Abstract

This invention provides a wind turbine blade fish skeleton placement bracket, which includes a placement frame, a support frame, and a support assembly. In use, the placement frame and support frame can be installed on the ground, and their positions adjusted according to the length of the fish skeleton. Then, a forklift or crane is used to lift the finished fish skeleton onto the two placement frames, with the two ends of the main shaft of the fish skeleton overlapping the two placement frames. Finally, the height of the support assembly on the support frame is adjusted so that it supports the middle of the main shaft of the fish skeleton, effectively supporting the main shaft. This prevents deformation of the fish skeleton due to long-term placement, which would affect the overall shape of the blade.

Description

Technical Field

[0001] This utility model belongs to the field of wind power generation technology, specifically relating to a fish skeleton support for wind turbine blades. Background Technology

[0002] Small wind turbine blades consist of an internal fish-like frame and an outer shell surrounding it. The fish-like frame primarily supports and shapes the blades, ensuring a stable form and thus guaranteeing the stability of the wind turbine's operation.

[0003] During the production process, a fish skeleton needs to be manufactured, and then the outer shell is installed onto the fish skeleton. The finished fish skeleton is first placed on a storage rack for storage and organization. Currently, the conventional way to store fish skeletons is to attach both ends of the fish skeleton to two support frames. However, with this method, the middle of the fish skeleton is mostly suspended in the air. Over time, the fish skeleton is prone to deformation and is not easy to correct, which affects the shape of the fan blades later. Utility Model Content

[0004] This utility model provides a support for placing the fish skeleton of wind turbine blades, which aims to solve the problem that the fish skeleton of wind turbine blades is prone to deformation during storage, affecting the later blade shape.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a support bracket for placing the fish skeleton of a wind turbine blade, comprising: There are two placement racks, and the two ends of the fish skeleton are respectively attached to the two placement racks; A support frame is installed between the two placement frames; A support assembly, mounted on the support frame, is used to support the middle part of the fish skeleton. The position of the support assembly on the support frame has a degree of freedom that can be adjusted in the vertical direction.

[0006] In one possible implementation, the support component includes: The mounting base is installed on the support frame and has a degree of freedom to adjust its position on the support frame in the vertical direction; There are two support rollers, which are arranged parallel to each other and rotatably mounted on the mounting base. The axis of the support rollers is arranged along the interval direction of the two placement frames.

[0007] In one possible implementation, the support frame is further equipped with a base for mounting the mounting seat, the base having a degree of freedom to be adjusted along the length of the support frame.

[0008] In one possible implementation, at least two guide posts are fixedly installed on the side wall of the mounting base, and the base is provided with guide holes for guiding the guide posts to move up and down.

[0009] In one possible implementation, the support frame is threaded with a fastener for fixing the base to the support frame, and the base is provided with an elongated hole for mounting the fastener.

[0010] In one possible implementation, a wedge block is slidably disposed on the base, the wedge block being supported at the bottom of the mounting base, and the base is further provided with a pusher for moving the wedge block.

[0011] In one possible implementation, the pusher is threaded onto the base, and one end of the pusher is provided with an abutment for abutting against the outer wall of the wedge block.

[0012] In one possible implementation, two wedge blocks are slidably disposed on the base, and the two wedge blocks are disposed opposite each other along the sliding direction.

[0013] In one possible implementation, a plurality of limiting blocks are fixedly installed on the placement rack, and two adjacent limiting blocks form a placement groove for placing the end of the fish skeleton.

[0014] In one possible implementation, the bottom of the placement rack and the support frame is equipped with a plurality of support legs for adjusting the height.

