[0002] In the industrial field, a rotary equipment at least includes an equipment base and an equipment rotating body. The equipment base is firmly connected to a base by means of fasteners. When the equipment is working, the equipment rotating body makes a rotational movement around a fixed rotation axis.

[0003] When the rotary equipment comes off the production line, no matter when and where it operates, the spatial position of its fixed rotation axis relative to the whole equipment always remains fixed. Therefore, when the rotary equipment is fixedly installed on the base, the spatial position of this fixed rotation axis is fixed accordingly. During the operation of the equipment, the equipment rotating body rotates around the fixed axis, and the plane perpendicular to this fixed axis is the rotary plane. Given that the spatial position of the fixed rotation axis is fixed, the spatial position of the rotary plane also remains fixed.

[0004] To ensure the working accuracy of the rotary equipment, the levelness of the rotary plane needs to meet specific technical index requirements. Therefore, it is necessary to measure the levelness of the rotary plane of the rotary equipment to determine whether it meets the technical indexes.

[0048] The following further describes in detail the specific embodiments of the present invention with reference to the drawings. These embodiments are only used to illustrate the present invention and are not intended to limit the present invention.

[0049] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0050] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] In addition, in the description of the present invention, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0052] According to the first aspect of the present application, referring to Figures 1 to 4 , first, a repair method for a rotary device is provided, including the following steps:

[0053] S1. Place a measurement module on the detection platform, rotate the rotary device to different angular positions multiple times, and measure the flatness of the detection plane of the rotary device at different angular positions through the measurement module. Define a plurality of detection plane flatnesses as a detection plane flatness data set.

[0054] It should be noted that the initial position of the rotary device is the 0° position. After the rotary device rotates one week, the measurement stops, that is, when the rotary device rotates to the 360° position, the measurement stops. The angle of each rotation of the rotary device is the same. In this embodiment, the rotary device rotates 30° each time.

[0055] In an implementable manner, in step S1, adjust the position of the measurement module on the detection platform, repeat step S1 to respectively obtain a first data set, a second data set, and a third data set. Obtain an average data set based on the first data set, the second data set, and the third data set, and use the average data set as the detection plane flatness data set to reduce the measurement error and improve the data detection accuracy.

[0056] Specifically, in this embodiment, the first data group includes a1, b1, c1, d1... l1, a total of 12 data. The second data group includes a2, b2, c2, d2... l2, and the third data group includes a3, b3, c3, d3... l3. The average data group includes a, b, c, d... l.

[0057] a = (a1 + a2 + a3) / 3;

[0058] b = (b1 + b2 + b3) / 3;

[0059] ...

[0060] l = (l1 + l2 + l3) / 3.

[0061] S2. Determine the horizontal degree of the slewing plane based on the horizontal degree data group of the detection plane;

[0062] In an implementable manner, obtain the average value between the horizontal degree of each detection plane and the corresponding relative angular horizontal degree respectively, and use the maximum value among the multiple average values as the horizontal degree of the slewing plane.

[0063] Specifically, as Figure 2 shown, two measurement positions on the upper surface of the slewing equipment that are on the same straight line are defined as relative angular positions. For example, a and g are relative angular positions to each other, b and h are relative angular positions to each other, etc.

[0064] Use the average value of the horizontal degree a of the detection plane at the corresponding angular position and its relative angular horizontal degree g as the first horizontal degree A of the slewing plane. That is, A = (a - g) / 2;

[0065] Use the average value of the horizontal degree b of the detection plane at the corresponding angular position and its relative angular horizontal degree h as the second horizontal degree B of the slewing plane. That is, B = (b - h) / 2;

[0066] Use the average value of the horizontal degree c of the detection plane at the corresponding angular position and its relative angular horizontal degree i as the third horizontal degree C of the slewing plane. That is, C = (c - i) / 2;

[0067] ...

[0068] Use the average value of the horizontal degree f of the detection plane at the corresponding angular position and its relative angular horizontal degree l as the sixth horizontal degree F of the slewing plane. That is, F = (f - l) / 2.

[0069] Select the maximum value among the multiple average values as the horizontal degree σ of the slewing plane, that is, σ = MAX{A, B, C... F}.

[0070] It should be noted that, as Figure 3As shown in the figure, the levelness of the detection plane at an angular position is defined as b, that is, b is the angle between the detection plane and the earth's horizontal plane. The levelness of the detection plane at the relative angle of this angular position is defined as b', that is, b' is the angle between the detection plane and the earth's horizontal plane. a is the levelness of the rotating plane at this angular position, that is, a is the angle between the rotating plane and the earth's horizontal plane.

[0071] As Figure 4 shown in the figure, according to the fact that the angle between the detection plane and the rotating plane is fixed, that is, b - a = a + b', so, a = (b - b') / 2.

[0072] Therefore, by obtaining the levelness of the detection plane at an angular position and the levelness of the detection plane at its relative angular position, the levelness of the rotating plane at this position can be determined.

