Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and in particular to a clamping tool. Background Technology

[0002] In wind turbine generator sets, steel-concrete composite towers adopt a hollow steel-concrete composite structure, which contains inner and outer steel pipes with concrete in between. This type of steel-concrete composite structure is called hollow sandwich steel-concrete composite.

[0003] During concrete pouring, the hydrostatic pressure of the liquid core concrete and the pouring pressure are simultaneously transmitted to the inner and outer steel pipes. Under this stress, the inner and outer steel pipes are prone to deformation, which leads to instability of the inner and outer steel pipe structures during the concrete pouring process and ultimately affects the formation of the tower.

[0004] Current technology typically involves welding reinforcing rings into the inner steel cylinder of the tower to alleviate the aforementioned casting pressure. However, the reinforcing ring is a one-piece structure, which cannot meet the support requirements of more tower models and lacks the ability to be adjusted for reuse. Therefore, the applicability of this reinforcing ring is limited. Utility Model Content

The following description of embodiments is merely intended to provide a better understanding of this utility model by illustrating examples of it. In the accompanying drawings and the following description, at least some well-known structures and techniques have not been shown to avoid unnecessarily obscuring the utility model; and, for clarity, the dimensions of some structures may be exaggerated. Furthermore, the features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments.

[0032] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the clamping fixture of this utility model. It should also be noted in the description of this utility model that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] To better understand this utility model, the following is in conjunction with... Figures 1 to 6 The clamping fixture of the present invention will be described in detail.

[0034] Please see Figures 1 to 3According to an embodiment of the present invention, a clamping fixture 100 is provided for a tower section 200. The tower section 200 includes an inner cylinder 201, an outer cylinder 202, and an intermediate body 203 located between the two. The clamping fixture 100 includes a plurality of clamping modules 101, which are distributed along a circular trajectory and enclose a hollow cavity that is disposed through the first direction Z. Each clamping module 101 includes a first clamping member 10, a second clamping member 20, and a connecting member 30. The first clamping member 10 extends a predetermined height along the first direction Z and is configured... To abut against the inner wall of the inner cylinder 201 on the side opposite to the outer cylinder 202; the second clamping member 20 is disposed on the side of the first clamping member 10 opposite to the hollow cavity, the second clamping member 20 and the first clamping member 10 are spaced apart and a gap is formed, the gap accommodates the tower section 200 and the second clamping member 20 can abut against the outer wall of the outer cylinder 202 on the side opposite to the inner cylinder 201; the connecting member 30 extends along the arrangement direction of the first clamping member 10 and the second clamping member 20 and is connected to the first clamping member 10 and the second clamping member 20 respectively, wherein the length dimension of the connecting member 30 along the arrangement direction is adjustable.

[0035] The clamping fixture 100 in this embodiment can be used in the process of forming the tower section 200 in the wind turbine generator set. Optionally, the tower section 200 can be a steel pipe concrete tower section 200, wherein the inner cylinder 201 and the outer cylinder 202 can be steel pipes with different diameters, and the intermediate body 203 between them can be cast concrete, thereby forming a complete tower section 200 structure.

[0036] In this embodiment, the main consideration is that during the molding process of the tower section 200, the casting pressure will be applied to the inner cylinder 201 and outer cylinder 202 on both sides when the intermediate body 203 is poured, which may easily cause deformation of the inner cylinder 201 and outer cylinder 202. Therefore, the clamping fixture 100 in this embodiment is set to maintain the overall stability of the structure.

[0037] Specifically, the clamping fixture 100 includes multiple clamping modules 101, and adjacent clamping modules 101 form an enclosure along a circular trajectory to adapt to the corresponding tower section 200 structure; optionally, adjacent clamping modules 101 can be connected or spaced apart from each other, and this application does not limit this.

[0038] Each clamping module 101 specifically includes a first clamping member 10, a second clamping member 20, and a connecting member 30. This application does not impose special limitations on the specific structure of the above components, as long as they can perform their respective functions.

[0039] The first clamping member 10 is used to abut against the inner wall of the inner cylinder 201. When the intermediate body 203 is poured, it can provide certain support for the inner cylinder 201 and reduce the risk of deformation of the inner cylinder 201. The second clamping member 20 is used to abut against the outer wall of the outer cylinder 202. When the intermediate body 203 is poured, it can provide certain support for the outer cylinder 202 and reduce the risk of deformation of the outer cylinder 202. The two are connected by a connector 30 to ensure that the distance between them does not change and to overcome the pressure generated during the pouring process.

