Description

Technical Field

[0001] This utility model relates to the field of guide rail technology, specifically a wedge-shaped interlocking guide rail for offshore wind turbine tower climbing ladders. Background Technology

[0002] The wedge-shaped interlocking guide rail for offshore wind turbine tower climbing ladders is installed between two outer frames via an installation assembly for use with a climbing-free device. For details, please refer to the climbing-free device vehicle body and wind turbine tower climbing-free device described in announcement number CN220033945U, which includes a frame assembly comprising a vehicle frame, handles, an operating platform, and wheels. The operating platform is located on the top of the vehicle frame, the handles are located on both sides of the vehicle frame, and the wheels are located on the back of the vehicle frame. It also includes a load-bearing assembly comprising a pedal, a first spring, and a fixing member, the pedal being rotatably connected to the bottom front of the vehicle frame.

[0003] The above-mentioned device is based on existing guide rails and ladder rods. However, the existing guide rails and ladder rods are integrated after being fixed. In the later stage, disassembling individual ladder rods requires disassembling multiple threaded fixing components, or cutting the ladder rods separately, which makes the later maintenance of the ladder rods inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a wedge-shaped interlocking guide rail for offshore wind turbine tower climbing ladders to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wedge-shaped interlocking guide rail for an offshore wind turbine tower ladder includes a slide rail body installed between two outer frames. The bottom of the slide rail body is wedge-shaped, and a stop block is fixedly connected to the upper surface of the wedge-shaped body.

[0007] The outer surface of the slide rail body is fitted with a ladder rod. The ladder rod has two movably connected snap-fit ​​structures inside. Each snap-fit ​​structure includes a first wedge, a second wedge, and a connecting rod. The first wedge is slidably connected to the inside of the ladder rod, and a first slide rail is fixedly connected to the upper surface of the first wedge. The second wedge is slidably connected to the inside of the ladder rod, and a second slide rail is fixedly connected to the upper surface of the second wedge. The connecting rod is slidably connected to the inside of the first and second slide rails, and a U-shaped connecting frame is fixedly connected to the upper surface of the connecting rod.

[0008] Furthermore, the outer frame has connecting plates embedded at both ends, and inserts are fixedly connected to both sides of the connecting plates. The outer surface of the connecting plates has slots, and the slide rail body passes through the slots.

[0009] Furthermore, the outer surface of the slide rail body is engaged with a pressing block, the pressing block and the stop block are in close contact, and the pressing block and the second wedge block are fixedly connected.

[0010] Furthermore, the insert block and the outer frame are inserted together, and a connecting stud is embedded in the outer surface of the outer frame, with nuts threaded to both ends of the connecting stud.

[0011] Furthermore, an anti-slip pad is fixedly connected to the side surface of the ladder rod, and an anti-slip groove is formed on the outer surface of the anti-slip pad.

[0012] Furthermore, the outer surface of the outer frame is provided with an insertion hole, and the first wedge is inserted into the insertion hole.

[0013] Furthermore, the upper surface of the ladder rod is fixedly connected to a fixing frame via a threaded assembly. The inner surface of the fixing frame is provided with a snap-fit ​​groove. A snap-fit ​​plate is slidably connected inside the snap-fit ​​groove. A bolt is threadedly connected to the upper surface of the snap-fit ​​plate. A circular baffle is fixedly connected to the lower end of the bolt. The circular baffle and the connecting frame are slidably connected.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By rotating the bolt, the circular baffle applies an upward force to the connecting frame under the push of the thread, which can precisely control the up and down movement of the snap-fit ​​plate, thereby driving the connecting rod to rise. When moving, it works with the first and second slide rails to apply force to the first and second wedge blocks, further causing the first and second wedge blocks to retract, thus separating the first wedge block from the outer frame and causing the second wedge block to lose its limit on the slide rail body, so that the individual ladder rod can be removed, which is convenient for individual inspection or replacement of the ladder rod;

[0016] 2. The embedded connection between the outer frame and the connecting plate, and the connection between the connecting plate and the outer frame through the plug-in cooperation of the plug, realize the tight connection between the outer frame and the connecting plate, which makes it easy to connect multiple outer frames together and adapt to offshore wind turbine towers of different heights.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 In this embodiment of the utility model, a wedge-shaped interlocking guide rail for a climbing ladder of an offshore wind turbine includes a slide rail body 3 installed between two outer frames 1. The bottom of the slide rail body 3 is a wedge-shaped body 301, and a stop block 302 is fixedly connected to the upper surface of the wedge-shaped body 301.