[0073] S3. Compare the levelness of the rotating plane σ with the predetermined levelness, and determine the grinding amount and grinding position according to the comparison result;

[0074] It should be noted that the predetermined levelness is the levelness technical index δ.

[0075] Specifically, when the levelness of the rotating plane σ is less than or equal to the levelness technical index δ, grinding is not required, indicating that the levelness of the rotating plane meets the requirements.

[0076] When the levelness of the rotating plane σ is greater than the levelness technical index δ, grinding is required.

[0077] In an implementable manner, in step S3, it at least further includes the following content:

[0078] S31. Determine the grinding amount:

[0082] T is the grinding amount.

[0083] S32. Determine the grinding position:

[0084] When selecting the maximum value among multiple average values as the levelness of the rotating plane σ, the measurement angular position X corresponding to the maximum value is the grinding position, such as the 30-degree position.

[0085] S4. Repair the rotating equipment based on the grinding amount and the grinding position.

[0086] In an implementable manner, in step S4, it at least further includes the following content:

[0091] S44. Lift the rotating equipment onto the hull base and secure it.

[0092] S45, repeat steps S1 to S2 to re-measure the horizontality of the rotating plane.

[0093] In another practicable manner, when the rotation plane is a superimposed rotation plane, that is, the rotation device includes a first rotation device and a second rotation device;

[0094] The position of the first rotating device is fixed to the initial position, i.e., the 0° position, and steps S1 to S2 are repeated to rotate the second rotating device to different angles for multiple times, and the horizontality of the second rotating device at different angles is respectively obtained as a detection plane horizontality data group; and the rotation plane horizontality σ(0°) is determined according to the detection plane horizontality data group;

[0095] The position of the first rotating device is fixed at the 30° position, steps S1 to S2 are repeated, the second rotating device is rotated to different angles for multiple times, and the horizontality of the second rotating device at different angles is respectively obtained as a detection plane horizontality data group; and the rotation plane horizontality σ(30°) is determined according to the detection plane horizontality data group;

[0096] After the first rotating device is rotated by a predetermined angle, steps S1 to S2 are repeated to respectively obtain a plurality of rotating plane horizontalities σ(X°); until the first rotating device is rotated to the initial position again.

[0097] In an practicable manner, in step S3, the horizontality σ(X°) of the rotary plane is compared with the predetermined horizontality δ, and the grinding amount and grinding position are determined according to the comparison result.

[0098] Specifically, when the horizontality of the rotating plane is greater than the predetermined horizontality:

[0099] Get the horizontality σ of the rotation plane of the first rotation device 1 and the horizontality of the rotation plane of the second rotary device σ 2; According to the formula t = D × arctan (σ 2 -σ 1 ) determines the grinding amount; wherein D is the diameter of the mounting platform on the first rotary device for mounting the second rotary device;

[0100] The grinding object is a mounting platform on the first rotary device for mounting the second rotary device;

[0101] When determining the horizontality of the rotary plane, the measured angle position corresponding to the maximum value in the average value is selected as the grinding position X.

[0102] In an practicable manner, in step S4, at least the following contents are also included:

[0103] S41, lifting the second rotary device, and marking on the installation platform of the first rotary device according to the grinding position X and the grinding amount t.

[0104] S42. Use an angle grinder to grind the upper surface of the installation platform to the marked line at the grinding position.

[0105] It should be noted that when grinding to the vicinity of the scribe line, grinding is performed on both sides of the scribe line, and the grinding amount is less than t.

[0110] Wipe the detection platform and the measuring surface of the measuring module with alcohol respectively. After they are dry, place the measuring module on the detection platform to prevent stains on the detection platform or the measuring module from affecting the measurement results.

[0111] In one practicable manner, before step S1, the accuracy of the measurement module is determined:

[0112] The measuring module is placed at a predetermined position to obtain a first measurement value, and the measuring module is rotated 180 degrees to obtain a second measurement value. When the difference between the first measurement value and the second measurement value is less than or equal to 10", it indicates that the accuracy of the measuring module meets the requirements and can be used normally.

[0113] It should be noted that before step S1, it is also necessary to obtain the temperature and humidity during detection. When the temperature is greater than 30 degrees or the humidity is greater than 80%, the detection conditions are not met, so as to avoid the influence of objective factors such as foreign objects, rain, temperature and humidity, and ensure the accuracy of subsequent measurement data.

[0114] According to the second aspect of the present application, there is also provided a repair system for a rotary device, which is used to implement the repair method of the rotary device provided in the first aspect. It includes:

[0115] A measuring unit, placed on the detection platform, is used to obtain the levelness and output it;

[0119] It should be noted that the system further includes a storage unit, which can store measurement data, calculation results, etc.; and perform data playback through the display and control unit. The data playback at least includes the time, temperature, humidity, levelness and calculation results of at least one measurement.

[0120] To sum up, the present application directly measures the levelness of the detection plane, reduces the measurement difficulty, and improves the measurement accuracy. By calculating the levelness of the rotary plane according to the levelness of the detection plane, it can effectively solve the problem that the levelness of the rotary plane cannot be directly measured.
