DETAILED DESCRIPTION

[0029] The specific implementation of the present invention is described below in conjunction with the accompanying drawings;

[0030] Reference Figures 1 to 8The antenna lifting rod of this embodiment is composed of a lifting rod body 1, a turntable 2, a pitch mechanism 3, a lifting scissor chain 4, and a retractable wire wheel group 5. The lifting rod body 1 is the main body and support of the entire mechanism, and the bottom is fixedly connected to the mobile platform or the fixed platform by bolts. The lifting rod body 1 is composed of a rod body 1-1, a lifting motor and a reduction device 1-2. The top of the lifting rod body 1 is provided with a flange interface I1-3, the top side is provided with a connecting seat I1-4, and the bottom side is provided with a connecting seat II1-5. The action of the lifting motor and the reduction device 1-2 can realize the lifting and lowering of the antenna rod and the turntable 2, the pitch mechanism 3, and the retractable wire wheel group 5 carried by it, and at the same time unfold or close the lifting scissor chain 4. The turntable 2 is composed of a turntable 2-1, a connecting rod 2-2, a rotating motor and a speed reducer 2-3. The turntable 2 is provided with a connecting flange II2-4 at the bottom, which is fixedly connected to the flange interface I1-3 of the lifting rod body 1 by bolts. The action of the rotating motor and the speed reducer 2-3 can realize the rotation of the turntable 2 and the pitch mechanism 3 carried by it, and at the same time, the retracting and releasing wire wheel group 5 can realize the retracting and releasing wire action. The pitch mechanism 3 is composed of a pitch motor and a speed reducer 3-1 and a pitch rod 3-2. The pitch mechanism 3 is fixedly connected to the turntable 2-1 of the turntable 2 by bolts. The action of the pitch motor and the speed reducer 3-1 can realize the pitch action of the carried antenna. The upper and lower ends of the lifting scissor chain 4 are respectively fixedly connected to the connecting seat I1-4 and the connecting seat II1-5 of the lifting rod body 1 by bolts. The lifting scissor chain 4 can be unfolded and stored with the lifting and lowering of the lifting rod body 1, thereby realizing the unfolding and storage of the cable. The retractable and retractable wire wheel assembly 5 is composed of a coil spring driven wheel 5-1, a driving wheel 5-2, and a supporting structure 5-3. The supporting structure 5-3 is fixedly connected to the lifting rod body 1 by bolts, and the driving wheel 5-2 is fixedly connected to the connecting rod 2-2 of the turntable 2 by bolts. The retractable and retractable wire wheel assembly 5 can realize the retraction and release of the cable under the action of the coil spring driven wheel 5-1 and the driving wheel 5-2 as the turntable 2 rotates.

[0031] Deployment steps: First, the lifting motor and reduction device 1-2 rotate forward, the rod body 1-1 rises, and at the same time, the upper end of the lifting scissors chain 4 moves with it. The lifting scissors chain 4 is unfolded from the stored state. After the rod body 1-1 reaches the specified height, the lifting motor and reduction device 1-2 stop moving. Then the rotating motor and reduction device 2-3 are activated, the turntable 2 rotates, and at the same time drives the driving wheel 5-2 to rotate, and the cable is rolled from the winding spring driven wheel 5-1 to the driving wheel 5-2. After reaching the specified rotation angle, the rotating motor and reduction device 2-3 stop rotating. Finally, the pitch motor and reduction device 3-1 are activated, driving the carried antenna to perform a pitch movement. After reaching the specified pitch angle, the pitch motor and reduction device 3-1 stop moving. At this point, the deployment action is completed. The deployment state is as follows: Figure 4 shown.

