At the same time, the transmission mechanism synchronously transmits power to the first output gear shaft, so that the first output gear shaft and the second output gear shaft are simultaneously engaged with the slewing support bearing, rotate along the gear ring, and transmit power to the slewing support bearing. Because the one-to-two gearbox and the tower are fixed after position adjustment through the adjustment assembly, the slewing support bearing drives the tower to rotate. Because one input shaft drives the two output gear shafts to rotate, the complexity of the prime mover system control is effectively reduced and the installation space is saved. Due to the cooperation of the transmission mechanism and the transfer mechanism, the two output gear shafts output power in real time and synchronously, thereby making the load uniform and the load-bearing capacity better. Therefore, the present invention can not only rotate 360°, but also ensure the real-time and synchronous output power of the two output gear shafts, and the load-bearing capacity is better.

[0018] 3. In a rotary mechanism driven by one-to-two gearboxes, the input shaft is located above the square flange, the first output gear shaft and the second output gear shaft are located below the square stop, the screws pass through the U-shaped hole and the threaded hole in sequence to fix the square flange to the mounting surface, the size of the first short side and the second short side of the square stop is smaller than the size of the first mounting side and the second mounting side of the gearbox mounting hole, and the first short side and the second short side are in clearance with the first mounting side and the second mounting side; when used, the square stop is installed in the gearbox mounting hole, and the position of the square stop in the gearbox mounting hole is adjusted by the adjustment component, so that the two output gear shafts are well meshed with the slewing support bearing, and the screws are passed through the U-shaped hole on the square flange and the threaded hole on the mounting surface to fix them, so that the one-to-two gearbox is fixed to the hanging tower, because the U-shaped hole on the square flange allows the gearbox to move back and forth within a certain range, so the application range is wide, the adjustment and installation operations are convenient, and the efficiency is high. Therefore, the present invention not only has good synchronization and uniform load, but also has a wide application range, convenient operation and high efficiency.

[0062] Embodiment 4: The basic content is the same as that of Example 1, except that: the adjusting pad group 51 includes a first adjusting pad 511 and a second adjusting pad 512; one end of the first adjusting pad 511 is in contact with one end of the adjusting screw 52, ​​and the threaded end of the adjusting screw 52 is threadedly connected with one end of the second adjusting pad 512; the inclined surfaces of the first adjusting pad 511 and the second adjusting pad 512 are respectively matched with the inclined surfaces of the inclined surface stopper 42; the straight edges of the first adjusting pad 511 and the second adjusting pad 512 are respectively fitted with the edges of the square flange 35; and an external hexagonal block 521 is provided in the middle of the adjusting screw 52.

[0063] When in use, first loosen the nut 53, then turn the outer hexagonal block 521 of the adjusting screw 52 to increase the distance between the first adjusting pad 511 and the second adjusting pad 512, and push the first adjusting pad 511 and the second adjusting pad 512 along the inclined surface of the inclined surface block 42 toward the long side direction of the square flange 35, thereby pushing the one-to-two gear box 3 toward the direction close to the slewing support bearing 2, until the first output gear shaft 32 and the second output gear shaft 33 of the one-to-two gear box 3 are accurately meshed with the gear ring of the slewing support bearing 2 at the same time, and then tighten the nut 53 and the adjusting screw 52 to fix the position, so that the meshing of the two output gear shafts with the slewing support bearing 2 is more precise, and the adjustment operation is more convenient and efficient.

[0064] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed by the present invention should be included in the protection scope recorded in the claims.
