Description

Technical Field

[0001] The invention belongs to the technical field of power transmission line construction, and in particular relates to a main shaft disassembly tool and a disassembly method for a conductor deployment reel. Background Art

[0002] Power conductors, especially power cables, are generally wound on cable drums for transportation, storage and laying. For low-voltage cables, wooden cable drums are mostly used, and medium-voltage cables are mostly steel cable drums; high-voltage and ultra-high-voltage cable drums are usually steel structures, and the protective plates are mostly thin iron sheets. The cable drum can protect the cable from damage during transportation. Before transporting the cable, it is necessary to check whether the specifications and models of the cable meet the requirements and ensure that the cable is intact. The inner and outer ends of the cable and the oil pipes between the oil-filled cable and the pressure box must be firmly fixed on the drum to avoid loosening due to vibration during transportation. When loading and unloading the cable drum, appropriate lifting equipment such as cranes should be used, and ensure that the cable drum is evenly stressed to avoid damage to the cable. It is strictly forbidden to lift several cable drums at the same time, and it is not allowed to push the cable drum directly from the transport vehicle. During transportation, the cable drum must be placed steadily and firmly fixed to prevent the cable drum from shaking, colliding or tipping over, and the cable drum is not allowed to be loaded flat, because laying flat will cause the cable to loosen, and the layers will squeeze each other, which is easy to damage the cable. By winding the cable, the conductor unwinding reel can avoid problems such as squeezing, bending and abrasion of the cable during storage and transportation, thereby reducing the failure rate of the cable and facilitating transportation and installation. When it is necessary to lay or unwind the cable, it is necessary to disassemble and assemble the main shaft of the conductor unwinding reel. For large-sized cables, the corresponding conductor unwinding reel and its main shaft are huge in size. Manual operation is not only inefficient, but also poses a safety hazard. Therefore, it is very necessary to provide a conductor unwinding reel main shaft disassembly tool and disassembly method. Summary of the invention
