Travelling mechanism for translation type crane and translation type crane

Abstract

The invention discloses a travelling mechanism for a translation type crane and the translation type crane. The travelling mechanism for the translation type crane comprises a travelling motor as wellas a first side plate and a second side plate which are opposite and are arranged in a spaced mode, wherein the travelling motor drives a travelling rotary shaft to rotate through a travelling speedreducer; the travelling rotary shaft is rotatably connected to the first side plate through a first bearing; the travelling rotary shaft is rotatably connected to the second side plate through a second bearing; the travelling rotary shaft is fixedly connected with a gear; the gear is positioned between the first side plate and the second side plate; the side, towards the second side plate, of thefirst side plate is rotatably connected with a first roller; the side, towards the first side plate, of the second side plate is rotatably connected with a second roller; and the first roller and thesecond roller are arranged in the spaced mode. The travelling mechanism can reduce impact damages borne on the travelling speed reducer, so that the travelling speed reducer is protected, and therefore, the damage rate of the speed reducer is reduced.

Description

technical field [0001] The present invention generally relates to the field of marine machinery, specifically to the field of marine cranes, and in particular to a traveling mechanism for a translational crane and a translational crane. Background technique [0002] With the rapid development of international trade, the logistics industry is also developing rapidly, and many goods are transported by sea. As a result, the shipbuilding industry in various countries has also risen, and marine cranes have also developed rapidly as an effective tool for cargo loading and unloading. The translational crane has many advantages such as simple working method, convenient operation, small space occupation, wide application, and low production cost, so more and more bulk carriers, container ships, chemical tankers, etc. will be equipped with it. [0003] Compared with the traditional slewing jib crane, each ship only needs to be equipped with one translational crane to take into accoun...

AI Technical Summary

Problems solved by technology

But at the same time, the shortcomings of the translational crane are also obvious. Because the translational crane is narrow and long, and the suspension is installed on the opposite side of the deck, the ship will shake more obviously when encountering wind and waves during navigation.

[0004] The reducer of the existing traveling mechanism of a translational crane is directly connected to the transmission gear, and the reducer part has no other protection, so the reducer is easily damaged by impact when shaking