[0015] The solution shown in this application, compared with the prior art, uses two spaced-apart placement frames with a support frame installed between them. A support component for supporting the middle of the fish skeleton is mounted on the support frame, and the position of the support component on the support frame can be adjusted vertically. In use, the placement frames and support frame can be installed on the ground, and their positions adjusted according to the length of the fish skeleton. Then, a forklift or crane is used to lift the finished fish skeleton above the two placement frames, with both ends of the main shaft of the fish skeleton overlapping the two placement frames. Finally, the height of the support component on the support frame is adjusted so that the support component can support the middle of the main shaft of the fish skeleton, effectively supporting the main shaft. This prevents the fish skeleton from deforming during long-term placement, which would affect the overall shape of the fan blades later. Attached Figure Description

Detailed Implementation To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Please refer to the following: Figures 1 to 3 The present invention provides a description of the wind turbine blade fish skeleton placement bracket. The wind turbine blade fish skeleton placement bracket includes a placement frame 1, a support frame 2, and a support assembly 3. There are two placement frames 1, with both ends of the fish skeleton resting on the two placement frames 1 respectively; the support frame 2 is installed between the two placement frames 1; the support assembly 3 is installed on the support frame 2 and is used to support the middle part of the fish skeleton. The position of the support assembly 3 on the support frame 2 has a degree of freedom for vertical adjustment.

[0019] The wind turbine blade fish skeleton placement bracket provided in this embodiment, compared with the prior art, features two spaced-apart placement frames 1, with a support frame 2 installed between them. A support component 3 for supporting the middle of the fish skeleton is mounted on the support frame 2, and the position of the support component 3 on the support frame 2 can be adjusted vertically. In use, the placement frames 1 and support frame 2 can be installed on the ground, and their positions adjusted according to the length of the fish skeleton. Then, a forklift or crane is used to lift the finished fish skeleton above the two placement frames 1, with both ends of the main shaft of the fish skeleton overlapping the two placement frames 1. Finally, the height of the support component 3 on the support frame 2 is adjusted so that the support component 3 can support the middle of the main shaft of the fish skeleton, effectively supporting the main shaft. This prevents deformation of the fish skeleton due to long-term placement, which would affect the overall shape of the blades later.

[0020] Specifically, in this embodiment, the fish skeleton includes a main shaft and multiple abdominal plates fixedly mounted on the main shaft. Both the placement frame 1 and the support frame 2 are freely mounted on the ground. The placement frame 1 has multiple placement positions for placing the main shaft of the fish skeleton, and the support frame 2 is equipped with a set of support components 3 for supporting the middle sections of multiple sets of main shafts of the fish skeleton.

[0021] Specifically, in this embodiment, the height of the support component 3 on the support frame 2 can be adjusted, so that the height of the support component 3 can be freely adjusted according to the degree of bending of the main shaft, thereby achieving effective support for the fish skeleton.

[0022] In some embodiments, the support component 3 described above may employ, for example... Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 The support assembly 3 includes a mounting base 31 and support rollers 32. The mounting base 31 is mounted on the support frame 2 and has a vertically adjustable position on the support frame 2. There are two support rollers 32, which are arranged parallel to each other and rotatably mounted on the mounting base 31. The axes of the support rollers 32 are arranged along the interval direction between the two placement frames 1. The mounting base 31 is mounted on the support frame 2, and two support rollers 32 are rotatably mounted on the top of the mounting base 31. When the support assembly 3 is supported on the main shaft of the fish skeleton, the main shaft of the fish skeleton is located between the two support rollers 32, thereby limiting the position of the main shaft of the fish skeleton.

[0023] Specifically, in this embodiment, after the fish skeleton is placed on the two mounting brackets 1, the height of the mounting base 31 can be adjusted so that the main shaft of the fish skeleton is positioned between the two support rollers 32, which limits the main shaft from rolling away from the support assembly 3. Simultaneously, the support rollers 32, due to the multiple web plates mounted on the fish skeleton, reduce the frictional force causing the fish skeleton to rotate freely along its main shaft axis when the two support rollers 32 lift the main shaft upwards. The design of the two support rollers 32 satisfies both the limitation of the fish skeleton's main shaft in the middle and prevents the fish skeleton from rolling on the mounting base 31 during rotation, thus improving the stability of the relative position between the fish skeleton and the support base.

