The slider 34 and the outer cylinder slide groove 32 have another function of preventing the antenna outer cylinder 30 and the antenna support plate 33 from rotating relative to each other.

The equidistance of support piece 23 is equipped with a plurality of groups to fixed connection is on the inner wall of outer tube 20, the equidistance is fixed to be equipped with corresponding jacking piece 25 on the lift stay tube 21, be equipped with one-way bearing 24 in the support piece 23, the fixed slide rail 241 that is equipped with on the inner circle lateral wall of one-way bearing 24, and the inner circle upper end of one-way bearing 24 is equipped with brake tooth 240, be equipped with corresponding stay tube spout 210 on the lift stay tube 21 lateral wall, be equipped with in the support piece 23 with brake tooth 240 matched with brake strip 26. Since the braking bar 26 is engaged in the teeth groove of the braking teeth 240, the inner ring of the one-way bearing 24 and the support 23 cannot rotate, and the slide rail 241 on the inner ring of the one-way bearing 24 limits the relative rotation between the elevation support tube 21 and the inner ring of the one-way bearing 24, i.e. the elevation support tube 21 cannot rotate relative to the outer tube 20. Therefore, when the motor 12 controls the driving rod 22 to rotate forward slowly, the elevation supporting tube 21 is driven by the driving rod 22 to ascend slowly because the elevation supporting tube 21 cannot rotate in the initial stage, and further the antenna supporting plate 33 (the main antenna 4 and the branch antenna 5) is driven to ascend slowly until the jacking piece 25 on the elevation supporting tube 21 jacks the supporting piece 23. After the jacking member 25 abuts against the supporting member 23, the braking bar 26 is lifted up to be separated from the tooth groove of the braking teeth 240, and then the inner ring of the one-way bearing 24 is loosened, and the jacking member 25 abuts against the supporting member 23 to prevent the lifting support tube 21 from rising, so that after that, although the motor 12 still controls the driving rod 22 to rotate forward slowly (the rotation state of the motor 12 is not changed), the lifting support tube 21 does not rise any more, but rotates forward slowly along with the driving rod 22 together with the inner ring of the one-way bearing 24, and then drives the antenna supporting plate 33 (the main antenna 4 and the supporting antenna 5) to rotate forward slowly.

When the main antenna 4 and the branch antenna 5 need to be retracted for protection, the motor 12 is slowly rotated in the reverse direction, and since the inner ring of the one-way bearing 24 cannot be rotated in the reverse direction, the lifting support tube 21 is changed to a non-rotatable state, and therefore, the motor 12 controls the drive rod 22 to slowly rotate in the reverse direction, so that the lifting support tube 21 is slowly lowered under the drive of the drive rod 22, and further, the antenna support plate 33 (the main antenna 4 and the branch antenna 5) is slowly lowered until being completely retracted into the antenna outer tube 30, and finally, the motor 12 is turned off.

Brake bar 26 bottom is fixed and is equipped with lifter 260 and spacing gleitbretter 261, lifter 260 lower extreme passes support piece 23 and exposes partly, and with support piece 23 sliding connection, still the cover is equipped with reset spring 262 on the lifter 260, reset spring 262 is located support piece 23, and connect between support piece 23 and lifter 260, spacing gleitbretter 261 sliding connection is in support piece 23. The lower end of the lifting rod 260 penetrates through the supporting piece 23 and is partially exposed, so that when the jacking piece 25 jacks the supporting piece 23, the lifting rod 260 can be jacked up, the braking strip 26 is jacked up, the limiting sliding piece 261 is used for ensuring that the braking strip 26 only can move up and down and cannot rotate, and the reset spring 262 ensures that the jacking piece 25 descends to separate from the supporting piece 23, and then the braking strip 26 can automatically descend to clamp the one-way bearing 24 again.

The bottom of the support member 23 is further provided with a plurality of balls 27, the balls 27 are located in a ball groove 270 in the support member 23, a ball bearing plate 272 is arranged in the ball groove 270, the ball bearing plate 272 abuts against the balls 27, and a compression spring 271 is connected between the ball bearing plate 272 and the ball groove 270. The balls 27 serve to smooth the relative sliding between the elevating member 25 and the supporting member 23 when the elevating supporting pipe 21 is rotated after the elevating member 25 abuts against the supporting member 23.

The distance between the adjacent supporting pieces 23 is equal to the distance between the adjacent jacking pieces 25, and is less than the length of the threaded part at the bottom of the driving rod 22. When the jacking piece 25 is jacked against the support piece 23, the threaded part arranged at the bottom of the driving rod 22 and the part provided with the internal thread arranged at the bottom of the lifting support pipe 21 are not separated, so that the driving rod 22 can smoothly control the lifting, rotating and descending of the lifting support pipe 21.

