Abstract
Description
Technical Field
[0001] This application relates to the field of offshore lifting equipment, and in particular to a special lifting equipment for a detachable offshore booster station superstructure module. Background Technology
[0002] The upper module of the offshore substation is the core component of the offshore substation, mainly responsible for collecting and boosting the voltage of the electricity generated by offshore wind turbines, and then transmitting it to the onshore power grid via submarine cables. As a connecting bridge between offshore wind farms and onshore power grids, the upper module of the offshore substation plays a vital role.
[0003] The superstructure of offshore substations is typically installed using a hoisting method, which usually involves direct hoisting using slings and ropes. However, due to the uneven weight distribution of the internal equipment within the superstructure, there is often a problem of weight eccentricity. This makes it difficult to maintain a stable horizontal position for the main hook during hoisting, increasing instability and hindering the stable hoisting of the substation superstructure. Utility Model Content
[0004] To facilitate the stable hoisting of the upper modules of offshore substations, this application provides a detachable lifting tool specifically designed for the upper modules of offshore substations.
[0005] The technical solution provided in this application for a special lifting tool for the upper module of a detachable offshore substation is as follows:
[0006] A detachable lifting tool for the upper module of an offshore substation includes a hook and a lifting tool body. The hook has four hook-holding parts. The lifting tool body includes two lifting beams and two load-bearing beams. The two lifting beams are arranged in parallel. The two ends of the two lifting beams near their own length are respectively connected to the four hook-holding parts by connecting ring slings. The two load-bearing beams are arranged in parallel and fixedly installed at the bottom of the two lifting beams. The two ends of the two load-bearing beams near their own length are provided with lifting ring slings for lifting the workpiece.
[0007] By adopting the above technical solution, during the hoisting of the upper module of the offshore substation, four hoisting ring slings are directly connected to the upper module. Then, the hook is hoisted so that the hook, through the lifting device body, drives the workpiece, i.e., the entire upper module of the offshore substation, to be hoisted together. The design of the lifting device body can evenly distribute stress during the hoisting of the upper module of the offshore substation, thereby enabling the upper module of the offshore substation to maintain better balance during the hoisting process, reducing the risk of swaying and tilting, which is conducive to improving the overall hoisting stability and facilitating the stable hoisting of the upper module of the offshore substation.
[0008] Optionally, a connecting beam is provided between the hoisting beam and the load-bearing beam. There are four connecting beams arranged in a rectangular shape, with one end of each connecting beam fixedly installed to the hoisting beam and the other end fixedly installed to the load-bearing beam.
[0009] By adopting the above technical solution, the setting of the connecting beam makes it less likely for the connecting ring sling and the hoisting ring sling to interfere with each other during the hoisting process, which is conducive to further ensuring the stability of the workpiece, namely the upper module of the offshore substation, during hoisting.
[0010] Optionally, both the lifting beam and the load-bearing beam are composed of multiple beams, with adjacent beams designated as a first beam and a second beam, respectively, and the first beam and the second beam are fixed together by bolts.
[0011] By adopting the above technical solution, the lifting beam and load-bearing beam composed of multiple beams enable the individual beam to be removed for maintenance and replacement when it is damaged, which facilitates the subsequent maintenance of the lifting beam and load-bearing beam and ensures its performance.
[0012] Optionally, a first flange is fixedly connected to one end of the first beam facing the second beam, and a second flange is fixedly connected to one end of the second beam facing the first beam. The first flange and the second flange are fixedly connected by bolts. A positioning block is fixedly connected to one side of the first flange facing the second flange, and a positioning hole corresponding to and engaging with the positioning block is provided on one side of the second flange facing the first flange.
[0013] By adopting the above technical solution, the setting of the first flange and the second flange facilitates the stable connection between the first beam and the second beam. The cooperation of the positioning block and the positioning hole plays a positioning role during the installation of the first beam and the second beam, which helps to ensure the stress stability of the first beam and the second beam during installation.
[0014] Optionally, a first reinforcing rib is fixedly connected between the first flange and the first beam, and a second reinforcing rib is fixedly connected between the second flange and the second beam, and the ...
[0015] By adopting the above technical solution, the setting of the first reinforcing rib and the second reinforcing rib helps to ensure the connection strength between the first flange and the first beam and the second flange and the second beam, respectively, thereby fully ensuring the structural strength of the hoisting beam and the load-bearing beam and improving the load-bearing capacity.
