[0026] The following further details the features of the present utility model and other related features through embodiments for the understanding of those skilled in the same industry:

[0027] Refer to Figures 1-4 , and a preferred embodiment of a pile stabilizing platform of the present utility model that can adapt to different pile diameters is proposed:

[0028] A pile stabilizing platform that can adapt to different pile diameters includes a platform main body 1, a positioning collar 2 is installed on the platform main body 1, the positioning collar 2 is provided with a pile hole 21 for the foundation pile to penetrate through, at least two clamping mechanisms 3 are evenly distributed around the pile hole 21, the clamping mechanism 3 includes a connection seat 4 arranged on the positioning collar 2 and an abutting block 31 connected to the connection seat 4, the connection seat 4 is provided with a connection hole 431, a fixing nut 41 is arranged at the connection hole 431, one side of the abutting block 31 is provided with an arc surface 311 that fits the foundation pile, the other side of the abutting block 31 is connected with an adjusting screw 32, and the fixing nut 41 is used for threadedly connecting with the adjusting screw 32 and adjusting the distance between the arc surface 311 and the foundation pile, so as to achieve stable clamping of different diameters, and the operation is simple. Moreover, the clamping mechanism 3 can be adjusted to adapt to different pile diameters without replacing other sized clamping mechanisms 3, thereby reducing the cost of the pile stabilizing platform.

[0029] As Figure 2 shown, one end face of the fixing nut 41 extends outward to form an abutting surface 411, and the abutting surface 411 is fixedly connected to the connection seat 4 through a fixing screw 412. When the adjusting screw 32 rotates, since the connection seat 4 is fixedly connected to the fixing nut 41, the fixing nut 41 will not rotate with the adjusting screw 32.

[0030] As Figure 3As shown in the figure, one end of the adjusting screw rod 32 is provided with a nut 321 and a flat head 322 located behind the nut 321. A clamping groove 312 is formed by downward depression at the top of the abutting block 31. One end of the abutting block 31 connected to the adjusting screw rod 32 is provided with a through hole 313 communicating with the clamping groove 312. The aperture of the through hole 313 is smaller than the diameter and width of the nut 321 and the flat head 322. The nut 321 is located in the clamping groove 312. The adjusting screw rod 32 passes through the through hole 313, and the flat head 322 is located outside the abutting block 31, so that when the adjusting screw rod 32 rotates, it will not drive the abutting block 31 to rotate together, but only drive the abutting block 31 to move linearly along the direction of the adjusting screw rod 32, and the transmission mode is more reasonable.

[0031] The abutting block 31 is provided with a guide rod 33 parallel to the adjusting screw rod 32, and the connecting seat 4 is provided with a guide hole 432 for the guide rod 33 to pass through. During the process of the adjusting screw rod 32 rotating to drive the abutting block 31 to move, the cooperation of the guide rod 33 and the guide hole 432 enables the abutting block 31 to move more stably.

[0032] As Figure 4 shown in the figure, the connecting seat 4 includes a first connecting plate 43 perpendicular to the adjusting screw rod 32. Fixing plates 42 are provided at both ends of the first connecting plate 43, and the fixing plates 42 are perpendicular to the first connecting plate 43. The first connecting plate 43 is provided with a connecting hole 431 and a guide hole 432. The fixing plates 42 can share the pressure borne by the first connecting plate 43, making the first connecting plate 43 connected to the abutting block 31 more stable. One end of the fixing plate 42 close to the abutting block 31 is provided with a second connecting plate 44, and the fixing plate 42 and the second connecting plate 44 are perpendicular to form an L-shaped structure. The second connecting plate 44 is also provided with a guide hole 432, and the guide rod 33 passes through the two guide holes 432, making the guide rod 33 more stable during the moving process.

[0033] The platform main body 1 includes an installation plane 11 and a plurality of positioning piles 12. A plurality of sleeves 13 are uniformly arranged on the outer periphery of the installation plane 11, and the positioning piles 12 penetrate through the sleeves 13 and are fixedly connected to the sleeves 13.

[0034] As Figure 1 shown in the figure, the installation plane 11 is a rectangular structure, and sleeves 13 are provided at all four corners of the installation plane 11. The stable pile platform also includes a bolt 14 and a sling 15. The bolt 14 includes a rod portion 141. One end of the rod portion 141 is provided with a convex portion 142. The other end of the rod portion 141 sequentially passes through the sling 15, the sleeve 13 and is connected to the positioning pile 12. The positioning pile 12 is provided with a lifting lug 121 for connecting the sling 15. The sleeve 13 of the stable pile platform is connected to the positioning pile 12 through the bolt 14, and the bolt 14 is connected to the lifting lug 121 of the positioning pile 12 through the sling 15, making the connection between the sleeve 13 and the positioning pile 12 more stable, thereby improving the stability of the stable pile platform.

[0035] The installation plane 11 is provided with a plurality of first screw holes, and the positioning collar 2 is connected to the first screw holes through installation screws, so that the positioning collar 2 is detachably installed on the top of the installation plane 11. When it is necessary to clamp a foundation pile thicker than the pile hole 21 of the original positioning collar 2, the original positioning collar 2 can be removed and replaced with a positioning collar 2 with a larger pile hole 21, and the clamping mechanism 3 on the original positioning collar 2 can be detachably installed on another positioning collar 2 for repeated use, reducing the construction cost of pile driving.

[0036] The pile stabilizing platform adapts to foundation piles with smaller diameters by adjusting the clamping mechanism 3, and adapts to foundation piles with larger diameters by replacing the positioning collar 2 and then adjusting the clamping mechanism 3 to clamp the foundation pile, so that the pile stabilizing platform can meet the pile driving construction of foundation piles with different diameters.

[0037] A floating plate 17 is provided on the outer periphery of the casing 13 for adjusting the bottom force and bottom depth of the pile stabilizing platform. The floating plate 17 is connected to the bottom of the installation plane 11 through a support rod 16, and a triangular support structure is formed among the floating plate 17, the installation plane 11 and the casing 13, so that the connection between the installation plane 11 and the casing 13 is stable.

[0038] The construction process of the pile stabilizing platform of the present utility model is as follows: First, the installation plane 11 is lifted by a crane ship to a designated position at sea, and then the positioning pile 12 is lifted and inserted into the casing 13, and the positioning pile 12 is fixed to the casing 13 through a pin 14 and a sling 15. Then, the pile stabilizing platform is sunk and fixed, so that the pile stabilizing platform completes the seabed pounding. Then, the foundation pile is lifted to the pile stabilizing platform and inserted into the pile hole 21, and then the abutting block 31 is clamped to the foundation pile by rotating the adjusting screw 32 to realize the positioning of the foundation pile. Then, the foundation pile is smoothly sunk to a predetermined depth by means of hammering, vibrating the foundation pile, etc. Finally, by rotating the adjusting screw 32, the abutting block 31 is released from the foundation pile, and the pile stabilizing platform is removed.

[0039] The preferred embodiments do not limit the patent scope of the present utility model. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
