Abstract

THE RUNNING PART OF A BRIDGE CRANE, containing running wheels fixed in the end beams and axle rollers with axle rollers with shock absorbing elements, the rollers are placed at least on one side of the road wheels, lt and h and so that, in order to increase its reliability and durability by reducing the dynamic loads on the rollers parallel to the rail at the location of the displacement of the ends of the joined rails, the axes of the rollers are connected to the end beams by means of two joints of freedom and damping elements .razmescheny on the axles and rollers are in the form of truncated cones tonkostennk slotted along the generatrices.

long N in the longitudinal axis (figure 3).

The displacement of the roller 2 and the axis 7 occurs by rotating the spherical hinge housing 12 12. Dynamic loads are reduced due to the damper 3, since the thin walls with slots 8 along the truncated cone 9 abutted into the yoke 18 and elastically deformed in the radial pressure direction (Fig .2 and 3). Stiffness: the damping element 3 is chosen such that under the action of static

loads close to the limit for materials of roller 2 and axle 7, roller 2 deviates to the level of the profile of the flange of the wheel, 1, while the flange of the wheel 1 takes on a part of these loads.

The use of the proposed construction of the undercarriage of a bridge crane reduces the dynamic loads and increases the reliability and durability of the horizontal unit, the roller and the undercarriage of the crane as a whole.

Claims (1)

RUNNING PART OF A BRIDGE CRANE, comprising driving wheels fixed in the end beams and nodes of rollers horizontally located on the axles of the rollers with shock absorbing elements, said rollers being placed on at least one side of the running wheels, characterized in that, in order to increase its reliability and durability by reducing the dynamic loads acting parallel to the rail on the rollers at the displacement of the ends of the joined rails, the axes of the rollers are connected to the end beams by means of hinges with two degrees of freedom, and the orthizing elements are placed on the axes of the rollers and are made in the form of thin-walled truncated cones with slots along the generatrices.
