Description

Technical Field

[0001] The utility model relates to the technical field of component storage equipment, and more specifically, to a self-aligning support device for rotary components. Background Art

[0002] During the production and assembly of wind turbines, support tools are required for storing rotary components such as rotors. For large rotors, they need to be rotated during the support process to facilitate the installation of components and other operations. It is required that a roller device be used at the contact part between the support tool and the rotor to realize the rotation of the large rotor. Usually, two support tools are used as a group. Since the placement positions of the two support tools cannot ensure that the rollers in the two groups of tools are completely parallel in axis, when the rotor is placed on the two support tools, the rotation axis of the rotor is not parallel to the rollers of the two support tools, resulting in the rotor being unable to rotate normally or having a jamming phenomenon during the rotation process. Long-term operation will cause damage to the rollers of the support tool or wear of the rotation axis of the rotor, greatly increasing the production cost of the enterprise. If the two support tools are fixed together, it will increase the floor area of the support tool and have a greater impact on its handling.

[0003] In summary, how to provide a support device with a self-aligning function to eliminate the need for precise placement is an urgent problem to be solved by those skilled in the art at present. Summary of the Utility Model

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] The core of the present invention is to provide a self-aligning support device for rotary components to reduce the damage to rotary parts during storage by the support tooling.

[0031] Please refer to Figures 1-4 , a self-aligning support device for rotary components, including a support 1, a centering plate 3 and a rotating member 6. A support plate 2 is installed on the support 1, and two support rollers 4 are installed on the centering plate 3. The support rollers 4 are used to place the rotary shaft. That is to say, the rotary shaft of the rotary workpiece to be stored can be placed between the two support rollers 4 to achieve the support of the rotary shaft. The centering plate 3 is located above the support plate 2, and the rotating member 6 is located between the support plate 2 and the centering plate 3, and is used for the rotational relationship of the shapes between the centering plate 3 and the support plate 2.

[0032] It should be noted that the installation method of the support roller 4 in the embodiments of the present utility model is not specifically limited. In some embodiments, the two support rollers 4 can be installed on the centering plate 3 in a manner with a fixed axial distance.

[0033] In other embodiments, the axial distance between the two support rollers 4 can be adjusted. Specifically, a rotating rod perpendicular to the axis of the support roller 4 is installed on the centering plate 3. Two threads with opposite rotation directions are provided on the rotating rod and respectively thread - fit with sliders. The two support rollers 4 are respectively placed on two groups of sliders, thereby realizing the adjustment of the axial distance between the two support rollers 4.

[0034] In still other embodiments of the above - mentioned embodiments, a plurality of corresponding parallel - arranged grooves 9 can be provided on the centering plate 3. By clamping the support roller 4 inside the corresponding groove 9, the support roller 4 is installed on the centering plate 3, and by moving the support roller 4 to different grooves 9, the adjustment of the axial distance between the two support rollers 4 can be realized.

[0035] In addition, the structure of the bracket 1 in the embodiments of the present utility model is not limited, as long as it can complete the support of the workpiece.

[0036] In some embodiments, in order to improve the stability of the bracket 1, the bracket 1 is supported by four support legs, and the four support legs are arranged in a frustum - like structure, thereby increasing the area of the bottom of the bracket 1 and further improving the stability of the bracket 1.

[0037] In other embodiments, in order to improve the stability of the bracket 1, the weight of the bracket 1 itself can be increased, especially the weight of the bottom. Therefore, a counterweight block or the like can be added to the bottom of the bracket 1 to improve the stability of the bracket 1.

[0038] In addition, the specific structure of the support member in the embodiments of the present utility model is not limited. In some embodiments, the support member can be in a columnar structure. By opening a groove 9 at the bottom of the centering plate 3 and placing the support member inside, the rotational relationship between the centering plate 3 and the support plate 2 is realized.

[0039] In other embodiments, in order to improve the smoothness of the rotation of the centering plate 3, the support member can be replaced with a bearing - like workpiece, such as a spherical roller bearing, a tapered roller bearing, a cylindrical roller bearing, etc.

[0040] In use, the support plate 2 is installed on the bracket 1. The centering plate 3 is located above the support plate 2 and is connected thereto by a rotating member 6. The rotating member 6 is used to establish a rotational relationship between the centering plate 3 and the support plate 2. Two support rollers 4 are installed on the centering plate 3. The two support rollers 4 are used to place the rotary shaft. That is to say, placing the rotary shaft of the rotary workpiece to be stored between the two support rollers 4 can achieve the support of the rotary shaft. At the same time, placing two such devices side by side can achieve the storage of rotary workpieces and facilitate the rotation of rotary workpieces to facilitate operations such as installation and debugging. If the two support rollers 4 on the two devices are not collinear, when the rotary workpiece is placed, the centering plate 3 will rotate at a certain angle under its own weight, and finally the axes of the support rollers 4 and the rotary shaft will be parallel, avoiding rotation jamming during the installation and debugging of the rotary workpiece and also avoiding wear and interference to the rotary shaft.

