Dense-medium separator is a kind of coal separation equipment that often uses in the coal industry, adopt magnetite powder and coal dust as medium solid, fluidisation under the effect of water or air in assorting room, is discharged with discharge mechanism respectively by light, the heavy product after the density stratification.Hypostasis scrapes by scraper conveyor, because the conveyor continuous operating time is long, load is heavy, the interior environment of machine is abominable, easily causes the problems such as conveying mechanism wearing and tearing, distortion, fracture.If can in time find the carrier chain fault, and in time stop, to greatest extent cut loss.Existing carrier chain pick-up unit mainly contains two classes: (1) induction installation is installed on the power wheel, judges by the velocity contrast that detects driven wheel to have or not the chain rupture fault.The method is only applicable to the single-row chain conveyor, strand chain rupture fault that can't Measurement accuracy double strand chain conveyor; (2) induction installation rides on the carrier chain by feeler lever, has or not contact with sensor and makes the corresponding failure judgement by detecting chain link.The method can not effectively detect jumps chain, the fault of grinding one's teeth, and also can't detect the function imperfection to carrier chain direction of motion, speed; Easily cause erroneous judgement to shut down during the carrier chain transverse shakiness, poor reliability, and in the difficult installation of two medium chain conveyors.In sum, present carrier chain supervising device ubiquity operation is unreliable, sensitivity is low, the incomplete problem of function.
Summary of the invention
The purpose of this utility model provides the coal separation machine carrier chain integrated monitoring apparatus of a kind of installation easy to operate, easy, dependable performance, solves that the operation of present carrier chain supervising device ubiquity is unreliable, sensitivity is low, the incomplete problem of function.
For achieving the above object, the technical solution of the utility model: the carrier chain integrated monitoring apparatus comprises upper monitoring computing machine, main control unit, external input circuit, reset circuit, warning circuit, engaged wheel, carrier chain, driving wheel, speed detection unit, fault detection unit, motor control unit and dragging motor.
Upper monitoring Computers and Communication cable, link adaptation device form communicating circuit, with the main control unit both-way communication; External input circuit, reset circuit, speed detection unit and fault detection unit are connected with the signal input part of main control unit and are connected; Speed detection unit is positioned at a side of driving wheel, and speed detection unit comprises induction iron plate and sensor, and the induction iron plate is fixed on the driving wheel side, and two sensors are with the poor installation of 1/4 or 3/4 periodic phase; Fault detection unit is positioned on the running orbit of carrier chain, and fault detection unit comprises sensor, spring and induction iron block, and the induction iron block hangs on the spring; The control output end of main control unit is connected with motor control unit with warning circuit respectively, and motor control unit is connected with dragging motor, forms halt circuit; Dragging motor drives driving wheel and rotates, and connects by carrier chain between engaged wheel and driving wheel; Warning circuit comprises sound, optical element forms warning circuit, and warning circuit can send the sound and light alarm signal.
Described main control unit 2 is a kind of among MCU, PLC and the DDC.
Beneficial effect: owing to adopted such scheme, by the working condition of upper monitoring computer monitoring main control unit, main control unit receives, processes the signal that detecting unit sends, and control halt circuit and warning circuit; Speed detection unit detects running speed and the direction of carrier chain, fault detection unit detect two carrier chains chain rupture, fall chain, jump the faults such as chain, scraper plate dislocation; Sound and light alarm and stop dragging motor are carried out in the order that warning circuit and halt circuit execution main control unit send; Can self-locking after main control unit is processed fault-signal, again play the time spent must reset by main control unit by reset circuit.Detect in real time the operational factor of carrier chain and in time find carrier chain fault, stop dragging motor, effectively avoid chain rupture, fall chain fault generation rear motor and continue operation the structures such as scraper plate, fluidizer are damaged, delimit the organizational structure for the operations staff of minimizing system simultaneously and reduce maintenance workload.Be connected with the signal input part of main control unit by external input circuit, reset circuit, speed detection unit and fault detection unit and be connected.Control output end by main control unit is connected with motor control unit with warning circuit respectively; motor control unit is connected with dragging motor; form halt circuit; can in time detect generation and the stop dragging motor of carrier chain fault; effectively avoid the chain fault to cause further destruction, provide condition for the minimizing operations staff of system delimits the organizational structure and reduces maintenance workload.It is simple in structure, and is sensitive reliable, is easy to install, and maintenance is convenient.
