[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0027] Please refer to the following: Figures 1-5 ,in, Figure 1 A three-dimensional structural schematic diagram of the sand pile boat pipe pile extension device provided by this utility model; Figure 2 A three-dimensional structural schematic diagram of the sand pile boat pipe pile extension device provided by this utility model; Figure 3 A schematic diagram of the hydraulic mechanical clamping arm and the extended tube structure provided by this utility model; Figure 4 Provided by this utility model Figure 2 Enlarged structural diagram at point A in the middle; Figure 5 This is a schematic diagram of the main structure of the sand pile boat pipe pile extension device provided by this utility model.
[0028] In the specific implementation process, such as Figures 1-5 As shown, the pipe pile extension device for sand pile vessels is used to extend pipe piles during sand pile vessel operations. Its overall structure is installed on the deck surface 1 of the vessel. Through the coordinated operation of various components, the stable lifting, vibration sinking, and reliable connection with the extension pipe 10 of the pipe pile 6 are achieved, thereby completing the pipe pile extension operation.
[0029] A support frame 2 is fixedly installed on one side of the ship's deck surface 1 by welding.
[0030] On the other side of the ship's deck surface 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, it is necessary to ensure that the axis of the pulley 4 is horizontal and can rotate freely, so as to reduce the friction of the wire rope when the hoist 3 lifts the wire rope around the pulley 4 and ensure the normal operation of the wire rope.
[0032] After the hoisting wire rope of the winch 3 passes over the pulley 4, one end of it is fixedly connected to the top of the vibratory hammer 5.
[0033] The top of the pile pipe 6 is fixedly connected to the bottom of the vibratory hammer 5 via flanges and connecting bolts. During the connection process, it is necessary to ensure the parallelism and perpendicularity between the flanges, and tighten the connecting bolts 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 surface 1 near the support frame 2, a widened platform 7 is fixedly installed by welding to increase working space and stability. A fixing frame 8 is then fixedly installed on the widened platform 7 by welding, ensuring that the fixing frame 8 is perpendicular to the widened platform 7, providing stable support for the subsequent installation of the hydraulic mechanical clamping arm 9.
[0035] The hydraulic mechanical clamping arm 9 includes:
[0036] First support pipe 11 and first hydraulic cylinder 12: The first support pipe 11 is fixedly installed on the fixed frame 8 by welding, ensuring that the first support pipe 11 is perpendicular to the fixed frame 8. The first hydraulic cylinder 12 is installed inside the first support pipe 11, so that the first hydraulic cylinder 12 can extend and retract stably.
[0037] Mounting plate 21 connection: Mounting plate 21 is fixedly connected to the piston rod of the first oil cylinder 12 by bolt connection or other means to ensure that 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 pipe 14 and the second hydraulic cylinder 15: Two symmetrical second support pipes 14 are fixedly installed on the mounting plate 21. The two second hydraulic cylinders 15 are respectively fixedly installed in the two second support pipes 14, ensuring that the axis of the second hydraulic cylinder 15 coincides with the axis of the second support pipe 14.
[0039] The sliding head 16 is connected to the chuck 17: The sliding head 16 is fixedly connected to the piston rods of the two second hydraulic cylinders 15 by welding or bolting. Two symmetrically arranged chucks 17 are hinged to the support plate 13 via hinge shafts, ensuring that the chucks 17 can rotate freely around the hinge shafts. Slide grooves 18 are provided on both chucks 17, allowing the sliding head 16 to slide within the slide grooves 18, thereby realizing the opening and closing action of the chucks 17.
[0040] An extension tube 10 is provided between the two hydraulic mechanical clamping arms 9. 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 installed on the top of the clamp 17 by welding, making it easy for workers to stand.
[0042] On the extension tube 10, a fall prevention block 20 is fixedly installed above the clamp 17 by welding. The fall prevention block 20 is distributed in a circumferential array to ensure that when the extension tube 10 is subjected to axial force, the fall prevention block 20 can effectively prevent the extension tube 10 from falling out of the clamp 17, thereby improving the safety of operation.
[0043] At both ends of the extension pipe 10, flanges are provided that can be connected to the pile pipe 6 and the vibratory hammer 5 by connecting bolts. The specifications and dimensions of the flanges must match the flanges on the pile pipe 6 and the vibratory hammer 5 in order to achieve a reliable connection between the extension pipe 10 and the pile pipe 6 and the vibratory hammer 5.
[0044] The working principle of the sand pile boat pipe pile extension device provided by this utility model is as follows: The vibratory hammer 5 and the pile pipe 6 are suspended under the pulley 4. The vibratory hammer 5 and the pile pipe 6 are connected by connecting bolts and flanges. The extension pipe 10 is clamped by the hydraulic mechanical clamping arm 9 on the widening platform 7. The winch 3 is started, and the vibratory hammer 5 and the pile pipe 6 are slowly lowered. At the same time, the vibratory hammer 5 is started to vibrate, which helps the pipe pile 6 sink. The vibratory hammer 5 sinks to a height lower than the lowest height of the extension pipe 10. The flange bolts are removed, and the section of the vibratory hammer 5 is raised to a height higher than the highest height of the extension pipe 10. The first cylinder 12 of the hydraulic mechanical clamping arm 9 on the widening platform pushes the extension pipe 10 between the vibratory hammer 5 and the bottom pile pipe 6. The vibratory hammer 5 and the pile pipe 6 are fixedly connected at both ends of the extension pipe 10 by connecting bolts. The winch 3 is started, and the vibratory hammer 5 is slowly lowered. At the same time, the vibratory hammer 5 is started to vibrate, which helps the extension pipe 10 sink. The vibratory hammer 5 is driven down to the initial position, realizing the extension of the pile pipe 6.
[0045] The sand pile boat pipe pile extension device of this utility model can efficiently and stably complete the extension operation of pipe piles, improve construction efficiency and quality, and at the same time ensure the safety of the operation.
[0046] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
