Technical field
The utility model relates to a kind of break device for monitoring running, and specifically a kind of crane braking system detects and self-diagnosable system.
Background technique
Existing crane gear such as the majorities such as the overhead traveling crane of factory, tower crane for building are the hub type brakes installed, and this break is four-bar linkage structure, is made up of mechanisms such as front and back brake arm, brake shoe, brake spring, spring pull bar, base and brake opening devices.
Hundreds thousand of, China is being all in the spreadable life with hoist, break (also known as " brake opening device ") on hoist is in the process using break, the thickness of brake shoe lining will soon wear and tear thinning usually, and brake shoe lining with adopt between brake shoe more rivet, pressing plate is installed or the mode such as bonding is fixed.In the using process of break, the displacement, disengaging etc. of the wearing and tearing thinning or brake shoe lining of brake shoe lining, all can cause security incident to occur.
Along with using the thinning of brake shoe lining, the gap between the bolt that declutches (or spring pull bar) of break output shaft and ejection brake arm will diminish gradually, will dieback brake arm when gap is zero, makes misfunctioning of brake.In addition, when the output shaft of break and dynamic iron core because of wearing and tearing surface become coarse after, just likely there is moving mandrel's jam phenomenon, also can cause the gap smaller that break output shaft and brake arm declutch between bolt (or spring pull bar), and even make misfunctioning of brake.
Gap smaller between the bolt that declutches (or spring pull bar) of break output shaft and brake arm, even dieback, after break power-off, the pressure of brake spring will be made not to be delivered on break, also just can not be delivered to brake shoe to be lining with, braking action be lost, misfunctioning of brake.
Along with the wearing and tearing of brake shoe lining are thinning, each wearing and tearing connecting hinge and hole, the brake spring being in impaction state also all can be made to discharge elongated gradually, or As time goes on, the pressure of brake spring diminish, and braking moment is diminished, to misfunctioning of brake.
In break using process, if there is superheating phenomenon, make brake coil (or motor) scaling loss, winding deformation occurs, or motor distortion, make the phenomenons such as break output shaft generation jam.
Due to the accident that above many reasons cause, again and again there is the hoisting hook thing of hoist or the falling accident of box in the last few years, cause the injures and deaths of personnel and the loss of property.Therefore, technology upgrading is taked to the break that hoist uses, minimizing accident occurs, and is the task of top priority of lifting industry department and brake producing enterprise.
