Abstract

The utility model relates to a wind exhaust device for the angle cock of the air pipe of a train. The lower parts of locomotives and cars are respectively provided with transmitters and receivers. A pressure sensor which is arranged on the blast main of the train transports fault pressure signals to the transmitters of the cars after detecting the fault pressure signals. The receivers of the locomotives immediately push the braking button after receiving the fault pressure signals, and braking signals pass through the transmitters of the locomotives to the receivers of the cars and drive an actuating mechanism to work. In this way, the urgent wind exhaust of the train is achieved, and the aim of safe brake is achieved. The utility model has the advantages of high automatization, high safety, high sensitivity, strong applicability, etc.

Description

Warning and wind device for air hose angle cock closing of train

The utility model relates to a kind of air exhausting device of railway train blast pipe angle cock, particularly a kind of train operating safety device.

Railroad train is in the middle of operation, the train line angle cock is closed phenomenon and happens occasionally, cause train air draft to brake, collide, emit signal, damage the road fork, serious accident takes place, also do not have a kind of automatic monitoring, warning now and control the device that the train line angle cock is closed.

The utility model purpose provides and a kind ofly at train line angle cock place sensor is installed, to locomotive receiver auto alarm, and close the warning air exhausting device to the train line angle cock of locomotive emitter and compartment receiver and control executing mechanism by the compartment emitter by the emergency brake button.

The utility model is by the emission that is installed in locomotive and the compartment, receiver, pressure sensor, actuating unit is formed, locomotive and compartment emission, receiver is separately positioned in the locomotive and bottom, compartment and be provided with numeral and light display apparatus, the pressure sensor or the locomotive emergency brake button that are installed on the train blast main pass through repeating resistance, coupling capacitance links to each other with emitter radioamplifier collecting electrode transmitter coil, the mouth of the high frequency generator of being made up of quartz crystal and transistor inserts resonant tank and is coupled to the base stage of radioamplifier, the transmitter coil of radioamplifier inserts emitting antenna, receiver antenna passes through by L, the resonant tank that C forms inserts frequency converter, quartz crystal inserts frequency converter, the output of frequency converter inserts detecting circuit behind intermediate frequency coil, detecting circuit output inserts driving amplifier after Coupling Potential device and coupling capacitance, driving amplifier output inserts loud speaker and display circuit, the magnet-switch of the output of driving amplifier or access actuating unit, the contact of magnet-switch inserts the magnetic coil of electropneumatic valve and time-delay reservoir by lead, the middle part of magnetic coil is provided with moving armature, the moving armature bottom is equipped with valve and following valve, air compartment communicates with time-delay reservoir air compartment by the air channel, time-delay reservoir air compartment top is provided with vent valve, sandwich valve and retracing spring, time-delay reservoir air compartment communicates with train line.

The utlity model has after the train line angle cock is closed can auto alarm, air draft brake automatically, highly sensitive, dependable performance, characteristics such as compatible with environment is strong, degree of automation is high, safe and applicable.

Accompanying drawing 1 is transreceiver and a read out instrument scheme of installation in the utility model locomotive.

Accompanying drawing 2 is the utility model transmitter circuitry schematic diagram.

Accompanying drawing 3 is the utility model receiver circuit schematic diagram.

Accompanying drawing 4 is the electropneumatic valve and the time-delay reservoir section of structure of the utility model actuating unit.

Below in conjunction with accompanying drawing the utility model is further described, structure of the present utility model and principle of work are to realize like this, after the train line angle cock is closed, because pent compartment reservoir can not in time fill wind, wind was let out in the compartment naturally when the not enough 6kg(of wind pressure was flat, replenish by the locomotive air-supply, respectively save the compartment so at ordinary times and must guarantee that wind pressure is 6kg or 5kg), CYG-02 type pressure sensor is installed on train line, after angle cock is closed, blast descends, owing to can not in time fill wind, when wind pressure is reduced to 5.7kg, pressure sensor sends signal automatically, this signal is sent to the emitter on the compartment, this emitter is transmitted to the locomotive receiver with this signal, locomotive is reported to the police partly reports to the police, and demonstrate pent compartment joint number simultaneously, so that allowing the driver in time understand is closed at certain compartment angle cock, and in time handle, principle of work is such, pressure sensor is by repeating resistance 2, coupling capacitance 3 links to each other with emitter radioamplifier 4 collecting electrode transmitter coils 5, realize collector modulation, form high frequency generator by quartz crystal 6 and transistor 7, oscillation frequency is 29MHZ, and oscillator signal also is coupled to the base stage of radioamplifier through resonant tank 8, the transmitter coil of radioamplifier inserts emitting antenna 9, and the modulation signal after modulation is launched through antenna.

Be installed in the receiver of locomotive chamber, after receiving this frequency signal, pass through L, the resonant tank 10 that C forms inserts frequency converter 11, the one-level frequency conversion is arranged in the integrated package SL315, the two-stage intermediate frequency, quartz crystal 12 inserts frequency converter, by the intermediate-freuqncy signal of quartz crystal and frequency converter output through two-stage intermediate frequency coil 13, detecting circuit 15 is inserted in 14 backs, sound signal after the detection inserts driving amplifier 18 after potential device 16 and coupling capacitance 17, driving amplifier output inserts loud speaker 19 and display circuit, read out instrument 1 demonstration work, after the driver receives alerting signal, take the emergency brake measure immediately, after the driver presses the emergency brake button, brake signal is delivered to the amplifying circuit of locomotive emitter, its transmission circuit structure and principle of work are identical with the compartment emitter, but by the oscillator oscillation frequency that the transistor AND gate quartz crystal is formed is 35MHZ, after receiving this frequency signal, the compartment receiver carries out frequency conversion, detection, after the amplification, the work of driving actuating unit, the compartment receiver circuit structure here is identical with the locomotive receiver with principle of work, the structure of actuating unit and working process are such, after the compartment receiver receives brake signal and amplifies, the magnet-switch of actuating unit gets electric adhesive, at this moment the magnetic coil 20 of electropneumatic valve and time-delay reservoir conducts electricity, and with moving armature 21 adhesives, be arranged on the last valve 22 of air compartment 24 and move, following valve 23 is opened, wind in the blast main enters A chamber in the time-delay reservoir air compartment 26 by air channel 25 by the D chamber, A chamber air pressure is at lamina membranacea and the pressure that colludes on the tool to be produced, after the bounce that has overcome back pressure on the sandwich valve 28 and vent valve 27 retracing springs 29, so coming heart valve to open the D chamber immediately is communicated with the B chamber, blast main communicates with train line 30, train pipe emergency exhaust, the train emergency braking, reach the brake purpose, guarantee that the train brake security of system is reliable.
