The invention relates to an adjustable stranded wire clamping conveying device, which belongs to the technical field of building construction. At least two fixing shaft strand pulling wheels driven by gear transmission are supported on a frame of the device; swinging strand pulling racks are hinged on the wheel shafts of the fixing shaft strand pulling wheels, respectively; the upper ends of the swinging strand pulling racks are hinged through connecting plates; adjusting bolts with ends butted against the connecting plates are arranged on the frame; and the swinging strand pulling racks support the swinging shaft strand pulling wheels which clamp stranded wires together with the corresponding fixing shaft strand pulling wheels. The use method of the device comprises steps of enabling the stranded wires to pass though the fixing shaft strand pulling wheels and the corresponding swinging shaft strand pulling wheels, adjusting the adjusting bolts, and changing the clamping pitch of the fixing shaft strand pulling wheels and the swinging shaft strand pulling wheels to the stranded wires through the swinging of the connecting plates, so as to reliably clamp the stranded wires. When the strand pulling wheels are driven to rotate, the stranded wires are stably conveyed out.
