The invention provides a lifting and transporting device for maintaining parts of fully-mechanized coal mining equipment of an air return way and belongs to the field of lifting and transporting devices. The lifting and transporting device aims at solving the problems that a current air return way conveys the maintaining parts by means of a manual dragging manner, so that the labor intensity is high, the working efficiency is low, and new accessories are easy to damage. The lifting and transporting device comprises an upper guide sliding track, chains, shackles, an up-down track connecting mechanism, a lower bearing track, a lifting mechanism, a walking hydraulic cylinder and two brake mechanisms. The upper guide sliding track is connected with hoisting holes in a forepoling bracket arranged in the air return way through the chains and the shackles. The lower bearing track is arranged under the upper guide sliding track. The upper guide sliding track is connected with the lower bearingtrack through the up-down track connecting mechanism. The lifting mechanism, the two brake mechanisms and the walking hydraulic cylinder are arranged under the lower bearing track. The first brake mechanism is connected with the front end of the lifting mechanism. The rear end of the lifting mechanism is connected with an end head of a piston rod of the walking hydraulic cylinder. The rear end ofthe walking hydraulic cylinder is connected with the second brake mechanism.
