According to the multi-connecting-rod transmission mechanism for the current collecting frame and the control method of the multi-connecting-rod transmission mechanism, compared with a three-connecting-rod transmission mechanism, a four-connecting-rod transmission mechanism and other transmission mechanisms in the prior art, amplification of transmission torque is achieved through the multi-connecting-rod structure, and the time for lowering a current collecting rod is effectively shortened; through multiple times of rotation pair transition, the stroke of the air cylinder is reduced; meanwhile, the trolley pole is in movable contact connection with the connecting rod mechanism, rotation is more flexible, the trolley pole is not limited by resistance of an air cylinder in the vehicle running process, the trolley pole can flexibly swing up and down along with the wire net, stable net touching force is kept, and wire disengaging is not prone to occurring; the overall height of the connecting rod structure is reduced, and the height limiting problem of the roof is solved; an emergency return device is arranged, so that the danger caused by accidental off-line is avoided; in addition, the axial length of the lead screw assembly is adjustable, and stable net touching force can be provided for road sections with different wire net heights; the trolley pole can be separated from the transmission connecting rod mechanism and can rotate to the position close to the ground, personnel do not need to climb to a car roof, and maintenance is convenient.

    本发明提供一种用于集电架的多连杆传动机构及其控制方法,相较于现有技术中的三连杆、四连杆等传动机构,通过采用多连杆结构实现传递转矩的放大,有效缩短了集电杆降杆的时间;通过多次的转动副过渡,从而减少气缸行程;同时集电杆与连杆机构活动接触连接,转动更加灵活,车辆行驶过程中集电杆不受气缸阻力的限制,能够灵活的随着线网上下摆动,保持稳定的触网力,不易脱线;把连杆结构的整体高度拉低,解决车顶限高的问题;通过设置紧急回位装置,避免因意外脱线造成的危险;此外,丝杆组件轴向长度可调,能够为不同线网高度的路段提供稳定的触网力;集电杆可以与传动连杆机构分离,转动至接近地面位置,人员不必爬到车顶,即方便维护和保养。
