Detection device

The utility model provides a detection device. The device comprises a positioning mechanism, a laser detection mechanism and a control mechanism, a laser detection mechanism is placed at a first operation position or a second operation position of a pier column; the laser detection mechanism can scan and measure the distance of the pier column from top to bottom at a preset angle. And the controlmechanism can obtain the verticality of the bridge pier stud through the corresponding relation between the detection result of the laser detection mechanism and the preset design parameters, the working efficiency of detecting the verticality of the pier stud is improved, the detection precision is high, and the detection range is large.
