Detection switch, putty detection switch etc., these switches are electrically connected with by relay and Central Control Room, in normal operating conditions,
Above-mentioned each switch is in normally off, and when belt feeder breaks down, then the switch for detecting corresponding failure is disconnected, relay
Device coil blackout, Central Control Room receives signal, and sends alarm or cut-out belt feeder working power according to signal.
But in actual production process, because the control cable and power cable of belt feeder mix, control electricity
There is 220V power supply signal in cable, because the reason such as electromagnetic coupled, insulation ag(e)ing, humid environment is made under hundreds of meters of distance
Induced-current is produced into control circuit, causes relay after connected in series switch off, coil both ends still exist higher
Voltage difference, as relay be failure to actuate, can not normally to Central Control Room send fault-signal, cause Central Control Room not connect smoothly
The signal of belt feeder failure is received, the safe operation of belt feeder can not be ensured.
Utility model content
Technical problem to be solved in the utility model is：There is provided a kind of belt feeder security system, it can be ensured that belt feeder event
During barrier, relay sends fault-signal to Central Control Room in time.
In order to solve the above technical problems, the technical solution adopted in the utility model is：Belt feeder security system, including middle control
Detection switch behind room and the tight guard's valve of deviation switch, drawstring being distributed on belt feeder working line, skidding detection switch, tear
With putty detection switch, detection switch, putty detection after the tight guard's valve of above-mentioned deviation switch, drawstring, skidding detection switch, tear
Switch is electrically connected with by relay and Central Control Room respectively, the tight guard's valve of the deviation switch, drawstring, skidding detection switch, is torn
Split rear detection switch, putty detection switch is ganged switch, and respectively at corresponding relay connect, the other end of relay
Connect zero-power line, a contact portion power firestreak of ganged switch, another contact ground.
As a kind of preferable scheme, the both ends of any relay are parallel with an electric capacity.
As a kind of preferable scheme, the Central Control Room includes controller and PLC, and the deviation switch, drawstring are tightly stopped
Detection switch, putty detection switch are connected to PLC by relay respectively after pass, skidding detection switch, tear.
As a kind of preferable scheme, the PLC is the types of A-B RSLogix 5000.
The beneficial effects of the utility model are：When being disconnected by by a contact ground of ganged switch, making ganged switch,
The both ends of relay coil are grounded, and form equipotential so that and relay coil does not produce induced electricity in the power-off state, so as to
When ensuring belt feeder failure, relay sends fault-signal to Central Control Room in time so that Central Control Room can be in time to belt feeder event
Barrier makes shutdown control.

Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail.
Belt feeder security system as shown in Figure 1, including Central Control Room 1 are opened with the sideslip being distributed on belt feeder working line
Detection switch 5 and putty detection switch 6 after pass 2, the tight guard's valve 3 of drawstring, skidding detection switch 4, tear, above-mentioned deviation switch 2,
Detection switch 5 and putty detection switch 6 are respectively by relay 7 with after the tight guard's valve 3 of drawstring, skidding detection switch 4, tear
Control room 1 is electrically connected with, and Fig. 2 is the connection circuit diagram of deviation switch, and the circuit diagram of remaining various switch is similar, the sideslip
Detection switch 5 and putty detection switch 6 are ganged switch after switch 2, the tight guard's valve 3 of drawstring, skidding detection switch 4, tear,
And connected respectively with corresponding relay 7, the other end connection zero-power line of relay 7, a contact portion of ganged switch
Power firestreak, another contact ground.
When being disconnected by by a contact ground of ganged switch, making ganged switch, the both ends of the coil of relay 7 connect
Ground, formed equipotential so that the coil of relay 7 does not produce induced electricity in the power-off state, so that it is guaranteed that during belt feeder failure after
Electrical equipment 7 acts, and sends fault-signal to Central Control Room 1 in time so that Central Control Room 1 can make shutdown control to belt feeder failure in time
System.
