Ancient city wall efflorescent brick removing tool

The invention discloses an ancient city wall efflorescent brick removing tool and aims to solve the problem that vibration in the existing process of efflorescent brick removing is unfavorable for city wall stability and easily causes damage to intact bricks around. The ancient city wall efflorescent brick removing tool comprises a grabbing device, a counterforce system and a supporting arm steel rod, the counterforce system is composed of upper and lower subplates, two longitudinal connecting rods, extensible connectors and two transverse connecting rods, the upper subplate and the lower subplate are connected with the upper end and the lower end of the supporting arm steel rod respectively, the longitudinal connecting rods are in left-right arrangement, the transverse connecting rods are in upper-lower arrangement, the longitudinal connecting rods and the transverse connecting rods are connected through second connecting bolts, and two ends of the transverse connecting rods are connected with the subplates through the extensible connectors. By the ancient city wall efflorescent brick removing tool, bricks can be pulled out one by one with a removing device after drilling screws into to-be-removed bricks, so that interference to surrounding bricks in the process of removing is reduced, and city wall efflorescent brick removing efficiency can be improved while maintenance engineering cost is lowered.