[0016] Optionally, the hook is provided with a limiting component, which includes a limiting block, a limiting rod, and a limiting spring. The hook holding part is provided with a limiting groove extending in the radial direction of the hook. The limiting block is slidably fitted in the limiting groove. The limiting rod is fixedly installed on the limiting block and passes through the hook in the radial direction of the hook and is slidably fitted in the hook holding part. The limiting spring is used to move the limiting block away from the hook holding part. One end of the lifting ring sling is located at the bottom of the limiting block.
[0017] By adopting the above technical solution, the limiting block further limits the position of the lifting ring sling, making it difficult for the lifting ring sling to fall off the hook. This helps to further ensure the stability of the lifting ring sling when lifting the lifting device body. Pulling the limiting rod to move the limiting block closer to the hook releases the limitation on the lifting ring sling, making it easier and faster to remove the lifting ring sling.
[0018] Optionally, a limiting guide surface is provided on the top of the limiting block, and the limiting guide surface moves toward the hook portion when subjected to force.
[0019] By adopting the above technical solution, the limiting guide surface plays a guiding role during the installation of the hoisting ring sling, making it easy to quickly install the hoisting ring sling to the position where it is connected to the hook and located at the bottom of the limiting block.
[0020] Optionally, a limit handle is fixedly connected to the end of the limit rod away from the limit block.
[0021] By adopting the above technical solution, the setting of the limit handle makes it convenient and stable for workers to apply force to achieve the movement of the limit rod.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. The design of the lifting gear body can evenly distribute stress during the hoisting of the upper module of the offshore substation, thereby enabling the upper module of the offshore substation to maintain better balance during the hoisting process, reducing the risk of swaying and tilting, which is conducive to improving the overall hoisting stability and facilitating the stable hoisting of the upper module of the offshore substation.
[0024] 2. The connecting beam design makes it less likely for the connecting ring sling and the hoisting ring sling to interfere with each other during the hoisting process, which helps to further ensure the stability of the workpiece, namely the upper module of the offshore substation, during hoisting.
[0025] 3. The lifting beam and load-bearing beam, composed of multiple beams, allow for the removal and replacement of individual beams in case of damage, facilitating subsequent maintenance of the lifting beam and load-bearing beam and ensuring their performance. Attached Figure Description

Detailed Implementation
[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0032] This application discloses a special lifting tool for a detachable offshore substation upper module. (Refer to...) Figure 1 and Figure 2 The special lifting tool for the detachable offshore substation upper module includes a hook 1 and a lifting tool body 2. The hook 1 includes a base plate 101, a hook holding part 102, and a stop part 103.
[0033] Reference Figure 2 In this embodiment, the base plate 101 is circular. Four hook-holding parts 102 are fixedly installed on the top of the base plate 101 and are evenly distributed circumferentially around the axis of the base plate 101. Four stop parts 103 are also fixedly installed on the top of the base plate 101 and are evenly distributed circumferentially around the axis of the base plate 101. Each stop part 103 is close to the axis of the base plate 101 and is directly opposite to each hook-holding part 102. A connecting ring strap 3 is provided between each stop part 103 and each hook-holding part 102 to achieve a stable connection with the lifting device body 2.
[0034] Continue to refer to Figure 2To further ensure the stability of the position of the connecting ring sling 3, the hook part 102 is provided with a limiting component, which includes a limiting block 4, a limiting rod 5, and a limiting spring 6. The free end of the hook part 102 near its top has a limiting groove 7 extending radially along the bottom plate 101. The limiting groove 7 extends to the side of the hook part 102 near the stop part 103. The limiting block 4 slides and fits in the limiting groove 7. One end of the limiting spring 6 is fixedly installed on the limiting block 4, and the other end is fixedly installed on the groove wall of the limiting groove 7 away from the stop part 103. Under the elastic force of the limiting spring 6, the limiting block 4 abuts against the top of the stop part 103, thereby achieving stable limiting of the position of the connecting ring sling 3.
[0035] Continue to refer to Figure 2 The top of the limiting block 4 is provided with an arc-shaped limiting guide surface 8. When the limiting guide surface 8 is subjected to force, it moves towards the hook part 102, thereby facilitating the quick placement of the connecting ring sling 3 between the stop part 103 and the hook part 102. One end of the limiting rod 5 is fixedly installed on the limiting block 4, and the other end passes through the radial direction of the base plate 101 and slides to engage with the hook part 102, so that by pulling the limiting rod 5, the limiting block 4 moves together, thereby releasing the limitation on the position of the connecting ring sling 3. The end of the limiting rod 5 away from the limiting block 4 is fixedly connected to a limiting handle 9, so that the movement of the limiting rod 5 can be achieved by applying force through the limiting handle 9.
