Referring to fig. 1, in a first aspect, the present application provides a lifting apparatus assembly for mounting a turret 20 on a semi-submersible 40. Illustratively, FIG. 1 shows a lifting device assembly in one example, and illustrates the relative positional relationship of the turret 20 and the semi-submersible 40. The hoisting equipment assembly comprises a hoisting device 11 and an assembling mechanism 12 which are arranged on a slipway 10, the slipway 10 is positioned on land and is provided with a berthing wharf 13, the berthing wharf is provided with a crane ship 30, and a tower 20 can be hoisted by the crane ship 30 on the berthing wharf 13. The deck of the hull of the semi-submersible 40 is generally rectangular, and each of the four corner positions of the semi-submersible 40 is provided with a turret 20. The turret 20 is first constructed at the slipway 10 and then hoisted to the hull of the semi-submersible 40 using the crane vessel 30 to complete the installation. The semi-submersible barge 40 rests on the outfitting terminal 50, and the outfitting terminal 50 is spaced from the berthing terminal 13 so that the crane vessel 30 can move between the outfitting terminal 50 and the berthing terminal 13.
As an example, referring to fig. 5 to 6, the assembly mechanism 12 includes a hydraulic vehicle 120, a first moving bracket 121, a second moving bracket 122, and a rail 123, the rail 123 extends to the berth terminal 13, the hydraulic vehicle 120 is disposed at the bottoms of the first moving bracket 121 and the second moving bracket 122, and the hydraulic vehicle 120 drives the first moving bracket 121 and the second moving bracket 122 to move along the rail 123.
Specifically, the tower 20 includes a first tower section 21 and a second tower section 22, the first tower section 21 and the second tower section 22 are disposed on the berth 10, the berth 10 is provided with a hoisting device 11 and an assembling mechanism 12, the hoisting device 11 may be a gantry crane, and the assembling mechanism 12 extends to the berth terminal 13.
Referring to fig. 1 to 3, in a second aspect, the present application further provides a method for hoisting a tower, including the following steps:
s1, respectively hoisting a first tower section and a second tower section by a hoisting device and placing the first tower section and the second tower section on an assembling mechanism;
s2, assembling the first tower section and the second tower section in an assembling mechanism to form a third tower section;
s3, conveying the third tower section to a berthing wharf by an assembling mechanism;
s4, hoisting the third tower section to a semi-submerged barge by the crane ship.
By providing the assembly mechanism 12, the first tower segment 21 and the second tower segment 22 can be assembled to form the third tower segment 23, that is, the tower 20 can be hoisted to the semi-submerged barge 40 by means of first manufacturing in sections and then assembling and transporting. By means of the assembly mechanism 12, on the one hand, when the lifting device 11 lifts the first tower section 21 and the second tower section 22 respectively, the weight of any one of the first tower section 21 and the second tower section 22 does not exceed the maximum lifting weight of the lifting device 11, so that the problem of insufficient lifting capacity of the lifting device 11 can be solved. On the other hand, the third tower section 23 is transported to the berthing terminal 13 by the assembly mechanism 12, so that the tower 20 is hoisted from the slipway 10 to the semi-submerged barge 40, the distance between the tower 20 and the semi-submerged barge 40 can be shortened, and the transportation efficiency of the tower 20 is improved. The splicing function and the transportation function of the splicing mechanism 12 are utilized to multiplex, and the occupied area of the splicing mechanism 12 on the slipway 10 can be reduced, so that the space of the slipway 10 is saved.
Since the first tower section 21 and the second tower section 22 also have a large volume and weight, the sectional manufacturing of the first tower section 21 or the second tower section 22 can simplify the manufacturing process. Referring to fig. 4, in some embodiments, the first tower section 21 includes at least two first tower blocks 210, the second tower section 22 includes at least two second tower blocks 220, the berth 10 further includes a tower assembly area 14, and the first tower blocks 210 and the second tower blocks 220 are disposed in the tower assembly area 14. Illustratively, the first tower section 21 may be spliced from 2 to 3 first tower blocks 210, and the second tower section 22 may be spliced from 2 to 3 second tower blocks 220. Based on this, before step S1, the hoisting method further comprises the steps of:
s0. the first tower blocks are assembled in the tower assembling area to form a first tower section, and the second tower blocks are assembled in the tower assembling area to form a second tower section.
