Dual-beam movable container loading bridge

Abstract

The invention relates to a dual-beam movable container loading bridge. An upper beam is fixedly connected with the tops of a front doorframe and a rear doorframe, the lower plane of the upper beam is provided with rails, a first upper dolly and a second upper dolly are respectively installed on the front part and the rear part of the upper beam, and the lower parts of the front doorframe and the rear doorframe are respectively connected with a running gear; a lower beam is equipped with adjustable longitudinal and transverse rollers and realizes up-and-down motion under the driving of a driving mechanism and two sets of pulley blocks; the first upper dolly and the second upper dolly are respectively mounted on the rails located at the front part and the rear part of the upper beam and respectively equipped with a lifting mechanism and a container spreader; a lower dolly is mounted on a rail of the lower beam and is equipped with an operating mechanism; and a lower beam moving mechanism and the pulley blocks are mounted on the top of a crossbeam between the front doorframe and the rear doorframe. The dual-beam movable container loading bridge is applicable to an ultra-large container carrier and has the advantages of a simple structure, definite stress, light weight, high efficiency, capacity of realizing loading and unloading of three containers in a working cycle, conservation of investment and energy and substantial improvement of operation benefits.

Description

technical field [0001] The invention relates to a container cargo loading and unloading operation system on a container ship, in particular to a container loading and unloading bridge for loading containers on the shore to the container ship or on the contrary, that is to quickly unload the containers on the container ship to the shore through continuous operations. Background technique [0002] Typically, a large number of containers are loaded and unloaded onto a container ship by a general-purpose shore-to-shore container crane. This type of container loading and unloading bridge has repetitive actions and low efficiency during operation. The loading and unloading equipment has complex and huge structure, expensive construction, complicated installation, and heavy wheel pressure on the wharf, so that the construction cost of the wharf is high. [0003] In view of this, seeking a new type of equipment to replace the shore container crane has become the goal pursued by tech...
