Embodiment Construction

[0059] Refer to the following Figure 1-10 The shore bridge 100 which concerns on one Embodiment of this invention is demonstrated.

[0060] With respect to the quay crane 100 of the present invention, the so-called sea side refers to the side closer to the shore, or the side closer to the container to be unloaded on the ship, and the so-called land side refers to the side opposite to the sea side , that is, the side farther away from the shore, or the side of the container to be unloaded on the ship.

[0061] figure 1 , 2 , The sea side in 7-10 is the right side of the paper, and the land side is the left side of the paper. image 3 ,5 The sea side in the book is the outer side of the paper, and the land side is the inner side of the paper. Figure 4 , 6 The sea side in the book is the inside of the paper, and the land side is the outside of the paper.

[0062] The quay bridge 100 has: a pair of sea-side columns 10; a sea-side upper beam 11, the sea-side upper beam 11 c...

Abstract

The invention provides a quay crane. The quay crane is provided with a pair of seaside stand columns, a seaside upper cross beam, a pair of landside stand columns, a landside upper cross beam, a front girder, a rear girder and a girder connecting mechanism; through the girder connecting mechanism, the front girder and the rear girder can move between a working state and a non-working state, in the working state, the front girder and the rear girder are connected and fixed to be in a horizontal state, in the non-working state, the rear girder descends horizontally, the front girder is raised in a manner that the first shaft rotates relative to the seaside upper cross beam and the second shaft rotates relative to the rear cross beam. The quay crane can effectively reduce the seaside wheel pressure and the landside wheel pressure.

Description

technical field [0001] The invention relates to a shore bridge. Background technique [0002] Quay crane (that is, quayside container crane) is a port mechanical equipment used for loading and unloading container ships at container terminals. With the development of large-scale ships, the quay bridge is required to have a higher operating height and greater outreach, so the quay bridge is also enlarged accordingly, and the wheel pressure of the quay bridge increases accordingly, which puts forward higher requirements for the carrying capacity of the wharf. requirements. Most of the existing wharves are old wharves, which do not have enough bearing capacity to support such a large quay bridge. [0003] Specifically, the existing quay bridges are all fixed rear girders. In the working state (the working condition of loading and unloading containers), the front girder and the rear girder are connected horizontally. and storm conditions), the front girder is raised. Accordin...
