Description

Technical Field

[0001] This utility model relates to an automatic pile-turning device, belonging to the technical field of offshore hoisting equipment. Background Technology

[0002] In offshore wind power steel pipe pile foundation construction, a double-hook system is often used to flip the steel pipe pile. One main hook is connected to the lifting lug of the steel pipe pile, while the other main hook is connected to the pile bottom via a tail chute. After the steel pipe pile is flipped, the entire weight is borne by a single main hook. In existing pile flipping methods, when the steel pipe pile is flipped and in a vertical position, the hook connected to the tail chute needs to be lowered to release the tension on the bottom of the steel pipe pile, allowing the tail chute to detach from the bottom. At this point, the tail chute and its hook are tilted. Under gravity, the tail chute swings significantly the moment it detaches from the bottom of the steel pipe pile, requiring manual traction to stop the swing. This is time-consuming, labor-intensive, and affects work efficiency. Furthermore, it may collide with the steel pipe pile or other construction equipment and personnel, affecting construction safety. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide an automatic pile turning device that can automatically detach the tail of the pile from the steel pipe pile during pile turning operations, eliminate various problems that may be caused by the swinging of the tail during the detachment process, and improve the efficiency and safety of pile turning operations.

[0004] The purpose of this utility model is achieved as follows:

[0005] An automatic pile turning device includes a triangular lifting beam, a steel pipe pile lifting beam, and a tail end, wherein the triangular lifting beam is equipped with a composite lifting tool and an automatic unhooking system;

[0006] The composite lifting device includes a first lifting point, a second lifting point, and a third lifting point arranged in a triangular structure; the lower parts of the first and second lifting points are connected to the steel pipe pile lifting beam, and the lower part of the steel pipe pile lifting beam is connected to the lifting lug of the steel pipe pile; the third lifting point is connected to the tailstock.

[0007] The automatic unhooking system includes a pin and a hydraulic cylinder set at the third lifting point, and a control system set on the triangular lifting beam. The control system controls the hydraulic cylinder to extend and retract, thereby controlling the pin to extend and retract within the hook hole at the third lifting point. When the pin disengages from the hook hole at the third lifting point, the rope loop hooking the tail automatically disengages from the third lifting point, thus achieving automatic unhooking of the tail.

[0008] Furthermore, the top of the triangular lifting beam is hoisted by one or two sets of main hooks equipped with cross hooks.

[0009] Furthermore, the steel pipe pile lifting beam is a straight beam; the lower part of the straight beam is provided with several sets of lifting points with different spans to accommodate steel pipe piles of different diameters.

[0010] Furthermore, the lower part of the beam is provided with three sets of lifting points, and the three lifting points on both sides are distributed symmetrically in a triangular shape.

[0011] Furthermore, the control system includes a hydraulic station, a control module, valves, and pipelines; the control module includes a remote control receiver module, which, upon receiving a wireless unhooking signal, controls the hydraulic cylinder to drive the pin to exit the hook hole of the third lifting point, thereby achieving automatic unhooking of the tail section.

[0012] Furthermore, a sleeve seat coaxially arranged with the hanging hole is fixedly installed on the side of the third lifting point, the pin is slidably arranged in the sleeve seat, the oil cylinder is fixedly installed on the side of the sleeve seat, and the piston rod of the oil cylinder is connected to the pin through the side wall of the sleeve seat.

[0013] Furthermore, the rope loop comprises several wire rope loops connected end to end by bow-shaped shackles.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention employs a composite lifting point on a triangular lifting beam. A straight beam and a tail section are respectively attached below the composite lifting point. The straight beam is connected to the lifting lugs of the steel pipe pile, and the tail section connects to the tail of the steel pipe pile, thus enabling the lifting of the steel pipe pile. An automatic unhooking system is installed on the triangular beam. The pin on the composite lifting point is automatically disengaged from the attachment hole under the control of the automatic unhooking system, causing the rope loop pulling the tail section to disengage from the composite lifting point. This achieves automatic unhooking of the tail section, eliminating the problem of large swings during the unhooking process and eliminating the need for manual traction to stop the swing of the tail section, thereby improving the efficiency and safety of pile turning operations.

