Description

Technical Field

[0001] This invention relates to the field of offshore wind power engineering technology, and in particular to an offshore wind power steel pipe pile lifting and turning device. Background Technology

[0002] Offshore wind power has become a rapidly rising member of the clean energy sector by taking full advantage of the high wind speeds, stable wind power, and lack of land occupation. Although offshore wind power has many advantages over onshore wind power, building wind power facilities at sea requires overcoming many difficulties, the most prominent of which is constructing offshore wind power foundations on the seabed.

[0003] Chinese Patent Publication No. CN218114812U discloses a lifting and turning device for offshore wind power steel pipe piles, belonging to the field of offshore wind power engineering. This device includes: a shell; a telescopic assembly slidably disposed on the side of the shell; a drive assembly disposed within the shell and connected to the telescopic assembly for driving the telescopic assembly; and a lifting lug rotatably disposed at the rear end of the shell. This offshore wind power steel pipe pile lifting and turning device can automatically separate from the steel pipe pile without requiring operators to dive underwater for auxiliary operations, improving construction efficiency and reducing operational risks for construction personnel. Furthermore, the lifting lug remains vertical throughout the lifting process, with no relative movement between the hook and the lug, preventing disengagement accidents.

[0004] However, we found that the above design, which is based on a similar internal expansion method to fix the wind turbine steel pipe, is not stable enough and the form is relatively simple. Some wind turbine steel pipes are heavy, and this simple internal expansion method is not stable enough. Therefore, we designed an internal and external fixing method, and then designed an offshore wind turbine steel pipe pile lifting and turning device. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a lifting and turning device for offshore wind power steel pipe piles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lifting and turning device for offshore wind power steel pipe piles includes a conical shell, a sleeve fixed to the top of the conical shell, a plurality of side openings equidistantly opened on the outer wall of the sleeve, an ejection mechanism installed in the side openings, and a compression mechanism installed inside the conical shell to realize the ejection mechanism.

[0008] A fixing ring is fixed to the top of the casing, and an outer mounting sleeve is fixed to the fixing ring. The outer mounting sleeve is located on the outer wall of the casing. Several mounting slots are equally spaced on the outer mounting sleeve, and extrusion components are installed in the mounting slots. The extrusion mechanism is connected to a pulling component that realizes the extrusion component to form an extrusion.

[0009] As a further embodiment of the present invention, the ejection mechanism includes a mounting shell fixed to the inner wall of the side opening, a pressing block slidably disposed inside the mounting shell, and a protective pad fixed to the outer wall of the pressing block.

[0010] As a further embodiment of the present invention, the top and bottom of the mounting shell are provided with sliding grooves, and the top and bottom of the extrusion block are fixed with perforated fixing blocks near the extrusion mechanism. The inner wall of the sliding groove is fixed with a limiting rod passing through the perforated fixing block, and the outer wall of the perforated fixing block is fitted with a spring. The arrangement of the spring and the perforated fixing block can achieve the effect of resetting the extrusion block.

[0011] As a further embodiment of the present invention, the extrusion mechanism includes a hydraulic cylinder fixed to the inner wall of the conical shell, the output shaft of the hydraulic cylinder is fixed with a conical extrusion block, and the side of the mounting shell facing the conical extrusion block is configured as an inclined surface adapted to the conical extrusion block.

[0012] As a further embodiment of the present invention, the extrusion member includes a pressure plate rotatably disposed on the inner wall of the mounting groove, an extrusion plate disposed above the pressure plate and located in the mounting groove, and two symmetrical inclined plates fixed on the outer wall of the pressure plate away from the extrusion plate. The fixed plates can be adjusted by rotating the top rod, thereby adjusting the position of the extrusion plate inside the mounting groove. Through the above adjustment, the stroke of the pressure plate is achieved by the extrusion inclined plates to achieve the tilting extrusion of the pressure plate.

[0013] As a further embodiment of the present invention, the pulling member includes a top rod fixed to the top of the conical extrusion block. A fixing plate is provided at the top of the top rod. A connecting rod is fixed to the extrusion plate. The connecting rod is fixed to the bottom of the fixing plate. A through groove is provided on the fixing ring for the connecting rod to pass through. An external thread is provided on the top of the outer wall of the top rod. A threaded sleeve is threadedly connected to the top rod. The top of the threaded sleeve is rotatably connected to the bottom of the fixing plate. By rotating the top rod, the fixing plate can be adjusted, thereby adjusting the position of the extrusion plate inside the mounting groove. Through the above adjustment, the stroke of the extrusion plate to achieve the tilting and extrusion of the pressure plate can be realized.

[0014] As a further embodiment of the present invention, a mounting ring is fixed to the top of the fixing ring, and a lifting lug is fixed to the outer wall of the mounting ring for mounting a hook.

[0015] The beneficial effects of this invention are as follows:

[0016] This invention utilizes a conical shell, a sleeve, an ejector mechanism, a pressing mechanism, a pulling component, a pressing component, and a push rod. The pulling component is used to pull the pressing plate to slide, so the hydraulic cylinder operates, causing the conical pressing block to move. The conical pressing block pushes the pressing block to slide within the mounting shell, causing the protective pad on the outer wall of the pressing block to press against the inner wall of the wind turbine steel pipe. Simultaneously, the pulling component on the conical pressing block pulls the pressing plate to move, and the pressing plate presses against the inclined plate, causing the inclined plate to press against the outer wall of the wind turbine steel pipe. This achieves simultaneous pressing against both the inner and outer walls of the wind turbine steel pipe, resulting in a more stable pressing and fixing effect, effectively preventing detachment. After installation, simply retracting the hydraulic cylinder releases the pressing and fixing of the wind turbine steel pipe, facilitating the removal of the device.

