In the drawings, the size of the components and the like may be adaptively enlarged or reduced for clarity. Wherein like reference numerals refer to like elements throughout.

In the present disclosure, the terms "first," "second," and "second" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implying a number of technical features being indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, unless otherwise indicated, the meaning of "a plurality" is two or more.

The described features, structures, or characteristics of the utility model may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the utility model. One skilled in the relevant art will recognize, however, that the inventive aspects may be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the utility model.

The guiding and aligning device according to an embodiment of the present utility model may be applied to flanges of two components in a wind power generation set, i.e., the components to be connected, which will be described below, may be flanges. However, the application of the guide device according to the embodiment of the present utility model is not limited thereto, but it may be applied to other work pieces having holes that are required to achieve guide alignment according to actual circumstances.

A guide apparatus according to an embodiment of the present utility model will be described below with reference to fig. 1 to 5.

Referring first to fig. 3, the guide apparatus according to an embodiment of the present utility model may include at least one guide bar 100-3. The guide bar 100-3 includes, in order from a first end toward a second end in a length direction thereof, a first connection portion 110, a first guide portion 120, a force application portion 140, and a guide portion 150 connected to each other, wherein the first connection portion 110 is for connection with a first connection hole 201 on a first member to be connected 200 (see fig. 5, 6), and a diameter of the first guide portion 120 is greater than a diameter of the force application portion 140 and a diameter of the guide portion 150, respectively. The first guide portion 120 is configured to be disposed in a second connection hole 301 of a second member 300 to be connected (see fig. 5 and 6), and to be in contact engagement with the second connection hole 301. The first guide portion 120 and the urging portion 140 are smoothly or smoothly transitioned therebetween.

The first connection portion 110 may be a threaded portion, but the present utility model is not limited thereto as long as it is detachably connected to the first part to be connected 200 each other.

Since the diameter of the first guide 120 is larger than the diameter of the force application part 140 and the diameter of the guide 150, respectively, it can be used to precisely align the members to be connected during the guide alignment process. In addition, since the first aligning portion 120 and the force applying portion 140 smoothly transition or smoothly transition, the aligning device according to the embodiment of the present utility model can be easily detached after the alignment is completed.

In the process of connecting the first connecting portion 110 and the first part to be connected 200 to each other and disconnecting the first connecting portion 110 from the first part to be connected 200, the force applying portion 140 may be engaged with a machine tool (e.g., a hydraulic wrench, an electric wrench, and a hydraulic tensioner) to perform the above-described connection and disconnection in a labor-saving and convenient manner. Of course, in the above process, the manual tools (e.g., open spanner, socket spanner, ratchet spanner) may also be used in matching.

Further modified embodiments of the guide according to the embodiment of the present utility model will be described below.

Referring to fig. 1, the guide apparatus according to an embodiment of the present utility model may include at least one guide bar 100-1. In contrast to the guide bar 100-3 according to the embodiment of fig. 3, the guide bar 100-1 according to the embodiment of fig. 1 further comprises a first guide 130. The first guide 130 is connected between the first guide 120 and the urging portion 140 and the diameter of the first guide 130 is smaller than the diameter of the first guide 120. Smooth transition or smooth transition is formed between the first guide portion 130 and the urging portion 140 and between the first guide portion 130 and the first guide portion 120.

Referring to fig. 2, the guide apparatus according to an embodiment of the present utility model may include at least one guide bar 100-2. In contrast to the guide bar 100-1 according to the embodiment of fig. 1, the guide bar 100-2 according to the embodiment of fig. 2 further comprises a second guide 160. The second guide 160 is connected between the first guide 130 and the urging portion 140, and has the same diameter as that of the first guide 120. The second guide 160 is configured to be disposed in the second connection hole 301 of the second to-be-connected component 300 and to be in contact engagement with the second connection hole 301. Smooth transition or smooth transition is formed between the second guiding portion 160 and the first guiding portion 130 and between the second guiding portion 160 and the force applying portion 140.

Referring to fig. 4, the embodiment of the guide apparatus shown in fig. 4 is substantially identical in structural configuration to the embodiment of the guide apparatus shown in fig. 1. However, it is different from the guide bar 100-1 shown in fig. 1 in that: the length of the first guide 130 of the guide bar 100-4 shown in fig. 4 in the length direction of the guide bar may be smaller than the length of the first guide 130 of the guide bar 100-1 in the length direction, so that the length of the guide bar 100-4 in the length direction may be smaller than the length of the guide bar 100-1 in the length direction.

