The invention relates to the technical field of electrified railway equipment, and discloses an automatic dropper adjusting and balancing device. The device comprises a cavity body; saw teeth are formed in the inner surface of the cavity; a telescopic rod is slidably connected into the cavity in a sleeving manner; grooves are formed in the two ends of the top of the telescopic rod; limiting blocksare rotationally connected into the grooves through mandrels; first springs are fixedly connected between the limiting blocks and the inner walls of the grooves; first connecting rods are rotationally connected to the bottom ends of the limiting blocks through connecting blocks; and the other ends of second connecting rods are rotationally connected to the two sides of the sliding shaft through connecting blocks. According to the automatic dropper adjusting and balancing device, automatic adjusting and positioning of the dropper are achieved through cooperation of large thrust of a pantographat the lower position of the contact line and the telescopic rod which is capable of ascending and positioning, vibration force borne by the dropper due to high-speed passing of the pantograph is reduced through the effect of a buffer sleeve, and the service life of the dropper is prolonged.
本发明涉及电气化铁路设备技术领域,且公开了一种吊弦自动调节平衡装置,包括腔体,所述腔体的内表面开设有锯齿,所述腔体的内部滑动套接有伸缩杆,所述伸缩杆顶部的两端开设有凹槽,所述凹槽的内部通过芯轴转动连接有限位块,所述限位块与凹槽内壁之间固定连接有第一弹簧,所述限位块的底端通过连接块转动连接有第一连接杆,所述第二连接杆的另一端通过连接块转动连接在滑动轴的两侧。该吊弦自动调节平衡装置,通过利用接触线较低处受到受电弓的推力较大和可上升定位的伸缩杆相配合,实现了吊弦的自动调节和定位,并通过缓冲套筒的作用,减轻了吊弦因受电弓高速通过而受到的振动力,提高了吊弦的使用寿命。
