Iron tower foundation eccentricity measuring device capable of preventing tower falling based on center distance

The invention discloses an iron tower foundation eccentricity measuring device capable of preventing tower falling based on a center distance. The iron tower foundation eccentricity measuring device comprises a first positioning pipe, a second positioning pipe is arranged at the top end of the first positioning pipe, a measuring scale is arranged at the top end of the second positioning pipe, and a fixing mechanism is arranged in the middle of one side of the second positioning pipe. The device is scientific and compact in structure and easy and convenient to operate, the first positioning pipe and the second positioning pipe can be in a cross shape and located at the quartering tangent position of the iron tower foundation according to the size of the iron tower foundation, and therefore the center point of the iron tower foundation can be determined; the center distance between the center point of the iron tower foundation and the center point of the foundation bolt of the iron tower foundation can be measu
