Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine components, and in particular to a wind turbine nacelle roof inclined support bracket. Background Technology

[0002] The nacelle roof support is an important structural component on the top of the nacelle of a wind turbine generator. It comes in various specifications, and a support is needed to lift the roof when overhauling the nacelle roof.

[0003] Over long-term use, the surface structure of the wind turbine's roof can be damaged by environmental factors. Workers need to climb to the damaged areas, grind away the broken parts, and then apply new material for curing. This operation is difficult and extremely dangerous for the workers. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides a structurally sound inclined support bracket for the top of the wind turbine nacelle, which can provide reliable support while reducing the area that needs to be climbed for maintenance and improving operational safety.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A wind turbine nacelle roof bracing bracket, used between the upper roof and the lower nacelle, includes a scissor lift platform and a swing arm for supporting the upper roof.

[0007] The bottom of the scissor lift platform rests within the lower compartment, which is equipped with a slide rail. The scissor lift platform drives the upper cover to reciprocate along the slide rail.

[0008] The swing arm and the scissor lift are located at opposite corners of the upper cover. The bottom end of the swing arm is hinged to the lower cabin, and the top end of the swing arm moves in an arc along the inner wall of the upper cover as the upper cover moves.

[0009] As a further improvement to the above technical solution:

[0010] The top of the scissor lift platform is fixedly connected to the inner wall of the upper cover.

[0011] The bottom of the scissor lift rests on the slide rail, and the initial position of the scissor lift has a movement margin between it and both ends of the slide rail.

[0012] The top of the swing arm is designed to swing back and forth along the length of the slide rail.

[0013] The inner wall of the upper cover is provided with a sliding groove, which is parallel to the slide rail, and the top of the swing rod swings back and forth in the sliding groove.

[0014] The chute has an arc bottom, and the chute depth in the middle section is greater than the chute depth at both ends.

[0015] In the initial state, the swing arm is located in the middle of the slide.

[0016] When the top cover is pushed to its limit position, the top of the lever contacts one of the top positions of the slide.

[0017] The swing arm is a telescopic rod.

[0018] The scissor lift and swing arm form the support assembly, and the wind turbine nacelle is equipped with at least one set of support assemblies.

[0019] The beneficial effects of this utility model are as follows:

[0020] This utility model utilizes a combined support structure of scissor lift platform and diagonal brace, which can provide lifting and support force to the upper cover. At the same time, it also utilizes the sliding structure inside the cabin and the upper cover to move the upper cover to an eccentric position relative to the lower cabin. This allows operators to perform maintenance on parts of the upper cover surface without having to climb and hang, and can do so from inside the lower cabin, greatly improving safety.

[0028] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0029] like Figures 1-6 As shown, the wind turbine nacelle roof inclined support bracket of this embodiment is applied between the upper roof 1 and the lower nacelle 2, and includes a scissor lift platform 3 and a swing arm 4 for supporting the upper roof 1.

[0030] The bottom of the scissor lift platform 3 rests inside the lower compartment 2, and the lower compartment 2 is equipped with a slide rail 5. The scissor lift platform 3 drives the upper cover 1 to reciprocate along the slide rail 5.

[0031] The swing arm 4 and the scissor lift 3 are located at opposite corners of the upper cover 1. The bottom end of the swing arm 4 is hinged to the lower cabin 2, and the top end of the swing arm 4 moves in an arc along the inner wall of the upper cover 1 as the upper cover 1 is displaced.

[0032] The top of the scissor lift platform 3 is fixedly connected to the inner wall of the upper cover 1.

[0033] The bottom of the scissor lift 3 rests on the slide rail 5. The initial position of the scissor lift 3 and both ends of the slide rail 5 are reserved for movement.

[0034] The top of the lever 4 is set to swing back and forth along the length of the slide rail 5.

[0035] The inner wall of the upper cover 1 is provided with a sliding groove 6, which is parallel to the slide rail 5. The top of the swing rod 4 swings back and forth in the sliding groove 6.

[0036] The groove 6 is an arc-bottomed groove, and the groove depth in the middle section of the groove 6 is greater than the groove depth at both ends of the groove 6.

[0037] In the initial state, the swing arm 4 is located in the middle section of the slide 6.

[0038] When the top cover 1 is pushed to its limit position, the top of the lever 4 abuts against one of the top positions of the slide 6.

[0039] The swing arm 4 is a telescopic rod.

[0040] The scissor lift platform 3 and the swing arm 4 form a support assembly, and the wind turbine nacelle is equipped with at least one set of support assemblies.

[0041] The specific structure and working principle of this utility model are as follows:

[0042] like Figure 1 The diagram shown is a schematic of a wind turbine nacelle of one specification, illustrating the completed assembly of the upper roof 1 and the lower nacelle 2. Figure 2 As shown, the lower hull 2 ​​is hidden, revealing the support components used to support the upper dome 1.

[0043] The support components have two structures. Taking one set of support components as an example, combined with... Figure 3 Figure 4 Please provide an explanation.

[0044] In a set of support components, scissor lifts 3 and telescopic rods are respectively installed at the two opposite corners of the upper cover 1 of the rectangle.

[0045] The top of the scissor lift platform 3 is fixedly connected to the upper cover 1, and the bottom of the scissor lift platform 3 can slide back and forth on the slide rail 5 at the bottom of the lower cabin 2.

[0046] The telescopic mast uses commercially available components and provides axial support after extension. An arc-shaped groove 6 is provided on the inner wall of the upper cover 1, and the top of the telescopic mast extends into the groove 6. A ball joint that will not fall out and is embedded in the groove 6 can be provided at the top of the telescopic mast to reduce frictional resistance and ensure that the telescopic mast is pulled up during jacking. The bottom of the telescopic mast is hinged to the lower hull.

[0047] from Figure 1 Status Figure 2 In the current state, the scissor lift platform 3 first lifts the object, and simultaneously, the telescopic rod that is engaged with the slide groove 6 at the top is stretched; then, a power source such as a cylinder drives the scissor lift platform 3 to slide along the slide rail 5. At this time, as... Figure 5 and Figure 6 As shown, the bottom of the swing arm 4 is hinged and remains stationary, while the top moves within the slide groove 6 as the upper cover 1 shifts, until it contacts one end of the slide groove 6. At this point, the telescopic force on the telescopic rod is not vertically downward, so theoretically, it will not exert a force that causes the telescopic rod to retract. At this time, the upper cover 1 is supported by the scissor lift 3 and the swing arm 4. Moreover, since the upper cover 1 has shifted, there is a displacement difference between it and the lower compartment 2. Workers can use this displacement difference to stand in the lower compartment 2 and repair a certain side wall. When the scissor lift 3 moves in the opposite direction, the opposite side wall can be repaired.

[0048] As an alternative implementation, a set of support components can all be made using a scissor lift platform 3.

[0049] As an alternative implementation, two sets of support components can be used and applied to the same cabin.

[0050] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
