Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind power, and in particular to a transition section assembly system and method. Background Art

[0002] At present, large-scale units have become a distinctive feature of the development of offshore wind power. By applying larger-scale wind turbines, the occupation of sea areas can be effectively reduced, the power generation efficiency can be significantly improved, and the cost of installation and construction can be reduced, thereby promoting the reduction of the overall cost of the project. In addition, large-scale conductor frames, due to their superior adaptability, can better cope with complex environmental conditions such as deep sea, providing solid support for the layout of offshore wind power in deep and deep sea areas.

[0003] However, in the process of promoting the large-scale construction of jackets, we inevitably face many challenges and problems, especially in the construction of large jacket foundation structures. Among them, the transition section of the jacket foundation is connected between the wind turbine tower and the jacket body, playing the role of transition connection and load transfer. Due to the structural complexity of the transition section, they usually need to be manufactured separately and then assembled with the main structure of the jacket through lifting equipment. As the size of the jacket increases, the weight of the transition section continues to increase, and the types are becoming increasingly diverse. This undoubtedly puts higher technical requirements on the jacket foundation manufacturers.

[0004] The commonly used transition segment assembly methods include:

[0005] When the conductor frame is horizontal, a movable crane or a fixed crane is used to flip the transition section from a horizontal state to a vertical state, and then the crane is used to connect the transition section with the conductor frame body for assembly.

[0006] When the conductor frame is in a vertical position, the transition section is first lifted by a movable crane or a fixed crane, and then the transition section is docked with the conductor frame body by the crane for assembly.

[0007] That is, the existing transition section assembly methods all require a movable crane or a fixed crane to implement, which has the following problems:

[0008] If it is a mobile crane: First, due to the relatively weak stability of the mobile crane, and the lifting capacity will be significantly reduced when the amplitude increases. Due to the wide variety of transition sections and the heavy weight, in order to adapt to various working conditions, a large-tonnage mobile crane must be configured according to the specific situation. However, the purchase or rental cost of a large-tonnage mobile crane is expensive, which will inevitably increase the cost of equipment purchase or rental. Secondly, when using a mobile crane to perform these tasks, in order to reduce the risk of insufficient lifting capacity due to over-extension of the boom, over-lifting counterweight measures must be implemented. This will inevitably lead to a significant increase in the site area occupied by the crane. In a manufacturing plant environment where land resources are extremely precious, the expansion of the space occupied by the crane directly means a reduction in the operating area, which affects the construction efficiency. Finally, according to the current development trend of the industry, the weight of the transition section is showing an upward trend, but it is difficult for mobile cranes to be updated in time to ensure that their lifting capacity can meet the lifting needs of the transition section.

[0009] If it is a fixed crane: Due to the limitation of the track, its flexibility is low and its operating range is small. Similarly, when the weight of the transition section shows an increasing trend, it is difficult for the fixed crane to be updated in time to ensure that its lifting capacity can meet the lifting needs of the transition section.

[0010] Therefore, the existing method of assembling the transition section by crane has the problem that it cannot take into account high flexibility, low equipment cost, high construction efficiency and wide application range. Summary of the invention

[0011] In order to solve the above problems in the prior art, the present invention provides a transition section assembly system and method, which can simultaneously meet the requirements of high flexibility, low equipment cost, high construction efficiency and wide application range.

[0012] In order to achieve the above object, the technical solution adopted by the present invention is:

[0013] In a first aspect, the present invention provides a transition section assembly system, including a tower crane mechanism and two sets of tower crane walking mechanisms, wherein the tower crane mechanism includes a tower frame, a top connecting beam, a hoisting beam, a first mobile device, a second mobile device and a lifting device;

[0014] Every two towers are located on a group of tower crane traveling mechanisms, and the two towers located on the same tower crane traveling mechanism are connected by a top connecting beam, and two hoisting girders are connected between the two top connecting beams, and two lifting devices are arranged on each hoisting girder;

[0015] The first mobile device is provided with one end on each tower and is connected to the top connecting beam, the second mobile device is located on the hoisting beam and is connected to the fixed end of the lifting device, and the movable end of the lifting device is a sling.

