The single-arm double-connecting-rod push-pull mechanism for the tooth track fork comprises electric push rods with fixed positions, and the electric push rods are vertically arranged on the outer sides of a left straight sliding rail and a right straight sliding rail in a vertical state in parallel; push-pull force output by the electric push rod in a vertical telescopic mode drives the slider-crank mechanism to swing, and swing power of the slider-crank mechanism passes through the horizontally-arranged middle connecting rod and the tail end left connecting rod and the tail end right connecting rod which are obliquely arranged in parallel at intervals and finally pushes the left force-bearing sliding plate and the right force-bearing sliding plate to complete rack rail transfer operation. The single-arm double-connecting-rod push-pull mechanism with the crank sliding block is adopted, and the problems that an existing overall flexible tooth track fork is large in occupied space, and stress cannot meet the requirement are solved; the rail transfer operation requirement of the overall flexible tooth rail turnout is met, the operation space is small, the assembly cost is low, stress meets the requirement, and the safety risk is reduced.
提供一种齿轨道岔用单臂双连杆推拉机构,包括位置固定的电动推杆,电动推杆竖直平行设置于竖直状态下的左、右直滑轨外侧;电动推杆竖直伸缩输出的推拉力驱动曲柄滑块机构摆动,曲柄滑块机构的摆动动力经水平设置的中间连杆、以及倾斜间隔平行设置的两个末端左、右连杆后,最终分别推动左、右承力滑板完成齿轨的变轨作业。本发明采用带曲柄滑块的单臂双连杆推拉机构,解决现有整体可挠式齿轨道岔占用空间大,受力无法满足需求的问题;满足整体可挠式齿轨道岔的变轨作业要求,操作空间小,装配成本低,受力满足需求,降低安全风险。
