The invention relates to the technical field of electrified railway traction power supply equipment, and provides a reinforced durable integral dropper which comprises a wire locking device, two reset springs are fixedly connected to the inner wall of the wire locking device, and one end of each reset spring is fixedly connected with a rectangular wire clamping body. The top of each rectangular wire clamping body is fixedly connected with an upper contact plate, the outer wall of each rectangular wire clamping body is hinged to a hinge piece, the outer wall of each hinge piece is fixedly connected with a lower contact plate, and the outer wall of each hinge piece is fixedly connected with a force application handle. According to the technical scheme, the force application handle is pressed, when the two clamping bodies on the rectangular wire clamping bodies touch the horizontal wire circular pipe, the two rectangular wire clamping bodies just seal and clamp the horizontal wire circular pipe, one end of the dropper wire can be firmly fixed in the horizontal wire circular pipe, and the fixing effect is achieved; the problems of impact load, strand stress concentration and energy dissipation caused by impact load between pantographs and catenaries in the prior art can be effectively solved.
本发明涉及电气化铁路牵引供电设备技术领域,提出了一种加强耐用型整体吊弦,包括锁线器,所述锁线器的内壁固定连接有两个复位弹簧,两个所述复位弹簧的一端均固定连接有矩形卡线体,两个所述矩形卡线体的顶部均固定连接有上接触板,所述矩形卡线体的外壁铰接有铰接件,所述铰接件的外壁固定连接有下接触板,所述铰接件的外壁固定连接有施力手柄。通过上述技术方案,按动施力手柄,当矩形卡线体上的两个卡体碰到卧线圆管时,两个矩形卡线体刚好完成对卧线圆管的封卡,吊弦线的一端便会被牢牢的固定于卧线圆管内,达到固定的效果,解决了现有技术中的能够有效地解决弓网之间冲击载荷造成的冲击载荷,线股应力集中和能量耗散的问题。
