专利说明:

The invention relates to an overhead transport engineering, in particular to units of a mobile connection of the span and end beams of bridge cranes used in nuclear power plants in seismic zones.
The known node of the mobile connection of the span and end beams of the bridge crane, contains axes located one above the other, the lower of which is installed in bearings (USSR Authority Certificate No. 397461, class B 66 C 17/00, 14.06.72
The purpose of the invention is to increase the reliability of the node by reducing the dynamic loads from seismic vibrations.
FIG. 1 shows the end beam, the section, and the span beam, side view; in fig. 2 is a section A-A in FIG. 1; FIG. 3 is a section BB in FIG. 2; in fig. 4 - location of t g inside the span beam; in fig. 5 - location of one gigi inside the span beam.
The node of the movable joint of the span 2 and end 1 of the bridge crane beams contains axes 3 and 6, located one above the other and mounted by bearings B, while the upper axis 3 is installed in elongated and end beams made elongated, x

horizontal and vertical windows 11 and 12 respectively, and the lower axis 6 is passed through the holes 13 made in the span beam and suspended to the upper axis 3 located in spherical bearings 4 by means of m 5. Between the upper axis 3 and The bottom wall 14 of the end beam 1 is mounted vertically mounted elastic supporting elements 7,
Elastic horizontal supports 8 and 9 are located offset by 90 in the lower part of the span beam 2.
The rods 5 are located inside the span beams and are interconnected by a bar 10. One of them can be placed inside the span beam.
Making a connection between the end 2 and span 1 crane beams movable in a horizontal plane (due to the hingedly floating suspension of the ends of the crane spans) allows the crane to operate in jarBHHX enhanced seismicity to prevent the occurrence of dynamic loads dangerous for structural strength.
Vertically mounted elastic support elements 7 compensate for the forces on the beams in the vertical plane.
