Description

一种折臂式可伸缩回转起重机
技术领域
本发明涉及回转起重机领域，具体是一种折臂式可伸缩回转起重机。
背景技术
回转起重机用于垂直提升和水平搬运重物在船舶上应用广泛，目前回转起重机的吊臂有固定长度的，此类回转起重机智能吊取固定范围内的物品，为了增加吊取范围，往往通过增加起重机的臂长来实现；也有吊臂做成可伸缩的，此类吊臂伸缩回转起重机的吊取范围也有一定限制，在增大吊取范围的同时，也增大了自身占用船舶甲板有限且宝贵的空间，使船上的活动空间缩小。
发明内容
本发明的目的就是为了解决现有的回转起重机吊取范围不足的问题，提供一种折臂式可伸缩回转起重机使吊取范围大大增加。
本发明的具体方案是：一种折臂式可伸缩回转起重机，包括底座，底座上装有回转座，回转座顶部铰接有吊臂，吊臂顶端铰接有滑轮，滑轮上通过吊绳装有吊钩，回转座上装有驱动吊钩升降的马达，所述回转座包括底部的回转台，所述吊臂包括一级吊臂，回转台上铰接有油缸A，油缸A的活塞杆与一级吊臂底面铰接，一级吊臂顶端铰接有二级吊臂，一级吊臂底面还铰接有油缸B，油缸B的活塞杆与二级吊臂底面铰接，二级吊臂内套装有三级吊臂，二级吊臂侧面固定装有油缸C，油缸C的活塞杆顶端与三级吊臂固定连接，一级吊臂顶端还铰接有一导轮，所述吊绳通过滑轮和导轮与马达连接。
本发明相比于现有回转起重机具有以下优点：一级吊臂和二级吊臂均可上下摆动，使吊臂更加灵活，吊取范围增大，二级吊臂内套装三级吊臂，通过油缸控制三级吊臂伸缩，进一步加大了吊取范围。
附图说明
图1是本发明结构主视图；
图中：1-底座，2-回转台，3-马达，4-吊绳，5-油缸A，6-一级吊臂，7-油缸B，8-导轮，9-二级吊臂，10-油缸C，11-三级吊臂，12-滑轮，13-吊钩。
具体实施方式
参见图1，本实施例包括底座1，底座1上装有回转座，回转座顶部铰接有吊臂，吊臂顶端铰接有滑轮12，滑轮12上通过吊绳4装有吊钩13，回转座上装有驱动吊钩13升降的马达3，所述回转座包括底部的回转台2，所述吊臂包括一级吊臂6，回转台2上铰接有油缸A5，油缸A5的活塞杆与一级吊臂6底面铰接，一级吊臂6顶端铰接有二级吊臂9，一级吊臂6底面还铰接有油缸B7，油缸B7的活塞杆与二级吊臂9底面铰接，二级吊臂9内套装有三级吊臂11，二级吊臂9侧面固定装有油缸C10，油缸C10的活塞杆顶端与三级吊臂11固定连接，一级吊臂6顶端还铰接有一导轮8，所述吊绳4通过滑轮12和导轮8与马达3连接。