[0036] Reference Figure 1 and Figure 3 The lifting device body 2 includes two lifting beams 201 and two load-bearing beams 202. The two lifting beams 201 are arranged in parallel. Lifting wheels 10 are rotatably installed at both ends of the two lifting beams 201 near their own length direction. The end of each connecting ring sling 3 away from each hook 102 is respectively wrapped around each lifting wheel 10 to achieve a stable connection between the lifting beams 201 and the hooks 1.
[0037] Reference Figure 3 Two load-bearing beams 202 are arranged in parallel and are located at the bottom of two lifting beams 201. The two load-bearing beams 202 and the two lifting beams 201 form a rectangle. Load-bearing wheels 11 are rotatably installed at both ends of the two load-bearing beams 202 near their own length direction. The load-bearing wheels 11 are wrapped with lifting ring slings 12 to stably lift the workpiece, namely the upper module of the offshore substation.
[0038] Reference Figure 1 and Figure 3To prevent interference between the lifting ring sling 12 and the connecting ring sling 3, and to further ensure the stability of the workpiece during lifting, a connecting beam 13 is provided between the lifting beam 201 and the load-bearing beam 202. There are four connecting beams 13 arranged in a rectangle. One end of each connecting beam 13 is fixedly installed on the lifting beam 201 and the other end is fixedly installed on the load-bearing beam 202, so as to achieve a stable connection between the lifting beam 201 and the load-bearing beam 202.
[0039] Continue to refer to Figure 1 and Figure 3 To facilitate subsequent inspection and maintenance of the lifting beam 201 and the load-bearing beam 202, both the lifting beam 201 and the load-bearing beam 202 are composed of multiple beams 14. Specifically, two adjacent beams 14 are respectively designated as a first beam 141 and a second beam 142. A first flange 15 is fixedly connected to the end of the first beam 141 facing the second beam 142, and a second flange 16 is fixedly connected to the end of the second beam 142 facing the first beam 141. The first flange 15 and the second flange 16 are fixed by bolts evenly distributed around their own axes to achieve a stable connection between the first flange 15 and the second flange 16.
[0040] Reference Figure 3 To ensure the stability of the position of the first flange 15 and the second flange 16 when they are fixed by bolts, a number of positioning blocks 17 are fixedly connected to the side of the first flange 15 facing the second flange 16, which are evenly distributed around their own axis. In this embodiment, the positioning blocks 17 are cylindrical, and the positioning blocks 17 are staggered with the bolts that fix the first flange 15 and the second flange 16. The side of the second flange 16 facing the first flange 15 has positioning holes 18 that correspond to the positioning blocks 17 and are inserted into the positioning blocks 17, so as to play a stable positioning role when the first flange 15 and the second flange 16 are connected.
[0041] Continue to refer to Figure 3 A first reinforcing rib 19 is fixedly connected between the first flange 15 and the first beam 141, and a second reinforcing rib 20 is fixedly connected between the second flange 16 and the second beam 142, and a second reinforcing rib 20 is fixedly connected between the second flange 16 and the second beam 142, and a second reinforcing rib 20 is fixedly connected between the second flange 16 and the second beam 142, so as to ensure the overall structural strength of the hoisting beam 201 and the load-bearing beam 202, thereby achieving stable load bearing on the upper module of the offshore substation.
[0042] The implementation principle of a detachable lifting tool for the upper module of an offshore substation according to an embodiment of this application is as follows: When it is necessary to lift the upper module of the offshore substation, four lifting ring slings 12 are first directly connected to the upper module of the offshore substation. Then, the lifting hook 1 is lifted so that the lifting hook 1 drives the workpiece, i.e., the entire upper module of the offshore substation, through the lifting tool body 2. The lifting tool body 2 can evenly distribute stress when lifting the upper module of the offshore substation, so that the upper module of the offshore substation can better maintain balance during the lifting process, reduce the risk of swaying and tilting, improve the overall lifting stability, and facilitate the stable lifting of the upper module of the offshore substation.
[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
