Description

Technical Field

[0001] The utility model belongs to the technical field of offshore maintenance equipment, and in particular relates to a buffer landing ladder for offshore wind power maintenance. Background Art

[0002] The buffer landing ladder for offshore wind power maintenance is a device designed specifically for offshore wind farms to allow operation and maintenance personnel to safely and conveniently board offshore wind turbines.

[0003] The prior art discloses an offshore wind power maintenance buffer boarding device (CN207725578U), comprising a base installed on the bow deck and a landing ladder fixed at the bottom end to the base, wherein the landing ladder is folded or straightened by each ladder beam hinged in sequence from head to tail, and the two connected ladder beams are provided with corresponding locking devices and snap devices at the connecting ends; the bow of the utility model does not need to be close to the mooring pile at the bottom of the wind turbine, which avoids the bow of the operation and maintenance ship colliding with the mooring pile due to environmental factors in relatively severe sea conditions and causing damage to the bow of the ship; when in use, the landing ladder is locked by the matching locking device and snap device to ensure the stability of the landing ladder; at the same time, the direction facing the mooring pile can be changed at any time by the gear on the fixed base and the hinge device on the gear, and the front and rear position of the base can also be changed by the bottom slide rail, which has good flexibility and makes the operation and maintenance ship no longer need to open the bow to the specified direction facing the mooring pile, saving time and effort, and the bow only needs to be close to the top mooring pile.

[0004] After searching, it was found that the device uses multiple ladder beams for connection. When in use, the length of the landing ladder itself cannot be adjusted and controlled according to the actual environment needs, which leads to limitations in the applicable environment of the device and is not conducive to the large-scale use of the device. Moreover, when responding to emergencies, the device cannot adjust the distance between the ladder beams, which limits the number of people using the device and is not convenient for responding to emergencies, resulting in the device being less practical.

[0030] The working principle is as follows: the fixed plate 10 is fixed to the deck by bolts, and by setting a pushing structure, the screw rod 17 is used to drive the movement of the telescopic block 16, thereby pushing the deformation of the shear frame 11, and then the ladder beam 21 is pushed. The ladder beam 21 moves on the limit rod 19 to achieve the purpose of adjusting the length of the device, so that the device can be applied to different environments, thereby expanding the scope of use. By setting a telescopic structure, the brackets 12 on both sides are pushed to cause the telescopic ladder 25 to open, and at the same time, the brackets 12 on both sides are slid to both ends on the fixed plate 10, so that the distance between the ladder beams 21 on both sides can be expanded, helping more people to use the device to cope with emergencies, thereby enhancing the practicality of the device.

[0031] like Figure 1 and Figure 3 As shown, the fixed plate 10 is an L-shaped structure, a slide groove 13 is provided on one side of the fixed plate 10, two brackets 12 are symmetrically provided, and the two brackets 12 are fixedly connected to the side close to the fixed plate 10 with a slider 14, and the slider 14 slides in the slide groove 13; Figure 2 As shown, a waterproof motor 15 is fixed to the inner bottom surface of one of the brackets 12 through a triangular bracket, and a rotation groove is opened on the inner top surface of one of the brackets 12. A screw rod 17 is connected to the rotating groove through a bearing.

There are multiple ladder beams 21 symmetrically arranged, and a telescopic ladder 25 is fixedly arranged between the ladder beams 21 on both sides.

[0032] The working principle is as follows: first, according to the number of users, the brackets 12 on both sides are pushed open, and the brackets 12 on both sides drive the respective connected pushing structures to move to both sides. In this process, the brackets 12 on both sides slide in the slide groove 13 with the help of the slider 14, and the telescopic ladder 25 supports the ladder beams 21 on both sides. At this time, the waterproof motor 15 is started, and the screw rod 17 rotates. The screw rod 17 rotates to move the telescopic block 16 with a threaded hole. At the same time, the shear frame 11 connected to the screw rod 17 side is driven, pushing the ladder beam 21 to slide on the limit rod 19. The limit rod 19 is provided with a circular plate with a diameter greater than 24 at one end away from the bracket 12. The limit rod 19 limits the movement of the ladder beam 21 through the circular plate. Synchronously, the shear frame 11 on the screw rod 17 side drives the ladder beam 21 to move, which in turn drives the telescopic step 25 to move. At this time, the pushing structure on the other side will move together with the pushing structure on the screw rod 17 side. At this time, in order to cooperate with the movement of the pushing structures on both sides, the telescopic block 16 with a sliding hole will slide synchronously on the sliding rod 18, thereby cooperating with the simultaneous movement of the two pushing structures.

[0033] like Figure 1 、 Figure 2 and Figure 5 As shown, a pillar 20 is fixedly provided on the inner wall surface of each of the two brackets 12, and a cylinder is fixedly connected to each side of the two telescopic blocks 16 close to the bracket 12. The shear frame 11 includes a connecting rod itself, a fixed end 26, a movable end 27, a movable end 28 and a telescopic end 29. The fixed end 26, the movable end 27, the movable end 28 and the telescopic end 29 are all circular holes. The fixed end 26 is rotatably connected to the pillar 20 through a corresponding bearing, and the telescopic end 29 is rotatably connected to the cylinder through a corresponding bearing; Figure 4 and Figure 5As shown, one side of the ladder beam 21 is fixedly connected to a short column, and a slide 23 is provided inside the ladder beam 21. The slide 23 is located directly below the short column, and a moving block 22 is slidably connected inside the slide 23. One side of the moving block 22 is fixedly connected to a shaft column, and the moving end 27 is rotatably connected to the short column through an internal bearing, and the movable end 28 is rotatably connected to the shaft column through an internal bearing.

[0034] The specific implementation is as follows. Before use, first, according to the number of users, choose whether to push the brackets 12 on both sides apart. If the brackets 12 on both sides are pushed apart, the respective connected pushing structures will be driven to move to both sides. At the same time, during this process, the telescopic ladder 25 between the two brackets 12 will support the ladder beams 21 on both sides. When in use, start the waterproof motor 15, the waterproof motor 15 drives the screw rod 17 to rotate, and the screw rod 17 rotates to move the telescopic block 16 with a threaded hole. At the same time, the telescopic end 29 of the shear frame 11 connected to the screw rod 17 side moves toward the fixed end 26 under the guidance of the telescopic block 16, and the movable end 28 pushes the moving block 22 to move in the slide 23. At this time, the shear frame 11 is deformed, and the moving end 27 and the movable end 28 are able to push the ladder beam 21 to slide on the limit rod 19. At this time, the ladder beam 21 drives the telescopic ladder 25 to move. Here, the surface of the telescopic ladder 25 is provided with anti-slip grooves to avoid the influence of the shape of the telescopic ladder 25 on the user's physical feel and safety. At the same time, the pushing structure on the slide rod 18 side is not active, and the pushing structure on the slide rod 18 side moves with the movement of the screw rod 17 side. Finally, the waterproof motor 15 is externally connected to a waterproof switch, and the switch controls the forward and reverse rotation of the waterproof motor 15. The forward switch controls the waterproof motor 15 to push the pushing structure, and the reverse switch controls the waterproof motor 15 to recover the pushing structure. The use of the water release switch can help the device better adjust the landing length.
