Analysis Of The Working Principle Of Elevating Antenna Poles

The lifting antenna mast is quickly and automatically lifted by a DC motor to drive the air compressor through the air tank and pressure switch to generate high-pressure gas to adapt to the quantity of mast tubes. The tube end is connected to the piston of the cylinder, resulting in high-pressure gas. Section by section, the antenna will automatically upgrade to a predetermined height and continue to work, requiring rapid descent and withdrawal of the collapsed equipment before.
An automatic lifting mast, consisting of an air pressure source and several sections connected to the mast tube kit, chassis, and other components, is characterized in that the pressure source, air compressor, check valve, and air storage tank structure in its magnetic motor are output through a unloading valve, a pressure reducing valve, a bidirectional electromagnetic valve, and the next mast cylinder is connected with a control pressure air tank pressure switch and an air tank; The third end of the two position three way is connected to an adjustable flow valve through an electromagnetic valve; The antenna automatic lifting mechanism includes: multiple pipes connected by multiple pistons, which are connected to the base of the large pipe diameter, and the antenna is used as a fixed top outside the diameter of the small pipe section; The piston is a hollow piston equipped with a Y-shaped top ring, characterized in that the device is equipped with a plastic ring and the other end is equipped with an O-ring; One end is fixed to the antenna feed line as an automatic telescopic mechanism, and the other end is fixed to the mast at the top of the pipe; The automatic telescopic wire mechanism includes a spool, a shaft, bearings, a reel bracket, a spring seat, a spring, and a pin. It includes a reel and a baffle plate, a disc that fixes the reel bracket in the shaft frame, a spring seat fixed to the valve, a spring seat, and a spring loaded pin at the center of the bearing sleeve on the shaft, and a rotating joint is set at the other end of the shaft.