[0017] This invention features a pull member comprising a top rod, an external thread, a fixed plate, and a pressure plate. The fixed plate is rotatably connected to a threaded sleeve rod, and the threaded sleeve rod is threadedly connected to the top rod. By rotating the top rod, the fixed plate can be adjusted, thereby adjusting the position of the extrusion plate inside the mounting groove. Through the above adjustment, the stroke of the extrusion plate is adjusted to achieve the tilting and extrusion of the pressure plate. Attached Figure Description

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Reference Figure 1-6 A lifting and turning device for offshore wind power steel pipe piles includes a conical shell 1, a sleeve 2 fixed to the top of the conical shell 1, a plurality of side openings 17 equidistantly opened on the outer wall of the sleeve 2, an ejection mechanism 3 installed in the side openings 17, and a squeezing mechanism for ejecting the ejection mechanism 3 installed inside the conical shell 1.

[0030] In this embodiment, the top and bottom of the mounting shell 301 are provided with sliding grooves 6, and the top and bottom of the extrusion block 302 are fixed with opening fixing blocks 8 near the extrusion mechanism. The inner wall of the sliding groove 6 is fixed with a limiting rod 7 that passes through the opening fixing block 8, and the outer wall of the opening fixing block 8 is fitted with a spring 9. The arrangement of the spring 9 and the opening fixing block 8 can achieve the effect of resetting the extrusion block 302.

[0031] In this embodiment, the extrusion mechanism includes a hydraulic cylinder 4 fixed to the inner wall of the conical shell 1. The output shaft of the hydraulic cylinder 4 is fixed with a conical extrusion block 5. The side of the mounting shell 301 facing the conical extrusion block 5 is set as an inclined surface adapted to the conical extrusion block 5.

[0032] In this embodiment, the extrusion member 16 includes a pressure plate 161 rotatably disposed on the inner wall of the mounting groove 15. An extrusion plate 162 located in the mounting groove 15 is disposed above the pressure plate 161. Two symmetrical inclined plates 163 are fixed on the outer wall of the pressure plate 161 away from the extrusion plate 162. The fixed plate 20 can be adjusted by rotating the top rod 18, thereby adjusting the position of the extrusion plate 162 inside the mounting groove 15. Through the above adjustment, the stroke of the extrusion inclined plates 163 to achieve the inclined extrusion of the pressure plate 161 is achieved.

[0033] In this embodiment, the pulling component includes a top rod 18 fixed to the top of the conical extrusion block 5. A fixing plate 20 is provided on the top of the top rod 18. A connecting rod 164 is fixed to the extrusion plate 162. The connecting rod 164 is fixed to the bottom of the fixing plate 20. A through groove 11 is provided on the fixing ring 10 for the connecting rod 164 to pass through. An external thread 19 is provided on the top of the outer wall of the top rod 18. A threaded sleeve 21 is threadedly connected to the top rod 18. The top of the threaded sleeve 21 is rotatably connected to the bottom of the fixing plate 20. By rotating the top rod 18, the fixing plate 20 can be adjusted, thereby adjusting the position of the extrusion plate 162 inside the mounting groove 15. Through the above adjustment, the stroke of the extrusion inclined plate 163 to achieve the tilting extrusion of the pressure plate 161 can be achieved.

[0034] In this embodiment, a mounting ring 13 is fixed to the top of the fixing ring 10, and a lifting lug 14 is fixed to the outer wall of the mounting ring 13 for mounting a hook.

[0035] Working principle: The system comprises a conical shell 1, a sleeve 2, an ejection mechanism 3, a pressing mechanism, a pulling component, a pressing component 16, and a top rod 18. The pressing mechanism includes a hydraulic cylinder 4 and a conical pressing block 5. The ejection mechanism 3 includes a mounting shell 301, a pressing block 302, and a protective pad 303. The pulling component includes a top rod 18, a connecting rod 164, and a fixing plate 20. The pressing component 16 includes a pressure plate 161, a pressing plate 162, and an inclined plate 163, and is positioned in the mounting groove 15 on the inner wall of the outer mounting sleeve 12. The pulling component is used to pull the pressing plate 162 to slide. Through this design, the conical shell 1 is inserted into the inner wall of the wind turbine steel pipe, the outer mounting sleeve 12 is fitted onto the outer wall of the wind turbine steel pipe, and the lifting hook is attached to the lifting lug 14. The operation of the hydraulic cylinder 4 causes the conical extrusion block 5 to move, which in turn pushes the extrusion block 302 to slide within the mounting shell 301. This causes the protective pad 303 on the outer wall of the extrusion block 302 to press against the inner wall of the wind turbine steel pipe. Simultaneously, the pulling element on the conical extrusion block 5 pulls the extrusion plate 162 to move. The extrusion plate 162 moves and presses against the inclined plate 163, causing the pressure plate 161, which is rotatably set in the mounting groove 15, to be pressed down. This causes the inclined plate 163 to press against the outer wall of the wind turbine steel pipe. In this way, the inner and outer walls of the wind turbine steel pipe are simultaneously pressed, resulting in a more stable pressing and fixing effect, effectively preventing detachment. After installation, the hydraulic cylinder 4 can be retracted to release the pressing and fixing of the wind turbine steel pipe, making it easy to remove the equipment.

[0036] Furthermore, the pull component includes a top rod 18, an external thread 19, a fixed plate 20, and a pressure plate 161. The fixed plate 20 is rotatably connected to the threaded sleeve 21, and the threaded sleeve 21 is threadedly connected to the top rod 18. By rotating the top rod 18, the fixed plate 20 can be adjusted, thereby adjusting the position of the extrusion plate 162 inside the mounting groove 15. Through the above adjustment, the stroke of the extrusion inclined plate 163 to achieve the tilting extrusion of the pressure plate 161 can be achieved.
