[0041] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] In order to facilitate understanding of the support device and wind turbine gearbox testing equipment provided by the utility model, their application background is first introduced. As a core component in a wind turbine generator set, a wind turbine gearbox often needs to be subjected to an inclined cleaning test, that is, the gearbox is placed on a support device for dynamic or static cleaning tests.

[0043] In the related art, the supporting device generally adopts a welded bracket with a specific tilt angle, so that the gear box is tilted after being fixed to the supporting device. However, this welded bracket can only be applied to a specific model of gear box and has poor applicability.

[0044] Based on the above problems, the utility model provides a supporting device and a wind power gearbox testing device, which can support gearboxes of different models and have good applicability.

[0045] Combine the following Figure 1-Figure 5 The utility model describes a supporting device and a wind power gearbox testing device.

[0046] Reference Figure 1 and Figure 2 A supporting device includes a first support 10 and a second support 20; wherein the first support 10 includes a first base 100 and a first supporting portion 101, the first supporting portion 101 is suitable for supporting the high-speed end of a gear box and is connected to the first base 100 through a lifting and adjusting mechanism 11, the lifting and adjusting mechanism 11 is used to adjust the height of the first supporting portion 101 relative to the first base 100; the second support 20 is spaced apart from the first support 10, and the distance between the second support 20 and the first support 10 can be adjusted; the second support 20 is provided with a supporting groove 200 with an opening facing upward, the width of the supporting groove 200 gradually expands from the bottom to the top opening, and is suitable for supporting the low-speed end of the gear box.

[0047] In a specific application scenario, when conducting a gearbox tilt cleaning test, the low-speed end of the gearbox is supported in the support groove 200 of the second support 20. The support groove 200 can better adapt to the arc-shaped outer contour of the low-speed end, ensuring the stability of the gearbox on the support device. Then, the high-speed end of the gearbox is supported on the first support part 101 of the first support 10. By adjusting the height of the first support part 101, the gearbox tilt angle can be adjusted so that its tilt angle meets the test requirements.

[0048] Since the width of the support groove 200 gradually expands from the bottom to the top of the opening direction, the support groove 200 can stably support the low-speed end of gear boxes of different models. By adjusting the distance between the first support 10 and the second support 20, the support device can adapt to the length of gear boxes of different models. By adjusting the height of the first support part 101, the inclination angle of the gear box can be adjusted. When performing an inclined cleaning test on gear boxes of different models, it is only necessary to adaptively adjust the distance between the first support 10 and the second support 20 and the height of the first support part 101 to meet the support requirements of gear boxes of different models. Then, the gear box can be placed on the support device to stably support the gear box at a preset inclination angle. Compared with the related art, the above-mentioned support device has a simpler structure, the gear box is more convenient to install, and can be applicable to the support of gear boxes of different models, and has good applicability.

[0049] The various components in the supporting device will be described in detail below with reference to the accompanying drawings.

[0050] Reference Figure 1 and Figure 2 The first base 100 serves as the bottom supporting part of the first support 10 and can provide an installation basis for other components on the first support 10. Specifically, the first base 100 is a plate-like structure as a whole, and can be made of metal materials such as steel and cast iron to ensure its own supporting strength. The plate-like first base 100 can have a large contact area with the ground or other supporting components, thereby improving its own stability and further ensuring the stability of the first support 10.

[0051] The first support part 101 is connected to the plate surface of the first base 100 through the lifting and adjusting mechanism 11. The first support part 101 is plate-shaped and made of metal materials such as steel and cast iron. Its model and specifications can be configured according to actual needs. It is only necessary to ensure that the first support part 101 itself can meet the required support strength.

[0052] In one embodiment, the first support portion 101 is provided with one, that is, the first support portion 101 is formed by a metal plate, and the support area formed by it can meet the support requirements of the high-speed end of various different types of gearboxes. However, with this solution, the weight of the first support portion 101 is heavy, and there will be certain inconveniences in adjustment.

