A mounting adjustment platform for a prefabricated panel is characterized by comprising a vehicle body, a rotary shaft and a rocking handle thereof, a hydraulic jack, a bolt rod and a nut thereof, a stop wedge, and a data acquisition system, wherein the hydraulic jack is arranged in a groove of the vehicle body and is connected with the vehicle body through the rotary shaft, the top of a piston of the hydraulic jack is provided with a preformed hole, the bolt rod is arranged by penetrating through the preformed hole, the data acquisition system is connected with the hydraulic jack and is used for reading data and controlling the vertical displacement of the piston of the hydraulic jack. Through adjustment of corresponding components, the prefabricated panel is accurately located along the panel thickness direction and the panel length direction in a horizontal plane and is accurately located in a vertical direction, so that the problem that accuracy in installation and alignment of the prefabricated panel is difficult to realize through a crane is solved, therefore, the prefabricated panel is installed safely and reliably; and the operation is simple, construction and installation are convenient, construction cost is low, time for accurately locating the prefabricated panel in the prior art is shortened, construction is speeded up, and the comprehensive benefit is further improved.
