Abstract
The invention discloses a stress wave sensor positioning device for detecting a defect of an ancient architecture timber component. When a longitudinal timber component is detected, a detection section sensor positioning device is rotated, a proper longitudinal detection section height is pulled under the action of the gravity of a drop hammer, a sensor distribution positioning measuring ruler is pulled after a detection section is determined, and is fixed by an automatic buckle and a magic tape, and the circumference of the member is quickly determined, so that the position of each sensor can be quickly obtained according to the quantity of stress wave sensors. When a transverse longer timber member is detected, the magic adhesive strips can be fixed at the end part of a detection beam/cross bar and are reversely adhered with the end part of the detection section positioning measuring ruler; the section positioning measuring ruler is pulled to the detection section position; after the detection section is determined, the sensor distribution positioning measuring ruler is pulled to quickly determine the distribution positions of the sensors. According to the stress wave sensor positioning device, the problems that the conventional ruler is slipping, the detection section is unbalanced and the like are reduced; meanwhile, the working intensity of a detector is reduced, and the detection efficiency is effectively improved.
