DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] like Figures 1 to 10 As shown, the present invention's lifting device opening structure for offshore wind turbine cylinders includes a hook 1 and a movable assembly 2. The movable assembly 2 can be used separately from the hook 1. During lifting, the movable assembly 2 can be removed to maximize the opening area 3, facilitating the lifting of the wind turbine cylinder. A cable or chain can be placed in the hanging area 4, and then the movable assembly 2 can be used to block the opening area 3.

[0020] The hook 1 is arranged in a U-shaped structure, with an opening area 3 provided on the hook 1, a hanging area 4 formed in the middle of the hook 1, and a fixing portion 5 symmetrically arranged and extending into the hanging area 4 at the opening area 3. A fixing area 6 is formed between the fixing portions 5, and the pulling member 7 is in the fixing area 6.

[0021] The hook 1 is composed of a first horizontal section 8, an arcuate section 9, an inclined section 10, and a second horizontal section 11. The first and second horizontal sections 8 and 11 form an opening area 3, and the first and second horizontal sections 11 and the arcuate section 9 form the suspension area 4. The distance between the first and second horizontal sections 8 and 11 is less than the diameter of the arcuate section 9, so that the height of the opening area 3 is less than the height of the suspension area 4. When a cable or chain passes through the opening area 3 and enters the suspension area 4, it can slide into the suspension area 4 via the inclined section 10. Furthermore, because the suspension area 4 is lower and the opening area 3 is higher, the cable or chain within the suspension area 4 can be stably placed within the suspension area 4, preventing it from easily escaping from the restraints of the opening area 3.

[0022] The fixed portion 5 is mounted on the first horizontal section 8. An extension 12 is provided at the junction of the first horizontal section 8 and the curved section 9. A first lifting area 13 is formed between the extension 12 and the curved section 9, while a second lifting area 14 is formed between the extension 12 and the fixed portion 5. During lifting, a cable or chain connected to the crane can be placed within the first lifting area 13 or the second lifting area 14 to maintain the stability of the entire sling 15 and prevent it from shifting.

[0023] The first horizontal section 8 is provided with a relief opening 16 , in which a relief slope 17 is provided. The relief opening 16 can be used for the installation of the movable component 2 without blocking the movable component 2 .

[0024] A first hinge hole 18 and a through slot 19 are provided on the second horizontal section 11 . The first hinge rod 20 is disposed in the first hinge hole 18 , and the hinge end 21 is disposed in the through slot 19 .

[0025] The fixing portion 5 is provided with a first retaining hole 22 and a second retaining hole 23. The retaining rod 24 is disposed in the first retaining hole 22, and the blocking rod 25 is disposed in the second retaining hole 23. The retaining rod 24 is located close to the extension body 12, while the retaining rod 24 is located away from the extension body 12.

[0026] The movable assembly 2 is arranged at the opening area 3 and includes a blocking member 26, a retaining member 27, and a pulling member 7. The blocking member 26 is used to block the opening area 3, while the retaining member 27 is used to limit the position of the blocking member 26. The pulling member 7 is used to release the restriction between the retaining member 27 and the hook 1 so that the retaining member 27 can be removed.

[0027] A blocking member 26 is provided at the opening area 3 and is used to close the hanging area 4. The blocking member 26 comprises a hinged end 21, a main body 28, and a mounting end 29. The hinged end 21 is hinged to the hook 1 via a first hinge rod 20. A notch 30 is provided in the hinged end 21. The width of the notch 30 matches the diameter of the first hinge rod 20. When the blocking member 26 is installed in the through-slot 19, the opening direction of the notch 30 remains aligned with the opening direction of the through-slot 19.

[0028] When installing the blocking member 26 , it is only necessary to first keep the blocking member 26 and the second horizontal section 11 in a horizontal and parallel state, then fit the notch 30 with the first hinge rod 20 , and finally rotate the blocking member 26 90°.

[0029] The retaining member 27 is arranged on the mounting end 29, and the retaining member 27 is provided with a retaining end 31, and the retaining end 31 is provided with a retaining opening 32, and the retaining end 31 is provided with a guide slope 33. The guide slope 33 is used to cooperate with the retaining rod 24, so that the retaining end 31 can be blocked by the retaining rod 24 and guide the retaining end 31 to rotate upward, and then the retaining end 31 passes over the retaining rod 24, so that the retaining opening 32 cooperates with the retaining rod 24 to limit the position.

[0030] The fixing portion 5 is provided with a retaining rod 24 and a blocking rod 25. The retaining rod 24 cooperates with the retaining opening 32 to limit the position. A spring 34 is provided between the retaining member 27 and the mounting end 29. The retaining member 27 is provided with a pressure portion 35. A bearing portion 37 is provided on the second mounting portion 36. A positioning post 38 is provided on the pressure portion 35 and the bearing portion 37. The spring 34 is sleeved on the positioning post 38.

[0031] The spring 34 is used to push the retaining member 27 to rotate so that the retaining rod 24 is placed in the retaining opening 32. A second hinged rod 39 is provided on the mounting end 29. The retaining member 27 is hinged to the mounting end 29 through the second hinged rod 39. A mounting area 40 is formed in the middle of the retaining member 27, and the mounting end 29 is arranged in the mounting area 40.