However, the present disclosure is not limited thereto, and still another modified example of the guide bar 100-1 of the embodiment of fig. 1 is also shown in fig. 5. As shown in the right diagram of fig. 5, the length of the first guide 130 of the guide bar 100-1 'in the length direction may be formed to be greater than the length of the first guide 130 of the guide bar 100-1 in the length direction, so that the length of the guide bar 100-1' in the length direction may be formed to be greater than the length of the guide bar 100-1 in the length direction.

In this case, since the guide according to the embodiment of the present utility model may include guide bars having different lengths, it is applicable to the members to be connected having different thicknesses. The thickness here may refer to the thickness of the members to be connected in the length direction.

As described above, the guide apparatus according to the present utility model may include at least one guide bar. However, the present utility model is not limited thereto. For example, the guide bars of the various embodiments described above may cooperate with one another to act as a set of guide guides. As an example, as shown in fig. 5, a pair of guide bars 100-1 or a pair of guide bars 100-1 and 100-1' according to the embodiment of fig. 1 may be used in cooperation with each other to serve as a set of guide means, but the present disclosure is not limited thereto. In other words, the guide device according to the present utility model may include a first guide bar and a second guide bar provided in pairs, and the lengths of the first guide bar and the second guide bar in the length direction may be the same or different. However, the present utility model is not limited thereto.

Fig. 7 and 8 are schematic views of the guide device according to the present utility model after the guide alignment, respectively.

After the alignment of the parts to be connected, the first connection portion 110 of the alignment guide according to the present utility model is connected to the first connection hole 201 of the first part to be connected 200, the first alignment portion 120 and the first connection portion 110 are connected to each other and are located in the second connection hole 301 of the second part to be connected 300, and the force application portion 140 can protrude from the second connection hole 301. The ability of the force application portion 140 to protrude from the second connection hole 301 may mean that: the end of the urging portion 140 near the first end of the guide bar is flush with the end face of the second member to be connected 300 near the second end of the guide bar, or is distant from the end face of the second member to be connected 300.

Since the first connection portion 110 is connected to the first connection hole 201 of the first part to be connected 200 and the first guide portion 120 and the first connection portion 110 are connected to each other, the moment arm of the moment to which the guide device according to the present utility model is subjected can be reduced, the moment to which the guide device is subjected can be reduced, the overall rigidity and reliability of the device can be improved, and it is unnecessary to use a special material (e.g., a collapsible material, a high-strength alloy steel) for improving the rigidity of the device, but it is possible to use a general steel, so that the overall cost of the device can be reduced.

The aperture of the first connection hole 201 of the first part to be connected 200 and the aperture of the second connection hole 301 of the second part to be connected 300 may be the same, but are not limited thereto. For example, as shown in fig. 7 and 8, the aperture of the first connection hole 201 of the first part to be connected 200 may be smaller than the aperture of the second connection hole 301 of the second part to be connected 300.

When the aperture of the first connection hole 201 of the first part to be connected is smaller than the aperture of the second connection hole 301 of the second part to be connected, the end surface of the first guide portion 120 and the end surface of the first part to be connected 200 may contact each other. In this case, since the end face of the first guide portion 120 and the end face of the first member to be connected 200 can be in contact with each other, the rigidity of the guide device according to the present utility model can be further improved.

The wall thicknesses (thicknesses in the length direction) of the first to-be-connected member 200 and the second to-be-connected member 300 may be different from each other. For example, the wall thickness of the first part to be connected 200 may be larger than the wall thickness of the second part to be connected 300 (as shown in fig. 7), or the wall thickness of the first part to be connected 200 'may be larger than the wall thickness of the second part to be connected 300' (as shown in fig. 8). However, the present utility model is not limited thereto. The wall thicknesses of the first part to be connected and the second part to be connected may be the same as each other (not shown). Therefore, the guiding and guiding device according to the utility model can be applied to parts to be connected with different thicknesses.

Fig. 9 is a schematic view of a guide portion of a guide according to the present utility model.

