Description
Technical field
The utility model relates to railway traffic equipment, especially a kind of track line switch area frog structure.
Background technique
Track switch is the line connection equipment that rolling stock was transferred to or crossed another station track from a station track, is the weight of track structure
Want component part.Currently, applying in railway and urban track traffic at most is common single turnout, it is by railway switch, connection
Partially, three unit compositions of railway frog and guard rail.Railway frog is the equipment for instigating wheel to cross another strand of rail by one rail, by pitching
The heart, wing rail and union piece composition.By structural type point, there is two class of stiff frog and swing nose crossing.
For stiff frog, frog centre and wing rail are fixed, therefore in structure more than swing nose crossing
Add solid and reliable.But it is still there are some drawbacks, and being mainly manifested in from throat of frog to fork apex of the heart end has one section of path
The distance of interruption, that is, the idle space of track switch.On the one hand, wheel by herein when, it is possible to because hit fork apex of the heart end or
It goes to the wrong way frog flangeway and causes to derail；On the other hand, the presence of idle space also limits the switch crossing speed of train, to start high speed
Train is very unfavorable.
For movable-point crossing, although its idle space for having eliminated track switch, make driving more it is steady pleasantly.But
It still comes with some shortcomings, on the one hand, movable-point crossing is by parts groups such as wing rail, long heart rail, short heart rail, fork tip of a root rails
It closes, construction is more complicated, and processing is laid with particularly inconvenient；On the other hand, movable-point crossing occupied space is larger, at certain
A little limited areas of landform are not applicable.
Summary of the invention
The purpose of this utility model is just to provide a kind of simple structure, laying easy to process, maintenance, can eliminate having for track switch
Evil space and the space occupied for reducing railway frog make the more steady track line switch area frog structure pleasantly of driving.
The track line switch area frog structure of the utility model, including railway frog main body, left fork apex of the heart rail, the right fork apex of the heart
Rail, hydraulic pressure lifting device, which is characterized in that the middle part of railway frog main body is equipped with the cavity of upper end opening, left fork apex of the heart rail, the right fork apex of the heart
Rail is placed in the cavity in the middle part of railway frog main body, and left fork apex of the heart rail lower end is equipped with left front hydraulic pressure lifting device, left back hydraulic lifting
Device, right fork apex of the heart rail lower end is equipped with hydraulic pressure lifting device behind hydraulic pressure lifting device, the right side before the right side, and hydraulic pressure lifting device is for raising or lowering
The height of left and right fork apex of the heart rail；The working signal of hydraulic pressure lifting device is controlled by switch machine；It opens respectively the front and back end of railway frog main body
There are a preceding anchor hole, rear anchor hole, preceding anchor bolt, rear anchor bolt are each passed through preceding anchor hole, rear anchor hole for railway frog main body
It is fixed on left wing's rail, stiff frog throat that right flank rail is constituted is to the path interrupting portion between frog centre tip.
The track line switch area frog structure working principle of the utility model is as follows, by taking double turnout as an example, works as locomotive
Vehicle is intended being transferred to left side to station track when driving, and signal center will manipulate left front rear hydraulic pressure lifting device automatically reduces left fork apex of the heart rail
Highly, make its upper surface lower than train wheel rim, to open left side to frog flangeway, for train passage, while it is hydraulic to manipulate right front and back
Lifter is lifted right fork apex of the heart rail height, its upper surface is made to be flush with right flank rail and frog centre surface, on the right side of closing to
Frog flangeway prevents train passage, while guiding train along left side to traveling.In this way, just open left side to station track, close
Right side is to station track.When rolling stock is intended being transferred to right side to station track when driving, it is hydraulic that signal center will manipulate automatically right front and back
Lifter reduces right fork apex of the heart rail height, leads to its upper surface to open right side to frog flangeway for train lower than train wheel rim
Row, while manipulating left front rear hydraulic pressure lifting device and being lifted left fork apex of the heart rail height, make its upper surface and left wing's rail and frog centre surface
It is flush, train passage is prevented to frog flangeway to close left side, while guiding train along right side to traveling, in this way, just
Left side is closed to station track, has opened right side to station track.
The track line switch area frog structure of the utility model, in stiff frog throat to the rail between frog centre tip
Line interrupting portion installs a Full-automatic hydraulic tongue lifting apparatus, passes through the height centering of two fork apex of the heart rail of control left and right
Disconnected position is filled a vacancy, so that path is continuous, not only eliminates the idle space of track switch, make driving more it is steady pleasantly, also contract
The small space occupied of railway frog has stronger applicability, in addition, the novel frog also has, structure is simple, paving easy to process
If, maintenance it is easy to change the advantages that.
