Description

Technical Field

[0001] This invention relates to an automatic hook-and-unhook lifting device and method for ultra-high jacket supports. Background Technology

[0002] In the field of offshore wind power, jacket foundations are widely used due to their suitability for various water depths, short construction periods, convenient recycling, and energy-saving and environmentally friendly characteristics. Traditional construction methods typically involve transporting the jacket to the wind farm using deck transport barges, followed by hoisting and installing it onto the existing seabed foundation (pile foundations or suction hopper) using large floating cranes. This method is mature and stable. Currently, as the development and construction of offshore wind power in China gradually moves towards deeper water and larger scale, the size and weight of jackets are increasing, with jacket weights generally exceeding 1500 tons. This places higher demands on the construction capabilities of large floating cranes. When hoisting ultra-high steel structure jackets, not only are specialized lifting tools made specifically for the jacket structure required, but bolts are also often used to connect the wire ropes to the lifting lugs at the top of the jacket. This makes the connection process cumbersome and inconvenient for workers. Furthermore, the wire ropes are relatively soft, requiring manual removal and connection at each anchor point, increasing the workload and affecting hoisting efficiency. Summary of the Invention

The thickness of the left guide block 22a is the same as the thickness of the right guide block 22b and is adapted to the protruding length of the guide shaft 162 on each plug 16. The space between every two adjacent second guide block groups 22 forms a second channel 220. The width of the second channel 220 is adapted to the diameter of the guide shaft 162. Each third guide block 23 is a quadrilateral formed by cutting off the upper left corner of a rectangle, resulting in a complete right side face, bottom face, a top inclined surface connected to the upper end of the right side face, and a left side face connected between the left end of the top inclined surface and the left end of the bottom face.

[0019] Please see again Figure 6 The present invention provides an automatic hooking and unhooking method for ultra-high jacket structures, based on the automatic hooking and unhooking lifting device for ultra-high jacket structures of the present invention. The automatic hooking and unhooking method includes a hooking process and a unhooking process.

[0020] The hooking process includes the following steps: S11. First, connect the main hook of the crane to the hooks of the three or four upper slings of the upper lifting device; S12. The upper lifting device is lowered by the main hook of the crane, and the plugs 16 of the three or four plug-in units 1B are inserted one by one into the guide bell mouth 2A of the three or four receiving units 2 and then into the corresponding sleeves 2B; the inverted cone of the plug 16 and the guide bell mouth 2A at the top of the sleeve 2B guide the plug 16 into the sleeve 2B. S13. When the plug 16 descends past the first guide block 21 inside the sleeve 2B, it is guided by the left top slope of each first guide block 21 and the right top slope of the adjacent first guide block 21, so that the six plug guide plates 161 on each plug 16 enter the six first channels 210 one by one. When the plug 16 continues to descend past the second guide block group 22 inside the sleeve 2B, it is guided by the upper right slope of the right guide block 22b of each second guide block group 22 and the upper left slope of the left guide block 22a of the adjacent second guide block group 22, and the thickness of the left guide block 22a and the thickness of the right guide block 22b are both greater than the first guide block 21. The guide block 21 is thin, so that the guide shafts 162 on the six plug guide plates 161 on each plug 16 slide into the six second channels 220 one by one. When the plug 16 continues to descend and passes the third guide block 23 in the sleeve 2B, the top inclined surface of the third guide block 23 located below each second channel 220 guides the plug 16 to rotate counterclockwise by an angle, so that the six guide shafts 162 on each plug 16 slide into the third channel 230 below the right guide block 22b of the six second guide block groups 22 one by one, until the six guide shafts 162 fall onto the limiting ring 2C in the sleeve 2B. S14. The upper lifting device is lifted by the main hook of the crane, so that the plugs 16 of the three or four plug-in units 1B rise. Each plug 16 is first guided by the bottom inclined surface of the right guide block 22b of the second guide block group 22 in the sleeve 2B and then rotated counterclockwise by an angle, so that the six guide shafts 162 on each plug 16 slide into the six hook channels 22A one by one. The plugs 16 continue to rise until the top surface of the six plug guide plates 161 on each plug 16 is in contact with the bottom surface of the six first guide blocks 21, thus completing the automatic hooking of the upper lifting device with the guide frame. The guide frame can then be lifted by the crane, so that the six first guide blocks 21 in the sleeve 2B of the three or four receiving units 2 bear the weight of the entire guide frame. The decoupling process includes the following steps: S21. The upper lifting device is lowered by the main hook of the crane, so that the plugs 16 of the three or four plug-in units 1B pass through the top inclined surface of the third guide block 23 below each hook channel 22A in the corresponding sleeve 2B, so that each plug 16 rotates counterclockwise by an angle, and the six guide shafts 162 on each plug 16 slide into the third channel 230 below the left guide block 22a of the six second guide block groups 22, until the six guide shafts 162 fall onto the limiting ring 2C in the sleeve 2B. S22. The upper lifting device is lifted by the main hook of the crane. Guided by the bottom slope of the left guide block 22a of the six second guide block groups 22, each plug 16 is rotated counterclockwise by an angle, so that the six guide shafts 162 on each plug 16 enter the six second channels 220 one by one. The upper lifting device is continued to be lifted, so that the six plug guide plates 161 on each plug 16 enter the six first channels 210 one by one, until the plugs 16 of three or four plug-in units 1B are disengaged from the sleeves 2B and guide bell mouths 2A of three or four receiving units 2, thus completing the automatic unhooking of the upper lifting device from the guide frame.

