Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1-3, the rotatable offshore hoisting maintenance equipment of an embodiment of the present invention includes a support column 10, a rotary column 20 and a hoisting arm 30. The support column 10 serves as a bottom support structure for the offshore hoisting maintenance equipment and is used for being fixed on the deck. The rotating column 20 is disposed in the support column 10 in an axial direction of the support column 10, and is rotatable relative to the support column 10. The lifting arm 30 is connected to the top of the rotary column 20 and rotates with the rotary column 20, so that the lifting arm can rotate according to the direction of the material or equipment to be lifted or the position to be lifted.
The support column 10 is a cylindrical structure, and the hollow passage is used for accommodating the spin column 20. The bottom of the support post 10 is provided with a support flange for locking or welding on the deck by bolts (not shown).
The supporting column 10 is further provided with at least one lifting hole 12 for connecting and lifting the supporting column 10. For example, during installation, the support column 10 is hoisted from the land to the deck and can be disassembled and hoisted back after the completion of the work. A lifting hole 12 is formed through a sidewall of the support post 10, preferably at an upper end of the support post 10, to vertically lift or lower the support post 10.
The rotating column 20 is arranged in the supporting column 10 in a penetrating way, and the axial directions of the rotating column and the supporting column are parallel. The spin column 20 may be a hollow or solid cylindrical structure with an outer diameter smaller than the inner diameter of the support column 10 to facilitate rotation (spinning) within the support column 10. In addition, at least one protruding ring 23 may be disposed on the outer circumference of the rotary column 20 to position the rotary column 20 vertically in the supporting column 10.
The top of the rotary column 20 is provided with a first connecting flange 21, and the first connecting flange 21 is positioned outside the support column 10. The first coupling flange 21 has a diameter greater than the outer diameters of the spin column 20 and the support column 10 so as to radially protrude from the outer circumference of the support column 10. Correspondingly, the bottom of the lifting arm 30 is provided with a second connecting flange 33. The second coupling flange 33 is engaged with the first coupling flange 21 and is lockingly coupled thereto by bolts (not shown), thereby fixedly coupling the lifting arm 30 to the rotary column 20.
In addition, the rotating column 20 is provided with a lifting lug 22 for connecting the lifting and lowering of the rotating column 20, including lifting and lowering of the rotating column 20 from the ground onto the deck, installation into the supporting column 10, and then lifting and lowering thereof after completion of the work. For vertically suspending the rotary column 20, a lifting lug 22 is provided at the top of the rotary column 20, for example, on the first connecting flange 21, specifically the upper surface of the first connecting flange 21, as shown in fig. 2.
The hoisting arm 30 comprises a connecting column 31 parallel to the axial direction of the rotating column 20 and connected to the top of the rotating column 20, and a connecting arm 32 horizontally connected to the top of the connecting column 31. The connection between the connection column 31 and the connection arm 32 makes the hoisting arm 30 have an inverted L shape as a whole.
The connecting column 31 may be a hollow cylindrical structure, reducing the overall weight of the lifting arm 30. After the lifting arm 30 is attached to the rotating column 20, the lifting lug 22 on the top of the rotating column 20 can be received inside the attachment post 31. The second connecting flange 33 is disposed at the bottom of the connecting column 31 and is fitted to the first connecting flange 21.
The connecting arm 32 is perpendicular to the connecting column 31, and one end of the connecting arm 32 is fixed on the top of the connecting column 31 by welding or the like. The connecting arm 32 may be a rectangular body, for example, made of i-steel or the like.
As shown in fig. 2 and 3, the upper surface of the connecting arm 32 is provided with at least one towing point 34 for lifting and towing the lifting arm 30. For example, the lifting arm 30 is lifted from the ground onto the deck, mounted on the rotary column 20, by means of the towing point 34, and can be removed and lifted back after the work is completed; the lifting arm 30 and the rotating column 20 are pulled to rotate and position relative to the supporting column 10 through the pulling point 34.
