The invention provides a recovering device for an iron tower component, and belongs to the technical field of iron tower overhauling tools. The device comprises a support, and lever type clamps whichare symmetrically arranged on the support, wherein each clamp comprises a driving part which is connected to a power device, and a clamping part for clamping the iron tower component; the driving parts and the clamping parts are correspondingly positioned at two ends of the clamps, and the two clamps are correspondingly hinged with the support; and the two driving parts are correspondingly connected to the power devices through intermediate connectors. According to the device, the two driving parts are correspondingly driven to move away from the iron tower component through the power devices,and the deformed part of the iron tower component is clamped through the two clamping parts, and thus the deformed part of a power transmission iron tower component can be recovered to be flat and straight under the effect of the clamping force of the two clamping parts, and bolt holes of the recovered power transmission iron tower component and another iron tower component can be moved, and thusthe working efficiency of removing fault of a power transmission iron tower can be improved. The device is simple in structure, and low in manufacturing cost; and the workload of construction workersis decreased.
