铁塔导线横担挂点连接改进结构
摘要：
本实用新型涉及一种铁塔导线横担挂点连接改进结构，包括两个导线挂线角钢，所述导线挂线角钢对称间隔设置于铁塔横担上，所述导线挂线角钢的挂点孔之间铰接有可前后摆动的UB挂板，所述UB挂板下端铰接有可左右摆动的PS挂板，所述UB挂板的长度增大至其上端的铰接轴中心线与下端的铰接轴中心线之间的距离大于导线挂线角钢的挂点孔中心线与下边缘之间的距离，所述UB挂板的宽度增大至比导线挂线角钢之间的距离小1~5mm。本实用新型采用尺寸更大的UB挂板，使PS挂板摆动时碰触导线挂线角钢的角度增大，即增加了绝缘子的摇摆角，减低了PS挂板与导线挂线角钢的撞击率，进而使PS挂板抗风力的能力增强，提高了输电线路的可靠性。
摘要（英）：

The utility model relates to a tower wire cross-arm suspension connection modified structure comprising two wire-hanging steel angles which are symmetrically disposed on a tower cross-arm in a spaced manner. A UB-type hanging plate which can wing back and forth is hinged between suspension holes of the wire-hanging steel angles. A PS-type hanging plate which can swing side to side is hinged to the lower end of the UB-type hanging plate. The length of the UB-type hanging plate is increased so that a distance from a hinge pin center line of the upper end to that of the lower end is greater than a distance from a center line of the suspension holes of the wire-hanging steel angles to the lower edge; the width of the UB-type hanging plate is increased to be 1-5mm less than a distance between the wire-hanging steel angles. The larger UB-type hanging plate is adopted, the angle at which the PS-type hanging plate touches the wire-hanging steel angles is enlarged when the PS-type hanging plate swings, swing angle of an insulator is enlarged, chances that the PS-type hanging plate collides with the wire-hanging steel angles are slimmed, wind resistance of the PS-type hanging plate is improved, and reliability of a power transmission line is improved.
