Self-rotating lifting rod

Abstract

The invention discloses a self-rotating lifting rod. The lifting rod comprises a pipe body and a lead screw driving device of the pipe body, wherein the pipe body is provided with a bottom pipe; the lead screw driving device includes a lead screw and a lifting motor; the lifting motor is matched with a power input end of a bottom end of the lead screw through a gear set arranged in a first gear box below the bottom pipe so that the lead screw can be driven to rotate; and the gear set includes a first driven gear arranged at a power input end of a bottom end of the lead screw and a first driving gear driven by the lifting motor, and the bottom pipe can rotate with an axis of the bottom pipe as a shaft. According to the self-rotating lifting rod, the bottom pipe can rotate with the axis of the bottom pipe as the shaft, then the whole pipe body can be driven to rotate, an orientation rotary table does not need to be additionally arranged on the lifting rod and a lifting load is not increased, and the whole lifting rod does not need to be installed on the rotary table and a large rotation space does not need to be occupied.

Description

technical field [0001] The invention relates to a lifting rod, in particular to a self-rotating lifting rod. Background technique [0002] A lifting mast with a certain lifting capacity can be used to quickly erect communication facilities such as antennas. The basic structural composition of the lifting rod in the prior art mainly includes the pipe body and the screw drive device of the pipe body. The pipe body has a plurality of round pipes with diameters ranging from large to small, and the outermost pipe is the bottom pipe. , the innermost tube is the top tube, and the rest of the tubes are inner tubes. The screw driving device includes a screw and a screw drive motor. The screw drive motor is driven by the clutch, gear and the power input end at the bottom of the screw. The lead screw rotates and stops, and then through the corresponding cooperation between the pipe body and the lead screw, it can drive the jacking of the pipe body and the inner pipe to rise and fall s...

Problems solved by technology

The previous method: one is to add an azimuth turntable between the antenna and the lifting mast, and the antenna is adjusted in azimuth through the turntable. The disadvantage of this method is that it increases the load of the mast, which affects the service life of the mast to a certain extent. ;Another method is to install the lifting rod on the turntable as a whole, so that the lifting rod is rotated as a whole to adjust the azimuth. The disadvantage of this method is that the turning space is too large, which causes certain difficulties for installation.
