Within each rolling system, the two horizontal rollers are spaced 200mm apart. Four vertical rollers and four vertical shafts form four rolling systems, with the vertical rollers rotating around the vertical shafts. The connecting rods are welded perpendicularly to the center of the two horizontal shafts at both ends. The lower end of the vertical rod is welded perpendicularly to the middle of the connecting rod. One end of the cantilever rod is welded perpendicularly to the top of the vertical rod. A lug is welded to the outer end of the cantilever rod. The pendant is attached to the lug and allowed to hang freely. During use, the detection device is placed on the frame beam, with the horizontal rollers contacting the upper surface of the frame beam and the vertical rollers contacting the side of the frame beam. The detection device is then operated to move left and right on the frame beam, with the pendant hanging down to the side of the secondary structure wall. A ruler or tape measure is then used to check the verticality of the secondary structure wall at any time. The detection device is simple to assemble, easy to operate, simple and practical, and solves the problem of vertical and horizontal hanging lines of secondary structures, making the verticality of secondary structure masonry more accurate, while also reducing personal injuries and lowering safety hazards.