[0040] Optionally, the length of the connector 30 between the two clamping members is adjustable, so that the gap between the two clamping members is adjustable to adapt to the casting of different types of tower sections 200, ensuring that the first clamping member 10 and the second clamping member 20 can fully abut against the inner cylinder 201 and the outer cylinder 202 of the tower section 200, and ensuring the clamping strength of the tower section 200. This application does not make any special limitation on the specific adjustment method of the connector 30.

[0041] This utility model embodiment provides a clamping fixture 100. The clamping fixture 100 is configured as a structure in which multiple clamping modules 101 are spliced ​​along a circular trajectory. Each clamping module 101 consists of a first clamping member 10, a second clamping member 20, and a connecting member 30. This allows for disassembly and adjustment between adjacent clamping modules 101. The first clamping member 10 effectively abuts against the inner cylinder 201 of the tower section 200, and the second clamping member 20 effectively abuts against the outer cylinder 202 of the tower section 200. This facilitates the intermediate body 20 of the tower section 200. During the casting process of section 3, reliable support is simultaneously formed for the inner cylinder 201 and the outer cylinder 202, reducing the risk of deformation of the inner cylinder 201 and the outer cylinder 202, and improving the structural stability of the tower section 200 during the molding process. At the same time, the length of the connecting piece 30 between the first clamping member 10 and the second clamping member 20 is adjustable, so that each clamping module 101 has the ability to adjust its size, ensuring that the clamping fixture 100 as a whole can be applied to the molding of more types of tower sections 200, thus having a better range of applications and meeting the support needs of more tower sections 200 during the molding process.

[0042] As an optional embodiment, please refer to Figure 1 and Figure 2 In the plurality of clamping modules 101, two adjacent first clamping members 10 are detachably connected to each other; and / or, two adjacent second clamping members 20 are detachably connected.

[0043] To further ensure the structural strength between adjacent clamping modules 101, a detachable connection can be formed between adjacent clamping modules 101 in this embodiment. Specifically, it can be a detachable connection between the first clamping members 10 or a detachable connection between the second clamping members 20. Of course, both can also be detachably connected simultaneously.

[0044] As shown in the figure, the first clamping member 10 and the second clamping member 20 shown in the figure are detachably connected. Specifically, they can be connected by bolts. Threaded holes can be opened on the side walls of the first clamping member 10 and the second clamping member 20. This application does not make any special limitation on the specific detachable connection method, but only uses the bolt connection method as a feasible example.

[0045] When the clamping fixture 100 is needed for support during forming, the inner cylinder 201 and the outer cylinder 202 can be placed in a predetermined position first. Then, each clamping module 101 is installed and clamped at the inner cylinder 201 and the outer cylinder 202. By adjusting the length of the connecting piece 30, the clamping pieces are made to abut against the cylinder wall. Then, the adjacent clamping modules 101 are connected by the bolt connection method described above, thereby forming a complete ring structure.

[0046] This utility model provides a clamping fixture 100, which forms a detachable connection between adjacent first clamping member 10 and second clamping member 20. While using the clamping members to support the tower section 200, it further improves the stability of the ring structure, giving it better structural strength and providing a guarantee for stable and reliable clamping.

[0047] As an optional embodiment, please refer to Figure 1 and Figure 2 A plurality of first clamping members 10 are connected to form one of a circular ring and a polygonal ring; and / or a plurality of second clamping members 20 are connected to form one of a circular ring and a polygonal ring.

[0048] Optionally, the first clamping member 10 and the second clamping member 20 can be set as arc-shaped structures, so that after the enclosure is formed, a complete annular structure is obtained. The clamping fixture 100 as a whole forms a structure of two coaxial annular rings, which match the inner cylinder 201 and outer cylinder 202 of the tower section 200, ensuring the contact between the clamping member and the cylinder wall.

[0049] Of course, the clamping fixture 100 can be enclosed as a whole to form two coaxial polygonal ring structures according to the actual structure of the tower section 200, so as to meet the forming requirements of tower sections 200 of different shapes. At this time, the corresponding first clamping member 10 and second clamping member 20 are linear structures. This application does not make any special limitation on the specific structure of the clamping member.

