Necessary gaps and chamfers are left in the welding area between the placing plate and the first reinforcing rib 7 to reduce deformation caused by welding and ensure the structural accuracy. The third placing plate 51 and the second reinforcing rib 8 are welded together to reinforce the strength of the guiding column and prevent it from tilting during the single-point turntable installation. The shape of the third placing plate 51 is generally oval, saving materials as much as possible while ensuring strength and being convenient for processing. Necessary gaps and chamfers are left in the welding area between the third placing plate 51 and the first reinforcing rib 7 to reduce deformation caused by welding and ensure the structural accuracy.

[0037] Further, as Figures 1 to 6 shown, the distance between the first contact part 35 and the top of the support column 1 is 0.5 - 0.6 m, as the distance D1 shown in Figure 2 , and the distance between the second contact part 54 and the top of the support column 1 is 0.4 - 0.5 m, as the distance D1 shown in Figure 5 . This is convenient for the first support part 3 and the first limiting part 4 to be aligned and inserted first. The first limiting part 4 rotates around the axis of the first support part 3 to align the second support part 5 and the second limiting part 6, and finally the first limiting part 4 is completely inserted into the first support part 3, and the second insertion part is inserted into the second support part 5.

[0038] The installation process of the pile foundation fixed single-point installation connection guiding device in the present utility model is as follows:

[0039] During the construction process of the rotation platform 2 and the support column 1 being joined together, first suspend the rotation platform 2 above the support column 1 and slowly lower it until the first contact part 35 is inserted into the first bell mouth 43. When it is continuously inserted to the maintaining part 34, use the maintaining part 34 as the rotation axis to restrict the downward movement of the rotation platform 2. Adjust the position and attitude of the pile foundation fixed single-point installation connection guiding device. With the maintaining part 34 as the central axis, rotate around the central axis of the maintaining part 34 so that the second insertion part is aligned with the second bell mouth 63. The rotation platform 2 continues to move downward, the first limiting part 4 is inserted into the first supporting part 3, and the second limiting part 6 is inserted into the second supporting part 5. After the rotation platform 2 and the support column 1 are completely inserted and installed, perform welding and fixation. After the overall welding is stable, the protruding part structure of the pile foundation fixed single-point installation connection guiding device can be cut off to increase the working space on the passage. This pile foundation fixed single-point installation connection guiding device can be used to confirm the orientations of the support column 1 and the rotation platform 2 during the installation of the single-point system, enabling the corresponding parts of the two structures to be aligned smoothly, ensuring accurate structural connection positioning, reducing system vibration and structural deformation. The design is economical and practical, improving the safety and reliability of the single-point system installation and the operation efficiency.