[0016] The beneficial effects of the present invention are: the tower crane mechanism is driven to move by the tower crane walking mechanism, so that the tower crane mechanism is mobile and is not limited by the crane track, so it has a wider walking operation range and higher flexibility. In addition, the two groups of mobile equipment arranged on the tower crane mechanism drive the movement of the lifting equipment, and the movement or flipping of the transition section is realized in combination with the up and down lifting of the lifting equipment, so that it can be docked with a vertical or horizontal conductor frame. Therefore, the cost of using the tower structure is lower than that of various types of cranes, and the floor area is smaller than that occupied by a mobile crane, which increases the operating area and improves the construction efficiency. Therefore, the present invention can simultaneously meet the requirements of high flexibility, low equipment cost, high construction efficiency and wide application range.

[0018] According to the above description, the tower sections are connected by disassembly, so as to meet the construction requirements of different forms of transition sections, and the cost involved is lower than that of various types of cranes.

[0019] Optionally, the tower frame further comprises a tower crane base located at the bottom, and the tower section is located on the tower crane base.

[0020] Optionally, the tower crane traveling mechanism is a modular trolley.

[0021] According to the above description, since modular trolleys are used as the tower crane driving mechanism, when the tower is not used for construction, these modular trolleys can be reallocated to other purposes, thereby improving the economic benefits of the equipment.

[0022] Optionally, the top connecting beam and the two towers are detachably connected.

[0023] According to the above description, the connecting beam at the top of the tower adopts a detachable design, which enables the tower crane mechanism to be decomposed into two independently operated gantry cranes, thereby being able to undertake more construction tasks and improving the efficiency of equipment use.

[0024] Optionally, the second mobile devices are arranged in two groups or four groups. If there are two groups, the two groups of second mobile devices are located on the same side.

[0025] In a second aspect, the present invention provides a transition section assembly method, using a transition section assembly system according to the first aspect, comprising the steps of:

[0026] When the transition section is located below the tower crane mechanism, the lifting device is driven by the first mobile device and the second mobile device to move above the lifting point of the transition section, and the transition section is hung on the lifting device by connecting the sling with the lifting point of the transition section;

[0027] Controlling the lifting device according to the placement form of the corresponding catheter rack so that the transition section and the catheter rack are in the same placement form and have corresponding positions;

[0028] By moving the tower crane's traveling mechanism, the transition section is driven to the conductor frame to complete the docking.

[0029] Optionally, controlling the lifting device according to the placement form of the corresponding jacket so that the transition section and the jacket are in the same placement form and have corresponding positions comprises the following steps:

[0030] When the placement configuration of the catheter rack is a vertical configuration, the lifting device is controlled to lift the transition section to a height higher than the top of the catheter rack.

[0031] Optionally, controlling the lifting device according to the placement form of the corresponding jacket so that the transition section and the jacket are in the same placement form and have corresponding positions comprises the following steps:

[0032] When the catheter rack is placed in a horizontal position, the two first moving devices on the first side control the lifting device on the first side to approach the lifting device on the second side, the lifting device on the first side synchronously lowers the transition section and the lifting device on the second side synchronously raises the transition section, so that the transition section is flipped from a vertical state to a horizontal state, and the docking height of the transition section and the catheter rack is consistent.

[0033] Optionally, when the transition section has three hanging points, two lifting devices on one side are connected to two hanging points of the transition section correspondingly, and one lifting device on the other side is connected to the third hanging point of the transition section correspondingly.

[0034] Among them, the transition segment assembly method provided in the second aspect refers to the relevant description of the transition segment assembly system provided in the first aspect. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0057] Embodiment 1

[0058] Please refer to Figures 1 to 14 The present embodiment provides a transition section assembly system, which is applied to the assembly of offshore wind turbines. Specifically, the transition section assembly system includes a tower crane mechanism 1 and two sets of tower crane walking mechanisms 2. The tower crane mechanism 1 includes a tower frame 11, a top connecting beam 12, a hoisting beam 13, a first mobile device 14, a second mobile device 15 and a lifting device 16.

