Description

Technical Field

[0001] This utility model relates to the technical field of fixing maintenance ladders for wind turbine towers, and in particular to a fixing device for maintenance ladders for offshore wind turbine towers that is easy to disassemble and assemble. Background Technology

[0002] Currently, mobile maintenance ladders are installed on offshore wind turbine tower platforms for maintaining mechanical parts at different heights. Since wind turbine towers exceed 100 meters in height, especially at sea, their swaying is significant. When not in use, the maintenance ladders need to be secured to prevent them from sliding and causing collisions with machinery or personnel. Existing fixed maintenance ladder structures are directly bolted to the platform. While this structure is relatively robust, it requires tools to remove the bolts each time it is used, and to align and tighten them again when putting it back, making it inconvenient and time-consuming. Another method uses chains wrapped around fixed points, avoiding bolt removal. However, because the chains cannot be fully tightened, they only limit the ladder's sliding; in strong winds and significant swaying, sliding and collisions can still occur. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an easily detachable and assembleable fixing device for offshore wind turbine tower maintenance ladders. This device ensures complete fixation of the maintenance ladder, preventing collisions due to tower swaying. During use, the maintenance ladder can be quickly and easily removed; after use, it can be conveniently replaced and secured.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: an easily detachable and assembleable offshore wind turbine tower maintenance ladder fixing device, comprising a fixing base, a fixing baffle, bolts, a hinged bolt, a wing nut, a clamping plate, and a clamp; the fixing base is installed on the wall of the offshore wind turbine tower, the fixing baffle is installed on the fixing base and the fixing baffle is provided with two ear plates, the hinged bolt is disposed between the two ear plates, the bolt passes vertically through the bolt holes of the two ear plates and the hinged bolt to form a detachable connection, and the hinged bolt and the bolt form a rotatable connection; the clamping plate and the clamp are respectively clamped on both sides of the maintenance ladder and connected, the clamping plate is provided with a slot, the free end of the hinged bolt passes through the slot and is fitted with a wing nut.

[0005] Furthermore, the fixing seat is provided with symmetrical waist-shaped holes.

[0006] Furthermore, the fixed baffle includes an L-shaped plate and a base plate; one end of the L-shaped plate is connected to the base plate, the base plate is provided with symmetrical bolt holes and the bolt holes correspond one-to-one with the waist-shaped holes of the fixed seat; the two ear plates are arranged on one side of the L-shaped plate and the two ear plates are arranged at opposite ends, each ear plate is provided with bolt holes and the bolt holes of the two ear plates correspond to each other.

[0007] Furthermore, the card slot is located at one end of the card plate; the middle part and the other end of the card plate are provided with waist-shaped holes.

[0008] Furthermore, the clamp has bolt holes at both ends, and the bolt holes of the clamp correspond one-to-one with the waist-shaped holes of the clamp plate.

[0009] Furthermore, the bolt is an M8×50 bolt.

[0010] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0011] This utility model uses a movable hinge bolt passing through the slot and a wing nut to press the clamping plate and the fixed baffle to fix the maintenance ladder. The maintenance ladder only needs to be moved to a position that is roughly in contact with the baffle. The wing nut can be tightened and loosened without tools, which greatly improves the convenience of use and shortens the time for putting back and taking out the maintenance ladder.
