Abstract

Disclosed is a device for detecting wall abrasion of a solid-filling feeding well and a detection method thereof. The device comprises a well wall abrasion detector, a horizontal displacement meter, a vertical displacement monitor, and a limit guide rod. One end of the limit guide rod is connected to the well wall abrasion detector. The signal output terminal of the well wall abrasion detector is connected to the signal input terminal of the horizontal displacement meter, and the other end of the limit guide rod passes through the vertical displacement monitor for slidable setting. This disclosure mainly utilizes a resistance strain displacement sensor to detect the abrasion and deformation degree of the well wall, determines the position of damages with the vertical displacement monitor, and draws wall abrasion curves by using the obtained data. The device provided is easy to use, has low cost, has high reliability, and can effectively detect the wall abrasion condition of a solid-filling feeding well, thereby providing a basis for ensuring the working efficiency of the feeding well.
