Abstract
The utility model discloses a bogie antenna mounting seat which aims to solve the problem that an existing antenna mounting seat is prone to crack in advance due to fatigue. The bogie antenna mounting seat comprises a support and a hanging seat, wherein the support is installed on a beam in the middle of a framework, and the hanging seat is used for installing antennae and fixedly connected with the support. The antenna mounting seat is installed on the beam in the middle of the framework, vibration and inertia force are greatly reduced, risks of occurrence of fatigue cracks to welding joints and base materials are reduced, and the service life of the bogie antenna mounting seat is prolonged.
Description
Technical field
The utility model relates to rail traffic vehicles bogie truck antenna installing area, is specially a kind of bogie truck antenna mounting seat.
Background technology
Current bogie truck ATC(Automatic Train Control) antenna mounting seat mainly designs on the end carriage of framework, and the mode be connected with framework by end carriage mainly is divided into and is rigidly connected and flexibly connects.For being rigidly connected, because end carriage bears larger vibratory impulse and torsional deflection, the fatigue cracking problem easily appears; For flexibly connecting, easily cause end crossbeam self rigidity deficiency, resonance occurs and produces endurance crack in easy and framework.
Chinese patent CN201020197829.2 discloses a kind of ATC mounting beam for metro bogie, it comprises that cover plate, reinforced rib, adapter plate assembly welding become support, crossbeam solid drawn pipe, antenna bracket, transition seat assembly welding become the ATC hanging beam, and support and ATC hanging beam are bolted and form the ATC mounting rail; This ATC mounting beam for metro bogie is mainly to form by support and ATC hanging beam, is arranged on the framework end, also has the problems referred to above.
The utility model content
For the antenna mounting seat overcome on existing bogie truck bears than force of inertia and the vibratory impulse power of large traction, generation while braking, the deficiency of fatigue cracking easily appears in mother metal, weld seam or bolt in advance, the utility model aims to provide a kind of bogie truck antenna mounting seat, this antenna mounting seat is contained on the crossbeam at framework middle part, can greatly reduce vibration and force of inertia, reduce the risk that endurance crack appears in weld seam and mother metal.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of bogie truck antenna mounting seat, its constructional feature is that it comprises
One support, it is contained on the crossbeam at framework middle part;
One flap seat, for fixing up an aerial wire, this flap seat and described support are fixedly linked.
Be below the technical scheme of further improvement of the utility model:
In order to regulate the cantilever span of flap seat, between described support and flap seat, pad is housed.
As a kind of specific constructive form of flap seat, described flap seat comprises the riser be connected with support and the transverse slat be connected with riser, and flap seat integral body is L-shaped; Be provided with a plurality of mounting holes that fix up an aerial wire on described transverse slat.
In order to strengthen the structural strength of flap seat, be provided with at least one strengthening rib between described riser and transverse slat.
For easy disassembly flap seat and the adjustment of ATC antenna distance rail level setting height(from bottom), described flap seat and described support removably link together by bolt and nut, have the waist shaped hole of being convenient to adjust distance between antenna and rail level on this flap seat.
As a kind of concrete version of support, described support overall U-shaped, consider to have carried out optimal design from expendable weight, and apply impact load by the ANSYS finite element and calculate and be optimized design.
In order to strengthen the Joint strenght of support, be provided with at least one floor between described support and crossbeam.
Described antenna is preferably the ATC antenna.
By said structure, the installation ATC antenna of take is example, the utility model designs bogie truck ATC antenna mounting seat on the framework middle beam, typical structure is as Fig. 1, crossbeam 1 two ends follow the framework middle part to connect by welding, and support 2 follows crossbeam 1 to connect by welding, and flap seat 4 is connected with support 2 by bolt, pad 3, the ATC antenna is arranged on flap seat 4 belows by bolt, realizes that ATC installs.Near framework central region bogie truck vibration less, ATC is arranged on middle beam and structure is optimized to design simultaneously, can greatly reduce vibration and force of inertia, reduce the risk that endurance crack appears in weld seam and mother metal.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, and reasonable stress has reduced stress and concentrated; Be arranged on middle beam, greatly reduce vibration and force of inertia, reduced the risk that endurance crack appears in weld seam and mother metal, extended the service life of bogie truck antenna mounting seat, be particularly useful for the installation of ATC antenna.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
The accompanying drawing explanation
Fig. 1 is the structure principle chart of an embodiment of the utility model.
In the drawings
The 1-crossbeam; The 2-support; The 3-pad; The 4-flap seat; The 5-riser;
