Pendulum bob type travel switch and pipe pile transportation device

The utility model relates to a pendulum bob type travel switch and a pipe pile transportation device, which comprise a transportation belt for transporting workpieces, a bracket, a proximity switch, a reset pendulum bob and a trigger swing rod, the bracket is arranged on the side surface of the transportation belt, the upper part of the reset pendulum bob is provided with an adapter which is rotatably connected to the bracket, and the trigger swing rod is arranged on the adapter. The lower end of the trigger swing rod is connected to the reset pendulum bob, the upper end of the trigger swing rod is provided with a trigger part used for abutting against a workpiece, and the proximity switch is connected to the support and used for detecting the rotating position of the reset pendulum bob. According to the scheme, contact with the pipe die is achieved by triggering the swing rod, and accurate triggering is achieved; meanwhile, non-contact detection is carried out on the rotation angle of the reset pendulum bob
