Description

Technical Field

[0001] This utility model relates to the field of wind turbine hub clamping technology, and more specifically, to a multi-functional safety locking clamp for wind turbine hub hoisting. Background Technology

[0002] When the wheel hub is lifted by a crane, the clamps use a mechanical locking mechanism to tightly connect the wheel hub to the lifting device or tower flange, preventing the wheel hub from falling off due to vibration, wind load or operational errors, and ensuring safety during high-altitude operations.

[0003] Among existing published documents, patent publication number CN204366797U discloses a wheel hub bearing fixing clamp. This technology uses a semi-circular locking rod slidably connected within a dovetail groove. Half of the locking rod slides into the dovetail groove within the first clamping part. Since one end of the locking rod is in the dovetail groove on the first clamping part and the other end is in the dovetail groove on the second clamping part, the second clamping part is prevented from sliding, making it convenient and quick to fix. Furthermore, the locking rod being within the dovetail groove effectively prevents it from being lost. However, this patent has the following drawbacks.

[0004] During the hoisting of wind turbine hubs, although it is possible to clamp the wind turbine hubs, it is difficult to achieve horizontal and vertical locking during the clamping process. This results in poor bidirectional embedding and locking after locking, and the stability of the locking installation is poor. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a multi-functional safety locking clamp for hoisting wind turbine hubs, comprising a locking groove plate, an arc-shaped clamping plate slidably connected to the upper surface of the locking groove plate, a positioning plate provided on one side of the arc-shaped clamping plate, the positioning plate being fixedly connected to the locking groove plate, and a bidirectional engagement locking assembly installed on the inner wall of the locking groove plate, the bidirectional engagement locking assembly comprising:

[0006] A socket block is slidably connected to the inner wall of the locking groove plate. A transverse screw is threaded to the inner wall of the socket block, and the transverse screw is rotatably connected to the locking groove plate.

[0007] A longitudinal screw is fixedly connected to one side of the outer wall of the sleeve block, and a silicone sheet is rotatably mounted on the outer wall of the longitudinal screw.

[0008] A locking nut is fixedly connected to one side of the silicone sheet, and the locking nut is threadedly connected to the longitudinal screw.

[0009] Both racks are fixedly connected to one side of the outer wall of the locking groove plate, and the locking nut is used to rotate and drive the silicone sheet to press against the rack.

[0010] In a preferred embodiment, the arc-shaped clamping plate and the positioning plate have a circular arc cross-sectional shape, and a gap is provided between the arc-shaped clamping plate and the positioning plate.

[0011] In a preferred embodiment, the outer wall of the socket block and the inner wall of the locking groove plate are both smooth surfaces, and both the socket block and the locking groove plate are made of stainless steel.

[0012] In a preferred embodiment, a rotating cap is fixedly connected to one end of the socket block, and the vertical cross-sectional shape of the rotating cap is polygonal.

[0013] In a preferred embodiment, a groove is provided on one side of the longitudinal screw, and the longitudinal screw is slidably connected to the locking groove plate to which the groove belongs.

[0014] In a preferred embodiment, a hanging column is fixedly connected to the upper surface of the locking groove plate and near its top end;

[0015] The top of the lifting column is fixedly connected to a main lifting ring, and a bracket is provided on one side of the lifting column. The bracket is fixedly connected to the locking groove plate, and a secondary lifting ring is fixedly installed on the top of the bracket.

[0016] In a preferred embodiment, a gap is provided between the main lifting ring and the auxiliary lifting ring, and the inner walls of the main lifting ring and the auxiliary lifting ring are smooth surfaces.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] This utility model adopts a two-way meshing locking assembly. The sleeve block drives the longitudinal screw to move to the right, the sleeve block drives the arc-shaped clamping plate to move to the right, the arc-shaped clamping plate squeezes the fan hub, and the locking nut drives the silicone sheet to rotate. The silicone sheet is squeezed onto the rack, thus meshing and locking the silicone sheet onto the rack. The arc-shaped clamping plate and the positioning plate are mutually limited and embedded for locking, resulting in a more secure locking installation.

[0019] 2. This utility model adopts a method of hanging a hook on the inner wall of the main lifting ring and another hook on the auxiliary lifting ring. When lifting, the main lifting ring drives the lifting column to move upward, the lifting column drives the locking groove plate to move upward, and the bracket drives the locking groove plate to move upward. In this way, the locking groove plate drives the arc-shaped clamping plate and the positioning plate to carry the wind turbine hub for double safety positioning and lifting, which makes the lifting and installation of the wind turbine hub safer.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] As attached Figure 1 - Appendix Figure 5 The present invention relates to a multi-functional safety locking clamp for hoisting wind turbine hubs. The multi-functional safety locking clamp for hoisting wind turbine hubs is equipped with a two-way engagement locking component. The two-way engagement locking component enables the arc-shaped clamp 2 and the positioning plate 3 to be locked together in both the lateral and longitudinal directions, resulting in a more secure locking installation. The specific structural configuration of the two-way engagement locking component is as follows.

