Problems solved by technology

[0002] With the development of my country's foreign trade transportation, the throughput of each terminal has increased sharply. Many container gantry cranes, which are the main yard machinery of the terminal, no longer meet the new stacking operation requirements in terms of working height.
At present, in order to improve the storage capacity of the yard, most of the terminals will re-purchase new cranes with a stacking capacity of "four to five" or higher, but the purchase of new crane equipment will increase the input cost of the terminal. thereby reducing the economic benefits of the terminal

Abstract

The invention discloses a height increasing tool for a container gantry crane. The height increasing tool comprises a height increasing base, wherein the height increasing base comprises a rectangularsupporting frame; four right-angled bottoms of the rectangular supporting frame are equipped with four supporting legs; the upper parts of the two ends of the rectangular supporting frame are separately equipped with connecting supporting bases which are fixedly connected with crane supporting legs of a crane to be subjected to height increasing; each end of the rectangular supporting frame is equipped with two connecting support bases; the bottom of each supporting leg is equipped with a jacking mechanism for jacking the height increasing base; each jacking mechanism comprises a jacking hydraulic cylinder, and a plurality of jacking blocks which are sequentially inserted are arranged between the piston rod of the jacking hydraulic cylinder and the bottoms of the supporting legs. The height increasing tool for the container gantry crane disclosed by the invention can be repeatedly utilized, long sides of the rectangular supporting frame consist of a plurality of supporting column sections, and adjacent supporting columns are connected through a flange. The height increasing tool can be freely assembled for use according to different models and different dimensions to be subjectedto heat increasing, so that cost is reduced for production.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a height-increasing tool and a height-increasing method for a container gantry crane. Background technique [0002] With the development of my country's foreign trade transportation, the throughput of each terminal has increased sharply. Many container gantry cranes, which are the main yard machinery of the terminal, no longer meet the new stacking operation requirements in terms of working height. At present, in order to improve the storage capacity of the yard, most of the terminals will re-purchase new cranes with a stacking capacity of "four to five" or higher, but the purchase of new crane equipment will increase the input cost of the terminal. Thereby reducing the economic benefits of the terminal. [0003] Therefore, in order to cooperate with the realization of the height increase of the container gantry crane, it is an urgent problem to be solved to design a safe and fas...
