[0026] like Figure 1-Figure 4 As shown, the utility model discloses a top tooling connection device for a standard section supporting tower, including a top tooling 1, a tooling connection device 2 and a tower crane standard section 3. The top tooling 1 is a frame structure at the top of a temporary support system. The tooling connection device 2 is used to connect the top tooling 1 with the tower crane standard section 3, and includes a top steel plate 21, a bolt sleeve 22, a steel pipe 23, a nut 24 and a screw 25 with a nut. The top steel plate 21 is used to connect with the top tooling 1, and its connection form can be but not limited to welding, bolting, connection plate connection and the like. The steel pipe 23 is welded to the bottom surface of the top steel plate 21, and the bolt sleeve 22 is connected to the steel pipe 23.

[0027] The tower crane standard section 3 comprises a tower crane standard section bolt sleeve 31 and a tower crane standard section column 32 . The tower crane standard section bolt sleeve 31 and the tower crane standard section column 32 are already welded and connected when the tower crane standard section 3 leaves the factory.

[0028] The steel pipe 23 needs to be aligned with the tower crane standard section column 32, and there should be no misalignment. The bolt sleeve 22 needs to be aligned with the tower crane standard section bolt sleeve 31, otherwise the screw rod 25 with the nut cannot be inserted smoothly. Before installation, the steel pipe 23 needs to be welded to the bolt sleeve 22, and the steel pipe 23 is welded to the top steel plate 21. The screw rod 25 with the nut has been installed in the bolt sleeve 22, and the nut 24 and the top tooling 1 have not been installed. During installation, the screw rod 25 with the nut needs to be inserted into the tower crane standard section bolt sleeve 31 and the steel pipe 23 needs to be aligned with the tower crane standard section column 32. After the bolt sleeve 22 is aligned with the tower crane standard section bolt sleeve 31, the nut 24 is tightened, and then the top tooling 1 is connected and fixed to the top steel plate 21.

[0029] Among them, the steel pipe 23 and the tower crane standard section column 32 need to have the same outer dimensions, and the cross-sectional shapes of the steel pipe 23 and the tower crane standard section column 32 may include but are not limited to rectangle, square, trapezoid, parallelogram, triangle, polygon with more than four sides, circle, ellipse, etc.

[0030] To ensure safety, the number of the bolt sleeve 22, the nut 24, and the screw rod 25 with a nut is at least two, which can be increased or decreased according to the situation. The number of the steel pipe 23 and the top steel plate 21 is one.

[0031] The projection area of ​​the top steel plate 21 needs to be larger than the sum of the projection areas of the steel pipe 23 and the bolt sleeve 22. The projection area of ​​the top steel plate 21 needs to be larger than the projection area of ​​the connection of the top tooling 1. The cross-sectional shape of the top steel plate 21 may include but is not limited to a rectangle, square, trapezoid, parallelogram, triangle, polygon with more than four sides, circle, ellipse, etc.

[0032] The bolt sleeve 22 has a suitable opening, and the diameter of the hole is slightly larger than the diameter of the screw rod 25 with the nut.

[0033] The installation method is as follows:

[0034] Step 1: First, weld the steel pipe 23 to the bolt sleeve 22, and then weld the steel pipe 23 to the top steel plate 21. The screw rod 25 with the nut has been installed in the bolt sleeve 22, and the nut 24 and the top tooling 1 have not been installed.

[0035] Step 2: Insert the screw rod 25 with the nut into the tower crane standard section bolt sleeve 31.

[0036] Step 3: Set the nut 24 on the end of the screw rod 25 with a nut and tighten it.

[0037] Step 4: Install the top tooling 1 on the top steel plate 21 . The top tooling 1 can be welded and fixed to the top steel plate 21 .

[0038] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