[0053] Therefore, in another embodiment, more than two first support parts 101 are arranged at intervals, that is, the support area formed by multiple first support parts 101 can meet the support requirements of the high-speed ends of various different types of gearboxes. In this way, the weight of a single first support part 101 is smaller and adjustment is more convenient.

[0054] In this embodiment, two first support parts 101 are arranged at intervals along the length direction of the first base 100. The two first support parts 101 are both connected to the plate surface of the first base 100 through the lifting adjustment mechanism 11.

[0055] In one embodiment of the present invention, referring to Figure 3 and Figure 4 The first adjustment mechanism includes a first adjustment part 110, a second adjustment part 111 and a first positioning member 112; wherein the first adjustment part 110 is fixedly connected to the first base 100, the second adjustment part 111 is fixedly connected to the first support part 101, and in the lifting direction of the first support part 101, the first adjustment part 110 and the second adjustment part 111 are slidably matched; the first positioning member 112 is used to locate the relative positions of the first adjustment part 110 and the second adjustment part 111.

[0056] In practical applications, the first adjustment portion 110 and the second adjustment portion 111 can be made to slide relative to each other to change the height of the first support portion 101. After adjusting to a preset height, the relative positions of the first adjustment portion 110 and the second adjustment portion 111 are positioned by the first positioning member 112, and the first support portion 101 is positioned at a preset height, thereby completing the adjustment of the height of the first support portion 101.

[0057] In one embodiment of the utility model, one of the first adjustment part 110 and the second adjustment part 111 is provided with a plurality of first positioning holes 113 arranged along its length direction, and the other is provided with a second positioning hole 114. When the first adjustment part 110 and the second adjustment part 111 slide relative to each other, the second positioning hole 114 can correspond to different first positioning holes 113, and the first positioning member 112 is used to pass through the first positioning hole 113 and the second positioning hole 114 in sequence, thereby realizing the positioning of the first adjustment part 110 and the second adjustment part 111.

[0058] Specifically, the first adjustment part 110 can be set as a rod-shaped structure or a plate-shaped structure, and is made of metal materials such as steel and cast iron to ensure its own support strength. One end of the first adjustment part 110 is fixedly connected to the first base 100, for example, it can be connected by welding or by connecting members such as bolts, and the other end extends in a direction perpendicular to the plate surface of the first base 100; the first positioning hole 113 is opened on the first adjustment part 110, for example, several commonly used heights can be selected and the first positioning hole 113 can be set at the corresponding position to achieve support for several specific models of gearboxes and adjustment of several specific angles.

[0059] The second adjustment part 111 can also be set as a rod-shaped or plate-shaped structure, which is made of metal materials such as steel and cast iron to ensure its own supporting strength. One end of the second adjustment part 111 is fixedly connected to the first support part 101, for example, it can be connected by connecting components such as welding or bolts. The second positioning hole 114 is opened on the second adjustment part 111. During the sliding process of the second adjustment part 111 relative to the first adjustment part 110, the second positioning hole 114 can correspond to different first positioning holes 113.

[0060] Specifically, the first positioning member 112 is configured as a rod-shaped structure, for example, a bolt or a positioning pin can be used. When the second positioning hole 114 corresponds to the first positioning hole 113 at a specific position, the rod-shaped first positioning member 112 is passed through the second positioning hole 114 and inserted into the first positioning hole 113, thereby realizing the positioning of the first adjustment part 110 and the second adjustment part 111.

[0061] Since the gearbox is heavy, in order to ensure the structural strength and positioning stability, more than two first positioning holes 113 can be arranged side by side at each height, and correspondingly, more than two second positioning holes 114 are arranged side by side. After adjusting to a predetermined height, more than two first positioning members 112 are used for positioning, thereby ensuring the structural strength and positioning stability.

