According to " metal and nonmetal mine safety rules (GB16423-2006) "; During the gig operation, the gap of brake shoe and brake disc remains on about 1mm, and should be not more than 2mm; Fine motion in the distance between 0.6～1.5 just, the amplitude of dish lock beat should be greater than 0.8～1.0mm; When gig did not move, brake shoe and brake disc locking gap were 0.0mm.
Traditional dish-type lock detecting device adopts micro-switch or travel switch; Its principle is exactly to gather the switching value signal of a dish-type lock action overshoot scope; Because it is 1～2mm that the device self-characteristic causes moving the dead band of switching; Just its precision is 1mm, and such precision uses the protection of middle and later periods to be actually invalid for brake shoe, can not effectively differentiate the wear pattern of brake shoe and the situation of spring performance; Cause the maintenance in later stage to increase greatly, and there is hidden danger in safety to the gig single-piece.
The utility model content
The utility model technical matters to be solved provides a kind of mine hoist dish lock detecting device, can effectively detect brake disc and the gap of brake shoe and the beat amplitude of brake disc of gig braking device.
The technical scheme that the utility model solves the problems of the technologies described above is following:
A kind of mine hoist dish lock detecting device; Comprise detection case, first displacement pickup and second displacement pickup; Said first displacement pickup is installed in the both sides of the brake shoe of gig braking device respectively; Said second displacement pickup is installed in a side of the brake disc of gig braking device, and said detection case is connected with first displacement pickup, second displacement pickup respectively.
Said detection case comprises main control unit and the signal processing module, display module, the annunciator that are connected with this main control unit respectively; Said first, second displacement pickup is transferred to signal processing module with the displacement signal that senses; Signal processing module converts this signal to displacement numerical value, and shows through display module.
Further, the relative displacement of said first displacement pickup sensing brake shoe and brake disc, the displacement signal that senses converts the displacement numerical value of brake shoe with respect to brake disc to through signal processing module; When main control unit detected said displacement numerical value and equals or exceeds the greatest measure situation that brake shoe and brake disc gap allowed, then main control unit control annunciator sent alerting signal.
Further, the beat amplitude of the said second displacement pickup sensing brake disc, the displacement signal that senses converts the beat amplitude of brake disc to through signal processing module; When main control unit detected said beat amplitude and equals or exceeds the maximum amplitude situation that the brake disc beat allowed, then main control unit control annunciator sent alerting signal.
Further, the resolution of said first displacement pickup and second displacement pickup is 0.01mm.
Further, said first displacement pickup is fixed on first bracing frame, and this first bracing frame is installed in the both sides of brake shoe, and second displacement pickup is fixed on second bracing frame, and this second bracing frame is fixed on the drg.
The utility model can detect brake disc and the gap of brake shoe and the beat amplitude of brake disc of gig braking device effectively; When the gap of brake disc and brake shoe equals or exceeds the greatest measure that is allowed; And when the beat amplitude of brake disc equaled or exceeded the maximum amplitude that is allowed, annunciator all sent alerting signal.This structure helps operating personal and detects drg so that it satisfies the deceleration and stopping performance requirement; Can observe the variation of beat amplitude of gap numerical value and the brake disc of brake disc and brake shoe through detection case intuitively; Help assisting operating personal to judge the eccentricities of the frayed and brake disc of brake shoe, trouble-shooting factor in time like this.
