cable 60. An adjusting rod 52 is hinged to the outer side of the guide slider 21. The adjusting rod 52 has a slot. The adjusting rod 52 intersects with the connecting rod 51. A clamping stud is provided on the outer side of the connecting rod 51. One end of the clamping stud extends out of the slot, and a clamping rocker 53 is screwed to the outer side of the extended end of the clamping stud. Tightening the clamping rocker 53 fixes the adjusting rod 52 and the connecting rod 51 by pressure. Due to the stability of the triangle, the connecting rod 51 is fixed and cannot rotate at this time. The shaft used at the hinge joint between the connecting rod 51 and the lower clamping plate 54 is a hinge screw. The threaded end of the hinge screw extends out of the connecting rod 51 and the lower clamping plate 54 and is screwed to clamp the connecting rod 51 and the lower clamping plate 54. Tighten the fixed rocker arm 56, and the fixed rocker arm 56 will squeeze and clamp the connecting rod 51 and the lower clamping plate 54 through pressure, so that the two cannot rotate relative to each other.

[0039] Both the lower clamping plate 54 and the upper clamping plate 55 have detachable clamping plates 58 on their adjacent sides. The outer side of the clamping plate 58 has a wire groove, through which the cable 60 passes. The clamping plate 58 is semi-circular, with an adapter plate on the opposite side of its arc end. The adapter plate of the clamping plate 58 is fixed to the lower clamping plate 54 or the upper clamping plate 55 by bolts. The upper clamping plate 55 has one more clamping plate 58 than the lower clamping plate 54. The clamping plates 58 on the upper and lower sides are staggered, and the cable 60 is clamped and fixed by the clamping plates 58 on the upper and lower sides squeezing each other.

[0040] A mounting groove is installed on the upper side of the lower clamping plate 54. A worm gear 572 and a worm wheel 573 are rotatably connected to the inner side of the mounting groove. The worm gear 572 meshes with the worm wheel 573. One end of the worm gear 572 extends out of the mounting groove and is connected to an adjusting plate 571. By rotating the adjusting plate 571, the worm gear 572 drives the worm wheel 573 to rotate. A sealing plate is installed on the upper side of the lower clamping plate 54 to cover the worm gear 572 and the worm wheel 573 to prevent them from falling off. A positioning stud 59 is provided at the lower end of the upper clamping plate 55. A threaded groove is opened in the center of the worm wheel 573 in the axial direction. A through hole corresponding to the threaded groove is also opened on the sealing plate. The positioning stud 59 passes through the through hole and can be screwed into the threaded groove of the worm wheel 573. By rotating the worm wheel 573, the positioning stud 59 is pulled down, and the positioning stud 59 drives the upper clamping plate 55 down, so that the upper clamping plate 55 can clamp the cable 60 with the lower clamping plate 54.

[0041] The lifting aid includes a reinforcing rod 31 fixedly connected to a guide slider 21. A pulley 32 is rotatably connected to the other end of the reinforcing rod 31. When maintenance personnel climb the transmission tower, they carry an I-beam 11, the guide slider 21 with the pulley 32, and a rope. After fixing the I-beam 11 and the guide slider 21, the rope is passed through the pulley 32. Ground maintenance personnel can use the rope to send maintenance tools upwards, thereby reducing the number of times maintenance personnel need to climb up and down the transmission tower.

[0042] An adapter plate 34 is installed on the outer side of the reinforcing rod 31. The other end of the adapter plate 34 is connected to an M-shaped baffle 33 via a hinge. The M-shaped baffle 33 is positioned outside the pulley 32. Rotating the M-shaped baffle 33 disengages it from the pulley 32, allowing the pull rope to pass through. Closing the M-shaped baffle 33 then reconnects the reinforcing rod 31. The M-shaped baffle 33 prevents the pull rope from falling off the pulley 32. The M-shaped baffle 33 and the reinforcing rod 31 are connected using a snap-fit ​​connection or other detachable connection method.

[0043] The repair kit includes a body 42, with a cover 41 and a protective cover 43 rotatably connected to the upper side of the body 42. An L-shaped hook (not shown in the figure) is provided on the outer side of the cover 41, and a hanging groove (not shown in the figure) is provided on the outer side of the guide slider 21. By inserting the L-shaped hook into the hanging groove, the repair kit can be hung on the outside of the guide slider 21. Both the cover 41 and the protective cover 43 are connected to the body 42 by snap-fit ​​fasteners. The protective cover 43 is located between the cover 41 and the body 42. During installation, it is first connected to the guide slider 21, and then the cover 41 is opened. Since the protective cover 43 remains closed at this time, the repair tools inside the body 42 will not fall out. A protective strap is provided between the body 42 and the cover 41. When the protective strap is straightened, the body 42 is perpendicular to the cover 41. The protective cover 43 is opened only after the cover 41 is fully opened.

[0044] Magnets are embedded in both the side of the protective cover 43 near the box cover 41 and the side of the box cover 41 near the protective cover 43. When the protective cover 43 is opened, the magnets on the protective cover 43 and the magnets on the box cover 41 are aligned, and the magnetic poles on both sides are opposite. At this time, they will attract each other, thus preventing the protective cover 43 from closing automatically.

[0045] Working principle: First, maintenance personnel carry the I-beam plate 11, the guide slider 21 with pulley 32, and the rope to climb the transmission tower. Then, they rotate and adjust the angle of the U-shaped clamp 12 on the I-beam plate 11 to align it with the angle steel. Then, they remove the locking plate 16, open the U-shaped clamp 12 and the clamping plate 13. After the U-shaped clamp 12 and the clamping plate 13 are placed on the outside of the angle steel, they close the U-shaped clamp 12 and the clamping plate 13 and tighten the locking plate 16 to clamp the angle steel and fix it to the transmission tower.

[0046] The guide slider 21 with pulley 32 is fitted onto the I-beam plate 11, and the rocker arm 22 is tightened to engage the positioning rack 23 with the locking rack 14, thus fixing the guide slider 21. Then, the M-shaped baffle 33 is opened, the pull rope is passed through the pulley 32, and then the M-shaped baffle 33 is closed. Ground maintenance personnel can then use the pull rope to send cable clamps, maintenance boxes, and other maintenance tools from the ground to the baffle.

[0047] When securing cable clamps or maintenance boxes, first fix the guide sliders 21 corresponding to the cable clamps or maintenance boxes onto the I-plate 11. When installing the maintenance box, simply insert the L-shaped hooks on the box cover 41 into the hanging slots on the guide sliders 21. When installing cable clamps, after fixing the corresponding guide sliders 21 onto the I-plate 11, the cable clamps will be secured to the I-plate 11.

[0048] Before disassembling and repairing cable 60, first remove the upper clamping plate 55, then pass cable 60 through the clamping plate 58 of the lower clamping plate 54. Next, insert the positioning stud 59 on the upper clamping plate 55 into the threaded groove of the worm gear 573. Then, rotate the adjusting plate 571, which drives the worm 572 and worm gear 573 to rotate. The worm gear 573, through rotation, drags the positioning stud 59 and the upper clamping plate 55 downwards. Finally, the clamping plates 58 on the upper clamping plate 55 and the lower clamping plate 54 come together, clamping cable 60. Then, remove cable 60 from the transmission tower for emergency repair. After the emergency repair is completed, simply reinstall cable 60 onto the tower.
