TROLLEY REPLACING DEVICE AND TROLLEY REPLACING METHOD

摘要

The present invention relates to a trolley replacing device and a trolley replacing method, which belong to the technical field of the replacement of a trolley of a sintering machine or a belt type roasting machine in the metallurgical industry. The trolley replacing device comprises a trolley, an inner straight rail, an inner curved rail, an outer straight rail, an outer curved rail, a main driving wheel, a trolley moving-out rail, and a trolley moving-in rail, wherein the outer curved rail arranged on both sides of the main driving wheel is divided into a lower movable outer curved rail, a middle fixed outer curved rail, and an upper movable outer curved rail; the lower movable outer curved rail is outwardly separated from the middle fixed outer curved rail and a lower outer straight rail on both sides vertical to the operating direction of the trolley, or is connected with the middle fixed outer curved rail and the lower outer straight rail; and one end of the upper movable outer curved rail is connected with one end of the trolley moving-in rail. The present invention enables the sintering machine or the belt type roasting machine to replace the trolley without stalling, and no additional time to replace the trolley is needed, thus increasing the production efficiency; because there are no operations such as stalling the sintering machine or the belt type roasting machine and reducing or stopping the wind, the production condition will not be changed and will be stable relatively; and because of the stable production condition, the production pass rate and the tumbler index will not be reduced.
