How to prevent the phenomenon of crane rail gnawing
Hoist equipment has become an indispensable in many areas of the lifting device, and therefore, its safety is very important. But once the chain block rail gnawing on great harm, would constitute a serious crane incidents. Constitute the reason is gnawing rail messy, carts track overlap Degrees, tilt, gauge and other construction technology parameter error will cause the occurrence of eating track. But there is a big limitation of traditional identification
methods, it is difficult to achieve on the track to make a bite precautions.
1, in this case, anti-bite rail technology has been widely used. Gantry crane This technique can only be adjusted by means of electrical methods can not completely eliminate gnawing track, only in a small range of repeat adjustment, so the longer the effect of the use of the more obvious.
Anti-bite rail technology can be useful to reduce the carts wheels, coupling, reducer, motor and other equipment consumption costs, easing the goods transported across the billet hostile, and reduce the number of manual repair costs, reduced staff helpful labor intensity. Not only that, but also to prevent the car Deformation of the body, tracks, beams play a protective role, and to ensure the safety of the crane work.
2, can move through appropriate planning stiffness, especially horizontal stiffness to prevent gnawing rail. Such as the main beam is usually used to change the level of stiffness and rigidity of the box girder excellent planning; two level walkway of adjuvant effect, increasing the level of the bridge stiffness; would bias rail box girder diaphragms plus Strong, made of horizontal structure planning; main beam in the horizontal plane and the end beam rigidly connected to form rigid frame plans.
3, due to hoist equipment bound span ratio of the base away from the freedom and the allowable deflection is inversely proportional to the hoist equipment , the hoist equipment can guarantee a certain freedom torsion. Freedom beyond the allowable deflection when the crane, through the planning of the work two metal working resistance of re-allocation of the two-speed Degree tends together, arrived in synchronization.
