The invention provides a non-stop rope-climbing robot for detection, aiming at effectively solving the problem that a detection target can be replaced after a machine is stopped. The non-stop rope-climbing robot comprises an electric push rod, wherein an upper fixed plate is fixedly mounted at the upper end of the electric push rod; a first supporting arm is arranged at the upper end of the upperfixed plate; a first limb and a second limb are symmetrical relative to the electric push rod; a lower fixed plate is fixedly mounted at the lower end of the electric push rod; a second supporting armis arranged at the lower end of the lower fixed plate; the first limb comprises an arc-shaped rail; the arc-shaped rail is fixedly mounted at one end of the first supporting arm; the arc-shaped railis internally provided with an arc-shaped guide rail in a sliding manner; a supporting rod is fixedly connected with an inner side surface of the arc-shaped guide rail; the end part of the supportingrod is fixedly connected with a fixed block. According to the non-stop rope-climbing robot for detection, provided by the invention, four limbs of the robot can be more firmly attached on a rope and the safety degree is extremely increased; a full-automatic control type rotating and ascending structure is adopted, so that the rope-climbing robot can be moved to the rope at the upper side, withoutthe need of manual transportation and installation; therefore, the manpower is saved, and the working efficiency is extremely improved.
