Title:
FULL-LENGTH VIBRATION EXCITABLE COMPONENT DEVICE FOR MEASURING STRENGTH OF ROCK AND GEL MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/087575
Kind Code:
A1
Abstract:
A full-length vibration excitable component device for measuring the strength of a rock and a gel material. The device comprises a steel rod member (1), a vehicle body (2), a vibration motor (3), a frequency measurement element (4) and an integrated lead harness (5), wherein a through slot (6) is provided in the steel rod member (1), the vehicle body (2) is placed in the through slot (6), and a first mounting slot and a second mounting slot are respectively provided on the top of the vehicle body (2). By means of the device, a large number of steel rod members (1) such as reinforcing steel bars and anchor rods used in geotechnical engineering and structural engineering are taken as "signal generators", the interior of each steel rod member (1) is grooved for having a movable vibration excitation apparatus and a frequency sensing element arranged therein, and the positions of the vibration excitation apparatus and the frequency sensing element are accurately determined by using an integrated lead harness (5) with scales, thereby realizing operations of performing excitation and signal collection at any position on the full length of the metal rod member. The vibration excitation and detection elements of the device can be recycled and reused, thereby facilitating maintenance, such that the detection cost can be significantly reduced.
