  • Patent number: 10662005
    Abstract: A temporary storage and separation device for the wheels on the track line includes a main body bracket, a rotating mechanism, a turntable, a first connection rod, a second connection rod, a third connection rod, a fourth connection rod, a first blocking lever, a second blocking lever, a third blocking lever and a fourth blocking lever. The temporary storage and separation device for the wheels makes use of the turntable to drive the four blocking levers disposed at different positions to be extended or contracted to realize separation and temporary storage of the wheels in a transfer process; and meanwhile, photoelectric switches, reversible motors and a control unit cooperate with the temporary storage and separation device for the wheels to realize reversible transfer on the wheel transfer track line.
