(left side skew), before skip bucket is run up entrance cage guide, straight rail by Zhuan Kuang position, shaft bottom, is fixed on skip bucket body insulation board
Sensing touch panel contact with the steel wire brush being fixed on well head steel guide stock, magnetic induction switch detection signal formed back
Road also exports.
If set square is not in horizontal normal position, magnetic induction switch and the most a certain piece of Magnet vis-a-vis, magnetic strength
Contact action in inductive switch, when skip bucket operation is extremely with the steel wire brush of sensing touch panel good contact, relay coil obtains electric
Normally opened contact adhesive, digital quantity input module passage obtains switching value 1, and input module transmits a signal in the program of PLC,
PLC passes through digital output module channels output switch amount 1 after handling it signal, makes set square deflection alarm lamp
Bright, PLC then order elevator ramp to stop.
If set square is in horizontal normal position, magnetic induction switch and Magnet can not vis-a-vis, magnetic induction switch touches
Point is failure to actuate, when skip bucket runs to during with sensing touch panel good contact steel wire brush, and relay coil must not be electric, and normally opened contact is not
Adhesive, digital quantity input module passage obtains switching value 0, and input module transmits a signal in the program of PLC, and PLC is to signal
By digital output module channels output switch amount 0 after handling it, set square deflection alarm lamp does not works, and elevator is just
Often run.
The present invention is simple, material easily obtains, and achieves the best effect, can detect that multi-rope friction type carries
Rise the location status of machine first-rope hinger triangle connecting plate, improve mine hoist safety coefficient, run for high intensity and play
Positive effect.