[0062] In addition, when the first adjustment part 110 and the second adjustment part 111 are both configured as rod-shaped structures, the two can be matched in a plug-in manner to ensure the smoothness of height adjustment and the stability of the structure. When the first adjustment part 110 is configured as a plate-shaped structure, a pair of second adjustment parts 111 are arranged at intervals, and the first adjustment part 110 is arranged between the pair of second adjustment parts 111, so as to ensure the structural strength and positioning stability. In this embodiment, the first adjustment part 110 and the second adjustment part 111 are both configured as plate-shaped structures, a pair of second adjustment parts 111 are arranged, and the first adjustment part 110 is arranged between the pair of second adjustment parts 111.

[0063] It is understandable that when the gearbox is installed on the support device, there will inevitably be an angle between the support leg on the high-speed end of the gearbox and the plate-shaped first support portion 101. This angle generally does not exceed 10 degrees. The existence of the angle will make it impossible for the support leg and the first support portion 101 to fit together and present a line contact, resulting in a certain impact on the stability of the support.

[0064] In order to solve the above problems, in one embodiment of the utility model, the support device further includes an adjustment structure for adjusting the angle of the first support portion 101 relative to the first base 100. Through the adjustment structure, the angle of the first support portion 101 can be adjusted so that the first support portion 101 and the support leg of the high-speed end of the gear box can achieve surface contact. Compared with line contact, surface contact has a larger contact area, thereby improving the stability of the gear box on the support device.

[0065] Specifically, one of the first positioning hole 113 and the second positioning hole 114 is set as an arc hole, and the first positioning member 112 slides with the arc hole, so that the first positioning member 112 and the arc-shaped first positioning hole 113 or the second positioning hole 114 form the above-mentioned adjustment structure. In practical applications, after the first positioning member 112 passes through the first positioning hole 113 and the second positioning hole 114 in sequence, not only can the height of the first support portion 101 be positioned, but also because the first positioning member 112 slides with the arc hole, during the relative sliding of the first positioning member 112 and the arc hole, the first support portion 101 can be flipped to a certain angle, so that the first support portion 101 and the support leg of the high-speed end of the gear box can achieve surface contact, which is beneficial to improve the stability of the support. In addition, the arc hole can also play the role of angle limiting.

[0066] More specifically, the second positioning hole 114 is configured as an arc-shaped hole, and the curvature of the arc-shaped hole can be designed according to actual needs, and is not specifically limited in the embodiment of the utility model.

[0067] It is understandable that the adjustment structure includes but is not limited to the structures or forms listed above, and other structures or forms of adjustment structures are also applicable as long as the angle of the first support part 101 can be adjusted.

[0068] It can be understood that the lifting and adjusting mechanism 11 includes but is not limited to the structures or forms listed above, and other structures or forms of lifting and adjusting mechanisms 11 are also applicable. For example, a hydraulic cylinder, an electric push rod or other linear driving element is used as the lifting and adjusting mechanism 11 to push the first support part 101 up and down, thereby achieving stepless height adjustment.

[0069] It is understandable that the various components in the first support 10, such as the first base 100, the first support portion 101, etc., include but are not limited to the structures, shapes and materials listed above, and can be flexibly configured according to actual needs and application scenarios.

[0070] It is understandable that reinforcing components such as reinforcing plates and reinforcing ribs may be provided between the various components of the first support 10 to improve the structural stability of the first support 10 and ensure its load-bearing performance.

[0071] The specific structure of the second support 20 will be described in detail below with reference to the accompanying drawings.

[0072] Reference Figure 1 and Figure 2 The second support 20 includes a second base 201 and a second support portion 202; wherein, the second base 201, as the bottom support portion of the second support 20, can provide a mounting base for other components on the second support 20. Specifically, the second base 201 is a plate-shaped structure as a whole, and can be made of metal materials such as steel and cast iron to ensure its own support strength. The plate-shaped second base 201 can have a large contact area with the ground or other supporting components, which is conducive to improving its own stability, thereby ensuring the stability of the second support 20. The second support portion 202 is fixedly connected to the second base 201, for example, it can be connected by welding or by connecting members such as bolts, and the support groove 200 is provided on the second support portion 202.

