Trolley replacing device and trolley replacing method

摘要

pThe present invention relates to a device for replacing trolley and a method for replacing trolley, is belong to the technical field that the sintering machine, the belt-type roasting machine replaces the trolley in the metallurgical industry. The device for replacing trolley comprises a trolley, inner straight tracks, an inner curved track, an outer straight track, outer curved tracks, a main drive wheel, a trolley feed-out track, a trolley feed-in track, wherein, the outer curved tracks on the two sides of the main drive wheel are divided into a lower movable outer curved track, a middle fixed outer curved track, and an upper movable outer curved track; the lower movable outer curved track is separated outward from the middle fixed outer curved track and a lower outer straight track or connected outward to the middle fixed outer curved track and the lower outer straight track on the two sides perpendicular to the operating direction of the trolley; one end of the upper movable outer curved track is connected to one end of the trolley feed-in track. The present invention can achieve the trolley replacement of the sintering machine, the belt-type roasting machine in the condition of non-stop, the additional replace time for replacing trolley is not needed, the production efficiency is increased. There are not the operations such as stopping the sintering machine or the belt-type roasting machine and performing the operation to reduce wind or stop wind, the production condition is not changed and is relatively stable. The pass rate of the product and the drum index do not reduce due to the stable production condition./p
