Description
Affiliated technical field
The utility model relates to the controlled top of a kind of safety of railway traffic device, especially railway solenoid valve failure and isolates warning device automatically.
Background technology
At present, railway goods yard vehicle marshalling rolling operation has adopted Speed Control System of Controlled Retarder by Computers to carry out in a lot of stations section.The main composition and the principle of work of this system are: the potential energy that is utilized its gravity to produce from physical features higher " hump " by the vehicle of rolling carries out the inertia rolling along track to the physical features lower.Owing on the highway section of humping of cars, installed and measured car weight, the speed of a motor vehicle isoparametric sensor and utilized executive devices such as controlled top by solenoid control that (wheel was when pressing controlled top, stressed and the acting in controlled top, thereby vehicle is formed certain resistance, to underspeed), so, finally can be stopped by the vehicle of rolling generally speaking and go up in position, and can realize normally connecting extension.Yet due to multiple reason, the electromagnetic valve coil on controlled top is in when work, the time overload, short circuit are arranged or failure condition such as open circuit takes place, make by the controlled top cisco unity malfunction of control, directly influence promptly influences normally carrying out of vehicle marshalling work to by the control effect of skating vehicle.Particularly; in the Speed Control System of Controlled Retarder by Computers; be responsible for execution power supply circuit board (call in the following text and carry out power panel) and be mostly on its same output line and then tens tens electromagnetic valves at most at least to controlled top solenoid valve; this execution power panel has comparatively sensitive overload and short-circuit protection function simultaneously, interrupt voltage output rapidly when above-mentioned situation promptly occurring.Like this, when causing execution power panel to its power supply to produce protection in case the short circuit overload situations appears in some electromagnetic valve coils, other controlled top of then same power supply power supply also will be because of can not get the power supply interruption of work.Like this, just very easily caused the vehicle of just that the unsafe condition of " putting sheep out to pasture " takes place by rolling.Simultaneously, just because of more electromagnetic valve coil is attempted by in the same supply line, so the maintainer is also quite wasted time and energy when finding out the electromagnetic valve of et out of order exactly.
Summary of the invention
For the deficiency that the electromagnetic valve that overcomes existing controlled top exists, we have developed the controlled top of railway solenoid valve failure and have isolated warning device automatically.The utility model can solve an above-mentioned difficult problem well.It not only can be isolated the electromagnetic valve of et out of order rapidly and effectively with the power supply of its power supply, thereby has guaranteed the normal operation on other controlled top of same power supply power supply, and can point out in time, obviously and exactly which the electromagnetic valve of et out of order is.
The technical scheme that its technical matters that solves the utility model adopts is: it is by indicator lamp that the controlled top of railway solenoid valve failure is isolated warning device automatically, baffle plate, the aviation socket, isolating transformer, transistor diode, lead, aviation plug, base plate, transistor, housing, compositions such as wiring board, it is to erect to put wiring board in housing, the left side of wiring board has the middle part that isolating transformer is arranged, wiring board left side lower semiconductor diode, wiring board has transistor in the middle of the bottom, there is the aviation socket of a usefulness base plate by bolt on the left side that has housing to lean out, left upper end has indicator lamp, housing bottom fixes with base plate, draw lead, aviation plug in the connection.
At controlled top electromagnetic valve and the warning device of a special use of adjunction between to the power supply of its power supply.Under normal circumstances by an electronic switch in this circuit, electromagnetic valve coil and power supply are connected, and when electromagnetic valve coil such as is short-circuited, transships or open circuit at failure condition, can interrupt power supply rapidly and effectively it is powered, it make fault-indicating lamp be subjected to electroluminescence also can provide normal working power to support by electronic switch other in this device in time, so that can launch the FM radio set ripple that comprises some customizing messages to coding in this device and modulating emission circuit.What trigger above-mentioned these electronic switchs then is that employing is the formed sampling voltage of sampling circuit of core by the electric current of magnet coil with resistance.This voltage and then be input to one and differentiate and control circuit.In case electromagnetic valve coil is in faulty condition, differentiate and trigger voltage that control circuit can be exported enough sizes is immediately removed to trigger aforesaid electronic switch and finished corresponding action and function.
The beneficial effects of the utility model are, fault electromagnetic valve and power supply source in time and are effectively isolated, other electromagnetic valve work that can guarantee same power supply power supply is unaffected, thereby guarantee to be arrived smoothly the place of expection, make railway transport vehicle marshalling work be able to safety, efficiently, carry out in an orderly manner by the vehicle of rolling.When the utility model involves with signal lamp and FM radio set, indicate exactly and transmission comprises fault electromagnetic valve position, relevant information such as kind and numbering, convenient for maintaining people finder fault electromagnetic valve and keeping in repair greatly, improved work efficiency greatly, alleviated labour intensity, reduce maintenance cost, and be convenient to improve the level of management of maintenance work.
