Description

Lifting girder shoreside bridge shearing-resistant protection device and shoreside bridge Technical Field The invention relates to the field of shore bridges, in particular to the field of girder connecting structures. Background Quay bridges, also known as quay container cranes, are devices used to load and unload containers on container ships on the quay side. The whole machine transportation can fully utilize the advantages of manufacturer sites, technologies, personnel and equipment to finish the installation and debugging work of the shore bridge, all the problems can be properly solved at the manufacturer, the manufacturing period is reduced, the debugged shore bridge can be put into use after the whole machine transportation is carried to the wharf, the time for occupying a user wharf to assemble or debug is reduced, and the timely delivery and use of the shore bridge are ensured. However, the whole shore bridge is transported generally through waterways, and sometimes encounters barriers with height limitation such as bridges, cables and the like, so that transportation traffic is affected. At present, a lifting type shore bridge can solve the problem of the height of the whole machine in the transportation process, namely, the height of the whole machine is reduced during transportation so as to pass through an obstacle, and the original height is recovered after the shore bridge reaches a user dock, so that the shore bridge works normally. As disclosed in chinese patent CN110342406B, a shore bridge structure is disclosed, in which a land-side upper beam is detachably connected to a first land-side column and a second land-side column, and a sea-side upper beam is detachably connected to the first sea-side column and the second sea-side column, respectively, and a pair of flanges are detachably connected together by bolts, so as to realize a disassembly structure. However, the inventor has found that such a bolt flange structure for achieving a detachable connection is prone to cause safety problems when the bolts fail, and needs to be solved. Disclosure of Invention The invention aims to provide a lifting girder shore bridge shearing protection device which can effectively solve the safety problem caused by bolt failure. The lifting girder shoreside bridge shearing protection device comprises a shearing block, a pair of baffles and a connecting component, wherein the shearing block simultaneously stretches into the first through hole and the second through hole, the pair of baffles are arranged on two sides of the shearing block on the axis, and the connecting component penetrates through the baffles and the shearing block to fasten the baffles and the shearing block.
