Example

[0023] Please refer to Figure 1-4 As shown, the utility model provides a technical solution: a special tooling platform for adjusting the roundness of the pressure steel pipe of a pumped storage power station;

[0024] A support column 7 is fixedly installed on the upper end of the base platform 1, and a boss 9 is integrally installed on the upper end of the support column 7. A steel ball 8 is snap-fitted and installed on the upper end of the support column 7. A tool support 4 is fixedly installed on the upper surface of the base platform 1, and an adjustment rail 5 is fixedly installed on the upper end of the tool support 4. The diameter adjustment seat 2 is divided into eight groups and arranged on the upper side of the base platform 1, and the position of the diameter adjustment seat 2 can be adjusted through the adjustment hole 6. The support column 7 is located at the center position of the eight groups of diameter adjustment seats 2, and the center of the circle of the support column 7 is on a vertical line with the center of the circle of the base platform 1; a jack 10 is fixedly installed on the outer end of the diameter adjustment seat 2, and a top head 11 is fixedly installed on the end of the jack 10, and an adjustment rail 5 is fixedly installed on the lower end of the diameter adjustment seat 2, and adjustment holes 6 are equidistantly provided at the inner end of the adjustment rail 5 to achieve circular adjustment of pressure steel pipes of different diameters, with high precision and easy use;

[0025] The inner end of the cross-shaped support 3 is fixedly installed with a mounting seat 12, and the surface of the mounting seat 12 is fixedly installed with an octagonal cap 13, and the inner end of the octagonal cap 13 is provided with a cylindrical groove 14, and the cylindrical groove 14 is engaged with the outer end of the boss 9. The inner end of the cross-shaped support 3 is threadedly connected with a threaded fastening rod 15, and the end of the threaded fastening rod 15 is fixedly installed with an end head top column 16. The cross-shaped support 3 is provided with eight groups, and all are installed on the upper end of the support column 7 through the mounting seat 12 and the octagonal cap 13. The lower end of the octagonal cap 13 is located on the upper end of the support column 7, and the lower surface of the octagonal cap 13 is fitted with the steel ball 8, which is flexible and convenient to use. After adjusting the circle, the cross-shaped support 3 can be hoisted and transferred together with the pressure steel pipe, so as to realize a stable and effective circle adjustment support, which is convenient for installation and disassembly.

[0026] Specific working principle:

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the special tooling platform for adjusting the diameter of the pressure steel pipe of the pumped storage power station is used, the diameter adjustment seat 2 is adjusted to a suitable adjustment position according to the diameter of the pressure steel pipe. When adjusting, the bolts on the diameter adjustment seat 2 are unscrewed, and then the diameter adjustment seat 2 is moved on the upper end of the adjustment rail 5. After the diameter adjustment seat 2 is moved to the desired position, it is fixed again using the adjustment hole 6, and the diameter adjustment seat 2 is fixed again using the bolts. The eight groups of diameter adjustment seats 2 are all adjusted equidistantly, and then the pressure steel pipe that needs to be adjusted is hoisted to the upper side of the adjustment rail 5 using the lifting equipment, so that the jack 10 and the top head 11 are covered on the inner side of the pressure steel pipe, and then the output end of the jack 10 on the diameter adjustment seat 2 drives the top head 11 to extend outward to perform the adjustment work, and then the threaded fastening rod 15 threadedly connected to the inner end of the M-shaped support 3 is rotated, and the threaded fastening rod 15 and the end head top column 16 are turned outward, so that the end head top column 16 is closely fitted to the inner surface of the steel pipe. The rounding of the penstock is facilitated by the octagonal cap 13 and the cylindrical groove 14. The mitre support 3 can be rotated on the outer end of the boss 9 through the octagonal cap 13. During the rotation, the steel ball 8 at the top of the support column 7 rotates, making the rotation more labor-saving. The eight groups of end head top columns 16 are all adjusted to fit closely with the penstock. After the rounding work is completed, the penstock can be transferred to the next process by means of the hoisting setting. When the penstock moves up and down for transfer, the octagonal cap 13 and the cylindrical groove 14 follow the penstock and separate from the boss 9 and move upward, so that the mitre support 3 continues to support the penstock and maintains the shape of the penstock. When the mitre support 3 needs to be removed, the threaded fastening rod 15 is rotated inwardly and the end head top column 16 is retracted to complete the disassembly. The above completes a series of operations of the special tooling platform for adjusting the rounding of the penstock of the pumped storage power station. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
