Detailed Description of the Embodiments

[0032] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0033] The present utility model provides a rotating device 100, which is used to simulate the motion state of downhole instruments on the working surface before the instruments are lowered into the well, and to test and verify the performance of the instruments.

[0034] Combined with Figure 1 and Figure 2 According to an embodiment of the present utility model, a rotating device 100 for instrument detection includes a fixing frame 10, a main body member 20, and an angle adjusting member 30. The fixing frame 10 can support and fix other components of the rotating device 100, improving the stability of the rotating device 100 during operation; the main body member 20 is disposed on the fixing frame 10 and is configured to clamp the instrument to be detected and drive the instrument to be detected to rotate; the angle adjusting member 30 is respectively connected to the fixing frame 10 and the main body member 20 and is used to adjust the inclination angle of the main body member 20 relative to the working surface.

[0035] Specifically, the instrument to be detected can be installed on the main body member 20. The main body member 20 can clamp and drive the instrument to be detected to rotate. In addition, the inclination angle of the main body member 20 relative to the working surface can be adjusted by the angle adjusting member 30. Thus, the instrument to be detected can have different inclination angles relative to the working surface, facilitating the driving of the instrument to be detected to rotate at different inclination angles. Exemplarily, the rotating device 100 can be connected to the testing device of the instrument. When the instrument rotates at different inclination angles, the performance of the instrument can be monitored through the testing device, thereby improving the accuracy of the detection result of the instrument.

[0036] It should be noted that the inclination angle of the main body member 20 relative to the working surface corresponds to the included angle between the rotation axis of the instrument and the working surface. It can be understood that during the drilling process, the drilling tool needs to work at a certain inclination angle according to different geological conditions. Correspondingly, the instrument also needs to rotate at the corresponding inclination angle. Therefore, it is necessary to detect the performance of the instrument rotating at different angles. By setting the angle adjusting member 30, the inclination angle of the instrument clamped on the main body member 20 relative to the working surface can be adjusted, thereby facilitating the rotating device 100 to drive the instrument to rotate at different angles.

[0037] According to an embodiment of the present utility model, the rotating device 100 for instrument detection adjusts the inclination angle of the main body member 20 relative to the working surface by setting the angle adjusting member 30, facilitating the main body member 20 to drive the instrument to rotate at different angles, facilitating the detection of the performance of the instrument when rotating at the corresponding angle, and improving the convenience and accuracy of the performance monitoring of the instrument.

[0038] Among them, the angle adjusting member 30 is used to adjust the inclination angle of the main body member 20 relative to the working surface. Exemplarily, the working surface can be a horizontal plane. By adjusting the inclination angle of the instrument relative to the horizontal plane, it is convenient for the main body member 20 to drive the instrument to rotate at the corresponding angle to simulate the working state of the instrument under the corresponding working conditions. Of course, the working surface is not limited to the horizontal plane and can also be a vertical plane, an inclined plane, etc. Exemplarily, the fixing frame 10 can be fixed on the vertical plane or the inclined plane to simulate the actual working scenario.

[0039] In addition, the main body 20 drives the instrument to be detected to rotate, and can drive the instrument to rotate at different speeds to simulate the working states under different working conditions during the drilling process.

[0040] By setting the angle adjusting member 30, the inclination angle of the main body 20 relative to the working surface is adjusted. Among them, the main body 20 is rotatably connected to the fixing frame 10. Exemplarily, the main body 20 may be provided with a fixed shaft 27, and the fixed shaft 27 is rotatably connected to the fixing frame 10. That is to say, the main body 20 can rotate relative to the fixing frame 10 around the fixed shaft 27, and the main body can be unlocked and locked to the fixing frame 10 through the angle adjusting member 30; or, the angle adjusting member 30 is rotatably connected to the fixing frame 10, and the angle adjusting member 30 is fixedly connected to the main body 20. Exemplarily, the angle adjusting member 30 can be rotated to adjust the angle between the angle adjusting member 30 and the fixing frame 10, thereby realizing the adjustment of the inclination angle between the main body 20 and the fixing frame 10.

