The variation of pressure judges.Present embodiment is preferably sentenced using by acquiring the position relationship of associated components in contracting brake mechanism 20
20 whether complete band-type brake of disconnected contracting brake mechanism, specifically, the driving mechanism 10 include hydraulic cylinder 11 and tie rod arm 12, the hydraulic pressure
Cylinder 11, the tie rod arm 12 and the contracting brake mechanism 20 are hinged successively, and the testing agency 30 is by detecting the tie rod arm
Detect the 20 whether complete band-type brake of contracting brake mechanism in 12 shift position.It is cut with scissors with tie rod arm 12 one end of the telescopic rod of hydraulic cylinder 11
It connecing, during telescopic rod moves up and down, the position of tie rod arm 12 also changes therewith, when 20 complete band-type brake of contracting brake mechanism,
The position of tie rod arm 12 is recorded, correspondingly, testing agency 30 can detect whether tie rod arm 12 reaches the position, to judge to embrace
The whether complete band-type brake of brake mechanism 20.
The likes such as proximity sensor may be used in testing agency 30, but in order to avoid proximity sensor or equipment are given birth to
Rust and caused by space change, caused by signal detection it is inaccurate, present embodiment preferably detects tie rod arm in the following ways
12 change in location, specifically：The testing agency 30 includes photoelectric sensor 31 and reflector 32, the reflector 32 and institute
It states one of photoelectric sensor 31 and is set to the tie rod arm 12, it is another in the reflector 32 and the photoelectric sensor 31
One is set to 12 side of the tie rod arm, and the photoelectric sensor 31 is moved to the contracting brake mechanism 20 in the tie rod arm 12
When capableing of the position of complete band-type brake, band-type brake signal is sent out to the control mechanism 40 by incuding the reflector 32.Photoelectric transfer
Sensor 31 and reflector 32 are not limited by product Self-variation, to extend the service life of testing agency 30, and improve inspection
Survey precision.
With the abrasion of associated components in contracting brake mechanism 20, the position of the tie rod arm 12 in complete band-type brake of contracting brake mechanism 20
It can change, in order to avoid the measurement error that the variation is brought, can be realized by adjusting the position of reflector 32, example
Such as, the reflector 32, which is arranged, to be moved relative to the tie rod arm 12, after the abrasion of associated components in contracting brake mechanism 20, suitably
The position for changing reflector 32, to keep measurement more accurate.Sliding rail, kidney-shaped may be used in the mode that reflector 32 is movably arranged
The modes such as slot realize that it will not be described here.
In order to improve the transmission efficiency of signal, the photoelectric sensor 31 passes through flame-retardant shielding control with the control mechanism 40
Cable electrical connection processed.Preferably, the detection range of the photoelectric sensor 31 is 20mm-400mm.