[0024] The outer surface of the slide rail body 3 is snapped with a ladder rod 4. The interior of the ladder rod 4 is movably connected with two snap-fit ​​structures 5. The snap-fit ​​structure 5 includes a first wedge 501, a second wedge 503, and a connecting rod 506. The first wedge 501 is slidably connected to the interior of the ladder rod 4. The upper surface of the first wedge 501 is fixedly connected to a first slide rail 502. The second wedge 503 is slidably connected to the interior of the ladder rod 4. The upper surface of the second wedge 503 is fixedly connected to a second slide rail 504. The connecting rod 506 is slidably connected to the interior of the first slide rail 502 and the second slide rail 504. The upper surface of the connecting rod 506 is fixedly connected to a connecting frame 507 with a U-shaped cross section.

[0025] Specifically, during use, the slide rail body 3 is connected to the two outer frames 1 via the ladder rod 4. The outer frames 1 are installed inside the offshore wind turbine tower via threaded assemblies. When a single ladder rod 4 needs to be disassembled, the connecting rod 506 is moved upward. During the movement, it works in conjunction with the first slide rail 502 and the second slide rail 504 to apply force to the first wedge block 501 and the second wedge block 503, further causing the first wedge block 501 and the second wedge block 503 to retract. This allows the first wedge block 501 to separate from the outer frame 1, and the second wedge block 503 to lose its restraint on the slide rail body 3. This allows the single ladder rod 4 to be removed, facilitating individual inspection or replacement of the ladder rod 4.

[0026] Example 1

[0027] like Figure 1-4 As shown, connecting plates 2 are embedded at both ends of the outer frame 1. Insert blocks 201 are fixedly connected to both sides of the connecting plate 2. A slot 202 is opened on the outer surface of the connecting plate 2. The slide rail body 3 passes through the slot 202. The insert blocks 201 and the outer frame 1 are inserted into each other. A connecting stud 101 is embedded on the outer surface of the outer frame 1. Nuts are threaded at both ends of the connecting stud 101.

[0028] In this embodiment, the embedded connection between the outer frame 1 and the connecting plate 2, and the connection between the connecting plate 2 and the outer frame 1 through the insertion block 201, achieve a tight connection between the outer frame 1 and the connecting plate 2, which facilitates the connection of multiple outer frames 1 together and makes it easy to adapt to offshore wind turbine towers of different heights.

[0029] like Figure 1-4 As shown, an anti-slip pad 401 is fixedly connected to the side surface of the ladder rod 4, and an anti-slip groove is provided on the outer surface of the anti-slip pad 401.

[0030] In this embodiment, the anti-slip mat 401 is fixedly connected to the side surface of the ladder rod 4. The anti-slip groove can effectively increase the friction coefficient of the ladder rod 4 surface, prevent workers from slipping when climbing the ladder, and improve the safety of climbing the ladder. The anti-slip mat 401 is made of wear-resistant material and can withstand long-term friction and harsh marine environment, ensuring the durability of its anti-slip performance.

[0031] Example 2

[0032] Based on Embodiment 1, in order to overcome the problem that it is inconvenient to lift the connecting rod 506 in Embodiment 1.

[0033] like Figure 1-4 As shown, a fixing frame 6 is fixedly connected to the upper surface of the ladder rod 4 by a threaded assembly. A snap-fit ​​groove 601 is provided on the inner surface of the fixing frame 6. A snap-fit ​​plate 602 is slidably connected inside the snap-fit ​​groove 601. A bolt 603 is threadedly connected to the upper surface of the snap-fit ​​plate 602. A circular baffle is fixedly connected to the lower end of the bolt 603. The circular baffle and the connecting frame 507 are slidably connected.

[0034] In this embodiment, the upper surface of the ladder rod 4 is fixedly connected to the fixing frame 6 by a threaded assembly, and the locking groove 601 and locking plate 602 inside the fixing frame 6 provide a convenient way to lift the connecting rod 506. By rotating the bolt 603, the circular baffle applies an upward force to the connecting frame 507 under the push of the thread, which can precisely control the up and down movement of the locking plate 602, thereby driving the lifting of the connecting rod 506.

[0035] like Figure 1-4As shown, a pressing block 505 is engaged with the outer surface of the slide rail body 3. The pressing block 505 and the stop block 302 are in close contact. The pressing block 505 and the second wedge block 503 are fixedly connected. An insertion hole 102 is opened on the outer surface of the outer frame 1. The first wedge block 501 is inserted into the interior of the insertion hole 102.

[0036] In this embodiment, the pressing block 505, which is engaged with the outer surface of the slide rail body 3, is in close contact with the stop block 302 and is fixedly connected to the second wedge block 503. After the second wedge block 503 retracts, the slide rail body 3 can lose the limiting position of the pressing block 505, which can effectively prevent the slide rail body 3 from shifting or loosening during use. At the same time, the first wedge block 501 is inserted into the insertion hole 102 on the outer surface of the outer frame 1, which further enhances the connection stability between the ladder rod 4 and the outer frame 1.

[0037] 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.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