[0024] In some embodiments, the support frame 2 may be adopted as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 The support frame 2 is also equipped with a base 33 for mounting the mounting seat 31. The position of the base 33 on the support frame 2 is adjustable along the length of the support frame 2. The base 33 is fixedly mounted on the support frame 2 by bolts, and the mounting seat 31 is mounted on the base 33. The position of the mounting seat 31 on the base is adjustable along the vertical direction. Multiple fish skeletons can be placed on both the placement frame 1 and the support frame 2, and the multiple fish skeletons are placed sequentially at intervals along the length of the placement frame 1 and the support frame 2. The interval direction between the two placement frames 1 is defined as the first direction, and the length direction of the placement frame 1 and the support frame 2 is defined as the second direction. Both the first direction and the second direction are horizontal and perpendicular to each other.

[0025] Specifically, in this embodiment, a base 33 is installed on the support frame 2. The position of the base 33 on the support frame 2 can be adjusted according to the placement position of the fish skeleton, so that the main shaft of the fish skeleton is directly above the two support rollers 32. Then, the height of the mounting seat 31 on the base 33 is adjusted so that the main shaft of the fish skeleton is supported between the two support rollers 32. This avoids deformation caused by long-term suspension, which would affect the later shaping of the fan blades.

[0026] In some embodiments, the mounting base 31 may be as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 At least two guide posts 331 are fixedly mounted on the side wall of the mounting base 31, and the base 33 is provided with guide holes for guiding the guide posts 331 to move up and down. Two side plates are bent upwards on the base 33, and the two side plates are arranged parallel to each other at intervals. At least two guide holes are provided on each side plate. The length direction of the guide holes is vertical. The two guide posts 331 fixed to the mounting base 31 are slidably disposed inside the guide holes. This allows the mounting base 31 to be guided to move up and down on the base 33.

[0027] Preferably, in this embodiment, the mounting base 31 is slidably disposed between two side plates on the base 33, and with the guidance of the guide post 331, the mounting base 31 can be stably slidably disposed on the base 33.

[0028] In some embodiments, the support frame 2 may be adopted as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 The support frame 2 is threaded with a fastener 332 for fixing the base 33 to the support frame 2. The base 33 has an elongated hole for mounting the fastener 332. The fastener 332 is a bolt, and the length of the elongated hole is along the length of the support frame 2. When it is necessary to adjust the position of the base 33, the fastener 332 can be loosened to adjust the position of the base 33. After the position is adjusted, the base 33 is fixed to the support frame 2 by the fastener 332. The position of the base 33 can be freely adjusted according to the placement position of the fish skeleton, and the two support rollers 32 can effectively support the main shaft of the fish skeleton.

[0029] Preferably, in this embodiment, during the conventional placement of the fish skeleton, a hoisting device or forklift is used to place the fish skeleton according to the positions of the two support rollers 32, so that the main shaft of the fish skeleton is placed between the two support rollers 32. When the fish skeleton model changes, and it is necessary to adjust the placement gap between two adjacent fish skeletons, the position of the base 33 is adjusted by loosening the bolts to support the middle of the fish skeleton when storing fish skeletons of different specifications. This is suitable for supporting the middle of fish skeletons of different specifications during placement. At the same time, when initially adjusting the relative positions of the placement frame 1 and the support frame 2, the position of the base 33 can also be finely adjusted to ensure that the placement position on the placement frame 1 corresponds to the support position on the support frame 2.

[0030] In some embodiments, the base 33 may be as follows: Figure 3 The structure shown. See also Figure 3 A wedge block 4 is slidably mounted on the base 33, and the wedge block 4 is supported on the bottom of the mounting base 31. A pusher 41 for moving the wedge block 4 is also provided on the base 33. The top surface of the wedge block 4 is inclined. A guide surface is provided at the bottom of the mounting base 31 to slide in conjunction with the top surface of the wedge block 4. When the wedge block 4 slides on the base 33, the top surface of the wedge block 4 slides in conjunction with the guide surface of the mounting base 31, causing the mounting base 31 to move up and down. This allows for adjustment of the height of the mounting base 31.

