Detailed implementation manners

[0025] The technical solutions of the present utility model will be further described below, but the scope of protection claimed is not limited thereto.

[0026] As Figures 1 to 7 shown.

[0027] A pile turning device for pipe piles in the present application is used in combination with a lifting rope to connect both ends of the pipe pile during operation, and includes:

[0028] A turning assembly for placing the pipe pile and a support assembly rotatably connected to the turning assembly through a rotating shaft 9, and the rotating shaft 9 is located in the middle of the turning assembly and the support assembly.

[0029] One end of the turning assembly is elastically damped by a spring 7 and connected to one end of the support assembly, a limiting block 3 is fixedly installed at the other end of the turning assembly, and a structural block 4 corresponding to contact with the limiting block 3 is fixedly installed at the other end of the support assembly.

[0030] The support assembly includes a base 5 for fixing on the deck of the hoisting platform, the structural block 4 is fixed on the right side end of the base 5, and the spring 7 is fixed on the left side end of the base 5;

[0031] A support block 11 fixed on the middle top of the base 5, and the support block 11 is provided with a through hole for the rotating shaft 9 to pass through; the top of the base 5 is arc-shaped and extends into a first rotating groove 12 provided by an arc groove plate 6 of the turning assembly; baffles 10 for limiting are fixed at both ends of the rotating shaft 9.

[0032] The turning assembly includes an arc groove plate 6 with an arc groove on the top surface, reinforcing plates 2 for strengthening are fixedly installed at intervals on the side of the arc groove plate 6, an anti-slip pad 1 is fixedly installed in the top arc groove of the arc groove plate 6, and the pipe pile is placed in the anti-slip pad 1; the limiting block 3 is fixed at the right side end of the bottom of the arc groove plate 6 to correspond to contact with the structural block 4, and the spring 7 corresponds to the left side end of the bottom of the arc groove plate 6;

[0033] A rotating block 8 fixed on the bottom surface of the arc groove plate 6, and the rotating block 8 is provided with a through hole for the rotating shaft 9 to pass through; the rotating blocks 8 are multiple and distributed at intervals and the bottom is arc-shaped, the support blocks 11 are multiple and distributed at intervals, a second rotating groove 13 is formed between two support blocks 11, so that the tops of multiple support blocks 11 extend into the first rotating groove 12 and can rotate, multiple rotating blocks 8 extend into the second rotating groove 13 and can rotate, and the rotating shaft 9 passes through the rotating blocks 8 and the support blocks 11, so that the rotating blocks 8 and the support blocks 11 can only rotate relative to each other and will not displace along the axial direction of the rotating shaft 9.

[0034] Working principle: During use, the flipping structure and the supporting structure are manufactured separately, and then the rotating block 8 and the supporting block 11 are connected through the rotating shaft 9. At this time, the supporting block 11 fits into the first rotating groove 12, and the rotating block 8 fits into the second rotating groove 13. Then, the end of the rotating shaft 9 is fixed with a baffle 10, and the spring 7 connecting the arc groove 6 and the base 5 is installed. The assembled structure as a whole is ensured to be in a horizontal state. Then, the whole device is installed on the edge of the hoisting ship through the base 5, with the side of the spring 7 facing outward. The straight line formed by connecting the centers of the three springs 7 is basically parallel to the edge of the hoisting ship. At this time, the pipe pile is placed on the anti-slip pad 1 of the arc groove 6, and the lifting ropes formed by steel wires are respectively hung at both ends of the pipe pile. The lifting rope on the inner side of the hoisting ship is slowly lifted, and at the same time, the lifting rope on the outer side of the hoisting ship is slowly lowered, making the pipe pile in an inclined state. At this time, the flipping structure of the device relies on the rotation of the rotating shaft 9 and serves as the fulcrum for the flipping of the pipe pile to complete the pile flipping operation.

[0035] During the use of this application, the pipe pile is placed in the anti-slip pad 1 of the flipping assembly. When the pipe pile is tilted and flipped on the supporting assembly through the flipping assembly, the spring 7 provides continuous variable damping support. The supporting assembly enables the flipping assembly to obtain rotational force through the rotating shaft 9, avoiding the situation of large swings in the air caused by the blowing of the sea breeze during the hoisting and flipping of the pipe pile, improving the operation safety and efficiency, and solving the problems of poor safety and low efficiency in the pipe pile flipping operation.
