Description
Technical field
The utility model is related to belt conveyor field, especially a kind of belt conveyor protection circuit.
Background technology
Belt conveyor, in order to prevent some from unexpectedly occurring, one is all set in machine internal when carrying out conveying material
A little protection devices carry out maintenance safe transport.The protection device of belt conveyor has stall, stifled slip, sideslip, stop in emergency, draw
Rope protection etc..The problem of occurring corresponding when belt conveyor is run is that protection device can be acted, and scheduling host computer can show report
Alert and centralized control system, which is automatically controlled, allows belt parking to ensure system safe and stable operation.
But protection device is again in itself that can also break down, and causes belt conveyor protection misoperation, and in the short time not
It is easy-maintaining, influence system operation.
Belt feeder protection device, which goes wrong, two kinds of situations, and one is failure of scene protection device itself, such as belt feeder
The proximity switch failure that stifled chute protection is used, causes belt feeder mistakenly stop car.If scene change proximity switch, influence time compared with
It is long.Two be that various protection circuits have earth fault, causes control loop to jump electricity, influence production.
Increase equipment protection throwing for the first situation, in in-system programming and move back button, this kind protection can temporarily be exited,
Emergent production, in the Awaiting Overhaul period, to ensureing that device is overhauled.Such as belt feeder block up that chute protection uses close to opening
Put water into, cause misoperation, when site inspection confirms to have no problem, scheduling directly can move back the stifled chute protection of the belt feeder
Go out, recover to drive, during the Awaiting Overhaul time, then change the proximity switch at scene.The systematic influence time can be so significantly reduced.
For second of situation, according to conventional processing mode, all it is to open live button box, is found and connect using universal meter
Ground circuit, the circuit is thrown away, allows system to resume production.Treat that second day repair time section is to look through earth fault again,
Handled.Often the time is longer for such a mode, and lookup trouble point use time is more, and the influence production time is longer.
Utility model content
The purpose of this utility model is to solve when detection switch breaks down to recover in the prior art at once
The problem of production, there is provided a kind of belt conveyor protection circuit.
To achieve these goals, the technical solution of the utility model is as follows：
A kind of belt conveyor protection circuit, including belt conveyor emergency flight control cabinet, the first pull switch, the second drawstring

Switch, first port, second port, the second pull switch formation loop；It is parallel between 3rd port and the 4th port
Drawstring emergency button.
Further, the belt conveyor emergency flight control cabinet includes fifth port and the 6th port, the fifth port
Or the 6th port be power port, another port be offset signals test side, outside belt conveyor emergency flight control cabinet, the 5th
Deviation switch is provided between port and the 6th port.
Further, the belt conveyor emergency flight control cabinet includes the 7th port and the 8th port, the 7th port or the
Eight ports are power port, and another port is blocking chute signal detection end, outside belt conveyor emergency flight control cabinet, the 7th
Stifled pass of shying away is provided between port and the 8th port.
Further, the belt conveyor emergency flight control cabinet includes the 9th port and the tenth port, the 9th port or the
Ten ports are power port, and another port is stall signal test side, outside belt conveyor emergency flight control cabinet, the 9th port
And the tenth be provided with stall switch between port.
Further, the 7th port and the tenth port are same port, and are power end.
Further, the magnitude of voltage of the power end is 220V.
The utility model has the advantage of：When being that detection switch short circuit phenomenon occurs and causes belt conveyer not work,
The technical scheme finds failure quickly by way of closing each way switch, and by controlling the states of various switches just can be with
Start belt conveyer work, corresponding circuit, such pole are switched and repair accordingly until being replaced during belt conveyer shutdown
Big shortens the accident impact time.
Brief description of the drawings
Fig. 1 is the external electrical of the belt conveyor emergency flight control cabinet in a kind of belt conveyor protection circuit of the utility model
Lu Tu.
Embodiment
As shown in figure 1, a kind of belt conveyor protection circuit, including belt conveyor emergency flight control cabinet, the first drawstring are opened
Pass, the second pull switch, the belt conveyor emergency flight control cabinet include first port, second port, the 3rd port, the 4th end
Mouth and high-voltage wire cabinet, the 3rd port and the 4th port are two output ends of high voltage power distributing cabinet, the input of high voltage power distributing cabinet
Hold as power end, the magnitude of voltage of power end is 220V.
Inside belt conveyor emergency flight control cabinet, the inspection of drawstring signal is provided between the first port and second port
Survey end, outside belt conveyor emergency flight control cabinet, the 4th port, the first pull switch S1, first port, the second end
Mouth, the second pull switch S2 are connected in series；Drawstring emergency button S3 is parallel between 3rd port and the 4th port.Just