[0031] Specifically, in this embodiment, the pusher 41 is a bolt, and wing plates protrude from both sides of the wedge block 4. The pusher 41 passes through the wing plates and is threadedly connected to the base 33. Thus, when the pusher 41 is rotated, it can push the wedge block 4 to move inward into the base 33, thereby causing the mounting base 31 to move upward.

[0032] Preferably, in this embodiment, a nut that is threadedly connected to the pusher 41 and a clearance hole for avoiding the pusher 41 are fixedly installed on the base 33, thereby realizing the threaded connection between the pusher 41 and the base 33.

[0033] In some embodiments, the aforementioned pusher 41 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 The pusher 41 is threadedly connected to the base 33, and one end of the pusher 41 is provided with an abutting part for abutting against the outer wall of the wedge block 4.

[0034] Preferably, in this embodiment, a nut threadedly connected to the pusher 41 and a clearance hole for avoiding the pusher 41 are fixedly installed on the base 33, thereby realizing the threaded connection between the pusher 41 and the base 33. The pusher 41 is a bolt. When the pusher 41 is rotated, the contact part of the bolt abuts against the outer side of the wedge block 4 and pushes the wedge block 4 to slide on the base 33.

[0035] Specifically, in this embodiment, a through hole for mounting the pusher 41 is provided on the wedge block 4, and the outer diameter of the contact part is larger than the inner diameter of the through hole.

[0036] Preferably, in this embodiment, an elastic element, which is a spring, is also fitted on the outside of the pusher 41. One end of the elastic element abuts against the base 33, and the other end abuts against the wedge block 4, for pushing the wedge block 4 to move outward. This facilitates the reduction of the height of the mounting base 31 in the later stages.

[0037] In some embodiments, the base 33 may be as follows: Figure 3 The structure shown. See also Figure 3 Two wedge-shaped blocks 4 are slidably mounted on the base 33, and the two wedge-shaped blocks 4 are positioned opposite each other along the sliding direction. Two guide surfaces are inclinedly arranged at the bottom of the mounting base 31, and the two guide surfaces are parallel to the inclined surfaces at the top of the wedge-shaped blocks 4, and are clamped between the two wedge-shaped blocks 4. This design of the two wedge-shaped blocks 4 effectively supports the mounting base 31, improving its stability.

[0038] In some embodiments, the aforementioned placement rack 1 may be as follows: Figure 1 The structure shown. See also Figure 1 Multiple limiting blocks 11 are fixedly installed on the placement rack 1. Two adjacent limiting blocks 11 form a placement groove for placing the end of the fish skeleton. Multiple limiting blocks 11 are fixedly installed on the top of the placement rack 1. Two adjacent limiting blocks 11 are spaced apart to form a placement gap for placing the main shaft of the fish skeleton. When placing the fish skeleton, the main shaft of the fish skeleton is positioned between two limiting blocks 11 to reduce the rolling of the fish skeleton on the placement rack 1.

[0039] Preferably, in this embodiment, the limiting block 11 is made of wood and is fixedly installed on the top of the placement frame 1 with bolts. The wooden block can prevent damage to the main shaft of the fish skeleton and plays a protective role.

[0040] In some embodiments, the placement rack 1 and the support frame 2 can be adopted as follows: Figure 1 The structure shown. See also Figure 1 The bottom of the placement rack 1 and the support rack 2 is equipped with multiple height-adjustable support legs 5. Support legs 5 are installed at each of the four corners of the placement rack 1 and the support rack 2. Each support leg 5 includes a screw threaded to the bottom of the placement rack 1 or the support rack 2, and a base fixedly installed at the bottom of the screw. By rotating the screw, the height of the base relative to the placement rack 1 or the support rack 2 can be adjusted, thereby achieving adjustment of the height and tilt angle of the placement rack 1 or the support rack 2.

[0041] Preferably, in this embodiment, when the fish skeleton is long, the number of support frames 2 can be increased between the two placement frames 1. Multiple support frames 2 are arranged between the two placement frames 1 to effectively support the fish skeleton.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