[0073] The support groove 200 is V-shaped, and its two side walls are used to support the opposite sides of the low-speed end of the gear box respectively. When the diameter of the low-speed end of the gear box changes, its support position in the support groove 200 will change, but it will still be restricted in the support groove 200. Specifically, a V-shaped groove can be opened on the second support part 202 to form the support groove 200, or a V-shaped profile can be directly used as the second support part 202. In this embodiment, the second support part 202 uses a V-shaped profile to ensure the strength and support performance of the second support part 202 itself.

[0074] Specifically, the second support 20 further includes a reinforcing rib plate 203 , which is fixedly connected to the second base 201 and the second support portion 202 to play a reinforcing role and ensure the structural strength of the second support 20 .

[0075] The low-speed end of the gearbox can be supported by the first support 10, and the high-speed end of the gearbox can be supported by the second support 20. In addition, by changing the distance between the first support 10 and the second support 20 and the height of the second support portion 202 on the second support 20, it is possible to support gearboxes of different models.

[0076] Reference Figure 1 and Figure 5 In order to further improve the stability of the support and avoid the problem of the first support 10 and the second support 20 tipping over during use, an embodiment of the utility model further includes a connecting member 30 for connecting the first support 10 and the second support 20.

[0077] Specifically, the connecting member 30 includes a first connecting portion 300, a second connecting portion 301 and a second positioning member 302, wherein the first connecting portion 300 is fixedly connected to the first support 10, the second connecting portion 301 is fixedly connected to the second support 20, and the first connecting portion 300 and the second connecting portion 301 are slidably matched, so that the first support 10 and the second support 20 can be close to or away from each other; the second positioning member 302 is used to locate the relative position of the first connecting portion 300 and the second connecting portion 301. Through the connecting member 30, the first support 10 and the second support 20 can be connected as a whole under the premise of adjusting the distance between the first support 10 and the second support 20, which effectively avoids the problem of the first support 10 and the second support 20 tipping over.

[0078] In one embodiment of the utility model, the first connecting part 300 is a long rod-shaped structure, which can be specifically made of steel or cast iron, one end of which is fixedly connected to the first support 10, specifically, it can be fixedly connected to the first base 100 of the first support 10, and the other end thereof extends toward the direction of the second support 20; the second connecting part 301 is a long rod-shaped structure, which can be specifically made of steel or cast iron, one end of which is fixedly connected to the second support 20, specifically, it can be fixedly connected to the second base 201 of the second support 20, and the other end thereof extends toward the direction of the first support 10, and there are staggered and overlapping parts between the first connecting part 300 and the second connecting part 301.

[0079] One of the first connection part 300 and the second connection part 301 is provided with a plurality of first holes 303 arranged along its length direction, and the other is provided with a second hole; during the relative sliding process between the second connection part 301 and the first connection part 300, the second hole can correspond to different first holes 303, and the second positioning member 302 is adapted to pass through the first hole 303 and the second hole in sequence to achieve the positioning of the first connection part 300 and the second connection part 301. Specifically, the second positioning member 302 can be a bolt, a positioning pin, etc.

[0080] In an embodiment of the present invention, the first connection part 300 is configured as a tubular structure, and the first hole 303 is disposed on the first connection part 300 ; the second connection part 301 is plug-fitted with the first connection part 300 , and the second hole is disposed on the second connection part 301 .

[0081] It is understandable that the connecting member 30 includes but is not limited to the structures or forms listed above, and connecting members 30 of other structures or forms are equally applicable, as long as the first support 10 and the second support 20 can be connected as a whole under the premise of achieving the distance adjustment between the first support 10 and the second support 20.

When performing tilt cleaning tests on gearboxes of different models, it is only necessary to adaptively adjust the distance between the first support 10 and the second support 20 and the height of the first support part 101 to meet the support requirements of gearboxes of different models, and then place the gearbox on the support device to stably support the gearbox at a preset inclination angle.
