Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, specifically a hoisting auxiliary device for offshore wind power construction. Background Technology

[0002] Offshore wind energy benefits significantly from the lack of obstructions such as terrain and buildings on the vast ocean surface, resulting in less energy loss during wind flow, higher and more stable wind speeds, and thus significantly higher energy efficiency than onshore wind power. The structure of offshore wind turbines is similar to that of onshore wind turbines, primarily consisting of underwater support foundations, towers, nacelles, transmission systems, and large turbine blades. However, these components are typically extremely large and heavy; for example, a single blade can be tens of meters long and weigh tens of tons. Therefore, in the complex construction environment at sea, the transportation and installation process heavily relies on large floating cranes and specialized lifting auxiliary equipment to achieve precise and safe lifting and positioning operations.

[0003] Despite abundant offshore wind energy resources, construction often faces harsh sea conditions and weather, especially unstable and strong sea winds. During hoisting, the large size, heavy weight, and wide windward area of ​​the hoisted object make it prone to significant swaying in the wind. This swaying is transmitted through the hoisting ropes to the hook and crane boom, creating a complex swaying effect. This not only seriously threatens hoisting accuracy and efficiency but also easily leads to accidental collisions between precision components or with the installed structure, causing scratches on the equipment's surface coating, damage to the internal structure, or even permanent destruction. At the same time, the violent swaying greatly increases the operational risks, posing a serious threat to the safety of on-site personnel and equipment.

[0004] Based on this, a hoisting auxiliary device for offshore wind power construction is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] Example 1

[0029] In one embodiment, such as Figures 1-8 As shown, a hoisting auxiliary device for offshore wind power construction includes a lifting beam 11 and a tower body 16. The upper end of the lifting beam 11 is fixedly connected to one end of two steel cables 12, which are wound inside two winch components 13. Both winch components 13 are fixedly installed at the bottom of the interior of a first moving trolley 14. Rollers are symmetrically arranged on the upper inner side of the first moving trolley 14, and the rollers are installed in guide grooves on the upper end of a top frame 15. The top frame 15 is fixedly installed on the upper end of the tower body 16. The upper inner end of the first moving trolley 14 is fixedly connected to the upper end of a first transmission belt 22 via a fixing plate. Both ends are equipped with first transmission rollers, and first support frames are rotatably provided on the outer side of each first transmission roller. The two first support frames are respectively fixed on one end of the top frame 15 and the upper end of the fixing plate 27. The fixing plate 27 is fixed on the inner side of the top frame 15 and is located above the tower body 16. The other end of the top frame 15 is equipped with a counterweight mechanism for counterweighting. The bottom of the first moving trolley 14 is equipped with an anti-sway mechanism to prevent the lifting beam 11 from swaying. The counterweight mechanism facilitates the adjustment of the counterweight position according to the moving distance of the first moving trolley 14. The anti-sway mechanism facilitates the prevention of large swaying of the lifting beam 11 during hoisting.

[0030] The tower body 16 is fixedly provided with a base frame 17 at the bottom end. The base frame 17 is symmetrically provided with walking components 18 at the bottom end. In use, the tower body 16 is moved by the walking components 18, which facilitates the transfer of materials. At the same time, the walking components 18 in this application are existing components, which will not be described in detail here.

[0031] A first bevel gear is fixedly mounted on a rotating shaft at one end of the first transmission roller. A second bevel gear meshes with the first bevel gear. The second bevel gear is fixedly mounted on the output end of the first reducer 28. A third bevel gear is fixedly mounted on the input end of the first reducer 28. A fourth bevel gear meshes with the third bevel gear. The fourth bevel gear is fixedly mounted on one end of a fixed shaft. Rotating plates are rotatably mounted at both ends of the fixed shaft. The rotating plates are fixedly mounted on the upper end of a fixed plate 27. A first gear is fixedly mounted on the fixed shaft. A second gear meshes with the first gear. The second gear is fixedly mounted on a first electric... At the output end of the motor 30, both the first reducer 28 and the first motor 30 are fixedly mounted on the upper end of the fixed plate 27. In use, when the first moving trolley 14 needs to move on the upper end of the top frame 15, the first motor 30 is started. The output end of the first motor 30 drives the fixed shaft to rotate, the fixed shaft drives the input end of the first reducer 28 to rotate, and the output end of the first reducer 28 drives the first transmission roller to rotate. The two first transmission rollers cooperate to drive the first transmission belt 22 to rotate. Since the first transmission belt 22 is fixedly connected to the first moving trolley 14, the first transmission belt 22 drives the first moving trolley 14 to move on the upper end of the top frame 15.