After the plurality of first tower blocks 210 are assembled to form the first tower section 21 by adopting the method, the first tower section 21 is hoisted by using the hoisting device 11, so that the operation times of the hoisting device 11 can be reduced on the premise of ensuring that the weight of the first tower section 21 does not exceed the maximum hoisting weight of the hoisting device 11, and the operation times of the crane ship 30 can be reduced, thereby improving the hoisting efficiency of the tower 20. Similarly, the number of operations of the hoisting device 11 and the crane vessel 30 can be reduced by assembling a plurality of second tower blocks to form the second tower section 22. The greater the number of first tower blocks 210, the closer the weight of the first tower segment 21 formed by the assembly can be to the maximum lifting weight of the lifting device 11, so that the number of operations of the lifting device 11 can be reduced. In the actual construction process, the number of the first tower blocks 210 and the second tower blocks depends on the specific weight of each first tower block 210 and the second tower block and the maximum lifting weight of the lifting device 11.
Illustratively, in the step S0, only the first tower block 210 may be assembled, and the second tower block 220 is not assembled, and the second tower block 220 is directly assembled with the first tower segment 21; or only the second tower block 220 is assembled, while the first tower block 210 is not assembled, and the first tower block 210 and the second tower segment 22 are directly assembled. Of course, the first tower segment 21 and the second tower segment 22 may be assembled after the first tower blocks 210 and the second tower blocks 220 are assembled.
The splicing mechanism 12 can be used for splicing and transporting the first tower section 21 and the second tower section 22, specifically, the above step S1 includes the steps of:
s11, lifting the first tower section by the lifting device and placing the first tower section on the first movable support, and lifting the second tower section by the lifting device and placing the second tower section on the second movable support.
The first moving support 121 and the second moving support 122 are utilized to respectively support the first tower section 21 and the second tower section 22, and the hydraulic vehicle 120 is used for bearing the first moving support 121 and the second moving support 122 to move so as to drive the first tower section 21 and the second tower section 22 to move relatively, so that the first tower section 21 and the second tower section 22 can be conveniently adjusted to a proper position for assembly. The rail 123 can provide route guidance for the movement of the hydraulic vehicle 120, avoid the yaw of the hydraulic vehicle 120, enable the movement track of the hydraulic vehicle 120 to be more accurate, and improve the transportation efficiency of the hydraulic vehicle 120.
Specifically, the slipway 10 further includes a turret assembly area 14, the first turret section 21 and the second turret section 22 are disposed in the turret assembly area 14, and before the first turret section 21 and the second turret section 22 are respectively lifted by the lifting device 11 and placed on the first moving bracket 121 and the second moving bracket 122, the method for lifting a turret further includes the following steps:
s01, paving a rail, wherein one end of the rail is arranged corresponding to the tower splicing area, and the other end of the rail extends to the berthing wharf.
By laying the rail 123 in the above manner, the transportation distance between the first tower section 21 and the second tower section 22 can be shortened to a large extent. Illustratively, the rail 123 adopts a linear rail manner, and the first tower segment 21 and the second tower segment 22 can reach the berthing terminal 13 through a shorter path after the assembly of the tower assembly area 14 is completed, so that the time waste in the transportation process is reduced, and the transportation efficiency is improved.
In some embodiments, the first moving support 121 and the second moving support 122 are in a grid structure, and the hydraulic vehicles 120 are multiple, and the multiple hydraulic vehicles 120 are respectively arranged in grid nodes of the first moving support 121 and the second moving support 122. The movable support is arranged into a grid structure, so that materials can be saved on the premise of ensuring the bearing capacity of the movable support, the self weight of the movable support is reduced, and the occupation of the carrying capacity of the hydraulic vehicle 120 is reduced. The positions of the plurality of hydraulic vehicles 120 corresponding to the grid nodes are set, so that the weights of the first movable support 121, the second movable support 122, the first tower section 21 and the second tower section 22 can be uniformly dispersed, and the stability and the safety of the assembly mechanism 12 in the process of assembling and transporting the first tower section 21 and the second tower section 22 are improved.
Specifically, the step S2 includes the steps of:
s21, moving the hydraulic vehicle, and driving the first moving support and the second moving support to approach each other so as to enable the first tower section to be in butt joint with the second tower section;
s22, welding the first tower section and the second tower section.
The hydraulic vehicle 120 is guided to move by the rail 123, so that the movement and the butt joint of the first tower section 21 and the second tower section 22 can be realized, and the alignment precision when the first tower section 21 and the second tower section 22 are in butt joint can be improved. After the first tower section 21 and the second tower section 22 are welded, the connection strength of the first tower section and the second tower section can be improved, and a larger third tower section 23 structure is formed. The third tower section 23 can be hoisted to the semi-submerged barge 40 at one time by using the crane ship 30, so that the operation times of the crane ship 30 are reduced, and the hoisting construction efficiency is improved.
