The multi-path microwave rotary joint assembling device according to claim 2, further comprising a device housing (8), wherein the device housing (8) is arranged at the periphery of the platform frame (1), and a status indicator lamp (802) and a control key (803) are arranged on the device housing (8).
10. An assembling method using the multi-path microwave rotary joint assembling device according to any one of claims 1 to 7, comprising the steps of:
adjusting equipment, namely adjusting a lifting mechanism (3) to a proper height, adjusting a slewing mechanism (4) to a horizontal position, and arranging rotary joint clamping jaws (6) on a clamp sliding rail (501) to a proper position;
clamping the first group of rotating modules, and stably clamping the topmost group of rotating modules (201) through a group of rotating joint clamping jaws (6) at the top end of a clamp bracket (5);
thirdly, pre-installing the horizontal posture of the rotary module, enabling the semi-rigid coaxial cables (202) carried by the rotary module (201) clamped in the second step to penetrate through the inner cavity of the subsequent group of rotary modules (201), clamping and fixing the subsequent group of rotary modules through the clamping jaws (6), reserving an adjusting gap, temporarily not splicing with the previous group, and binding the semi-rigid coaxial cables (202) in corresponding holes of a cable limiting disc (503) after combing;
step four, the vertical postures of the rotating modules are accurately butted, the rotating mechanism (4) is adjusted to the vertical posture, and the lifting mechanism (3) is adjusted to the assembling height; aligning an end face sealing ring (203), a radial sealing ring (204) and a transmission shifting fork (205), loosening a clamping jaw locking screw (606) after a semi-rigid coaxial cable (202) is combed neatly, and uniformly pressing down to assemble two groups of two-way rotating modules (201) in place;
and step five, repeating the step three and the step four to finish the assembly of the multi-path microwave rotary joint (2).
