Background
The brake is one of main parts for ensuring the safe and normal operation of the crane, and directly influences the accuracy and reliability of the movement of each mechanism, even the personal and equipment safety. Because the crane works in an intermittent and repeated mode, the starting and braking actions are frequent, the brake shoe is seriously abraded, the brake torque is reduced due to untimely replacement, and accidents are possibly caused.
Simultaneously, in the adjustment process, improper clearance between the brake shoe and the brake wheel when the brake shoe is opened can cause:
(1) When the wheels of the cart are respectively driven, the two ends of the cart running mechanism are not synchronous when the cart running mechanism is started and braked due to uneven braking of the two ends, the cart body swings, the rail gnawing quadrant is caused, the abrasion of the rail and the wheel rim is aggravated, and the service life is shortened;
(2) The braking clearance is too small, so that the starting and braking time is short, and the swinging amplitude of the suspended object is large due to the inertia effect;
(3) The brake clearance is too large, so that the brake time is prolonged, and even the brake failure occurs.
Therefore, monitoring the air gap state of the brake in real time is one of the key factors for guaranteeing the safe operation of the crane.