[0059] Reference Figures 1 to 3 It can be seen that every two towers 11 are located on a group of tower crane traveling mechanisms 2, that is, there are four towers 11 in total. At this time, the two towers 11 located on the same tower crane traveling mechanism 2 are connected by a top connecting beam 12, and two hoisting beams 13 are connected between the two top connecting beams 12. Two lifting devices 16 are arranged on each hoisting beam 13. At this time, the two top connecting beams 12 are parallel to each other, and the two hoisting beams 13 are parallel to each other. A first mobile device 14 is arranged on each tower 11 and corresponds to one end connected to the top connecting beam 12, that is, there are four first mobile devices 14 in total, which are connected to the two ends of the two top connecting beams 12. The second mobile device 15 is located on the hoisting beam 13 and corresponds to the fixed end connected to the lifting device 16. The movable end of the lifting device 16 is a sling 161. In this way, the sling 161 can realize movement in three dimensions, such as up and down, left and right, and front and back. Thus, the first mobile device 14 and the second mobile device 15 drive the four lifting devices 16 to move closer to and farther from each other. On the one hand, the lifting device 16 is moved to align the sling 161 with the lifting point of the transition section 100 to achieve the fixation of the two. On the other hand, when the transition section 100 needs to be assembled with the horizontal conductor frame 200, the transition section 100 is flipped from the initial vertical state to the horizontal state through the movement of the first mobile device 14 and the second mobile device 15, thereby meeting the lifting requirements of different forms of transition sections 100. The above-mentioned matching connection can refer to Figures 6 to 12 .

[0060] In addition, although the transition section 100 has a variety of structures, currently there are usually only four and three lifting points on the transition section 100 for lifting. Fig.13 As shown, when the transition section 100 has four lifting points, four lifting devices 16 are connected at the same time. Fig.14 As shown, when the transition section 100 has three hanging points, two lifting devices 16 on one side are connected to two hanging points of the transition section 100 , and one lifting device 16 on the other side is connected to the third hanging point of the transition section 100 .

[0061] The tower frame 11 includes a plurality of detachably connected tower sections 111 and a tower crane base 112 at the bottom, and the tower sections 111 are located on the tower crane base 112. Therefore, the maximum lifting height of the entire assembly system can be adjusted by increasing or decreasing the number of tower sections 111, so as to meet the construction requirements of different forms of transition sections 100, and the cost involved is lower than that of various types of cranes.

[0062] The top connecting beam 12 is responsible for connecting the two towers 11 and effectively transferring the load from above to the towers 11. At the same time, the top connecting beam 12 and the two towers 11 are detachably connected. Figures 1 to 3 It can be seen that the top connecting beam 12 is connected to the top of the tower 11. At this time, the entire structure is used as a transition section 100 assembly system. Figure 4 and Figure 5 It can be seen that when the top connecting beam 12 is removed and the hoisting beam 13 is moved to the top of the tower 11, the tower crane mechanism 1 is decomposed into two independently operated gantry cranes, so that more construction tasks can be undertaken and the efficiency of equipment use is improved. It should be noted that the detachable connection structure between the top connecting beam 12 and the tower 11 in this embodiment is not fully shown in the figure, and it also includes internal connecting parts and an arch structure, etc., which can increase the overall bearing capacity.

[0063] The hoisting beam 13 is mainly used to connect the two top connecting beams 12 to ensure the effective transfer of the load to the top connecting beams 12 .

[0064] The tower crane travel mechanism 2 is a modular trolley 21, which provides moving power for the tower crane mechanism 1 to ensure that the tower crane obtains necessary support and moving assistance. When the tower 11 is not used for construction, these modular trolleys 21 can be reallocated to other uses, thereby improving the economic benefits of the equipment.

[0065] In this embodiment, four groups of second mobile devices 15 are provided, so that the four lifting devices 16 can be moved. Relatively speaking, when the transition section 100 is hoisted, its bearing position can be close to the center position to ensure the overall stability. In other embodiments, two groups of second mobile devices 15 are provided. In this case, the two groups of second mobile devices 15 are located on the same side, and the two groups of second mobile devices 15 on the other side are fixed. In this case, it is necessary to fix them in a suitable position according to the operating range of the transition section 100 to avoid the problem of weight tilting to one side and causing unstable hoisting.

[0066] For the specific coordination process between a transition segment assembly system and the transition segment 100 of this embodiment, please refer to the second embodiment.

[0067] Embodiment 2

[0068] Please refer to Fig.15 The present embodiment provides a transition segment assembly method, combined with a transition segment assembly system of the first embodiment and a reference Figures 1 to 14 , the assembly method includes the steps of:

[0069] S1. When the transition section 100 is located below the tower crane mechanism 1, the first mobile device 14 and the second mobile device 15 drive the lifting device 16 to move above the lifting point of the transition section 100, and the transition section 100 is hung on the lifting device 16 by connecting the sling 161 with the lifting point of the transition section 100.

