Problems solved by technology

[0003] At present, for port quay cranes (single-car quay cranes and double-car quay cranes), a set of lifting mechanisms is connected to a spreader, and a spreader can only be connected to a retractable spreader, and only one 40-foot container can be lifted at a time. (or two 20-foot containers), restricting the further improvement of productivity

Embodiment Construction

[0025] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] first reference Figure 1 ~ Figure 3 , shows the container crane of the present invention, which is suitable for the double 40-foot container operation of a set of hoisting mechanism quay bridge, and the container crane mainly includes a sea-side spreader upper frame structure 1, a land-side spreader upper frame structure 2, a split-close Mechanism 3, sea-side locking pin connection mechanism 4, land-side dislocation mechanism 5, sea-side electronic level 6, land-side electronic level 7, sea-side eccentric load correction mechanism 8 and land-side eccentric load correction mechanism 9. Wherein, the bottom of the sea-side spreader upper frame structure 1 has a movable double-case spreader, and the bottom of the land-side spreader upper frame structure also has a movable double-case spreader. In addition, the opening and closing mechanism 3 can be ar...

Abstract

The present invention provides a container crane, which comprises: a sea side lifting tool upper frame structure, wherein the bottom of the sea side lifting tool upper frame structure is provided with a moveable double container lifting tool; a land side lifting tool upper frame structure, wherein the bottom of the land side lifting tool upper frame structure is provided with a moveable double container lifting tool; a division and combination mechanism arranged on the one of the sea side lifting tool upper frame structure and the land side lifting tool upper frame structure; and a dislocation mechanism arranged on the other one of the sea side lifting tool upper frame structure and the land side lifting tool upper frame structure, wherein the division and combination mechanism can extend and be connected with the dislocation mechanism.

Description

technical field [0001] The invention relates to the field of port machinery, in particular to a container crane. Background technique [0002] Quayside container cranes are referred to as quayside cranes. The large-scale container transport ships, especially the development of post-Panamax ships, put forward newer and higher requirements for shore container cranes: first, improve the technical parameters of the cranes, speed up the speed parameters of the cranes, and increase the outreach and lifting height. The rated lifting capacity under the spreader is increased; the second is to develop and design a high-efficiency shoreside container handling system to meet the requirements of large-scale ships for crane productivity. [0003] At present, for port quay cranes (single-car quay cranes and double-car quay cranes), a set of lifting mechanisms is connected to a spreader, and a spreader can only be connected to a retractable spreader, and only one 40-foot container can be l...
