The utility model discloses a detachable roller mechanism of a marine rail crane, which comprises a roller, a bracket, a bearing seat, a bearing, a shaft and a positioning sleeve. One side of the bearing seat is fixedly connected with the bracket, a baffle is fixed at the opening of the bearing seat, a bearing sleeve is fixed on the shaft, and the bearing is fixed on the bearing seat through the bearing support, and a positioning is arranged between the bearing and the bearing seat. The sleeve and the roller sleeve are arranged at the end of the shaft. The utility model greatly improves the arrangement and installation of bearings and baffles and the positioning of axles. The arrangement and installation of bearings are improved from being installed on rollers to being installed on brackets, and the baffle is installed on the outer side of brackets. A positioning sleeve is added between the bearing seat and the bearing, and the positioning sleeve is also fixed on the axle seat by screw. The outer ring of bearings and the inner ring of the positioning sleeve are transitionally matched. The roller is inserted after passing through the bearing, and is connected and fixed with the roller by two long screw, so that the shaft and the roller rotate together. The installation structure is safe, reliable, easy to disassemble and maintain.

一种船用轨道起重机可拆卸式滚轮机构
本技术涉及船用轨道起重机
,具体涉及一种船用轨道起重机可拆卸式滚轮机构。
技术介绍
如图1所示,图中标号:挡板、滚轮、衬套、支架、轴、卡簧、螺钉、轴承、轨道齿条。现有的滚轮机构在安装时,衬套3与支架4采用焊接方式固定,轴5和支架4通过螺栓连接固定,轴5不转动,轴承8是安装在滚轮2内部,挡板1安装在滚轮端面通过螺钉7连接固定并贴近轨道立面,轴5与轴承8采用卡簧连接。此种安装结构在滚轮支架安装上轨道9以后,由于挡板距离轨道立面太近,导致没有空间进行拆卸操作(无法拆除挡板上的螺钉),即便拆除了挡板,也很难将卡簧拆掉以及将轴从轴承中拆掉。这样,会使得滚轮机构安装好后,拆卸、维护保养均不便。
技术实现思路