[0070] Before the transition section 100 is located below the tower crane mechanism 1, the following steps are also included:

[0071] Manufacturing stage: Based on the construction detailed drawings, the raw materials are processed into the transition section 100 by cutting, welding, painting and other process methods.

[0072] Moving stage: the processed transition section 100 is transported to the bottom of the tower crane mechanism 1 by means of a transport tool, or the tower crane mechanism 1 is moved to the top of the transition section 100 driven by the tower crane traveling mechanism 2 .

[0073] S2. Control the lifting device 16 according to the placement of the corresponding catheter rack 200, so that the transition section 100 and the catheter rack 200 are in the same placement and at corresponding positions.

[0074] In this embodiment, step S2 includes the following steps:

[0075] S21 . When the jacket 200 is placed in a vertical position, the lifting device 16 is controlled to lift the transition section 100 to a height higher than the top of the jacket 200 .

[0076] At this time, the transition section 100 is in a vertical state by default, that is, when the catheter rack 200 is placed in a vertical state, the two do not need to have the same placement form, so it is only necessary to raise the height of the transition section 100 higher than the top of the catheter rack 200 so that it can be connected with the catheter rack 200 up and down.

[0077] S22. When the placement configuration of the catheter rack 200 is a horizontal configuration, the two first moving devices 14 on the first side control the lifting device 16 on the first side to approach the lifting device 16 on the second side, the lifting device 16 on the first side synchronously lowers the transition section 100 and the lifting device 16 on the second side synchronously raises the transition section 100, so as to complete the flipping of the transition section 100 from a vertical state to a horizontal state, and make the docking height of the transition section 100 and the catheter rack 200 consistent.

[0078] At this time, the transition section 100 is in a vertical state by default, that is, when the catheter rack 200 is placed in a horizontal state, the two need to have the same placement state, so the transition section 100 needs to be turned over and adjusted in height first, and then it needs to be docked with the catheter rack 200 left and right.

[0079] S3. The tower crane traveling mechanism 2 moves to drive the transition section 100 to the conductor frame 200 to complete the docking.

[0080] Therefore, when the placement form of the catheter rack 200 is a vertical form, the assembly process of the transition section 100 and the catheter rack 200 is as follows: Figures 6 to 8 It can be seen that: first, the transition section 100 in step S1 is located below the tower crane mechanism 1, secondly, the height of the transition section 100 in step S2 is higher than the top of the jacket 200, and finally, the transition section 100 in step S3 is moved to the top of the jacket 200 to complete the docking. When the jacket 200 is placed in a horizontal form, the assembly process of the transition section 100 and the jacket 200 is referred to Figure 6 , Figures 9 to 11 It can be seen that: first, the transition section 100 in step S1 is located below the tower crane mechanism 1, then the transition section 100 is turned over in step S2, then the transition section 100 in step S2 is turned over to a horizontal state, and finally the transition section 100 in step S3 is moved to the side of the jacket 200 to complete the docking. Therefore, this embodiment can be docked with a vertical or horizontal jacket 200.

[0081] Finally, after the transition section 100 and the catheter frame 200 are butt-jointed, the transition section 100 and the catheter frame 200 are assembled by welding or other assembly works.

[0082] It can be seen from the above embodiments that the present invention has the following advantages:

[0083] (1) The tower crane mechanism 1 is driven to move by the tower crane traveling mechanism 2, thereby realizing the mobility of the tower crane mechanism 1 and being free from the restriction of the crane track, thus having a wider traveling operation range and higher flexibility.

[0084] (2) By adjusting the height of the tower 11 and the position of the suspension point, it can be docked with a vertical or horizontal conductor frame 200, thereby increasing the scope of application. Therefore, the cost of using the tower 11 structure is lower than that of various types of cranes.

[0085] (3) Under the premise of the same lifting weight, the floor space occupied by the tower 11 structure is smaller than that occupied by the mobile crane, which increases the working area and improves the construction efficiency.

[0086] (4) The modular trolley 21 can be reallocated to other uses, thereby improving the economic benefits of the equipment.

[0087] (5) The connecting beam at the top of the tower frame 11 is designed to be detachable, so that the tower crane mechanism 1 can be decomposed into two independently operated gantry cranes, thereby being able to undertake more construction tasks and improving the efficiency of equipment use.

[0088] That is, the present invention can simultaneously meet the requirements of high flexibility, wide application range, low equipment cost, high construction efficiency, high economic benefit and high utilization efficiency.
