The invention relates to a magnetic suspension turnout small-displacement switch locking integrated device and a magnetic suspension turnout small-displacement switch locking integrated method, which use one driving unit to simultaneously complete small-displacement driving and locking operations, reduce the number of driving points and parts, improve the efficiency and reliability of turnout switching, and ensure the driving safety, and belongs to the field of magnetic suspension turnout manufacturing.

Background

CN 108589438A, name "a magnetic suspension turnout", including a fixed end pile beam, a movable end pile beam and a movable turnout beam disposed between the fixed end pile beam and the movable end pile beam, characterized in that the movable turnout beam includes a driving beam and at least two groups of driven beams, the driving beam is disposed close to the movable end pile beam, and the rotation center of the driving beam moves along the center line of the magnetic suspension turnout positive line position along with the change of the switching angle; the rotation center of each driven beam is a fixed rotation center arranged on the center line of the magnetic suspension turnout normal line position. The method has the following defects: the invention adopts a driving motor with two output shafts to drive two groups of reduction boxes, and the output ends of the reduction boxes are respectively connected with a first driving rod and a second driving rod. The turnout is switched by driving the connecting rod to move in the driving guide groove. The turnout is locked by driving the lock pin through three groups of electric push rods. The switch driving and the locking driving of the turnout are two sets of driving, and the switch driving and the locking driving of the magnetic suspension turnout adopt two sets of independent devices, so that the driving points and the parts are increased, the control is complicated, the cost is increased, the fault points are increased, and the arrangement of the turnout is inconvenient.
