Fill steel structural embedded parts.
Technical solution adopted by the utility model to solve its technical problems is：A kind of high ferro change rail track installation steel knot
Structure built-in fitting, is fixed with concreting, including steel plate ontology, and the steel plate ontology is equipped with uniform as the center of circle using steel plate center
The mounting hole being distributed in same radius circular, the mounting hole is interior, and there is plugged and fixed to have anchor rib, the anchor rib
It is fixed on steel plate ontology by mounting hole and there is the hook part being located at below steel plate ontology, the anchor rib to expose to steel
The top of plate body upper surface has external screw thread；The steel plate body surface integrally formed with mounting hole institute at circular shape concentric
Hollow steel column, bearing is fixed in the hollow steel column, the bearing inner wall key connection has rotation steel shaft.
Further, can be the internal annulus steel with through-hole by steel plate body design according to the design requirement of built-in fitting
Plate, the circular shape concentric that the ring steel plate is formed with mounting hole.
Further, bearing is self-aligning ball bearing, and there is the self-aligning ball bearing inner wall key, rotation steel shaft surface then to have
With the keyway of key cooperation.Self-aligning ball bearing has aligning function.When axis, shell are bent, can not be increased with adjust automatically
Bearing is born, and self-aligning ball bearing radial load ability is big, suitable for there is the case where heavy load, impact load.When rotation steel shaft
Top connect rail changing device component stress when, can adjust automatically, reduce impact, keep rotation it is smooth.
The utility model has the beneficial effects that high ferro change rail provided by the utility model is pre-buried with track installation steel construction
Part designs bearing and the key connection rotation steel shaft in bearing on steel plate ontology, when built-in fitting is connect with top rail changing device,
The component that can will likely be rotated or reverse is connect with rotation steel shaft, and power is unloaded with bearing fit rotation by rotating steel shaft,
Reduce the impact to built-in fitting, effectively improve the stability and service life of built-in fitting, reduces when top becomes rail to built-in fitting sheet
Body has an impact.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model optimum embodiment.
Fig. 2 is the sectional view of A-A in the utility model.
1 in figure, steel plate ontology 2, mounting hole 3, anchor rib 4, hook part 5, external screw thread 6, hollow steel column 7, bearing
8, steel shaft is rotated.
Specific implementation mode
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
A kind of high ferro as depicted in figs. 1 and 2 becomes rail track installation steel structural embedded parts, is the optimal reality of the utility model
Example is applied, built-in fitting is fixed with concreting, including steel plate ontology 1., can be according to the design requirement of built-in fitting in design, it will
Steel plate ontology 1 is designed as the internal ring steel plate with through-hole.
Steel plate ontology 1 is equipped with is evenly spaced on the mounting hole 2 in same radius circular as the center of circle using steel plate center.
The circle that mounting hole 2 is formed is concentric with the center of circle of ring steel plate.In actual design, can design has 12 on steel plate ontology 1
Mounting hole 2.Correspondingly, the angle between two neighboring mounting hole 2 and circle center line connecting is 30 °.There is plugged and fixed in mounting hole 2
There are anchor rib 3, anchor rib 3 to be fixed on steel plate ontology 1 and with the hook part for being located at 1 lower section of steel plate ontology by mounting hole 2
4, the top that the anchor rib 3 exposes to 1 upper surface of steel plate ontology has external screw thread 5.
1 surface of steel plate ontology integrally formed with mounting hole 2 at circular shape concentric hollow steel column 6, the hollow steel column 6
It is inside fixed with bearing 7,7 inner wall of bearing key connection has rotation steel shaft 8.Bearing 7 is self-aligning ball bearing 7, the spherical ball axis
Holding 7 inner walls, there is key, 8 surface of rotation steel shaft then to have the keyway coordinated with key.Self-aligning ball bearing 7 has aligning function.Axis,
It when shell is bent, can not increase by 7 burden of bearing, and 7 radial load ability of self-aligning ball bearing is big with adjust automatically, be applicable in
In there is the case where heavy load, impact load.When rotating the top of steel shaft 8 connection rail changing device component stress, can adjust automatically, subtract
Small impact keeps rotation smooth.
When mounted, anchor rib 3 is plugged on steel plate ontology 1 and is welded and fixed by mounting hole 2, will then rotate steel
Axis 8 is keyed in bearing 7.According to installation requirements, steel shaft 8 and the rotation section in the rail changing device of change rail rail inferior portion will be rotated
Part passes through mechanical means stable connection.At work, when track needs to become rail, electrical system manipulates orbit rotation and becomes rail, when
When orbit rotation, the rotatable parts of rail changing device rotate, and movement means rotate steel shaft 8 and rotate, movement means rotation
When steel shaft 8 generates part distortion, then by 7 adjust automatically of self-aligning ball bearing, the stabilization of built-in fitting entirety is maintained, is assisting to become rail
The stability and service life of built-in fitting are also improved simultaneously.
The high ferro so designed becomes rail track installation steel structural embedded parts, bearing 7 is designed on steel plate ontology 1 and in axis
Holding key connection rotation steel shaft 8 in 7 can will likely rotate or reverse when built-in fitting is connect with top rail changing device
Component is connect with rotation steel shaft 8, is unloaded power with the cooperation rotation of bearing 7 by rotating steel shaft 8, is reduced the impact to built-in fitting, effectively
The stability and service life of built-in fitting are improved, reduces when top becomes rail and embedded part body is had an impact.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to which its technology is determined according to right
Property range.
