Abstract
The utility model relates to an electric lifting antenna rod in order to solve automatic fast lifting of a communication antenna in the process of removal. The electric lifting antenna rod is composed of a motor, a speed reducer, a screw bolt, a rod body, a wire take-up disk, a control box, etc., wherein, the motor rotates through driving the screw bolt by the speed reducer to drive a nut arranged on the rod body to rise. After the rod body rises to the position, the rod body realizes interstage automatic positioning locking under the action of a localizer, drives the next stage rod body to continuously and orderly rise to the scheduled position under the action of a range limit baffle ring, and keeps a work state; when the rod body is taken away, the motor contrarotates to realize fast falling taking up. The utility model is applied to fast lifting of vehicular ground equipment, and removable or fixing antenna systems, which is especially suitable to be arranged on a square cabin.
Description
The utility model relates to a kind of vertical antenna lever apparatus, is mainly used in the vehicle-mounted ground equipment in radio communication, the measuring and controlling equipment, fixing or mobile electric up-down mast.
Along with the development of microwave communication, radio measuring and controlling equipment, need various height, load capacity mast strong, that liftable moves to support antenna transmission system.The Pneumatic elevation antenna rod devices that adopt in the existing mobile communcations system more, it mainly is the mast working cylinder of being dressed up by the some pipe joint covers that have piston, the mast lifting is to utilize compressed-air actuated pressure, the antenna on mast and top thereof is upwards elected, each joint is lifted predetermined height, utilize the dedicated fixed folder from top to down that respectively saves cannula tip to clamp by saving the sleeve pipe that will overlap therein, to keep the height of antenna by artificial; Inflation earlier during the decline antenna, venting again need be saved land by an artificial top-down joint one and unclamp geometrical clamp.This device needs the manual operation geometrical clamp, closes or opens air valve in vertical antenna bar process, the supporting instructions for use of the fast automatic communication system of incompatibility.
Chinese patent 94230737.2 has been reported " a kind of automatic lifting mast; saved dedicated fixed folder and manual control switch's air valve on the every joint of mast top; but utilize air compressor, gas tank, pressure switch and other valve; work; add feeder automatic deploying and retracting line mechanism, realize fast automatic lifting " under DC motor is controlled.This Pneumatic elevation bar has overcome the deficiencies in the prior art, but these two kinds of Pneumatic elevation bars all are to utilize " cylinder-piston " relation that constitutes between adjacent two joints of aluminum pipe to reach the lifting of mast.Because " cylinder-piston " lifting requires mast machining accuracy height, complex structure, auxiliary device many, before mast did not descend, all auxiliary devices were all in running order, and consumed energy is many, is unsuitable for long-term use.