[0050] This utility model provides a clamping fixture 100. By utilizing the enclosure of multiple clamping components, the clamping fixture 100 can form a circular ring structure or a polygonal structure, thereby enabling it to clamp and match tower sections 200 of different shapes, meeting the forming requirements of more tower sections 200 and having better adaptability.

[0051] As an optional embodiment, please refer to Figure 4 The connector 30 includes a first connecting part 31 and a second connecting part 32. The first connecting part 31 is disposed on the first clamping member 10 and the second connecting part 32 is disposed on the second clamping member 20. The relative positions of the first connecting part 31 and the second connecting part 32 in the arrangement direction are adjustable.

[0052] Regarding the adjustable length of the connector 30, in this embodiment, the connector 30 is configured as a first connecting part 31 and a second connecting part 32. Specifically, the first connecting part 31 is disposed on the first clamping member 10 and the second connecting part 32 is disposed on the second clamping member 20. Optionally, the two connecting parts can be plate-shaped structures, which is not limited in this application.

[0053] Making the length of the connector 30 adjustable is actually adjusting the relative position of the first connecting part 31 and the second connecting part 32. For example, the two connecting parts can be stacked one on top of the other, and the overall length of the connector 30 can be adjusted by shifting them.

[0054] Of course, the connecting member 30 can also be designed as an integral structure, for example, it can be a telescopic cylinder such as a pneumatic cylinder or a hydraulic cylinder, which can adjust the length by its own telescopic performance. This application does not limit this.

[0055] This utility model embodiment provides a clamping fixture 100. By setting the connector 30 as a first connecting part 31 and a second connecting part 32, the overall length of the connector 30 can be adjusted by adjusting the relative positional relationship between the two. This makes the adjustment process simpler and easier to operate, reduces the adjustment difficulty for workers, and also facilitates the separation of the first clamping part 10 and the second clamping part 20, resulting in more diverse component assembly and disassembly.

[0056] As an optional embodiment, the first connecting part 31 is provided with a first connecting hole, and the second connecting part 32 is provided with a second connecting hole. The first connecting hole and the second connecting hole are provided correspondingly, and one of them is an elongated hole that extends in the arrangement direction. The first connecting part 31 and the second connecting part 32 are detachably connected by a first fastener inserted into the first connecting hole and the second connecting hole.

[0057] Specifically, regarding the connection between the first connecting part 31 and the second connecting part 32, a detachable connection can be formed between them. In this embodiment, a first connecting hole and a second connecting hole are respectively provided on both, such as threaded holes. The connection is completed by inserting a first fastener into the two connecting holes.

[0058] In order to make the length of the connector 30 adjustable, in this embodiment, one of the first connecting hole and the second connecting hole is set as an elongated hole. By adjusting the connection position of the first fastener in the elongated hole, the overall length of the connector 30 can be adjusted. The above-mentioned bolt connection method is a reliable detachable connection method.

[0059] Of course, the above-mentioned connection method through the first connecting hole and the second connecting hole is only a feasible example. The first connecting part 31 and the second connecting part 32 can also be connected by magnetic attraction, and the overall length of the connector 30 can be adjusted by the misalignment between the two. The length adjustment of the connector 30 can also be completed. This application does not limit this.

[0060] This utility model embodiment provides a clamping fixture 100, which utilizes a first connecting hole and a second connecting hole, with one of them being an elongated hole, to achieve adjustment of the overall length of the connector 30, while also satisfying the detachable connection between the clamping components and ensuring the connection strength between the clamping components.

[0061] As an optional embodiment, please refer to Figure 4 The connector 30 has a relief groove 33, which is recessed away from the gap and has its opening facing the gap.

[0062] Since the first clamping member 10 and the second clamping member 20 are spaced apart and form a gap to meet the clamping requirements of the inner cylinder 201 and the outer cylinder 202, in order to smoothly cast the intermediate body 203 after the clamping fixture 100 clamps the tower section 200, the connecting member 30 is set to a structure with a relief groove 33 in this embodiment.

[0063] Specifically, the opening of the clearance groove 33 needs to face the gap between the two, so that the connector 30 can cross the gap between the two clamping members, avoiding the obstruction of the connector 30 to the pouring in the gap.