[0032] The mounting end 29 is provided with a first mounting portion 41 and a second mounting portion 36. A movable opening 42 is formed between the first mounting portion 41 and the second mounting portion 36. A tension spring 43 is disposed within the movable opening 42. A positioning rod 44 is provided on the mounting end 29. A positioning hole 45 is provided on the mounting end 29, which cooperates with the positioning rod 44. A connecting groove 46 is provided in the center of the positioning hole 45. The connecting groove 46 communicates with the movable opening 42, facilitating the installation of the tension spring 43 and the positioning rod 44. A pulling member 7 is provided with a pulling rod 47, and a guide groove 48 is provided on the retaining member 27 to accommodate the pulling rod 47. One end of the tension spring 43 is connected to the positioning rod 44, and the other end is connected to the pulling rod 47. The pulling member 7 is provided with a second fixing hole 49 that cooperates with the pulling rod 47.

[0033] The pull member 7 is used to change the position of the retaining member 27. The middle of the pull member 7 is hollowed out to form an active area 50, and the retaining member 27 is disposed within the active area 50. When the pull member 7 is pulled, the retaining member 27 is pushed by the pull member 7, driving the blocking member 26 toward the blocking rod 25, so that the retaining opening 32 on the retaining member 27 cooperates with the retaining rod 24 to limit the position.

[0034] The guide groove 48 is provided with a first flat surface 51, a guide slope 52, and a second flat surface 53. The first flat surface 51 and the second flat surface 53 are connected by the guide slope 52. The height of the second flat surface 53 is greater than that of the first flat surface 51. When the pull rod 47 on the first flat surface 51 reaches the second flat surface 53, since the position of the pull rod 47 cannot be changed, the retaining member 27 is subjected to force only when the pull rod 47 moves along the guide slope 52, thereby pressing the retaining member 27 downward and rotating the retaining member 27 about the second hinge rod 39, thereby disengaging the retaining rod 24 from the retaining opening 32.

[0035] The retaining member 27 is provided with an arcuate hole 55, within which a guide rod 56 is disposed. The guide rod 56 is disposed on the mounting end 29, and the pulling member 7 is provided with a first strip-shaped hole 57 that cooperates with the guide rod 56. Since the pulling rod 47 is stationary, the pulling member 7 drives the pulling rod 47 to cooperate with the guide groove 48, which allows the guide rod 56 to move relative to the first strip-shaped hole 57. In fact, it is the first strip-shaped hole 57 that moves, and since the guide rod 56 is still within the arcuate hole 55, the arcuate hole 55 rotates along the guide rod 56 around the second hinge rod 39.

[0036] A second hinge hole 58 is provided on the holding member 27 , and the second hinge rod 39 is located in the second hinge hole 58 .

[0037] The pulling member 7 is provided with a second strip-shaped hole 59 and a third strip-shaped hole 60. The second hinge rod 39 is disposed in the second strip-shaped hole 59. The mounting end 29 is provided with a limiting rod 61, which is disposed in the third strip-shaped hole 60. The limiting rod 61 is used to limit the rotation of the retaining member 27, thereby limiting the rotation angle of the retaining member 27 about the second hinge rod 39.

[0038] A movable rod 62 is further provided on the mounting end 29, a square hole 63 is provided on the retaining member 27, and a first fixing hole 64 is provided on the pulling member 7 to cooperate with the movable rod 62. The movable rod 62 is disposed in the square hole 63. The movable rod 62 cooperates with the square hole 63, thereby further improving the stability of the retaining member 27 during rotation and improving the connection between the retaining member 27, the pulling member 7, and the blocking member 26.

[0039] like Figure 10As shown, to better illustrate the stress state analysis of the sling 15, the sling 15 is shown in a separated state, but remains assembled when stressed. When the pull member 7 is pulled in the direction F1, the pull rod 47 engages the guide slot 48, causing the guide slot 48 to maintain the position of the second plane 53 at the height of the first plane 51 under the pressure of the pull rod 47. As a result, the end of the retaining member 27 closest to the spring 34 is forced downward, keeping the spring 34 compressed and causing the retaining member 27 to rotate about the second hinge rod 39. This causes the arc-shaped hole 55 and the guide rod 56 to engage, causing the guide rod 56 to move relative to the arc-shaped hole 55. The retaining end 31 of the retaining member 27 is rotated in the direction of F2, so that the retaining opening 32 and the retaining rod 24 are separated. At this time, the retaining member 27 is no longer limited by the retaining rod 24, that is, the blocking member 26 can be rotated around the first hinge rod 20. When the blocking member 26 is rotated 90° clockwise, the notch 30 is set downward, and the blocking member 26 can be removed.

[0040] Since the pulling member 7 needs to be pulled outward by force, in actual use, even if the pulling member 7 is hit and approaches the retaining member 27, the retaining member 27 will not be separated from the retaining rod 24. By setting the pulling separation, the stability and safety of the entire sling 15 can be effectively improved, avoiding the sling 15 being opened due to accidents, thereby preventing accidents.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
