Bar section 1 arrives bar section 6 35, socket screw rod in bar section 6 35, with screw rod rotating bar section 1 to bar section 6 35 take turns doing it is perpendicular
Translation is dynamic to be stretched.
The antenna mast body also includes multiple pulley mechanisms, and steel cable one end of pulley mechanism is with being arranged on the bottom of base pitch 29
Guide bracket 1 is fixedly connected, and it is oppositely extending to adjacent stems section bottom that the other end bypasses the fixed pulley 28 being arranged at the top of adjacent stems section
Guide bracket after continue to extend to fixed pulley 28 at the top of adjacent stems section through guide bracket, the guide bracket of the bar section until being fixed on innermost layer
On, and then adjacent stems section vertical shift is driven by tensing steel cable, make car antenna vertical shift.
In above-mentioned technical proposal, the upper end of bar section 1 to bar section 6 35 is respectively and fixedly provided with a fixed pulley 28, and each bar
Section and the bottom of base pitch 29 are equipped with a guide bracket, and guide bracket 1 is fixed, and guide bracket 2 22 to guide bracket 7 27 is with respective bar section
Mobile, a steel cable one end is fixed on the guide bracket 1 of the bottom of base pitch 29, and the other end is upwardly extended around the top of bar section 1
Fixed pulley 28 after extend oppositely downward, through the guide bracket 2 22 of the bottom of bar section 1 after continue to extend upwardly to the top of bar section 2 31
The fixed pulley 28 at end, then re-extends into the guide bracket 3 23 of the bottom of bar section 2 31, so to the last extends to the bottom of bar section 6 35
Being terminated after the guide bracket 7 27 in portion, steel cable length is definite value, and not in working condition, the steel cable between adjacent guide bracket is relaxed state,
It is coiled in each bar section bottom groove.
Screw rod rotates when operating, and driven rod section 1 rises, and the steel cable in relaxed state is gradually tightened up, due to guide bracket
One 21 be the fixing end of steel cable one end, after being tightened up completely to the steel cable of the bottom guide bracket 2 22 of bar section 1 from guide bracket 1, steel
Rope around bar section 2 31 fixed pulley 28 on the guide bracket 3 23 of the bottom of bar section 2 31, after this section of steel cable is tightened up again, pull
Bar section 2 31 rises, and so circulates until whole steel cable is that tightening state stops.
When work, which finishes, needs the retracted antenna body of rod, contra rotating screw pair 41, screw rod rotates with, driven rod section one
30 decline, because whole steel cable is tight state, therefore the meeting at the guide bracket 2 22 of the bottom of bar section 1 during the decline of bar section 1
Downward pulling force is produced to steel cable, is declined by the pull lever section 2 31 of fixed pulley 28 of bar section 2 31, meeting when bar section 2 31 declines
Downward pulling force is produced to the steel cable at the place of bar section 3 32, pull lever section 3 32 declines, and so circulates until all bar sections are returned to
Initial position stops.
As shown in figure 4, the lifting drive 4 includes motor 42, deceleration device 43 and screw pair 41, the drive
Dynamic motor 42 is connected by deceleration device 43 with screw pair 41, and under motor driving, deceleration device 43 is reduced by gear train and driven
The driving rotating speed of dynamic motor 42, and then control screw pair 41 to be rotated with the high torque slow-speed of revolution.
In above-mentioned technical proposal, motor 42 is used as power source, is provided with gear train in deceleration device 43, is revolved by gear
Transformationization reduces the driving frequency of motor 42, and the drive output of deceleration device 43 is fixedly connected with screw pair 41, and then
Driving force after deceleration is passed into screw pair, drives screw pair 41 to be rotated with the high torque slow-speed of revolution, makes and the screw thread of screw pair 41
The screw rod rotation of connection.Screw rod is threadedly coupled with the nut 36 being fixed on outermost layer bar section 1, and screw rod is with 41 turns of screw pair
Lines vertical shift of the nut 36 according to screw thread is driven when dynamic, while the vertical shift of driven rod section 1, bar section 1 pass through cunning
Taking turns mechanism, driven rod section 2 31 moves to bar section 6 35 successively.
Preferably, the lifting drive 4 also includes the second manual setter 5, is arranged on motor 42 and is filled with slowing down
Between putting 43, crank can be shaken manually when running into special circumstances and motor can not be used to drive, control screw pair 41 rotates；Also may be used
Driven using motor and carry out coarse positioning, be accurately positioned using manual setter, and then control the motion of antenna mast body vertical direction,
Energy consumption is saved, improves efficiency.
As shown in figure 1, the antenna mast body is provided with bar control case 3, perpendicular device is played for monitoring antenna mast body and antenna
State, and assistance for lifting drive device and antenna play the movement of perpendicular device control antenna mast body and antenna.It is provided with bar control case
Protection circuit, it can send alarm signal when some bar section goes wrong and take safeguard measure, such as internal steel wire is wound
Or situations such as fracture, when causing monitoring signals exception, bar control case can cut off the power input of motor, it is ensured that machine and personnel's peace
Entirely, prevent the other positions of machine from further damaging.