[0064] This utility model embodiment provides a clamping fixture 100. By setting an avoidance groove 33 on the connector 30, the structural characteristics of the avoidance groove 33 can avoid affecting the casting of the intermediate gap. While ensuring the connection stability of the two clamping parts, it is convenient to complete the casting process of the intermediate body 203.

[0065] As an optional embodiment, please refer to Figure 4At least one of the first clamping member 10 and the second clamping member 20 includes a transition body 40 and a pair of reinforcing bodies 50. The pair of reinforcing bodies 50 are spaced apart along the first direction Z. The transition body 40 is connected between the pair of reinforcing bodies 50. The reinforcing bodies 50 of two adjacent clamping modules 101 are in contact with each other.

[0066] Regarding the specific structure of the first clamping member 10 and the second clamping member 20, in this embodiment, the structure is set as a pair of reinforcing bodies 50 and a transition body 40 connecting the two. Specifically, the pair of reinforcing bodies 50 can form an abutment with the cylinder wall.

[0067] Optionally, the adapter 40 extends along the first direction Z and connects between the two reinforcing bodies 50, so that each clamping member can have a certain height in the first direction Z to meet the support requirements of the tower section 200 in the height direction; at the same time, the contact between the reinforcing body 50 and the cylinder wall can further improve the support capacity of the tower section 200. Optionally, the reinforcing body 50 can adopt a block structure to form a more stable contact. This application does not make any special limitation on the specific structure of the reinforcing body 50.

[0068] This utility model provides a clamping fixture 100, which can simultaneously abut against the tower section 200 by utilizing two reinforcing bodies 50 in the first direction Z, thereby ensuring the clamping stability in the first direction Z. The reinforcing bodies 50 can fully absorb the casting pressure and improve the structural strength of the clamping fixture 100 itself.

[0069] As an optional embodiment, please refer to Figure 4 The orthographic projections of the paired reinforcements 50 in the first direction Z coincide.

[0070] This utility model embodiment provides a clamping fixture 100. By having two reinforcing bodies 50 in each clamping member correspondingly arranged in the first direction Z, the abutment accuracy of the reinforcing bodies 50 in the first direction Z is ensured, so that the inner cylinder 201 and the outer cylinder 202 will not tilt in the first direction Z during the casting process, thereby improving the clamping reliability of the tower section 200.

[0071] As an optional embodiment, the height dimension of the adapter 40 in the first direction Z is adjustable.

[0072] For the adapter 40 between the two reinforcing bodies 50 in the clamping member, in this embodiment, the height dimension of the adapter 40 in the first direction Z can be set to an adjustable dimension, so that the adapter 40 has an adjustable capability in the first direction Z.

[0073] Optionally, the adapter 40 can be configured as an integral structure, such as a telescopic cylinder structure, or it can be a split structure. This application is not limited to this, as long as the size of the adapter 40 in the first direction Z is adjustable.

[0074] This utility model provides a clamping fixture 100. By making the height dimension of the adapter 40 adjustable in the first direction Z, the clamping component as a whole can be adjusted in the first direction Z, thereby better meeting the clamping requirements of tower sections 200 of different heights, adapting to tower sections 200 of different heights to clamp them more fully, and having better clamping stability.

[0075] As an optional embodiment, please refer to Figure 4 The adapter 40 includes a first adapter part 41 and a second adapter part 42. The first adapter part 41 is connected to one of the paired reinforcing bodies 50 and the second adapter part 42 is connected to the other. The first adapter part 41 and the second adapter part 42 are movably connected in a first direction Z.

[0076] Regarding the adjustable height of the adapter 40, in this embodiment, the adapter 40 is configured as a first adapter part 41 and a second adapter part 42. Specifically, the first adapter part 41 is disposed on one of the reinforcing bodies 50 and the second adapter part 42 is disposed on the other reinforcing body 50. Optionally, the two adapter parts can be plate-shaped structures, which is not limited in this application.

[0077] Adjusting the height of the adapter 40 itself is actually adjusting the relative position of the first adapter 41 and the second adapter 42. For example, the two adapters can be stacked and connected left and right, and the overall length of the adapter 40 can be adjusted by moving them up and down in a staggered manner.

[0078] Of course, the adapter 40 can also be designed as an integral structure, for example, it can be a telescopic cylinder such as a pneumatic cylinder or a hydraulic cylinder, which can adjust the height by its telescopic performance. This application does not limit this.

