Description
Technical field
The utility model belongs to track equipment technical field, and more particularly, it relate to a kind of improvement of track circuit shunting
Device.
Background technique
Currently, track circuit shunting badness just refer to track circuit rail level because bad conductive material influence cause train or
Car team controls track section track relay when occupying track cannot normally be fallen, and interlocking of signals is caused to fail.This may
Cause to handle train reception and departure or shunting route to the section for thering is vehicle to occupy, this is breakneck.Caused by serious consequence just
It is car accident.
Currently, due to track circuit shunting badness caused by accident be major safety risks throughout system-wide.It is true
On since having railway, this problem perplex always railway equipment maintenance department.Reason mainly has train number to cause rail to become rusty less
Sedimentating dust leads to poor contact between Rail Surface and Railway wheelset on rail under erosion and special geologic condition.
Specifically, track circuit shunting badness problem easily causes train operation work personnel to ignore track occupation, mention
Preceding unlock or route setting cause track switch incorrect rotation, cause train or car team to derail, squeeze trouble or tight to there is fare to pick up etc.
The generation of weight accident, is not only delayed train operation, upsets normal transport order, also seriously affects operating efficiency and economic effect
Benefit.
Track circuit shunting badness, be specifically reflected in driving room console on, when having vehicle occupancy, light belt is not red, track after
Electric appliance is not fallen, and person on duty can not confirm.It causes the accident.According to incompletely statistics, system-wide " shunting badness " region is no less than
At 100000/point.
The purpose of the utility model is to overcome the drawbacks described above of the prior art, have developed a kind of track circuit shunting improvement dress
It sets, equipped in the case of the track circuit shunting improved device, the device is just short by rail or so rail when locomotive enters monitoring section
It connects, residual voltage disappears, and track relay is reliably fallen, and eliminates " shunting badness " phenomenon.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, providing one kind can reliably eliminate that " branch is not
It is good " the track circuit shunting improved device of phenomenon.
The technical solution of the utility model is: a kind of track circuit shunting improved device comprising detection coil, induced electricity
Road and relay, wherein the detection coil by several cable rings at and there are fixed induction reactance, the both ends of the detection coil
It is connected respectively to the sensor circuit and forms resonant tank, the sensor circuit further connects the relay, the relay
The output end of device is connected between the left and right rail of rail using plug nail type respectively, and the sensor circuit includes sensor.
Further, the resonance frequency of the resonant tank sets a threshold value, the frequency that the detection coil detects
The output end of the relay is closed the left and right rail short circuit so that rail when more than the threshold value.
In conclusion the utility model has the beneficial effects that: the track circuit shunting improved device of the utility model is big
Transport production efficiency is improved greatly, and high safety and reliability greatly reduces the labor intensity of vehicle business producers, and work occurs in reduction
A possibility that making mistakes.
The utility model is described in more detail below by embodiment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the track circuit shunting improved device of the utility model.
Specific embodiment
The utility model is further described in a manner of embodiment combination attached drawing below.
As shown in Figure 1, it illustrates the track circuit shunting improved device of the utility model, track circuit shunting improvement
Device includes detection coil 1, sensor circuit 2 and relay 3, wherein the detection coil 1 by several cable rings at and have
Fixed induction reactance, the both ends of the detection coil 1 are connected respectively to the sensor circuit 2 and form resonant tank, the sensor circuit 2
The relay 3 is further connected, the output end of the relay 3 uses between the left rail 3 and right rail 4 of rail respectively
Plug nail type connection.
The resonance frequency of the resonant tank sets a threshold value, and the frequency that the detection coil 1 detects is more than the threshold
The output end of the relay 4 is closed so that short-circuit between the left rail 3 and right rail 4 of rail when value.
The track circuit shunting improved device of the utility model use metal detection principle, from principle exclude mud, water,
The influence to device such as ice, snow, nonmetallic house refuse, small size metal objects and animal.
The track circuit shunting improved device of the utility model includes detection coil 1 and sensor circuit 2, wherein detection coil
1 is core.Coil can generate magnetic field after being powered, and have newly-increased metallics to enter magnetic field, exactly cause changes of magnetic field, thus
Judgement has metallics.Periodically variable magnetic field generates eddy electric field in space.And eddy electric field is if encountering metal,
It will form eddy current, can be detected.
After detecting metal, the sensor in sensor circuit 2 starts output signal, and driving relay closure conducting is short
Road can send a signal to train control system after the closure conducting of relay 3, and train control system learns the steel after receiving signal
Rail section passes through with train.
The track circuit shunting improved device main structure body of the utility model is mounted on above sleeper, and the height of highest point is not
It can exceed that rail level height.Two plug pin lines are connected by the plug pin hole of 9.8mm with rail.If it is solar powered, then power
Equipment is mounted on outside side slope, must not invade limit.
The structure that the track circuit shunting improved device of the utility model is not limited to the above embodiments can carry out a variety of changes
Type.In short, being both fallen in the scope of the utility model in all improvement not departed within the scope of the spirit of the present invention.