[0041] Please refer to Figure 1 , in some embodiments, to enable the support rollers 4 to rotate freely, two support shafts 8 are further included. The axes of the two support shafts 8 are arranged in parallel. The two support rollers 4 are coaxially and rotatably installed with the two support shafts 8 respectively. That is to say, by rotatably installing the support rollers 4 on the support shafts 8, the installation can be achieved only by placing the support shafts 8 on the centering plate 3, which is convenient and fast, and at the same time ensures that the rotary shaft can rotate freely.

[0042] Please refer to Figure 4 , in some embodiments, two support columns 7 are further included. The two support columns 7 are fixed on the support plate 2. The two ends of the two support shafts 8 are respectively installed on the two support columns 7, and the two support rollers 4 are located between the two support columns 7. The support columns 7 are used to support the support shafts 8 to enable the support rollers 4 to rotate freely.

[0043] It should be noted that in the embodiments of the present invention, the support shaft 8 can be detachably installed on the support column 7. For example, a through hole 10 perpendicular to its axis is opened on the support shaft 8, and a corresponding threaded hole is opened on the support column 7, and the support shaft 8 is fixed to the support column 7 by bolts.

[0044] To enable the device to adapt to rotary shafts of different diameters and ensure the support stability of the rotary shaft, in some embodiments, the axial distance between the two support shafts 8 is adjustable. That is to say, by adjusting the axial distance between the two support shafts 8, when fixing rotary shafts of different diameters, the axis of the rotary shaft and the axes of the two support shafts 8 are arranged in an obtuse triangle, thereby increasing the fixing effect on the rotary shaft and avoiding the situation of the rotary shaft slipping.

[0045] It should be noted that the embodiments of the present invention do not limit the method of adjusting the axis of the support shaft 8.

[0046] In some embodiments, a number of corresponding grooves 9 are provided on two support columns 7. When the support shaft 8 is placed inside the corresponding groove 9, the fixation between the support shaft 8 and the support column 7 is achieved. That is to say, by providing a plurality of juxtaposed grooves 9 on the support column 7 and adjusting the placement of the support shaft 8 in different grooves 9, the adjustment of the spacing between the two support shafts 8 is realized, which is convenient and fast.

[0047] In other embodiments, a rotating rod perpendicular to the axis of the support shaft 8 is installed on the support column 7. Two sections of threads with opposite rotation directions are provided on the rotating rod and are respectively in threaded engagement with sliders. The two support shafts 8 are respectively placed on two groups of sliders, thereby realizing the adjustment of the axial spacing between the two support shafts 8.

[0048] When the method of fixing the support shaft 8 by opening a groove 9 on the support column 7 is adopted, a limiting mechanism can be installed on the support column 7. Specifically, a blocking member is rotatably installed on the support column 7. After the support shaft 8 is placed on the support column 7, the blocking member is rotated and locked between the blocking member and the support column 7, thereby realizing the fixation of the support shaft 8 and avoiding the situation that the support shaft 8 falls off during handling.

[0049] It should be noted that in the embodiments of the present invention, one end of the blocking member is hinged to the support column 7, and the other end is detachably fixedly connected to the support column 7 through a bolt, or a detachable fixed connection is achieved by means of clamping.

[0050] Please refer to Figure 3 , in order to prevent the centering plate 3 from rotating excessively and disengaging from the support plate 2 during handling, in some embodiments, a number of corresponding through holes 10 are provided on the support plate 2 and the centering plate 3. A locking bolt 5 is provided in the through hole 10, and the locking bolt 5 can move freely in the through hole 10. That is to say, by providing a number of corresponding through holes 10 on the support plate 2 and the centering plate 3 and setting a bolt inside the through hole 10 to relatively fix the support plate 2 and the centering plate 3 to prevent them from disengaging.

[0051] It should be noted that in the embodiments of the present invention, the shape of the through hole 10 is not limited. In some embodiments, a circular or linear shape can be adopted, and the relative rotation effect of the centering plate 3 and the support plate 2 can be ensured by increasing the aperture.

[0052] In other embodiments, a number of through holes 10 are all arc-shaped structures centered on the rotation axis of the rotating member 6 and are circumferentially arranged in an array along the rotation axis of the rotating member 6. That is to say, by adopting the through hole 10 with an arc-shaped structure and coaxial with the rotation axis of the rotating member 6, the volume of the bolt is reduced, the cost is lowered, and at the same time, the effective rotation of the centering plate 3 and the support plate 2 can be ensured.

[0053] That is to say, the key point of the embodiment of the present utility model is that: placing the rotating shaft of the rotating workpiece to be stored between two supporting rollers 4 can achieve the support of the rotating shaft. At the same time, placing two such devices side by side can achieve the storage of rotating workpieces, and can facilitate the rotation of the rotating workpieces to facilitate operations such as installation and debugging. If the two supporting rollers 4 on the two devices are not collinear, when the rotating workpiece is placed, the centering plate 3 will rotate at a certain angle under the action of its own weight, and finally the axes between the supporting rollers 4 and the rotating shaft are parallel, avoiding the situation of rotation jamming during the installation and debugging of the rotating workpiece, and at the same time avoiding the wear and interference of the rotating shaft.

[0054] The various embodiments in this specification are described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the various embodiments can be referred to each other.
