[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] Embodiment 1

[0025] like Figures 1 to 4 As shown, the tower crane foundation deviation correction conversion joint device includes a foundation frame 1 located in the middle, and a plurality of adjustment support points are arranged on the foundation frame 1. The adjustment support points are located on the bottom surface of the foundation frame 1 and a lower support 2 is arranged downwardly, and the adjustment support points are located on the top surface of the foundation frame 1 and an upper support 3 is arranged upwardly. The corresponding lower support 2 and upper support 3 on each adjustment support point are connected through an adjustment component. The adjustment component includes an adjustment bolt 4 that passes through the lower support 2, the foundation frame 1 and the upper support 3. The adjustment end of the adjustment bolt 4 is sequentially sleeved with at least one gasket and an adjustment nut 5. The gasket is clamped between the foundation frame 1 and the lower support 2 / upper support 3. The adjustment nut 5 presses the gasket and forms a threaded locking fit with the adjustment bolt 4.

[0026] like Figure 1 and 3 As shown, the basic frame 1 includes a rectangular outer frame 1a, and support beams 1b are fixedly connected between opposite corners in the rectangular outer frame 1a, and the corners of the rectangular outer frame 1a are set as adjustment support points. The rectangular outer frame 1a matches the shape characteristics of the embedded legs and the foundation section, and the four right-angled corners of the rectangular outer frame 1a are used as adjustment support points, which is conducive to the balanced bearing of the tower. At the same time, the strength of the rectangular outer frame 1a is improved by the crossed support beams 1b to prevent it from being deformed under pressure.

[0027] like Figures 1 to 3As shown, a plurality of bolt holes are opened on the corners of the rectangular outer frame 1a, a plurality of lower mounting holes are opened on the lower support 2, and a plurality of upper mounting holes are opened on the upper support 3. The lower mounting holes, bolt holes, and upper mounting holes are connected in sequence to form a straight assembly hole. Only when the lower mounting holes, bolt holes, and upper mounting holes are connected along the same straight line can the adjusting bolt 4 be passed through for connection.

[0028] The lower support 2 comprises a lower base plate, the bottom surface of which is provided with lower legs protruding downward, and a plurality of lower mounting holes are opened on the lower base plate, and the plurality of lower mounting holes are evenly arranged around the circumference of the lower legs. The lower base plate is used to realize the installation with the rectangular outer frame 1a, and the lower legs are used to provide the support height.

[0029] A lower mounting assembly for connecting the embedded leg is arranged on the lower leg, and the lower mounting assembly includes a mounting bolt 6 and a mounting nut 7 .

[0030] The upper support 3 includes an upper base plate, the top surface of which is provided with an upper leg protruding upward, and a plurality of upper mounting holes are opened on the upper base plate, and the plurality of upper mounting holes are evenly arranged around the circumference of the upper leg. The upper base plate is used to realize the installation with the rectangular outer frame 1a, and the upper leg is used to provide the support height.

[0031] like Figure 4 As shown, an upper mounting assembly for connecting the base section is provided on the upper leg, and the upper mounting assembly includes a pin shaft 1 8, a pin shaft 2 9 and a pin 10.

[0032] The tower crane foundation deviation correction conversion device works in the following ways:

[0033] The conversion joint device is installed between the embedded leg and the foundation joint. First, it is firmly connected to the embedded leg through the lower mounting assembly on the lower leg; then the foundation level is remeasured and recorded. If the foundation level deviation exceeds the specification during the level test, the height difference of each upper support 3 position is adjusted by adding or reducing gaskets until the overall upper support 3 reaches the required level range; then it is firmly connected to the foundation joint through the upper mounting assembly of the upper leg.

[0034] For bolt connection of conversion joint, if the bolt hole of the gasket cannot be installed with bolt 6 due to diagonal deviation, the bolt hole can be properly polished to ensure normal connection of the bolt. Do not use gas cutting or other methods to expand the hole. According to feedback from practical applications, each foot is installed with 6 M39-8.8 grade bolts, and the bolt preload force is required to reach 437KN. This can be achieved by using tools such as torque wrenches to meet the corresponding numerical requirements. During the preload process, tighten in a diagonal preload sequence to ensure that the bolts are evenly stressed. Anti-falling measures for gaskets, this requires ensuring that the bolts pass through the bolt holes of each gasket and are tightened in place before acceptance inspection. The connecting bolts of the conversion joints require the manufacturer to provide connecting bolts from the same batch.
