Slotted waveguide antenna fixed support peptizaiton in the present embodiment is in horizontal and vertical on slotted waveguide antenna
The principle of stress be：Cause waveguide when serious phenomenon of expanding with heat and contract with cold occurs for slotted waveguide antenna (i.e. transverse direction) no vertically
During disconnected stretching, extension, the crossed strip of support member side shrinks, the spring stretching, extension of opposite side, so as to which the stress buffer of transverse direction be fallen；
When slotted waveguide antenna is by vertical pressure, (such as personnel trample, and object falls, and subway high-speed passes through caused blast
Deng), stress is separated into a face by buffer substrate tablet first, and subsequent longitudinal spring shrinks, and stress is buffered.Treat that stress buffer is complete
Bi Hou, spring are adjusted waveguide to original position by the effect of restoring force.
The effect of embodiment and effect
The slotted waveguide antenna fixed support provided according to the present embodiment, due to adding on the basis of existing technology
Longitudinal stress buffer part so that the fixed support can simultaneously fracture radiating guide by transverse direction stress and longitudinal direction stress
Enter row buffering, the support of fixing crack radiating guide is pushed away after accumulation after a while so as to effectively prevent the power of stretching, extension
Situation occurs, and then is advantageous to the communication system of orbit keeping traffic and the traffic safety of train.
Further, since containing the design of metal spring and Novel anti-ageing rubber in longitudinal stress buffer part, work as generation
During pressure at right angle (such as personnel trample, and object falls, and subway high-speed passes through caused blast etc.), spring enables to waveguide
Not because rigid support causes to destroy, stress is effectively shared, and at the end of stress, reduction waveguide to original position.Spring
The anti-aging rubber of top docking, improves effective Area of bearing of waveguide mount, can be effectively dispersed in steel flange position
Concentrated stress, waveguide is played a protective role, and then improve security of the crack waveguide tube in metro environment and can
By property.
Further, since further comprises height adjusting unit in longitudinal stress buffer part, need to only be adjusted by rotation height single
The i.e. adjustable support bracket fastened height in ground of member, regulative mode are convenient and swift.
In addition, hollow metal sheath is welded on the fixed mount nut of ground, convenient overlap joint regulation crossbeam.And hollow metal is protected
Set is mutually fixed by screw with the end for penetrating crossbeam therein, changes the support for only relying on frictional force support in the prior art
Mode, structural support are more preferable.Simultaneously because excessive screw need not be installed so that the installation of waveguide tube fixing support is more
It is convenient and swift, reduce engineering time and workload.
