[0041] As shown in Figure 1 and Figure 4 In some embodiments, the third adjusting assembly 142 includes a third driving member 1421, a third screw rod 1422 in transmission connection with the third driving member 1421, a transmission nut mechanism 1423 in transmission connection with the third screw rod 1422, and a connecting plate 1425 connected with the transmission nut mechanism 1423, the connecting plate 1425 being connected with the fourth base 151. In some embodiments, the third base 141 is connected with the Y-direction guide block 134 in the Y-direction adjusting unit through screws, the rotating assembly 143 is installed in the center of the third base 141 through screws, the third screw rod 1422 and the transmission nut mechanism 1423 are in thread fitting to form an assembly, and the assembly is installed together with the bearing support part of the third screw rod 1422 and the third support bearing seat 1429, the third support bearing seat 1429 being fixed on the third base 141 through screws, and the connecting plate 1425 is installed on the upper end of the transmission nut mechanism 1423 through screws. The third driving member 1421 can be a third hand wheel, and by rotating the third hand wheel, the transmission nut mechanism 1423 is driven to change from linear motion to arc motion, so as to realize Z-direction rotation.

[0042] As shown in Figure 4 and Figure 5 In some embodiments, the transmission nut mechanism 1423 includes a stop block 1426 connected with the connecting plate 1425, a rotating bearing 1427 fixedly connected with the stop block 1426, a nut connecting seat 1428 connected with the rotating bearing 1427, and a third nut 1424 connected with the nut connecting seat 1428; that is, the connecting plate 1425 can rotate in the nut connecting seat 1428 through the rotating bearing 1427, the stop block 1426 includes two vertically arranged circular stop columns, the connecting plate 1425 is T-shaped, the vertical rod of the connecting plate 1425 is arranged between the two circular stop columns, and the horizontal plate of the connecting plate 1425 is connected with the circular stop columns. By rotating the third driving member 1421, the third nut 1424 on the third screw rod 1422 is driven to move, and since there is a rotating space above the third nut 1424 for arc swinging, the connecting plate 1425 can be controlled to change from linear motion to arc motion, so as to realize Z-direction rotation of the fourth base 151.

[0043] As shown in Figure 4 and Figure 5 In some embodiments, the angle of Z-direction rotation of the fourth base 151 relative to the third base 141 is -5°-5°. It can be -5°, -2.5°, -1°, 0°, 1°, 2°, 3°, or 5°. Since it is necessary to change the linear motion of the connecting plate 1425 into arc motion, the angle of Z-direction rotation of the fourth base 151 relative to the third base 141 is relatively small. That is, the change from linear motion to arc motion can be realized through the transmission nut assembly.

[0044] As shown in Figure 4 and Figure 6 In some embodiments, the third base 141 is also provided with a plurality of support rollers 144 arranged annularly around the rotation support shaft 1432. In some embodiments, the support rollers 144 are fixed on the third base 141 by screws. When the fourth base 151 rotates Z-ward relative to the third base 141, the support rollers 144 serve as guides.

[0045] In some embodiments, the rotating assembly 143 comprises, in sequence, a flange connection plate 1431, a rotation support shaft 1432, a spacer ring 1433, a planar thrust bearing 1434, a spacer sleeve 1435, an adjusting ring 1436, a deep groove ball bearing 1437, and a bearing support seat 1438, the flange connection plate 1431 being connected with the fourth base 151.

[0046] As shown in Figure 7 In some embodiments, the fourth adjusting assembly comprises a lifting mechanism 152 and a support 153 connected with the output end of the lifting mechanism 152, the support 153 being used for supporting the inverted mirror frame. The fourth base 151 and the flange connection plate 1431 are connected and fixed by screws, the lifting mechanism 152 can be an electric lifting cylinder, the electric lifting cylinder is fixed on the fourth base 151 by screws, the side of the fourth base 151 away from the lifting mechanism 152 is fixed with the connecting plate 1425 by screws, and the fourth base 151 is adjusted to rotate Z-ward under the driving of the Z-ward rotation adjusting unit 140. In some embodiments, the support 153 is a support plate used for supporting the inverted mirror frame.

[0047] As shown in Figure 7 In some embodiments, the lifting mechanism 152 is provided with a plurality of groups, and the plurality of groups of lifting mechanisms 152 are arranged annularly around the rotation support shaft 1432. In some embodiments, the lifting mechanism 152 is provided with four groups, the lifting mechanism 152 can be an electric lifting cylinder, and the four electric lifting cylinders are arranged annularly around the rotation support shaft 1432. Each electric lifting cylinder is provided with a support 153 on the upper surface, and the plurality of support points can better support the inverted mirror frame.

[0048] As shown in Figure 7As shown, in some embodiments, a universal adjusting bearing 154 is further provided between the lifting mechanism 152 and the support 153, one end of the universal adjusting bearing 154 is fixedly connected with the lifting mechanism 152, and the other end is rotatably connected with the support 153. In some embodiments, the universal adjusting bearing 154 is installed together with the lifting shaft threaded end of the electric lifting cylinder through threads, and the support 153 is installed together with the universal adjusting bearing 154 through a pin shaft 155, that is, the multi-angle adjustment of the support 153 can be realized, so that the support 153 is better matched with the inverted frame.

[0049] Therefore, when the inverted frame needs to be adjusted in the X and Y directions, the first driving member 1211 is rotated to drive the first nut 1213 to complete the adjustment in the X direction under the guidance of the X direction rail 122 and the X direction guide block 123. Since the second base 131 is connected together with the X direction guide block 123 and the first nut 1213 through screws, the second base 131 is adjusted in the X direction relative to the first base 110, at this time all components above the second base 131 are adjusted in the X direction; the second driving member 1321 is rotated to drive the second nut 1323 to complete the adjustment in the Y direction under the guidance of the Y direction rail 133 and the Y direction guide block 134, since the third base 141 is connected together with the Y direction guide block 134 and the second nut 1323 through screws, the third base 141 is adjusted in the Y direction relative to the second base 131, at this time all components above the third base 141 are adjusted in the Y direction.

[0050] As shown in Figure 1 and Figure 8 When the inverted frame needs to be adjusted in the Z direction, the third driving member 1421 is rotated to drive the third nut 1424 on the third screw rod 1422 to move, since there is a rotating space above the third nut 1424 that can swing in an arc shape, the connection plate 1425 can be controlled to change from linear motion to arc motion, so as to realize the Z direction rotation of the fourth base 151. The connection plate 1425 moves together with the fourth base 151, and supports the fourth base 151 to move together in the Z direction through the supporting roller 144 to adjust in the Z direction.

[0051] When the inverted frame needs to be installed, the inverted frame can be placed on the support 153 of the Z direction adjusting unit 150 through the hoisting system, and when the lifting adjustment is needed, only the lifting mechanism 152 needs to be started, which can realize the Z direction height adjustment of the inverted frame.

[0052] Therefore, the adjustment mode of the above-mentioned inverted frame can be flexibly selected according to the actual requirements of the installation site of the inverted frame, so as to ensure that the inverted frame reaches the required posture for installation and fixation.