[0079] This utility model embodiment provides a clamping fixture 100. By setting the adapter 40 into a structure of a first adapter part 41 and a second adapter part 42, the overall height of the adapter 40 can be adjusted by adjusting the relative positional relationship between the two, making the adjustment process simpler and easier to operate, reducing the adjustment difficulty for workers, and also facilitating the separation of the upper and lower parts of each clamping component, forming more diverse component assembly and disassembly.

[0080] As an optional embodiment, please refer to Figure 5 and Figure 6The first adapter 41 is provided with a first adapter hole 1, and the second adapter 42 is provided with a second adapter hole 2. The first adapter hole 1 and the second adapter hole 2 are provided correspondingly, and one of them is an elongated hole. The elongated hole extends in the first direction Z. The first adapter 41 and the second adapter 42 are detachably connected by a second fastener inserted into the first adapter hole 1 and the second adapter hole 2.

[0081] Specifically, regarding the connection between the first adapter 41 and the second adapter 42, a detachable connection can be formed between them. In this embodiment, a first adapter hole 1 and a second adapter hole 2 are respectively provided on both, such as threaded holes. The connection is completed by inserting a second fastener into the two adapter holes.

[0082] In order to make the height of the adapter 40 adjustable, in this embodiment, one of the first adapter hole 1 and the second adapter hole 2 is set as an elongated hole. By adjusting the connection position of the second fastener in the elongated hole, the overall height of the adapter 40 can be adjusted. The above-mentioned bolt connection method is a reliable detachable connection method.

[0083] Of course, the above-mentioned connection method through the first adapter hole 1 and the second adapter hole 2 is only a feasible example. The first adapter part 41 and the second adapter part 42 can also be connected by magnetic attraction, and the overall height of the adapter body 40 can be adjusted by the misalignment movement between the two. The height adjustment of the adapter body 40 can also be achieved. This application does not limit this.

[0084] This utility model embodiment provides a clamping fixture 100. By utilizing the first adapter hole 1 and the second adapter hole 2, and setting one of them as an elongated hole, the overall height of the adapter body 40 is adjusted. At the same time, it satisfies the detachable connection of each clamping component and ensures the connection strength of the clamping component itself.

[0085] As an optional embodiment, please refer to Figure 5 The reinforcing body 50 includes a first reinforcing plate 51 and a second reinforcing plate 52 disposed opposite to each other in the first direction Z, and a plurality of connecting plates 53 connected between the two. The connecting plates 53 together with the first reinforcing plate 51 and the second reinforcing plate 52 form a plurality of supporting cavities 54.

[0086] Optionally, the reinforcing body 50 may be formed by connecting a first reinforcing plate 51, a second reinforcing plate 52 and a plurality of connecting plates 53. The plurality of connecting plates 53 are connected between the two reinforcing plates, thereby dividing the space between the two reinforcing plates into a plurality of supporting cavities 54. This application does not impose any special limitation on the specific structure and number of the formed supporting cavities 54. The supporting cavities 54 can better absorb the casting stress, thereby making the overall structure have better buffering capacity.

[0087] This utility model embodiment provides a clamping fixture 100 and a feasible structural form of a reinforcing body 50. By setting the reinforcing body 50 as a structure with multiple supporting cavities 54, it can better buffer stress and also help reduce the overall weight of the fixture, making the overall structure lighter and easier to adjust.

[0088] This utility model provides a clamping fixture, which is configured as a structure in which multiple clamping modules are spliced ​​along a circular trajectory. Each clamping module consists of a first clamping member, a second clamping member, and a connecting member. This allows for disassembly and adjustment between adjacent clamping modules. The first clamping member effectively abuts against the inner cylinder of the tower section, and the second clamping member effectively abuts against the outer cylinder of the tower section. This provides reliable support for both the inner and outer cylinders during the casting of the intermediate body of the tower section, reducing the risk of deformation of the inner and outer cylinders and improving the structural stability of the tower section during the molding process. Furthermore, the length of the connecting member between the first and second clamping members is adjustable, allowing each clamping module to have dimensional adjustment capabilities. This ensures that the clamping fixture as a whole can be applied to the molding of more types of tower sections, thus having a wider range of applications and meeting the support needs of more tower sections during the molding process.

[0089] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