The shape of the guide portion 150 of the guide alignment device according to the present utility model may not be particularly limited as long as it can function to guide the to-be-connected components during the alignment of the to-be-connected components. For example, the guide 150 may have a shape in which the diameter thereof gradually decreases in the length direction, for example, the guide 150 may have a tapered shape or a frustum shape.

FIG. 10 is a schematic view of the force application portion of the guide and guide device according to the present utility model; fig. 11 is a schematic view of different cross-sectional forms of the force application portion of the guide and guide device according to the present utility model.

Referring to fig. 10 and 11, in a cross section perpendicular to the length direction, the urging portion 140 may have a hexagonal shape, a square shape, or a racetrack shape (as shown in the rightmost drawing in fig. 11). In the case where the urging portion 140 is in the shape of a hexagon, the hexagon may be a standard-sized hexagon (as shown in the left drawing in fig. 10), or may be a non-standard-sized hexagon (as shown in the right drawing in fig. 10). Further, since the urging portion has a hexagonal shape in a cross section perpendicular to the longitudinal direction, the mechanical tool can be easily used to detach the guide and guide device.

The alignment and disassembly process of the alignment guide according to the present utility model will be described with reference to fig. 6.

Referring to fig. 6, the alignment and disassembly process of the alignment guide according to the present utility model will be described by taking a pair of alignment bars 100-1 and 100-1' as an example. First, the guide bars 100-1 and 100-1' of the guide device according to the present utility model may be coupled to the first coupling holes 201 of the first part to be coupled 200, respectively. However, only one guide bar or more guide bars may be used, and the type and number of guide bars used may be determined as needed.

Next, the second to-be-connected member 300 is mounted. The second connection holes 301 of the second to-be-connected components 300 are respectively passed through the guide bars 100-1 and 100-1'. Specifically, the second connection hole 301 of the second member to be connected 300 sequentially passes through the guide portion 150, the force application portion 140, the first guide portion 130, and the first guide portion 120 until the end surface of the first member to be connected 200 and the end surface of the second member to be connected 300 are attached to each other, completing the guide alignment therebetween.

When the second connection hole 301 of the second to-be-connected member 300 sequentially passes through the guide portion 150, the force application portion 140, and the first guide portion 130, the second to-be-connected member 300 may be guided to be substantially aligned with the first to-be-connected member 200, and when the second connection hole 301 of the second to-be-connected member 300 passes through the first guide portion 120, since the diameters of the first guide portion 120 are respectively larger than those of the first guide portion 130, the force application portion 140, and the guide portion 150, the alignment degree of the second to-be-connected member 300 and the first to-be-connected member 200 may be precisely adjusted, eventually causing the end surfaces of the first to-be-connected member 200 and the second to-be-connected member 300 to be adhered to and parallel to each other, completing the alignment.

After the first to-be-connected member 200 and the second to-be-connected member 300 are connected to each other, the step of removing the guide may be performed. The step of removing the guide may be performed after the other coupling holes of the first to-be-coupled member 200 and the second to-be-coupled member 300 are coupled to each other by using a fastener such as a bolt.

In the case of detaching the guide, a mechanical tool (e.g., a hydraulic wrench, an electric wrench, and a hydraulic stretcher) may be used to act on the urging portion 140 to move the guide bar toward the end face of the second member to be connected 300 near the second end of the guide bar (as indicated by the arrow horizontally rightward in fig. 6) until the guide is detached.

As described above, since the first connecting portion is connected to the connecting hole of the first member to be connected and the urging portion can protrude from the second connecting hole, the urging moment applied can be increased, and the guide device can be detached with a more effort. Further, since the urging portion may have a hexagonal shape in a cross section perpendicular to the longitudinal direction, the mechanical tool can be easily used, and the guide can be easily detached.

Since the diameter of the guide portion is larger than the diameters of the guide portion, the urging portion, and the guide portion, only the guide portion can be pressed after the guide alignment is completed, so that the friction force born by the entire guide device can be reduced, and the guide device can be detached more easily.

The guide and guide device provided by the utility model has the advantages of simple structure, capability of accurately realizing guide and guide alignment, easiness in disassembly and low overall cost.

The guide and guide device according to the present utility model can also be applied to guide and guide members of different thicknesses.

The guiding and guiding device can be matched with a plurality of guiding rods of different types or the same type, and can be uniformly applied to a hoisting link and a final assembly link of a wind generating set, so that design resources can be saved.

While the present utility model has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present utility model as defined by the following claims.
