Description of drawings

Fig. 1 is the local structure scheme drawing according to the jigging conveyer of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of the specific embodiment.

This jigging conveyer comprises: electrical motor, exciting parts, vibration hopper and PLC controller; As shown in Figure 1; Vibration hopper 1 passes through spring 2 resilient mountings on jigging conveyer support 3; The electrical motor (not shown) drives exciting parts (not shown) and does periodically crank motion, and then drives vibration hopper 1 and do periodically crank motion, and PLC controller (not shown) is connected with electrical motor; This jigging conveyer operation detecting device comprises: be arranged in the amplification zone of vibration hopper 1 vibration downwards near switch 4, insert the PLC controller near the signal output part of switch 4.

This jigging conveyer operation detecting method be conveyer vibration hopper 1 downwards the amplification zone of vibration be provided with one with PLC controller bonded assembly near switch 4, come jigging conveyer is moved detection.Near switch is kind of a switching mode sensor (being noncontacting switch); Do not need to carry out mechanical contact and manipulable position switch with movable parts; When conveyer vibration hopper 1 near the sensitive surface of switch during to operating distance; Do not need mechanical contact and apply any pressure to make switch motion, thereby control command is provided to automation control system.Conveyer vibration hopper 1 downwards the amplification zone of vibration be lower edge with vibration hopper 1 when static residing plane be critical surface; When conveyer vibration hopper 1 vibration downwards promptly gets into should the zone; Promptly produce approach signal near switch 4 this moment, and then is transferred to the PLC controller, when conveyer vibration hopper 1 upwards vibration break away from should the zone time; Above-mentioned approach signal interrupts; Like this along with vibration hopper 1 periodically the approach signal of the crank motion certain time of generation being interrupted near switch be transferred to the PLC controller, jigging conveyer moves just often, the approach signal that the PLC controller receives continued for 5 seconds.

Concrete testing process comprises:

Steps A: in the vibration hopper 1 downward amplification zone of vibrating of jigging conveyer, be provided with, in vibration hopper 1 vibration entering downwards amplification zone, near switch 4 generation approach signals near switch 4; Leave in the amplification zone when vibration hopper 1 upwards vibrates, approach signal interrupts;

Step B: produce the approach signal that is interrupted to the PLC of jigging conveyer controller transmission vibration hopper 1 periodicity crank motion near switch 4;

Step C: when PLC controller identification approach signal continued for 5 seconds, judge that then the jigging conveyer operation is normal;

Step D: when PLC controller identification approach signal is not when continuing for 5 seconds, then judge jigging conveyer operation mal, and then close the electrical motor of jigging conveyer, stop jigging conveyer work, trouble-shooting.

After jigging conveyer quits work; When finding jigging conveyer operation normal (this detection can be passed through the service condition of direct viewing vibration hopper) through further the detection; PLC controller identification be not every at a distance from 5 seconds receive be interrupted approach signal be since detection near switch 4 or circuit problem is arranged the time; For fear of unnecessary long-time shutdown, then can connect bypass through the PLC controller, conveyer temporarily is not with is detected operation.

Through near switch to PLC controller transmission vibration hopper periodically crank motion produce be interrupted approach signal; Can detect the shakeout machine malfunction that causes owing to the shakeout machine motor belt is disconnected, bearing is bad, exciting agency problem etc.; Avoid jigging conveyer and melt pit equivalance sand, and the preventive device fault is not magnified.Be specially adapted to the vibration conveying equipment of industrial and mining enterprises, particularly unattended equipment, this method of inspection can also be applied in the periodically reciprocating Equipment Inspection, improve the effective monitoring degree of equipment, reduce breakdown of equipment and enhance productivity.

More than a disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
