When the pile stabilization platform is lowered to the designed elevation position, the lowering is stopped, the claws on the two pairs of pile grippers are tightened, so that the pile stabilization platform and the two front pile legs of the self-elevating platform ship are fixed, and the horizontal telescopic mechanism is controlled according to the driving position of the engineering pile, so that the four pile driving guide sleeves are located at the driving position of the engineering pile, and the engineering pile is hoisted into the pile driving guide sleeve, and the pile sinking operation is carried out by the pile driver on the self-elevating platform ship.

A group of limit arms 2 are welded on the articulated shaft 11, and the limit arms 2 are arranged in parallel, and the end of the limit arm 2 away from the articulated shaft 11 is used to abut against the pile body. A driving assembly 3 is installed on the fixed seat 1, and the driving assembly 3 is used to drive the articulated shaft 11 to rotate. A support assembly 4 is installed on the fixed seat 1, and the support assembly 4 is used to support the limit arm 2. A linkage assembly 5 is installed between the support assembly 4 and the drive assembly 3, and the linkage assembly 5 is used to make the support assembly 4 and the drive assembly 3 move synchronously. Multiple fixed seats 1 are installed on the inner wall of the piling guide sleeve, so that the ends of the limit arms 2 away from the articulated shaft 11 are all facing the center of the piling guide sleeve. The driving assembly 3 drives the articulated shaft 11 to rotate, and the articulated shaft 11 drives the limiting arm 2 to rotate. The supporting assembly 4 moves synchronously under the action of the linkage assembly 5 to support the limiting arm 2, so that a passage for the pile body to be inserted is formed between the end of the limiting arm 2 away from the articulated shaft 11, so as to facilitate the adjustment of the distance between the end of the limiting arm 2 away from the articulated shaft 11 according to the pile diameter. When the pile body is inserted between the limiting arms 2, the end of the limiting arm 2 away from the articulated shaft 11 abuts against the outer wall of the pile body, achieving the effect of limiting and guiding the pile body, facilitating the limiting of pile bodies with different pile diameters, and expanding the application range of the pile driving guide sleeve.

[0040] Reference Figures 1 to 3 The limiting wheel 21 is rotatably arranged between the limiting arms 2, and the outer wall of the limiting wheel 21 is wrapped with a rubber abutment layer 22, and the abutment layer 22 is used to abut against the pile body. The limiting wheel 21 reduces the friction between the limiting arm 2 and the pile body, and the abutment layer 22 reduces the scratches between the limiting wheel 21 and the pile body.

A support groove 441 is provided on the limit arm 2, and the support block 44 is slidably arranged in the support groove 441. When the driving assembly 3 drives the limit arm 2 to rotate, the limit arm 2 drives the support block 44 to rotate, and the linkage assembly 5 drives the support head 42 to move along the support cylinder 41, so that the support head 42 drives the support rod 43 to move, and the support rod 43 drives the support block 44 to move, and the support block 44 moves along the support groove 441 under the action of the limit arm 2 and the support rod 43. When the limit arm 2 stops rotating, the support head 42 stops moving, so that the support block 44 supports the limit arm 2, making it difficult for the limit arm 2 to swing.
