Description
Technical field
The present invention relates to antenna technical field, specially a kind of antenna universal adaptive formula levelling device.
Background technique
It is grown rapidly with causes such as China's space flight measurement and control, satellite communication, astronomical observations, the demand to various antenna is not
Disconnected to increase, in field of antenna, other than wheel-track type antenna, remaining antenna structure system will use levelling device, be badly in need of performance
Excellent, easy to adjust, safe and reliable levelling device.
Antenna structure system is all mounted on cement column foot (basis) at present, since column foot mounting surface levelness is missed
Difference is very big, in order to guarantee the verticality (deep bid levelness) of antenna structure system azimuth axis, it is necessary to increase levelling device to it
It is adjusted, to meet system general requirement.
Antenna cement column foot is reinforced concrete structure, mainly according to the wind load of antenna structure system and interface by antenna
Structure chief engineer proposes design technology requirement, carries out engineering design and construction by the civil engineering company with corresponding qualification, builds.
It is whole that there is enough rigidity, strength and stability, to ensure the dynamic property of the antenna structure under desired wind load action
And safety.
It is provided with basic built-in fitting at the top of column foot, provides good interface for installation antenna.Basis is pre-buried at the top of cement column foot
Part is made of several discrete pre-embedded bolts and one piece of pre-embedded steel slab (ring), and the reinforcing bar inside pre-embedded bolt bottom and column foot passes through
Welding manner is connected as one.Certain engineered cementitious column foot engineering drawing is as shown in Figure 1.
Traditional levelling device is made of Wedged iron, Xia Wedged iron, screw rod, nut and several locking nut attachmentes Shang pedestal, wherein
Pedestal is a bed shape structural member for having backrest and bilateral protection edge, is equipped with nut among backrest, and bed body top surface is provided Wei Wedged iron
Support, bilateral protection provide slideway along for Wedged iron, and bed body bottom surface is levelling device and cement column foot conjunction plane.
Xia Wedged iron is a trapezoidal cuboid, and upper plane is the inclined surface 1:30, and side is equipped with threaded hole, it and screw rod pass through spiral shell
Mother's locking is combined into one, and assembly can slide in longitudinal card slot of pedestal along screw axis direction.Shang Wedged iron is cross
Component, lower plane are the inclined surface 1:30, and two inclined-planes reversely match, and plane is parallel with base end face on Wedged iron in guarantee, and makes ten
Wedged iron can up and down direction sliding along card slot Shang , in the horizontal card slot on the both sides insertion pedestal top of word.
In pedestal bed body center He Shang Wedged iron center is provided with circular through hole, Wedged iron glide direction center Xia
Position is provided with oblong through-hole, and three holes provide for cement column foot pre-embedded bolt across space, and oblong through-hole is sliding for lower Wedged iron
It is dynamic that there are enough leeway.Fig. 2 and Fig. 3 is two levelling device according to magnitude of load different designs, and principle is identical.
After column foot has been built and met the requirements, when equipment marches into the arena preparation lifting antenna pedestal, firstly, according at the top of column foot
The quantity of pre-embedded bolt, circumferentially by levelling device, one-to-one correspondence are mounted on column foot top surface, then successively lift day
The structure members such as line seat, after waiting the whole frame of antenna structure systems to be installed, so that it may horizontal to antenna pedestal deep bid by levelling device
Degree is adjusted.
Combined diagram level is placed on the inspection surface of antenna pedestal turntable, several circles in rotary antenna orientation, observation level meter is read
Number variation, determines the highs and lows of circumferential plane, then increases the principle that high point reduces according to low spot, utilizes leveling machine
Structure is adjusted it, until meeting.
Levelling principle are as follows: the nut of dextrorotation rotating base one end, due to the effect of drift double inclined plane, levelling device height increases
Add, i.e., rises antenna pedestal；The nut of left-handed rotating base one end, due to the effect of drift double inclined plane, levelling device height subtracts
It is small, i.e., antenna pedestal is reduced.I.e. by adjusting the relative position of a pair of of drift horizontal plane repeatedly, make drift in the ruler of vertical direction
It is very little to increase or reduce, to realize antenna pedestal turntable horizontal plane adjustment function.
The levelling device for putting into engineer application both at home and abroad at present, almost all uses traditional drift form.
But this traditional drift form has the following problems:
1, cement column foot top surface is built difficult
Antenna structure system belongs to high-accuracy mechanical equipment, requires the verticality of azimuth axis in rad magnitude, folding
Calculating is antenna deep bid elevation of water error in submillimeter rank, and antenna structure system be all installation set up with concrete pedestal it
On, and the construction precision of concrete pedestal routine is in a centimetre rank, basic built-in fitting is all loose mail in addition, to meet submillimeter
The horizontal error of rank almost cannot achieve, and to require to realize by force, then construction cost can be multiplied.
Typically, it although requirement is very high, and actually cannot achieve, tested through passing through frequently with received mode of giving way
It receives, as a result brings very big difficulty to subsequent leveling antenna pedestal.
2, levelling device adjustment is difficult
Levelling device adjustment is difficult, and key reaction is at two aspects:
First, multiple sliding friction pairs, frictional resistance are especially big.
Since levelling device supports the weight of entire antenna structure system, the secondary normal pressure of each friction is very big.Friction
Pair has: 1) nut and screw rod；2) nut and pedestal；3) Xia Wedged iron and pedestal；4) the Xia Shang Wedged iron of Wedged iron Yu；5) Xia Wedged iron and pedestal
Protect edge；6) Shang Wedged iron and pedestal card slot.
Second, effective travel is small, manually adjust extremely difficult.
Xia Shang Wedged iron faying face of Wedged iron Yu is the inclined surface 1:30, that is to say, that horizontal in every 1 millimeter of the raising of vertical direction
Direction will move 30 millimeters, 2 millimeters of screw rod lead, convert into nut rotation 15 circle.Since resistance is especially big and operating space limitation, pull
Dynamic 1 circle of nut rotation, needs replacing 5 to 6 wrench positions.I.e. in every 1 millimeter of the raising of vertical direction, need replacing 75 to 90 times
Wrench position.
If now descending Wedged iron screw thread axially bored line and nut mounting hole axis concentricity overproof out when processing, frictional resistance can be more
Greatly, this phenomenon often occurs in engineering again.
3, levelling device adjusting range is too small
Since basic built-in fitting horizontal error is very big (usual 3 to 8 millimeters), and the adjusting range of levelling device adjustment only has
± 1 millimeter, engineering site makes up the deficiency of adjusting range frequently with the method for increasing backing plate.
4, plane is not bonded on levelling device
Since basic built-in fitting horizontal error is very big, thus not in the presence of plane on a levelling device and antenna pedestal bottom surface
The problem of fitting, after causing antenna pedestal leveling to meet the requirements, horizontal error increases in a short time, exceeds index request, and needs weight
New adjustment.The point (line) between antenna pedestal bottom surface and basis, which contacts, simultaneously also generates more the overall stiffness of antenna structure system
Detrimental effect.
