[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] Please refer to Figure 1-Figure 5 ,in, Figure 1 A schematic diagram of the three-dimensional structure of the pipe pile extension device of the sand pile ship provided by the present invention; Figure 2 A schematic diagram of the three-dimensional structure of the pipe pile extension device of the sand pile ship provided by the present invention; Figure 3 A schematic diagram of the hydraulic mechanical clamping arm and extension tube structure provided by the present invention; Figure 4 The present invention provides Figure 2 A in the middle is an enlarged structural diagram; Figure 5 This is a schematic diagram of the main structure of the sand pile ship pipe pile extension device provided by the present invention.

[0028] In the specific implementation process, Figure 1-Figure 5 The pile extension device shown in the figure is used to extend piles during operations on a sand pile barge. The overall structure is mounted on the ship's deck 1. Through the coordinated cooperation of various components, the pile pipe 6 is stably lifted, vibrated and lowered, and securely connected to the extension tube 10, completing the pile extension operation.

[0029] On one side of the ship deck surface 1, a support frame 2 is fixedly installed by welding.

[0030] On the other side of the ship deck 1 away from the support frame 2, the winch 3 is fixedly installed with bolts to ensure the stability of the winch 3 during operation.

[0031] The pulley 4 is fixedly installed on the top of the support frame 2. During installation, ensure that the axis of the pulley 4 is horizontal and can rotate freely to reduce the friction of the winch 3 lifting wire rope when it passes around the pulley 4, ensuring the normal operation of the wire rope.

[0032] After the lifting wire rope of the winch 3 passes around the pulley 4, one end thereof is fixedly connected to the top of the vibrating hammer 5.

[0033] The top of the pile pipe 6 is fixedly connected to the bottom of the vibratory hammer 5 through a flange and connecting bolts. During the connection process, the parallelism and verticality between the flanges must be ensured, and the connecting bolts must be tightened with appropriate torque to ensure that the pile pipe 6 and the vibratory hammer 5 are tightly connected and will not loosen during operation.

[0034] On the side of the ship's deck 1 near the support frame 2, a widening platform 7 is welded and fixed to increase working space and stability. A fixing frame 8 is welded to the widening platform 7, ensuring that the fixing frame 8 is perpendicular to the widening platform 7, providing stable support for the subsequent installation of the hydraulic mechanical clamping arm 9.

[0035] The hydraulic mechanical clasping arm 9 comprises:

[0036] First support tube 11 and first oil cylinder 12: The first support tube 11 is fixed on the fixing frame 8 by welding, ensuring that the first support tube 11 is perpendicular to the fixing frame 8. The first oil cylinder 12 is installed in the first support tube 11 so that the first oil cylinder 12 can be stably extended and retracted.

[0037] Mounting plate 21 connection: The mounting plate 21 is fixedly connected to the piston rod of the first oil cylinder 12 by bolt connection or the like, ensuring that the mounting plate 21 is perpendicular to the piston rod of the first oil cylinder 12 and can accurately transmit the thrust of the first oil cylinder 12.

[0038] Installation of the second support tube 14 and the second oil cylinder 15: Two symmetrical second support tubes 14 are fixed on the mounting plate 21. The two second oil cylinders 15 are fixedly installed in the two second support tubes 14 respectively, ensuring that the axis of the second oil cylinder 15 coincides with the axis of the second support tube 14.

[0039] The sliding head 16 is connected to the clamping head 17: The piston rods of the two second oil cylinders 15 are fixedly connected to the sliding head 16 by welding or bolting. Two symmetrically arranged clamping heads 17 are hinged on the support plate 13 via an articulated axis, ensuring free rotation about the axis. Slide slots 18 are defined in both clamping heads 17, allowing the sliding head 16 to slide within them, thereby enabling the clamping heads 17 to open and close.

[0040] An extension tube 10 is arranged between the two hydraulic mechanical clamping arms 9 , and the outer diameter of the extension tube 10 is adapted to the inner diameter of the clamp 17 so that the clamp 17 can firmly clamp the extension tube 10 .

[0041] A mounting platform 19 is fixedly provided on the top of the clamping head 17 by welding, so that workers can stand conveniently.

[0042] On the extension tube 10, an anti-fall stop block 20 is fixedly set by welding and clamped above the clamp 17. The anti-fall stop block 20 is distributed in a circular array to ensure that when the extension tube 10 is subjected to axial force, the anti-fall stop block 20 can effectively prevent the extension tube 10 from falling off from the clamp 17, thereby improving the safety of the operation.

[0043] Flanges that can be connected to the pile pipe 6 and the vibratory hammer 5 through connecting bolts are provided at both ends of the extension tube 10. The specifications and dimensions of the flanges must match those on the pile pipe 6 and the vibratory hammer 5 so as to achieve reliable connection between the extension tube 10, the pile pipe 6 and the vibratory hammer 5.

[0044] When the pile is lowered to the bottom of the extension pipe 10, the vibrating hammer 5 and the pile pipe 6 are pushed up and the vibrating hammer 5 is driven up and down to the bottom of the extension pipe 10, thereby extending the pile pipe 6.

[0045] The sand pile ship pipe pile extension device of the present invention can efficiently and stably complete the pipe pile extension operation, improve construction efficiency and quality, and ensure the safety of the operation.

[0046] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
