The invention relates to a double-pitch double-pin-shaft heavy load type conveying chain which is formed by connecting and assembling multiple chain link units. The chain link units include inner chain plates, outer chain plates, pin shaft sets and guide plates. The inner chain plates and the guide plates are arranged on the inner sides of the outer chain plates, and the guide plates are matched with guide grooves in chain wheels so as to limit transverse playing of the conveying chain. The pin shaft sets include short pin shafts and long pin shafts which can roll relatively. The inner chain plates and the guide plates are installed in a stacked manner, and first shaft holes penetrating the inner chain plates and the guide plates are formed. The short pin shafts and the long pin shafts penetrate the first shaft holes, and the rotation of the short pin shafts is limited in the circumferential direction of the first shaft holes. The two end portions of the long pin shafts stretch in thefirst shaft holes and are
