[0002] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. They are communications cable assemblies that use one or more optical fibers in a sheath as transmission media and can be used individually or in groups. When relocating defense optical cables, a lifting device is required to lift and move them.

[0003] Among them, most traditional lifting devices are directly lifted by the lifting hooks and lifting belts that come with the lifting vehicle. When a single lifting hook and lifting belts on both sides are used to lift the optical cable, it is easy for the lifting belt to slide to one side during the pulling process, causing the optical cable to slide and fall, posing a safety hazard. Therefore, there is a defect that it is inconvenient to use for lifting, and thus it cannot meet the customer's usage needs. For this reason, we propose a national defense optical cable relocation lifting device to solve the above problems. Utility Model Content

[0033] Working principle: When it is necessary to relocate and hoist the national defense cable, the staff use the external hoisting vehicle and the hoisting ring 15 in cooperation to lift the hoisting device and move it to the hoisting position of the cable. Then, when the staff need to adjust the hoisting distance between the two hoisting hooks 6 according to the actual hoisting situation of the cable, the staff rotate the turning handle 13, so that the turning handle 13 drives the rotating shaft 8 to rotate, the rotating shaft 8 drives the main bevel gear 9 to rotate, the main bevel gear 9 drives the driven bevel gear 7 to rotate, and the driven bevel gear 7 drives the left and right threaded rod 3 to rotate threadedly on the inner surfaces of the two lengthening plates 4, so that the two lengthening plates 4 drive the threaded cylinder 5 and the hoisting hook 6 to move to a suitable hoisting distance. At the same time, the lengthening plate 4 drives the pin hole 102 to move to a position corresponding to the limit bolt 101. Then, the staff rotate the limit bolts 101 on both sides in turn, so that the limit bolts 101 are inserted into the inner cavity of the corresponding pin holes 102, thereby limiting the connection between the lengthening plate 4 and the positioning frame 1 and completing the adjustment of the hoisting distance between the two hoisting hooks 6. Then, the staff use the external hoisting belt in cooperation with the two hoisting hooks 6 to hoist and relocate the national defense cable, thus effectively avoiding the hoisting belt sliding to one side during the pulling process, resulting in the sliding and falling of the optical cable, which poses a safety hazard. The operation of this device is convenient for hoisting use, so as to meet the use requirements of customers.
