Description

一种具有自锁功能的模块化大型球罐内部检测装置 技术领域
本发明属于大型球罐安全检测技术领域，具体涉及一种具有自锁功能的模块化大型球罐内部检测装置。
背景技术
目前，球罐作为石油、化工、冶金等重工业中常用的储存型压力容器，其具有体型大、占地面积较小、易操作及易管理等特点。但球罐是通过对不同规格的钢板焊接制成，其被用于行业的特殊性，焊缝的安全程度尤为关键，对焊缝的安全性需要提出一定的要求。不仅在球罐制造完成后需要检测，球罐达到一定使用年限后也需要检测。因此，球罐的定期检测成为一个关键的过程。但球罐的体积过于庞大，纯人工检测的工作量繁重，因此提出一个能对大型球罐内部进行安全性检测的装置具有重要意义。
在现有检测球罐技术中，大多数只采用固定中心轴一端的形式，其装置传动的稳定性较差；检测装置的安装过程繁琐，增加了工人的工作量，降低了工作效率；大多数装置并未考虑实际操作中的安全隐患，如在突发断电等情况下，不能保证检测仪器和工人的安全。

当本发明装置处于突发断电的情况下，所述第一长臂2-4-1、第二长臂2-4-2、第三长臂2-4-3、第四长臂2-4-4在重力的作用下有往下运动的趋势，由于本发明的装置带有蜗轮蜗杆结构，所述第一长臂2-4-1与所述第一蜗轮2-1-1固连，所述第二长臂2-4-2与所述第二蜗轮2-1-2固连，所以所述的四根长臂在蜗轮蜗杆自锁的特性下，不会突然下坠，保证了检测装置和工作人员的安全。
当所述活动销1-22在未安装的情况下，配合所述第二电机1-21转动，动力从所述第二小齿轮1-19传出，依次经过所述齿轮轴1-4、所述第二中心轴1-3-2、所述第三中心轴1-3-3、所述第四中心轴1-3-4、所述第五中心轴1-3-5、所述第六中心轴1-3-6到达所述蜗杆轴1-5，带动所述蜗杆轴1-5转动，使所述第一蜗轮2-1-1和所述第二蜗轮2-1-2转动，使所述第一长臂2-4-1、所述第二长臂2-4-2、所述第三长臂2-4-3、所述第四长臂2-4-4上下摆动，实现检测装置在所述大型球罐竖直平面内的上下运动。

所述上中心轴1-6下端设有连接头，见图12所示；所述下中心轴1-2上端设有连接孔，见图7所示；所述第一中心轴1-3-1的下端设有连接头，上端设有连接孔，见图8所示；所述齿轮轴1-4下端设有连接头，上端设有连接孔，中部齿轮上开孔，见图9所示；所述蜗杆轴1-5下端设有连接头，上端设有连接孔，见图10所示；所述蜗轮架1-13正面呈“U”字形，上面呈“工”字形，竖连接臂的上端面、下端面均开有轴座孔，所述蜗轮架1-13中间部位设有凸台，所述凸台中间开有通孔，所述凸台下端设有连接头，见图11所示。
所述第一连接件1-9呈两级凸台状，下端设有连接头，上端设有连接孔，中间部位开有通孔，见图15所示；所述第二连接件1-11中间部位呈扁平圆柱，所述扁平圆柱中间部位开有通孔，上端面设有连接头和连接孔，所述第二连接件1-11两边设有连接脚，所述连接脚上开有螺栓通孔，见图16所示；所述第一套筒1-8-1的下端设有连接头，上端设有连接孔，中间部位开有通孔，见图14所示；所述下套筒1-7上端开有连接孔，中间部位开有通孔，见图13所示；所述中套筒1-12上端设有连接孔，下端开有所述活动销1-22的安装孔，中间部位开有通孔，见图17所示。
以上示意性地对本发明进行了描述，该描述没有限制性，附图中所示 的也只是本发明的实施方式之一，实际的结构并不局限于此。所以，如果本领域的普通技术人员受其启示，在不脱离本发明创造宗旨的情况下，不经创造性的设计出与该技术方案相似的结构方式及实施例，均应属于本发明的保护范围。