[0021] The automatic hooking and unhooking method for ultra-high guide frames of the present invention, in the case that the lower sling 13 is a flexible sling and the number of first guide blocks 21 inside the sleeve 2B is six, allows each plug 16 to rotate 60° counterclockwise throughout the entire process from hooking to unhooking. Of course, the number of first guide blocks 21 inside the sleeve 2B is not limited to six; if the inner diameter of the sleeve 2B is increased, the number of first guide blocks 21 can be increased to eight or twelve.

[0022] The above embodiments are for illustrative purposes only and are not intended to limit the invention. Those skilled in the art can make various changes or modifications without departing from the spirit and scope of the invention. Therefore, all equivalent technical solutions should also fall within the scope of the invention and should be defined by the claims.

The plug rises, and several guide shafts on the plug slide into several hook channels one by one until the top surfaces of several plug guide plates on the plug are in contact with the bottom surfaces of several first guide blocks. The decoupling process includes the following steps: S21. The plug descends. Several guide shafts on the plug slide into the third channel below the left guide block of several second guide block groups in a corresponding manner until each guide shaft falls onto the limiting ring inside the sleeve. S22. The plug rises, and several guide shafts on the plug enter several second channels in a corresponding manner, and several plug guide plates enter several first channels in a corresponding manner, until the plug is separated from the sleeve and the guide flare.

4. The automatic hooking and unhooking method for ultra-high guide frames according to claim 3, characterized in that, The specific process of step S13 is as follows: When the plug descends and passes the first guide block inside the sleeve, the left top slope of each first guide block and the right top slope of the adjacent first guide block guide the plug guide plates on each plug to enter the first channels one by one. When the plug continues to descend and passes the second guide block group inside the sleeve, the right upper slope of the right guide block of each second guide block group and the left upper slope of the left guide block of the adjacent second guide block group guide the guide shafts on the plug guide plates on each plug to slide into the second channels one by one. When the plug continues to descend and passes the third guide block inside the sleeve, the top slope of the third guide block located below each second channel guides the plug to rotate counterclockwise by an angle, so that the guide shafts on each plug slide into the third channels below the right guide blocks of the second guide block groups one by one, until the guide shafts fall onto the limiting rings inside the sleeve. The specific process of step S14 is as follows: the upper lifting device is lifted by the main hook of the crane, so that the plugs of three or four plug-in units rise. Each plug is first guided by the bottom inclined surface of the right guide block of the second guide block group and then rotated counterclockwise by an angle, so that several guide shafts on each plug slide into several hook channels one by one. The plug continues to rise until the top surface of several plug guide plates on each plug is in contact with the bottom surface of several first guide blocks, thus completing the automatic hooking of the upper lifting device and the guide frame. The specific process of step S21 is as follows: the upper lifting device is lowered by the main hook of the crane, so that the plugs of the three or four plug-in units pass through the top inclined surface of the third guide block below each hook channel in the corresponding sleeve, so that each plug rotates counterclockwise by an angle, and the several guide shafts on each plug slide into the third channel below the left guide block of several second guide block groups one by one, until each guide shaft falls onto the limiting ring in the sleeve. The specific process of step S22 is as follows: the upper lifting device is lifted by the main hook of the crane, and guided by the bottom inclined surface of the left guide block of several second guide block groups, each plug is rotated counterclockwise by an angle, so that several guide shafts on each plug enter several second channels one by one. The upper lifting device is continued to be lifted, so that several plug guide plates on each plug enter several first channels one by one, until the plugs of three or four plug-in units are disengaged from the sleeves and guide bell mouths of three or four receiving units one by one, thus completing the automatic disengagement of the upper lifting device from the guide frame.
