Abstract

The invention provides a differential speed reducing device, a driving mechanism for a crane and a quayside container crane, and relates to the technical field of cranes. The differential speed reducing device comprises a first planet gear system; the first planet gear system comprises a first gear ring, a first center gear, a first planet gear and a first planet carrier; the first planet gear isengaged with the first gear ring and the first center gear; the first planet carrier is connected with the first center gear; the differential speed reducing device further comprises a second planet gear system, a third planet gear system and a fourth planet gear system; the first gear ring is in transmission connection with a second gear ring; the second gear ring is in transmission connection with a third gear ring; and the third gear ring is in transmission connection with a fourth gear ring. The differential speed reducing device, the driving mechanism for the crane and the quayside container crane are low in use and maintenance cost.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a differential speed reduction device, a driving mechanism for a crane and a shoreside container crane. Background technique [0002] With the rapid development of global shipping, the requirements for the loading and unloading efficiency of the quay container crane are getting higher and higher. The loading and unloading efficiency of the traditional single-box 40-foot quay container crane has reached a technical bottleneck. In order to break through the bottleneck, double 40-foot shore-to-shore container cranes appeared, and the popularity rate is increasing year by year, which is likely to replace them. [0003] At present, the double 40-foot quayside container crane has two sets of hoisting mechanisms and one set of operating mechanisms to drive, that is, the layout of hoisting mechanism 1 + hoisting mechanism 2 + trolley operating mechanism, each mechanism is independent, and...
