The invention discloses a moving cable distribution vehicle for farm distribution network line bypass building and a use method thereof. The moving cable distribution vehicle comprises a driving device of a cable turntable, a caterpillar band base plate and a cable turntable, wherein the caterpillar band base plate comprises a base plate power device, two caterpillar bands and a support frame for supporting the caterpillar bands; the front end and the back end of the support frame are respectively provided with a caterpillar driving wheel and a guide wheel, a band supporting wheel is arranged at the upper side of the support frame; a weight supporting wheel is arranged at the lower side of the support frame; the driving device is fixed on the support frame; the cable turntable is arranged above the driving device. In order to improve the rotation stability of the cable turntable, a clamping device with an adjustable gap is also arranged right under a peripheral ring of the end part. In the use process, the driving device and the clamping device of the cable turntable are firstly arranged on the support frame of the caterpillar band base plate; then, the peripheral ring arranged at the end part of the cable turntable is supported by the power wheel of the driving device; the peripheral ring is clamped by two rolling wheels of the clamping device. The walking of the whole vehicle is realized by the caterpillar band base plate; the driving device enables the cable turntable to rotate in positive or reverse direction so as to realize the cable reeling and unreeling.
