Description

Technical Field

[0001] This application relates to the technical field of offshore hoisting equipment, and particularly relates to an ear for an offshore booster station with balanced force. Background Art

[0002] In recent years, with the development of the offshore wind power industry, the location of wind turbines has gradually moved from shallow sea areas to deep sea areas. The design of jacket foundations for the lower part of offshore wind power has gradually matured, but the forms of lifting lugs designed by each design unit still cannot be unified. Some use hole-type lifting lugs, and some use barrel-type lifting lugs.

[0003] However, during the use of existing lifting lugs, the lifted object may have uneven left and right weights, resulting in an inclined state of the lifted object after lifting. If it is not adjusted in time, it will seriously affect the subsequent installation of the lifted object by the staff and reduce work efficiency.

Specific implementation mode

[0034] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0035] Embodiment 1:

[0036] The present application discloses a lifting lug for an offshore booster station with balanced force. Please refer to Figures 1-3 which includes a lifting object and two welding pieces 1 welded to the lifting object. Above the two welding pieces 1, there is a lifting cylinder 2. The upper end of the lifting cylinder 2 is fixedly connected with a lifting lug 21. The same lifting rope 3 is sleeved between the two welding pieces 1, and the lifting rope 3 passes through the lifting cylinder 2 and is wound around the lifting lug 21. Two tooth plates 4 fixedly connected to the lifting rope 3 are slidably connected inside the lifting cylinder 2. A gear 41 is rotatably connected inside the lifting cylinder 2, and the gear 41 meshes with the tooth plate 4. The rear side wall of the lifting cylinder 2 is fixedly connected with a motor 42, and the output end of the motor 42 is fixedly connected with the gear 41. The lower end of the lifting cylinder 2 is fixedly connected with a connecting rod 5, and the lower end of the connecting rod 5 is fixedly connected with a switch cylinder 51.

[0037] Please refer to Figures 4-5, there are two moving blocks 52 slidably connected inside the switch cylinder 51. A spring plate 53 is fixedly connected to the center inside the switch cylinder 51. A tension spring 54 is fixedly connected between the moving block 52 and the spring plate 53. A force-receiving block 55 is fixedly connected to the lower side wall of the moving block 52. A connecting rope 56 is fixedly connected between the force-receiving block 55 and the welding part 1. Motor switch buttons 57 are installed on both the left and right side walls of the switch cylinder 51. Both of the two motor switch buttons 57 are electrically connected to the motor 42, and the two motor switch buttons 57 respectively control the forward and reverse rotations of the motor 42.

[0038] Please refer to Figures 5-8 , during use, first, install the welding part 1 onto the lifted object. Subsequently, the lifting equipment lifts the lifted object through the hook. When the weights of the lifted objects are inconsistent, it will be in an unbalanced state, causing the lifted object to tilt. As Figures 5-6 shown, the heavier side of the lifted object pulls the force-receiving block 55 to move through the connecting rope 56, thereby driving the moving block 52 to press the motor switch button 57, turning on the switch of the motor 42. The motor 42 drives the gear 41 to rotate clockwise. As Figures 7-8 shown, the toothed plate 4 drives the lifting rope 3 to move, and the lifting rope 3 pulls the lifted object to gradually balance.

[0039] When the lifted object is balanced, the connecting rope 56 can no longer pull the force-receiving block 55, causing the moving block 52, under the restoring pulling force of the tension spring 54, to no longer press the motor switch button 57, thereby achieving the purpose of balancing the lifted object.

[0040] Please refer to Figures 9-10 , limit cylinders 6 are fixedly connected to the upper ends of both toothed plates 4. Press plates 7 are installed at the upper ends of the two limit cylinders 6. A plurality of uniformly distributed pins 61 are slidably connected inside the limit cylinder 6. An electromagnet 63 is installed inside the pin 61 on one side of the pin 61. A magnetic sheet 62 is fixedly connected to one end of the plurality of pins 61 close to the electromagnet 63. A moving sheet 71 is slidably connected inside the press plate 7. A leather rope 72 is fixedly connected between the moving sheet 71 and the lifting lug 21, and the leather rope 72 penetrates through the press plate 7. An electromagnetic switch button 73 is installed on the upper inner wall of the press plate 7, and the electromagnetic switch button 73 is electrically connected to the electromagnet 63. The leather rope 72 is made of an elastic material.

[0041] Please refer to Figure 10 , the movement of the toothed plate 4 will synchronously drive the limit cylinder 6 and the press plate 7 to move. When the press plate 7 moves downward, the lifting lug 21 pulls the moving sheet 71 to press the electromagnetic switch button 73 through the leather rope 72, turning on the electromagnet 63 inside the lower limit cylinder 6 below it. The repulsive force generated by the electromagnet 63 pushes a plurality of magnetic sheets 62, driving the pins 61 to insert into the lower side of the other limit cylinder 6. As Figure 10As shown, it can further achieve the function of limiting the position, avoid the lifted object from returning to the unbalanced state again, and cause potential safety hazards. Finally, the motor 42 starts self-locking. On the one hand, it can avoid damaging the self-locking mechanism of the motor 42. On the other hand, it can play a double insurance role and improve the use safety.

[0042] After the hoisting is completed, the staff can change the polarity of the electromagnet 63 to attract the bolt 61 to retract, so as to achieve the purpose of resetting and facilitate the next use.

[0043] A plurality of balls are connected to the inner side wall of the lifting lug 21 in a rolling manner, and the plurality of balls are in contact with the lifting rope 3, which can effectively reduce the friction between the lifting rope 3 and the lifting lug 21.

[0044] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
