[0040] An automatic spraying arm 16 is arranged inside the protection structure 43. The function of the automatic spraying arm 16 is to spray the anti-corrosion medium on the thin floor on both sides. In this embodiment, the automatic spraying arm 16 is a prior art structure and is controlled by a preset PLC program.

[0041] A column 17 is provided on each side of the base 1, a retractable shell 18 is fixedly installed on the top of the column 17, and a lifting rod 19 is provided on the top of the retractable shell 18. In the present embodiment, the lifting rod 19 is a prior art structure and will not be described in detail here. A cross bar 20 is welded on the top of the lifting rod 19, and a third motor 21 is fixedly installed on the end of the cross bar 20. A disc 22 is fixedly installed on the output end of the third motor 21, and a top plate 23 is detachably installed on the side wall of the disc 22. The top plate 23 can be replaced according to the type of thin floor to be processed, and the disc 22 plays a role in strengthening the top plate 23. At the same time, a scale data is provided on the outer ring part of the side wall surface of the disc 22 to facilitate manual observation of the rotation angle of the top plate 23.

[0042] Four groups of molding fixing components 24 are fixedly installed on the top surface and the bottom surface of the top plate 23. The four groups of molding fixing components 24 are all arranged in the outer area of ​​the top plate 23, and their positions are aligned with the outer area of ​​the thin floor embedding groove. The purpose of arranging the molding fixing components 24 on the top surface and the bottom surface of the top plate 23 is that when the molding fixing components 24 on one side are embedded with moldings, the molding fixing components 24 on the other side can be supplemented with moldings in cooperation with the external mechanism, thereby reducing the time for replacing moldings. The molding fixing components 24 include embedding bins 25 fixedly installed on the top surface and the bottom surface of the top plate 23. Two first telescopic structures 26 are fixedly installed on the side walls on both sides of the embedding bins 25. The ends of the two first telescopic structures 26 are fixedly installed with side plates 27 together. In this embodiment, the first telescopic structure 26 can be a telescopic rod, and its function is to perform telescopic movement through the control of the processing system. , driving the side plate 27 to move and then correcting the position of the inlay placed in the embedding bin 25, so that the inlay is placed correctly. Since the thin floor has a position deviation after being clamped and fixed, a plurality of hydraulic rods 28 are arranged at the inner bottom of the embedding bin 25, and the inlay is placed at the end of the hydraulic rod 28. The processing system drives the lifting rod 19 to rise or fall. When the lifting rod 19 moves, it drives the cross bar 20 to move. The movement of the cross bar 20 drives the third motor 21 to move. The movement of the third motor 21 drives the disc 22 to move. The movement of the disc 22 drives the top plate 23 to move. The movement of the top plate 23 drives the inlay fixing assembly 24 to move. Then, when the inlay fixing assembly 24 moves to contact with the top surface of the thin floor, the processing system drives the hydraulic rod 28 to operate. The hydraulic rod 28 pushes the inlay to be embedded in the groove of the thin floor, so that the outer area of ​​the groove in the thin floor is embedded with the inlay;

[0043] The surface of the thin floor is provided with four grooves extending from the center to the surroundings, and the outward area of ​​each groove is embedded with a fillet, the purpose of which is to isolate the internal environment of the modular all-steel floor from the external environment, thereby improving the corrosion resistance of the modular all-steel floor. Also, because the fixed structure of the modular all-steel floor is located in its central area, the setting of the fillet can effectively prevent the fixed structure from being corroded;

[0044] The two thin floors placed on the two mechanical arm assemblies 2 are matching floors, wherein a through hole 33 is set at the intersection of the grooves of one thin floor, and a sealing mechanism 34 is set at the intersection of the grooves of the other thin floor. The sealing mechanism 34 includes an insertion rod 35 fixedly installed at the intersection of the grooves of the thin floor, and a hot melt plate 36 is set at the end of the insertion rod 35. After the two thin floors are merged through the above-mentioned three types of clamping assembly 11 rotation process, the insertion rod 35 is inserted into the through hole 33, and the specifications of the insertion rod 35 and the through hole 33 are matched. The gap between the insertion rod 35 and the through hole 33 after merging can be ignored. This method can fix the combined all-steel floor after the two thin floors are merged;

[0045] The work frame 9 includes a conical structure 29 fixedly mounted on the output end of the second motor 8, a fourth motor 30 is fixedly mounted on the inner bottom of the conical structure 29, a second telescopic structure 31 is fixedly mounted on the output end of the fourth motor 30, an electric heating plate 32 is fixedly mounted on the end of the second telescopic structure 31, and the electric heating plate 32 is a prior art structure, which will not be described in detail here. The shape of the electric heating plate 32 matches the setting of the hot melt plate 36, and the processing system drives the second telescopic structure 31 to extend, and the extension of the second telescopic structure 31 drives the electric heating plate 32 to move until the electric heating plate 32 moves to contact the hot melt plate 36, at which time the processing system drives the electric heating plate 32 to heat and heat the hot melt plate 36, so that the hot melt plate 36 partially melts into a liquid medium, and fills part of the gap between the insertion rod 35 and the perforation 33, and after the preset heating time, the processing system drives the electric heating plate 32 to reset, and waits for the liquid medium to cool and solidify, so as to further reinforce the two thin floors and further seal and reinforce the internal environment of the combined all-steel floor;

[0046] The two mechanical arm assemblies 2 are arranged in the same structure to reduce the matching time of the thin floor;

[0047] A first storage box 38 and a second storage box 39 are arranged on one side of the base 1. The functions of the first storage box 38 and the second storage box 39 are inconsistent. The purpose of setting the two storage boxes is also to allow the anti-corrosion medium to be added without pausing during the spraying process. A first telescopic tube 40 is arranged on the first storage box 38 and is sealed with the pipeline of the automatic spraying arm 16. A second telescopic tube 41 is arranged on the second storage box 39 and is sealed with the pipeline of the automatic spraying arm 16. The anti-corrosion medium in the first storage box 38 and the second storage box 39 is transferred to the first telescopic tube 40 and the second telescopic tube 41 by a first pumping machine arranged in the first storage box 38 and the second storage box 39, and finally sprayed toward the surface of the thin floor through the automatic spraying arm 16, so that the anti-corrosion medium is coated on the surface of the thin floor, and the rack 10 is arranged in a grid shape, so that the anti-corrosion medium can be sprayed on all surfaces of the thin floor through the movement of the mechanical arm assembly 2, ensuring uniform spraying without omission;

[0048] Third telescopic tubes 42 are respectively extended from both sides of the first storage box 38. The third telescopic tubes 42 penetrate the second arm 7 and extend into the work frame 9, and the tube mouth of the third telescopic tube 42 faces the processing groove 37. After the two thin floors are merged, it is necessary to detect the connection between the middle plug rod 35 and the perforation 33. The detection method is to transfer the anti-corrosion medium in the first storage box 38 to the third telescopic tube 42 through the second pumping machine set in the first storage box 38, and then spray it to the processing groove 37, that is, the connection between the plug rod 35 and the perforation 33 through the tube mouth of the third telescopic tube 42. Liquid is continuously transported through the third telescopic tube 42 to check whether there is anti-corrosion medium entering the groove of the thin floor from the connection between the plug rod 35 and the perforation 33. If there is anti-corrosion medium entering the groove of the thin floor, it will flow out through the groove. This inspection process can be carried out manually or by supporting inspection equipment. The purpose is to confirm that the connection between the plug rod 35 and the perforation 33 is sealed to ensure that the formed combined all-steel floor is high in firmness.
