Description
Technical field
The utility model is related to a kind of long slab bridges.
Background technology
Long slab bridge is the turning member of long slab, connects the critical component of plate face and wheel, there is formal dress and anti-dress two ways,
It mainly includes pedestal, main bridge nail and hanging rod, however existing long slab bridge is supported by individually main bridge nail, works as extension
When bar has lateral movement trend or deflection, hanging rod easily generates laterally offset with pedestal, in view of this, it is necessary to which design is a kind of steady
Qualitative higher long slab bridge.
Utility model content
The technical issues of the utility model solves is to provide a kind of long slab bridge, to solve lacking in above-mentioned background technology
Point.
The technical issues of the utility model solves is realized using following technical scheme：
A kind of long slab bridge is followed closely including hanging rod, pedestal, axostylus axostyle and main bridge, and pedestal is followed closely equipped with main bridge, the both sides difference of hanging rod
Equipped with axostylus axostyle, hanging rod upper end is equipped with pagoda of bowls axis, and pagoda of bowls the tip of the axis is mounted on through vertex bowl in the axis hole of pedestal, the centre of hanging rod
Equipped with PU slots and main bridge nail hole, pedestal is followed closely by main bridge across main bridge Bolt-hole fits PU bearings and main bridge nail nut to be connected with hanging rod
It connects, the lower section that main bridge nail is located on pedestal is equipped with secondary bridge nail, and the lower section of PU slots is equipped with bearing seat slot, bulb is equipped in bearing seat slot
Bearing block and secondary bridge oncomelania line, pedestal are followed closely across secondary bridge oncomelania line matching pair bridge nail nut by secondary bridge and are connect with hanging rod.
Further, secondary bridge nail and bulb bearing saddle bore clearance fit.
Further, the central axis of PU slots and the centerline axis parallel of bearing seat slot.
Further, the axis of secondary bridge oncomelania pit is parallel with the axis of main bridge oncomelania pit.
Further, the material of PU bearings is polyurethane.
Compared with prior art, advantage is apparent for the utility model, reasonable in design, safety, is hanging rod by secondary bridge nail
Additional restraining force is provided, the stability of hanging rod can be effectively increased, greatly improves long slab bridge overall stability.
Description of the drawings
Fig. 1 is the structure chart of the preferred embodiment of the utility model；
Fig. 2 is the sectional side view of the utility model；
In figure, hanging rod 1, pedestal 2, axostylus axostyle 3, main bridge nail 4, secondary bridge nail 5, vertex bowl 6, main bridge nail nut 7, PU slots 8, PU axis
Hold 9, bearing seat slot 10, bulb bearing block 11.
Specific embodiment
In order to be easy to understand technical means, creative features, achievable purpose and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Embodiment 1, referring to Fig. 1 and Fig. 2, a kind of long slab bridge, including hanging rod 1, pedestal 2, axostylus axostyle 3 and main bridge nail 4, pedestal 2
It is equipped with main bridge and follows closely 4, the both sides of hanging rod 1 are respectively provided with axostylus axostyle 3, and 1 upper end of hanging rod is equipped with pagoda of bowls axis, and pagoda of bowls the tip of the axis is through vertex
Bowl 6 is mounted in the axis hole of pedestal 2, and the centre of hanging rod 1 is equipped with PU slots 8 and main bridge nail hole, and pedestal 2 passes through master by main bridge nail 4
Bridge Bolt-hole fits PU bearings 9 and main bridge nail nut 7 are connect with hanging rod 1, and the material of PU bearings 9 is polyurethane, is located at master on pedestal 2
The lower section of bridge nail 4 is equipped with secondary bridge and follows closely the lower section of 5, PU slots 8 equipped with bearing seat slot 10, central axis and the bearing seat slot 10 of PU slots 8
Centerline axis parallel, be equipped with bulb bearing block 11 and secondary bridge oncomelania line in bearing seat slot 10, the axis of secondary bridge oncomelania pit with
The axis of main bridge oncomelania pit is parallel, pedestal 2 by secondary bridge nail 5 pass through secondary bridge oncomelania line matching pair bridge nail nut again with hanging rod
1 connection, secondary bridge nail 5 and bulb bearing saddle bore clearance fit.
It is worth noting that the utility model, by the way that secondary bridge is set to follow closely, when hanging rod 1 has lateral movement trend, secondary bridge follows closely 5
Support is provided to hanging rod, laterally offset is eliminated and improves stability, when hanging rod deflects, secondary bridge follows closely 5 pairs of hanging rods and provides lateral support,
Hanging rod is made to be not susceptible to laterally offset, so as to improve stability.Compared with prior art, advantage is apparent for the utility model, structure
Reasonable design, safety provide additional restraining force for hanging rod by secondary bridge nail, can be effectively increased the stability of hanging rod, greatly
Improve long slab bridge overall stability.
The basic principle of the utility model and main feature and the advantages of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
