[0002] The fixed-diameter pile stabilizing platform usually has a plurality of pile holes for the foundation piles to pass through, and the positions of the lower pile holes are fixed, which will cause that during on-site construction, the sinking position of the foundation piles cannot be changed, and it is necessary to replace another pile stabilizing platform to fix the foundation piles, increasing the cost of the pile driving equipment.

[0003] For example, Chinese Patent with publication number CN117605030A discloses a pile stabilizing platform for the construction of an underwater four-pile jacket foundation of an offshore wind farm, including a foundation platform and a hammer pressing platform. The foundation platform includes a top platform and a sinking prevention plate. Auxiliary cylinders are fixedly connected between the four corners of the top platform and the four corners of the sinking prevention plate. A fixing bracket is fixedly connected between the four auxiliary cylinders. The fixing bracket is located between the top platform and the sinking prevention plate. A positioning frame is fixedly connected to the outer wall of the top platform at the connection with the four auxiliary cylinders, and a guiding cylinder matching the positioning frame is fixedly connected to the outer wall of the fixing bracket. The position of the guiding cylinder of the above pile stabilizing platform is fixed, resulting in the inability to flexibly adjust the sinking position of the foundation piles. In view of this, the utility model provides a pile stabilizing platform with adjustable pile spacing to solve the above problems. Content of the Utility Model

[0004] In order to overcome the above technical deficiencies, the utility model provides a pile stabilizing platform, which can realize the adjustment of the sinking position between the foundation piles by adjusting the position of the circular pile holes.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

An eccentric collar is detachably connected to the eccentric through hole. The eccentric collar includes a connecting plate, and the connecting plate is provided with a circular pile hole for passing through the foundation pile. The center of the circular pile hole deviates from the center of the connecting plate, and a clamping mechanism for clamping the foundation pile is arranged on the connecting plate.

[0010] Preferably, the eccentric through-hole is formed by the intersection of at least two round holes. The diameter of the round hole closer to the center of the platform body is smaller, and the centers of all the round holes of the same eccentric through-hole and the center of the platform body are on the same straight line.

[0011] Preferably, a boss is arranged around the edge of the eccentric through-hole at the bottom of the platform body, and the outer surface of the round tube abuts against the inner surface of the boss after passing through the eccentric through-hole.

[0012] Preferably, a second reinforcing rib is arranged between the outer surface of the boss and the bottom of the platform body.

[0013] Preferably, the wall thickness of the round tube is different, and the wall thickness of the round tube farther away from the edge of the connecting plate is greater than the thickness of the round tube closer to the edge of the connecting plate.

[0014] Preferably, the connecting plate and the platform body are detachably connected by bolts, and the boss is provided with a first threaded hole for connecting with the bolts.

[0015] Preferably, at least two clamping mechanisms are uniformly arranged on the eccentric collar. The clamping mechanism includes an abutting block and a fixing plate arranged on the eccentric collar. One end of the abutting block is provided with an arc surface that fits the foundation pile. The other end of the abutting block is connected with a fixing screw. The fixing plate is provided with a connecting hole, and an adjusting nut is arranged at the connecting hole. The adjusting nut is used for threadedly connecting with the fixing screw and adjusting the distance between the arc surface and the foundation pile.

[0027] 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:

[0028] Refer to Figures 1-6 , and a specific embodiment of the pile stabilizing platform with adjustable pile distance of the present utility model is proposed:

[0029] An adjustable pile-spacing pile-stabilizing platform, including a platform main body 1. A plurality of eccentric through-holes 11 are circumferentially arranged around the center of the platform main body 1, and an eccentric collar 2 is detachably connected to the eccentric through-holes 11. The eccentric collar 2 includes a connecting plate 21, and the connecting plate 21 is provided with a circular pile hole 22 for passing through a foundation pile. The center of the circular pile hole 22 deviates from the center of the connecting plate 21. By rotating the eccentric collar 2 on the platform main body 1, the relative positions of the respective circular pile holes 22 can be adjusted.

[0030] A clamping mechanism 3 for clamping the foundation pile is provided on the connecting plate 21 to prevent the foundation pile from moving or tilting during the pile driving process.

[0031] As Figure 1 shown, the eccentric collar 2 includes a circular tube 23, the passage of the circular tube 23 is the circular pile hole 22, the connecting plate 21 is connected to the outer surface of the circular tube 23, and the outer diameter of the circular tube 23 is smaller than the aperture of the eccentric through-hole 11. A first reinforcing rib 24 is provided between the outer surface of the circular tube 23 and the connecting plate 21 to strengthen the connection strength between the circular tube 23 and the connecting plate 21, and can avoid deformation caused by excessive stress during the pile driving process. Specifically, in this embodiment, the connecting plate 21 is a circular plate, and in other embodiments, the connecting plate can be other flat plates with regular shapes.