[0028] In this embodiment, as shown in the appendix Figure 1 - Appendix Figure 4As shown, a positioning plate 3 is provided on one side of the arc-shaped clamping plate 2. The positioning plate 3 is fixedly connected to the locking groove plate 1. A two-way meshing locking assembly is installed on the inner wall of the locking groove plate 1. The two-way meshing locking assembly includes: a sleeve block 4, which is slidably connected to the inner wall of the locking groove plate 1. A transverse screw 5 is threadedly connected to the inner wall of the sleeve block 4. The transverse screw 5 is rotatably connected to the locking groove plate 1. A longitudinal screw 6 is fixedly connected to one side of the outer wall of the sleeve block 4. A silicone sheet 7 is rotatably installed on the outer wall of the longitudinal screw 6. A locking nut 8 is fixedly connected to one side of the silicone sheet 7. The locking nut 8 is threadedly connected to the longitudinal screw 6. Two racks 9 are fixedly connected to one side of the outer wall of the locking groove plate 1. The locking nut 8 is used to rotate and drive the silicone sheet 7 to press against the racks 9. The arc-shaped clamping plate 2 and the positioning plate 3 have a circular arc shape in cross-section. A gap is provided between the arc-shaped clamping plate 2 and the positioning plate 3. The outer wall of the socket block 4 and the inner wall of the locking groove plate 1 are both smooth surfaces, and both the socket block 4 and the locking groove plate 1 are made of stainless steel.

[0029] In this embodiment, as shown in the appendix Figure 3 As shown, a rotating cap 10 is fixedly connected to one end of the socket block 4, and the vertical cross-section of the rotating cap 10 is polygonal, so that the rotating cap 10 can be rotated by a wrench. The rotating cap 10 drives the horizontal screw 5 to rotate, thereby realizing the rotation operation of the horizontal screw 5.

[0030] In this embodiment, as shown in the appendix Figure 2 As shown, a groove 11 is provided on one side of the longitudinal screw 6. The longitudinal screw 6 is slidably connected to the locking groove plate 1 to which the groove 11 belongs, so that the longitudinal screw 6 can be guided and slid along the inside of the groove 11, and the sliding stability is better.

[0031] This multi-functional safety locking clamp for wind turbine hub hoisting involves placing the wind turbine hub in the gap between the arc-shaped clamp 2 and the positioning plate 3. A wrench is used to rotate the rotating cap 10, which in turn rotates the transverse screw 5. The transverse screw 5 rotates within the locking groove 1, simultaneously causing the sleeve block 4 to move to the right under the force transmitted through the thread. The sleeve block 4 also moves to the right along the inner wall of the locking groove 1, limiting its movement. Furthermore, the sleeve block 4 causes the longitudinal screw 6 to move to the right, which in turn causes the locking nut 8 to move to the right. The locking nut 8 then causes the silicone sheet 7 to move to the right, thus moving the silicone sheet 7 along the rack 9. The sleeve block 4 then moves the arc-shaped clamp... Plate 2 moves to the right, and the arc-shaped clamp 2 presses against the fan hub, fixing the fan hub in the gap between the arc-shaped clamp 2 and the positioning plate 3. This achieves lateral locking of the fan hub. Then, the locking nut 8 is turned with a wrench, which drives the silicone sheet 7 to rotate. The silicone sheet 7 presses against the rack 9, locking the silicone sheet 7 onto the rack 9. This achieves longitudinal locking of the longitudinal screw 6. Thus, the arc-shaped clamp 2 and the positioning plate 3 achieve lateral and longitudinal limiting locking. The hub is bidirectionally and safely locked between the positioning plate 3 and the sleeve block 4. This not only provides better locking firmness but also better locking safety and positioning clamping effect.

[0032] In this embodiment, as shown in the appendix Figure 5 As shown, a lifting column 12 is fixedly connected to the upper surface of the locking groove plate 1 near its top. A main lifting ring 13 is fixedly connected to the top of the lifting column 12, and a bracket 14 is provided on one side of the lifting column 12. The bracket 14 is fixedly connected to the locking groove plate 1, and a secondary lifting ring 15 is fixedly installed at the top of the bracket 14. There is a gap between the main lifting ring 13 and the secondary lifting ring 15, and the inner walls of the main lifting ring 13 and the secondary lifting ring 15 are smooth surfaces.

[0033] When using this multi-functional safety locking clamp for wind turbine hub hoisting, the hook is hung on the inner wall of the main lifting ring 13, and the other hook is hung on the auxiliary lifting ring 15. In this way, there are two hooks at each corner of the locking groove plate 1 for synchronous engagement. When lifting, the main lifting ring 13 moves the lifting column 12 upward, and the lifting column 12 moves the locking groove plate 1 upward. At the same time, the auxiliary lifting ring 15 lifts and moves the bracket 14 upward, and the bracket 14 moves the locking groove plate 1 upward.

[0034] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
