Description

一种用于组装输电塔的抱杆 技术领域
本发明涉及一种抱杆，尤其涉及一种用于组装输电塔的抱杆。
背景技术
抱杆是吊装设备时使用的一种起重工具。抱杆主要有单体柱式和格构式两种，在同样承载能力下格构式抱杆比单体柱式自重轻，纵向稳定性好，抗弯强度大，侧向变形小。所以格构式抱杆应用更加广泛。
现有的格构式抱杆用材料普遍使用有钢制标准节及铝制标准节。钢材密度大，用其制成的抱杆较重，不利于装拆和搬运，特别是在地势复杂的山区和环境恶劣的地区的安装和搬运更加困难。铝材密度相对较小，但制成的抱杆强度低，容易损坏，且铝材格构式抱杆需要用法兰连接，连接后重量增大同样不便于安装和搬运；随着材料科学的进步，玻璃纤维增强树脂基复合材料即玻璃钢逐渐应用于抱杆，但玻璃钢抱杆存在如下缺点：
(1)弹性模量低：玻璃钢的弹性模量比钢小5倍，刚性较低。
(2)耐温期短：玻璃钢一般不能在高温下长期使用，例如通用聚酯玻璃钢一般只在100℃以下使用；通用型环氧玻璃钢仅在60℃以上，且强度明显下降。
(3)易老化：在紫外线、风沙雨雪、化学介质、机械应力等条件下耐老化性能差。

第七步、如图11所示，调整抱杆使其向起吊面倾斜；使用起重组件21 完成塔身15的吊装工作；
通过抱杆和撑杆配合使用，解决了特殊地形组塔施工困难的问题。
作为一种实施方式，撑杆为光滑圆柱，没有突出障碍，提升顺畅，便于生产与现场搬运，提高施工效率。
第八步、如图12所示，提升抱杆至塔顶16米处并调整抱杆使其向起吊面倾斜0.4至0.6米；使用起重组件21吊装地线支架23；
第九步、如图13所示，在地线支架23上设置滑轮，使用起重组件21上的驱动绳通过地线支架23上的滑轮吊装横担16；
第十步、铁塔吊装完毕后，通过绞磨机22驱动承托绳19调整抱杆使其竖直设置，并在抱杆根部设置拉绳；拉绳另一端与设置在地面上的电机相连；
通过牵引设备提升抱杆上升后，拆除承托绳19、拉线18和滑轮后通过抱杆升降组件26下降抱杆后，拆除撑杆5；拉紧拉绳，将抱杆引出塔身。
作为一种实施方式，如图15所示，在第三步中，腰环28为顶点设有与抱杆轴向垂直的连板27的长方形框架；
连板27设有与其表面垂直设置的孔，孔内设有与塔座17相连的绳索，
长方形框架内设有与抱杆固定的连接件。
作为一种实施方式，如图14所示，在第五步中，撑杆安装件20设有圆环固定件24、设置在圆环固定件24侧面且与其横截面垂直的联板25；
圆环固定件24内设有与塔座17配合固定的连接件；
联板25设有与其表面垂直设置的空心圆轴；空心圆轴与底部连接金具11通过双头螺栓固定。
圆环固定件24由两个半圆连接件通过螺栓固定；两个半圆连接件连接处分别设有与其横截面垂直的连接板，连接板通过螺栓连接。
撑杆安装件20设置在塔座17的四个侧面上且位于其顶端轴向向下1.5 米处。
作为一种实施方式，在第六步中，抱杆始终保持垂直状态且其高度高出塔座17高度19—20米；
固定好的抱杆与承托绳19夹角不大于45度；撑杆5与水平面的夹角在10至15度之间。
由于抱杆其地拉线与水平面夹角不大于45°，因此，可以在高低差变化大的山地、半山甚至危崖地带使用。
作为一种实施方式，在第六步至第九步中，起重组件21设有绞磨机22、与绞磨机22相连的驱动绳、设置在铁塔下端和抱杆顶端的滑轮以及固定吊件的绳套26。