[0032] Since the distance between foundation piles with smaller diameters is usually smaller, while the distance between foundation piles with larger diameters is usually larger. Therefore, in the present utility model, the aperture of the eccentric through-hole 11 near the center of the platform main body 1 is smaller than the aperture of the eccentric through-hole 11 far from the center of the platform main body 1. A boss 13 is arranged around the edge of the eccentric through-hole 11 at the bottom of the platform main body 1. When positioning foundation piles with smaller diameters, the eccentric collar 2 is installed close to the center of the platform main body 1, so that the distance between the foundation piles is smaller. Moreover, the aperture of the eccentric through-hole 11 near the center of the platform main body 1 is also smaller, which is convenient for the boss 13 at the edge of the eccentric through-hole 11 to abut against the outer surface of the circular tube 23, so that the platform main body 1 can support the circular tube 23 through the boss 13 during the pile driving process, making the construction process stable. Similarly, when positioning foundation piles with larger diameters, the eccentric collar 2 is installed far from the center of the platform main body 1, so that the distance between the foundation piles is larger, and the aperture of the eccentric through-hole 11 far from the center of the platform main body 1 is also larger, which is convenient for the boss 13 at the edge of the eccentric through-hole 11 to abut against the outer surface of the circular tube 23.

[0033] As Figure 4 shown, the eccentric through-hole 11 is formed by the intersection of two circular holes. The closer the circular hole is to the center of the platform main body 1, the smaller its aperture. The centers of all the circular holes of the same eccentric through-hole 11 and the center of the platform main body 1 are on the same straight line, ensuring that the eccentric through-holes 11 are evenly arranged circumferentially around the center of the platform main body 1.

[0034] As Figure 2As shown, a second reinforcing rib 14 is provided between the outer surface of the boss 13 and the bottom of the platform main body 1 to strengthen the connection strength between the boss 13 and the platform main body 1, enabling the boss 13 to better support the circular tube 23 and the foundation pile during the pile sinking process.

[0035] As Figure 3 shown, the wall thickness of the circular tube 23 is different, and the wall thickness of the circular tube 23 farther away from the edge of the connecting plate 21 is greater than the thickness of the circular tube 23 closer to the edge of the connecting plate 21. The thicker wall is more likely to abut against the boss 13.

[0036] The connecting plate 21 and the platform main body 1 are detachably connected by bolts 15. The boss 13 is provided with a first threaded hole 131 for connecting with the bolt 15, further enabling the eccentric collar 2 to be tightly connected to the platform main body 1 and reducing the possibility of loosening and shaking.

[0037] At least two clamping mechanisms 3 are evenly arranged on the eccentric collar 2. As Figures 5-6 shown, the clamping mechanism 3 includes an abutting block 31 and a fixing plate 4 arranged on the eccentric collar 2. One end of the abutting block 31 is provided with an arc surface that fits the foundation pile. The other end of the abutting block 31 is connected with a fixing screw 32. The fixing plate 4 is provided with a connection hole, and an adjusting nut 33 is arranged at the connection hole. The adjusting nut 33 is used for threadedly connecting with the fixing screw 32 and adjusting the distance between the arc surface and the foundation pile. One end surface of the adjusting nut 33 extends outward to form an abutting surface, and the abutting surface is connected to the fixing plate 4 by a fixing screw 34. One end of the fixing screw 32 is provided with a nut 321 and a flat head 322 behind the nut 321. A clamping groove 311 is formed by downward depression at the top of the abutting block 31. One end of the abutting block 31 connected to the fixing screw 32 is provided with a through hole 312 communicating with the clamping groove 311. The aperture of the through hole 312 is smaller than the width of the nut 321 and the flat head 322. The nut 321 is located in the clamping groove 311, and the fixing screw 32 passes through the through hole 312, and the flat head 322 is located outside the abutting block 31. When the fixing screw 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 fixing screw 32.

[0038] The process of fixing the foundation pile of the pile stabilizing platform is as follows: When the diameter of the foundation pile to be fixed is small, place the eccentric collar 2 in the circular hole near the center of the platform main body 1, and measure whether the distance between two adjacent circular pile holes 22 meets the requirements for pile driving. If there is a certain deviation, the eccentric collar 2 can be rotated to finely adjust the distance between the circular pile holes 22, and make the outer surface of the round tube 23 abut against the inner surface of the boss 13. Then, connect the connecting plate 21, the platform main body 1, and the boss 13 in sequence through bolts, then pass the foundation pile through the circular pile holes 22, and finally fix the foundation pile through the clamping mechanism 3. When the diameter of the foundation pile to be fixed is large, place the eccentric collar 2 in the circular hole far from the center of the platform main body 1, and repeat the above fixing operation. The diameter of the foundation pile can be smaller than the diameter of the circular pile holes 22 because the clamping mechanism 3 can achieve the fixation of the foundation pile by abutting against the outer surface of the foundation pile, enabling the pile stabilizing platform to meet the guiding and positioning of foundation piles with different diameters, thereby reducing the cost of pile stabilizing construction equipment.
