[0002] Existing subway stations and underground continuous walls are constructed in the form of on-site pouring, that is, the steel cage is wrapped with concrete slurry, and after the concrete solidifies, it is tightly combined with the steel cage to form the station's floor, wall panel or underground continuous wall. However, it is difficult to ensure the concrete ratio during on-site pouring, and the pouring site environment is uncontrollable. It is very easy for foreign matter to invade the unsolidified concrete, resulting in the station or underground continuous wall failing to meet the design indicators, leaving safety hazards for subsequent construction.

[0003] In order to ensure the quality of the station's building and underground continuous walls and improve construction efficiency, it is now planned to prefabricate a number of prefabricated wall panels. The prefabrication factory can control the production environment of the prefabricated wall panels and ensure the precise proportion of concrete for the prefabricated wall panels or prefabricated floor slabs.

[0022] The walking device 2 is located on the bottom surface of the base 1. The walking device 2 can adopt an existing wheeled walking device 2 or a crawler walking device 2. The walking device 2 is used to drive the base 1 to move on a working plane, wherein the working plane can be the bottom cushion layer of a subway station or a working platform built by a trolley.

[0023] The positioning assembly 3 includes a supporting device 31 and an adjusting device 32. The fixed end of the supporting device 31 is slidably connected to the base 1, and the movable end of the supporting device 31 abuts against the bottom surface of the prefabricated board. The spacing between the movable end and the fixed end of the supporting device 31 is adjustable, thereby adjusting the position of the prefabricated board in the vertical direction. Furthermore, the adjusting device 32 is used to drive the supporting device 31 to slide on the base 1, thereby adjusting the position of the prefabricated board in the horizontal direction. The mechanism can temporarily support the prefabricated board and transport the prefabricated board to a suitable position, and then accurately adjust the installation position and installation posture of the prefabricated board through the supporting device 31 and the adjusting device 32 (the installation posture includes the top surface elevation, horizontality, verticality, etc. of the prefabricated board) to ensure that the prefabricated board can be automatically and accurately assembled on the completed building.

[0024] The supporting device 31 includes a piston cylinder and a piston movably arranged in the piston cylinder. The piston cylinder can be filled with hydraulic oil.

[0025] The adjusting device 32 includes an adjusting arm 321 , one end of which is rotatably connected to the base 1 , and the other end of which is rotatably connected to the supporting device 31 .

[0026] The prefabricated plate positioning mechanism also includes a plurality of leveling devices 4, which are movably connected to the base 1, and the movable ends of the leveling devices 4 can move toward or away from the base 1 in the vertical direction, and the plurality of leveling devices 4 are used to level the base 1 so that the base 1 is kept horizontally arranged. The leveling device 4 can adopt an existing hydraulic cylinder, which is fixedly connected to the base 1, and a support foot is arranged on the piston rod of the hydraulic cylinder, and the support foot can be supported on the ground, and the piston rod telescopically moves in the hydraulic cylinder to adjust the horizontality of the base 1.

[0027] One or more distance sensors 11 are provided on the side of the base 1, and the sensing area of ​​the distance sensor 11 is arranged toward one side of the base 1.

In order to enable the prefabricated panels to press against the building, one or more fixing components are provided on the side of the base 1. The fixing components include a hook 13 and a rope 12. One end of the rope 12 is connected to the hook 13, and the other end is movably connected to the base 1.
