Abstract
The utility model relates to belt and transmits field, specifically a kind of fender guard preventing belt tearing.A figure of eight wire coil is filled in belt moving direction every 60 meter amperes in belt internal vertical, described figure of eight wire coil is not communicated with up and down at infall, two positions of two circle hearts of corresponding figure of eight wire coil described in any one directly over belt, one another installation induction coil of permanent magnet is installed, the two ends of induction coil are connected on photoelectrical coupler, photoelectrical coupler connects PLC programmable logic controller (PLC), PLC programmable logic controller (PLC) connects warning device.The beneficial effects of the utility model are: the utility model detects belt operation conditions by the PLC programmable logic controller (PLC) moment, once find to transmit extremely, control belt in time and stop, and send warning.
Description
Technical field
The utility model relates to belt and transmits field, specifically a kind of fender guard preventing belt tearing.
Background technology
Belt conveyor line also claims band conveyor, the article that belt feeder uses the continuous of load-transfer device or intermittent moment to carry various weight different, both can carry various bulk cargo, and also can carry the part goods that the piece weight such as various carton, packaging bag are little, of many uses.The material of conveying belt of belt machine has: the various material such as rubber, silica gel, PVC, PU, except the conveying for common material, also can meet the conveying that oil resistant, withstanding corrosion, electrostatic prevention etc. have particular/special requirement material.Adopt special food stage load-transfer device, the requirement of the industries such as food, pharmacy, daily-use chemical industry can be met.Belt feeder equipment characteristic: steadily, material and load-transfer device do not have relative motion, can avoid the damage to transported substance in belt feeder conveying.Noise is less, is suitable for the more quiet occasion of operating environment requirements.Structure is simple, is convenient to safeguard.Energy consumption is less, and use cost is low.But for a long time always perplex by belt tearing fault, be worth the load-transfer device of unit even up to a million of hundreds thousand of unit, once tear accident, all will damage within a few minutes, cause huge economic loss.
Summary of the invention
Technical problem to be solved in the utility model is: how Timeliness coverage belt is torn, and repairs early.
The technical scheme that the utility model adopts is: a kind of fender guard preventing belt tearing, a figure of eight wire coil is filled in belt moving direction every 60 meter amperes in belt internal vertical, described figure of eight wire coil is not communicated with up and down at infall, two positions of two circle hearts of corresponding figure of eight wire coil described in any one directly over belt, one another installation induction coil of permanent magnet is installed, the two ends of induction coil are connected on photoelectrical coupler, photoelectrical coupler connects PLC programmable logic controller (PLC), PLC programmable logic controller (PLC) connects warning device.
The beneficial effects of the utility model are: the utility model detects belt operation conditions by the PLC programmable logic controller (PLC) moment, once find to transmit extremely, control belt in time and stop, and send warning.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein, 1, belt, 2, figure of eight wire coil, 3, permanent magnet, 4, induction coil.
Detailed description of the invention
As shown in Figure 1, a kind of fender guard preventing belt tearing of the utility model, a figure of eight wire coil is buried underground every 60 meters perpendicular to belt moving direction, described figure of eight wire coil is not communicated with up and down at infall, two positions of two circle hearts of corresponding figure of eight wire coil described in any one directly over belt, one another installation induction coil of permanent magnet is installed, belt is in operational process, figure of eight wire coil is through permanent magnet, figure of eight wire coil inside produces inducing current, inducing current produces induced field in one end of corresponding induction coil, induced field makes induction coil inside produce inducing current, the two ends of induction coil are connected on photoelectrical coupler, photoelectrical coupler connects PLC programmable logic controller (PLC), PLC programmable logic controller (PLC) connects warning device.Inducing current photoelectrical coupler gathering induction coil is sent to PLC programmable logic controller (PLC), inducing current is analyzed, when current signal becomes periodically, trigger alarm device and belt do not transmit switch, belt normally runs, current signal become not periodically time, trigger alarm device and belt transmit switch, belt is stopped, and sends warning.