[0032] The counterweight mechanism includes a counterweight box 25, which is fixedly mounted at the bottom of the second moving trolley 23. The counterweight box 25 contains several counterweight blocks 26. The second moving trolley 23 is slidably mounted on the upper end of the top frame 15. The upper end of the interior of the second moving trolley 23 is fixedly connected to the upper end of the second transmission belt 24 via a fixing plate. Second transmission rollers are fitted at both ends of the second transmission belt 24. Second support frames are rotatably mounted on the outer sides of each of the second transmission rollers. Two second support frames are respectively fixedly mounted at one end of the top frame 15 and the upper end of the fixing plate 27. A fifth bevel gear is fixedly mounted on the rotating shaft at one end of one of the second transmission rollers. A sixth bevel gear meshes with the fifth bevel gear. The sixth bevel gear is fixedly mounted on the output end of the second reducer 29. A seventh bevel gear is fixedly mounted on the input end of the second reducer 29. An eighth bevel gear is meshed on the wheel and fixedly mounted on the other end of the fixed shaft. The second reducer 29 is fixedly mounted on the upper end of the fixed plate 27. The rotational speed of the output end of the first reducer 28 is twice that of the output end of the second reducer 29. In use, when the first motor 30 drives the input end of the first reducer 28 to rotate, the fixed shaft drives the input end of the second reducer 29 to rotate through the eighth bevel gear. The second reducer 29 drives the second transmission roller to rotate, causing the second transmission belt 24 to rotate. Since the rotational speed of the output end of the first reducer 28 is twice that of the output end of the second reducer 29, the second moving trolley 23 drives the counterweight box 25 to move while the first moving trolley 14 moves. The first moving trolley 14 and the second moving trolley 23 move in opposite directions, which helps the top frame 15 maintain balance.

[0033] A protective box 31 is fixedly provided on the upper end of the fixing plate 27, which facilitates the protection of the upper part of the fixing plate 27 during use.

[0034] The anti-sway mechanism includes two rigid chains 34 arranged symmetrically. Each chain 34 is wound around two take-up rollers 35, which are rotatably mounted inside a mounting box 40. The mounting box 40 is fixedly located at the bottom of the first moving trolley 14. One end of each rigid chain 34 is fixedly connected to one end of a counterweight block 32. The other end of each counterweight block 32 is connected to a fixing tube 33, which is fixedly mounted on the upper end of the lifting beam 11. A drive shaft is fixedly mounted on the rotating shaft of each take-up roller 35. A worm gear 37 is fixedly mounted on each drive shaft. A worm 38 meshes with each worm gear 37. Support plates are rotatably mounted on the rotating shafts at both ends of the worm 38. The support plates are fixedly mounted on one side of the mounting box 40. The two worms 38 are symmetrically mounted. The system is configured such that a connecting shaft is fixed between the two worm gears 38, and one end of the rotating shaft of one worm gear 38 is fixedly connected to the output end of the second motor 39. A fixed box is provided on one side of the mounting box 40 corresponding to the position of the worm wheel 37. The second motor 39 is fixedly mounted on one side of the fixed box. In use, when the hook 19 is lifting materials, the output end of the second motor 39 drives the two worm gears 38 to rotate. The worm gears 38 mesh with the worm wheel 37, driving the winding roller 35 to rotate. The two top frames 15 rotate in opposite directions, causing the rigid chain 34 to unfold. The fixed tube 33 descends under the action of gravity, while the winch component 13 winds up the steel cable 12. The steel cable 12 drives the lifting beam 11 to rise, so that the counterweight block 32 is inserted and engaged with the fixed tube 33. Under the action of the rigid chain 34, the lifting beam 11 can be prevented from swaying too much.

[0035] Both the bottom of the mounting box 40 and the end of the rigid chain 34 are equipped with sprockets 36, which mesh with the rigid chain 34, making it easy to limit the rigid chain 34 during use.

[0036] Example 2

[0037] The difference from Embodiment 1 is that: the lifting beam 11 is symmetrically provided with adjusting rods 20 inside, and the upper end of each adjusting rod 20 is provided with several adjusting holes. The lifting beam 11 is symmetrically provided with hooks 19 inside, and one end of each hook 19 is fixedly provided with a plug-in bracket 21, which facilitates quick adjustment of the working position of the hook 19 during use.

[0038] The above embodiment discloses a hoisting auxiliary device for offshore wind power construction. When the first moving trolley 14 needs to move on the top of the top frame 15, the first motor 30 is started. The output end of the first motor 30 drives the fixed shaft to rotate, the fixed shaft drives the input end of the first reducer 28 to rotate, and the output end of the first reducer 28 drives the first transmission roller to rotate. The two first transmission rollers cooperate to drive the first transmission belt 22 to rotate. Since the first transmission belt 22 is fixedly connected to the first moving trolley 14, the first transmission belt 22 drives the first moving trolley 14 to move on the top of the top frame 15. At the same time, the fixed shaft drives the input end of the second reducer 29 to rotate through the eighth bevel gear. The second reducer 29 drives the second transmission roller to rotate, causing the second transmission belt 24 to rotate. Since the rotation speed of the output end of the first reducer 28 is twice the rotation speed of the output end of the second reducer 29, the second moving trolley 23 drives the counterweight box 25 to move while the first moving trolley 14 is moving. The first moving trolley 14 and the second moving trolley 23 move in opposite directions, which makes it easier for the top frame 15 to maintain balance.

[0039] When the hook 19 is lifting materials, the output end of the second motor 39 drives the two worm gears 38 to rotate. The worm gears 38 mesh with the worm wheel 37 to drive the winding roller 35 to rotate. The two top frames 15 rotate in opposite directions, which causes the rigid chain 34 to unfold. The fixed tube 33 descends under the action of gravity. At the same time, the hoisting component 13 winds up the steel cable 12. The steel cable 12 drives the lifting beam 11 to rise, so that the counterweight block 32 is inserted and engaged with the fixed tube 33. Under the action of the rigid chain 34, the lifting beam 11 can be prevented from swaying too much.

[0040] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
