Embodiment Construction
[0047] like Figure 1~Figure 10 As shown, a portable rural network line sag adjustment device includes a support frame 1, and the front and rear ends of the support frame 1 are respectively equipped with a fixed pulley 2 for guiding and two threading shackles 6; A winch 7 is installed in the middle of the support frame 1, and a polymer Dyneema rope with a certain number of turns is wound on the winch 7, and the winch 7 is connected with the large gear 8 and the ratchet mechanism (the ratchet 5 and the stopper). The back ratchet 4) rotates coaxially; a reversing knob 3 is installed next to the non-return ratchet 4; a pinion 9 and a winding shaft 11 coaxially rotating with the pinion 9 are also installed next to the winch 7, and at the same time There is also a crank handle 10 that rotates coaxially with the pinion 9 to provide an initial driving force; the bull gear 8 and the pinion 9 together constitute a gear transmission system to transmit power for the device.
