Quay crane

Abstract

The invention discloses a quay crane. The quay crane comprises a door frame structure, a quay crane upper part structure and a driving device, wherein the door frame comprises a first land side standcolumn and a second land side stand column which are arranged at intervals in a first direction and a first sea side stand column and a second sea side stand column which are arranged at intervals inthe first direction, the first sea side stand column and the first land side stand column are arranged at intervals in a second direction, and the second sea side stand column and the second land sidestand column are arranged at intervals in the second direction; the quay crane upper part structure involves a land side upper cross beam and a sea side upper cross beam, wherein the land side uppercross beam is detachably connected with the first land side stand column and the second land side stand column in the first direction correspondingly; the sea side upper cross beam is connected with the upper side cross beam and is detachably connected with the first sea side stand column and the second sea side stand column in the first direction correspondingly; and the driving device is used for driving the quay crane upper structure to move relative to the door frame structure in a third direction, and the first direction, the second direction and the third direction are perpendicular to one another. According to the quay crane, the problem of the whole machine height during transportation can be solved.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a shore bridge. Background technique [0002] Quay cranes, also known as quayside container cranes, are equipment used to load and unload containers on ships on the shore. For example, the Chinese patent document whose publication number is CN107285208A discloses a kind of double main trolley quay bridge, on the girder of the quay bridge, there are two main trolleys, the main trolleys are used for loading and unloading ships, and the two main trolleys have their own independent The hoisting mechanism and the spreader, the two main trolleys operate independently, or the two main trolleys are connected to each other, the spreader is also connected to each other, and the two main trolleys are combined to run. [0003] The quay crane manufacturer delivers the quay crane as a whole machine. The whole machine transportation has many advantages compared with the parts transported to the...
