The problems that in the prior art, although steel pipes with different lengths can be fixed, the length can be adjusted only by repeatedly screwing a plurality of fixing bolts during adjustment, adjustment is relatively tedious, the bolts are prone to being damaged, the transverse position where the steel pipes are placed is relatively fixed, the number of the placed steel pipes is limited, and therefore practicability is insufficient are solved.

This invention discloses a reinforced concrete joint inspection device, including a fixed base and an inspection component mounted on the fixed base for inspecting the joint structure. A bracket is welded to the back of the fixed base, and a rotating shaft is movably connected to the side of the bracket. A torsion spring is installed between the outer circumference of the rotating shaft and the side of the bracket. A lever is fixed to the outer circumference of the rotating shaft by a pin, with one end of the lever movably connected to an adjusting plate and the other end of the lever movably connected to a detection roller. The inspection component includes a guide plate fixed to the back of the fixed base by screws and a scale rod movably connected to the side of the guide plate. When the inspection roller encounters a protrusion on the transverse joint surface caused by pull, the lever rotates around the rotating shaft. Due to the different distances from the rotating shaft to the two ends of the lever, the lever principle amplifies the minute displacement of the inspection roller, making the change in the scale value of the scale rod relative to the guide plate more obvious, thus enabling more accurate detection of minute deformation defects on the joint surface.

The connecting assembly comprises two supporting plates extending in the direction away from the first steel channel, and the two supporting plates are connected with an upper wing plate and a lower wing plate of the first steel channel correspondingly. A reinforcing plate is connected between the two supporting plates, and a hanging screw is arranged at the end, away from the first steel channel, of one supporting plate and used for being connected with an oil tank cover. The surfaces, away from the upper clamping piece, of the two second steel channels of the lower clamping piece are connected with a bottom plate. And a plurality of third connecting rods are connected between the two pieces of first channel steel and the two pieces of second channel steel on the same side. The stress area between the connecting assembly and the upper clamping piece can be increased, and local stress concentration and damage caused by uneven stress of the upper clamping piece are prevented.
