The pan / tilt head 3 is installed on the innermost tower frame 21 of the lifting tower 2 and is used to load the signal transceiver equipment.

[0034] The above configuration constitutes a mobile flip lifting system with high lifting height, excellent strong wind resistance, simple structure, good stability, high safety and strong practicality. In practical application, the vehicle chassis 1 is driven to the predetermined site, the lifting tower 2 is flipped from a horizontal state to a vertical state by the erection cylinder 4, and the lifting tower 2, the pan / tilt 3 and the signal transceiver 100 are lifted to the required height by the lifting cylinder, so that the signal transceiver 100 can work normally. The present invention provides a vehicle chassis 1, which can be quickly moved to a predetermined site as needed, thereby improving the convenience of movement; the vehicle chassis 1 is leveled by providing a leveling hydraulic support leg 11, thereby improving stability and safety; the extended swing arm 12 and the wind-resistant hydraulic support leg 13 are provided, so that the extended swing arm 12 is unfolded and the wind-resistant hydraulic support leg 13 is auxiliary supported on the ground during operation, thereby improving the strong wind resistance performance and enhancing stability and safety; the extended oil cylinder 14 is provided to improve the convenience of unfolding and swinging back the extended swing arm 12; the horizontal locking hole 24 and the matching horizontal locking oil cylinder 5 and the horizontal locking pin are provided to ensure the stability and reliability of the lifting tower 2 in the horizontal state; the vertical locking hole 25 and the matching vertical locking oil cylinder and the vertical locking pin are provided to ensure the stability and reliability of the lifting tower 2 in the vertical state. It should be noted that the lifting tower 2 is an existing device in the art, and its structure, principle and setting method are well known to technicians. The present invention usually makes the lifting tower 2 adopt a multi-layer tower linkage structure to facilitate lifting control; the signal transceiver device refers to antennas, lightning protection devices, anemometers and other equipment. However, it should be pointed out that the mobile flip lifting system provided by the present invention is not limited to signal transceiver equipment, but can also be used in other occasions where specific devices or equipment need to be lifted to a certain height, and the technical purpose of the present invention can also be achieved. In addition, in order to ensure the state stability of the lifting tower 2, when it is in a lying state, the lying locking pin is driven by the lying locking cylinder 5 to be inserted into the lying locking hole 24, and when it is in a vertical state, the vertical locking pin is driven by the vertical locking cylinder to be inserted into the vertical locking hole 25.

[0035] As an optimization scheme, this specific embodiment sets a lifting and locking cylinder in position and a receiving and locking cylinder in position on the lifting tower 2, as well as a lifting and locking hole in position and a receiving and locking hole in position corresponding to the lifting and locking cylinder in position and the receiving and locking cylinder in position, wherein the piston rod of the lifting and locking cylinder in position is connected with a lifting and locking pin shaft that matches the lifting and locking hole in position, and the piston rod of the receiving and locking cylinder in position is connected with a receiving and locking pin shaft that matches the receiving and locking hole in position.

At the same time, in order to make the leveling hydraulic legs 11 and the wind-resistant hydraulic legs 13 have the ability to maintain their state, the specific implementation method uses a locking hydraulic cylinder for the leveling hydraulic legs 11 and the wind-resistant hydraulic legs 13. After the vehicle chassis 1 is leveled, the locking function of the two can be used to support the leveling hydraulic legs 11 and the wind-resistant hydraulic legs 13 on the ground and maintain a locked state, thereby improving stability and safety. Practical application shows that the use of the locking function of the leveling hydraulic legs 11 and the wind-resistant hydraulic legs 13, in conjunction with the vertical locking cylinder, the lifting locking cylinder and its matching locking pin shaft, can ensure that the mobile flip lifting system can be used normally in a strong wind environment of level 13.