The specific implementation mode and principle are as follows:

the signal tower is fixedly arranged on the ground or other base stations through the bottom plate 11, and then when an antenna is needed to be used, the motor 12 is started to rotate forwards. Since the brake bar 26 is initially caught in the tooth groove of the brake teeth 240, the inner ring of the one-way bearing 24 and the support 23 cannot rotate, and the slide rail 241 on the inner ring of the one-way bearing 24 restricts the relative rotation between the elevation support tube 21 and the inner ring of the one-way bearing 24, i.e., the elevation support tube 21 cannot rotate relative to the outer tube 20. Therefore, when the motor 12 controls the driving rod 22 to rotate forward slowly, the elevation supporting tube 21 is driven by the driving rod 22 to ascend slowly because the elevation supporting tube 21 cannot rotate in the initial stage, and further the antenna supporting plate 33 (the main antenna 4 and the branch antenna 5) is driven to ascend slowly until the jacking piece 25 on the elevation supporting tube 21 jacks the supporting piece 23.

During the slow ascending process of the antenna supporting plate 33 (the main antenna 4 and the branch antenna 5), the distance between the antenna supporting plate 33 and the extension cable connector 44 at the top of the driving rod 22 is extended (the extension cable connector 44 is rotatably connected with the top of the driving rod 22, so that during the ascending process of the lifting supporting tube 21, the extension cable connector 44 slides downwards along the connector groove 330 relative to the antenna supporting plate 33), that is, the extension cable 55 is pulled out by force, when the extension cable 55 is pulled out from the branch antenna 5, because the extension cable 55 is folded in the branch antenna 5, the extension cable 55 is forced to be unfolded after being pulled out, and further, the branch antenna 5 is extended.

When the jacking member 25 jacks the support member 23, the lifting rod 260 is jacked up, and the braking bar 26 is jacked up, and is separated from the tooth groove of the braking teeth 240, and the inner ring of the one-way bearing 24 is loosened, and the jacking member 25 jacks the support member 23, so that the lifting support tube 21 cannot rise any more, so that, until then, the motor 12 still controls the driving rod 22 to rotate slowly forward (the rotation state of the motor 12 is not changed), but the lifting support tube 21 does not rise any more, and slowly rotates forward along with the driving rod 22 together with the inner ring of the one-way bearing 24, and further drives the antenna supporting plate 33 (the main antenna 4 and the branch antenna 5) to rotate slowly forward (at this time, the branch antenna 5 also extends completely, the main antenna 4 also rises to the top point, and the antenna supporting plate 33 drives the main antenna 4.

When the antenna is not used or severe weather such as typhoon occurs, the main antenna 4 and the branch antenna 5 need to be retracted for protection, the motor 12 stops rotating forward, the motor 12 is started to rotate in reverse, because the inner ring of the one-way bearing 24 cannot rotate in reverse, the lifting support tube 21 becomes a non-rotatable state again, the motor 12 controls the driving rod 22 to rotate in reverse slowly, so the lifting support tube 21 will descend slowly under the driving of the driving rod 22 (after the lifting piece 25 is separated from the supporting piece 23, the braking strip 26 will descend automatically and clamp the one-way bearing 24 again under the action of the return spring 262), further the antenna supporting plate 33 (the main antenna 4 and the branch antenna 5) is driven to descend slowly, and the distance between the antenna supporting plate 33 and the extension cable connecting piece 44 at the top of the driving rod 22 is shortened in the process that the antenna supporting plate 33 (the main antenna 4 and the branch antenna 5) descends slowly, the extension cable 55 is released, the automatic cable retracting disc 41 rotates and retracts the retracting cable 56 under the action of the torsion spring 45, so that the branch antenna 5 retracts into the main antenna 4, then retracts into the antenna outer cylinder 30 together with the main antenna 4 completely, and finally the motor 12 is turned off.

Based on the above, the tower-shaped antenna is arranged to be capable of placing the antenna at a high position, arranging the main antenna and the branch antenna to be matched for use and rotating when the antenna is arranged for use, so that the signal receiving and sending capability of the antenna is enhanced in three aspects; the antenna is convenient to install on the top of the tower, the antenna is folded and unfolded and the antenna is controlled by a motor drive and a matching mechanical mechanism, the integrated drive and control are realized, the control complexity is low, and interference cannot occur.
