Main beam connecting cross beam structure for semicircular main beam quay crane

Abstract

The invention discloses a main beam connecting cross beam structure for a semicircular main beam quay crane, which comprises a box-shaped structure penetrating through a semicircular main beam, and the length axis of the box-shaped structure is vertically intersected with the length axis of the semicircular main beam; the box-shaped structure comprises an upper panel, a lower panel, an inner side web plate and an outer side web plate; the upper panel and the lower panel both penetrate through the semicircular main beam; the inner side web is arranged on the outer side face of the semicircular main beam and between the inner side edge of the upper panel and the inner side of the lower panel, and the outer side web is arranged on the outer side face of the semicircular main beam and between the outer side edge of the upper panel and the outer side of the lower panel; and a connecting lug plate is arranged on the upper surface of the upper panel. The connecting reliability between the connecting cross beam and the semicircular main beam is improved.

Description

technical field [0001] The invention relates to a main girder connecting crossbeam, more specifically, relates to a main girder connecting crossbeam structure for a semicircular main girder quay bridge. Background technique [0002] to combine figure 1 and figure 2 As shown, the semi-circular main girder quay bridge is a device for loading and unloading the container 3 on the wharf or ship by means of a trolley reciprocating on the track on the semi-circular main girder 1 . In order to maintain a certain pre-tightening force for the hoisting wire rope without interfering with the semicircular main beam 1, the tail of the semicircular main beam 1 needs to extend left and right like wings to connect with the semicircular main beam 1. Then arrange the hanger mechanism 5 on the connecting beam 4, each time the lifting and lowering of the spreader 2, the hanger mechanism 5 needs to cooperate with the movement, resulting in alternating loads, resulting in complex and harsh stre...

Problems solved by technology

In order to maintain a certain pre-tightening force for the hoisting wire rope without interfering with the semicircular main beam 1, the tail of the semicircular main beam 1 needs to extend left and right like wings to connect with the semicircular main beam 1. Then arrange the hanger mechanism 5 on the connecting beam 4, each time the lifting and lowering of the spreader 2, the hanger mechanism 5 needs to cooperate with the movement, resulting in alternating loads, resulting in complex and harsh stress conditions on the connecting beam 4, semicircular Cracks will appear at the intersection of the main beam 1 and the connecting beam 4, so the reliability of the connection design between the connecting beam 4 and the semicircular main beam 1 is very high
