实施例4
更具体的,如图2所示,所述绝缘滑车5包括滚轮组51、滚轮支架52和闭锁结构53;其中:
所述滚轮组51设置在所述滚轮支架52内部;
所述闭锁结构53设置在所述滚轮支架52顶部,与滚轮支架52形成可翻转连接;
所述绝缘滑车5通过所述滚轮支架52与所述支架主杆11固定连接。
在具体实施过程中,通过闭锁结构53将跨过绝缘滑车5的导线固定在所述滚轮组51上,防止施工工程中导线意外脱离支架,巩固了导线和滚轮组51的连接关系。
更具体的,所述闭锁结构53上设置有闭锁拉环531。
在具体实施过程中,闭锁拉环531为施工人员提供一个施力点,施工人员通过绝缘操作杆拉动闭锁拉环531便可实现闭锁操作。
在具体实施过程中,所述支架主杆11采用环氧树脂结构,其重量轻,方便施工人员的轻松的搬运和展放。
在具体实施过程中,在滚轮支架52上设置有挂钩,用于装设防风绳,可根据实际的施工环境在挂钩上装设防风绳,提高了支架在大风环境下的稳固性。
在具体实施过程中,支架还包括驳接套环和驳接管,通过驳接套环和驳接管可实现支架主杆11向上的伸长,使支架适用于高的被跨越物。
实施例5
在具体实施过程中,所述跨线支架的具体使用步骤为:
S1:将10kV绝缘伸缩型导线提升支架放置在被跨越物体两侧,使用水平尺测量支架水平度,在软基地面施工时还应使用固定地针、绝缘防风绳加强支架的稳定性,按实际跨越高度调整支架高度;
S2:使用绝缘操作杆拉开支架顶部绝缘滑车5的闭锁拉环531;
S3:使用绝缘操作杆将牵引用绝缘绳放入两侧支架;
S4:轻轻拉动绝缘绳将导线牵引过两侧绝缘滑车5;
S5:使用绝缘操作杆合上支架顶部绝缘滑车5的闭锁结构53;
S6:导线展放完毕后再拉开两侧闭锁拉环531完成导线的整体提升工作。
在具体实施过程中,本发明提供的跨线支架,施工人员通过操作杆可实现全地面作业,减少了人员高处作业的风险;导线不需要直接接触被跨越物,保证了施工时导线绝缘外皮不受破坏,也有效防止被跨越物倾覆、破损的问题;操作设计简单,不需要投入大量的人员去搬运和展放支架;运输便携,一般的厢式车都可以运输,皮卡车可考虑散件运输。
显然,本发明的上述实施例仅仅是为清楚地说明本发明所作的举例,而并非是对本发明的实施方式的限定。对于所属领域的普通技术人员来说,在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本发明权利要求的保护范围之内。
