[0026] As Figures 1 to 7 shown, a tower crane base suitable for deep silt stratum, including installation base 1, still include: a plurality of first positioning pipe 2, a plurality of first positioning pipe 2 through setting on installation base 1, and top fixedly connected with first flange plate 201, a plurality of second positioning pipe 3, a plurality of second positioning pipe 3 are inserted in a plurality of first positioning pipe 2 respectively, and top fixedly connected with second flange plate 301, the bottom end of second positioning pipe 3 is symmetrically slidably inserted with two positioning claws 4, tower body 5, tower body 5 bottom fixedly installed with a plurality of third flange plate 501, third flange plate 501, second flange plate 301 and first flange plate 201 are fixed in the top of installation base 1 through positioning bolt, linkage assembly, linkage assembly is used in the process of second positioning pipe 3 inserting into first positioning pipe 2, and the two positioning claws 4 that move to the lower side of first positioning pipe 2 move, so that positioning claw 4 extends from the bottom end of first positioning pipe 2.

[0027] It should be understood that the installation base 1 can be cast in concrete in the pit foundation of the excavated stratum, and the first positioning pipe 2 can be used as a concrete cast by extending from the bottom of the installation base 1 to the deep stratum, thereby increasing the adhesion depth between the bottom end of the installation base 1 and the stratum, and facilitating the maintenance of the stability of the installation base 1 to achieve the penetration through the thick silt layer into the deep stratum;

[0028] By inserting the second positioning pipe 3 into the first positioning pipe 2, the length is further extended, and the second positioning pipe 3 is inserted into the first positioning pipe 2. During the insertion of the second positioning pipe 3 into the first positioning pipe 2, the linkage assembly moves to the two positioning claws 4 below the first positioning pipe 2 to move, so that the positioning claws 4 extend from the bottom end of the first positioning pipe 2, and the positioning claws 4 move transversely and are inserted into the deep stratum for further adhesion. While extending deeper into the stratum, the deep stratum is further adhered, which is beneficial to further ensure the stability of the installation base 1, and further facilitates the stable support of the tower body 5 installed on the installation base 1.

[0029] Specifically, the first flange plate 201 is attached to the top surface of the installation base 1, the second flange plate 301 is attached to the top surface of the first flange plate 201, and the third flange plate 501 is attached to the top surface of the second flange plate 301.

[0030] As shown in Figure 1 and Figure 2 , specifically, the positioning bolt includes a threaded rod 16 and a nut 17, the positioning bolt is fixedly connected to the top surface of the installation base 1, and penetrates the first flange plate 201, the second flange plate 301 and the third flange plate 501 in sequence, the nut 17 is threadedly connected to the surface of the threaded rod 16, and the nut 17 presses the third flange plate 501.

[0031] Specifically, the installation base 1 has an insertion port 18 corresponding to the position of the first positioning pipe 2, and the threaded rod 16 is distributed at the edge of the insertion port 18.

[0032] As shown in Figure 3 , Figure 6 and Figure 7As shown, in an optional embodiment of this utility model, the linkage component includes: two insertion slots 7, which are symmetrically opened at the bottom end of the second positioning tube 3, and two positioning claws 4 are slidably inserted into the insertion slots 7; a moving part 8, which has a connecting slot 9 at its bottom end, and two symmetrically arranged inclined slots 10 are opened in the connecting slot 9, and a driving pin 11 is slidably arranged in each of the two inclined slots 10, and the two driving pins 11 are respectively fixedly connected to the two positioning claws 4; a clearance slot 12, which is opened through the side wall of the second positioning tube 3, and a hanging block 13 is slidably arranged inside it, and the hanging block 13 is fixedly connected to the top of the moving part 8; and a limiting slot 14, which is opened on the inner wall of the first positioning tube 2, and the hanging block 13 is slidably arranged in the limiting slot 14.

[0033] It should be understood that during the process of the bottom end of the second positioning tube 3 being inserted into and out of the first positioning tube 2, the hook block 13 will slide into the limiting groove 14 until the hook block 13 hooks onto the bottom end of the upper limit groove 14. When the second positioning tube 3 continues to move, the hook block 13 will maintain the position of the moving part 8. The second positioning tube 3 drives the positioning claw 4 to move relative to the moving part 8. Under the action of the inclined groove 10, the driving pin 11 will drive the positioning claw 4 to move to the outside of the second positioning tube 3 until the second positioning tube 3 is completely inserted into the first positioning tube 2. Then, the two positioning claws 4 complete the insertion into the formation, increase new attachment points, and generate more connection points with the formation.

[0034] Specifically, the limiting groove 14 extends to the top of the first positioning tube 2. It should be understood that by extending the limiting groove 14 to the top of the first positioning tube 2, it docks with the hanging block 13 during the process of inserting the second positioning tube 3 into the first positioning tube 2.

[0035] like Figure 3 As shown in the preferred embodiment of this utility model, a return spring 15 is fixedly connected between the movable member 8 and the inner bottom end of the second positioning tube 3. By setting the return spring 15, the position of the movable member 8 can always be supported when the first positioning tube 2 is inserted into the second positioning tube 3, so that the two positioning claws 4 are limited in the insertion groove 7, avoiding any obstruction to the insertion process when the second positioning tube 3 is inserted into the first positioning tube 2.

[0036] like Figure 1 , Figure 3 and Figure 7 As shown in the preferred embodiment of this utility model, the bottom of the second positioning tube 3 has a tapered structure 19. By setting the tapered structure 19, its cross-sectional area gradually increases during the insertion process, which helps to reduce friction and resistance during insertion and makes it easier to insert the bottom end of the second positioning tube 3 into the stratum.

[0037] like Figure 4 andFigure 5 As shown, as the preferred embodiment of the utility model, the top of the second positioning pipe 3 is fixedly connected with the plug-in block 20, and the bottom of the third flange plate 501 is provided with the butt joint 6 matched with the plug-in block 20. It should be understood that by setting the plug-in block 20 and the butt joint 6, the butt joint between the second flange plate 301 and the third flange plate 501 is formed, the support limiting of the second positioning pipe 3 to the transverse direction of the tower body 5 is formed, and the transverse cutting force on the threaded rod 16 is reduced.

[0038] The above is only the preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
