The invention relates to the technical field of railway special tools, and discloses an electric crank for a railway point switch machine. The electric crank comprises a shell, a driving motor and a storage battery, the driving motor is fixedly mounted on the lower surface of the interior of the shell through a rack, the storage battery is fixedly mounted on the inner wall of the shell, the outputend of the driving motor is fixedly connected with a rocker through a coupling, the other end of the rocker penetrates through the side wall of the shell and extends outwards, the rocker is rotationally connected with the side wall of the shell, the end of the rocker is sleeved with a matched rotating cylinder, the end of the rotating cylinder is fixedly connected with a matching end matched witha rotating shaft of the point switch machine, sliding blocks are symmetrically and fixedly connected to the inner wall of the rotating cylinder, an annular groove is formed in the outer rod wall of the rocker, the sliding blocks are slidably connected with the annular groove, and a rotary positioning mechanism is installed between the rotating cylinder and the rocker. The electric crank and the rotating shaft of the point switch machine can be conveniently and quickly butted and clamped, so that the working efficiency is effectively ensured.

    本发明涉及铁路专用工具技术领域,且公开了一种铁路转辙机用电动摇把,包括壳体、驱动电机和蓄电池,驱动电机通过机架固定安装在壳体内部的下表面,蓄电池固定安装在壳体的内壁上,驱动电机的输出端通过联轴器固定连接有摇杆,摇杆的另一端贯穿壳体侧壁并向外延伸,且摇杆与壳体侧壁转动连接,摇杆的端部套设有匹配的转筒,且转筒的端部固定连接有与转辙机转轴相适应的配合端,转筒的内壁对称固定连接有滑块,摇杆的外杆壁上开设有环形槽,且滑块与环形槽滑动连接,转筒与摇杆之间安装有转动定位机构。本发明方便电动摇把与转辙机的转轴进行快速对接卡合,从而有效保证工作效率。
