Abstract
The utility model discloses an antenna elevating tower, which is characterized in that a mast and a power drive are fixed on a base; two driving synchronous pulleys which can be respectively and independently opened and closed are arranged on a power shaft of the power drive; a corresponding driven pulley and a driving belt stretcher are fixed on the top end of the mast; one driving belt is fixedly connected with a guide frame which is provided with an antenna polarization pipe; a brake of the driving belt is arranged on the base; a rack is arranged on the other driving belt; and a gear engaged with the rack is arranged on the antenna polarization pipe capable of rotating around a central axis. When in use, the utility model can conveniently realize the antenna elevation and horizontal rotary polarization required during product electromagnetic compatibility test in an open testing field or an anechoic darkroom.
Description
Technical field
The utility model relates to the corollary equipment that electromagnetic compatibility test is used, specifically a kind of antenna automatic lifting tower that cooperates test.
Background technology
Along with the development of modern technologies, the particularly enhancing of people's environmental protection consciousness is more and more paid attention to the Electro Magnetic Compatibility of product.For the product of having included national compulsory product certification scope in, emc testing has become a kind ofly must survey project.And when using open checkout area or anechoic chamber to carry out the product emc testing, antenna needs vertical lift and horizontally rotates polarization, the load bearing equipment that does not have to realize the antenna lifting easily in the prior art and horizontally rotate polarization.
The utility model content
The purpose of this utility model just provides a kind of new antenna lifting tower, to realize the antenna lifting easily and to horizontally rotate polarization.
The utility model is achieved in that this lifting tower is to be fixed with mast and power and transmission device on base, two active synchronization belt wheels of self contained function separately are housed on the line shaft of transmission device, and the mast top is fixed with corresponding driven pulley and belt tensioner; Wherein a driving-belt is affixed with the leading truck that the antenna polarization device is installed, and the brake of this driving-belt is installed on the base; On another driving-belt tooth bar is installed, can on the antenna polarization pipe that central axis rotates, be equipped with and this tooth bar meshed gears.
When the utility model uses, antenna is loaded on the antenna polarization device.Opening power, power passes to line shaft by transmission device.When two active synchronization belt wheels start simultaneously and do when being synchronized with the movement, two driving-belts drive leading truck and take the antenna polarization pipe and together do vertical displacement movement.Start and the brake mechanism that the affixed driving-belt of antenna polarization leading truck is installed, can be locked in a certain height and position with the affixed leading truck of this driving-belt, at this moment, another affixed rack for transmission band still is in the movable state.Because leading truck is locked in certain altitude, and the tooth bar on the driving-belt still is in the motion that can rise or descend, therefore, this rack drives and its meshed gears are around its central axis rotation, thereby drive the antenna polarization pipe that joins with it and do synchronous rotation, and then realize the polarization of the contained antenna of antenna polarization pipe.The direction of rotation of antenna polarization pipe depends on the direction of motion of tooth bar.Therefore, by the positive and negative rotation direction of control belt wheel, control the rising or the decline of tooth bar, thereby finish the horizontal polarization and the perpendicular polarization process of antenna.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the utility model structural representation.
Fig. 2 is the B-B cutaway view of Fig. 1.
Embodiment
As shown in Figure 1, this antenna lifting tower is to be fixed with mast 4 and power and transmission device 2 on base 1, and power passes on the power output shaft through the decelerator and the shaft coupling of transmission device 2, and power output shaft is connected to the two active synchronization belt wheels that can open and close respectively.This two belt wheel is connected on respectively on two power output shafts that can independently open and close separately.A kind of execution mode preferably is that two active synchronization belt wheels are connect same power output shaft altogether, and the driving pulley 22 that wherein connects driving-belt 5 joins by clutch 23 and power output shaft.Like this, by solenoidoperated cluthes 23, i.e. the keying of may command driving pulley 22.Mast 4 tops are fixed with corresponding driven pulley 6 and belt tensioner 7, and this part adopts structure of the prior art to get final product, and two driving-belts can adopt nonmetallic synchronous cog belt.Driving-belt 5 is affixed with leading truck 3, establishes the brake mechanism of this driving-belt 5 on base 1, this driving-belt can be locked in arbitrary height.This brake mechanism can adopt any one brake structure in the prior art, a kind of attainable mode is the brake 21 that is connected to this synchronous pulley 22 of may command on base 1, easily driving-belt 5 is locked, make leading truck 3 be locked in certain altitude by control belt wheel 22.Another driving-belt 11 is connected with tooth bar 13 by connecting plate 12.Can on the antenna polarization pipe 14 that central axis rotates, be connected to and tooth bar 13 meshed gears 10.
In the above-mentioned execution mode, in the time of need doing lifting action, release brake, driving pulley 22 and clutches engaged, power output shaft drives two synchronous pulleys and does rotation simultaneously, realizes rising or down maneuver.In the time of need doing antenna polarization, brake and belt wheel 22 engagements, throw-out-of clutch with belt wheel 22 brakings, thereby is locked in certain altitude with leading truck and antenna polarization pipe.Realize polarization by tooth bar 13 by driving the rotation of antenna polarization pipe with its meshed gears 10.
A kind of execution mode preferably is to be provided with the directive wheel 9 that moves along mast 4 on leading truck 3, stably rises or descending motion so that leading truck 3 is done.
Frictional force when reducing the rotation of antenna polarization pipe makes the relative position between itself and the leading truck fix simultaneously again, and a kind of execution mode preferably is the supporting friction ring 8 that is fixed with supporting antenna polarization pipe 14 on leading truck 3.
This antenna lifting tower can be all-electric, by computer-controlled operation, utilizes two nonmetallic synchronous cog belts to finish antenna lifting and polarization action respectively.
