The invention provides a rotating rail replacing device which is arranged on the top or the bottom of a guide rail bracket allowing two construction elevator cages to move up and down or other portions where rails need to be replaced. The rotating rail replacing device comprises a fixed rack body, a rotating rack body and rails. The rotating rack body comprises an upper rotating transition joint, a middle joint and a lower rotating transition joint which are sequentially connected from up to bottom. The upper rotating transition joint and an upper fixed transition joint are connected in a rotating mode through a bearing and are locked through a rotating locking device, the lower rotating transition joint and a lower fixed transition joint are connected in a rotating mode through a bearing and are locked through a rotating locking device, and the rotating rack body rotates along a rotating shaft where the bearings are placed. The number of the rails is two, and the rails are in central symmetry relative to the rotating shaft. Each rail comprises a fixed rack body section and a rotating rack body section. The rotating rail replacing device is suitable for rail replacing under the condition that the rails cannot form a loop, the problem that an elevator cannot achieve rail replacing in existing rack and gear type construction is solved, the need for replacing the rails quickly and reliably is met, the utilization rate of the rails is improved, the effect is improved, and the cost is saved.
