Description
Technical field
The utility model relates to empty rail road fashioned iron technical fields, more particularly to a kind of empty rail road fashioned iron.
Background technique
Empty iron is suspended from a kind of rail vehicle run on overhead rail, as a kind of light-duty, middling speed, middle freight volume it is new
Type public transport mode is integration, multi-mode, the necessary component of three-dimensional public transport system.
China is vast in territory, and the environmental factor of diverse geographic location differs greatly, therefore is directed to the empty iron Track desigh in China,
To guarantee that overhead rail has reliable bearing capacity in certain time limit, need to consider the wearability of empty iron rail material and resistance to
Corrosive nature etc..In the prior art, the area good for some weather conditions, ambient humidity is little, the material being exposed to the atmosphere
Material is not easily susceptible to corrode, it is contemplated that non-weather-proof steel material can be used in the material cost problem of overhead rail, is using non-weatherability
When the steel of material, it is desirable that the more common Q345B of its corrosion resistance is suitable.
In the prior art, a kind of significant design form of the empty rail road middle orbit beam in China be include track panel and upper
Framework, the two sides of upper frame body are guide panel, and the guide surface of directive wheel is located at the inside of track panel, rail on empty iron power pendant
Supporting surface of the pavement slab as traveling wheel on power pendant.In view of material utilization amount and track girder weight, in-orbit pavement slab design
When, generally using and being set as track panel includes for traveling wheel providing the walking panel of walking surface and as walking surface board bottom portion
Play the ribs of bending resistance booster action.Although being directed to the specifically used position of track girder, used under corrosive atmosphere environment
Raw material of the resistant material as track panel, but walk panel and ribs in the welding process caused by sweating heat meeting
The material property for influencing heat-affected zone, causes the corrosion resistance in heat-affected zone to decline to a great extent compared to other regions.
Utility model content
Although being used under corrosive atmosphere environment for the specifically used position set forth above for track girder
Raw material of the resistant material as track panel, but generated sweating heat can shadow in the welding process with ribs for panel of walking
The material property for ringing heat-affected zone, causes the corrosion resistance in heat-affected zone to be asked compared to what other regions were declined to a great extent
Topic, the utility model provide a kind of empty rail road fashioned iron, this fashioned iron can effectively improve the corrosion resistance of gained track girder,
The structure design of this fashioned iron is conducive to be promoted the producing efficiency of track girder simultaneously.
The technological means of this programme is as follows, a kind of sky rail road fashioned iron, including walking panel and is set to walking panel
The ribs of lower section, both the walking panel and ribs are connected, and to be formed by connector be to form or pass through forging by casting
Overall structure made of making.
Specifically, being formed by connector in the present solution, being connected by both will walk panel and ribs to pass through casting
It makes and forms or pass through overall structure made of forging, i.e., the described connector is an overall structure, which passes through casting
Or it forges and obtains, and there is walking panel and ribs in the overall structure.In this way, this programme is compared to the prior art, we
When case is assembled for track girder, the twice weld seam for eliminating ribs first between panel of walking is conducive to promote track girder
Producing efficiency；Simultaneously as no-welding-seam between ribs and walking panel, therefore can effectively avoid sweating heat to track girder material
It is influenced caused by performance, and in the prior art, corresponding twice weld seam is inherently located in the regional scope of compression, therefore this programme
Corrosion resistance, the mechanical property reliability of track girder can effectively be promoted.
Further technical solution is：
When to avoid the traveling wheel of sky iron from acting on the side of ribs, ribs is answered with the walking panel region that connects
The service life of track girder is concentrated and influenced to power, and each side of the ribs and the bottom surface of walking panel pass through the first rounding
Face connects transition.In the present solution, above first rounded surface is the smooth-sided compression candles of the bottom surface and ribs for realizing walking panel
Excessively.
As the specific implementation of the first rounded surface, the radius of curvature of first rounded surface between R8 between R12,
First rounded surface include first to connect with reinforcing rib sides connect region, connect with the second of walking surface plate bottom connection
The transitional region that region, the region that connects positioned at first connect between region with second, described second connects region and transitional region
It is respectively positioned on the outside of ribs.In the present solution, can be effective relative to the position restriction of reinforcing rib sides to above first rounded surface
Avoid the material of the first rounded surface position local stress when track girder uses excessive.
Since track girder generally further includes guide panel, to avoid opening up welding when walking and welding guide panel on panel
Groove, it is described walking panel upper surface on be additionally provided with fitting groove in a strip shape, the length direction of the fitting groove is parallel to
The length direction of walking panel, and one end of fitting groove is intersected with one end of walking panel, the other end and walking surface of fitting groove
The other end of plate intersects, and the fitting groove is located at the side of ribs.In the present solution, setting wide for the width of the fitting groove
It, can side and fitting groove after the lower end of guide panel is embedded in fitting groove, in guide panel in the thickness of guide panel
Gap is obtained between groove face as welding groove.
Due to the bottom tension of this track girder ribs when in use, to avoid the corner on the downside of ribs because being damaged
Hurt and stress concentration occur, finally causes the service life and reliability that crack and influence track girder on ribs, it is described
The two sides of ribs and the bottom surface of ribs pass through the second rounded surface and connect transition.
The utility model has the advantages that：
In the present solution, be connected by both will walk panel and ribs be formed by connector to form by casting or
By overall structure made of forging, i.e., the described connector is an overall structure, and the overall structure is by casting or forging
, and there is walking panel and ribs in the overall structure.In this way, this programme is compared to the prior art, this programme is used for rail
When road beam assembles, the twice weld seam for eliminating ribs first between panel of walking is conducive to the production effect for promoting track girder
Rate reduces construction cost and shortens the construction period；Simultaneously as no-welding-seam between ribs and walking panel, therefore can effectively avoid weldering
Heat is connect on influence caused by track girder material property, simultaneously because eliminating thermal stress influence, can effectively ensure that the flat of walking surface
Whole degree, and in the prior art, corresponding twice weld seam is inherently located in the regional scope of compression, therefore this programme can be promoted effectively
Corrosion resistance, the overall mechanical properties of track girder.