[0025] See Figures 1-6 This utility model relates to an automatic pile turning device, which includes a triangular lifting beam 1, a steel pipe pile lifting beam 2, and a tail sliding device 3. The triangular lifting beam 1 is equipped with a composite lifting device 4 and an automatic unhooking system. The top of the triangular lifting beam 1 is lifted by one or two sets of main hooks 15 equipped with cross hooks 16. In this embodiment, two sets of main hooks 15 with a capacity of 2400 tons and 1800 tons are used, and the triangular lifting beam 1 is hooked to the two cross hooks 16 by a ring sling 7.

[0026] The composite lifting device 4 includes a first lifting point 41, a second lifting point 42, and a third lifting point 43 arranged in a triangular structure. The third lifting point 43 is connected to the tail 7 via a rope loop 8, and the rope loop 8 includes several wire rope loops connected end to end by bow-shaped shackles 6. The lower parts of the first lifting point 41 and the second lifting point 42 are connected to the steel pipe pile lifting beam 2 via annular slings 7. The steel pipe pile lifting beam 2 is a straight beam, and the lower part of the straight beam is connected to the lifting lugs of the steel pipe pile 5. The lower part of the straight beam is provided with several sets of lifting points 21 with different spans. Different lifting points 21 can be selected to adapt to steel pipe piles 5 of different diameters. In this embodiment, the lower part of the straight beam is provided with three sets of lifting points 21, and the three lifting points 21 on both sides are symmetrically distributed in a triangular shape.

[0027] The automatic unhooking system includes a pin 11 and a hydraulic cylinder 12 mounted on the third lifting point 43, and a control system 13 mounted on the triangular lifting beam 1. Specifically, a sleeve seat 14 coaxially mounted with the hanging hole is fixedly installed on the side of the hanging hole of the third lifting point 43. The pin 11 is slidably mounted in the sleeve seat 14. The hydraulic cylinder 12 is fixedly mounted on the side of the sleeve seat 14. The piston rod of the hydraulic cylinder 12 is connected to the pin 11 through the side wall of the sleeve seat 14.

[0028] The control system 13 controls the piston rod of the hydraulic cylinder 12 to extend and retract, thereby driving the pin 11 to extend and retract within the hook hole of the third lifting point 43. When the pin 11 disengages from the hook hole of the third lifting point 43 and retracts into the sleeve seat 14, the rope loop 8 hooking the tail 7 automatically disengages from the third lifting point 43, realizing the automatic unhooking of the tail 3. Specifically, the control system 13 includes a hydraulic station, a control module, valves, and pipelines. The control module includes a remote control receiving module. After receiving the wireless unhooking signal, the control module controls the hydraulic cylinder 12 to drive the pin 11 out of the hook hole of the third lifting point 43, realizing the automatic unhooking of the tail 3.

[0029] During the pile flipping operation, the steel pipe pile 5 is lifted from the transport barge by connecting the lifting lugs and the bottom of the steel pipe pile 5 via a straight beam and a tail sway 3. The steel pipe pile 5 is then gradually lowered to the seabed. When the bottom of the steel pipe pile 5 touches the seabed, the seabed provides support, and the rope loop 8 connecting the third lifting point 43 and the tail sway 3 loses its lifting tension and slackens. At this point, a remote control signal is sent, and the control system 13 controls the pin 11 to disengage from the hook hole of the third lifting point 43, causing the tail sway 3 to automatically disengage. The straight beam continues to lift the steel pipe pile 5 upwards, and the steel pipe pile 5, now freed from the traction of the tail sway 3, gradually flips from an inclined state to a vertical state with the help of the seabed, completing the pile flipping operation. Because the tail sway 3 automatically disengages, there is no problem of large-scale swaying, eliminating the need for manual traction to stop the swaying, thus improving the efficiency and safety of the pile flipping operation.

[0030] Additionally, it should be noted that the above-described specific implementation is merely an optimized solution of this patent, and any modifications or improvements made by those skilled in the art based on the above concept are within the scope of protection of this patent.