[0032] Storage steps: The pitch motor and reduction device 3-1 are activated, driving the carried antenna to perform a pitch movement. After the pitch angle returns to zero, the pitch motor and reduction device 3-1 stop moving. Then the rotating motor and reduction device 2-3 are activated, the turntable 2 rotates, and at the same time drives the driving wheel 5-2 to rotate. Under the action of the winding spring driven wheel 5-1, the cable is wound from the driving wheel 5-2 to the winding spring driven wheel 5-1. After the rotation angle returns to zero, the rotating motor and reduction device 2-3 stop rotating. Finally, the lifting motor and reduction device 1-2 reverse, the rod body 1-1 descends, and the upper end of the lifting scissors chain 4 follows. The lifting scissors chain 4 is stored from the unfolded state. After the rod body 1-1 descends to the specified height, the lifting motor and reduction device 1-2 stop moving, and the storage action is completed. The storage state is as follows: Figure 1 shown.

[0033] Reference Fig. 9 The rod body 1-1 of the lifting rod is mainly composed of a first section tube 1-1-1, a second section tube 1-1-2, a third section tube 1-1-3, a fixed pulley 1-1-4, a lead screw 1-1-5 and a nut 1-1-6, and a wire rope 1-1-7.

[0034] The rod body 1-1 is fixedly connected to the lifting motor and the reduction device 1-2 by bolts.

[0035] The first tube section 1-1-1, the second tube section 1-1-2 and the third tube section 1-1-3 are sleeved, the third tube section 1-1-3 is at the outermost part and the first tube section 1-1-1 is at the innermost part, and each tube section can move in the axial direction.

[0036] The fixed pulley 1-1-4 is fixed on the inner top of the second tube section 1-1-2.

[0037] The lead screw 1-1-5 is fixedly connected to the output shaft of the lifting motor and the reduction device 1-2.

[0038] The nut 1-1-6 is fixedly connected to the bottom of the second tube section 1-1-2 and forms a screw nut pair with the screw 1-1-5.

[0039] The steel wire rope 1-1-7 passes through the fixed pulley 1-1-4, and both ends of the steel wire rope are respectively fixed to the inner bottom of the first section tube 1-1-1 and the third section tube 1-1-3.

[0040] Working principle:

[0041] Ascending process: the lifting motor and the reduction device 1-2 rotate forward, driving the lead screw 1-1-5 to rotate forward, and then driving the nut 1-1-6 to move. Since the lead screw 1-1-5 is fixed on the lifting motor and the reduction device 1-2, the lead screw 1-1-5 can only rotate around the axis, and the nut 1-1-6 rises linearly along the axis, and then drives the second tube 1-1-2 and the fixed pulley 1-1-4 to do the ascending movement. Since the two ends of the wire rope 1-1-7 are respectively fixed on the first tube 1-1-1 and the third tube 1-1-3, and the length of the wire rope is constant, when the fixed pulley 1-1-4 moves upward, the wire rope 1-1-7 pulls the third tube 1-1-3 to do the ascending movement until it reaches the specified position to complete the ascending action.

[0042] Descending process: the lifting motor and the reduction device 1-2 reverse, driving the lead screw 1-1-5 to reverse, and then driving the nut 1-1-6 to move. Since the lead screw 1-1-5 is fixed on the lifting motor and the reduction device 1-2, the lead screw 1-1-5 can only rotate around the axis, and the nut 1-1-6 descends linearly along the axis, and then drives the second tube 1-1-2 and the fixed pulley 1-1-4 to descend. Since the two ends of the wire rope 1-1-7 are respectively fixed on the first tube 1-1-1 and the third tube 1-1-3, and the length of the wire rope is constant, when the fixed pulley 1-1-4 descends, the wire rope 1-1-7 pulls the third tube 1-1-3 to descend until it reaches the designated position to complete the descending action.

[0043] The present invention has the following characteristics:

[0044] 1. The structure of the lifting antenna pole with a turntable and pitch mechanism can realize the three-dimensional movement of the antenna: lifting, rotating and pitching;

[0045] 2. Equipped with lifting scissor chain and retracting and releasing wire wheel set, it can meet the automatic retraction and release of cables in the form of antenna lifting, rotation and pitching motion, without the need for manual installation;

[0046] The three-dimensional movement is all driven by servo motors. The lifting scissor chain and the retracting and releasing wire wheel can automatically retract and release the cable while the antenna is raised and lowered and rotated. With the controller, it can be deployed and stored with one button. The operation is simple, the deployment is fast, and the movement is precise.
