Movable maintenance device for shear wall concrete

The utility model relates to the technical field of building maintenance equipment, and discloses a shear wall concrete movable maintenance device which comprises a base, a supporting frame body is installed on the top of the base, and a fixing block is arranged in the supporting frame body. Under the action of the servo motor and the lead screw in the lifting mechanism, the fixed block can be driven to move up and down in a reciprocating manner, so that the main pipe drives the spray head to spray the wall surface of the shear wall more uniformly, a constructor does not need to carry out handheld operation, the fatigue degree of the constructor is reduced, the maintenance effect is better during spraying, and the maintenance efficiency is improved. The water receiving hopper and the wall surface of the shear wall are attached together, so that a water source sprayed on the wall surface can fall into the water receiving hopper, and the water source in the water receiving hopper can be conveyed into the water
