Fig. 1 illustrates a schematic structural diagram of a rotor support according to an embodiment of the present invention. As shown in fig. 1, the rotor holder includes: the device comprises a support frame 1, a first support mechanism 2, a first rotating mechanism 3, a second support mechanism 4 and a second rotating mechanism 5; the first supporting mechanism 2 is connected to a first inclined plane of the supporting frame 1, a first end of the first supporting mechanism 2 extends out of the first inclined plane, the second supporting mechanism 4 is connected to a second inclined plane of the supporting frame 1, a first end of the second supporting mechanism 4 extends out of the second inclined plane, and the distance between the first end of the first supporting mechanism 2 and the first end of the second supporting mechanism 4 is smaller than the distance between a second end of the first supporting mechanism 2 and a second end of the second supporting mechanism 4; the first rotating mechanism 3 is connected with the first end of the first supporting mechanism 2, the second rotating mechanism 5 is connected with the first end of the second supporting mechanism 4, the central line of the first rotating mechanism 3 is parallel to the central line of the second rotating mechanism 5, the first supporting mechanism 2 can adjust the height of the first rotating mechanism 3, and the second supporting mechanism 4 can adjust the height of the second rotating mechanism 5.

The embodiment of the utility model provides an in, because first supporting mechanism 2 is fixed on first inclined plane, second supporting mechanism 4 is fixed on the second inclined plane, and the top of support frame 1 is all stretched out to the first end of first supporting mechanism 2 and the first end of second supporting mechanism 4, consequently can form the support to the one end of rotor through the first rotary mechanism 3 of being connected with first supporting mechanism 2 and the second rotary mechanism 5 of being connected with second supporting mechanism 4. Because one end of the rotor is supported on the first rotating mechanism 3 and the second rotating mechanism 5, and the central line of the first rotating mechanism 3 is parallel to the central line of the second rotating mechanism 5, when the rotor rotates, the first rotating mechanism 3 and the second rotating mechanism 5 can be driven to synchronously rotate, so that the relative friction between the rotor and the rotor support is avoided, and the rotor is prevented from being damaged. In addition, the first supporting mechanism 2 can adjust the height of the first rotating mechanism 3 along the first inclined plane, and the second supporting mechanism 4 can adjust the height of the second rotating mechanism 5 along the second inclined plane, so that the height adjustment of the first rotating mechanism 3 and the second rotating mechanism 5 can be realized, meanwhile, the adjustment of the distance between the first rotating mechanism 3 and the second rotating mechanism 5 can be realized, the rotor support can be further suitable for rotors with different diameters, and the applicability of the rotor support is increased. In addition, when the two ends of the rotor are supported, at least two rotor supports are often needed to support the rotor through at least four rotating mechanisms, and the height of each rotating mechanism is adjustable, so that the at least four rotating mechanisms can be ensured to be positioned on the same horizontal plane to support the rotor more stably.

Wherein, support frame 1 can be trapezoidal frame 11, also can be the triangle-shaped frame, of course, support frame 1 still can be the frame of other shapes, the embodiment of the utility model provides a do not limit to this.

When the supporting frame 1 is a trapezoid frame 11, in order to support the rotor, the first supporting mechanism 2 and the second supporting mechanism 4 may be two oblique sides of a virtual trapezoid, that is, the first supporting mechanism 2 and the second supporting mechanism 4 do not intersect. In this way, when the height of the first rotating mechanism 3 is adjusted by the first supporting mechanism 2 and the height of the second rotating mechanism 5 is adjusted by the second supporting mechanism 4, the distance between the first rotating mechanism 3 and the second rotating mechanism 5 can be reduced along with the increase of the heights, so that the support of the rotor with a smaller size is realized, and the distance between the first rotating mechanism 3 and the second rotating mechanism 5 can be increased along with the decrease of the heights, so that the support of the rotor with a larger size is realized.

When the support frame 1 is a triangular frame, in order to support the rotor, the first support mechanism 2 and the second support mechanism 4 need to intersect with each other, so as to ensure that a certain distance exists between the first end of the first support mechanism 2 and the first end of the second support mechanism 4. In this way, when the height of the first rotating mechanism 3 is adjusted by the first supporting mechanism 2 and the height of the second rotating mechanism 5 is adjusted by the second supporting mechanism 4, the distance between the first rotating mechanism 3 and the second rotating mechanism 5 can be increased along with the increase of the heights, so that the rotor with a larger size can be supported, and the distance between the first rotating mechanism 3 and the second rotating mechanism 5 can be decreased along with the decrease of the heights, so that the rotor with a smaller size can be supported.

And because the fixed cylinder 21 is fixedly connected with the first inclined plane, when the connecting rod 22 is rotated relative to the fixed cylinder 21, the connecting rod 22 can generate displacement along the axial direction of the fixed cylinder 21, and further the height of the first end of the connecting rod 22 can be adjusted.

In practical implementation, the groove at one end of the connecting rod 22 may have an internal thread, and the end of the first rotating mechanism 3 may have an external thread, so that the first rotating mechanism 3 is rotated in the groove of the connecting rod 22 along the circumferential direction of the connecting rod 22 by means of a threaded connection. Therefore, the direction of the first rotating mechanism 3 can be adjusted according to actual conditions so as to adjust the first rotating mechanism 3 to an actually required angle position, thereby ensuring that the central line of the first rotating mechanism 3 is parallel to the central line of the second rotating mechanism 5.
