Device and method for detecting bumps on sleeving pipe

The invention discloses a device and a method for detecting bumps on a sleeving pipe, wherein the detection device comprising: a mounting plate with a center hole for a reinforcing component to pass and a plurality of mounting bases arranged along the circumferential direction of the mounting plate; detection parts arranged on each mounting base and capable of sliding in the passing direction of the sleeving pipe wherein in each detection part, a pair of opening and closing detection modules are mounted through an elastic element and when the pair of opening and closing detection modules are in clamped, they become conical body holes for the sleeving pipe to pass, and the conical body holes narrow in the passing direction of the sleeving pipe and the diameter at the small hole end of the conical body holes is greater than or equal to the diameter of the sleeving pipe; and sensors arranged at positions corresponding to the detection parts, wherein after the bumps of the sleeving pipe are pulled to the position
