8. A control method for the mobile tilting and lifting system according to claim 4, characterized in that, Includes the following steps: S1. Drive the vehicle chassis (1) to the designated site and pull the swing locking pin out from the pin hole on the swing arm and the pin hole on the swing vehicle. S2. Extend each leveling hydraulic outrigger (11) to support the ground and lift the wheels of the vehicle chassis (1) off the ground. Drive the extension arm (12) to unfold through the extension cylinder (14), perform the leveling action and extend each wind-resistant hydraulic outrigger (13) to touch the ground. Stop the leveling action after the vehicle chassis (1) reaches the required level, and insert the unfolding locking pin into the pin hole on the unfolding arm and the pin hole on the unfolding vehicle. S3. Drive the horizontal locking cylinder (5) to pull the horizontal locking pin out of the horizontal locking hole (24), drive the lifting tower (2) to flip by the lifting cylinder (4), stop the lifting cylinder when the lifting tower (2) flips to a vertical state, and drive the vertical locking cylinder to insert the vertical locking pin into the vertical locking hole (25). S4. Drive the receiving position locking cylinder to pull the receiving position locking pin out of the receiving position locking hole, drive the lifting tower (2), pan-tilt (3) and signal transceiver equipment to rise by the lifting cylinder, stop the lifting cylinder when it is raised to the position, and drive the lifting position locking cylinder to insert the lifting position locking pin into the lifting position locking hole. S5. Adjust the pitch and azimuth angles of the gimbal (3) by adjusting the pitch and azimuth rotation mechanisms respectively, so that the signal transceiver equipment installed on the gimbal (3) is oriented to meet the signal transmission and reception requirements.

9. The control method according to claim 8, characterized in that, It also includes the following steps: S6. Rotate the gimbal (3) to the initial pitch angle position of 0° through the pitch rotation mechanism, and rotate the gimbal (3) to the initial azimuth angle position of 0° through the azimuth rotation mechanism. S7. Drive the lifting position locking cylinder to pull the lifting position locking pin out of the lifting position locking hole. Drive the lifting cylinder to lower the lifting tower (2), pan-tilt (3) and signal transceiver equipment. Stop the lifting cylinder when it is lowered to the position. Drive the receiving position locking cylinder to insert the receiving position locking pin into the receiving position locking hole. S8. Drive the vertical locking cylinder to pull the vertical locking pin out of the vertical locking hole (25), drive the lifting cylinder (4) to flip the lifting tower (2), stop the lifting cylinder when the lifting tower (2) flips to a horizontal state, and drive the horizontal locking cylinder (5) to insert the horizontal locking pin into the horizontal locking hole (24). S9. Pull out the expansion locking pin from the pin hole on the expansion arm and the pin hole on the expansion vehicle, so that each wind-resistant hydraulic support leg (13) and each leveling hydraulic support leg (11) are retracted into place. Then, drive the expansion swing arm (12) to swing back through the expansion cylinder (14). When the expansion swing arm (12) swings back into place, insert the swing back locking pin into the pin hole on the swing back arm and the pin hole on the swing back vehicle. S10. Drive the vehicle chassis (1) away from the designated site.
