Multifunctional crack detection equipment for constructional engineering

The utility model relates to the field of crack detection equipment, and discloses multifunctional crack detection equipment for constructional engineering. Two sets of limiting plates are welded to the upper surface of the base, a lifting platform is movably connected between the limiting plates at the two ends, a supporting circular ring is welded to the lower surface of the lifting platform, a second hydraulic cylinder is arranged on the lower surface of the supporting circular ring, and the lower surface of the second hydraulic cylinder is welded to the upper surface of the base. A clamping groove is formed in the upper surface of the lifting platform, a movable baffle is movably connected into the clamping groove, a crack detector is arranged on the outer surface of the side, away from the lifting platform, of the movable baffle, and a worker pushes the lifting platform to move by starting a second hydraulic cylinder, so that the height of the lifting platform can be adjusted; meanwhile, the contact surf
