Detailed Description
The present invention will be further described with reference to the following embodiments and accompanying drawings.
As shown in figure 1, the connecting structure of the steel pipe column and the tool pipe between different diameters comprises a flange connecting reducing plate 1, a steel pipe column 2 with different diameters and a tool pipe 3.
The steel pipe column 2 has a smaller diameter than the tool pipe 3. The connecting ends of the steel pipe column 2 and the tool pipe 3 are respectively provided with a steel pipe column flange 21 and a tool pipe flange 31, the steel pipe column flange 21 and the tool pipe flange 31 are respectively provided with a steel pipe column flange bolt hole 22 and a tool pipe flange bolt hole 32, and in addition, the steel pipe column flange 21 and the tool pipe flange 31 are also provided with reinforcing ribs 23 and 33 for reinforcing the structural strength.
The flange connection reducing plate 1 is of a circular structure made of metal plates, two circles of connecting holes corresponding to the steel pipe column flange bolt holes 22 and the tool pipe flange bolt holes 32 are arranged on the flange connection reducing plate 1, and an inner ring and an outer ring are arranged between the two circles of connecting holes, wherein the connecting holes corresponding to the steel pipe column flange bolt holes 22 are inner ring connecting holes 11, and the connecting holes corresponding to the tool pipe flange bolt holes 32 are outer ring connecting holes 12.
The steel pipe column 2 and the tool pipe 3 are connected together by flange connection reducer plates 1. Specifically, the flange connection reducing plate 1 and the steel pipe column 2 are firmly connected through the high-strength bolts 4 through the inner ring connecting holes 11 and the steel pipe column flange bolt holes 22, and the steel pipe column 2 is located on the lower side of the flange connection reducing plate 1.
