[0002] Offshore wind power generation is a technology that uses offshore wind energy to generate electricity. Offshore wind turbines require the use of corresponding wind turbine units to convert wind energy into mechanical energy, and then into electrical energy through generators. If the wind turbine units and generators are damaged during use, they need to be repaired. During repair, component lifting equipment is needed to lift and move the components to be repaired.
[0003] Traditional lifting devices for offshore wind power maintenance and construction are impractical because they make it difficult to move the lifted components back and forth. Therefore, we propose an improved lifting device for offshore wind power maintenance and construction to address these issues. Utility Model Content

[0011] Preferably, a connecting seat is fixed on the left side of the connecting block, and a telescopic cylinder is installed inside the connecting seat. A locking rod is installed at the bottom end of the telescopic cylinder, and a locking seat is installed at the top left side of the hook.
[0012] Preferably, the cross-section of the locking rod is smaller than the cross-section of the locking seat, and the locking rod and the locking seat form an engaging structure.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the lifting device for offshore wind power maintenance and construction components not only allows for adjustment of the front and rear positions of the hook according to actual needs, thus protecting the hook and preventing items from falling during the lifting process, but also greatly increases the structural strength of the main body of the lifting device.
[0014] (1) When the lifting device lifts the power maintenance component, it is equipped with components such as a second servo motor, threaded rod, moving seat and slider. This enables the device to not only lift the power component from one direction to another, but also to move the power component back and forth and move it laterally according to actual needs, thus making the lifting device more practical.
[0015] (2) By providing components such as telescopic cylinder, connecting seat, clamp rod and clamp seat, when the lifting device is in use, after the rope of the object to be lifted is installed inside the hook, the telescopic cylinder in the above components can push the clamp rod to engage inside the clamp seat, thereby closing the opening on one side of the hook, thus preventing the rope lifted inside the hook from coming out of the hook, and making the lifting device more stable in lifting goods.
[0016] (3) By setting up reinforcing rods and ribs, the crane frame is the main body of the lifting device for rotation operation. After the reinforcing rods and ribs are set at the bottom of the base, the base can be supported and reinforced, which greatly increases the structural strength of the base. It is not easy to deform and be damaged as the usage time increases, thereby improving the service life of the lifting device. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 This utility model provides an embodiment: a lifting device for components used in offshore wind power maintenance and construction, including a base 1, a crane frame 3 installed on the right side of the top of the base 1, a first servo motor 2 installed on the left side of the top of the base 1, a steel cable 10 provided at one end of the first servo motor 2, and a connecting block 13 fixed to the right side of the crane frame 3 at one end of the steel cable 10, a hook 14 installed at the bottom end of the connecting block 13, a guide wheel 4 fixed on the left side of the base 1, a movable seat 8 installed at the top right side of the crane frame 3, a threaded rod 6 movably provided at the rear end of the movable seat 8, and a second servo motor 7 installed on the left side of the threaded rod 6. A movable block 17 is movably mounted on the side wall, and a fixed plate 18 is installed at the front end of the movable block 17. A conveyor wheel 5 is movably mounted inside the fixed plate 18 via a rotating shaft 9. A slider 15 is fixed at the front end of the conveyor wheel 5. A groove 16 is provided on the outer side wall of the slider 15, and the groove 16 is located at the front end inside the movable seat 8. The cross-section of the slider 15 is smaller than the cross-section of the groove 16, and a sliding structure is formed between the slider 15 and the groove 16. The inner side wall of the movable block 17 is uniformly provided with internal threads, and a threaded connection is formed between the movable block 17 and the threaded rod 6. The design of the sliding structure and the threaded connection enable the fixed plate 18 to drive the conveyor wheel 5 to move stably.
[0024] Specifically, such as Figure 1 and Figure 2As shown, when lifting goods, the second servo motor 7 can be started to drive the threaded rod 6 to rotate. The rotation of the threaded rod 6 will drive the moving seat 8 from one side to the other side through the moving block 17, thereby moving the goods lifted by the bottom hook 14 from one side to the other side, and performing a certain distance of lifting and moving.
[0025] A connecting seat 20 is fixed on the left side of the connecting block 13, and a telescopic cylinder 19 is installed inside the connecting seat 20. A locking rod 21 is installed at the bottom end of the telescopic cylinder 19, and a locking seat 22 is installed at the top left side of the hook 14. The cross-section of the locking rod 21 is smaller than the cross-section of the locking seat 22. The locking rod 21 and the locking seat 22 form a locking structure, which makes the closure of the opening of the hook 14 more stable.
[0026] Specifically, such as Figure 1 and Figure 3 As shown, the rope of the cargo is placed inside the hook 14. The telescopic cylinder 19 is activated to push the locking rod 21 to engage inside the locking seat 22 on the left side of the guide wheel 4, closing the hook 14 to ensure the stability of the rope inside the hook 14. Then, the telescopic cylinder 19 is activated again to pull the locking rod 21 out from inside the locking seat 22, which opens the protection of the hook 14 and allows the rope inside to be removed, thereby taking down the hoisted cargo.
[0027] A reinforcing rod 11 is installed on the left side of the crane frame 3, and the bottom end of the reinforcing rod 11 is fixed to the top end of the base 1. A reinforcing rib 12 is welded and fixed inside the reinforcing rod 11. Several reinforcing ribs 12 are provided, and the several reinforcing ribs 12 are distributed at equal intervals inside the reinforcing rod 11. There are four sets of reinforcing rods 11. The four sets of reinforcing rods 11 are symmetrically distributed about the central axis of the crane frame 3, which has a better reinforcement effect on the crane frame 3 and makes the structure of the crane frame 30 more stable.
[0028] Specifically, such as Figure 1 As shown, the reinforcing rod 11 and the reinforcing rib 12 are welded together to form an integral support at the bottom of the crane frame 3, which greatly increases the structural strength of the crane frame 3.
[0029] Working Principle: In use, the lifting device is installed on a corresponding rotating mechanism. When in use, the first servo motor 2 is activated, causing the hook 14 pulled by the steel cable 10 to descend to the bottom. Then, the rope used to pack the goods is placed inside the hook 14. The telescopic cylinder 19 is activated, pushing the locking rod 21 to engage with the locking seat 22 on the left side of the guide wheel 4, closing the hook 14. After closing, the first servo motor 2 is activated, pulling the steel cable 10 upwards, thus moving the lifted goods upwards. Next, the rotating mechanism is activated, lifting the goods to the desired direction. The second servo motor 7 can be activated to rotate the threaded rod 6. The rotation of the threaded rod 6, through the moving block 17, moves the moving seat 8 from one side to the other, allowing the lifted goods to move a certain distance to the appropriate position. After moving to the appropriate position, the goods are lowered, and the telescopic cylinder 19 is activated, pulling the locking rod 21 out of the locking seat 22 to open the protection of the hook 14.
[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