[0041] Combined with Figure 2 In some embodiments of the present invention, the main body 20 is rotatably connected to the fixing frame 10, and the main body 20 can be supported by the fixing frame 10 to improve the structural stability of the main body 20. The angle adjusting member 30 is used to lock and unlock the main body 20. When the angle adjusting member 30 locks the main body 20, the main body 20 and the fixing frame 10 are relatively stationary, and when the angle adjusting member 30 unlocks the main body 20, the main body 20 can rotate relative to the fixing frame 10. Specifically, when it is necessary to adjust the inclination angle of the main body 20 relative to the working surface, the main body 20 can be unlocked through the angle adjusting member 30. At this time, the main body 20 can rotate relative to the fixing frame 10, the main body 20 can be rotated and adjusted to a predetermined angle, and then the main body 20 is locked through the angle adjusting member 30, so as to facilitate the rotating device 100 to drive the instrument to rotate at a predetermined angle. By setting the angle adjusting member 30 to lock and unlock the main body 20, the angle adjustment of the main body 20 is made more convenient.

[0042] Exemplarily, a pedestal bearing can be provided on the fixing frame 10, and a fixed shaft 27 can be provided on the main body. The fixed shaft 27 is arranged in the pedestal bearing, and the main body 20 can rotate around the fixed shaft 27. By setting the pedestal bearing, the friction force of the main body 20 rotating relative to the fixing frame 10 is reduced, which is convenient for adjusting the inclination angle of the main body 20 relative to the working surface.

[0043] Among them, the predetermined angle corresponds to the included angle between the rotation axis of the instrument clamped by the main body 20 and the working surface. The predetermined angle can be between 0-90°, and exemplarily, it can be 0°, 30°, 45°, 60° and 90°, etc.

[0044] Combined with Figure 1 and Figure 2, in some embodiments of the present utility model, the angle adjusting member 30 includes a limiting plate 31 and a positioning portion 32. The limiting plate 31 is connected to the main body member 20 and is provided with a plurality of positioning holes 311 arranged at intervals. The plurality of positioning holes 311 are distributed around the rotation center axis of the main body member 20. The positioning portion 32 is provided on the fixing bracket 10 and can be disengaged from and inserted into the positioning holes 311. Specifically, when the positioning portion 32 is disposed in different positioning holes 311, the main body member 20 can have different inclination angles relative to the working surface. When the positioning portion 32 is disengaged from the positioning hole 311, the angle adjusting member 30 can unlock the main body member 20, and the main body member 20 can rotate relative to the fixing bracket 10 to facilitate adjusting the inclination angle of the main body member 20 relative to the working surface. When the positioning portion 32 is inserted into the positioning hole 311, the main body member 20 can be locked to the fixing bracket 10. By providing the limiting plate 31 and the positioning portion 32, it is convenient to adjust the inclination angle of the main body member 20 relative to the working surface. Among them, the limiting plate 31 can be an annular plate.

[0045] Exemplarily, the positioning portion 32 may include a convex block and a handle pin. The convex block can be fixed to the fixing bracket 10 by screws. The handle pin passes through the convex block and is slidably connected to the convex block. The convex block can position the handle pin. When the handle pin is disengaged from the positioning hole 311, the main body member 20 can be unlocked. When the handle pin is inserted into the positioning hole 311, the main body member 20 can be locked.

[0046] Optionally, the limiting plate 31 can be fixed to the main body member 20 through a fixing pad. That is to say, a fixing pad is provided between the limiting plate 31 and the main body member 20, and the fixing pad can reduce the wear on the main body member 20.

When the rotating device 100 is working, the housing 21 is fixed to the fixing bracket 10, and the rotating portion 22 rotates relative to the housing 21. The housing 21 can protect the rotating portion 22 and facilitate improving the stability of the rotating portion 22 during rotation.

[0048] Among them, the installation cavity 221 is configured to have an adjustable inner diameter. It should be noted that the inner diameter of the installation cavity 221 corresponds to the outer diameter of the instrument to be clamped, so that the rotating part 22 can clamp instruments with different outer diameters, improving the versatility of the rotating device 100. The adjustable inner diameter of the installation cavity 221 can be achieved in different ways. Exemplarily, structures such as pins and screws can be provided in the installation cavity 221, and the pins, screws, etc. can be driven to move by setting an adjustment part outside the installation cavity 221, so as to clamp instruments with different outer diameters; for another example, an adjustable opening can be provided on the peripheral wall of the installation cavity 221, and instruments with different outer diameters can be clamped by adjusting the size of the opening.

In addition, the first bearing 2231 can float relative to the bushing 222, and the relative position of the second bearing 2232 is fixed relative to the bushing 222. By setting the first bearing 2231 to a structure that can float relative to the bushing 222, the internal stress during the operation of the rotating part 22 can be released, the internal stress caused by dimensional deviation can be reduced, and the working stability of the rotating part 22 can be improved.
