Abstract
The utility model relates to an improved rotary platform supporter for satellite signal mobile receiving and automatic tracking antenna, which is characterized in that: the periphery of a support frame is provided with a plurality of support feet which stretch outwards and upwarp; shock absorbers are arranged on the lower side of the upwarping support feet so as to cancel the height increase of the rotary platform caused by the increase of the shock absorbers, meeting the requirements for the receiving antenna height of some moving carriers having special requirement for height limit, such as trains and automobiles.
Description
Technical field
Utility model is the improvement that receives automatic tracking antenna revolving dial bracing or strutting arrangement about satellite-signal is moved, and relates in particular to the vibration damping that can significantly reduce the antenna whole height every towards bracing or strutting arrangement.
Background technology
Satellite-signal (as radio, film and television) moves and receives automatic tracking antenna owing to be installed on the mobile vehicle, mobile vehicle can produce various mechanical oscillation in moving process, especially vibrate and impact, accurately normal tracking that influences antenna receives, and serious meeting causes antenna to damage because of machine shakes.Be installed in the stability of the reception antenna on the mobile vehicle for guarantee, minimizing is because of vibration and impact the harmful effect that causes the antenna generation, improve portable antenna tracking stability and functional reliability, a kind of solution is below the bracing frame of supporting antenna revolving dial vibration isolator to be set, vibration damping by vibration isolator is every dashing, to reduce the vibration that produces in the mobile vehicle moving process and to impact the harmful effect that tracking antenna is produced.Yet the bracing frame bottom installs vibration isolator additional, can cause the increase of entire antenna height usually again, and this makes troubles as train, automobile carrier band for some specific limit for height use occasion, also is unallowed.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of simple in structure, and effectively vibration damping does not increase the revolving dial bracing or strutting arrangement of antenna complete machine height again every dashing.
The utility model purpose realizes, the main improvement is to change plate bracing frame into stretch out feet with some bracing frame, and feet upwarped bending, vibration isolator is installed in upwarps bending feet downside, the bracing frame supporting plane is descended, thereby offset the height that increases because of mounting dampers, both reaching, vibration damping does not increase height again every dashing.Specifically, utility model revolving dial bracing or strutting arrangement is made up of bracing frame and the vibration isolator that is installed in downside, it is characterized in that said bracing frame has some outwardly directed feets, said feet upwarps bending, and said vibration isolator is installed in and upwarps bending feet downside.
Utility model is adjusted feet and is upwarped bending height according to vibration isolator height and required reduction requirement for height, can satisfy required reduction requirement for height.
Utility model is effectively to eliminate vibration and the impact of mobile vehicle from X, Y, three directions of Z, and said vibration isolator is excellent to adopt wire rope damper especially.
The said overhanging feet of utility model, especially to adopt cross structure, promptly bracing frame week side be provided with four of being cross structure and stretch out feet, both simple in structure, reliable and stable again.Make and the further height that reduces for convenient, said feet divides body structure to adopt with bracing frame especially, the feet that is about to bending is fixed on the bracing frame by screw, and make connection bend the bracing frame position indent of feet, enough intensity and stiffness can be guaranteed like this, height can be further suitably reduced simultaneously again.
Utility model is owing to adopt band to stretch out the bracing frame of pin, and feet upwarped bending, vibration isolator is arranged on the feet downside that upwarps bending, this structure not only can effectively be offset because of adding vibration isolator increases height, upwarp bending height but also can stretch out pin by adjustment, fully reduce bracing frame bearing-surface height, thereby satisfy some specific mobile vehicle to the requirement of portable antenna limit for height, low simultaneously antenna also helps and reduces resistance in the moving process, improves the stability of antenna system on mobile vehicle.Secondly, this structure not only effectively reduces the antenna whole height, but also makes supported body-antenna center of gravity descend, and has effectively reduced two centroidal distances of supported body and vibration insulating system, makes the vibrationproof flushing partiting effect be better than the common plane lower support greatly.Wire rope damper can be simultaneously to three direction Vibrant buffers, and the vibrationproof flushing partiting effect is good, and the mobile receiver aerial fluctuation amplitude is little, helps mobile accurate tracking.
Description of drawings
Fig. 1 is a kind of preferred embodiment structural representation of utility model.
Fig. 2 is Fig. 1 plan structure schematic diagram.
Embodiment
Embodiment: referring to accompanying drawing, utility model moves and receives automatic tracking antenna revolving dial bracing or strutting arrangement, includes to be the bracing frame 3 that cross stretches out pin, and pin 2 is stretched out in the bending that upwarps that is connected with split, and stretching out the underfooting side is wire rope damper 1.Bracing frame connects and to upwarp bending and stretch out the foot position one indent platform is arranged, and is revolving dial 4 on the bracing frame support platform.
The utility model bracing or strutting arrangement also can adopt other to stretch out leg structure, and upwarp form, and other forms of vibration isolator, belongs to the utility model protection scope equally.
Claims (5)
1, a kind of revolving dial bracing or strutting arrangement is made up of bracing frame and the vibration isolator that is installed in downside, it is characterized in that said bracing frame has some outwardly directed feets, and said feet upwarps bending, and said vibration isolator is installed in and upwarps bending feet downside.
2,, it is characterized in that said bracing frame stretches out pin and is cross according to the described revolving dial bracing or strutting arrangement of claim 1.
