In defeated, because tractive force is larger, and heavy duty easily produces inside and happened occasionally by fluctuation, disconnected hook accident, now not
First section or device are judged.Therefore circuit personnel or driver's naked eyes can only be leaned on to judge whether disconnected hook, sometimes in car
Find that the hitch at middle part has broken after running some time, the meeting inertia motion of broken compartment is abnormally dangerous.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and the locomotive proposed breaks hook protection dress
Put.
To achieve these goals, the utility model employs following technical scheme：
Locomotive breaks hook protection device, including circuit board, and diode, the first relay and second are welded with the circuit board
Relay, interlocking has second switch on second relay, and two output ends of second switch are connected to sound report
Alert device and light-emitting alarm, the voice guard and light-emitting alarm are respectively welded on circuit boards, second relay
Output end is connected with the output end of the first relay and the negative pole of 110 volts of power supplys, and the input of second relay is connected with
The positive pole of diode, and the negative pole of diode is connected with first pressure switch and second pressure switch, the first pressure switch
The other end be connected with the positive poles of 110 volts of power supplys, the other end of the second pressure switch and the input phase of the first relay
Connection, first relay interconnection have first switch, and one end of the first switch is connected with the input of the second relay
Connect, and the positive pole of the other end of first switch and 110 volts of power supplys is electrically connected with.
Preferably, the first pressure switch and second pressure switch are separately mounted in the braking gas circuit of locomotive, and the
The model 12NN-K4-N4-B1A-TTX834 of one pressure switch and second pressure switch.
Preferably, first relay and the second relay are electric current relay.
Preferably, the first pressure switch is the pressure switch of detection brake-cylinder pressure, and the second pressure, which switchs, is
The pressure switch of detection braking distributing valve pressure.
Locomotive described in the utility model breaks hook protection device, works as locomotive work, and brake it is ready after, checking cylinder has
Pressure, first pressure switch closure, after the brake pipe that locomotive is used for carriage brake has pressure, second switch disconnects, and now the
One relay is not worked, and then the second switch interlocked with the second relay is not turned on so that voice guard and light report
Alert device is not alarmed；After hitch disconnects, the brake pipe that locomotive is used for carriage brake also disconnects therewith, and now second pressure switchs
Simultaneously as pressure is relatively low and closes so that first actuating of relay, the chain closure of first switch, and now exclusive circuit, second
Relay closes, and then is turned on the second switch that the second relay is interlocked so that voice guard and visual alarm enter
Row alarm so that driver can have found to break in time the compartment fallen, and be handled in the very first time, avoid the hair of security incident
Raw, the utility model reminds driver when hitch is broken by voice guard and visual alarm so that driver can be right
The break compartment that falls carries out very first time processing, avoids the generation of security incident.
Brief description of the drawings
Fig. 1 be the utility model proposes locomotive break the structural representation of hook protection device.
In figure：1 first switch, 2 first pressures switch, 3 second pressures switch, 4 diodes, 5 first relays, 6 second
Relay, 7 second switches, 8 voice guards, 9 light-emitting alarms.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.
Reference picture 1, locomotive break hook protection device, including circuit board, and diode 4, the first relay 5 are welded with circuit board
With the second relay 6, interlocking has second switch 7 on the second relay 6, and two output ends of second switch 7 are connected to
Voice guard 8 and light-emitting alarm 9, voice guard 8 and light-emitting alarm 9 are respectively welded on circuit boards, the second relay
The output end of device 6 is connected with the output end of the first relay 5 and the negative pole of 110 volts of power supplys, and the input of the second relay 6 is connected with
The positive pole of diode 4, and the negative pole of diode 4 is connected with first pressure switch 2 and second pressure switch 3, first pressure switch 2
The other end be connected with the positive poles of 110 volts of power supplys, the other end of second pressure switch 3 and the input of the first relay 5 are connected
Connecing, the interlocking of the first relay 5 has first switch 1, and one end of first switch 1 is connected with the input of the second relay 6, and the
