The embodiment of the invention relates to a one-machine multi-point driving mechanism for a railway turnout, and the mechanism comprises a pull rod which at least comprises a first pull rod and a second pull rod, a supporting seat, and long connecting rods; the pull rod is hinged to at least two traction points of two switch rails, and one end of the first pull rod is used for being connected with switch equipment; the supporting seat comprises a first supporting seat and a second supporting seat; a T-shaped connecting rod is hinged to the other end of the first pull rod and hinged to the supporting seat. The long connecting rods comprise a first long connecting rod and a second long connecting rod, one ends of the long connecting rods are hinged to the first T-shaped connecting rod, and the other ends are hinged to the second T-shaped connecting rod. In the embodiment, a parallelogram mechanical structure which is stable in force transmission is formed through the T-shaped connecting rods and the long connecting rods, stress is even, and a labor-saving structure is formed. And the accuracy of displacement linear output and actual stroke value of the switch rail wrenched by the pull rod at each traction point is met. One-machine multi-point driving is realized, the operation is smooth, the number of turnout switch equipment is reduced, and the electric service maintenance cost is reduced.
本公开实施例是关于一种铁路道岔用一机多点驱动机构,包括:拉杆,拉杆至少包括第一拉杆和第二拉杆,拉杆与两个尖轨的至少两个牵引点铰接,第一拉杆的一端用于和转辙设备连接;支撑座包括第一支撑座和第二支撑座;T形连杆和第一拉杆的另一端铰接,T形连杆和支撑座铰接;长连杆包括第一和第二长连杆,长连杆的一端分别与第一T形连杆铰接,另一端分别与第二T形连杆铰接。本实施例中,通过T形连杆与长连杆形成传力平稳的平行四边形力学结构,受力均匀,构成省力结构。满足各牵引点处拉杆扳动尖轨的位移线性输出及实际动程值的准确性。实现一机多点驱动,运行流畅,减少了道岔转辙设备的数量,降低了电务养护维修成本。
