Abstract

The invention belongs to the technical field of container lifting appliances, and discloses a foldable container combined lifting appliance with a single and double row operation mode and controlled by a series, parallel or series-parallel mechanism. The foldable container combined lifting appliance comprises a first lifting appliance and a second lifting appliance, the first lifting appliance andthe second lifting appliance are both provided with telescopic structures, are adjustable in length and are connected through an adjusting mechanism; through multi-degree-of-freedom rotation of the adjusting mechanism, the distance between the first lifting appliance and the second lifting appliance is adjusted to be equal to the width sum of two containers or the sum of one container, the lifting error is adjusted, and accordingly, lifting of containers under different working conditions is achieved. According to the foldable container combined lifting appliance, on the premise that the bridge crane structure is not changed, double-row container operation can be conducted, in addition, single-row container operation can be conducted through folding, and especially, through the containerdigging operation, the operation efficiency is improved; and in the single and double row operation mode switching process of the combined lifting appliance, transmission and supporting are conductedthrough the modes of special-shaped tooth contact, arc surface contact, molded surface contact and the like so that mode switching can be achieved, the smoothness in the mode switching process is improved, and the driving force is reduced.

Description

technical field [0001] The invention belongs to the technical field of container spreaders, and in particular relates to a foldable container combination spreader with single-row and double-row operation modes. Background technique [0002] Containers have standard dimensions and fixing methods, so they can be matched with any standardized means of transport during transportation. The use of containers to transport goods can realize the joint transportation from the sender to the receiver through shipping, railway and road without changing the container in the middle. The proportion of modern cargo transportation, especially long-distance transportation, is increasing. Following the containerization trend of cargo transportation, in order to improve the efficiency of container loading and unloading, especially the efficiency of container terminal loading and unloading operations, it is urgent to design and develop container spreaders capable of lifting two or more container...
