The invention relates to a positioner for an urban rail transit overhead line system. The positioner comprises a fixed seat; the fixed body is vertically arranged and is rotationally arranged with the fixed seat; the two connecting rods are arranged in parallel, and the end parts of the two connecting rods are riveted with the top and the bottom of the fixed body respectively; the positioning body is vertically arranged and is riveted with the other ends of the two connecting rods; the positioning wire clamp is fixed at the bottom of the positioning body and clamps the contact wire; the fixing seat is connected with the positioning pipe located above the fixing seat, the fixing body is hinged to the fixing seat, that is, the fixing body can rotate relative to the fixing seat, the fixing body, the two connecting rods and the positioning body form a parallelogram structure, the bottom of the positioning body is provided with two positioning wire clamps, and the positioning wire clamps are used for clamping a contact wire; due to the design of the parallelogram structure, when a train passes through a positioning point, under the action of the lifting force of a pantograph, the positioner freely moves up and down within a certain range, no hard point is generated, and good wind stability is achieved.
本发明是一种城市轨道交通接触网用定位器,包括:固定座;固定本体,其竖直与固定座转动设置;两连杆,其平行设置,其端部分别与固定本体的顶部、底部铆接;定位本体,其竖直设置,其与两连杆的另一端铆接;定位线夹,其固定在定位本体底部,并夹紧接触线;固定座与位于其上方的定位管连接,固定本体与固定座铰接,即固定本体能够相对于固定座发生转动,固定本体、两连杆、定位本体构成平行四边形结构,定位本体底部设置有两个定位线夹,定位线夹的作用是夹紧接触线;该平行四边形结构的设计,使得当列车通过定位点时,在受电弓抬升力作用下,定位器在一定范围内上下动作自如,不产生硬点,且具有良好的风稳定性。