When the overall weight of the turret 20 is large, the turret 20 may also be divided into fourth turret sections 24, and thus, in some embodiments, the turret 20 further comprises fourth turret sections 24, the fourth turret sections 24 being arranged at the slipway 10. After the crane vessel 30 has hoisted the third turret section 23 to the semi-submersible barge 40, the turret hoisting method further comprises the steps of:
s51, hoisting the fourth tower section to the top of the third tower section by a crane ship;
s52, welding the third tower section and the fourth tower section.
By adopting the mode to set the fourth tower section 24, the number of tower sections can be reduced on the premise that the weight of any one of the first tower section 21, the second tower section 22 and the fourth tower section 24 does not exceed the maximum lifting weight of the lifting device 11, so that the operation times of the lifting ship 30 are reduced.
Specifically, before step S51, the hoisting method of the tower includes the following steps:
s501, lifting the fourth tower section by a lifting device and placing the fourth tower section on an assembling mechanism;
s502, conveying the fourth tower section to a berthing wharf by the assembly mechanism.
The fourth turret section 24 is also lifted by the lifting device 11 and placed on the assembly machine 12, so that the fourth turret 20 can be carried by the transportation function of the assembly machine 12, that is, by using the first moving bracket 121 (or the second moving bracket 122), and the hydraulic vehicle 120 drives the first moving bracket 121 to move under the guiding action of the rail 123, so that the crane ship 30 can lift the fourth turret section 24 at the berthing terminal 13.
In some embodiments, because the tower 20 has a higher height, in order to reduce overhead operations and improve manufacturing efficiency, the tower 20 or tower sections are usually manufactured with one of the sides as a bottom, and are turned over after being manufactured, so that they are in an upright state, i.e. in a state when put into use. Therefore, before the first tower section 21 and the second tower section 22 are assembled, they need to be turned over separately.
Specifically, before step S2, the hoisting method of the tower further includes the following steps:
s20, the first tower section is overturned by the lifting device so that the top surface of the first tower section faces upwards, and the second tower section is overturned by the lifting device so that the top surface of the second tower section faces upwards.
Referring to fig. 7, fig. 7 (a), (b) and (c) show the turning process of the first tower section 21 (or the second tower section 22), that is, the first tower section 21 can be turned from the side lying state (fig. 7 (a)) to the standing state (fig. 7 (c)) via the lifting device 11.
The first tower section 21 and the second tower section 22 are assembled and turned over before being assembled, so that the whole weight of the third tower section 23 can be prevented from exceeding the maximum turning-over weight of the lifting device 11, and the smooth turning-over of the tower sections is ensured. On the other hand, the first tower section 21 and the second tower section 22 are smaller in weight and volume before assembly, and the operation difficulty of the turning operation can be reduced by turning the first tower section and the second tower section, so that the safety and reliability of the turning operation are improved.
In some embodiments, referring to fig. 8, since the height of the first tower section 21 or the second tower section 22 after turning over is higher, the center of gravity of the first tower section 21 and the second tower section 22 after turning over is higher than that of the first tower section 21 and the second tower section 22 in the side lying state, so that auxiliary stability measures are required to ensure stability and safety of the first tower section 21 and the second tower section 22 during assembling. Specifically, after step S20, the hoisting method of the tower further includes the following steps:
s21, a supporting structure is arranged, one end of the supporting structure is connected to the outer circumferential side face of the first tower section or the second tower section, and the other end of the supporting structure is connected to the assembling mechanism.
The supporting structure 124 may be a rod-shaped structure or a plate-shaped structure, and a triangle structure is formed by the supporting structure 124 and the outer peripheral side surface of the first tower section 21 (or the second tower section 22) and the upper surface of the assembly mechanism 12, so that the first tower section 21 is beneficial to being firmly fixed, the first tower section 21 is prevented from shaking or collapsing in the moving or assembling process, and the stability of the first tower section 21 and the second tower section 22 in the assembling and transporting process is improved. Illustratively, the support structure 124 may be temporarily fixedly coupled to the first turret section 21 or the assembly mechanism 12 by bolting, welding, or the like. After the first tower segment 21 and the second tower segment 22 are assembled, the supporting structure 124 is not removed, so that the auxiliary stability of the third tower segment 23 is kept during the transportation to the berthing terminal 13. Until the third tower section 23 is lifted by the crane vessel 30, the support structure 124 may be removed to facilitate separation of the third tower section 23 from the racking mechanism 12.
In summary, by adopting the scheme of the application, the first tower section 21 and the second tower section 22 positioned in the tower splicing area 14 of the slipway 10 can be spliced by the splicing mechanism 12, transported to the berthing wharf 13 by the splicing mechanism 12 and hoisted to the semi-submerged barge 40 by the crane ship 30 to finish the installation. The above operation is repeated until the hoisting of the 4 turrets 20 at the four corners of the semi-submersible 40 is completed.
